Abstract

The invention discloses an air door opening and closing device, which comprises a first connecting rod, a second connecting rod, an air cylinder and an air channel control unit, wherein one end of the first connecting rod is hinged to a door leaf arranged in a mine tunnel, and the other end of the first connecting rod is hinged to one end of the second connecting rod; and the other end of the second connecting rod is hinged to a telescopic link of the air cylinder, a stationary shaft is arranged on the second connecting rod, and when the telescopic link of the air cylinder stretches or contracts under the control of the air channel control unit, the second connecting rod rotates around the stationary shaft under the driving of the telescopic link of the air cylinder and drives the first connecting rod to move so as to open or close the door leaf. With the air door opening and closing device, automatic opening and closing of the door leaf of an air door can be realized, so that the technical problem that the air door cannot be quickly and conveniently opened and closed in the prior art is solved.

Description

technical field [0001] The invention relates to mine ventilation technology, in particular to a damper switch device. Background technique [0002] In coal mining, the safety of coal mines is very important. Among them, the mine ventilation system is the key to ensure the safety of the mine, and the damper in the mine ventilation system is the key to maintaining the stable operation of the mine ventilation system. The damper is mainly set up for the passage of personnel and materials underground. While ensuring the passage of personnel and materials underground, it is also used to adjust the underground air flow to avoid short-circuit of air flow and ensure the reliable operation of the entire ventilation system. Whether the damper can be opened and closed quickly and conveniently will directly affect the production safety of the mine. [0003] At present, the opening and closing methods of the damper are mainly opened or closed by manual pulling, pushing, etc., because the...
