Description

Technical Field

[0001] The invention relates to the field of coal mining, in particular to a pneumatic installation vehicle for a gas extraction pipe for a coal mine. Background Art

[0002] Coal is generally divided into underground coal mines and open-pit coal mines. When the coal seam is far from the surface, people generally choose to dig tunnels underground to mine coal. This is an underground coal mine. Gas is a colorless, odorless gas produced by physical and chemical reactions during coal formation, but sometimes you can smell an apple-like fragrance. This is because aromatic hydrocarbon gases are emitted at the same time as gas. Gas is insoluble 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. Therefore, when mining coal, it is necessary to extract the gas in time to ensure the safety of normal mining operations.

[0003] During underground operations, the pneumatic installation vehicle for gas extraction pipes for coal mines can perform the following operations: The pneumatic installation vehicle for gas extraction pipes for coal mines uses gas as power and does not contain electrical components. It is fully suitable for use in flammable and explosive gas environments underground in mines. Its excellent structural design allows it to work in narrow and complex tunnels, effectively improving installation efficiency, reducing the labor intensity of workers, reducing damage to the tunnel anchor net, and improving the safety of people and objects in the tunnel, ultimately making the overall operation more convenient.

[0004] Due to the limitation of the layout and size of the space in the tunnel, there is no equipment for installing gas extraction pipes in the coal mine market. The miners mainly rely on manual construction of platforms and installation with lifting hoists. The existing installation method requires frequent construction and dismantling of platforms and replacement of lifting hoists, which is inefficient. In addition, the lifting hoist needs to be installed on the top plate anchor net, which damages the anchor net, affects the stability of the tunnel surrounding rock, and threatens the safety of people and objects in the tunnel. Manually moving the gas extraction pipe weighing 130 to 200 kg is labor-intensive and has a certain adverse effect on the physical and mental health of employees. Therefore, we propose a pneumatic installation vehicle for gas extraction pipes in coal mines. Summary of the invention
