Abstract

The invention discloses a hydraulic-deceleration high-rise fire protection escape device. The hydraulic-deceleration high-rise fire protection escape device is composed of leg protecting bands, a waist fastening band, connecting bands, grips, deceleration handles, hydraulic brake pumps, piston thrust devices, tension springs, air duct discs, isolation rings, a Kevlar fireproof fiber rope, safety suspension clasps, hydraulic tubes and friction plates. The escape device realizes gravity-driven rope pay-off and hydraulically-controlled deceleration, decelerated descending is controlled in real time by holding the deceleration handles in hands, and the requirements for deceleration, continuous operation, easy and convenient operation and safety and reliability are met.

Description

technical field [0001] The invention relates to a high-rise fire escape device for hydraulic deceleration, in particular to a high-rise fire escape device for real-time hydraulic deceleration control. Background technique [0002] With the development of the times and the effective use of land, the construction of high-rise buildings has become inevitable, and this has higher requirements for the fire protection devices of high-rise buildings. The problem of escaping when a fire broke out in a high-rise building has always been a technical problem. In the past, when a fire broke out, the firefighters usually carried the ladder to rescue the affected people. This method is not only inefficient, but also accompanied by high danger. Some existing escape devices cannot be popularized for reasons such as high price, complicated operation, impracticality, and instability. So research and develop a kind of safe and reliable, easy and simple to operate, even cheap high-rise fire e...
