An elevator anti-falling safety protection device capable of operating safety tongs instantly is composed of an L-shaped sliding plate, an N-shaped lifting plate and a C-shaped sliding sleeve, a hanging steel wire rope connecting hole is formed in the upper portion of the N-shaped lifting plate and used for being connected with a hanging steel wire rope, the lower end of the N-shaped lifting plate is fixedly connected with the C-shaped sliding sleeve, and the L-shaped sliding plate is connected with the C-shaped sliding sleeve in a sliding mode. The lower end of the L-shaped sliding plate extends out of the C-shaped sliding sleeve and is connected with the lift car, the L-shaped sliding plate, the N-shaped lifting plate and the C-shaped sliding sleeve are connected and connected with the upper suspension steel wire rope, the lower suspension steel wire rope and the lift car, the safety tongs can be triggered to act when the suspension steel wire ropes are broken, and the device is installed at the top of the lift car and is irrelevant to whether an installed elevator has a machine room or not. Even if the elevator is an elevator without a machine room, a top layer platform for installing the speed limiter does not need to be built at the top of the hoistway.
一种即时操纵安全钳的电梯抗坠落安全保护装置,由L型滑板、N型提拉板和C型滑套构成,N型提拉板上方设有悬挂钢丝绳连接孔用于与悬挂钢丝绳连接,N型提拉板下端与C型滑套固定连接,L型滑板与C型滑套滑动连接,L型滑板下端伸出C型滑套并与轿厢连接,通过L型滑板、N型提拉板及C型滑套的连接并与上下的悬挂钢丝绳及轿厢连接,使得其能够在悬挂钢丝绳断裂时触发安全钳动作,且本装置安装在轿厢顶部,故与安装的电梯是有、无机房无关,即便是无机房电梯,也不需要在井道顶部搭建安装限速器用的顶层平台。
