And the operation part 9 which consists of a ring part is integrally formed with the said wire part 5 in the longitudinal direction both ends of the wire part 5. As shown in FIG. As described above, the operation portion 9 has an annular shape into which the movable side locking portion 10 and the fixed side locking portion 11 of the wire binding operation tool 1 can be inserted, and the operation portions 9 are opened to each other. Thus, the opening 7 of the storage and clamping unit 6 can be opened.

  FIG. 6 is an explanatory view of another example of the wire binding tool 3 used in the present embodiment, where (a) is a plan view and (b) is a front view. The wire binding tool 3 of this embodiment is suitable for binding a high-voltage distribution line 31 and a high-voltage branching line 32 arranged side by side (horizontal direction), for example, as shown in FIG. Similarly to the wire binding tool of FIG. 4, the wire binding tool 3 is also formed by bending a spring metal wire that can be elastically deformed and restored after elastic deformation. The cross-sectional shape of the wire portion 5 is a circle or a rectangle, and is insulated and coated by a vapor deposition method or the like. Further, as shown in FIG. 6 (b), the wire portion 5 includes a storage pinching portion 6 that stores, for example, the high-voltage distribution wires 31 and the high-voltage branch wires 32 arranged side by side as they are.

  A part of the peripheral edge portion of the storage sandwiching portion 6 corresponds to both ends in the longitudinal direction of the spring metal wire constituting the wire portion 5, and an opening for opening and closing the storage sandwiching portion 6 is provided between the both ends. 7 is formed. In addition, the wire portion 5 is also formed with a winding portion 8 that is formed by bending the spring metal wire continuously from the storage sandwiching portion 6. For example, as shown in FIG. 7, the winding portion 8 functions as a spring portion that automatically closes the opening 7 when the opening 7 of the storage and clamping portion 6 is opened. And the operation part 9 which consists of a ring part is integrally formed with the said wire part 5 similarly to the electric wire binding tool of the said FIG.

Insert into the annular part of the operation part 9. In this state, when the operation handle 15 is rotated in a preset direction and the telescopic shaft 12 is extended, the operation portions 9 are separated from each other, and accordingly, the storage holding portion formed in the wire binding device 3 6 opening 7 opens. At this time, the winding part 8 functions as a spring part that automatically closes the opening 7 of the storage and clamping part 6. In this state, the high-voltage distribution line 31 and the high-voltage branch line 32 are housed in the storage and holding part 6. After that, when the operation handle 15 is rotated in the reverse direction and the telescopic shaft 12 is contracted, the operation parts 9 are connected to each other. Approach each other. At that time, since the winding part 8 functions as a spring part that automatically closes the opening part 7 of the storage and clamping part 6, when the opening part 7 is closed to the extent that the operating parts 9 come into contact with each other, the storage and clamping part 6 Thus, the high-voltage distribution line 31 and the high-voltage branch line 32 are sandwiched and bound together. When the high-voltage distribution line 31 and the high-voltage branch line 32 are clamped by the storage clamping unit 6, the movable side locking unit 10 and the fixed side locking unit 11 of the wire binding operation tool 1 are pulled out from the annular operation unit 9.

  The bundling work between the high-voltage distribution line 31 and the high-voltage branch line 32 is performed by an operator riding on a bucket 34 of an aerial work vehicle 33, for example, as shown in FIG. In the wire binding operation tool 1 of the present embodiment, the operation handle 15 of the wire binding operation tool 1 is only rotated when the high-voltage distribution line 31 and the high-voltage branching cable 32 are bound. No one hits the edge of the bucket 34. Therefore, the workability of wire bundling work is good and the work load is small. On the other hand, in the conventional wire bundling operation, as shown in FIG. 11, a bundling wire 101 generally coated with aluminum, called vinyl-coated aluminum binding, which has a surplus grip length, is used as the high-voltage distribution line 31 and high-voltage branch line 32. Wrap. The two ends of the binding wire 101 are gripped by two hands with one hand holding the gripping tool 102 such as an insulating barb, and the excess length of the grip is cut and the twisted ends are bound. It is bent to the side. In this operation, when twisting the both ends of the binding wire 101, it is difficult to change the holding tool 102 of both hands, so the operator himself holding the holding tool 102 with both hands in the bucket 34 in the direction of the arrow in the figure. Rotate. At this time, the balance may be lost due to rotation, and the gripping tool 102 may come into contact with the bucket 34 or the gripping may be lost. Since the two gripping tools 102 are operated by one person, the work is difficult and the work load is large.

