The elevator lifting main cable safety device comprises a mounting plate, a guide wheel and a main cable, the main cable moves in a guide groove in the side face of the guide wheel, a through groove is formed in the position, corresponding to the guide wheel, of the mounting plate, and the two ends of the main cable both penetrate through the through groove and then extend to the position below the mounting plate. Mounting bases are arranged on the mounting plate and located on the two sides of the guide wheels. By arranging the cable lock kit and the hook centrifugal assembly, after the main cable stalls, the guide wheel can be rapidly driven to rotate, at the moment, the guide wheel rotates rapidly, then the hook centrifugal assembly extends out of the guide wheel under the action of centrifugal force and is hung on the cable lock kit, and the cable lock kit can be pulled through the hook centrifugal assembly when the guide wheel rotates; at the moment, the mooring rope lock sleeve piece is pulled to lock the main mooring rope, so that the guide wheel can be controlled to rotate through the mooring rope lock sleeve piece while the main mooring rope is locked through the mooring rope lock sleeve piece, the effect of interlocking the guide wheel and the main mooring rope is achieved, and a layer of insurance is added to the main mooring rope.
本发明公开了一种电梯升降主缆保险装置,包括安装板、导轮和主缆绳,所述主缆绳活动在导轮侧面的导槽内,安装板上对应导轮位置设置有通槽,主缆绳的两顿均穿过通槽后延伸至安装板的下方,安装板上位于导轮两侧的位置设置有安装座。本发明是通过设置缆绳锁套件和挂钩离心组件,在主缆绳失速后会飞速带动导轮转动,此时的导轮快速转动,然后挂钩离心组件在离心力的作用下伸出导轮并挂在缆绳锁套件上,导轮转动会通过挂钩离心组件拉动缆绳锁套件,此时的缆绳锁套件被拉动会锁住主缆绳,这样便可一边通过缆绳锁套件控制导轮转动,一边通过缆绳锁套件锁住主缆绳,达到了对导轮和主缆绳进行互锁的效果,在主缆绳上加了一层保险。
