Description

Technical Field

[0001] The invention relates to the technical field of automobile maintenance, in particular to a rotatable lifting device for automobile maintenance. Background Art

[0002] Automobile maintenance refers to the technical inspection of a faulty automobile to find out the cause of the fault, take corresponding measures to eliminate the fault, and restore the performance and safety standards of the automobile. Automobile maintenance is usually divided into two types: major repairs and minor repairs. Major repairs involve repairing or replacing any parts of the automobile, including basic parts, to restore the automobile's good technical condition and lifespan; while minor repairs are to ensure or restore the working ability of the automobile by replacing or repairing individual parts. During the automobile maintenance process, in order to facilitate maintenance personnel to easily rotate the repair parts to different positions and obtain more working space in a small maintenance workshop, the present invention proposes a rotatable lifting device for automobile maintenance to help maintenance personnel perform maintenance operations more accurately, improve maintenance quality, and ensure maintenance safety.

[0003] According to the search, the Chinese patent document, announcement number: CN218320501U, discloses a rotatable lifting device for automobile maintenance, which effectively realizes the automatic lifting and rotation of the automobile engine during maintenance through the combination of a track plate, a controller, a first servo motor, a threaded rod, a slider, a circular support plate, a second servo motor, a bearing seat, a circular carrier, a roller, a third servo motor, a track groove, a screw rod, a movable block and a limit plate, and can also automatically limit and fix the automobile engine placed on the circular carrier, saving the operator's time in lifting, rotating, limiting and fixing the automobile engine, and the structure of the lifting device is relatively simple and stable, which improves the flexibility of the lifting device during use. However, in actual use, the device can only drive the components to rotate in the horizontal direction. When the bottom of the component also needs to be repaired, it cannot rotate and can only be disassembled and reinstalled, which reduces the overall work efficiency; in addition, the slider of the device is only set on one side, and the circular carrier is also installed above the support plate. There are no relevant protection or restriction measures, which is relatively unstable during operation, reducing the overall practicality. Summary of the invention
