High-rise safety escape device

Abstract

The invention discloses a high-rise safety escape device. The high-rise safety escape device comprises a shell, an acceleration reverse brake planet gear system, a centrifugal expansion brake module, a rope winding drum and a center rotating shaft, wherein the acceleration reverse brake planet gear system, the centrifugal expansion brake module, the rope winding drum and the center rotating shaft are arranged in the shell. The high-rise safety escape device is skillful and reasonable in structure design and small in size; as a brake gear in the acceleration reverse brake planet gear system is in interference fit with a mounting shaft, the friction force is high, and the descending speed is effectively reduced; meanwhile, the centrifugal expansion brake module performs double high-speed reverse rotation along with the center rotating shaft under driving of the acceleration reverse brake planet gear system; a brake block is thrown out and ejected against the rope winding drum through the effect of centrifugal force, so that the friction force is effectively increased, the damping effect is good, the descending speed is further reduced, and the use is safe and reliable; and no manual control is needed in the descending process, so that the operation is simple and convenient, the application range is wide, and the high-rise safety escape device can be used for fire rescue, speed damping, altitude escape in public places and safety protection of aerial operation or movement.

Description

technical field [0001] The invention relates to the technical field of lifesaving in water, in particular to a high-rise safety escape device. Background technique [0002] Fire has brought more and more threat to people's life and property safety, especially for the resident of high-rise building, once breaking out of fire will be difficult to escape. An escape device that helps people escape smoothly can save many lives. [0003] There are few types of existing building escape devices, usually equipped with high-power motors and variable speed and control devices, which are expensive, bulky, heavy, inconvenient to carry and use, and the effect of saving people and escaping needs to be improved. For this reason, the crowd living in the high-rise building is badly in need of a kind of emergency escape tool that is safe and convenient, without power, power supply, and pure machinery to escape from the scene of fire quickly. Contents of the invention [0004] In view of th...