  As described above, in the wire binding operation tool of the present embodiment, the wire binding tool 3 for binding the high-voltage distribution line 31 and the high-voltage branch line 32 is formed by bending the spring metal wire, A storage and holding portion 6 for storing and holding the high-voltage branch wire 32, an opening 7 for opening and closing the storage and holding portion 6, and an annular operation portion 9 integrally formed on both sides of the opening 7.

The movable side locking portion 10 attached to the distal end portion of the telescopic shaft 12 in the expansion / contraction direction is inserted into one of the annular operation portions 9 of the electric wire binding device 3 while being inserted into one annular operation portion 9. In this state, when the telescopic shaft 12 is extended in the longitudinal direction of the bar part 2 with respect to the bar part 2, the fixed side locking part 11 and the movable side locking part 10 are separated from each other. As a result, the operation parts 9 of the wire binding tool 3 are separated from each other, and the opening part 7 of the storage and holding part 6 is opened, so that the high-voltage distribution line 31 and the high-voltage branch wire 32 are placed in the storage and holding part 6 of the wire binding tool 3. Store. Thereafter, when the telescopic shaft 12 is contracted in the longitudinal direction of the bar part 2 with respect to the bar part 2, the fixed side locking part 11 and the movable side locking part 10 come close to each other, and the electric wire binding tool 3 is held and sandwiched. The opening 7 of the part 6 is closed, and the high-voltage distribution line 31 and the high-voltage branch line 32 are sandwiched between the storage and sandwiching parts 6. At this time, the worker holding the wire binding operation tool 1 does not need to rotate in the bucket 34 of the aerial work vehicle 33, for example. Therefore, the workability of the wire bundling work can be improved and the work load can be reduced.

  Next, a second embodiment of the wire bundling operation tool of the present invention will be described with reference to the drawings. FIG. 8 is an overall view showing the wire bundling operation tool of the present embodiment, and FIG. 9 is a detailed view of an upper end portion of the wire bundling operation tool of FIG. The wire binding operation tool 1 is made of, for example, an insulating bark and has a bar portion 2 that is long in the vertical direction as a gripping portion that an operator grips. A fixing claw portion 17 as a fixing portion protrudes upward from the upper end portion of the bar portion 2 in the figure. On the other hand, a movable claw portion 18 as a movable portion that can rotate in the left-right direction in the drawing is also formed on the upper end portion of the bar portion 2 in the figure so as to protrude upward. The movable claw portion 18 is disposed so as to face the fixed claw portion 17 and is attached to the upper end portion of the bar portion 2 through the movable pin 21 so as to be rotatable in the left-right direction in the figure. The movable claw portion 18 is connected to the operation handle 20 via a link arm 19, and a link structure is formed by the link arm 19, the operation handle 20, and the movable claw portion 18. Therefore, when the operation handle 20 is rotated in the direction of arrow a, the movable claw portion 18 opens in the direction of arrow b. The fixed claw portion 17 is formed with a fixed side locking portion 11 protruding laterally (horizontal direction) at the distal end portion thereof, and the movable claw portion 18 also has the same lateral direction (horizontal direction) as the fixed side locking portion 11. The movable side latching | locking part 10 is protrudingly formed. As a result, the movable side locking portion 10 and the fixed side locking portion 11 protrude in the same lateral direction and are disposed opposite to each other on the left and right. The movable side locking portion 10 and the fixed side locking portion 11 have a pin shape that can be inserted into the annular operation portion 9 of the wire binding tool 3 described above. The flange portion may be formed so that the operation portion 9 does not come off. In addition, the electric wire binding operation tool 1 of the present embodiment may be configured such that an attachment is attached to an existing insulation barely, or the whole may be newly created.

