Description

  The present invention is a wire having no thorns in which the end side of a wire rope is bent into a ring shape and the free end of the bent end is connected and fixed to the wire rope to form a loop-shaped ball hook at the tip of the wire rope. BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a rope sling manufacturing method, a wire rope sling manufacturing device, a thornless wire rope sling manufacturing method using the same device, and a thornless wire rope sling.

  2. Description of the Related Art Conventionally, a metal wire rope is configured such that a plurality of strands of strands, which are strands formed by twisting several metal strands, are twisted to form a rope.

  In order to engage the wire rope with the protrusion, a ring-shaped loop portion is formed at the tip of the wire rope, and the loop portion is engaged with the protrusion.

  Therefore, it is often used by forming such a loop portion at the tip of the metal wire rope, and this loop shape is called a sling rope (see, for example, Patent Document 1).

  Thus, as a method of forming the sled rope of the loop portion, first, for each bundle of strands formed by twisting the free end of the bent wire rope for each bundle of strands, that is, by twisting several metal strands Dissolve in pieces.

  Next, at the position that should be the base end of the loop of the wire rope, a gap between the bundle strands twisted with a needle member called a sharp spiky is opened, and the first strand of the previously separated strands is inserted. Insert through the gap.

  In this way, each separated bundle strand is passed through the different gaps of the twisted strand in the same way, and finally the free ends of all the separated strands are connected to the loop base end of the wire rope. The strand gap formed at the position to be inserted is inserted. Repeating this several times is called a rounding operation.

  After such a rounding operation is performed, the end of each bundle strand protruding through the gap is further branched into two sets of fine bundles, and the first set of fine bundle strands has a desired length from the surface of the wire rope. While cutting, other sets of fine strands that are not cut pass through different strand gaps. Repeating this several times is called half-insertion work.

  In this way, by completing several strand insertion operations and cutting the free end protruding from the gap, the continuous fixing operation of the loop base end of the wire rope is completed and a loop-shaped sling rope is completed (for example, Patent Document 1).

  That is, the wire rope used for the production of a conventional hand-knotted ball rope is made by arranging six pairs of strands in a hexagonal shape around the heart rope and its surroundings, and twisting them in a spiral shape. Is composed of a bundle of a plurality of wire strands constituting the inner side.

  In general, when manufacturing hand-knotted ropes using wire rope, the so-called eye processing that loops the tip of the wire rope into a loop shape follows the standards stipulated by laws and regulations, for example, basket insertion and winding It is made using a specific weaving method called.

  Each twisted strand that is twisted at the base side where the distal end portion is folded, that is, the position that should be the base end of the loop portion, is divided into six bundle strands and core ropes that constitute the wire rope on the folded distal end side The tips of the bundle strands are separated from each other in a predetermined order and are extracted from the determined interval.

  At the base end of the loop part, pass through the ends of the 6 strands of bundled bundles drawn from the main surface of the wire rope in the order determined by the type of weaving method. Repeat at least 3 times to extract from the space.

  After repeating three or more times, the tip side of each of the six separate strands coming out from the surface of the main line is further identified for each set as a fine bundle of outer layer wires and a fine bundle strand of inner layer wires. Then, it is subdivided into two groups to form twelve pairs of free ends of the thin strand strands, and only the six strands of each inner layer wire protruding from the surface of the wire rope to the outside at the surface position of the wire rope Disconnect.

  Further, the six bundles of the outer layer wires that were not cut are passed in between the specific strands of the strands of the wire rope that are twisted in the order determined by the type of the knitting method. Repeat the work of extracting from a specific interval at least twice (this is called "half-insertion work"). Thereafter, the six bundles of outer layer wires extending out from the surface of the wire rope are cut at the surface position of the wire rope.

  In addition, these work procedures to determine from which space each bundle strand or fine bundle strand of each outer layer wire is passed and from which other space are extracted are determined by the type of knitting method. Further, the surface of the wire rope is lightly leveled with a hammer during each step.

  Conventionally, hand-knitted ball ropes have been made using such a method using a wire rope.

  The slinging rope manufacturing technology by braiding that forms and forms a loop-shaped ring on the end side of such a metal wire rope, when the diameter of the wire rope is, for example, 20 mm or more, all processes are performed manually. .

  In order to improve the efficiency of such work, the spiky as a needle member that forms a gap between twisted strands located at the base end of the loop on the wire rope main body side is improved, and the strand bundle is formed at the tip just like a needle of a sewing machine. There is a technique related to spiking in which a hole for free end locking is formed (see, for example, Patent Document 2).

JP 2006-291387 A Japanese Utility Model Publication No. 5-5897

  However, the wire rope terminal processing machine of Japanese Utility Model Laid-Open No. 5-5897 of Patent Document 2 has the following problems.

