[0038] Stabilization component 10 is mounted on the end of the movable base 1 away from the support frame 2. Stabilization component 10 is used to restrict the movement of the movable base 1.

[0039] In this embodiment, loading frames are fixedly connected to the four corners of the mobile base 1, and travel wheels are rotatably connected to the loading frames;

[0040] In this embodiment, a battery box is fixedly connected to the middle of the top of the mobile base 1. The battery box contains a storage battery, which is electrically connected to the drive motor 4. By mounting the storage battery in the battery box, the storage battery can be effectively protected to prevent damage. In addition, the storage battery can provide the required power to the drive motor 4, making the drive motor 4 more convenient to use.

[0041] In this embodiment, an arc plate is fixedly connected to one end of the fixed clamping plate 6 and the movable clamping plate 8, and anti-slip texture is provided on the arc plate. By setting the sliding plate, it can make a larger range of contact with the edges of both ends of the tire, so as to ensure the positioning effect of the fixed clamping plate 6 and the movable clamping plate 8.

[0042] Adjustment component 9 includes:

[0043] Positioning seat 11 is fixedly connected to the side of fixed clamping plate 6 near moving clamping plate 8. One end of positioning seat 11 is rotatably connected to transmission plate 12. The end of transmission plate 12 away from positioning seat 11 is rotatably connected to push plate 13.

[0046] Example 2:

[0047] Please see Figure 1-5 This embodiment provides a technical solution based on Embodiment 1: the stabilization component 10 includes:

[0048] Mounting plate 18 is fixedly connected to the end of the movable base 1 away from the support frame 2. Both ends of one side of mounting plate 18 are fixedly connected to assembly frame 19. A rotating shaft 20 is rotatably connected between the two assembly frames 19. A force-bearing frame 21 is fixedly connected to the top of the rotating shaft 20 at an incline. Both ends of the force-bearing frame 21 are provided with linkage through grooves 22.

[0049] Guide plate 23 is inclined and fixedly connected to the bottom end of linkage channel 22, and a stabilizing plate 24 is fixedly connected to the end of guide plate 23 away from the rotating shaft 20;

[0050] Two guide slide rods 25 are slidably connected to the two ends of the top of the mounting plate 18. One end of the guide slide rod 25 is fixedly connected to a limiting piece 26. A helical spring 27 is fixedly connected between the limiting piece 26 and the mounting plate 18. The end of the guide slide rod 25 away from the limiting piece 26 is fixedly connected to a mounting ear 28, and one end of the mounting ear 28 is also movably connected to the inside of the corresponding linkage slot 22.

[0051] In this embodiment, one end of the mounting ear 28 is fixedly connected to a linkage pin, and the mounting ear 28 is movably connected to the inside of the linkage slot 22 through the linkage pin. Since the linkage pin is connected inside the linkage slot 22, when the force frame 21 rotates, it can press the linkage pin, causing the linkage pin to drive the guide slide rod 25 to move linearly.

[0052] In this embodiment, the bottom end of the stabilizing plate 24 is fixedly connected with multiple stabilizing protrusions to increase the friction with the ground.

[0053] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0054] Working principle: First, place the tire of the transport vehicle between the fixed clamping plate 6 and the movable clamping plate 8, and make the tire contact the fixed clamping plate 6. Then, rotate the adjusting screw 16. With the connection between the adjusting screw 16 and the positioning plate 15, the adjusting screw 16 can drive the push ear 17 to move linearly. With the connection between the push ear 17 and the push through groove 14, when the push ear 17 moves linearly, it can drive the transmission plate 12 to rotate under the support of the positioning seat 11. Since the push plate 13 is connected between the transmission plate 12 and the movable clamping plate 8, when the transmission plate 12 rotates, it can pull the movable clamping plate 8 to move linearly under the limit of the limit slide rod 7 through the push plate 13 until the movable clamping plate 8 contacts the tire, and the tire is positioned between the movable clamping plate 8 and the fixed clamping plate 6.

[0055] The drive motor 4 is started to drive the drive screw 3 to rotate. With the drive screw 3 connected to the push seat 5, the push seat 5 can drive the tire to move vertically until the height of the tire is adapted to the wheel assembly height of the transport vehicle.

[0056] Pushing the support frame 21 causes the rotating shaft 20 to rotate. With the rotating shaft 20 connected to the guide plate 23, the guide plate 23 can cause the stabilizing plate 24 to flip away from the ground. When the support frame 21 rotates, it can push the guide slide rod 25 to move by means of the mounting ear 28, and stretch the coil spring 27 by means of the limiting plate 26. When the mounting ear 28 contacts the mounting plate 18, pushing the support frame 21 again will cause the moving base 1 to move forward because the support frame 21 is blocked. After the tire is pushed to the predetermined assembly position, the support frame 21 is released, and the coil spring 27 can be used to push the support frame 21 away from the mounting plate 18, so that the stabilizing plate 24 contacts the ground and the moving base 1 stops. Then, the personnel can use tools to install the tire and the transport vehicle.
