Description

TECHNICAL FIELD The present invention relates to a device for supplying electric power to a carriage at a stop of a cableway facility.

Cableway equipment is a transport facility that suspends carriers on ropes suspended in the air to transport personnel and goods, and is often used as a means of transportation for personnel on mountain slopes and for skiers and snowboarders at ski resorts. It is In addition, since cableway facilities do not require rails to be laid on the ground like railroads, and require less land for tracks, they have come to be used as a means of public transportation in urban areas, especially overseas. there is

In this way, when operating cableway facilities that operate closed-type carriages such as gondola lifts and ropeways in urban areas as a means of daily transportation, each carriage must be air-conditioned to improve the comfort of passengers. It is desirable to have a device, a lighting device in the passenger car, or the like. However, as is well known in the past, it is difficult to supply power to the carriages that move along the tracks in cableway facilities. Therefore, it was difficult to equip the carrier with equipment that consumes a large amount of power, such as an air conditioner.

In this way, charging after the operation ends requires a large number of chargers for a gondola lift that operates a large number of carriers, which increases the cost. Conventionally, it has been proposed to charge a storage battery (see Patent Document 1, for example). The technology described in Patent Document 1 includes a charging connector attached to the outer surface of the carrier and connected to a storage battery, and a charging connector provided in a stop arranged in the middle of the cableway, while the carrier moves within the stop. and a power supply device connected to the electric supply, so that the storage battery can be charged even when the carriage is moving within the station.

In the conventional technology as described above, it is desirable that dust, dirt, and the like should not adhere as much as possible between the charging connector and the electricity supply element in order to prevent troubles such as sparks. SUMMARY OF THE INVENTION It is an object of the present invention to provide a power supply device for a cableway facility that can keep the contact surface between the power supply side and the storage battery side in good condition. do.

The invention of claim 1 is a cableway facility comprising a running rail on which a gripping machine of a carrier runs at a stop and a U-shaped guide rail for guiding an end roller provided at the end of the gripping machine. a power supply rail extending from a side surface of the guide rail on the side of the gripping machine; an arm extending from a shaft supporting the end roller of the gripping machine toward the power supply rail; and a current collector, wherein the current collector and the power supply rail come into contact with each other to supply power to the carriage.

According to a second aspect of the present invention, there is provided the power supply device for a cableway facility according to the first aspect, wherein the power supply rail has a groove in which a power supply rail is extended, and the current collector is fitted with the groove. It is characterized by having a brush for

According to the present invention, since the power supply rail is provided on the inner side surface of the U-shaped guide rail, it is difficult for dust and dirt to adhere to the power supply rail, and good contact between the brush and the power supply rail can be maintained. can. Further, by forming a groove in the power supply rail and fitting the brush into the groove, the contact between the brush and the power supply rail is ensured.

Hereinafter, specific embodiments of the present invention will be described with reference to the drawings. In this embodiment, an automatic circulation type cableway will be described as a representative example of the cableway facility. FIG. 1 is a schematic diagram of an automatic circulation cableway. The automatic circulation cableway 10 has a stop 11 and a stop 12 at the end of the track, and each of the stops 11 and 12 is provided with a driving pulley 13 and a driven pulley 14 rotatably. A cable 15 is wound endlessly around the driving pulley 13 and the driven pulley 14, and by rotating the driving pulley 13, the cable 15 circulates and moves between the stops 11 and 12. . A plurality of carriages 18 are suspended from the cable 15 at predetermined intervals in the track.

The carriage 18 is detachable from the cable 15, is attached to the cable 15 and moves with the cable 15 on the track, and is separated from the cable 15 within the stations 11 and 12. - 特許庁A U-shaped running rail 16 and a running rail 17 are laid at the stops 11 and 12, respectively. move to First, the carrier 18 arriving at the stops 11 and 12 is separated from the rope 15, transferred to the running rails 16 and 17, and decelerated by the transfer device provided along the running rails 16 and 17. When the carrier 18 decelerates to a speed at which passengers can get on and off, it turns back to the departure side in the stops 11 and 12 while maintaining that speed, and passengers get on and off during this time. After being accelerated to the same speed as the speed of the cable 15, the carrier 18 that has turned back to the departure side is attached to the cable 15 and detached from the running rails 16 and 17 and departs into the track.

FIG. 2 is a diagram showing part of the stops 11 and 12. As shown in FIG. The gripping machine 20 of the transporter 18 is equipped with running rollers 21 rolling on the running rails 16 and 17 and end rollers 22 at the ends opposite to the running rollers 21 . At the position of the end roller 22, a U-shaped guide rail 19 extends in parallel with the outer periphery of the running rails 16, 17, so that the posture of the carrier 18 traveling at the stops 11, 12 is kept constant. be kept. An energized power supply rail 23 extends along the inner side surface of the guide rail 19 , while the gripper 20 is provided with a current collector 24 that contacts the power supply rail 23 . A wire cable 25 is connected to the current collector 24 , and the other end of the wire cable 25 is connected to a storage battery 26 in the carrier 18 . In the stations 11 and 12, the power supply rail 23 and the current collector 24 are brought into contact with each other to move the carriage 18. During this time, electric power is supplied to the carriage 18 side and the storage battery 26 is charged.

FIG. 3 is a front view of the gripping machine, and FIG. 4 is a plan view of the gripping machine. The current collector 24 has a bracket 27 , an arm 28 and a brush 29 . One end of the bracket 27 is fixed near the attachment portion of the end roller 22 of the gripper 20, and obliquely protrudes toward the guide rail 19 in a plan view. An arm 28 is rotatably supported in the horizontal direction at the end of the bracket 27 on the side of the guide rail 19 . A plurality of conductive brushes 29 are attached to the tip of the arm 28 so as to extend in the moving direction of the carrier 18 . Ends of a spring 30 are connected to the intermediate portion of the arm 28 and the tip of the bracket 27, respectively. there is

On the other hand, a power supply rail 23 is provided on the side of the guide rail 19 on the gripper 20 side. Grooves 32 are formed along the moving direction of the gripper 20 at positions corresponding to the brushes 29 of the current collector 24 on the side of the power supply rail 23 on the gripper 20 side. A power rail 31 of conductor extends. Electricity is supplied to each power supply rail 31 , and the brushes 29 are fitted in the grooves 32 , and the brushes 29 and the power supply rails 31 abut to supply power to the carrier 18 side.

According to the above configuration, since the power supply rail 23 is provided on the inner side surface of the U-shaped guide rail 19, the power supply surface of the power supply rail 23 becomes a vertical surface, making it difficult for dust and dirt to adhere to the power supply surface. Thus, a good contact state between the brush 29 and the power supply rail 31 can be maintained. Further, by forming the groove 32 in the power supply rail 23 and extending the power supply rail 31 inside the groove 32, it becomes more difficult for dust and dirt to adhere to the power supply rail 31, and the brush 29 is fitted in the groove 32. As a result, the contact position between the brush 29 and the power supply rail 31 is maintained at a specific position to ensure contact. Moreover, according to this configuration, since a bracket or the like for attaching the power supply rail 23 is not required, it can be easily applied to existing facilities.
