Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of rubber product hoisting, in particular to a sling with adjustable clamping size for lifting strips. Background Technique
[0002] In the mining industry, in order to protect the cylinder body of the ball mill from being worn, lining lifting strips are often used. The lining lifting strips are made of high-density wear-resistant rubber and high-strength steel skeletons. The rubber covers the steel skeletons, and they have the characteristics of large volume and heavy mass. And because it is inconvenient to set hoisting holes on the steel-rubber composite lining lifting strips, it is impossible to directly use hoisting equipment to lift the lifting strips. Traditional manual handling not only requires a large amount of handling, which is time-consuming and laborious, but also the lifting strips with different sizes are likely to slip during handling, resulting in injuries to workers, with relatively large safety hazards. At the same time, since most of the structure of the lifting strips is rubber, if mechanical equipment such as forklifts is used, it is easy to cause damage and deformation of the lifting strips.
[0003] To sum up, a sling with adjustable clamping size for lifting strips is needed to solve the above problems. Content of the Utility Model

The jacks are connected to the lifting ring, and a lifting strip is clamped between the two clamping plates.
[0006] In some embodiments, a plurality of anti-slip nails are arranged on the opposite sides of the two clamping plates.
[0007] In some embodiments, the length of the clamping plate is greater than the width of the clamping part of the lifting strip.
[0008] In some embodiments, the two clamping plates are in an inverted L shape.
[0009] In some embodiments, a rubber pad is arranged on the inner side of the top of the lifting ring.

[0019] In order to make the purpose, technical solution and advantages of the present utility model clearer, the present utility model will be further described in detail below in conjunction with the specific embodiments and with reference to the drawings. It should be understood that these descriptions are only exemplary and are not intended to limit the scope of the present utility model. In addition, in the following description, the descriptions of known structures and technologies are omitted to avoid unnecessarily confusing the concepts of the present utility model.
[0020] See Figures 1-3 Figures 1-3 , a sling for adjusting the clamping size of a lifting bar, comprising a lifting ring 1, a clamping member 2 is detachably connected to the lifting ring 1. The clamping member 2 includes two connecting rods 21. One ends of the two connecting rods 21 are closely attached to each other and are provided with a plurality of jacks 23. The other ends are fixedly connected with clamping plates 22. The jacks 23 are connected to the lifting ring 1, and a lifting bar 3 is clamped between the two clamping plates 22. During use, first select a suitable jack 23 on the connecting rod 21, then install the lifting ring 1. According to the size of the lifting bar 3, select a suitable jack 23, so as to realize the adjustment of the device for lifting bars 3 of different sizes, improve the applicability of the device. Then, the lifting bar 3 is restricted by the two clamping plates 22 pressing against it. Next, the lifting ring 1 is slowly lifted by a lifting device such as a crane. As the lifting ring 1 is lifted, the two connecting rods 21 gradually deflect from the horizontal to the inclined state, thereby driving the two clamping plates 22 to clamp the lifting bar 3. After that, the lifting device lifts the lifting bar 3 and moves it, thus realizing the lifting function of the lifting bar 3. After the transfer of the lifting bar 3 is completed, the lifting device puts down the lifting bar 3. Finally, the two connecting rods 21 return to the horizontal state, so that the two clamping plates 22 no longer clamp the lifting bar 3, and the lifting bar 3 can be taken away.
[0021] In some embodiments, a plurality of anti-slip nails 221 are provided on the opposite sides of the two clamping plates 22. The anti-slip nails 221 increase the friction between the clamping plates 22 and the lifting bar 3, so that the lifting bar 3 will not slip when clamped by the clamping plates 22, improving the lifting stability and safety.
[0022] In some embodiments, the length of the clamping plate 22 is greater than the width of the clamping part of the lifting bar 3. It can increase the contact surface between the clamping plate 22 and the lifting bar 3, thereby enhancing the clamping force of the clamping plate 22 on the lifting bar 3 and making the clamping of the lifting bar 3 by the clamping plate 22 more firm.
[0023] In some embodiments, the two clamping plates 22 are in an inverted L shape. The inverted L-shaped clamping plates 22 can not only stably apply a force inclined towards the lifting ring 1 to the lifting bar 3 when the connecting rod 21 deflects, so as to realize clamping, but also limit the lifting bar 3 and quickly position to improve the clamping speed.
[0024] In some embodiments, a rubber pad is provided on the inner side of the top of the lifting ring 1. The rubber pad can increase the friction between the lifting device and the lifting ring 1 when the operator uses the lifting device, making the lifting ring 1 stable and preventing the lifting bar 3 from shaking when the lifting device lifts the lifting bar 3, and preventing the lifting bar 3 from falling.
[0025] In some embodiments, the sling ring 1 is an industrial-grade D-shaped shackle. The shape design of the D-shaped shackle enables very fast connection and disconnection, which can greatly improve work efficiency. Moreover, it has a simple structure but powerful functions and can be used in cooperation with various slings to meet different lifting and towing requirements.
[0026] This specific embodiment is only an interpretation of the present invention and is not a limitation thereof. After reading this specification, those skilled in the art can make modifications to this embodiment without creative contributions as needed, but as long as they are within the scope of the claims of the present invention, they are protected by the patent law.
