Description

Technical Field

[0001] This invention relates to the field of subsidence treatment technology, and in particular to a device for backfilling and repairing coal mine subsidence areas. Background Technology

[0002] As coal mines begin to be mined, their internal structure and stress conditions change. Daily use also causes localized wear and damage to the mine tunnels, making them prone to collapse. This severely impacts mining safety and overall work efficiency. Therefore, workers first need to backfill and repair the collapsed areas. Currently, this is mainly done by backfilling with mine soil and compacting the resulting base. However, this process of repairing coal mine collapse areas presents the following problems: 1. After backfilling, the stress around the collapsed area remains unstable, making secondary collapses more likely and reducing mining safety.

[0003] 2. Because the coal mine subsidence area is located within the mine tunnel, the operational space for backfilling and repair is relatively small. Therefore, manual backfilling and repair requires a large number of workers to coordinate the operation, which not only makes the space congested but also reduces the efficiency of manual backfilling and repair, affecting the normal use of the mine tunnel and thus impacting normal coal mining.

[0026] The embodiments of the present invention will be described in detail below with reference to the accompanying drawings, but the present invention can be implemented in many different ways as defined and covered by the claims.

[0027] See Figure 1 , Figure 3 and Figure 6 A coal mine subsidence area backfilling and repair treatment device includes a base plate 1, walking components 2, a repair mechanism 3, and an auxiliary mechanism 4. The base plate 1 is horizontally arranged, and four walking components 2 are fixedly arranged in a matrix on the lower end face of the base plate 1. Four telescopic rods 10 are fixedly arranged in a matrix on the lower end face of the base plate 1. All the telescopic rods 10 are fixedly connected to a lifting plate 11. The repair mechanism 3 is set in the subsidence area, and the auxiliary mechanism 4 is set on the lifting plate 11.

[0028] See Figure 3 The repair mechanism 3 includes an arc-shaped plate 30. Four arc-shaped plates 30 are arranged in a matrix within the collapsed area. The outer arc surface of the arc-shaped plate 30 is in close contact with the inner wall of the collapsed area. Two vertically distributed placement plates 31 are fixedly arranged on the opposite surfaces of two arc-shaped plates 30 in the longitudinal plane. A support plate 32 is placed above the two corresponding placement plates 31. A matching plate 33 is placed above the support plate 32. Both ends of the support plate 32 and the matching plate 33 are arc-shaped structures and are in close contact with the inner arc surface of the corresponding arc-shaped plate 30. Multiple placement components 34 are fixedly arranged along the axis of the lower end of the arc-shaped plate 30. The lower end of the placement component 34 is divided into a pointed structure.

[0029] During the work, the area to be collapsed is first initially backfilled and repaired manually, forming a cylindrical deep pit. The area above is cleared and shaped to accommodate a reinforced concrete slab. Then, an arc-shaped plate 30 is placed manually into the collapsed area, ensuring that the outer arc surface of the arc-shaped plate 30 is in close contact with the inner wall of the collapsed area. The placement piece 34, with its pointed structure, facilitates the insertion of the arc-shaped plate 30 into the collapsed area. Next, a support plate 32 is placed on the two corresponding placement plates 31. Then, a mating plate 33 is placed and installed in the same way, with the mating plate 33 placed on the support plate 32. Thus, the support plate 32 and the mating plate 33 support and compress the corresponding arc-shaped plate 30 through their arc-shaped structures at both ends, thereby stabilizing the collapsed area after backfilling and repair, preventing secondary collapse, and facilitating subsequent repair of the collapsed area.

[0030] See Figure 3 and Figure 5 The upper end surface of the arc plate 30 is provided with a placement groove 35 that corresponds to and cooperates with the support plate 32 or the mating plate 33, and the placement groove 35 is an arc-shaped structure.

[0031] During operation, after the arc plate 30 is placed in the collapse zone by means of the placement piece 34, the inner wall of the collapse zone exerts a squeezing force on the placed arc plate 30. Therefore, the placement groove 35 is set at this time to facilitate the placement of the corresponding support plate 32 and mating plate 33 between the corresponding two arc plates 30, thereby improving the convenience of device operation.