  That is, in this patent document, the free ends of a bundle of strands that have been separated in advance are locked into the holes at the tip of the spiking, and each twisted strand is The free ends of a plurality of bundle strands that have been released apart while forming a gap therebetween are also simultaneously inserted into the twisted strand gap. Therefore, although the work efficiency is improved, the tip of the spiky becomes larger by the amount of the hole, and if the spiky is inserted between the twisted strands located at the base end of the loop of the wire rope, the peripheral surface of the twisted strand is easily damaged. There was a possibility of causing an accident when using the slinging rope by affecting the strength of the slinging rope of the wire rope.

  In addition, in the conventional general slinging line forming work that does not use such improved spiking, each inner layer wire or each outer layer wire that is cut at the surface position of the wire rope has a plurality of strong wire strands. Therefore, the so-called thorns at the cut portions are sharp, and if the hand directly touches the thorns, the surface of the hand is cut, which is very dangerous. In addition, there are 6 thorns on the inner layer line of 6 fine bundles and 6 outer layer lines on the 6 fine bundles, and the twelve tangles in total are 12 wire ropes by the 12 fine bundle strands branched. Therefore, it was dangerous to wear gloves when grasping the base end surface of the loop portion of the wire rope.

  In addition, in conventional hand-knitted ball hanging ropes, the inner layer wire and outer layer wire bundles are initially cut at the very end of the surface of the main line, but the main line part where the thorns are dispersed may be bent many times. In the meantime, the thorns gradually protruded from the surface of the main line, and the protruding thorns were very dangerous because they sometimes split their gloves and cut their hands.

  In this way, the biggest problem with the sling rope is that the free ends of a plurality of separated strands are inserted through the gap between the twisted strands formed by spiking and the leading end is cut, so that the cut portion protrudes from the peripheral surface of the wire rope. There is a danger that the tip of the cutting part of the unwinding strand becomes sharp during work and there is a danger that the worker may be injured during the work, and further, the free end of the strand of the strand protrudes from the loop base end of the finally completed sling rope Therefore, it is that it was very dangerous for the user who uses the sling rope of the wire rope.

  Therefore, Patent Document 1 describes a method for forming a sled rope so that the protruding free end of the strand does not protrude from the peripheral surface of the wire rope.

  In other words, the cut end face of the wire strand called the thorn that appears on the surface of the main line of the hand-knotted sling rope does not appear on the surface of the wire rope, and the hand is cut by the so-called thorn of the cut end face that appears on the surface of the main line of the hand-knitted sling rope A method for producing a hand-knotted sling that can be surely prevented and improved safety (Patent Document 1) has been filed.

  The method of manufacturing the sling rope described in Patent Document 1 has a technique of pushing into the core gap formed at the center of the wire rope so that the cutting tip of the bundle strand, the so-called thorn, does not protrude from the peripheral surface of the wire rope. Although it is disclosed, there is a possibility that the thorns that are gradually pushed in during use of the wire rope sling rope may protrude from between the twisted strands to the peripheral surface of the wire rope. The reason for this is that the bundle strand to be inserted is always inserted in a constant twisting direction relative to the twist of the wire rope, for example, only in the reverse direction, and the braided strand is inserted. It is considered that the core gap formed by braiding communicates with the peripheral surface of the wire rope and the core gap cannot be made into a thorn storage space, that is, a closed space.

  Furthermore, the technique in which the thorns are stored in the core of the wire rope without protruding from the surface of the wire rope is an epoch-making ball hanging rope. A person who is inserted between the strands at the position to be the loop base end of the rope to form a gap between the strands, a person who inserts a terminal strand which has been released into the gap between the strands, and a gap between the strands Since all processes such as pulling the inserted strand at the same time as the spiky that formed the spigot are carried out by hand, it is necessary to work with three or more workers for thick diameters. Was.

  In addition, the use of spiky for forming gaps in the twisted strands and the handling of the free ends of the loose bundle strands are dangerous, and there is a fact that there is no end to human injury during work.

  Therefore, the inventor of the present application makes it possible to perform this work with a machine, and the free end of the strand finally inserted into the loop proximal end of the sling rope does not gradually protrude from the surface during use of the wire rope. In this way, we have developed a method for manufacturing a wire rope sling rope without wire, a wire rope sling manufacturing device, and a wire rope sled manufacturing method using the same without using a wire rope. .

  That is, the present invention has been devised in view of the above-described problems to solve the problem, and the object of the present invention is to have the free end of the strand project on the surface of the wire rope at the loop base end. An object of the present invention is to provide a wire rope sling manufacturing method capable of producing a wire rope having a sling formed on the end side while maintaining a certain quality without any problem, particularly on the end side of a wire rope having a large diameter Can be processed mechanically, and can be automated as much as possible, and can be processed with the smallest number of workers without any danger, and some wires The present invention provides an apparatus for producing a sling rope that does not break or break the strands, a sled-less wire rope sled production process using the apparatus, and a splinterless wire rope produced by the method.

