At the same time, the maintenance station does not need to replace the support device according to the size of different vehicles when performing repairs and maintenance, thereby improving work efficiency and convenience.

[0023] An anti-skid rubber pad 10 is fixedly mounted on the top of the abutment plate 9 , and a limiting plate 11 is fixedly mounted on one side of the top of the abutment plate 9 .

[0024] Among them, the anti-skid rubber pad 10 is used to increase the friction between the abutment plate 9 and the vehicle chassis, preventing the vehicle from accidentally sliding or shifting during maintenance, thereby improving the safety of maintenance personnel, and at the same time avoiding scratches or damage caused by direct metal contact, and playing a certain protective role on the vehicle chassis. The limiting plate 11 is used to limit the vehicle and prevent the vehicle from shaking left and right during maintenance, further improving the safety of maintenance personnel's inspection.

[0025] Slide grooves 12 are provided at four corners of the top of the base 1 , and a plurality of reinforcing ribs 13 are fixedly mounted on the surface of the connecting plate 8 .

[0026] Among them, the slide groove 12 is used to provide moving space for the block 15, thereby ensuring that the assembly boxes 4 on both sides can move synchronously, and then adjust the gap to meet the needs of vehicles of different widths. The reinforcing ribs 13 are used to increase the overall structural strength of the abutment plate 9, so that it can better withstand the pressure and weight generated by the vehicle, thereby improving the stability and safety of the support device.

[0027] An inspection plate 14 is threadedly connected to one side of the assembly box 4 , and clamping blocks 15 are fixedly installed on both sides of the bottom of the assembly box 4 , and a polished rod 16 is movably installed inside the clamping block 15 .

[0028] Among them, Figure 2 and Figure 3 As shown, the actual number of the bare rod 16 is one, and the inspection plate 14 is used to facilitate closing the inspection port of the assembly box 4, and at the same time, it is convenient for maintenance personnel to quickly inspect the internal components of the assembly box 4. The function of limiting the assembly box 4 is realized by the block 15 and the bare rod 16, thereby ensuring that the assembly box 4 is in linear motion, and then accurately controlling the contact position between the plate 9 and the vehicle.

[0029] A plurality of positioning plates 17 are fixedly mounted on both sides of the base 1 , and threaded rods 18 are movably mounted inside the positioning plates 17 .

The self-locking universal wheel 20 realizes the rapid movement function of the device, thereby allowing the support device to be easily moved in the working area to adapt to the use requirements of different positions and angles without lifting or dragging, saving the physical strength and time of maintenance personnel.

[0033] Towing hooks 21 are fixedly mounted on both sides of the front side of the base 1 .

[0034] The towing hook 21 is conveniently connected to the vehicle by the rope, so as to achieve the purpose of quickly moving the entire device.

[0035] The working principle and use process of the utility model are as follows: when using the device, the base 1 is moved to the bottom of the vehicle through the self-locking universal wheel 20, the threaded rod 18 is driven to rotate by the control handle 19, the height of the self-locking universal wheel 20 is adjusted by the threaded rod 18, the base 1 contacts the ground, and the drive motor 2 is started. The drive motor 2 drives the assembly boxes 4 on both sides to adjust the spacing through the bidirectional threaded shaft 3. During the movement of the assembly box 4, the block 15 cooperates with the light rod 16 to ensure the linear movement of the assembly box 4. When the assembly box 4 and the load-bearing beams of the vehicle chassis of different widths mostly overlap, the drive motor 2 stops working, and four electric hydraulic telescopic rods 7 adapted to the weight of the vehicle body are selected to work, and the electric hydraulic telescopic rod 7 is used to push the abutment plate 9 to rise, and the friction between the vehicle chassis cross beam and the abutment plate 9 is increased by the anti-slip rubber pad 10. The two sides of the vehicle are limited by the limit plate 11, and the weight of the vehicle body is fully received and transmitted to the electric hydraulic telescopic rod 7 by the reinforcing rib 13. At this time, the maintenance personnel repair the bottom of the vehicle.
