The invention discloses a device for preventing elevator top rushing in the technical field of elevators, and the device comprises a liquid box, a liquid outlet hole is formed in the top of the liquid box, a liquid discharge pipe is communicated to the liquid outlet hole, a liquid accumulation box is fixedly connected to the top of the liquid discharge pipe, a plurality of piston cylinders are arranged at the bottom of the liquid box, and a piston rod is slidably connected to the interior of each piston cylinder; the bottom end of the piston rod is fixedly connected with the same movable plate, and the movable plate is fixedly connected with a plurality of springs. According to the scheme, a first section of buffering is formed for the elevator through the springs, the jacking speed of the elevator is slowed down firstly, then a second section of buffering is formed for the elevator through cooperation of the piston rod and the liquid box, the jacking speed of the elevator is further slowed down, and injuries possibly caused to passengers during jacking of the elevator are effectively reduced.
本申请公开了电梯技术领域的一种防止电梯冲顶的装置,包括液箱,液箱顶部设有出液孔,出液孔上连通有排液管,排液管的顶部固定连接有积液箱,所述液箱的底部设有多个活塞缸,每个活塞缸中均滑动连接有活塞杆,所述活塞杆的底端固定连接有同一块活动板,所述活动板上固定连接有多根弹簧。本方案通过多个弹簧对电梯形成一段缓冲,先减缓电梯的冲顶速度,然后再通过活塞杆与液箱的配合对电梯形成二段缓冲,进一步的减缓了电梯的冲顶速度,有效的降低了电梯冲顶时可能会为乘客造成的伤害。
