The invention relates to the technical field of elevator car self-locking devices, in particular to an elevator car self-locking device. The elevator car self-locking device comprises two symmetrically-arranged derricks, a car is connected between the two derricks in a sliding mode, and each derrick is provided with two racks. The two electric self-locking modules are symmetrically arranged, driven by a double-end motor and used for achieving electric self-locking of the lift car, and the fixed-point self-locking mechanisms are installed on the two side faces of the lift car and used for achieving fixed-point self-locking of the lift car. The fixed-point self-locking mechanism comprises a stall shaft, a pressure adjusting piece, a driving shaft rotationally connected to the lift car, a transmission worm and a set of regularly-distributed brake shafts, and the stall shaft is in transmission connection with the driving shaft through a first chain belt. The elevator car self-locking device has the beneficial effects that the elevator car self-locking device can integrally achieve stall self-locking of the elevator car, safety limiting self-locking of the elevator in the static state and electric control self-locking of the elevator car, and then the safety of the elevator car during working can be effectively improved.

    本发明涉及电梯轿厢自锁装置技术领域,具体为一种电梯轿厢自锁装置。一种电梯轿厢自锁装置,包括两个对称设置的井架,两个井架之间滑动连接有轿厢,每个井架上均安装有两个齿条,还包括;两个对称设置且通过双头电机驱动的电驱自锁模组,用于实现轿厢的电驱自锁,安装于轿厢两侧面的定点自锁机构,用于实现轿厢的定点自锁,定点自锁机构包括失速轴、调压件、转动连接于轿厢上的主动轴、传动蜗杆和一组规则分布的制动轴,失速轴通过第一链带与主动轴传动连接。本发明的有益效果是:本电梯轿厢自锁装置能够一体的实现电梯轿厢的失速自锁、电梯静止状态下的安全限位自锁及电梯轿厢的电控自锁,继而能够多效提高电梯轿厢工作时的安全性。
