Abstract

The invention relates to a double-guided counterweight rod type damper locking device, which includes a housing, a universal wire rope pulley, a guiding counterweight rod, a guiding bearing wheel, a triangular lock block, an unlocking cylinder and a fixed bracket for the cylinder. During normal operation, the locking device In the locked state, the piston rod of the unlocking cylinder is extended, and the triangular lock block at the end of the piston rod of the unlocking cylinder is located above the two guide weight rods. The block pushes to the top of the other guide weight rod and locks it; during the unlocking period, the piston rod of the unlocking cylinder shrinks, and the piston rod drives the triangular lock block to break away from the top of the guide weight rod, and the two guide weight rods can move at the same time , that is, the dampers on both sides can be opened at the same time, and the device can be locked reliably during normal periods. In the event of a fire or other accident in the mine, it can release the damper lock, urgently regulate the underground air flow, and improve the ventilation control ability of the mine catastrophe.

Description

technical field [0001] The invention relates to a damper locking device, in particular to a double-guiding counterweight rod type damper locking device. Background technique [0002] The damper is a very important ventilation facility in the mine ventilation system and plays an irreplaceable role in the ventilation system. In order to maintain the stability and reliability of the ventilation system, the two dampers in the same group must use a locking device to lock the two dampers so that they cannot be opened at the same time. When a fire accident occurs in a mine, the catastrophic ventilation system needs to be adjusted in an emergency to divert the smoke flow and prevent the poisonous and harmful gases from spreading to the main personnel's workplace. The invention provides a dual-guiding counterweight rod type damper locking device, which is reliable in normal period, and can release the damper locking in the event of a fire or other accidents in a mine, urgently regul...
