Description

【0001】
【産業上の利用分野】
本発明は電気車両に用いられる直動式パンタグラフ装置の摺動兼回転防止構造に関する。
【0002】
【従来の技術】
電気車両のパンタグラフ装置は架線から車両へ電力を導入する車両部品であるが、線路に沿って高さや偏位の変化する架線の位置範囲に十分追随できる大きさが必要であり、車両が必要とする電力に応じて十分な電流を流せる構造であること、車両が高速で走行するに従って離線が発生し易くなるが、十分な追随性能を有すること、オーバラップや区分セクション等で加わる衝撃的な力や、走行に伴う空気抵抗や揚力に対して十分な強度を有することなどが必要とされる。
【0003】
従来のパンタグラフ装置としては菱形枠組構造をなすものが知られているが、枠体にかかる風圧が大きく、風切り音も大きくなり、しかも重量が重く、構造が複雑になるためにメンテナンスも大変である。そこで、最近ではエアシリンダを互いに摺動するアウタパイプとインナパイプ内に収めた直動式のパンタグラフ装置が提案されている。
【0004】
しかし、上述した直動式のパンタグラフ装置にあっては、リフトシリンダが2本の場合は問題はないが、1本の場合には、インナパイプがアウタパイプに対して回転してしまうため、摺動兼回転防止構造を必要とする。
【0005】
図5はこのような従来の直動式パンタグラフ装置の摺動兼回転防止構造を説明するためのものであって、パンタグラフ装置のガイドローラ部分の横断面図である。
【0006】
上記した従来の直動式パンタグラフ装置100は、例えばアウタパイプ101の上部の四隅に開口窓102を形成し、またカバー103及びアウタパイプ101にガイドローラブラケット104を固着し、このガイドローラブラケット104の両端部に支軸105で回転可能に軸支したガイドローラ106を前記開口窓102に臨ませ、インナパイプ107の四隅の辺108の外面に前記ガイドローラ106を当接させるようにしたものがある。尚、109はエアシリンダを示す。
【0007】
【発明が解決しようとする課題】
しかし、上述した直動式パンタグラフ装置の摺動兼回転防止構造にあっては、ローラの当接面がインナパイプに直角に取り付けられてはいてもそのローラの全ての軸はローラとインナパイプの当接面と略平行に設けられ、しかもローラと軸との間には軸方向の隙間があるので、インナパイプにはローラの軸方向の隙間に起因する倒れ、更にインナパイプの中心軸廻りの回転が生じてしまう。
【0008】
【課題を解決するための手段】
上記課題を解決すべく本願の請求項1に係る直動式パンタグラフ装置の摺動兼回転防止構造は、エアシリンダの外側にアウタパイプと、このアウタパイプに対して相対的に上下動するインナパイプを隙間を介して配置したリフトシリンダ装置にて集電舟体を垂直方向に昇降動せしめるようにした直動式パンタグラフ装置の摺動兼回転防止構造において、インナパイプはその中心から径方向に延びる軸線に直交する第1の摺動面と、軸線に平行な一対の第2摺動面を有し、アウタパイプは第1摺動面に当接する第1ローラー及び一対の第2摺動面を挟み込む第2ローラーを取り付け、アウタパイプの上部にインナローラのガイドローラを設けた。ここで、前記第1の摺動面及び第2の摺動面は、それぞれ対向する位置に一対設けるのが好ましい。
【0009】
【作用】
本願の請求項1に係る直動式パンタグラフ装置の摺動兼回転防止構造は、エアシリンダの伸縮に応じてアウタパイプとインナパイプとが相対的に上下動する。この時、第1の摺動面は第1のローラの径方向を規制するよう当接し、この第1の摺動面と直交する第2の摺動面はそれぞれ一対の第2のローラとインナパイプの回転方向を規制するように当接する。
更に、前記第1の摺動面及び第2の摺動面は、それぞれ対向する位置で第1のローラおよび第2のローラと当接する。
【0010】
【実施例】
以下に本発明の実施例を添付図面に基づいて説明する。ここで、図1は本発明に係る直動式パンタグラフ装置の摺動兼回転防止構造を適用した直動式パンタグラフ装置の一部を破断して示した正面図、図2は同直動式パンタグラフ装置の平面図、図3は同直動式パンタグラフ装置の要部拡大断面図である。
【0011】
図中1は車両の屋根の上に碍子を介して固定される台枠であり、この台枠1上に軸2を中心としてベース3を回動自在に枢着し、このベース3にはレバー4を取り付け、このレバー4と台枠1との間に収納用エアシリンダ5及び油圧ダンパ6を設け、エアシリンダ5を伸長することで、ベース3に取り付けた直動式パンタグラフ装置10を図1の実線で示した起立状態から想像線で示した収納状態とするようにしている。尚、油圧ダンパ6は直動式パンタグラフ装置10が勢よく倒れないようにするためのものである。
【0012】
直動式パンタグラフ装置10はベース3にリフトシリンダ装置11のアウタパイプ12の基部をブラケット等を介して固定し、このアウタパイプ12内にインナパイプ13を摺動自在に挿通し、アウタパイプ12上部にインナパイプ13の廻り止めを兼ねるガイドローラ装置14…を設けている。
【0013】
前記インナパイプ13の上端には取り付け部材15を上方から嵌合している。この取り付け部材15は上端部が外方に広がるフランジ部15aとなっており、このフランジ部15aに導電性のバー16の上端を取り付け、このバー16に給電用のシャントリード線(図示せず)を接続している。
