Description

【０００１】
【発明の属する技術分野】
本発明は鉄道車両用渡り板装置に関する。
【０００２】
【従来の技術】
鉄道車両の連結部には、連結された車両間を人が移動するための渡り板が設けられているとともに、この渡り板からなる連結通路の外周が、連結車両間に設けた幌で被覆されている。
【０００３】
車両の連結部は、連結車両相互が水平方向に偏倚したり、上下方向に振動するため、連結された一方の車両に一方の渡り板を上下方向に回転可能に備え、他方の車両に他方の渡り板を上下方向に回転可能に備え、これら両渡り板の先部を水平位置で重ね合わせて連結通路の床板を構成している。
【０００４】
このような渡り板を車両に取り付ける構造として、従来、図１６及び図１７に示すように、渡り板１０１，１０２の基部と車両１０３，１０４の一方にピン１０５を固定し、他方に前記ピン１０５の全周を囲む取付穴１０６を設けて、これらを回転可能に嵌合したヒンジ構造とし、渡り板１０１，１０２を単に起伏可能に車両へ取り付けるものが一般的である。
【０００５】
また、連結通路方向の中間部で幌を分割し、その分割部における開放側幌金枠と車両とに渡り板を前記と同様の構造により取り付けるものもあり、例えば特開昭６１−１０５２６９号や特開平７−３０９２３３号公報に開示されている。
【０００６】
【発明を解決しようとする課題】
ところで、車両連結部に張設された幌における底壁と渡り板との間、すなわち渡り板の下部空間にはごみが入ったり、機器が配置されているため、この下部空間において清掃や点検保守などの作業が行われる。
【０００７】
このような清掃や点検保守などの作業を行う場合、渡り板が前記従来のようなヒンジ構造で取り付けられているものにおいては、その渡り板１０１，１０２を図１７の鎖線で示すようにヒンジ部で旋回起立し、この起立した状態で清掃や点検保守を行う必要がある。
【０００８】
このように渡り板を起立させた状態では、該連結通路部での作業者の通行が困難になる上に前記の清掃、点検保守も困難になり、車両全体の点検作業に支障をきたす問題がある。更に、連結車両の分割、併合作業にも渡り板が邪魔になって支障をきたす問題がある。
【０００９】
そこで本発明は、前記のような点検保守作業時や連結車両の分割、併合作業には、渡り板を取り外すことができるようにして前記の問題を解決することを目的とするものである
【００１０】
【課題を解決するための手段】
前記の課題を解決するために、請求項１記載の発明は、渡り板を連結通路の幅方向に複数に分割し、その分割された一部の分割渡り板を取り付ける部材に横軸と、該横軸の前側に位置して所定の隙間を有して外れ防止手段を夫々固設し、前記一部の分割渡り板の基部側の下面に、後方が開口するＵ状の渡り板軸受を固設し、該渡り板軸受を前記横軸に回転可能に嵌合して該横軸を中心として前記一部の分割渡り板を上下方向に旋回可能に備え、その一部の分割渡り板が略水平姿勢の状態では前記渡り板軸受が前記横軸と外れ防止手段に係止してその渡り板の外れが阻止され、その渡り板を上方へ所定量旋回した状態で上方へ持ち上げることにより渡り板軸受が横軸から外れるようにし、また、前記一部の分割渡り板に隣接する他の分割渡り板の基部と該他の分割渡り板を取り付ける部材には、その一方に横軸を設け、他方に軸穴を設け、これらを回転可能に嵌合するとともに該他の分割渡り板を前記一部の分割渡り板側へ移動することにより前記横軸と軸穴との嵌合が外れるようにしたことを特徴とするものである。
【００１５】
本発明においては、複数の分割された各分割渡り板が使用状態の略水平姿勢では、その各分割渡り板が車両或いは幌枠などの取付部材から外れることなく、横軸を中心として車両の上下振動に対し必要量分若干上下に旋回して追従する。
【００１６】
また、渡り板を取り外す場合には、先ず、渡り板軸受を有する一部の分割渡り板を略水平の取付状態から所定量上方へ旋回させて渡り板軸受の開口部を下向きにし、その後、その渡り板を上方へ持ち上げることにより、渡り板軸受が横軸から外れ、その渡り板を、その取付部材から取り外すことができる。その後、隣接する分割渡り板を前記一部の分割渡り板が存在していた方向へ移動させて取り外す。
