Description

【０００１】
【発明の属する技術分野】
本発明は、軌道走行車両の軌道載置方法及び車体移動装置に関し、更に詳細には、複線区間の一方側の鉄道走行用のレール上に軌道走行車両を載置させるための軌道載置方法及び車体移動装置に関する。
【０００２】
【従来の技術】
鉄道走行用のレールに沿って架設されたトロリ線や各種設備の保守、点検等を行なう場合には、鉄道走行用のレール上を走行自在ないわゆる軌道作業車が用いられることが多く、この軌道作業車としては一般の道路走行も可能な軌陸作業車が用いられることが多い。この軌陸作業車は、トラック車両をベースに構成されて、その車体に起伏動且つ旋回動自在に取り付けられて伸縮動自在に構成されたブームと、ブームの先端部に設けられた作業台とを有して作業台を所望の高所位置に移動させる作業装置が設けられている。
【０００３】
軌陸作業車には、道路上を走行するための道路走行用車輪とレール上を走行するための軌道走行用鉄輪とが設けられ、軌陸作業車は、道路上を走行するときは軌道走行用鉄輪を車体に格納して道路走行用車輪を接地させ、レール上を走行するときは軌道走行用鉄輪を軌道上に張り出させるように構成されている。また、軌陸作業車には車体をレール上に載置させるための車体移動装置が設けられ、この車体移動装置は車体の中央下部に取り付けられている。
【０００４】
車体移動装置は車体の中央下部に取り付けられて垂直下方へ伸縮動自在なセンタジャッキと、センタジャッキの下部に水平方向に回転動可能に取り付けられた回転部材と、回転部材の下部に水平方向にスライド移動可能に取り付けられて下面が接地するスライド部とを有して構成されている。
【０００５】
この車体移動装置を用いて軌陸作業車をレール上に載置させるには、作業現場近くの踏切まで車両を道路走行用車輪によって道路上を走行させ、レールの中間位置に車体移動装置の回転部材の回転中心軸線がくるように車両を踏切上に停止させる。このような状態で、車体移動装置は前後に延びるレールに対して左右方向に車体をスライド移動させることができるような姿勢にある。そして、センタジャッキを伸長動させてスライド部を踏切内のレールと交差する道路の道路踏切部の路面上に接地させて道路走行用車輪を路面上から浮上させる。なお、道路踏切部の路面の高さはレールの軌道面と略同一高さである。そして、作業者が車体を押圧して接地しているスライド部に対して回転部材を回転動させて、車体をレールと略平行な状態にさせる。このとき、レールの上方に軌道走行用鉄輪が対向して位置していない場合には、車体移動装置によりスライド部に対して回転部材をレール側にスライド移動させて、レールに対する軌道走行用鉄輪の横方向の位置ずれを調整する。そして、軌道走行用鉄輪をレール上に張り出させ、センタジャッキを縮小動させて軌道走行用鉄輪をレール上に載置させる。
【０００６】
【発明が解決しようとする課題】
しかしながら、複線区間の踏切内において、一方側のレール（以下、「載置レール」と記す。）上に軌陸作業車を載置させる場合、車体移動装置が載置レール間に位置するように車両を踏切内に移動させると、前後長さが長い車両では、車両の先端部が載置レールに隣接して敷設された他方側の一対のレール（以下、「隣接レール」と記す。）を通る電車に接触する虞が生じる。このため、車体を載置レール上に載置させる作業を行なうときには、隣接レール上を通る電車を一時的に停止させなければならないとういう問題が生じる。
【０００７】
そこで、隣接レールを通る電車に接触しないように、踏切内において隣接レールを通る電車に接触しない範囲内で載置レールを跨ぐ位置に車両を移動させればよいが、一般的なトラック車両は前後方向の長さが長いので、このように車両を移動させると、載置レールとこれに載置される軌道走行用鉄輪との横方向の位置ずれ量が大きくなる。このため、回転部材がスライド部に対して手動でスライド移動可能に構成されていると、車体を載置レール側に移動させる作業が煩わしいという問題が生じる。
【０００８】
また、載置レール上に載置された軌陸作業車により作業が行なわれた後に、車両を載置レールから取り外す場合、反対側レール上を通る電車の間合いによっては、作業時間が制約されるとういう問題が生じる。
【０００９】
本発明は、このような問題に鑑みてなされたものであり、複線区間の一方側の載置レール上に軌道走行車両を載置させる場合、車体を載置レール側に移動させる作業が容易であり、隣接レール上を通る電車を停止させず、この電車の間合いによって作業時間が制約されることのない軌道走行車両の軌道載置方法及び車体移動装置を提供することを目的とする。
【００１０】
【課題を解決するための手段】
