Fixed self-adaptive elastic force firefighting escape slow-descending system

Abstract

The invention discloses a fixed self-adaptive elastic force firefighting escape slow-descending system, which comprises a slow-descending device and a pulley mechanism, wherein the slow-descending device comprises a shell; a winding shaft and a speed regulating shaft are arranged in the shell; a self-adaptive rotating speed regulating mechanism is arranged on the speed regulating shaft; the self-adaptive rotating speed regulating mechanism comprises a movable ball disc which is fixedly arranged on the speed regulating shaft, a friction disc I which is sleeved on the speed regulating shaft, and a friction disc II which is arranged opposite to the friction disc I; a movable ball arm component is arranged on the side surface of the movable ball disc, which faces the friction disc I; friction surfaces which are matched with each other are arranged between the friction disc I and the friction disc II; a spring seat is arranged on the shell; a spring used for pressing the friction disc II on the friction disc I is arranged in the spring seat; a guide mechanism is arranged between the spring seat and the friction disc II; a transmission mechanism is arranged between the winding shaft and the speed regulating shaft; two winding discs are arranged on the winding shaft; the pulley mechanism comprises a pulley seat and a fixed pulley; two winding discs are connected with the fixed pulley through an escape rope; and the escape rope on the two winding discs has opposite winding directions.

Description

technical field [0001] The invention belongs to the technical field of fire-fighting equipment, in particular to a fixed self-adaptive elastic fire escape slow-down system. Background technique [0002] At the scene of an accident such as a fire, when the personnel of a high-rise building cannot evacuate through the fire floor to escape downstairs, it is necessary to use the slow-down device to implement the rescue of the personnel on the high-rise building. Existing slow-down devices are generally fixedly installed on building windows, balconies or flat roofs of buildings. When a disaster occurs and cannot be evacuated, people can use the slow-down device to escape. [0003] The existing slow-down device has a complicated structure and needs to use a power source. When a disaster such as a fire occurs, the high-rise building usually loses power, which leads to the failure of the slow-down device that needs to use a power source and cannot be effective. The operation of the...

Problems solved by technology

[0003] The existing slow-down device has a complicated structure and needs to use a power source. When a disaster such as a fire occurs, the high-rise building usually loses power, which leads to the failure of the slow-down device that needs to use a power source and cannot be effective. The operation of the slow descending device is complicated. When the elderly or children use the slow descending device to escape, they are prone to panic. Complicated operations will slow down the speed of escape. If the operation is wrong, new dangers will occur
