Description
TECHNICAL FIELD

The present disclosure relates to apparatuses, assemblies, and methods for facilitating assembly and disassembly of high-power pumps and, more particularly, to apparatuses, assemblies, and methods for facilitating assembly and disassembly of high-power fluid pumps.


BACKGROUND

Hydraulic fracturing is an oilfield operation that stimulates the production of hydrocarbons, such that the hydrocarbons may more easily or readily flow from a subsurface formation to a well. For example, a hydraulic fracturing system may be configured to fracture a formation by pumping a fracturing fluid into a well at high pressure and high flow rates. Some fracturing fluids may take the form of a slurry including water, proppants, and/or other additives, such as thickening agents and gels. The slurry may be forced via operation of one or more pumps into the formation at rates faster than can be accepted by the existing pores, fractures, faults, or other spaces within the formation. As a result, pressure may build rapidly to the point where the formation may fail and may begin to fracture. By continuing to pump the fracturing fluid into the formation, existing fractures in the formation may be caused to expand and extend in directions away from a well bore, thereby creating additional flow paths for hydrocarbons to flow to the well bore. The proppants may serve to prevent the expanded fractures from closing or may reduce the extent to which the expanded fractures contract when pumping of the fracturing fluid is ceased. Once the formation is fractured, large quantities of the injected fracturing fluid are allowed to flow out of the well, and the production stream of hydrocarbons may be obtained from the formation.


To pump the fracturing fluid into the well bore, a hydraulic fracturing system may include a number of hydraulic fracturing units, each including a prime mover to supply mechanical power and a hydraulic fracturing pump driven by the prime mover. The hydraulic fracturing pump may be supplied with fracturing fluid, and the hydraulic fracturing pump, driven by the prime mover, may pump the fracturing fluid at high-pressure and high flow rates into the wellhead during a fracturing operation. In order to facilitate use of the hydraulic fracturing units and other equipment related to a fracturing operation at different locations, the hydraulic fracturing units may often include a mobile platform, such as a trailer, onto which the prime mover, hydraulic fracturing pump, and other components of the hydraulic fracturing unit may be mounted. The hydraulic fracturing unit may be transported to one wellhead location, set-up for operation, used during the fracturing operation, and once the fracturing operation is completed, it may be partially disassembled for transportation and transported to another wellhead location for use in another fracturing operation.


It may be desirable for the hydraulic fracturing units to be capable of increased pumping capacity. For example, by increasing the pumping capacity of the hydraulic fracturing units, it may be possible to successfully complete a fracturing operation using fewer hydraulic fracturing units, which may lead to reduced set-up and tear-down time, the need for fewer operators, more efficient operation, and more cost-effective completion of the fracturing operation. However, increasing the pumping capacity of the hydraulic fracturing units may result in increasing the size of the hydraulic fracturing pumps in order to increase the output of the hydraulic fracturing pumps. Applicant has recognized that increasing the size of the hydraulic fracturing pumps may render it challenging to assemble and disassemble the hydraulic fracturing pump, for example, during manufacturing or maintenance of the hydraulic fracturing pumps. For example, components of high-power fracturing pumps may be very large dimensionally and may be very heavy, thus rendering the components challenging to assemble, disassemble, and maintain.


Accordingly, Applicant has recognized a need for assemblies, apparatuses, and methods for facilitating the assembly and disassembly of high-power pumps, while mitigating or eliminating possible drawbacks. The present disclosure may address one or more of the above-referenced drawbacks, as well as other possible drawbacks.


SUMMARY

As referenced above, it may be desirable to provide hydraulic fracturing units having higher pumping capacities. Achieving higher pumping capacities may result in the use of high-power pumps to achieve higher pump outputs. Efforts to provide pumps having higher pump outputs may result in relatively larger and heavier pumps. Larger and heavier pumps may include larger and heavier components. Applicant has recognized that this may render it challenging to assemble, disassemble, and maintain such pumps. For example, it may be difficult to lift, properly orient, and/or position relatively larger and heavier components of the pump during assembly, disassembly, and maintenance.


The present disclosure generally is directed to providing assemblies, apparatuses, and methods for assembly and disassembly of high-power pumps. For example, in some embodiments, assemblies, apparatuses, and methods described herein may facilitate lifting, orienting, and/or positioning large pump components during assembly and disassembly of the high-power pumps.


According to some embodiments, a pivoting support assembly for facilitating assembly and disassembly of a high-power pump may include a base and a first support having a first support proximal end and a first support distal end. The first support proximal end and the first support distal end may define therebetween a first longitudinal support axis. The first support proximal end may be connected to the base via a first pivotable support connector, the first support being configured to be connected to a pump frame of the high-power pump, such that a longitudinal pump axis of the high-power pump is substantially parallel to the first longitudinal support axis. The pivoting support assembly may further include a first actuator having a first actuator proximal end connected to the base via a first proximal pivotable actuator connector and a first actuator distal end connected to the first support between the first support proximal end and the first support distal end via a first distal pivotable actuator connector. The first actuator may be positioned to: (a) extend and cause the first support to pivot from a first orientation through a first pivot angle to a second orientation relative to the base, thereby to re-orient the pump frame for installation of a crankshaft of the high-power pump, and (b) retract and cause the first support to pivot from the second orientation toward the first orientation. The pivoting support assembly also may include a second support having a second support proximal end and a second support distal end, the second support proximal end and the second support distal end defining therebetween a second longitudinal support axis. The second support proximal end may be connected to the first support via a second pivotable support connector, the second support being configured to be connected to the pump frame of the high-power pump, such that the longitudinal pump axis of the high-power pump is substantially perpendicular to the second longitudinal support axis. The pivoting support assembly further may include a second actuator having a second actuator proximal end connected to the first support via a second proximal pivotable actuator connector and a second actuator distal end connected to the second support between the second support proximal end and the second support distal end via a second distal pivotable actuator connector.

DETAILED DESCRIPTION

The drawings include like numerals to indicate like parts throughout the several views, the following description is provided as an enabling teaching of exemplary embodiments, and those skilled in the relevant art will recognize that many changes may be made to the embodiments described. It also will be apparent that some of the desired benefits of the embodiments described can be obtained by selecting some of the features of the embodiments without utilizing other features. Accordingly, those skilled in the art will recognize that many modifications and adaptations to the embodiments described are possible and may even be desirable in certain circumstances. Thus, the following description is provided as illustrative of the principles of the embodiments and not in limitation thereof.


The phraseology and terminology used herein is for the purpose of description and should not be regarded as limiting. As used herein, the term “plurality” refers to two or more items or components. The terms “comprising,” “including,” “carrying,” “having,” “containing,” and “involving,” whether in the written description or the claims and the like, are open-ended terms, i.e., to mean “including but not limited to,” unless otherwise stated. Thus, the use of such terms is meant to encompass the items listed thereafter, and equivalents thereof, as well as additional items. The transitional phrases “consisting of” and “consisting essentially of,” are closed or semi-closed transitional phrases, respectively, with respect to any claims. Use of ordinal terms such as “first,” “second,” “third,” and the like in the claims to modify a claim element does not by itself connote any priority, precedence, or order of one claim element over another or the temporal order in which acts of a method are performed, but are used merely as labels to distinguish one claim element having a certain name from another element having a same name (but for use of the ordinal term) to distinguish claim elements.


As noted above, it may be desirable to provide hydraulic fracturing units having higher pumping capacities. Achieving higher pumping capacities may result in the use of high-power pumps to achieve higher pump outputs. Efforts to provide pumps having higher pump outputs may result in relatively larger and heavier pumps. Larger and heavier pumps may include larger and heavier components. Applicant has recognized that this may render it challenging to assemble and disassemble such pumps. For example, it may be difficult to lift, properly orient, position, and/or connect or disconnect relatively larger and heavier components of the pump during assembly and disassembly.


The present disclosure generally is directed to providing assemblies, apparatuses, and methods for assembly, disassembly, and maintenance of high-power pumps. For example, in some embodiments, assemblies, apparatuses, and methods described herein may facilitate lifting, orienting, and/or positioning large pump components during assembly and disassembly of the high-power pumps. For example, FIG. 1 shows a schematic side view of an example hydraulic fracturing unit 10 including an example high-power hydraulic fracturing pump 11, and an example pivoting support assembly 12 for facilitating assembly and disassembly of the high-power pump 11, according to embodiments of the disclosure. FIG. 2 schematically illustrates an example hydraulic fracturing system 14 including a plurality of hydraulic fracturing units 10, according to embodiments of the disclosure. The pump 11 may be any high-power pump, high-pressure pump, reciprocating pump, and/or high-flow rate pump suitable for pumping solids, semi-solids, slurries, liquids, fluids, or combinations thereof. In some embodiments, the pump 11 may be, for example, a hydraulic fracturing pump for pumping hydraulic fracturing fluid. In some embodiments, the pump 11 may be capable of providing a relatively higher pumping capacity while still having physical dimensions enabling transportation of the hydraulic fracturing unit 10 including the hydraulic fracturing pump 11 on public highways, as explained in more detail herein. Alternatively, or in addition, some embodiments of the pump 11 may operate with relatively lower shock magnitude and/or or vibration magnitude resulting from, for example, torque pulses generated by operation of the pump 11. Although embodiments of the pump 11 are described herein as being a “hydraulic fracturing pump” for pumping hydraulic fracturing fluid for the purpose of discussion, the pump 11 may be any other type of pump, such as, for example, any type of high-power pump, high-pressure pump, reciprocating pump, and/or high-flow rate pump suitable for pumping solids, semi-solids, slurries, liquids, fluids, or combinations thereof. In some embodiments, the pump 11 may be, for example, a hydraulic fracturing pump for pumping solids, semi-solids, slurries, liquids, fluids, or combinations thereof, such as hydraulic fracturing fluid.


As shown in FIGS. 1 and 2, in some embodiments, one or more of the hydraulic fracturing units 10 may include a hydraulic fracturing pump 11 driven by a prime mover 16, such as an internal combustion engine. For example, the prime movers 16 may include gas turbine engines (GTEs) or reciprocating-piston engines. In some embodiments, each of the hydraulic fracturing units 10 may include a directly-driven turbine (DDT) hydraulic fracturing pump 11, in which the hydraulic fracturing pump 11 is connected to one or more GTEs that supply power to the respective hydraulic fracturing pump 11 for supplying fracturing fluid at high pressure and high flow rates to a formation. For example, the GTE may be connected to a respective hydraulic fracturing pump 11 via a transmission 18 (e.g., a reduction gearbox) connected to a drive shaft, which, in turn, is connected to a driveshaft or input flange of a respective hydraulic fracturing pump 11, which may be a reciprocating hydraulic fracturing pump. Other types of engine-to-pump arrangements are contemplated as will be understood by those skilled in the art.


