The invention provides a lift car mechanical locking device which comprises a locking action structure and a locking positioning structure, the locking device is arranged between a lift car and a guide rail and forms mechanical rigid connection between the lift car and the guide rail, and the locking device is further provided with a safety circuit switch. A trigger part of the safety loop switch is connected with the locking action structure, the locking action structure is provided with a locking position and a recovery position, functions of the locking action structure are switched between the locking position and the recovery position, and the safety loop switch is triggered at the locking position. According to the locking device, a mechanical locking structure is combined with a safety loop in a linkage mode, mechanical locking and the safety loop act at the same time, resetting also acts at the same time, use is convenient, conversion can be conveniently conducted, the safety and convenience in the overhaul process are effectively improved, and the maintenance cost is reduced. Mechanical locking and closing of a safety circuit can be completed at the same time only through one action.
本发明提出了一种轿厢机械锁止装置,锁止装置包括有锁止动作结构以及锁止定位结构,锁止装置设置在轿厢与导轨之间,并对轿厢和导轨形成机械刚性连接,锁止装置上还设置有安全回路开关,安全回路开关的触发部分与锁止动作结构连接,锁止动作结构具有锁止位和恢复位,并在锁止位和恢复位之间功能转换,在锁止位上时,同时触发安全回路开关。锁止装置采用机械锁止结构以安全回路结合联动的方式,实现机械锁止与安全回路的同时作用,并且复位也是同时起效,使用方便,可以便捷进行转换,有效提高的检修时的安全性和便捷性,只需要一个动作就可以同时完成机械锁止和安全回路的闭合。
