Hand-operated type high-rise lifesaving device capable of lifting in self-controlled mode

Abstract

The invention provides a hand-operated type high-rise lifesaving device capable of lifting in a self-controlled mode, and the hand-operated type high-rise lifesaving device can manually lift in the self-controlled mode. Staff on a high building can be safely rescued without depending on a power supply when a disaster happens. A lifting device comprises an assembly housing, a lifesaving hanging basket, a lifesaving rope and the like, wherein a transmission mechanism fixing frame is fixedly arranged inside a lifting device assembly housing; a transmission gear group and a lifesaving rope friction wheel group are arranged on the fixing frame; and gears in the transmission gear group are coaxially connected with friction wheels in the lifesaving rope friction wheel group correspondingly. One of the lifesaving rope friction wheels is coaxially connected with one of the transmission gears and a transmission worm; the transmission worm is engaged with worm wire teeth through wheel teeth; and the worm is connected with a hand-operated handle by passing through the assembly housing. The lifesaving rope passes through gaps among the friction wheel group and penetrates through the middle part of the lifting device assembly housing. The two ends of the lifesaving rope are connected with safety hooks which can be hooked on the high building. The lifesaving hanging basket is connected with a fixed ring on the lifting device assembly housing through the rope. In use, one end of each safety hook is fixedly arranged on the high building, a passenger stands in the lifesaving hanging basket, and the handle is operated by hands to be controlled to lift, so that safe lifesaving is realized. The hand-operated type high-rise lifesaving device capable of lifting in the self-controlled mode is simple in structure, is convenient to operate, and is safe and reliable.

Description

technical field [0001] The invention relates to a high-rise life-saving device, in particular to a hand-operated self-controlled lifting high-rise life-saving device. Background technique [0002] High-rise residences are becoming more and more common in modern society. When disasters such as fires occur, the use of elevators or stairs will be restricted. If they cannot leave in time, it will cause safety hazards, and the use of electric lifting mechanisms will be limited by the power supply. , the present invention's hand-operated self-controlled lifting high-rise life-saving device is exactly in order to solve the high-rise life-saving problem. Contents of the invention [0003] The object of the present invention is to provide a hand-operated self-control lifting high-rise life-saving device with simple structure, stable operation, safety and reliability, and long service life. [0004] In order to solve the above-mentioned technical problems, the hand-operated self-co...
