A self-locking type bottom cage door comprises a double-door type bottom cage door, the bottom cage door is provided with a turnover door lock plate, a door lock and a displacement sensor used in cooperation with the door lock plate, one end of the door lock abuts against the door lock plate through a door lock handle, the other end of the door lock is used in cooperation with collision iron on a suspension cage, the displacement sensor is connected with a controller, and the output end of the controller is connected with a motor. The self-locking type bottom cage door is of a double-hinge opening and closing type, and space limitation is reduced; through linkage of the door lock plate and the door lock, the three functions that the bottom cage door is automatically locked when the cage ascends, the bottom cage door lock is automatically opened when the cage descends, and the door lock is automatically reset when the bottom cage door is closed are achieved. When the bottom cage door is opened, the door lock plate rotates, the displacement sensor is triggered, the overall stopping effect of the elevator is achieved when the bottom cage door is opened, and safety is improved.
一种自锁式底笼门,包括双开门式底笼门,底笼门设有可翻转的门锁板、门锁和与门锁板配合使用的位移传感器,门锁的一端通过门锁柄顶在门锁板上,另一端与吊笼上的撞铁配合使用,位移传感器连接有控制器,控制器的输出端连接有电机。本发明的自锁式底笼门为双页开合式,减少空间限制;通过门锁板与门锁联动,实现吊笼升高时底笼门自动上锁、吊笼降低时底笼门锁自动打开、底笼门关闭时门锁自动复位这三大功能;底笼门打开使得门锁板转动,触动位移传感器,实现底笼门打开时升降机整体停机效果,增加安全性。
