Technical Field

[0001] This utility model relates to the field of mine roadway support technology, specifically a hydraulic support structure for narrow roadways. Background Technology

[0002] Mine roadways are underground passage networks formed during the mining process. They are mainly divided into three categories according to their service scope and purpose: development roadways, preparation roadways, and mining roadways. In order to keep mine roadways stable, hydraulic support structures are usually required.

[0003] A search revealed that the announcement number is CN214533007U, and the name is "A Support Structure for Mining Engineering Roadways, including a base". Through research and analysis, it was found that although it has the advantages of conveniently supporting roadways of different widths and facilitating the use of equipment, it also has the following disadvantages to a certain extent.

[0004] For example, during use, it is inconvenient to position the bottom of the device, making it difficult to keep the device stable. The top support position is fixed, making it difficult to support the top of the tunnel. The top of the tunnel is prone to collapse, which can easily cause accidents. In order to solve the above technical problems, we have designed a hydraulic support structure for narrow tunnels. Utility Model Content

[0005] The purpose of this utility model is to provide a hydraulic support structure for narrow tunnels, which has the advantage of convenient support and solves the problems of the device during use, such as difficulty in positioning the bottom, difficulty in maintaining the stability of the device, fixed top support position, difficulty in supporting the tunnel top, and easy collapse of the tunnel top, which can easily cause accidents.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a hydraulic support structure for narrow tunnels, comprising a mounting frame, a first hydraulic rod bolted to the top of the mounting frame, a support shell bolted to the top of the first hydraulic rod, a movable rod slidably connected to the inner cavity of the mounting frame, a connecting rod welded to the surface of the movable rod, a second hydraulic rod bolted to the top of the connecting rod, a first movable plate bolted to the top of the second hydraulic rod, a second movable plate welded to the bottom of the first movable plate, a third hydraulic rod bolted to the top of the mounting frame, a connecting plate bolted to the surface of the third hydraulic rod, a connecting plate welded to the bottom of the connecting plate and the connecting rod, a support column welded to the bottom of the connecting rod, a retaining shell bolted to the surface of the support column, a positioning plate welded to the surface of the support column, a movable component provided on the top of the positioning plate, and positioning pins inserted into the surface of the support column.

[0007] Preferably, the movable component includes a storage shell, the bottom of which is connected to a positioning plate, a threaded rod extending through the top of the storage shell, a movable plate rotatably connected to the bottom of the threaded rod, and casters bolted to the bottom of the movable plate.

[0008] Preferably, a reinforcing plate is welded to the front side of the support column, and the surface of the threaded rod is threadedly connected to the reinforcing plate.

[0009] Preferably, the top of the threaded rod is bolted to a handle, and the surface of the movable version is slidably connected to the storage shell.

[0010] Preferably, the opposite side of the first movable plate extends into the inner cavity of the support shell, and the surface of the support shell is slidably connected to the first movable plate.

[0011] Preferably, the bottom of the second movable plate extends into the inner cavity of the retaining shell, and the surface of the second movable plate is slidably connected to the retaining shell.

[0012] Preferably, a vertical plate is welded to the top of the mounting bracket, and the opposite side of the third hydraulic rod contacts the vertical plate.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] This utility model uses the telescopic movement of the third hydraulic rod to drive the connecting plate to move laterally, which in turn drives the connecting rod and the movable rod to move laterally. Then, the connecting rod drives the second hydraulic rod, the first movable plate, and the second movable plate to move laterally, adjusting the extension length of the first movable plate and expanding the support area. At the same time, the telescopic movement of the first and second hydraulic rods drives the support shell, the first movable plate, and the second movable plate to move up and down, so that the support shell and the first movable plate come into contact with the top of the tunnel.

[0015] This utility model positions the device by driving a positioning nail through the positioning plate into the ground, supports the top of the tunnel by the support shell and the first movable plate to prevent the top of the tunnel from collapsing, and supports the sides of the tunnel by the retaining shell and the second movable plate to prevent the sides of the tunnel from collapsing.

The bottom of the connecting plate 11 is welded to the connecting rod 6. A support column 13 is welded to the bottom of the connecting rod 6. A retaining shell 14 is bolted to the surface of the support column 13. A positioning plate 15 is welded to the surface of the support column 13. A movable component 21 is provided on the top of the positioning plate 15. Positioning nails 20 are inserted into the surface of the support column 13.

