Description

  The present invention relates to a method of preventing the sagging of a wire.

  Copper wires may break due to stress corrosion or the like. A broken wire that hangs down causes a human injury such as an electric shock accident by falling to the ground. Therefore, conventionally, there has been a method of using a rope to prevent drooping of the electric wire (see, for example, Patent Document 1).

  In this technique, between a plurality of electric wires arranged in parallel, adjacent electric wires and wires are connected by ropes. The ropes are provided at a plurality of places at predetermined intervals in the middle of the electric wire along the extending direction. As a result, even if a break occurs, the broken wire can be prevented from hanging down to the ground because it is supported by the wire adjacent to the rope.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings, but the arrangement relationship of each component is only schematically shown to the extent that the present invention can be understood. Also, although preferred embodiments of the present invention will be described below, numerical conditions and the like are merely preferred embodiments. Therefore, the present invention is not limited to the following embodiments, and many changes or modifications that can achieve the effects of the present invention can be made without departing from the scope of the configuration of the present invention.

(How to prevent the cable from hanging down)
With reference to FIG. 1, a method of preventing the drooping of the electric wire according to the embodiment of the present invention (hereinafter, also simply referred to as a drooping preventing method) will be described. FIG. 1 is a schematic view for explaining a method of preventing drooping.

  In the example of FIG. 1, three electric wires 105 are installed across the utility poles 101 and 103.

  In the sagging prevention method according to this embodiment, the wire 110 is wound around each wire 105.

  The wire 110 is wound around the wire 105 helically along the extension direction of the wire 105 and around the wire 105 as an axis. Also, the wire 110 is wound around the electric wire 105 across the utility poles 101 and 103. Both ends of the wire 110 are fixed to the electric wire 105 using a connecting member 115 such as a C-shaped connector, for example.

  The wire 110 is made of a material having high insulating properties and high tensile strength, such as polyester monofilament. As the wire 110, for example, a chain coil (registered trademark) manufactured by Toray Industries, Inc. can be used.

  In the sagging prevention method according to this embodiment, the wire 110 can be wound around the wire 105, for example, by the following process. That is, first, the wire 110 (for example, the above-described chain coil) formed in a coil shape is wound around the end of the electric wire 105 on the side of one of the power poles 101. Next, the wire 110 is stretched to the other power pole 103 side. As a result, the drawn wire 110 is wound around the electric wire 105 across the utility poles 101 and 103.

  In the sagging prevention method according to this embodiment, even when the wire 105 is broken, the wire 105 is supported by the wound wire 110, so that the wire 105 can be prevented from hanging down.

  Further, in the method of preventing sagging according to this embodiment, it is possible to prevent the wires 105 from hanging down by winding the wires 110 around each of the wires 105 one by one. For this reason, as compared with the conventional method in which a large number of ropes are attached between the wires, it is possible to prevent the sagging of the wires efficiently. Then, by using a wire winding device and a pilot wire pulling device described later, the wire can be wound around the electric wire 105 across the utility poles 101 and 103 efficiently by a simple operation.

(Wire winding device)
With reference to FIG. 2, a wire winding apparatus (hereinafter, also simply referred to as a wire winding apparatus) according to an embodiment of the present invention will be described. FIG. 2 is a schematic view showing a wire winding device.

  The wire winding device 100 is a device used when attaching the wire 110 to the wire 105.

  The wire winding device 100 is configured to include the operation unit 10, the indirect unit 20, the joint unit 30, and the wire holding unit 40 connected in this order.

  The operation unit 10 includes an operation unit 12 provided on the main body 11 and a side surface of the main body 11.

  The main body 11 is a hollow, for example, cylindrical body. Inside the main body portion 11, a rotation mechanism 13 is provided along the extending direction of the main body portion 11. The rotation mechanism 13 is provided so as to extend from the inside of the main body 11 to the inside of the indirect part 20 described later.

