[0040] When it is necessary to inspect the car, the vehicle is first driven to the top surface of the support 1. At this time, the inclined block 16 can be used to reduce the slope of the support 1, so as to facilitate the vehicle to drive to the top surface of the support 1. When the tire of the vehicle is on the top surface of the support 1, the double-headed motor 2 is driven to simultaneously drive the threaded rods 3 on both sides to rotate. Under the rotation of the threaded rods 3, the sliders 4 on both sides can be moved away from each other. Through the cooperation of the connecting rod 5, the top plates 6 on both sides can be driven to move up along the card slot 15, so as to The first hydraulic pump 7 and the holder 8 are pushed out to the top surface of the support 1. When the bottom surfaces of the first hydraulic pump 7 and the holder 8 are higher than the top surface of the support 1, the first hydraulic pump 7 is driven to extend out of the output end. At this time, the holders 8 on both sides can be brought close to each other, so as to limit the position of the tires of the vehicle. In addition, by arranging the double-headed motor 2, the first hydraulic pump 7, the second hydraulic pump 12, the slider 4 and the top plate 6 inside the support 1, it is possible to avoid them occupying the space on the top surface of the support 1, which is conducive to the tires of the vehicle running to the top surface of the support 1.

The guide rod 10 can guide the movement direction of the card seat 8 and improve the structural strength of the card seat 8.

[0042] Reference Figure 3 , a second hydraulic pump 12 is provided on both sides of the double-head motor 2, and the output ends of the second hydraulic pumps 12 on both sides are fixedly connected to the support frames 13, and the tops of the support frames 13 on both sides are rotatably connected to the rollers 14. By driving the second hydraulic pumps 12 on both sides to extend out of the output ends, the support frames 13 on both sides can be pushed out, and then the rollers 14 on both sides can be driven to move upward, and the bottom of the vehicle tires can be supported at this time.

[0043] Reference Figure 3-4The middle of the bottom surface of the inner wall of the support 1 is fixedly connected with a slide rail 11 on both sides, and the sliders 4 on both sides are slidably connected to the outside of the slide rails 11 on both sides.

The top of the support 1 is provided with a clamping groove 15 on both sides, and the top plates 6 on both sides are respectively located inside the clamping grooves 15 on both sides. The movement direction of the slider 4 can be guided by the slide rail 11. The clamping groove 15 can limit the top plate 6, and then guide it to move upward.

[0044] Reference Figure 1 Figure 2 The front and rear sides of the outer wall of the support 1 are fixedly connected with reinforcement blocks 17, the middle sides of the two reinforcement blocks 17 are fixedly connected with telescopic rods 18, the output ends of the two telescopic rods 18 are fixedly connected with transverse plates 19, and the adjacent sides of the two transverse plates 19 are fixedly connected with side plates 20. The adjacent sides of the two reinforcement blocks 17 are provided with grooves 21, and the side plates 20 are respectively located inside the grooves 21 on both sides. The structural strength of the support 1 can be improved by the reinforcement blocks 17, and the side plates 20 can be pushed out to the two sides of the vehicle tire by driving the telescopic rod 18 to extend out of the output end, and the outer side of the vehicle tire can be limited at this time.

[0045] Working principle: When the vehicle needs to be inspected, the vehicle tires are aligned with the support 1, and then the vehicle is driven so that the vehicle tires pass through the inclined plane block 16 and enter the top surface of the support 1. At this time, the inclined plane block 16 can reduce the slope of the support 1, which is conducive to the vehicle driving to the top surface of the support 1;

[0046] When the tire of the vehicle is on the top surface of the support 1, the double-headed motor 2 is driven to simultaneously drive the threaded rods 3 on both sides to rotate. Under the rotation of the threaded rods 3, the sliders 4 on both sides can be moved away from each other. Through the cooperation of the connecting rod 5, the top plates 6 on both sides can be driven to move up along the card slot 15, so as to push the first hydraulic pump 7 and the card seat 8 to the top surface of the support 1;

[0047] When the bottom surfaces of the first hydraulic pump 7 and the base 8 are both higher than the top surface of the support 1, the first hydraulic pump 7 is driven to extend out of the output end. At this time, the bases 8 on both sides can be brought close to each other, so that the tires of the vehicle can be limited, and the tires of the vehicle are placed in the middle of the top surface of the support 1. At this time, the second hydraulic pumps 12 on both sides are driven to extend out of the output ends to push out the support frames 13 on both sides. When the rollers 14 contact the bottom surfaces of the vehicle tires, the vehicle can be lifted up. By arranging the double-headed motor 2, the first hydraulic pump 7, the second hydraulic pump 12, the slider 4 and the top plate 6 inside the support 1, it is possible to avoid them occupying the space on the top surface of the support 1, which is conducive to the tires of the vehicle running to the top surface of the support 1.

[0048] Then, by driving the telescopic rods 18 on both sides to extend out of the output end, the telescopic rods 18 can be used to lift up the transverse plates 19 on both sides, so that the transverse plates 19 can drive the side plates 20 to slide upward inside the groove 21, and the outer side of the vehicle tire can be limited at this time.

[0049] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein.
