BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cable wrap prevention device used to prevent wrapping of a cable around a cable drum.

[0002]

2. Description of the Related Art For example, in the work of replacing overhead wires, a plurality of cables (electric wires) stretched in parallel on a utility pole are simultaneously wound on a plurality of cable drums prepared for each cable. Often. When such a work is performed, a cable turbulence prevention device that controls each cable so that the cable is not turbulently wound on each cable drum is used. This cable turbulence prevention device is arranged on the near side in the winding direction of each cable drum, and a plurality of guide means for winding and guiding each cable to each cable drum,
Traverse means for reciprocating each guide means in the axial direction of each cable drum.

[0003] In the cable turbulence preventive device constructed as described above, each cable is aligned and wound on each cable drum by reciprocating each guide means on the support shaft by a traverse means at a constant speed. Can be. By adjusting the reciprocating speed of each guide means by the traverse means according to the diameter and length of the cable, it is possible to wind various kinds of cables.

[0004] By the way, cables (electric wires) include, for example, a set of four low-voltage cables and a set of three high-voltage cables, which have different diameters and lengths. . For this reason, even when these cable winding operations are performed, cable drums having different diameters and widths are used.

[0005]

However, in the conventional cable turbulence prevention device, the reciprocating stroke (width) of each guide means by the traverse means is set for winding one of the low-voltage cable and the high-voltage cable. It could not be changed. For this reason, it is necessary to use a cable turbulence prevention device that differs depending on whether the cable to be wound is for low pressure or high pressure, and there is a problem that it is troublesome.

The present invention has been made in view of such a problem, and an object of the present invention is to provide a cable turbulence prevention device which can cope with winding of various cables having different diameters and lengths.

[0007]

In order to achieve the above object, in the cable turbulence prevention device of the present invention, each guide means is connected to each cable so that each cable is aligned and wound on each cable drum. Traverse means for reciprocating in the axial direction of the drum is provided. The traversing means includes a traverser shaft having a plurality of helical grooves formed by a shaft member arranged to extend along a plurality of guide means and having a fold length different from each other. And a funnel which is detachably attached to the guide means and is selectively received in the plurality of folded spiral grooves.

The funnel may be detachably attached to one of the plurality of guide means, and the guide means to which the funnel is attached and detached may be connected to other guide means by connecting means.

[0009]

In such a cable turbulence prevention device, the funnel attached to the guide means is received in a folded spiral groove having a folded length corresponding to the width of the cable guide. In this state, when the traverser shaft is rotationally driven by the driving means, the guide means reciprocates with a stroke corresponding to the width of the cable guide. In this manner, the cable can be aligned and wound with respect to the cable guides having different widths only by changing the folded spiral groove for receiving the funnel. For example, a cable turbulence prevention device for both the high-voltage cable and the low-voltage cable is provided. Can be

If the funnel is attached to one guide means and this guide means and other guide means are connected by a connecting means, the return spiral groove formed on the traverser shaft will be different for each return length. One by one is enough.