In some embodiments, one or more of the GTEs may be a dual-fuel or bi-fuel GTE, for example, capable of being operated using of two or more different types of fuel, such as natural gas and diesel fuel, although other types of fuel are contemplated. For example, a dual-fuel or bi-fuel GTE may be capable of being operated using a first type of fuel, a second type of fuel, and/or a combination of the first type of fuel and the second type of fuel. For example, the fuel may include gaseous fuels, such as, for example, compressed natural gas (CNG), natural gas, field gas, pipeline gas, methane, propane, butane, and/or liquid fuels, such as, for example, diesel fuel (e.g., #2 diesel), bio-diesel fuel, bio-fuel, alcohol, gasoline, gasohol, aviation fuel, and other fuels as will be understood by those skilled in the art. Gaseous fuels may be supplied by CNG bulk vessels, a gas compressor, a liquid natural gas vaporizer, line gas, and/or well-gas produced natural gas. Other types and associated fuel supply sources are contemplated. The one or more prime movers 16 may be operated to provide horsepower to drive the transmission 18 connected to one or more of the hydraulic fracturing pumps 11 to safely and successfully fracture a formation during a well stimulation project or fracturing operation.


In some embodiments, the prime mover 16 may include one or more electric motors. The electric motor may be rated for over 2,000 hp over 5,000 hp, or over 10,000 hp, for example, for the hydraulic fracturing pump 11 to generate a desired pressure and flow rate. The electric motor may include a stator having stator windings for generating a rotating magnetic field at a synchronous speed corresponding to a frequency of a voltage applied to the stator windings. The motor may also include a rotor having rotor windings for interacting with the rotating magnetic field to rotate the rotor. The rotor windings may be configured to generate rotating magnetic poles for interacting with the rotating magnetic field. In one or more embodiments, the electric motor may be an induction electric motor in which the rotating magnetic poles in the rotor are induced by the rotating magnetic field in the stator. In one or more embodiments, the electric motor may be a multi-phase electric motor, such as a three-phase motor, for example.


The electric motor may include a single shaft electric motor or a dual shaft electric motor. In some embodiments, the electric motor and two or more hydraulic fracturing pump 11 may be disposed on a single chassis. For example, the electric a motor may be disposed on a single chassis and arranged between two hydraulic fracturing pumps 11, for example, in manner similar to the pump arrangements described in U.S. Pat. No. 9,395,049, the disclosure of which is incorporated by reference herein in its entirety. In some embodiments, two or more electric motors and two or more hydraulic fracturing pumps 11 may be disposed on a single chassis. For example, a first electric motor may be connected to or otherwise mechanically linked with a first hydraulic fracturing pump 11 and a second electric motor may be connected to or otherwise mechanically linked with a second hydraulic fracturing pump 11, and each of the first and second electric motor and the first and second hydraulic fracturing pump 11 may be disposed on a single chassis and may be arranged in a manner similar to the pump arrangements described in U.S. Pat. No. 11,118,438, the disclosure of which is incorporated by reference herein in its entirety. For example, each electric motor and corresponding hydraulic fracturing pump 11 may be contained as a single module, and a plurality of such modules may be disposed on a single chassis.


In some embodiments, the electric motor may be supplied with a voltage having a fixed frequency or a voltage having a variable frequency. For example, a voltage with a fixed frequency may be applied to a stator of the electric motor and hence the electric motor may be referred to as a “fixed-frequency motor.” Electric power to a motor control center may be supplied by an on-site power source, such as on-site diesel generators, natural gas reciprocating engine generators, or turbine generators, or by an off-site power source, such as a utility grid power. In some embodiments, the motor control center may be disposed with the electric motor and the hydraulic fracturing pump 11 on a single chassis. In some embodiments, a voltage with a variable frequency may be applied to a stator of the electric motor. In some such embodiments, a remotely controllable variable frequency drive (VFD) may be disposed, along with the electric motor(s) and the hydraulic fracturing pump(s) 11, on a single chassis. The VFD may be coupled to or otherwise electrically linked with a power source, for example, as described herein. The VFD may be configured to provide electric power to the one or more electric motors.


In some embodiments, a plurality of electric motors may be connected to or otherwise mechanically linked with a single hydraulic fracturing pump 11. For example, the plurality of electric motors may each be connected to a crankshaft of the hydraulic fracturing pump 11. The plurality of electric motors may include any suitable number of electric motors (e.g., from two electric motors to seven or more electric motors). In some embodiments, at least five electric motors may be coupled to the crankshaft in a manner, such that each electric motor may be positioned about the pump crankshaft axis, so that an output shaft of each electric motor is spaced apart from a longitudinal rotation axis of the crankshaft. For example, the plurality of electric motors may be arranged on or connected to the hydraulic fracturing pump 11 in a manner similar to the electric motor arrangement(s) described in U.S. Publication No. US 2021/0095648 A1, the disclosure of which is incorporated by reference herein in its entirety.


In some embodiments, the fracturing fluid may include, for example, water, proppants, and/or other additives, such as thickening agents and/or gels. For example, proppants may include grains of sand, ceramic beads or spheres, shells, and/or other particulates, and may be added to the fracturing fluid, along with gelling agents to create a slurry, as will be understood by those skilled in the art. The slurry may be forced via the hydraulic fracturing pumps 11 into the formation at rates faster than may be accepted by the existing pores, fractures, faults, or other spaces within the formation. As a result, pressure in the formation may build rapidly to the point where the formation fails and begins to fracture. By continuing to pump the fracturing fluid into the formation, existing fractures in the formation may be caused to expand and extend in directions away from a well bore, thereby creating additional flow paths for hydrocarbons to flow to the well. The proppants may serve to prevent the expanded fractures from closing or may reduce the extent to which the expanded fractures contract when pumping of the fracturing fluid is ceased. Once the well is fractured, large quantities of the injected fracturing fluid may be allowed to flow out of the well, and the water and any proppants not remaining in the expanded fractures may be separated from hydrocarbons produced by the well to protect downstream equipment from damage and corrosion. In some instances, the production stream of hydrocarbons may be processed to neutralize corrosive agents in the production stream resulting from the fracturing process.


In some embodiments, as shown in FIG. 2, the hydraulic fracturing system 14 may include one or more water tanks 20 for supplying water for fracturing fluid, one or more chemical additive units 22 for supplying gels or agents for adding to the fracturing fluid, and/or one or more proppant tanks 24 (e.g., sand tanks) for supplying proppants for the fracturing fluid. The example hydraulic fracturing system 14 shown also includes a hydration unit 26 for mixing water from the water tanks 20 and gels and/or agents from the chemical additive units 22 to form a mixture, for example, gelled water. The example shown also includes a blender 28, which receives the mixture from the hydration unit 26 and proppants via conveyers 30 from the proppant tanks 24. The blender 28 may mix the mixture and the proppants into a slurry to serve as fracturing fluid for the hydraulic fracturing system 14. Once combined, the slurry may be discharged through low-pressure hoses, which convey the slurry into two or more low-pressure lines in a fracturing manifold 32. In the example shown, the low-pressure lines in the fracturing manifold 32 may feed the slurry to the hydraulic fracturing pumps 11 through low-pressure suction hoses, as will be understood by those skilled in the art.


The hydraulic fracturing pumps 11, driven by the respective internal GTEs 16, discharge the slurry (e.g., the fracturing fluid including the water, agents, gels, and/or proppants) at high flow rates and/or high pressures through individual high-pressure discharge lines into two or more high-pressure flow lines, sometimes referred to as “missiles,” on the fracturing manifold 32. The flow from the high-pressure flow lines is combined at the fracturing manifold 32, and one or more of the high-pressure flow lines provide fluid flow to a manifold assembly 34, sometimes referred to as a “goat head.” The manifold assembly 34 delivers the slurry into a wellhead manifold 36. The wellhead manifold 36 may be configured to selectively divert the slurry to, for example, one or more wellheads 38 via operation of one or more valves. Once the fracturing process is ceased or completed, flow returning from the fractured formation discharges into a flowback manifold, and the returned flow may be collected in one or more flowback tanks as will be understood by those skilled in the art.


As schematically depicted in FIG. 2, one or more of the components of the hydraulic fracturing system 14 may be configured to be portable, so that the hydraulic fracturing system 14 may be transported to a well site, quickly assembled, operated for a relatively short period of time, at least partially disassembled, and transported to another location of another well site for use. For example, the components may be connected to and/or supported on a chassis 40, for example, a trailer and/or a support incorporated into a truck, so that they may be easily transported between well sites. In some embodiments, the prime mover 16, the transmission 18, and/or the hydraulic fracturing pump 11 may be connected to the chassis 40. For example, the chassis 40 may include a platform 42, and the transmission 18 may be connected to the platform 42, and the prime mover 16 may be connected to the transmission 18. In some embodiments, the prime mover 16 may be connected to the transmission 18 without also connecting the prime mover 16 directly to the platform 42, which may result in fewer support structures being needed for supporting the prime mover 16, transmission 18, and/or hydraulic fracturing pump 11 on the chassis 40.


In some embodiments, two or more hydraulic fracturing pumps 11 may be connected to the chassis 40. For example, the chassis 40 may include the prime mover 16 disposed or situated between two hydraulic fracturing pumps 11. In such examples, the prime mover 16 may be a dual-shaft electric motor, and each output shaft of the motor is connected to one of the hydraulic fracturing pumps 11. In some embodiments, the chassis 40 may include a plurality of prime movers 16 and hydraulic fracturing pumps 11. For example, the chassis 40 may include a first prime mover 16 mechanically linked to a first hydraulic fracturing pump 11 and a second prime mover 16 mechanically linked to a second hydraulic fracturing pump 11.


As shown in FIG. 2, some embodiments of the hydraulic fracturing system 14 may include one or more fuel supplies 44 for supplying the prime movers 16 and any other fuel-powered components of the hydraulic fracturing system 14, such as auxiliary equipment, with fuel. The fuel supplies 44 may include gaseous fuels, such as compressed natural gas (CNG), natural gas, field gas, pipeline gas, methane, propane, butane, and/or liquid fuels, such as, for example, diesel fuel (e.g., #2 diesel), bio-diesel fuel, bio-fuel, alcohol, gasoline, gasohol, aviation fuel, and other fuels, as will be understood by those skilled in the art. Gaseous fuels may be supplied by CNG bulk vessels, such as fuel tanks coupled to trucks, a gas compressor, a liquid natural gas vaporizer, line gas, and/or well-gas produced natural gas. The fuel may be supplied to the hydraulic fracturing unit 10 by one of more fuel lines supplying the fuel to a fuel manifold and unit fuel lines between the fuel manifold and the hydraulic fracturing units 10. Other types and associated fuel supply sources and arrangements are contemplated as will be understood by those skilled in the art.


As shown in FIG. 2, some embodiments also may include one or more data centers 46 configured to facilitate receipt and transmission of data communications related to operation of one or more of the components of the hydraulic fracturing system 14. Such data communications may be received and/or transmitted via hard-wired communications cables and/or wireless communications, for example, according to known communications protocols. For example, the data centers 46 may contain at least some components of a hydraulic fracturing control assembly, such as a supervisory controller configured to receive signals from components of the hydraulic fracturing system 14 and/or communicate control signals to components of the hydraulic fracturing system 14, for example, to at least partially control operation of one or more components of the hydraulic fracturing system 14, such as, for example, the prime movers 16, the transmissions 18, and/or the hydraulic fracturing pumps 11 of the hydraulic fracturing units 10, the chemical additive units 22, the hydration units 26, the blender 28, the conveyers 30, the fracturing manifold 32, the manifold assembly 34, the wellhead manifold 36, and/or any associated valves, pumps, and/or other components of the hydraulic fracturing system 14.



