Description

Technical Field

[0001] The utility model relates to the technical field of wire rope slings, in particular to a wear-resistant wire rope sling. Background Art

[0002] Wire rope slings refer to force-bearing tools that are tied between lifting machinery and the object being lifted in order to achieve the object movement. They are used for lifting, pulling, tightening and carrying in the material handling process. Wire ropes are high in strength, light in weight, stable in operation, not prone to sudden whole-piece breakage, and reliable in operation. They are a consumable material that is used in large quantities in production and life. Since wire ropes are easily worn out during use and have a short service life, wear-resistant wire rope slings are needed to save costs.

[0003] According to the description of a wire rope sling capable of reducing wire rope loss disclosed in the patent website (authorization announcement number: CN218931449 U), "The utility model discloses a wire rope sling capable of reducing wire rope loss, including a sling, a wire ring and a wire rope. The sling is provided with a wire ring inside, and the wire ring is fixedly installed with the sling. The lower end of the wire ring is fixedly welded with a wire rope, and the bottom of the wire rope is fixedly welded with the wire ring. Before use, a wire ring with high rigidity is used to replace the traditional method of bundling with a wire rope. First, the wire ring is sleeved on the fixed block of the sling, and the ring adjustment area is divided into three parts by the fixed block, which can not only prevent the wire ring from sliding, but also can be placed in different areas according to different needs. A clamping sleeve is used at the welding point between the wire ring and the wire rope to tighten the entire connection to play a fixing role. After that, a rubber sleeve is used to make a layer of ring sleeve on the outside of the entire wire rope to prevent wind and sand or acid rain from corroding the external wire rope and causing the wire rope to break and cause a construction accident."

[0004] In view of the above description, the applicant believes that there are the following problems:

[0005] During the use of the utility model, since the device divides the ring adjustment area into three parts through the set fixed block, it can not only prevent the wire ring from sliding, but also place the wire ring in different areas according to different needs. However, the position of the fixed block is fixed and cannot be adjusted according to the size of the wire ring. If the wire ring is small, the wire ring will swing between the fixed blocks, resulting in instability of the hoisted object and the inability to stably fix the wire ring. Therefore, it is necessary to improve a wear-resistant wire rope sling to solve the above problems. Utility Model Content
