High-rise descent control device based on hydraulic damping

Abstract

The invention discloses a high-rise descent control device based on hydraulic damping, which comprises a main shaft, a rope and an inner cam, wherein the inner cam is arranged at the main shaft, the rope is wound on the outer cylindrical surface of the inner cam, the inside of the inner cam is provided with a hydraulic cylinder, the piston rod of the hydraulic cylinder is driven by the cam wall of the inner cam to reciprocate, and the hydraulic cylinder is connected with a damping oil way which can adjust the reciprocating speed of the piston rod. The device of the invention has the advantages that the structure is simple and compact, the stability is good, the efficiency is high, the device is safe and reliable to use, the machining and assembly process is simple, the maintenance cost is low, the application range is wide, and the like.

Description

technical field [0001] The invention relates to a device for releasing heavy objects from high buildings or for people to escape from high buildings, in particular to a hydraulic damping-based slow-falling device for high buildings. Background technique [0002] At present, high-rise buildings are generally equipped with high-rise slow-down devices, which are often used to release heavy objects from high-rise buildings or to facilitate personnel to escape from high-rise buildings when a fire breaks out. The key to the design of the high-rise slow-descent device used for escape is to ensure the escape efficiency and the safety of personnel, so the electrical control device should be reduced as much as possible to improve its safety. Usually, the device is improved by cleverly using the mechanism for special design. Escape efficiency and safety. Existing slow-descent devices for high-rise buildings that are used for escape can be divided into the following categories in princ...

AI Technical Summary

Problems solved by technology

However, when the hydraulic device in the existing high-rise slow-down device used for escape works, the volume of the internal hydraulic oil changes, which will cause empty travel or jamming; the profile of the internal cam matched with the hydraulic device is a regular hexagon or an eccentric circle, When the cam rotates, the hydraulic device cannot provide damping force smoothly, which reduces the stability of the mechanism

[0006] None of the mechanisms listed above can realize the speed regulation function, and they cannot adapt to people or objects with different gravity through the adjustment device. In addition, the structures of the above-mentioned mechanisms are relatively complicated and the cost is relatively high.
