It includes: a lifting ring, a lifting chain, a hanging part, a pushing device and at least three claws; wherein the hanging part includes a first hanging branch and a second hanging branch, the first hanging branch is provided with a radial groove; the second hanging branch is a truncated cone with a groove on the top, and the outer edge of the groove is provided with the at least three claws. The pushing device includes: a hanging rod, a top rod and a pushing plate. The lifting ring is connected to the lifting chain, and the lifting chain is used to connect the first hanging branch.

[0004] As in the above-mentioned solution, the lifting device lifts the part by holding the bottom surface of the part with the claws. However, after the lifting device enters the inner hole of the part, the claws are prone to scratch the wall of the inner hole, affecting the yield of the finished product. Therefore, it needs to be improved. Utility Model Content

DETAILED DESCRIPTION

[0037] The following will be combined with the implementation of the utility model to clearly and completely describe the technical solutions in the implementation of the utility model. Obviously, the described implementation is only a part of the implementation of the utility model, not all of the implementations. Based on the implementation of the utility model, all other implementations obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0038] like Figures 1 to 8 As shown, the wheel hub hanger of the utility model includes a three-claw cylinder 1, a first guide block 2, a second guide block 3, a connecting block 4, a connecting bolt 5, a first pad 6, a second pad 7, a third pad 8, a handle 9, a control valve box 10, a clamping button 11 and a release button 12.

[0039] like Figures 1 to 3 As shown in 5 to 7, the first guide block 2 is connected to the three-claw cylinder 1 and is coaxially arranged, and the first guide block 2 is used to abut the end face of the wheel hub 100; the second guide block 3 is connected to the three-claw cylinder 1 and is coaxially arranged, the second guide block 3 is away from the three-claw cylinder 1 relative to the first guide block 2, and the second guide block 3 is used to abut the inner hole of the wheel hub 100; the first guide block 2 and the second guide block 3 are both ring-shaped structures, and the inner diameter of the first guide block 2 is larger than the outer diameter of the second guide block 3; the movable claw 101 of the three-claw cylinder 1 passes through the first guide block 2 and the second guide block 3;

[0040] As in the above structure, when the wheel hub 100 is clamped, the lifting device is guided by the first guide block 2 and the second guide block 3, the second guide block 3 enters the inner hole of the wheel hub 100 and abuts against the wall of the inner hole, and the first guide block 2 abuts against the end face of the wheel hub 100, so as to prevent the movable claw 101 of the three-claw cylinder 1 from scratching the inner hole of the wheel hub 100. After the movable claw 101 enters the inner hole of the wheel hub 100 through the guidance, the inner hole of the wheel hub 100 is tightened by the movable claw 101 of the three-claw cylinder 1 to achieve lifting.

[0041] like Figure 2 and Figure 3 As shown, the connecting block 4 is connected to the three-claw cylinder 1, three connecting blocks 4 are provided, and the three connecting blocks 4 and the movable claws 101 are staggered with each other; the first guide block 2 and the second guide block 3 are both connected to the connecting block 4;

[0042] As in the above structure, when installing the first guide block 2 and the second guide block 3, the connecting block 4 and the movable claw 101 of the three-claw cylinder 1 are staggered, and then the first guide block 2 and the second guide block 3 are connected to the connecting block 4. This structure can prevent the setting of the guide blocks from interfering with the movement of the movable claw 101.

[0043] like Figure 1As shown, the connecting bolt 5 passes through the three-claw cylinder 1 and is threadedly connected to the connecting block 4;

[0044] As in the above structure, when installing the connecting block 4, the connecting bolt 5 is passed through the three-claw cylinder 1 and then threadedly connected to the connecting block 4. This structure can avoid interference with the sliding fit structure between the movable claw 101 and the internal cylinder body of the three-claw cylinder 1.

[0045] like Figure 4 and Figure 8 As shown, the first pad 6 is arranged on the side of the first guide block 2 away from the three-claw cylinder 1; the second pad 7 is arranged on the side of the second guide block 3 away from the three-claw cylinder 1;

[0046] As in the above structure, by arranging the first pad 6 and the second pad 7 on the first guide block 2 and the second guide block 3, a buffering protection function can be achieved to avoid scratches when contacting the wheel hub 100.

[0047] Furthermore, the peripheral edges of the first guide block 2 and the second guide block 3 are provided with round chamfers, so as to further prevent the guide blocks from scratching the wheel hub 100 .

[0048] The first pad 6 is an arc-shaped structure, and a plurality of first pads 6 are arranged on the surface of the first guide block 2; the second pad 7 is a ring-shaped structure;

[0049] As in the above structure, the first pad 6 only contacts the end face of the wheel hub 100, so it can be set as an arc-shaped structure. By setting multiple pads, stable support for the end face of the wheel hub 100 can be achieved. The gap between the first pads 6 is also convenient for assembling bolts to connect with the connecting block 4; because the second pad 7 needs to contact the inner hole of the wheel hub inner hole, it is set as a ring-shaped structure to achieve stable support.

[0050] like Figures 1 to 3 As shown, the third pad 8 is covered on the movable claw 101, and an oblique chamfer 801 is provided on the end of the third pad 8 away from the three-claw cylinder 1;

[0051] As in the above structure, in order to further prevent the movable claw 101 from scratching the wheel hub, a third pad 8 is wrapped on the movable claw 101 for protection. By setting an oblique chamfer 801 on the third pad 8, the movable claw 101 can smoothly enter the inner hole of the wheel hub 100.

[0052] like Figures 5 to 7 As shown, the handle 9 is arranged on one end of the three-claw cylinder 1 away from the first guide block 2;

[0053] As in the above structure, the handle 9 is used for moving the lifting device. In specific applications, the handle 9 can be connected to the overhead crane.

[0054] like Figure 1As shown, the control valve box 10 is arranged on the handle 9, and the control valve box 10 is used to install the valve that controls the action of the three-claw cylinder 1;

[0055] As in the above structure, by integrating the valve into the handle 9, the integration degree of the sling can be improved, so that the valve of the control valve box 10 only needs to be connected to the air control pipeline.

[0056] Furthermore, the control valve box 10 is integrated with a clamping button 11 and a release button 12 for controlling the on-off of the valve, thereby improving the convenience of control.

[0057] Specific implementation steps:

[0058] The crane is connected to the handle 9, and the lifting device can be moved by holding the handle 9. During lifting, the movable claw 101 enters the inner hole of the wheel hub 100 through the guidance of the first guide block 2 and the second guide block 3. After the second guide block 3 and the second pad 7 are abutted against the inner hole of the wheel hub 100, and the first pad 6 is abutted against the end face of the wheel hub, the movable claw 101 of the three-claw cylinder 1 is actuated to tighten and fix the inner hole of the wheel hub 100, and then the lifting work can be carried out.

[0059] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
