Description

Technical Field

[0001] This utility model relates to the field of transfer device technology, and in particular to an electric vehicle tire transfer device to prevent rolling off. Background Technology

[0002] Currently, electric vehicle tires typically require specialized transfer devices for handling during maintenance, storage, and transportation. Existing electric vehicle tire transfer devices mainly consist of a carrying platform, rollers, and a simple fixing structure. Common structures include flatbed trolleys secured with rubber straps, or U-shaped brackets with manual clamping devices. When using these devices, operators lay the tire flat or stand it upright on the carrying platform, secure it with straps or clamping devices, and then push the device to transfer it.

[0003] Currently, most electric vehicle tire transfer devices on the market use traditional strapping for fixation. This method has many shortcomings in practical use. First, each loading and unloading requires repeated tightening and loosening operations, which is time-consuming and labor-intensive, seriously affecting work efficiency. Second, the common U-shaped bracket structure is relatively simple in design, and its clamping range is strictly limited. It often fails to provide effective fixation for tires of different sizes, especially large-diameter off-road tires. More seriously, existing devices have obvious defects in anti-rollover design. When encountering bumpy roads during transportation, the tire is very likely to shift or even fall off completely, which not only poses a safety hazard but also often causes the tire edge to rub against the fixing structure, resulting in tire surface damage.

[0004] Therefore, given the lack of an effective anti-roll-off structure in the existing devices, the tires are prone to displacement or even falling off when encountering bumps during transportation, posing a safety hazard and easily causing wear on the tire edges. A roll-off-proof electric vehicle tire transfer device can be designed, employing a three-dimensional fixing scheme, which can ensure that the tires remain completely still even under the most bumpy transportation conditions, thus completely eliminating the risk of rolling or falling off. Utility Model Content

[0005] In order to overcome the lack of an effective anti-roll-off structure in existing devices, the outer tire is prone to displacement or even falling off when encountering bumps during transportation, which poses a safety hazard and easily causes wear on the edge of the outer tire.

[0006] The technical solution of this utility model is as follows: an anti-rollover electric vehicle tire transfer device, including a vehicle platform, with pulleys installed at the four corners of the lower end of the vehicle platform, a push handle installed at the upper end of the vehicle platform, and positioning plates. Two sets of positioning plates are provided, arranged in an inverted octagon shape and rotatably connected to the upper end of the vehicle platform. A vertical fixing seat is fixedly connected to the middle of the rear end of the vehicle platform. The vertical fixing seat is located at the symmetrical center between the two sets of positioning plates. A through groove is opened on the upper part of the vertical fixing seat. A vertically arranged first threaded post is fixedly connected in the through groove. An adjusting nut is threadedly connected to the first threaded post. A bearing is fitted around the outer circumference of the adjusting nut. A horizontally arranged support plate is fixedly connected to the outer ring of the bearing. The support plate and the vertical fixing seat are perpendicular to each other. An upper limit plate is rotatably connected to the front end of the support plate through a rotating shaft.

[0007] Preferably, the operator controls the direction and speed of the transfer device by pushing the push rod installed on the upper part of the vehicle board and cooperating with the pulley. By rotating the adjusting nut on the outer periphery of the first threaded column in the vertical fixing seat, the bearing and support plate are driven to slide up and down to accommodate tires of different diameters. Two sets of positioning plates arranged in an inverted V-shape can rotate to clamp the electric vehicle tire and prevent it from rolling or slipping. The electric vehicle tire is fitted on the support plate, and the lower surface of the electric vehicle tire is in contact with the positioning plate. By rotating the shaft and the upper limit plate, it is flipped outward to restrict the tire from moving upward and prevent the tire from coming off during transportation.

[0008] Preferably, a mounting base is fixedly connected to the lower end of the support plate, a slotted bracket is fixedly connected to the outer surface of the rotating shaft, the rotating shaft passes through the slotted bracket, a slidable insert rod is horizontally inserted into the mounting base, a toothed bracket that meshes with the slotted bracket is fixedly connected to the front end of the insert rod, a stop is fixedly connected to the rear end of the insert rod, and a spring is fixedly connected between the mounting base and the toothed bracket.

