Portable high-building self-help instrument

Abstract

The invention discloses a portable high-rise self rescue apparatus which mainly consists of a shell as well as a cable wire, a wire wheel that is provided with an internal wheel, a gear increaser, a centrifugal wheel, a lever type centrifugal block and a centrifugal sleeve that are assembled in the shell; the cable wire is wound on the wire wheel, one end of the cable wire extends out of the shell and is fixed on a steel hook, the internal wheel of the wire wheel transmits the gear increaser, a final stage gear of the gear increaser and the centrifugal wheel are fixed on a centrifugal wheel axle, the lever type centrifugal block is fixed on the centrifugal wheel by a shaft pin, and the centrifugal sleeve which generates centrifugal acting force and reaction force together with the lever type centrifugal block is fixed on the shell. The structure is convenient and safe for use, and can automatically control the descent speed.

Description

technical field

[0001] The invention relates to a high-rise self-rescue device, in particular to a structure of a high-rise self-rescue device which can control the speed automatically or manually. Background technique

[0002] In modern cities, many residents will live, work or play in high-rise buildings. For some reason, if there is a fire that happens once in a lifetime, there is no very powerful tool that can independently save and escape. The consequences are unimaginable. Many fires have caused a large number of casualties.

[0003] There are many ways to escape from high-rise buildings in the society, such as slanting rope escape, which uses a long rope to tie one end of the building in danger, and the other end of the rope is tied to a stress point below or pulled by a car to form a A slope; another example is to use a rope to pull a basket to escape; and use an air cushion to let people in distress jump off a building to escape... All of the above escape methods m...
