Fire-fighting escape device

Abstract

The invention discloses a fire-fighting escape device. The fire-fighting escape device structurally comprises a descent control device, a safety hook, a descent control rope, a rolling wheel and a safety belt, the outer surface of the descent control device is provided with a slide way, and the descent control rope is wound around the outer circumferential surface of the descent control device and extends to be connected to the rolling wheel. According to the fire-fighting escape device, planetary gear sets are arranged inside the descent control device correspondingly to cooperate with auxiliary planetary gears, the planetary gear sets rub against a rotating shaft through friction blocks to achieve constant-speed descent of the descent control device, when the friction blocks are ground flatly, stress blocks are exposed on the outer surface to be meshed with the rotating shaft, on the basis of the former situation, the stress blocks and jacking force rods cooperate with elastic force tension springs and push rods to jointly act on movable blocks to enable the movable blocks to be horizontally pushed into buckling plates, then buckling guide wheels which are buckled and fixed at the tail portions of the buckling plates are pushed out, so that the auxiliary planetary gears are popped out to replace the planetary gear sets to complete the meshing work, then the descent control device can continuously keep constant-speed descent, and the safety problem caused by the fact that the descent control device loses efficacy before a user arrives at the ground is solved.

Description

technical field [0001] The invention relates to the technical field of fire fighting, in particular to a fire escape device. Background technique [0002] With the development of social economy and the acceleration of urbanization, high-rise office buildings, hotels, business centers and other public buildings have sprung up one after another, but at the same time, the safety problems of high-rise buildings are also increasingly exposed. In view of the serious casualties caused by fires in high-rise buildings, in response to this situation, a lot of equipment for fire escapes have emerged in the current market to improve the effectiveness and success rate of fire escapes. Commonly used fire escape facilities There are slow-down devices, life-saving air cushions, life-saving slides, roof slow-down devices, emergency rescue baskets, etc. Among them, the slow-down device is mainly for personal use, and its structure is composed of governors, safety belts, safety hooks, wire rop...

AI Technical Summary

Problems solved by technology

[0003] The existing technology mainly uses the friction generated by the friction block to achieve the function of slowing down, but the slow down caused by the friction is easy to wear with the friction when the high-rise building is used, and the friction in the friction block is gradually reduced or even smoothed, so that The friction block has completely failed before reaching the ground, so that the descender cannot descend at a uniform speed, which affects the safety of use