前記課題を解決するために本発明の軌道走行車両の軌道載置方法は、道路上を走行するための道路走行用車輪（例えば、実施形態における前輪７、後輪８）と、軌道上を走行するための軌道走行用鉄輪（例えば、実施形態における鉄輪２５）とを有し、道路上を走行するときは軌道走行用鉄輪を車体に格納して道路走行用車輪を接地させ、軌道上を走行するときは軌道走行用鉄輪を軌道上に張り出すように構成され、車体の略中央下部に取り付けられて車体下部に格納される格納位置と下方に張り出して車体を持ち上げ支持する張出位置との間で伸縮動自在なセンタジャッキと、センタジャッキの下部に回転動可能に取り付けられた回転部材と、回転部材の下部に回転部材との間で水平方向に相対スライド移動可能に取り付けられて下面が接地するスライド部とを有してなる車体移動装置を備えて構成された軌道走行車両（例えば、実施形態における軌道作業車１）の軌道載置方法であって、軌道走行用鉄輪を車体に格納させ、且つセンタジャッキを格納位置まで縮小動させて車体移動装置を道路走行用車輪よりも上方へ引き上げた状態で道路走行用車輪により走行して、車体の前端部が載置対象軌道（例えば、実施形態における載置レールＲ）に隣接して敷設された隣接軌道（例えば、実施形態における隣接レールＲ’）を通る電車に接触しない範囲内で載置対象軌道を跨ぐ位置に車体を移動させ、センタジャッキを張出位置まで張り出し、スライド部を接地させて車体を持ち上げ支持して、道路走行用車輪を非接地状態にさせ、車体が載置対象軌道と略平行になるように回転部材に対して車体を回転させ、この状態で、回転部材の回転中心軸線の位置が載置対象軌道の軌道中心軸線よりも隣接軌道から離反する側にずれ、載置対象軌道に対して軌道走行用鉄輪が横方向にずれた状態となるときには、車体が載置対象軌道側へスライド移動するように接地したスライド部に対して回転部材をスライド移動させて載置対象軌道の上方に対向する位置まで軌道走行用鉄輪を移動させ、軌道走行用鉄輪を載置対象軌道上に張り出させ、センタジャッキを格納位置まで縮小動させて軌道走行用鉄輪を載置対象軌道上に載置させる。
【００１１】
上記構成の軌道載置方法によれば、軌道走行車両を載置対象軌道上に載置させる場合、車体の前端部が隣接軌道を通る電車に接触しない範囲内で載置対象軌道を跨ぐ位置に車体を移動させ、その位置で車体が軌道と平行になるように車体を回転させ、この状態で、回転部材の回転中心軸線の位置が軌道中心軸線よりも隣接軌道から離反する側にずれ、且つ載置対象軌道に対して軌道走行用鉄輪が横方向にずれた状態となるときには、車体移動装置により車体を載置対象軌道側にスライド移動させて、載置対象軌道の上方に対向する位置まで軌道走行用鉄輪を移動させることで、軌道走行車両を載置対象軌道上に載置させる過程において、車両が隣接軌道を通る電車に接触する虞はなく、隣接軌道を通る電車を一時的に停止させる必要性を無くすことができる。また、隣接軌道上を通る電車の間合いに影響されずに、載置対象軌道上に載置された軌陸作業車を載置対象軌道から取り外すことができ、載置対象軌道上に載置された軌陸作業車による作業の作業時間を延長することができる。
【００１２】
上記構成の軌道載置方法において、載置対象軌道に対して軌道走行用鉄輪が横方向にずれた状態となるときに、接地したスライド部に対して車体を載置対象軌道側にスライド移動させることができるスライドストロークの大きさが、載置対象軌道とこれに載置される軌道走行用鉄輪との横方向の位置ずれ量よりも小さい場合には、センタジャッキを格納位置まで縮小動させて道路走行用車輪を接地させ、回転部材に対して隣接軌道から離反する側に移動しているスライド部が隣接軌道側に接近移動するように、スライド部を回転部材に対して相対スライド移動させ、センタジャッキを張出位置まで伸長動させて道路走行用車輪を非接地状態にさせ、接地したスライド部に対して回転部材を介して車体を載置対象軌道側へスライド移動させるスライド作動を繰返すようにしてもよい。
【００１３】
上記構成の軌道載置方法によれば、接地したスライド部に対する回転部材の載置対象軌道側へのスライドストロークの大きさが、載置対象軌道とこれに載置される軌道走行用鉄輪との横方向の位置ずれ量よりも小さい場合には、回転部材をスライド部に対してスライド移動させても、載置対象軌道の上方に軌道走行用鉄輪を対向して位置させることができない。このような場合には、スライド部を一旦上方へ引き上げて道路走行用車輪を接地させた後に、回転部材に対してスライド部を隣接軌道から離反する側に相対スライド移動させる。そして、再びスライド部を接地させて道路走行用車輪を非接地状態にした後に、再び回転部材をスライド部に対して載置対象軌道側へスライド移動させる。このようなスライド作動を繰り返すことで、位置ずれ量の大きさに拘わらず載置対象軌道から横方向にずれた軌道走行用鉄輪を載置対象軌道の上方位置に対向配置させることができる。
