The invention provides elevator overspeed protection equipment which comprises an elevator car, a protection assembly is installed on the outer side wall of the elevator car, and the protection assembly comprises a braking guide rail, a fixed seat, an installation seat, a double-end lead screw, two braking vanes, a braking motor and a sliding seat. The fixing base is fixedly connected to the rear surface of the lift car. When an elevator is overspeed, a brake motor drives a double-end lead screw to rotate, the double-end lead screw drives two brake plates through threads, the two brake plates get close to each other, the brake plates make contact with a brake guide rail through brake pads, then brake sudden stop of the lift car can be achieved, at the moment, the lift car generates huge inertia, the lift car drives a fixing base, and the lift car is driven to move upwards. The sliding seat slides in the fixed seat, the buffering and damping effects on the lift car can be achieved, brake type emergency stop is adopted, a damping mechanism is matched, the situation that people taking an elevator fall down or violently collide with inner wall plates of the lift car during emergency stop can be avoided, and the stability of the lift car during emergency stop is improved.
本发明提供了一种电梯超速保护设备,包括轿厢,所述轿厢的外侧壁安装有保护组件,所述保护组件包括刹停导轨、固定座、安装座、双头丝杆、两个刹车板、刹车电机和滑动座;所述固定座固定连接于所述轿厢的后表面。本发明当电梯超速时,刹车电机带动双头丝杆转动,双头丝杆通过螺纹带动两个刹车板,两个刹车板相互靠近,刹车板通过刹车片与刹停导轨接触,进而可以实现对轿厢的刹车急停,此时轿厢产生巨大的惯性,轿厢带动固定座,滑动座在固定座内滑动,可以对轿厢起到缓冲减震的作用,本发明采用刹车式急停并配合减震机构,可以避免乘坐电梯的人在急停时出现摔倒,或者与轿厢内部壁板发生激烈碰撞的情况,增加了轿厢急停时的稳定性。
