Description

Technical Field

[0001] This utility model relates to the field of shaft support structure technology, and in particular to a shaft support structure for mine production. Background Technology

[0002] Mine production shaft support structure is a type of equipment used in underground mines or roadways. Its main function is to support and reinforce the shaft walls to ensure the safe and stable operation of the mine.

[0003] Publication No. CN208669328U discloses a mine support structure, including a support bracket and an L-shaped base. A T-shaped groove is provided on the upper inner side of the base's vertical wall. A T-shaped protrusion is provided on the outer side of the support leg of the support bracket, engaging with the T-shaped groove. An upwardly extending column is provided at the center of the base's bottom wall. Several support plates are strung on the column. Each support plate includes several standard support plates and a variable-thickness support plate. Vertical holes are provided at the centers of the standard and variable-thickness support plates to engage with the column. The variable-thickness support plate is located above the standard support plates and has at least two support parts of different thicknesses for supporting the support leg of the support bracket. However, traditional mine shaft support structures are usually of fixed height and cannot be adjusted according to different geological conditions. When geological characteristics are uneven, with height variations or interlayers, traditional support structures struggle to adapt to these changes, potentially leading to insufficient support or material waste. Therefore, improvements are needed. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a shaft support structure for mine production.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a shaft support structure for mine production, comprising a support column and a support crossbar, wherein the support crossbar is disposed at the top of the support column, and an adjusting support rod is provided through the top of the support column. An annular block A is fixedly installed at the bottom of the support column, and a threaded rotating rod is installed at the top of the annular block A. A threaded groove is provided in the middle of the interior of the adjusting support rod, and a bevel gear A is fixedly installed at the bottom of the threaded rotating rod. A bevel gear B is provided on one side of the bottom of the bevel gear A, and a straight rod is fixedly installed at one end of the bevel gear B. A handle is fixedly installed at one end of the straight rod, and an annular block B is fixedly installed inside the support column near the position of the straight rod.

[0006] Furthermore, the support crossbar is fixedly installed with the adjusting support rod, and the threaded rotating rod is threadedly connected to the threaded groove. Accordingly, in order for the rotation of the threaded rotating rod to drive the adjusting rod upward, thereby causing the support crossbar to abut against the top of the mine interior.

[0007] Furthermore, a limiting block is fixedly installed on the surface of the adjusting support rod, and a limiting groove is formed on the inner wall of the support column near the limiting block, with the limiting groove and the limiting block being slidably connected. Accordingly, in order to limit the movement trajectory of the adjusting support rod, the phenomenon of the adjusting support rod rotating due to the rotation of the threaded rod is avoided.

[0008] Furthermore, a bearing is provided at the intersection of the annular block A and the threaded rod. The outer shaft of the bearing is fixedly installed between the annular block A and the inner shaft of the bearing is fixedly installed between the threaded rod. This ensures that the threaded rod always rotates in place.

[0009] Furthermore, the bevel gear A and bevel gear B mesh with each other, and the annular block B is rotatably connected to the straight rod. Therefore, the rotation of bevel gear B can drive the rotation of bevel gear A.

[0010] Furthermore, a fixing mechanism is provided at the bottom end of the support base. The fixing mechanism includes a fixing frame, which is fixedly installed at the bottom end of the support base. An mounting plate is fixedly installed in the middle of the bottom end of the fixing frame. Anti-slip grooves are provided at the bottom ends of both the mounting plate and the fixing frame. Limiting holes are provided at the four corners of the top end of the fixing frame, and threaded drill rods are provided through the top ends of the limiting holes. Accordingly, the support base is more securely fixed.

[0011] Furthermore, the threaded drill rod is threadedly connected to the limiting hole, the anti-slip grooves are evenly arranged at the bottom of the mounting plate and the fixing frame, and a hexagonal block is fixedly installed at the top of the threaded drill rod. This facilitates the limiting and rotation of the threaded drill rod.

[0012] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0013] 1. In this utility model, by adjusting the setting of the support rod and the threaded rotating rod, the rotation of the threaded rotating rod can drive the adjustment support rod to move up and down, thereby adjusting the height of the support crossbar to adapt to different geological conditions. It can provide higher safety and flexibility under different geological conditions, reduce the risk of insufficient support, reduce material waste, and improve the efficiency and sustainability of mine production. In addition, the adjustable height also reduces maintenance costs because the shaft support structure can more easily adapt to geological changes.

[0014] 2. In this utility model, by setting multiple threaded drill rods, fixing frames, mounting plates and limiting holes, the well support structure can be moved downward along the limiting holes by the threaded drill rods when in use, until the threaded drill rods are drilled into the ground, so that the well support structure is fixed and the well support structure is more firmly fixed.

