[Detailed description of the device]

[Industrial applications]

 The present invention relates to a winding tool for winding a spiral rod around an electric wire in order to reduce noise generated on the electric wire by wind.

[0002]

[Prior Art]

 Electric wires make noise due to wind. The sound spreads far away along with the wind, making people in a large area uncomfortable. It has long been known that this sound can be reduced by winding a wire around an electric wire in a spiral shape. In other words, if the surface of the wire is smooth, sound is likely to be produced, and if it is rough, it is difficult to produce. A metal wire having a length of about 2.5 m, which is made into a spiral with an appropriate pitch in advance, is commercially available under the name of a spiral rod, and this wire is wound around the electric wire one after another to roughen the surface.

Conventionally, all of the windings have been done manually. It was a very inefficient work involving three people, one who held the tip winding part, the other who did the winding work, and one who operated the remaining spiral rod so that it would not get tangled behind it.

[0004]

[Means for solving the problem]

 An electric wire will pass through and an outer cylinder that can move freely along the wire will be installed, and an eye part will be attached to the head. An arm of appropriate length is projected at the middle part, and an eye part is also provided at the tip. Pass both eye parts through the spiral rod whose end is locked to the wire, and pull the outer cylinder toward the tail. The outer cylinder rotates and the spiral rod is wound around the wire. Since the rear part of the spiral rod is separated from the electric wire by the arm, even if the outer cylinder rotates, it can be naturally driven by it.

[0005]

【Example】

 Fig. 1 shows a wrapping tool that simultaneously winds two spiral rods S with different phases. The spiral rod S is made of aluminum, and the diameter of the spiral is slightly smaller than the wire.

The outer cylinder 1 is a cylinder in which half halves are combined, holds an electric wire E, and is freely rotatable along the electric wire. The ring 2 is a hinged combination of halves, and is fixed to the outer cylinder by covering the outer cylinder with the free end tightened. The ring 2 is provided with two cannabis 2a diametrically. The canavilla 2a is an annular body that allows the spiral rod S to be freely inserted, but a part of the outer circumference is an opening / closing side into which the spiral rod can be inserted from the side by pressing. After insertion, it automatically closes with spring force. The ring 3 is also made of a half body and is fixed to the outer cylinder. The ring 3 has two arms 3a protruding in the diametrical direction, and a cannabila 3b is provided at the tip thereof. The ring 4 is composed of two inner and outer layers. The inner ring 4a is fixed to the outer cylinder 1, and the outer ring 4b is rotatably inserted in the inner ring. The outer ring projects the lever 4c laterally.

[0007]

[Action]

 The two ends of the spiral rod can be wound around the wire manually by changing the phase by 180 degrees. Since the diameter of the spiral is slightly smaller than that of the wire, it can be locked to the wire as it is by winding. Insert this spiral rod into the canabira in order of ring 2 and ring 3. When the lever 4c is pulled to the right in the figure, the outer cylinder moves while swirling along the spiral, and the spiral rod is guided by the ring 2 and winds around the electric wire. Since it is separated by an arm, the two spiral rods do not get entangled. After installing the start end by hand, one person can work easily.

[0008]

【effect】

 It is possible to wind automatically just by towing the lever. One person can easily do the work that was done by three people.
