Description

technical field

[0001] The invention relates to mechanical technology, in particular to a damper locking device and a damper locking system. Background technique

[0002] The damper is the main ventilation building in the coal mine that can not only block the wind flow but also pass vehicles and pedestrians. Its function is to ensure that the underground wind flow flows according to the prescribed route and direction, and to control the wind flow. In order to avoid short-circuiting the airflow and destroying the entire ventilation system when the damper is opened, at least two airways must be installed in the same lane when the damper is set, and the damper should be locked. At the same time, the safety of pedestrians and vehicles when passing through the damper is also ensured. .

[0003] The existing damper locking device realizes the locking function through the limit position of the steel wire rope installed on the door leaf. Since the rope is a flexible connection, whe...
