Description

Technical Field

[0001] The invention relates to a gas extraction device with an anti-hole collapse function, belonging to the technical field of tunnel support. Background Art

[0002] Gas is formed when cellulose and organic matter are decomposed by anaerobic bacteria in the early stage of ancient plants' accumulation into coal. In a high temperature and high pressure environment, while coal is being formed, gas continues to be generated due to physical and chemical reactions. Gas is a colorless and odorless gas, but sometimes you can smell an apple-like fragrance. This is because aromatic hydrocarbon gases are released at the same time as gas. The relative density of gas to air is 0.554. Under standard conditions, the density of gas is 0.716kg / m 3 The permeability of gas is 1.6 times that of air. It is difficult to dissolve in water, does not support combustion and cannot maintain breathing. When it reaches a certain concentration, it can cause people to suffocate due to lack of oxygen, and can cause combustion or explosion. Gas exists in the coal body or surrounding rock in a free state and an adsorbed state. Tunnels are various passages drilled between the surface and the ore body, which are used for ore transportation, ventilation, drainage, pedestrians, and various necessary preparatory projects for metallurgical equipment to mine ore. These passages are collectively referred to as tunnels.

[0028] When the present invention is in use,

[0029] Embodiment 1

[0030] The user can first rotate the rotating disc 16, which can drive the threaded rod 15 to rotate. Therefore, one end of the threaded rod 15 can rotate on the rotating shaft 14. When the threaded rod 15 spirally descends, under the limitation of the first groove, the linkage plate 12 can be lowered. When the linkage plate 12 is lowered, it can drive the stabilizing nail 13 to descend. Therefore, the stabilizing nail 13 can be inserted into the soil in the roadway, and thus the present invention can be stabilized. Then the user can rotate the plug plate 7, which can drive the rotating rod 6 to rotate. Therefore, the plug plate 7 can release the limitation on the side guard plate 5. Then the user can make the side guard plate 5 rotate through the connecting hinge. Therefore, the side guard plate 5 can be attached to the side of the roadway. When the side guard plate 5 rotates, the semi-circular plate 10 can be disengaged from the semi-circular groove 9. After that, the user can energize the first motor 19 to work and drive the rotating plate 20 to rotate. When the rotating plate 20 rotates 90 degrees, it can stop. Finally, the user can rotate the fixing bolt 23 to release the limitation on the extension plate 21. Then the user can pull the circular fixing plate 22, so that the extension plate 21 can move in the second groove. When one end of the circular fixing plate 22 passes through the fixing groove 11 on the semi-circular plate 10, it can stop. After that, the user can operate the fixing bolt 23 again to fix the extension plate 21. Therefore, the circular fixing plate 22 can be limited. Through the circular fixing plate 22, the side guard plate 5 can be limited to prevent the side guard plate 5 from rotating back. When the side of the roadway collapses, the side guard plate 5 can block the collapsed soil, so that the collapsed soil can be prevented from sliding into the roadway and affecting the walking of workers and equipment.

[0031] Embodiment 2

[0032] The user can install multiple of the present inventions in the roadway. When installing the gas pipeline, since the gas pipeline needs to be installed horizontally during installation to facilitate the docking of the gas pipeline, during installation, the user can energize the third motor 33 to work and drive the transmission screw rod 34 to rotate, so as to drive the sliding plate 26 to slide in the sliding groove. Therefore, the linkage block 27 can be raised and lowered, which facilitates maintaining a horizontal level with other installation mechanisms, and thus facilitates the horizontal installation of the gas pipeline. Then the user can place the gas pipeline to be installed on one side of the moving plate 29. Different-sized gas pipelines can be installed through the first fixing hole and the second fixing hole. When the user needs to use the second fixing hole, the user can energize the second motor 31 to work and drive the second gear 32 to rotate, so as to drive the first gear 30 and the bidirectional thread to rotate. When the bidirectional screw rod 28 rotates, under the limitation of the third groove, the moving plate 29 can be moved. Therefore, the gas pipeline can be installed through the second fixing hole. In summary, the installation of the gas pipeline is realized, and the collapse of the side of the roadway is prevented.
