Description

本発明は、低床ＬＲＶ用レール集電用接触子に関するものである。 The present invention relates to a rail current collector for contacts for low floor LRV.

現在開発中であるバッテリ式低床ＬＲＶ（Ｌｉｇｈｔ Ｒａｉｌ Ｖｅｈｉｃｌｅ）は、運行中の停車時間内に時折急速充電を行う必要がある。ここで、専用の充電設備を高電圧化して構築すれば、大電流の充電が可能であり、給電設備（架線やレール）との接触子構造も簡便にすることができるが、地上設備が高価となったり、絶縁離隔等で設置上の制約が生ずるといった問題がある。   The battery-type low-floor LRV (Light Rail Vehicle) currently under development needs to be quickly charged within the stoppage time during operation. Here, if a dedicated charging facility is constructed with a high voltage, it is possible to charge a large current and the contactor structure with the power supply facility (overhead wire or rail) can be simplified, but the ground facility is expensive. There is a problem that there are restrictions on installation due to insulation separation or the like.

一方、直流６００ボルト程度の低電圧給電設備とした場合には、地上設備は簡易になり、路面電化区間の電化設備等とも共通性が得られる面があるが、地上設備と車両間で停車時に短時間に高電流授受を行う必要が生ずる。
通常の電化区間列車の集電系は、走行中集電が普通であって、このような停車中の短時間大電流集電というものはあまり例がなく、かかる停車中の短時間大電流集電を行おうとすると、マイナス帰線接地側となる車輪レールの点接触部位が溶着（スポット溶接に近い）したり、車両軸受けの電食発熱や溶着が発生することも懸念される。
なし On the other hand, in the case of a low-voltage power supply facility of about 600 volts DC, the ground facility is simplified, and there is a commonality with the electrification facility of the road surface electrification section, but when the vehicle stops between the ground facility and the vehicle It is necessary to exchange high current in a short time.
Normally, the current collection system of electrified section trains collects electricity while traveling, and there is no such a short-time high-current collection during such a stop. If electricity is to be generated, there is a concern that the point contact portion of the wheel rail on the negative return grounding side may be welded (similar to spot welding), or the electric corrosion heat generation or welding of the vehicle bearing may occur.
None

1 is an overall side view of a low floor LRV showing an embodiment of the present invention, FIG. 2 is a front view of the low floor LRV, and FIG. 3 is a diagram of a contact for collecting low voltage and high current rail for the low floor LRV. FIG. 4 is a schematic diagram, and FIG. 4 is a diagram showing an example of a charging overhead line in a short section at a stop for supplying power to the low floor LRV.
In these drawings, 1 is a rail, 2 is a low-floor LRV, 3 is a carriage, 4 is a contact surface (copper-based material made of copper material) arranged at the lower part of the central portion of the side beam of the carriage frame 3A of the carriage 3. In the case of about 500 mm 2 or more, in the case of carbon-based material, about 5000 mm 2 of rail current collecting contacts, 5 is a stationary auxiliary power source mounted on the low floor LRV2 vehicle, and 6 is on the low floor LRV2 vehicle. The air conditioning unit to be installed, 7 is a pantograph mounted on the low-floor LRV2 vehicle, 8 is an overhead hybrid charger integrated inverter mounted on the low-floor LRV2 vehicle, and 9 is a large capacity battery with a heat dissipation device (lithium (Ion battery) 10 is a storage unit.

In particular, copper-based sintered alloy, cast iron, carbon-based conductive material is used as the conductive contact surface material, SiC is used as the friction material, and the conductive material and the friction material are alternately arranged to constitute the contact surface. desirable.

