Description

本発明は、索道設備の停留場において、搬器に電力を供給する装置に関するものである。   The present invention relates to an apparatus for supplying electric power to a transporter at a stop of a cableway facility.

索道設備は、空中に張架した索条に搬器を懸垂し、人員や物資を運ぶ輸送設備であり、多くは山岳傾斜地における人員の移動手段や、スキー場におけるスキーヤーやスノーボーダーの移動手段として利用されている。また、索道設備は、鉄道等のように地上にレール等を敷設する必要がなく線路に要する用地が少なくてすむために、特に海外においては都市部の公共交通機関として運用されるようになってきている。   Cableway equipment is a transportation facility that hangs a carrier on a cable stretched in the air and carries personnel and supplies. Has been. In addition, cableway equipment has been used as a public transportation system in urban areas, especially overseas, because there is no need to lay rails or the like on the ground as in the case of railroads and the like, and less land is required for the track. Yes.

このように、都市部等においてゴンドラリフトやロープウェイのように閉鎖型搬器を運用する索道設備を、日常的な交通機関として運用するにあたっては、乗客の快適性を向上するために各搬器には空調装置や客車内の照明装置等を備えることが望ましい。しかしながら従来周知のように、索道設備においては線路中を移動する搬器へ電力を供給することが困難なことから、一般的には小型の蓄電池を搬器に備え、これを運行終了後に停留場において充電して使用しており、空調装置等の消費電力が大きな機器を搬器に備えることは困難であった。   In this way, when operating cableway facilities that operate closed-type carriers such as gondola lifts and ropeways in urban areas, etc., as daily transportation, each carrier is air-conditioned to improve passenger comfort. It is desirable to provide a device and a lighting device in a passenger car. However, as is well known in the past, it is difficult to supply power to a transporter moving along the track in a cableway facility. Therefore, in general, a small storage battery is provided in the transporter and charged at a stop after the operation is completed. It is difficult to equip a portable device with a device that consumes a large amount of power, such as an air conditioner.

このように運行終了後に充電を行うには、多数の搬器を運用するゴンドラリフト等においては多数の充電器が必要となり費用が嵩むことから、索道設備の運行中に停留場内で搬器が移動しながら蓄電池の充電を行うことが従来提案されている（例えば、特許文献１参照）。特許文献１に記載された技術は、搬器外面に取付けられ蓄電池に接続された充電用コネクタと、索道の途中に配置された停留所内に設けられ、搬器が停留所内を移動する間に充電用コネクタと接触する電気供給子と、電気供給子に接続された電源供給装置とを備え、搬器が停留場内を移動していても蓄電池の充電を行えるようにしている。   In order to charge after the operation is completed in this way, a lot of chargers are required for a gondola lift that operates a large number of carriers, which increases the cost. It has been conventionally proposed to charge a storage battery (see, for example, Patent Document 1). 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 located in the middle of the cableway, while the transporter moves in the stop. And a power supply device connected to the electric supply element so that the storage battery can be charged even when the transporter is moving in the stop.

近時は、電気自動車等の普及などから蓄電池の小型化、大容量化が進んでおり、また、これら蓄電池の急速充電等も行われるようになってきている。このような技術を採用して、上記特許文献１のように停留場内を移動する搬器内の蓄電池を急速充電するようにすれば、搬器が線路中にあっても搬器に搭載した機器類に十分な電力が蓄電池から供給でき、搬器内の環境を快適に保つことができる。   Recently, storage batteries are becoming smaller and larger in capacity due to the spread of electric vehicles and the like, and rapid charging of these storage batteries is also being performed. If such a technique is adopted and the storage battery in the transporter moving in the stop as in Patent Document 1 is rapidly charged, it is sufficient for the equipment mounted on the transporter even if the transporter is on the track. Power can be supplied from the storage battery, and the environment in the container can be kept comfortable.

