A multi-storey building escape reducer

Abstract

The invention provides a multi-storey building escape reducer, which relates to the technical field of multi-storey building safety evacuation, including: a descending system, a roller track, and a buffer system; the descending system includes: a roller, a rotating shaft, and a descending belt. Fixed connection, the first end of the landing belt is fixed on the rotating shaft; the buffer system includes: a connecting part, a shaft body, and a buffer cylinder. The middle section of the shaft body is embedded in the buffer cylinder and is fixedly connected with the buffer cylinder. It is movably connected with the connecting part; the roller is placed in the roller track, and the connecting part is fixed on the roller track. The invention has the advantages of simple structure, low cost and high safety, can effectively avoid the unsafe situation caused by the excessive speed of the escape personnel when they land, and has a good protective effect on the escape personnel.

Description

technical field [0001] The invention relates to the technical field of safe evacuation of multi-storey buildings, in particular to an escape reducer for multi-storey buildings. Background technique [0002] With the development of social economy, the number of urban buildings is increasing day by day. When catastrophic accidents such as fires and earthquakes occur, whether multi-storey buildings can realize rapid and safe evacuation of personnel has become a key concern of people. Simply relying on fire stairs and other common escape methods can no longer meet the needs. People need a safe, An escape method with low cost, simple operation and high efficiency of personnel evacuation. In the existing escape methods, the descending speed of the escaped personnel cannot be effectively controlled, especially when the personnel are about to reach the ground, the kinetic energy converted from the gravitational potential energy is relatively large, and the descending speed of the e...

When catastrophic accidents such as fires and earthquakes occur, whether multi-storey buildings can realize rapid and safe evacuation of personnel has become a key concern of people. Simply relying on fire stairs and other common escape methods can no longer meet the needs. People need a safe, An escape method with low cost, simple operation and high efficiency of personnel evacuation

In the existing escape methods, the descending speed of the escaped personnel cannot be effectively controlled, especially when the personnel are about to reach the ground, the kinetic energy converted from the gravitational potential energy is relatively large, and the descending speed of the evacuated personnel is relatively high. The damage suffered by small people reaching the ground, but its safety is still not well guaranteed
