2. Description of the Related Art Conventionally, a monorail facility is known as a facility for carrying a load while being self-propelled while being supplied with power. When such a monorail facility is used, most of the facilities supply power to the self-propelled carriage by contact between a power supply rail laid along the transport rail and a current collector of the carriage.

[0003]

However, in such a conventional load transport equipment, it is necessary to lay a power supply rail along the transport rail of the truck so as to keep the distance from the truck constant. The laying work is difficult, and there is a problem that work efficiency is poor. In addition, since power is supplied to the trolley by contacting the power supply rail with the current collector of the trolley, maintenance is indispensable due to its wear, and sparks are generated. There was a risk of fire and endangering workers.

[0004] The present invention is to solve the above problems,
An object of the present invention is to provide a guide line cartridge that can supply power without contact, has good laying workability, requires no maintenance, is efficient, and can ensure the safety of workers.

[0005]

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, an induction line cartridge according to the present invention is provided with a line through which a high-frequency sine wave current flows, and generates an electromotive force in an adjacent coil. A first bracket having a U-shaped cross section is placed with its concave portion facing upward, and a second bracket with a hanger having a concave portion at its tip is disposed at predetermined intervals in the concave portion, and In the concave portion, the line is fitted in the longitudinal direction, a thermosetting resin or a thermosetting resin to which sand is added is injected into the concave portion of the first bracket, and the line is fixed. Is what you do.

[0006]

According to the configuration of the present invention, an electromotive force is generated in an adjacent coil by energization (alternating current) of the induction line, and power is supplied without contact. Further, since the guide line is fixed in the cartridge, the guide line is laid only by placing the cartridge on the floor. In addition, since the power is supplied in a non-contact manner, no spark is generated, and there is no danger of flammable oil or the like being ignited in the vicinity of the spark. Furthermore, there is no need to worry about wear of the power supply rail and the current collector as in the related art, and maintenance-free operation is realized.

The detailed circuit configuration will be described with reference to the circuit diagram of FIG. The power supply device M includes an AC 200 V three-phase AC power supply 41, a converter 42, a sine wave resonant inverter 43, a transistor 44 and a diode 45 for overcurrent protection. The converter 42 includes a diode 46 for full-wave rectification, a coil 47 constituting a filter, a capacitor 48, a resistor 49, and a transistor 50 for short-circuiting the resistor 49. Transistors 51 and 52 driven by rectangular wave signals alternately oscillated
, A current limiting coil 53, a current supplying coil 54 connected to the transistors 51 and 52, and a capacitor 55 forming a parallel resonance circuit with the induction line 14.
Note that the transistor control device is omitted.

The power receiving unit 15 is provided with a capacitor 56 constituting a resonance circuit which resonates with the frequency of the pickup coil 26 and the induction line 20 in parallel with the pickup coil 26, and a switch 57 in parallel with the capacitor 56 of this resonance circuit. A rectifying diode 58 is connected, and a stabilized power supply circuit 59 for controlling the output of the diode 58 to a predetermined DC voltage is connected to the diode 58. Stabilized power supply circuit 59

When the power supply is not required, the switch 57 is turned on.

The power supply device M, the guideway 20, and the traveling vehicle 5
The operation of the above circuit configuration will be described. First, an AC 200 V three-phase AC output from an AC power supply 41 is converted into DC by a converter 42, converted into a high frequency, for example, a 10 kHz sine wave by a sine wave resonant inverter 43, and supplied to the induction line 20.

The magnetic flux generated in the induction line 20 generates an electromotive force in the pickup coil 26 of the traveling vehicle 5 which resonates at the frequency of the induction line 20, and the alternating current generated by the electromotive force is a diode of the power receiving unit 15. It is rectified by 58, is regulated to a predetermined DC voltage by a stabilized power supply circuit 59, is converted to a predetermined AC voltage of a commercial frequency through an inverter 64 controlled by the control unit 14, and is used for the traveling motor 13 and the fork.

Thereby, the engine 4 is carried in and out of the engine test bench 2 and the self-propelled trolley 7.

As described above, since the power can be supplied to the traveling vehicle 5 in a non-contact manner and the power can be supplied to the traveling motor 13 and the fork motor 11, there is no need to worry about the wear of the current-carrying rail and the current collector as in the prior art. Maintenance free can be realized. Furthermore, by using a litz wire covered with an insulator for the induction line 20 and the pickup coil 26, further covering it with the cover 21, and fixing it with epoxy resin, there is no exposure of the conductive part, improving safety. Since no spark is generated, the risk of ignition is eliminated and the safety of the worker can be improved. Also,
By supplying a sine wave to the induction line 20, no harmonic is generated, and the generation of radio noise can be eliminated.

Further, since the guide line cartridge X has the guide line 20 fixed in the bracket 16, the guide line 20 can be laid only by being placed on the floor surface, thereby greatly improving the work efficiency. Can be. Further, the guide line cartridge X is movable, and the laying position of the guide line 20 can be easily changed. Furthermore, by incorporating silica sand into the epoxy resin used for the guide line cartridge X, it is possible to manufacture it at low cost and reduce the cost. Note that, instead of silica sand, porcelain sand with low moisture content may be used. Further, not only the epoxy resin but also a thermosetting resin can be used.

Further, since the center L of the pickup unit P can be adjusted so as to be located at the center of the guide line cartridge X and is fixed, the pickup coil 26 has the lowest magnetic flux density generated in the guide line 20 of the guide line cartridge X. Located at a large position, the largest electromotive force is induced, and power can be efficiently supplied.

Further, by arranging non-conductive brushes 31 on the front and rear portions of the main body 10 of the traveling carriage 5, respectively, even if foreign matter is placed on the guide line cartridge X for any reason, it is discharged. If the foreign matter on the guide line cartridge X is a conductive foreign matter, heat generated by the magnetic flux generated in the dielectric line 20 can be prevented, and the danger such as a burn of the worker trying to eliminate the foreign matter can be prevented.

In this embodiment, two pairs of guide lines 20 are laid on the bracket 16 in the guide line cartridge X. However, when two pairs of guide lines 20 cannot be laid, one pair of guide lines 20 is used. Only the bracket 16 may be laid. Needless to say, power down occurs at this time. In addition, a guide line 20 can be further laid on the bracket 16 to increase power.