しかしながら、蓄電池の急速充電においては電力供給側から蓄電池側へ大きな電流を流すため、上記のように搬器が移動しながら充電を行う場合には、供給側の接触子と蓄電池側の接触子とが接触する瞬間および離脱する瞬間に接触子間にスパークが発生して機器を損傷してしまう虞がある。本発明は、このような事情に鑑みてなされたものであって、接触子どうしが接触および離脱するときに起こるスパークの発生を防止することができる索道における電力供給装置を提供することを目的とする。   However, since a large current flows from the power supply side to the storage battery side in the quick charge of the storage battery, when charging is performed while the transporter is moving as described above, the contact on the supply side and the contact on the storage battery side There is a possibility that a spark may be generated between the contacts at the moment of contact and at the moment of separation to damage the device. This invention is made in view of such a situation, Comprising: It aims at providing the electric power supply apparatus in a cableway which can prevent generation | occurrence | production of the spark which arises when a contactor contacts and separates. To do.

請求項１の発明は、索道の停留場内において搬器の移動経路に沿って延設され、通電および通電遮断が可能な給電レールと、前記搬器に備えて前記給電レールと接触する集電子と、前記給電レールの端部位置に備えて前記搬器を検知する搬器検出器と、を備え、前記給電レールと前記集電子とが接触した後に、前記搬器検出器からの信号により前記給電レールへ通電され、前記給電レールと前記集電子とが離脱する前に、前記搬器検出器からの信号により前記給電レールへの通電が遮断されることを特徴としている。   The invention according to claim 1 is a power supply rail that extends along a moving path of the carrier in the cableway stop, can be energized and deenergized, a current collector that contacts the power rail in the carrier, and A carrier detector for detecting the carrier at the end position of the power supply rail, and after the power supply rail and the current collector are in contact with each other, the power supply rail is energized by a signal from the device detector, Before the power supply rail and the current collector are separated from each other, the power supply to the power supply rail is interrupted by a signal from the portable detector.

また、請求項２の発明は、請求項１に記載の索道における電力供給装置において、前記搬器内に蓄電池を備え、前記給電レールから前記集電子を介して前記蓄電池に通電し、前記蓄電池を急速充電することを特徴としている。   According to a second aspect of the present invention, in the power supply device for a cableway according to the first aspect, a storage battery is provided in the transporter, and the storage battery is energized from the power supply rail via the current collector, and the storage battery is rapidly turned on. It is characterized by charging.

本発明によれば、給電レールと集電子とが接触する瞬間および離脱する瞬間には給電レールに通電されておらず、給電レールと集電子とが接触した状態で通電および通電遮断が行われるので、急速充電のように大電流を通電する場合であっても給電レールと集電子間で発生するスパークを防止することができる。   According to the present invention, the power supply rail is not energized at the moment when the power supply rail and the current collector are in contact with each other and the moment when the power collector is separated from the power supply rail. Even when a large current is applied as in the case of rapid charging, it is possible to prevent a spark generated between the power supply rail and the current collector.

単線自動循環式索道の模式図Schematic diagram of single-line automatic circulation cableway 停留場の一部を示した図Figure showing a part of the stop

以下、本発明の具体的な実施の形態を図面を参照して説明する。本実施の形態においては、索道設備の代表例として単線自動循環式索道により説明を行う。図１は、単線自動循環式索道の模式図である。単線自動循環式索道１０は、線路の端部に停留場１１及び停留場１２を有しており、各停留場１１、１２には、原動滑車１３及び従動滑車１４を回転自在に備えている。原動滑車１３と従動滑車１４には、索条１５が無端状に巻き掛けられており、原動滑車１３を回転駆動することにより、索条１５は両停留場１１、１２間を循環して移動する。索条１５には、線路中で所定の間隔となるように複数の搬器１８が懸垂される。   Hereinafter, specific embodiments of the present invention will be described with reference to the drawings. In this embodiment, a single-line automatic circulation type cableway will be described as a representative example of cableway equipment. FIG. 1 is a schematic diagram of a single-line automatic circulation cableway. The single track automatic circulation cableway 10 has a stop 11 and a stop 12 at the end of the track, and each stop 11, 12 is rotatably provided with a driving pulley 13 and a driven pulley 14. A strip 15 is wound around the driving pulley 13 and the driven pulley 14 in an endless manner, and when the driving pulley 13 is driven to rotate, the strip 15 circulates between the two stops 11 and 12. . A plurality of carriers 18 are suspended from the rope 15 so as to have a predetermined interval in the track.

