Method for manufacturing hand-knitting suspension rope and hand-knitting suspension rope

Abstract

This invention provides a hand-knitting sling cable in which wire strand cut end face, so-called mustache which appears on main wire surface of the hand-knitting sling cable is prevented from appearing on the main wire surface and cutting of hand caused by so-called mustache of cut end face which appears on the surface of main wire of the hand-knitting sling cable is surely prevented to enhance safety. Round insertion operations for preparing a ring on the end side of a wire rope 11 and passing top sides of 6 pairs of strands 1-6 though the surface of main wire 11a and pulling out the material are repeated prescribed times and 6 pairs of strands 1-6 are each divided into two wire strand bundles and either one of wire strand bundles divided into two is cut and the cut end face 16X is inserted into a hollow part 11b in the main wire of the wire rope 11 and half-insertion operations of only bundles of first non-cut wire strands 1b-6b are repeated prescribed times and bundles of 6 pairs of first non-cut wire strands are bound to one bundle and one bundle is cut and the cut end face 16X is inserted into the hollow part 11b of the interior of main wire of the wire rope 11.

Description

technical field [0001] The present invention relates to the technology of hand-knitted slings, that is, the technology of making ring-shaped hand-knitted slings by folding back the front end of the wire ropes, and particularly relates to the manufacturing method of the hand-knitted slings and the hand-knitted slings as follows , that is, when the front end of the wire rope is folded back to make a ring shape, the cut end faces of the strands called so-called burrs that appear on the surface of the main wire of the wire do not appear on the surface of the main wire, and reliably prevent the The so-called burr cutting on the surface of the main line of the hand-knitted sling, which is formed by cutting the end face, improves the safety of the hand-knitted sling manufacturing method and the hand-knitted sling. Background technique [0002] Conventionally, wire ropes used in the manufacture of hand-woven slings are produced by arranging a cable core and six groups of wire harnes...

Problems solved by technology

[0010] However, for the previous hand-woven slings, the bundles of each inner layer strand and each outer layer strand that are cut off at the surface of the main line of the steel cable are a collection of strands with a certain strength. , the so-called burrs formed by its cut-off end face are sharp and very dangerous, because if the hand comes into direct contact with the burrs, the surface of the hand will be cut

Moreover, there are six burrs in the inner strands and six in the outer strands, a total of 12. Since these burrs are scattered on the surface of the main line of the steel cable, if you grasp the surface of the main line of the steel cable It's dangerous without gloves

[0011] In addition, in the case of conventional hand-woven slings, at our company, the bundles of the inner and outer strands were cut at the surface of the main wire, but the main wire part where the burrs were scattered was bent many times. During the process, sometimes a part of the burrs will gradually protrude from the surface of the main line. Depending on the occasion, the protruding burrs will sometimes cut gloves and hands, which is very dangerous.

[0012] In addition, when pulling out the previous hand-woven sling, the direction of the burr is opposite to the twisting direction of the wire rope, so the burr will rise from the surface of the main line, and some of the burrs will protrude from the surface of the main line, and sometimes the protruding burr will also It's dangerous to cut your hand with a glove

[0013] In addition, when performing choke hoisting, in the conventional hand-woven sling 101, the hand-woven part of the wire rope 102 that has been wound on the cargo 104 will bend, and many burrs 103 will appear. more dangerous (see Figure 11 )

In addition, for the sling 111 of the conventional locking process that is not hand-knitted, although there is no problem of burrs, when the wire rope 112 is pulled out when the choke is hoisted, the part of the locking process 113 is caught on the cargo 114, It is not easy to pull out the wire rope 112 (see Figure 12 (A))

Equally, for the sling 111 of the prior locking processing of non-hand weaving, the part of its locking processing 113 contacts cargo 114, often damages cargo 114 (referring to Figure 12 (B))
