DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to the structure of a "-" winding tool used when connecting a high-voltage distribution line and the primary side of a pole transformer with a high-voltage pull-down line.

[0002]

Conventionally, when connecting the high voltage distribution line and the primary side of the pole transformer by means of a high voltage down line, a branch sleeve is attached to one end of the high voltage down line, and the branch sleeve is attached. And the other end of the high-voltage drop line was connected to the primary side of the pole transformer. At that time, vibrations due to wind pressure, etc. are concentrated on the branch sleeve, and in order to prevent an accident of disconnection of the high-pressure pull-down line at the branch sleeve,
The high-voltage down-line was wound around the high-voltage distribution line in the shape of a “no”. (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-voltage downpipe branch line. −
The other worker sandwiches the high-pressure drop line at a position appropriately separated from the branch sleeve by an insulating screw, and assists the high-pressure drop line to prevent it from moving. The operator, while operating the insulation yoke,
It was carried out in the procedure of winding in the shape of a "no" around a high-voltage distribution line. Therefore, in addition to the usual two-person operation, there is a disadvantage that the operation time is long and the burden on the operator is large. SUMMARY OF THE INVENTION The present invention has been made in order to solve the above-mentioned drawbacks, and an object of the present invention is to provide a "no" character winding tool capable of easily performing the "no" character method by one person.

[0003]

According to a first aspect of the present invention, there is provided a tool for wrapping a "-" character having a main body frame formed in a U-shape, a flexible portion provided at a tip end thereof, and the main body frame being bent. A connecting bracket for connecting to an insulating operation rod or the like is provided at a base of the frame, and a support base for supporting electric wires is provided at appropriate intervals in the main body frame. is there.

[0004]

DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described with reference to the drawings. In FIG. 1, reference numeral 1 denotes a main body frame made of stainless steel or the like, and has a substantially U-shape as shown in the drawing. It is molded into. At the tip of the body frame 1,
A flexible portion 2 that can be bent is provided. In addition,
The flexible portion 2 can be realized by inserting a commercially available flexible tube or the like into the distal end portion of the main body frame 1 and mounting it.

[0005] At the base of the main body frame 1 is provided a connecting fitting 3 for connecting to the insulating operating rod 6 or the like. The insulating operating rod 6 is fitted to the connecting fitting 3 and an operator rotates the insulating operating rod 6. Then, the main body frame 1 rotates in conjunction with the rotation. In addition, as shown in FIG.
Are provided with support stands 4 at appropriate intervals for supporting electric wires. For example, as shown in FIG. 2, the support 4 has a structure in which a mounting hole 7 for electric wires can be formed, and the electric wires can be easily attached to and detached from the mounting hole 7.

Further, the top of the main body frame 1 is
As shown in FIG. 1, a gripper-grip 5 is provided.

In practice, as shown in FIG. 3, the high-pressure pull-down line 8 to which the branch sleeve 9 is attached is located on the flexible portion 2 side, and the high-pressure pull-down line 8 is mounted on the support base 4. Then, the flexible portion 2 is bent as shown in FIG.

[0008] The insulating operating rod 6 is fitted into the connecting fitting 3 and the insulating operating rod 6 is operated or the gripper-grasping portion 5 is sandwiched by an insulating yoke (not shown), and as shown in FIG. System 1 is hooked on the high-voltage distribution line 10. At this time, the other end of the high voltage pull-down line 8 is already connected to the primary side of the pole transformer.

Next, when the insulating operating rod 6 is rotated, the high-voltage pulling line 8 on the branch sleeve 9 moves and is wound around the high-voltage pulling line 8 from the pole transformer. , Sandwich the branch sleeve 9 part, pull it forward, and then grip the gripper gripping part 5 with an insulating cap.
When the system 1 is lifted upward, the high-pressure reduction line 8
, The main body frame 1 is pulled out, and as shown in FIG.

[0010]

Since the present invention is constructed as described above, it has an effect that the "no" character construction method can be carried out easily and quickly by one person. Further, since the structure is simple, mass production can be performed at low cost.
