Description

本発明は、定置式の軌道に沿って走行する軌道車両の制動エネルギ回収装置およびそれを用いる輸送システムに関するものである。   The present invention relates to a braking energy recovery device for a track vehicle that travels along a stationary track and a transportation system using the same.

この種の軌道車両として、遊園地などに設置されるジェットコースタが従来よりあった（例えば特許文献１参照）。またジェットコースタのように位置エネルギを利用して、駅間に敷設された軌道上を走行する無人の軌道車両を用いた輸送システムが提案されている。   Conventionally, there has been a roller coaster installed in an amusement park or the like as this type of track vehicle (see, for example, Patent Document 1). In addition, a transportation system using an unmanned track vehicle that travels on a track laid between stations using potential energy like a roller coaster has been proposed.

このような軌道車両では、軌道車両自体に自走するための動力源を備えておらず、軌道に設けた定置式の駆動装置により加速させられ、その後は駆動装置から与えられたエネルギにより運動エネルギを得て、目的地点まで走向するようになっていた。また、急勾配の上り勾配区間と、上り区間を越えたあとの下り勾配区間とを軌道に設け、上り勾配区間に設けられた定置式の引き上げ装置により軌道車両に上り勾配区間を上らせ、その後の下り勾配区間を軌道車両に滑走走行させることで、軌道車両を目的地点まで走行させるものもあった。
特開２０００−１６８５５３号公報（段落［０００８］−［００２４］、及び、第３図） In such a track vehicle, the track vehicle itself is not provided with a power source for self-running, and is accelerated by a stationary drive device provided on the track, and thereafter the kinetic energy is generated by the energy given from the drive device. I got to get to the destination point. In addition, a steep ascending slope section and a descending slope section after exceeding the ascending section are provided on the track, and the orbiting vehicle is raised by the stationary lifting device provided in the ascending slope section, In some cases, the track vehicle is caused to travel to the destination point by causing the track vehicle to run on the descending slope section thereafter.
JP 2000-168553 A (paragraphs [0008]-[0024] and FIG. 3)

上述の軌道車両では、外部の駆動装置によって加速させられたり、引き上げ装置によって位置エネルギを与えられると、以後は起動時に与えられたエネルギにより無人で自走するため、軌道車両が目的地まで到達した際に軌道車両に制動をかける制動装置を軌道側に設ける必要があった。また、上り勾配区間の後に設けた下り勾配区間を滑走走行させるシステムでは、地形的な理由によって急勾配が発生し、それによって軌道車両の速度が急激に増加する場合もあるが、乗客を輸送する輸送システムでは急加速によって乗客に不快感を与えるため、速度が急激に増加する区間には軌道車両に制動をかける制動装置を軌道側に設置して、軌道車両の速度を抑える必要があった。   In the above-mentioned track vehicle, when accelerated by an external driving device or given potential energy by a lifting device, the track vehicle reaches the destination because it will run unattended by the energy given at the time of startup. In this case, it is necessary to provide a braking device for braking the track vehicle on the track side. In addition, in a system in which a down slope section provided after an up slope section is run, a steep slope is generated due to topographical reasons, and the speed of the track vehicle may increase rapidly. In order to give passengers discomfort due to sudden acceleration in the transportation system, it was necessary to install a braking device for braking the track vehicle on the track side to suppress the speed of the track vehicle in a section where the speed rapidly increases.

そこで、従来は、走向方向に沿わせて軌道車両に制動板を設けるとともに、軌道の減速区間に、制動板を両面から挟圧するブレーキシューを配置してあり、ブレーキシューを制動板に押し当てた際に発生する摩擦力で制動をかけるようになっていた。この場合、軌道車両を制動する際に、軌道車両のもつ速度エネルギーが熱エネルギーとして消費されるだけなので、軌道車両のもつ速度エネルギーを有効に利用することができなかった。   Therefore, conventionally, a brake plate is provided on the track vehicle along the direction of travel, and a brake shoe that clamps the brake plate from both sides is arranged in the deceleration section of the track, and the brake shoe is pressed against the brake plate. The brakes were applied by the frictional force generated at the time. In this case, when braking the track vehicle, the velocity energy of the track vehicle is only consumed as thermal energy, so that the velocity energy of the track vehicle cannot be used effectively.