  The operation means 12 is, for example, a rotary handle or the like. The operation unit 12 is connected to the rotation mechanism 13 inside the main body 11 by, for example, a unit that transmits the rotation of a gear or the like. And by operating the operation means 12, the rotation mechanism 13 inside the main-body part 11 rotates centering around the central line along the extension direction of the said rotation mechanism 13 as an axis. Here, the rotation mechanism 13 is rotated by rotating the handle as the operation means 12.

  The indirect part 20 is a hollow, for example, cylindrical body. Moreover, the indirect part 20 is comprised with the insulating material. The indirect part 20 is connected with the main-body part 11 of the operation part 10 continuously, making the extending direction correspond. The rotation mechanism 13 described above is accommodated in the inside of the indirect part 20 along the extension direction of the indirect part 20.

  Further, the distance between the operation unit 10 and the joint unit 30 is determined in accordance with the length along the extension direction of the indirect unit 20. Therefore, by appropriately setting the length along the extension direction of the indirect portion 20, the distance between the operation portion 10 and the joint portion 30 can be adjusted to a length corresponding to the height of the wire 105. it can.

  The joint portion 30 is configured as a universal joint (universal joint) in which the first connection portion 31 and the second connection portion 32 are connected. The joint portion 30 will be described with reference to FIG. FIGS. 3A and 3B are schematic views showing the joint portion 30. FIG. In FIG. 3A, the first connection portion 31 and the second connection portion 32 are shown as being transparent.

  The first connection portion 31 is provided on the operation portion 10 side, and is connected to the indirect portion 20. The second connection portion 32 is provided on the side of a wire holding portion 40 described later, and is connected to the rotating portion 41 of the wire holding portion 40. The first connection portion 31 and the second connection portion 32 include a coupling portion 33 in which the tip portions of the first connection portion 31 and the second connection portion 32 overlap with each other. In the coupling portion 33, a rotation shaft 34 orthogonal to the extending direction of the main body portion 11 and the indirect portion 20 of the operation portion 10 is provided to penetrate the first connection portion 31 and the second connection portion 32. The first connection portion 31 and the second connection portion 32 are rotatable around the rotation shaft 34, respectively. Therefore, by rotating the first connection portion 31 and the second connection portion 32, the angle between the first connection portion 31 and the second connection portion 32 can be changed. Note that in FIG. 3 (A), the joint portion 30 when the angle between the first connection portion 31 and the second connection portion 32 is at a right angle, and in FIG. 3 (B), the first connection portion 31 and the second connection portion 32 The joint part 30 in case the angle between 2 connection parts 32 is 180 degrees is shown, respectively.

  The joint unit 30 is provided with three bevel gears (a first bevel gear 35, a second bevel gear 36, and a third bevel gear 37).

  The first bevel gear 35 is provided at the first connection portion 31. The first bevel gear 35 is connected such that the rotation mechanism 13 and the center line along the extension direction of the rotation mechanism 13 coincide with each other. Therefore, the first bevel gear 35 rotates about the central line along the extending direction of the rotation mechanism 13 in conjunction with the rotation of the rotation mechanism 13.

  The second bevel gear 36 is provided at the coupling portion 33. The second bevel gear 36 rotates about a center line along the rotation axis 34.

  The third bevel gear 37 is provided at the second connection portion 32. The third bevel gear 37 is connected such that a rotating portion 41 of a wire holding portion 40 described later and a center line along the extending direction of the rotating portion 41 coincide with each other. Then, the third bevel gear 37 rotates about a central line along the extending direction of the rotating portion 41.

  The first bevel gear 35 and the third bevel gear 37 respectively engage with the second bevel gear 36. Therefore, the second bevel gear 36 and the third bevel gear 37 rotate in conjunction with the rotation of the first bevel gear 35. Therefore, when the rotation mechanism 13 connected to the first bevel gear 35 rotates, the rotating portion 41 of the wire holding portion 40 connected to the third bevel gear 37 rotates in an interlocking manner.

