Pneumatic spring suspension device for lift car

Abstract

The invention provides a pneumatic spring suspension device for a lift car, which comprises a car frame, a supporting beam and a drag steel rope, wherein the upper end of the car frame is connected with the supporting beam; the drag steel rope is connected with the supporting beam; the car frame comprises an outer frame of the car and an inner frame of the car; a first pneumatic spring is arranged between the upper end of the outer frame of the car and the supporting beam; a first bracket is arranged outside the upper end of a lateral plate of the inner frame of the car; a second bracket is arranged inside the upper end of a lateral plate of the outer frame of the car; a second pneumatic spring is arranged between the first bracket and the second bracket; an anti-side-stable device is arranged inside the lower end of the lateral plate of the outer frame of the car; and the anti-side-stable device is an anti-side-stable rubber pad. In the pneumatic spring suspension device for the lift car, two sets of the pneumatic spring suspension devices are adopted, the rigidity of the pneumatic spring is variable, so the devices can effectively absorb high-frequency and low-frequency vibration of the lift car, effectively reduce vibration caused by variations of lift load, ensure stable work of the car frame, improve comfort and safety thereof, and reduce energy consumption.

Description

Technical field: [0001] The invention relates to the field of machinery, in particular to elevators, in particular to a suspension device for an elevator car, in particular to a gas spring suspension device for an elevator car. Background technique: [0002] In the prior art, only a set of suspension devices consisting of springs and rubber pads are used in low-speed and medium-speed elevators. When the elevator moves up and down, the elasticity of the springs and rubber pads reduces vibration and noise. Since the stiffness of the spring and the rubber pad are constant, they are linear elastic elements, so their vibration and noise reduction effects are poor, and most of the vibration and noise will be transmitted to the passengers in the elevator car, making the passengers feel uncomfortable , At the same time, there is a relatively large frictional resistance between the elevator car and the guide rail, which results in a large energy consumption during the operation of th...
