The invention relates to an adjustable-speed descent control device for high-rise lifesaving, and relates to a high-rise lifesaving device suitable to be used by people in a purely-mechanical mode. The adjustable-speed descent control device has a structure that: 2 to 4 pulleys are arranged at bulged parts of continuous S-shaped edges of two fixed plates I connected through bolts; fixed plates IIis assembled in the same way; top ends of the fixed plates I and the fixed plates II are connected by two connection plates; the S-shaped edges of the fixed plates I are in concave-convex correspondence with those of the fixed plates II, and a damping wheel set is arranged at the bottommost pair of S-shaped bulged parts; connection rings are machined on extension handles at the bottoms of the fixed plates I; a speed adjusting device is hinged at the upper parts of the connection rings; the speed adjusting device is sleeved on extension handles at the bottoms of the fixed plates II; and steel wire ropes are arranged between the pulleys on the fixed plates I and the fixed plates II and pass through the two connection plates. The high-rise lifesaving device has the advantages of novel structure, simple and convenient machining, low cost, convenient use, safety, reliability and the like, and thus the high-rise lifesaving device is a novel adjustable-speed descent control device for high-rise lifesaving which integrates economy and practicability into a whole.
Description
technical field [0001] The speed-adjustable high-rise life-saving descending device of the present invention relates to a high-rise life-saving device for human use in a purely mechanical manner. Background technique [0002] At present, among urban disaster accidents, fire is a sudden disaster with high frequency, wide coverage, great destructiveness and strong repercussions. A high-rise building suddenly catches fire, the elevator can’t be used, the stairs are blocked, and you can’t fly up or jump down. How can you escape quickly? There are many, many such situations every year, and many people are killed because they cannot escape. While people are increasingly using various high-tech and modern methods for safety protection, they have neglected that if an accident occurs, it is not possible to use external forces (such as electricity, because the power supply is usually cut off in case of fire) ) and various modern means, relying on our most basic and simplest way, tha...
