The parallel clevis 11 and the ground side 2 of the three-point support twin tension device 51 shown in FIG.
The continuous yoke 12 becomes unnecessary, and the length of the apparatus can be shortened. For this reason, the compression clamp 88 of the triple tension device 71 of the old device is diverted to the electric wire clamp 88 while the electric wire is clamped, and the wire side yoke is independent vertical and horizontal yokes. Even if it is configured, it can have the same length as the old three-unit tension device with a margin, so that the work of adjusting the sag when the electric wire is stretched becomes unnecessary.

る。The ground-side balance yoke 14 is connected to the intermediate connecting point 5 and both ends connecting points 5, 5 by connecting metal fittings 2, 3 connected to three mounting points 1, 1, 1 of the existing support arm 72, respectively. And the middle between the two connecting jigs 4 and 4 connected to each other, and the inside between the connecting fittings 5 and 5 of each yoke 4 is divided into two times the ratio of the outside to the intermediate connecting point 6. It comprises two parallel links 7, 7 having one end connected to each other and having the same length, and a horizontal yoke 8 connected to the other ends of the two parallel links 7, 7 taken in parallel. The horizontal yoke 8 and the ground-side double yoke 12 of the double tension device are connected at one end to a middle point 10 of both link connection points 9 and 9 of the horizontal yoke 8 and at the other end. Are connected by the parallel clevis 11 connecting to the apex portion 13 of the ground side double yoke 12 having an isosceles triangular shape.
The yoke 14 is all composed of a yoke having an offset of zero, so that no imbalance occurs even when there is a wind. In addition, FIG.
As shown in (1), even when the support arm 72 is mounted at a position having a horizontal angle, the yokes 4, 4 and the horizontal yoke 8 are juxtaposed to a straight line connecting the three mounting points 1, 1, 1 of the existing support arm 72.

The configuration other than the ground vernier bracket 35, the ground side balance yoke 37 and the line side yokes 39, 41, 45 is substantially the same as that shown in FIG. Ground side balance yoke 3 shown in FIG.
Reference numeral 7 denotes a ratio twice as large as that shown in FIG. 1 between two juxtaposed yokes 4 and 4 and the inner side between both connecting metal fittings connecting points 5 and 5 of each yoke 4. And two parallel links 7, 7 having the same length and one end connected to the intermediate connection point 6, and a yoke 36 on the insulator side connected to the other end of the two parallel links 7, 7 taken in parallel. The yoke 36 on the insulator side
Is connected to the ground side of the double tension device by connecting the double insulator rows 16 and 16. Therefore, FIG.
The horizontal yoke 8 and the parallel clevis 11 shown in FIG. 1 are not required, and the length of the apparatus can be shortened.
As shown in FIG. 1 (b), ground side vernier brackets 35, 35, 35 for tilting the side-by-side yokes 4, 4 and the horizontal yoke 36 in a direction having a horizontal angle are required. However,
As shown in FIG. 9, the ground side vernier bracket 35 can be used with a short length, so that the ground side yoke connecting point of the two insulator trains 16, 16 is connected to the mounting point of the support arm 72. 1,1,1
Is shorter than that of the three-point supporting double tension device 51 shown in FIG. For this reason, when the compression clamp 88 of the old triple tension device 71 is diverted to the electric wire clamp while the electric wire is clamped, and when the same length as the triple tension device 71 is used, the adjustment of the wire sag adjustment is omitted. The side yoke is a multi-conductor fixed yoke 20 in the three-point supporting double tension device 51 shown in FIG.
However, this can be constituted by a vertical yoke 39 and horizontal yokes 41 and 45 which are independent from each other.

Since the total load acts on the middle point 10 of the horizontal yoke 8 even if the loads applied to the two connecting points of the insulators of the continuous yoke 12 are different, the three mounting points 1, 1, 1 of the existing support arm are provided. With 1 the load can be shared equally and no imbalance occurs. FIG.
As shown in FIG. 10 (b), not only the mounting position having a horizontal angle of zero as shown in FIG. 10 (a) but also the mounting position having a horizontal angle as shown in FIG. Since the yoke 8 is always parallel to the straight line connecting the mounting points 1, 1, 1 of the existing support arm 72, the ground side vernier bracket is unnecessary regardless of the presence or absence of the horizontal angle.

Except for the point constituted by the yoke 36 and the configuration of the line-side yoke, the structure is substantially the same as that of the three-point supporting double tension device 55 shown in FIG. As a result, the one shown in FIG. 2 has more ground side vernier brackets 35 than the one shown in FIG. 1, but the intermediate yoke 8 and the single link 11 are unnecessary.

The compression clamp is used with the wire clamped, and has the same length as the triple tension device 71 so that the wire slackness does not change even if the tension device is replaced. For this reason, when the device length is longer than the triple tension device 71, the three-point supporting double tension device 51 shown in FIG. By doing so, the length is made the same as the triple tension device 71.

る。As described above, according to the present invention, the ground side balance yoke is connected to the three mounting points provided on the existing support arm for mounting the triple tension device via the connecting metal fittings. The ground-side balance yoke is connected to the ground-side double yoke of the existing double tension device at one point, or the ground-side double yoke is connected to the ground-side balance yoke insulator. Because the side yoke is also used, the existing support arm is not modified, and most of the existing double tension yoke after the ground side double yoke or after the double insulator row are used. The connection fitting can be used, and the production cost and replacement construction cost of the three-point supporting tension device that replaces the triple tension device of the old device can be reduced.
