BACKGROUND OF THE INVENTION
BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cable bridging method and a curved gold wheel mounting apparatus, and more particularly to a cable bridging method and a curved gold wheel mounting apparatus that can stably carry a cable when a curved gold wheel is used. is there.
[0002]
[Prior art]
Conventionally, a method of negotiating a communication optical cable with a utility pole has been used. FIG. 6 shows the conventional cable routing method. FIG. 6A shows the front, and FIG. 6B shows the side. As shown in FIG. 6, when the cable 72 is routed in the direction curved in the horizontal direction, the arm 76 is fixed horizontally to the utility pole 75, and the curved metal wheel 73 is suspended from the arm 76. Further, the gold wheel 74 not for curve is suspended by the suspension wire 71, the direction of the cable 72 is curved in the horizontal direction by the curve gold wheel 73, and the cable 72 is hung in the straight direction by the gold wheel 74. It was.
[0003]
[Problems to be solved by the invention]
If the position of the curve gold wheel 73 and the position of the non-curve money wheel 74 are the same height, the cable 72 may come off the wheel of the curve wheel 73 when the tension of the cable 72 increases. Therefore, in order to ensure that the cable 72 is brought into contact with the wheel of the curve gold wheel 73, the position of the curve gold wheel 73 is arranged higher than the position of the gold wheel 74 that is not for curve use. Therefore, when the cable 72 is pulled, the non-curve gold wheel 74 before and after the curve gold wheel 73 may be lifted and moved by the cable 72.
In addition, the direction of the curve gold wheel 73 is not determined due to irregular increase and decrease in traction tension, and the state where the cable 72 (or the tow rope of the cable 72) is in contact with the wheel of the curve gold wheel 73 cannot be completely maintained. It was difficult to determine the mounting position of the car 73, and it was necessary to correct the mounting position of the curve metal wheel 73 by interrupting the towing work while the cable 72 was being pulled.
Accordingly, an object of the present invention is to provide a cable bridging method and a curved gold wheel mounting device that can eliminate the drawbacks of the above-described conventional example and can stably carry a cable using a curved gold wheel. .
[0004]
[Means for Solving the Problems]
In order to solve the above-mentioned problem, the configuration of the first invention of the present application is a cable bridging method for negotiating a non-curve metal wheel and a cable guided by the curve metal wheel. It is arranged to be lower than the position of the not-shown gold wheel so that the curved gold wheel has an elevation angle.
[0005]
According to the configuration of the first aspect of the invention, the curve gold wheel has an elevation angle, and the position of the curve gold wheel is set lower than the position of the gold wheel that is not used for the curve. The cable is pulled downward by the car, and further, since the cable is supported from below by the gold car that is not for the curve, the cable interfering work is stabilized.
[0006]
Furthermore, the configuration of the second invention includes a belt, a gold wheel arm, and a gold wheel fixing bracket, the belt horizontally fixes the gold wheel arm to a power pole, and the gold wheel fixing bracket is a curved metal. A curved metal wheel mounting device characterized in that a car is fixed to a metal wheel arm fixed horizontally to the power pole, and at that time, the metal wheel fixing bracket adjusts the elevation angle of the curve metal wheel to a predetermined value. .
[0007]
Furthermore, according to the configuration of the second invention, the belt fixes the gold wheel arm horizontally to the utility pole,
The gold wheel fixing bracket fixes the curve metal wheel to the metal wheel arm fixed horizontally to the utility pole. At this time, the gold wheel fixing metal metal makes the elevation angle of the curve metal wheel a predetermined value. The car 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.
