High-rise escape device capable of adjusting speed easily

Abstract

The invention discloses a novel high-rise escape device. The novel high-rise escape device comprises a rope-winding device, a hydraulic passage device, a connecting device and a clamping device, wherein the rope-winding device and the hydraulic passage device is fixedly connected to the upper part of the clamping device; and the rope-winding device is connected with the hydraulic passage device through the connecting device. The novel high-rise escape device adopts a pure mechanical structure device and has the advantages of light weight, flexibility, simple operation and capacity of excellently fulfilling a high-rise escape task in the period of a fire disaster. An escape rope is wound on a shaft, and drives a main shaft to rotate in a descending process; the main shaft drives two hydraulic cylinders to do straight reciprocating motion through a crank sliding block mechanism in a rotating process; a passage which is filled with liquid is formed by the two hydraulic cylinders, a damping pipe and a valve; the liquid does reciprocating motion along with the motion of pistons of the hydraulic cylinders; the liquid flows through a damping sheet and the valve during the motion; and the flowing speed of the liquid in a flowing process is controlled well through the damping action of the damping sheet and the flow limiting action of the valve, so that the aim of slowing down the descending speed is fulfilled.

Description

technical field [0001] The invention relates to a high-rise escape device, in particular to an easy-speed adjustable high-rise escape device. Background technique [0002] With the accelerated development of urban modernization, there are more and more high-rise buildings. At the same time, dangers such as high-rise fires often occur. Escape from high-rise buildings is a problem that people have to face, and personal safety protection is the top priority. People living in high-rise buildings often can only delay the time as much as possible and passively wait for rescue when the fire comes. In this process, the fire situation may endanger their lives at any time. Faced with this situation, people have thought of utilizing devices to escape from windows, and therefore a series of high-rise escape equipment have also been born both at home and abroad. [0003] After searching, it is found that many high-rise escape devices at home and abroad have been successfully developed ...

AI Technical Summary

Problems solved by technology

[0009] It can be seen from the above that in the field of high-rise escape equipment, dry friction is mainly used to control the speed. After a long time of use, serious wear and tear will inevitably occur. At the same time, some escape equipment with better effects are extremely expensive and inconvenient to operate.
