Technical Field

[0001] This utility model relates to the field of tunnel support technology, specifically to a support structure for controlling the surrounding rock of a mine tunnel in geological conditions. Background Technology

[0002] The mine roadway support structure is a crucial part of mining operations. Its main function is to support the mine roadways, prevent the collapse of rock strata, and thus ensure the safety of miners and the smooth progress of mining operations.

[0003] In mine roadway support systems, steel frame support structures are commonly used to ensure the stability and safety of the roadways. A steel frame typically consists of several individual support frames, which are installed and connected to form a continuous support system. However, in practical applications, gaps often appear between the steel frame support structures. These gaps affect the continuity of the support structure, leading to insufficient support in some areas, particularly the sidewalls of the roadway, which cannot be effectively supported. Therefore, improvements are needed. Summary of the Invention

[0025] To further understand the content of this utility model, a detailed description of this utility model will be provided in conjunction with the accompanying drawings and embodiments. It should be understood that the embodiments are merely illustrative of this utility model and are not intended to limit it.

[0026] The following is in conjunction with the appendix Figures 1-7 This embodiment will be described in further detail.

[0027] Please see Figures 1-7 This embodiment of a mine underground roadway surrounding rock control support structure includes an arc-shaped roof plate 100, vertical blocks 101 are provided opposite to each other on both sides of the bottom of the arc-shaped roof plate 100, clamping plates 102 are provided opposite to each other on both sides of the vertical blocks 101, a clamping groove 103 is formed between the clamping plates 102, a protective plate 104 for strengthening the roadway sidewall support is provided in the clamping groove 103, a fixing component for fixing the protective plate 104 is provided on the clamping plate 102, a lifting component for driving the arc-shaped roof plate 100 to rise and fall is provided in the vertical blocks 101, and an installation component for installing the arc-shaped roof plate 100 is provided between the arc-shaped roof plate 100 and the vertical blocks 101.

[0028] In this embodiment, the four corners of the guard plate 104 can be placed in the grooves 103 between the clamping plates 102, and the guard plate 104 is fixed by the fixing components, so that the guard plate 104 is fixedly installed between adjacent vertical blocks 101, thereby supporting the roadway sidewall between the vertical blocks 101, thus solving the problem that the continuity of the support structure is affected by the interval and the roadway sidewall cannot be effectively supported.

[0029] In this embodiment, the arc-shaped top plate 100 can be detachably installed on the vertical block 101 by means of the installation component, and the installation and removal are relatively convenient, which facilitates the maintenance and replacement of the arc-shaped top plate 100 and makes it convenient for construction personnel to carry out construction.

[0030] In this embodiment, the height of the arc-shaped top plate 100 can be appropriately adjusted by the lifting component so that the height of the arc-shaped top plate 100 can be adapted to the height of the tunnel and better fit the top wall of the tunnel.

[0031] Please see Figures 1-7 The upper and lower ends of the two sides of the guard plate 104 are respectively provided with connecting blocks 200 that can be inserted into the clamping groove 103. The fixing component includes a clamping piece 201 provided in the clamping groove 103, and a threaded rod 202 that is threadedly connected to the clamping piece 201 is provided between the clamping plates 102.

[0032] In this embodiment, the connecting block 200 is fixedly connected to the guard plate 104, and the threaded rod 202 is installed between the clamping plates 102 through bearings. When installing the guard plate 104, the guard plate 104 is lifted so that the height of the upper connecting block 200 exceeds the height of the upper clamping plate 102. Then, the upper connecting block 200 is inserted into the clamping groove 103, and at the same time, the lower connecting block 200 is also inserted into the clamping groove 103. The threaded rod 202 is rotated so that the clamping piece 201 moves to clamp the guard plate 104.

[0033] In this embodiment, after the guard plate 104 is pre-fixed by the clamping groove 103, the guard plate 104 has a corresponding thickness so that the back side of the guard plate 104 can fit against the side wall of the roadway. When the threaded rod 202 is rotated to fix the guard plate 104, the clamping piece 201 squeezes the guard plate 104, which enables the guard plate 104 to better support the roadway.

