Patent Application
20140165355
Large-scale furnace/oven systems often comprise one or more accesses used to access the interior of the system, such as for maintenance, charging, unloading, etc. An access typically comprises an access panel, such as a door, which may be opened to utilize the access and properly closed to seal the access. Occasionally, the panel door may be repaired and/or replaced, necessitating removal of the door from the furnace/oven. As one example, a coke oven can comprise a plurality of large oven access doors (e.g., each weighing 12,000 pounds), which may provide a challenge when attempting to remove them from the oven.
This Summary is provided to introduce a selection of concepts in a simplified form that are further described below in the Detailed Description. This Summary is not intended to identify key factors or essential features of the claimed subject matter, nor is it intended to be used to limit the scope of the claimed subject matter.
As provided herein, a jig manipulator may be devised that facilitates removal of a large component, such as an oven door from a furnace/oven, such as by a crane. That is, for example, the jig manipulator may be engaged with the crane at a first end of the manipulator, and may be engaged with a component handling jig at a second end of the manipulator. In this example, a combination of the crane, the jig manipulator, and the jig attached to the manipulator can be used to manipulate, remove and/or replace the component, such as removal of an oven door on a furnace or oven.
In one implementation, the jig manipulator may comprise a first end and a second end. Further, the jig manipulator can comprise a crane engagement means, which is configured to engage with a crane such that the jig manipulator is structurally supported by the crane. Further, the jig manipulator may comprise a jig engagement means, which is configured to engage a component handling jig such that the jig manipulator engaged with the component handling jig can support a heavy component during its manipulation, removal and/or replacement.
To the accomplishment of the foregoing and related ends, the following description and annexed drawings set forth certain illustrative aspects and implementations. These are indicative of but a few of the various ways in which one or more aspects may be employed. Other aspects, advantages and novel features of the disclosure will become apparent from the following detailed description when considered in conjunction with the annexed drawings.
What is disclosed herein may take physical form in certain parts and arrangement of parts, and will be described in detail in this specification and illustrated in the accompanying drawings which form a part hereof and wherein:
The claimed subject matter is now described with reference to the drawings, wherein like reference numerals are generally used to refer to like elements throughout. In the following description, for purposes of explanation, numerous specific details are set forth in order to provide a thorough understanding of the claimed subject matter. It may be evident, however, that the claimed subject matter may be practiced without these specific details. In other instances, structures and devices may be shown in block diagram form in order to facilitate describing the claimed subject matter.
In one aspect, a facility that utilizes large industrial systems, such as large ovens (e.g., and/or furnaces), may periodically manipulate components of the industrial systems, such as for maintenance, removal and/or replacement. As an example, large access panels (“doors”) on furnace of ovens may be removed for maintenance and/or replacement. As one example, in a coke (e.g., for steel) processing facility large coke ovens are used to process the coke at very high temperatures. Often, the coke ovens run in a long series and comprise a plurality of access panels that may be used for oven maintenance, charging, cleaning, product removal, etc., for example. In this example, the access panel doors can be lined with refractory ceramic material that may lose effectiveness over time, and may need to be replaced. In order to replace the refractory material, the access door is typically removed, where an oven doors can be up to twelve feet wide (e.g., or greater), and weigh up to approximately 12,000 pounds (e.g., or greater). A large door removal jig is commonly utilized to facilitate door removal, for example.
A jig manipulator may be devised to facilitate manipulation (e.g., removal) of a large industrial component, for example, where the jig manipulator can be attached to a component manipulation jig and engaged with an extension crane (e.g., a hydraulic crane). In this way, for example, the component manipulation jig can be manipulated safely, using the crane engaged with the jig manipulator, such that the component (e.g., oven door) may be effectively removed and/or replaced in a more efficient manner (e.g., than prior door removal techniques).
In one implementation, the jig manipulator comprises a crane engagement means 102, at a first end, where the crane engagement means 102 is configured to engage with at least a portion of a crane 154 such that the jig manipulator 100 is structurally supported by the crane, for example. For example, the crane engagement means 102 may be selectively coupled with a boom of a hydraulic crane. The jig manipulator 100 can further comprise a jig engagement means 105, at a second end, where the jig engagement means 105 is configured to engage a component handling jig. For example, the component handling jig may comprise a door handling jig that can engage, support, and manipulate a door (e.g., coke oven door) using a combination of the crane, jig manipulator and component handling jig, during removal and/or replacement of the door from the oven.
The jig manipulator may be further described with reference to the example implementations of
In the example implementations of
In this example implementation, the vertical rotatable engagement formed between the vertical rotation handler 104 and the structural support component 110 may comprise a vertical rotatable axis 106 for the jig manipulator 100, for example, where a door handling jig (not shown) engaged with the vertical rotation handler 104 may be manipulated in vertical rotation (e.g., yaw, comprising movement from side to side) with respect to a face of a target door (e.g., intended for engagement with the door handling jig). In one implementation, the vertical rotatable axis 106 can provide a lateral range of motion (rotationally) to the vertical rotation handler 104 and attached door handling jig (not shown), where the lateral range of motion is selected according to appropriate engineering principles (e.g., based on expected weight capacities, tolerances, safety, etc.).
