Portable high-rise slow-fall escape device

Abstract

The portable high-rise slow-fall escape device of the present invention is composed of a pulley block composed of a flexible rope, a movable pulley and a fixed pulley, a friction plate and a bracket; the lower part of the bracket is provided with a man-carrying device that can slide along the flexible rope; A pulley set composed of fixed pulleys, and a friction plate that can contact each pulley is provided; the flexible rope alternately bypasses the fixed pulleys and movable pulleys of each set of pulleys from bottom to top. The escape device of the present invention has the effect of self-adaptation, and compared with the prior art, it overcomes the defect that it is difficult for a heavy person to escape. The portable slow-fall escape device for high-rise buildings of the present invention has simple structure, stable slow-fall, safe and reliable effect, and self-adaptive performance to weight.

Description

technical field [0001] The invention relates to first aid in a dangerous state, in particular to a portable slow-fall escape device for a high-rise building in a dangerous state. Background technique [0002] With the development of society, the number of urban population continues to increase, and high-rise buildings have played a role in alleviating the sharp increase in population. High-rise buildings have brought convenience to the lives of residents, but when disasters such as fires, earthquakes, gas leaks and other disasters take place, effective high-rise escape methods have become a major problem. At present, when accidents and dangers occur, most people choose to escape from high-rise buildings through elevators or stairs. However, the space of stairs and elevators in high-rise buildings is limited, and there are relatively many residents in high-rise buildings. Choosing elevators and stairs to escape will inevitably lead to congestion. situation, and even a stampe...

Problems solved by technology

At present, when accidents and dangers occur, most people choose to escape from high-rise buildings through elevators or stairs. However, the space of stairs and elevators in high-rise buildings is limited, and there are relatively many residents in high-rise buildings. Choosing elevators and stairs to escape will inevitably lead to congestion. situation, and even a stampede, leading to successive tragedies

[0003] Existing high-rise escape devices can be roughly divided into two types: damping type and deceleration disc type. These devices are composed of pull rods, rope guide pulleys, pull rod shafts, etc. These devices have complex structures, and some devices are equipped with motors, resulting in excessive weight, difficult operation and control, and expensive prices, which are not conducive to popularization
