Unpowered rapid escape self-rescue device

Abstract

The invention discloses an unpowered rapid escape self-rescue device. The device comprises a steel wire rope winch and a fixed protection box arranged outside the steel wire rope winch, a steel wire rope is wound on the steel wire rope winch, the bottom of the fixed protection box is connected with a manned platform through a rope, a crankshaft is fixedly connected to the axis of the steel wire rope winch, and the tail end of the crankshaft is connected with the fixed protection box body through a bearing; air cylinders are fixed to the two sides of the steel wire rope winch and correspond tothe interiors of the fixed protection boxes respectively, positioning rotary discs are fixed to the positions, corresponding to the interiors of the fixed protection boxes, above the steel wire rope winch, and pistons are matched and installed in the air cylinders; connecting rods are cooperatively connected to the bottoms of the pistons; and the top ends of the air cylinders are connected with high-pressure-resistant hoses respectively, the tail ends of the high-pressure-resistant hoses are connected with gas cylinders, and fine adjustment vent valves are arranged on the gas cylinders. The device can get rid of dependence on energy, does not need energy consumption, is adjustable in landing speed, cannot generate impact force on the rope, achieves 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