搬器１８は索条１５に着脱自在であって、線路中では索条１５に取り付けられて索条１５とともに移動し、停留場１１、１２内では索条１５から切り離される。停留場１１、１２には、平面視Ｕ字状の走行レール１６及び走行レール１７がそれぞれ敷設されており、索条１５から切り離された搬器１８は、走行レール１６、１７に沿って次のように移動する。まず、停留場１１、１２に到着した搬器１８は、索条１５から切り離されるとともに、走行レール１６、１７に乗り移り、走行レール１６、１７に沿って設けられた移送装置により減速させられる。乗客が乗降可能な速度まで搬器１８が減速すると、その速度を保って停留場１１、１２内を出発側へ折返し、この間に乗客の乗降が行われる。出発側へ折り返した搬器１８は、索条１５の速度と同一速度にまで加速させられた後、索条１５に取り付けられるとともに走行レール１６、１７から離脱して線路中へ出発する。   The carrier 18 is detachably attached to the rope 15, is attached to the rope 15 in the track, and moves together with the rope 15, and is separated from the rope 15 in the stops 11 and 12. In the stops 11 and 12, a U-shaped traveling rail 16 and a traveling rail 17 are laid in a plan view, and the carriage 18 separated from the rope 15 is as follows along the traveling rails 16 and 17. Move to. First, the transporter 18 that has arrived at the stops 11 and 12 is disconnected from the rope 15, is transferred to the traveling rails 16 and 17, and is decelerated by a transfer device provided along the traveling rails 16 and 17. When the transporter 18 decelerates to a speed at which passengers can get on and off, the speed is maintained and the inside of the stops 11 and 12 is turned back to the departure side, during which passengers get on and off. The carrier 18 that is turned back to the departure side is accelerated to the same speed as that of the rope 15, is attached to the rope 15, is detached from the traveling rails 16 and 17, and starts into the track.

図２は、停留場１１、１２の一部を示した図である。搬器１８の握索機２０には、走行レール１６、１７上を転動する走行ローラー２１を備えるとともに、走行ローラー２１とは反対側の端部にエンドローラー２２を備えている。エンドローラー２２の位置には、走行レール１６、１７の外周と平行してガイドレール１９が延設されており、これにより停留場１１、１２で進行する搬器１８の姿勢が一定に保たれる。ガイドレール１９の下部に沿っては、通電された給電レール２３が敷設されており、一方、握索機２０には給電レール２３に接触する集電子２４を備えている。集電子２４には電線ケーブル２５が接続されており、電線ケーブル２５の他端は搬器１８内の蓄電池２６に接続されている。停留場１１、１２内においては、給電レール２３と集電子２４とが接触して移動し、この間に搬器１８側へ電力が供給され蓄電池２６が充電される。   FIG. 2 shows a part of the stops 11 and 12. The grinder 20 of the transporter 18 includes a traveling roller 21 that rolls on the traveling rails 16 and 17, and an end roller 22 at the end opposite to the traveling roller 21. At the position of the end roller 22, a guide rail 19 is extended in parallel with the outer periphery of the traveling rails 16, 17, and thereby the attitude of the transporter 18 traveling in the stop areas 11, 12 is kept constant. A power supply rail 23 that is energized is laid along the lower portion of the guide rail 19, while the grinder 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 transporter 18. In the stops 11 and 12, the power supply rail 23 and the current collector 24 move in contact with each other, and during this time, power is supplied to the transporter 18 and the storage battery 26 is charged.

