Description

[Detailed description of the invention] [Field of industrial application] This invention relates to a fixing device for a transformer installed on a utility pole.

[Conventional technology and its problems]

Conventionally, to install a transformer on a utility pole, the transformer is placed inside a rectangular rectangular frame, placed on the protrusion at the bottom of the rectangular frame, and suspended from the hook at the top. This is done by supporting a square frame and attaching the square frame to a utility pole with a band.

However, with this hanging type, there is a risk that the hook may come off and the transformer may fall due to vertical movement such as an earthquake.

Therefore, the purpose of this invention is to take the above points into consideration and to enable the transformer to be attached directly to a utility pole.

[Means to solve the problem]

In order to achieve the above object, in this invention, a fixing metal fitting is composed of a metal pole, a transformer metal, and a connecting bolt. The two fittings have a U-shape, and one of the fittings is made to curve the plate between the two opposing plates into a gentle arc to abut against the utility pole, while the other fitting is used to contact the utility pole between the two opposing plates. A metal band is fixed across the tip of the plate part, and the band is curved into a gentle arc to contact the transformer, and both U-shaped bodies have multistage bolt holes that can communicate with the opposing plate parts. The connecting bolts are two pairs, left and right, each with a hook at the tip, and a nut is screwed into the end that passes through the hole, and the transformer is mounted on a pedestal supported by a utility pole. A wire was wound around the transformer and the utility pole, and the hook was hooked onto the wire.

[Effect]

In the fixing device according to this invention, which is constructed as described above, first, a transformer is placed on a pedestal, a fixing metal fitting is inserted between the transformer and the utility pole, and both of the metal fittings are placed between the utility pole and the transformer. Connect and fix with connecting bolts at the mating position according to the spacing dimension, place one pad on the utility pole and the other pad on the body of the transformer, then wrap the wire between the utility pole and the transformer. At the same time, when wrapping the wire, hook the wire onto the hook of the bolt and attach the transformer to the utility pole. At this time, tightening the nut onto the bolt will increase the tension in the wire.

〔Example〕

In the figure, 1 is a utility pole, 2 is a transformer, 3 is a transformer pedestal, and 4 and 5 are bands for fixing an arm 6 that supports the transformer pedestal to the utility pole.

Reference numeral 7 designates a transformer fixing metal fitting interposed between the transformer 2 placed on the transformer pedestal 3 and the utility pole 1. As shown in an enlarged and exploded view in FIG. It consists of a metal A, a metal fitting B for the transformer, and a bolt C that connects both the metal fittings A and B.

The pad A is a band bent into a U-shape, and the U-shaped body 10 has a plate portion 12 between the opposing plate portions 11, 11, which is curved into a gentle concave arc shape. 13 is its curved portion.

The pad B has a U-shaped body 20 similar to the U-shaped body 10 of the pad A, and a strap 22 is passed to the tips of opposing plate parts 21, 21, and this strap 22 is also curved into a gentle concave arc shape. .

Both U-shaped bodies 10 and 20 are fitted and overlapped, and bolt holes 14 and 23 are formed in opposing plate portions of both U-shaped bodies, and connecting bolts C are passed through the matching holes. Tighten.

The connecting bolt C is a hook bolt in which a hook portion 32 is formed on the front side of a bolt 30 that has a threaded portion 31 only at the rear end.

This embodiment has the above-mentioned configuration. First, the transformer 2 is placed on the pedestal 3, the fixing fitting 7 is inserted between the transformer 2 and the utility pole 1, and the fittings A and B are attached. Set the fitting position according to the spacing between utility pole 1 and transformer 2, connect and fix with connecting bolt C, apply padding A to the utility pole and padding B to the body of the transformer, then connect utility pole 1 and transformer. A thick wire 8 is wound around the container 2, and at the same time, the wire 8 is also hooked onto the hook part 32 of the bolt C. Next, screw in the nut of bolt C further, bring both hook parts 32 close together, and pull both sides of wire 8 to create tension (see Fig. 2), and firmly attach transformer 2 to utility pole 1 via fixing fitting 7, etc. Install.

Incidentally, the fixing metal fitting 7 may be fixed to a telephone pole with a band 9 in advance. In the figure, reference numeral 14 denotes a hole through which the band 9 is passed, which is formed at the rear end of the opposing plate portions 11, 11 of the U-shaped body of the stopper A. 40 indicates a shelf arm.

[Effect of idea]

With this design, the transformer is constructed as described above, so the transformer can be fixed stably and there is no risk of it falling due to shaking such as an earthquake.In addition, the wire that wraps around the utility pole and the transformer can be attached to the hook of the bolt. By hooking it up and screwing in the nut, you can achieve sufficient bondage with just your hands.
