Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a power generator for a driven pulley of a cableway provided on a driven pulley, that is, a trailing pulley, a tension pulley, or the like, in a driven stop of a cableway.

[0002]

2. Description of the Related Art Cableway facilities for suspending and transporting a carrier using suspension means for suspending the carrier on a rope are widely used for tourist transportation, skier transportation, etc. in mountainous areas and snowy areas. . In general, these cableway facilities suspend or tow the carrier by a rope wound endlessly between a driving pulley and a driven pulley disposed at both ends of the carriage, respectively, and pull the rope. With the movement of the article, the carrier is operated to carry out the transportation. This drive mode is roughly classified into the following two modes. One of them is a fixed driving system, in which a driving pulley equipped with a drive device is arranged at the driving side stop at one end, and a tension pulley having a tension device is arranged at the driven side stop at the other end. The rope is endlessly wound between the driving pulley and the tension pulley, and the carriage is operated by driving the rope by the rotation of the driving pulley. The other type is the driving tension system, in which a driving tension pulley with both drive and tension functions is installed at the driving-side stop at one end, and folding guidance is provided at the driven-side stop at the other end. A terminal pulley having only the function of ‘1’ is provided, and the rope is wound endlessly between the driving tension pulley and the terminating pulley, and the rope is driven by the rotation of the driving tension pulley to operate the carrier. Is. And,
Here, the driving pulley or the driving tension pulley, which has a driving function, is collectively referred to as a driving pulley.
Further, a tension pulley or a terminal pulley that does not have a driving function will be collectively referred to as a driven pulley.

In such a cableway facility, a drive-side stop including a drive-side pulley requires a large amount of power for driving power of a drive unit, but a driven-side stop requires a signal,
Generally, a small capacity is sufficient for the required power only for power demand such as security or lighting. Further, in many cases, the driven-side stop is located on a mountain or the like of the cableway and is provided relatively far from the village, and it is often difficult to receive power supply from the outside. Therefore, in ordinary cableway equipment, power is supplied from the outside at the drive-side stop where the required power is large, and the driven-side stop is installed with a dedicated distribution line from the drive-side stop to supply power. Has been done.

[0004]

However, although the power consumption of the driven-side stop is generally small as described above, it is necessary to spend a great deal of money to provide a distribution line, which results in a large construction cost and maintenance. , The maintenance cost is high,
It was not economic.

The present invention has been made in view of the above circumstances in order to improve it, and it is not necessary to provide a distribution line to reach the driven-side stop, which consumes a small amount of electric power, and is required for the driven-side stop. The purpose of the invention is to provide a power generation device for the pulley on the driven side of the cableway, which can obtain electric power and economically construct and operate the cableway equipment.

It is configured such that rotation can be transmitted from the driven pulley to the generator via the transmission means and the speed increasing means, and the required power is supplied to the driven stop by the power generation of the generator. The generator of the driven pulley of the cableway,

In a cableway facility for suspending a carrier on a line stretched in a track and operating the carrier along with the movement of the line, the driven pulley is fitted to a driven pulley shaft and integrally rotates. It is configured such that rotation can be transmitted from the driven pulley shaft to the generator via the transmission means and the speed increasing means, and the required power is supplied to the driven stop by the power generation of the generator.
