High-rise building life line

Abstract

The invention relates to a high-rise building life line which comprises a suspension arm composed of an outer sleeve and an inner sleeve. An initial speed limiter and at least one secondary speed limiter are arranged in the inner sleeve. A tail trolley is arranged behind the last secondary speed limiter. The initial speed limiter, the secondary speed limiters and the tail trolley are sequentially connected in series through the same steel wire rope. The high-rise building life line is reasonable in structure, and is the only escape device in which the multiple speed limiters are adopted for being connected with the same steel wire rope in series in China at present, and continuous escaping can be achieved through the high-rise building life line; the occupied space is small, the naked steel wire rope of 3 mm is used, and when the life line is stored for standby, under the circumstance of the same high limit, the size occupied by the line is only one twenty seventh that of a current descent control device sold in the market; the life line is easy to use, easy to control, low in requirement for users, good in safety, free from maintenance and long in service life, an escaper can autonomously control the life line and brake the life line in the midway to rescue people in distress in the floor below, and the evacuation speed of the life line is the highest among the current similar products.

Description

technical field [0001] The invention relates to a fire-fighting escape device, in particular to a high-rise building lifeline. Background technique [0002] With the development of the times, there are more and more high-rise buildings (abbreviated as high-rise buildings), and the safe escape of high-rise buildings has become an urgent problem to be solved. [0003] People who live and work in high-rise buildings will cause casualties if they cannot escape in time when encountering events such as fire, explosion, earthquake, and hijacking. The U.S. 911 incident and the casualty figures of domestic previous major high-rise building fires show that in fact there is still no simple and convenient high-rise building safety escape device (rescue or self-rescue) generally accepted at present. [0004] In order to solve the safe escape problem of high-rise buildings, various methods have been adopted in practice at home and abroad, such as aerial ladders, helicopters, air cushions...

AI Technical Summary

Problems solved by technology

However, this requires the users of the lifeline to have good psychological and physical qualities, and well-trained skills to ensure safety and reliability. In the tense and chaotic atmosphere of disasters or accidents, untrained ordinary It is not only dangerous but also often impossible for people, old people, children, injured or fainted people to rely on existing high-rise building lifelines to save themselves or each other, especially in the case of higher floors, even if lifelines are equipped Difficult to use correctly and safely
