Escapement type high-rise fast-downing and escaping backpack

Abstract

An escapement type high-rise fast-downing and escaping backpack comprises a backpack body, a fixing support, a rope sheave, an escapement device and a sliding-down rope, wherein the fixing support is fixedly mounted in the backpack body; two fixing plates which have the same structure are symmetrically arranged and are fixedly supported through fixing screws; the rope sheave and the escapement device are mounted between the two fixing plates; the rope sheave and the fixing support form a pulley mechanism; the rope sheave and the escapement device are mounted in a transmission fitting manner; the sliding-down rope coils the rope sheave; one end of the sliding-down rope is fixedly connected to the rope sheave while the other end of the sliding-down rope is fixedly equipped with a hook. The escapement type high-rise fast-downing and escaping backpack has the beneficial effects that the backpack is integrally arranged, so that the convenience of storing is ensured; the backpack can be used once after being taken out, thus the escaping speed is increased; an escaper can shoulder the backpack and hang a solid fixed matter through the hook at the end head of the sliding-down rope and then can slide and down from a window, and other operations are not needed, so that the operation is simple; the escaper and the backpack slide down together at constant speed; the sliding-down rope can automatically recoil in the backpack while the rope sheave rotates, and outside interference is avoided, so that the sliding-down safety is ensured.

Description

technical field [0001] The invention relates to an escape device for rapid descent from a high building, in particular a back-carry escape backpack for rapid descent from a high building based on the principle of escapement. Background technique [0002] With the increase of building height in urban construction, it brings extremely high difficulty to fire evacuation. On the one hand, when a fire breaks out, the structure of the high-rise building is complex and closed. Due to the chimney effect, the smoke and fire spread quickly, which may easily block the fire exits; on the other hand, the high-rise buildings are densely populated and there are few auxiliary means of escape. Once the crowd cannot be evacuated in time, the consequences will be extremely serious. Existing building fire evacuation is mainly evacuated through fire stairs, but when a fire occurs in a high-rise and the fire area is large, the fire exits are easily blocked by the fire, and the influence of smoke...
