High-rise escape self-saving

Abstract

The invention discloses a high-rise escape self-saving pin, which is characterized in that a steel cable is composed of 1 to 6 damping tubes. The damping tube has a steel pipe of which a left end and a right end are respectively in threaded connection with a left end cover and a left side opening of a safety valve, a right side opening of the safety valve is connected with a right end cover, the steel cable penetrates into the steel pipe from the center of the left end cover, then through the centers of U-shaped bolts of 11 to 22 steel cable clamps arranged inside the steel tube and finally out of the right end cover through the safety valve, two ends, i.e. head and tail ends, of the steel cable are connected with a safety hook respectively, a plurality of disk-shaped springs are arranged between a base and a nut of the steel cable clamp, a square bayonet at the center of a hand wheel is sleeved on a tetragonal prism at the upper part of a screw rod in a manner of clamping, a fixing nut is arranged above the screw rod and the hand wheel, an I-shaped head of the lower end of the screw rod is inserted into a round hole of a U-shaped press head, and a positioning pin passes through, from left to right, the middle space between the U-shaped press head and the I-shaped head which are sleeved together. The high-rise escape self-saving pin is stable in operation, simple, reliable, high in escape opportunity and excellent in smoke / flame resistance.

Description

technical field [0001] The invention relates to a device for self-rescue in case of fire, in particular to a high-rise escape self-rescue bolt. Background technique [0002] With the acceleration of the urbanization process, there are currently 160,000 high-rise buildings in my country, and the equipment for escaping and self-rescue in the event of a fire in high-rise buildings has gradually attracted attention. After inquiry, there are more than 30 relevant patents at home and abroad in recent years; Italy and other countries also used helicopters for fire fighting and rescue. These large and medium-sized rescue and escape equipment can play a key role in certain specific occasions. The disadvantage is that the cost is high, and the scope of application is restricted by conditions. For example, in the Shanghai 11.15 catastrophic fire accident, the helicopter could not come close to carry out rescue due to the huge fire and fire. [0003] There is also a class of small es...

AI Technical Summary

Problems solved by technology

The existing disadvantages and deficiencies are as follows: 1. Some escape devices are bulky, and now urban buildings are expensive, and it is an expense to occupy a large space for a long time

2 There are problems and deficiencies in the stability and reliability of some escape devices, which are still far from practical requirements

3Each escape device can only escape one person at a time
