  At the same time as the rotary member 9 rotates in the direction of the arrow B, the wheels 9f of the columnar members 9c move in the arc-shaped grooves 7c of the traction portion 7.

  As described above, the columnar member 9c of the rotary member 9 is always at the stop position (predetermined position) where the entrance 15 between the holding unit 5 and the traction unit 7 is greatly opened. 105a enters the entrance 15 smoothly, and is held between the columnar members 9c of the rotary portion 9 with the rotation of the rotary member 9 in the direction of arrow B, and the holding portion 5 and the traction portion 7 From the exit 17 between the two.

  As a result, the forward guide member 107 and the towing portion 7 advance in the direction of arrow A in the united hanger 105, and a new cable or tow attached to the locking member 7f of the towing portion 7 is obtained. The string 10 is passed through the bundle hanger 105.

  When the leading guide member 107 and the pulling unit 7 travel in the direction of the arrow A in the bundle hanger 105, the squeezing fins 7f move the drop cable 101 in the bundle hanger 105 as shown in FIG. This prevents the drop cable 101 from being caught in the groove 7 c of the pulling portion 7 of the wire passing tool 1.

  Then, by carrying the leading guide member 107 and the pulling portion 7 out of the bundled hanger 105 from the other end of the bundled hanger 105, a new cable is connected from one end of the bundled hanger 105 to the other end. 10 will pass.

  As described above, a new cable or towed string 10 is passed through the bundled hanger 105, so that it is not necessary to use the straight rod 109 as shown in the conventional example of FIG. A new cable or towed string 10 can be directly attached to the locking member 21 of 7, and the labor of the operator can be greatly reduced.

  In addition, the rotary member 9 can be rotated not only in the direction of arrow B but also in the direction of arrow C opposite to the direction of arrow B.

  Therefore, even when the new cable 10 is passed too much in the direction A shown in FIG. 7 (into the single hanger 105), the wire passing tool 1 can be returned in the direction D, and a new cable 10 is desired. It is also possible to pass back to the position.

  Further, when a new cable such as an optical cable is installed along a communication line serving as a main line of an electric wire installed on a telephone pole, the wiring tool 1 must be moved along the communication line. Another communication line is laid under the line, and when performing the line operation, there is a case where it is necessary to cross the other communication line. In such a case, the operating rod 3 hits another communication line, and the line operation cannot be continued as it is.

  That is, the other communication lines may become obstacles and hinder the line operation.

  In such a case, as shown in FIG. 19, the operator 13 moves the passing tool 1 until the other communication line 101E contacts the operating rod 3 of the passing tool 1, and moves the operating rod 3 By pulling in the direction F, the upper part 4a and the lower part 4b of the detachable tool 4, which are removably connected to each other, are separated from each other, and only the operating rod 3 of the wiring tool 1 goes under another communication line 101E. After the movement, the upper part 4a and the lower part 4b of the detachable tool 4 are connected again.

  When the upper part 4a and the lower part 4b of the detachable tool 4 are connected again, the projection 4b7 of the lower part 4b may be engaged with any of the grooves 4a13 provided at four places. The labor for rotating and adjusting the operation rod 3 so that the projection 4b7 fits into the groove 4a13 is reduced, and the engagement between the groove 4a13 and the projection 4b7 can be easily performed.

  By doing so, the continuous operation can be achieved without the operation bar 3 of the operation tool 3 coming into contact with the other communication line 101E to disable the operation.

  FIG. 19 is a schematic explanatory diagram of the communication operation when another communication line 101E is laid below the communication line 101 performing the communication operation.

  In the embodiment illustrated in FIG. 19, another communication line 101 </ b> E is illustrated as an obstacle, but a tree branch, a utility pole lamp, and the like also become obstacles.

  In addition, when a new cable such as an optical cable is installed along a communication line that is a main line of an electric wire installed on a telephone pole, the communication line crosses a road in a movement operation of a wiring tool along the communication line. Even if the wiring work must be interrupted due to circumstances or the like, the wiring work can be easily interrupted by the attachment / detachment operation of the upper part 4a and the lower part 4b of the detachable tool 4.

