Abstract

PURPOSE:To improve the work efficiency by providing a tension detector on a turnbuckle for omitting such troublesome work as connecting a tension-meter between the turnbuckle and an overhead line. CONSTITUTION:A turnbuckle is provided with a turnbuckle main body 3 composed of a rotating part 1 and non-rotating parts 2 screwed on both ends of the rotating part 1 by inverse screws. A tension detector 4 is equipped on the non- rotating part 2 of this turnbuckle main body 3. For working, a shaft 5 is rotated to slide a slide nut 9 along the shaft 5 for adjusting tension. At this stage, the movement of the slide nut 9 in that direction is limited by a stopper 7. Meanwhile, the tension given to the turnbuckle main body 3 is detected by a tension detector 4.

FIG. 4 shows a third embodiment of the turnbuckle according to the present invention. In the turnbuckle main body 3 of the turn socket of this embodiment, the rotating part 1 does not consist of a rotating sleeve 33, the non-rotating part 2 does not consist of a hook bolt 34, and both ends of the inner surface of the rotating sleeve 33 have reverse threaded parts 35. is carved, and a reverse threaded portion 36 of the hook bolt 34 is screwed into this reverse threaded portion 35. A ratchet wheel 37 is fixed to the center of the outer periphery of the rotating sleeve 33, and the ring portion 38A of the handle 38 is attached to the rotating sleeve 33 by sandwiching the ratchet wheel 37.
A ratchet wheel 39 is rotatably fitted to the handle 38 and cantilevered by the handle 38, and is engaged with the ratchet wheel 37.
By reciprocating the handle 38, the multi-rotation sleeve 33 is rotated in a predetermined direction. A tension detector 4 having the above-described structure is attached to the outer periphery of one hook bolt 34, which is the non-rotating portion 2.

As explained above, since the turnbuckle according to the present invention is equipped with a tension detector at its non-turning portion, the troublesome work of connecting a tension meter between the turnbuckle and the overhead wire during overhead wire work is omitted. It is possible to improve work efficiency. Also, for example, 6 conductors, 10
Conventionally, when adjusting the tension of a large number of overhead wires such as conductors, it was necessary to use tension meters according to the number of wires, but according to the present invention, these are no longer necessary, so the economic effect is also great. It is also suitable from the viewpoint of work safety. Furthermore,
It goes without saying that the turnbuckle of the present invention can be used not only for overhead wire work, but also for other purposes.