  The invention described in claim 11 is a wire rope slinging wire without barbs produced by the method for producing a slingless wire rope slinging method according to any one of claims 1 to 3.

  According to the first aspect of the present invention, in inserting a bundle strand or a thin bundle strand between twisted strands at the loop base end portion of the wire rope, first, the bundle is aligned along the twist in the same direction as the twist of the wire rope. The strands are knitted by inserting the strands between the strands. This operation is performed several times, then the bundle strands are knitted along the direction opposite to the twisting of the wire rope, and then separated into inner layer wires and outer layer wires. The outer layer wire after being inserted is knitted by being inserted between the twisted strands in the direction opposite to that of the wire rope. Therefore, the bundle strands are knitted in the same direction as the wire rope twist and in the opposite direction, and the cutting strands of the bundle strands and the fine bundle strands pushed into the core space of the wire rope are stored. In this case, bundle strands and fine bundle strands are knitted in a state crossing in the direction opposite to the twist direction of the wire rope to form a core space. That is, the bundle strands and fine bundle strands that are crossed in a mesh form are in a state of surrounding the periphery of the core portion gap, and the strands that are the strand cutting tip portions are sealed so that they cannot be protruded outside the wire rope. There is an effect that can be done. When tensile stress is applied during use as a wire rope sling rope, the bundle strands and fine bundle strands that are meshed and crossed shrink, i.e., the larger the tensile stress, the tighter the mesh becomes, and the gap becomes smaller. There is an effect that it can be completely sealed so that the thorn which is the tip of the strand cutting is enclosed in the core space and cannot be protruded outside the wire rope.

  According to the second aspect of the present invention, at the time of inserting the bundle strand or the fine bundle strand between the twist strands at the loop base end portion of the wire rope, the bundle is first bundled along the twist in the same direction as the twist of the wire rope. The strands are knitted by inserting the strands between the strands. This operation is performed several times, then the bundle strands are knitted along the direction opposite to the twisting of the wire rope, and then separated into inner layer wires and outer layer wires. The inner layer wire after the insertion is inserted and knitted between the twisted strands in the direction opposite to the twist of the wire rope. Therefore, the bundle strands are knitted in the same direction as the wire rope twist and in the opposite direction, and the cutting strands of the bundle strands and the fine bundle strands pushed into the core space of the wire rope are stored. In this case, bundle strands and fine bundle strands are knitted in a state crossing in the direction opposite to the twist direction of the wire rope to form a core space. That is, the bundle strands and fine bundle strands that are crossed in a mesh form are in a state of surrounding the periphery of the core portion gap, and the strands that are the strand cutting tip portions are sealed so that they cannot be protruded outside the wire rope. There is an effect that can be done. When tensile stress is applied during use as a wire rope sling rope, the bundle strands and fine bundle strands that are meshed and crossed shrink, i.e., the larger the tensile stress, the tighter the mesh becomes, and the gap becomes smaller. There is an effect that it can be completely sealed so that the thorn which is the tip of the strand cutting is enclosed in the core space and cannot be protruded outside the wire rope.

  According to the third aspect of the present invention, at the time of inserting the bundle strand or the fine bundle strand between the twisted strands at the loop base end portion of the wire rope, the bundle is first bundled along the twist in the same direction as the twist of the wire rope. The strands are knitted by inserting the strands between the strands. This operation is performed a plurality of times, and then the bundle strands are knitted along the direction opposite to the twist of the wire rope. The second fine bundle, which is divided into two sets of bundles and made into the first fine bundle and the second fine bundle, is inserted and knitted between the twisted strands in the direction opposite to the twist of the wire rope. Therefore, the bundle strands are knitted in the same direction as the wire rope twist and in the opposite direction, and the cutting strands of the bundle strands and the fine bundle strands pushed into the core space of the wire rope are stored. In this case, bundle strands and fine bundle strands are knitted in a state crossing in the direction opposite to the twist direction of the wire rope to form a core space. That is, the bundle strands and fine bundle strands that are crossed in a mesh form are in a state of surrounding the periphery of the core portion gap, and the strands that are the strand cutting tip portions are sealed so that they cannot be protruded outside the wire rope. There is an effect that can be done. When tensile stress is applied during use as a wire rope sling rope, the bundle strands and fine bundle strands that are meshed and crossed shrink, i.e., the larger the tensile stress, the tighter the mesh becomes, and the gap becomes smaller. There is an effect that it can be completely sealed so that the thorn which is the tip of the strand cutting is enclosed in the core space and cannot be protruded outside the wire rope.

