Abstract

The invention relates to an air door locking device that can be remotely unlocked in a coal mine, comprising a casing, a comb rope hole, a short shaft drum, a steel wire rope, a sliding lock block, a locking steel ball, a chute, a double-acting cylinder and a state sensor; it works normally. When the piston rod of the double-acting cylinder is in an extended state, when the locked state is released, the piston rod of the double-acting cylinder is in a retracted state; a groove is provided on the short-axis drum, and the piston rod of the double-acting cylinder is connected with the locking steel ball. The opening and closing function of the air door can be realized by the action of the groove and the groove. A solenoid valve is installed on the double-acting cylinder, and the solenoid valve is connected to the remote control ring network. grow and shrink. The invention can remotely realize the release of the air door lock, and in the event of a fire, gas and other accidents in the underground, two air doors can be opened urgently, the air flow in the underground can be adjusted, the influence scope of the underground gas and fire accidents can be effectively controlled, and the casualties and property losses of the mine can be reduced.

Description

technical field [0001] The invention relates to the field of underground coal mine ventilation systems and mine disaster relief, in particular to an air door locking device capable of remotely unlocking underground coal mines. Background technique [0002] Coal mine underground ventilation system is the foundation of mine safety production. The damper is one of the main components of the ventilation system. The damper is a ventilation facility arranged between the inlet and outlet air lanes to block the wind flow. A locking device is installed between the two air doors in the underground coal mine. After one air door is opened, the other air door cannot be opened to prevent the two air doors from opening at the same time and causing a short circuit of the wind flow. However, when some accidents such as fire or gas outburst occur in coal mines, the disaster ventilation system needs to be adjusted. Small accidents affect the area, reducing mine economic losses and casualties,...