FIG. 3A is a schematic side view of an example hydraulic fracturing unit 10, according to embodiments of the disclosure, and FIG. 3B is a schematic end view of the example hydraulic fracturing unit 10 shown in FIG. 3A, according to embodiments of the disclosure. As shown in FIG. 3A, in some embodiments, the transmission 18 may include a transmission input shaft 48 connected to a prime mover output shaft 50 (e.g., a turbine output shaft), such that the transmission input shaft 48 rotates at the same rotational speed as the prime mover output shaft 50. The transmission 18 may also include a transmission output shaft 52 positioned to be driven by the transmission input shaft 48 at a different rotational speed than the transmission input shaft 48. In some embodiments, the transmission 18 may be a reduction transmission, such as a reduction gearbox, which results in the transmission output shaft 52 having a relatively slower rotational speed than the transmission input shaft 48. The transmission 18 may include a continuously variable transmission, an automatic transmission including one or more planetary gear trains, for example, as described herein, a transmission shiftable between different ratios of input-to-output, etc., or any other suitable of types of transmissions, as will be understood by those skilled in the art.


As shown in FIG. 3A, in some embodiments, the hydraulic fracturing pump 11 may be, for example, a reciprocating fluid pump, as explained herein. In some embodiments, the hydraulic fracturing pump 11 may include a pump drive shaft 54 connected to the transmission output shaft 52, such that the transmission output shaft 52 drives the pump drive shaft 54 at a desired rotational speed. For example, the transmission output shaft 52 may include an output shaft connection flange, and the pump drive shaft 54 may include a drive shaft connection flange, and the output shaft connection flange and the drive shaft connection flange may be coupled to one another, for example, directly connected to one another. In some embodiments, the transmission output shaft 52 and the pump drive shaft 54 may be connected to one another via any known coupling types as will be understood by those skilled in the art (e.g., such as a universal joint and/or a torsional coupling).


As shown in FIG. 3A, in some embodiments, the chassis 40 may be or include a trailer 56 including the platform 42 for supporting components of the hydraulic fracturing unit 10, one or more pairs of wheels 58 facilitating movement of the trailer 56, a pair of retractable supports 60 to support the hydraulic fracturing unit 10 during use, and a tongue 62 including a coupler 64 for connecting the trailer 56 to a truck for transport of the hydraulic fracturing unit 10 between well sites to be incorporated into a hydraulic fracturing system 14 of a well site fracturing operation, as will be understood by those skilled in the art.


As shown in FIGS. 1, 2, 3A, and 3B, some embodiments of the hydraulic fracturing unit 10 may include an enclosure 66 connected to and supported by the chassis 40 according to embodiments of the disclosure. In some embodiments, as shown in FIGS. 1 and 3A, the prime mover 16 may be connected to the transmission 18 via the prime mover output shaft 50 and the transmission input shaft 48, both of which may be substantially contained within the enclosure 66 (shown without doors or side panels to provide a view of the interior of the enclosure 66). The prime mover 16 may include an air intake duct 68 and a turbine exhaust duct 70 (e.g., when the prime mover is a GTE) passing through walls of the enclosure 66 and connected to the prime mover 16. The prime mover 16 may be connected to the hydraulic fracturing pump 11 via the transmission 18, with the transmission output shaft 52 connected to the pump drive shaft 54, for example, as explained herein.


As shown in FIGS. 1, 3A, and 3B, some embodiments of the hydraulic fracturing pump 11 may have physical dimensions configured such that the hydraulic fracturing pump 11 does not exceed the space available on the platform 42, for example, while still providing a desired pressure output and/or flow output to assist with performing the fracturing operation as explained herein. For example, referring to FIG. 3A, the hydraulic fracturing pump 11 may have a pump length dimension L substantially parallel to a longitudinal axis X of the platform 42 that facilitates placement and/or connection of the hydraulic fracturing pump 11 on the platform 42, for example, without causing the hydraulic fracturing unit 10 to exceed a length permitted for transportation on public highways, for example, in compliance with government regulations. The pump length dimension L of the hydraulic fracturing pump 11 may be greater than one meter (m). In some embodiments, the pump length dimension L may be from about 0.5 m to about 3 m, from about 0.75 m to about 2.5 m, or from about 1 m to about 2 m.


In some embodiments, for example, as shown in FIG. 3B, the hydraulic fracturing pump 11 may have a pump width dimension W substantially perpendicular to a longitudinal axis X of the platform 42 that facilitates placement and/or connection of the hydraulic fracturing pump 11 on the platform 42, for example, without causing the hydraulic fracturing unit 10 to exceed a width permitted for transportation on public highways, for example, in compliance with government regulations. For example, the hydraulic fracturing pump 11 may have a pump width W perpendicular to the longitudinal axis X of the platform, such that the pump width W is less than or equal to the width of the platform WP, for example, as shown in FIG. 3B. In some embodiments, the pump width W may be at least 50%, at least 75%, or at least 90% of the width of the platform WP. For example, a ratio of the pump width W to the width of the platform WP, expressed as W:WP, may be from about 0.8:1, about 0.9:1, about 0.93:1, or about 0.95:1 to about 0.98:1, about 1:1, about 1.05:1, or about 1.1 to 1. As shown in FIG. 3B, in some embodiments, as viewed from the rear of the platform 42 and in a direction substantially parallel to the longitudinal axis X of the platform 42, an end of the hydraulic fracturing pump 11 may take on the appearance of an inverted V, as explained in more detail herein.



FIG. 4A is a schematic perspective view of an example hydraulic fracturing pump 11, according to embodiments of the disclosure. As shown in FIG. 3A, in some embodiments, the hydraulic fracturing pump 11 may include a single power end 72 and respective first and second fluid ends 74a and 74b connected to the single power end 72. For example, the single power end 72 may include a pump frame 76, the crankshaft 78, and/or plungers 84 and/or 88. The first fluid end 74a and the second fluid end 74b may each be connected to the pump frame 76, for example, on opposite lateral sides of the hydraulic fracturing pump 11. In some embodiments, for example, as shown in FIGS. 3A, 3B, and 4A, the first and second fluid ends 74a and 74b may be connected to the hydraulic fracturing pump 11, and the hydraulic fracturing pump 11 may be connected to the platform 42, such that the first and second fluid ends 74a and 74b are closer to the platform 42 than the power end 72. For example, the first and second fluid ends 74a and 74b may be relatively closer to the ground than if the hydraulic fracturing pump 11 was oriented such that the first and second fluid ends 74a and 74b were farther away from the platform 42 than the power end 72. The example orientation shown may render the fluid ends 74a and 74b relatively more easily accessible to operators and/or maintenance service personal, for example, during set-up of the hydraulic fracturing unit 10 for a fracturing operation, take-down of the hydraulic fracturing unit 10, for example, once a fracturing operation is completed, and/or during maintenance or service of the hydraulic fracturing unit 10.



FIG. 4B is a schematic top view of the example hydraulic fracturing pump 11 shown in FIG. 4A, and FIG. 4C is a schematic bottom view of the example hydraulic fracturing pump 11 shown in FIG. 4A and FIG. 4B, according to embodiments of the disclosure. FIG. 4D is a schematic end view of the example hydraulic fracturing pump 11 shown in FIG. 4A, according to embodiments of the disclosure.


As shown in FIGS. 4A, 4B, 4C, and 4D, in some embodiments, the hydraulic fracturing pump 11 may include the pump frame 76, which may at least partially define a shaft aperture 77 (see, e.g., FIG. 9A), and a crankshaft 78 extending through the shaft aperture 77. In some embodiments, the pump frame 76 may include a plurality of pump frame sections 80, and each of the pump frame sections 80 may at least partially define the shaft aperture(s) 77. For example, as shown in FIG. 4A, the example pump frame 76 includes five pump frame sections 80a, 80b, 80c, 80d, and 80e. Pump frames 76 having different numbers of pump frame sections 80 are contemplated. For example, the hydraulic fracturing pump 11 may include the pump frame 76, which may include any suitable number of pump frame sections 80. In some embodiments, the hydraulic fracturing pump 11 may include from two, three, four, five, six, eight, ten, or twelve pump frame sections 80. As shown in FIG. 4D, one or more of the pump frame sections 80 may have an inverted V-shaped cross-section as viewed in a direction substantially parallel to a longitudinal axis of the crankshaft CR. In some embodiments, one or more of the pump frame sections 80 may have an upright V-shaped cross-section as viewed in a direction substantially parallel to a longitudinal axis of the crankshaft CR. In some embodiments, one or more of the pump frame sections 80 may be connected to one another to form the pump frame 76, for example, via frame connectors 82 and/or the first and second fluid ends 74a and 74b. Though first and second fluid ends 74a and 74b are shown, the hydraulic fracturing pump 11 may include three or more fluid ends. In some embodiments, the hydraulic fracturing pump 11 may include at least three fluid ends and at least three corresponding banks of plungers. For example, one or more pump frame sections 80 may have an inverted Y-shaped cross-section as viewed in a direction substantially parallel to a longitudinal axis of the crankshaft CR, wherein the third fluid end is disposed above the crankshaft 78. In other embodiments, the fracturing pump 11 may include four fluid ends and four corresponding banks of plungers. For example, one or more pump frame sections may have an X-shaped cross-section as viewed in a direction substantially parallel to a longitudinal axis of the crankshaft CR, wherein the third fluid end is disposed above the first fluid end 74a, and the fourth fluid end is disposed above the second fluid end 74b.


As shown in FIGS. 4A, 4B, 4C, and 4D, in some embodiments, the hydraulic fracturing pump 11 may include a plurality of first plungers 84 connected to the crankshaft 78 and positioned to reciprocate relative to the crankshaft 78 as the crankshaft 78 rotates. For example, as shown in FIGS. 4B and 4C, the hydraulic fracturing pump 11 may include a first bank 86 of four first plungers 84a, 84b, 84c, and 84d. In addition, in some embodiments, the hydraulic fracturing pump 11 may include a plurality of second plungers 88 connected to the crankshaft 78 and positioned to reciprocate relative to the crankshaft 78 as the crankshaft 78 rotates. For example, as shown in FIGS. 4B and 4C, the hydraulic fracturing pump 11 may include a second bank 90 of four second plungers 88a, 88b, 88c, and 88d. Though four first plungers 84 and four second plungers 88 are shown, the hydraulic fracturing pump 11 may include any suitable number of first and second plungers 84 and 88. In some embodiments, the hydraulic fracturing pump 11 may include from two, three, four, five, six, eight, ten, or twelve first plungers 84 and from two, three, four, five, six, eight, ten, or twelve second plungers 88.


Each of the of first plungers 84 may be configured to reciprocate and draw-in fracturing fluid at a first pressure and discharge the fracturing fluid at a second pressure greater than the first pressure. Each of the second plungers 88 may be configured to reciprocate and draw-in fracturing fluid at a third pressure and discharge the fracturing fluid at a fourth pressure greater than the third pressure. For example, the first pressure and/or the third pressure may be substantially equal to a pressure associated with the fracturing fluid being supplied to the hydraulic fracturing pump 11 from the blender 28 (see FIG. 2). The second pressure and the fourth pressure may be substantially equivalent to the high pressure of the fracturing fluid being supplied to the wellhead 38 by operation of the prime mover 16, the transmission 18, and the hydraulic fracturing pump 11 of the hydraulic fracturing unit 10. In some embodiments, the first pressure and the third pressure may be substantially the same. In some embodiments, the second pressure and the fourth pressure may be substantially the same. In some embodiments, the first pressure and the third pressure may be different, and/or the second pressure and the fourth pressure may be different.


