Description

[Detailed description of the invention] (Field of industrial application) The present invention is a cable spanning suspension wire guide device, more specifically, a suspension wire guide device for cable spanning, which is installed in a row of utility poles so that the cable spanning suspension wires can be raised and lowered. The present invention relates to a suspension line guide device that guides the cable so that it can be raised and lowered.

(Prior Art) Conventionally, as a means of spanning cables between rows of utility poles, a tension fitting provided at the top of the utility pole is used.
Only the suspension wire is hung in advance and the suspension wire is stretched, while the cable is stretched over the suspension wire with a cable ring using a crane truck or the like.

However, in the case of the above-mentioned conventional cable spanning means, the cable must be strung on the hanging wire at a high place after the hanging wire has been stretched on the tensioning device of the utility pole in advance, which reduces the construction period. As it grows longer,
This requires a great deal of labor, and since the work of stretching the cable to the suspension wire is carried out at a high place, it is very dangerous and difficult to work.

Therefore, as a means of solving the above problem, a lifting device is installed on the utility poles located at both ends of the row of utility poles to allow the retaining device that holds the hanging line to be raised and lowered from a low position to a high position on the pole. A hanging wire is stretched along each utility pole while being positioned at a waist height position, and the hanging wire is positioned at a waist height position, and
It is conceivable that a cable is attached to the suspension line via a cable ring, and then the suspension line is raised to a high position on the utility pole by driving the lifting device, and the suspension line is supported by a tensioning frame.

(Problem to be solved by the invention) However, when using such a cable installation means, when the suspension wire is raised to near the tensioning device on the utility pole by the lifting device, the suspension wire is not strung with the cable attached. Therefore, if a row of utility poles is not arranged in a straight line but in a bent shape, the hanging wire installed outside of the utility pole located at the bend will be curved along the outer surface of the utility pole. However, the suspension wire is pressed against the outside surface of the utility pole, making it difficult to move up and down smoothly, and the suspension wire installed inside the utility pole is pulled greatly inward from the utility pole, causing the suspension wire to be pulled close to the inside surface of the utility pole. There was a problem that made it difficult to follow the guidelines.

The object of the present invention is to prevent the hanging wire for cable installation from being lifted or lowered to a desired height position on a utility pole by a lifting device under tension, or when the suspension wire is pressed against the outside surface of the utility pole and cannot be lifted or lowered. To provide a suspension wire guide device for cable spanning which can smoothly guide the suspension wire up and down along a utility pole without being pulled in greatly to one side.

(Means for Solving the Problem) Therefore, the present invention is a suspension wire guide device that guides a cable spanning suspension wire that is movably strung up and down along a row of utility poles in a manner that it can be raised and lowered along the utility pole. , a wheel 2 that rolls in contact with the utility pole when the one side faces the utility pole is freely rotatable via an axle 2a orthogonal to the vertical direction. At the same time, a guide roller 3 that engages with a guide cable attached in the length direction of the utility pole is freely rotatable on the other side of the trolley body 1 via a support shaft 3a parallel to the axle shaft 2a. While supporting
A retaining ring 4, which engages and holds the suspension wire midway, is supported at an intermediate portion between the wheel 2 and the guide roller 3 via a vertical shaft 4a that extends in the up-and-down direction.

(Function) With the above configuration, when lifting or lowering a cable spanning suspension wire that is press-contacted to the outer surface of a utility pole, the wheels 2 of the trolley body 1 are attached to the outer surface of the utility pole, and the retaining ring 4 is attached to the By hanging the suspension line and moving the trolley body 1 using the guide rope 24 as a guide due to the rolling of the wheels 2, the suspension line can be smoothly raised and lowered along the utility pole, and it can also be moved in the direction away from the utility pole. When raising and lowering the tensioned hanging wire along the utility pole, the guide cable 24 attached in the length direction of the utility pole prevents the trolley body 1 from moving away from the utility pole via the guide roller 3,
In such a state, the hanging wire is hung on the retaining ring 4, and the trolley body 1 is moved using the guide rope 24 as a guide, so that the hanging wire is not pulled inward from the inner surface of the utility pole. , and are raised and lowered along utility poles.
