DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a power supply line erection structure for a power supply line in a non-contact power supply device for reducing the number of installation steps and obtaining reliability after laying.

[0002]

2. Description of the Related Art Conventionally, a non-contact power supply device travels a carrier along a traveling rail. A power supply line to which a high-frequency current is supplied is provided on the traveling rail, and a non-contact power supply line is provided on the carrier side. An opposing secondary coil is provided, and driving power is obtained on the carrier on the secondary coil side by electromagnetic induction between the power supply line and the secondary coil. Japanese Patent Application Laid-Open No. 11-2
As described in JP 91796, a cable is used in which a plurality of copper fuel wires are arranged, and these are integrally covered with a covering member. FIG. 5 shows a part of the appearance of the power supply line of the prior art example. The power supply line 5 is connected to the traveling rail 51.
The hanger 52 is provided everywhere to support 3. The power supply line 53 is supported by a hanger upper part 54.

However, in the above-mentioned prior art, since the cable is delivered in the form of a drum from an electric wire maker, the cable is bent and twisted, so that the cable must work while straightening when the traveling rail is installed. . The power supply lines other than the hanger support parts provided everywhere on the running rail are difficult to go completely straight. Therefore, it is necessary to reduce the interval between the support hangers, so that it is necessary to increase the number of hangers. In addition, when laying a power supply line on a traveling rail attached to a hoistway wall found in elevators etc., rectification of the power supply line and erection work require high work, so enormous work including safety is required. There was a problem.

SUMMARY OF THE INVENTION The present invention has been made in view of the above circumstances, and has as its object to reduce the number of man-hours for erection of a power supply line in a non-contact power supply device, and to enhance the erection work safety and reliability after laying.

[0005]

In order to achieve the above-mentioned object, the present invention provides a method of forming a single rod material using a molded copper for a power supply line in a non-contact power supply, and forming one rod member of a support portion. It is shaped so that it can be inserted and erected in the part.
