Patent Application
20180251952
The present disclosure generally pertains to an auger attachment system, and is more particularly directed to an auger attachment system for an extendable boom machine.
Augers mounted on boom equipment or machines may be used in a variety of construction, mining, and other industrial applications. In some related art boom mounted auger systems, the auger may be mounted on the butt or stationary stage of the boom to allow the boom to be extended or retracted for picking or lifting operations without removing the auger. However, in this position, the entire machine would need to be moved laterally as the auger drills downward to maintain the auger in a vertical or plumb position due to the fixed length of the butt stage. In other related art boom mounted auger systems, the auger may be mounted on the second or moving stage of boom. However, in this position, the second stage could not be used for any lifting or picking operations until the auger is removed, which could be a complex process due to the weight of the auger and torque generated during operation of the auger.
Aspects of the present application may relate to an auger attachment system for an extendable boom having a first stage, and a second stage. The auger attachment system may include a fixed mounting configured to couple to an auger, the fixed mounting being coupled to the second stage of the extendable boom; an extendable mounting, configured to couple to the auger, the extendable mounting being coupled to the first stage of the extendable boom, and a linear actuator configured to extend and retract the extendable mounting to transfer the auger from the extendable mounting to the fixed mounting.
Additional aspects of the present application may relate to include an auger system for an extendable boom having a first stage, and a second stage. The auger system may include a hydraulic auger and an auger attachment system. The auger attachment system may include a fixed mounting configured to couple to the auger, the fixed mounting being coupled to the second stage of the extendable boom, an extendable mounting, configured to couple to the auger, the extendable mounting being coupled to the first stage of the extendable boom, and a linear actuator configured to extend and retract the extendable mounting to transfer the auger from the extendable mounting to the fixed mounting.
Further aspects of the present application may relate to a boom machine including an extendable boom, a hydraulic auger, and an attachment system. The extendable boom may include a first stage and a second stage. The auger attachment system includes a fixed mounting configured to couple to the auger, the fixed mounting being coupled to the second stage of the extendable boom; an extendable mounting, configured to couple to the auger, the extendable mounting being coupled to the first stage of the extendable boom, and a linear actuator configured to extend and retract the extendable mounting to transfer the auger from the extendable mounting to the fixed mounting.
The following detailed description provides further details of the figures and example implementations of the present application. Reference numerals and descriptions of redundant elements between figures are omitted for clarity. Terms used throughout the description are provided as examples and are not intended to be limiting. For example, the use of the term “automatic” may involve fully automatic or semi-automatic implementations involving user or operator control over certain aspects of the implementation, depending on the desired implementation of one of ordinary skill in the art practicing implementations of the present application.
In some example implementations, an auger attachment system that allows attachment of the auger to either the butt stage or second stage of a boom machine, and transition therebetween may be provided. For example, the auger attachment system may provide a fixed mounting on the second stage boom and an extendable mounting on the butt stage of the boom, both mountings being configured to hold the auger. Further, in some example implementations, the auger attachment system may also include an actuator configured to extend and retract the extendable mounting to transfer to auger from the extendable mounting to the fixed mounting.
The boom machine 100 may include a machine body 110, one or more hydraulic systems 115, one or more engaging implements 120, and an undercarriage structure 125. The machine body 110 may optionally include a cab 130 to house a machine operator. An electronic control system 135 can be housed in the cab 130 that can be adapted to allow a machine operator to manipulate and articulate the engaging implements 120 for any suitable application and provide performance readouts to the operator. As discussed below, the electronic control system 135 may include a computing device such as computing device 805 of
Though a cab 130 to house an operator is illustrated on the machine body 110, example implementations of the present application are not required to have a cab or be directly operated by an operator on the boom machine 100. For example, some example implementations of the present application may be remotely operated by an operator not directly riding the boom machine 100. The remote operator may be in the same general area as the boom machine 100 or may be located a large distance away. In some embodiments, the electric control system 135 may allow control of the boom machine 100 via radio frequency communication, cellular communication, wired communication, or any other type of remote control that might be apparent to a person of ordinary skill in the art.
