Play a role in preventing

  FIG. 7 is a schematic explanatory view of a method of passing a cable through the bundled hanger 105 wound in a spiral shape or the like around the support wire 103 by using the wiring tool 1 shown in FIG.

  Next, the detachable tool 4 that detachably couples the operation rod 3 and the main body will be described with reference to FIGS.

  8 is an overall side view of the detachable tool 4 shown in FIG. 1, FIG. 9 is an overall sectional view of the detachable tool 4 shown in FIG. 8, and FIG. 10 is an XX ′ line in FIG. 11 is a side view of the upper part 4a of the detachable tool 4 shown in FIG. 8, and FIG. 12 is a side view of the lower part 4b of the detachable tool 4 shown in FIG.

  As shown in FIGS. 8 to 12, the detachable tool 4 is composed of an upper part 4a and a lower part 4b having a circular cross section that are detachably connected to each other, and an upper end 4a1 of the upper part 4a is formed by a first screw 4a3. The lower end 4b1 of the lower part 4b is fixed to the tip 3d of the operating rod 3 by a second screw 4b3.

  The upper part 4a of the detachable tool 4 further includes an upper part 4a5 and a lower part 4a7. The upper part 4a5 and the lower part 4a7 are fixed by a third screw 4a9, and the upper part 4a5 and the lower part 4a7 are fixed. The cylindrical lower portion 4a7 forms an insertion portion 4a10 into which the lower part 4b of the detachable tool 4 is inserted.

  The lower end of the upper part 4a5 is provided with a first magnet 4a11 corresponding to a second magnet 4b5 of a lower part 4b described later, and a lower part of the lower part 4a7 engages with a protrusion 4b7 of the lower part 4b described later. A groove 4a13 is provided.

  Here, as shown in FIG. 10, the groove 4a13 is provided at four locations around the insertion portion 4a10. This is for facilitating engagement with a protrusion 4b7 of the lower part 4b described later. That is, the protrusion 4b7 of the lower part 4b only needs to engage with any of the grooves 4a13 provided at the four locations, and therefore, the effort to rotate and adjust the operating rod 3 so that the protrusion 4b7 fits the groove 4a13. And the engagement between the groove 4a13 and the protrusion 4b7 is facilitated.

  In this embodiment, the number of the grooves 4a13 is four, but may be three, two, or one.

  The lower part 4b of the detachable tool 4 has a circular cross section, the upper part has a diameter to be inserted into the insertion part 4a10 of the upper part 4a, and the lower part has a diameter larger than the upper part diameter, A second magnet 4b5 corresponding to the first magnet 4a11 is provided at the upper end of the upper part, and a protrusion 4b7 that engages with the groove 4a13 is provided at the joint part between the upper part and the lower part.

  The insertion part 4a10 of the upper part 4a is separated from the first magnet 4a11 and the second magnet 4b5 by a predetermined distance L in a state where the upper part of the lower part 4b has been inserted.

  As a result, a smooth attaching / detaching operation can be achieved during the attaching / detaching operation between the operation rod 3 and the main body, as will be described later.

  In this embodiment, the first magnet 4a11 and the second magnet 4b5 are separated by a predetermined distance L in a state where the upper part of the lower part 4b has been inserted into the insertion part 4a10 of the upper part 4a. However, in order to secure a stronger magnetic force, the first magnet 4a11 and the second magnet 4b5 are in contact with each other in a state where the upper part of the lower part 4b has been inserted into the insertion part 4a10 of the upper part 4a. It may be designed to do.

  Further, the protrusion 4b7 of the lower part 4b is engaged with one of the four grooves 4a13 of the upper part 4a, so that the rotation operation of the operation rod 3 with respect to the main body is restricted as will be described later. Therefore, the cable wiring operation using the wiring tool 1 can be performed accurately.

  Next, the usage method of the wiring tool 1 of the structure mentioned above is demonstrated.

  13 and 7 are schematic descriptions of a method of passing a cable or a tow string through the bundled hanger 105 wound in a spiral shape or the like around the support wire 103 using the wire tool 1 shown in FIG. FIG.

  First, the operator 13 attaches the lower end of the holding part 5 of the main body part to the tip of the operation rod 3 via the detachable tool 4.

  Then, the front guide member 107 is attached to the one end 7d of the traction portion 7, and a new cable 10 (or a string to which the new cable 10 is connected) is attached to the locking member of the other end 7e of the traction portion 7. Then, as shown in FIG. 13, the telescopic operation rod 3 is extended to bring the main body of the wire passing tool 1 closer to the bundled hanger 105, and from one end of the bundled hanger 105 to one end 7 d of the towing unit 7. The front guide member 107 attached to the hanger 105 is inserted into the bundled hanger 105.