  In addition, a suspension hook 38 is provided at the first connection portion 31 of the joint portion 30. The hanging hook 38 is provided on the extension along the extension direction of the above-mentioned indirect part 20. The hanging hook 38 is formed in a hook shape and can be hung on a wire.

  The wire holding portion 40 includes a rotating portion 41 and a hanging hook 42 provided at one end (the end opposite to the joint portion 30) of the rotating portion 41.

  The rotating portion 41 is, for example, a cylindrical body. The wire 110 is attached to the rotating unit 41. As the wire 110, one formed into a coil shape (for example, the above-described chain coil or the like) is used. The wire holding portion 40 can hold the wire 110 by inserting the rotating portion 41 into the air hole (air hole defined in the wire 110) 110a formed by forming the wire 110 into a coil shape. In addition, the rotation part 41 can hold | maintain the wire 110 reliably by using rubber | gum, resin, etc. with large frictional force with respect to the wire 110 as a member of the rotation part 41. FIG.

  The rotating portion 41 rotates in conjunction with the third bevel gear 37 of the joint portion 30 about a central line along the extending direction of the rotating portion 41.

  The hanging hook 42 is configured to include, for example, one or more hooks and can be hung on a wire. Here, as an example, the suspension hook 42 is configured to include two hooks 42 a and 42 b.

  Here, FIGS. 4A and 4B are schematic views showing the end of the wire holding portion 40 on the side of the hanging hook 42 in an enlarged manner. The hanging hook 42 can be pivoted about a connection point with the rotating portion 41 as an axis. Thus, the hanging hook 42 is in a first state (FIG. 4A) upright in a direction perpendicular to the extending direction of the rotating portion 41 and a second state (figure in FIG. 4) along the extending direction of the rotating portion 41. You can take 4 (B). In the first state, the hooks 42 a and 42 b of the hanging hook 42 are disposed in a plane perpendicular to the extending direction of the rotating portion 41. Further, in the second state, the hook-like portions 42 a and 42 b of the hanging hook 42 are disposed in the extension direction of the rotating portion 41 in the extending direction.

  The hanging hook 42 is connected to the rotating portion 41 so as to be rotatable independently of the rotating portion 41 with the rotation axis along the extending direction of the rotating portion 41 as an axis. For this reason, the rotation of the rotating portion 41 and the rotation of the suspension hook 42 are not interlocked. Therefore, even if the rotating portion 41 rotates in a state in which the hanging hook 42 is hooked and fixed to the electric wire, the hanging hook 42 can maintain the positionally fixed state without rotating.

  In addition, although the case where the hanging hook 42 included two collar-like parts 42a and 42b was demonstrated here, the structure of the hanging hook 42 is not limited to this. As long as the hanging hook 42 can be hung on the electric wire 105, for example, the hanging hook 42 can be configured by only one hook-like portion.

  In the wire winding device 100, the rotation mechanism 13 is rotated by operating the operation means 12 of the operation unit 10. As the rotation mechanism 13 rotates, the first bevel gear 35, the second bevel gear 36 and the third bevel gear 37 of the joint portion 30, and the rotating portion 41 of the wire holding portion 40 rotate.

  Also, as described above, the wire winding device 100 can be attached to the electric wire by hooking the hanging hook 42 of the wire holding portion 40 to the electric wire. Then, in the state where the wire winding device 100 is attached to the electric wire, the rotating hook 41 of the wire holding portion 40 and the electric wire are extended by rotating the hanging hook 42 about the connection portion with the rotating portion 41 as an axis. It can be made to approach while matching the direction. In this state, by rotating the rotating portion 41, the wire 110 held by the rotating portion 41 can be wound around the electric wire, and the wire 110 can be wound around the electric wire.

  Further, in the wire winding device 100, as described above, by setting the length of the indirect portion 20 appropriately, the distance between the operation portion 10 and the joint portion 30 according to the height of the electric wire to which the wire 110 is attached. Can be adjusted. Therefore, for example, when winding the wire 110 around electric wires of various heights, the rotation unit 41 can be rotated by operating the operation unit 10 in, for example, a bucket of a work platform.