  In addition, at the time of the attachment / detachment operation of the upper part 4a and the lower part 4b of the detachable tool 4 described above, the first magnet 4a11 and the second magnet 4b5 move the upper part of the lower part 4b of the insertion part 4a9 of the upper part 4a. When the upper part 4a and the lower part 4b are separated from each other, the worker 13 applies a predetermined pulling force to the operating rod 3 when the upper part 4a and the lower part 4b are separated from each other. 4a and the lower part 4b can be separated.

  That is, the attraction capability of the first magnet 4a11 and the second magnet 4b5 and the first magnet 4a11 and the second magnet 4a11 so that the upper part 4a and the lower part 4b of the detachable tool 4 attract each other with a predetermined attraction force. 4b5 is set.

  Thus, the worker 13 can perform the detaching operation of the upper part 4a and the lower part 4b of the detachable tool 4 with a predetermined pulling force that does not adversely affect the bundle hanger 105 and the like. In a state where the upper part 4a of the detachable tool 4 has been inserted into the upper part of the lower part 4b of the insertion part 4a10 at an undesired place by the attraction force of the first magnet 4a11 and the second magnet 4b5. There is no possibility that the operating rod 3 is detached by being separated from the operating rod 4b.

  Further, there are cases where it is difficult to pass below the communication line for moving the tool through the operation rod 3 with the operation rod 3 such as a road or a river with heavy traffic.

  In such a case, a wire connection operation is performed as described below.

  FIG. 20 to FIG. 22 are schematic explanatory diagrams of a method of towing the tow rope 6 in the line operation by the line tool 1.

  As shown in FIG. 20, in the example of the fourth method of towing the tow rope 6, in a state where the upper part 4a and the lower part 4b of the detachable tool 4 are separated from each other, the worker 12 connects in the A direction. The pulling rope 6 is pulled in the direction E so that the tool 1 is directed.

  According to the example of the fourth towing method, since the towing operation of the towing rope 6 by the operator 12 is performed, the line tool 1 is moved in a state where the upper part 4a and the lower part 4b of the detachable tool 4 are separated. Is more smoothly performed in the direction A.

  In other words, the line tool 1 can be moved in the direction A without operating the operation rod 3 without the operation rod 3, so that the line operation can be easily performed even in a place where the operation rod 3 is difficult to pass. I can do it.

  As shown in FIG. 21, in the fifth example of the towing method of the tow rope 6, when the upper part 4 a and the lower part 4 b of the detachable tool 4 are separated from each other, the worker 12 connects in the A direction. The pulling rope 6 is pulled in the F direction via the wheel 8 provided on the support line 103 so that the tool 1 is directed.

  According to the example of the fifth towing method, since the worker 12 performs the towing operation of the towing rope 6 using the wheel 8 provided on the support line 103, the traveling tool 1 is moved in the A direction. The pulling force becomes stronger, and the movement of the wire passing tool 1 in the direction A is performed more smoothly.

  In other words, the line tool 1 can be moved in the direction A without operating the operation rod 3 without the operation rod 3, so that the line operation can be easily performed even in a place where the operation rod 3 is difficult to pass. I can do it.

  As shown in FIG. 22, in the sixth example of the method of towing the tow rope 6, in a state where the upper part 4 a and the lower part 4 b of the detachable tool 4 are separated from each other, the worker 13 passes through the line in the direction A. The pulling rope 6 is pulled in the G direction via the wheel 8 provided on the support line 103 so that the tool 1 is directed.

  According to the example of the sixth towing method, since the towing operation of the towing rope 6 is performed by the worker 13 using the wheel 8 provided on the support line 103, the passing tool 1 in the direction A is pulled. The pulling force becomes stronger, and the movement of the wire passing tool 1 in the direction A is performed more smoothly.

  In other words, the line tool 1 can be moved in the direction A without operating the operation rod 3 without the operation rod 3, so that the line operation can be easily performed even in a place where the operation rod 3 is difficult to pass. I can do it.

  Here, in the fifth towing method shown in FIG. 21 and the sixth towing method shown in FIG. 22, the installation position of the gold wheel 8 is the support line 103, but as described below, But it is good.

  FIG. 18 is a schematic explanatory view showing a modification of the installation position of the gold wheel 8.