In the example implementations of
In one implementation, the jig manipulator 100 may comprise a pitch adjustment component 112, such as a hydraulic cylinder component, operably engaged with the structural support component 110 at a first cylinder attachment point 114, and further engaged with a horizontal rotation handler 120 at a second cylinder attachment point 118. In one implementation, the pitch adjustment component 112 can be configured to adjust the horizontal rotation handler 120 around the horizontal rotatable axis 108. As an example, the pitch adjustment component 112 may be actuated to an out and/or in position by pressurized hydraulic fluid, supplied by hydraulic lines 116. As one example, when the pitch adjustment component 112 is actuated to the out position, the horizontal rotation handler 120 can be horizontally rotated in a clockwise direction around the horizontal rotatable axis 108. In this way, the vertical rotation handler 104 engaged with the door handling jig (not shown) may also be horizontally rotated in a clockwise direction (e.g., to match the plane face of the target door). Further, in this example, when the pitch adjustment component 112 is actuated to the in position, the horizontal rotation handler 120 can be horizontally rotated in a counter-clockwise direction around the horizontal rotatable axis 108.
Now with reference to
In the exemplary implementations of
As described above, the structural support component 110 can comprise a horizontal rotatable axis 108. The horizontal rotatable axis 108 may be formed by a first horizontal bushing 312a (e.g., comprising a first horizontal through hole) disposed in the first side structural member 302a and a second horizontal bushing 312b (e.g., comprising a second horizontal through hole) disposed in the second side structural member 302b. Further, a horizontal pivot pin 306 may be disposed along the horizontal rotatable axis 108 to selectively engage the horizontal rotation handler 120 (as shown in
The structural support component 110 can comprise a first cylinder attachment point 114, to which a first side of a hydraulic cylinder 112 may be selectively engaged. The first cylinder attachment point 114 may be formed by a first cylinder attachment bushing 310a (e.g., comprising a first cylinder attachment through hole) disposed in the first side structural member 302a and a second cylinder attachment bushing 310b (e.g., comprising a second cylinder attachment through hole) disposed in the second side structural member 302b. Further, a first cylinder attachment pivot pin 308 may selectively engage the hydraulic cylinder 112 with the first horizontal bushing 310a and the second horizontal bushing 310b of the first cylinder attachment point 114.
As illustrated in
Further, the first horizontal rotation handler side plate 408a can comprise a third horizontal rotation bushing 416a (e.g., comprising a third horizontal rotation through hole), and the second horizontal rotation handler side plate 408b can comprise a fourth horizontal rotation bushing 416b (e.g., comprising a fourth horizontal rotation through hole). The third horizontal rotation bushing 416a and the fourth horizontal rotation bushing 416b can be configured to receive the horizontal pivot pin 306 in order to selectively engage the horizontal rotation handler 120 with the structural support component 110 in horizontal rotation. Further, in one implementation, the third horizontal rotation bushing 416a and the fourth horizontal rotation bushing 416b can comprise a horizontal pivot coupler 418, for example, in conjunction with the horizontal pivot pin 306, for selective coupling with the structural support component 110.
Additionally, the first horizontal rotation handler side plate 408a and the second horizontal rotation handler side plate 408b can respectively be attached (e.g., welded, fastened) to a horizontal rotation handler front plate 412. In one implementation, the respective first horizontal rotation handler side plate 408a and the second horizontal rotation handler side plate 408b may be attached in a parallel arrangement (as shown in
In one implementation, the first horizontal rotation handler side plate 408a, the second horizontal rotation handler side plate 408b, and the horizontal rotation handler front plate 412 may respectively be formed from a steel product, such as an ASTM A572 grade 50 specified steel product (e.g., having a minimum yield of 50 k.s.i.). In other implementations, the first horizontal rotation handler side plate 408a, the second horizontal rotation handler side plate 408b, and the horizontal rotation handler front plate 412 may respectively be formed from a suitable material selected by appropriate engineering practices for the desired use. As one example, a high-strength polymer (e.g., or polymer combination) may be utilize where high temperatures (e.g., from a coke oven) are not expected for the desired use.
In the example implementation of
In one implementation, the respective vertical rotation plates 406 may be suitably sized and shaped in accordance with appropriate engineering principles for a desired use. In one implementation, the respective vertical rotation plates 406 may be formed from a steel product, such as an ASTM A572 grade 50 specified steel product (e.g., having a minimum yield of 50 k.s.i.). In other implementations, the respective vertical rotation plates 406 may be formed from a suitable material selected by appropriate engineering practices for the desired use. As one example, a high-strength polymer (e.g., or polymer combination) may be utilize where high temperatures (e.g., from a coke oven) are not expected for the desired use.