そこで、台車３の台車枠３Ａの側梁の中央部の下部に昇降自在に配置される、広い接触面を有するレール集電用接触子４について図３を参照しながら詳細に説明する。
図３において、台車３の台車枠３Ａはバネ３Ｂを介して車輪３Ｃの車軸３Ｄに連係されるとともに、台車枠３Ａから車輪３Ｃに摺接するように配置される集電ブラシ３Ｅが設けられている。本発明では、さらに、台車３の台車枠３Ａの側梁の中央の下部に、レール集電用接触子４を支持し、上下に駆動を可能にするための、バネ１５やアクチュエータ１４からなる支持装置１１が配置され、その支持装置１１の下部に昇降自在に配置される接触面を有するレール集電用接触子４が設けられるように構成されている。このレール集電用接触子４の材料はカーボンなどの導電部材からなっている。このレール集電用接触子４からのリード線１２が直接大容量バッテリー１０の負極端子に接続されて、低床ＬＲＶ２の停車中に大容量バッテリー１０への充電を行う必要がある場合には、支持装置１１により、レール集電用接触子４を下降させて、大電流（少なくとも１０００Ａ，７５０Ｖ）の急速充電を可能にする。 Therefore, the rail current collector contact 4 having a wide contact surface, which is disposed at the lower part of the central part of the side beam of the carriage frame 3A of the carriage 3 and has a wide contact surface, will be described in detail with reference to FIG.
In FIG. 3, a carriage frame 3A of the carriage 3 is linked to an axle 3D of a wheel 3C via a spring 3B, and a current collecting brush 3E is provided so as to be in sliding contact with the wheel 3C from the carriage frame 3A. . In the present invention, the rail current collecting contact 4 is supported at the lower center of the side beam of the bogie frame 3A of the bogie 3 and is supported by a spring 15 and an actuator 14 for enabling vertical driving. The apparatus 11 is arrange | positioned, and it is comprised so that the rail current collection contact 4 with the contact surface arrange | positioned so that raising / lowering is freely possible in the lower part of the support apparatus 11 is provided. The material for the rail current collector contact 4 is made of a conductive member such as carbon. When the lead wire 12 from the rail current collecting contact 4 is directly connected to the negative terminal of the large capacity battery 10 and the large capacity battery 10 needs to be charged while the low floor LRV 2 is stopped, The support device 11 lowers the rail current collecting contact 4 to enable rapid charging with a large current (at least 1000 A, 750 V).

図４に示すように、例えば、停留所２１にはその屋根２２に短区間の充電用架線２３が配置されており、この充電用架線２３に低床ＬＲＶ２のパンタグラフ７を接触させるとともに、電源１３に接続されたアクチュエータ１４を動作させてレール集電用接触子４を下降させ、レール１に広い面積で接触させ、大電流通電の帰線を確保することにより、大電流の通電による大容量バッテリー１０の充電を短時間で行うことができる。なお、パンタグラフによる給電方式は、種々の方式を用いることができ、図４ではその一例を示しているに過ぎない。   As shown in FIG. 4, for example, a short-section charging overhead line 23 is arranged on the roof 22 of the stop 21, and the pantograph 7 of the low floor LRV 2 is brought into contact with the charging overhead line 23 and the power source 13 is connected. By operating the connected actuator 14 and lowering the rail current collecting contact 4 to bring it into contact with the rail 1 over a wide area and securing the return line of the large current energization, the large capacity battery 10 by the large current energization is obtained. Can be charged in a short time. Note that various methods can be used as the power supply method by the pantograph, and FIG. 4 shows only one example.

なお、アクチュエータ１４は、指令により電源１３からの電力によって得た動力で、レール集電用接触子４をレール面上に押付けたり、上昇指令によって同じく電源１３からの電力によって得た動力で、レール集電用接触子４を上昇させることが可能なものを用いる。一例として、一般的な電磁バネ（プランジャ）方式や電動スクリュー方式を用いることができる。   The actuator 14 uses the power obtained from the power from the power source 13 according to the command, presses the rail current collector contact 4 on the rail surface, or the power obtained from the power from the power source 13 according to the ascending command. What can raise the current collection contact 4 is used. As an example, a general electromagnetic spring (plunger) method or an electric screw method can be used.

次に、レール集電用接触子の駆動方法について詳細に説明する。
図５はそのレール集電用接触子の駆動装置の模式図であり、図５（ａ）はレール集電用接触子のロックが外されようとしている状態を示す駆動装置の模式図、図５（ｂ）はレール集電用接触子がレールに押しつけられる状態を示す駆動装置の模式図、図５（ｃ）はレール集電用接触子がレールから引き上げられる状態を示す駆動装置の模式図である。 Next, a method for driving the rail current collector contact will be described in detail.
FIG. 5 is a schematic diagram of the drive device for the rail current collector contact, and FIG. 5A is a schematic diagram of the drive device showing a state in which the rail current collector contact is about to be unlocked. FIG. 5B is a schematic diagram of the driving device showing a state where the rail current collecting contact is pressed against the rail, and FIG. 5C is a schematic diagram of the driving device showing a state where the rail current collecting contact is pulled up from the rail. is there.

