ーニヤ金具の間隔調整を効果的に行うためには不可欠の
ものであるが、近年、送電線の大サイズ化に伴って工具
の能力アップが要求され、このため、工具の大型化し、
また、大重量化になる欠点があった。The above-mentioned conventional tool is indispensable for effectively adjusting the interval of the vernier metal fittings, but in recent years, the capacity of the tool has been improved with the increase in size of the transmission line. Is required, which results in larger tools and
Further, there is a drawback that the weight becomes large.

してしまう。Explaining further using the conventional tool b shown in FIG. 2, the load acting on the hydraulic cylinder 40 is a compressive load corresponding to the tension of the transmission line. This compressive load increases as the size of the transmission line increases,
In order to cope with this large compressive load, a large cylinder is required, which makes the tool b large and heavy.

まれていた。In addition, when the tensioning work is performed by the prefabricated construction method, the adjustment range of the vernier fitting may have to be increased. This is because in this prefabricated construction method, there is a large error between the assumed set dimension and the actual working dimension at the time of work, and a large adjustment range of the sag is often required. Therefore, it has been desired to maximize the interval adjustment range of the vernier metal fittings.

The interval (required adjustment interval for vernier metal fittings) changes.
【００３１】この間隔の変化について、本実施例に係わ

By rotating around the holes 8 and 8 of b, respectively, a change in the interval of about B / A times the expansion / contraction length of the cylinder rod 20a is obtained.

The interval adjustment range can be set to a large value. For this reason,
When it is desired to obtain the same change in spacing, the tool a according to this embodiment is used.
Since the stroke of the cylinder rod 20a is small, it can be seen that a small hydraulic cylinder 20 is sufficient.

Since a large gap adjustment can be performed without increasing the size of the metal fitting pieces 6a, 6b and the hydraulic cylinder 20, it is possible to cope with a vernier metal fitting 1 having a large adjustment allowance with a weight equivalent to that of the conventional tool b.
【００３７】本実施例に係る工具ａを用いてのバーニヤ
金具１の調整作業は、上記従来の工具ｂのときと同様で

However, one of the metal fitting pieces 6a, 6b is connected to the vernier metal fitting. You may make it connect directly to one plate-shaped piece 1a or 1b. For example, the metal fitting piece 6a is connected to a connecting metal fitting (not shown) provided further to the tip side of the connecting metal fitting 2a, and the metal fitting piece 6b is connected to a hole (not shown) provided in the plate-shaped piece 1b. Good. On this occasion,
If there are at least three bending points of the connecting metal fittings between the metal fitting pieces 6a and 6b, the hole position of the vernier metal fitting 1 can be easily adjusted, which is desirable. Therefore, in the present invention, the term “a pair of metal fitting pieces having a mounting portion for connecting the vernier metal fitting” to the vernier metal fitting 1 includes directly connecting either one of the metal fitting pieces 6a and 6b.

って、プレハブ工法における多導体の弛度調整作業を容
易に行うことができる。The tool according to the present invention is a pair of tools having longitudinal directions substantially parallel to each other and spaced from each other by a predetermined distance, and having a mounting portion for attaching a vernier metal fitting to a connecting metal fitting at one longitudinal end thereof. Between the fitting part of the vernier fitting and the mounting position of the rod to the other end of the pair of fitting pieces, the both ends of which are rotatably connected. Since the reciprocating drive mechanism has both ends rotatably connected to each other, it is possible to reduce the size and weight of the tool itself and to increase the interval adjustment range of the vernier metal fittings. Therefore, the work of adjusting the degree of slack of the multiconductor in the prefabricated method can be easily performed.