  According to invention of Claim 4, the loop part of the wire rope which unfolded the free end side beforehand to the some bundle strand and was bent in loop shape is fixed, and the extension direction of this wire rope is fixed. A loop portion fixing and rotating mechanism that rotates forward and backward about the axis, a wire rope fixing mechanism that fixes a lower portion of the wire rope extending from the loop portion of the wire rope that is fixed to the forward and reverse rotation by the loop portion fixing and rotating mechanism, and a strand A needle member is inserted into the gap, and the part that should be the base end of the loop part of the wire rope is rotated by the loop part fixed rotation mechanism to partially untwist the strand and widen the gap so that it can be raised and lowered freely. It was manually inserted into the gap between the twisted strand formed by inserting the needle member with the spiking lifting mechanism and the spiking lifting mechanism Since it has a strand pulling mechanism that grips and pulls the free ends of the strands of the bundle, it can mechanically form a gap between strands for inserting spikes into the wire rope, and spiking work can be done compared to manual operation. In addition, the wire rope fixing mechanism can securely fix the lower portion of the wire rope extending from the loop portion during the insertion of the spiking. Since the bundle strand inserted in the gap between the twisted strands can be mechanically pulled by the strand tension mechanism, the strand inserted into the wire rope can be connected to the main line of the wire rope. There is an effect that it can be tightly twisted together with the twisted strand constituting the.

  According to the fifth aspect of the invention, in the loop portion fixing and rotating mechanism, in particular, the left and right clamping members are configured to be close to and away from each other, and are configured to be close to and away from each other by the operating cylinder. There is an effect that the loop portion of the rope can be gripped and the subsequent rounding operation and half-insertion operation can be easily performed.

  According to the sixth aspect of the present invention, the wire rope fixing mechanism has an effect that the wire rope can be securely fixed and the spiking insertion work and the strand wire rope insertion work can be easily performed thereafter.

  According to the seventh aspect of the present invention, since the spiking lifting mechanism is provided with a spiking cylinder having a spiking at the lower end on a base plate that can be moved back and forth, the spiking cylinder can lower the spiking. It is easy to form a gap with a diameter wire rope by spiking, and when setting the spiking position, a predetermined spiking insertion position can be set while moving the base plate back and forth, so accurate spiking difference It is possible to perform the insertion work and to facilitate the next strand insertion work.

  According to the invention described in claim 8, the strand pulling mechanism can pull the clamping device for gripping the tip end portion of the strand inserted in the main wire of the wire rope, and the clamping device in the tightening direction of the strand twist. Because the mechanism is provided, the tip of the strand can be pulled reliably and safely with a strong force, and the tightness of the twist can be strengthened to further strengthen the connection between the main end of the wire rope and the base end of the loop. There is an effect that can.

  According to the invention of claim 9, when a plurality of locking mechanisms for temporarily locking a plurality of strands whose terminal side has been released are provided, the loop base on the wire rope body side The free ends of the other strands that are not inserted between the strands of the strand are temporarily locked in the locking mechanism. In this way, other strands that are not inserted between the strands at the base end of the loop portion on the wire rope main body side interfere with the operation or move irregularly when the loop portion of the wire rope rotates. There is an effect that can prevent injury by the strand.

According to the invention described in claim 10, by using the wire rope sling rope manufacturing apparatus according to claim 4, the base end portion of the loop portion is used as a bundle strand and the strands between the strand strands of the main wire of the wire rope are twisted. After inserting and connecting in the same direction, the bundle strands are inserted in the opposite direction of twisting, and then the bundle strands of a plurality of disjointed bundles are further divided into two groups in the middle to cut one fine strand. The other narrow bundle strand is inserted into a different strand gap in the opposite direction to the twist, and the end portion of the finally cut strand is formed by extracting a part of the heart rope contained in the central portion of the wire rope. Because it is inserted and stored inside, the strand cutting part, which was conventionally called “thorn”, does not protrude from the surface of the wire rope, and the thorn is sealed in the core gap for use. And an effect can be produced safely wire rope.
In particular, since the manufacturing apparatus according to claim 4 is used, the formation of the gap for performing the strand insertion operation can be performed mechanically safely and accurately, and the strand pulling operation can also be performed mechanically reliably. There is an effect that the strength of the wire rope of the wire rope can be improved and it can be manufactured safely and reliably.

  According to the eleventh aspect of the present invention, since it is a sled-free wire rope slinging cable manufactured by the method of manufacturing a slingless wire rope sling rope, the free end of the strand is also returned into the core gap together with the core rope. Therefore, the core part is composed of a core rope and a steel wire core, and the cut part of the strand does not protrude on the surface of the wire rope, and the hollow part of the core part is buried, It has the effect of dramatically improving the steel properties and strength of the wire rope as well as safety.

V. [Narrow bundle strand forming process]
With the above, the six sets of bundle strands 1 to 6 are completely inserted into the twisted strands A to F by the respective methods of winding and cage insertion. Then, a fine bundle strand forming step is performed in which the protruding ends of the bundle strands 1 to 6 are separated into the fine bundle strands 1a to 6a of the inner layer wire and the fine bundle strands 1b to 6b of the outer layer wire. In general, a composite wire constituting a single strand is composed of inner and outer layer wires, which are referred to as inner layer wires and outer layer wires, and here, an operation of separating them into inner and outer layer wires is performed.