図５において、台車枠３Ａにはレール集電用接触子４を下降又は上昇させるためのアクチュエータ１４と、レール集電用接触子４を押し下げ可能なバネ１５と、レール集電用接触子４をロックするロック機構１６と、アクチュエータ１４とロック機構１６を動作させる駆動回路１７とが設けられている。この駆動回路１７は、レール集電用接触子４の押し付け指令によって動作する第１の接点１８と、レール集電用接触子４の上昇指令（ワンショット）によって動作する第２の接点１９と、ロック機構１６のロック外し指令（ワンショット）によって動作する第３の接点２０を備えている。 In FIG. 5, the carriage frame 3A includes an actuator 14 for lowering or raising the rail current collecting contact 4, a spring 15 capable of pushing down the rail current collecting contact 4, and a rail current collecting contact 4. A lock mechanism 16 for locking, and an actuator 14 and a drive circuit 17 for operating the lock mechanism 16 are provided. The drive circuit 17 includes a first contact 18 that operates according to a pressing command for the rail current collecting contact 4, a second contact 19 that operates according to a lift command (one-shot) for the rail current collecting contact 4, A third contact 20 is provided that operates in response to an unlock command (one-shot) of the lock mechanism 16.

図５（ａ）において、ロック外し指令が与えられると、第３の接点２０が動作して、ロック機構１６は外され、バネ１５のバネ力によってレール集電用接触子４が下降する。
図５（ｂ）に示すように、下降したレール集電用接触子４を、その下降状態からさらにレール面に押し付けるには、押し付け指令により、第１の接点１８を動作させてアクチュエータ１４（電磁プランジャまたは電動スクリューなど）を駆動させる。これにより、レール面にレール集電用接触子４を押し付ける。押し付け指令をワンショット化して、押し付け時間のタイマー設定機構を回路上またはアクチュエータ内部回路に組み込むことも可能である。 In FIG. 5A, when the unlocking command is given, the third contact 20 is operated, the locking mechanism 16 is removed, and the rail current collecting contact 4 is lowered by the spring force of the spring 15.
As shown in FIG. 5 (b), in order to press the lowered rail current collector contact 4 against the rail surface further from the lowered state, the first contact 18 is operated by a pressing command to actuate the actuator 14 (electromagnetic A plunger or an electric screw). This ensures that, pressed against the rail current collector for contact 4 to the rail surface. It is also possible to make the pressing command one-shot and incorporate a timer setting mechanism for the pressing time on the circuit or in the actuator internal circuit.

図５（ｃ）に示すように、レール集電用接触子４が下降した状態から上昇させるには、上昇指令によりアクチュエータ１４を動作させてレール集電用接触子４を上昇させる。レール集電用接触子４がある位置まで上昇すると、バネ１５のバネ力によってロック機構１６のロックが掛かり、時限でアクチュエータ１４の動作は停止する。
次に、このレール集電用接触子による大容量バッテリーの急速大電流充電のフローを図６を参照しながら説明する。 As shown in FIG. 5C, in order to raise the rail current collecting contact 4 from the lowered state, the actuator 14 is operated by the raising command to raise the rail current collecting contact 4. When the rail current collecting contact 4 rises to a certain position, the lock mechanism 16 is locked by the spring force of the spring 15, and the operation of the actuator 14 is stopped in a time limit.
Next, the flow of rapid large-current charging of a large-capacity battery by the rail current collecting contact will be described with reference to FIG.

（１）バッテリーの充電指令が出されたかをチェックする（ステップＳ１）。
（２）ステップＳ１がＹＥＳの場合には、低床ＬＲＶ２は停車したかをチェックする（ステップＳ２）。
（３）ステップＳ２がＹＥＳの場合には、電源１３に接続されたアクチュエータ１４を作動させて、レール集電用接触子４を下降させて広い面積でレール１に接触させ、集電可能にして帰線を形成する。（ステップＳ３）。 (1) It is checked whether a battery charging command has been issued (step S1).
(2) When step S1 is YES, it is checked whether the low floor LRV2 has stopped (step S2).
(3) When step S2 is YES, the actuator 14 connected to the power source 13 is operated to lower the rail current collecting contact 4 to contact the rail 1 over a wide area so that current can be collected. Form a return. (Step S3).

