High-rise emergency escape slow descent control device for smart city and using method of high-rise emergency escape slow descent control device

Abstract

The invention discloses a high-rise emergency escape slow descent control device for a smart city and a use method of the high-rise emergency escape slow descent control device, and particularly relates to the field of smart cities. The high-rise emergency escape slow descent control device comprises a balance weight stabilizing seat and supporting side plates, wherein pay-off guide wheels, the supporting side plates and a working machine case are fixedly installed on the top surface of the balance weight stabilizing seat; and rotary crankshafts are rotatably mounted in the working machine case, cable winding rollers fixedly sleeve the outer sides of the rotary crankshafts, a bearing seat is fixedly mounted on the inner side of each supporting side plate, the ends of the rotary crankshaftsrotatably sleeve the bearing seats, and a hydraulic slow descent mechanism is fixedly mounted in the working machine case. According to the high-rise emergency escape slow descent control device, byarranging a hydraulic slow descent structure, partial rotating mechanical kinetic energy of a reel is consumed through flow limiting movement of hydraulic oil liquid in the hydraulic slow descent mechanism and a hydraulic adjusting mechanism, so that the slow descent purpose is achieved, the hydraulic slow descent mode is more stable compared with friction speed reduction, and the safety of slow descent escape is greatly improved.

Description

technical field [0001] The present invention relates to the technical field of smart cities, and more specifically, the present invention is an emergency escape slow-down device for high-rise buildings used in smart cities and its usage method. Background technique [0002] With the development of smart cities, the scarcity of land resources, and the improvement of economic and consumption levels, large shopping malls and commercial centers have sprung up one after another, and the development of high-rise buildings is extremely rapid, and the number has increased sharply. The number of fire accidents is also increasing, and more importantly, as the height of buildings increases, the difficulty of fire rescue work increases sharply, especially the fire rescue of high-rise and super high-rise buildings has always been a worldwide problem. There has not been a comprehensive and good solution. The ability of high-rise building fire rescue has become an important symbol to measu...

Problems solved by technology

[0004] The existing slow down device mainly uses frictional deceleration to slow down, and uses the friction between the brake pad and the grinding disc to limit the speed of the reel. In actual use, the degree of fit between the brake pad and the grinding disc is difficult to control and difficult to adjust the slow down. speed, it is inconvenient to use in the process of emergency escape, and the brake pads are prone to vibration during the friction process. If the fixation is not firm, it is easy to cause friction and separation, causing safety accidents
