Description

Technical Field

[0001] This utility model relates to the field of retaining wall assembly technology, specifically to a high-strength flexible retaining wall for coal mine paste filling. Background Technology

[0002] In the coal mining sector, paste backfilling technology, as one of the core technologies of green mining, can effectively control roof subsidence in goaf areas, reduce surface collapse, and simultaneously realize the resource utilization of solid waste such as coal gangue. This is of great significance for ensuring safe coal mine production and ecological environmental protection. High-strength flexible retaining walls, as key support structures in paste backfilling operations, primarily function to delineate the backfilling area in the goaf, withstand the lateral pressure generated during paste backfilling, prevent paste leakage, and ensure that the backfill material can be formed according to design requirements and perform its supporting function.

[0003] In the process of using existing retaining walls, multiple retaining walls often need to be assembled. Adjacent retaining wall units are generally fixed by bolt connection. However, each retaining wall unit usually requires 4-6 bolt connection points. In the narrow working space of the goaf, multiple bolts need to be tightened in sequence to assemble the retaining wall, resulting in low assembly efficiency between retaining walls. Utility Model Content

[0004] This invention proposes a high-strength flexible retaining wall for coal mine paste filling, which solves the problem of low assembly efficiency between multiple retaining walls fixed by bolts in the prior art.

[0005] The technical solution of this utility model is as follows: a high-strength flexible retaining wall for coal mine paste filling, including a retaining wall body, an installation frame, a first positioning frame, a second positioning frame, and a positioning mechanism. Multiple installation frames are fixedly installed at the bottom of the side wall of the retaining wall body, and a first bolt is passed through each installation frame. Multiple first positioning frames are installed at one end of the side wall of the retaining wall body, and multiple second bolts are passed through between the first positioning frames and the retaining wall body. A second positioning frame is installed at the other end of the side wall of the retaining wall body, located on one side of the first positioning frames, and multiple third bolts are passed through between the second positioning frames and the retaining wall body. The positioning mechanism is installed on the first positioning frame and is used to install and fix the first positioning frame and the adjacent second positioning frame.

[0006] Preferably, the positioning mechanism includes a positioning port, a first housing, a fixed plate, a fixed block, a moving mechanism, and a position adjustment mechanism. The positioning port is opened on the second positioning frame, the first housing is fixedly mounted on the first positioning frame, and the shape of the first housing is adapted to the positioning port. The side wall of the first housing has multiple fixing ports. The fixed plate is slidably mounted along the axial direction of the first housing. The side wall of the fixed plate has a fixing groove on one side of the fixing port. The fixed block is slidably mounted in the fixing groove. The moving mechanism is mounted on the fixed plate and is used to drive the fixed plate to move within the first housing. The position adjustment mechanism is located between the fixed plate and the fixed block and is used to adjust the position of the fixed block.

[0007] Furthermore, the moving mechanism includes a threaded rod and a first handwheel. The threaded rod is rotatably disposed within the first housing and passes through the fixed disc via a threaded connection. The first handwheel is rotatably disposed on the side wall of the first housing and is fixedly connected to the threaded rod.

[0008] Furthermore, the position adjustment mechanism includes a first cavity, a first gear, an adjustment slot, a support spring, and a synchronous rotation mechanism. The fixed disk has an annular first cavity, and an adjustment port is formed between the first cavity and the fixed slot. The first gear is rotatably mounted on one side of the adjustment port within the first cavity. An adjustment disk is fixedly mounted on the side wall of the first gear, extending into the adjustment port. An adjustment column is rotatably mounted at an eccentric position on the adjustment disk. The adjustment slot is formed on the side wall of the fixed block, and the adjustment column extends into the adjustment slot. The support spring is fixedly mounted between the fixed slot and the fixed block. The synchronous rotation mechanism is mounted on the fixed disk and is used to drive multiple first gears to rotate synchronously.

[0009] Furthermore, the synchronous rotation mechanism includes a second gear, a first gear ring, and a drive mechanism. The second gear is rotatably disposed within the first cavity, and the first gear ring is rotatably disposed within the first cavity. The first gear ring meshes with both the first gear and the second gear. The drive mechanism is disposed on the fixed disk and is used to drive the second gear to rotate.

