Description

Technical Field

[0001] This application belongs to the field of coal mine equipment technology, specifically relating to a batch pull-out device for column guide sleeves. Background Technology

[0002] Disassembling the column guide sleeve is a very important procedure in the maintenance of hydraulic supports. In addition, the column is the main supporting component of the hydraulic support. There are many of them, and they need to be inspected in batches, which makes the workload very large.

[0003] The traditional method of disassembling guide sleeves for vertical columns involves workers manually pushing an old-style guide sleeve removal tool to the front of the column to be removed, then manually separating the two hooks of the old-style tool and locking them against the edge of the guide sleeve. Workers then operate a high-pressure valve on-site to pull out and disassemble the guide sleeve. This process, involving close proximity, manual operation, and single-sleeve removal, is not only inefficient but also poses safety hazards such as tool popping up and causing injury, hooks flying out and causing injury, and high-pressure liquid injury from broken tubing. Therefore, designing and manufacturing a new batch guide sleeve removal device is urgently needed. Utility Model Content

[0020] The preferred embodiments of this application are described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit this application.

[0021] like Figures 1 to 5As shown in the embodiment of this application, a batch removal device for column guide sleeves is proposed, comprising: a lifting support body 11, a guiding mechanism 12, and a pulling device 13; the lifting support body 11 is arranged horizontally, and the column 14 is placed above the lifting support body 11 parallel to the width direction of the lifting support body 11; the guiding mechanism 12 is arranged parallel to the length direction of the lifting support body 11 and is disposed outside the lifting support body 11; the pulling device 13 is slidably connected to the guiding mechanism 12, and the pulling device 13 is engaged with the guide sleeve 15 of the column 14 so as to remove the guide sleeve 15 from the column 14 by means of the pulling device 13.

[0022] The column guide sleeve batch removal device provided in this application embodiment includes a lifting support body 11, a guiding mechanism 12, and a pulling device 13. The lifting support body 11 is used to store columns 14 in batches. The columns 14 are arranged along the length direction of the lifting support body 11. The guiding mechanism 12 extends along the length direction of the lifting support body 11. The pulling device 13 slides on the guiding mechanism 12. When the pulling device 13 is aligned with the column 14, the pulling device 13 is controlled to hook the guide sleeve 15 on the column 14. The pulling device 13 pulls the guide sleeve 15 away from the column 14, thus removing the guide sleeve 15 from the column 14. Then, the pulling device 13 is controlled to move away from the column 14. Move to the position aligned with the next column 14 to be pulled out guide sleeve 15, and pull out the guide sleeves 15 of all the columns 14 placed on the lifting support body 11 in sequence, completing the removal of the entire batch of column guide sleeves 15. The guide sleeve 15 batch removal device has multiple workstations. By using the column guide sleeve batch removal device, the operation method of removing column guide sleeves 15 by close distance, manually, and one by one is replaced by the operation method of removing column guide sleeves 15. This eliminates multiple possible safety hazards that may occur during the removal of guide sleeves 15, such as tool popping up and injuring people, hook jumping out and injuring people, and high pressure liquid injury from broken liquid pipes. At the same time, it reduces the intensity of manual labor and effectively improves the efficiency of hydraulic support column 14 maintenance.

[0023] like Figures 2 to 5 As shown, in one feasible embodiment, the lifting support 11 includes: a first base plate 111, a frame 112, and a lifting cylinder 113; the first base plate 111 is fixed on the ground; the frame 112 is horizontally arranged above the first base plate 111; the lifting cylinder 113 is vertically arranged, the fixed end of the lifting cylinder 113 is connected to the first base plate 111, and the telescopic end of the lifting cylinder 113 is connected to the frame 112, and the lifting cylinder 113 drives the frame 112 to perform lifting and lowering movements; wherein, the columns 14 are placed on the frame 112 at equal intervals along the length direction of the frame 112.

[0024] In this technical solution, the first base plate 111 is fixed on the ground, the frame 112 is horizontally arranged above the first base plate 111, and the column 14 is placed on the frame 112. The frame 112 and the first base plate 111 are connected by a lifting cylinder 113. The height of the frame 112 is adjusted by extending and retracting the lifting cylinder 113, thereby adjusting the height of the column 14 so that the axis of the column 14 is at the same height as the pulling device 13, and the column 14 and the pulling device 13 are aligned in the height direction. This ensures the concentricity of the subsequent guide sleeve 15 and the pulling device 13, avoids uneven force on the guide sleeve 15 due to non-concentricity with the pulling device 13 during the pulling process, and prevents the pulling device 13 from popping up or the hook from jumping out, thus ensuring the safety of the maintenance of the hydraulic support column 14.

