Description

Technical Field

[0001] The utility model relates to the field of hoisting equipment, in particular to a transfer multi-claw hook. Background Art

[0002] Due to the complexity of the process during the production of castings, transfer is required. Small castings are generally transported by transfer carts, while large castings need to be hoisted by cranes. Conventional hoisting hooks are all single-hook structures, and each hoisting can only lift a single casting. This undoubtedly increases the number of hoistings, reduces work efficiency, and increases the labor intensity of workers. Therefore, this application proposes a transfer multi-claw hook to solve the above problems. Content of the Utility Model

[0003] Aiming at the existing problems, the utility model provides a transfer multi-claw hook, which can effectively solve the problems proposed in the background art.

[0004] To solve the above problems, the utility model adopts the following technical solutions:

[0005] A transfer multi-claw hook, which includes a lifting ring, a chain and a hook. The chain is provided in multiple numbers and one end of the chain is connected to the lifting ring, and the other end of the chain is connected to the hook. All the hooks are connected by a spacing adjusting member, and the spacing adjusting member adjusts the distance between adjacent two hooks.

[0006] As a further scheme of the utility model: the spacing adjusting member includes a lead screw, and multiple groups of nuts are threadedly connected to the lead screw. Each group of nuts is provided with two and is symmetrically arranged, and the two nuts of each group are located on both sides of the hook.

[0007] As a further scheme of the utility model: a rubber pad is provided on the side of the nut close to the hook.

[0008] As a further scheme of the utility model: a strip groove is provided on the hook, and the lead screw passes through the strip groove.

[0009] As a further scheme of the utility model: the lead screw is a linear lead screw.

[0010] As a further scheme of the utility model: limiting blocks are fixedly connected to both ends of the lead screw.

[0011] As a further scheme of the utility model: hook holes are provided on the lifting ring and are distributed in a circumferential manner, and one end of the chain is hooked to the hook hole through a hook.

[0012] Compared with the prior art, the beneficial effects of the utility model are as follows: by arranging a plurality of chains on the lifting ring to connect the hooks, multiple castings can be lifted at one time, reducing the number of hoisting times and greatly improving the work efficiency. Moreover, the provided spacing adjusting member can adjust the distance between the two hooks according to castings of different sizes, avoiding collisions between the castings.

[0018] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present utility model.

[0019] Combined Figures 1 to 4 To illustrate this embodiment, this embodiment provides a transfer multi-claw hook, which includes a lifting ring 1, a chain 2 and a hook 3. The chains 2 correspond to the hooks 3 one by one. Five chains 2 are provided. One end of the chain 2 is connected to the lifting ring 1, and the other end of the chain 2 is connected to the hook 3. All the hooks 3 are connected by a spacing adjusting member, and the spacing adjusting member adjusts the distance between adjacent two hooks 3.

[0020] The spacing adjusting member includes a lead screw 4. A plurality of groups of nuts 5 are threadedly connected to the lead screw. Each group of nuts 5 is provided with two and is symmetrically arranged. The two nuts 5 in each group are located on both sides of the hook 3. The nuts 5 limit the hook 3 in the horizontal direction to ensure the distance between adjacent two hooks 3. Moreover, a rubber pad 6 is provided on the side of the nut 5 close to the hook 3, which plays a shock-absorbing role through the rubber pad 6 and can also prevent the nuts 5 from slipping.

[0021] A slot 7 is provided on the lifting hook 3, and the lead screw 4 passes through the slot 7. The lead screw 4 is a linear lead screw, and the slot 7 is arranged along the length direction of the chain 2. When the lifting hook 3 is adjusted, it can ensure that the chain 2 is always in a stressed state. Moreover, limit blocks 8 are fixedly connected to both ends of the lead screw 4 to limit the position by using the limit blocks 8 to prevent the nut 5 from slipping off the end of the lead screw 4.

[0022] Hook holes 9 distributed in a circular pattern are provided on the lifting ring 1. One end of the chain 2 is hooked to the hook hole 9 through a hook 10, which ensures that the force is concentrated on the vertical line of the lifting ring 1 and improves the force-bearing performance.

[0023] The working principle of the present utility model is as follows: By arranging a plurality of chains 2 on the lifting ring 1 to connect the lifting hooks 3, multiple castings can be lifted at a time, reducing the number of hoisting times and greatly improving the work efficiency. Moreover, the provided spacing adjusting member can adjust the distance between the two lifting hooks 3 according to castings of different sizes to prevent collisions between the castings.

[0024] It should be noted that in this article, relational terms such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the term "comprising", "including" or any other variant thereof is intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements not only includes those elements, but also includes other elements not expressly listed, or further includes elements inherent to such process, method, article or device.

[0025] Although the embodiments of the present utility model have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present utility model. The scope of the present utility model is defined by the appended claims and their equivalents.
