The invention provides an emergency protection system and method for an elevator, and the system comprises two damping assemblies which are arranged on the two opposite side faces of an elevator car, and each damping assembly comprises at least one damping wheel assembly; the two sets of triggering assemblies are arranged in one-to-one correspondence with the two sets of damping assemblies, each triggering assembly comprises a speed sensor and a power telescopic rod, one end of each power telescopic rod is connected with the outer side wall of the elevator car, and the other end of each power telescopic rod is connected with the corresponding damping assembly. The damping assembly can work when the elevator car falls rapidly, the buffer wheel can make contact with the side wall of the elevator shaft to provide damping force for the elevator car, and therefore the falling speed of the elevator is reduced.

    本发明提供一种电梯的紧急保护系统和方法,该系统包括:阻尼组件,包括设置于轿厢相背两侧面的两组,阻尼组件包括至少一个阻尼轮组件;触发组件,包括与两组阻尼组件一一对应设置的两组,触发组件包括速度传感器及动力伸缩杆,动力伸缩杆一端与电梯轿厢的外侧壁连接,另一端与阻尼组件连接,使用该系统按照本申请的方法工作,能够在电梯轿厢发生急速下坠时使阻尼组件工作,缓冲轮能够与电梯井的侧壁接触对电梯轿厢提供阻尼力,从而减缓电梯下坠速度。