【００１４】
本発明の軌道走行車両の車体移動装置は、道路上を走行するための道路走行用車輪と、軌道上を走行するための軌道走行用鉄輪とを有し、道路上を走行するときは軌道走行用鉄輪を車体に格納して道路走行用車輪を接地させ、軌道上を走行するときは軌道走行用鉄輪を軌道上に張り出すように構成され、車体の略中央下部に取り付けられて車体下部に格納される格納位置と下方に張り出して車体を持ち上げ支持する張出位置との間で伸縮動自在なセンタジャッキと、センタジャッキの下部に回転動可能に取り付けられた回転部材と、回転部材の下部に水平方向に相対スライド移動可能に取り付けられて下面が接地するスライド部とを有してなる車体移動装置を備えて構成された軌道走行車両の車体移動装置であって、回転部材は回転アクチュエータにより回転駆動可能に構成され、スライド部はスライドアクチュエータにより水平方向にスライド移動可能に構成され、スライド部に取り付けられて下方へ伸縮動自在であり、スライド部の下面が接地されて車体が持ち上げ支持された状態において、下端部を接地させてスライド部を水平状態に調整する複数の水平調整ジャッキ（例えば、実施形態における水平調整シリンダ５７）を有して構成されてもよい。
【００１５】
上記構成の車体移動装置によれば、スライド部に下方へ伸縮動自在な複数の水平調整ジャッキを設けるだけで、接地状態にあるスライド部が傾いている場合でも、複数の水平ジャッキを伸縮動させることで、スライド部を水平状態にしてスライド部に繋がる車体を水平状態にすることができる。
【００１６】
【発明の実施の形態】
以下、本発明の好ましい実施の形態を図１から図７に基づいて説明する。本実施の形態は、レール上を走行する時に軌道走行用車輪である鉄輪をレール上に張り出して当接させ、且つ道路走行用の前輪をレール上から浮上させるとともに、道路走行用の後輪をレールに当接させた状態で回転駆動させる軌陸作業車の態様を示す。先ず、本発明に係わる車体移動装置を説明する前に、この車体移動装置を搭載する軌陸作業車について説明する。
【００１７】
軌陸作業車１は、図１に示すように、道路上を走行するトラック車両をベースに構成されており、車体３の前側に運転キャビン５を有し、運転キャビン５の下方の車体３の左右両側部に一対の前輪７を回転自在に有し、車体後部の両側部に一対の後輪８を回転駆動可能に有して道路走行可能である。運転キャビン５よりも車両後方側の車体３には上方へ延びた載置台９が設置されている。載置台９は車体３から上方へ突設された複数の支柱９ａと、複数の支柱９ａの上端部に水平方向に延びた状態で取り付けられた天板９ｂとを有して構成されている。天板９ｂの上部にはシザースリンク機構１２を構成して上下に伸縮動可能に構成された昇降装置１１が設置され、昇降装置１１の上端部に作業台１７が取り付けられている。
【００１８】
このように構成された軌陸作業車１の車体３には、車両をレール上で走行させるときに用いられる軌道走行装置２０が取り付けられている。軌道走行装置２０は運転キャビン５の前端部の左右両側部、及び一対の後輪８よりも車両後方側の車体後端部の左右両側部にそれぞれ配設されている。軌道走行装置２０は、図２に示すように、車体３の左右両側部のそれぞれに下方へ突設された支持フレーム２１と、支持フレーム２１に上下揺動自在に枢結された鉄輪保持フレーム２３と、鉄輪保持フレーム２３に回転自在に取り付けられた鉄輪２５と、鉄輪保持フレーム２３を上下揺動させる図２に示す昇降シリンダ２７とを有して構成されている。
【００１９】
支持フレーム２１は車体左右方向に所定の間隔を有して対向配置された一対の側板部２１ａを有してなり、一対の側板部２１ａの下端部に鉄輪保持フレーム２３が上下揺動自在に枢結されている。昇降シリンダ２７は支持フレーム２１の一対の側板部２１ａ間に配設され、一端部が車体３に枢結され、他端部が鉄輪保持フレ２３の上部に枢結されている。図１に示す転キャビン５の前端部に配設された昇降シリンダ（図示せず）が伸縮動すると、前輪前側に配設された鉄輪保持フレーム２３が車両前方側に上下揺動し、図１に示す後輪８の後側に配設された図２に示す昇降シリンダ２７が伸縮動すると、図１に示す後輪後側に配設された鉄輪保持フレーム２３が車両前方側に上下揺動する。
【００２０】