[0032] See Figure 1 , Figure 3 , Figure 4 and Figure 5The auxiliary mechanism 4 includes fixed columns 40. Four fixed columns 40 arranged in a matrix are fixedly installed on the upper surface of the lifting plate 11. An operating plate 400 is installed on each fixed column 40. The operating plate 400 has a sliding groove corresponding to each fixed column 40, and the operating plate 400 slides relative to the fixed columns 40. Two symmetrically arranged lifting cylinders 401 are fixedly installed at the lower end of the lifting plate 11. The telescopic ends of the lifting cylinders 401 are fixedly connected to the operating plate 400. Two symmetrically arranged H-shaped combination grooves 402 are opened on the lower surface of the operating plate 400. The upper surface of the lifting plate 11... Each combination groove 402 is provided with a through groove 403 corresponding to the combination groove 402, and the shape of the through groove 403 is the same as that of the combination groove 402. Two left-right symmetrical operating bars 404 are slidably arranged in each combination groove 402. The rear end face of the two front operating bars 404 and the opposite face between them are fixedly provided with operating columns 405. The front end face of the two rear operating bars 404 and the opposite face between them are fixedly provided with operating columns 405. The opposite face of the support plate 32 and the mating plate 33 to the corresponding non-contact arc plate 30 are provided with operating grooves 406 that cooperate with the operating columns 405.

[0033] During operation, after the arc-shaped plate 30 is placed in the collapsed area, the traveling member 2 moves the entire device above the collapsed area. The telescopic rod 10, being an existing pneumatic guide rod, then moves the lifting plate 11 down to a designated position. Simultaneously, the lifting cylinder 401 moves the operating plate 400 up and down via its telescopic end, allowing the lower end of the operating bar 404 on the operating plate 400 to move to a designated position. Before this, the support plate 32 is manually placed on the upper part of the corresponding two arc-shaped plates 30. Then, through the movement of the operating bar 404 within the corresponding combination groove 402, the two operating bars located in the same transverse plane... The four operating bars 404 are close to each other, and the two operating bars 404 located in the same longitudinal plane are far apart from each other. Therefore, the corresponding operating column 405 in the transverse direction of the operating bar 404 is inserted into the operating groove 406 in the support plate 32. The support plate 32 is limited and fixed by the cooperation between the four operating bars 404. Then, the lifting cylinder 401 works to drive the operating bar 404 to move down through its extension end. Therefore, the operating bar 404 causes the support plate 32 to move down through the corresponding operating column 405, so that the support plate 32 moves down to the corresponding placement plate 31 and supports the arc plate 30. Then, the corresponding mating plate 33 is placed in the same way to improve the convenience of device operation.

[0034] See Figure 4The lower end face of the operation panel 400 is fixedly provided with two symmetrical vertical plates 41. The front end face of the vertical plate 41 is provided with a control groove. A rotating shaft 410 is placed in the control groove. A drive gear 411 is fixedly sleeved on the rotating shaft 410. The two operation bars 404 located in the same horizontal plane are fixedly provided with a rack assembly on their outward-facing end faces. The rack assembly includes two movable racks 412 that mesh with the corresponding drive gears 411. A telescopic member 413 is provided between the two rotating shafts 410. Two limiting members 414 located on the front and rear sides of the corresponding drive gears 411 are fixedly sleeved on the rotating shaft 410. A pneumatic push rod 415 is fixedly provided between the two operation bars 404 located in the same vertical plane.

[0035] During operation, the external motor drives the front rotating shaft 410 to rotate, and at the same time, the front rotating shaft 410, through the transmission of the intermediate telescopic member 413, causes the rear rotating shaft 410 to rotate synchronously. Therefore, the rotating shaft 410, through the meshing of its drive gear 411 and the corresponding rack set, moves the two operating bars 404 located in the same transverse plane away from or towards each other. Simultaneously, the pneumatic push rod 415 operates to move the two operating bars 404 located in the same longitudinal plane away from or towards each other, thereby enabling all... The operating bars 404 work together to clamp the placed support plate 32 or mating plate 33. At the same time, the operation of the lifting cylinder 401 can move the support plate 32 and mating plate 33 to the designated position, which facilitates the support operation of the arc plate 30. Meanwhile, the movement of the corresponding two operating columns 405 in the corresponding operating slots 406 keeps the support plate 32 or mating plate 33 horizontal, avoiding the problem that the support plate 32 or mating plate 33 is not horizontal when it moves, resulting in poor support effect for the arc plate 30.

