Description

Technical Field

[0001] The utility model relates to the field of automobile maintenance, in particular to a lifting device used for automobile maintenance services. Background Art

[0002] Car maintenance is a general term for car maintenance and repair. It is to use technical means to check the faulty car, find out the cause of the fault, and take certain measures to eliminate the fault and restore it to a certain performance and safety standard. Car maintenance includes car overhaul and car minor repair. Car overhaul refers to the method of repairing or replacing any parts of the car (including basic parts) to restore the car to its good technical condition and completely (or nearly completely) restore the life of the car. Car minor repair refers to: the method of replacing or repairing individual parts to ensure or restore the working ability of the car. Car lift refers to the car maintenance equipment used for car lifting in the car maintenance industry. Lift plays a vital role in car maintenance and repair. Whether it is a major overhaul of the whole vehicle or a minor repair and maintenance, it is indispensable. Its product properties and quality directly affect the personal safety of maintenance personnel.

[0003] The jacking equipment of the prior art has the following problems: the support at the bottom of the car is mostly a horizontal lifting plate, but when the car is repaired, there is no protection on both sides of the car, which poses a great safety hazard. If the car accidentally slides, it will not only cause economic losses but also may cause safety accidents. Some lifting platforms are equipped with guardrails on both sides, but since the guardrails affect normal maintenance operations, they lack practicality.

[0004] For example, in a patent for a jacking device for automobile maintenance (Announcement No.: CN208814580U), it includes a jacking platform, two hydraulic lifting cylinders are installed at the bottom of the jacking platform, and fixing components are installed on both sides of the top of the jacking platform, and one side of the fixing component is connected to a protective component. By setting the protective component, after the car is transported to the jacking platform, the two clamping plates can be fixed on both sides of the car to be repaired on the jacking platform, thereby avoiding the phenomenon of the car shifting or even sliding during maintenance, improving the safety of the jacking equipment, and also ensuring the personal health and safety of the operator. A moving groove is set on the jacking platform, and the fixing component can slide in the moving groove through the fixing bolt at the bottom to determine the position of the protective component, so that the user can fix and select the position of the protective component on both sides of the car according to needs, avoiding blocking the parts that need to be repaired, and will not affect the maintenance work. The structure is simple and practical.

[0005] The above patent realizes a simple structure and strong practicality through the hydraulic lifting cylinder and the fixing assembly. In daily use, the operation of the hydraulic lifting cylinder will drive the lifting platform to rise and fall, and the lifting cylinder is fixed to the bottom of the platform. There is no support at the center of the platform. When the platform and the car cross contact, the structure at the center of the platform will bend due to long-term force, thereby affecting the applicable surface of the device and reducing the applicable scope of the device. Therefore, it is necessary to invent a lifting device for automobile maintenance services to solve the above problems. Utility Model Content
