[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0022] Reference Figures 1-3 This utility model provides a car wheel lifting tooling, including a bracket 1, a lifting component is provided on the bracket 1, and a clamping mechanism is connected to the movable end of the lifting component;

[0023] The clamping mechanism includes a support plate 2 connected to the movable end of the lifting assembly. A first gripping arm 3 and a second gripping arm 4 are provided on the support plate 2. The first gripping arm 3 and the second gripping arm 4 are rotatably connected by a first rotating shaft 5, which is located between the two ends of the first gripping arm 3 and the second gripping arm 4. A gripping hook 6 is fixedly connected to one end of the first gripping arm 3 and the second gripping arm 4. The end of the first gripping arm 3 away from the gripping hook 6 is fixedly connected to the support plate 2. The end of the second gripping arm 4 away from the gripping hook 6 is connected to an opening and closing assembly. The opening and closing assembly drives the second gripping arm 4 to rotate around the first rotating shaft 5, thereby changing the opening degree of the first gripping arm 3 and the second gripping arm 4. When the first gripping arm 3 and the second gripping arm 4 are in a scissor-like state, the two gripping hooks 6 are set opposite to each other.

[0024] Specifically, a connecting block is fixedly connected to the first gripping arm 3. The connecting block is fixedly connected to the first rotating shaft 5. The first rotating shaft 5 is rotatably connected to the second gripping arm 4. The first rotating shaft 5 is located between the two ends of the first gripping arm 3 and the second gripping arm 4, thereby forming a scissor structure.

[0025] When the clamping mechanism clamps the wheel, the opening and closing assembly drives the second gripping arm 4 to rotate around the first rotating shaft 5, reducing the opening and closing angle of the first gripping arm 3 and the second gripping arm 4, allowing the two gripping hooks 6 to pass through the center hole of the wheel. Then, the opening and closing assembly increases the opening and closing angle of the first gripping arm 3 and the second gripping arm 4, making the overall width of the two gripping hooks 6 greater than the inner diameter of the center hole of the wheel, preventing the two gripping hooks 6 from detaching from the center hole of the wheel. When the wheel is lifted by the lifting assembly, the two gripping hooks 6 abut against the end face of the center hole of the wheel to prevent the wheel from falling. This utility model uses the positioning method of the center hole of the wheel to achieve wheel gripping, which is simple and convenient to operate, improves work efficiency, and achieves convenient, efficient and safe hoisting.

[0026] Furthermore, a rubber layer is wrapped around the first gripper arm 3, the second gripper arm 4, and the gripper hook 6 to increase friction while achieving flexible contact with the wheel, thus reducing damage to the wheel.

[0027] In some alternative embodiments, the opening and closing assembly includes a pull rope 7 connected to the second gripping arm 4, located at the end of the second gripping arm 4 away from the gripping hook 6.

In its natural state, the first gripping arm 3 and the second gripping arm 4 are in a scissor-like state. Furthermore, in its natural state, the overall width of the two gripping hooks 6 is greater than the inner diameter of the wheel's center hole.

[0028] In some alternative embodiments, a handle 10 is rotatably connected to the support plate 2 via a second rotating shaft 9. The second rotating shaft 9 is parallel to the first rotating shaft 5. The end of the pull rope 7 away from the second gripping arm 4 is connected to the side wall of the handle 10. The pull rope 7 is located between the first rotating shaft 5 and the second rotating shaft 9. The pull rope 7 is located on the side of the second gripping arm 4 away from the spring 8.

[0029] The top of the handle 10 is rotatably connected to a second rotating shaft 9, which is fixedly connected to the support plate 2. The two ends of the pull rope 7 are fixedly connected to the side wall of the handle 10 and the side wall of the second grab arm 4, respectively.

[0030] In some alternative embodiments, a support handle 11 is fixed to the support plate 2, and the support handle 11 is located on the side of the handle 10 away from the second gripping arm 4.

