Coal mine double-layer translation self-control ventilation door device

Abstract

A coal mine double-layer translation self-control ventilation door device belongs to a coal mine underground tunnel door, and more particularly relates to a tunnel ventilation and tunnel security passdoor which is controlled to open four main-auxiliary double-layer translation self-control ventilation doors. The coal mine double-layer translation self-control ventilation door device comprises anelectric control part, a door leaf moving part, a main transmission part and a traction transmission part and consists of an explosion-proof motor, a sound-light alarm, a guide pulley, a sealing bar,a door post, a main door leaf, an auxiliary door leaf, a door leaf lower guide pulley, a main door leaf upper guide pulley guide groove, a main transmission wire rope, a main door leaf lower pulley guide rail, a protection cover and a stopper. The device has flexible start operation of the main-auxiliary doors, good sealing and convenient automation control and operation; and the invention discards a lower gliding rail, and provides an indispensable device for a modernized mine and capable of effectively controlling and adjusting the tunnel ventilation and tunnel security pass door for the coal mine underground.

Description

Technical field: [0001] The utility model relates to a double-layer translational self-control damper device for a coal mine, which is an underground coal mine roadway door, and particularly relates to roadway ventilation and safe passage control and adjustment of four main and auxiliary suspension-mounted translational double-layer self-control dampers. Background technique: [0002] As we all know, gas is easy to accumulate in underground tunnels of coal mines, and underground explosion accidents occur from time to time. It is very important to control and adjust the safety, smoothness and ventilation of tunnels to ensure safe production in coal mines; The glideslope is manually opened and closed, labor-intensive, and some hydraulically controlled damper devices are used. The process is complicated, it takes up a lot of space, it is difficult to operate, there are many accidents, and the ventilation and traffic of the roadway are restricted to varying degrees.

[0002] As we all know, gas is easy to accumulate in underground tunnels of coal mines, and underground explosion accidents occur from time to time. It is very important to control and adjust the safety, smoothness and ventilation of tunnels to ensure safe production in coal mines; The glide path is manually opened and closed, labor-intensive, and some hydraulically controlled air door devices are used. The process is complicated, the space is large, the operation is difficult, there are many accidents, and the ventilation and traffic of the roadway are restricted to varying degrees.
