いつたものであつた。<Conventional technology> The conventional overhead line method generally consists of installing a wire stretching device at the drum station and a overhead line winch at the engine station, installing a metal wheel on each tower in the overhead line section, and then unwinding the line from the wire stretching device. While the wire is supported by a wire wheel and wound up by an overhead line winch, the wire stretching device or the overhead line winch itself is equipped with a wire stretching tension detecting means, and based on the tension information from the wire stretching tension detecting means, the drum field and the engine field are The line was to be laid at a predetermined tension while communicating with other workers as appropriate.

に余計な負担を掛けてしまうことになつていた。<Problems to be Solved by the Invention> By the way, maintaining a predetermined wire tension during overhead line work is aimed at taking care of obstacles below the overhead line section. However, the situation with these obstacles is different for each tower section, and as in the conventional overhead line method, the line tension is detected by a line tension detection means installed in the line stretching device or the catenary winch itself. If the wire tension is controlled only by information, and moreover, only by controlling the unwinding state of the drum station or the winding state of the engine station, the purpose of maintaining the predetermined wire tension is indirectly achieved. It is difficult to carry out overhead line work in accordance with the actual circumstances of the environment, and in the end the overhead lines are stretched with a tension higher than necessary, which places an unnecessary burden on the wires, towers, tools (e.g. metal wheels), etc. I was getting used to it.

線等に余計な負担が掛かるものであつた。 In addition, in the conventional overhead wire method, when the protector passes the wire wheel, the movement of the wire is temporarily stopped until the protector is inserted into the wire wheel, so the engine temporarily moves past the wire wheel. A very large wire tension was generated on the field side, and as a result, an unnecessary burden was placed on the electric wires, etc.

ものである。 In view of such conventional circumstances, in this invention,
In addition to detecting tension information that matches the actual circumstances of the overhead wire environment, it is possible to perform partial wire extension tension control for each desired tower section, making it possible to perform wire extension tension control that is more in line with the actual situation, and at the same time detect abnormalities when the protector passes through the wire wheel. It is an object of the present invention to provide an overhead line method that can eliminate the generation of tension and thereby avoid placing unnecessary burdens on electric wires, etc.

る。<Function> That is, for example, by directly obtaining tension information from a steel tower section where accurate control of the tension state is required because there are obstacles below, and by sending this tension information to the drum station or engine station, the It is possible to perform wire tension control in accordance with the actual situation of the overhead line environment, and by using this tension information to perform so-called partial wire tension control for the relevant tower section using a powered metal car, it is possible to reduce the overall wire tension. Since there is no need to change the wire, the overall drawing tension level can be lowered than in the past. As a result, unnecessary burdens on electric wires and the like can be avoided.

This also means that workability (efficiency, safety, etc.) can be improved by reducing the weight of tools.

ようにしている。 In this overhead line method, a wire extension tension detecting means 1 is provided for each steel tower T 1 , T 2 , . (not). Then, the wire tension detection means 1 detects the wire tension state for each tower section S 1 , S 2 , ..., and using this tension information,
In addition to controlling the feeding state at the drum station D and the winding state at the engine station E, it also controls the braking and feeding functions of the power metal wheel 2, ie, the operating state, which will be described later.

段いずれであつてもよい。 The wire extension tension detection means 1 is preferably a so-called "angle tension meter" that detects the hanging load of the power metal wheel 2, but is not necessarily limited to this, and any conventionally known means may be used.

できるように細長状のものとしている。 In addition to wheels 3 similar to conventional ones, the power metal wheel 2 has an airtight outer shell made of an elastic material with a large coefficient of friction, specifically a rubber material, and has a compressed gas inside, specifically a rubber material. shows a pair of elastic rollers 4 filled with air and the operating state of the elastic rollers 4, that is, the electric wire 5.
It consists of a control mechanism 7 for controlling the electric wire 5 to either apply a braking force, or conversely, apply a feeding force (driving force) to the electric wire 5, or allow it to freely rotate. A wire guide means 8 is provided which can be freely held. The elastic roller 4 is formed into an elongated shape so that it can cope with changes in the entrance angle of the electric wire 5.

鉄塔Ｔ、工具類等に掛けずに済むことになる。 Therefore, for example, it is possible to directly obtain tension information from the tower section S2 , which requires particularly accurate control of the tension state because there is an obstacle 10 below, and to send this tension information to the drum station D to the engine station E. Therefore, it is possible to perform wire extension tension control that is more in line with the actual situation of the overhead line environment, and this tension information can be used to control the operating state of the powered metal wheel 2, so to speak, to partially control the tower section S2 . By controlling the wire tension,
It is also possible to avoid changing the overall wire drawing tension, and in any case, the overall wire drawing tension level can be made lower than in the past. As a result, unnecessary burden is placed on the electric wire 5,
There is no need to hang it on the steel tower T, tools, etc.

負担を掛けずに済むることになる。 In addition, since the protector 11 itself is forced to pass through the power metal wheel 2 by the elastic roller 4 operated as a "feed" (Fig. 2), it is possible to eliminate the occurrence of abnormal tension due to a temporary stop as in the conventional case. Similarly, unnecessary burdens on the electric wires 5, the steel tower T, tools, etc. can be avoided.

を図れることにもなるものである。 In addition, the fact that there is no unnecessary burden on the steel tower T, tools, etc. means that the required strength of the steel tower T, tools, etc. can be lower than before, so one of the reasons is the economical design. becomes possible,
Another advantage is that work efficiency can be improved by reducing the weight of tools.
尚、この実施例に用いた動力金車２は車輪３が
１個の１輪形のものであるが、勿論多輪形のもの
を使用することも可能である。 Although the power metal wheel 2 used in this embodiment is a one-wheel type having one wheel 3, it is of course possible to use a multi-wheel type.

付随的効果へ結びつくものである。<Effects of the Invention> As explained above, the overhead line method according to the present invention includes providing a wire extension tension detection means on a desired steel tower and providing a motorized metal wheel equipped with a wire guiding means that can be braked and fed freely. Therefore, it is possible to perform wire tension control that is more in line with the actual situation of the overhead line environment.In addition, partial wire tension control using a powered metal wheel using this tension information allows the wire tension to be controlled without changing the overall wire tension. In addition, by forcing the protector itself to pass through a powered metal wheel using an elastic roller, it is possible to eliminate the abnormal tension caused by a temporary stop as in the conventional method, thereby eliminating unnecessary burdens on electric wires, towers, tools, etc. It has the excellent effect of being able to conduct overhead lines without having to hang it, and this effect means that the required strength of steel towers, tools, etc. can be lower than before.