なお、ステップＳ１の充電指令とステップＳ２の停車確認の論理が共に「正」（ＹＥＳ）の場合の具体的動作例は以下の通りである。
まず、ロック解除リレーが動作してバネ力によってレール集電用接触子４が下降する。時素を持たせるか、センサーによる接触検知を行った後、押付け指令リレーが動作することで、アクチュエータには、下向きの力が発生し続け、レール集電用接触子４をレール面に押付ける。 A specific operation example in the case where both the charging command in step S1 and the stop confirmation logic in step S2 are “positive” (YES) is as follows.
First, the unlocking relay operates and the rail current collecting contact 4 is lowered by the spring force. After pressing the element or detecting contact with the sensor, the pressing command relay operates, so that downward force continues to be generated in the actuator, and the rail collecting contact 4 is pressed against the rail surface. .

（４）低床ＬＲＶ２の車上のパンタグラフ７を介して大容量バッテリー１０への充電を開始する。（ステップＳ４）。
（５）充電が完了したら（ステップＳ５）、例えば押付け指令リレーが消磁されて、上昇指令リレーが励磁されることにより、アクチュエータに上向きの力が発生してレール集電用接触子４が上昇を開始する。ある高さまで来ると、バネ力で開いていたロック機構が働いてレール集電用接触子４が落下しないようになる。時素またはロック機構動作の検出により、上昇指令リレーが消磁され、充電前の状態に復帰する。 (4) The charging of the large capacity battery 10 is started via the pantograph 7 on the vehicle of the low floor LRV2. (Step S4).
(5) When charging is completed (step S5), for example, the pressing command relay is demagnetized and the ascending command relay is excited, so that an upward force is generated in the actuator and the rail collecting contact 4 is raised. Start. When a certain height is reached, the locking mechanism that has been opened by the spring force works to prevent the rail current collecting contact 4 from falling. By detecting the time element or the lock mechanism operation, the ascending command relay is demagnetized and returns to the state before charging.

このように構成することにより、大電流の通電により急速に大容量バッテリーへの充電を行うことができる。
次に、車両が傾斜した状態での給電時における車両の横転を防止する機能を有するレール集電用接触子について説明する。
図７は本発明の他の実施例を示す電磁石によりレール集電用接触子にレールへの吸着機能を付加した模式図である。 With this configuration, it is possible to rapidly charge a large-capacity battery by energizing a large current.
Next, a description will be given of a rail current collecting contact having a function of preventing the vehicle from rolling over during power feeding in a state where the vehicle is inclined.
FIG. 7 is a schematic view in which a rail attracting contact function is added to a rail current collecting contact using an electromagnet showing another embodiment of the present invention.

この図において、レール集電用接触子３１には電気的絶縁を施した電磁コイル３２が巻回されて、その電磁コイル３２の電源３３がオンされ、電磁コイル３２が付勢されると、レール集電用接触子３１は磁石となり、レール３４に吸着されることになる。
図８はその吸着機能を付加したレール集電用接触子が適用された状態を示すＬＲＶの模式図である。 In this figure, an electrically insulated electromagnetic coil 32 is wound around the rail current collecting contact 31, the power supply 33 of the electromagnetic coil 32 is turned on, and the electromagnetic coil 32 is energized. The current collecting contact 31 becomes a magnet and is attracted to the rail 34.
FIG. 8 is a schematic diagram of the LRV showing a state in which the rail current collecting contact to which the adsorption function is added is applied.