一方、走行のための動力源として電動機を備えた電車では、制動時に電動機を発電機として動作させ、運動エネルギーを電気エネルギーに変換することによって、制動エネルギを回収しているが、車体に電動機を搭載しているため、車体が大型化したり、重量が重くなり、軌道などの関連施設を含めた全体の建設費が高騰するという問題があった。   On the other hand, in a train equipped with an electric motor as a power source for running, the braking energy is recovered by operating the electric motor as a generator during braking and converting kinetic energy into electric energy. As a result, the vehicle body becomes larger and heavier, and the overall construction cost including related facilities such as tracks has risen.

本発明は上記問題点に鑑みて為されたものであり、その目的とするところは、制動時に失われる速度エネルギーを回収して有効に利用できる安価な軌道車両の制動エネルギ回収装置およびを提供することにある。   The present invention has been made in view of the above problems, and an object thereof is to provide an inexpensive braking energy recovery device for a track vehicle that can recover and effectively use speed energy lost during braking. There is.

上記目的を達成するために、請求項１の発明は、軌道車両の制動エネルギ回収装置に関するものであって、軌道上を走行する軌道車両の制動エネルギ回収装置であって、走向方向に沿うようにして軌道車両に取り付けられた制動板と、軌道の減速区間に配置され制動板に周面が当接することによって回転駆動される回転体と、回転体の回転に応じて回転軸が回転し、回転軸の回転数に応じた電気エネルギを発電する発電機とを備えて成ることを特徴とする。   In order to achieve the above object, the invention of claim 1 relates to a braking energy recovery device for a track vehicle, which is a braking energy recovery device for a track vehicle that travels on a track, and is adapted to be along a running direction. The brake plate attached to the track vehicle, the rotating body that is arranged in the deceleration section of the track and is driven to rotate by contacting the peripheral surface with the brake plate, and the rotating shaft rotates and rotates according to the rotation of the rotating body And a generator for generating electrical energy corresponding to the rotational speed of the shaft.

請求項２の発明は、単線の軌道に沿って設置した駅の間を軌道車両が走行する輸送システムであって、単線の軌道は、該軌道の駅近傍区間であって軌道定置式の駆動装置にて軌道車両を加速する加速区間と、該加速ゾーンで加速された軌道車両が自走する自走区間と、軌道車両を減速する減速区間とを少なくとも有し、走向方向に沿うようにして軌道車両に制動板を取り付けるとともに、軌道の減速区間に、制動板に周面が当接することによって回転駆動される回転体と、回転体の回転に応じて回転軸が回転し、回転軸の回転数に応じた電気エネルギを発電する発電機とを配設したことを特徴とする。   The invention of claim 2 is a transportation system in which a rail vehicle runs between stations installed along a single track, and the single track is a section near the station of the track and is a stationary drive device. At least an acceleration section for accelerating the track vehicle, a self-run section in which the track vehicle accelerated in the acceleration zone self-runs, and a deceleration section for decelerating the track vehicle, and running along the strike direction A brake plate is attached to the vehicle, and the rotating body is driven to rotate when the peripheral surface abuts on the brake plate in the deceleration section of the track, and the rotating shaft rotates according to the rotation of the rotating body. And a generator for generating electrical energy according to the above.

請求項１の発明によれば、軌道を走行する軌道車両に設けた制動板が、軌道の減速区間に設置された回転体の周面に当接して回転体を回転させることで、電動機の回転軸が回転駆動されて、電動機が回転軸の回転数に応じた電気エネルギを発生するので、軌道車両のもつ速度エネルギを電気エネルギに変換することによって、軌道車両を減速させることができ、且つ、減速によって失われる速度エネルギを電気エネルギとして有効に利用できるという効果がある。   According to the first aspect of the invention, the braking plate provided on the track vehicle traveling on the track makes contact with the peripheral surface of the rotating body installed in the deceleration section of the track and rotates the rotating body, thereby rotating the motor. The shaft is driven to rotate, and the electric motor generates electric energy according to the number of rotations of the rotating shaft. Therefore, by converting the speed energy of the track vehicle into electrical energy, the track vehicle can be decelerated, and There is an effect that speed energy lost by deceleration can be effectively used as electric energy.

