Lifter with double-layer lifting function and working method thereof

Abstract

The invention discloses a lifter with a double-layer lifting function. The lifter comprises a hydraulic system, a set of bases, a set of first shear-type supporting arms, a set of second shear-type supporting arms, a set of lifting platforms, a set of trays, a set of first crossbeams, a set of second crossbeams, a set of adjustable connecting plates and a control module. The lower portions of the first shear-type supporting arms are connected with the bases, the upper portions of the first shear-type supporting arms are connected with the lifting platforms, and the middles of the first shear-type supporting arms are connected with the first crossbeams. The lower portions of the second shear-type supporting arms are connected with the lifting platforms, the upper portions of the second shear-type supporting arms are connected with the trays, and the middles of the second shear-type supporting arms are connected with the second crossbeams. The adjustable connecting plates are connected with the bases so that the upper layer and lower layer lifting function can be selectively achieved according to the conditions of overhaul vehicles. The hydraulic system is divided into two small parts of the upper part and the lower part to control actuating elements correspondingly, and all parts of the hydraulic system are mounted on the bases and the lifting platforms, so that an electric control cabinet does not need to be arranged independently, the space requirement is low, the distance can be adjusted for the vehicles of different models, the range of adaptable vehicle models is wide, and operation is easy and convenient.

Description

technical field [0001] The invention relates to the technical field of automobile lifts, in particular to a lift with a double-layer lifting function. Background technique [0002] The car lift is a device used for lifting the car in the process of car maintenance. When the car is driven to the lift station, the car can be lifted to a certain height through manual operation, which is convenient for car maintenance. Lifts play a very important role in car repair and maintenance. Now repair shops are equipped with lifts. Lifts are essential equipment for car repair or maintenance. [0003] At present, the function of the lift is not powerful enough. Generally, it only has a single-layer lifting function. If it is supported by car tires, it is impossible to repair the tires. If it uses a hydraulic system, the length of the hydraulic rod is long and requires high space. Adjusting the spacing for different models of cars has a small scope of application, and most lifts need to b...

[0003] At present, the function of the lift is not powerful enough. Generally, it only has a single-layer lifting function. If it is supported by car tires, it is impossible to repair the tires. If it uses a hydraulic system, the length of the hydraulic rod is long and requires high space. Adjust the spacing for different models of cars, the scope of application is small, and most lifts need to be equipped with a separate electric control cabinet, which takes up more space and is difficult to operate