In some embodiments, for example, as shown in FIG. 4D, each of the first plungers 84 may reciprocate in a first plane P1 and draw-in fracturing fluid at the first pressure and discharge the fracturing fluid at the second pressure, and/or each of the second plungers 88 may reciprocate in a second plane P2 and draw-in fracturing fluid at the third pressure and discharge the fracturing fluid at the fourth pressure. In some embodiments, the first plane P1 and the second plane P2 may intersect at the crankshaft axis CR and/or define an offset angle A between the first plane P1 and the second plane P2. For example, the offset angle A may range from zero degrees to three hundred-sixty degrees, for example, from about ten degrees to about three hundred degrees, from about thirty degrees to about one two hundred-seventy degrees, or from about forty-five degrees to about one hundred-eighty degrees. In some embodiments, the offset angle A between the first plane P1 and the second plane P2 may be a non-zero offset angle. For example, the offset angle A may range from about thirty degrees to about one hundred-eighty degrees, for example, from about ninety degrees to about one hundred-eighty degrees, from about thirty degrees to about one hundred-fifty degrees, from about forty-five degrees to about one hundred thirty-five degrees, from about sixty degrees to about one hundred-twenty degrees, or from about seventy-five degrees to about one hundred-five degrees, for example, about ninety degrees.


In some embodiments, providing the first and second plungers 84 and 88 in different planes may result in increasing the pumping capacity of the hydraulic fracturing pump 11, for example, without substantially increasing the physical dimensions of the hydraulic fracturing pump 11, for example, without substantially increasing the pump length L and/or without substantially increasing the pump width W. In some embodiments, providing the first and second plungers 84 and 88 in different planes may result in relatively reducing the level of shock and/or vibration associated with operation of the hydraulic fracturing pump 11, for example, the level of shock and/or vibration associated with torque shock and/or torque vibration generated during operation of the hydraulic fracturing pump 11, for example, as each of the first plungers 84 and/or each of the second plungers 88 discharges fracturing fluid at the second and fourth pressures, respectively. For example, in some embodiments, the shock and/or torque generated by one or more of the first plungers 84 and/or one or more of the second plungers 88 may substantially offset or cancel one another.


As shown in FIGS. 4B and 4C, in some embodiments, the crankshaft 78 may include a plurality of crankpins 92, and each of the crankpins 92 may be substantially parallel to and offset from a longitudinal rotation axis RA of the crankshaft 78. In some embodiments, the crankshaft axis CR and the longitudinal rotation axis RA may be substantially co-existent. The crankpins 92 may be spaced from, but parallel to, the longitudinal rotation axis RA, such that as the crankshaft 78 rotates, the first plungers 84 and the second plungers 88 are caused to reciprocate, for example, in respective chambers of the first and second fluid ends 74a and 74b, for example, a distance equal to two times the offset of the respective crankpin 92 to which the plunger 84 or 88 is connected. In some embodiments, one or more of the crankpins 92 may be radially spaced from one another, for example, such that the respective reciprocations of the plungers occur according to a desired timing relative to one another. The crankshaft 78 may include any suitable number of crankpins 92. In some embodiments, the crankshaft 78 may include one, two, three, four, five, six, eight, ten, or twelve or more crankpins 92. For example, in the embodiment shown in FIGS. 4B and 4C, the example crankshaft 78 includes four crankpins 92. In some embodiments, each of the crankpins 92 may be radially offset relative to one another by, for example, ninety degrees. This may result in the respective reciprocations of the plungers being spaced from one another. The spacing of the plunger reciprocations may result in at least some force cancellation due to the plungers 84 and 88 moving in different directions as more fully described below.


As shown in FIGS. 4B and 4C, in some embodiments, the hydraulic fracturing pump 11 may include a plurality of connecting rods 94. In some embodiments, the plurality of connecting rods 94 may include from two, three, four, five, six, eight, ten, twelve, sixteen, twenty, or twenty-four or more connecting rods 94. For example, each of connecting rods 94 may connect one of the first plungers 84 to each of the plurality of crankpins 92 or one of the second plungers 88 to each of the of crankpins 92, for example, such that each of the crankpins 92 is connected to one of the first plungers 84 and one of the second plungers 88. For example, each of the connecting rods 94 may include an elongated rod body defining a longitudinal rod axis and having a crosshead end connected to either one of the first plungers 84 or one of the second plungers 88, and a crank end connected to one of the crankpins 92. For example, each of the crosshead ends may be connected to a respective intermediate connector, such as, for example, a pony rod, which, in turn, may be connected to a respective plunger (84 or 88). In some embodiments, each crosshead end of a corresponding connecting rod 94 may be connected to a corresponding crosshead via a pin that permits the crosshead to pivot with respect to the respective connecting rod 94 as the crosshead reciprocates, and a respective plunger to which the crosshead is connected reciprocates in a chamber of a respective fluid end (74a or 74b), and each of the respective crank ends of the connecting rod 94 may be connected to a respective crankpin 92, such that the crankpin 92 is able to rotate freely relative to the respective crank end as the crankshaft 78, driven by the prime mover 16 and/or the transmission 18, rotates. As shown in FIGS. 4B and 4C, in some embodiments, a plurality of the connecting rods 94 may have a longitudinal rod axis offset from a longitudinal rod axis of another plurality of the connecting rods 94.


In some embodiments, the crankshaft 78 and/or the crankpins 92 may be configured such that different pairs of the first and second plungers 84 and 88 are in different locations along their respective stroke paths as the crankshaft 78 rotates. In some embodiments, the crankshaft 78 and/or the crankpins 92 may be configured such that different pairs of first and second plungers 84 and 88 of the first and second banks of plungers 86 and 90 and are offset by the crankpins 92, for example, in some embodiments, the plungers of the first and third pairs of plungers shown in the drawings may be offset from each other by the crankpins 92 by about ninety degrees, for example, and may move in different directions, for example, along an intake stroke direction toward the crankshaft 78 for drawing-in fracturing fluid and a discharge stroke direction away from the crankshaft 78 for discharging fracturing fluid. For example, a first pair of plungers may include a first one of the first plungers 84 (e.g., first plunger 84a) and a first one of the second plungers 88 (e.g., second plunger 88a), and a second pair of plungers may include a second one of the first plungers 84 (e.g., first plunger 84b) and a second one of the second plungers 88 (e.g., second plunger 88b), and the crankshaft 78 may be configured such that the first pair of plungers moves in a first direction to discharge at least a portion of the fracturing fluid while the second pair of plungers moves in a second direction to draw-in at least a portion of the fracturing fluid. In some embodiments, each of the pairs of first and second plungers 84 and 88 may be connected to a common crankpin 92 of the crankshaft 78. In some embodiments, different pairs and/or additional pairs of the first and second plungers 84 and 88 may similarly move in different directions. This example movement of plunger pairs in different directions may result in relatively reducing the level of shock and/or vibration associated with operation of the hydraulic fracturing pump 11, for example, the level of shock and/or vibration associated with torque shock and/or torque vibration generated during operation of the hydraulic fracturing pump 11, for example, as each of the first plungers 84 and/or each of the second plungers 88 discharges fracturing fluid at the second and fourth pressures, respectively. For example, in some embodiments, the shock and/or torque generated by one or more of the pairs of first and second plungers 84 and 88 may substantially offset or cancel one another.


As shown in FIGS. 4A, 4B, 4C, and 4D, in some embodiments, the hydraulic fracturing pump 11 may include a first pinion gear 96 engaged with the crankshaft 78, for example, via a first drive gear 98, at a first end 100 of the pump frame 76, and a connector shaft 102 connected to the first pinion gear 96. In some embodiments, the hydraulic fracturing pump 11 also may include a second pinion gear 104 connected to the hydraulic fracturing pump 11 at a second end 106 of the pump frame 76 and connected to the first pinion gear 96 via the connector shaft 102. In some such embodiments, the first pinion gear 96 may drive the connector shaft 102 and the crankshaft 78 at the first end 100 of the pump frame 76. The connector shaft 102 may transfer the torque from the first pinion gear 96 and drive the second pinion gear 104 at the second end 106 of the pump frame 76. The second pinion gear 104 may drive the crankshaft 78 at the second end 106 of the pump frame 76, for example, via a second drive gear 108.


In some such embodiments, because the crankshaft 78 is driven at both ends, the torque tending to twist the crankshaft 78 may be relatively reduced as compared to a crankshaft that is driven at one end. This may result in an ability to drive the crankshaft 78 with relatively more torque and/or power without damaging the crankshaft 78 (e.g., for a crankshaft of a given strength) and/or adversely affecting operation of the hydraulic fracturing pump 11. In some embodiments, the hydraulic fracturing pump 11 may be configured to be driven by one or more prime movers 16 located at opposite ends of the hydraulic fracturing pump 11. For example, the hydraulic fracturing pump 11 may be driven by one or more prime movers 16 from each of both the first end 100 and the second end 106 of the pump frame 76, for example, via the first pinion gear 96 and the second pinion gear 104. For example, a second prime mover may be connected to the hydraulic fracturing pump 11 at an end of the hydraulic fracturing pump 11 opposite a first prime mover 16, for example, via a second transmission, to supply power to the hydraulic fracturing pump 11.


During operation of the hydraulic fracturing pump 11, the prime mover 16 of the hydraulic fracturing unit 10 may supply power, so as to drive rotation of the crankshaft 78, and as the crankshaft 78 is rotated, the first plungers 84 of the first bank of plungers 86 and the second plungers 88 of the second bank of plungers 90 accordingly will be reciprocated in an alternating fashion in opposite directions toward and away from respective fluid chambers of their respective fluid ends 74a and 74b. For example, one or more of the first plungers 84 of the first bank of plungers 86 may be moved in a first, substantially downward direction along a discharge stroke, so as to discharge at least a portion of fracturing fluid contained within the chamber of the first fluid end 74a. The discharged fluid may be directed out of the respective chamber of the first fluid end 74a and via a fluid output conduit 110a (FIGS. 4B and 4C). Substantially simultaneously or concurrently, one or more of second plungers 88 of the second bank of plungers 90 may be moved in a second, substantially upward direction along an intake stroke to draw-in at least a portion of fracturing fluid into the respective chamber of the second fluid end 74b. The fracturing fluid may be drawn into the chamber via a fluid inlet conduit 112b, which may be fluidly connected to a source or supply of the fracturing fluid (see, e.g., FIG. 2). Thereafter, as the crankshaft 78 continues to rotate, one or more of the second plungers 88 of the second bank of plungers 90 may be moved in a substantially downward direction along a discharge stroke, so as to discharge at least a portion of fracturing fluid contained within the chamber of the second fluid end 74b. The discharged fluid may be directed out of the respective chamber of the second fluid end 74b and via a fluid output conduit 110b. Substantially simultaneously or concurrently, one or more of first plungers 84 of the first bank of plungers 86 may be moved in a substantially upward direction along an intake stroke to draw-in at least a portion of fracturing fluid into the respective chamber of the first fluid end 74a. The fracturing fluid may be drawn into the chamber via a fluid inlet conduit 112a, which may be fluidly connected to a source or supply of the fracturing fluid. In some embodiments, different pairs and/or multiple pairs of the first and second plungers 84 and 88 may be configured to similarly move in different directions, which may further help reduce a level of shock and/or vibration associated with the operation of the hydraulic fracturing pump 11, such as when each of the first plungers 84 and/or each of the second plungers 88 discharges the fracturing fluid at different pressures.