[0025] In this technical solution, the columns 14 are placed at equal intervals along the length of the frame 112, that is, the axial spacing of two adjacent columns 14 is consistent, so that the distance of each step of the pulling device 13 is consistent, eliminating the need to repeatedly calculate the step distance of the pulling device 13, and improving the convenience of control and use of the batch pulling device of the guide sleeve 15.

[0026] Furthermore, the batch removal device for the column guide sleeves also includes a control box. The control box is the control part of the entire batch removal device for the guide sleeves 15. The lifting cylinder 113, the guide mechanism 12, and the pulling device 13 are connected to the control box. The control box is located away from the lifting support body 11. The operator can remotely control the batch removal device for the guide sleeves 15 through the control box, enabling the operator to complete the removal of the guide sleeves 15 from a location away from the on-site work area. As a preferred embodiment, the lifting cylinder 113, the guide mechanism 12, and the pulling device 13 are connected to the control box through high-pressure hydraulic pipes.

[0027] like Figure 2 and Figure 3 As shown, in one feasible embodiment, the column guide sleeve batch pull-out device further includes: a positioning plate assembly and a positioning groove 17; the positioning plate assembly includes at least two positioning plates 16, the positioning plates 16 are arranged along the width direction of the lifting support body 11, the column 14 is placed above the positioning plates 16, and the positioning plates 16 near the pulling device 13 are embedded in the annular groove of the column 14; the positioning groove 17 is provided on the top surface of the positioning plate 16, and the lowest point of the outer circle of the column 14 is located in the positioning groove 17.

[0028] In this technical solution, the frame 112 is provided with multiple positioning plate assemblies. The frame 112 is a multi-station structure. One column 14 is placed on one positioning plate assembly. One column 14 is supported by multiple positioning plates 16. The positioning plate 16 is provided with positioning grooves 17. The column 14 is placed in the positioning grooves 17 so as to radially limit the column 14 through the positioning grooves 17, prevent the column 14 from rolling to both sides, and ensure that the axial distance between two adjacent columns 14 is consistent, thereby ensuring the consistency of the stepping distance of the pulling device 13.

[0029] In some examples, the positioning groove 17 is arc-shaped or V-shaped to accommodate columns 14 of different sizes.

[0030] like Figures 2 to 5 As shown, in one feasible embodiment, the guide mechanism 12 includes: a second base plate 121, a slide rail 122, a pulling mechanism 123, and a moving cylinder 124; the second base plate 121 is fixed on the ground; the slide rail 122 is arranged parallel to the length direction of the lifting support body 11 and extends along the length direction of the lifting support body 11; the pulling mechanism 123 is slidably connected to the slide rail 122; the moving cylinder 124 is arranged horizontally along the length direction of the lifting support body 11, the fixed end of the moving cylinder 124 is connected to the slide rail 122, and the telescopic end of the moving cylinder 124 is connected to the pulling mechanism 123, and the moving cylinder 124 drives the pulling mechanism 123 to move along the length direction of the lifting support body 11.

[0031] In this technical solution, the second base plate 121 is fixed on the ground. The movement of the pulling mechanism 123 is driven by the moving cylinder 124. The slide rail 122 guides the movement of the pulling mechanism 123, so that the pulling mechanism 123 moves along the length of the lifting support 11 to each work position. Thus, by moving the pulling mechanism 123, the guide sleeves 15 of the columns 14 placed on the lifting support 11 are pulled out in sequence. When the fixed end of the moving cylinder 124 is fixed on the slide rail 122, the position of the pulling mechanism 123 is quickly adjusted by controlling the extension and retraction length of the moving cylinder 124. Then, by the action of the pulling mechanism 123, the guide sleeves 15 are automatically pulled out. During the operation, the operator does not need to approach the work area, ensuring the safety of the operator's life and health.