[0024] Example 1

[0025] Please see Figure 1-5This utility model provides a technical solution: a shaft support structure for mine production, including a support column 1 and a support crossbar 3. The support crossbar 3 is located at the top of the support column 1. An adjusting support rod 2 is installed through the top of the support column 1. A limiting block 19 is fixedly installed on the surface of the adjusting support rod 2. A limiting groove 20 is opened on the inner wall of the support column 1 near the limiting block 19. The limiting groove 20 and the limiting block 19 are slidably connected. The support crossbar 3 is fixedly installed with the adjusting support rod 2. A threaded rotating rod 10 is threadedly connected with a threaded groove 11. An annular block A13 is fixedly installed at the bottom of the support column 1. A threaded rotating rod 10 is installed at the top of the annular block A13. A bearing 12 is provided at the intersection of the annular block A13 and the threaded rotating rod 10. The outer shaft of the bearing 12 is fixedly installed with the annular block A13, and the inner shaft of the bearing 12 is fixedly installed with the threaded rotating rod 10. A threaded groove 11 is opened in the middle of the interior of the adjusting support rod 2. A bevel gear A14 is fixedly installed at the bottom of the support column 1. A bevel gear B15 is provided on one side of the bottom of the bevel gear A14. A straight rod 17 is fixedly installed at one end of the bevel gear B15. A handle 18 is fixedly installed at one end of the straight rod 17. An annular block B16 is fixedly installed inside the support column 1 near the straight rod 17. The bevel gear A14 and the bevel gear B15 mesh with each other. The annular block B16 is rotatably connected to the straight rod 17. The design of the adjustable support rod 2 and the threaded rotating rod 10 is to enable the rotation of the threaded rotating rod 10 to drive the adjustable support rod 2 to move up and down, thereby adjusting the height of the support crossbar 3 to adapt to different strata conditions. It can provide higher safety and flexibility under different strata conditions, reduce the risk of insufficient support, reduce material waste, and improve the efficiency and sustainability of mine production. In addition, the adjustable height also reduces maintenance costs because the shaft support structure can more easily adapt to strata changes.

[0026] Example 2

[0027] Please see Figure 1-2 The bottom of the support base 4 is provided with a fixing mechanism, which includes a fixing frame 6. The fixing frame 6 is fixedly installed at the bottom of the support base 4. A mounting plate 9 is fixedly installed in the middle of the bottom of the fixing frame 6. Anti-slip grooves 8 are opened at the bottom of both the mounting plate 9 and the fixing frame 6. Limiting holes 7 are opened at the four corners of the top of the fixing frame 6. A threaded drill rod 5 is inserted through the top of the limiting hole 7. The threaded drill rod 5 is threadedly connected to the limiting hole 7. The anti-slip grooves 8 are evenly arranged at the bottom of the mounting plate 9 and the fixing frame 6. A hexagonal block is fixedly installed at the top of the threaded drill rod 5. The design of multiple threaded drill rods 5, fixing frame 6, mounting plate 9 and limiting holes 7 is to enable the well support structure to move downward along the limiting holes 7 through the threaded drill rods 5 when in use, until the threaded drill rod 5 drills into the ground, so that the well support structure is fixed and the well support structure is more firmly fixed.

[0028] Working principle: When using the shaft support structure, first place the shaft support structure inside the mine shaft that needs support. Then, use a wrench to turn the hexagonal block. The rotation of the hexagonal block drives the threaded drill rod 5 to rotate and move downwards until the threaded drill rod 5 drills into the ground, thus fixing the shaft support structure. Then, simultaneously rotate the handle 18 on both side support columns 1. The rotation of the handle 18 drives the straight rod 17 to rotate, and the rotation of the straight rod 17 drives the bevel gear B15 to rotate. Because the bevel gear B15 meshes with the bevel gear A14, the bevel gear... The rotation of wheel B15 drives the bevel gear A14 to rotate, and the rotation of bevel gear A14 drives the threaded rod 10 to rotate. Due to the influence of bearing 12, the threaded rod 10 always rotates in place. Because the threaded rod 10 is threadedly connected to the threaded groove 11, and because the limiting block 19 and the limiting groove 20 limit the adjusting support rod 2, the rotation of the threaded rod drives the adjusting support rod 2 to move upward. The movement of the adjusting support rod 2 drives the support crossbar 3 to move until the support crossbar 3 moves to the top of the mine, thus providing support for the inside of the mine.

[0029] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
