Problems solved by technology

[0006] However, the damping structure of the elevator car in the prior art is complicated, and the focus is on the aesthetics of the elevator car interior and the comfort of riding. The ability is poor, and the car is prone to shaking or sinking when it is used, which brings harm to personal safety. Moreover, the traditional elevator car feels very obvious about the phenomenon of overweight and weightlessness, which is purely psychological for the elderly or children. panic

Embodiment 1

[0043] Such as Figure 5 Shown, a kind of damping method for elevator car, it comprises the steps:

[0044] S1. Firstly, the outer shell, inner shell and car liner in the car body are fixed by the shock-absorbing spring, the spring shock absorber and the air pressure shock absorber, which can improve the deformation resistance and shock absorption capacity of the elevator car itself. , prevent the elevator car from shaking in the running state, and improve safety;

[0045] S2. When the elevator car is accelerating upwards, the hydraulic shock absorber will extend, and the support rod will increase the inclination angle when the hydraulic shock absorber is extended, so that the fixed block slides on the top of the inner shell, and at the same time Under the action of the return spring, it will block the movement of the fixed block, effectively reducing the feeling of overweight when the elevator car accelerates upward;

[0046] S3. When the elevator car is in the upward decel...

Embodiment 2

[0057] Such as Figure 5 Shown, a kind of damping method for elevator car, it comprises the steps:

[0058] S1. Firstly, the outer shell, inner shell and car liner in the car body are fixed by the shock-absorbing spring, the spring shock absorber and the air pressure shock absorber, which can improve the deformation resistance and shock absorption capacity of the elevator car itself. , prevent the elevator car from shaking in the running state, and improve safety;

[0059] S2. When the elevator car is accelerating upwards, the hydraulic shock absorber will extend, and the support rod will increase the inclination angle when the hydraulic shock absorber is extended, so that the fixed block slides on the top of the inner shell, and at the same time Under the action of the return spring, it will block the movement of the fixed block, effectively reducing the feeling of overweight when the elevator car accelerates upward;

[0060] S3. When the elevator car is in the upward decel...

Embodiment 3

[0074] Such as Figure 5 Shown, a kind of damping method for elevator car, it comprises the steps:

[0075] S1. Firstly, the outer shell, inner shell and car liner in the car body are fixed by the shock-absorbing spring, the spring shock absorber and the air pressure shock absorber, which can improve the deformation resistance and shock absorption capacity of the elevator car itself. , prevent the elevator car from shaking in the running state, and improve safety;

[0076] S2. When the elevator car is accelerating upwards, the hydraulic shock absorber will extend, and the support rod will increase the inclination angle when the hydraulic shock absorber is extended, so that the fixed block slides on the top of the inner shell, and at the same time Under the action of the return spring, it will block the movement of the fixed block, effectively reducing the feeling of overweight when the elevator car accelerates upward;

[0077] S3. When the elevator car is in the upward decel...

Abstract

The invention discloses a damping method used for a lift car. The method comprises the steps that S1, an outer shell and an inner shell of a lift car body are fixed to pneumatic dampers through damping spring pieces between the outer shell and the inner shell, and the inner shell and a lift car liner of the lift car body are fixed to the pneumatic dampers through spring dampers between the inner shell and the lift car liner; S2, when the lift car is in an ascending acceleration state, a hydraulic damper is stretched; S3, when the lift car is in an ascending deceleration state, the hydraulic damper is contracted; S4, when the lift car is in an descending acceleration state, the lift car liner can be in a weightlessness state; and S5, when the lift car is in an descending deceleration state,the lift car liner can be in a hypergravity state, and the damping capacity and stability of the lift car liner can be improved through the functions of the spring dampers and the pneumatic dampers.Through the damping method, the damping effect is good, safety and stability are achieved, shake and noise are reduced, the feelings of hypergravity and weightlessness are reduced, and comfort of liftpassengers is improved.

Description

technical field [0001] The invention belongs to the technical field of elevator car shock absorption, and in particular relates to a shock absorption method for an elevator car. Background technique [0002] The car is a box-shaped space used by the elevator to carry and transport people and materials. The car is generally composed of main components such as the car floor, car wall, car roof, and car door. It is the car body part used by the elevator to carry passengers or goods and other loads. The ceiling is usually made of mirror stainless steel; the floor of the car is 2mm thick PVC marble pattern or 20mm thick marble mosaic. The clear height inside the car should not be less than 2m, and the clear height for the users to enter and exit the car entrance should not be less than 2m. [0003] In the use of elevators, in order to reduce or eliminate the vibration of the car, to reduce shaking and noise, reduce the feeling of overweight and weightlessness, and improve the ...