請求項２の発明によれば、軌道車両を減速させることによって失われる速度エネルギを電気エネルギとして有効に利用できる輸送システムを実現できるという効果がある。   According to the invention of claim 2, there is an effect that it is possible to realize a transportation system that can effectively use the speed energy lost by decelerating the track vehicle as electric energy.

以下では、本発明に係る軌道車両の制動エネルギ回収装置を輸送システムに適用した一実施形態について図面を参照して説明する。   Hereinafter, an embodiment in which a braking energy recovery device for a track vehicle according to the present invention is applied to a transportation system will be described with reference to the drawings.

図３は本実施形態の輸送システムの軌道配設図であり、単線の軌道１に沿って２つの駅２ａ，２ｂを設けてあり、軌道１上を走行する軌道車両３が駅２ａ，２ｂ間を往復するようになっている。ここにおいて、単線の軌道１は、各駅２ａ，２ｂから出発した軌道車両３が軌道定置式の駆動装置によって加速される加速区間Ａ１，Ａ２と、加速区間Ａ１，Ａ２で加速された軌道車両３が加速区間Ａ１，Ａ２で与えられた走行エネルギのみで次駅２ｂまで走行する自走区間Ｂとで構成されており、各駅２ａ，２ｂ…毎に加速区間Ａ１，Ａ２が設けられている。   FIG. 3 is a track arrangement diagram of the transportation system of the present embodiment, in which two stations 2a and 2b are provided along a single track 1, and the track vehicle 3 traveling on the track 1 is between the stations 2a and 2b. To come and go. Here, the track 1 of the single line is composed of an acceleration section A1, A2 in which the track vehicle 3 starting from each station 2a, 2b is accelerated by a track stationary drive device, and a track vehicle 3 accelerated in the acceleration section A1, A2. It consists of a self-propelled section B that travels to the next station 2b only with the travel energy given in the acceleration sections A1 and A2, and an acceleration section A1, A2 is provided for each station 2a, 2b.

ここで、本実施形態の輸送システムでは、上記加速ゾーンとして、電磁力により軌道車両３を加速するリニア式加速ゾーンＡ１と、軌道車両３に位置エネルギを与え、位置エネルギを運動エネルギに変換することで軌道車両３を加速するコースター式加速ゾーンＡ２とを採用している。リニア式加速ゾーンＡ１では軌道１が略水平に形成され、軌道１側に設置した電磁石装置４（図５参照）と、車両３に備えた永久磁石よりなる可動磁石体５（図５参照）との間に作用する電磁力によって、軌道車両３に推進力を加えて軌道車両３を加速するようになっている。またコースター式加速ゾーンＡ２では軌道１に急勾配の勾配区間を設け、勾配区間に設けた引揚装置（図示省略）にて軌道車両３を引き上げ、勾配区間の上側に登らせることによって、軌道車両３に位置エネルギを与えた後、勾配区間を軌道車両３が滑り降りることで、位置エネルギを運動エネルギに変換して軌道車両３を加速するようになっている。具体的には、軌道１において駅２ａに対して駅２ｂ側の近傍区間にはリニア式加速ゾーンＡ１が、駅２ｂに対して駅２ａと反対側の近傍区間にはコースター式加速ゾーンＡ２がそれぞれ設けられており、加速ゾーンＡ１，Ａ２の間が自走ゾーンＢとなっている。なお、コースター式加速ゾーンＡ２の引揚装置としては、例えばチェーンと減速機付きモータ、又は、ロープと巻取装置と減速機付きモータと昇降台等から構成されている。   Here, in the transportation system of the present embodiment, as the acceleration zone, a linear acceleration zone A1 that accelerates the track vehicle 3 by electromagnetic force, and potential energy is applied to the track vehicle 3, and the potential energy is converted into kinetic energy. The coaster type acceleration zone A2 for accelerating the track vehicle 3 is adopted. In the linear acceleration zone A1, the track 1 is formed substantially horizontally, an electromagnet device 4 (see FIG. 5) installed on the track 1 side, and a movable magnet body 5 (see FIG. 5) made of a permanent magnet provided in the vehicle 3. The track vehicle 3 is accelerated by applying a propulsive force to the track vehicle 3 by electromagnetic force acting between the track vehicle 3 and the track vehicle 3. In the coaster type acceleration zone A2, a steep gradient section is provided on the track 1, the track vehicle 3 is lifted by a lifting device (not shown) provided in the gradient section, and is moved up to the gradient section. After applying the potential energy to the track vehicle, the track vehicle 3 slides down the gradient section, thereby converting the position energy into kinetic energy and accelerating the track vehicle 3. Specifically, on track 1, linear acceleration zone A1 is in the vicinity section on the station 2b side with respect to station 2a, and coaster acceleration zone A2 is in the vicinity section on the opposite side to station 2a with respect to station 2b. A self-propelled zone B is provided between the acceleration zones A1 and A2. Note that the lifting device of the coaster type acceleration zone A2 includes, for example, a chain and a motor with a speed reducer, or a rope, a winding device, a motor with a speed reducer, and a lifting platform.

