The invention belongs to the technical field of elevator lifting systems, particularly relates to an elevator lifting safe operation system. Aiming at the problems that in the prior art, no vertical anti-pinch protection device exists, so that once the situation happens, great casualty accidents are inevitably caused, and great potential safety hazards are brought to people taking an elevator, thefollowing scheme is proposed, the elevator lifting safe operation system comprises a lift car connected in a hoistway in a lifting mode, a landing door is arranged on one side of the hoistway, a cardoor corresponding to the landing door is arranged on one side of the lift car, and two first sliding grooves are symmetrically formed in the inner walls of the sides, away from each other, of the hoistway. According to the elevator lifting safe operation system, the landing door is opened, so that a stop block can be located between two limiting blocks, the effect of vertical limiting operation protection is achieved, a limiting disc is unlimited by pulling out an inserting rod, the limiting blocks can move to the position above the stop block, so that the effect of stopping the elevator fromfalling is achieved, the effect of protecting passengers is achieved, and the safety of going in and out of the elevator and taking the elevator is greatly improved.

    本发明属于电梯升降系统技术领域,尤其是一种电梯升降安全运行系统,针对现有技术中存在没有竖向防夹保护装置,导致一旦此类情况发生,必然造成极大的伤亡事故,给乘坐电梯的人们带来很大安全隐患的问题,现提出如下方案,其包括升降连接在井道中的轿厢,所述井道的一侧设有层门,轿厢的一侧设有与层门相对应的厢门,所述井道相互远离的一侧内壁对称设有两个第一滑槽,本发明中,通过层门开启可以使挡块位于两个限位块之间,以此起到竖向限位运行保护的效果,通过拔出插杆解除对限位盘的限位,可以使限位块移动至挡块之上,以此实现阻挡电梯下落的作用,对乘客起到保护的效果,大大提高了进出和乘坐电梯的安全性。
