Description

[Detailed Description of the Invention] Industrial Application Field The present invention relates to a utility pole band used for attaching equipment such as arms and transformers to utility poles.

Conventional technology As conventional utility pole bands for equipment poles, for example, the structure described in Publication of Utility Model Publication No. 46-20201 and the one described in Japanese Utility Model Publication No.
There is a structure described in Publication No. 60-14307.

The former is a projection in which both tail ends of a pair of band substrates are overlapped on both ends of a band plate, and any locking hole is provided at both ends of the band plate from among the locking holes arranged in the longitudinal direction of the band tail ends. In addition to locking and connecting to each piece, a fastener is provided on both protruding pieces provided facing each other on the proximal end side, and the locking hole is connected to the pole diameter without separating the band board from the band plate. It can be selected as appropriate and locked and connected.

In the latter case, the tail ends of a pair of band pieces are hingedly connected to each other or through a sub-member between them, and receiving members are provided facing each other on the base end side, and bolts and nuts are attached to these. The band body is constructed by assembling and tightening the band pieces.
It is divided into members, each having a plurality of adjustment holes at the same pitch in the longitudinal direction, and these are assembled with each other to match the diameter of the utility pole using connecting bolts and nuts.

Problems to be Solved by the Invention In the case of the technique described in Utility Model Publication No. 46-20201, as mentioned above, when adjusting the column diameter, it is convenient because the band piece and the band-shaped piece can be adjusted by sliding without separating them. When assembling the band body to the utility pole,
Once the bolts and nuts provided on both protruding pieces are removed, the space between the protruding pieces is forcefully expanded to a diameter equal to or larger than the utility pole to engage the utility pole, and then the bolts are inserted between the protruding pieces. Then, the nut is screwed onto the tip of the bolt and tightened, but not only does it require considerable skill and physical strength to perform these tasks on the pole, but the worker also has to wear a thick bolt to prevent electric shock. Because the work is done while wearing rubber or leather gloves, the work of attaching and removing bolts and nuts is time-consuming, and mistakes such as dropping or losing small nuts are common, which is a major cause of work delays.

In the case of the technology described in Japanese Utility Model Application Publication No. 60-14307, since a pair of band pieces are connected by a hinge, the band body can be easily opened left and right around this hinge connection point, and the utility pole can be easily moved from between the receiving members. This means that one of the disadvantages of the former has been solved, but the other disadvantage of having to remove the bolts and nuts of the tightening part has not been solved.

In recent years, the capacity of power distribution lines in urban areas has increased, and along with this, the equipment mounted on poles has also become larger.As a result, the metal fittings that support equipment on utility poles have also been made thicker and thicker to accommodate these demands. Safety is maintained by using a thicker and wider iron material, but it is heavier than before, and it also has less flexibility to the pole surface, and it is difficult to tighten and connect the parts. As the number of bolts and nuts used to connect the poles increased, workability continued to worsen, so improvements in the workability of mounting the poles were long-awaited.

Purpose of the invention The present invention aims to eliminate the drawbacks of the prior art described above and provide a device for attaching equipment to a utility pole that can be easily attached to a utility pole without removing any bolts or nuts on the pole. It is something.

Means for Solving the Problem An equipment support fitting is interposed via a hinge device between a pair of band pieces connected by releasably locking a locking member to a receiving member, and at least one of the hinge devices One is composed of a vertically rotatable tightening nut and a tightening bolt screwed into the tightening nut, and is arranged between the band piece and the equipment support fitting or between the band pieces.

Embodiment The drawings show an embodiment of the utility pole band for equipment poles according to the present invention, in which 1 shows a first band piece, 2 shows a second band piece, and 3 shows a protrusion at the tail end of the first band 1. The locking rod 3 is provided with a collar piece 4 at its tip.

5 is a receiving hole provided at the tail end of the second band piece 2;
The receiving hole 5 consists of a large diameter part 5a and a small diameter part 5b,
Each of the first and second band pieces 1 and 2 is attached to the locking rod 3.
are engaged with the receiving hole 5 and connected to each other so as to be freely detachable.

6 is a first hinge device, and the first hinge device 6 is
A tightening bolt in which a tightening nut 8 is vertically rotatably engaged with an annular piece 7 provided on one of the mutually connected members, and a tip is screwed into the tightening nut 8 through a gap 9 between the annular pieces 7. 10 heads 10' are engaged with a tightening receiving piece 11 provided on the other member that connects them to each other.

12 is a second hinge device;
horizontal pieces 15, 15' are provided above and below the base end piece 14 of the equipment support fitting 13, and the horizontal pieces 15, 1
5', the annular connecting piece 16 provided on the band piece is engaged, and the support shaft 17 is passed through these from the upper horizontal piece 15 side, and the support shaft 1 protrudes from the lower horizontal piece 15'.
A nut 18 is screwed onto the tip of the nut 7.

19 shows the third band piece.

[First example]

The first embodiment is shown in FIG. A piece 7 is provided, and each of the first and second band pieces 1 and 2
and the device support fitting 13 are connected to each other via the first hinge device 6, and the device support fitting 1
3, the first band piece 1 and the second band piece 2 are hingedly connected by the first hinge device 6, and the tail end sides of the first and second band pieces 1 and 2 are opened left and right to open the utility pole D. After the flange piece 4 of the locking rod 3 protruding from the first band piece 1 is inserted into the large diameter part 5a of the appropriate receiving hole 5 provided in the second band 2, both band pieces 1 are inserted. , 2 in the direction of separation from each other, the locking rod 3 is locked in the small diameter portion 5b of the receiving hole 5 to connect both band pieces 1 and 2, and by tightening the tightening bolt 10, the band A is attached to the utility pole. D, and the transformer H etc. are fixedly attached to the support fitting 13.

Note that 20 indicates a reinforcing piece.

[Second example]

In the second embodiment shown in FIG. 2, the first and second band pieces 1 and 2 are made wider and one pair of locking rods 3 and one pair of tightening bolts 10 are used, and the rest is the same as the first embodiment. It is.

[Third Example]

A third embodiment is shown in FIGS. 3 and 4.

In this third embodiment, a third band piece 19 is used together with the first band piece 1 and the second band piece 2.
3, the third band piece 19 and the second band piece 2 are connected by the first hinge device 6, and the third band piece 19 and the equipment support fitting 13 are connected by the second hinge device 12, respectively. The first band piece 1 and the device support fitting 13 are connected by a second hinge device 12.
They are hinged together.
