[0003] In the above technical solution, the tires are stacked on a plastic pallet, and four protective clamping rods (3) are used to fit the tire surface, so as to clamp and fix the stacked tires on the plastic pallet, thereby forming a sufficient clamping and protective structure. Since the tires are placed flat on the plastic pallet, they occupy a large lateral space, and the pallet structure is not suitable for clamping the tires in an upright state. In addition, the tires are mainly positioned longitudinally by the protective clamping rods (3) on the top, and the strength of the protective clamping rods themselves is limited, and the clamping and positioning effect is average. Finally, there are certain restrictions on the tire specifications that can be positioned, and they cannot be flexibly adjusted for tires of different specifications. Summary of the invention

DETAILED DESCRIPTION

[0027] The present invention is further described in detail below in conjunction with the accompanying drawings.

[0028] Example 1: Figure 1-Figure 3 A tire pallet shown includes a bottom frame, a positioning device 2 is arranged on the bottom frame 1, the positioning device 2 includes tire racks 11 arranged symmetrically on the left and right, a positioning space 13 for positioning the tire is formed between the two tire racks 11, the tire racks 11 are connected to the sliding positioning plate 7 arranged on the bottom frame 1, the sliding positioning plate 7 can be moved horizontally on the bottom frame 1 to adjust the position and be fixed, and a clamping device 3 is also arranged on the bottom frame to lock the front and rear ends of the tire. The bottom frame is the most basic component, responsible for connection, positioning and lifting the tire to ensure contact with other components. The two tire racks of the positioning device play the main role in positioning the tire, and the clamping device is used to lock the front and rear ends of the tire.

[0029] Specifically, the clamping device 3 includes clamping frames 12 arranged at the front and rear ends of the bottom frame 1. The clamping frames 12 can be adjusted in the front-rear direction and locked and fixed.

[0030] Specifically, the inner side of the tire rack 11 is inclined, the sliding positioning plate 7 is connected to the end face of the tire rack 11, and a plurality of positioning holes are opened at the connection between the sliding positioning plate 7 and the bottom frame 1, and the position of the tire rack 11 is fixed by fast-inserting steel pins passing through the positioning holes.

[0031] In order to reliably clamp the tire, the angle formed by the inner inclined surfaces of the two tire racks is 90 degrees, and the whole is V-shaped.

[0032] In order to effectively prevent the tire from tipping over and reliably clamp the tire, the height of the clamping frame 12 is higher than the center size of the tire.

[0033] The clamping frame 12 is provided with nylon rollers. There are three nylon rollers, including a longitudinal roller 4 and two transverse rollers 5, wherein the longitudinal roller 4 is located between the two transverse rollers 5. This structure can reduce the friction between the tire and the sharp corners of the profile of the clamping frame, and avoid damage to the tire.

[0034] In a specific technical solution, the two sides of the clamping frame 12 are respectively mounted on the guide rod 10 through the self-locking slider 8 and the non-self-locking slider 6, and the guide rod is arranged outside the tire frame. The clamping frame can move forward and backward on the guide rod to adjust the position so as to match the tire.

[0035] Specifically, the guide rod 10 is supported and fixed by the support seats 9 at both ends and in the middle, and is reliably fixed by three-point support.

[0036] When in use, after placing the tire in the positioning space between the two tire racks, after confirming the storage position of the tire in the Y-axis direction, use the quick-insert steel pin to pass through the positioning holes on the sliding positioning plate and the bottom frame beam to lock the relative position of the V-shaped sliding blocks on both sides, and restrict the movement of the stored tire in the Z-axis and -Y-axis directions. Considering the weight and size of the V-shaped tire rack, support ribs are added inside the frame and the middle part of the support ribs is cut off. The bottom is also processed by cutting off excess materials while ensuring strength and welding size, so as to ensure both strength and weight reduction.

[0037] During the sliding process, the slider needs to be limited in the X-axis movement position, and it can be locked after it is in place so that it does not move freely. Therefore, the self-locking slider needs to be quickly tightened with the stop bolt to position it. The height of the clamping frame is higher than the center size of the tire, which can effectively prevent the tire from tipping over and clamping. In order to reduce the friction between the sharp corners of the tire and the clamping frame and damage the tire, three nylon rollers in two groups are added to the clamping frame. The X-axis movement of the tire is constrained by the clamping device.

[0038] With the help of multiple devices, the movement of the tire in multiple axes is restricted, so that the tire can be firmly placed on the pallet.

[0039] Example 2: Figure 4-Figure 6 As shown, the positioning device also includes an electric push rod 15, a sliding positioning plate is connected to the side of the V-shaped tire rack, and there are two positioning holes at the connection between the sliding plate positioning plate and the bottom frame to fix the Z-axis movement of the V-shaped tire rack. The electric push rod pushes the V-shaped tire rack, and after confirming the storage position of the tire in the Y-axis direction, a quick-insert steel pin is passed through the positioning holes on the sliding positioning plate and the bottom frame beam to lock the relative positions of the V-shaped sliding blocks on both sides, which also constrains the Z-axis movement and -Y-axis movement of the stored tire.

[0040] The clamping device is composed of a double-end clamping frame and a double-sided guide assembly bolted together. The guide assembly is composed of an optical axis 17, two self-locking sliders and multiple support seats. The transmission component is composed of a left-right rotating screw 16, two screw sliders and a stepper motor 14. During use, the stepper motor drives the screw to rotate to move the slider inward and outward, and the optical axis plays a guiding role. During the sliding process, it is necessary to limit the slider's movement position in the X axis, and the stepper motor stops working after it is in place. In order to reduce the effect of the tire tipping force on the screw and the stepper motor, two self-locking sliders can be used to further lock it from moving freely. Through the combination of the positioning device and the clamping device, the X / -Y / Z axial movement of the tire is limited, so that the tire can be firmly placed on the device.

[0041] The above contents are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
