TECHNICAL FIELD This invention relates to the technique of the rope sling which twisted the tip of a wire rope and made it into wheel shape. Especially, when making the wheel shape by folding the tip of a wire rope, it forms on the surface of the main line of a wire rope. Improved safety by preventing the cutting cross section of the wire strand called the whiskers appearing on the surface of the main line from being cut off by the so-called beard of the cutting cross section appearing on the surface of the main line of the rope sling. It relates to a method of making a knit rope sling and a knit rope sling.

2. Description of the Related Art [0002] Conventionally, wire ropes used in the manufacture of rope slings are made by arranging six sets of strands in a hexagonal shape around a core and around them, and twisting them in a spiral shape. Each strand is composed of a bundle of inner layer wires of a plurality of wire elements constituting the inner side and a bundle of outer layer wires of a plurality of wire element wires arranged on the outer circumferential side of the inner layer wire.

Conventionally, in the case of producing a rope sling by hand using a wire rope, in the so-called eye processing where the tip of the wire rope is folded back into a wheel shape, the standards set by the law are kept, for example, It is made using a specific squeeze method, called a wrap.

In other words, 6 sets of strands and core nets constituting the wire rope are divided on the end of the folded end, and the end portion is twisted by 6 sets of strands of the main line of the wire rope which becomes the base side to be folded. In a certain time, each strand is passed through in a predetermined order and drawn out from the predetermined interval to form a wheel shape on the end side of the wire rope.

Thereafter, the tip side of the six sets of strands, which are formed in a wheel shape and pulled out from the main line surface of the wire rope, is passed through a specific interval of the strands twisted into the spiral shape of the main line in the order determined by the type of the weaving method. Repeat the process of extracting from a specific particular source at least three times (this is called 'full loading').

After repeating three times or more, the six ends of each of the strands which escaped from the surface of the main ship to the outside are divided into a bundle of outer layer wires and a bundle of inner layer wires, respectively, and the six sets of angles outward from the surface of the main ship The bundle of inner layer wires is cut at the surface position of the main ship.

In addition, the bundles of each of the six sets of outer layer wires, which were not cut, are passed through the specific spaces of the strands twisted on the spiral of the main ship in the order determined by the kind of the above-mentioned weaving method, and are pulled out from the other specific spaces. I repeat my work at least twice (this is called half-putting). Thereafter, the bundles of each of the six sets of outer layer wires that emerge from the surface of the main ship to the outside are cut at the surface position of the main ship.

On the other hand, the order of operation of which strands of each strand or each outer layer wire are passed through and extracted from which is determined by the type of the weaving method. In addition, in the middle of each process, the main wire surface of a wire rope is lightly equalized with a hammer.

Conventionally, rope slings are made by hand using a wire rope by this method.

However, conventional hand-knitted rope slings are a group of wire strands each having a plurality of strengths of bundles of each inner layer wire and each outer layer wire cut at the main wire surface position of the wire rope, and the so-called beard of the cut section is sharpened. However, if your hand touches the beard, it is very dangerous to cut the surface of the hand. In addition, the point of the beard is six places of inner layer wires, and six points of outer layer wires, and a total of 12 points of beards are dispersed on the main wire surface of the wire rope, and therefore, when grabbing the main wire surface of the wire rope, It was dangerous to wear.

In the conventional hand-knitted rope slings, the place of the inner layer wires and the outer layer wire bundles is cut at the main line surface position, but when the bent portion is folded and bent several times, the beard surface is the main line surface. Gradually some protruding from, the protruding beard was very dangerous, in some cases tearing off gloves and cutting hands.

In addition, in the case where the conventional hand-knitted rope sling is pulled out, the beard becomes opposite to the direction in which the wire rope is twisted and the beard is generated from the main surface, and the beard partially protrudes from the main surface and the beard is protruding. In some cases, tearing the gloves could cut your hands, which was very dangerous.

In addition, in the case where the choke was suspended, the conventional hand-knitted rope sling 101 bent the hand-knitted portion of the wire rope 102 on which the bag 104 was wound, and many beards 103 came out and were more dangerous (see FIG. 11). In addition, while the rope sling 111 of the conventional lock processing, which is not hand-knitted, does not have a problem of whiskers, when the wire rope 112 is pulled out by hanging the choke, the portion of the lock processing 113 is loaded 114 ), It was difficult to pull out the wire rope 112 (refer FIG. 12 (A)). Similarly, in the conventional rope processing sling 111, which is not hand-knitted, the portion of the lock processing 113 hits the bag 114, and the bag 114 is often damaged (see Fig. 12 (B)).

In view of the above problems, the present invention was devised to solve the above problems, and an object of the present invention is to cut a cross section of a wire strand called a whisker which appears on the main line surface of the rope sling freely on the main line surface. The present invention provides a method of making a hand-knitted rope sling and a hand-knitted rope sling which can prevent the hand from being cut by the so-called beard of the cut section appearing on the surface of the main line of the hand-knitted rope sling and improve safety.

