The invention relates to the technical field of lift truck safety and discloses an anti-stall falling device for an electric power rush-repair lift truck. The anti-stall falling device comprises an anti-stall falling device main body; a placement groove is formed in the inner wall of a fixed disc; speed reduction blocks are movably mounted in the placement groove; springs are fixedly connected tothe inner wall of the placement groove; a rotating disc is movably mounted in the fixed disc; telescopic rods are fixedly mounted on the outer wall of the rotating disc; and stop levers are fixedly mounted on the outer wall of the rotating disc. The telescopic rods are jacked up through oil in the rotating disc, when driving blocks on a connecting rope drive the rotating disc to rotate, the extending telescopic rods can abut against the speed reduction blocks in the replacement groove to rotate, and therefore the stop levers on the rotating disc can slide over the outer wall of the speed reduction blocks in an attached mode; the ascending and descending speed of the connecting ropes is reduced by means of friction force of the stop levers and the speed reduction blocks, and the effect of decelerating and buffering in the ascending and descending process of the lift truck is achieved.
本发明涉及升降车安全技术领域,且公开了一种用于电力抢修升降车的防失速坠落装置,包括防失速坠落装置主体,所述固定圆盘的内壁开设有安置槽,所述安置槽的内部活动安装有减速块,所述安置槽的内壁固定连接有弹簧,所述固定圆盘的内部活动安装有旋转圆盘,所述旋转圆盘的外壁固定安装有伸缩杆,所述旋转圆盘的外壁固定安装有挡杆。通过旋转圆盘内部的油液将伸缩杆顶起,在连接绳上的带动块带动旋转圆盘转动时,伸出的伸缩杆将会顶住安置槽内部的减速块转动,从而旋转圆盘上的挡杆将会贴着减速块的外壁滑过,借助两者的摩擦力将连接绳上升和回落的速度减缓,达到了升降车上升和回落过程中减速缓冲的效果。