Further, the fixed side locking portion 11 at the tip end of the fixed claw portion 17 is inserted into one of the annular operation portions 9 of the wire binding device 3 in FIG. 4, and the movable side locking portion at the tip end of the movable claw portion 18 is inserted. 10 is inserted into the annular part of the other operation part 9 of the wire binding tool 3 of FIG. When the operation handle 20 is rotated in the direction of arrow a in FIG. 8 in this state, the operation parts 9 of the electric wire binding tool 3 are separated from each other as the fixed claw part 17 and the movable claw part 18 are separated. Along with this, the opening 7 of the storing and holding part 6 formed in the wire binding tool 3 is opened. At this time, the winding part 8 functions as a spring part that automatically closes the opening 7 of the storage and clamping part 6. In this state, the high-voltage distribution line 31 and the high-voltage branch line 32 are housed in the storage and clamping unit 6, and then the operation handle 20 is rotated in the reverse direction to close the fixed claw portion 17 and the movable claw portion 18.

In that case, since the winding part 8 functions as a spring part which automatically closes the opening part 7 of the accommodation clamping part 6, if the opening part 7 is closed to such an extent that the operation parts 9 of the wire binding tool 3 contact each other. The high voltage distribution line 31 and the high voltage branch line 32 are clamped by the storage clamping unit 6 and are bound together. When the high voltage distribution line 31 and the high voltage branch line 32 are clamped by the storage clamping unit 6, the movable side locking unit 10 and the fixed side locking unit 11 of the wire binding operation tool 1 are pulled out from the annular operation unit 9.

  For example, as shown in FIG. 10, the bundling operation between the high-voltage distribution line 31 and the high-voltage branch line 32 is performed by an operator on the bucket 34 of the aerial work vehicle 33. In the wire binding operation tool 1 of the present embodiment, when the high-voltage distribution line 31 and the high-voltage branching cable 32 are bundled, the operation handle 20 of the wire binding operation tool 1 is simply rotated in the direction of arrow c in FIG. Therefore, the wire binding operation tool 1 does not hit the edge of the bucket 34. Therefore, the workability of wire bundling work is good and the work load is small. On the other hand, in the conventional wire bundling work, as described above, when the operator himself holding the gripping tool 102 with both hands rotates in the bucket 34, the balance is lost due to the rotation and the gripping tool 102 is moved to the bucket 34. There are cases where contact or gripping may occur, and the two gripping tools 102 are operated by one person, so that the work is difficult and the work load is large.

The movable side locking portion 10 of the movable claw portion 18 facing the fixed claw portion 17 is inserted into one of the annular operation portions 9 of the binding device 3 and the other annular operation of the wire binding device 3 is operated. Plug into part 9. In this state, when the movable claw portion 18 is opened in the opening / closing direction with respect to the fixed claw portion 17, the fixed side locking portion 11 and the movable side locking portion 10 are separated from each other. As a result, the operation parts 9 of the wire binding tool 3 are separated from each other, and the opening part 7 of the storage and holding part 6 is opened. Store. After that, when the movable claw portion 18 is closed in the opening / closing direction with respect to the fixed claw portion 17, the fixed side locking portion 11 and the movable side locking portion 10 come close to each other, and the opening of the storage clamping portion 6 of the wire binding device 3 is opened. The part 7 is closed, and the high-voltage distribution line 31 and the high-voltage branch line 32 are clamped by the storage and clamping unit 6. At this time, the worker holding the wire binding operation tool 1 does not need to rotate in the bucket 34 of the aerial work vehicle 33, for example. Therefore, the workability of the wire bundling work can be improved and the work load can be reduced.

  Further, the movable claw portion 18 is opened and closed in the opening and closing direction by the link structure of the operation handle 20 provided at the other end portion in the longitudinal direction of the bar portion 2 and the link arm 19 arranged in parallel or substantially parallel to the bar portion 2. .
