Abstract

PROBLEM TO BE SOLVED: To facilitate the removal of an insulating wire protecting pipe or a protective pipe from overhead wiring by forming a driving tire which is rotated by driving force from the outside at the guide body middle part of a delta wing type joint split guide. SOLUTION: A horizontal wire pressing angle 1 is brought into contact with the upper surface of a wire 10, and a guide body 3 is fixed onto the wire 10 by a fastening tool 11. The cut line 8 of an insulating wire protecting pipe or a protective pipe 7 is then fitted in the front end of a boat form guide 2 by a tool and is guided to such a point as it engages with a driving tire 6. The driving tire 6 is rotated to pull the insulating wire protecting pipe or the protective pipe 7 into the guide body 3. When the jointing part 12 of the insulating wire protecting pipe or the protective pipe 7 engages with a delta wing type joint split guide 5, it is expanded and contracted rapidly, so that the inside of the insulating wire protecting pipe or the protective pipe 7 is contracted to such a degree as to have an original diameter while the outside of the insulating wire protecting pipe or the protective pipe 7 is opening largely, therefore, the joint is removed automatically. It is thus possible to remove the insulating wire protecting pipe or the protective pipe continuously by simple work.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for protecting an insulator at a location where an existing overhead distribution line such as a 6600-volt outdoor cross-linked polyethylene insulated wire may come into contact with a tree or a building or the like, and protect the insulator. The present invention relates to a pipe remover used to remove an insulated wire protection tube or a protection tube attached to an existing overhead distribution line in a live state in order to prevent a destruction accident, a disconnection accident, etc. beforehand. It is.

[0002]

2. Description of the Related Art Insulated wire protection tubes and protection tubes are hollow tubes made of plastic such as cross-linked polyethylene, and are provided with a single cut in the axial direction so that they can be mounted on existing overhead distribution lines. Conventionally, when removing the insulated wire protection tube and the protection tube, the insulated wire protection tube and the protection tube are sandwiched by a live wire indirect tool, such as a lance, and the cuts of the insulated wire protection tube and the protection tube are enlarged to reduce the human power. Was removed from the overhead distribution line.

[0003] Work using a hot-line indirect tool, such as a yatco, is unstable, inefficient, and requires skill. In addition, the removal work is performed on a pillar with a bad working environment. There was also a problem in terms of safety.

[0004]

SUMMARY OF THE INVENTION The present invention has been made in order to solve the drawbacks and problems described in the prior art, and is not intended to rely on hot wire indirect tools or human power, and to provide an insulated wire protective tube or protective tube. It is an object of the present invention to provide a pipe remover that can easily remove the above-mentioned components from an overhead distribution line.

[0005]

According to the pipe remover of the present invention, a horizontal wire holding angle is provided at an upper part, and a cut end of the insulated wire protection pipe or the protection pipe is formed at a tip of the angle to extend the cut. Attach the boat-shaped guide of
A guide rod that is inclined at the same angle as the above-mentioned inclination is provided at the rear end of the lower end of the guide body with an inclined lower end, and the cut of the insulated wire protection pipe or the protection pipe is rapidly expanded and contracted on the rear end upper surface of the guide rod. Provide a triangular wing type joint division guide to make
A drive tire is provided at the center of the guide body, which is pressed against the lower end of the guide body and is rotated by a driving force from the outside.

[0006]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Referring to the drawings showing an embodiment of the present invention, a horizontal wire holding angle 1 is provided at an upper part as shown in FIGS. The boat-shaped guide 2 for entering the cut 8 of the insulated wire protection pipe or protection pipe 7 at the tip of
At the rear of the lower end of the guide body 3 whose lower end is inclined, a guide rod 4 inclined at the same angle as the above-mentioned inclination is provided.
An insulated wire protection tube or a protection tube 7
A triangular wing-shaped joint division guide 5 for rapidly expanding and contracting the notch 8 is provided, and a driving tire which is pressed against the lower end of the guide main body 3 at the center of the guide main body 3 and is rotated by an external driving force. 6 is provided. FIG. 4 is an enlarged cross-sectional view taken along the dotted line in FIG.

In operation, the angle 1 is brought into contact with the upper surface of the electric wire 10, and the guide body 3 is fastened by the fastener 11.
Is fixed to the electric wire 10, and as shown by the double dotted line in FIG. 1, first, the cut 8 of the insulated electric wire protection tube or the protection tube 7 is fitted to the tip of the boat-shaped guide 2 by using a tool such as a yat and the driving tire 6. Guide to where it takes. Thereafter, the drive tire 6 is rotated by a hydraulic motor (not shown) or the like, and the insulated wire protection tube or protection tube 7 is drawn into the guide body 3 so that the insulated wire protection tube or protection tube 7 can be continuously removed. it can. At this time, when the joint portion 12 of the insulated wire protection tube or the protection tube 7 is engaged with the triangular wing-shaped joint division guide 5, it is rapidly expanded and contracted, so that the outer insulated wire protection tube or the protection tube 7 is greatly opened. During this time, the inner insulated wire protection tube or protection tube 7 contracts to almost its original outer diameter, so that the joint is automatically disconnected.

[0008]

[Effect] Since the present invention is configured as described above,
The existing insulated wire protection tube or protection tube attached to the overhead distribution line can be continuously removed by a simple operation of simply rotating the driving tire, and the joint can be removed at the same time.