The hydraulic system 115 may connect at one end to the machine body 110 and may support the engaging implement 120 at an opposing, distal end. As illustrated, the engaging implement 120 may be a lifting boom 140 with a lift attaching system 142 having a lifting attachment implement 144 mounted on a tension line 146. The tension line 146 is around a winch system 148 mounted behind the cab 130. The lifting boom 140 may be an extendable boom having a butt or stationary stage 176 and a second or extendable stage 178. The extension and retract of the second stage 178 relative to the butt stage 176 may be performed hydraulically and controlled by the electronic control system 135. Example implementations are not limited to this configuration, and the extension/retraction of the second stage 178 may be controlled by any mechanism that may be apparent to a person of ordinary skill in the art.
Additionally, the engaging implement 120 may also include an auger attachment system 174 to allow attachment of an auger device to either the butt stage 176 or the second stage 178. The auger attachment system 174 is discussed in greater detail with respect to
The engaging implement 120 is not limited to a lifting boom 140 and may be any type of engaging implement 120 that might be apparent to a person of ordinary skill in the art include a bucket boom for lifting an operator, a backhoe implement, or any other implement that might be apparent to a person of ordinary skill in the art.
The undercarriage structure 125 may include a support structure 150 and the undercarriage track system 105. The support structure 150 may connect the undercarriage track system 105 to the machine body 110 and may support the undercarriage track system 105.
The undercarriage track system 105 may include a track roller frame assembly 152 and an associated track chain assembly 154 on each side of the undercarriage structure 125. It will be appreciated that only one track roller frame assembly 152 and only one track chain assembly 154 is visible in
The boom machine 100 may also include a power source 156 mounted on the machine body 110 behind the cab 130 (in
Each track roller frame assembly 152 may include one or more idler wheels 158, a drive sprocket wheel 160, and track roller assemblies 162. In the embodiment illustrated, an idler wheel 158 is coupled to the support structure 150 at one end, and the drive sprocket wheel 160 is coupled to the support structure 150 at an opposite end. In other embodiments, a pair of idler wheels 158 may be coupled to the support structure 150 and the drive sprocket wheel 160 may be adjacent to one of the idler wheels 158.
The drive sprocket wheel 160 may be powered in forward and reverse directions by the power source 156 of the boom machine 100. In some embodiments, the drive sprocket wheel 160 may be coupled to the engine of the boom machine 100 by a final drive. The drive sprocket wheel 160 drives the track chain assembly 154 to move the boom machine 100.
Track roller assemblies 162 may be positioned between the ends of the support structure 150 and at least partially below the support structure 150. In the embodiment illustrated, the track roller assemblies 162 are positioned between the idler wheel 158 and the drive sprocket wheel 160. In other embodiments, the track roller assemblies 162 are positioned between a pair of idler wheels 158. The track roller assemblies 162 may include a front roller assembly 164 may be positioned adjacent the idler wheel 158 at the front end of the support structure 150 and a rear roller assembly 166 may be positioned adjacent the drive sprocket wheel 160 at the rear end of the support structure 150. Idler wheels 158 and track roller assemblies 162/164/166 may be configured to guide the track chain assembly 154 around the support structure 150.
In embodiments, each track chain assembly 154 may include track links (not numbered) inter-connected and linked together to form a closed chain. In the embodiment illustrated, track links are connected to, such as by fastening, ground engaging shoes 168. The ground engaging shoes 168 or ground engaging portions may be configured to overlap. In other embodiments, each track chain assembly 154 includes track pads inter-connected and linked together. The track pads may include a track link and a ground engaging shoe that are cast or forged as an integral unit.
As illustrated, the machine body 110 may be connected to the support structure 150 by a rotating mechanism 170. Further, the support structure 150 may connect two track roller frame assemblies 152 of the undercarriage track system 105 to form a support base for the machine body 110. In some example implementations, the rotating mechanism 170 may be a hydraulic rotary actuator that allows the machine body 110 to rotate relative to the undercarriage track system 105. However, the rotating mechanism 170 is not limited to this configuration and may be any mechanism that allows relative rotation between the support structure 150 and the machine body 110.
