High-rise building descent control device

Abstract

The invention discloses a high-rise building descent control device. The high-rise building descent control device comprises a rope (1), a rope hook (2), a hook ring (3) and a rope winding part (4), the rope (1) is in a round table series-connection shape, and an upper handrail (5) and a lower handrail (6) which are in threaded connection with each other in the up-down direction closely penetratethrough the rope (1) in a sleeving mode; the upper end of the lower handrail (6) is provided with a plurality of tower shape outer threads split in the up-down direction, and the lower end of the upper handrail (5) is provided with an inner thread; and an anti-separating-and-falling-off ring (7) is arranged between upper handrail (5) and the lower handrail (6), the rope winding part (4) takes foamed plastic as a dustproof cover (8), and the dustproof cover (8) becomes a flat-plate-type parachute in the downward-throwing process. In the downwards-sliding process of a survival person along the rope (1), the downwards-sliding speed is controlled by means of adjusting the combination tight degree of the lower handrail (6) and the rope (1), and it is ensured that the survival person steadily and slowly descends to the ground or a security level without wear to skins of both hands of the survival person.

Description

technical field [0001] The invention belongs to a fire-fighting appliance, and more specifically relates to a slow-descending device for high buildings. Background technique [0002] Personnel in tall buildings, when a fire breaks out, will unavoidably have to slide their hands and feet down the ropes from the window to the ground or a safe level to survive. During this process, the skins of their hands are often worn or heated by the ropes and cannot continue to slowly descend. , therefore, it is of great significance to provide a descending device. Contents of the invention [0003] The purpose of the present invention is to provide a kind of slow-down device for tall buildings. [0004] The present invention is a slow descending device for tall buildings, which includes a rope, a rope hook, a shackle, and a rope winding part. The rope is in the shape of a circular platform in series, and the rope is tightly sheathed with an upper hand and a lower hand that are screwed ...
