The invention relates to a traction type drive elevator installation protection device, in particular to an elevator anti-falling device. When a lift car is in a normal state, a limiting block is matched with a stopping hook, so that a hoisting rope drives the lift car to move up and down by matching with a stopping warping plate; and when the hoisting rope is broken, under the action of gravity of the upper end of the stopping warping plate and the action of a tension spring, the stopping hook rotates outwards so as to be hooked on a stopping bar on a stopping vertical ladder, and further falling is prevented.

    本发明涉及曳引式驱动型电梯安装保护装置,具体涉及一种电梯防坠装置。轿厢正常状态下,限位块和阻拦钩配合,使曳引绳通过配合阻拦翘板带动轿厢上下移动;当曳引绳断裂后,在阻拦翘板上端的重力下以及拉簧的作用下,阻拦钩往外旋转从而钩在阻拦竖梯上的阻拦杠上,防止进一步下坠。