In
The extendable mounting 204 may include a fixed block 206, a linear actuator 208 and a sled 210. The fixed block 206 is attached to the butt stage 176 in a fixed manner to provide a stationary base for the linear actuator 208 to push against. The attachment mechanism between the butt stage 176 and the fixed block 206 is not particularly limited and may include welding, bolting, press fitting or any other connection mechanism that might be apparent to a person of ordinary skill in the art. Additionally, the fixed block 206 may also be formed as unitary piece of the butt stage 176 (e.g., an extension or protrusion formed as part of a housing of the butt stage 176).
The linear actuator 208 is illustrated as a mechanical actuator having a screw member 212 inserted into one end of a rotary housing 214 attached to the sled 210. The rotary housing 214 may have a handle 216 that may be configured to be used to rotate the rotary housing 214. By rotating the rotary housing 214 relative to the screw member 212, a linear force may be generated to move the sled 210 toward and away from the fixed mounting 202 mounted on the second stage 178.
Though the linear actuator 208 is illustrated as a mechanical actuator in
The sled 210 includes a mounting body 218 slidingly attached to a sliding support member 220 attached to the butt stage 176. The attachment mechanism between the butt stage 176 and the sliding support member 220 is not particularly limited and may include welding, bolting, press fitting or any other connection mechanism that might be apparent to a person of ordinary skill in the art. Additionally, the sliding support member 220 may also be formed as unitary piece of the butt stage 176 (e.g., an extension or protrusion formed as part of a housing of the butt stage 176). The mounting body 218 may have a mounting bracket 222 at one end that is configured to engage an attaching bracket 224 connected to an auger 226. As illustrated, the mounting bracket 222 may have a protrusion 228 extending laterally outward. The mounting bracket 222 may also include a pin hole 230 that extends through the mounting bracket 222. In some example implementations, a retaining pin 232 may be removably inserted through the pin hole 230. Further, in some example implementations, a sensor may detect when the auger is present in the sled and a sensor to detect when the auger is fully retracted and contacting stoppers (e.g., in a stowage position).
The fixed mounting 202 may include an auger support arm 234 having an auger support groove 236 configured to support the attaching bracket 224 of the auger 226. As illustrated in
In the first configuration of
Further, the attaching bracket 224 may also include a support protrusion 248 configured to be inserted into the auger support groove 236 when the auger 226 is mounted on the fixed mounting 204. In some example implementations, the auger support hole 240 with a support hole 250 formed through the support protrusion 248 of the attaching bracket 224 of the auger 226. The holding pin 242 may be inserted through the support hole 250 extending through the attaching bracket 224. Again, in some example implementations, the support protrusion 248 may rest in the auger support groove 236 such that auger support groove 236 holds the entire weight of the auger 226 such that the holding pin 242 can be inserted and removed without any required tools.
The attaching bracket 224 may also include a pivot 252 to allow lateral movement of the auger 226 to allow greater freedom of positioning the auger 226.
As discussed above, the holding pin 242 is still inserted through the auger support holes 240 of the lateral support plates 238 and the attaching bracket 224 of the auger 226. In this configuration, if the second stage 178 is moved relative to the butt stage 176 of the boom 140, serious damage could be done to the auger attachment system 174. In some example implementations, the attachment of the auger 226 to the extendable mounting 204, the position of the linear actuator, or the presents of the auger in the stowage position may be detected by sensors placed in various locations, and based on the sensor readings and other crane configuration information, the electronic control system 135 may lock-off extension of the boom 140 or the activation of the auger drive.

Output device/interface 840 may include a display, television, monitor, printer, speaker, braille, or the like. In some example implementations, input/user interface 835 and output device/interface 840 can be embedded with or physically coupled to the computing device 805. In other example implementations, other computing devices may function as or provide the functions of input/user interface 835 and output device/interface 840 for a computing device 805.
Examples of computing device 805 may include, but are not limited to, highly mobile devices (e.g., smartphones, devices in vehicles and other machines, devices carried by humans and animals, and the like), mobile devices (e.g., tablets, notebooks, laptops, personal computers, portable televisions, radios, and the like), and devices not designed for mobility (e.g., desktop computers, server devices, other computers, information kiosks, televisions with one or more processors embedded therein and/or coupled thereto, radios, and the like).
