Abstract
Description
特許文献1記載および特許文献2記載の軌道分岐部の異物除去装置のいずれも、落下雪氷や飛石に対する有用性は非常に高い。
特許文献2に記載の異物除去装置のノズル部は、特許文献2の図4に示すように、多数の小径噴射口および3個の大径噴射口を有する。この多数の小径噴射口から圧縮空気が噴出される際に発生する騒音のため、近隣に民家などが近い場合に設置し難いという問題があった。その結果、設置が要望される地域または場所が多数あるにもかかわらず、これらの場所に設置が進んでいなかった。
一局面に従う軌道分岐部の異物除去装置は、軌道分岐部の基本レールとトングレールとの間に落下した異物を除去する軌道分岐部の異物除去装置であって、圧縮空気を供給するために設けられた配管部と、配管部から供給される圧縮空気を噴射する噴射ノズル部と、を含み、噴射ノズル部は、トングレールに対向する側に設けられ、かつノズル先端に行くに従い基本レール側に近づく傾斜部を有する柱状筐体と、圧縮空気を噴射するために柱状筐体の内部をその中心軸方向に貫通して設けられ、少なくともその一部が傾斜部に開口し、かつ基本レールに対向する側には開口していないスリットと、を備え、噴射ノズル部の中心軸は基本レールに沿う方向からトングレール側に所定の角度をもって配設されたものである。
更にノズルを円錐状とし、圧縮空気の噴射口を円錐側面に開口するスリット形状とすることで、圧縮空気の噴射口を単純な丸穴にする場合に比べ、騒音を大幅に低減できながら、噴射圧力は十分に確保できることを実験的に確認した。しかし、この知見をそのまま軌道分岐部の異物除去装置に適用すると、噴射された圧縮空気は基本レールに衝突し、それに伴い騒音が発生することになってしまう。
一方、当該スリットは基本レールに対抗する側には開口していないため、円錐側面に開口したスリットと同様の効果は奏さないものの、噴射された圧縮空気が基本レールに衝突するのが防止されるので、当該衝突に伴う騒音の発生が抑えられる。
ここで、傾斜部は、平面であっても曲面であってもよく、スリットはその断面形状が、矩形であっても楕円であっても三角形を含む多角形であってもよい。
軌道分岐部の異物除去装置において、傾斜部は、円柱筐体の天面側から側周面に向かう平面により形成されてもよい。
軌道分岐部の異物除去装置において、配管部は、基本レールのトングレール側の側面に設けられた角パイプ状の配管であり、配管部の上側または下側の何れか一方または両方に設けられるとともに、傾斜部の平面は上面または底面の投影面積内に設けられるように配設されてもよい。
軌道分岐部の異物除去装置において、スリットは、柱状筐体の軸芯周りに放射状に複数配設されてもよい。
軌道分岐部の異物除去装置において、噴射ノズル部は、同じ形状のものが複数個設けられ、一の噴射ノズル部の噴射方向と、他の噴射ノズル部の噴射方向とが異なってもよい。
他の局面に従う軌道分岐部の異物除去装置は、レールの軌道分岐部に対して設けられ、圧縮空気を噴射することでレールとレールとの間に落下した異物を除去する軌道分岐部の異物除去装置であって、レールが交差するクロッシング部の前方側に配置された錐台状の噴射筐体部と、クロッシング部の後方側に向かって圧縮空気を噴射可能に設けられ、かつ噴射筐体部の側面に形成された1または複数のスリットと、噴射筐体部の圧縮空気導入口から内部を通過して1または複数のスリットに圧縮空気を導くガイド部と、を含むものである。
更にノズルを円錐状とし、圧縮空気の噴射口を円錐側面に開口するスリット形状とすることで、圧縮空気の噴射口を単純な丸穴にする場合に比べ、騒音を大幅に低減できながら、噴射圧力は十分に確保できることを実験的に確認した。そして、この知見をもとに、更に改良を加え、噴射筐体部の内部にガイド部を設けることとした。すなわち、ガイド部に沿って圧縮空気を流すことができるため、圧縮空気が噴射筐体部の内部壁に急激に衝突することを緩和し、スリットから噴射される気体の流れが乱れることを抑制できる。その結果、圧縮空気噴射時の圧力を維持しつつ、噴射された圧縮空気により発生する騒音を大幅に低下させることができる。