[0009] Preferably, a U-shaped frame is fixedly connected to the upper left and right sides of the vehicle board and the lower end of the positioning plate. A rotatable ring is fitted around the outer periphery of the U-shaped frame, and a telescopic cylinder is installed at an angle between two corresponding rings on the same side.

[0010] Preferably, the front and rear ends of the vehicle body are fixedly connected with side plates that are symmetrically distributed on the left and right. The side plates are arranged in groups of two and correspond to the positioning plate. The side plates and the positioning plate are provided with pins that are fixedly connected to the positioning plate.

[0011] Preferably, the upper surface of the positioning plate is evenly distributed with elastic protrusions, and the inner walls on both sides of the through groove of the vertical fixing seat are provided with guide grooves. Guide sliders that slide longitudinally are provided in the guide grooves, and the guide sliders are fixedly connected to the bearings.

[0012] Preferably, a sliding lifting column is inserted into the support plate, an anti-detachment baffle is fixedly connected to the upper end of the lifting column, a second threaded column is fixedly connected to the lower front end of the anti-detachment baffle, a rotatable lower limit plate is sleeved on the second threaded column, and a locking nut for locking the lower limit plate is threaded to the outer circumference of the second threaded column.

[0013] The beneficial effects of this utility model are as follows: It adopts an inverted V-shaped adjustable positioning plate structure. This structure, through a precise mechanical linkage device, can automatically adjust the opening and closing angle according to the actual size of the tire, achieving a perfect clamping effect for tires of various specifications. The ingenious cooperation between the support plate and the adjustable upper limit plate forms a comprehensive constraint system. Combined with the lateral fixing function of the positioning plate, a complete three-dimensional fixing space is constructed. This three-dimensional fixing scheme ensures that the tire remains perfectly still even under the most bumpy transportation conditions, completely eliminating the risk of rolling or falling off. Furthermore, because the tire remains stable throughout the entire transportation process without any displacement, it fundamentally avoids the tire wear problems easily caused by traditional devices, providing a reliable guarantee for the intact transportation of tires.

[0019] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0020] Example 1

[0021] Please see Figure 1 and Figure 2 This utility model provides an embodiment: an anti-rollover electric vehicle tire transfer device, including a vehicle platform 1, with pulleys 2 installed at the four corners of the lower end of the vehicle platform 1. There are four pulleys 2, two of which are omnidirectional wheels and the other two are directional wheels. A push handle 3 is installed at the upper end of the vehicle platform 1. It also includes positioning plates 4, with two sets of positioning plates 4 arranged in an inverted octagonal shape and rotatably connected to the upper end of the vehicle platform 1. A vertical fixing seat 5 is fixedly connected to the center of the rear end of the vehicle platform 1, and the vertical fixing seat 5 is located at the symmetrical center between the two sets of positioning plates 4. The vertical fixing base 5 has a through groove on its upper part, and a vertically arranged first threaded post 6 is fixedly connected in the through groove. An adjusting nut 7 is threaded onto the first threaded post 6. A bearing 8 is fitted around the outer circumference of the adjusting nut 7. A horizontally arranged support plate 9 is fixedly connected to the outer ring of the bearing 8. The support plate 9 is perpendicular to the vertical fixing base 5. An upper limit plate 11 is rotatably connected to the front end of the support plate 9 through a rotating shaft 10. A mounting base 12 is fixedly connected to the lower end of the support plate 9. A grooved retainer 13 is fixedly connected to the outer surface of the rotating shaft 10. A rotating shaft 10 passes through a slotted bracket 13. A slidable insert rod 14 is horizontally inserted into the mounting base 12. A toothed bracket 15 that meshes with the slotted bracket 13 is fixedly connected to the front end of the insert rod 14. A stop block 16 is fixedly connected to the rear end of the insert rod 14. A spring 17 is fixedly connected between the mounting base 12 and the toothed bracket 15. U-shaped frames 18 are fixedly connected to the upper left and right sides of the car plate 1 and the lower end of the positioning plate 4. Rotatable rings 19 are fitted around the outer periphery of the U-shaped frames 18. Two corresponding rings 19 on the same side are tilted together. Equipped with a telescopic cylinder 20, the front and rear ends of the vehicle plate 1 are fixedly connected with symmetrically distributed side plates 21. Each pair of side plates 21 corresponds to the positioning plate 4. A pin 22 is installed through the side plates 21 and the positioning plate 4. The pin 22 is fixedly connected to the positioning plate 4. Elastic protrusions 23 are evenly distributed on the upper surface of the positioning plate 4. Guide grooves 24 are opened on both sides of the through groove of the vertical fixing seat 5. A guide slider 25 that slides longitudinally is installed in the guide groove 24. The guide slider 25 is fixedly connected to the bearing 8.

