Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for laying a bird damage prevention wire in a high-voltage power transmission line facility, and more specifically, operating an operating rod to safely secure the bird damage prevention wire to a transmission line tower or the like. Regarding the method for laying.

[0002]

2. Description of the Related Art When birds fly into a high voltage transmission line facility such as a power transmission line tower, they are electrocuted, which causes power transmission troubles. Stretching is done. Since it is dangerous to stretch the wire on the live line, conventionally, after stopping the power transmission, the worker moves to the tip of the arm part of the tower and manually stretches the wire. I was doing.

[0003]

However, in the conventional means, the power transmission must be temporarily stopped when the wire is stretched, and the worker must move to the tip of the arm portion where the high voltage power transmission line is wired. It had to be moved, which was a dangerous and tedious task. Therefore, it is an object of the present invention to provide a method for easily laying a bird damage prevention wire on a live wire.

[0004]

To this end, according to the present invention, the grasping tool 5 at the tip of one operation rod 1 is provided with the bird damage prevention wire 1.
The support 11 to which one end of the support 3 is attached is grasped, and the fixture 15 attached to the lower end of the support 11 is attached to the angle member 53.
And the attachment 24 of the driver 22 mounted on the tip of the other operating rod 21.
Is fitted to the bolt 16 attached to the
Is driven so that the bolt 16 is screwed in.

[0005]

According to the above structure, one operator operates one operation rod 1 and the other operator operates the other operation rod 21 to cause the arm portion 53 of the transmission line tower to The wire 13 can be easily stretched.

[0006]

Embodiments of the present invention will now be described with reference to the drawings. FIG. 1 is a plan view during the wire tensioning work,
In the arm portion 51 of the transmission line tower, two workers
By operating the electrically insulating operation rods 1 and 21, the bird damage prevention wire is stretched. 52 is an insulator.

FIG. 2 is a perspective view of an essential part during the above work.
A gripping tool 5 is attached to the tip of one of the operating rods 1 via an angle adjusting tool 2, a universal joint 3, and a connecting tool 4. The universal joint 3 and the connector 4 are connected by a bolt 6 (see also FIG. 4). Further, a projection 7 is inserted into the connecting tool 4, and the projection 7 projects into the holding tool 5. A spring member 8 is interposed between the bolt 6 and the protrusion 7, and the spring force pushes the protrusion 7 forward. By changing the screwing depth of this bolt 6,
The spring force of the spring material 8 can be adjusted.

The gripping tool 5 has a substantially U-shape, and a column 11 is gripped between the plate 9 fixed to the tip of the protrusion 7 and the front wall portion 5a of the gripping tool 5. (See also Figure 5). As shown in FIG. 6, holes 12 are formed in the support column 11 at a pitch, and the wires 1 are inserted into the holes 12.
A stopper 1 to which a stopper 14 to which 3 is attached is attached.
By selecting the hole 12 to which the wire 4 is attached, the wire 1
The tension height of 3 can be adjusted. The wire 3 is made of fishing line or the like, and the wire 13 is stretched to prevent birds from flying to a dangerous place.

An attachment 15 is connected to the lower end of the column 11, and the attachment 15 is attached to the angle member 53 of the arm 51 with a bolt 16.

In FIG. 3, a driver 22 is attached to the tip of the other operating rod 21. The driver 22 has a main body 23 having a built-in motor and an attachment 24 that is driven by the motor to rotate.

As shown in FIG.
The wires 25 and 26 of the book extend to the proximal end side of the operating rod 21, and when one wire 25 is pulled, the motor rotates in the forward direction, and when the other wire 26 is pulled, the motor rotates in the reverse direction.
27 is a mounting body.

In FIG. 3, at the base end of the operating rod 21,
A reel 28 is mounted, and the other ends of the wires 25 and 26 are wound around the reel 28. Operating rod 21
Is a short tube 21a, 21b, 21c having different diameters that is extendably connected, and shortened when not needed. In that case, the wires 25, 26 are wound around the reel 28.

Next, a method of tensioning the wire 13 will be described. As shown in FIG. 1, a worker climbs up to the arm portion 51, one worker holds the one operation rod 1, and as shown in FIG. Charge into. The other operator holds the other operation rod 21, fits the attachment 24 to the bolt 16, and then pulls the wire 25. Then, the motor is driven, the bolt 16 is screwed in, and the fixture 15 is fixed to the angle member 53.

In this way, the fixture 15 is attached to the angle member 5
3 is fixed to 3, the gripping tool 5 is forcibly removed from the column 11, and the other end of the wire 13 is attached to the arm portion 51.
The wire 13 is stretched by attaching the wire 13 at an appropriate position on the base end side. As described above, according to the present means, it is possible to easily wire 1 in the high danger area such as the arm 51 of the transmission line tower.
3 can be stretched.

[0015]

As described above, according to the present invention, one operator operates one operating rod 1 and the other operator operates the other operating rod 21 to transmit a transmission line tower. The wire 13 can be easily stretched on the arm portion 53 or the like.
