る。At the beginning of use, for example, the initial use mark 19 of the one-piece link 5 which is located substantially at the tip of the clevis portion 17 of the clevis link 4, the contact wear due to the repeated rotation of the rotation connecting portion progresses. The distance from the tip of the clevis portion 17 increases. Therefore, unlike the conventional method of empirically determining the time to replace the overhead wire fittings based on the degree of rust and abrasion powder around the rotary joint, the degree of corrosion, the conditions of use, etc. You can check the degree of
It is possible to determine whether or not it is near the time to replace the metal fittings even if the black 18 does not appear. When the wear further progresses and the marginal wear mark 18 appears at the tip of the clevis portion 17, it is time to replace the overhead wire fittings, so that it will be replaced with a new one.

17, 37 and link parts 13, 20, 31 and bolts 12,
It is calculated from the total amount of displacement due to the wear of the rotary connection portion composed of 22 and 32. Since the total amount of displacement due to this wear varies depending on the material, size, load, usage conditions, etc. of the pivotal connecting portion, the limit wear mark 18 may be applied to the bolt hole 16 as shown by the phantom line in FIG. . The limit wear strength is
Set from maintenance standards (customer specifications) for overhead power lines and overhead ground lines. Generally, the actual breaking strength is 1.5 of the tensile strength of overhead wire fittings.
Although it is about double to 2.0 times, the relationship between the limit wear strength and the actual fracture strength in the wear resistant design is further increased.

する。The wear amount markings at the clevis portion of the overhead wire fitting and the link portion of the overhead wire fitting have been described above. Regarding the rotary connection location of the clevis portion of the overhead wire fitting and the yoke portion of the overhead wire fitting. However, the idea of wear amount marking is the same except that the link portion is replaced with the yoke portion. For example, as shown in FIGS. 8 and 9, in the conductor tensioning device that connects the ground-side yoke 40 to the tower arm through the right-angle clevis 41, the right-angle clevis link 42, etc., the ground-side yoke 40 is used. The initial mark 19 is provided at a position almost coincident with the tip of the clevis portion 46 of the right-angled clevis 41 at the start of use, and the limit wear mark 18 is at the time when the strength of the apex of the yoke is reduced to the limit wear strength. The total displacement amount due to the wear of the rotary connecting portion is carved near the bolt hole 44 from the initial use mark 19.