In the example implementation of
As illustrated in
In the example implementation of
In one implementation, the second top vertical rotation plate 502 and second bottom vertical rotation plate 504 may be suitably sized and/or shaped in accordance with appropriate engineering principles for a desired use. In one implementation, a size and/or shape of one or more of the first top vertical rotation plate 406a, first bottom vertical rotation plate 406b, second top vertical rotation plate 502, and second bottom vertical rotation plate 504 can determine a range of vertical rotation around the vertical rotation axis 106, for the vertical rotation handler 104.
As one example, a larger sized and suitably shaped second bottom vertical rotation plate 504, as illustrated in
In one implementation, the second top vertical rotation plate 502, second bottom vertical rotation plate 504, and vertical rotation handler front plate 510 may be formed from a steel product, such as an ASTM A572 grade 50 specified steel product (e.g., having a minimum yield of 50 k.s.i.). In other implementations, the respective vertical rotation plates 406 may be formed from a suitable material selected by appropriate engineering practices for the desired use. As one example, a high-strength polymer (e.g., or polymer combination) may be utilize where high temperatures (e.g., from a coke oven) are not expected for the desired use.
In the example implementation of
Further, in this example implementation, the hydraulic cylinder 112 can comprise a cylinder piston rod or shaft 604, engaged with (e.g., formed with, fastened to) a horizontal rotation handler engagement eye 608. The horizontal rotation handler engagement eye 608 can be configured to selectively engage with the second cylinder attachment pivot pin 402, for example, thereby attaching the hydraulic cylinder 112 to the horizontal rotation handler 120 at the second cylinder attachment point 118.
Additionally, the in this example implementation, the hydraulic cylinder 112 can comprise a first hydraulic fluid port 610 and a second hydraulic fluid port 612. In one implementation, the respective hydraulic fluid ports 610, 612 may be engaged with a hydraulic line 116 (e.g., of
In one implementation, as described above, when the hydraulic cylinder 112 is actuated to the out position, the horizontal rotation handler 120 can be horizontally rotated in a clockwise direction around the horizontal rotatable axis 108. In this way, the vertical rotation handler 104 engaged with the door handling jig (not shown) may also be horizontally rotated in a clockwise direction (e.g., to match the plane face of the target door). Further, in this example, when the pitch adjustment component 112 is actuated to the in position, the horizontal rotation handler 120 can be horizontally rotated in a counter-clockwise direction around the horizontal rotatable axis 108.
In one aspect, the exemplary jig manipulator may be used to manipulate a door handling jig. In one implementation of this aspect, a door handling jig can be used to engage with a cumbersome door (e.g., one not easily handled by one or two people), and/or a door that presents a safety hazard (e.g., proximate to a temperature-related, chemical-related, and/or radiation-related hazard). As an example, an industrial furnace/oven (e.g., in a coke processing plant) can typically comprises a plurality of access doors, which can be used to access portions of the interior of the furnace (e.g., for operations, maintenance, loading, unloading, etc.). In this example, a door handling jig, configured to engage with a furnace door, may be used to open, close, and/or remove and replace the door. Further, in this example, the exemplary jig manipulator may be used to manipulate a door handling jig to facilitate the opening, closing, and/or removal and replacement of the door.
As an illustrative example, the access doors to industrial furnaces can comprise a type of insulating material applied to an inside of the door. For example, refractory material is often applied to an interior of a metal door to mitigate heat loss, and/or to mitigate damage (e.g., melting) to the door. In this example, when the insulating material reaches the end of its useful operation (e.g., is no longer providing appropriate insulation to the door) an operator may wish to remove and replace the door and/or insulation. Further, some industrial furnaces can remain in near constant operation, even during times of door replacement.
As an example, when a door's insulation is no longer useful, the door may become very hot (e.g., glow red-hot), indicating a need for replacement of the insulation and/or door. In this example, an operator may wish to remove and replace the door quickly and safely, as the furnace operation may provide an unsafe condition, and heat-loss may be crucial during the furnaces operation. In one implementation, the door handling jig may be engaged with the exemplary jig manipulator, which may be engaged with an appropriate crane (e.g., a hydraulic extension crane). In this implementation, for example, the operator can utilize the crane, exemplary jig manipulator, and door handling jig to safely and quickly remove and replace the door.
Some furnace doors may weigh in excess of twelve thousand pounds and may be twelve feet long or more. Further, an area of operation (e.g., space available to access the doors) may be quite limited in some industrial applications. As an example, the operator may identify a door that needs to be replaced. The operator can mobilize the crane, with the attached jig manipulator and door jig, to the site of the door. The crane may locate proximate to the door, and the jig manipulator can be manipulated in both the vertical and horizontal rotation axes, thereby engaging the door handling jig with the door in a more efficient manner (e.g., more quickly and safely). In this example, the target door can be quickly removed from the furnace using the crane, jig manipulator and door jig; and a replacement door may be quickly installed using the crane, jig manipulator and door jig. Previously door removal and replacement may have taken thirty minutes or more, leading to potentially unsafe conditions and/or critical heat-loss. Utilizing the jig manipulator, removal and replacement may merely take five minutes, for example, as the door handing jig can be quickly engaged with the target door, unlike previous door removal techniques.