  Furthermore, as described above, the indirect part 20 is made of an insulating material. Therefore, when hanging the hanging hook 42 of the wire holding part 40 on an electric wire, winding the wire 110 on an electric wire, etc., the operation part 10 connected with the indirect part 20 can be handled by hand.

(Pilot wire pulling equipment)
With reference to FIG. 5, a pilot wire traction device (hereinafter, also simply referred to as a pilot wire traction device) according to an embodiment of the present invention will be described. FIG. 5 is a schematic view showing a pilot wire pulling tool.

  The pilot wire pulling tool 200 is a tool used in stretching a pilot wire connecting the wire 110 and the utility pole.

  The pilot wire pulling tool 200 is configured to include the operation unit 50, the indirect unit 60, the guide unit 70, and the roller unit 80 connected in this order.

  The operation unit 50 includes a main body 51 and a holder 52.

  As the main body 51, for example, a commercially available drill driver can be used. Therefore, hereinafter, the main body 51 is also referred to as a drill driver 51. The drill driver 51 is rechargeable and includes a rotating member 53, a trigger 54, and a motor (not shown).

  The rotating member 53 is provided to extend in the direction of the indirect portion 60. The drill driver 51 drives the motor by pulling the trigger 54. Then, by the drive of the motor, the rotating member 53 is rotated about a central line along the extending direction of the rotating member 53.

  The holder 52 accommodates the main body 51. The holder 52 includes an operating means (here, a toggle switch) 55 and a knurled screw 56.

  The toggle switch 55 is connected to the trigger 54. Then, by switching ON / OFF of the toggle switch 55, it is possible to switch the pulled or released state of the trigger 54. Therefore, by operating the toggle switch 55, the rotating member 53 of the drill driver 51 can be rotated. Further, by adjusting the knurled screw 56, it is possible to adjust the degree to which the trigger 54 is pulled when the toggle switch 55 is in the ON state. Therefore, by adjusting the knurled screw 56, the rotational speed of the rotating member 53 can be adjusted.

  Furthermore, a rotation mechanism 57 is connected to the rotation member 53. The rotation mechanism 57 is provided so as to extend in the direction toward the roller portion 80 across the inside of the indirect portion 60 and the main body portion 75 of the guide portion 70. The rotation mechanism 57 rotates about the central line along the extension direction of the rotation mechanism 57 as the rotation member 53 rotates.

  The indirect portion 60 is a hollow, for example, cylindrical body made of an insulating material. The rotation mechanism 57 described above is accommodated in the inside of the indirect part 60 along the extension direction of the indirect part 60.

  Further, the distance between the operation unit 50 and the guide unit 70 is determined according to the length along the extension direction of the indirect unit 60. Therefore, the distance between the operation unit 50 and the guide unit 70 can be adjusted to a length corresponding to the height of the electric wire 105 by appropriately setting the length along the extension direction of the indirect portion 60. it can.

  The guide 70 includes a main body 75 which is a hollow cylindrical body, for example, and a guide 71 connected to the main body 75. The guide 71 is provided to project in a direction orthogonal to the extending direction of the main body 75. Further, the guide 71 is disposed to face the roller 84 of the roller unit 80 described later.

  The guide 71 can rotate around the main body 75 around a center line along the extension direction of the main body 75. By this rotation, the guide 71 can be moved from the position facing the roller 84 of the roller unit 80 to the non-facing position. Further, a bearing 72 is provided at an end of the guide 71 on the roller portion 80 side.

  Furthermore, the guide 71 can change the position in the vertical direction (the direction along the extension direction of the main body 75). Therefore, by changing the position of the guide 71, the distance between the roller unit 80 and the guide 71 can be changed. As a result, the distance between the roller 84 of the roller unit 80 and the guide 71 of the guide unit 70 can be changed.