  At this time, the operating rod 3 is in a state perpendicular to the longitudinal direction of the front guide member 107 by about 45 °, but the protrusion 5 c provided on the holding portion 5 is the holding member at the base end portion of the front guide member 107. It is prevented from being pinched between 5a and 5b.

  When the front guide member 107 is inserted into the bundled hanger 105, the operator 13 operates the operation rod 3 so that the wire passing tool 1 is directed in the direction A shown in FIG.

  At this time, as shown in FIG. 7, the leading guide member 107 and the wire passing tool 1 are moved in the A direction in a state in which the operation rod 3 is tilted backward by about 45 ° with respect to the longitudinal direction of the leading guide member 107. The operating rod 3 is operated.

  Thereby, as shown in FIG. 13, the lower part 105 a of the bundled hanger 105 enters the entrance 15 between the holding part 5 and the pulling part 7 of the wire passing tool 1.

  At this time, since the protrusion 4b7 of the lower part 4b is engaged with the groove 4a13 of the upper part 4a of the detachable tool 4, the rotation operation of the operating rod 3 with respect to the main body is restricted. Therefore, the advancing direction of the line tool 1 can be reliably maintained, and the cable line operation using the line tool 1 can be performed accurately.

  Here, each columnar member 9 c of the rotary member 9 is temporarily anchored at a predetermined position by the magnet member 11. That is, here, the predetermined position of the rotary member 9 is a position at which the columnar member 9c stops so that the entrance 15 between the holding portion 5 and the traction portion 7 opens widely.

  Thereby, the lower part 105a of the bundled hanger 105 can enter the entrance 15 smoothly.

  If there is no function of temporarily anchoring each columnar member 9c of the rotary member 9, each columnar member 9c stays at the entrance 15, and the lower portion 105a of the bundled hanger 105 smoothly enters the entrance 15. You may not be able to enter.

  Next, when the wiring tool 1 is operated to move in the direction of arrow A, the lower part 105a of the bundled hanger 105 hits the columnar member 9c1 near the entrance 15, and the columnar member 9c1 is attached in the direction of arrow B. The columnar member 9c3 attracted by the magnet member 11 is pulled away from the pulling force of the magnet member 11, the rotary member 9 is rotated in the direction of arrow B, and the next columnar member 9c1 is attracted by the magnet member 11.

  In addition, simultaneously with the rotation of the rotary member 9 in the arrow B direction, the wheel 9f of each columnar member 9c moves in the arc-shaped groove 7c of the traction portion 7.

  In this way, the columnar member 9c of the rotary member 9 is always at the stop position (predetermined position) where the entrance 15 between the holding portion 5 and the traction portion 7 is widely opened. 105 a smoothly enters the entrance 15, and is held between the columnar members 9 c of the rotary part 9 in accordance with the rotation of the rotary member 9 in the direction of arrow B. You can go out from the exit 17 between the two.

  As a result, the front guide member 107 and the traction portion 7 advance in the bundled hanger 105 in the direction of the arrow A, and a new cable attached to the locking member 7f of the traction portion 7 or for traction A string 10 or the like is passed through the bundled hanger 105.

  Note that when the front guide member 107 and the pulling portion 7 advance in the bundled hanger 105 in the direction of arrow A, the scraping fins 7f are connected to the drop cable 101 in the bundled hanger 105 as shown in FIG. By scraping, the drop cable 101 is prevented from being caught in the groove 7 c of the pulling portion 7 of the wire passing tool 1.

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

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

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

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

  Here, when installing a new cable such as an optical cable along the communication line that is the main line of the electric pole installed on the utility 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, it may be necessary to cross the other communication line.

  In such a case, as shown in FIG. 14, the operator 13 moves the line tool 1 until the other communication line 101 </ b> E contacts the operation bar 3 of the line tool 1, and moves the operation bar 3. By pulling in the direction F, the upper part 4a and the lower part 4b of the detachable tool 4 that are detachably connected to each other are separated, and only the operation bar 3 of the wire-line tool 1 is under the other 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 protrusion 4b7 of the lower part 4b may be engaged with one of the grooves 4a13 provided at four locations. The effort to rotate and adjust the operating rod 3 so that the protrusion 4b7 fits the groove 4a13 is reduced, and the engagement between the groove 4a13 and the protrusion 4b7 can be easily performed.

  By doing so, the operation rod 3 of the line tool does not come into contact with the other communication line 101E, and the line operation cannot be performed, and a continuous line operation can be achieved.

  FIG. 14 is a schematic explanatory diagram of the line operation when another communication line 101E is laid under the communication line 101 performing the line operation.