【００１７】
また、前記のように取り外した各渡り板を取付部材に取り付ける場合には、前記の取り外し工程とは逆の工程により取り付けることができる。
【００１８】
【発明の実施の形態】
図に示す実施例に基づいて本発明の実施の形態について説明する。
【００１９】
図１乃至図７は本発明を説明するための実施例を示すものでこれを第１実施例とする。
【００２０】
図１は幌の側部の下方を切開した車両連結部の略側断面図、図２はその略平断面図で、この図において、連結した一方の車両１の妻面１ａと、他方の車両２の妻面２ａとの間に、幌枠３，４を介して１枚の幌５が張設されている。該幌５は周知のように連結通路６部の外周を囲むように筒状に形成されている。
【００２１】
一方の車両１の妻面１ａには一方の取付手段７により一方の渡り板８が他方の車両２側へ突出するように備えられ、また、他方の車両２の妻面２ａには他方の取付手段９により他方の渡り板１０が一方の車両１側へ突出するように備えられている。また、前記一方の渡り板８は一方の車両１の床面１ｂと略同一位置において水平方向に配置され、他方の渡り板１０は他方の車両２の床面２ｂと略同一位置において水平方向に配置されるようになっている。更に、一方の渡り板８における突出側の先部８ａの上面に他方の渡り板１０における突出側の先部１０ａが重合状に載置するようになっている。更に、前記両渡り板８，１０の下側に幌５の底壁５ａが配置されている。
【００２２】
以上の構成により、幌５内において、両渡り板８，１０を水平方向に配置するとともに夫々の先部を重合して、この渡り板８，１０により連結車両間の連結通路６の床板を構成している。
【００２３】
次に、前記一方の渡り板８の取付手段７について図２乃至図５により詳述する。なお、この取付手段７は、一方の渡り板８における幅方向の両側に設けられているが、夫々同一構造であるため、片側の取付手段について説明する。
【００２４】
図２及び図３において、一方の渡り板８における車幅方向の両端部８ｂ，８ｂの近傍に位置して車体側軸受１１が配置され、該車体側軸受１１が渡り板の取付部材である一方の車体１の妻面１ａに固定されている。該車体側軸受１１には、一方の渡り板８に向って水平に突出する、すなわち、車幅方向に水平に突出する横軸１２が固設されている。該横軸１２は所定の長さに設定されており、図３に示すように一方の渡り板８の側部付近に位置するように短尺に設定してもよく、また、一方の渡り板８の横幅方向の全長にわたる長さに設定してもよい。
【００２５】
前記一方の渡り板８の基部側、すなわち、連結通路方向における一方の車両１側の端部には、その下面において図５に示すように取付座１３が固設されている。該取付座１３の下面には渡り板軸受１４が固設されている。
【００２６】
該渡り板軸受１４は、図５に示すように、渡り板８を略水平に配置した場合に、その渡り板８の後方側、すなわち、一方の車両１に対向する側が開口するＵ字状の横断面形状に形成されている。換言すると、渡り板８を略垂直状態に起立した場合に、渡り板軸受１４が、下方を開口した逆Ｕ字状の形態になるように形成されている。該渡り板軸受１４のより具体的な横断面形状は半円部１４ａとその両端から直線状に延びた直線部１４ｂと、開口部１４ｃとからなり、半円部１４ａと両直線部１４ｂは同一板厚に形成されている。
【００２７】
更に、該渡り板軸受１４における半円部１４ａの内曲面１４ｄの内径と両直線部１４ｂ間の寸法は、前記横軸１２の円断面の外径と略同等に設定され、渡り板軸受１４が横軸１２に同心状に嵌合し、かつ相互間のガタツキを少なくして回転可能に嵌合するようになっている。
【００２８】
また、該渡り板軸受１４は、一方の渡り板８の横幅全長にわたる長さに形成されているが、前記横軸１２を図３に示すように短尺に形成した場合には、該横軸１２と同一位置において略同長の短尺に形成してもよい。
【００２９】