[0032] like Figure 2 , Figure 4 and Figure 5As shown, in one feasible embodiment, the pulling mechanism 123 includes: an adjusting seat 1231, a movable seat 1232, a pulling assembly 1233, and a feed cylinder 1234; the adjusting seat 1231 is slidably connected to the slide rail 122; the movable seat 1232 is slidably connected to the slide rail 122; the fixed end of the movable cylinder 124 is connected to the adjusting seat 1231, and the telescopic end of the movable cylinder 124 is connected to the movable seat 1232, and the movable cylinder 124 drives the movable seat 1232 to move relative to the adjusting seat 1231; the pulling assembly 1233 is slidably connected to the movable seat 1232; the feed cylinder 1234 is arranged horizontally along the width direction of the lifting support 11, the fixed end of the feed cylinder 1234 is connected to the pulling assembly 1233, and the telescopic end of the feed cylinder 1234 is connected to the movable seat 1232, and the feed cylinder 1234 drives the pulling assembly 1233 to move along the width direction of the lifting support 11.

[0033] In this technical solution, the pulling mechanism 123 is a split structure. The adjusting seat 1231 and the moving seat 1232 are connected by the moving cylinder 124. The pulling assembly 1233 is installed on the moving seat 1232. The feed cylinder 1234 extends and retracts to drive the pulling assembly 1233 to move along the width direction of the lifting support body 11, so that the pulling assembly 1233 moves closer to or away from the column 14, thereby enabling the pulling assembly 1233 to approach the column 14 and hook the guide sleeve 15, or after the pulling assembly 1233 hooks the guide sleeve 15, the pulling assembly 1233 moves away from the column 14 to pull out the guide sleeve 15. When the adjusting seat 1231 is locked onto the slide rail 122 and the moving seat 1232 is not locked onto the slide rail 122, the moving cylinder 124 extends and retracts, causing the moving seat 1232 and the pulling assembly 1233 to slide along the slide rail 122, so that the pulling assembly 1233 moves quickly to each work position on the lifting support 11; when the adjusting seat 1231 is not locked onto the slide rail 122 and the moving seat 1232 is locked onto the slide rail 122, the extending and retracting end of the moving cylinder 124 is fixed onto the slide rail 122 along with the moving seat 1232, and the extending and retracting of the moving cylinder 124 adjusts the position of the fixed end of the moving cylinder 124, thereby adjusting the position of the adjusting seat 1231 on the slide rail 122, through the adjusting seat 1231 and the moving seat 1232 Alternating locking mechanisms are engaged on slide rail 122, and adjusting seat 1231 is continuously moved towards moving seat 1232, so that the entire pulling mechanism 123 can slide on slide rail 122. By moving the entire pulling mechanism 123 towards the far end column 14, the situation where moving cylinder 124 cannot extend to the far end position is avoided. The position of adjusting seat 1231 is adjusted by moving the fixed end of moving cylinder 124, so that pulling assembly 1233 can quickly approach the far end column 14, shortening the moving distance and time of pulling assembly 1233, and reducing the length, volume and weight of moving cylinder 124. Pulling mechanism 123 is compact and highly adaptable, saving production and usage costs.

[0034] like Figure 2 and Figure 6 As shown, in one feasible embodiment, the column guide sleeve batch pull-out device further includes: a first limiting member 18 and a first locking cylinder 19. The first limiting member 18 is disposed at the bottom of the adjusting seat 1231, and the first limiting member 18 and the adjusting seat 1231 form a first receiving space, through which the slide rail 122 passes. The first locking cylinder 19 is vertically disposed, and the fixed end of the first locking cylinder 19 is connected to the adjusting seat 1231. The second base plate 121 is pressed against the first locking cylinder 19, raising the adjusting seat 1231 so that the first limiting member 18 contacts the slide rail 122, thus fixing the adjusting seat 1231 on the slide rail 122.