このような輸送システムにおいて、駅２ａと駅２ｂの間で軌道車両３を往復させるには、下記のように運行すれば良い。なお、図４に示すように複数両の軌道車両３が連結された連結車両を軌道１上に走行させるようにしても良いし、軌道車両３を１両のみで走行させるようにしても良い。   In such a transport system, in order to reciprocate the track vehicle 3 between the station 2a and the station 2b, the train may be operated as follows. As shown in FIG. 4, a connected vehicle in which a plurality of track vehicles 3 are connected may be run on the track 1, or the track vehicle 3 may be run by only one vehicle.

まず、一方の駅２ａから他方の駅２ｂに軌道車両３を走らせるには、駅２ａから駅２ｂに向けて軌道車両３を発車させ、この軌道車両３をリニア式加速ゾーンＡ１で加速させ、この加速された軌道車両３をそのまま自走ゾーンＢに滑らせて他方の駅２ｂに至らせるようにしている。また、他方の駅２ｂから一方の駅２ａに軌道車両３を走らせるには、一旦、駅２ｂから駅２ａと反対側に向けて軌道車両３を発車させ、この軌道車両３をコースター式加速ゾーンＡ２に引き揚げた後、軌道車両３を下り勾配に沿わせて滑落させることで加速させ、この加速された軌道車両３をそのまま自走ゾーンＢに滑らせて駅２ａに至らせるようにしている。   First, in order to run the rail vehicle 3 from one station 2a to the other station 2b, the rail vehicle 3 is departed from the station 2a toward the station 2b, and the rail vehicle 3 is accelerated in the linear acceleration zone A1, The accelerated track vehicle 3 is slid to the self-propelled zone B as it is to reach the other station 2b. Further, in order to run the rail vehicle 3 from the other station 2b to the one station 2a, the rail vehicle 3 is once departed from the station 2b toward the opposite side of the station 2a, and the rail vehicle 3 is set in a coaster type acceleration zone. After being pulled up to A2, the track vehicle 3 is accelerated by sliding down along a downward slope, and the accelerated track vehicle 3 is slid to the self-propelled zone B as it is to reach the station 2a.

そして、滑走走行してきた軌道車両３を駅２ａ，２ｂで停止させる際には、軌道車両３を減速させる必要があり、本システムでは図３に示すように駅２ａ，２ｂの手前側に減速区間Ｄを設けて、減速区間Ｄに進入してきた軌道車両３を減速させた後、駅２ａ，２ｂに設けた制動停止区間Ｃで制動をかけて軌道車両３を停止させるようになっている。   Then, when stopping the track vehicle 3 that has been running at the stations 2a and 2b, it is necessary to decelerate the track vehicle 3, and in this system, as shown in FIG. 3, a deceleration zone is provided in front of the stations 2a and 2b. After D is provided and the track vehicle 3 entering the deceleration zone D is decelerated, the track vehicle 3 is stopped by applying braking in the braking stop zone C provided at the stations 2a and 2b.