VI. [Inner line cutting process]
The inner layer wire fine bundle strands 1a to 6a of the six sets of bundle strands 1 to 6 are subjected to an inner layer wire cutting step of cutting at the position of the surface of the wire rope, and six sets of outer layer wires, that is, six sets of fine bundle strands 1b to 6b is left (see FIGS. 11, 15 and 16).

VII. [Inner wire tip pushing process]
The tip cutting portions of the six cut bundle strands that have been cut, that is, six so-called inner layer wire thorns, are inner layers that are pushed into the core gap 11b that is generated by removing a part of the core rope 7 at the center of the twisted strands A to F. The wire tip pushing process is performed.

VIII. [Narrow bundle strand basket insertion process]
The fine bundle strands 1b to 6b of such outer layer wires that are left protruding are subjected to a fine bundle strand insertion process that is inserted between the twisted strands A to F by the operation of the half insertion method. That is, as shown in FIG. 11, the thin bundle strands 1 b to 6 b of the first to sixth sets of outer layer wires are inserted between predetermined twisted strands A to F while being wound in a direction opposite to the twist.

(6) The sixth set of fine bundle strands 6b are inserted between the twisted strands C and D on the main wire 11a side of the wire rope 11 and pulled out between the twisted strands A and B.

  With the above, the first bundle of strands 1b to 6b of the six sets of outer layer wires is inserted into the twisted strands A to F by each method of cage insertion.

  Next, the operation | work by the 2nd time cage | basket insertion method of the 6 bundles of outer layer wire fine bundle strands 1b-6b is performed in the same procedure. This will be described in detail with reference to FIG.

(1) For example, the first bundle of thin bundle strands 1b is inserted between the twisted strands A and B on the main wire 11a side of the wire rope 11, and the space between the twisted strands E and F is removed.

(2) Insert the second set of fine bundle strands 2b from between the strand strands B and C on the main wire 11a side of the wire rope 11, and pull the space between the strands A and F through the left of the core rope 7.

  In the above-described thin bundle strand cage insertion process, the cage insertion operation in half insertion is performed twice, but the invention is not particularly limited to two times and may be twice or more.

IX. [Outer layer wire cutting step and outer layer wire tip pushing step]
When the operation | work of 2-3 times of basket insertion is complete | finished, the outer layer wire cutting process which cut | disconnects the 6 bundles of outer layer wire fine bundle strands 1b-6b protruded in the wire rope surface position is performed. The cut portion of the cut outer layer wire performs an outer layer wire tip pushing process of pushing into the core space 11b of the twisted strands A to F.

  For example, as shown in FIG. 13, two sets of each of the six bundles of outer-layer wires 1b to 6b are bundled to tap the root, and three sets of taping strand bundles are newly formed. The thin bundle strands protruding from the tip of the tape are cut and the tip portions of the three sets of taping bundle strands are inserted into the core space 11b (see FIG. 18). Then, the heart rope 7 drawn out to the outside is returned to the core space 11b. It should be noted that the six sets of outer layer wire thin bundle strands 1b to 6b described in FIG. 13 are bundled two by two and stored in the core space 11b, but the six sets of outer layer wire thin bundle strands are separated. The core gap 11b may be accommodated, or the six strands of outer layer wire bundles are bundled three by three so as to be accommodated in the core gap 11b. The strands may be bundled and stored in the core space 11b.

That is, each process consists of VI-a. Outer layer wire cutting step, VII-a. Outer layer tip pushing step, VIII-a. Fine bundle strand cage inserting step, IX-a. Inner layer wire cutting step and inner layer wire tip This is different from the indentation process.

  That is, in each of the above-described Examples VI to IX, the inner and outer layer fine bundle strands are divided in the fine bundle strand forming step, and the inner layer wire fine bundle strands 1a to 6a are cut first, and the inner layer line of the cut portion is cut. Six thorns are pushed into the core gap 11b, and then the outer strand thin strands 1b to 6b are inserted into the basket, and then cut to perform the tip pushing process. In the above embodiment, the inner layer line and the outer layer line are pushed in reversely, and the outer strands of strands 1b to 6b are cut first, pushed into the core gap 11b, and then the inner layer line is inserted into the basket. The process was performed and then cut to perform the tip pushing process.

VI-a. [Outer wire cutting process]
The outer layer wire fine bundle strands 1b to 6b of the six sets of bundle strands 1 to 6 are subjected to an outer layer wire cutting step of cutting at the position of the wire rope surface, and six sets of inner layer wires, that is, six sets of fine bundle strands 1a to 1b. Leave 6a. At this time, the core rope 7 is drawn and cut from between the twisted strands A to F, and the core gap 11b is formed at a location where a part of the core rope 7 at the center of the twisted strands A to F is removed.

