The device was developed in 1977.
-1531. A drum wheel was rolled along the electric wire by being towed from the ground, and a circular saw that rotated integrally with the drum wheel was used to break the kite. It tends to get wedged between the end face of the drum wheel and the corresponding surface of the frame, and get wrapped around the shaft, making it impossible for the drum wheel to rotate. Even if a circular saw is fixed to the end face of the drum wheel, the same trouble will occur between it and the frame.

ある。[Example] The drawings will be explained using an example in which a circular saw is fixed to the end face of a drum wheel. The frame 1 has a long side 1a and a short piece 1b in the shape of a key, and a hanging handle 1c is provided on the long side. The frame body 2 has an inverted U shape and is fixed to the inside of the long side 1a. The drum wheel 3 made of insulating material has a hollow inside.
It is rotatably supported within the frame 2 by a shaft 4, and circular saws 5 are fixed to both sides thereof. The fixed saw 6 is fixed to the long side of the frame and the frame opposite thereto, and is positioned so that at least a portion thereof overlaps within the circle projected by the circular saw. A vertical screw hole is bored in the short side 1b, and a screw rod 7 is screwed into the hole. The operating rod 8 made of insulating material is attached to the lower end of the threaded rod 7, and is provided with a tow rope handle 8a at the lower end. Closure piece 9
is rotatably attached to the upper end of the threaded rod 7, but is prevented from rotating by engaging with the long side 1a, so that it can be raised by rotation of the threaded rod and close the lower opening of the frame 2. . An annular flange 5a is fixed to the outer surface of the circular saw 5, and an annular flange 2a is fixed to the corresponding inner surface of the frame. The flanges have different diameters and overlap each other by an appropriate length, but a slight gap is left between the flanges so as not to impede free rotation.

る。 The present invention is constructed as described above. The drum wheel is placed astride the electric wire, the frame body is closed with a closing piece, and the drum wheel is pulled with a rope connected to the handle 8a. The kite is broken by the saws 5 and 6 and can be removed. At this time, even if the kite string gets between the circular saw and the frame, it will be blocked by the flanges 5a, 2a and will not affect the rotating shaft 4.
In addition, in snowy areas, electric wires are often equipped with anti-snow rings, but in this case, if a plurality of axial protrusions 3a are provided at equal angles on the surface of the drum wheel 3 as shown in Fig. You can cross the ring.

［効果］凧取作業で多発した凧糸の巻きつきによる丸鋸
の回転不能事故を絶無とすることができる。[Effect] It is possible to eliminate accidents in which the circular saw cannot rotate due to the kite string becoming entangled, which frequently occurs during kite catching work.
