  In the conventional apparatus, when it becomes necessary to add another transformer, the upper and lower support brackets are attached to the existing upper and lower band bodies by new band bodies for adding transformers. It is enough to mount and support the new transformer on the support bracket, but due to the vertical displacement of the old and new band bodies, the figure where the pair of old and new transformers are mounted on the power pole in a different way In order to make it preferable, that is, in order to obtain a columnar state in which a pair of transformers are located at almost the same height, once the existing one is removed, the common platform is used for both. It is necessary to mount it on the top (transformer column method).

  The present invention pays attention to the disadvantages of the conventional example, and can add a new pole transformer to an existing pole transformer mounted by a so-called direct mounting pillar method, The present invention has been devised for the purpose of providing a columnar device that can be arranged in substantially the same degree as existing ones and can obtain a columnar state that does not impair the appearance.

  In the columnar transformer mounting device, the upper support bracket is fastened to the power pole by the upper band body, and the lower support bracket is fastened to the utility pole by the lower band body, and the pole transformer is supported by the upper support bracket and the lower support bracket. The upper mounting band body that is positioned above the upper band body and fastened to the power pole, and the lower mounting band body that is positioned below the lower band body and tightened to the power pole are provided with projecting support pieces. Adjusting holes are arranged along the longitudinal direction on the vertical arm, which is fixed to the support piece, and the bolts and nuts screwed into the bolts are aligned with the appropriate adjusting holes. The upper support frame attached to the vertical arm is arranged at the same height as the upper support bracket and the lower support frame, respectively, and protrudes into the pole transformer newly added to the upper support frame. The upper retaining frame is installed on the lower support frame. Is of a structure in which are supported, respectively.

  Since the present invention is configured as described above, a new pole transformer is added without being interfered with the existing pole transformer and the mounting device such as a band body equipped with the pole transformer. It is possible to mount the pillars, and since the old and new pole transformers can obtain the state of the pillars existing at almost the same height, the appearance is good and suitable.