[0010] Based on the above scheme, the driving mechanism includes a first driving port, a second driving port, a driving prism, and a second handwheel. The first driving port is opened on the fixed plate, and the second driving port is opened on the second gear. The first driving port and the second driving port are aligned. The driving prism is rotatably disposed in the first housing and passes through the first driving port and the second driving port. The driving prism is slidably connected to the side wall of the second driving port. The second handwheel is rotatably disposed on the side wall of the first housing and is fixedly connected to the driving prism.

[0011] The working principle and beneficial effects of this utility model are as follows: 1. In this utility model, by setting up a position adjustment mechanism, after the first housing passes through the positioning port, the adjustment of multiple fixing blocks can be achieved by rotating the second handwheel, so that the fixing blocks extend out of the fixing port. At this time, the fixing between the first positioning frame and the second positioning frame can be achieved by cooperating with the second positioning frame and the fixing block, thereby facilitating the assembly of the retaining wall body. 2. In this utility model, by setting up a moving mechanism, the rotation of the first handwheel can drive the threaded rod to rotate, and at the same time, the threaded rod and the fixed plate are driven to move through the threaded engagement of the threaded rod and the fixed plate, thereby facilitating the fixed block to be pressed on the second positioning frame, thereby improving the installation stability of the first positioning frame and the second positioning frame, and thus improving the assembly stability between the retaining wall body.

[0015] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this utility model.

[0016] like Figures 1-5 As shown, this embodiment proposes a high-strength flexible retaining wall for coal mine paste filling, including a retaining wall body 1, an installation frame 2, a first positioning frame 4, a second positioning frame 6, and a positioning mechanism. Multiple installation frames 2 are fixedly installed at the bottom of the side wall of the retaining wall body 1, and first bolts 3 are passed through the installation frames 2. Multiple first positioning frames 4 are installed at one end of the side wall of the retaining wall body 1, and multiple second bolts 5 are passed through between the first positioning frames 4 and the retaining wall body 1. A second positioning frame 6 is installed at the other end of the side wall of the retaining wall body 1, located on one side of the first positioning frames 4, and multiple third bolts 7 are passed through between the second positioning frames 6 and the retaining wall body 1. The positioning mechanism is installed on the first positioning frames 4 and is used to install and fix the first positioning frames 4 and the adjacent second positioning frames 6.

[0017] Reference Figures 1-4The positioning mechanism includes a positioning port 8, a first housing 9, a fixing plate 11, a fixing block 12, a moving mechanism, and a position adjustment mechanism. The positioning port 8 is opened on the second positioning frame 6. The first housing 9 is fixedly mounted on the first positioning frame 4. The shape of the first housing 9 is adapted to the positioning port 8. The side wall of the first housing 9 has multiple fixing ports 10. The fixing plate 11 is slidably mounted along the axial direction of the first housing 9. The side wall of the fixing plate 11 has a fixing groove on one side of the fixing port 10. The fixing block 12 is slidably mounted in the fixing groove. The moving mechanism is mounted on the fixing plate 11 and is used to drive the fixing plate 11 to move within the first housing 9. The position adjustment mechanism is located between the fixing plate 11 and the fixing block 12 and is used to adjust the position of the fixing plate 11. The position of the fixed block 12 is adjusted. The moving mechanism includes a threaded rod 13 and a first handwheel 14. The threaded rod 13 is rotatably disposed inside the first housing 9 and passes through the fixed plate 11 through a threaded engagement. The first handwheel 14 is rotatably disposed on the side wall of the first housing 9 and is fixedly connected to the threaded rod 13. Specifically, after the operator inserts the first housing 9 through the positioning port 8, the fixed block 12 can be extended out of the fixing port 10 through the operation of the position adjustment mechanism. Then, the rotation of the first handwheel 14 can drive the threaded rod 13 to rotate. At the same time, the threaded engagement between the threaded rod 13 and the fixed plate 11 drives the fixed plate 11 and the fixed block 12 to move, thereby facilitating the pressing of the fixed block 12 onto the second positioning frame 6, and thus improving the assembly stability between the retaining wall bodies 1.