前記一方の車両１の妻面１ａには図５に示すように、前記一方の渡り板８の下部に位置して軸受案内板１５が固設されている。該軸受案内板１５は車両への取付板１５ａと、前記横軸１２の前側、すなわち横軸１２に対して車両１側と反対の側において起立した案内板１５ｂと、該案内板１５ｂの上端において略水平に折曲した支承板１５ｃとからなる。該軸受案内板１５は、一方の渡り板８の横幅方向の略全長、すなわち、前記渡り板軸受１４の略全長にわたって設けられているが、渡り板軸受１４の軸方向の一部に設けてもよい。
【００３０】
前記案内板１５の車両側面には樹脂材料などからなるスリ板１６が固着されている。該スリ板１６は、前記横軸１２と同一高さの位置、すなわち、前記渡り板軸受１４が嵌合される位置において設けられている。更に、該スリ板１６の内面１６ａの位置は、該面１６ａと前記横軸１２の外周面との間の隙間ｄが前記渡り板軸受１４の板厚よりも若干大きい寸法になるように設定されている。すなわち、スリ板１６の内面１６ａが渡り板軸受１４の外面１４ｅに若干の隙間をもって近接している。なお、前記軸受案内板１５とスリ板１６により、前記一方の渡り板８の外れを防止する外れ防止手段１７を構成している。
【００３１】
前記支承板１５ｃにはボルト状の受金１８が垂直方向に螺合して備えられ、該受金１８を正逆回転することにより、その上面の支承面１８ａの高さを調節できるようになっている。また、その調節位置は、固定ナット１９で固定するようになっている。そして、図５に示すように一方の渡り板８の渡り板軸受１４を横軸１２に嵌合してその一方の渡り板８を倒伏した場合に、その一方の渡り板８が前記受金１８により支持されて、その一方の渡り板８の略水平状態からの旋回下降が阻止され、また、受金８を回転してその高さを調節することにより、一方の渡り板８の水平面との角度（水平度）を調節できるようになっている。なお、前記支承板１５ｃと受金１８により渡り板の下降阻止手段２０を構成している。この下降阻止手段２０は、前記の構成に限らず、前記支承板１５ｃにより直接渡り板８を支持するようにしてもよく、更に他の構造で渡り板８を支持するようにしてもよい。
【００３２】
前記図１及び図２に示した他方の渡り板１０の取付手段９は、前記一方の渡り板８の取付手段７と同様の構造である。すなわち、前記と同様の車体側軸受１１、横軸１２、取付座１３、渡り板軸受１４、軸受案内板１５、スリ板１６で構成されている。したがって、この他方の渡り板１０の取付手段９の構造の説明は省略する。
【００３３】
なお、他方の渡り板１０側には、前記の支承板１５ｃ、受金１８（下降阻止手段２０）は設けられていない。また、他方の渡り板１０の先部の下面には図１及び図２に示すようにスリ板２１が固着されており、該スリ板２１を介して他方の渡り板１０の先部が前記一方の渡り板８の先部の上面に載置されている。
【００３４】
以上の構造において、図５に示すように、一方の渡り板８の渡り板軸受１４を横軸１２に嵌合するとともにその一方の渡り板８の下面を下降阻止手段２０である受金１８上に載置して一方の渡り板８を略水平の倒伏状態に取り付け、また、他方の渡り板１０も、前記一方の渡り板８と同様に取り付けるとともにその先部を一方の渡り板８に載置した状態での作用を説明する。
【００３５】
この状態では、一方の渡り板８の渡り板軸受１４が横軸１２に回転可能に嵌合されているため、車両１，２の走行時に上下振動があった場合、この振動に対し一方の渡り板８が横軸１２を中心として上下方向に円滑に追従旋回できる。また、他方の渡り板１０も同様に上下方向に追従旋回できる。
【００３６】
また、渡り板軸受１４に開口部１４ｃが形成されているが、外れ防止手段１７であるスリ板１６の内面１６ａが渡り板軸受１４の外面１４ｅに近接していることにより、一方の渡り板８の略水平姿勢或いは水平状態から若干上方へ旋回した姿勢においては、渡り板軸受１４の半円部１４ａが横軸１２とスリ板１６間に挟まれ、かつ渡り板軸受１４の下側直線部１４ｂが横軸１２に係止して、一方の渡り板８は外れない。
【００３７】
他方の渡り板１０も前記一方の渡り板８と同様に旋回可能で、かつ外れない。
【００３８】
また、一方の渡り板８は下降阻止手段２０によって下方への旋回が阻止され、設定された略水平姿勢が保持される。
【００３９】
