Description

Technical Field

[0001] This utility model relates to the field of hoisting tools, specifically a disc hoisting structure. Background Technology

[0002] In production, we often encounter large, round parts that lack holes and have a small thickness. We want to mount them vertically onto the chuck of a horizontal lathe. Current methods generally fall into three categories: using slings to secure the outer diameter for lifting, using a magnetic disk to lift the large end face of the part, and using vertical steel plate clamps for lifting. Among these, using slings for lifting is the most common, but it still has some shortcomings in practice, such as:

[0003] Lifting slings are mostly made of nylon. Although they have sufficient strength to meet the lifting requirements of workpieces, during the subsequent lifting process, the workpiece is prone to slipping due to the relatively smooth surface of the large round disc parts (or other metal parts waiting to be machined). The stability of the lifting sling is generally average, and the safety performance during operation needs to be improved. In addition, during long-term use, the edges of the lifting sling are often the most prone to wear, which is not conducive to long-term use. Utility Model Content

[0004] The purpose of this utility model is to provide a circular disc hoisting structure to solve the problem mentioned in the background art that, during the subsequent hoisting process, the surface of the large circular disc parts (or other metal parts waiting to be hoisted) is relatively smooth, the workpiece is prone to slipping during the hoisting process, the stability is generally poor, and the safety performance during operation needs to be strengthened.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a circular disc lifting structure, comprising two lifting straps, each end of which is fixedly connected to a first lifting strap ring. The lifting straps are multi-layered structures, comprising: nylon strips, two nylon strips, and a sandwich layer between the two nylon strips. The sandwich layer has multiple protrusions on both its upper and lower surfaces, a portion of which penetrates the nylon strips. The nylon strips are sewn to the sandwich layer by a first sewing thread.

[0006] Preferably, a buckle is provided on both sides of the center between the two straps. The upper and lower ends of the buckle are fitted with second strap rings. The upper and lower second strap rings are respectively fitted and connected to the two straps. The buckle is composed of a U-shaped ring, a bolt and a nut. The outer wall of the U-shaped ring fits against the inner wall of the second strap ring. The upper and lower U-shaped rings are interlocked. A bolt is inserted into the surface of one side of the U-shaped ring. A portion of the bolt passes through the two U-shaped rings in sequence. The portion of the bolt that passes through the two U-shaped rings is threaded with a nut.

[0007] Preferably, a protective component is fitted at the edge of the suspender strap, the protective component comprising: two U-shaped sleeves, the two U-shaped sleeves being respectively fitted at the two side edges of the suspender strap, the U-shaped sleeves being sewn to the suspender strap by a second sewing thread.

[0008] Preferably, the interlayer has multiple reinforcing ribs evenly distributed inside.

[0009] Preferably, both the second sewing thread and the first sewing thread are anti-static sewing threads.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows: This disc hoisting structure has the following advantages over traditional technology:

[0011] By using the sling and the first lifting ring to lift large round disc parts (or other metal parts waiting to be machined), the nylon sling and its protrusions will directly contact the parts. During this process, the protrusions can significantly increase the frictional resistance between the parts and the nylon sling, making it less likely for the parts to slip or shift during lifting. This greatly reduces the risk of the parts falling and enhances the safety of the lifting operation.

[0012] Through the cooperation of the sling strip, the first lifting ring, and the protective components, two U-shaped sleeves are respectively fitted onto the two sides of the nylon strip, which can wrap and protect the edges of the nylon strip, making the edges of the nylon strip less prone to wear during long-term use, thus facilitating long-term safe use.

[0013] By using the coordination of the slings, the first sling ring, the second sling ring, and the locking buckle, two slings can be used in conjunction during the hoisting of large disc-shaped parts. First, place the two slings symmetrically on both sides below the disc-shaped workpiece. After the workpiece is erected, adjust its position appropriately. Then, use an external hook to apply force to the first sling rings at both ends of the slings to make the large disc-shaped part stand upright (with the bottom of the large disc-shaped part separated from the ground). Use the locking buckle to tie the two corresponding second sling rings together. This can further improve the stability of hoisting the large disc-shaped part. Attached Figure Description

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figure 1-4 This utility model provides a technical solution: a circular disc lifting structure, including two lifting straps 1, each end of which is fixed with a first lifting strap ring 2. The lifting straps 1 have a multi-layer structure, including: nylon strips 5, two nylon strips 5 are provided, and a sandwich 6 is provided between the two nylon strips 5. Multiple protrusions 7 are provided on both the upper and lower surfaces of the sandwich 6. A portion of the protrusions 7 penetrates through the nylon strips 5. The nylon strips 5 are sewn to the sandwich 6 by a first sewing thread 8.