As noted above, high-power pumps, such as, for example, those described above with respect to FIGS. 1-4D, may be configured (e.g., sized) to achieve relatively higher pump outputs. As a result, such high-power pumps may be relatively larger and heavier, for example, as noted herein, even though, in at least some embodiments, the high-power pumps may be transportable between different geographic locations. Larger and heavier pumps, however, may include larger and heavier components, and thus, Applicant has recognized that this may render it challenging to assemble and disassemble such pumps. For example, it may be difficult to lift, properly orient, position, and/or assemble relatively larger and heavier components of the pump during assembly, disassembly, and/or maintenance. At least some embodiments of the assemblies, apparatuses, and methods described herein may be used for assembly and disassembly of high-power pumps. For example, in some embodiments, assemblies, apparatuses, and methods described herein may facilitate lifting, orienting, and/or positioning large pump components during assembly and disassembly of the high-power pumps.



FIG. 5 is a schematic partial perspective side view of an example hydraulic fracturing unit 10 including an example high-power hydraulic fracturing pump 11, according to embodiments of the disclosure, and FIG. 6 is a schematic perspective end view of an example high-power hydraulic fracturing pump 11, according to embodiments of the disclosure. FIG. 7 is a schematic perspective side view of a pivoting support assembly 12 for facilitating assembly and disassembly of a high-power pump, for example, such as those described herein, according to embodiments of the disclosure.


As shown in FIG. 7, the pivoting support assembly 12, in at least some embodiments, may include a base 120 and a first support 122 having a first support proximal end 124 and a first support distal end 126, and a second support 128 having a second support proximal end 130 and a second support distal end 132. FIGS. 8A, 8B, and 8C are schematic perspective side views of the pivoting support assembly 12 shown in FIG. 7, with the first support 122 pivoted relative to the base and the second support 128 pivoted relative to the first support 122. As described herein, in some embodiments, the first support 122 and/or the second support 128 may be pivoted relative to the base 120 and/or first support 122 in a manner that facilitates assembly, disassembly, or maintenance of components of a high-power pump, such as, for example, the example high-power pump 11 described herein.


As shown in FIGS. 7, 8B, and 8C, in some embodiments, the base 120 may include a cross-brace 134 extending transverse to a longitudinal axis B of the base 120. Some embodiments of the base 120 further may include a pair of first support legs 136 extending from the cross-brace 134 in a direction substantially parallel to the longitudinal axis B of the base 120, and a pair of second support legs 138 extending from the cross-brace 134 in a direction substantially parallel to the longitudinal axis B of the base 120 and in a direction opposite the pair of first support legs 136. The cross-brace 134, the first support legs 136, and/or the second support legs 138 may provide a substantially planar platform on which the base 120 may be supported on a surface, such as the ground or other stable support.


In some embodiments, the base 120 may include one or more fixtures 140 for facilitating movement of the pivoting support assembly 12, for example, using a fork truck and/or crane. For example, as shown, in FIG. 7, the fixtures 140 may include one or more sleeves extending transverse to the longitudinal axis B of the base 120. The sleeves may be configured to receive a fork of a fork truck. Other types of fixtures 140 for facilitating movement of the base 120 are contemplated and may include hooks, for example, facilitating attachment to a hoist or crane.


According to some embodiments, one or more of the first support legs 136 may include a clearance 142 configured to provide space for a pump, for example, when the pump is being pivoted relative to the base 120 into an orientation and/or position for assembly or disassembly of components, for example, as shown in FIGS. 9D and 10C. In some embodiments, the second support legs 138 may be connected to the cross-brace 134 such that the second support legs 138 are spaced from opposite ends of the cross-brace 134. This may provide space for additional components of the base 120, for example, as described herein.


As shown in, for example, FIG. 8B, the first support proximal end 124 and the first support distal end 126 of the first support 122 define therebetween a first longitudinal support axis FS, and the second support proximal end 130 and the second support distal end 132 of the second support 128 define therebetween a second longitudinal support axis SS. In at least some embodiments, the first longitudinal support axis FS, the second longitudinal support axis SS, and/or the longitudinal axis B of the base 120 may be substantially parallel to one another, for example, when in the example condition and relative orientations shown in FIG. 7, for example, prior to movement or re-orientation of the first support 122 relative to the base 120, prior to movement or re-orientation of the second support 128 relative to the base 120, and/or prior to movement or re-orientation of the second support 128 relative to the first support 122. As explained in more detail herein, in some embodiments, as the first support 122 pivots relative to the base 120, the first longitudinal support axis FS may pivot through a plane substantially aligned with the longitudinal axis B of the base 120 (e.g., a substantially vertical plane), for example, such that the longitudinal axis B lies within the plane. In some embodiments, as the second support 128 pivots relative to the base 120 and/or the first support 122, the second longitudinal support axis SS may pivot through a plane substantially aligned with the longitudinal axis B of the base 120 and/or the first longitudinal support axis FS (e.g., a substantially vertical plane), for example, such that, respectively, the longitudinal axis B and/or the first longitudinal support axis FS lie(s) within the plane.


As shown in, for example, FIGS. 7 and 8A-8C, in at least some embodiments, the first support proximal end 124 may be connected to the base 120 via a first pivotable support connector 144. For example, as shown, a pair of first hinges 146 may be connected to the base 120, for example, at the cross-brace 134, and to the first support proximal end 124 of the first support 122. For example, the first support 122 may include a pair of first support side frame members 148, and ends of the first support side frame members 148 at the first support proximal end 124 may each be connected to the one of the first hinges 146. The first support 122, according to some embodiments, further may include a first support distal cross brace 150 connected to ends of each of the first support side frame members 148 at the first support distal end 126 of the first support 122. As shown, at least some embodiments of the first support 122 further may include a first support proximal cross-brace 152 and a first support medial cross-brace 154, each extending between and connected to each of the first support side frame members 148.


As shown in, for example, FIGS. 7 and 8A-8C, in at least some embodiments, the second support proximal end 130 of the second support 128 may be connected to the first support 122 via a second pivotable support connector 156. For example, as shown, a pair of second hinges 158 may be connected to the first support 122, for example, at the first support medial cross-brace 154, and to the second support proximal end 130 of the second support 128. For example, the second support 128 may include a pair of second support side frame members 160, and ends of the second support side frame members 160 at the second support proximal end 130 may each be connected to the one of the second hinges 158. The second support 128, according to some embodiments, further may include a second support distal end frame member 162 connected to ends of each of the second support side frame members 160 at the second support distal end 132 of the second support 128. As shown, at least some embodiments of the second support frame 128 further may include a second support proximal cross-brace 164 extending between and connected to each of the second support side frame members 160.


As shown in FIGS. 7 and 8A-8C, at least some embodiments of the pivoting support assembly 12 further may include a first actuator 166 having a first actuator proximal end 168 connected to the base 120 via a first proximal pivotable actuator connector 170 (e.g., a hinge or hinge-like structure) and a first actuator distal end 172 connected to the first support 122 between the first support proximal end 124 and the first support distal end 126 via a first distal pivotable actuator connector 174 (e.g., a hinge or hinge-like structure). For example, some embodiments may include a pair of first actuators 166 and associated connections, with each of the first actuators 166 being hingedly connected to the cross-brace 134 of the base 120 and hingedly connected to one of the first support side frame members 148, for example, as shown.


As shown in FIGS. 7 and 8A-8C, the one or more first actuators 166 may be configured to (a) extend and cause the first support 122 to pivot from a first orientation through a first pivot angle to a second orientation relative to the base 120, thereby to re-orient the first support 122 and a pump frame for installation of, for example, a crankshaft of the high-power pump, and (b) retract and cause the first support 122 to pivot from the second orientation toward the first orientation. For example, as described herein (see FIGS. 9A-9D), the pump frame may be connected to the first support 122, such that the longitudinal axis of the pump frame is substantially aligned with or substantially parallel to the longitudinal axis FS of the first support 122. The one or more first actuators 166 may be configured to extend and cause the first support 122 to pivot from a first orientation (e.g., as shown in FIG. 9A) through a first pivot angle to a second orientation relative to the base 120 (e.g., as shown in FIG. 9C), thereby to re-orient the first support 122 and a pump frame for installation of, for example, a crankshaft of the high-power pump.


As shown in FIGS. 7 and 8A-8C, at least some embodiments of the pivoting support assembly 12 also may include a second actuator 176 having a second actuator proximal end 178 connected to the first support 122 via a second proximal pivotable actuator connector 180 (e.g., a hinge or hinge-like structure) and a second actuator distal end 182 connected to the second support 128 between the second support proximal end 130 and the second support distal end 132 via a second distal pivotable actuator connector 184 (e.g., a hinge or hinge-like structure). For example, some embodiments may include a pair of second actuators 176 and associated connections, with each of the second actuators 176 being hingedly connected to the first support medial cross-brace 154 of the first support 122 and hingedly connected to one of the second support side frame members 160, for example, as shown.


As shown in FIGS. 7 and 8A-8C, the one or more second actuators 176 may be configured to (a) extend and cause the second support 128 to pivot from a third orientation through a second pivot angle to a fourth orientation relative to the first support 122, thereby to re-orient the second support 128 and a pump frame for installation of, for example, a connecting rod of the high-power pump, and (b) retract and cause the second support 128 to pivot from the fourth orientation toward the third orientation. For example, as described herein (see FIGS. 10A-10D), the pump frame may be connected to the second support 128, such that the longitudinal axis of the pump frame 76 is substantially transverse with, or substantially perpendicular to, the longitudinal axis SS of the second support 122. The one or more second actuators 176 may be configured to extend and cause the second support 128 to pivot from the third orientation (e.g., as shown in FIG. 10A) through the second pivot angle to the fourth orientation (e.g., as shown in FIG. 10C) relative to the first support 122, thereby to re-orient the second support 128 and a pump frame for installation of, for example, a connecting rod of the high-power pump.


As described herein, for example, with respect to FIGS. 9A-9C and FIGS. 10A-10D, at least some embodiments of the pivoting support assembly 12 may be used to facilitate assembly and disassembly of high-power pumps. For example, the pivoting support assembly 12 may be used to lift, properly orient, position, and/or assemble relatively larger and heavier components of a high-power pump, for example, during assembly, disassembly, and/or maintenance related to the high-power pump.


