Abstract

PROBLEM TO BE SOLVED: To string a cable stably by arranging a curved metal wheel lower than the wheel not curved, and setting the wheel to have the angle of elevation. SOLUTION: A curved metal wheel 26 is arranged to have the angle of elevation, and the position of the wheel 26 is arranged lower than the wheel pulley 24 not for curved, and when stretching a cable, the cable 21 is pulled downward by the curved wheel 26 being supported from under by the wheel 24. Furthermore, a wheel arm 41 fixes the curved wheel 26 such that it may have a specified angle of elevation, and also when a belt 42 fixes the wheel arm 41 horizontally to a utility pole 13, the curved wheel 26 has the angle of elevation. As a result, the cable stringing work becomes stable, so it becomes possible to string the cable 21 in the direction curved in the horizontal direction, using the curved metal wheel 26.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cable laying method and a curve wheel setting device, and more particularly, to a cable laying method and a curve for stably laying a cable when a curve wheel is used. The present invention relates to a wheel attachment device.

[0002]

2. Description of the Related Art Conventionally, a method of arranging a communication optical cable over a telephone pole or the like has been used. FIG. 6 shows the conventional cable bridging method. FIG. 6A shows the front, and FIG. 6B shows the side. As shown in FIG. 6, when the cable 72 is laid in the direction curved in the horizontal direction, the arm 76 is fixed horizontally to the utility pole 75, and the curved wheel 73 is hung on the arm 76. Further, a swing wheel 74 that is not for a curve is suspended by the suspension wire 71, the traversing direction of the cable 72 is curved in the horizontal direction by the curve swing wheel 73, and the cable 7 is further bent by the swing wheel 74.
2 was negotiated in a linear direction.

[0003]

It is assumed that a curve wheel 73 is used.
If the height of the wheel 72 not used for the curve is the same as that of the wheel 72, when the tension of the cable 72 increases, the cable 7
2 may come off the wheel of the curve wheel 73. For this reason, in order to reliably contact the cable 72 with the wheel of the curved wheel 73, the position of the curved wheel 73 is higher than the position of the non-curved wheel 74. Since the cable 72 is pulled upward, when pulling the cable 72, the cable 72 sometimes raises and moves a non-curve wheel 74 before and after the curve wheel 73 by the cable 72. Further, the direction of the curve wheel 73 is not determined due to irregular increase and decrease of the pulling force, and the cable 7 is attached to the wheel of the curve wheel 73.
2 (or the pulling rope of the cable 72) cannot be completely maintained, so that it is difficult to determine the mounting position of the curving wheel 73, and the towing operation is interrupted during the pulling of the cable 72, and the curving wheel 73 is stopped. It was necessary to correct the mounting position of. SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to provide a cable tying method and a curve wrench mounting device that can eliminate the above-mentioned disadvantages of the conventional example and stably lay a cable using a curve wrench. .

According to a first aspect of the present invention, there is provided a cable laying method for laying a wheel not for a curve and a cable led by the curve wheel. The position of the curved wheel is lower than the position of the non-curved wheel, so that the curved wheel has an elevation angle.

[0005] According to the configuration of the first aspect of the present invention, the curb wheel has an elevation angle, and the position of the curb wheel is set lower than the position of the non-curve wheel. Since the cable is pulled downward by the curved wheel, and the cable is supported from below by the non-curved wheel, the cable laying operation is stabilized.

Further, the structure of the second invention is characterized by comprising a wheel arm for fixing the curved wheel so as to have a predetermined elevation angle, and a belt for fixing the wheel arm horizontally to a telephone pole. It is a curb wheel mounting device.

Further, according to the configuration of the second aspect of the present invention, the gold wheel arm fixes the curved wheel with a predetermined elevation angle, and the belt fixes the wheel arm horizontally to the electric pole. Can be arranged to have an elevation angle. For this reason, it becomes easy to implement the cable bridging method according to the configuration of the first invention.
