Description

[Detailed Description of the Invention] (Field of Industrial Application) This invention relates to a tool used for removing binding wires from insulator attachment parts, etc. in so-called hotstacking work.

(Prior art) As shown in Fig. 4, a bind wire 2 made of aluminum or the like is tightly wrapped around the outer periphery of an electric wire 1 supported by an insulator, etc., near the insulator attachment part of a telephone pole, etc., but this should be removed. In this step, the bind wire 2 is cut in the longitudinal direction of the electric wire 1 (in the direction of the arrow in the figure) using a cutter tool or the like.

(Problems to be Solved by the Invention) However, since the binding wire 2 is tightly wound around the electric wire 1, the blade of the cutter tool cannot easily enter between the electric wire 1 and the binding wire 2.

(Means for solving the problem) Therefore, this idea was made based on the fact that if the binding line 2 is made loose in advance as shown in Fig. 5, the blade of the cutter tool can be inserted easily. The specific structure is that a large non-penetrating hole is drilled in the axial direction of the holding member, which is made of a column that can be split into two, allowing the electric wire to be held in the longitudinal direction from above, and A small diameter hole having a diameter slightly larger than the diameter of the electric wire is coaxially penetrated at the inner end of the large diameter hole, and a protrusion is provided on the step formed by the small diameter hole and the large diameter hole, The edge of this protrusion on the small diameter hole side is made to coincide with the inner peripheral surface of the small diameter hole.

(Function) After the holding member is divided into two parts, the protrusion in the large diameter hole is placed on the end of the bound wire, and the electric wire is stored in the small diameter hole, and then this holding member is shaped into a columnar shape. Hold the electric wire, then lock the end of the bound wire to the protrusion in the large diameter hole, and turn the holding member in the opposite direction to the winding direction of the bound wire, then the electric wire and one end of the bound wire will be removed. Since it is supported by an insulator or the like (see Figure 6), only the binding wire gradually loosens from its end.

(Embodiment) Hereinafter, an embodiment of this invention will be described with reference to the drawings. As shown in FIGS. 1 and 2, the holding member 11 according to the embodiment is approximately cylindrical and parallel to the axial direction. This holding member 11 can be freely divided into two parts, an A holding part 11a and a B holding part 11b, by means of a pin 12 provided at the end thereof. This holding member 11 has large diameter holes 13 and 14 bored in the axial direction from both ends thereof, respectively.
Furthermore, a small diameter hole 16 having a diameter slightly larger than the diameter of the electric wire is drilled from the inner end 13a of the large diameter hole 13 toward the inner end 14a of the large diameter hole 14 at the other end. Each step formed by the large-diameter holes 13, 14 and the small-diameter hole 16 has a substantially fan-shaped projection 1.
7 and 18 are provided respectively. These protrusions 17, 18
The edge on the side of the small diameter hole 16 is aligned with the inner circumferential surface of the small diameter hole 16.

An A gear 19a and a B gear 19b are provided on the end surfaces of the A holding part 11a and the B holding part 11b on the large diameter hole 13 side, respectively.
are fixed with bolts 20 and 21, respectively, so that when the A holding part 11a and the A holding part 11b are put together, they form an annular gear. Note that there is an annular guide groove 2 in the middle of the outer circumference of the holding member 11.
2 is formed.

The embodiment is constructed as described above, and in order to use it, as shown in FIG. It is held by the rotation support member 24.

That is, the existing rotation support member 24 has a mechanism for rotating a gear 25 that is a part of itself by using a bevel gear (not shown) or the like that has an internal rotation of the rotation shaft 23 of the rotary stake. Furthermore, a suitable cylindrical tool is stored in the approximately cylindrical holding member 26 provided at right angles to the holding member 26, and the holding member 26 and the rotatable approximately semicylindrical lid body 27 are closed to close the cylindrical tool. By holding the tool rotatably and providing the tool with an appropriate gear that meshes with the gear 25, the approximately circular shaped tool is rotated through the gear 25 by the rotation of the rotary shaft 23 of the rotary stick. It is designed to be rotated.

Therefore, specifically speaking, how to use this example is as follows.
First, fit the A holding part 11a into the holding member 26 of the rotation support member 24, and attach the A gear 1 to the gear 25.
Engage 9a. In this state, as shown in FIG. 2, the A holding portion 11a is hooked onto the part of the electric wire 1 where the binding wire 2 is not wound, and the rotating shaft 23 of the rotary stake is rotated as appropriate. Then, the gear 25 rotates, the A gear 19a meshed with it also rotates, and the A holding part 11a rotates, but at this time, the B holding part 11b, which is rotatable in the A holding part 11a, just holds the rotation support member 24. The substantially cylindrical holding member 11 is formed by being wound around the member 26 and combined with the A holding portion 11a. Then the lid body 27
to completely hold the holding member 11.
Then, the rotary shaft 23 of the rotary stake is rotated to rotate the holding member 11 while moving the rotary support member 24 toward the binding line 2. At this time, the rotation of the holding member 11 is in the direction in which the binding line 2 is wound. so that it rotates in the opposite direction. In this way, if the holding member 11 is rotated over the electric wire 1 and brought closer to the binding wire 2, at a certain point the end 2a of the binding wire 2 will be attached to the holding member 11 as shown in FIG. It locks onto a protrusion 17 in the large diameter hole 13. If the rotation of the holding member 11 is continued thereafter, the binding wire 2 will gradually loosen from its end 2a.

In this embodiment, the large-diameter holes 13 and 14 are formed from both end faces of the holding member 11, so that the electric wire 1 can be locked from either the left or right side.

(Effects of the invention) According to this invention, it is possible to loosen the bound wire that is tightly wrapped around the electric wire very easily, and the blade of the cutter tool when cutting the bound wire can be easily inserted between the bound wire and the electric wire. can do. Therefore, it is possible to easily and quickly cut the binding wire. Moreover, the above-mentioned series of operations for loosening the binding wires can be performed safely, and the practical effects thereof are high.
