The invention discloses an elevator anti-falling device, and relates to the technical field of elevator safety equipment, the elevator anti-falling device comprises an execution assembly, the execution assembly comprises a mounting plate, two reinforcing frames which are symmetrically arranged are fixedly mounted at the two ends of the mounting plate, and a swing clamping plate is arranged on the outer side of each reinforcing frame; and the swinging clamping plate is movably mounted on the mounting plate through a clamping plate bracket. Triggering is achieved through air resistance generated when an elevator falls, and an elevator car is locked through the meshing relation between the two swing clamping plates and the metal teeth; each movable part adopts an active moving mode, so that as long as the elevator runs, all the movable parts can move in a small range, and it is guaranteed that joints cannot be damaged due to long-time non-working; a closed-loop detection triggering mode is adopted, stable and reliable operation of the triggering assembly is guaranteed, and the arranged reinforcing frame can guarantee that the swing clamping plate stably supports the elevator car.

    本发明公开了一种电梯防坠落装置,涉及电梯安全设备技术领域,包括执行组件,所述执行组件包括安装板,安装板的两端固定安装有两个对称设置的加强架,每个加强架的外侧均设置有摆动卡接板,摆动卡接板通过卡接板支架活动安装在安装板上。本发明通过电梯坠落时的空气阻力来实现触发,利用两个摆动卡接板与金属齿的啮合关系,将电梯轿厢锁止;各个活动部件均采用主动活动的方式,只要电梯在运转,各个活动部件之间均会小幅度的运动,保证连接处不会因长时间不工作坏死;采用闭环的检测触发方式,保证了触发组件稳定可靠的运行,并且设置的加强架,可以保证摆动卡接板稳定的将电梯轿厢支撑住。