また、他方の渡り板１０には前記の下降阻止手段２０が設けられていないが、その他方の渡り板１０の先部が前記一方の渡り板８の先部上面に重ねられるため、その他方の渡り板１０が略水平状態から下方へ旋回下降することも阻止される。
【００４０】
また、連結車両１，２間において偏倚や伸縮が生じた場合には、一方の渡り板８と他方の渡り板１０は、その前記重合部が摺動して追従移動する。
【００４１】
次に、両渡り板８，１０の前記の略水平な設置状態から、連結部の清掃や点検保守を行うために、両渡り板８，１０を取り外す場合について説明する。
【００４２】
この場合には、一方の渡り板８を、その先端を持って、図６に示すように、横軸１２と渡り板軸受１４の嵌合部を中心として上方へ旋回させて略垂直に起立させる。これにより渡り板軸受１４も同様に回転してその開口部１４ｃが下向きになるとともに直線部１４ｂがスリ板１６の内面１６ａと略平行する。したがって、この起立状態からその一方の渡り板８を上方へ持ち上げることにより、その一方の渡り板８を図７に示すように車両１から取り外すことができる。
【００４３】
また、他方の渡り板１０も前記と同様にして取り外す。
【００４４】
このように両渡り板８，１０を取り外すことにより、前記従来のように単に渡り板を起立させるものと比較して幌内における底部での清掃や点検保守の作業が容易に行えるとともに作業者が連結通路部を通行することも容易になる。
【００４５】
次に、前記の清掃、点検保守などの作業が終了した後に、前記のように取り外した両渡り板８，１０を取り付けるには、前記の取外し工程と逆の工程により取り付けることができる。
【００４６】
なお、前記の実施例では、渡り板８，１０を略垂直姿勢に起立した状態で取り外しが行えるようにしたが、渡り板８，１０を、水平に対して所望の角度に上方へ旋回した場合に取り外すことができるように前記の渡り板軸受１４を、その開口側の向きを定めて設置してもよい。
【００４７】
図８乃至図１５は本発明の実施例を示す。これを第２実施例とする。
【００４８】
本第２実施例は、図８及び図９に示すように、連結車両１，２間の連結通路に設けられる幌を２分割し、この分割幌５Ａ，５Ｂの開放側幌金枠３１，３２相互を連結するようにした分割型幌に本発明を適用した例である。
【００４９】
また、一方の分割幌５Ａ側には、渡り板の取付部材である一方の車両１側に取り付けられた一方の渡り板３３と、渡り板の取付部材である開放側幌金枠３１に取り付けられた他方の渡り板３４が設けられている。更に、他方の分割幌５Ｂ側には、渡り板の取付部材である他方の車両２側に取り付けられた一方の渡り板３５と、渡り板の取付部材である開放側幌金枠３２に取り付けられた他方の渡り板３６が設けられている。
【００５０】
更に、前記一方の渡り板３３，３５は夫々１枚で形成され、他方の渡り板３４，３６は、連結通路方向と直交する方向、すなわち通路幅方向に複数枚、図の例では３枚に分割して並列的に設けられている。この分割された中間の分割渡り板を３４ａ，３６ａとし、両側の分割渡り板を３４ｂ，３４ｃ及び３６ｂ，３６ｃとする。これら他方の分割渡り板３４，３６の先部は、その下面に固着したスリ板２１ａを介して一方の渡り板３３，３５の先部の上面に載置されている。
【００５１】
前記一方の車両１側の一方の渡り板３３は、前記第１実施例の取付手段７及び下降阻止手段２０と同様の構造によって一方の車両１に取り付けられている。また、他方の車両２側の一方の渡り板３５も前記第１実施例の取付手段７及び下降阻止手段２０と同様の構造によって他方の車両２に取り付けられている。そのため、これらの一方の渡り板３３，３６の取付構造の説明は省略する。
【００５２】
次に、前記一方の分割幌５Ａにおける他方の渡り板３４について図８乃至図１２により詳述する。
【００５３】
先ず、両側の分割渡り板３４ｂ，３４ｃのうちの一側の分割渡り板３４ｂについて説明する。
【００５４】
該分割渡り板３４ｂが位置する開放側幌金枠３１には、図１０及び図１１に示すように、幌金枠軸受４１ａ，４１ｂが固設され、該幌金枠軸受４１ａ，４１ｂには、連結通路６の横幅方向で、かつ水平に配置した軸穴４２ａ，４２ｂが形成されている。分割渡り板３４ｂの基部側の下面には取付部材４３ａ，４３ｂを介して横軸４４ａ，４４ｂが、前記軸穴４２ａ，４２ｂと同方向に固設され、該横軸４４ａ，４４ｂを軸穴４２ａ，４２ｂに、その連結通路６の中央Ｘ−Ｘ側の開口部４２ｃから抜き外し可能に差し込んで、渡り板３４ｂを幌金枠軸受４１ａ，４１ｂに回転可能に取り付けるようになっている。