図１（ａ）（ｂ）及び図６に示すように軌道車両３の車体下面には、走向方向を長手方向とする矩形板状の制動板４０が突設されている。   As shown in FIGS. 1A and 1B and FIG. 6, a rectangular plate-like braking plate 40 having a running direction as a longitudinal direction is projected from the lower surface of the track vehicle 3.

一方、軌道１の減速区間Ｄには、図１及び図７に示すように、周面が当接することによって回転駆動される回転体としての制動タイヤ４１が、制動板４０の両側面に対向し、且つ、走行方向において所定の間隔を開けて複数（本実施形態では片面に４個ずつ）配置されるとともに、各制動タイヤ４１の回転に応じて回転軸４２が回転し、回転軸４２の回転数に応じた電気エネルギを発電する複数台（例えば８台）の発電機４３が設けられている。なお制動板４０の両側に配置される各２個の制動タイヤ４１は、制動板４０を間にしてそれぞれ対向する位置に配置されている。   On the other hand, in the deceleration section D of the track 1, as shown in FIGS. 1 and 7, braking tires 41 as rotating bodies that are rotationally driven by contacting the peripheral surfaces face both side surfaces of the braking plate 40. In addition, a plurality of (four in one embodiment in this embodiment) are arranged at predetermined intervals in the traveling direction, and the rotating shaft 42 rotates in accordance with the rotation of each brake tire 41, and the rotating shaft 42 rotates. A plurality of (for example, eight) generators 43 that generate electric energy corresponding to the number are provided. The two brake tires 41 arranged on both sides of the brake plate 40 are arranged at positions facing each other with the brake plate 40 in between.

また、軌道１の制動停止区間Ｄには、図６及び図７に示すように駅２のプラットホーム２ａ付近に、制動板４０を挟んで左右両側に制動板４０を挟圧するブレーキシュー２０と、制動板４０に当接する位置と制動板４０から離れる位置との間でブレーキシュー２０を進退させるアクチュエータ２１とが配置されている。   Further, in the braking stop section D of the track 1, as shown in FIGS. 6 and 7, a brake shoe 20 that sandwiches the brake plate 40 on both the left and right sides with the brake plate 40 sandwiched near the platform 2 a of the station 2, An actuator 21 for moving the brake shoe 20 back and forth is disposed between a position where it abuts on the plate 40 and a position away from the brake plate 40.

そして、駅２に向かって自走してきた軌道車両３を減速、停止させる場合、先ず軌道車両３が減速区間Ｄに入ってくると、軌道車両３の制動板４０が制動タイヤ４１，４１の間に進入するので、制動タイヤ４１の周面が制動板４０に当接することによって制動タイヤ４１が回転させられ、制動タイヤ４１の回転数に応じた交流の電気エネルギを発電機４３が発電する。図２は制動エネルギ回収装置の回路図であり、発電機４３により発電された回生電力はインバータ４４により直流電圧に変換され、昇圧チョッパ４５により所望の電圧値に昇圧された後、バッテリなどの蓄電装置４６に蓄電されるようになっており、この蓄電装置４６に蓄電されたエネルギを、駅２ａ，２ｂ内の照明などの電源や、軌道車両３を加速するための電磁石装置４或いは引揚装置の電源として利用することができる。ここに、軌道車両３に設けた制動板４０、制動タイヤ４１、発電機４３、インバータ４４、昇圧チョッパ４５および蓄電装置４６などから制動エネルギ回収装置が構成されるのである。   And when decelerating and stopping the track vehicle 3 that has been traveling toward the station 2, when the track vehicle 3 first enters the deceleration section D, the brake plate 40 of the track vehicle 3 is positioned between the braking tires 41, 41. Therefore, the braking tire 41 is rotated when the peripheral surface of the braking tire 41 abuts against the braking plate 40, and the generator 43 generates AC electrical energy corresponding to the rotational speed of the braking tire 41. FIG. 2 is a circuit diagram of the braking energy recovery device. Regenerative power generated by the generator 43 is converted into a DC voltage by the inverter 44 and boosted to a desired voltage value by the boost chopper 45 and then stored in a battery or the like. The energy stored in the power storage device 46 is stored in the power source 46 such as lighting in the stations 2a and 2b, the electromagnetic device 4 for accelerating the track vehicle 3, or the lifting device. It can be used as a power source. Here, the braking energy recovery device is constituted by the braking plate 40, the braking tire 41, the generator 43, the inverter 44, the boost chopper 45, the power storage device 46, and the like provided in the track vehicle 3.