  Further, a pilot wire connecting portion 73 is provided in the guide portion 70. The pilot wire connection portion 73 is a frame-like body, and is provided projecting from the side surface of the main body portion 75. Here, the pilot wire connection portion 73 is provided on the lower portion (the side of the indirect portion 60) of the guide 71. When using the pilot wire traction device 200, connecting the pilot wire traction device 200 and the pilot wire by fixing the pilot wire through a hole defined in the pilot wire connection 73 it can.

  The portion where the pilot wire connection portion 73 is provided is not limited to the guide portion 70. Depending on the design, it may be provided on the operation unit 50, the indirect unit 60 or the roller unit 80. Also, the pilot wire connection portion 73 may have a function of connecting the pilot wire to the pilot wire pulling tool 200, and is not limited to the frame-like body.

  The roller unit 80 includes a first gear 81, a second gear 82, a connecting shaft 83, and a roller 84.

  The first gear 81 and the second gear 82 are, for example, flat gears.

  The roller 84 is formed of, for example, a disk-like body having a pair of opposing main surfaces (a front surface 84a and a back surface 84b).

  The first gear 81 is connected to the rotation mechanism 57 described above. The first gear 81 can rotate around a rotation mechanism 57 as an axis along a plane orthogonal to the extending direction of the rotation mechanism 57.

  The second gear 82 and the roller 84 are provided to face each other along a plane parallel to the extending direction of the rotation mechanism 57. The connecting shaft 83 is fixedly connected to the second gear 82 and the roller 84 while penetrating the centers of the second gear 82 and the roller 84 in the planar direction. The second gear 82 and the roller 84 can be interlocked and rotated along a plane parallel to the extending direction of the rotation mechanism 57, with the connecting shaft 83 connecting them as a rotation axis.

  The second gear 82 is engaged with the first gear 81. Therefore, the second gear 82 rotates in conjunction with the rotation of the first gear 81. As described above, the second gear 82 and the roller 84 are connected by the connecting shaft 83. Accordingly, the roller 84 rotates in conjunction with the rotation of the second gear 82.

  Here, on the side surface 84c connecting the front surface 84a and the back surface 84b of the roller 84, a groove-shaped concave portion 85 is provided along the rotation direction of the roller 84 over the entire circumference. When using the pilot wire pulling tool 200, the electric wire 105 is engaged with the recess 85 of the roller 84 by aligning the rotation direction of the roller 84 with the extension direction of the electric wire 105. The cross-sectional shape of the recess 85, the angle of the inner wall surface, and the like can be designed under conditions suitable for the roller 84 gripping the electric wire 105 in accordance with the thickness of the electric wire 105 and the like. Further, by affixing, for example, sand paper to the inner wall surface of the recess 85, the coefficient of friction between the inner wall surface of the recess 85 and the electric wire 105 can be increased. As a result, when the roller 84 rotates, the pilot wire pulling tool 200 can be reliably made to self-run along the electric wire 105. The sandpaper is attached to the inner wall surface of the recess 85 in a detachable manner, for example, by a surface fastener or the like. Thus, sandpaper can be replaced if it becomes clogged.

  Further, as another configuration example of increasing the coefficient of friction between the inner wall surface of the recess 85 of the roller 84 and the electric wire 105, a plurality of holes can be formed in the inner wall surface of the recess 85. In this case, the electric wire 105 is caught on the edge of the hole, so that the coefficient of friction between the inner wall surface of the recess 85 and the electric wire 105 is increased.

  When using the pilot wire traction tool 200, the guide 71 is disposed at a position facing the roller 84. Then, while the electric wire 105 is engaged with the concave portion 85 of the roller 84, the position of the guide 71 is moved upward (roller portion 80 side) to bring the roller 84 and the guide 71 close to each other. Thus, the electric wire 105 is sandwiched by the roller 84 and the guide 71 in the vertical direction, and is defined by the recess 85 of the roller 84 and the guide 71. As a result, the pilot wire pulling tool 200 can be attached to the wire 105 while preventing the roller 84 from coming off the wire 105.

