Hydraulic resistance type tall building escape device

Abstract

The invention discloses a hydraulic resistance type tall building escape device, comprising a revolving axle, a damping rotor sheathed on the revolving axle and a winding reel sheathed on the damping rotor; wherein the two ends of the damping rotor and the two ends of the winding reel are all fixedly connected with a cover plate by virtue of bolts, the winding reel is wound with a steel wire rope used for escaping, the two ends of the winding reel and corresponding position on the cover plate are provided with a winding hole used for tying the steel wire rope, the cover plate is sheathed on the revolving axle by virtue of an axle sleeve and a rolling bearing contained in the axle sleeve, the cover plate is fixedly connected with an end cover by virtue of bolts, the revolving axle is provided with a seal ring used for sealing the revolving axle, the axle sleeve and the damping rotor, the two ends of the revolving axle are fixedly connected with a hook, and a hermitical space formed by the revolving axle, the damping rotor, the winding reel and the seal ring is injected with viscous liquid. The invention has compact structure, novel and reasonable design, operation convenience, high stability, durability and reliability, good cyclic utilization performance, low cost and strong practicability and is beneficial to popularization and application.

Description

technical field [0001] The invention relates to a high-rise escape device, in particular to a liquid resistance type high-rise escape device. Background technique [0002] With the increasing development of social economy, the continuous acceleration of urbanization process and the continuous improvement of people's living standards, there are more and more high-rise buildings such as high-rise commercial buildings, office buildings, and residential buildings, and the floors are built higher and higher. When earthquakes or other disasters cannot escape from stairs or elevators, and there is no safe place to hide, they can only wait for the rescue of others, and sometimes they will be injured by disasters due to the slowness of rescue. Therefore, a safe, reliable, A convenient high-rise self-rescue escape appliance. At present, in the prior art, the vast majority of high-rise escape devices use the principle of friction, that is, the friction between objects is used as the s...

Problems solved by technology

[0002] With the increasing development of social economy, the continuous acceleration of urbanization process and the continuous improvement of people's living standards, there are more and more high-rise buildings such as high-rise commercial buildings, office buildings, and residential buildings, and the floors are built higher and higher. When earthquakes or other disasters cannot escape from stairs or elevators, and there is no safe place to hide, they can only wait for the rescue of others, and sometimes they will be injured by disasters due to the slowness of rescue. Therefore, a safe, reliable, Easy-to-use high-rise self-rescue escape appliance

At present, in the prior art, the vast majority of high-rise escape devices use the principle of friction, that is, the friction between objects is used as the source of resistance of the escape device. Although it can initially solve some problems of high-rise escape, the friction force is difficult. Dynamic adjustments are made according to the whereabouts of the human body, and it is difficult to achieve the stability of the human body when it falls; moreover, there is a close relationship between the friction force and the interacting medium, and the escape device using the friction principle will lose its relative friction surface after repeated use will change, which will seriously affect the durability and reliability of the escape device
