  Next, an example of a method of using the flying object removing device 100 according to the present embodiment will be described with reference to FIG. As shown in FIG. 5, the flying object removing apparatus 100 is operated by the worker WM. In the present embodiment, the flying object removing device 100 is attached to the tip of a work tool 200 called an operation rod. The work tool 200 has a gripping portion formed of an insulating member (insulating material), and the worker WM operates the flying object removing apparatus 100 by gripping (holding) the gripping portion.

  When the flying object F adheres to the overhead line K (or a structure such as a steel tower or a column that supports the overhead line K), the flying object removing device 100 so that at least a part of the flying object F is wound around the holding member 2. Is operated. The holding member 2 winds and holds at least a part of the flying object F.

  The flying object removing device 100 is operated so that the traveling roller 6 and the surface of the overhead wire K are in contact with each other, and the flying object F and the cutter 5 are in contact with each other. As a result, as shown in FIG. 5, a part of the flying object F is held by the holding member 2 while the slide mechanism 4 is supported by the overhead wire K, and a part of the flying object F comes into contact with the cutter 5. It becomes a state. In the example illustrated in FIG. 5, the slide mechanism 4 is disposed so as to straddle the overhead line K from above the overhead line K in a state where the holding member 2 is disposed above (+ Z direction) than the slide mechanism 4. As shown in FIG. 4, the slide mechanism 4 is disposed so as to straddle the overhead line K from below the overhead line K in a state where the holding member 2 is disposed above (+ Z direction) than the slide mechanism 4. May be.

  The slide mechanism 4 can move the overhead wire K in a state where a part of the flying object F is held by the holding member 2 and a part of the flying object F is in contact with the cutter 5. The worker WM holds the part of the flying object F on the holding member 2 and the sliding mechanism 4 moves the overhead line K along the axis Jk in a state where the part of the flying object F is in contact with the cutter 5. In addition, the flying object removing apparatus 100 is operated. Thereby, at least a part of the flying object F is cut by the cutter 5. Since a part of the flying object F is held by the holding member 2, the cutter 5 comes into contact with the flying object F in a state where the flying object F is stretched, so that the flying object F can be easily cut. After at least a part of the flying object F is cut by the cutter 5, the worker WM can collect the flying object F held by the holding member 2.

The travel roller 61 and the travel roller 62 have a distance between the rotation axis J61 of the travel roller 61 and the rotation axis J62 of the travel roller 62 as Z. It arrange | positions so that it may become large toward the other side from one side regarding an axial direction. As a result, as shown in FIG. 6, even if the thickness (outer shape, diameter) of the overhead wire K changes, the traveling roller 61 and the traveling roller 62 contact the surface of the overhead wire K, and the first member 41 and the first member 41 The slide mechanism 4 is supported by the overhead line K so that the two members 42 do not contact the surface of the overhead line K. Therefore, even if the thickness of the overhead line K changes, the slide mechanism 4 can move the overhead line K smoothly.

  As described above, according to the present embodiment, since the holding member 2 capable of winding the flying object F is provided, the flying object F can be stably held by the holding member 2. In addition, since the slide mechanism 4 that can move the overhead wire K while being supported by the overhead wire K is provided, for example, the holding member 2 can be easily brought close to the flying object F, and the flying object F is removed. Work can be performed efficiently. In addition, since the cutter 5 capable of cutting at least a part of the flying object F is provided in the slide mechanism 4, the cutter 5 can move stably along the overhead line K. Further, since the slide mechanism 4 has the traveling roller 6, the overhead line K can be moved while suppressing damage to the overhead line K. Further, since the holding member 2 is disposed at the tip of the shaft member 1 and the slide mechanism 4 is connected to the support member 3 that supports the shaft member 1, the slide mechanism 4 is supported by the overhead wire K. The flying object F existing at a location away from the overhead line K can be held by the holding member 2. A part of the flying object F is held by the holding member 2, and the slide mechanism 4 moves the overhead wire K in a state where a part of the flying object F is in contact with the cutter 5 provided in the slide mechanism 4. The flying object F in a stretched state can be smoothly cut by the cutter 5 that moves along the overhead line K. Thereby, the flying object removal apparatus 100 can perform the removal work of the flying object F efficiently and smoothly.

  Further, according to the present embodiment, the holding member 2 is disposed so as to protrude from the tooth portions 21 and the plurality of tooth portions 21 extending in a direction parallel to the axis J1 of the shaft member 1, and at least one of the flying objects F. And the hook part 22 that hooks the part can be used to smoothly wind up the flying object F using the tooth part 21, and the hook part 22 prevents the flying object F from being released from the holding member 21. The

  Further, according to the present embodiment, the travel roller 61 and the travel roller 62 are such that the distance between the rotation shaft J61 and the rotation shaft J62 increases from one side to the other side in the direction parallel to the axis J1 of the shaft member 1. Therefore, each overhead wire K having a different thickness is inserted between the traveling roller 61 and the traveling roller 62 and can contact the traveling roller 61 and the traveling roller 62.

  In the present embodiment, the slide mechanism 4 is rotatable about the axis J32 of the second support portion 32 as a rotation axis, and includes a first member 41 (traveling roller 61) and a second member 42 (traveling roller 62). The first state is arranged such that the interval between the Z-axis direction increases from one side (+ Z side) to the other side (−Z side) and the other side (−Z side) to one side (+ Z side) It is possible to change from one of the second states arranged so as to increase toward the other. As a result, as shown in FIG. 1 and the like, the holding member 2 is positioned above the slide mechanism 4 (+ Z direction) in a state where the slide mechanism 4 is disposed so as to straddle the overhead line K from above the overhead line K. As shown in FIG. 4, in the state where the slide mechanism 4 is disposed so as to straddle the overhead line K from below the overhead line K, the holding member 2 is positioned above the slide mechanism 4 (+ Z Direction). By disposing the holding member 2 above the slide mechanism 4, the flying object F positioned above the overhead line K on which the slide mechanism 4 is supported can be held by the holding member 2. Further, the holding member 2 can be disposed below (−Z direction) the slide mechanism 4 in a state where the slide mechanism 4 is disposed so as to straddle the overhead line K from above the overhead line K. The holding member 2 can be disposed below (−Z direction) below the slide mechanism 4 in a state where 4 is disposed so as to straddle the overhead line K from below the overhead line K. By disposing the holding member 2 below the slide mechanism 4, the flying object F positioned below the overhead line K on which the slide mechanism 4 is supported can be held by the holding member 2. In this way, at least a part of the flying object F positioned above the overhead line K and at least a part of the flying object F positioned below can be held by the holding member 2, and the flying object F is positioned at the position.