In order to achieve the above object, the method of manufacturing a knitted rope sling according to claim 1 of the present invention, in the method of manufacturing a knitted rope sling using a wire rope, the end of the wire rope according to the order of the conventional weaving method After making the wheel shape on the side and repeating the whole number of times that the end of the six sets of strands constituting the wire rope pass through the main rope surface of the wire rope a predetermined number of times, it is pulled out from the main rope surface of the wire rope. Each of the six sets of strands is divided into bundles of two wires, and the bundle of one wire wire divided into two is cut to the desired length from the main wire surface, respectively, and the bundle of the first cut wire wires after cutting is cut on the other side. According to the order of the conventional weaving method together with the bundle of the first uncut wire element Pass the cut end surface of the bundle of the first cut wire strands into the hollow formed by drawing a part of the core of the inner line of the wire rope, and pass only the bundle of the first uncut wire strands. After repeating the half-loading operation to remove the wire rope from the main wire surface according to the order of the loading method a predetermined number of times, the bundle of the six sets of each of the first uncut wire strands drawn out from the main wire surface of the wire rope to the outside Cut a part of the core inside the main line of the wire rope and cut a cut section of the bundle of the second cut wire strands after cutting the wire into the desired length before inserting a part of the core inside the main line of the rope into the hollow part.

Repeat a predetermined number of times, for example twice. In the case where the total filling operation is three times, more than two half loading operations are required by Japanese law. At this time, when the total filling operation is four times, the half-putting operation is required one or more times in Japanese law.

Six sets of each of the first non-cut wires drawn out from the surface of the main wire 11a of the wire rope 11 after the operation of half the bundle of the first non-cut wires 1b to 6b twice. The bundles of element wires 1b to 6b are bound together in one piece, and the bundles of the third uncut wire element wires 16c bound together in one piece are cut from the surface of the main wire 11a to a desired length. The desired length is the length which can fully be inserted in the hollow part 11b which pulled out a part of the core net 7 inside the main line 11a. Produced by inserting the cut end surface 16X of the bundle of the 3rd cutting wire element wire 16c after cutting into the hollow part 11b which pulled out a part of the core net 7 inside the main line 11a of the wire rope 11. do. On the other hand, the 2nd cutting wire element wire of Claim 1 corresponds to the 3rd cutting wire element wire 16c after cutting | disconnection.

In addition, there is also a method of making a rope sling by hand in another order, replacing only the order of the last line of 15, 13, 13, 16, and 16, in the same order from the third line to the third line to the fifteenth line.

That is, after performing half a batch operation of only the bundle of the 1st non-cutting wire strands 1b-6b twice, each of 6 sets of 1st non-cutting wire strands pulled out from the main line surface of the wire rope 11 ( The bundle of 1b to 6b is divided into a bundle of two wires 1d to 6d and a bundle of wires 1e to 6e, respectively, and the bundle of one wire wires 1d to 6d divided into two main surfaces From each to the desired length. The desired length is the length which can fully be inserted in the hollow part 11b which pulled out the core part 7 inside the main line 11a.

According to the procedure (8)-(13) of the said weaving method with the bundle of the 4th non-cutting wire strand 1e-6e of one bundle of the 4th cutting wire strand 1d-6d after cutting, The wire rope 11 is passed through the surface of the main line 11a.

At this time, the bundle of the 4th cutting wire strands 1d-6d is the hollow part 11b which cut | disconnected the cut end surface 16X and the core part 7 inside the main line 11a of the wire rope 11. Plug it in.

Then, only the bundles of the fourth uncut wires 1e to 6e are removed from the surface of the main line 11a of the wire rope 11 again in accordance with the procedures (8) to (13) of the above-described weaving method. Repeat the desired number of times, for example 1 to 2 times.

Thereafter, the bundle of six sets of each of the fourth uncut wires 1e to 6e drawn out from the surface of the main line 11a of the wire rope 11 is bound to one, and the fifth bound to one. The bundle of the uncut wire strands 16f is cut from the surface of the main wire 11a to a desired length. The desired length is the length which can fully be inserted in the hollow part 11b which pulled out a part of the core net 7 inside the main line 11a. Produced by inserting the cut end face 16X of the bundle of the 5th cut wire element 16f after cutting into the hollow part 11b which pulled a part of core net 7 inside the main line 11a of the wire rope 11, and was cut out. do. On the other hand, the 2nd cutting wire element wire of Claim 1 corresponds to the 5th cutting wire element wire 16f after cutting | disconnection.

In addition, this invention is not limited to the best form for implementing the said invention, Of course, various changes can be made in the range which does not deviate from the mind of this invention. In the best mode for carrying out the present invention described above, the conventional weaving method has been described in accordance with the order of the weaving method. However, the present invention is not limited thereto, and for example, a winding method or the like may be used.

As is clear from the above description, according to the present invention, the bundles of wire wires woven into the wire rope main wire are all cut from the main wire surface of the wire rope to a desired length, and the cut end surface of the bundle of cut wire wire wire after cutting is cut into the wire rope. Since a part of the core net inside the main ship was inserted into the hollow portion formed, the so-called beard of the cut section of the wire strand bundle can be reliably prevented from appearing on the main ship surface of the wire rope. As a result, even when the glove is not required to be worn and the main wire surface of the wire rope is directly held by bare hands, the rope sling can be handled safely and freely without hand cutting.

In addition, since the cut cross section of the wire strand bundle is inserted in the hollow part which pulled out a part of the core wire inside the wire rope main wire, even if it bends the main wire of the wire rope of a rope sling by hand, the so-called beard does not appear on the surface of the main wire. Similarly, in the case where the rope sling is pulled out by hand, the beard becomes opposite to the direction in which the wire rope is twisted and no beard is generated from the main surface.

In addition, as is apparent from the results of the strength test, the knitted rope sling produced by the method of the present invention has the same strength as that of the conventional manufacturing method, and the strength of the knitted rope sling is sufficiently secured. I can use it in peace. It has a very new and beneficial effect.