鉄輪保持フレーム２３は逆Ｕ字状であり、下方へ延びる一対の保持板部２３ａを有して構成されている。一対の保持板部２３ａ間に円盤状の鉄輪２５が回転自在に取り付けられ、鉄輪２５の車体内側端部には径方向外側に突出するフランジ部２５ａが環状に形成されている。このように形成された鉄輪２５を回転自在に保持する鉄輪保持フレーム２３は、車両が道路面上に載置されている場合に、図１に示す前輪７及び後輪８が道路面に当接された状態で、鉄輪２５を道路面から上方に離反させて車体３に格納させる鉄輪格納位置と、車両が載置される載置レールＲ上に載置されている場合に、鉄輪２５を載置レールＲ上に当接させた状態で、図１に示す前輪７を載置レールＲから離反させるとともに、後輪８を載置レールＲ上に接触させる鉄輪完全張出位置に移動可能に構成されている。
【００２１】
次に、このように構成された軌陸作業車１を載置レールＲ上に載置させる車体移動装置について説明する。車体移動装置４０は、図１に示すブーム１１が車両に格納された状態における車両の重心位置の近傍に配設され、前輪７及び後輪８間の車体３の下部に下方へ突出した状態で取り付けられている。車体移動装置４０は、図３に示すように、車体３の中央下部に取り付けられて垂直下方へ伸縮動自在な一対のセンタジャッキ４３、センタジャッキ４３の下部に取り付けられて水平方向に延びる接続板４４、接続板４４の略中央下部に取り付けられた回転機構部６０、回転機構部６０の下部に取り付けられた回転部材４５、下面が接地された状態で回転部材４５を水平方向にスライド移動させるスライド部４９と、スライド部４９の縁部に取り付けられた複数の水平調整ジャッキ５７とを有して構成されている。
【００２２】
一対のセンタジャッキ４３は前後に延びる車両の車両中心軸線Ｓに対して左右対称な位置に配設され、車体下部に格納される格納位置と下方に張り出して車体３を持ち上げ支持する張出位置との間で伸縮動自在である。接続板４４は平面視において矩形状であり、センタジャッキ４３の下端部に接続板４４が水平方向に延びた状態で固着されている。接続板４４の略中央部と回転部材４５との間には前述した回転機構部６０が挟装されている。回転機構部６０は、図４に示すように、接続板４４の下面から下方へ突設された円筒状の回転軸部６１の下部に嵌合して接続板４４を回転軸部６１の回転中心軸線Ｔを回転中心として回転自在に保持するターンテーブル６３と、ターンテーブル６３を回転駆動させる駆動部６９とを有して構成されている。
【００２３】
ターンテーブル６３は内側に円環状の図示しないインナーレースと、インナーレースの径方向外側に回転中心軸線Ｔを回転中心として回転可能に嵌合する環状のアウターレース６４とを有してなり、インナーレースの中央部に回転軸部６１の下端部が固着された状態で取り付けられている。このため、インナーレースと接続板４４は回転軸部６１を介して一体化されている。アウターレース６４の外周には固定ギア６４ａが形成され、アウターレース６４の中央下部には下方へ突出する突出部５５が形成され、この突出部５５の下部が回転部材４５の中央部上面に固着された状態で取り付けられている。このため、アウターレース６４と回転部材４５は一体化されている。
【００２４】
駆動部６９は接続板４４の周縁上部に設置され、軸部７０ａが接続板４４を回転自在に貫いて下方へ延びた回転モータ７０と、軸部７０ａの下端部に固定された状態で取り付けられてアウターレース６４の固定ギア６４ａに歯合する駆動ギア７１とを有して構成されている。このため、スライド部４９が接地された状態で駆動ギア７１が回転駆動すると、駆動ギア７１が固定ギア６４ａの周りを自転しながら公転して接続板４４を回転させる。一方、スライド部４９が非接地状態で駆動ギア７１が回転駆動すると、駆動ギア７１の回転方向と反対方向にスライド部４９が回転動する。なお、ターンテーブル６３は、スライド部４９が非接地状態になったときに、アウターレース６４がインナーレースから抜脱しないように構成されている。
【００２５】
ターンテーブル６３を固着する回転部材４５は、側面視においてＵ字状をなし、水平方向に延びる底部４５ａ、底部４５ａの左右両端部のそれぞれから上方へ延びる側部４５ｂ、及び一対の側部４５ｂのそれぞれの頂部から外側へ突出して水平に延びるフランジ部４５ｃを有して形成されている。
【００２６】