[0022] In use, the operator pushes the push lever 3, moving the vehicle plate 1 to the side of the electric vehicle tire to be transported via the pulley 2. Rotating the adjusting nut 7 causes the bearing 8 to move the support plate 9 up and down along the first threaded post 6 to the appropriate height. The guide slider 25 slides within the guide groove 24, ensuring the support plate 9 rises and falls smoothly. The telescopic cylinder 20 is activated, pushing the ring 19 to move the U-shaped frame 18, causing the two sets of positioning plates 4 to rotate around the pin 22, unfolding or retracting in an inverted V-shape to accommodate the tire width. The elastic protrusions 2 on the inner surface of the positioning plate 4... 3. Contact with the outer tire increases friction and prevents slippage.

The spring 17 is compressed. The toothed bracket 15 separates from the grooved bracket 13. Rotate the upper limit plate 11 through the rotating shaft 10 so that the upper limit plate 11 covers the surface of the outer tire. Release the spring 17. The toothed bracket 15 moves forward and engages with the grooved bracket 13. Lock the angle of the upper limit plate 11 to prevent it from rebounding. Push the push rod 3. The vehicle plate 1 moves through the pulley 2 to complete the transfer.

[0023] Example 2

[0024] Please see Figures 2-4 This utility model provides an embodiment: an anti-rollover electric vehicle tire transfer device, which differs from embodiment 1 in that a lifting column 26 that can slide up and down is inserted into the support plate 9, an anti-detachment baffle 27 is fixedly connected to the upper end of the lifting column 26, a second threaded column 28 is fixedly connected to the lower front end of the anti-detachment baffle 27, a rotatable lower limit plate 29 is sleeved on the second threaded column 28, and a locking nut 30 for locking the lower limit plate 29 is threadedly connected to the outer circumference of the second threaded column 28.

[0025] The lifting column 26 and the lower limit plate 29 are used to limit the lower part of the electric vehicle tire, which is suitable for transporting tires that are higher or more prone to shaking. The rest of the structure is the same as in Example 1.

[0026] Through the above steps, an inverted V-shaped adjustable positioning plate 4 structure is adopted. This structure, through a precise mechanical linkage device, can automatically adjust the opening and closing angle according to the actual size of the tire, achieving a perfect clamping effect for tires of various specifications. The ingenious cooperation between the support plate 9 and the adjustable upper limit plate 11 forms a comprehensive constraint system. Combined with the lateral fixing function of the positioning plate 4, a complete three-dimensional fixing space is constructed. This three-dimensional fixing scheme can ensure that the tire remains motionless even under the most bumpy transportation conditions, completely eliminating the risk of rolling or falling off. At the same time, since the tire remains stable throughout the transportation process without any displacement, it fundamentally avoids the tire wear problem that is easily caused by traditional devices, providing a reliable guarantee for the intact transportation of tires. This solves the problem that existing devices lack an effective anti-roll-off structure, which makes the tire prone to displacement or even falling off when encountering bumps during transportation, posing a safety hazard and easily causing wear on the tire edges.