【0014】
また、前記インナパイプ13内の上部で取り付け部材15の内側にはキャップ状受け部材18を取り付け、更にリフトシリンダ装置11内にはエアシリンダ19を配置し、このエアシリンダ19のロッド19aの上端を前記キャップ状受け部材18の上端内側に連結し、エアシリンダ19の駆動によりインナパイプ13が伸縮動し、インナパイプ13の伸長動によって集電舟体20が架線に下方から接触し、圧縮動によって架線から離れる。
【0015】
また、前記ベース3にはリフトシリンダ装置11のアウタパイプ12を囲むようにカバー21が立設し、前記フランジ部15aにはブラケットを介して前記カバー21と一部が重なるようにフェアリング22の上端部が固着されている。
【0016】
一方、前記集電舟体20は高周波振動吸収装置30を介してリフトシリンダ装置11に支持されている。即ち、高周波振動吸収装置30は、取り付け部材15とキャップ状受け部材18との間には形成された隙間にリニアボールベアリング31を介してスライダ32を摺動自在に配置し、このスライダ32上端に集電舟体20を取り付け、キャップ状受け部材18の上端部とスライダ32上端部内側との間にスプリング33を設け、架線に追従して集電舟体20が滑走する際の高周波振動をスライダ32が振動することで吸収している。
【0017】
尚、スライダ32と前記取り付け部材15のフランジ部15aとの間には二股状のアーム34を設け、スライダ32の廻り止めを行うようにしている。
【0018】
また、スライダ32にはその下端部が前記フェアリング22とオーバラップするようアッパーキャップ35を固着している。
【0019】
次に、上記構成の直動式パンタグラフ装置に適用されている直動式パンタグラフ装置の摺動兼回転防止機構を説明する。
図4は図3の4−4矢視断面図であり、図3と同一部分には同一符号を付して説明を省略する。
【0020】
アウタパイプ12は断面四角形状に形成され、またインナパイプ13は断面多角形状に形成されている。インナパイプ13はその中心Oを通って径方向に延びる軸線Lに直交する第1の摺動面40と、この軸線Lに平行な、前記第1の摺動面40の両端から直角に連なる一対の第2の摺動面41,41を有し、アウタパイプ12の内周側に紙面上方からインナパイプ13を隙間sを介して嵌装する。
【0021】
アウタパイプ12の対向する面42の中央部には開口窓43を形成し、またこのアウタパイプ12の対向する面42には一対のガイドローラブラケット44,45を固着し、これら一対のガイドローラブラケット44,45の各端部に前記対向する面42と平行に延びる支軸46をボルト47で固定し、この支軸46で回転可能に軸支された第1のガイドローラ50を前記開口窓43に臨ませている。そして、前記インナパイプ13の第1の摺動面40に前記第1のガイドローラ50を当接させている。なお、一対のガイドローラブラケット44,45は、一体に形成すれば精度の高いものを得ることができ、より好ましい。
【0022】
更に、前記それぞれのガイドローラブラケット44,45には対向する面42を垂直に貫通して内方に延びる支軸48,49をボルト51,52で取り付け、その支軸48,49の先端部にそれぞれ第2のガイドローラ53,54を回転可能に軸支している。そして、これら一対の第2のガイドローラ53,54をインナパイプ13の第2の摺動面41、41にそれぞれ当接させて、第2のガイドローラ53,54で第2の摺動面41、41間を挟み込むようにしている。
【0023】
摺動兼回転防止機構は、以上のように構成したため、外部エア供給源からリフトシリンダ装置11のエアシリンダ19にエアを供給することによって、インナパイプ13を上昇・下降させて集電舟体20(スライダ32)を上昇・下降させたとき、インナパイプ13の第1の摺動面40に当接する第1のガイドローラ50によって径方向(軸線方向L)への倒れが阻止され、インナパイプ13の第2の摺動面41に当接する第2のガイドローラ53,54によってローラ50の軸方向の隙間に起因するインナパイプ13の中心O廻りの回転が阻止される。
【0024】
【発明の効果】
以上に説明したように本発明に係る直動式パンタグラフ装置の摺動兼回転防止構造によれば、リフトシリンダ装置にて集電舟体を垂直方向に昇降動せしめるようにした直動式パンタグラフ装置において、前記リフトシリンダ装置はエアシリンダの外側にアウタパイプとこのアウタパイプに対して相対的に上下動するインナパイプを隙間を介して配置し、インナパイプはその中心から径方向に延びる軸線に直交する第1の摺動面と、軸線に平行な第2の摺動面とを有し、またアウタパイプはその内周に前記第1の摺動面及び第2の摺動面とそれぞれ当接する第1のローラ及び第2のローラを取付けたので、エアシリンダの伸縮に応じてアウタパイプとインナパイプとが相対的に上下動した時、第1の摺動面と当接する第1のローラで径方向の倒れを防止し、第2の摺動面にそれぞれ当接する一対の第2のローラでインナパイプの中心廻りの回転を防止するため、直動式パンタグラフ装置はアウタパイプに対するインナパイプの倒れや回転を阻止でき、ガタのないスムーズな上下動が可能となる。この際、第1の摺動面及び第2の摺動面をそれぞれ対向する位置に一対設けるようにすれば、上記効果をより顕著に発揮することができる。