  Then, in a state where the pilot wire pulling tool 200 is attached to the electric wire 105, the toggle switch 55 of the operation unit 50 is operated to rotate the rotating member 53 of the drill driver 51. When the rotating member 53 rotates, the rotating mechanism 57 and the first gear 81, the second gear 82, the connecting shaft 83, and the roller 84 of the roller unit 80 rotate in an interlocking manner. As a result, the pilot wire pulling tool 200 is self-propelled along the extending direction of the electric wire 105 in a state of being attached to the electric wire 105.

  As described above, the bearing 72 is provided at the end of the guide 71 on the roller portion 80 side. Therefore, the lower side of the wire 105 contacts the bearing 72 in a state where the wire 105 is defined by the recess 85 of the roller 84 and the guide 71. As a result, the resistance of the wire 105 in contact with the guide 71 is reduced, so that the pilot wire pulling tool 200 can be made to travel smoothly.

  Also, when removing the pilot wire traction tool 200 from the electric wire 105 after using the pilot wire traction tool 200, the roller 84 and the guide 71 are moved by moving the position of the guide 71 downward (the side of the indirect portion 60). Let them separate. Furthermore, the guide 71 is moved to a position not facing the roller 84. Thus, the wire 105 can be easily removed from the roller 84 through the gap between the roller 84 and the guide 71.

  Further, in the pilot wire pulling apparatus 200, as described above, by appropriately setting the length of the indirect part 60, the distance between the operation part 50 and the guide part 70 is set according to the height of the electric wire to which the wire 110 is attached. The distance can be adjusted. For this reason, for electric wires of various heights, for example, work such as attachment of the pilot wire pulling tool 200 and operation of the operation unit 50 for causing the pilot wire pulling tool 200 to self-propelled, for example, a high work vehicle Can be done from the bucket.

  Furthermore, as described above, the indirect part 60 is made of an insulating material. Thus, for example, the pilot wire traction tool 200 can be handled by hand in operations such as attaching the pilot wire traction tool 200 to a wire and operating the operation unit 50 for causing the pilot wire traction tool 200 to self-propelled.

  The reel 301 is configured to include a pair of flat bodies 311 and 312 provided so as to face each other, and a core 313 connecting the flat bodies 311 and 312. The reel 301 can rotate with the core portion 313 as a rotation axis. Also, the core portion 313 is used as a winding shaft of the pilot wire. By rotating the reel 301 in a state in which the pilot wire is wound around the core portion 313, the pilot wire can be drawn out or taken up.

  The lever 302 and the thumbscrew 303 are both connected to the reel 301. The reel 301 can be rotated by turning the lever 302 or the thumbscrew 303. The lever 302 can be turned manually. Further, as shown in FIG. 6 (B), the thumb screw 303 can be turned using, for example, an electric drill driver 350.

  Furthermore, the winding device 300 is provided with a connection portion 304 for a rope. The connection portion 304 is configured, for example, as a frame. The winding device 300 can be fixed to the utility pole by connecting, for example, a back rope tied to the utility pole to the connection portion 304.

  Next, the pulley will be described. FIG. 7A is a schematic view of the pulley as viewed from the front. FIG. 7 (B) is a schematic view of the pulley shown in FIG. 7 (A) as viewed from the left side of the drawing.

  The pulley 400 comprises a clamp 401 and a sheave 404.

  The clamp 401 is configured to include an upper jaw 402 and a lower jaw 403 provided opposite to each other. The lower jaw 403 can move relative to the upper jaw 402 in an approaching or separating direction. Thereby, the upper jaw 402 and the lower jaw 403 can sandwich the electric wire 105 in the vertical direction. As a result, the pulley 400 can be attached to the wire 105.

  The sheave 404 is a disk-like body, and can be rotated in the direction along the wire 105 about the center of the disk-like body in a state where the clamp 401 sandwiches the wire 105. The side surface of the sheave 404 is recessed like a groove, along which the pilot wire can be hung. The pull direction of the pilot wire can be changed by fixing the pulley 400 to the electric wire 105 and hooking the pilot wire connecting the wire and the utility pole to the sheave 404.