回転部材４５と相対スライド移動するスライド部４９は、回転部材４５のフランジ部４５ｃの下方にフランジ部４５ｃに沿って延びる一対のスライドレール５２と、回転部材４５をスライド移動させる図５に示すスライドシリンダ５４とを有して構成されている。スライドレール５２には図３に示すフランジ部５０ｃの両端部に固着された係合部材５３が係合され、この係合部材５３により回転部材４５の相対スライド移動を案内している。スライドシリンダ５４は、図５に示すように、一端部がスライドレール５２の内側面に枢結され、他端部が回転部材４５の端部に枢結されて、回転部材４５をスライドレール５２に沿ってスライド移動させる。このため、図３に示すスライド部４９が接地された状態でスライドシリンダ５４を伸縮動させると、スライドレール５２に対して回転部材４５がスライドレール５２に沿ってスライド移動して、回転部材４５に繋がった図３に示す接続板４４を介して車体３をスライドレール５２の延びる方向と同一方向にスライド移動させることができる。また、図３に示すスライド部４９が非接地状態にあるときにスライドシリンダ５４を伸縮動させると、回転部材４５に対してスライド部４９をスライド移動させて、スライドレール５２に対する回転部材４５の相対位置を変えることができる。
【００２７】
このように構成されたスライドレール５２の両端部の底部には、図３に示すように、これらを載置させた状態で取り付けられた板状の絶縁部材５６が設けられている。なお、車体移動装置４０の作動の詳細は後述する。
【００２８】
一対のスライドレール５２の各両端部には、垂直下方へ伸縮動自在に構成された水平調整シリンダ５７が固着された状態で取り付けられている。この水平調整シリンダ５７は、スライド部４９が接地された状態でスライド部４９が水平に対して傾斜しているときに、水平調整シリンダ５７を伸縮動させると、スライド部４９を水平状態にすることができる。その結果として、水平調整シリンダ５７により車体３を水平状態にすることができる。
【００２９】
なお、車体移動装置４０のセンタジャッキ４３、水平調整シリンダ５７及び図５に示すスライドシリンダ５４は、これらのシリンダの作動を制御する図示しない作動制御装置に繋がれ、この作動制御装置はケーブル（図示せず）を介して操作装置（図示せず）に電気的に接続され、この操作装置の操作に応じて作動制御装置がこれらのシリンダを作動させる。このため、車両外部から操作装置を操作して車体移動装置４０を遠隔操作することができる。
【００３０】
次に、前述した車体移動装置４０を用いて軌陸作業車１を載置レールＲ上に載置させる本発明に係わる軌道載置方法について説明する。先ず、図１に示す車両において、軌道走行用の鉄輪２５を車体３に格納させ、且つ車体移動装置４０のセンタジャッキ４３を格納位置まで縮小動させて、スライド部４９を前輪７及び後輪８よりも上方位置に引き上げ、前輪７及び後輪８を図示しない道路面上に当接させた状態（道路走行状態）にする。そして、図６（ａ）に示すように、図１に示す前輪７及び後輪８により車両を作業現場に近い踏切８０まで道路走行移動させ、踏切８０内において車体３の前端部（即ち、運転キャビン５の前端部）が載置レールＲに隣接して敷設された隣接レールＲ’を通る電車８２に接触しない範囲Ａ内において載置レールＲを跨ぐ位置に車体３を移動させる。
【００３１】
そして、前述した操作装置（図示せず）を操作して、スライド部４９が載置レールＲの延びる方向と同一方向になるように図４に示す回転モータ７０を駆動させて、図４に示す回転部材４５に対してスライド部４９を回転動させる。そして、図４に示すセンタジャッキ４３を張出位置まで伸長動させ、踏切８０内を交差する道路Ｄの道路踏切部Ｄ’の路面上にスライド部４９を接地させて図１に示す前輪７及び後輪８を道路踏切部Ｄ’の路面から浮上させる。なお、道路踏切部Ｄ’の路面の高さは載置レールＲの軌道面と略同一の高さに形成されている。
【００３２】
そして、図６（ｂ）に示すように、操作装置を操作して図１に示す車体３が載置レールＲと略平行にように図４に示す回転モータ７０を駆動させてスライド部４９に対して回転部材４５を回転させる。なお、一般的なトラック車両では車両の前後方向の長さは長いので、車体３が載置レールＲと略平行にされた状態では、図４に示す回転部材４５の回転中心軸線Ｔの位置が載置レールＲの軌道中心軸線Ｕよりも隣接レールＲ’から離反する側にずれ、載置レールＲに対して軌道走行用の鉄輪２５が横方向にずれた状態となる。このようなときには、図７（ｃ）に示すように、操作装置を操作して車体３が載置レールＲ側にスライド移動されるように図５に示すスライドシリンダ５４を伸縮動させて、図３に示す接地状態にあるスライド部４９に対して回転部材４５を載置レールＲ側にスライド移動させる。ここで、スライド部４９に対して図３に示す回転部材４５が載置レールＲ側にスライド移動可能なスライドストロークの大きさＬｓが、載置レールＲとこれに載置される軌道走行用の鉄輪２５との横方向の位置ずれ量Ｌｒよりも小さい場合には、鉄輪２５を載置レールＲの上方位置に対向配置させることができなくなる。
【００３３】