その後、減速区間Ｄで減速された軌道車両３が駅２に入り、所定の停止位置（プラットホーム２ａの乗降場所と軌道車両３の出入口が一致する位置）まで走行すると、アクチュエータ２１がブレーキシュー２０を軌道車両３の制動板４０に挟圧することで、軌道車両３を制動し、所望の停止位置で軌道車両３を停止させるのである。なお、駅２に停止した軌道車両３が走行を開始する際には、アクチュエータ２１がブレーキシュー２０を制動板４０から離れる位置に駆動するので、軌道車両３に制動力が加えられることは無い。   After that, when the track vehicle 3 decelerated in the deceleration zone D enters the station 2 and travels to a predetermined stop position (a position where the platform 2a boarding / alighting position coincides with the entrance / exit of the track vehicle 3), the actuator 21 moves the brake shoe 20 over. By clamping the brake plate 40 of the track vehicle 3, the track vehicle 3 is braked and the track vehicle 3 is stopped at a desired stop position. When the track vehicle 3 stopped at the station 2 starts traveling, the actuator 21 drives the brake shoe 20 to a position away from the brake plate 40, so that no braking force is applied to the track vehicle 3.

以上説明したように、本実施形態の制動エネルギ回収装置では、減速区間Ｄに進入してきた軌道車両３の制動板４０が制動タイヤ４１，４１の間に進入すると、制動タイヤ４１の周面が制動板４０に当接することによって制動タイヤ４１が回転させられ、制動タイヤ４１の回転数に応じた電気エネルギを発電機４３が発生し、この電気エネルギが蓄電装置４６に蓄電されるので、軌道車両３のもつ速度エネルギを電気エネルギに変換することによって、軌道車両を減速させることができ、また減速によって失われる速度エネルギを電気エネルギに変換し、蓄電装置４６に蓄電することで有効に利用することができる。   As described above, in the braking energy recovery device of the present embodiment, when the braking plate 40 of the track vehicle 3 that has entered the deceleration zone D enters between the braking tires 41, 41, the peripheral surface of the braking tire 41 is braked. Since the braking tire 41 is rotated by coming into contact with the plate 40, the generator 43 generates electrical energy corresponding to the number of rotations of the braking tire 41, and this electrical energy is stored in the power storage device 46. It is possible to decelerate the track vehicle by converting the speed energy of the vehicle into electric energy, and to convert the speed energy lost by the deceleration into electric energy and store it in the power storage device 46 for effective use. it can.

尚、本実施形態では駅２ａ，２ｂの近傍を減速区間Ｄとし、該減速区間Ｄに制動エネルギ回収装置を設置した例について説明したが、駅２ａ，２ｂの間の自走区間Ｂなどで軌道車両３の急加速や速度超過を防止するために必要な区間に上記の制動エネルギ回収装置を設けても良いことは言うまでもない。   In the present embodiment, an example in which the vicinity of the stations 2a and 2b is set as the deceleration section D and the braking energy recovery device is installed in the deceleration section D has been described, but the track travels in the self-propelled section B between the stations 2a and 2b. Needless to say, the braking energy recovery device described above may be provided in a section necessary for preventing the vehicle 3 from suddenly accelerating or exceeding the speed.

