Description

High-rise self-rescue slow descending device

Technical field

The utility model is a kind of high-rise rescue instrument, relates in particular to a kind of high-rise building safe life-escape slow-falling device, allows people withdraw fast danger zone.

Technical background

Current increasing along with urban skyscraper, safe life-saving facility in building also more and more become building designers and wherein live, focus that staff pays close attention to: when running into the accidents such as blast, fire, there will be and can not remove the dangerous condition in time, rescue the situations such as indicator of trapped personnel, for this reason, high-rise self-rescue slow descending device seems particularly important.

The utility model high-rise self-rescue slow descending device is when application, can be fixed on the railing or balcony of building, when burst thing occurs to escape immediately, safety binding can be connected with steel wire rope, the personnel of saving oneself can tie up self on safety binding, under self gravitation effect, along steel wire rope, from eminence, decline, safe landing, rapidly escape.Leaving self-help apparatus can up reclaim rapidly automatically, meets next bit survivor.This device can be repeatedly used, and increases the possibility that in the short time, personnel as much as possible save oneself.

The content of utility model:

For the problems referred to above, the technical scheme that the utility model solves is: high-rise self-rescue slow descending device is comprised of rope drum mechanism, slow descending mechanism, rope recovering mechanism Ji Yasheng mechanism: rope drum mechanism is comprised of cylinder, left plate, right plate, circlip for shaft, soket head cap screw and rope, left plate is fixed on cylinder by circlip for shaft, right plate is fixed on cylinder by soket head cap screw, cylinder is arranged on main shaft by two bearings, and one end of rope is fixed on cylinder, slow descending mechanism is by ratchet, ratchet, pawl axis, circlip for shaft, friction plate, pressing plate, shaft coupling, butterfly spring, pad, the compositions such as round nut, ratchet is fixed on pawl axis by circlip for shaft, pawl axis is fixed on right plate, ratchet, friction plate, pressing plate, butterfly spring, pad, round nut is fixed on shaft coupling, shaft coupling is connected on main shaft by common round end flat key, when human body declines along rope, ratchet, ratchet and friction plate play drag effect, this resistance can be adjusted by round nut, make human body slow decreasing, the ground of arriving safe and sound.After human body arrives ground, just by rope recovering mechanism, worked, rope is regained, be beneficial to next survivor and use; Rope recovering mechanism is comprised of gear wheel, Large Gear Shaft and scroll spring, scroll spring one end is fixed on gear wheel, and one end is fixed in Large Gear Shaft, when human body declines, the moving gear wheel of little cingulum on cylinder rotates, scroll spring is tightened up, and when human body no longer declines, gear wheel stops tightening up scroll spring, contrary scroll spring loosens, gear wheel reverse rotation, reverses cylinder by the little tooth on cylinder, and rope is regained; In the process of regaining at rope, Ya Sheng mechanism works.Ya Sheng mechanism is comprised of rope guarding plate, spring, 2 spring shafts, and rope guarding plate and spring are arranged on respectively on spring shaft, and rope guarding plate is by the pressure of spring, push down rope, make the rope that reclaims fast entirely on cylinder, meet next bit survivor, improve escape efficiency.

This high-rise self-rescue slow descending device is sturdy and durable, weares and teares little, and the life-span is long; Can be repeatedly used, efficiency is high, is conducive to collective's escape; Simple in structure, volume is little, and resistance is adjustable, easy to use, smooth decreasing; This utility model can be widely used on various skyscrapers.
