Description

Technical Field

[0001] This utility model relates to the field of hoisting tooling technology, and in particular to a threaded connection hoisting tooling. Background Technology

[0002] With social development and the increasing variety of goods, people are paying more and more attention to the outer packaging of goods. Corrugated paper is one of the important materials for outer packaging of goods, so the demand for corrugated paper is increasing day by day. In order to better cater to consumers, corrugated paper manufacturers are also setting up factories like mushrooms after rain.

[0003] Currently, corrugated rolls are used in corrugated paper production lines. These rolls effectively control the moisture content of the corrugated paper, thus controlling the finishing effect. Therefore, corrugated rolls play a crucial role in the corrugated paper production line. During production, corrugated rolls need to be transferred to different processing equipment. However, corrugated rolls are generally large, making manual handling inconvenient and impractical. Therefore, lifting equipment is required for transfer. However, existing lifting fixtures, in order to ensure safe and stable lifting of corrugated rolls, exert a large clamping force, which can easily damage the outer surface of the end shaft of the corrugated roll, especially the external threads of the end shaft.

[0004] It is evident that existing technologies still need improvement and enhancement. Utility Model Content

[0005] In view of the shortcomings of the prior art, the purpose of this utility model is to provide a threaded connection lifting fixture, which aims to improve the technical problem that the clamping force of the existing lifting fixture is too large and easily damages the outer side of the end shaft of the corrugated roller.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A threaded connection lifting fixture includes: a collar, a nut, and a lifting ring. The collar is sleeved on the end of a corrugated roller, the nut is screwed onto the end of the corrugated roller and limits the collar on the corrugated roller, and the lifting ring is connected to the outside of the collar.

[0008] The threaded connection hoisting fixture has an outer diameter of the collar that is larger than the outer diameter of the nut, and an inner diameter of the collar that is smaller than the outer diameter of the nut but larger than the outer diameter of the end shaft of the corrugated roller.

[0009] The threaded connection hoisting fixture has a circular inner hole and a circular outer ring.

[0010] The threaded connection hoisting fixture has a circular inner hole and a regular polygonal outer ring.

[0011] The threaded connection type lifting fixture has a mounting hole on the outer side of the collar for installing the lifting ring.

[0012] The threaded connection type lifting fixture includes a lifting ring comprising a parallel section and an angled section. The lower end of the parallel section is welded to the outside of the collar, and the upper end of the parallel section is fixedly connected to the angled section. The angled section is rounded at the included corner.

[0013] Beneficial effects:

[0014] This utility model provides a threaded connection lifting fixture, including a nut, a collar, and a lifting ring. The nut is screwed onto the end shaft of the corrugated roller, the collar is fitted onto the end shaft of the corrugated roller and located below the nut, and the lifting ring is connected to the outside of the collar. When lifting the corrugated roller, first, the collar is fitted onto the end shaft of one end of the corrugated roller, then the nut is screwed onto the external thread of the end shaft of the corrugated roller and tightened. Finally, it is connected to the lifting equipment via the lifting ring. This threaded connection lifting fixture, by setting the nut to connect with the thread of the end shaft of the corrugated roller, ensures that the collar is limited by the nut during lifting, allowing the corrugated roller to be lifted and transported safely and stably, while also preventing excessive clamping force from damaging the outer surface of the end shaft of the corrugated roller.

[0024] Example 1.

[0025] Please see Figures 1 to 2 As shown, this utility model provides a threaded connection lifting fixture, which includes: a collar 1, a nut 2, and a lifting ring 3. The collar 1 is sleeved on the end of the corrugated roller, the nut 2 is screwed onto the end of the corrugated roller and limits the collar 1 on the corrugated roller, and the lifting ring 3 is connected to the outside of the collar 1. In this embodiment, the collar 1, nut 2, and lifting ring 3 are all made of metal. The inner diameter of the collar 1 and the internal thread of the nut 2 can be matched and designed according to the end shaft diameter and external thread of the corrugated roller. When lifting the corrugated roller, first, the collar 1 is sleeved on the end shaft of one end of the corrugated roller, then the nut 2 is screwed into the external thread of the end shaft of the corrugated roller and tightened, and finally, it is connected to the lifting equipment through the lifting ring 3. This threaded connection lifting fixture connects the nut 2 to the thread of the corrugated roller end shaft itself. During lifting, the collar 1 is limited by the nut 2, ensuring that the corrugated roller can be lifted and transported safely and stably. At the same time, it can prevent the clamping force from being too great and damaging the outer side of the end shaft of the corrugated roller.

[0026] Please see Figures 1 to 2 As shown, the outer diameter of the collar 1 is larger than the outer diameter of the nut 2 so that the lifting ring 3 is not interfered with by the nut 2 when it is connected to the outer side of the collar 1. The inner diameter of the collar 1 is smaller than the outer diameter of the nut 2 and larger than the outer diameter of the end shaft of the corrugated roller, so that when the corrugated roller is lifted, the collar 1 is limited by the nut 2 and does not detach from the corrugated roller, thereby stably lifting the corrugated roller and not pressing on the outer side of the corrugated roller.

[0027] Please see Figures 1 to 2 As shown, the inner hole of the collar 1 is circular, and the outer ring of the collar 1 is circular, that is, the collar 1 is a ring with a certain thickness in order to connect the lifting ring 3 and improve stability.

[0028] Please see Figures 1 to 2As shown, the lifting ring 3 includes a parallel section 31 and an angled section 32. The lower end of the parallel section 31 is welded to the outer side of the collar 1, and the upper end of the parallel section 31 is fixedly connected to the angled section 32. The angled corner of the angled section 32 is rounded. In this embodiment, the parallel section 31 and the angled section 32 of the lifting ring 3 are an integral structure. The angled section 32 reduces the connection position between the lifting ring 3 and the lifting equipment, thereby preventing the lifting ring 3 from sliding relative to the lifting equipment and maintaining the stable handling of the corrugated roller. The rounded corner helps to improve the strength of the contact position between the lifting ring 3 and the lifting equipment, preventing the lifting ring 3 from being subjected to concentrated force and breaking.

[0029] Example 2.

[0030] Please see Figure 3 As shown, the inner hole of the collar 1 is circular, and the outer ring of the collar 1 is a regular polygon. In this embodiment, the regular polygon includes symmetrical regular polygons such as squares and regular hexagons, so as to symmetrically connect the lifting rings 3.

[0031] The rest of this embodiment is the same as that in Embodiment 1. Features not explained in this embodiment are explained using the methods in Embodiment 1, and will not be repeated here.

[0032] Example 3.

[0033] Please see Figure 4 As shown, the outer side of the collar 1 is provided with a mounting hole 11, which is used to install the lifting ring 3. In this embodiment, the lifting ring 3 is a universal lifting ring 3, which facilitates connection with lifting equipment.

[0034] The rest of this embodiment is the same as that in Embodiment 1. Features not explained in this embodiment are explained using the methods in Embodiment 1, and will not be repeated here.

[0035] In summary, by setting the nut 2 to be connected to the thread of the corrugated roller end shaft, the collar 1 is limited by the nut 2 during hoisting, which ensures that the corrugated roller can be hoisted and transported safely and stably, and at the same time can prevent the outer surface of the end shaft of the corrugated roller from being damaged due to excessive clamping force.

[0036] It is understood that those skilled in the art can make equivalent substitutions or changes based on the technical solution and inventive concept of this utility model, and all such substitutions or changes should fall within the protection scope of the appended claims of this utility model.
