DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to the structure of a pendulum type "NO" -shaped winding tool used for connecting a high voltage distribution line and the primary side of a pole transformer with a high voltage pull-down line.

[0002]

2. Description of the Related Art Conventionally, when a high voltage distribution line and the primary side of a pole transformer are connected by a high voltage down line, a branch sleeve is attached to one end of the high voltage down line, and the branch sleeve is connected to a high voltage distribution line. The other end of the high-voltage pull-down line was connected to the primary side of the pole transformer by biting the wire. At that time, vibrations due to wind pressure, etc. are concentrated on the branch sleeve, and in order to prevent the accident of disconnection of the high-voltage reduction line at the branch sleeve, the high-voltage reduction line should be replaced with the `` no '' character on the high-voltage distribution line. I was wrapping it. (Usually, this method is called the “No” character method.) Since this “No” character method is performed under hot wire, one worker must use an insulated yatco to cut the high- -The other worker interposes the high-pressure drop line at an appropriate distance from the branch sleeve section with an insulating screw, and assists the high-pressure drop line to prevent it from moving. While the sandwiched operator is operating the insulation yoke properly,
The following drawbacks were encountered because the process was performed by wrapping around the "no" character. Since the work is performed at a high place and the work is performed by two persons, the work time is lengthened and the burden on the worker is large. The work operation is too complicated and cannot be applied to the robot live line method.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described with reference to the drawings. As shown in FIGS. -The lower block guide 3 having the holding groove for the high-voltage distribution line 23 provided in the block 2 is arranged to face the lower split guide 3. The lower split guide 3 is immovable, and the movable upper split guide 1 moves up and down when gripping the high voltage distribution line 23.

The movable upper split guide 1 is connected by a slide plate 4 to a slide block 5 which is constantly pressed down by a spring force of a spring 15. Therefore, the movable upper split guide 1 is always pushed down toward the lower split guide 3 as shown in FIG. 2, and the slide block 5 is forcibly pushed upward against the spring force of the spring 15. As a result, the movable upper split guide 1 moves upward, and as shown in FIG.

An upper gripper 6 is attached to the base block 2.
The lower gripper 7 is fixed to the slide block 5 so as to face the upper gripper 6. The slide block 5 can move up and down along a support shaft 16 fixed to the base block 2.
Therefore, when the upper gripper 6 and the lower gripper 7 are sandwiched by the manipulator, the upper gripper 6 of the base block 2 is immovable.
7, that is, the slide block 5 is forcibly moved upward against the spring force of the spring 15, and pushes up the movable upper split guide 1.

A torsion shaft 8 whose rotational force is constantly locked is attached to the base block 2, and a reversing pulley 9 is fixed to the torsion shaft 8. There are various ways to lock the rotation of the torsion shaft 8. For example, a stopper ker 17 is fixed to the torsion shaft 8, and the stopper ker 17 is fixed.
17 is received and locked by a ball plunger 18, and the stopper pallet 17 is removed from the ball plunger 18 so that the lock can be released.

One end of a substantially C-shaped torsion ring 10 is fixed to a torsion shaft 8 located at the front of the reversing pulley 9 as shown in FIG. At the lower end of the torsion ring 10, a stopper Kelle 17 is provided with a ball plunger.
18 and a starting lever 19 for unlocking the twist ring 10 is attached.

[0010] One end is fixed to the movable upper split guide 1,
As shown in FIG. 2, the wire 11 having the other end fixed to the reversing pulley 9 has a slack, and
Multiplied by nine. In FIG. 2, reference numeral 20 denotes a guide pulley. When the movable upper split guide 1 is pushed up to the top, the length of the wire 11 is as shown in FIG.
The wire 11 is adjusted so as to eliminate the slack.
In addition, if necessary, the reverse pulley 9 and the wire 11
Is omitted, and as shown in FIGS.
A gear mechanism including a combination of a wheel 24 and a worm 25 is provided, and the twist shaft 26, that is, the twist ring 10 can be rotated forward and reverse by rotating the twist grip 26. Good.

A weight 12 and a branch sleeve holder 13 are fixed to the other end of the twist ring 10. The other end of the torsion ring 10 is located almost directly above the torsion shaft 8 as shown in FIG. 2, and the weight of the weight 12 is
The starting lever 19 is slightly pushed up by a manipulator or the like, and the torsion ring 10 is slightly rotated to unlock the ball plunger 18. 10 rotates at once, as shown in FIG.
The weight is adjusted so that it can fall down to just below like a pendulum.

As shown in FIG. 1, the base block 2 protrudes from the torsion ring 10 and
In order to support the wire 2, an electric wire support rod 14 provided with a bifurcated clip at the tip is fixed.

At the time of implementation, a high pressure pull-down wire 22 is crimp-connected to the branch sleeve 21 and then mounted on the branch sleeve holder 13 as shown in FIG. It is bent into a letter and fitted to the wire support rod 14. After confirming that the torsion ring 10 is locked by the ball plunger 18, the upper gripper 6 and the lower gripper 7 are sandwiched between the manipulators, and the movable upper split guide 1 is moved upward. .

Next, the high-voltage distribution line 23 is inserted through the openings of the movable upper split guide 1 and the lower split guide 3 (FIG. 3), and the upper gripper 6 and the lower gripper 7 are released from being pinched (FIG. 4). ). Next, the starting lever 19 of the torsion ring 10 is lightly pushed up by a manipulator, and a ball plunger is used.
When the lock 18 is released, the weights of the weight 12 and the branch sleeve 21 are added, and the branch sleeve holder 13 partly straddles the high-voltage distribution line 23 around the torsion shaft 8 to be immediately below. It falls while twisting and stops as shown in FIG.

Next, the branch sleeve 21 is clamped by a manipulator, detached from the branch sleeve holder 13, and moved toward the front, and the bent high-pressure drop line 22 is provided.
Can be wound around the high-voltage distribution line 23 in the shape of "".

Next, when the branch sleeve 21 sandwiched between the manipulators is approached to a portion where the high-voltage distribution line 23 is peeled off and mounted on the high-voltage distribution line 23, the high-voltage distribution line 23 is mounted.
The work on the side is over.

Next, the high voltage pull-down line 22 is connected to the primary side of the pole transformer. Finally, the tool of the present application is connected to the high voltage distribution line 2
When the upper gripper 6 and the lower gripper 7 are detached from the manipulator, the upper gripper 6 and the lower gripper 7 are sandwiched by a manipulator.
When the weight 12 is dropped, when the weight 12 is dropped, the wire 11 that has been entangled by the reversing pulley 13 and tensed is rewound, and the twisting ring 10 is forcibly forced by the unwinding force. As shown in FIG. 3, the movable upper split guide 1 and the lower split guide 3 are opened at the same time, and the high-voltage distribution line 23 is detached from the opening.
When the torsion ring 10 returns to its original position, it is locked by the ball plunger 18, and when the gripping of the upper gripper 6 and the lower gripper 7 by the manipulator is released, the movable upper split guide 1 is released. Closes and returns to the initial position shown in FIG.

When the tool equipped with the gear mechanism is removed from the high-voltage distribution line 23, the twisting grip 26 is rotated by the manipulator to return the twisting ring 10 to its original position. Upper gripper-6 and lower gripper-7
Is sandwiched between manipulators, the movable upper split guide 1 is moved upward, and the high-voltage distribution line 23 is detached.
