Embodiment Construction
[0012] Below in conjunction with accompanying drawing, the present invention will be further described:
[0013] like figure 1 , figure 2 , image 3 , Figure 4 As shown, the hand-operated self-controlled lifting high-rise lifesaving device of the present invention includes a lifting device assembly shell 1, a lifesaving hanging basket 10, a lifesaving rope 5, and the like. The transmission mechanism fixing frame 2 is fixed inside the housing 1 of the lifting device assembly. A transmission gear set 6 and a lifeline friction wheel set 7 are arranged on the fixed frame 2 . The gears in the transmission gear set 6 are coaxially connected with the corresponding life-saving rope friction wheels in the life-saving rope friction wheel set 7 . One of the lifeline friction wheels is coaxially connected with one of the corresponding transmission gears and with the transmission worm gear 8 . The transmission worm gear 8 meshes with the worm 9 through gear teeth. The worm 9 passe...
