Slow descent escape device

Abstract

The invention discloses a slow descent escape device. The slow descent escape device comprises a bottom plate and a back plate, a connecting seat is welded on one side of the top end of the bottom plate, a storage battery is fixedly arranged at the top end of the connecting seat, a controller is fixedly arranged at the top end of the storage battery, and a backpack sleeve is fixedly arranged on the rear end face of the back plate; cervical vertebrae protecting grooves are correspondingly formed in the middle of the top end of the backpack sleeve and the middle of the top end of the back plate,fixing rope rings are welded to the center connecting line at the front end of the back plate, a first pulley is arranged below the rope fixing rings, the middle of the front end of the first pulleyis movably connected with the front end of a rotating shaft through a bearing, and the rear end of the rotating shaft is fixedly connected with the front end of the back plate; and a second pulley isarranged at the position, away from the controller, below the first pulley, the middle of the front end of the second pulley is movably connected with the front end of a rotating shaft through a bearing, the rear end of the rotating shaft corresponding to the second pulley is fixedly connected with the front end of the back plate, and a third pulley is arranged below the second pulley. According to the slow descent escape device, people can be descended to the ground through a rope when resident building are in danger.

Description

technical field [0001] The invention relates to the technical field of disaster relief equipment, in particular to a slow-down escape equipment. Background technique [0002] At present, China's fire emergency rescue equipment capabilities are seriously out of balance with the rapid development of high-rise buildings. First, the equipment's height-lifting and long-range shooting capabilities are far behind the high-level development of high-rise buildings. The existing fire-fighting water tanker's water spraying capacity is only 8 floors. The height of the building, the highest lifting capacity of the ladder truck is only about 15 floors. For higher high-rise building fires, these emergency rescue equipment can only be "watching the tower and sighing"; Traffic and the environment around the building are seriously affected, and the opportunity is often delayed due to complex terrain and obstacles; third, the rescue capability of the equipment is poor. The existing ladder truc...

Problems solved by technology

[0004] 1. The binding structure of the human body is simple, which is easy to cause scratches and strangulation of the human body, and it is very easy for people to roll over in the air

[0005] 2. Most of the slow down equipment can only slow down but not slow up, and the use methods are relatively limited
