Large escape slow-descending device

Abstract

The invention provides a large uniform-speed escape slow-descending device capable of being used by many people. The slow-descending device is mainly composed of a base with a shifting-out mechanism, a supporting rack, a cage, a suspension mechanism, a slow-descending mechanism, a track releasing mechanism, a clutch mechanism, a cage withdrawing mechanism and the like, wherein the supporting rack of a steel structure can be moved out through the shifting-out mechanism on the base; the slow-descending mechanism and a track rope wheel is installed on the supporting rack; the hand wheel of the track releasing mechanism is rolled to put down a track; and escape people enter an escape cage and descend a handle to realize the descending and escaping purposes. The device adopts the deceleration principle that the speed is accelerated through a planet wheel, so that a friction block generates a centrifugal force and a friction force with a shell to slowly descend. The slow-descending device has the characteristics of simple operation, stable descending speed, small occupation area, simple and practical structure as well as safety and reliability.

Description

technical field [0001] The invention provides a large reciprocating life-saving slow-down device that can be used by multiple people, is simple to operate, safe and reliable, and belongs to the technical field of high-rise life-saving devices. Background technique [0002] At present, with the accelerated pace of urban construction, urban land is becoming more and more tense, forcing humans to develop to high altitudes, and there are more and more high-rise buildings. However, as the proportion of people living in high-rise buildings increases, once unpredictable emergencies such as fires occur , Earthquakes and the like, traditional rescue devices for firefighters such as ladders, air cushions and other escape devices cannot make high-rise residences and people in office buildings evacuate quickly and safely. Existing small-sized personal life-saving descending device is characterized in that it is flexible, but there are few people transported at one time, and the efficien...

Problems solved by technology

[0002] At present, with the accelerated pace of urban construction, urban land is becoming more and more tense, forcing humans to develop to high altitudes, and there are more and more high-rise buildings. However, as the proportion of people living in high-rise buildings increases, once unpredictable emergencies such as fires occur Earthquakes and the like, traditional rescue devices for firefighters such as ladders, air cushions and other escape devices cannot enable people in high-rise residential buildings and office buildings to evacuate quickly and safely

The existing small life-saving descending device for personal use is characterized by flexibility, but it is less efficient to transport people at one time, and it can be used for personal escape, but it still cannot meet the requirements of many people's escape.