  In addition, when installing a new cable such as an optical cable along the communication line that is the main line of the electric pole installed on the utility pole, the communication line crosses the road in the movement operation of the wiring tool along the communication line. Even when the line work has to be interrupted due to circumstances, the line work can be easily interrupted by the attaching / detaching operation of the upper part 4a and the lower part 4b of the detachable tool 4.

  In addition, in the attaching / detaching 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 to 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, the operator 13 applies a predetermined pulling force to the operation rod 3 when the upper part 4a and the lower part 4b are separated. 4a and lower part 4b can be pulled apart.

  That is, the attraction ability of the first magnet 4a11 and the second magnet 4b5 and the first magnet 4a11 and the second magnet so that the upper part 4a and the lower part 4b of the detachable tool 4 are attracted by a predetermined attraction force. A distance L between 4b5 is set.

  Thereby, the operator 13 can perform the separation 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 bundled hanger 105 and the like. In the state where the insertion has been completed in the upper part of the lower part 4b of the insertion part 4a10 of 4a, the upper part 4a and the lower part of the detachable tool 4 are undesirably placed by an attractive force of the first magnet 4a11 and the second magnet 4b5. The operation rod 3 is not detached due to the separation from 4b.

  Further, in this embodiment, the conventional tip guide member 107 as shown in FIG. 20 is attached to the wiring tool 1, but the present invention is not limited to this, and the tip of another structure such as a rod is used. A guide member may be attached or nothing may be attached.

  As described above, according to the wiring tool 1 embodying the present invention, the cable 101 installed along the communication line serving as the main line of the electric wire installed on the utility pole is wound around the support line 103 in a spiral shape or the like. There is an effect that the new cable 10 can be passed through the bundled hanger 105 easily, safely and smoothly while being bundled by the bundled hanger 105 and supported by the support wire 103.

  Next, with reference to FIG. 15 and FIG. 16, the line tool 1 of the 2nd Embodiment of this invention is demonstrated.

  That is, as shown in FIG. 11, the front guide member 107 is suspended between the center rod 107c having the distal end portion 107a and the proximal end portion 107b, and the rear portion of the distal end portion 107a and the front portion of the proximal end portion 107b. The suspension bar 107d has a plurality of (in this case, two) suspension rods 107d, and the suspension rod 107d has a shape in which the central portion swells in the outer peripheral direction of the center rod 107c.

  And the outer periphery cover 107e becomes a structure which has a hole in the front-end | tip and a rear end. Then, as shown in FIG. 15, the outer peripheral cover 107e goes from the rear end hole through the front end portion 107a of the center bar 107c, and as shown in FIG. 12, the outer peripheral cover so as to completely cover the outer periphery of the suspension bar 107d. 107e is attached to the front guide member 107.

  When the outer peripheral cover 107e is attached to the front guide member 107 in this way, for example, parts such as the terminal end of the bundled hanger 105 enter the front guide member 107 and hinder the movement of the front guide member 107. There is no.

  Next, with reference to FIG. 17 and FIG. 18, the line tool 1 of the 3rd Embodiment of this invention is demonstrated.

  The wiring tool 1 according to the third embodiment is provided with a magnet 5d on the protruding portion 5c of the holding portion 5 and a magnet 5d on the proximal end portion 107b of the front guide member 107 at a position corresponding to the magnet 5d. The metal part 107f which contacts is provided.

  With such a configuration, when the operator lifts the line tool 1 to insert the front guide member 107 into the bundled hanger 105 from one end of the bundled hanger 105, the magnet 5d and Since the metal part 107f is adsorbed, the operation of the front guide member 107 is stabilized.

  That is, when the operator operates the operating rod 3 and lifts the wiring tool 1, the new cable 10 attached to the locking member 23 of the stabilizing rod 21 is also lifted, but the weight of the new cable 10 is increased. The pulling portion 7 is rotated in the direction of arrow B around the shaft portion 9a of the rotary member 9, and accordingly, the tip of the front guide member 107 attached to the pulling portion 7 is lifted upward, It became unstable by shaking up and down, making it difficult to insert the front guide member 107 into the bundled hanger 105.

  Therefore, if the magnet 5d of the holding portion 5 and the metal portion 107f of the front guide member 107 are attracted as in the third embodiment, the operator operates the operation rod 3 to connect the wire tool. Since the operation of the front guide member 107 is stabilized when lifting 1, the front guide member 107 can be easily inserted into the bundled hanger 105.

  In addition, after the front guide member 107 is inserted into the bundled hanger 105, the operation rod 3 is operated backward to easily separate the magnet 5d of the holding portion 5 and the metal portion 107f of the front guide member 107. Therefore, the front guide member 107 and the pulling portion 7 can be advanced into the bundled hanger 105 in the direction of arrow A.

  The present invention is not limited to the embodiment of the invention described above, and can be implemented in other modes by making appropriate modifications.