[0022] In the specific implementation process, it is worth noting that both the first sling ring 2 and the second sling ring 2 are made of nylon material, which has sufficient strength to meet the requirements of workpiece hoisting. The interlayer 6 is made of rubber material, which has a certain degree of flexibility and can meet the normal and complete deformation of the sling strip 1. In addition, it has a high surface roughness and friction coefficient. The protrusion 7 and the interlayer 6 are integrally formed. The protrusion 7 can be provided with a through hole where it penetrates the nylon strip 5, so as to facilitate the smooth penetration of the protrusion 7 locally and facilitate the production and processing.

[0023] Furthermore, a buckle 4 is provided on both sides of the center between the two slings 1. The upper and lower ends of the buckle 4 are fitted with second sling rings 3. The upper and lower second sling rings 3 are respectively fitted and connected to the two slings 1. The buckle 4 is composed of a U-shaped ring 401, a bolt 402 and a nut 403. The outer wall of the U-shaped ring 401 fits against the inner wall of the second sling ring 3. The upper and lower U-shaped rings 401 are interlocked. A bolt 402 is inserted into the surface of one side of the U-shaped ring 401. A portion of the bolt 402 passes through the two U-shaped rings 401 in sequence. The portion of the bolt 402 that passes through the two U-shaped rings 401 is threadedly connected to the nut 403.

[0024] In the specific implementation process, it is worth noting that the U-ring 401, bolt 402 and nut 403 are all made of stainless steel, which has high strength and is rust-resistant, making it easy to use stably for a long time. Place the two lifting straps 1 symmetrically on both sides below the disc-shaped workpiece. After the workpiece is erected, adjust its position appropriately. Then, use an external hook to apply force to the first lifting strap rings 2 at both ends of the lifting strap 1 to make the large disc-shaped part stand upright (the bottom of the large disc-shaped part is separated from the ground). Use the locking buckle 4 to tie the two corresponding second lifting strap rings 3. This can further improve the stable lifting of the large disc-shaped part.

[0025] Furthermore, a protective component is fitted at the edge of the suspender strip 1. The protective component includes two U-shaped sleeves 9, which are respectively fitted at the two sides of the suspender strip 1. The U-shaped sleeves 9 are sewn to the suspender strip 1 by a second sewing thread 10.

[0026] In the specific implementation process, it is worth noting that the U-shaped sleeve 9 is made of aramid fiber, which has ultra-high strength and is very wear-resistant. Its strength is several times that of steel wire of the same size.

[0027] Furthermore, multiple reinforcing ribs 11 are evenly distributed inside the interlayer 6.

[0028] In the specific implementation process, it is worth noting that the reinforcing rib 11 is made of stainless steel wire. The reinforcing rib 11 can be set inside the sandwich 6 during the forming process, which can improve the overall tensile strength of the strap strip 1.

[0029] Furthermore, both the second sewing thread 10 and the first sewing thread 8 are anti-static sewing threads.

[0030] In the specific implementation process, it is worth noting that the second sewing thread 10 and the first sewing thread 8 are made of conductive carbon fiber and polyester filament, which have high tensile strength. While ensuring the basic stitching connection strength, they can also eliminate static electricity on the sling strip 1 through the corona discharge and leakage effect of the conductive fiber. This makes them suitable for lifting needs in industries such as electronics manufacturing, semiconductor industry, chemical transportation and pharmaceutical production. They have a wide range of applications and are easy to promote and use.

[0031] Working principle:

[0032] Lifting operations for large, disc-shaped parts:

[0033] First, use two lifting straps 1 together. Place the two lifting straps 1 symmetrically on both sides below the disc-shaped workpiece. After the workpiece is upright, adjust its position appropriately. Then, use an external hook to apply force to the first lifting rings 3 at both ends of the lifting straps 1, so that the large disc-shaped part is upright (the bottom of the large disc-shaped part is separated from the ground). Use the locking buckle 4 to tie the two corresponding second lifting rings 3 together, so that the two lifting straps 1 will not slide away from the large disc-shaped part. At this time, drive the external hook to continue to apply force, and the disc-shaped part can be moved to the chuck clamping position. Generally, large disc roughing is done with a four-jaw chuck. The chuck jaws are swung to a 45-degree angle with the vertical direction, and the positioning pins on the chuck are in the vertical direction. The lifting part is attached to the chuck positioning pins. After the jaws are clamped, release the locking buckle 4 in front, lower the hook and pull out the lifting straps 1, etc., and the lifting operation of the disc-shaped part is completed.

[0034] Stable hoisting operation:

[0035] During hoisting, the nylon strip 5 and its protrusions 7 will directly contact the parts. During this time, the protrusions 7 can significantly increase the frictional resistance between the parts and the nylon strip 5, making it less likely for the parts to slip or shift during hoisting, thus greatly reducing the risk of the parts falling. In addition, two U-shaped sleeves 9 are respectively fitted on the two sides of the nylon strip 5, which can wrap and protect the edges of the nylon strip 5, making it less prone to wear on the edges of the nylon strip 5 during long-term use, which is conducive to long-term safe use.

[0036] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
