Safety ladder for evacuation

Abstract

The invention discloses a safety ladder for evacuation. The safety ladder comprises a supporting frame, a plurality of sections of climbing ladders fixed to the side face of the supporting frame and connected end to end, and an airborne channel fixed to the side portion of the supporting frame, wherein the top of the supporting frame is provided with a hoisting device used for suspending goods, agoods hoisting channel for allowing the goods to be vertically hoisted is arranged in the middle of the supporting frame, an airborne safety backpack is arranged at the upper portion of the airborne channel, the airborne safety backpack comprises a backpack body with at least two shoulder straps, an airborne rope arranged in the backpack body and a damping device used for providing a damping effect for the airborne rope to stretch out of the backpack body, and the damping device comprises a reel used for winding the airborne rope, a speed increaser used for increasing the rotating speed of thereel and a rotary damper used for exerting a damping effect on an output shaft of the speed increaser. The safety ladder is used for rapidly evacuating people in emergency accidents of multi-storey buildings such as superstores.

Description

Technical field [0001] The invention relates to the field of safety engineering equipment, in particular to a safety ladder for evacuation. Background technique [0002] With the rapid development of urban construction, large shopping malls are becoming more and more common in cities. However, fire rescue problems for multi-storey buildings such as shopping malls have gradually emerged. Due to their high floors, large volumes, densely populated people, fewer evacuation stairs, and emergency situations such as fires and earthquakes, it is difficult to quickly respond to personnel The consequences of evacuation are disastrous. At present, some fire escape tools are gradually appearing on the market, such as fire escape ladders, emergency fire-resistant life-saving ropes, steel wire ropes, etc. These products have their own different defects. [0003] Therefore, there is an urgent need to develop a safety ladder for evacuation of people in emergency accidents in large shopping malls ...

AI Technical Summary

Problems solved by technology

However, the problem of fire rescue for multi-storey buildings such as shopping malls has gradually emerged. Due to its high floor, large volume, dense population, and few evacuation stairs, it is difficult to quickly rescue personnel in case of fire, earthquake and other emergencies. The consequences of evacuation are unimaginable. At present, some fire escape tools have gradually appeared on the market, such as fire escape ladders, emergency fire-resistant lifelines, steel wire ropes, etc. These products have different defects.
