The invention discloses a secondary protection mechanism for emergency unlocking of elevator landing doors, and relates to the technical field of emergency unlocking of doors. The two ends of the landing door are slidably installed on the lower sliding rail and the upper sliding rail correspondingly. The lower sliding rail and the upper sliding rail are fixedly mounted on a wall body; the unlocking assembly comprises a driving door knife and a driven door knife which are fixedly installed on the landing door. The driving door knife is fixedly mounted with the connecting belt and the steel wire rope; the connecting belt is mounted on two driving rollers arranged on a wall body in a matched manner; a clamping assembly installed on a lift car is connected with an adjusting wheel and a deflection wheel on a second buckle in a clamped mode, the second buckle is driven by the adjusting wheel to move upwards, at the moment, a first buckle and the second buckle are separated, a connecting belt is driven by a driving roller to move, and a driving door vane drives a landing door to move; the driving door vane and the driven door vane are installed on the first steel wire rope in a matched mode at the same time, so that the driving door vane and the driven door vane move in the opposite directions, and normal opening of the landing door is achieved.

    本发明公开了一种电梯层门紧急开锁的二次保护机构,涉及门紧急开锁技术领域,包括两个呈对开式的层门;层门的两端分别与下滑轨和上滑轨滑动安装;所述的下滑轨和上滑轨与墙体固定安装;开锁组件包括与层门固定安装的主动门刀和从动门刀;主动门刀与连接带和钢丝绳固定安装;连接带配合安装在墙体上设置的两个主动滚轮上;通过轿厢上安装的卡接组件与第二卡扣上的调节轮和偏转轮卡接,通过调节轮带动第二卡扣向上移动,此时第一卡扣和第二卡扣分离,通过主动滚轮带动连接带移动,实现主动门刀带动层门移动,主动门刀和从动门刀还同时配合安装在第一钢丝绳上,这样实现主动门刀和从动门刀向相反的方向移动,实现层门的正常开启。