ところで本実施形態の輸送システムでは、それぞれの駅２ａ，２ｂを発車した軌道車両３が軌道定置式の駆動装置（電磁石装置４や引揚装置など）を備えた加速ゾーンＡ１，Ａ２によって加速されるようになっている。一般に軌道車両３の走行にあっては、停車時からの加速に最も大きな駆動力を必要とするのであるが、本実施形態の輸送システムでは軌道１側に設けた定置式の駆動装置により軌道車両３を加速し、以後は加速ゾーンＡ１，Ａ２で与えられた運動エネルギにより軌道車両３が自走するようになっているので、軌道車両３自体に、停車時からの加速に必要な大きな動力源を備える必要が無く、つまり自走走行に必要な大型の動力源を軌道車両３に備える必要がないため、軌道車両３の小型化、軽量化が図れるようされているのである。これによると、軌道１が単線であることで得られる輸送システム敷設にかかる必要面積の縮小効果を更に図ることができて、更なる狭小地への建設も可能にするものであり、また、これに加えて軌道車両３や軌道１を支持する支持脚６等に求める耐荷重性能も低減でき、併せて、建設コストの大幅な低廉化を図ることができるようになっているのである。なお、本実施形態では加速ゾーンとしてリニア式加速ゾーンＡ１とコースター式加速ゾーンＡ２とを採用しているが、図８に示すようにコースター式加速ゾーンＡ２のみで加速ゾーンを構成しても良いし、図９に示すようにリニア式加速ゾーンＡ１のみで加速ゾーンを構成しても良い。また、本実施形態では２つの駅２ａ，２ｂの間を往復する場合について説明を行ったが、軌道１に沿って３つ以上の駅２ａ，２ｂ…を設け、軌道１を往復することによって駅２ａ，２ｂ…間を運行するようにしても良い。また、軌道１を環状として、軌道１を一方向或いは往復走行し、軌道１に沿って設けた複数の駅２ａ…の間を移動するようにしても良い。   By the way, in the transport system of the present embodiment, the rail vehicle 3 that departs from each of the stations 2a and 2b is accelerated by acceleration zones A1 and A2 each having a track stationary drive device (such as an electromagnet device 4 and a lifting device). It has become. In general, when the track vehicle 3 travels, the greatest driving force is required for acceleration after the vehicle stops. In the transportation system of this embodiment, the track vehicle is driven by a stationary drive device provided on the track 1 side. Since the track vehicle 3 is allowed to self-propelled by the kinetic energy given in the acceleration zones A1 and A2, the track vehicle 3 itself has a large power source necessary for acceleration from the time of stopping. Therefore, it is not necessary to provide the track vehicle 3 with a large power source necessary for self-propelled traveling, so that the track vehicle 3 can be reduced in size and weight. According to this, it is possible to further reduce the required area required for laying the transportation system obtained by the track 1 being a single wire, and to enable further construction in a narrow area. In addition, the load bearing performance required for the track vehicle 3 and the support legs 6 that support the track 1 can be reduced, and at the same time, the construction cost can be greatly reduced. In this embodiment, the linear acceleration zone A1 and the coaster acceleration zone A2 are adopted as the acceleration zones. However, as shown in FIG. 8, the acceleration zone may be configured only by the coaster acceleration zone A2. As shown in FIG. 9, the acceleration zone may be constituted by only the linear acceleration zone A1.

You may make it operate | move between 2a, 2b .... Alternatively, the track 1 may be circular, and the track 1 may travel in one direction or reciprocatingly so as to move between a plurality of stations 2 a provided along the track 1.

以上に概要を示した本実施形態の輸送システムにあっては、軌道１上を走行する軌道車両３の安全性や、快適な乗り心地も確保されており、以下に走行装置の構成を詳述する。   In the transportation system of the present embodiment as outlined above, the safety of the track vehicle 3 traveling on the track 1 and a comfortable ride are ensured, and the configuration of the traveling device will be described in detail below. To do.

