DETAILED DESCRIPTION

[0050] The following will be combined with the specific implementation of the utility model to clearly and completely describe the technical solution in 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.

[0051] like Figure 1-5 As shown, a double-hub handling sling of the utility model comprises a fixing seat 1, two clamps 2, a connecting frame 3, a lifting lug 4, a self-aligning cylinder 5 and a plurality of operating handles 6.

[0052] The fixing seat 1 is used for carrying the clamp 2 .

[0053] The clamp 2 is used to clamp the wheel hub. The two clamps 2 are relatively arranged on both sides of the fixing seat 1 and are fixedly connected thereto, so that the sling can clamp two wheel hubs at the same time.

[0054] The connecting frame 3 is used to carry the lifting lug 4 , and the connecting frame 3 is slidably arranged on the fixing seat 1 .

[0055] The lifting lug 4 is used to be suspended on a hook of a lifting device, and the lifting lug 4 is fixedly arranged on the connecting frame 3 .

[0056] The self-aligning cylinder 5 is fixedly arranged on one of the fixed seat 1 and the connecting frame 3, and its output end is rotatably arranged on the other of the fixed seat 1 and the connecting frame 3. When one clamp 2 clamps the wheel hub and the other clamp 2 does not clamp the wheel hub, or the two clamps 2 clamp the wheel hubs of different specifications, the telescopic operation of the self-aligning cylinder 5 drives the lifting lug 4 to move to the center of gravity position of the sling, so that the center of gravity of the sling is corresponding to the position of the lifting lug 4 under various working conditions, avoiding the overturning problem of the sling and ensuring the normal operation of the sling.

[0057] There are two commonly used working conditions for the sling, one is that two clamps 2 clamp the wheel hub of the same specification, and the second is that one clamp 2 clamps the wheel hub and the other clamp 2 does not hold the wheel hub. Correspondingly, two lifting ears 4 are provided, one lifting ear 4 is located at the center of gravity of the sling when the two clamps 2 clamp the same wheel hub, and the other lifting ear 4 is located at the center of gravity of the sling when one of the clamps 2 clamps the wheel hub and the other lifting ear 4 does not hold the wheel hub. Therefore, in these two commonly used working conditions, there is no need to adjust the self-aligning cylinder 5, but only switch the lifting ears 4; at the same time, the two lifting ears 4 can also be hung on the hook of the lifting equipment at the same time to improve the stability of the sling.

[0058] In order to realize the sliding of the fixing seat 1 and the connecting frame 3, as Figure 3 As shown, the fixed seat 1 includes a fixed frame 11 and a slide rail 12, and the connecting frame 3 includes a slide seat 31 and a horizontal rod 32, wherein the slide rail 12 is fixedly set on the fixed frame 11; the slide seat 31 is slidably set on the slide rail 12; one end of the horizontal rod 32 is fixedly set on the slide seat 31; the sliding stability of the slide rail 12 and the slide seat 31 is maintained by the sliding cooperation of the two, and of course, the slide rail 12 is preferably set in the horizontal direction.

[0059] The horizontal rod 32 is preferably configured as a round rod-shaped structure, and correspondingly, the lifting ear 4 includes two hoops 41 and a lifting ring 42, wherein the two hoops 41 are relatively arranged on both sides of the horizontal rod 32 and are fixed thereto, and the two hoops 41 form a circular ring shape; the lifting ring 42 is fixedly arranged on the top side of the hoop 41 located at the top, thereby achieving the firm fixation and convenience of disassembly and assembly of the lifting ring 42.

[0060] When clamping wheels of different specifications, the spacing of the clamp 2 needs to be adjusted. In order to achieve this effect, Figure 2 As shown, the fixing seat 1 also includes a first support arm 13, a sleeve 14 and a second support arm 15. The first support arm 13 is fixedly arranged on the fixing frame 11 and fixedly connected to one of the clamps 2; the sleeve 14 is fixedly arranged on the fixing frame 11; the second support arm 15 is fixedly arranged in the sleeve 14 in a slidable manner, and fixedly connected to the other clamp 2. When the distance between the two clamps 2 needs to be increased, the bolts between the second support arm 15 and the sleeve 14 are first loosened, and then the bolts are tightened after sliding. Since the present sling has the function of adjusting the lifting ear 4, the adjustment of the distance between the clamps 2 does not require the setting of a symmetrical and synchronous adjustment mechanism, thereby simplifying the structure of the present sling.