なお、スリットの断面形状としては、矩形のほか、楕円や三角形を含む多角形であってもよい。
軌道分岐部の異物除去装置において、ガイド部は、円錐形状からなってもよい。
他の局面に従う軌道分岐部の異物除去装置に用いられるノズルは、軌道分岐部の基本レールとトングレールとの間に落下した異物を除去する軌道分岐部の異物除去装置に用いられるノズルであって、圧縮空気を供給するために設けられた配管部と、配管部から供給される圧縮空気を噴射する噴射ノズル部と、を含み、噴射ノズル部は、トングレールに対向する側に設けられ、かつノズル先端に行くに従い基本レール側に近づく傾斜部を有する柱状筐体と、圧縮空気を噴射するために柱状筐体の内部をその中心軸方向に貫通して設けられ、少なくともその一部が傾斜部に開口し、かつ基本レールに対向する側には開口していないスリットと、を備え、噴射ノズル部の中心軸は基本レールに沿う方向からトングレール側に所定の角度をもって配設されたものである。
更にノズルを円錐状とし、圧縮空気の噴射口を円錐側面に開口するスリット形状とすることで、圧縮空気の噴射口を単純な丸穴にする場合に比べ、騒音を大幅に低減できながら、噴射圧力は十分に確保できることを実験的に確認した。しかし、この知見をそのまま軌道分岐部の異物除去装置に用いられるノズルに適用すると、噴射された圧縮空気は基本レールに衝突し、それに伴い騒音が発生することになってしまう。
一方、当該スリットは基本レールに対抗する側には開口していないため、円錐側面に開口したスリットと同様の効果は奏さないものの、噴射された圧縮空気が基本レールに衝突するのが防止されるので、当該衝突に伴う騒音の発生が抑えられる。
ここで、傾斜部は、平面であっても曲面であってもよく、スリットはその断面形状が、矩形であっても楕円であっても三角形を含む多角形であってもよい。
(軌道分岐部の構成)
クロッシング部Cは、軌道分岐部500の後方側において翼レール504、可動レール505、および固定部506が配置された領域として構成される。
本実施形態では、ポイント部Pおよびリード部Lが、軌道分岐部500において前方側に位置する前方部を構成し、クロッシング部Cは、この前方部とは反対側の後方側に位置してレールが交差する部分を含む領域として構成している。
次に、第1実施形態に係る異物除去装置用ノズル100を備えた異物除去装置300の構成について説明する。
異物除去装置用ノズル100は、上述した軌道分岐部500の基本レール501とトングレール502との間に設けられる。本実施の形態に係る異物除去装置用ノズル100を備えた異物除去装置300は、該異物除去装置用ノズル100から圧縮空気を噴射することで基本レール501とトングレール502との間に落下した雪または飛石等の異物を除去する。
次に、図2は異物除去装置用ノズル100を側面から視野した場合の一例を示す模式図であり、図3は異物除去装置用ノズル100を上方から視野した場合の模式図であり、図4は、基本レール501に取り付けられた異物除去装置用ノズル100を示す模式的断面図である。
図5はノズル110の詳細を示す正面図であり、図6はノズル110の側面図であり、図7はノズル110の製造方法を説明するための模式図である。
図6に示すように、ノズル110は、円筒状体161が配管180の延在方向とほぼ同じ方向となるよう、保持部162により保持され、L字状を形成する。なお、保持部162の内部は、配管180から圧縮空気PAが供給されるように中空となっている。
また、図5および図6に示すように、複数のスリット140は、円筒状体161の内部をその中心軸方向に保持部162の内部空間まで貫通して設けられ、かつ複数のスリット140は、円筒状体161の天面120に天面120の仮想円の中心から放射状となるよう、複数のスリット140が配設される。なお、基本レール501側には傾斜部130は設けられないため、基本レール501側に設けられるスリット140は、天面120に開口している。すなわち、スリット140は、基本レール501側には、開口していない。本実施の形態において、複数のスリット140は、矩形状からなる。