In some embodiments, the pivoting support assembly 12 may be configured to lift and re-orient a high-power pump to facilitate assembly or disassembly of components of the high-power pump. For example, the first support 120 may be configured to pivot from a first orientation through a first pivot angle, relative to the base 120, to a second orientation relative to the base 120, thereby to re-orient the pump frame for installation of a crankshaft of the high-power pump. In some embodiments, the first pivot angle may range from about 45 degrees to about 100 degrees, from about 45 degrees to about 90 degrees, from about 60 degrees to about 90 degrees, from about 70 degrees to about 90 degrees, or from about 80 degrees to about 90 degrees. This may facilitate inserting a crankshaft into the pump frame, for example, vertically, as described herein. In some embodiments, the second support 128 may be configured to pivot from a third orientation through a second pivot angle, relative to the first support 122, to a fourth orientation relative to the first support 122, thereby to re-orient the pump frame for installation of one or more connecting rods and associated assemblies (e.g., associated bushings and crossheads), which may include connecting the one or more connecting rods to the crankshaft. In some embodiments, the second pivot angle may range from about 30 degrees to about 60 degrees, from about 35 degrees to about 55 degrees, from about 40 degrees to about 50 degrees, for example, about 45 degrees. In some embodiments, a total of the first pivot angle and the second pivot angle may range from about 100 degrees to about 150 degrees. In some embodiments, the second pivot angle may depend on the architecture of the high-power pump. For example, the second pivot angle may depend on the orientation of the axis along which plungers of a bank of plungers of the high-power pump reciprocate. For example, the second pivot angle may correspond to a pivot angle that results in the axis along which plungers of the bank of plungers reciprocate extending substantially vertically, for example, so that connecting rods may be vertically inserted (e.g., raised or lowered) into corresponding pump frame sections that receive the connecting rod and associated assemblies.


As described herein, the pivoting support assembly 12, in some embodiments, may include one or more first actuators 166 and/or one or more second actuators 176. The one or more first actuators 166 may include, for example, one or more linear actuators, one or more motors, one or more hydraulically powered actuators, one or more a pneumatically powered actuators, and/or one or more an electrically powered actuators. In some embodiments, the one or more first actuators 166 may include one or more self-locking actuators, such as, for example, one or more screw jacks. The one or more second actuators 176 may include, for example, one or more self-locking actuators, such as, for example, one or more screw jacks. In some embodiments, the one or more second actuators 176 may include, for example, one or more linear actuators, one or more motors, one or more hydraulically powered actuators, one or more a pneumatically powered actuators, and/or one or more an electrically powered actuators. Self-locking actuators may prevent extension or retraction of the actuator in the absence of pneumatic, hydraulic, electrical, and/or motor-driven actuation, thereby to prevent movement of the first support 122 or the second support 128 in the event pneumatic, hydraulic, electrical, and/or motor-driven power is lost. In some embodiments, the one or more first actuators 166 and the one or more second actuators 176 may be configured to operate or be activated independently of one another. In some embodiments, the one or more first actuators 166 and the one or more second actuators 176 may be configured to operate or be activated substantially simultaneously and/or substantially concurrently.


In some embodiments, for example, as shown in FIG. 7, the first support 122 may include one or more first attachment features 186 configured to facilitate connection of the pump frame to the first support 122. For example, the first support 122 may include a first support distal cross brace 150, and one or more of the first support proximal cross brace 152 or the first support distal cross brace 150 may include one or more first attachment features 186. For example, in some embodiments, the one or more first attachment features 186 may include one or more of (a) one or more connection apertures configured to receive a fastener to connect the pump frame 76 to the first support 122, or (b) one or more fasteners (e.g., one or more studs) configured to connect the pump frame 76 to the first support 122. In some embodiments, the one or more first attachment features 186 may be positioned on the first support 122, such that the pump frame 76 may be connected to the first support 122 with the longitudinal axis of the pump 11 substantially aligned with the longitudinal axis FS of the first support 122, for example, as shown in FIG. 9A.


In some embodiments, for example, as shown in FIG. 7, the second support 128 may include one or more second attachment features 188 configured to facilitate connection of the pump frame 76 to the second support 128. For example, one or more of the second support side frame members 160 may include one or more second attachment features 188. For example, in some embodiments, the one or more second attachment features 188 may include one or more of (a) one or more connection apertures configured to receive a fastener to connect the pump frame 76 to the second support 128, or (b) one or more fasteners (e.g., one or more studs) configured to connect the pump frame 76 to the second support 122. In some embodiments, the one or more second attachment features 188 may be positioned on the second support 128, such that the pump frame 76 may be connected to the second support 128 with the longitudinal axis of the pump 11 substantially transverse to or perpendicular to the longitudinal axis SS of the second support 128, for example, as shown in FIG. 10A.


In some embodiments, for example, as shown in FIG. 8C, the pivoting support assembly 12 may include one or more first support stops 190 connected to the first support distal cross brace 150 and positioned to abut the base 120 when the first support 122 is in the first orientation. In some embodiments, for example, as shown in FIGS. 8A and 8B, the pivoting support assembly 12 may include one or more second support stop 192 connected to the second support distal end frame member 162 and positioned to abut the first support distal cross brace 150 when the second support 128 is in the third orientation.



FIG. 9A is a schematic perspective side view of an example pump 11 connected to the example first support 122 of the example pivoting support assembly 12 shown in FIG. 7 in an example first orientation, and with the example pump frame 76 in an example first rotational orientation in which the longitudinal axis of the pump frame 76 is substantially aligned with, or substantially parallel to, the longitudinal axis FS of the first support 122, according to embodiments of the disclosure. FIG. 9B is a schematic perspective side view of the pivoting support assembly 12 with the example first support 122 and pump frame 76 shown in FIG. 9A pivoted through an example pivot angle relative to the example base 120 of the pivoting support assembly 12, according to embodiments of the disclosure. FIG. 9C is a schematic perspective side view of the pivoting support assembly 12 with the example first support 122 and pump frame 76 shown in FIG. 9A pivoted through an example pivot angle relative to the example base 120 of the pivoting support assembly 12, and with an example component 194 being inserted into the pump frame 76, according to embodiments of the disclosure. FIG. 9D is a schematic perspective side view of the pivoting support assembly 12 with the example first support 122 and pump frame 76 shown in FIG. 9A pivoted through the example pivot angle shown in FIG. 9C, and with the example component 194 inserted into the pump frame 76, according to embodiments of the disclosure.


As shown in FIGS. 9A-9D, in some embodiments, the pivoting support assembly 12 may be used to at least partially assemble and partially disassemble a pump 11, such as a high-power pump. For example, the example component 194 shown in FIGS. 9C and 9D is a crankshaft (e.g., crankshaft 78, see FIGS. 4A and 4D). Other components and assemblies are contemplated.


As shown in FIGS. 9A-9D, in some embodiments, a method for installing a component 194 in a pump 11 may include attaching a pump frame 76 of the pump 11 to the first support 122 of the pivoting support assembly 12, for example, via one or more of the first attachment features 186 of the first support 122. The method may further include activating one or more of the first actuators 166 connected to the first support 122 and the base 120, which may cause the one or more first actuators 166 to pivot the first support 122 and the pump frame 76 from a first orientation (e.g., substantially horizontal, as shown in FIG. 9A) through a pivot angle to a second orientation (e.g., substantially vertical, as shown in FIGS. 9C and 9D), thereby to re-orient the pump frame 76 for installation of the component 194. In some embodiments, pivoting, via activation of the one or more first actuators 166, the first support 122 and the pump frame 76 from the first orientation to the second orientation may include extending the one or more first actuators 166. In some embodiments, pivoting the first support 122 and the pump frame 76 through the pivot angle to the second orientation may include pivoting the first support 122 and the pump frame 76 through a pivot angle ranging from about 45 degrees to about 100 degrees, for example, about 90 degrees. Thereafter, with the pump frame 76 reoriented, the component 194 may be inserted (e.g., vertically) through the one or more shaft apertures 77 of the pump frame 76 and assembled with the pump frame 76.


In some embodiments, inserting the component 194 into the pump frame 76 may include orienting the component 194, such that a longitudinal axis of the component 194 (e.g., a longitudinal crankshaft axis CR, see FIGS. 4A and 4D) is substantially parallel to a longitudinal pump axis PF of the pump frame 76, and inserting the component 194 through one or more shaft apertures 77 at least partially defined by the pump frame 76. In some embodiments, orienting the component 194 may include orienting the component 194, such that the longitudinal axis of the component 194 is substantially vertical, and inserting the component 194 may include one of (a) lowering the component 194 into the one or more shaft apertures 77 or (b) lifting the component 194 into the one or more shaft apertures 77, for example, via a lifting assembly, such as a crane or fork lift. Although in the example shown the longitudinal axis PF of the pump frame 76 is substantially vertical for assembly of the component 194, other orientations for assembly are contemplated.


Once the component 194 is assembled in the pump frame 76 and any associated procedures are completed, the pump frame 76 and the component 194 may be re-oriented, for example, to the orientation shown in FIG. 9A. For example, the one or more first actuators 166 may be activated to cause the first support 122, the pump frame 76, and the component 194 to pivot from the second orientation, for example, shown in FIGS. 9C and 9D, toward the first orientation, for example, as shown in FIG. 9A, thereby to re-orient the first support 122, the pump frame 76, and the component 194. In some embodiments, pivoting the first support, the pump frame 76, and the component 194 from the second orientation toward the first orientation may include retracting the one or more first actuators 166.



FIG. 10A is a schematic perspective side view of an example pump frame 76 and component 194 (e.g., a crankshaft 78) connected to the example second support 128 of the example pivoting support assembly 12 shown in FIG. 7 in an example first orientation, and with the example pump frame 76 in an example second rotational orientation relative to the example first rotational orientation shown in FIG. 9A, according to embodiments of the disclosure. FIG. 10B is a schematic perspective side view of the pivoting support assembly 12 shown in FIG. 7 with the example first support 122 pivoted through a first pivot angle (e.g., PA1, see FIG. 8B)) relative to the example base 120 and the example second support 128 pivoted through a second pivot angle (e.g., PA2, see FIG. 8B) relative to the example first support 122, according to embodiments of the disclosure. FIG. 10C is a schematic perspective side view of the pivoting support assembly 12 shown in FIG. 7 with the example first support 122 pivoted through a third pivot angle (e.g., PA3, see FIG. 8C) relative to the example base 120 and the example second support 128 pivoted through the fourth pivot angle (e.g., PA4, see FIG. 8C) relative to the example first support 122, and with an example second component 196 being inserted into the pump frame 76, according to embodiments of the disclosure. FIG. 10D is a schematic perspective side view of the pivoting support assembly 12 shown in FIG. 7 with the example first support 122 pivoted through the third pivot angle (e.g., PA3) relative to the example base 120 and the example second support 128 pivoted through the fourth pivot angle (e.g., PA4) relative to the example first support 122, and with the example second component 196 inserted into the pump frame 76, according to embodiments of the disclosure.


As shown in FIGS. 10A-10D, in some embodiments, the pivoting support assembly 12 may be used to at least partially assemble and at least partially disassemble a pump 11, such as a high-power pump. For example, the example second component 196 shown in FIGS. 10C, 10D, and in 11A, 11B, and 11C is a connecting rod-crosshead-bushing assembly 196. Other components and assemblies are contemplated.


