[0024] Embodiment: A movable automobile maintenance lifting device comprises a base 1 on which a wheelbase guide rail 2 is provided; It should be noted that the device is fixedly installed at the target location via the base 1 and is connected to the power supply and control system; Specifically, both ends of the wheel track guide rail 2 are movably provided with a lifter, the lifter includes a wheel track driver, both ends of the wheel track driver are provided with a side support platform, and the center of the wheel track driver and on one side of the side support platform are provided with a middle support platform; It should be noted that the wheelbase drive works along the wheelbase guide rail 2 so that the distance between the lifters on both sides matches the wheelbase size of the car to be repaired, and the car to be repaired is driven onto the device so that the central support platform is located between the front and rear wheels on both sides of the car. At this time, the front and rear wheels on both sides of the car are respectively located on the side support platforms at both ends of the lifter. When the car wheels need to be repaired, the central support platform is controlled to work so that the central support platform is supported on both sides of the car chassis, so that the car is lifted to a high position, which is convenient for repairing the car wheels. When the car chassis needs to be repaired, the central support platform is controlled to rise so that the central support platform is supported on both sides of the car chassis, so that the car is lifted to a high position, and then the side support platforms on both sides are controlled to move so that the side support platforms on both sides are aligned with the front and rear wheels of the car, and then the side support platforms on both sides are controlled to rise until they are supported on the front and rear wheels of the car, and then the central support platform is lowered to expose the car chassis, which is convenient for repairing the car chassis; Compared to traditional automobile repair equipment that usually requires two sets of equipment, this technical solution only uses one set of equipment. Through the coordinated lifting and movement of the central support platform and the side support platform, it can realize the switching between wheel repair and chassis repair, saving equipment purchase costs, reducing the equipment footprint, and lowering the management cost of automobile repair equipment; Specifically, the side support platform includes a side transverse plate 3 and a wheelbase driver. An inclined plate 4 is provided at one end of the side transverse plate 3. A strip hole 5 is opened in the center of the inclined plate 4 and the side transverse plate 3. A wheel block structure is installed on the lower wall of the side transverse plate 3, and the wheel block structure movably passes through the strip hole 5. It should be noted that when the side support platform is at the lowest point, the lower end of the inclined plate 4 is in contact with the ground, and the car passes the inclined plate 4 and drives onto the side cross plate 3. When the car chassis needs to be repaired, the wheel block structure works to limit the front and rear wheels of the car, and the wheelbase drive works to make the side support platform move along the length direction of the lifter as a whole; Specifically, the middle support platform includes a middle horizontal plate 6 and a point adjuster; It should be noted that the middle horizontal plate 6 is used to support the chassis of the car, and the point adjuster works to make the middle support platform move along the length direction of the lifter as a whole; Specifically, the side transverse plate 3 and the wheelbase driver, the middle transverse plate 6 and the point adjuster are connected through a scissor frame 7; It should be noted that the side transverse plates 3, the inclined plates 4 and the middle transverse plate 6 are height-adjustable by the operation of the scissor frame 7. Specifically, limiters are provided at one end of the side horizontal plate 3 and both ends of the middle horizontal plate 6; It should be noted that the limiters are used to limit the extreme positions of the middle support platforms on both sides approaching each other, and to limit the extreme positions of the side support platforms approaching the middle support platform; Specifically, the wheelbase driver includes a slot seat 8, and the point adjuster includes a first motor 10. The first motor 10 is mounted on the inner bottom surface of the slot seat 8 through a first stabilizing frame 9. A first lead screw 11 is mounted on the driving end of the first motor 10.

The wheelbase adjustment seat 12 is movably fitted on the inner wall surface of the slot seat 8. It should be noted that the first motor 10 drives the first screw 11 to rotate, so that the point adjustment seat 15 moves laterally on the first screw 11 through the thread; Specifically, the wheelbase driver includes a second motor 13, which is mounted on the inner wall of the slot seat 8. A second lead screw 14 is mounted on the driving end of the second motor 13. The axis of the second lead screw 14 is located on one side of the axis of the first lead screw 11. A wheelbase adjustment seat 12 is movably sleeved on the second lead screw 14 through a thread. A point adjustment seat 15 is movably fitted on the inner wall of the slot seat 8. An avoidance hole 16 is opened on the wheelbase adjustment seat 12, and the first lead screw 11 movably passes through the avoidance hole 16. It should be noted that the second motor 13 drives the second screw 14 to work, so that the wheelbase adjustment seat 12 moves laterally on the second screw 14 through the thread, so that the side cross plate 3 is aligned with the vehicle wheel; When the wheels of the car need to be repaired and the wheelbase of the car is large, the central support platform can be controlled to rise first so that the central support platform supports the two sides of the car chassis and the car is lifted to a high position. Then, the wheelbase drivers on both sides are controlled to work so that the side support platforms on both sides are aligned with the front and rear wheels of the car. Then, the side support platforms on both sides are controlled to rise until they support the front and rear wheels of the car. Then, the central support platform is lowered, and the point adjuster is operated to move the point adjustment seat 15 to the central cross plate 6 to align with the four points on the car chassis close to the wheels to ensure the stability of the car support. Specifically, the limiter includes a longitudinal electric push rod 17, which is installed on the lower wall of the side horizontal plate 3. The telescopic end of the longitudinal electric push rod 17 is installed with a transverse electric push rod 18, and the telescopic end of the transverse electric push rod 18 is installed with a blocking bar 19, which is movable through the bar-shaped hole 5; It should be noted that when the chassis needs to be repaired, the longitudinal electric push rod 17 is retracted to allow the blocking bar 19 to move through the strip hole 5, and the transverse electric push rod 18 is retracted to move the blocking bar 19 in the strip hole 5 until the blocking bar 19 fits against the car wheel.