このような場合には、図３に示すように、操作装置を操作してセンタジャッキ４３を格納位置まで縮小動させて、スライド部４９を上方へ引き上げて道路踏切部Ｄ’の路面から浮上させて、図１に示す前輪７及び後輪８を接地させる。そして、操作装置を操作して、図３に示すように、スライド部４９の隣接レールＲ’側端部に移動している回転部材４５’がスライド部４９の隣接レールＲ’から離反する側（図３の上部側）に移動するように、回転部材４５に対してスライド部４９を相対スライド移動させる（図３の下側）。そして、センタジャッキ４３を張出位置まで伸長動させて、スライド部４９を、図７（ｄ）に示すように、道路踏切部Ｄ’の路面に接地させて、図１に示す前輪７及び後輪８を道路踏切部Ｄ’の路面から浮上させる。そして、操作装置を操作して、接地しているスライド部４９に対して図３に示す回転部材４５を載置レールＲ側へスライド移動させる（図３の下側）。なお、スライド部４９を載置レールＲ側にスライド移動させてから、さらにスライド部４９を載置レールＲ側にスライド移動させるまでの一連の動作を、以下「スライド作動」と呼ぶ。
【００３４】
そして、スライド部４９の載置レールＲ側への最初のスライド移動又は１回目のスライド作動により載置レールＲの上方に鉄輪２５が対向配置されると、図２に示す軌道走行装置２０の昇降シリンダ２７を伸長動させて、鉄輪保持フレーム２３を前述した鉄輪完全張出位置に移動させて鉄輪２５を載置レールＲ上に張り出す。そして、図３に示すセンタジャッキ４３を格納位置まで縮小動させて鉄輪２５を載置レールＲ上に当接させて、車両が載置レールＲ上に載置される。
【００３５】
なお、１回目のスライド作動によっても載置レールＲの上方に鉄輪２５が対向配置されない場合には、載置レールＲの上方に鉄輪２５が移動するまで前述したスライド作動を繰り返す。
【００３６】
このように、軌陸作業車１を載置レールＲ上に載置させる場合、図６（ａ）に示すように、運転キャビン５の前端部が隣接レールＲ’を通る電車８２に接触しないような範囲Ａ内に車体３を移動させてから、前述した車体移動装置４０の一連の動作を経て、図７（ｄ）に示す鉄輪２５が載置レールＲの上方位置に対向配置されて車両が載置レールＲ上に載置される。このため、軌陸作業車１を載置レールＲ上に載置させる過程において、車両が隣接レールＲ’を通る電車８２に接触する虞はなく、隣接レールＲ’を通る電車８２を一時的に停止させる必要性を無くすことができる。また、隣接レールＲ’上を通る電車８２の間合いに影響されずに、載置レールＲ上に載置された軌陸作業車１を載置レールＲから取り外すことができ、載置レールＲ上に載置された軌陸作業車１による作業の作業時間を延長することが可能になる。また、載置レールＲに対して軌道走行用の鉄輪２５が横方向にずれた状態にあるときに、車体３のスライド移動は操作装置の遠隔操作によりスライドシリンダ５４を作動させればよいので、このスライド移動を容易に行なうことができる。
【００３７】
また、回転部材４５の載置レールＲ側への最初のスライド移動によっても鉄輪２５が載置レールＲの上方に対向配置されない場合には、前述したスライド作動を１回以上繰り返すことで、鉄輪２５を載置レールＲに対向させた位置に必ず移動させることができる。
【００３８】
なお、本発明に係わる車体移動装置４０は、鉄輪２５が載置レールＲから脱線した場合でも、前述した軌道載置方法に準じて車体移動装置４０を動作させることで、脱線した鉄輪２５を再び載置レールＲ上に当接させた状態に戻すことができる。
【００３９】
また、前述した実施の形態では、載置レールＲ上を走行する時に鉄輪２５を載置レールＲ上に張り出して当接させ、且つ道路走行用の前輪７を載置レールＲ上から浮上させ、道路走行用の後輪８を載置レールＲに当接させるように構成された軌陸作業車１を示したが、軌陸作業車としては、鉄輪２５を載置レールＲ上に当接させた状態で、前輪７及び後輪８を載置レールＲ上から浮上させ又は前輪７及び後輪８を載置レールＲ上に接地させるように構成されたものでもよい。

The present invention relates to a track mounting method for a track running vehicle and a vehicle body moving device, and more particularly, to a track mounting method for mounting a track running vehicle on a rail for rail running on one side of a double track section and a track mounting method. The present invention relates to a vehicle body moving device.
