In order to better support the coal wall during the coal mining process, prevent the front end of the top beam of the hydraulic support from being too far away from the coal wall, causing the roof coal and rock to collapse and harm the man-machine, the telescopic beam is installed on the hydraulic support used in most medium-thick coal seams. During the maintenance of the hydraulic support, the telescopic beam is mostly disassembled by using the way of hanging and lifting by the crown block and dragging by the forklift, and some are disassembled by separating the top beam first and then disassembling the telescopic beam on the ground.

[0027] It should be noted that all technical and scientific terms used in the present application have the same meaning as commonly understood by one of ordinary skill in the art to which the present application belongs, unless otherwise specified.

[0028] In the present application, unless otherwise specified, the orientation words such as "up, down, top, bottom" are generally directed to the directions shown in the drawings, or are directed to the vertical, perpendicular or gravity directions of the components themselves; similarly, for the convenience of understanding and description, "inner, outer" refers to the inner and outer relative to the contour of the components themselves, but the above orientation words are not used to limit the present application.

[0029] In order to solve the problem of inconvenient disassembly of the telescopic beam of the coal mine hydraulic support in the prior art, the present application provides a telescopic beam disassembling device and a telescopic beam disassembling system.

[0030] Furthermore, the telescopic beam disassembling system in the present application has the following telescopic beam disassembling device.

[0031] As shown in Figures 1 to 4 The telescopic beam disassembling device in the present application includes a fixed frame 10, a movable frame 20, a driving assembly 30 and a clamping assembly 40. The movable frame 20 is movably connected with the fixed frame 10, and at least a part of the movable frame 20 can move in the direction of approaching or moving away from the fixed frame 10. The end of the movable frame 20 away from the fixed frame 10 has an insertion structure 21 in the thickness direction of the movable frame 20, which is used to insert the gap of the telescopic beam. The driving assembly 30 is arranged on the fixed frame 10, and the driving end of the driving assembly 30 is connected with the movable frame 20 to drive the movable frame 20 to move in the direction of approaching or moving away from the fixed frame 10. At least a part of the clamping assembly 40 is movably arranged on both sides of the end of the movable frame 20 away from the fixed frame 10 and forms a clamping space with the movable frame 20.

[0032] When the telescopic beam disassembling device in the application is used, the telescopic beam disassembling device can be positioned on the top beam through the fixing frame 10, and since the movable frame 20 is connected with the fixing frame 10 and the movable frame 20 has the insertion structure 21, when the insertion structure 21 is inserted into the gap of the telescopic beam 70 to be disassembled, the driving assembly 30 can drive the movable frame 20 to move relative to the fixing frame 10, so that the movable frame 20 can drive the telescopic beam 70 to move, thereby realizing the disassembly of the telescopic beam. At the same time, since the telescopic beam disassembling device also has the clamping assembly 40, during the movement of the telescopic beam driven by the movable frame 20, the telescopic beam 70 can be clamped by the clamping assembly 40, that is, the telescopic beam is clamped by the clamping space formed by the movable frame 20 and the clamping assembly 40, so that the telescopic beam can be effectively prevented from falling off after disassembly, thereby effectively ensuring the operation safety of the telescopic beam disassembling device. Therefore, the telescopic beam disassembling device in the application effectively solves the problem of inconvenient disassembly of the telescopic beam of the coal mine hydraulic support in the prior art.

[0033] Specifically, the movement direction of the movable frame 20 is the same as the length direction of the movable frame 20, and the clamping assembly 40 is arranged on both sides of the length direction of the movable frame 20.

[0034] In one specific embodiment of the application, the insertion structure 21 includes at least two top rods 211 arranged at intervals along the width direction of the movable frame 20, and the top rods 211 are movably arranged on the movable frame 20 so that the distance between the two top rods 211 can be adjusted. That is, in this embodiment, by adjusting the distance between the two top rods 211, it can be ensured that the two top rods 211 can be inserted into the gaps of the telescopic beam respectively, so that when the movable frame 20 moves relative to the fixing frame 10 under the action of the driving assembly 30, the movable frame 20 can drive the telescopic beam to move together under the action of the top rods 211. Therefore, in the application, the adjustment distance between the two top rods 211 is determined according to the distance between the two gaps of the telescopic beam into which the two top rods 211 are inserted.

[0035] Optionally, the movable frame 20 has a driving cavity, and the driving assembly 30 includes at least two driving oil cylinders 31, the driving oil cylinders 31 are arranged on the fixing frame 10, and the driving ends of the driving oil cylinders 31 are drivingly connected with the inner wall of the driving cavity.

