DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a structure of a binding wire processing tool that can be used when a ground-operated robot replaces insulators or the like under a live line in a high-voltage distribution line.

[0002]

When a preform bind line (hereinafter simply referred to as a bind line) is detached and attached by remote control by a ground-operated robot, an electric wire for attaching a driver and a bind line processing tool is used. Because of the long distance, there has been a long-awaited desire to develop a binding wire processing tool having a structure that can be processed with as simple a work procedure as possible. In view of this desire, the present invention aims at solving the following problems. Facilitates attachment of the bind wire processor to electric wires. The binding wire can be wound and removed without moving the binding wire processor along the electric wire, that is, in a stationary state. Even if the rotation control of the bind line processor is rough, no problem is caused.

[0003]

A binding wire processing tool according to the present invention has a notch-equipped rotating holder fixed to one end of a notched plate-shaped positioning plate and a notched wire guide. A support base having a taper is protruded outward from the electric wire guide, and an L-shaped winding torsion lever is fixed to the support base to face the tip of the torsion lever. A support base protrudes from the positioning plate at a position to be fixed, an arc-shaped expanding guide is fixed to the support base, and a winding-end pressing pin is fixed to the bottom of the winding torsion lever. At the other end of the rotary holder, another positioning plate provided with a notch and another wire guide provided with a notch are fixed, and a support base is protruded from the wire guide. The detachable torsion lever provided with a hook for unraveling the binding wire is fixed, and the rotary holder is provided. The by reverse rotation, the rotary holder - is characterized in that it is configured to stop the opening position.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described with reference to the drawings. A binding line processing tool according to the present invention is, as shown in FIGS. -1, a plate-shaped positioning plate 2 having a notch and a wire guide 3 having a notch are fixed, and a support table 5 having a taper 4 is protruded from the wire guide 3; An L-shaped winding torsion lever 6 is fixed to the support table 5, and a support table 8 is protruded from the positioning plate 2 at a position facing the tip 7 of the torsion lever 6. An arc-shaped diameter-enlarging guide 9 is fixed to the support table 8, a winding-end pressing pin 10 is fixed to the bottom of the winding torsion lever 6, and a notch is provided at the other end of the rotary holder-1. The positioning plate 11 and the notched wire guide 12 are fixed. Projecting and this support base 13, remove twist lever having a raised claw 14 solves binding wire to the tip -
15 is fixed. The end-of-winding pressing pin 10 provided at the bottom of the winding torsion lever 6 is separated from the positioning plate 2 by a distance corresponding to about 1/2 pitch from the end of the binding wire to be wound. When the binding wire is attached, the leading end of the end-of-winding pressing pin 10 is spaced from the outer surface of the binding wire by a distance substantially corresponding to the outer diameter of the binding wire.

[0005] As shown in FIG. 3, a groove 16 is provided at the edge of the rotary holder 1, and a spring 17 is provided in the groove 16.
The tip of the claw 18 to which the pressing force is applied is dropped, and when the tip of the claw 18 is stationary in the groove 16, the rotary holder 1 can be stopped at the opening position where the electric wire can be attached and detached. Has become. As can be seen from FIG.
When the rotation holder-1 rotates clockwise, the claw 18
Is detached from the groove 16 without resistance, and does not hinder the rotation of the rotary holder 1. However, when the rotary holder 1 rotates counterclockwise and the claw 10 falls into the groove 16, the rotation of the rotary holder 1 is stopped. Acts as a stopper.

[0006] The rotating holder-1 is a driving bevel gear 1
9, a well-known gear mechanism including a driven bevel gear 20, driven spur gears 21 and 21 ', and an idle gear 22 can rotate clockwise or counterclockwise regardless of the notch.

First, the winding operation will be described. As shown in FIG. 4, a binding wire 23 (preformed so as to be wound clockwise in Japanese standards) is shown in FIG.
It is set, the end of the bind wire 23 on the right side of the insulator 24 is gripped by the gripper 25 of the robot, and the binding wire processing tool of the present invention is mounted on the electric wire 26. In FIG. To rotate the rotation holder-1 clockwise. Then, as shown in FIG. 5, the diameter increasing guide 9 increases the turning radius of the bind wire 23,
When the bind wire 23 reaches the upper part of the torsion lever 6, the torsion lever 6 twists the bind wire 23 and winds the bind wire 23 around the electric wire 26. When twisted by the winding pitch of the bind wire 23, the wire end of the bind wire 23 is almost 1 /
Two pitches (corresponding to the ridges) are pressed by the end-of-winding pressing pins 10. This completes the work of winding the bind wire on the left side of the insulator 24. In addition, since the tip of the end-of-winding press pin 10 has a distance from the outer surface of the bind wire 23 that is substantially equal to the outer diameter of the bind wire 23, after the work is completed, the rotary holder -1 is continuously rotated. In addition, since only the idle rotation does not cause a trouble such as damaging the bind wire 23, rough rotation control is possible. When the work is completed, the rotating holder-1 is rotated in the reverse direction,
The tip of the claw 18 is dropped into the groove 16 of the rotary holder 1, the rotary holder 1 is stopped at the opening position, and the binding wire processing tool is removed from the electric wire 23. Next, when winding the bind wire 23 on the right side of the insulator 24, the bind wire processing tool is turned over, and the tool is mounted on the right electric wire 26, and then the same operation as described above may be repeated.

Next, the removal operation will be described with reference to FIG.
When the binding wire processing tool is mounted on the electric wire 26 and the rotary holder-1 is rotated clockwise as shown in FIG. 2, the detachment twist lever 15 rotates leftward toward the wire end of the binding wire 23, and the binding wire is rotated. The unraveling pawl 14 is hooked on the bind wire 23, and the bind wire 23 is released from the electric wire 26. Since the binding wire 23 has a strong stiffness, if the inside is twisted about 10 cm from the wire end, the insulator 24 can be easily unscrewed. Further, even if the detachment twisting lever 15 is turned too much, there is no operational problem because the wire end of the binding wire 23 escapes.
When the work of unwinding the binding wire 23 up to the insulator 24 is completed, the rotary holder-1 is rotated in the reverse direction, stopped at the opening position, and the binding wire processing tool is turned over as in the case of the winding work, and After attaching to the left electric wire 26, the same operation as described above may be repeated.

Therefore, the tool for processing the binding wire is stationary in both the winding and removing operations of the binding wire, and the rotating direction of the rotary holder 1 is always clockwise. The operation can be very simple.

[0010]

As described above, the present invention has the following advantages. Since the opening of the binding wire processing tool can be stopped at a fixed position, the attachment to the electric wire is easy. The bind line can be attached and detached while the bind line processor is stationary. There is no problem even if the rotation control of the bind wire processor is rough.
