Description

[Detailed description of the invention] [Industrial application field] This invention relates to a connecting pole for extending the upper end of a power transmission/distribution utility pole to erect power transmission/distribution lines and an overhead ground wire.

[Conventional technology and issues to be solved]

At the time of installation, power transmission and distribution utility poles are selected to be of a size commensurate with the amount of power to be transmitted and distributed and the expected amount of power in the future, and power transmission and distribution lines are installed on these power transmission and distribution utility poles. However, when the amount of electricity used increases and it becomes necessary to install more power transmission and distribution lines, replacing utility poles with larger ones is costly and requires power outages, which can cause inconvenience to customers. becomes.

Therefore, a connecting pole 1 as shown in FIG. 16 is used for the purpose of adding power transmission and distribution lines. The connecting pole 1 includes a connecting pole main body 2, an arm 3 for installing an overhead ground wire, and an arm 4 for installing a power transmission and distribution line, and a power transmission and distribution utility pole 5.
The connecting column main body 2 is fitted and fixed to the upper end portion of the connecting column. This conventional connecting post 1 had armrests 3 and 4 protruding from the left and right, giving it a cumbersome feel.
For this reason, in today's world where beautification of urban spaces is being advocated, the structure of the conventional connecting pillar 1 has been required to be reconsidered as it impairs the aesthetic appearance. Moreover, since the attachment of the armrests 3 and 4 to the joint post 1 involves tightening the belts fixed to the arms 3 and 4 with bolts and attaching them to the joint pole 1, the belts and bolts may stretch due to creep or the like. , there was also a risk that the tightening force would loosen.

By the way, power transmission and distribution utility poles need to be laid at approximately regular intervals, and they also need to be laid in positions that do not obstruct road traffic, so the location of power transmission and distribution utility poles is limited to a certain extent. limited and cannot be easily moved. However, when power transmission and distribution power poles are installed adjacent to buildings, or when construction work is being carried out adjacent to power poles, it is necessary to shift the installation position of power transmission and distribution lines to prevent danger. be. Therefore, conventionally, the first
As shown in FIG. 7, a rack arm 6 was protruded from the side of a power transmission and distribution utility pole 5 to separate the power transmission and distribution lines from buildings and the like.

However, such a protruding arm arm 6
It was troublesome to attach it to the connecting column main body 2, and it was aesthetically unsightly. Moreover, when a power transmission and distribution line is installed by protruding from the connecting pole 1 using the protruding rack arm 6, it is difficult to install an overhead ground wire at a predetermined position above the power transmission and distribution line. It was not possible to construct a ground wire.

[Means to solve the problem]