[0018] Reference Figures 2-5The position adjustment mechanism includes a first cavity 15, a first gear 16, an adjustment slot 19, a support spring 20, and a synchronous rotation mechanism. The fixed disk 11 has an annular first cavity 15. An adjustment port is formed between the first cavity 15 and the fixed slot. The first gear 16 is rotatably mounted on one side of the adjustment port within the first cavity 15. An adjustment disk 17 is fixedly mounted on the side wall of the first gear 16, extending into the adjustment port. An adjustment column 18 is rotatably mounted at an eccentric position on the adjustment disk 17. The adjustment slot 19 is formed on the side wall of the fixed block 12. The adjusting column 18 extends into the adjusting channel 19. The supporting spring 20 is fixedly disposed between the fixed groove and the fixed block 12. The synchronous rotation mechanism is disposed on the fixed disk 11 and is used to drive multiple first gears 16 to rotate synchronously. Specifically, the operation of the synchronous rotation mechanism can drive multiple first gears 16 to rotate synchronously. At the same time, the rotation of the first gears 16 can drive the adjusting disk 17 to rotate, causing the adjusting column 18 to move around the adjusting disk 17. During the movement of the adjusting column 18, the position of the fixed block 12 can be adjusted by the squeezing of the adjusting column 18 against the side wall of the adjusting channel 19.

[0019] Reference Figures 2-5 The synchronous rotation mechanism includes a second gear 21, a first gear ring 22, and a drive mechanism. The second gear 21 is rotatably disposed within the first cavity 15, and the first gear ring 22 is rotatably disposed within the first cavity 15. The first gear ring 22 meshes with the first gear 16 and the second gear 21, respectively. The drive mechanism is disposed on the fixed disk 11 and is used to drive the second gear 21 to rotate. The drive mechanism includes a first drive port 23, a second drive port, a drive prism 24, and a second handwheel 25. The first drive port 23 is located on the fixed disk 11, and the second drive port is located on the second gear 21. The first drive port 23 and the second drive port are aligned. The driving prism 24 is rotatably disposed within the first housing 9, passing through the first driving port 23 and the second driving port. The driving prism 24 is slidably connected to the side wall of the second driving port. The second handwheel 25 is rotatably disposed on the side wall of the first housing 9, and is fixedly connected to the driving prism 24. Specifically, the rotation of the second handwheel 25 can drive the driving prism 24 to rotate, and at the same time, the sliding engagement between the driving prism 24 and the side wall of the second driving port drives the second gear 21 to rotate. Simultaneously, the meshing of the second gear 21 with the first gear ring 22 and the meshing of the first gear ring 22 with the first gear 16 drives multiple first gears 16 to rotate.

[0020] In this embodiment, during use, the operator fixes the first positioning frame 4 and the second positioning frame 6 to the side wall of the retaining wall body 1 by rotating the second bolt 5 and the third bolt 7. Then, the operator rotates the second handwheel 25. The rotation of the second handwheel 25 can drive the drive prism 24 to rotate. At the same time, the sliding engagement between the drive prism 24 and the side wall of the second drive port drives the second gear 21 to rotate. Simultaneously, the meshing of the second gear 21 with the first gear ring 22 and the meshing of the first gear ring 22 with the first gear 16 drives multiple first gears 16 to rotate. The rotation of the first gears 16 can drive the adjustment plate 17 to rotate, causing the adjustment column 18 to move around the adjustment plate 17. During the movement of the adjustment column 18... During the process, the adjusting column 18 can press against the side wall of the adjusting groove 19, causing the fixing block 12 to retract into the fixing groove. Then, the operator can move the retaining wall body 1 so that the first housing 9 on the first positioning frame 4 passes through the adjacent positioning port 8 and opens the second handwheel 25. Under the elastic force of the support spring 20, the fixing block 12 can extend out of the fixing port 10. The operator then rotates the first handwheel 14, which rotates the threaded rod 13. Simultaneously, the threaded engagement between the threaded rod 13 and the fixing plate 11 moves the fixing plate 11 and the fixing block 12, facilitating the pressing of the fixing block 12 onto the second positioning frame 6, thereby improving the assembly stability between the retaining wall bodies 1. Afterwards, the operator can rotate the first bolt 3 to fix the mounting frame 2 to the ground, thus securing multiple retaining wall bodies 1.

[0021] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