給電レール２３の両端部付近（図１参照）には、非接触で搬器１８の握索機２０の通過を検出する搬器検出器２７を備えている。搬器検出器２７は、近接スイッチや光電センサ等であって、握索機２０を検知していないときはＯＦＦとなっており、握索機２０を検知するとＯＮとなる。このような構成により搬器検出器２７ないし給電レール２３は以下のように動作する。   In the vicinity of both ends of the power supply rail 23 (see FIG. 1), a portable detector 27 that detects the passage of the gripping device 20 of the portable device 18 in a non-contact manner is provided. The carrier detector 27 is a proximity switch, a photoelectric sensor, or the like, and is OFF when the gripping device 20 is not detected, and is ON when the gripping device 20 is detected. With this configuration, the transport detector 27 or the power supply rail 23 operates as follows.

まず、搬器１８が停留場１１、１２に到着していないときには、搬器検出器２７はＯＦＦの状態であり、また、給電レール２３への通電は遮断された状態である。搬器１８が停留場１１、１２に到着して索条１５から切り離されて進行すると、まず、給電レール２３と搬器１８の集電子２４とが接触する。このときに給電レール２３には通電されていないので、給電レール２３と集電子２４との間でスパークが発生することはない。次いで、握索機２０が搬器検出器２７の位置に到達すると搬器検出器２７がＯＮとなり、この信号により給電レール２３への通電が開始される。これにより集電子２４を介して搬器１８の蓄電池２６へ電力が供給され、搬器１８が停留場１１、１２内を移動する間に蓄電池２６が充電される。   First, when the transporter 18 has not arrived at the stops 11 and 12, the transporter detector 27 is in an OFF state, and the power supply to the power supply rail 23 is interrupted. When the transporter 18 arrives at the stops 11 and 12 and is separated from the cable 15 and proceeds, first, the power supply rail 23 and the current collector 24 of the transporter 18 come into contact with each other. At this time, since the power supply rail 23 is not energized, no spark is generated between the power supply rail 23 and the current collector 24. Next, when the grinder 20 reaches the position of the carrier detector 27, the carrier detector 27 is turned on, and the energization to the power supply rail 23 is started by this signal. As a result, electric power is supplied to the storage battery 26 of the transporter 18 via the current collector 24, and the storage battery 26 is charged while the transporter 18 moves in the stops 11 and 12.

次ぎに、搬器１８が出発側へ移動し握索機２０が出発側の搬器検出器２７の位置に達すると、搬器検出器２７が握索機２０を検知してＯＮとなり、この信号により給電レール２３への通電を遮断する。このとき給電レール２３と集電子２４は、接触した状態を保っている。次いで、握索機２０が移動するのにともなって給電レール２３と集電子２４とが離脱し、給電レール２３への通電は遮断された状態で保持される。   Next, when the carrier 18 moves to the departure side and the grinder 20 reaches the position of the departure-side carrier detector 27, the carrier detector 27 detects the grasper 20 and is turned on. The power supply to 23 is cut off. At this time, the power supply rail 23 and the current collector 24 are kept in contact with each other. Next, as the grinder 20 moves, the power supply rail 23 and the current collector 24 are separated from each other, and the power supply to the power supply rail 23 is held in an interrupted state.

このように、給電レール２３と集電子２４とが接触する瞬間および離脱する瞬間には給電レール２３に通電されておらず、給電レール２３と集電子２４とが接触した状態で通電および通電遮断が行われるので、急速充電のように大電流を通電する場合であっても給電レール２３と集電子２４間でのスパークの発生を防止することができる。また、握索機２０検出信号のみで給電レール２３への通電および通電遮断を行うので複雑な制御機器等を必要とせず、このため確実に給電レール２３への通電および通電遮断を行うことができる。   Thus, at the moment when the power supply rail 23 and the current collector 24 are in contact with each other and at the moment of separation, the power supply rail 23 is not energized, and the power supply rail 23 and the current collector 24 are in contact with each other. Thus, even when a large current is applied like rapid charging, the occurrence of sparks between the power supply rail 23 and the current collector 24 can be prevented. Further, since the energization and de-energization of the power supply rail 23 are performed only by the grinder 20 detection signal, no complicated control device or the like is required, and therefore the energization and de-energization of the power supply rail 23 can be reliably performed. .
