The invention discloses a protection device for preventing sliding of an elevator during door opening. The protection device comprises an elevator shaft, and each layer of the inner wall of the elevator shaft is provided with a fixed magnetic block; the elevator car and sensing mechanism comprises an elevator car arranged in the elevator shaft, a base is arranged at the bottom of the elevator car, a movable magnetic block which can stretch out and draw back inwards and is matched with the fixed magnetic block is arranged on one side wall of the base, and a movable armature is arranged at the top of one end of the movable magnetic block; the braking mechanism comprises braking plates which are arranged on the two sides of the lower end of the interior of the base and stretch out and draw back on the two side walls of the base, each layer of the inner wall of the elevator shaft is provided with a metal clamping plate matched with the corresponding braking plate, and when a car slides, telescopic rods can drive the braking plates to stretch out rapidly under pushing of bidirectional hydraulic rods; due to the fact that the tail end of the brake plate is reversely pushed by the brake plate, the lift car cannot continuously slide downwards, and the lift car brake device is simple in structure, efficient and practical.

    本发明公开了一种防止电梯开门溜车保护装置,包括梯井,所述梯井的内壁每一层均设置有固定磁块;轿厢及感应机构,包括设置于所述梯井内部的轿厢,所述轿厢的底部设置有底座,所述底座的一侧壁设置有可内外伸缩并与所述固定磁块相配合的的活动磁块,所述活动磁块的一端顶部设置有动衔铁;制动机构,包括设置于所述底座内部下端两侧,并伸缩于底座两侧壁的制动板,所述梯井的内壁每一层均设置有与所述制动板相配合的金属卡板,当轿厢出现溜车时,伸缩杆在双向液压杆的顶推下会带动制动板迅速伸出,直至制动板的末端与金属卡板上的卡槽相嵌合为止,由于受到制动板的反向抵推,因此轿厢无法继续下溜,结构简单,高效实用。
