[0030] like Figures 1-8 As shown, a load-bearing wheel structure includes: a support leg 2, a side plate 3 and a baffle 4,

[0031] The legs 2 are provided with two groups, and the two groups of legs 2 are respectively arranged in parallel. The two groups of legs 2 are installed at the bottom of the forklift of the prior art. The two groups of legs 2 are fixedly connected in parallel at both ends of the forklift. The triangle formed by the center points of the two groups of legs 2 and the forklift can stably provide support for the forklift, thereby preventing the forklift from overturning when the forklift moves by the legs 2. Among them, the larger the distance between the fixed legs 2 on both sides of the forklift, the more stable the support provided by the legs 2 and the driving wheels 21 for the forklift. When the width of the legs 2 is reduced, the distance between the two groups of legs 2 becomes larger, which just provides stability for the forklift.

[0032] The side panels 3 are fixedly connected to the legs 2, and a central axis 5 is provided inside the side panels 3. The upper and lower ends of the central axis 5 are respectively fixedly connected to connecting plates 8. The two ends of the connecting plates 8 are respectively fixedly connected to the inner walls of the side panels 3. The baffle 4 is connected to the central axis 5. The inner wall of the baffle 4 is connected to two sets of load-bearing wheels 9. The two sets of load-bearing wheels 9 are respectively located on both sides of the central axis 5. The load-bearing wheels 9 roll along the ground. The supporting movement provided by the load-bearing wheels 9 is transmitted to the side panels 3 through the baffle 4, and then transmitted to the forklift through the legs 2. When the forklift travels on a bumpy ground, a set of load-bearing wheels 9 rolls into the pit. , the other set of load-bearing wheels 9 is still on the ground, and the two sets of load-bearing wheels 9 are connected together by the baffle 4. When the load-bearing wheels 9 want to move out of the pit, the two sets of load-bearing wheels 9 rotate around the central axis 5 through the baffle 4. At this time, the load-bearing wheels 9 in the pit roll along the pit, so that the load-bearing wheels 9 are separated from the pit, further ensuring that the forklift can move stably on the bumpy ground and avoid the forklift from bumping. The connecting plate 8 and the side plate 3 are fixedly connected to form a box structure, which further improves the rigidity of the side plate 3. At the same time, the connecting plate 8 provides bending strength for the central axis 5.

[0033] In some specific embodiments, mounting grooves 6 are respectively provided at both ends of the side panels 3, and there are two groups of side panels 3. The inner walls of the two groups of side panels 3 are fixedly connected to the front panels 7, the inner walls of the mounting grooves 6 do not contact the baffle 4, and the front panels 7 and the side panels 3 form an I-shape, connecting the two groups of side panels 3 together. When the load-bearing wheels 9 are installed, the two groups of load-bearing wheels 9 are first placed in the side panels 3 respectively, and the two groups of load-bearing wheels 9 are located on both sides of the connecting plate 8. The baffle 4 is installed on the side panel 3 through the mounting grooves 6, wherein a gap is left between the mounting grooves 6 and the baffle 4 to ensure that the baffle 4 can rotate around the axis of the central axis 5, thereby achieving the effect of the baffle 4 floating with the load-bearing wheels 9.

[0034] In some specific embodiments, two groups of baffles 4 are provided and are located at both ends of the load-bearing wheel 9 respectively. A floating hole 12 is opened through the center of the baffle 4, and an axial hole 20 is opened at both ends of the baffle 4 respectively. The inner wall of the floating hole 12 is cooperated with the central axis 5, and the axial hole 20 is cooperated with the wheel axle 10. The wheel axle 10 is cooperated with the load-bearing wheel 9. The floating hole 12 opened on the baffle 4 is installed on the central axis 5, and the axis center line of the load-bearing wheel 9 is aligned with the axis center line of the axial hole 20. Then, the wheel axle 10 is passed through the axial hole 20 and the interior of the load-bearing wheel 9 in turn. The wheel axle 10 is installed inside the load-bearing wheel 9, and the wheel axle 10 provides support for the load-bearing wheel 9.

[0035] In some specific embodiments, a sliding bearing 18 is fixedly connected to the inner wall of the floating hole 12, and a spacer sleeve 19 is fixedly connected to the outer wall of the sliding bearing 18. The inner wall of the spacer sleeve 19 is abutted against the central axis 5. When the baffle 4 is installed on the central axis 5, the spacer sleeve 19 is sleeved on the central axis 5, and the inner wall of the spacer sleeve 19 is abutted against the central axis 5. When the baffle 4 rotates around the central axis 5, the baffle 4 drives the sliding bearing 18 to rotate around the axis center line of the central axis 5 through the spacer sleeve 19. The sliding bearing 18 provides the spacer sleeve 19 and the baffle 4 with self-rotation around the axis center line of the central axis 5, thereby reducing the friction between the baffle 4 and the central axis 5.

[0036] In some specific embodiments, the two ends of the outer wall of the axle 10 are respectively fixedly connected with a connecting seat 13, and the two ends of the axle 10 are respectively matched with a locking assembly. An oil cup 11 is opened inside the axle 10 in a direction perpendicular to the baffle 4, and a number of balls 14 are provided between the connecting seat 13 and the load-bearing wheel 9. The balls 14 are respectively matched with the connecting seat 13 and the load-bearing wheel 9, and the oil cup 11 is respectively matched with the inner wall of the load-bearing wheel 9 and the balls 14. The locking assembly includes: a locking assembly includes: a limit plate 15 and a screw 16. The side ends of the axle 10 are respectively provided with a limit groove 17, and the inner wall of the limit groove 17 is connected to the limit plate 15. The limit plate 15 is fitted with the baffle 4.

At the same time, the limit plate 15 and The baffle 4 is fitted, and then the screw 16 is threadedly connected to the limit plate 15 and the baffle 4. The screw 16 fixes the limit plate 15 to achieve the effect of fixing the wheel axle 10. The limit plate 15 and the inner wall of the limit groove 17 abut to ensure that the wheel axle 10 will not rotate with the load-bearing wheel 9. At the same time, both ends of the wheel axle 10 are limited. When the load-bearing wheel 9 rolls, the load-bearing wheel 9 rolls along the inner wall of the connecting seat 13 through the ball bearing 14, reducing the friction load of the load-bearing wheel 9 rolling directly through the wheel axle 10. When the load-bearing wheel 9 rolls for a long time, lubricating oil can be passed between the wheel axle 10 and the load-bearing wheel 9 through the oil cup 11. The lubricating oil provides lubrication to the inner wall of the load-bearing wheel 9 and the ball bearing 14 respectively, ensuring the service life of the ball bearing 14 of the load-bearing wheel 9. When the load-bearing wheel 9 is worn, the staff can replace the load-bearing wheel 9 by removing the locking assembly.