[0034] Specifically, in actual use, one side wall of the clamp 201 is attached to the side wall of the vertical block 101 to restrict the clamp 201 so that it cannot rotate circumferentially, thereby allowing the rotation of the threaded rod 202 to drive the clamp 201 to press against the guard plate 104.

[0035] In this embodiment, the arc-shaped top plate 100, the vertical plate and the guard plate 104 can all be disassembled and assembled individually, which improves the flexibility of the device, facilitates the maintenance and replacement of the device, and also facilitates the transportation and construction by construction personnel.

[0037] In this embodiment, the support block 301 is slidably connected to the upper groove 300, the lifting block 303 is fixedly connected to the support block 301, the lifting block 303 is slidably connected to the lifting groove 302, and the bottom end of the support rod 304 is fixedly connected to the lifting block 303. When it is necessary to adjust the height of the arc-shaped top plate 100 to fit against the top wall of the tunnel, the support block 301 can be moved upward by the jack 306, the support block 301 can be moved upward by the support block 301, the lifting block 303 can be moved upward by the lifting block 303, and the support rod 304 can be moved upward by the lifting block 303, thereby moving the arc-shaped top plate 100 upward to fit against the top wall of the tunnel.

[0038] Please see Figures 1-7 The mounting assembly includes a plug 400 mounted on a support rod 304, a locking hole 401 on the plug 400, a plug hole 402 at the bottom of the arc-shaped top plate 100 that mates with the plug 400, and mounting posts 403 at opposite ends of the inner side of the arc-shaped top plate 100. Each mounting post 403 has a circular cavity with one end open, and a locking rod 404 that can extend into or disengage from the corresponding locking hole 401 is provided in the circular cavity.

[0039] In this embodiment, the insert block 400 is fixedly connected to the support rod 304, the mounting post 403 is fixedly connected to the arc-shaped top plate 100, and the locking rod 404 penetrates the bottom wall of the circular cavity and extends into the insertion hole 402. When the arc-shaped top plate 100 is installed, the insert block 400 is inserted into the insertion hole 402, and the locking rod 404 is inserted into or removed from the locking hole 401 by the extension and retraction of the locking rod 404, so that the arc-shaped top plate 100 can be disassembled and assembled.

[0040] In this embodiment, the keyhole 401 can be shaped as a rectangular slot so that the lock rod 404 can be better inserted into the keyhole 401.

[0041] Please see Figures 1-7 A push block 405 is provided on the surface of the locking rod 404 located in the circular cavity. A plug 406 is provided at the opening end of the circular cavity. A spring 407 is sleeved on the locking rod 404 between the plug 406 and the push block 405. One end of the locking rod 404 extends through the plug 406. A pull plate 408 is provided at the end of the locking rod 404 that extends through the plug 406.

[0042] In this embodiment, the push block 405 is fixedly connected to the locking rod 404, and the plug cap 406 is threadedly connected to the open end of the circular cavity to install the components inside the circular cavity. The spring 407 is used to push the push block 405 to drive the locking rod 404 into the lock hole 401 to lock the arc-shaped top plate 100. The pull plate 408 is fixedly connected to the locking rod 404. Pulling the pull plate 408 can disengage the locking rod 404 from the lock hole 401 and release the locking of the arc-shaped top plate 100.

[0043] In use, when supporting the tunnel between the vertical blocks 101, the protective plate 104 is raised so that the height of the upper connecting block 200 exceeds the height of the upper clamping plate 102. Then, the upper connecting block 200 is inserted into the clamping groove 103, and at the same time, the lower connecting block 200 is also inserted into the clamping groove 103. The threaded rod 202 is rotated so that the clamping piece 201 moves to clamp the protective plate 104, thus enabling the protective plate 104 to be installed between adjacent vertical blocks 101.

[0044] In summary, the above description is only a preferred embodiment of the present utility model. All equivalent changes and modifications made within the scope of the patent application of the present utility model shall fall within the scope of the patent of the present utility model.
