Non-mechanical friction damping automatically controlling speed method and device thereof thereof

Abstract

The invention discloses a non-mechanical friction damping automatic speed control method and a device thereof, the method is that: a cable wheel which is wound by a cable is mechanically linked with a fluid damping mechanism or an electromagnetic damping mechanism; the device is composed of the cable, the cable wheel, a speed change device, the fluid damping mechanism or the electromagnetic damping mechanism, the cable is serially wound on the cable wheel, a shaft of the cable wheel is linked with a power input shaft of the speed change device, a power output shaft of the speed change device is linked with a rotating shaft of the fluid damping mechanism or the electromagnetic damping mechanism, and the whole device is mounted at the fixed position by a mounting ring on an outer shell. The device can allow the speed of an escaper or a high-altitude operator during the descending process to be automatically controlled within the safe range when a high-rise building has a fire hazard, the mechanical friction parts of the device are fewer and the stability of the speed control is better.

Description

technical field [0001] The invention relates to a speed control method and a device adopting the method, in particular to a non-mechanical friction damping automatic speed control method and a device thereof. Background technique [0002] How people escape safely when a fire breaks out in a high-rise building is a problem that has not been well resolved so far. People have devised a lot of methods for escaping from high-rise buildings when a fire broke out, among which safe passage is the most commonly used method. But in fact, the flames and toxic smoke in the fire often permeate the corridors and safe passages leading to safe passages. It is difficult for panicked escapees to find safe passages in the thick smoke with extremely low visibility. This tragic case Too many to list. The most direct reaction of some trapped people is to flee to windows or balconies to call for help and try to escape. People who cannot endure the engulfing flames just jump from windows or balco...

Problems solved by technology

In fact, this is impossible, because many of the escapees are frail old people, children and the injured. Whether it is mental state or physical strength, self-control ability or operation technology, it is difficult for a panicked escapee to survive. Operate such devices calmly and efficiently to escape

Moreover, these devices almost all rely on mechanical friction to limit the speed, because the size of the mechanical friction varies with various unstable factors such as the material of the friction parts, the surface physical properties, the pressure between the friction parts, the ambient temperature, and the humidity. Changes, poor stability, so this type of escape device that relies on mechanical friction damping to limit speed is not safe

[0004] In addition, some high-altitude operations and military activities also require practitioners to frequently descend from high altitudes. Although they have the ability to control their descent speed, they must operate and control their descent speed while performing professional work. Accidents do happen