[0002]
[Prior art]
When performing maintenance, inspection, etc. of trolley wires and various facilities installed along rails for rail travel, so-called rail work vehicles that can travel on rails for rail travel are often used. As a work vehicle, a track-and-work vehicle capable of running on a general road is often used. This track-and-land work vehicle is configured based on a truck vehicle, and includes a boom that is attached to the vehicle body so as to be able to move up and down and swing freely, and that is configured to be expandable and contractible, and a work table provided at a tip end of the boom. A work device for moving the work table to a desired high position is provided.
[0003]
A track-and-ground work vehicle is provided with a road running wheel for running on a road and a track running iron wheel for running on a rail. Is stored in the vehicle body, the road traveling wheels are grounded, and when traveling on the rails, the track traveling iron wheels are projected on the track. Further, the track-and-land work vehicle is provided with a vehicle body moving device for mounting the vehicle body on a rail, and the vehicle body moving device is attached to a lower center portion of the vehicle body.
[0004]
The body moving device is a center jack that is attached to the lower center of the car body and that can expand and contract vertically, a rotating member that is attached to the lower part of the center jack so that it can rotate horizontally, and a horizontal member that is attached to the lower part of the rotating member. And a slide portion which is slidably mounted and whose lower surface is grounded.
[0005]
In order to place a track-and-land work vehicle on a rail using this body moving device, the vehicle is driven on a road by a road running wheel until a railroad crossing near a work site, and the rotating member of the body moving device is positioned at an intermediate position of the rail. The vehicle is stopped on the railroad crossing so that the rotation center axis of the vehicle comes. In such a state, the vehicle body moving device is in such a posture that the vehicle body can slide in the left-right direction with respect to the rail extending in the front-rear direction. Then, the center jack is extended and the slide portion is grounded on the road surface of the road crossing portion of the road intersecting with the rail in the railroad crossing, and the road running wheel is lifted from the road surface. The height of the road surface at the road crossing is approximately the same as the track surface of the rail. Then, the operator presses the vehicle body to rotate the rotating member with respect to the slide portion that is in contact with the ground, thereby bringing the vehicle body into a state substantially parallel to the rail. At this time, when the track running iron wheel is not located above the rail, the rotating member is slid toward the rail with respect to the slide portion by the vehicle body moving device, and the track running iron wheel with respect to the rail is moved. Adjust lateral misalignment. Then, the track running iron wheel is protruded on the rail, and the center jack is reduced to move the track running iron wheel on the rail.
[0006]
[Problems to be solved by the invention]
However, when a track-and-ground work vehicle is mounted on one rail (hereinafter, referred to as a “mounting rail”) within a railroad crossing of a double track section, the vehicle is moved so that the vehicle body moving device is positioned between the mounting rails. When the vehicle is moved into a railroad crossing, in a vehicle having a long front-rear length, the leading end of the vehicle passes through a pair of rails on the other side (hereinafter, referred to as “adjacent rails”) laid adjacent to the mounting rails. There is a risk of contact with the train. For this reason, when performing the work of mounting the vehicle body on the mounting rail, there is a problem that the train passing on the adjacent rail must be temporarily stopped.
[0007]
Therefore, the vehicle may be moved to a position that straddles the mounting rail within a range that does not contact the train passing through the adjacent rail in the railroad crossing so as not to come into contact with the train passing through the adjacent rail. Since the length in the direction is long, when the vehicle is moved in this manner, the amount of lateral displacement between the mounting rail and the track running iron wheel mounted on the mounting rail increases. For this reason, if the rotating member is configured to be manually slidable with respect to the sliding portion, there is a problem that the operation of moving the vehicle body to the mounting rail is troublesome.
[0008]
In addition, when the vehicle is removed from the mounting rail after the work is performed by the track-and-ground work vehicle mounted on the mounting rail, the work time may be restricted depending on the interval of the train passing on the opposite rail. Problem arises.
[0009]
The present invention has been made in view of such a problem, and when a track traveling vehicle is mounted on a mounting rail on one side of a double track section, an operation of moving the vehicle body to the mounting rail side is easy. In addition, an object of the present invention is to provide a track mounting method and a vehicle body moving device for a track traveling vehicle in which a train passing on an adjacent rail is not stopped and a work time is not restricted by the interval of the train.