As shown in FIGS. 10A-10D, in some embodiments, a method for installing the second component 196 in a pump 11 may include attaching a pump frame 76 of the pump 11 to the second support 122 of the pivoting support assembly 12, for example, via one or more of the second attachment features 188 of the second support 128. As a shown in FIGS. 10A-10D, the pump frame 76 may be attached to the second support such that the longitudinal pump frame axis PF is substantially transverse (e.g., substantially perpendicular) relative to the longitudinal axis B of the base 120, the longitudinal axis FS of the first support 122, and/or the longitudinal axis SS of the second support 128. In some embodiments, the second component 196 (or components) may be installed following installation of the first component 194 (e.g., a crankshaft such as crankshaft 78). For example, the pump frame 76 may be connected to the first support 122, for example, via the one or more first attachments features 186, such that the longitudinal pump frame axis PF is substantially aligned with (e.g., substantially parallel to) the longitudinal axis B of the base 120, the longitudinal axis FS of the first support 122, and/or the longitudinal axis SS of the second support 128, for example, as shown in FIGS. 9A-9D. Thereafter, the first component 194 (e.g., a crankshaft) may be installed in the pump frame 76, for example, as shown in FIGS. 9A-9D. Following installation of the first component 194, the first support 122, the pump frame 76, and the first component 194 may be returned to the orientation shown in FIG. 9A (e.g., a first pump rotational orientation), and the pump frame 76 and first component 194, installed in the pump frame 76, may be disconnected from the first support 122, re-oriented relative to pivoting support assembly 12 (in a second rotational orientation, for example, as shown in FIGS. 10A-10D) relative to the base 120, the first support 122, and/or the second support 128, and connected to the second support 128, for example, via the one or more second attachments features 188, such that the longitudinal pump frame axis PF is substantially transverse (e.g., substantially perpendicular) with respect to the longitudinal axis B of the base 120, the longitudinal axis FS of the first support 122, and/or the longitudinal axis SS of the second support 128, for example, as shown in FIGS. 10A-10D.


As schematically depicted in FIGS. 10A-10D, in some embodiments, the method for installing the second component 196 in the pump 11 may further include activating one or more of the first actuators 166, and pivoting, via activation of the one or more first actuators 166, the first support 122, the second support 128, the pump frame 76, and the first component 194 (e.g., a crankshaft) from the first orientation toward the second orientation, thereby to re-orient the pump frame 76 and the first component 194 relative to the base 120 (see, e.g., FIGS. 10A and 10B). In some embodiments, the method further may include activating one or more second actuators 176 connected to the second support 128 and the first support 122, for example, as described herein, and pivoting, via activation of the one or more second actuators 176, the second support 128, the pump frame 76, and the first component 194 from the second orientation (see, e.g., FIG. 10B) relative to the first support 122 through a second pivot angle to a fourth orientation (see, e.g., FIG. 10C), thereby to re-orient, the second support 128, the pump frame 76, and the first component 194. As shown in FIG. 10C, the pump frame 76 may be oriented, such that the second component 196, which, in some embodiments, may be an assembly of components, may be inserted, while the pump frame 76 and the first component 194 are in the fourth orientation. For example, the second component 196 may be a connecting rod-crosshead-bushing assembly 196, for example, as shown in FIGS. 11A-11C.


In some embodiments, pivoting the first support 122 and pivoting the second support 128 may include pivoting the first support 122 and pivoting the second support 128 about respective pivot axes that are substantially horizontal, and, in some embodiments, re-orienting the pump frame 76 from a first pump rotational orientation to a second pump rotational orientation may include re-orienting the pump frame 76 about a substantially vertical axis. In some embodiments, pivoting the second support 128, the pump frame 76, and the first component (e.g., a crankshaft) may include re-orienting the pump frame 76 from a first roll orientation about a longitudinal pump axis PF of the pump frame 76 (e.g., as shown in FIG. 10A) through a first roll angle to a second roll orientation relative to the first roll orientation (e.g., as shown in FIGS. 10C and 10D).


In some embodiments, as shown in FIGS. 10C and 10D, orienting the second component 196 (e.g., a connecting rod-crosshead-bushing assembly), such that longitudinal axis of the second component 196 (e.g., a connecting rod axis) is substantially perpendicular to a longitudinal axis of the pump frame PF. Inserting the second component 196 into the pump frame 76 may include inserting the second component 196 into a connecting rod receiver 198 at least partially defined by the pump frame 76. For example, in some embodiments, orienting the second component 196 may include orienting the second component, such that the longitudinal axis of the second component 196 is substantially parallel to a longitudinal receiver axis of the connecting rod receiver 198. Inserting the second component 196 into the pump frame 76 may include lowering the second component 196 into the connecting rod receiver 198, for example, as shown in FIGS. 10C and 10D.


In some embodiments, the method also may include connecting the second component 196 to the first component 194 (e.g., connecting a connecting rod to a crankshaft). Once one or more second components 196 have been connected to the first component 194, the method further may include retracting the one or more second actuators 176, and pivoting, via retraction of the one or more second actuators 176, the second support 128, the pump frame 76, the first component 194, and the one or more second components 196 from the fourth orientation toward the third orientation, thereby to re-orient the second support 128, the pump frame 76, the first component 194, and the one or more second components 196, for example, similar to the orientation as shown in FIGS. 10B and 12B. The method further may include retracting the one or more first actuators 166, and pivoting, via retraction of the one or more first actuators 166, the first support 122, the second support 128, the pump frame 76, the first component 194, and the one or more second components 196 from the second orientation toward the first orientation, for example, similar to the orientation as shown in FIGS. 10A and 12D, thereby to re-orient the first support 122, the second support 128, the pump frame 76, the first component 194, and the one or more second components 196.


In some embodiments, the pump frame 76 may include a first bank 200a of first connecting rod receivers 198a positioned to receive a plurality of first connecting rods (or first connecting rod-crosshead-bushing assemblies), and the first bank 200a of first connecting rod receivers 198a may extend substantially parallel to a longitudinal axis of the pump frame PF. As described with respect to some embodiments previously herein, the pump frame 76 further may include a second bank 200b of connecting rod receivers 198b positioned to receive a plurality of second connecting rods (or second connecting rod-crosshead-bushing assemblies), and the second bank 200b of connecting rod receivers 198b may extend substantially parallel to the longitudinal axis of the pump frame PF. In some embodiments, as described herein, the first connecting rods are positioned to reciprocate in a first plane and the second connecting rods are positioned to reciprocate in a second plane forming a bank angle relative to the first plane (see, e.g., FIG. 4D).


In some embodiments, the method of installing the second component 196 into the pump frame 76 further may include inserting, while the pump frame 76 and the first component (e.g., a crankshaft) are in the fourth orientation, one or more additional connecting rods of the first connecting rods into one or more additional connecting rod receivers 198a of the first bank of connecting rod receivers 200a, and connecting the one or more additional connecting rods of the first connecting rods to the first component 194 (e.g., the crankshaft).


In some embodiments, the method may include inserting, while the pump frame 76 and the first component 194 (e.g., a crankshaft) are in the fourth orientation, one or more additional second components 196 (e.g., connecting rods of the first connecting rods) into one or more additional connecting rod receivers of the first bank 200a of connecting rod receivers 198a, and connecting the one or more additional second components 196 (e.g., the one or more additional connecting rods of the first connecting rods) to the first component 194 (e.g., the crankshaft).


In some embodiments, the method may include, following pivoting the second support 128, the pump frame 76, the first component 194, and the one or more second components 196 (one or more connecting rods of the first connecting rods) from the fourth orientation toward the first orientation, re-orienting the pump frame 76 from the second pump rotational orientation (see, e.g., FIGS. 10A-10D), wherein the first bank 200a of connecting rod receivers 198a is in a first position relative to the second support 128, to a third pump rotational orientation, such that the second bank 200b of connecting rod receivers 198b is in the first position relative to the second support 128. For example, the third pump rotational orientation is the opposite of the second pump rotational orientation shown in FIG. 10A, for example, such that the second bank 200b of connecting rod receivers 198b is in the location of the first bank 200a of connecting rod receivers 200a shown in FIG. 10A. Following re-orientation to the third pump rotational orientation, the method may include attaching the pump frame 76 to the second support 128 of the pivoting support assembly 12, and the method schematically depicted in FIGS. 10A-10D may be substantially repeated, so that additional second components 196 (e.g., additional connecting rod assemblies) may be inserted into the connecting rod receivers 198b of the second bank 200b of connecting rod receivers 198b, and the additional second components 196 may be connected to the first component 194 (e.g., a crankshaft).


For example, the method further may include activating the one or more first actuators 166, and pivoting, via activation of the one or more first actuators, the first support 122, the second support 128, the pump frame 76, the first component 194 (e.g., crankshaft), and the one or more second components 196 (e.g., first connecting rods) from the first orientation toward the second orientation, thereby to re-orient the pump frame 76, the first component 194, and the one or more second components 196. The method also may include activating the one or more second actuators 176 connected to the second support 128 and the first support 122, and pivoting, via activation of the one or more second actuators 176, the second support 128, the pump frame 76, the first component 194 (e.g., a crankshaft), and the one or more second components (e.g., one or more first connecting rods) from the third orientation relative to the first support 122 through the second pivot angle to the fourth orientation, thereby to re-orient the pump frame 76, the first component 194, and the one or more second components 196. The method in some embodiments, further may include inserting, while the pump frame 76, the first component 194, and the one or more second components 196 (e.g., the one or more first connecting rod) are in the fourth orientation, one or more third components (e.g., a first one of a second plurality of connecting rods) into one or more corresponding connecting rod receivers of the second bank 200b of connecting rod receivers 198b. The method also may include connecting the one or more third components (e.g., the one or more connecting rods of the second connecting rods) to the first component 194 (e.g., the crankshaft). Thereafter, in some embodiments, the method further may include retracting the one or more second actuators 176, and pivoting, via retraction of the one or more second actuators 176, the second support 128, the pump frame 76, the first component 194 (e.g., the crankshaft), the one or more second components 196 (e.g., connecting rods of the first bank 200a), and the one or more third components (e.g., connecting rods of the second bank 200b) from the fourth orientation toward the first orientation, thereby to re-orient the first support 122, the second support 128, the pump frame 76, the first component 194 (e.g., the crankshaft)), the one or more second components 196 (e.g., connecting rods of the first bank 200a), and the one or more third components (e.g., connecting rods of the second bank 200b).



FIG. 11A is a schematic perspective side view of an example connecting rod-crosshead-bushing assembly 196, according to embodiments of the disclosure. FIG. 11B is a schematic side view of the example connecting rod-crosshead-bushing assembly 196 shown in FIG. 11A, and FIG. 11C is a schematic side section view of the example connecting rod-crosshead-bushing assembly 196 shown in FIG. 11A, according to embodiments of the disclosure.


