Treating structure for sling rope weaving and inserting terminal

Abstract

A processing structure for the braiding end of a sling, using a protective wire forming device composed of a loading part mounted on a rotary driving tool and a forming part for forming a protective wire, formed when the end of the wire rope is twisted and braided After inserting the above-mentioned protective wire from the end of the steel rope forming the collar, bend the part of the steel rope near the end, and weave its end into the twisted part of the steel rope, and insert the protective wire In this weaving part, both ends of the protective wire are processed, and at the same time, the protective wire is fixed with synthetic resin. The processing structure of the braided end of this sling can simply be loaded with a protective wire covered by the braided part exposed at the cut end on the sling collar, and can greatly improve the safety of the loaded protective wire. durability.

Description

technical field [0001] The present invention relates to a sling used for hanging heavy objects on a hook of a crane or an elevator, and more particularly to a processing structure for knitting end portions of slings forming ring-shaped parts used for hanging on the hook . Background technique [0002] Generally speaking, the sling for this kind of hook is used to form a loop at both ends of the cable, as its forming method: [0003] (1) Make both ends of the wire rope stretched in parallel, and crimp and fix this part with a crimping sleeve (locking process). [0004] (2) The method of weaving and inserting strands and wire harnesses called splicing collars (sweet potato-shaped processing) is a common method. [0005] However, the disadvantage of the locking processing method of (1) above is that the crimped sleeve is very hard and not easy to bend, so it is weak and easy to damage against external pressure, or due to the use method or environment caused by the use conditi...

AI Technical Summary

Problems solved by technology

[0011] But, on the weaving and inserting part that above-mentioned cut-off end exposes, the structure that shrinks the heat-shrinkable sleeve is wrapped, because the thickness of the heat-shrinkable sleeve is thin, wear resistance is poor, so will soon wear or bruise and cause damage. is broken, has issues affecting its durability

[0012] In addition, in the method of winding the steel wire and covering the braided part exposed at the cut end, if a part of the steel wire wound at the braided part is cut off, durability problems will arise due to unraveling.
