High-rise escape descent control device

Abstract

The invention discloses a high-rise escape descent control device. The device comprises a rear plate, connecting columns, a central shaft, a rope wheel, a rope, a rotary damping mechanism, a rope guide assembly, a front plate and a fixing frame; the three connecting columns are fixedly mounted at the top end of the front side and the middle positions of the left side and the right side of the rear plate correspondingly; the central shaft is rotatably mounted in the middle of the front side of the rear plate; the rear end of the central shaft is sleeved with the rope wheel in a matched mode; the rope is wound on the outer wall of the rope wheel; the rotary damping mechanism is mounted in the middle of the front side of the front plate; the rope guide assembly is mounted at the bottom end of the front side of the rear plate; the front plate is mounted at the front ends of the three connecting columns and the rope guide assembly; and the fixing frame is connected to the middle position of the outer wall of the connecting column located at the top end in a sleeving mode. According to the high-rise escape descent control device, the rope can be controlled to be released stably and slowly, the higher the rotating speed is, the larger the rotating damping coefficient is, the effect of controlling the rotating speed is achieved, the purpose of safe escape is achieved, the structure is simple, maintenance is convenient, the rope can be prevented from being abraded, and certain potential safety hazards are prevented.

Description

technical field [0001] The invention relates to the technical field of high-rise escape tools, in particular to a high-rise escape descent device. Background technique [0002] The escape descent device is a safety rescue device that allows people to descend slowly along the rope. It can be installed on windows, balconies or flat roofs of buildings with special installation equipment, and it can also be installed on elevating fire trucks to rescue victims in high-rise buildings; [0003] At present, there are some escape slow descenders on the market, whose damping effect is not good, and most of them are decelerated by planetary wheels or brake mechanisms, etc., and the damping coefficient is not linearly proportional to the descending speed, which cannot achieve the purpose of safe escape, and the escape slowdown with a relatively complicated structure The descender is expensive and difficult to maintain. In addition, there is no rope guide device, and the friction betwee...