【００５５】
なお、幌金枠軸受４１ａ，４１ｂ側に横軸４４ａ，４４ｂを設け、取付部材４３ａ，４３ｂに軸穴４２ａ，４２ｂを設けてもよい。
【００５６】
前記内側に位置する取付部材４３ｂには、前記横軸４４ｂと反対側の方向、すなわち、連結通路６の中央Ｘ−Ｘ部に向って横軸４５が水平方向に突出している。この横軸４５は前記第１実施例の横軸１２と同様の機能を有するものである。
【００５７】
次に、前記他側の分割渡り板３４ｃについて説明する。
【００５８】
該他側の分割渡り板３４ｃが位置する開放側幌金枠３１には、図８に示すように、前記一側の分割渡り板３４ｂ側と同様の幌金枠軸受４１ａ，４１ｂが、前記一側の分割渡り板３４ｂに対して連結通路６の中央Ｘ−Ｘを中心とした対称位置に設けられ、また、他側の分割渡り板３４ｃには前記一側の分割渡り板３４ｂ側と同様の横軸４４ａ，４４ｂと横軸４５が、前記一側の分割渡り板３４ｂに対して連結通路６の中央Ｘ−Ｘを中心として対称に設けられており、他側の分割渡り板３４ｃが前記一側の分割渡り板４３ｂと同様に回転可能に備えられている。この他側の分割渡り板３４ｂの取付構造は前記一側の分割渡り板４３ｂの取付構造と同様であるため、その説明は省略する。
【００５９】
次に前記中央部の分割渡り板３４ａについて図８及び図１２により説明する。
【００６０】
中央部の分割渡り板３４ａの基部側下面には、前記第１実施例の渡り板軸受１４と同様の渡り板軸受４６が取付座４９を介して固設されている。そして、図１２に示すように、該渡り板軸受４６を前記横軸４５に、前記第１実施例と同様に回転可能に嵌合して中央部の分割渡り板３４ａが取り付けられている。また、中央部の分割渡り板３４ａが位置する開放側幌金枠３１には前記第１実施例の軸受案内板１５と同様の軸受案内板４７が固設されているとともに前記スリ板１６と同様のスリ板４８が設けられており、中央部の分割渡り板３４ａが前記第１実施例の一方の渡り板８と同様に、略水平状態では取り外すことができず、略垂直状態において取り外すことができるようになっている。
【００６１】
なお、図１０において、５０，５１，５２は間座を示す。
【００６２】
また、他方の分割幌５Ｂにおける他方の渡り板３６の開放側幌金枠３２への取付構造は、前記一方の分割幌５Ａにおける他方の渡り板３４の取付構造と同様である。すなわち、両側の分割渡り板３６ｂ，３６ｃは前記両側の分割渡り板３４ｂ，３４ｃと同様の取付構造であり、中央部の分割渡り板３６ａは前記中央部の分割渡り板３４ａと同様の取付構造である。
【００６３】
前記第２実施例の構造において、各渡り板が図８乃至図１２に示すように取り付けられている状態では、車両１，２側に取り付けられた一方の渡り板３３，３５は前記第１実施例と同様に各横軸（図５の１２に相当する横軸）を中心として上下方向に旋回可能であるとともに下降阻止手段（図５の２０に相当する下降阻止手段）によって略水平状態からの下方への旋回が阻止されている。
【００６４】
また、開放側幌金枠３１，３２に取り付けられた各他方の分割渡り板３４ａ〜３４ｃ、３６ａ〜３６ｃは、各横軸４４ａ，４４ｂ，４５を中心として上下方向に旋回可能であるとともに、該各他方の分割渡り板３４ａ〜３４ｃ、３６ａ〜３６ｃの先部が前記一方の渡り板３３，３５上に支持される。更に、中央部の分割渡り板３４ａ，３６ａは、その渡り板軸受４６が図１２に示す状態にあり、前記第１実施例と同様に外れない。
【００６５】
また、連結車両１，２間において偏倚や伸縮が生じた場合には、一方の渡り板３３，３５と他方の渡り板３４，３６は、その重合部が摺動して追従移動する。
【００６６】
次に、連結部の清掃や点検保守を行うために、各渡り板を取り外す場合について説明する。
【００６７】