Computing device 805 can be communicatively coupled (e.g., via I/O interface 825) to external storage 845 and network 850 for communicating with any number of networked components, devices, and systems, including one or more computing devices of the same or different configuration. Computing device 805 or any connected computing device can be functioning as, providing services of, or referred to as a server, client, thin server, general machine, special-purpose machine, or another label.
I/O interface 825 can include, but is not limited to, wired and/or wireless interfaces using any communication or I/O protocols or standards (e.g., Ethernet, 802.11x, Universal System Bus, WiMAX, modem, a cellular network protocol, and the like) for communicating information to and/or from at least all the connected components, devices, and network in computing environment 800. Network 850 can be any network or combination of networks (e.g., the Internet, local area network, wide area network, a telephonic network, a cellular network, satellite network, and the like).

Computing device 805 can be used to implement techniques, methods, applications, processes, or computer-executable instructions in some example computing environments. Computer-executable instructions can be retrieved from transitory media, and stored on and retrieved from non-transitory media. The executable instructions can originate from one or more of any programming, scripting, and machine languages (e.g., C, C++, C#, Java, Visual Basic, Python, Perl, JavaScript, and others).
Processor(s) 810 can execute under any operating system (OS) (not shown), in a native or virtual environment. One or more applications can be deployed that include logic unit 855, application programming interface (API) unit 860, input unit 865, output unit 870, auger present in sled sensing unit 875, auger present in stowage position sensing unit 880, boom extension controlling unit 885, linear actuator sensing unit 890, auger drive controlling unit 892 and inter-unit communication mechanism 895 for the different units to communicate with each other, with the OS, and with other applications (not shown). For example, auger present in sled sensing unit 875, auger present in stowage position sensing unit 880, boom extension controlling unit 885, linear actuator sensing unit 890, and auger drive controlling unit 892, may implement one or more processes to sense the position of the auger as well as control the extension of a boom, activation of the auger drive and detect extension of a linear actuator of an actuator attaching system. The described units and elements can be varied in design, function, configuration, or implementation and are not limited to the descriptions provided.
In some example implementations, when information or an execution instruction is received by API unit 860, it may be communicated to one or more other units (e.g., logic unit 855, input unit 865, output unit 870, auger present in sled sensing unit 875, auger present in stowage position sensing unit 880, boom extension controlling unit 885, linear actuator sensing unit 890, and auger drive controlling unit 892). For example, the auger present in sled sensing unit 875 may detect the presence of the auger in the sled. Similarly, the auger present in stowage position sensing unit 880 may detect the presence of the auger in the stowage position. Based on the detection of the auger position, the boom extension controlling unit 885 may lock or block extension of a boom (e.g., prevent the relative movement of a second stage relative to butt stage of a boom) or the auger controlling unit 892 may block activation of the auger drive. Additionally, the linear actuator sensing unit 890 may detect the extension of placement of an auger attachment system and based on the detected placement control the boom extension controlling unit 885 or auger drive controlling unit 892.
In some instances, the logic unit 855 may be configured to control the information flow among the units and direct the services provided by API unit 860, input unit 865, output unit 870, auger present in sled sensing unit 875, auger present in stowage position sensing unit 880, boom extension controlling unit 885, linear actuator sensing unit 890, and auger drive controlling unit 892 in some example implementations described above. For example, the flow of one or more processes or implementations may be controlled by logic unit 855 alone or in conjunction with API unit 860.
The foregoing detailed description has set forth various example implementations of the devices and/or processes via the use of block diagrams, schematics, and examples. Insofar as such block diagrams, schematics, and examples contain one or more functions and/or operations, each function and/or operation within such block diagrams, flowcharts, or examples can be implemented, individually and/or collectively, by a wide range of hardware.
While certain example implementations have been described, these example implementations have been presented by way of example only, and are not intended to limit the scope of the protection. Indeed, the novel apparatuses described herein may be embodied in a variety of other forms. Furthermore, various omissions, substitutions and changes in the form of the systems described herein may be made without departing from the spirit of the protection. The accompanying claims and their equivalents are intended to cover such forms or modifications as would fall within the scope and spirit of the protection.
