Technical Field
[0001] The utility model relates to the field of tunnel support, and more specifically, to a mining tunnel support structure. Background Art
[0002] For deep buried mines or open-pit mines when they are mined to a certain depth, underground mining methods must be used. At this time, various passages must be drilled between the surface and the ore body. For deep buried mines or open-pit mines when they are mined to a certain depth, underground mining methods must be used. At this time, various passages must be drilled between the surface and the ore body to transport ore, ventilation, drainage, pedestrians, and various necessary preparatory projects for newly excavated ore for metallurgical equipment. These passages are collectively called mine tunnels.

[0030] Example:
[0031] See also Figure 1-5 A mining tunnel support structure includes a base 1 and a mounting plate 15. A support plate 22 is slidably connected to the top of the mounting plate 15. A fixed block 17 is fixedly connected to the outside of the mounting plate 15. A sliding rod 18 is slidably connected to the inside of the fixed block 17. One end of the sliding rod 18 is fixedly connected to a limiting block 19. A limiting hole 23 is provided below the support plate 22. The limiting block 19 is clamped in the inside of the limiting hole 23. A spring 2 is sleeved on the outer wall of the sliding rod 18. The spring 2 is located inside the fixed block 17. One end of the sliding rod 18 located outside the fixed block 17 is rotatably connected to a handle 21. A rounded corner is provided on one side of the handle 21. In this solution, if the staff needs to adjust the base 1 and the support plate 22, the staff can rotate the handle 21 along the direction of the chamfer of the handle 21. After being rotated, the handle 21 will pull the sliding rod 18, and the sliding rod 18 will drive the limit block 19 to disengage from the inside of the limit hole 23 after being pulled. In this process, the limit block 19 will squeeze the spring 2, and the spring 2 will elastically deform and shrink after being squeezed by the limit block 19. When the handle 21 is rotated 90 degrees, the limit block 19 is completely disengaged from the inside of the limit hole 23. Through the elastic deformation of the spring 2, a tension can be applied between the limit block 19 and the handle 21, so that the handle 21 will not loosen after being rotated 90 degrees.
[0032] See also Figure 1-5 A threaded rod 11 is rotatably connected to the top of the base 1, and the threads on both sides of the threaded rod 11 are in opposite directions. A limit rod 12 is fixedly connected to the top of the base 1, and the limit rod 12 is located below the threaded rod 11. In this solution, the limit rod 12 is installed below the threaded rod 11.
[0033] See also Figure 1-5 The outer wall of the threaded rod 11 is threadedly connected with a moving block 13, and the moving block 13 is slidingly connected to the limit rod 12. In this solution, when the threaded rod 11 rotates, the moving blocks 13 threadedly connected on both sides of the threaded rod 11 will slide on the outer wall of the limit rod 12.
[0034] See also Figure 1-5 A turning handle 25 is rotatably connected to the top of the base 1, and a bevel gear 24 is fixedly connected to one side of the turning handle 25 and the middle of the threaded rod 11. The two bevel gears 24 are engaged. In this solution, the staff can shake the turning handle 25. Through the engagement between the two bevel gears 24, the turning handle 25 will drive the threaded rod 11 to rotate after it is rotated.
[0035] See also Figure 1-5 The outside of the moving block 13 is rotatably connected to a support rod 14, and the end of the support rod 14 away from the moving block 13 is rotatably connected to the bottom of the mounting plate 15. In this solution, when the two moving blocks 13 approach each other, they will push the mounting plate 15 to move upward.
[0036] See also Figure 1-5 A connecting rod 16 is fixedly connected to the bottom of the mounting plate 15, and the connecting rod 16 is slidably connected to the inside of the base 1. In this solution, when the mounting plate 15 moves upward, the connecting rod 16 will slide inside the base 1.
[0037] Working principle: If the device needs to be placed in the tunnel, the staff can first turn the handle 25, adjust the mounting plate 15 to the required height, insert the support plate 22 along the corresponding slide groove above the mounting plate 15, and then turn the rear handle 21 to clamp the limit block 19 into the inside of the limit hole 23.
[0038] The above description is merely a preferred embodiment of the present invention; however, the scope of protection of the present invention is not limited thereto. Any person skilled in the art who, within the technical scope disclosed in the present invention, makes equivalent substitutions or modifications based on the technical solutions and improved concepts of the present invention shall be covered by the scope of protection of the present invention.
