High-rise escape system

Abstract

The invention provides a high-rise escape system. The high-rise escape system comprises a load system, a differential speed system and a control system, wherein the load system comprises a reel and a steel wire rope, a driving gear is arranged at one end of the reel, the steel wire rope is wound around the reel, and the two ends of the steel wire rope are connected with lift cars correspondingly; the differential speed system comprises a differential mechanism and a loop gear, and the loop gear is connected with two input shafts of the differential mechanism; and the control system comprises a gear set connected with an output shaft of the differential mechanism and an escapement mechanism connected with the gear set. The high-rise escape system needs no external power, and is simple in structure, easy to process and manufacture, large in payload, high in collective escape and rescue efficiency, long in service life and low in maintenance frequency, and component materials are common and easy to obtain.

Description

technical field [0001] The invention relates to the technical field of high-rise escape, in particular to a high-rise escape system. Background technique [0002] In recent years, with the growth of China's economic strength, high-rise buildings have sprung up. According to statistics, there are about 220,000 high-rise buildings in China. Generally, the height of 24 meters to 150 meters is called high-rise buildings. For super high-rise buildings, the proportion of super high-rise buildings is less than 1%, which means that the vast majority of urban people work and live in high-rise buildings between 24 meters and 150 meters. Therefore, it is an urgent demand and has a huge market prospect to research reasonable and efficient rescue and escape equipment and programs for high-rise buildings in this range when a fire breaks out. [0003] At present, the main high-rise fire escape measures at home and abroad are as follows: [0004] 1. Personal Descent Device [0005] As a ...

AI Technical Summary

Problems solved by technology

[0014] 1. The personal descending device is for personal use, but there is no external protection, and it is easy to have fear. Considering the psychological factors and the influence of high-altitude wind, it is not suitable for the elderly, weak, sick and disabled, and only suitable for relatively low floors such as below 10 floors; and Can't pass through disaster zone

[0015] 2. The escape chute is used collectively and sequentially. It is difficult for people of different sizes and weights to guarantee a uniform speed, which is prone to collisions and stampedes. It is not suitable for hospitals and the elderly; long-term contact with the outside world requires high material life; it cannot pass through disasters. Area

[0016] 3. Outdoor rescue cabins and escape elevators need external power, and when a general fire occurs, the power is cut off; if a non-electric power device (such as a diesel engine) is used, the entire system is very complicated and it is difficult to ensure that it can work normally in real time

[0017] 4. High-rise slow-descent device At present, among the domestic high-rise slow-descent devices, only the high-rise rotor developed and produced by Beijing Nuoanzhou Emergency Slow-descent Machinery Co., Ltd. Type slow-down escape cabin, its disadvantage is that the load is small, the efficiency is low, it needs to be fixedly installed on the roof or the refuge floor, and the personnel are evacuated in a centralized manner; the equipment is complex and the transmission is precise; the equipment is expensive (200w / unit);

[0018] In the current high-rise building escape technology, there is no escape device that takes into account collective escape, floor height, escape efficiency, and easy-to-accept price
