Description

Technical Field

[0001] The present invention relates to the technical field related to rope buckle slings, in particular to a thornless precision-inserted rope buckle sling. Background Art

[0002] Barbless fine-inserted rope buckle rigging is a device composed of barbless fine-inserted wire rope as the main body and special rope buckles for lifting, pulling, tensioning and carrying operations.

[0003] The existing Chinese patent document with publication number CN208150773U discloses a load-increasing steel wire rope sling, which comprises a steel wire rope and a shackle structure formed by bending the two ends of the steel wire rope back and locking them with aluminum alloy fixing sleeves. The two rope ends of the steel wire rope are respectively bent back and extended to intertwine and twist to form a lap joint parallel to the original steel wire rope, and the lap joint is locked in the aluminum alloy fixing sleeve.

[0004] However, the aluminum alloy fixing sleeve lock used to lock the wire rope in the above solution cannot be disassembled, so it cannot be reused. Moreover, when the size of the rope buckle structure needs to be adjusted later, the aluminum alloy fixing sleeve lock needs to be cut. This process not only causes the aluminum alloy fixing sleeve lock to be scrapped, but also the cutting process is likely to damage the wire rope.