図５に示すように、軌道１は、主桁７と、その上方の左右に配設された丸パイプ鋼材の２本の軌条８と、主桁７とこの２本の軌条８を連結するように所定ピッチに配設された連結部材９とを、有して構成されている。軌道車両３は、各軌条８を、上方・側方・下方から接触して転動する上輪１０、横輪１１、下輪１２を有している。上輪１０は車両重量を支持する主車輪であり、横輪１１は側方ガイド車輪であり、下輪１２は浮き上がり防止車輪であるといえる。而して図５中左側の軌条８を上輪１０、横輪１１、下輪１２にて上側、左側、下側の３方向から抱え込むとともに、図中右側の軌条８を上輪１０、横輪１１、下輪１２にて上側、右側、下側の３方向から抱え込むことによって、どのような傾斜、曲線の軌道１でも軌道車両３が軌道１から脱線する虞を無くしているのであり、輸送システムの安全性が確保されている。なお、上輪１０、横輪１１、下輪１２はウレタン等の弾性材質の車輪としてあり、軌道１を走行する際の軌道車両３の振動を抑えて快適な乗り心地を確保すると共に、走行騒音も無くして騒音公害の防止も図られている。   As shown in FIG. 5, the track 1 connects the main girder 7, the two rails 8 of the round pipe steel material disposed on the left and right above the main girder 7, and the main girder 7 and the two rails 8. And connecting members 9 disposed at a predetermined pitch. The track vehicle 3 has an upper wheel 10, a lateral wheel 11, and a lower wheel 12 that roll while contacting each rail 8 from above, from the side, and from below. It can be said that the upper wheel 10 is a main wheel that supports the vehicle weight, the horizontal wheel 11 is a side guide wheel, and the lower wheel 12 is a lift-off preventing wheel. Thus, the rail 8 on the left side in FIG. 5 is held by the upper wheel 10, the lateral wheel 11, and the lower wheel 12 from the three directions of the upper side, the left side, and the lower side, and the right rail 8 in FIG. By holding the lower wheel 12 in the three directions of the upper side, right side, and lower side, it is possible to eliminate the possibility that the track vehicle 3 derails from the track 1 at any inclination and curve of the track 1. Is secured. Note that the upper wheel 10, the horizontal wheel 11, and the lower wheel 12 are wheels made of an elastic material such as urethane, which suppresses vibration of the track vehicle 3 when traveling on the track 1 to ensure a comfortable riding comfort, and also generates traveling noise. Eliminating noise pollution is also attempted.

なお、図５に示すように軌道１側には給電設備２３が設けられている。この給電設備２３は、軌道車両３側の集電子（図示せず）に摺接させることで軌道車両３側の電源回路に電気的に接続されるようになっている。たとえば、駅舎内の軌道１に給電設備２３を備えておき、軌道車両３にバッテリー（図示せず）を備えておくと、駅停車中に集電子を介して軌道車両３に確実に電気を供給させることができ、この電気が充電されたバッテリーによる給電によって、車内照明や空調装置２４等を動作させるようにできるのである。   As shown in FIG. 5, a power feeding facility 23 is provided on the track 1 side. The power supply facility 23 is electrically connected to a power supply circuit on the track vehicle 3 side by being brought into sliding contact with a current collector (not shown) on the track vehicle 3 side. For example, if the track 1 in the station building is provided with the power supply facility 23 and the track vehicle 3 is provided with a battery (not shown), electricity is reliably supplied to the track vehicle 3 via the current collector while the station stops. The interior lighting, the air conditioner 24, and the like can be operated by power feeding by a battery charged with electricity.

尚、本実施形態では軌道車両の制動エネルギ回収装置を輸送システムに適用した形態について説明を行ったが、遊園地などに設置され、急勾配の上り勾配を有する軌道を軌道車両に登らせて位置エネルギを与えた後、下り勾配を滑り下りさせることで位置エネルギを運動エネルギに変換して、軌道車両を自走させるようなコースタ装置に上記の制動エネルギ回収装置を適用しても良い。   In the present embodiment, the mode in which the braking energy recovery device for the track vehicle is applied to the transportation system has been described. However, the track vehicle is installed in an amusement park or the like, and the track having a steep upward slope is climbed on the track vehicle. After applying energy, the braking energy recovery device described above may be applied to a coaster device in which the potential energy is converted into kinetic energy by sliding down a descending slope and the track vehicle is self-propelled.