先ず、分割幌５Ａ側における中央の分割渡り板３４ａを、その先端を持って、図１３に示すように、横軸４５と渡り板軸受４６の嵌合部を中心として上方へ旋回させて略垂直に起立させた後、図１４に示すように持ち上げて開放側幌金枠３１から外す。
【００６８】
次に、一側の分割渡り板３４ｂを、前記のように取り外された中央部の分割渡り板３４ａがあった方向、すなわち連結通路６の中央Ｘ−Ｘの方向（図１０に示す矢印Ｙ方向）へ移動させて、図１５に示すように横軸４４ａ，４４ｂを幌金枠軸受４１ａ，４１ｂから外す。これにより、一側の分割渡り板３４ｂを開放側幌金枠３１から外すことができる。次に、他側の分割渡り板３４ｃも同様にして外す。なお、この一側の分割渡り板３４ｂと他側の分割渡り板３４ｃの取り外す順序は問わない。
【００６９】
次に、一方の渡り板３３を前記第１実施例と同様にして取り外す。
【００７０】
次に、分割幌５Ｂ側の各渡り板も前記分割幌５Ａ側と同様にして開放側幌金枠３２から取り外す。
【００７１】
なお、分割幌５Ａ側の渡り板と分割幌５Ｂ側の渡り板の取り外す順序は問わない。
【００７２】
以上により、全ての渡り板が取り外されて、連結部での清掃や点検保守などの作業が容易になる。
【００７３】
次に、前記のように各渡り板を取り外した状態から、その各渡り板を取り付ける場合は、前記の取外し工程とは逆の工程により行う。
【００７４】
なお、本第２実施例においても、各渡り板を取り外す場合の起立角度は、前記第１実施例と同様に略垂直に限らず、所望の角度にしてもよい。
【００７５】
なお、前記第１実施例及び第２実施例のほかに、本発明を次のような形態で適用することができる。
【００７６】
前記第１実施例において、一方の渡り板８は、１枚板としてその取付構造をそのままとし、他方の渡り板１０を、連結通路６の幅方向に２分割してこれを並列状態に配置するとともに、その分割された各渡り板を夫々前記第１実施例と同様の構造で車両に取り外し可能に取り付けるようにしてもよい。更に、この他方の渡り板１０を、前記第２実施例の開放側幌金枠３１に取り付けた他方の渡り板３４のように、中央の分割渡り板３４ａと両側の分割渡り板３４ｂ，３４ｃに３分割してこれらを前記第２実施例と同様の構造で車両２に取り外し可能に取り付けてもよい。
【００７７】
また、分割型幌を用いる第２実施例において、その第２実施例における開放側金枠３１，３２に取り付けられる他方の渡り板３４，３６、すなわち、夫々３枚に分割された渡り板を、前記第１実施例における１枚からなる他方の渡り板１０に替えてもよい。
【００７８】
したがって、連結車両における連結通路部の幅や長さ、更には一枚型か分割型かの幌の形態等の諸条件に合わせて、前記第１及び第２実施例に示した各渡り板を所望に選定して組み合わせて使用することができる。
【００７９】
【発明の効果】
以上のようであるから、本発明によれば、渡り板の下部空間において清掃や点検保守などの作業を行う場合には、渡り板を取り外すことができるため、前記従来のように渡り板を単に起立させるものに比べて、清掃や点検保守などの作業が容易に行えるとともに作業者の通行も容易になる。更に、連結通路の幅方向に複数に分割された渡り板の取り外し作業は、一部の分割渡り板を上方へ旋回させた後に持ち上げて外し、他の分割渡り板を移動させて外すことで行えるため、その取り外し作業が極めて簡単に行える。
【００８０】
更に、渡り板が取り外されるため、連結車両の分割、併合作業が、前記従来のように渡り板が取り付けられたままの場合に比べて容易になる。

Rotation and descent from the substantially horizontal state of one of the transition plates 8 is prevented, and the angle (levelness) with the horizontal plane of one of the transition plates 8 is adjusted by rotating the receiver 8 and adjusting its height. It can be adjusted. The support plate 15c and the metal