The invention discloses a high-rise lifesaving descent control device, and belongs to machinery. The descent control device comprises a base, wherein the upper part of the base is provided with a pair of brake disc supports and a pair of speed-regulating cam supports; each support is provided with a self-aligning bearing assembly which is used for installing main shafts and auxiliary shafts; the pair of brake disc supports arranged on the base are provided with the main shafts, and each main shaft is sequentially provided with a chain wheel I, a brake disc and a main reel; the other speed-regulating cam supports arranged on the base are provided with the auxiliary shafts, and each auxiliary shaft is sequentially provided with a chain wheel II, a speed-regulating cam and an auxiliary reel; a brake device is arranged at the upper part of the base at the main shaft side; the chain wheel I arranged on each main shaft and the chain wheel II arranged on each auxiliary shaft are mutually connected through a chain so as to form a chain drive mechanism; and each main reel and each auxiliary reel are respectively wound with a steel wire rope so as to form a lifesaving descent control mechanism which is formed by winding of the main reels and the steel wire ropes as well as the auxiliary reels and the other steel wire ropes. The descent control device provided by the invention has the characteristics of simple structure, adjustable speed, capability of hovering in air and slowly descending with a plurality of people and good reusability.
Description
technical field [0001] The invention relates to machinery, in particular to a high-rise life-saving descender, in particular to a high-rise life-saving descender for high-rise buildings with simple structure, adjustable speed, hovering in the air, multi-person descending, and reciprocating use. Background technique [0002] With the rapid development of modern society, the urbanization process is further accelerated, and there are more and more high-rise buildings. However, in the event of a critical situation such as an earthquake or fire, it is difficult for people living in high-rise buildings to escape. Especially when stairs and elevators are blocked and cannot be used, in order to gain more escape time, people often choose to escape from windows, balconies or roofs to the ground, but because the floor is too high and there is no suitable escape device, it will cause more Large casualties and unnecessary property damage. Utility model content [0003] The purpose of ...