[0036] See Figure 5 , Figure 6 and Figure 7The operating bar 404 has a limiting groove on its front end face. A cross-shaped mounting block 42 is provided between the four operating bars 404. Two symmetrical sliding grooves 420 are provided on both the front and rear end faces of the mounting block 42. A limiting post 421 located in the limiting groove is slidably disposed within the sliding groove 420. Telescopic grooves are provided on all four end faces of the mounting block 42. Telescopic posts 422 are slidably disposed within the telescopic grooves. Two symmetrical mating parts 423 are fixedly disposed on the inner arc surface of the arc plate 30. The end face of the mating part 423 away from the corresponding arc plate 30 has a mating groove that mates with the telescopic post 422. The inner wall of the mating groove is chamfered. A rack groove 424 is provided on the upper end face of each of the four branches of the mounting block 42. A connecting block is slidably disposed within the rack groove 424, with the connecting blocks on the left and right sides higher than those on the front and rear sides. A pushing rack 425 is fixedly disposed on the upper end face of the connecting block. The upper end face is provided with a connecting groove that communicates with the corresponding telescopic groove. An L-shaped block 426 that is fixedly connected to the corresponding telescopic column 422 is slidably arranged in the connecting groove, and the other end of the L-shaped block 426 is fixedly connected to the corresponding push rack 425. A gear groove is provided on the upper end face of the center position of the mounting block 42. Four alignment holes 43 arranged in a matrix are provided on the upper end face of the mounting block 42. Alignment columns 430 are slidably arranged in the alignment holes 43. A cross member 431 is fixedly arranged on the upper end face of all alignment columns 430. A gear shaft 432 is rotatably arranged at the middle position of the cross member 431. A push gear 433 placed in the gear groove 43 is fixedly sleeved on the lower end area of ​​the gear shaft 432. The push gear 433 meshes with the push rack 425. A fixed gear 434 that is fixedly connected to the lower end face of the cross member 431 is provided on the gear shaft 432. The fixed gear 434 has the same shape as the push gear 433.

[0037] During operation, when the distance between two opposing arc-shaped plates 30 is too small to allow the corresponding support plate 32 to be moved down to the designated position for support via the operating bar 404, the mounting block 42 is first installed through the engagement between the limiting groove and the corresponding limiting post 421. Then, under the operation of the lifting cylinder 401, the operating bar 404 moves the mounting block 42 to the designated position. Subsequently, the external motor drives the corresponding push gear 433 to rotate via the gear shaft 432. At this time, the push gear 433, through its meshing with the corresponding push rack 425, causes the push rack 425 to move away from the push gear 433. Therefore, the push rack 425, via the corresponding L-shaped block 426, drives the telescopic post 422 towards the opposite direction. As the corresponding arc-shaped plate 30 moves, the telescopic column 422 moves into the mating groove. Under the continuous rotation of the pushing gear 433, the four telescopic columns 422 open the corresponding arc-shaped plate 30. Then, the cross member 431 moves downward and causes the cross member 431 to drive the pushing gear 433 to move into the gear groove. At this time, the fixed gear 434 meshes with all the pushing racks 425. Therefore, the pushing racks 425 are limited and fixed. That is, the telescopic column 422 maintains the support and fixation of the corresponding arc-shaped plate 30 through the mating groove. Then, the support plate 32 or the mating plate 33 is placed for support, avoiding the problem that the arc-shaped plates 30 cannot be supported due to the small distance between them, thus improving the applicability of the device.

[0038] See Figure 7 An auxiliary spring 44 is provided between the inner wall of the telescopic groove and the corresponding telescopic column 422.

[0039] During operation, when the telescopic column 422 is to be engaged with the corresponding mating groove, the mounting block 42 is first moved to the designated position. The external motor drives the engagement between the gear 433 and the corresponding rack 425, causing the telescopic column 422 to move away from the corresponding mating part 423. At this time, the corresponding auxiliary spring 44 is compressed. After the telescopic column 422 is aligned with the mating groove on the mating part 423, the external motor stops driving the gear 433 to rotate. Thus, the telescopic column 422 engages with the corresponding mating groove under the elastic force generated by the reset of the auxiliary spring 44, facilitating the rapid subsequent support operation.