As shown in FIGS. 11A-11C, in some embodiments, the connecting rod-crosshead-bushing assembly 196 may enhance assembly, disassembly, and/or maintenance of a pump, such as, for example, the high-power pumps 11 described herein. In some embodiments, the connecting rod-crosshead-bushing assembly 196 may include a bushing 202 having a crankshaft end 204 and a bushing distal end 206. The bushing 202 may at least partially define a bushing interior 208 extending between the crankshaft end 204 and the bushing distal end 206, and the bushing interior 208 may have a substantially cylindrical interior surface 210 at least partially defining a bushing lip 212 extending radially inward adjacent the bushing distal end 206 and at least partially defining an inner radial dimension. The connecting rod-crosshead-bushing assembly 196 also may include a connecting rod 214 having rod body 216 including a rod body proximal end 218 positioned to be connected to a crankshaft and a rod body crosshead end 220 opposite the rod body proximal end 218. The rod body 216 may be at least partially received in the bushing interior 208, for example, as shown. In some embodiments, the connecting rod 214 may substantially correspond to embodiments of the connecting rod 94 described herein. The connecting rod-crosshead-bushing assembly 196 further may include a crosshead 222 connected to the rod body crosshead end 220 and may be positioned to reciprocate within the bushing interior 208. In some embodiments, the crosshead 222 may be connected to a corresponding plunger, such as, for example, one of the plungers 84 and/or 88 described herein. In some embodiments, a respective crosshead 222 may be connected to a plunger, for example, via pony rod. In some embodiments, the crosshead 222 may include a crosshead body 224 having a crosshead proximal end 226 and extending from the crosshead proximal end 226 to a crosshead distal end 228. The crosshead body 224 may at least partially define an exterior radial dimension greater than the inner radial dimension of the bushing lip 212. In some embodiments, the connecting rod-crosshead-bushing assembly 196 also may include an attachment boss 230 connected to the crosshead distal end 228 and positioned to be connected to lift hardware 232, thereby to support the connecting rod-crosshead-bushing assembly 196 via the lift hardware 232. The lift hardware 232 may include a lifting hook or lifting eye, or any other similar component that may be used to lift or support the connecting rod-crosshead-bushing assembly 196. The attachment boss 230, in some embodiments, may facilitate assembly of the connecting rod-crosshead-bushing assembly 196 into the pump frame 76, for example, as described herein with respect to FIGS. 10A-10D. In some embodiments, the bushing lip 212 may serve to support the bushing 202 via the crosshead 222, for example, when the connecting rod-crosshead-bushing assembly 196 is lifted and/or lowered into position relative the pump frame 76 and/or crankshaft 78 during assembly, for example, using the lift hardware 232.


In some embodiments, once the connecting rod-crosshead-bushing assembly 196 is assembled to the crankshaft 78, the lift hardware 232 may be separated from the connecting rod-crosshead-bushing assembly 196 (e.g., from the attachment boss 230), and a plunger may be connected to the crosshead 222 of the corresponding connecting rod-crosshead-bushing assembly 196. For example, the crosshead 222 may be connected to a corresponding plunger via the attachment boss 230 and an intermediate connector, such as, for example, a corresponding pony rod connected to the attachment boss 230 of the crosshead 222 and the plunger.


Some embodiments of the connecting rod-crosshead-bushing assembly 196 may include a rod pin 234 connecting the rod body crosshead end 220 of the connecting rod 214 and the crosshead 222 to one another, for example, as shown in FIGS. 11A-11C. In some embodiments, the attachment boss 230 may include a cylindrical extension 236 at least partially defining boss threads 238 positioned to engage complimentary threads 240 of the lift hardware 232. In some embodiments, the boss threads 238 are internal threads configured to engage with external threads of the crosshead 222, and in some embodiments, the boss threads 238 are external threads configured to engage with internal threads of the crosshead 222.


As shown in FIGS. 11A-11C, in some embodiments, the crosshead body 224 may at least partially define an interior rod pocket 242, and the crosshead end 220 of the connecting rod may be at least partially received in the interior rod pocket 242. The crosshead body 224 may at least partially define a lubricant passage 244 extending from an exterior surface of the crosshead body 224 to the interior rod pocket 242. In some embodiments, one or more of the exterior surface of the crosshead 222 or the bushing interior 208 may at least partially define a clearance 246 between the exterior surface of the crosshead 222 and the bushing interior 208, and the clearance 246 may be in fluid communication with the lubricant passage 244, thereby to provide lubricant to the lubricant passage 244.


In some embodiments, the bushing 202 may be provided with one or more bushing apertures 248, for example, as shown in FIGS. 11A and 11B. The one or more bushing apertures 248 may reduce the weight of the connecting rod-crosshead-bushing assembly 196 and/or may provide a lubricant relief (or reliefs) to reduce the likelihood of, or prevent, dashpot effects, for example, as the crosshead 222 reciprocates within the bushing 202.


During assembly to the crankshaft 78, in some embodiments, once the connecting rod-crosshead-bushing assembly 196 has been positioned, for example, such that the rod body proximal end 218 engages a crankpin 92 of the crankshaft 78 (FIGS. 4B and 4C) (e.g., once the connecting rod-crosshead-bushing assembly 196 has been lowered into position), a crankpin end connector 250 (FIG. 11A) may be connected to the rod body proximal end 218 of the connecting rod 214, thereby to secure the connecting rod 214 to the crankpin of the crankshaft 78. An at least similar procedure may be repeated to connect multiple connecting rod-crosshead-bushing assemblies 196 to corresponding crankpins 92 of the crankshaft 78.



FIG. 12A is a schematic perspective side view of the pivoting support assembly 12 shown in the orientation of FIGS. 10C and 10D, with four example connecting rod-crosshead-bushing assemblies 196 (e.g., 196a, 196b, 196c, and 196d) inserted into the pump frame 11, according to embodiments of the disclosure, and FIG. 12B is a schematic perspective side view of the pivoting support assembly 12 shown in the orientation of FIG. 10B, with the four example connecting rod-crosshead-bushing assemblies 196a, 196b, 196c, and 196d inserted into the pump frame 76, according to embodiments of the disclosure. FIG. 12C is a schematic side view of the pivoting support assembly 12 shown in FIG. 7, with the example second support 128 pivoted through an example pivot angle relative to the example base 120 and the example first support 122, according to embodiments of the disclosure. FIG. 12D is a schematic perspective end view of the example pivoting support assembly 12 and pump frame 76 shown in the orientations shown in FIG. 12C, according to embodiments of the disclosure. As shown in FIGS. 12A-12D, once the connecting rod-crosshead-bushing assemblies 196 (e.g., 196a, 196b, 196c, and 196d) have been connected to the corresponding crankpins 92 of the crankshaft 78, the second support 128 and the first support 122 may be pivoted back to the first orientation (e.g., as shown in FIGS. 7, 9A, and 10A). In some embodiments of the pump 11, for example, as shown in FIGS. 2, 3B, 4A-4D, and 6, the pump frame 11 may be re-oriented from the second rotational orientation shown in FIG. 10A to a third rotational orientation in which the pump frame 76 is positioned on the pivoting support assembly 12 and the second support 128 opposite to the orientation shown in FIG. 10A. This may facilitate the assembly of a second plurality of the connecting rod-crosshead-bushing assemblies 196 in the second bank 200b of the pump frame 76, for example, as described herein.



FIG. 13A, FIG. 13B, FIG. 13C, FIG. 13D, and FIG. 13E are a block diagram of an example method 1300 for installing components in a pump, such as, for example, a power end of a high-power pump, such as the high-power pumps described herein, as well as others. The example method 1300 is illustrated as a collection of blocks in a logical flow graph, which represent a sequence of operations. In some embodiments of the method 1300, one or more of the blocks may be manually and/or automatically executed. In the context of software, where applicable, the blocks may represent computer-executable instructions stored on one or more computer-readable storage media that, when executed by one or more processors, perform the recited operations. Generally, computer-executable instructions include routines, programs, objects, components, data structures, and the like that perform particular functions or implement particular data types. The order in which the operations are described is not intended to be construed as a limitation, and any number of the described blocks can be combined in any order and/or in parallel to implement the method.


As shown in FIGS. 13A-13E, an example method 1300 for installing components in a pump may include, at 1302 (see FIG. 13A), attaching a pump frame of the pump to a first support of a pivoting support assembly, for example, as described herein.


At 1304, the example method 1300 may include activating one or more first actuators connected to the first support and a base of the pivoting support assembly, for example, as described herein.


The example method 1300, at 1306, may include pivoting, via activation of the one or more first actuators, the first support and the pump frame from a first orientation through a first pivot angle to a second orientation, thereby to re-orient the pump frame, for example, as described herein.


At 1308, the example method 130 may include determining whether the first support and/or the pump frame have pivoted to the second orientation. In some embodiments, one or more sensors may be provided and positioned to generate one or more pivot sensor signals indicative of the orientation of the pump frame and/or the first support, such as, for example, rotary sensors and/or limit sensors.


If, at 1308, it is determined that the pump frame and/or the first support have not pivoted to the second orientation, at 1310, the example method 1300 may include continuing to pivot the pump frame and the first support and thereafter returning to 1308 to determine whether the pump frame and/or the first support have pivoted to the second orientation, for example, as described herein.


If, at 1308, it is determined that the pump frame and/or the first support have pivoted to the second orientation, the example method 1300, at 1312, may include inserting, while the first support and/or the pump frame are in the second orientation, a crankshaft of the pump into the pump frame, for example, as described herein. In some embodiments, this may include substantially aligning the crankshaft axis of the crankshaft with a longitudinal axis at least partially defined by the crankshaft apertures at least partially defined by one or more frame sections of the pump frame. In some embodiments, this may include orienting the crankshaft, such that the crankshaft axis of the crankshaft is substantially vertical and dropping (or raising) the crankshaft into the crankshaft apertures until it is properly positioned relative to the pump frame, for example, as described herein.


At 1314, the example method 1300 may include retracting the one or more first actuators, for example, as described herein.


The example method 1300, at 1316, may include pivoting, via retraction of the one or more first actuators, the first support and the pump frame from the second orientation toward the first orientation, thereby to re-orient the first support, the pump frame, and the crankshaft, for example, as described herein.


At 1318 (see FIG. 13B), the example method 1300 may include determining whether the first support and/or the pump frame have pivoted back to the first orientation. In some embodiments, one or more sensors may be provided and positioned to generate one or more pivot sensor signals indicative of the orientation of the pump frame and/or the first support, such as, for example, rotary sensors and/or limit sensors.


If, at 1318, it is determined that the pump frame and/or the first support have not pivoted back to the first orientation, at 1320, the example method 1300 may include continuing to pivot the pump frame and the first support and thereafter returning to 1318 to determine whether the pump frame and/or the first support have pivoted back to the first orientation.


If, at 1318, it is determined that the pump frame and/or the first support have pivoted back to the first orientation, at 1322, the example method 1300 may include re-orienting the pump frame and the crankshaft from a first pump rotational orientation to a second pump rotational orientation transverse relative to the first pump rotational orientation. In some embodiments, this may include disconnecting the pump frame from the first support and re-orienting the pump frame from a first pump rotational orientation 90 degrees relative to the pivoting support assembly, for example, such the longitudinal axis of the pump frame is substantially transverse (e.g., substantially perpendicular) with respect to the pivoting support assembly in the second pump rotational orientation, for example, as described herein. In some embodiments, re-orienting the pump frame may include lifting, for example, via a crane or lifting machine, the pump frame and the crankshaft to separate them from the first support and spinning the pump frame and the crankshaft through 90 degrees (or 270 degrees) in a substantially horizontal plane, for example, as described herein.


At 1324, the example method 1300 may include attaching the pump frame to a second support of the pivoting support assembly in the second pump rotational orientation, for example, as described herein.


The example method 1300, at 1326, may include activating the one or more of the first actuators, for example, as described herein.


At 1328, the example method 1300 may include pivoting, via activation of the one or more first actuators, the first support, the second support, the pump frame, and the crankshaft from the first orientation toward the second orientation, thereby to re-orient the pump frame and the crankshaft, for example, as described herein.


The example method 1300, at 1330, may include activating one or more second actuators connected to the second support and the first support, for example, as described herein.


At 1332 (see FIG. 13C), the example method 1300 may include pivoting, via activation of the one or more second actuators, the second support, the pump frame, and the crankshaft from a third orientation relative to the first support through a second pivot angle to a fourth orientation, thereby to re-orient the pump frame and the crankshaft, for example, as described herein.
