The invention belongs to the technical field of elevators, and discloses an elevator falling protection device which comprises an elevator car, a guide shoe and an opening and closing door, a speed detector is fixedly connected to the side face of the elevator car, an adjusting assembly is fixedly installed on the side face of the elevator car, and the lower end of the adjusting assembly fixedly communicates with a middle pipe. The bottom frame is additionally arranged at the bottom of the lift car, the push plate is arranged in the bottom frame in a sleeving mode, and hydraulic oil filled in the bottom frame is matched, so that when the lift car falls to the ground, second springs are compressed for buffering, and meanwhile the hydraulic oil is extruded into the side frames, and therefore auxiliary brake plates on the two sides rapidly move and clamp the rails on the two sides; the side friction force is further supplemented, downward impact potential energy is further reduced while elastic buffering is conducted, when falling cannot be stopped in the sliding friction distance of the brake plate, follow-up supplementary buffering and stopping are conducted, the actual falling protection effect is greatly improved, and the influence of falling on internal passengers is reduced.

    本发明属于电梯技术领域,且公开了一种电梯坠落保护装置,包括轿厢、导向靴和开关门,所述轿厢的侧面固定连接有速度检测器,所述轿厢的侧面固定安装有调节组件,所述调节组件的下端固定连通有中间管。本发明通过在轿厢的底部增设底部框,并在底部框中套设推板,配合底部框中填充的液压油,在当轿厢落地时,随着压缩二号弹簧进行缓冲的同时,将液压油挤压至侧边框中,从而使得两侧的辅助刹板快速移动并向着两侧轨道进行夹紧,进一步补充侧面摩擦力,在弹性缓冲的同时进一步降低向下的撞击势能,在刹停板滑动摩擦距离无法停止坠落时,进行后续的补充缓冲和止停,大大提高了实际坠落保护效果,减小坠落下对内部乘客的影响。