この図において、４１は低床ＬＲＶであり、この低床ＬＲＶ４１はカント曲線部において停車している。図１に示したように低床ＬＲＶは、低床ＬＲＶの主要機器、つまり、静止型補助電源５、空調ユニット６、パンタグラフ７、架線ハイブリッド充電器一体型インバータ８は極力、車上に配置されるようになっている。したがって、低床ＬＲＶ４１は重心が高くなっており、軌道４２のカント曲線部ではカントにより直線部に比べると、横方向からの外力（例えば、風力）により低床ＬＲＶ４１が横転しやすい状態にある。かかる場合に、その低床ＬＲＶ４１への外力（例えば、風力）に対しても安定性を増加させるために、図７に示した吸着機能を付加したレール集電用接触子３１を用いて、レール４３に吸着させることが得策である。特に、低床ＬＲＶ４１はカント曲線部において停車すると、走行時とは違って低床ＬＲＶ４１に遠心力が作用しないので、横転しやすい状態になる。   In this figure, 41 is a low-floor LRV, and this low-floor LRV 41 stops at a cant curve portion. As shown in FIG. 1, the low floor LRV is the main equipment of the low floor LRV, that is, the stationary auxiliary power supply 5, the air conditioning unit 6, the pantograph 7, and the overhead hybrid charger integrated inverter 8 are arranged on the vehicle as much as possible. It has become so. Therefore, the low floor LRV 41 has a high center of gravity, and the cantilever portion of the track 42 is in a state where the low floor LRV 41 is likely to roll over due to the external force (for example, wind) from the lateral direction. In such a case, in order to increase the stability against the external force (for example, wind power) to the low floor LRV 41, the rail current collecting contact 31 with the adsorption function shown in FIG. It is advisable to adsorb to 43. In particular, when the low floor LRV 41 stops at the cant curve portion, centrifugal force does not act on the low floor LRV 41 unlike during traveling, so that the low floor LRV 41 is likely to roll over.

図９は本発明の他の実施例を示す電磁石によるレール集電用接触子にレールへの吸着機能を付加した場合の動作フローチャートである。
（１）低床ＬＲＶが停車したかをチェックする（ステップＳ１１）。
（２）ステップＳ１１がＹＥＳの場合には、電源１３を動作させて、レール集電用接触子４を下降させて広い面積でレール１に接触させ、集電可能にして帰線を形成する。（ステップＳ１２）。 FIG. 9 is an operation flowchart in a case where a rail attracting function is added to a rail current collecting contact using an electromagnet according to another embodiment of the present invention.
(1 ) It is checked whether the low floor LRV has stopped (step S11).
(2) When step S11 is YES, the power supply 13 is operated, the rail current collecting contact 4 is lowered and brought into contact with the rail 1 over a wide area, and current collection is enabled to form a return line. (Step S12).

（３）次いで、低床ＬＲＶは所定角度以上に傾斜しているかチェックする（ステップＳ１３）。
（４）ステップＳ１３がＹＥＳの場合には、電磁コイル３２を付勢する（ステップＳ１４）。
このように構成することにより、低床ＬＲＶが傾斜した区間で停車している際にも安定な状態を保持することができ、走行の安全性の向上を図ることができる。つまり、低床ＬＲＶの信号停車、故障などによる停車時の電磁吸着によるパーキングブレーキとして活用することができる。 (3) Next, it is checked whether the low floor LRV is inclined at a predetermined angle or more (step S13).
(4) When step S13 is YES, the electromagnetic coil 32 is energized (step S14).
By comprising in this way, a stable state can be hold | maintained even when it has stopped in the area where the low floor LRV inclined, and the improvement of driving | running | working safety | security can be aimed at. That is, it can be utilized as a parking brake by electromagnetic adsorption when the low floor LRV is stopped due to a signal stop or failure.

なお、上記フローでは、低床ＬＲＶが傾斜した区間で給電を行うことについては触れていないが、当然、低床ＬＲＶの車上のパンタグラフを介して大容量バッテリーへの充電を開始することができることは言うまでもない。
このように構成することにより、低床ＬＲＶが停車し傾斜した区間で、レールへの吸着機能を持たせることにより、低床ＬＲＶを安定状態に保持することができるとともに、大電流の通電により急速に大容量バッテリーへの充電を行うことができる。 The above flow does not mention that power is supplied in a section where the low floor LRV is inclined, but naturally, charging of a large capacity battery can be started via a pantograph on the vehicle of the low floor LRV. Needless to say.
With this configuration, the low floor LRV can be held in a stable state by providing a function of adsorbing to the rail in a section where the low floor LRV is stopped and inclined, and is rapidly activated by energization with a large current. It is possible to charge a large capacity battery.

また、集電用接触子は、大電流の急速充電のみならず、低床ＬＲＶの高速走行からの緊急レールブレーキとしても動作させることも可能である。