VII-a. [Outer wire tip pushing process]
The six cutting ends of the six strand bundles that have been cut, so-called six outer layer wire thorns, are outer layers that are pushed into the core gap 11b generated by pulling out a part of the core rope 7 at the center of the twisted strands A to F. The wire tip pushing process is performed.

VIII-a. [Narrow bundle strand basket insertion process]
The fine bundle strands 1a to 6a of the inner layer wire that is left protruding are subjected to a fine bundle strand insertion process that is inserted between the twisted strands A to F by an operation by a half insertion method. In other words, the first-sixth to sixth-set inner-strand thin strands 1a to 6a are inserted between predetermined twisted strands A to F while being wound in a direction opposite to the twist.

(1) For example, the first bundle of strands 1a is inserted between the twisted strands D and E on the main wire 11a side of the wire rope 11, and the space between the twisted strands B and C is pulled through the left of the core rope 7.

(2) Insert the second set of fine bundle strands 2a from between the strand strands E and F on the main wire 11a side of the wire rope 11, and pull the space between the strands C and D through the right side of the core rope 7.

(6) The sixth bundle of fine bundle strands 6a is inserted between the twisted strands C and D on the main wire 11a side of the wire rope 11 and pulled out between the twisted strands A and B.

  Thus, the six strands of inner layer wire bundles 1a to 6a complete the first insertion operation into the twisted strands A to F by the respective cage insertion methods.

  Next, six sets of inner layer wire fine bundle strands 1a to 6a are subjected to a second cage operation by the same procedure.

  In the above-described thin bundle strand cage insertion process, the cage insertion operation in half insertion is performed twice, but the invention is not particularly limited to two times and may be twice or more.

IX-a. [Inner layer wire cutting step and inner layer wire tip pushing step]
When the operation | work of 2-3 times of basket insertion is complete | finished, the inner layer wire cutting process which cut | disconnects the 6 bundles of inner layer wire fine bundle strands 1a-6a which protruded in the wire rope surface position is performed. The cut part of the cut inner layer wire performs an inner layer wire tip pushing process of pushing into the core space 11b of the stranded strands A to F.

  For example, a bundle of two bundles 1a to 6a of six sets of inner layer wires is bundled to tap the root, and three sets of taping strand bundles are newly formed, and then the bundles protruding from the tip of the taping The strands are cut and the tip portions of the three sets of taping bundle strands are inserted into the core space 11b. Then, the heart rope 7 drawn out to the outside is returned to the core space 11b. It should be noted that six sets of inner layer wire thin bundle strands 1a to 6a are bundled two by two so as to be accommodated in the core space 11b. However, six sets of inner layer wire thin bundle strands are separated into the core space 11b in a disjointed state. You may make it contain. In addition, six sets of inner layer wire fine bundle strands are bundled three by three so as to be accommodated in the core space 11b. Further, six sets of inner layer wire fine bundle strands are bundled together into the core space 11b. You may make it contain.

  Through each of the above-described steps I to V and VI-a to IX-a, a wire rope sling rope without barbs is completed.

[Further other methods for manufacturing sling ropes]

Still another sling manufacturing method of the present invention is performed in the same manner from the I. bundle strand forming step to the IV. Basket insertion step in the above sling manufacturing method, and the subsequent steps are different as follows. That is, the steps are: Vb. Fine bundle strand forming step, VI-b. First fine bundle cutting step, VII-b. First fine bundle tip pushing step, and VIII-b. Fine bundle strand insertion step And IX-b. The second fine bundle cutting step and the second fine bundle tip pushing step are different.

A strand holder 149 having a V-shaped receiving groove 149a is placed on the spiking receiving plate 147a, and the main wire 11a of the wire rope 11 is placed and fixed in the receiving groove 149a in order to insert the spiking 145 into the twisted strand. It is configured to do.

  Moreover, the spiky receiver 147 is configured to run along with the spiking elevating mechanism 140 on the lower part 154 of the entire frame 102.

  That is, a sliding piece 153a is provided on the bottom surface of the substrate 153 so that the sliding piece 153a can slide on the left and right traveling rails 154.

  Therefore, the spiking elevating mechanism 140 and the spiking receptacle 147 are formed by a U-shaped frame 146 between the side surface of the spiking cylinder 143 and the side surface of the elevating cylinder 150 so that the spiking receiver 147 can move on the upper and lower traveling rails 142 and 154 at the same time. It is connected continuously.

(4) When the strand pulling mechanism 160 inserts a bundle of strands 1 to 6 formed by spiking 145 between the twisted strands A to F and draws it from the opposite side of the main line of the wire rope 11, its tip is mechanically It is configured to be pulled.

