Description

  TECHNICAL FIELD The present invention relates to a gold wheel mounting tool for mounting a gold wheel used when extending an overhead wire to a steel tower. The present invention also relates to a method for extending an overhead line between the steel towers.

  Conventionally, when an overhead wire such as an overhead ground wire or an overhead electric wire is extended between steel towers, a gold wheel attached to the steel tower is used. And a gold wheel fixture is known as what attaches such a gold wheel to a steel tower (for example, patent documents 1). And an overhead line is extended (constructed) between each steel tower by being drawn over each gold wheel.

Japanese Utility Model Publication No. 3-120618

  Here, the tower is a tower main body composed of a plurality of main pillar materials extending to the upper end along the vertical direction, a horizontal material for connecting the main pillar materials, and the like, and is projected from the tower main body in the lateral direction. And a bracelet for supporting. The arm metal is composed of an arm metal main material disposed along the horizontal direction, an arm metal support material that supports the arm metal main material from the lower side, and the like.

  And in the money wheel fixture concerning patent documents 1, the fixture main part connected to a money wheel is being fixed to the brace main material. Thereby, when an overhead wire is drawn, the vertical load of the fixture main body generated via the gold wheel is received by the arm metal main member arranged along the horizontal direction. Therefore, the steel tower may have to be reinforced in order to prevent deformation of the brace main material.

  Therefore, in view of such circumstances, the present invention provides a metal wheel mounting tool and an overhead wire that can minimize reinforcement to the steel tower when the overhead wire is extended using a metal wheel attached to the steel tower. It is an object of the present invention to provide a wire drawing method.

  The gold wheel mounting tool according to the present invention is a gold wheel mounting tool for mounting a gold wheel used when extending an overhead wire to a steel tower including a plurality of main pillars extending to the upper end along the vertical direction. A fixture body connected to a car is provided, and the fixture body has a lower end fixed to an upper end portion of the main pillar material and supported in a longitudinal direction from directly above the main pillar material so as to be supported by the main pillar material. It is characterized by comprising a longitudinal member to be arranged.

  According to the gold wheel fixture according to the present invention, the vertical member is provided on the fixture main body connected to the gold wheel. And while the lower end part of a vertical member is fixed to the upper end part of the main pillar material of a steel tower, the vertical member is arrange | positioned along the vertical direction from right above the main pillar material. As a result, since the fixture body is supported by the main pillar material via the vertical member, the vertical load of the fixture main body generated via the gold wheel is the main pillar material arranged along the vertical direction. Will receive.

  Moreover, in the money wheel mounting tool according to the present invention, a plurality of vertical members may be provided, and a connecting member that connects the vertical members may be provided.

  According to the gold wheel mounting tool having such a configuration, the connecting members connect the plurality of vertical members provided together. Thereby, each vertical member arrange | positioned along a vertical direction from right above a main pillar material is supported in a horizontal direction by a connection material and another vertical member.

  Moreover, in the metal wheel mounting tool according to the present invention, the connecting member may be configured such that the length can be changed so that the distance between the vertical members can be changed.

  According to the metal wheel mounting tool having such a configuration, since the length of the connecting material can be changed, the distance between the longitudinal members can be changed by changing the length of the connecting material. Thereby, it can respond flexibly also to the steel tower of various shapes, specifically, the steel tower from which the distance between main pillar materials differs.

  The overhead wire extending method according to the present invention is a method of installing an overhead wheel between steel towers by attaching a gold wheel to a steel tower provided with a plurality of main pillars extending in the vertical direction to the upper end, and passing the overhead wire over the gold wheel. In the method of extending the overhead wire to extend the wire, the gold wheel is attached to the steel tower via the gold wheel attachment, and the gold wheel attachment includes an attachment main body connected to the gold wheel, and the attachment main body. Is provided with a vertical member that is fixed to the upper end portion of the main column member and arranged along the vertical direction from directly above the main column member so as to be supported by the main column member.

  According to the method for extending an overhead wire according to the present invention, a vertical member is provided on the fixture body connected to the gold wheel. And while the lower end part of a vertical member is fixed to the upper end part of the main pillar material of a steel tower, the vertical member is arrange | positioned along the vertical direction from right above the main pillar material. As a result, since the fixture body is supported by the main pillar material via the vertical member, the vertical load of the fixture main body generated via the gold wheel is the main pillar material arranged along the vertical direction. Will receive.

  As described above, according to the metal wheel mounting tool and the overhead wire extending method according to the present invention, the longitudinal load of the mounting tool body generated through the metal wheel is arranged along the vertical direction.