[0036] Specifically, the holding assembly 40 comprises two holding units symmetrically arranged along the length direction of the movable frame 20, and each holding unit comprises a holding oil cylinder 41 and a clamping rod set 42. The holding oil cylinder 41 and the insertion structure 21 are respectively located on the two sides of the movable frame 20 in the thickness direction. One end of the clamping rod set 42 is drivingly connected with the holding oil cylinder 41, and the other end of the clamping rod set 42 extends around the movable frame 20 and towards the insertion structure 21. Through such an arrangement, when the movable frame 20 moves relative to the fixed frame 10, the two holding units are first adjusted, so that the holding oil cylinders 41 of the two holding units respectively drive the clamping rod sets 42 to move, so as to expand the clamping space between the two clamping rod sets 42, so that the telescopic beam can be aligned with the clamping space. Then, the holding oil cylinders 41 of the two holding units drive the clamping rod sets 42 to move in the opposite direction, so that the two clamping rod sets 42 can hold the telescopic beam, thereby ensuring that the telescopic beam will not fall off the movable frame 20 when the movable frame 20 drives the telescopic beam to move, so as to ensure the safety performance of the telescopic beam disassembling device.

[0037] In a specific embodiment of the present application, the clamping rod set 42 comprises a first connecting rod and a second connecting rod connected in sequence. One end of the first connecting rod away from the second connecting rod is drivingly connected with the holding oil cylinder 41, and the first connecting rod and the second connecting rod have a connecting angle therebetween. The second connecting rod is L-shaped. Through such an arrangement, it can be ensured that the two oppositely arranged clamping rod sets 42 can form a clamping jaw structure similar to a mechanical claw under the action of the holding oil cylinder 41, so as to realize clamping or loosening of the telescopic beam.

[0038] Of course, the holding assembly 40 in the present application can also be other structure assemblies capable of realizing holding or loosening.

[0039] Preferably, the telescopic beam disassembling device further comprises at least two anti-falling hooks 50 symmetrically arranged relative to the movable frame 20. The two anti-falling hooks 50 are movably arranged at one end of the movable frame 20 away from the fixed frame 10, and the two anti-falling hooks 50 are located on the two sides of the movable frame 20 in the movement direction.

[0040] Optionally, the anti-falling hooks 50 and the holding assembly 40 are arranged at intervals along the movement direction of the movable frame 20.

[0041] Specifically, one side of the fixed frame 10 in the thickness direction has at least two clamping plates 60. One side of the clamping plate 60 away from the movable frame 20 has a clamping surface extending along the thickness direction of the fixed frame 10. Through such an arrangement, it can be ensured that the fixed frame 10 can abut against the edge of the top beam through the clamping plate 60, so as to ensure the stability of the fixed frame 10 when the driving assembly 30 drives the movable frame 20 to move relative to the fixed frame 10, so as to prevent relative movement between the fixed frame 10 and the top beam.

[0042] In one specific embodiment of the present application, the fixed frame is placed above the top beam, and the triangular clamping plates are placed at both sides below the fixed frame as the fulcrum when the telescopic beam is disassembled. The movable frame is connected with the fixed frame by a large-stroke oil cylinder, and the movable frame is provided with two front jacks, the distance between the two jacks can be adjusted, and when the telescopic beam is disassembled, the jacks are inserted into the two gaps in the middle of the telescopic beam as the fulcrum for jacking out the telescopic beam.

[0043] In one specific embodiment of the present application, the working process of the device is as follows: the clamping oil cylinder is extended, and the clamping rod group is opened. The anti-falling hook is adjusted to be parallel to the extension direction of the movable frame. The width of the front jacks of the movable frame is adjusted to be the same as the width of the gap in the middle of the telescopic beam. The device is placed above the top beam of the hydraulic support by the hoist group, the triangular clamping plates below the fixed frame are placed between the top beam and the telescopic beam, and the jacks below the movable frame are placed in the middle of the two gaps of the telescopic beam. The clamping oil cylinder is retracted, the clamping rod group clamps the telescopic beam, at the same time, the anti-falling hook is rotated by 90° to hang below the front of the telescopic beam, and then the nut above the anti-falling hook is tightened to make the anti-falling hook fit the telescopic beam. The large-stroke oil cylinder is extended to push the movable frame out of the telescopic beam, the device and the telescopic beam are hoisted to the ground, the nut of the anti-falling hook is loosened, the anti-falling hook is loosened, the clamping oil cylinder is opened to loosen the telescopic beam, and then the device is hoisted away to complete the disassembly of the telescopic beam.
