The invention discloses a protection device for preventing accidental movement of an elevator. The protection device comprises an elevator shaft, guiding rails arranged on the two sides of an inner cavity of the elevator shaft and a car moving between the guiding rails on the two sides; a control cabinet is arranged in an upper machine room of the elevator shaft; a locking device is arranged on the car; multiple limiting plates corresponding to all floors are arranged on one guiding rail; when the car is located on the floor flat bed, the locking device on the car is aligned to the limiting plate on the guiding rail, the control cabinet controls an electric pushing rod to extend through a relay, the electric pushing rod pushes a supporting rod to get close to the limiting plate until the supporting rod is inserted in an opening in the limiting plate, and the car is locked and fixed at the moment. The protection device for preventing accidental movement of the elevator is realized through cooperative locking and fixing of the locking device mounted at the top of the outer side of the car and the limiting plates mounted on the guiding rail, the elevator car in the flat bed state canbe locked and fixed, and accidental movement of the elevator car can be prevented.
本发明公开了一种防止电梯意外移动的保护装置,包括:电梯井道、设置在电梯井道内腔两侧的导轨以及运行在两侧导轨之间的轿厢,电梯井道的上部机房内设置有控制柜,轿厢上设置有锁止装置,导轨上对应每个楼层设置有多个限位板;当轿厢在楼层平层时,轿厢上的锁止装置与导轨上的限位板对齐,控制柜通过继电器控制电动推杆进行伸长,电动推杆推动支撑杆向限位板靠近,直至支撑杆插入限位板上的开孔中,此时轿厢被锁止固定。本发明的防止电梯意外移动保护装置是由轿厢外侧顶部安装的锁止装置与导轨上安装的限位板相配合锁止固定实现的,可对平层状态的电梯轿厢进行锁止固定,防止电梯轿厢的意外移动。