[0035] In this technical solution, the adjusting seat 1231 is locked and automatically controlled by the first locking cylinder 19. When the adjusting seat 1231 slides, it slides in contact with the slide rail 122. The first limiting member 18 is set at the bottom of the adjusting seat 1231, and the slide rail 122 passes through the first receiving space. By connecting the fixed end of the first locking cylinder 19 to the adjusting seat 1231 and setting the first locking cylinder 19 vertically, when the first locking cylinder 19 extends, it presses against the second base plate 121. Due to the reaction force of the second base plate 121 on the first locking cylinder 19, the first... The fixed end of the locking cylinder 19 lifts the adjusting seat 1231 upward, separating the adjusting seat 1231 from the slide rail 122, and pressing the first limiting member 18 tightly onto the slide rail 122, increasing the friction between the first limiting member 18 and the slide rail 122, thereby locking the position of the adjusting seat 1231. At this time, the movement of the pulling assembly 1233 is driven by the moving cylinder 124. When the first locking cylinder 19 retracts, the adjusting seat 1231 falls back under its own gravity, the first limiting member 18 separates from the slide rail 122, and the adjusting seat 1231 contacts the slide rail 122, restoring the moving function of the adjusting seat 1231.

[0036] like Figures 2 to 5 As shown, in one feasible embodiment, the column guide sleeve batch pull-out device further includes: a second limiting member 20 and a second locking cylinder 21; the second limiting member 20 is disposed at the bottom of the movable seat 1232, and the second limiting member 20 and the movable seat 1232 form a second accommodating space, through which the slide rail 122 passes; the second locking cylinder 21 is vertically disposed, and the fixed end of the second locking cylinder 21 is connected to the movable seat 1232. The second locking cylinder 21 is extended and pressed against the second base plate 121, thereby lifting the movable seat 1232, so that the second limiting member 20 contacts the slide rail 122, and the movable seat 1232 is fixed on the slide rail 122.

[0037] In this technical solution, the movable seat 1232 is locked and automatically controlled by the second locking cylinder 21. When the movable seat 1232 slides, it slides in contact with the slide rail 122. The second limiting member 20 is set at the bottom of the movable seat 1232, and the slide rail 122 passes through the second receiving space. By connecting the fixed end of the second locking cylinder 21 to the movable seat 1232 and setting the second locking cylinder 21 vertically, when the second locking cylinder 21 extends, it presses against the second base plate 121. Due to the reaction force of the second base plate 121 on the second locking cylinder 21, the fixed end of the second locking cylinder 21 lifts the movable seat 1232 upward, so that the movable seat 1232 and the slide rail... When the second limiting member 20 is separated from the slide rail 122, the second limiting member 20 is pressed tightly against the slide rail 122, increasing the friction between the second limiting member 20 and the slide rail 122, thereby locking the position of the moving seat 1232. At this time, the position of the pulling assembly 1233 in the length direction of the lifting support body 11 is locked, preventing the pulling assembly 1233 from shifting during the pulling process, and ensuring the structural stability and reliability of the pulling assembly 1233. When the second locking cylinder 21 retracts, the moving seat 1232 falls back under its own gravity, the second limiting member 20 separates from the slide rail 122, and the moving seat 1232 contacts the slide rail 122, restoring the moving function of the moving seat 1232, so that the pulling assembly 1233 can move quickly to the next station.

[0038] Understandably, when the first locking cylinder 19 extends, its extended end abuts against the second base plate 121, at which point the adjusting seat 1231 is fixed to the slide rail 122. The second locking cylinder 21 retracts, leaving a gap between its extended end and the second base plate 121, i.e., the second limiting member 20 separates from the slide rail 122. At this point, the moving seat 1232 is in a free state, and the extension and retraction of the moving cylinder 124 can quickly drive the moving seat 1232 to move along the length of the lifting support 11. When the first locking cylinder 19 retracts and the second locking cylinder 21 extends, the moving seat 1232 is fixed to the slide rail 122 by the second locking cylinder 21. By controlling the fixed end of the moving cylinder 124 to retract towards the moving seat 1232, the adjusting seat 1231 moves forward, thereby enabling the entire pulling mechanism 123 to automatically shift along the slide rail 122. By repeating the above steps, the pulling mechanism 123 can move along the slide rail 122 for its entire stroke along the length of the lifting support body 11.

[0039] like Figure 5 and Figure 6As shown, in one feasible embodiment, the pull assembly 1233 includes: a base 12331, two crossbars 12332, two hooks 12333, two swing cylinders 12334, and a reverse thrust cylinder 12335; the base 12331 is slidably connected to the movable seat 1232; the crossbars 12332 are horizontally arranged and extend along the length direction of the lifting support 11, with the ends of the crossbars 12332 connected to the base 12331, and the two crossbars 12332 are respectively arranged on both sides of the base 12331; the first end of the hook 12333 is rotatably connected to the crossbar 12332, and the hook...