[0040] See Figure 2The right end face of the lifting plate 11 is fixedly provided with a right placement plate 45. The right end face of the right placement plate 45 has two symmetrical downward sliding grooves 450 from top to bottom. A downward sliding block is slidably arranged in the downward sliding groove 450. A connecting column is fixedly provided on the upper end face of the downward sliding block. A circular plate 451 is fixedly arranged on the upper end face of the two connecting columns. A downward sliding cylinder 452 is fixedly arranged between the circular plate 451 and the right placement plate 45. A load-bearing plate 453 is fixedly arranged on the right end face of the downward sliding block. The load-bearing plate 453 has a right-angled trapezoidal structure on the right end. The opposite faces of the two load-bearing plates 453 are provided with right sliding grooves 454 from left to right. An electric slider is slidably arranged in the right sliding groove 454. A push plate 455 is fixedly arranged on the two electric sliders through the connecting columns.

[0041] After the internal support work of the arc-shaped plate 30 is completed, the collapsed area is manually treated again. Then, the walking component 2 moves the entire device to the left. During the movement, the downward cylinder 452 retracts its telescopic end, so the downward block moves the load-bearing plate 453 and the reinforced concrete slab placed on the load-bearing plate 453 to the designated height. At this time, the electric slider is activated, so the push plate 455 pushes the reinforced concrete slab to move and fall into the pre-cleared rectangular area, covering the collapsed area. Then, cement pouring and other operations are carried out manually around the reinforced concrete slab to improve the overall repair effect.

[0042] See Figure 2 The upper end face of the load-bearing plate 453 is provided with a plurality of rectangular grooves 46 arranged at equal intervals. The front and rear end faces of the inner wall of the rectangular grooves 46 are rotatably connected by a rotating shaft, and a placement roller 460 is fixedly sleeved on the rotating shaft.

[0043] During operation, the placement roller 460 is in close contact with the corresponding reinforced concrete slab. Therefore, when the push plate 455 pushes the reinforced concrete slab, the placement roller 460 reduces the friction between the load-bearing plate 453 and the reinforced concrete slab, which facilitates the pushing and placement operation of the push plate 455.

[0044] In practice, the collapsed area is first manually backfilled and repaired, forming a cylindrical pit. The area above is cleared and shaped to accommodate a reinforced concrete slab. Then, the curved slab 30 is manually placed inside the collapsed area, ensuring that its outer curved surface is flush with the inner wall of the collapsed area.

[0045] Then, the traveling component 2 moves the entire device above the collapsed area. The telescopic component 413 operates, causing the lifting plate 11 to move down to the designated position. Simultaneously, the lifting cylinder 401 operates, causing the operating plate 400 to move up and down via its telescopic end. This allows the lower end of the operating bar 404 on the operating plate 400 to move to the designated position. Before this, the support plate 32 is manually placed on the upper part of the corresponding two arc-shaped plates 30. Then, the operating bar 404 moves within the corresponding combination groove 402, and the cooperation between the four operating bars 404 limits and fixes the support plate 32 at this time. Afterward, the lifting cylinder 401 operates, causing the operating bar 404 to move down via its telescopic end. Thus, the operating bar 404, through the corresponding operating column 405, causes the support plate 32 to move down, thereby moving the support plate 32 down onto the corresponding placement plate 31 and providing support for the arc-shaped plate 30. Then, the corresponding mating plate 33 is placed in the same way.

[0046] Finally, after the internal support work of the arc plate 30 is completed, the collapsed area is manually processed again. Then, the walking component 2 moves the entire device to the left. During the movement, the downward cylinder 452 retracts its telescopic end, so the downward block moves the load-bearing plate 453 and the reinforced concrete slab placed on the load-bearing plate 453 to the designated height. At this time, the electric slider is activated, so the push plate 455 pushes the reinforced concrete slab to move and fall into the rectangular area that has been cleared in advance, and covers the collapsed area. Then, cement pouring and other operations are carried out manually around the reinforced concrete slab.

[0047] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
