A fast escape self-rescue device without power

Abstract

The invention relates to a self-rescue device for quick escape without power, comprising a wire rope winch and a fixed protection box outside the wire rope winch, a steel wire rope is wound on the wire rope winch, a manned platform is connected to the bottom of the fixed protection box through a rope, and the shaft center of the wire rope winch The crankshaft is fixedly connected at the position, and the end of the crankshaft is connected with the fixed protection box through bearings; cylinders are respectively fixed in the corresponding fixed protection boxes on both sides of the wire rope winch, and a positioning turntable is fixed in the corresponding fixed protection box above the wire rope winch, and the inside of the cylinder is equipped with The piston; the bottom of the piston is connected with a connecting rod; the top of the cylinder is respectively connected with a high-pressure hose, and the end of the high-pressure hose is connected with a gas cylinder, and a fine-tuning air release valve is arranged on the gas cylinder. The invention can get rid of the dependence on energy sources, does not need energy consumption, has adjustable falling speed, does not generate impact force on the rope, realizes slow landing, is safe and reliable, and is convenient and flexible to use.

Description

technical field [0001] The invention relates to the technical field of high-altitude escape equipment, in particular to an unpowered rapid escape self-rescue device. Background technique [0002] With the continuous and rapid development of the national economy, the pace of urban construction is accelerating, and the building land is increasingly tense, making buildings develop to high altitudes. The number of high-rise and super high-rise buildings in the city is increasing, making the fire safety situation of urban high-rise buildings more and more severe. . In recent years, examples of high-rise and super high-rise building fires in some cities reflect that the reality is not optimistic: the number of annual occurrences is large, the economic loss is heavy, the casualties are large, and the social impact is deep, etc., and there is a trend of increasing year by year, which has become an important problem that needs to be solved urgently. [0003] In high-rise buildings, ...

AI Technical Summary

Problems solved by technology

[0004] In the prior art, the escape self-rescue device needs to rely on external energy such as electric energy to ensure its normal operation. However, when a fire occurs, the power will often be cut off, and the safety and reliability cannot be effectively guaranteed. In addition, the landing of the existing escape device The speed is fixed and cannot be adjusted, especially the landing speed is very fast, it cannot achieve a slow landing, it is likely to cause some damage to the survivors, and it is not flexible enough to use