[0061] like Figure 4 and Figure 5As shown, the clamp 2 includes a clamping cylinder body 21, a telescopic end 22, a supporting rod 23, a reinforcing rod 24 and a protective ring 25, wherein the clamping cylinder body 21 is fixedly arranged on the fixing seat 1, and is used to penetrate the cavity in the wheel hub; the telescopic end 22 is slidably arranged on the peripheral side of the clamping cylinder body 21, and after the clamping cylinder body 21 is connected to the air source, it can drive the telescopic end 22 to slide to support the inner wall of the wheel hub, thereby achieving clamping and fixing of the wheel hub.

[0062] The supporting rod 23 and the reinforcing rod 24 are both used to strengthen the fixing firmness of the clamp 2 and the wheel hub. The supporting rod 23 is fixedly set on the telescopic end 22 and is abutted against the top side of the wheel hub; the reinforcing rod 24 is fixedly set on the supporting rod 23, and the reinforcing rod 24 is abutted against the inner side and bottom side of the wheel hub.

[0063] like Figure 5 As shown, the abutting rod 23 includes a horizontal portion 231, a vertical portion 232 and a clamping portion 233, and the reinforcing rod 24 includes a fitting portion 241 and a protruding portion 242, wherein the horizontal portion 231 is fixedly connected to the fixing seat 1 and abuts against the top side of the hub; the vertical portion 232 is fixedly arranged on the horizontal portion 231 and is perpendicular thereto; the clamping portion 233 is fixedly arranged on a side of the vertical portion 232 away from the center line of the clamping cylinder body 21; the fitting portion 241 is fixedly arranged on a side of the vertical portion 232 away from the center line of the clamping cylinder body 21, and a protruding portion 242 is provided on the fitting portion 241 The slot 201 engaged with the engaging portion 233 and the fitting portion 241 are used to abut against the inner side of the wheel hub; the raised portion 242 is fixedly arranged at the lower end of the fitting portion 241 on the side away from the center line of the clamping cylinder body 21, and is used to abut against the wheel hub; the three sides of the wheel hub are abutted and fixed by the horizontal portion 231, the fitting portion 241 and the raised portion 242, which can improve the fixing firmness of the wheel hub, and the engagement of the slot 201 and the engaging portion 233 can improve the fixing firmness of the abutting rod 23 and the reinforcing rod 24 to prevent them from loosening and falling off.

[0064] The protective ring 25 is fixedly arranged on the clamping cylinder body 21, and the supporting rod 23 and the reinforcing rod 24 are located inside the protective ring 25. The setting of the protective ring 25 can not only limit the opening and closing range of the supporting rod 23 and the reinforcing rod 24 to avoid damage to the wheel hub due to excessive opening and closing range, but also can replace the supporting rod 23 to support the top side of the wheel hub, thereby improving the protection performance of the present sling.

[0065] The operating handle 6 is used to be held by the operator to control the movement of the sling, and the operating handle 6 is fixedly arranged on the fixed seat 1; Figure 1As shown, operating handles 6 are provided at at least three positions of the front side, rear side, left side and right side of the clamp 2, and the heights of the multiple operating handles 6 relative to the ground are different, so that the operator can operate the sling at different positions and different heights, thereby improving the operating convenience of the sling.

[0066] The use method of the double-hub handling sling of the utility model is as follows:

[0067] First, hang the lifting ear 4 on the hook of the lifting equipment, then use the movement of the lifting equipment to move the two clamps 2 to the position where the wheel hub is required to be clamped, and make the clamping cylinder body 21 penetrate into the interior of the wheel hub, then control the telescopic end 22 to move, so that the supporting rod 23 and the reinforcing rod 24 can support the wheel hub, finally control the telescopic cylinder 5 to extend and retract, so that the lifting ear 4 is at the center of gravity of the lifting device, and lift and move the lifting device to move the wheel hub to the specified position.

[0068] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention.