receiver 18 constitute a bridge plate lowering prevention means 20. The lowering prevention means 20 is not limited to the above-described configuration, and may support the connecting plate 8 directly by the support plate 15c, or may support the connecting plate 8 with another structure.
[0032]
The attachment means 9 for the other transition plate 10 shown in FIGS. 1 and 2 has the same structure as the attachment means 7 for the one transition plate 8. That is, the vehicle body side bearing 11, the horizontal shaft 12, the mounting seat 13, the transition plate bearing 14, the bearing guide plate 15, and the slot plate 16 are the same as described above. Therefore, the description of the structure of the attachment means 9 of the other transition plate 10 is omitted.
[0033]
Note that the support plate 15c and the metal receiver 18 (lowering prevention means 20) are not provided on the other transition plate 10 side. Further, as shown in FIGS. 1 and 2, a slit plate 21 is fixed to the lower surface of the tip portion of the other jumper plate 10, and the tip portion of the other jumper plate 10 is connected to the one jumper plate via the slit plate 21. 8 is placed on the top surface of the tip.

In the above structure, as shown in FIG. 5, the transition plate bearing 14 of one of the transition plates 8 is fitted to the horizontal shaft 12, and the lower surface of the one transition plate 8 is placed on a metal receiver 18 that is a lowering prevention means 20. Then, one of the transition plates 8 is attached in a substantially horizontal lying state, and the other transition plate 10 is also attached in the same manner as the one of the transition plates 8 and the operation is performed in a state where the front portion is placed on the one transition plate 8. explain.
