Lift car structure

Abstract

The invention discloses a lift car structure. The lower portion of a car base is sequentially provided with a large air bag, a middle air bag and a small air bag, a car straight beam is arranged on a lift car, the top end of the car straight beam is provided with a car upper beam provided with a car jack wheel, and a steel wire rope is hinged to the car upper beam through the car jack wheel. The lift car structure has the advantages that the bottom of the lift car is provided with multiple layers of rubber air bags which are different in strength, the rubber air bags have a good effect of transitively gradual buffering from weak to strong, and therefore the lift car structure can effectively solve the problems existing in an existing lift buffering device, and is simple in structure, extremely easy to popularize and good in using effect.

Description

technical field [0001] The invention relates to an elevator car, in particular to an elevator car structure, and belongs to the technical field of elevator cars. Background technique [0002] At present, most of the elevator cars on the market are provided with car straight beams on both sides of the elevator car body, the top of the car body is provided with a car upper beam, and the middle part of the upper beam of the car is provided with a car top wheel. The motor rotates and the steel wire rope passes through the top wheel of the car to drive the elevator car to rise or fall; however, because the elevator steel wire rope is subjected to bending and deformation for a long time during work, it is prone to breakage, which will cause the elevator car to fall seriously. Accidents, at present, in order to prevent the problem of the high fall of the elevator car, springs or hydraulic cylinders are mostly installed in the pit of the elevator shaft. When the elevator falls, the ...

[0002] At present, most of the elevator cars on the market are provided with car straight beams on both sides of the elevator car body, the top of the car body is provided with a car upper beam, and the middle part of the upper beam of the car is provided with a car top wheel. The motor rotates and the steel wire rope passes through the top wheel of the car to drive the elevator car to rise or fall; however, because the elevator steel wire rope is subjected to bending and deformation for a long time during work, it is prone to breakage, which will cause the elevator car to fall seriously. Accidents, at present, in order to prevent the problem of the high fall of the elevator car, springs or hydraulic cylinders are mostly installed in the pit of the elevator shaft. When the elevator falls, the reaction force of the spring or hydraulic cylinder is used to buffer the effect. However, this This so-called buffer setting is too direct or rigid, and it has no transitional multi-level buffer setting and function, so it is easy to bring passive use to people.
