Height-adjustable elevator damping device

Abstract

The height-adjustable elevator damping device comprises an elevator car, a top plate is horizontally arranged in the elevator car, a noise reduction sleeve is arranged at the upper end of a first damping pad, noise is greatly reduced, an electric telescopic rod is controlled to stretch out and draw back to drive a sliding block to move in a sliding groove, and therefore a connecting rod is driven to move; the top plate can be lifted, the surface of the car wall of the elevator car is coated with the damping coating layer, vibration energy generated by lifting and stopping of the elevator car can be absorbed, the amplitude and noise are reduced, the good damping effect is achieved, impact energy transmitted by the top plate is effectively absorbed by arranging the air bag damper, and the service life of the elevator car is prolonged. The damping device effectively improves the buffering strength and effectively eliminates low-frequency vibration, enables the elevator car to run stably, effectively improves the riding comfort of passengers, is novel in structure, adopts multiple sets of damping assemblies, and is good in damping effect and high in practicability.

Description

Technical field [0001] The present invention relates to the technical field of elevator components, in particular an adjustable height elevator shock absorption device. Background [0002] The elevator will have acceleration in operation, especially when starting and stopping, and the acceleration will affect the comfort of the elevator, especially for the situation that there are more floors and frequent start and stop. The acceleration generated by the elevator in the process of operation is vertical, the passengers in the elevator will have a feeling of overweight or weightlessness in the moment of starting and stopping, bringing many discomforts to passengers, especially the elevator with poor shock absorption performance, due to the impact of weightlessness or overweight is more obvious, some passengers will even have a sense of dizziness, there is an opposing contradiction between the traditional elevator comfort and elevator operation efficiency, therefore, how to improve ...

AI Technical Summary

Problems solved by technology

The acceleration generated by the elevator during operation is in the vertical direction. Passengers in the elevator will feel overweight or weightless at the moment of starting and stopping, which will bring a lot of discomfort to passengers, especially for elevators with poor shock absorption performance. Or the impact of overweight is more obvious, and some passengers may even feel dizzy. There is an opposite contradiction between the comfort of the traditional elevator ride and the operating efficiency of the elevator. Therefore, how to improve the shock absorption effect of the elevator and improve the comfort of passengers , is a popular research topic in the field of elevators

[0003] The currently used elevator damping device adopts a relatively simple damping device, the damping effect is weak, and it does not have the function of adjusting the height. Therefore, there is an urgent need for a height-adjustable elevator damping device to solve the above problems.