[0035]
In this state, since the transition plate bearing 14 of one of the transition plates 8 is rotatably fitted to the horizontal shaft 12, when there is vertical vibration during traveling of the vehicles 1 and 2, one of the transition plates 8 is against this vibration. It is possible to smoothly follow and turn in the vertical direction around the horizontal axis 12. Similarly, the other transition plate 10 can also follow and turn in the vertical direction.
[0036]
Further, although the opening portion 14 c is formed in the transition plate bearing 14, the inner surface 16 a of the slip plate 16 that is the disengagement prevention means 17 is close to the outer surface 14 e of the transition plate bearing 14, so that one of the transition plates 8 is substantially horizontal. In the posture or a posture slightly swung upward from the horizontal state, the semicircular portion 14 a of the transition plate bearing 14 is sandwiched between the horizontal shaft 12 and the slit plate 16, and the lower straight portion 14 b of the transition plate bearing 14 is connected to the horizontal shaft 12. The one crossing plate 8 does not come off when locked.
[0037]
The other jumper plate 10 can also be turned and cannot be removed in the same manner as the first jumper plate 8.
[0038]
Further, one of the crossing plates 8 is prevented from turning downward by the descending prevention means 20, and the set substantially horizontal posture is maintained.
[0039]
In addition, the other jumper plate 10 is not provided with the lowering prevention means 20, but the other jumper plate 10 is overlapped on the upper surface of the first jumper plate 8. It is also prevented from turning downward from the substantially horizontal state.
[0040]
In addition, when deviation or expansion / contraction occurs between the connected vehicles 1 and 2, the one overlapping plate 8 and the other connecting plate 10 slide and follow the overlapping portions.
[0041]
Next, the case where the crossover plates 8 and 10 are removed from the substantially horizontal installation state of the crossover plates 8 and 10 in order to clean the connecting portion and perform inspection and maintenance will be described.
[0042]
In this case, as shown in FIG. 6, one of the jumper plates 8 is pivoted upward about the fitting portion of the horizontal shaft 12 and the jumper plate bearing 14 as shown in FIG. As a result, the bridge plate bearing 14 rotates in the same manner so that the opening 14 c faces downward and the linear portion 14 b is substantially parallel to the inner surface 16 a of the slot plate 16. Accordingly, by lifting one of the transition plates 8 from the standing state, the one transition plate 8 can be removed from the vehicle 1 as shown in FIG.
[0043]
The other transition plate 10 is also removed in the same manner as described above.
[0044]
In this way, by removing the crossover plates 8 and 10, it is possible to easily perform cleaning and inspection / maintenance work at the bottom in the hood as compared with the conventional case where the crossover plate is simply raised, and the operator can connect the connecting passage portion. It is also easy to pass.
[0045]
Next, after the work such as cleaning and inspection / maintenance is completed, in order to attach the bridge plates 8 and 10 removed as described above, they can be attached by a process reverse to the above-described removal process.
[0046]
In the above-described embodiment, the bridge plates 8 and 10 can be detached while standing in a substantially vertical posture. However, the bridge plates 8 and 10 are removed when the bridge plates 8 and 10 are turned upward at a desired angle with respect to the horizontal. The bridge plate bearing 14 may be installed with its orientation on the opening side determined.

【The invention's effect】
  As it is above,BookAccording to the invention, when performing work such as cleaning and inspection maintenance in the lower space of the transition board, the transition board can be removed, so that cleaning and inspection maintenance are performed as compared with the conventional one in which the transition board is simply raised. It is possible to easily perform operations such as the above, and also facilitate the passage of workers. Furthermore,Divided into multiple in the width direction of the connecting passageRemoval work of the transition boardSome splitLift after turning the bridge plate upwardRemove and move the other split jumper to removeTherefore, the removal work can be performed very easily.
[0080]
Furthermore, since the transition board is removed, the splitting and merging work of the connected vehicles is facilitated as compared with the case where the transition board is still attached as in the prior art.
