Abstract
Description
Technical Field
[0001] The utility model relates to the field of special sling design, and mainly relates to an inner-support sling for conical workpieces. Background Art
[0002] At present, for large conical workpieces with all machined surfaces, there are no lifting lugs on the workpieces and no lifting points are designed. Therefore, existing slings cannot be used for lifting. In view of the above situation, currently, hooks are mostly used for lifting large conical workpieces. However, since there are many cutting edges on the workpieces, using hooks is likely to cause damage to the workpiece surface. Moreover, during the lifting process with hooks, it is unstable and the workpiece is likely to fall. Using slings not only easily damages the slings but also the length of the slings is limited and cannot wrap around the large conical workpiece for a full circle. Therefore, traditional slings cannot be used to lift large conical workpieces. Therefore, there is an urgent need for a safe and effective method to realize the operation of large conical workpieces, and it is particularly important to design an inner-support sling for large conical workpieces. Summary of the Utility Model
[0003] Based on the above problems, the utility model proposes an inner-support sling for conical workpieces, which solves the problem of the inability to lift large conical workpieces without lifting lugs, prevents quality problems such as mechanical damage and knocking during the lifting process of the workpieces, and eliminates potential safety hazards while ensuring the quality of the workpieces.
[0004] An inner-support sling for conical workpieces includes: a cross beam, a connecting plate, and a lifting lug. The cross beam includes a first cross beam and a second cross beam arranged in parallel. The first cross beam and the second cross beam are movably arranged below the connecting plate. Tapers are formed on both sides of the first cross beam and the second cross beam. The lifting lug is arranged above the connecting plate.
[0005] In one embodiment, the thickness of the first cross beam and the second cross beam is 30 mm - 80 mm, and the width is 100 mm - 300 mm.
[0006] In one embodiment, the taper on both sides of the first cross beam and the second cross beam is greater than the taper of the inner circle of the conical workpiece, and the taper difference is 1° - 5°.
[0007] In one embodiment, the minimum diameter of the first cross beam and the second cross beam is greater than the inner circle diameter of the conical workpiece.
[0008] In one embodiment, the first cross beam and the second cross beam are concentric with the conical workpiece.
[0009] In one embodiment, the first cross beam and the second cross beam can move towards each other in the horizontal direction.
[0010] In one embodiment, tracks are arranged below the connecting plate.
[0011] In one embodiment, the number of the lifting lugs and the connecting plates is both 2.
[0012] In one embodiment, the centers of the two lifting lugs are fixed on the two connecting plates on both sides above the cross beam at equal distances along the center of the cross beam.
[0013] The technical solution adopted by the present utility model can achieve the following beneficial effects:

[0020] To facilitate the understanding of the present utility model, the present utility model will be described more comprehensively below with reference to the relevant drawings. The preferred embodiments of the present utility model are shown in the drawings. However, the present utility model can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, these embodiments are provided so that the disclosure of the present utility model can be understood more thoroughly and comprehensively.
[0021] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the technical field to which the present utility model belongs. The terms used in the description of the present utility model herein are only for the purpose of describing specific embodiments and are not intended to limit the present utility model. The term "and / or" used herein includes any and all combinations of one or more of the related listed items.
[0022] The present utility model discloses an internal support type lifting tool for conical workpieces, which is applied to the transfer process of large conical workpieces without lifting lugs and lifting points. The internal support type lifting tool for conical workpieces includes a cross beam, a connecting plate and a lifting lug.
[0023] As Figure 1-2 shown, the cross beam includes a first cross beam 2 and a second cross beam 3 which are arranged in parallel. The first cross beam 2 and the second cross beam 3 are movably arranged below the connecting plate 4. Tapers are formed on both sides of the first cross beam 2 and the second cross beam 3, and the lifting lugs 1 are arranged above the connecting plate. Specifically, the first cross beam 2 and the second cross beam 3 are arranged in parallel on the rails below the connecting plate 4, and the lifting lugs 1 are welded above the connecting plate 4. To ensure the balance of lifting, the number of the lifting lugs 1 and the connecting plate 4 is 2, which are respectively evenly arranged above both sides of the two cross beams arranged in parallel, and the distances from the centers of the two lifting lugs 1 to the center of the cross beam are equal.
[0024] As Figure 1 shown, corresponding tapers are provided in the up and down directions on both sides of the first cross beam 2 and the second cross beam 3. To prevent machine damage during the lifting of tapered workpieces, the tapers on both sides of the cross beam need to be greater than the taper of the inner circle of the tapered workpiece, and the taper difference cannot be too large. The taper difference range is 1° - 5°. If the taper exceeding the inner circle is too large, the contact area will be reduced, resulting in stress concentration and easy breakage of the cross beam.
[0025] Furthermore, the thickness of the first cross beam and the second cross beam is 30mm - 80mm, and the width is 100mm - 300mm.
[0026] During the lifting process, to ensure complete contact between the cross beam and the tapered workpiece, generate effective lifting points, and ensure the safety of the lifting process, the circumferential directions of the first cross beam 2 and the second cross beam 3 must be concentric with the inner circle of the tapered workpiece, and its minimum diameter must be greater than the inner circle diameter of the tapered workpiece. Specifically, as Figure 3 shown, the diameter of dimension B is greater than the diameter of the inner circle A of the tapered workpiece.
[0027] To adapt to the lifting of tapered workpieces of different sizes, the first cross beam 2 and the second cross beam 3 can be moved in the horizontal direction, and the tapers on both sides of the first cross beam 2 and the second cross beam 3 are adjusted by profiling grinding, so that the lifting tool firmly clamps on the inner cavity surface of the tapered workpiece.
[0028] When the inner support type lifting tool for tapered workpieces provided by the present utility model is working, two lifting beams of a certain length are fixed on the two lifting lugs 1. By moving the first cross beam 2 and the second cross beam 3 which are arranged in parallel and movably, and adjusting the taper by profiling grinding on both sides of the cross beam to adapt to tapered workpieces of different sizes, the lifting tool is subjected to a downward pressure and a radial force generated by the self - weight of the tapered workpiece, so that the two cross beams firmly clamp on the inner cavity taper surface of the tapered workpiece, generating effective lifting points, ensuring the safety during the lifting process, preventing quality problems such as machine damage and bumping during the lifting of tapered workpieces due to unreasonable lifting, and ensuring the quality of the product. The inner support type lifting tool for tapered workpieces protected by the present utility model application has the advantages of wide application range and high safety performance.
[0029] The technical features of the above-described embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope recorded in this specification.
[0030] The above-described embodiments merely represent several implementation manners of the present utility model. The description thereof is relatively specific and detailed, but it should not be construed as a limitation on the scope of the utility model patent. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present utility model, several modifications and improvements can still be made, and these all belong to the protection scope of the present utility model. Therefore, the protection scope of the present utility model patent shall be subject to the appended claims.
