DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a pole mounting device such as a utility pole device.

[0002]

2. Description of the Related Art As disclosed in Japanese Utility Model Publication No. 1-21933, for example, a vertical mounting cylinder provided on one side of a utility pole device is attached to a support cylinder which is previously provided on a peripheral surface of a utility pole by a band body. While inserting and engaging from above and connecting, a through hole is provided on the peripheral surface of both the support cylinder and the mounting cylinder, which is located on a straight line in the horizontal direction, and a bolt rod penetrates through the through hole from one side of the support cylinder,
There is one in which a nut is screwed into a tip of a bolt rod protruding to the other side and tightened.

[0003]

The support cylinder used in the above-mentioned conventional example is formed of a pair of left and right holding portions with a cut in the front end. This is because when the mounting cylinder inserted and engaged with the support cylinder is integrally tightened with a bolt rod and a nut, the inner surface of the holding portion is brought into close contact with the outer surface of the mounting cylinder to securely hold the mounting cylinder. In order not to play in the direction, it is essential that the holding piece has elasticity. This in turn leads to impaired rigidity of the support cylinder, resulting in a reduction in the strength of the device itself. In addition, the through holes provided in the mounting cylinder and the support cylinder and the outer diameter of the bolt rod do not fit together. There is a dimensional difference for fitting, especially in the case of a support cylinder, since the pair of holding pieces are displaced at a slight angle with respect to the axis of the bolt rod at the time of the above-mentioned tightening, the holding piece is provided on the holding piece. It is necessary to increase the horizontal diameter of the through hole by an amount corresponding to the amount of movement. Therefore, when wind pressure acts on the attached device, a horizontal torsion force acts on the mounting cylinder, but when the wind pressure is strong, the mounting cylinder and the outer peripheral surface of the mounting cylinder are in close contact with respect to this twisting force. The mounting cylinder rotates left and right each time by the dimensional difference described above, because the frictional force due to the wide surface contact with the holding piece cannot withstand it.

The amount of rotational movement due to the above dimensional difference is 3 to 5 m.
m, and the bolt rod is of a penetrating type, so that further rotation can be completely prevented. However, in the case of the above-mentioned known example, for example, the separation distance of the mounted pole equipment from the utility pole is small. The more the displacement, the larger the amount of displacement in the device part, and there is a possibility that its use cannot be sufficiently achieved.

The present invention pays attention to such a drawback of the conventional example, and securely holds the mounting cylinder while maintaining the rigidity of the support cylinder.
The present invention was created with the aim of providing a pole mounting device such as a utility pole device having a structure that does not cause slight movement against external force from any direction.

[0006]

A vertical mounting cylinder fixedly mounted on one side of a column to be mounted on a device or the like is inserted into and engaged with a support cylinder projecting from a peripheral surface of a utility pole from above. Let me
The distal end of a fixing screw screwed into a screw hole provided on the peripheral surface of the support cylinder is pressed against the inner surface of the mounting cylinder.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 shows an embodiment of a pole mounting device such as a utility pole device according to the present invention. FIG. 1 is a plan view showing a pole arm, and FIG. FIG. 3 is a partially cut-away side view, FIG. 4 is a front view, and FIG. 5 is a plan view showing a second embodiment of the present invention, showing a power pole arm.

In the drawing, reference numeral 1 denotes a power pole arm, and the arm 1 comprises a main rod 2 composed of a rectangular cylinder arranged in a horizontal direction and a vertical mounting cylinder 3 provided at the base of the main rod 2. A rod is penetrated and fixed at the base of the mounting cylinder 3 and a pair of projections 4 and 4 are provided on opposite sides.

FIG. 5 shows a support cylinder. The support cylinder 5 has a flat U-shaped main body piece 8 having both ends welded and fixed to a band piece 7 of a band body 6 wound around a telephone pole D and assembled. A pair of sub-pieces 9, which are arranged inside the piece 8 and are welded and fixed to the main piece 8, are provided at their upper edges with engaging edges 10, 10 for receiving the protruding members 4, 4.
On the other hand, the holding piece 17 is welded to one side of the support cylinder 5 in a direction perpendicular to the imaginary line connecting the engagement edges 10, 10, and the nut material 11 is inserted into the holding piece 17 and assembled. It is.

[0010] Thus, the band 6 is assembled to the utility pole D, and the supporting cylinder 5 provided on the band piece 7 of the band 6 is protruded from the peripheral surface of the utility pole. Insert the mounting cylinder 3 of the pole arm 1 from above and engage the projections 4, 4 with the engaging edge 1.
The nut member 11 is attached to the holding piece 17 provided on the support cylinder 5, and a fixing screw 13 is screwed into a screw hole formed by the nut material 11. The apparatus according to the present embodiment is configured by being pressed against the inner surface 3 'of the mounting cylinder 3 through the through hole 14 provided in the supporting cylinder 5.

In the second embodiment, the mounting cylinder 3 is formed of a rectangular cylinder, and the supporting cylinder 5 is adapted to this.

[0012]

As described above, according to the present invention, the fixing screw is made to penetrate one side of each of the combined support cylinder and the mounting cylinder while the axes of the supporting cylinder and the mounting cylinder are substantially the same, and the inner end of the mounting cylinder is formed at the tip. The one side of the mounting cylinder is securely clamped by the tip of the fixing screw and the one side of the inner surface of the supporting cylinder, so that it securely exerts the holding force against the load in the front-rear and left-right directions. At this time, the positional relationship between the screw hole of the support cylinder and the through hole of the mounting cylinder is made constant, so that almost no dimensional difference is required between the through hole and the outer diameter of the fixing screw. The amount of rotational movement can be completely eliminated,
A strong and stable mounting state can be obtained.
