Double-guide balance weight lever type air door locking device
The invention relates to a double-guide balance weight lever type air door locking device. The double-guide balance weight lever type air door locking device comprises a shell, a universal steel wirerope pulley, guide balance weight levers, a guide bearing wheel, a triangular locking block, an unlocking air cylinder and an air cylinder fixing support, in a normal working period, the locking device is in a locking state, a piston rod of the unlocking cylinder extends, the triangular locking block at the end of the piston rod of the unlocking air cylinder is located above the two guide balanceweight levers, after the air door on one side is opened, the corresponding guide balance weight lever is lifted through a steel wire rope, and the triangular locking block is pushed to the position above the other guide balance weight lever and locks the other guide balance weight lever; and in the unlocking period, the piston rod of the unlocking air cylinder contracts, the piston rod drives thetriangular locking block to be disengaged from the upper portions of the guiding balance weight levers, the two guiding balance weight levers can move at the same time, in other words, the air doors on the two corresponding sides can be opened at the same time, locking of the air doors in the normal period is reliable, air door locking can be relieved and underground air flow can be emergently regulated, and the mine catastrophe ventilation regulation and control capability is improved.
本发明涉及一种双导向配重杆式风门闭锁装置，包括壳体、万向钢丝绳滑轮、导向配重杆、导向轴承轮、三角锁块、解锁气缸和气缸固定支架，正常工作时期，闭锁装置为闭锁状态，解锁气缸活塞杆伸长，解锁气缸活塞杆端头的三角锁块位于两根导向配重杆上方，一侧风门打开后，通过钢丝绳将对应的导向配重杆提起，将三角锁块推向另一个导向配重杆的上方并将其闭锁；解除闭锁时期，解锁气缸活塞杆收缩，活塞杆带动三角锁块脱离了导向配重杆的上方，两根导向配重杆可同时运动，即对应两侧风门可同时开启，本装置正常时期闭锁可靠，在矿井发生火灾等事故时，能够解除风门闭锁，紧急调控井下风流，提高矿井灾变通风调控能力。