  The pulley 400 can be attached to or removed from the electric wire 105 on the ground by connecting it with an indirect hot-wire tool (not shown) having a length corresponding to the height of the electric wire 105. As an indirect hot-wire tool, what is comprised with an insulating material and has a rotating shaft can be used. Then, the pulley 400 is attached to the electric wire 105 by moving the lower jaw 403 of the clamp 401 closer to or away from the upper jaw 402 by rotating the rotary shaft of the indirect hot-wire tool by an operation on the ground. Can be removed from

(Wire winding method)
A wire winding method (hereinafter, also simply referred to as a wire winding method) according to an embodiment of the present invention will be described with reference to FIGS. 8 to 14 are schematic diagrams for explaining the wire winding method.

  First, the wire winding apparatus 100 (see FIG. 2) described above is prepared. Then, the wire holding unit 40 is caused to hold the wire 110 by inserting the rotating unit 41 of the wire holding unit 40 into the coiled wire 110. Annular ring terminals are attached to both ends of the wire 110, respectively. Moreover, the wire 110 is adjusted to the length according to the distance between the utility poles 101 and 103 by processing such as cutting in advance. In addition, the hanging hooks 42 of the wire holding portion 40 are erected in the direction orthogonal to the extending direction of the rotating portion 41. Furthermore, the first connection portion 31 and the second connection portion 32 of the joint portion 30 are arranged to be orthogonal to each other (that is, the angle between the first connection portion 31 and the second connection portion 32 is orthogonal). In this state, the wire winding device 100 is lifted upward. At this time, the rotary unit 41 is supported by the indirect hot-wire tool 130 having a length corresponding to the height of the electric wire 105, and the indirect hot-wire tool 130 and the operation unit 10 or the indirect unit 20 of the wire winding device 100 are lifted together. The rotating portion 41 and the electric wire 105 are brought close to each other (see FIG. 8).

  Then, the hanging hook 42 of the wire holding portion 40 is hooked on the wire 105 at one end (here, the end on the side of the utility pole 101) of the wire 105 installed between the utility poles 101 and 103. Next, the angle between the first connection portion 31 and the second connection portion 32 of the joint portion 30 is adjusted, and the suspension hook 38 of the joint portion 30 is hung on the electric wire 105 (see FIG. 9). As a result, the wire winding device 100 can be attached to the electric wire 105 in a state in which the rotating portion 41 and the electric wire 105 are in close proximity to each other with the extension directions thereof being matched.

  Next, the rotation mechanism 13 is rotated by operating the operation means 12 of the operation unit 10. In conjunction with the rotation of the rotation mechanism 13, the first bevel gear 35, the second bevel gear 36 and the third bevel gear 37 of the joint portion 30, and the rotating portion 41 of the wire holding portion 40 rotate. Then, when the rotating portion 41 rotates, one end of the wire 110 (here, the end on the power pole 101 side) is hooked on the electric wire 105, and the wire 110 held around the rotating portion 41 is wound on the electric wire 105. (See FIG. 10). As a result, the wire 110 is spirally wound around the end of the electric wire 105 along the extension direction of the electric wire 105 and around the electric wire 105 as an axis.

  Next, after all the wire 110 is wound around the end of the electric wire 105 on the electric pole 101 side, one end of the wire 110 (here, the end on the electric pole 101 side) is temporarily fixed to the electric wire 105 (see FIG. 11).

  For temporary fixing of the wire 110 and the electric wire 105, for example, a clamp 501 to which the protrusion 502 is attached can be used. That is, the wire 110 can be temporarily fixed to the wire 105 by fixing the clamp 501 to the wire 105 and hooking the ring terminal (not shown) attached to one end of the wire 110 to the projection 502.