  For this purpose, the strand pulling mechanism 160 is provided at a predetermined position of the entire frame 102 so that the clamp device 170 for gripping the end portion of the strand, the wire 163 having the tip connected to the clamp device 170, and the wire 163 are stretched. A plurality of wire engaging pieces 161 and a winch portion 162 connecting the base ends of the wires 163 are configured.

  Accordingly, when the winch portion 162 is operated to wind the wire, the clamping device 170 inserts the distal end portion of the bundle of strands 1 to 6 in a predetermined direction, that is, the main wire 11a of the wire rope 11 through the pull wire 163. The bundles 1 to 6 can be pulled in the tightening direction.

  As shown in FIGS. 30 and 31, the clamp device 170 bends the wire receiver 172 provided on the machine casing 171, the presser 173 disposed above the wire receiver 172, and the upper end of the presser 173. L-shaped lever 175 pivotally supported at section 174, pivot-supporting portion 176 pivotally supporting the base end of L-shaped lever 175 to machine frame 171 and arm 177 pivotally supported at the distal end of L-shaped lever 175 The clamp device 170 is configured to be pulled in the tightening direction of the bundle strands 1 to 6 via the pull wire 163. Reference numeral 167 denotes a guide member for the arm 177. That is, the arm 177 is connected to the tip of the pulling wire that is linked to the winch portion 162, the strand tip is interposed between the wire receiving body 172 and the presser 173, and the pulling wire 163 is held by the winch portion 162. When pulling, the L-shaped lever 175 of the clamp device 170 is pivoted about the pivot 176 and presses the presser 173 against the wire receiver 172 to grip the tip of the bundle strand while clamping the clamp device. 170 is pulled in the tightening direction of the twist of the bundle strand holding the tip.

  In this manner, the bundle strands 1 to 6 inserted through the gap S formed in the main line 11a of the wire rope 11 by the operation operation of the winch portion 162 are strongly pulled in the distal direction and tightened by twisting.

  The loop portion fixing and rotating mechanism 110, the wire rope fixing mechanism 130, the spiking elevating mechanism 140, and the strand pulling mechanism 160 described above are provided at predetermined positions of the entire frame 102 that is configured in a substantially rectangular frame.

  In addition to the above-described mechanisms, the entire frame 102 temporarily fixes each bundle when the tip of the wire rope 11 bent to form the loop portion 12 is separated for each bundle of the bundle strands 1 to 6. The strand temporary fixing mechanism 180 is provided, and the strand temporary fixing mechanism 180 places a magnet metal piece having a mountain-shaped notch 181 on the bottom surface on the lateral side of the loop portion fixing rotation mechanism 110, and by magnetic force, It can be freely fixed to a metal plate disposed on the lateral side of the loop portion fixing rotation mechanism 110.

  The strand pulling mechanism 160 is connected to the winch portion 162 by pulling the base end of the arm 177 pivotally connected to the tip of the L-shaped lever 175 in the clamp member 131 to the tip of the telescopic rod of the cylinder in addition to the above configuration. An alternative to the wire 163 can be used.

  Hereinafter, a procedure for manufacturing a sled rope using a wire rope sled rope manufacturing apparatus will be described.

  First, the tip portion of the wire rope 11 is bent in a substantially U shape so as to form a sling rope on the wire rope, and is placed on the base 112 of the loop portion fixing rotation mechanism 110.

  The left and right clamping members 113 and 113 are slid in the proximity direction by the operating cylinder 114 while being clamped by the left and right clamping members 113 and 113.

  In this state, the substantially U-shaped folded portion that becomes the loop portion 12 is fixed to the pedestal 112.

  Next, the main line 11 a portion of the wire rope 11 is fixed to the entire frame 102 via the wire rope fixing mechanism 130.

  Therefore, the wire rope 11 is fixed to the entire frame 102 at the tip portion to be the loop portion 12 and the main line 11a side on the lower side.

  In such a state or before fixing the wire rope 11 on the pedestal 112, the strands constituting the tip of the wire rope 11 are untwisted in advance.

  That is, six bundle strands 1 to 6 and the heart rope 7 at the center are separated.

  Next, the spiking 145 is inserted into a position to be the base end of the loop portion of the wire rope 11 by the spiking elevating mechanism 140. If necessary, before inserting the spiky 145, the wire rope fixing mechanism 130 may be rotated in advance by rotating the main wire 11a of the wire rope 11 in the opposite direction to the twisting to loosen the twisting.

  That is, the spiking 145 suspended from the spiking cylinder 143 of the spiking lifting mechanism 140 is inserted into the main line 11 a of the wire rope 11 by the lowering operation of the spiking cylinder 143. Spike 145 is inserted between adjacent strands A to F.

  Thus, the spiky 145 is skewered between the stranded strands A to F on the main line 11 a side of the wire rope 11.

  Next, the pedestal 112 is rotated by the loop portion fixing and rotating mechanism 110 while the spiky 145 is skewed.

