[Detailed description of the device]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention This invention relates to a pole-equipment fixing bracket used when installing pole-equipment such as a transformer on a telephone pole.

[0002]

2. Description of the Related Art Conventionally, as shown in FIGS. 6 and 7, when a pole-mounted device A such as a transformer is installed on a utility pole B, first, a pedestal 1 on which the pole-mounted device A is mounted is mounted on the utility pole B. Installation, after this,
The pole device A is placed on the pedestal 1, and the pole device A and the utility pole B are fastened and fixed by the tightening band 2 so that the pole device A does not drop from the pole device A.

When the pole equipment A and the electric pole B are fixed by the tightening band 2, there is a gap between the side wall of the pole equipment A and the side wall of the electric pole B. Therefore, if the tightening band 2 is tightened as it is. Since the pole device A shifts toward the utility pole B side, the spacer metal fitting 3 that fills the gap between the utility pole B and the pole device A is wound around the utility pole B by the mounting band 4 and attached.

[0004]

[Problems to be solved by the invention] Therefore, conventionally,
When the pole-mounted device A is installed on the utility pole B, the pedestal 1 and the spacer fitting 3 must be separately wound around the utility pole B by using the mounting bands 4 and 5, and the workability is poor. There was a problem.

Therefore, the present invention improves the workability of the work of installing the pole equipment on the utility pole by providing a pole equipment fixing fitting that does not require the spacer fitting to be wound around the utility pole by using a mounting band. Is what you are trying to do.

[0006]

In order to solve the above problems, the present invention provides a support arm of a receiving plate on which a pole device is mounted, a side wall of the pole device mounted on the receiving plate, and a utility pole. Spacer metal fittings that fill the gap formed between the side walls are erected.

[0007]

Therefore, it is not necessary to use the mounting band to mount the spacer fitting on the utility pole separately from the pedestal for the pole equipment.

[0008]

An embodiment of the present invention will be described below.

The pole equipment fixing bracket has a support arm 20 attached to the outer side surface of a mounting band 10 wound around and fixed to a utility pole B, and a support plate 19 for mounting the pole equipment A on the upper surface of the support boom 20. It has a different structure.

The mounting band 10 includes a band body 11 and
The first body mounted on both ends of the band body 11 by pivot shafts 12 and 13 so that the band body 11 can be opened and closed
The open / close band 14 and the second open / close band 15.

On the outer surface of the band body 11, as shown in FIG. 1, is a mounting member 1 for mounting an insulator support arm 16.
7 is provided by welding, and the insulator support arm 16 is attached to this attachment fitting 17 by a bolt 18.

As shown in FIG. 1, mounting fittings 21 for mounting the support arms 20 of the receiving plate 19 are provided on both ends of the band body 11 by welding, and the supporting arms 20 are attached to the mounting fittings 21 by bolts 22. Installed. A receiving plate 19 for mounting pole equipment such as a transformer is attached to the support arm 20 by a bolt 23.

At the end of the supporting arm 20 on the band body 11 side, as shown in FIG. 5, an upward U-shaped fixing plate 3 is provided.
3 is attached by welding. As shown in FIG. 2, a spacer metal fitting 34 for filling a gap formed between the side wall of the pole equipment A and the side wall of the electric pole B placed on the receiving plate 19 is fixed to the fixing plate 33 by the bolt 35. Installed.

The spacer fitting 34 is the spacer body 3
6 and a mounting plate 37, and the spacer body 36 is mounted on the upper end of the mounting plate 37 by welding. Below the mounting plate 37, three through holes 38 for the bolts 35 are provided at upper and lower positions so that the mounting position can be adjusted in the vertical direction. The spacer body 36 has substantially rectangular side walls, and the left and right side walls facing each other have utility poles B.
And is formed in a curved surface so as to follow the curved surface of the columnar device A.

As shown in FIG. 1, the spacer fitting 34 can be attached to the receiving plate 19 so as to be used also as the pin insulator support metal 24. Mounting hole 39 for mounting insulator
Are formed.

The first opening / closing band 14 and the second opening / closing band 15 are respectively attached to the ends of the fittings 21 provided at both ends of the band body 11 on the rotating shafts 12 and 13 fixed in the vertical direction. It is rotatably attached. As a result, the first opening / closing band 14 and the second opening / closing band 15
Is capable of opening and closing with respect to the band body 11.

Tongue pieces 25 projecting toward the band body 11 along the inner surface of the band body 11 are provided at the ends of the first opening band 14 and the second opening band 15 on the rotary shafts 12 and 13, respectively. , 26 are attached by welding.

At the tip ends of the first opening / closing band 14 and the second opening / closing band 15, a fastening metal fitting 27 is attached to connect them. The tightening fitting 27 includes a fixing fitting 29 on the first opening / closing band 14 side fixed to the first opening / closing band 14 by a bolt 28, and a bolt 30 with a nut with a seat rotatably attached to the fixing fitting 29. Consists of.

The tightening fitting 27 on the side of the second opening / closing band 15 is constituted by a bolt 31 and a receiving fitting 32 on the second opening / closing band 15.
2, the seat nut portion of the bolt 30 at the tip of the first opening / closing band 14 is engaged.

When the pole equipment A is installed on the utility pole B using the pole equipment fixing bracket constructed as described above, the spacer fitting 34 is previously attached to the fixing plate 33 at the end of the support arm 20.
Are attached with bolts 35. At this time, the mounting positions of the insertion holes 38 of the mounting plate 37 and the fixed plate 33 are adjusted according to the height of the pole device A to be installed.

Next, as shown by the alternate long and short dash line in FIG. 3, the first opening / closing band 14 and the second opening / closing band 15 are pivoted outward about the pivot shafts 12 and 13 to open them.

Thus, the first opening / closing band 14 and the second opening / closing band 14
When the open / close band 15 is opened by rotating it outwardly, the tongues 25 and 26 at the ends on the rotating shafts 12 and 13 both rotate inward and project inward.

In this state, the opened first opening / closing band 14
When the utility pole 1 is fitted inside the second opening / closing band 15 and the inner surface of the band body 11 is pulled toward the outer surface of the utility pole 1, the tongue pieces 25 and 26 protruding inward are pressed against the outer surface of the utility pole 1. The tongue pieces 25 and 26 are
The first opening / closing band 14 and the second opening / closing band 15 are rotated outwardly around the rotating shafts 12, 13 as a center.
The inward-closing bands 14 and 15 are wound around the telephone pole 1 by rotating inwardly around.

The first opening / closing band 14 is attached to the rotary shaft 1.
When it is rotated inwardly about 2, the bolt 30 with a nut with a seat at the tip also rotates inwardly by the momentum, and the bolt 30
The nut portion with a seat is hooked on the receiving fitting 32 at the tip of the second opening / closing band 32.

Then, the seat nut of the bolt 30 is rotated and tightened, and the band body 11 and the first opening / closing band 1
4 and second opening / closing band 15
Is fixed to the telephone pole 1.

After that, the pole equipment A is placed on the receiving plate 19, and the pole equipment A and the electric pole B are tightened and fixed by the tightening band 40 as shown in FIG.

[0027]

As described above, according to the present invention, when the pedestal equipment pedestal is used to install the pole equipment on the utility pole, the spacer fittings separate from the pole equipment pedestal are used. Since it is not necessary to wind and fix the utility pole around the utility pole, the workability of installing the pole equipment on the utility pole is improved.
