Large capacity high-rise escape device

Abstract

The invention relates to a large capacity high-rise escape device, which comprises an upper belt pulley (1), a force transfer rod (2), a carrying basket (3), a conveyor belt (4), a lower belt pulley (5), a mechanism assembly (6), a lower buffer spring (7), an adjusting spring (8), a damping oil tank (9), a friction plate (10), a friction wheel (11), an upper buffer spring (12), a rack (13), a high-speed gear (14), a high-speed shaft (15), a low-speed shaft (16) and a low-speed gear (17). A large amount of escape personnel can be conveyed to the ground from the high-rise through a conveying mechanism; and the conveying speed can be automatically adjusted according to the number of the escape personnel through an automatic speed adjusting mechanism to ensure that the personnel out of danger escape the high-rise at a safe and stable speed. The device has the advantages of large capacity, automatic adjustment of speed, safety, reliability and no need of manual operation, and is suitable for comprehensive high-rises with dense population.

Description

technical field [0001] The invention relates to a high-rise escape device, in particular to a large-capacity high-rise escape device capable of automatically adjusting the speed, and belongs to the field of safety technology. Background technique [0002] With the rapid development of economy, society and science and technology, more and more people live and work in high-rise buildings. When fires and earthquakes occur, how to design excellent high-rise escape devices to allow trapped people to escape quickly and safely has become a problem that has attracted more and more attention. [0003] According to related data, the existing high-rise escape devices in China mainly include high-rise slow descenders, high-rise escape umbrellas, high-rise escape slides, new inflatable life-saving devices, and rope-wrapping column type escape devices. However, most of the high-rise descending devices are realized by using ropes and manual speed-regulating mechanisms. This type of escape...

AI Technical Summary

Problems solved by technology

However, most of the high-rise descending devices are realized by using ropes and manual speed-regulating mechanisms. This type of escape device is only suitable for a single trapped person, and at the same time has high requirements for the psychological quality of the escaped personnel; If it is used by one person, each person must be equipped with one at ordinary times, and some personnel cannot use it due to the influence of psychological factors. At the same time, due to the limitation of the floor, its scope of application is not wide; It is high and has high requirements on the flatness of the ground. The sharp objects protruding from the ground will pose a great threat to escape personnel, and its speed is not easy to control; The technical requirements for escape personnel are quite high, and the reliability is not high; high-rise escape pipe slides must be installed when building a building, and each floor needs this device. It has high cost, ugly appearance, and strict maintenance requirements. Buildings cannot be installed, which seriously limits its wide use
