Problems solved by technology

However, some of these escape devices have a short escape distance and cannot be used for escape from high-rise buildings; some are used for one-time escape.
[0004] Chinese patent CN200720139704.2 provides a slow-down device with hydraulic damping. Both ends of the hydraulic cylinder are connected through oil pipes, and a valve is set in the middle of the oil pipe to realize slow-down through the resistance generated by the flow of hydraulic oil in different sections. , but the structure of this

Embodiment Construction

[0023] Such as figure 1 Among them, a reciprocating slow descender, the rotating shaft 10 is installed on the bracket 6, the rotating shaft 10 is provided with a reel 8, the steel wire rope 1 is wound around the pulley 3 on the reel 8, and is installed on the bracket near the rotating shaft 10 There is a damping cylinder 7, and the piston 71 of the damping cylinder 7 is connected with the rotating shaft 10 through the slider crank mechanism 9; the piston 71 is provided with a small hole. The speed of slow descent can be adjusted by adjusting the cross-sectional area of ​​the small hole.

[0024] Such as figure 1 , figure 2 with Figure 4 Among them, the optimized solution is to use two damping cylinders, which are respectively installed on the bracket near the two ends of the rotating shaft 10, and the rotation angles of the two slider crank mechanisms connected to the pistons differ by 90°. This staggers the dead point positions of each slider-crank mechanism, reducing j...

Abstract

The invention discloses a reciprocating descent control device. A rotating shaft is arranged on a bracket and is provided with a winding drum; a steel wire rope is wound on the winding drum around a pulley; a damping cylinder is arranged on the bracket close to the rotating shaft; a piston of the damping cylinder is connected with the rotating shaft through a crank slider mechanism; and a small hole is formed on the piston. The preferable scheme of the invention is that: the reciprocating descent control device is provided with two damping cylinders, and a rotation angle of the crank slider mechanism which is connected with the damping cylinders is staggered for 90 degrees. Therefore, the dead center of the crank slider mechanism is avoided, the speed is steady during descent control, and the winding of the steel wire rope due to the speed change is avoided. The reciprocating descent control device is not controlled by a user at all during use, can realize continuous descent control, and has the advantages of steady operation, safety and reliability, and low production cost.

Description

technical field [0001] The invention relates to a high-rise escape device when a disaster occurs, in particular to a reciprocating descending device which uses a damping cylinder to delay the descending speed. Background technique [0002] With the development of society, more and more people live in high-rise buildings. Out of consideration for their own safety, people pay more and more attention to the design and development of high-rise escape devices, especially when a disaster occurs. People who don't know how to deal with danger in tall buildings are even more thought-provoking. [0003] In recent years, many enterprises and individuals at home and abroad have also carried out research and improvement on high-rise escape devices, and some have even been pushed into the market, including soft ladders, ropes, mechanically controlled and electric, and there are many types. But some escape distances of these escape devices are short and cannot be used for high-rise escape...
