The invention provides a labor-saving anti-falling device. The labor-saving anti-falling device includes an anti-falling device; the anti-falling device includes a rotating part and a fixed part; therotating part is rotatably arranged on the fixed part through a first rotating shaft; at least one hook is rotatably arranged on the rotating part; a limit rod is arranged on the fixed part; and the rotation of the rotating part generates a centrifugal force, so that the hook hooks the limit rod, thereby realizing the limit of the rotating part. The labor-saving anti-falling device also includes aladder-climbing labor-saving device; the first rotating shaft is fixedly connected to the rotating part; the end of the first rotating shaft is connected to the ladder-climbing labor-saving device; and the limit of the ladder-climbing labor-saving device is realized by the hook hooking the limit rod. The centrifugal force generated by the rotation of the rotating part is used for throwing the hook out, so that the hook can hook the limit rod, which ingeniously utilizes the centrifugal force to realize the limit, meets the requirements of anti-falling, and prevents the rotating part from rotating too fast, that is, prevents the operating personnel from moving too fast in the air, and plays a role of speed limiting.
本发明提供了一种省力防坠装置,包括防坠装置,所述防坠装置包括转动件和固定件,所述转动件通过第一转轴可转动式设置于固定件上,所述转动件上可转动设有至少一件挂钩,所述固定件上设有限位杆,转动件转动产生离心力实现挂钩勾住限位杆,从而实现转动件限位。所述省力防坠装置还包括爬梯省力装置,所述第一转轴与转动件之间固定连接,所述第一转轴的端部与爬梯省力装置连接,通过挂钩勾住限位杆实现对爬梯省力装置进行限位。利用转动件转动产生离心力将挂钩甩出实现挂钩勾住限位杆,巧妙的利用离心力实现限位,满足防坠需求,同时防止转动件转动速度过快,即防止作业人员在空中的运动速度过快,起到限速作用。
