DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a telephone pole band.

[0002]

2. Description of the Related Art As a conventional example, a pair of semicircular arc-shaped band pieces which are fastened to each other by a tightening bolt and a tightening nut at one end side of a supporting material for a columnar article such as equipment are hinged to each other. There is a structure in which a hinge is provided at a hinge connecting portion to always bias the band piece in a closing direction (Japanese Utility Model Laid-Open No. 4-58039).

[0003]

SUMMARY OF THE INVENTION
Since a spring is provided at the hinge joint of the band piece so as to always bias the band piece in the closing direction, when the band body having such a structure is mounted on a telephone pole by using a manipulator, for example, the above-mentioned conventional (conventional) (Before the state shown in FIG. 4 in the example publication), the other ends of the pair of band pieces are in contact with each other and are closed. Therefore, the other end of the band pieces in the closed state is pressed against the utility pole, and the pressing force is applied. , A component force in the left-right direction is generated from this, and it is necessary to expand the band piece against the bias of the spring and attach it to the telephone pole by this component force, but the direction of this component force is the pressing force. Because it is close to a right angle to the direction, a considerable pressing force is required.In that case, the band piece buckles before opening itself, so the thickness of the band piece may be increased unnecessarily or the structure may become complicated. Need to take measures such as In fact unsuitable year.

The present invention has been made by focusing on the drawbacks of the conventional example.

SUMMARY OF THE INVENTION A central band piece provided with a support for a column-mounted article such as equipment, and a pair of side parts arranged on both sides of the central band piece and fastened together at one end by a tightening bolt and a tightening nut. A connecting cylinder formed of a band piece and provided at one of the end of the center band piece and the other end of the side piece is engaged between the holding pieces which are vertically arranged on the other side. Then, a connection nut is screwed into one end of a connection bolt protruded from one of the holding pieces through the connection cylinder by the other, and one end of a coil spring wound around the connection bolt is attached to the side band piece. The other end is pressed against the inner surface of the central band piece facing the power pole, and the other end of the side band piece is pressed against the inner surface of the central band piece facing the power pole. It is arranged inside.

1 is a plan view, FIG. 2 is a cross-sectional view, and FIG. 3 is a side view of a power pole band according to the present invention. explain.

A power pole band A according to the present invention comprises a central band piece 2 provided with a support 1 for a poled article such as equipment, and a pair of side band pieces 3 disposed on both sides of the central band piece 3. 3 '
And

The center band piece 2 is provided with a notch 4 provided at the center of both ends along the longitudinal direction of the center band piece 2,
Connecting cylinders 5 and 5 are provided on the upper and lower sides of the notch 4 so as to be folded back into an annular shape.

The side band pieces 3, 3 'are fastened to each other by a tightening bolt 6 and a tightening nut 7 at one end. Projecting outward, the holding piece 8,
The connecting tubes 5, 5 provided at the end of the central band piece 2 between
And connecting bolts 10 are inserted from one of the holding pieces 8, 8 so as to pass through the spiral portions of the coil springs 9, 9 interposed between the connecting cylinders 5, 5 and the connecting cylinders 5, 5. And a connection nut 11 is screwed into the tip of a connection bolt 10 protruding from the other, and the center band piece 2 and the side band pieces 3 and 3 ′ arranged on both sides of the center band piece 2 are turned around each other. It is movably connected.

An inner surface of the coil spring 9 opposing the electric pole D of the locking portion 12 having one end side near the connecting cylinder 5 and a part of the side piece 3, 3 'being formed outwardly. The other end is engaged with the notch 13 provided at the center in the width direction of the other end of the side band pieces 3 and 3 'along the longitudinal direction of the side band piece through the notch 4. ,And,
The central band piece 2 is pressed and locked on the inner surface.

The tightening bolt 6 is formed of a desired eyebolt, and has a ring-shaped head 6a provided at one end of one of the side band pieces 3 at the upper and lower portions of a support frame 14 having a vertical cross-sectional groove shape. 14a, 14b, the upper and lower pieces 14a,
It is pivotally supported by a pivot pin 15 erected on 14b.

The tightening nut 6 is screwed to the tip of the tightening bolt 6, and a tightening receiving member 16 for receiving the tightening nut 7 is provided at one end of the other side band piece 3 '. A notch 17 is formed at the center of the end of the tightening receiving piece 16 so that the threaded rod of the tightening bolt 6 can enter and exit.

The support member 1 provided on the center band piece 2
Is provided at the center of the outer surface of the center band piece 2 by welding, and the supporting material 1 has a structure for supporting the upper part of the pole transformer. Description is omitted.

The supporting member 1 may be, for example, an arm, and may be of any type as long as it supports the pillar-mounted article and is fixed to the central piece 2.

Thus, in order to attach the power pole band A of the present invention to the power pole D, at predetermined positions of the power pole D, the coil springs 9 interposed at the connection portions with the central band piece 2 respectively bias each other. It is greatly expanded outward,
One side of the side band pieces 3, 3 'maintained in the double-open state is directed to the utility pole D, and one part of the supporting member is gripped by a manipulator or a human hand to horizontally move the band body A in the utility pole D direction.
When the utility pole D surface reaches the far end of the band, the utility pole D surface pushes the other end of the side band pieces 3, 3 'protruding inward from the inner surface of the central band piece 2, so that the recoil thereof automatically One end of each of the side band pieces 3 and 3 'is pivotally moved inward about the connection bolt 10 and closed, so that the utility pole D is bound by the center band piece 2 and the pair of side band pieces. One end of each of the side band pieces 3 and 3 'is opposed to and close to each other. Thereafter, the two ends are tightened with a tightening bolt and a nut, whereby the electric pole band A is attached to the electric pole D.

[0016]

As described above, since one end of a pair of side band pieces is maintained in a double-open state around the center band piece, the manipulator is used because it is easy to fit into a telephone pole. At the same time, when the coil spring is fitted into the connection between the respective band pieces at the factory and assembled, if the assembly is performed in the double-open state, the assembly is performed against the repulsive force of the coil spring. Since there is no need to attach it, it can be easily and inexpensively assembled without using special assembly equipment,
Suitable for mass production.
