Description

[Detailed Description of the Invention] The present invention relates to a device for attaching a cable head to the arm of a utility pole.

When connecting cables on a utility pole, the conventional method for attaching the cable head to the cross arm is to place the mounting surface of the bracket of the cable head against the side of the cross arm, and then attach the bolts to the bracket and cross arm. is passed through and tightened with a nut.

That is, the cable head must be pressed against the armrest with one hand until the bolt/nut is tightened to a certain extent.

Therefore, bolts and nuts must be tightened with one hand, which is difficult to tighten, and the working posture may become unstable, which is dangerous because the work must be done at heights.

The object of the present invention is to provide a cable head installation device which can eliminate the above-mentioned drawbacks during cable head installation work.

Embodiments of the present invention will be described below with reference to the drawings. 1
1 is a cable head temporary fixing device, which has a U-shaped cross section 11 that engages with the upper surface and both sides of arm A of utility pole P, and a roughly U cross section that hooks and supports mounting bracket B on arm A of cable head H. It is formed integrally with the character-shaped portion 12.

The cable head temporary stopper 1 can be formed by press bending a steel plate or other metal plate.

A bolt through hole 2 that matches the bolt through hole C opened in the bracket B of the cable head H is opened on the opposing surface of the C-shaped section 11 and the approximately U-shaped section 12 of the cable head temporary stop 1. .

The generally U-shaped section 12 has a spacing S at its upper end that is slightly narrowed so that the bracket B can be supported by elastic compression. The notch 3 at the center of the substantially U-shaped section 12 is provided to allow the reinforcing ribs R of the bracket B to escape.

As shown in Fig. 3, for example, when attaching a hoist W to a utility pole P, and removing the cable head H lifted onto the pole from the lifting device F and attaching it to the arm A, the cable of the arm A is Attach temporary fastener 1 to the head installation position (bolt through hole D is open).

That is, as shown in FIG. 2, the U-shaped section 11 of the temporary fastener 1 is fitted onto the armrest A from above. Then, the bracket B of the cable head H is pushed into the substantially U-shaped section 12 against the elasticity of the U-shaped section 12.

When the cable head H is temporarily fixed as described above, the bolts 4 are inserted into the matching bolt holes 2, D, and C, and the nuts 5 are fitted and tightened.

Since the cable head attachment device of the present invention has the above-described structure, the temporary fastener 1 can be easily attached to a predetermined position of the arm arm A by the U-shaped cross section 11, and is engaged with the upper surface and both side surfaces of the arm arm A. There is no wobbling.

The temporary fastener 1 has a cable head H with a cross section of approximately U.
Since it is reliably supported by the shaped part 12, there is no need to press the cable head H against the armrest A when inserting the bolt 4 and tightening the nut 5.

Therefore, the bolts and nuts can be tightened with both hands, making the work easier and effective in improving the safety of work at heights.
