Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of coal mine air door auxiliary tools, in particular to an anti-deformation device for an underground coal mine air door. Background Art
[0002] The damper is an important structure in the mine ventilation system. It is used to block the wind flow, create conditions for the distribution of mine wind flow on demand, and provide convenience for pedestrians and transportation. It is one of the most important components to ensure ventilation safety underground. It is used to block the wind flow in the tunnel or limit the wind volume passing through the tunnel, ensure the wind volume requirements of the places where wind is needed, and enable people and vehicles to pass through.
[0003] At present, conventional dampers are installed in tunnels as frame connections, and most of the outer frames are hard connections. When installed in high-ground pressure tunnels, if the underground coal and rock fragments expand and deform severely, it is easy to cause serious pressure on the existing ventilation facilities and a large amount of tunnel deformation. After the tunnel is deformed, it will compress the outer frame of the damper. After the outer frame is compressed and deformed, the door structure will deform, resulting in the damper being unable to open and close, posing a major safety hazard. Now some dampers will use some elastic buffer mechanisms to resist deformation, but generally these structures have limited anti-deformation capabilities. If the staff fails to discover the deformation here in time and does not take any measures, the damper will still be unable to open after the subsequent tunnel deformation intensifies.
