Description

Technical Field

[0001] The invention relates to the technical field of lifts, and in particular to a flexible and unhindered four-wheel positioning side sliding device under high load weight. Background Art

[0002] Car lift refers to the auto maintenance equipment used for lifting cars in the auto repair industry. Car lift plays a vital role in car repair and maintenance. It is indispensable for both major vehicle overhaul and minor repair and maintenance. The product properties and quality directly affect the personal safety of maintenance personnel. In maintenance and repair enterprises of various sizes, whether it is a comprehensive repair shop that repairs multiple models or a tire shop with a single business scope, almost all of them are equipped with lifts. There are many types of lifts, and four-wheel alignment lifts are more commonly used among them, and the side sliding device is an indispensable part of the four-wheel alignment lift.

[0003] After searching, the Chinese utility model patent with patent application number CN202120897398.9 discloses a multifunctional scissor lift for four-wheel alignment. The device is equipped with a main side skateboard and a secondary side skateboard on the scissor lift, which can not only release the stress of the tire, but also detect the side slip amount of the car tire. When using the device to align the four wheels of the vehicle, the wheels can be quickly and accurately positioned, and the operation is faster and more convenient.

[0004] Another example is a Chinese invention patent application with patent application number CN201811486980.5, which discloses a side sliding device for a four-wheel alignment lift, including a fixed column, one side of which is slidably connected to a vehicle plate, and an inclined plate is installed at one end of the vehicle plate, both ends of the vehicle plate are provided with a first slide groove, and the first slide groove is internally slidably connected to a first slider, a fixed plate is provided on the top of the first slider, and a third slide groove is provided on the top of the fixed plate. Through the cooperation of the provided clamping head and the clamping groove, and under the action of the first return spring, the two sets of side sliding mechanisms can be adjusted to adapt to most vehicles, through the cooperation of the provided third slider and the third slide groove, and under the action of the third return spring, the side sliding mechanism is fine-tuned laterally, and through the interaction of the provided second slider and the second slide groove, the purpose of longitudinal fine-tuning of the side sliding mechanism is achieved, and the combination of the two fine-tuning methods makes fine-tuning more convenient and more conducive to maintenance personnel to repair cars.
