Life saving device for high building

Abstract

The invention discloses a high-rise escape device, which comprises a chassis, a roller of which the center is provided with a gear shaft and a steel cable wound outside the roller, wherein the gear shaft is connected with a centrifugal frictional braking body into a whole through a key in the roller of which one end face is provided with a centrifugal frictional brake, the centrifugal frictional braking body evenly distributes 1 to 6 shaft holes on the circumference which uses a shaft axis of the gear shaft as the center of a circle, and the large circular arc of a brake block which is wound on the shaft holes and is rotated by the shaft is matched with the curvature of the inner diameter of a centrifugal frictional brake drum. The high-rise escape device has the advantages of simple structure, good manufacturability, no need of electrical power and energy and extremely high reliability. The popularization and the application of the high-rise escape device can greatly improve life security when high-rise people suffer from accidents.

Description

technical field [0001] The invention relates to a lifting device for a building, in particular to a high-rise escape machine that helps people descend from a high place to a low place and escape from the scene when a fire or an earthquake occurs. Background technique [0002] Harmonious society, people-oriented. When the World Trade Center in New York was attacked by terrorists, in 2008 when the Longgang fire occurred in Shenzhen, and when the student dormitory of a certain college in Shanghai was on fire, many precious lives were lost because there was no corresponding equipment to escape from high-rise buildings. [0003] At present, there are high-rise escape machines in the world, such as the United States, Japan, and Taiwan, which all have products for sale, but they all use electricity to control the operation of the machines. In the event of a fire or earthquake, the site is generally cut off, making it unusable. The use of batteries has the problem of daily mainten...

In the event of a fire or earthquake, the site is generally cut off, making it unusable

The use of batteries has the problem of daily maintenance. After the machine is installed, it may not be used for decades. The cost of maintenance cannot be afforded by consumers, and the market is difficult to implement.

In the world, there is a pulley-combined descending device used by mountaineers, which uses ropes to control the descent. This kind of descending device requires training for personnel to use, and it is difficult to promote in the market, and the safety factor is too low. The relevant national departments do not allow it to be promoted as a Escape equipment for preventing fire and earthquake