  As shown in FIG. 18, the wheel 8 may be installed on an installation protrusion 111 a provided on the utility pole 111, in addition to the support wire 103, or may be provided on another support bridge laid over the upper part 111 b of the utility pole 111. You may make it install in the line 111c. In addition, as the installation projection 111a, a projection for climbing a worker, a part of an electric lamp, or the like may be used.

  Further, in this embodiment, a conventional forward guide member 107 as shown in FIG. 28 is attached to the wire passing tool 1. However, the present invention is not limited to this. A guide member may be attached or nothing may be attached.

  As described above, according to the wire passing tool 1 embodying the present invention, the cable 101 installed along the communication line, which is the main wire of the electric wire, is wound around the support wire 103 in a spiral shape or the like. In a state where the cables are bundled by the bundle hanger 105 and supported by the support wires 103, an effect is obtained that a new cable 10 can be easily, safely, and smoothly passed through the bundle hanger 105.

  Next, with reference to FIGS. 23 and 24, a description will be given of a wire passing tool 1 according to a second embodiment of the present invention.

  The wire passing tool 1 according to the second embodiment has a configuration in which an outer peripheral cover 107e that covers the outer periphery of the forward guide member 107 is attached to the forward guide member 107.

  That is, as shown in FIG. 23, the forward guide member 107 is suspended between the center rod 107c having the distal end 107a and the proximal end 107b, and the rear of the distal end 107a and the front of the proximal end 107b. The suspension rod 107d has a structure having a plurality (three in this case) of suspension rods 107d, and the suspension rod 107d has a shape in which the center portion expands in the outer peripheral direction of the center rod 107c.

  The outer peripheral cover 107e has a configuration in which a hole is formed at the front end and the rear end. Then, as shown in FIG. 23, the distal end 107a of the center rod 107c passes through the hole at the rear end of the outer peripheral cover 107e, and as shown in FIG. 24, the outer peripheral cover 107e covers the outer periphery of the suspension rod 107d completely. Is attached to the front guide member 107.

  When the outer peripheral cover 107e is attached to the front guide member 107 in this manner, for example, a component such as the end portion of the bundled hanger 105 enters the inside of the front guide member 107, and hinders the movement of the front guide member 107. There is no.

  Next, with reference to FIGS. 25 and 26, a description will be given of a wire passing tool 1 according to a third embodiment of the present invention.

  In the wire passing tool 1 according to the third embodiment, a magnet 5d is provided on a protruding portion 5c of a holding portion 5, and a magnet 5d is provided on a base end portion 107b of a forward guide member 107 at a position corresponding to the magnet 5d. The configuration is such that a contacting metal part 107f is provided.

  By adopting such a configuration, when the operator lifts the wire passing tool 1 in order to insert the leading guide member 107 from one end of the bundled hanger 105 into the bundled hanger 105, the worker can move the magnet 5 d with the magnet 5 d. Since the metal portion 107f is attracted, the operation of the guide member 107 is stabilized.

  That is, when the operator operates the operating rod 3 and lifts the wire passing tool 1, the new cable 10 attached to the locking member 23 of the stabilizer bar 21 is also lifted, but the weight of the new cable 10 is increased. , The towing portion 7 rotates around the shaft portion 9 a of the rotary member 9 in the direction of arrow B, and accordingly, the tip of the forward guide member 107 attached to the towing portion 7 is lifted up, The guide member 107 swings up and down and becomes unstable, making it difficult to insert the guide member 107 into the bundle hanger 105.

  Therefore, as in the third embodiment, if the magnet 5d of the holding portion 5 and the metal portion 107f of the forward guide member 107 are attracted, the operator operates the operation rod 3 to pass through the wire passing tool. Since the operation of the front guide member 107 is stabilized when the first guide member 107 is lifted, the front guide member 107 can be easily inserted into the bundled hanger 105.

  After the guide member 107 is inserted into the bundle hanger 105, the operating rod 3 is operated backward to easily separate the magnet 5d of the holding portion 5 from the metal portion 107f of the guide member 107. Therefore, the guide member 107 and the traction portion 7 can be advanced in the direction of the arrow A into the single hanger 105.