  When the pedestal 112 is rotated in the direction in which the twists of the twisted strands A to F are returned, in the portion where the tip side of the spiky 145 of the needle member penetrates, the loop base that is located on the side where the twist is returned with the spiking 145 penetrated The twisted strands A to F rotate and move, but the twisted strands A to F located on the opposite side of the side where the twist is returned are prevented from rotating by the tip side of the spiking 145 that penetrates. For this reason, the gap S gradually begins to spread between the twisted strands A to F that rotate and move to the side where the twist is returned and the spiking 145 that has penetrated, and the gap that allows the bundle strand 1 to be inserted around the spiking 145 that has penetrated. S is formed.

  When a sufficient gap S is secured between the twisted strands C to D around the spiky 145, the rotation of the base 112 is stopped.

  The worker inserts the bundle strand 1 through the gap S between the strands C and D formed in the periphery through which the spike 145 passes (see FIG. 33). Since the gap S is sufficiently wide, it is possible to prevent the strands from coming into contact with each other and being damaged when inserted. After inserting and passing through the gap S, the front end side of the strand 1 is sandwiched and fixed to the front end side of the strand pulling mechanism 160 provided on one side of the loop portion fixing rotation mechanism 110.

  By driving the winch portion 162, the clamp device 170 holding the tip end side of the bundle strand 1 is pulled and moved, whereby the bundle strand 1 inserted through the gap S between the twisted strands C and D is pulled. The mechanism 160 is pulled up by the operation. Compared to the case where the operator pulls up and tightens as in the prior art, the pulling-up force by the strand pulling mechanism 160 is constant, so the quality is constant.

  Further, in accordance with the operation of the strand pulling mechanism 160, the motor 118 is rotated in the reverse direction, and the pedestal 112 is rotated in the reverse direction.

  Since the twisted strands A to F rotate in the twisting direction, the widened gap S is closed.

  Further, the spiky 145 whose tip side has penetrated the wire rope has a loop portion base of the wire rope along the twisted strands A to F that are twisted in a spiral shape as the twisted strands A to F rotate in the twisting direction. It moves to an end side direction, and moves to the place away from the place where the bundle strand 1 was inserted (refer FIG. 34).

  Thus, the strand 1 rotates in the twist direction, and the spiky 145 that has penetrated moves, so that the portion into which the strand 1 is inserted is tightened back.

  In the case where the bundle strands 1 to 6 are inserted in the direction opposite to the twist of the wire rope, the spiky 145 that has penetrated is once pulled out from the twist strands A to F, and then again between the twist strands A to F. The same operation is repeated thereafter.

  In another way, the strands 1 to F are twisted while the bundle strand 1 is inserted again around the spiky that has penetrated, and the strand strand mechanism 160 pulls and tightens the bundle strand 1. Rotate in the direction to return the twist and repeat this several times. In this way, a wire rope slinging line (see FIG. 35) having no thorns in which a ring-shaped loop portion 12 is formed on the end side is manufactured.

  Moreover, during the operation, the ends of the six bundle strands 1 to 6 are manually separated into the inner layer wires 1a to 6a and the outer layer wires 1b to 6b, and the ends of the inner layer wires 1a to 6a are cut, and the wire rope 11 is pushed into the core gap 11b, and the thin bundle strands of the outer layer wires 1b to 6b are also inserted between the twisted strands A to F, and then the tip is cut and pushed into the core gap 11b. In this work, the work of inserting the spiking 145 between the twisted strands A to F of the wire rope 11 is performed by the spiking lift mechanism 140 and the work of expanding the gap between the twisted strands A to F is the loop portion fixing and rotating mechanism 110. To do. The operation of pushing the cutting tip into the core space 11b is performed by the spiking elevating mechanism 140 and the loop portion fixing and rotating mechanism 110. That is, the spiking mechanism 145 is inserted between the strands A to F of the wire rope 11 by the spiking lifting mechanism 140, and the spiking insertion portion is expanded by the rotation of the loop portion fixing and rotating mechanism 110. Is manually pushed into the core gap 11b.

  In addition, the slinging rope manufacturing apparatus of this wire rope can be applied also to slinging of synthetic fiber ropes other than metal. In this case, the spiky shape is changed for use.

Insert and store in the formed core gap, and then insert the other set of non-cut bundle strands into the gaps between the different strands so that they are in the opposite direction to the twisting direction of the wire rope. After the operation of inserting the non-cut fine bundle strands is completed several times, the free ends of the non-cut fine bundle strands are finally cut, and the spiky formed strand gaps are used. 5. The cutting portion is inserted and stored in a core space formed by removing a part of a heart rope containing a central portion of the wire rope so as not to protrude from the peripheral surface of the wire rope. A method for manufacturing a wire rope with no thorns using the above apparatus.   A slingless wire rope sled rope manufactured by the method for manufacturing a sledless wire rope sled rope according to any one of claims 1 to 3.
