Description

  The present invention relates to a tip tool for an insulating operation rod and a branch wire winding method for winding a branch line branched from a trunk line around the trunk line.

  A branch line such as a pull-down line that branches from a trunk line such as a distribution line installed on a steel tower or utility pole, the primary side (one end side) is electrically connected to the conductor of the trunk line by a connector such as a compression sleeve, and the secondary line It arrange | positions so that the side may extend in the crossing direction with respect to the trunk line.

  And when the branch line connected to the main line is arranged so as to extend in the crossing direction with respect to the main line as it is from the connector, a force acts in a direction crossing the axial direction with respect to the branch line due to the influence of wind or the like. In addition, for the reason that the branch line may fall off the main line (connector), the branch line is wound around the main line, and one end of the branch line is electrically connected to the main line via the connector. To connect to.

  That is, in the operation of branching the branch line from the main line, the primary side of the branch line wound around the main line is wound around the secondary side of the branch line extending in the crossing direction with respect to the main line in order to support the branch line on the main line. In this way, the primary side of the branch line is electrically connected to the main line.

  And the operation | work which branches a branch line from a trunk line as mentioned above is performed by the indirect hot wire operation | work which uses an insulation operation stick | rod, an insulation jacket, etc. from a viewpoint of an electric shock accident prevention. Such work is generally performed by two people. That is, when branching a branch line from the main line, the branch line arranged so that one worker intersects the main line is sandwiched between the main line and the insulating yarn, and the state is maintained. By gripping the primary side of the branch line and operating the insulating Yatco, the branch line is wound around the trunk line so as to follow the trunk line.

  By the way, the operation of branching the branch line from the main line is a troublesome work that must be done by two people using the insulating Yatco as described above, and the main line is not subjected to the operation of winding the branch line by the insulating Yatco. On the other hand, a winding tool capable of winding a branch line is provided (for example, see Patent Document 1).

  In such a winding tool, a flexible portion is provided at the front end portion of a main body frame formed in a U-shape, and a connecting metal fitting connected to an insulating operation rod is attached to a base portion of the main body frame. The winding tool is provided with a plurality of support bases for supporting the branch lines with an appropriate interval in the longitudinal direction of the main body frame, and a gripper gripping portion for holding the insulating frame at the top of the main body frame is provided. It has been.

In the winding tool having the above configuration, the branch line along the U-shaped main body frame is supported on each support base, and then the flexible part is bent outward and the branch line along the flexible part is outward. The main body frame is hooked on the main line. The winding tool rotates the insulating operation rod around its axis while the main body frame is hooked on the main line, and grips the gripper gripping part with a jar and pulls up the main body frame, thereby branching from the support part. And the branch line is wound around the main line.

  However, as described above, the winding tool having the above-described configuration has to perform the work of bringing the branch line along the main body frame and the work of supporting the branch line by a plurality of support bases until the branch line is wound around the trunk line. The previous work is complicated, and the work load on the worker is inevitably increased.

  Further, in addition to operating the insulating operation rod while the main body frame is hooked on the main line, it is difficult for one operator to grip and lift the gripper gripping portion with the insulating jacket. That is, while the work on the insulating operation rod is performed below the trunk line, the gripping and lifting work of the gripper gripping part by the insulation jacket is a work performed above the trunk line. It is difficult to do by a person.

  Furthermore, the winding tool having the above configuration simply needs to twist the branch line hooked on the main line, and later requires work to make the primary side of the branch line along the main line or to correct the winding state on the main line. As a result, there is a problem that the work load on the worker is likely to increase.
