The invention relates to the technical field of lifting equipment, and provides an anti-falling mechanism, a driving device and lifting equipment. The anti-falling mechanism comprises a fixed main body, a trigger assembly and an anti-falling assembly; the fixed main body is mounted on the guide wheel group; the trigger assembly comprises a trigger shaft, a speed measurement pressing wheel and a trigger part, the trigger shaft is rotatably arranged on the fixed main body, and the speed measurement pressing wheel and the trigger part are both arranged on the trigger shaft; the anti-falling assembly comprises a locking piece and an elastic piece, the locking piece is rotatably arranged on the fixed main body, the rotating center of the locking piece is eccentrically arranged, and the elastic piece is connected with the fixed main body and the trigger component; when the driving device stalls and falls, the speed measuring pressing wheel drives the triggering part to accelerate through the triggering shaft, and when the rotating speed of the triggering part reaches the preset triggering rotating speed, the triggering part drives the locking part to overcome the elastic force of the elastic part to rotate, and the locking part abuts against the guiding part to achieve locking. The lifting device is compact in structural arrangement, low in manufacturing cost, small in needed installation space and capable of being widely applied to lifting devices with guide rails.
本发明涉及升降设备技术领域,提供一种防坠机构、驱动装置及升降设备。防坠机构包括固定主体、触发组件和防坠组件;固定主体安装至导向轮组;触发组件包括触发轴、测速压轮和触发部件,触发轴可转动地设于固定主体,测速压轮和触发部件均设于触发轴;防坠组件包括锁止件和弹性件,锁止件可转动地设于固定主体,锁止件的转动中心偏心设置,弹性件与固定主体和触发部件连接;当驱动装置失速下坠,测速压轮通过触发轴带动触发部件加速,使触发部件的转速达到预设触发转速时,触发部件带动锁止件克服弹性件的弹力进行转动,使锁止件抵接至导向部件实现锁止。本发明的结构设置紧凑,制造成本较低,所需安装空间较小,可广泛应用于带有导轨的升降设备。