[0023] Please see Figure 1 and Figure 4 The movable component 21 includes a storage shell 16. By setting the storage shell 16, the movable version 18 and the casters 19 can be stored easily, and the device can be fixed easily. The bottom of the storage shell 16 is connected to the positioning plate 15, and a threaded rod 17 is provided through the top of the storage shell 16. The bottom of the threaded rod 17 is rotatably connected to the movable version 18, and the bottom of the movable version 18 is connected to the casters 19 by bolts. By setting the casters 19, the device can be supported easily, and the device can be moved stably.

[0024] Please see Figure 1 and Figure 4 A reinforcing plate 4 is welded to the front side of the support column 13. By setting the reinforcing plate 4, it is easy to position and reinforce the threaded rod 17, and it is easy to move the threaded rod 17 stably. The surface of the threaded rod 17 is threadedly connected to the reinforcing plate 4.

[0025] Please see Figure 1 and Figure 4 The top of the threaded rod 17 is connected to a handle by bolts. The handle makes it easy for workers to grip and rotate the threaded rod 17. The surface of the movable plate 18 is slidably connected to the storage shell 16. The movable plate 18 guides the caster wheel 19 and allows the caster wheel 19 to move up and down.

[0026] Please see Figure 1 and Figure 2 The first movable plate 8 extends to the inner cavity of the support shell 3 on the opposite side. The surface of the support shell 3 is slidably connected to the first movable plate 8. By setting the first movable plate 8, the top support area can be easily expanded, and the top of the roadway can be easily supported.

[0027] Please see Figure 1 and Figure 2 The bottom of the second movable plate 9 extends into the inner cavity of the retaining shell 14. The surface of the second movable plate 9 is slidably connected to the retaining shell 14. By setting the second movable plate 9, it is easy to move with the connecting rod 6 and to expand the support area on both sides.

[0028] Please see Figure 1 and Figure 3 A vertical plate 12 is welded to the top of the mounting bracket 1. By setting the vertical plate 12, it is easy to support and reinforce the third hydraulic rod 10, and to keep the third hydraulic rod 10 stable. The opposite side of the third hydraulic rod 10 is in contact with the vertical plate 12.

[0029] The first hydraulic rod 2, the second hydraulic rod 7, and the third hydraulic rod 10 are all model GYCD-110 / 750, indicating that the maximum supporting force is 110kN, the operating pressure is 720bar, the maximum supporting height is 1060mm, and the original height is 450mm.

[0030] In use, the device is controlled by an external controller and supported by casters 19. Pushing the device causes the casters 19 to roll and move it into the tunnel. The third hydraulic rod 10 extends and retracts, causing the connecting plate 11 to move laterally. The connecting plate 11 then causes the connecting rod 6 and movable rod 5 to move laterally. The connecting rod 6 then causes the second hydraulic rod 7, the first movable plate 8, and the second movable plate 9 to move laterally, adjusting the extension length of the first movable plate 8 to expand the support area. As the connecting rod 6 moves, it also drives the support column 13, positioning plate 15, storage shell 16, and movable plate 18. The omnidirectional wheel 19 moves laterally, while the first hydraulic rod 2 and the second hydraulic rod 7 extend and retract, causing the support shell 3, the first movable plate 8, and the second movable plate 9 to move up and down, so that the support shell 3 and the first movable plate 8 contact the top of the tunnel. After adjustment, the movable plate 18 and the omnidirectional wheel 19 are retracted into the storage shell 16 by rotating the threaded rod 17, so that the bottom of the positioning plate 15 contacts the ground of the tunnel. The positioning nail 20 is driven into the ground through the positioning plate 15 to position the device. The support shell 3 and the first movable plate 8 support the top of the tunnel to prevent the top of the tunnel from collapsing. The retaining shell 14 and the second movable plate 9 support the sides of the tunnel to prevent the sides of the tunnel from collapsing.

[0031] In summary, this hydraulic support structure for narrow tunnels, through the threaded rod 17, movable plate 18, casters 19, positioning pins 20, and movable components 21, solves the problems of the device being inconvenient to position at the bottom, difficult to maintain stability, and having a fixed top support position, making it difficult to support the tunnel roof and causing the tunnel roof to collapse and potentially lead to accidents.