  Next, the pilot wire pulling tool 200 and the winder 300 (see FIGS. 5 and 6) described above are prepared. The pilot wire 120 is wound around the reel 301 of the winder 300. The winder 300 is fixed to the utility pole by connecting a back hand rope 503 connected to the utility pole 105 to the connection portion 304 of the winder 300.

  Also, the pilot wire pulling tool 200 is attached to the other end of the electric wire 105 (here, the end on the power pole 103 side). Then, the pilot wire pulling tool 200 and one end of the pilot wire 120 (the end on the outer peripheral side of the pilot wire 120 wound around the reel 301) are connected using the pilot wire connection portion 73 (see FIG. 5) of the indirect portion 60 Do. Thus, one end of the pilot wire 120 is connected to the pilot wire pulling tool 200 and the other end is connected to the utility pole 105 via the winder 300 (see FIG. 12).

  Thereafter, the operation unit 50 of the pilot wire pulling tool 200 is operated (the toggle switch 55 is turned on), whereby the roller 84 of the roller unit 80 is rotated. Thereby, the pilot wire pulling tool 200 travels along the electric wire 105 toward the utility pole 101 side. The self-propelled pilot wire traction tool 200 causes the pilot wire 120 connected to the pilot wire traction tool 200 to be pulled toward the utility pole 101 while being unwound from the reel 301 of the winder 300.

  Next, by operating the operation unit 50 of the pilot wire pulling tool 200 that has reached the end of the electric wire 105 on the power pole 101 side (turning the toggle switch 55 off), the free running of the pilot wire pulling tool 200 is stopped. . One end of the pilot wire 120 reaches the end of the electric wire 105 on the power pole 101 side together with the pilot wire pulling tool 200. Then, one end of the pilot wire 120 connected to the pilot wire pulling tool 200 is removed from the pilot wire pulling tool 200. Also, the pilot wire pulling tool 200 is removed from the wire 105. Furthermore, one end of the pilot wire 120 is connected to the other end of the wire 110 opposite to the temporarily fixed end (here, the end on the utility pole 103 side). For example, the pilot wire 120 and the wire 110 can be connected by fixing the ring terminal attached to the other end of the wire 110 through one end of the pilot wire 120. As a result, the wire 110 and the utility pole 103 are connected by the pilot wire 120.

  Moreover, the pulley 400 (refer FIG. 7) mentioned above is attached to the electric wire 105 in power pole 103 vicinity. Then, the pilot wire 120 is hung on the sheave 404 of the pulley 400. The pulley 400 can be operated, for example, from a bucket of a work platform by connecting with an indirect hot-wire tool (not shown) (see FIG. 13).

  Thereafter, by rotating the reel 302 of the winder 300, the pilot wire 120 is wound up. This pulls the pilot wire 120 in the direction towards the utility pole 103. When starting winding of the pilot wire 120, since the tension by the wire 110 is small, the reel 301 is rotated by turning the thumb screw 303 using a drill driver. Then, after the tension by the wire 110 is increased (for example, after about 500 N or more), the reel 301 is rotated by operating the lever 302 manually.

  By winding up the pilot wire 120, the wire 110 connected to the pilot wire 120 is stretched toward the utility pole 103 side. After the other end of the wire 110 on the electric pole 103 side reaches the end of the electric wire 105 on the electric pole 103 side, both ends of the wire 110 are fixed to the electric wire 105 using a connecting member 115 such as a C-type connector. Then, the connection between the wire 110 and the pilot wire 120 is disconnected.

  As a result, the wire 110 is wound around the wire 105 helically along the extension direction of the wire 105 and around the wire 105 as an axis. In addition, the wire 110 is wound around the wire 105 across the utility poles 101 and 103 (see FIG. 14).

  As described above, in the wire winding method using the wire winding device 100 and the pilot wire pulling device 200, the worker works on the utility pole 101 and the operation of winding the wire 110 around the electric wire 105 and delivering and winding the pilot wire 120. The work may be performed in the vicinity of 103, and the wire 110 can be easily wound around the wire 105.