図8に示すように、スリット140の断面形状は、楕円形からなるスリット140aでもよく、図9に示すように、台形状からなるスリット140bでもよい。更には、三角形その他の多角形からなるスリットでもよい。
また、図10に示すように、複数のスリット140の配置は、千鳥配置または格子状に配置した複数のスリット140cでもよい。
さらに、図12の異物除去装置用ノズル100eに示すように、ノズル110eは、配管180の側面に設けてもよい。この場合、ノズル110eから噴射される圧縮空気が配管180に衝突するのが防止される結果、当該衝突に伴う騒音の発生が抑えられる。
具体的には、傾斜部が設けられておらず、噴射口も単なる丸孔から構成される場合と比較して、騒音値を半減させることができる。なお、圧縮空気の出力は10%から20%程度の低下であるため、実用上は問題なく、異物除去性能に影響はほとんど無い。
(軌道分岐部の構成)
クロッシング部Cは、軌道分岐部500の後方側において翼レール504、可動レール505、および固定部506が配置された領域として構成される。
本実施形態では、ポイント部Pおよびリード部Lが、軌道分岐部500において前方側に位置する前方部を構成し、クロッシング部Cは、この前方部とは反対側の後方側に位置してレールが交差する部分を含む領域として構成している。
また、クロッシング部Cの可動レール505は、転轍機(図示せず)の作動に伴いトングレール502と連動して変位するように構成され、固定部を支点構造として揺動するように変位し、その前方側の端部が翼レール504に対して当接または離間するように構成されている。
次に、第2の実施形態に係る異物除去装置300用のノズル部110を備えた異物除去装置300の構成について説明する。異物除去装置300は、上述した軌道分岐部500のクロッシング部Cの翼レール504に設けられる。
本実施の形態に係る異物除去装置用のノズル部110を備えた異物除去装置300は、該ノズル部110から圧縮空気PAを噴射したり、温風HAを送風したりすることで翼レール504、または翼レール504および可動レール505に落下した雪または飛石等の異物を軌道分岐部500の後方側に向かって吹き飛ばして除去したり、雪を融解させたりしている。温風HAの送風については、本発明とは関係ないため、以後、説明を省略する。
次に、図14は異物除去装置300を翼レール504とともに後方側から前方側に向けて視野した場合の一例を示す模式的断面図であり、図15はノズル部110を上方から視野した場合の模式図である。図14に示すように、ノズル部110は、翼レール504の間に設けられている。
次いで、図16は異物除去装置300のノズル部110の一例を示す模式的斜視図であり、図17は異物除去装置300のノズル部110の一例を示す模式的平面図であり、図18は異物除去装置300のノズル部110の一例を示す模式的側面図であり、図19は異物除去装置300のノズル部110の一例を示す模式的上面図である。
図20は、ノズル200の構造の一例を示す模式的断面図である。図20(a)はノズル200の断面を示し、図20(b)はノズル200の裏面から視野した状態を示す。
その結果、ガイド210により圧縮空気PAは、流れPAFの方向に向かって円滑に流れ、複数のスリット230から噴射することができる。したがって、圧縮空気PAの流れPAFを乱すことなく、円滑に圧縮空気PAを流すことができるので、ノズル200から発生する騒音を大幅に低下させることができる。また、後述するノズル構造の他の例と比べ、ガイド210を円錐形状とすることとで、全てのスリット230に対し、圧縮空気PAを流れPAFの方向に向かって円滑に流すことができるので、最も騒音を低下することができる。
図21に示すノズル部110aのように、導入口141側へ向かって形成された2つの平面から構成された斜面のガイド210aを有するノズル200aとしてもよい。
また、ノズル部110にノズル200を1個設けることとしたが、これに限定されず、他の任意の個数設けてもよい。
