（産業上の利用分野）
本発明は、送電線の低張力延線工法に関するものである
。DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a low-tension stretching method for power transmission lines.
（従来の技術）
従来の送電線架線工法として、鉄塔に金車を取り付け、
この金車に線条を通過させて延線する工法が行われてい
るが、鉄塔と鉄塔の間ではその延線する線条が大きく垂
れ下がるので、それを防ぐ゛目的で高張力で延線する。(Conventional technology) As a conventional power transmission line overhead line construction method, a metal wheel is attached to a steel tower.
This construction method is used to extend the wire by passing the wire through the metal wheel, but since the wire being extended hangs significantly between the steel towers, the wire is extended with high tension to prevent this. .
この工法は、所謂高張力延線工法と言われている。This construction method is called the so-called high-tension wire extension construction method.
この高張力延線工法を実施する場合に、送電線鉄塔の間

意が必要で、高い張力で線条を張設して下の物体に接触
しないようにして延線しなければならない。When implementing this high-tension line construction method, when the spacing between transmission line towers, that is, the span is long, the wires are thick (sagging) between the towers, so in urban areas, old lines, If there are buildings or cultivated land, this will damage them, and in the mountains and fields, it will damage trees, so they are cut down when necessary, but in either case, special care is required and the strips are cut with high tension. The wire must be stretched so that it does not come into contact with objects below.

点が出てきている。However, due to the recent trend toward large-capacity power transmission, the diameter of power transmission lines has become thicker and the weight of the wires has increased, resulting in an increase in the tension that acts on the wires during wire extension, etc. Larger and more powerful machines and tools are required for this purpose, and problems have also arisen in the safety and workability of wire extension work.
このため、最近においては、低張力延線工法が検討され

置とをカッ、アロング工具を使用する緊線作業により引
き寄せて連結するものである。For this reason, low-tension wire drawing methods have recently been studied. The conventional method for this low-tension wire extension method is to suspend multiple hanging wheels at intervals from a hanging wire stretched between steel towers, pass the wire through these hanging wheels, and then transport the wire. The connecting metal fitting on the wire clamp side and the connecting metal fitting device on the insulator side are connected by pulling them together using a wire tensioning operation using an along tool.

At the same time, a wire 7 such as a power transmission line connected to the wire 4 via a connecting fitting 5 and a tension clamp 6 is also passed through the hanging wheel 3 and extended, Next, as shown in FIG. 11, a come-along tool 9 connected to the steel tower 1 by a cable 8 is fixed to the filament 7, and the filament 4 is removed.
The tension clamp 6 was pulled together and connected to a connecting fitting 10 connected to the steel tower l via an insulator link (not shown).

However, the work of fixing this come-along tool 9 to the wire 7 is carried out by a worker stepping out from the steel tower onto the wire 7 side, which is dangerous as there is a risk of the worker falling. There was a problem in that there was a risk that an accident could occur due to the fall of objects such as the like.

張力延線工法。1. Suspend multiple hanging wheels at intervals from a hanging wire strung between steel towers, extend the transmission line by passing it through each hanging wheel, and carry out transmission during the wire tensioning work. In the low-tension wire drawing method for overhead transmission lines, which connects the connecting device on the wire clamp side and the connecting device on the insulator side, both ends of a short round bar are formed into an almost hemispherical shape, and the A tension clamp side connecting hole is provided at one end to connect with the tension clamp connected to the power transmission line.
A connecting hole on the insulator side is provided at the other end, a recess into which the head and nut of the connecting bolt can be inserted is provided around the tension clamp side connecting hole and the connecting hole on the insulator side, and a recess is provided in the middle of the round bar body. A tension clamp attached to the end of the wire of the power transmission line to be connected is attached to the main body of the wire extension/tension line connector, which has a tension line connection hole for connecting the power line connector to the body of the power line. A connecting fitting on the insulator side connected to the tension clamp side connecting hole of the connecting device main body and connected to a filament such as a wire or rope is connected to the insulator side connecting hole of the connecting device main body, and this connecting device The wire connected through the main body is passed through a hanging wheel suspended from a hanging wire stretched between the steel towers, and the wire is extended by pulling it, and then the wire is extended through one connecting hole of the three-hole fitting connected to the insulator chain side. and a tension line connector connected to the tension line connection hole of the connector main body, are pulled together by a tension pulley device to tighten the line, and the other connection hole of the three-hole fitting is connected to the wire or rope. A connecting fitting device is inserted and connected between the connecting fittings on the insulator side from which the wires have been removed, and then the device used for the wire tensioning work is removed to complete the erection of the power transmission line. Low-tension wire extension method for power transmission lines.
