Problems solved by technology

[0002] The damper walls of mines are generally built with solid red bricks. When the mine is under pressure, the walls are easily damaged, and the damper frame is easily deformed, resulting in insensitive damper switches. Sometimes it cannot be opened or closed. When maintaining the damper On the one hand, it has caused a lot of waste of manpower and material resources, and it has also brought great potential safety hazards to mine ventilation.

Abstract

A suspended adjustable pressure-free air door comprises a door frame. The door frame is installed on a wall through transverse adjusting devices. The transverse adjusting devices can slide through transverse sliding holes arranged on the door frame. The door frame is connected with two door leaf bodies through up-and-down adjusting devices which can slide through longitudinal slide holes arranged on the two door leaf bodies. Seal blocks are arranged at the contact position of the two door leaf bodies. The suspended adjustable pressure-free air door has the advantages of effectively eliminating the damage, caused by the mine pressure, to the air door and avoiding the potential safety hazards brought to a mine when the mine pressure damages the air door.

Description

technical field [0001] The invention relates to mine equipment, in particular to a suspension adjustable non-pressure damper. Background technique [0002] The damper walls of mines are generally built with solid red bricks. When the mine is under pressure, the walls are easily damaged, and the damper frame is easily deformed, resulting in insensitive damper switches. Sometimes it cannot be opened or closed. When maintaining the damper On the one hand, it has caused a lot of waste of manpower and material resources, and has also brought great potential safety hazards to mine ventilation. SUMMARY OF THE INVENTION [0003] The object of the present invention is to provide a hanging adjustable non-pressure damper which effectively solves the damage to the damper by mine pressure and avoids the potential safety hazard caused by the mine pressure damage damper to the mine. [0004] To achieve the above object, the technical solution adopted in the present invention is: [000...
