Abstract

The invention relates to an air door locking device capable of remotely unlocking in an underground coal mine. The air door locking device comprises a shell, a rope combing hole, a short shaft windingdrum, a steel wire rope, a sliding locking block, a locking steel ball, a sliding groove, a double-acting air cylinder and a state sensor; during normal work, a piston rod of the double-acting air cylinder is in an extension state, and when the locking state is released, the piston rod of the double-acting air cylinder is in a contraction state; a groove is formed in the short shaft winding drum,the piston rod of the double-acting air cylinder acts with the locking steel ball and the groove to achieve opening and closing of the air door locking function, an electromagnetic valve is installedon the double-acting air cylinder, the electromagnetic valve is connected into a remote control looped network, a ground upper computer software remotely controls the electromagnetic valve, and extension and contraction of the piston rod of the double-acting air cylinder are adjusted. According to the air door locking device capable of remotely unlocking in the underground coal mine, the lockingof the air doors can be released remotely, when accidents such as fire and gas occur underground, the two air doors can be opened emergently, the underground air flow can be adjusted, the influence range of the underground gas and fire accidents can be effectively controlled, and the casualties and property loss of the mine are 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,...
