Description

Technical Field

[0001] The utility model relates to a rim hoisting tooling. Background Technique

[0002] A rim, also often referred to as a wheel hub or a wheel rim, is an important component in a wheel system. Its main function is to connect the tire and the axle, support and maintain the shape of the tire, and ensure the stability and safety of vehicle driving.

[0003] Rims are usually heavy, and their circular structure makes it difficult to directly clamp or hoist them. Traditional hoisting methods may include using ropes, chains or simple fixtures to fix and move the rim, but these methods often have problems such as low safety, complex operation and poor stability. Content of the Utility Model

[0004] The main purpose of the utility model is to provide a rim hoisting tooling to solve the problems raised in the above background technique.

[0005] The purpose of the utility model can be achieved by adopting the following technical solutions:

[0006] A rim hoisting tooling includes a central column. A plurality of first connecting rods are rotatably connected to the bottom of the central column along its circumferential direction. A moving disk is sleeved on the central column. A plurality of second connecting rods are fixedly connected to the bottom of the moving disk along its circumferential direction. A plurality of inner support plates are arranged on the outer side of the central column. The first connecting rods and the second connecting rods are respectively rotatably connected to the inner support plates. A support column is arranged above the moving disk. A top plate is arranged above the support column. A moving column is arranged below the top plate. A slot for moving the moving column is arranged on the central column. Limiting slots are arranged on the side walls of the central column on both sides of the slot. Limiting screws passing through the limiting slots are arranged on both sides of the moving column. Limiting nuts are arranged on the limiting screws.

[0016] The beneficial technical effects of the present utility model:

[0017] 1. For the lifting tooling provided by the present utility model, when the inner support plate abuts against the inner wall of the rim, the position of the limiting screw can be fixed by using the limiting nut, thereby restricting the movement of the moving column and the moving disk, so that they cannot drive the inner support plate to move, preventing problems such as vibration during lifting, resulting in the up and down shaking of the inner support plate and inability to tightly support the rim, and improving stability and safety.

Detailed implementation manners

[0026] To make the technical solutions of the present utility model clearer and more definite to those skilled in the art, the present utility model will be further described in detail below in conjunction with embodiments and the accompanying drawings. However, the implementation manners of the present utility model are not limited thereto.

[0027] As Figures 1-6 shown, the rim hoisting tooling provided in this embodiment includes a central column 1. A plurality of first connecting rods 2 are rotatably connected to the bottom of the central column 1 along its circumferential direction. A moving disk 3 is sleeved on the central column 1. A plurality of second connecting rods 4 are fixedly connected to the bottom of the moving disk 3 along its circumferential direction. A plurality of inner support plates 5 are arranged on the outer side of the central column 1. The first connecting rods 2 and the second connecting rods 4 are respectively rotatably connected to the inner support plates 5. The first connecting rods 2 are connected to the bottoms of the inner support plates 5, and the second connecting rods 4 are connected to the tops of the inner support plates 5. A support column 6 is arranged above the moving disk 3, a top plate 7 is arranged above the support column 6, and a moving column 8 is arranged below the top plate 7. A slot 9 for moving the moving column 8 is arranged on the central column 1. Limiting grooves 10 are arranged on the side walls of the central column 1 on both sides of the slot 9. Limiting screws 11 passing through the limiting grooves 10 are arranged on both sides of the moving column 8, and limiting nuts 12 are arranged on the limiting screws 11.

[0028] When in use, loosen the limiting nut 12, push the central column 1 upward, so that the first connecting rod 2 drives the inner support plate 5 to rotate along the connection part of the inner support plate 5 and the second connecting rod 4, thereby contracting inward, and it can be inserted into the inside of the rim. Then lower the central column 1, so that the inner support plate 5 rotates outward, thereby tightly adhering to the inner wall of the rim. Then tighten the limiting nut 12 to prevent the position of the inner support plate 5 from changing and affecting the hoisting effect.

[0029] In this embodiment, as Figure 1 shown, four first connecting rods 2, four second connecting rods 4 and four inner support plates 5 are provided, ensuring the balance and stability of the tooling when hoisting the rim. The four evenly distributed connection points help to disperse the weight of the rim, reducing the instability and potential sliding risks caused by uneven loading.

[0030] In this embodiment, as Figure 1 shown, four support columns 6 are provided. The four support columns 6 are arranged on the moving disk 3 and are evenly distributed along its circumferential direction. The four support columns 6 provide additional support points, enhancing the structural strength and stability of the entire tooling. The even distribution ensures the balance of force distribution and makes the hoisting process smoother.

[0031] In this embodiment, as Figure 1 shown, a limiting disk 13 is arranged above the moving disk 3 on the central column 1, and through holes 14 for the support columns 6 to pass through are arranged on the limiting disk 13, preventing the central column 1 from moving excessively and affecting the hoisting effect.

[0032] In this embodiment, as Figure 1As shown, the upper half of the central column 1 is a cuboid, enabling the limit nut 12 to closely adhere to the outer wall of the central column 1 to ensure the tightening effect. The lower half of the central column 1 is a cylinder, making its movement smoother.

[0033] In this embodiment, as Figure 1 shown, a limit nut groove 15 is provided at the top of the limit groove 10 on the central column 1. When the limit nut 12 is tightened, it will be inserted into the limit nut groove 15. In addition to fixing the position of the limit screw 11 by means of threaded connection, the movement of the limit screw 11 can also be restricted by its own position.

[0034] In this embodiment, as Figure 1 shown, a pull rod 16 is provided on the side wall of the central column 1 between the two limit grooves 10, facilitating the operator to pull the central column 1.

[0035] In this embodiment, as Figure 1 shown, the bottom of the inner support plate 5 is provided with a bending structure that extends outward and downward. During hoisting, the bending structure will support under the edge inside the bottom of the rim, improving the stability of hoisting.

[0036] In this embodiment, as Figure 1 shown, an elastic anti-slip pad 17 is provided on the outer side wall of the inner support plate 5. The elastic anti-slip pad 17 protects the surface of the rim from scratching or damage. At the same time, it increases the clamping force, prevents relative sliding during hoisting, and improves safety.

[0037] In this embodiment, as Figure 1 shown, a lifting ring 18 is provided above the top plate 7 for connecting the lifting hook.

[0038] To sum up, in this embodiment, the hoisting tooling provided in this embodiment can fix the position of the limit screw 11 using the limit nut 12 when the inner support plate 5 abuts against the inner wall of the rim, thereby restricting the movement of the moving column 8 and the moving disk 3 and preventing them from driving the inner support plate 5 to move, avoiding problems such as vibration during hoisting that may cause the inner support plate 5 to shake up and down and unable to tightly support the rim, improving stability and safety; the provided bending structure can support under the inner edge of the rim when hoisting the rim, further enhancing the stability of hoisting.

[0039] The above is only a further embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the scope disclosed by the present invention, according to the technical solution and its concept of the present invention, makes equivalent substitutions or changes, all belong to the protection scope of the present invention.