[0031] In use, press your thumb on the support handle 11 and hold the handle 10 with the remaining fingers. Apply force to rotate the handle 10 toward the support handle 11, causing the spring 8 to extend. The pull rope 7 pulls the end of the second gripping arm 4 toward the end of the first gripping arm 3, reducing the opening angle between the second gripping arm 4 and the first gripping arm 3. At this time, the overall width of the two gripping hooks 6 is less than the inner diameter of the wheel's center hole. Pass the gripping hooks 6 through the wheel's center hole and slowly release the handle 10. The spring 8 shortens and returns to its original position, increasing the opening angle between the second gripping arm 4 and the first gripping arm 3. At this time, the overall width of the two gripping hooks 6 is greater than the inner diameter of the wheel's center hole, preventing the gripping hooks 6 from falling off and achieving the gripping of the wheel.

[0032] In some alternative embodiments, the lifting assembly includes an electric hoist 12, which is mounted on a support 1, and the hook on the wire rope of the electric hoist 12 is connected to the support plate 2.

[0033] Electric hoists are mainly composed of an electric motor, a transmission mechanism, and a drum or sprocket. They are a type of lifting equipment with features such as small size, light weight, simple operation, and convenient use. They are used in industrial and mining enterprises, warehouses, docks, and other places that require lifting and moving (specific details are existing technologies and will not be elaborated here).

[0034] In some alternative embodiments, a lifting ring 13 is fixedly connected to the support plate 2. The lifting ring 13 is located on one side of the support plate 2, and the first grab arm 3, the second grab arm 4, the support handle 11 and the handle 10 are all located on the other side of the support plate 2. The lifting ring 13 is located at the end of the support plate 2 near the spring 8, and the lifting ring 13 is hooked on the hook of the wire rope of the electric hoist 12.

[0035] In some alternative embodiments, the bracket 1 is an inverted frame with the opening facing downwards. A first linear drive is fixedly connected to the bracket 1, and a longitudinal beam 15 is fixedly connected to the moving end of the first linear drive. An electric hoist 12 is installed on the longitudinal beam 15.

[0036] In some alternative embodiments, the middle part of the longitudinal beam 15 is fixedly connected to the first linear drive member, and the bottom of the longitudinal beam 15 is fixedly connected to the second linear drive member, which is perpendicular to the first linear drive member. The electric hoist 12 is fixedly connected to the moving end of the second linear drive member.

[0037] Specifically, the bracket 1 is a square steel structure, and the bottom is fixed to the base with bolts. The first linear drive and the second linear drive can be linear motor structure, lead screw motor structure, etc. This embodiment does not impose any restrictions, as long as it can achieve linear forward and backward movement. In use, after the wheel is lifted, the first linear drive and the second linear drive realize the displacement of the wheel in the horizontal direction, and the electric hoist 12 realizes the displacement of the wheel in the vertical direction, thereby realizing the transfer of the wheel.

[0038] In use, the lifting ring 13 is hooked onto the hook of the electric hoist 12. The clamping mechanism is moved to a suitable position, the thumb presses on the support handle 11, and the remaining fingers grip the handle 10. Force is applied to move the handle 10 towards the support handle 11, reducing the opening angle between the second gripping arm 4 and the first gripping arm 3. The overall width of the two hooks 6 is smaller than the inner diameter of the wheel's center hole. The hooks 6 are passed through the wheel's center hole, and the handle 10 is slowly released. The spring 8 shortens and returns to its original position, increasing the opening angle between the second gripping arm 4 and the first gripping arm 3. The overall width of the two hooks 6 is greater than the inner diameter of the wheel's center hole, thus gripping the wheel. The wheel is lifted by the electric hoist 12. After lifting, the support plate 2 and the wheel are usually slightly tilted, with the end of the support plate 2 closest to the spring 8 at its highest point. The two hooks 6 rest against the end face of the wheel. The second and first linear drive components achieve horizontal displacement of the wheel, transferring it to the designated position before lowering it.
