And a total of 7 people. The other power transmission lines 2B and 1B are also transferred in the same manner. Next, as shown in FIG. 14, a method of transferring a transmission line from the arm of the existing steel tower 71 to the respective arms of the new steel tower 81 by bypassing the transmission line at the top of the existing steel tower 71 will be described.

First, the top gold wheel 1 is attached to the top of the existing steel tower 71, and the arm tip gold wheel 41 is passed through the tips of the arms 73, 74, and 75,
A transfer roller 61 is attached to the tip of the pulling wire 76, and the transfer roller 61 holds the power transmission line 1A. The base end side of the pulling wire 76 is connected to the winch 79 through the arm 83 with the gold wheel 78 interposed.

On the other hand, the sending wire 86 is connected to the winch 90 with the gold wheels 77 and 78 interposed on the way to the transfer roller 61. The worker 91 operates the winch 79 to wind up the pulling wire 76, and the worker 92 operates the winch 90 to send out the sending wire 86. Then, the transfer roller
The power transmission line 1A held by 61 reaches the top rail car 1 at the top of the existing steel tower 71 and immediately passes therethrough to reach the tip of the arm 83. arm
The workers 93 and 94 on 83 remove the power transmission line 1A from the transfer roller 61 and attach it to the tip of the arm 83. The guide wire 99 guides the power transmission line 1A. The arrangement position of the power transmission line 1A is indicated by 1A '.

There are a total of 7 workers in this transfer method.
The other power transmission lines 2A and 3A are also transferred in the same manner. Further, although the above-mentioned embodiment describes the example in which the new steel tower is right next to the existing steel tower, the present invention can be applied not only when the new steel tower is right next to it but also when it is diagonally installed.

22 and 23 are plan views showing a case where the new steel tower is installed diagonally to the side of the existing steel tower. The distance between the existing steel tower 71 and the existing steel tower 71 is approximately 350 m.
The parallel travel distance from the existing steel tower 71 is up to approximately 15 m. The power transmission line 1A attached to the existing steel tower 71 of the relocation source is detached from the arm tip and held by the transfer roller 61, and the transfer roller 61 has a sending wire 86 and a pulling wire.
76 is provided, a guide wire 99 is stretched at the arm tip, and the transmission wire 1A is sent out by the wire 86 while being pulled.
Move the power transmission line 1A while pulling at 76 and being tense,
Dodge the arm tip wagon 41 and the top wagon 1, and transfer to the destination of the new steel tower 81.

Since the power transmission line 1A is stretched and stretched between the supporting portion at the arm tip and the existing steel tower 71, only the transfer source is normally removed, and the transmission line 1 is provided on both sides of the transfer source.
Transfer the wire with A fixed. When the length of the transfer destination is insufficient when the wire is transferred, the power transmission line 1A is not cut at the wire transfer source and is cut at any one of both sides of the wire transfer source.
Cut and add to secure the length.

In the diagram of FIG. 22, the upper transmission line 1A is connected to a new steel tower 81.
14 corresponds to FIG. 14, and the perspective view of the lower transmission line 1A in FIG. 22 corresponds to FIG. 13 for the new steel tower 81. FIG. 23 shows an example in which the lower transmission line 1A in the figure is transferred to the lower side in the figure of the new steel tower 81. The state is changed to a sequential state and the line is transferred. At this time, the tension angle of the power transmission line 1A gradually changes.
Therefore, the power transmission line 1A must be movable in the transfer roller 61. The power transmission line 1A must be movable in the transfer roller 61.
The transfer roller 61 holds the power transmission line 1A. Transfer roller 61 is sending wire 86
The power transmission line 1A is tensioned by the pulling wire 76 and the power transmission line 1A is transferred.

In the above embodiment, an example of transferring the transmission line from the existing steel tower to the new steel tower has been described, but the same applies to the case of transferring the existing steel tower to the temporary steel tower and from the temporary steel tower to the new steel tower. The same applies to the case of a temporary iron pillar instead of a temporary steel tower.

[0059]

As described above, according to the present invention, the transmission line stretched between the arms of the existing steel tower is installed on the side of the new steel tower located on the side of the existing steel tower, or from the existing steel tower to the side of the temporary steel tower or the temporary steel tower. This is a method of transferring a transmission line to transfer the transmission line to the new steel tower side.The top gold wheel is placed at the top of the steel tower, the arm tip wagon is placed at the arm end, and the top gold wheel and the arm tip are placed. A guide wire that guides the power transmission line is stretched between the gold wheel and the transfer wire is attached to a part of the power transmission line to be transferred, and the pulling wire and the sending wire are connected to this transfer roller. After that, while pulling out the sending wire from the transfer source steel tower side, pull up the pulling wire at the transfer destination steel tower side,
In pulling up the power transmission line to be transferred from the transfer source steel tower side to the transfer destination steel tower side, guiding the pulling operation of the pulling wire, the sending wire and the transfer roller by the top gold wheel and arm tip gold wheel, Since it was configured to guide the dodging action of the power transmission line to be transferred that passes through the top of the steel tower with the top gold wheel and the arm tip wagon, it is possible to transfer without disconnecting the power line, and a protective scaffold becomes unnecessary, There is no need to secure vast land. In addition, the work of dodging the transmission line at the top of the steel tower can be eliminated, the number of workers can be significantly reduced, the work time can be shortened, and a safe and efficient transmission line transfer method can be provided.

Further, according to the present invention, the transmission line stretched between the arms of the existing steel tower is installed on the side of the new steel tower located on the side of the existing steel tower, from the existing steel tower to the temporary steel tower side, or from the temporary steel tower to the new steel tower side. Derailment to prevent the transmission line from being disconnected in the transfer tool of the top metal wheel to be installed on the top of the tower used for guiding the power line when transferring the power line, and the arm tip metal wheel to be installed at the end of the arm Since it is a transfer tool equipped with a prevention roller and a guide wire roller that stretches a guide wire that guides the power transmission line, it prevents the power transmission line from falling off and smoothly moves the power transmission line downward. Can be made.

Furthermore, the present invention is for a transfer line used in a transfer line construction method for transferring a transmission line stretched between the arms of an existing steel tower to the side of a new steel tower located on the side of the existing steel tower. Horizontal rollers and vertical rollers that guide the power transmission line at both ends of the frame, some of the horizontal rollers can be opened and closed so that they can be attached to the power transmission line, and a pulling wire and a feeding wire are sent to the center of the frame. Since it is a transfer roller used for the transfer method of the transmission line that is connected to the wire, it is not necessary to dodge the transmission line with the top wagon and the arm tip wagon of the steel tower. And the arm tip can be passed.