[0010]
[Means for Solving the Problems]
In order to solve the above-mentioned problems, a track mounting method of a track running vehicle according to the present invention includes a road running wheel (for example, a front wheel 7 and a rear wheel 8 in the embodiment) for running on a road, and running on a track. When traveling on a road, the iron wheels for track running are stored in the vehicle body, the wheels for road running are grounded, and the wheels run on the track. When running, the iron wheels for track running are configured to project on the track, and are attached to the lower center of the vehicle body and stored at the lower part of the vehicle body, and between the storage position that projects downward and the projecting position that lifts and supports the vehicle body A center jack that can be extended and retracted between, a rotating member that is rotatably attached to the lower part of the center jack, and a lower member that is horizontally slidably attached to the rotating member below the rotating member and has a lower surface. Contact A track mounting method for a track running vehicle (for example, the track working vehicle 1 in the embodiment) configured to include a body moving device having a sliding portion that slides, wherein the track running iron wheel is stored in the vehicle body. In addition, the center jack is reduced to the retracted position, and the vehicle body moving device is driven up by the road traveling wheels while being pulled up above the road traveling wheels. The vehicle body is moved to a position straddling the mounting target track within a range that does not contact a train passing through an adjacent track (for example, the adjacent rail R ′ in the embodiment) laid adjacent to the mounting rail R in the embodiment, and The jack is extended to the overhang position, the slide portion is grounded, the vehicle body is lifted and supported, the road running wheels are set to a non-ground state, and the rotating member is set so that the vehicle body is substantially parallel to the mounting target track. In this state, the position of the rotation center axis of the rotating member is shifted to a side away from the adjacent track with respect to the track center axis of the mounting target track, and the track traveling iron wheel is moved with respect to the mounting target track. When the vehicle is displaced in the lateral direction, the rotating member is slid with respect to the slide portion that is grounded so that the vehicle body slides toward the mounting target track, and the track is moved to a position facing above the mounting target track. The traveling iron wheel is moved, the track traveling iron wheel is projected on the mounting target track, the center jack is reduced to the storage position, and the track traveling iron wheel is placed on the mounting target track.
[0011]
According to the track mounting method of the above configuration, when the track traveling vehicle is mounted on the track to be mounted, the vehicle is positioned at a position where the front end of the vehicle body straddles the track to be mounted within a range that does not contact a train passing through the adjacent track. The vehicle body is moved, and the vehicle body is rotated so that the vehicle body is parallel to the track at that position. In this state, the position of the rotation center axis of the rotating member is shifted to a side farther from the adjacent track than the track center axis, and When the track traveling iron wheel is shifted laterally with respect to the mounting target track, the vehicle body is slid to the mounting target track side by the vehicle body moving device to a position facing above the mounting target track. In the process of placing the track running vehicle on the mounting target track by moving the track running iron wheel, there is no risk that the vehicle will contact the train running on the adjacent track, and the train passing on the adjacent track will be temporarily stopped Eliminate the need to It is possible. Also, without being affected by the interval of trains passing on adjacent tracks, the track-and-land work vehicle placed on the track to be mounted can be removed from the track to be mounted, and placed on the track to be mounted. It is possible to extend the working time of the work by the track-and-rail working vehicle.
[0012]
In the track mounting method having the above configuration, when the track traveling iron wheel is shifted laterally with respect to the mounting target track, the vehicle body is slid toward the mounting target track with respect to the grounded slide portion. If the size of the slide stroke that can be performed is smaller than the lateral displacement between the mounting target track and the track running iron wheel mounted on the track, the center jack is moved down to the retracted position. The road running wheels are grounded, and the sliding portion is slid relative to the rotating member so that the sliding portion moving to the side away from the adjacent track with respect to the rotating member moves closer to the adjacent track side, The center jack is extended to the overhang position to make the road running wheels non-ground, and the vehicle body is slid toward the mounting target track side via a rotating member with respect to the ground slide portion. It may be repeated Ido working.
[0013]
According to the track mounting method having the above-described configuration, the magnitude of the slide stroke of the rotating member toward the mounting target track with respect to the grounded slide portion is determined between the mounting target track and the track traveling iron wheel mounted on the track. If the amount of displacement is smaller than the lateral displacement amount, even if the rotating member is slid with respect to the slide portion, the track traveling iron wheel cannot be positioned facing the mounting target track. In such a case, after the slide portion is once pulled up to ground the road running wheel, the slide portion is slid relative to the rotating member toward the side away from the adjacent track. Then, after the slide portion is brought into contact with the ground again to bring the road running wheel into a non-ground state, the rotating member is again slid with respect to the slide portion toward the mounting target track. By repeating such a sliding operation, it is possible to dispose a track running iron wheel that is laterally displaced from the mounting target track regardless of the magnitude of the positional shift amount, at the position above the mounting target track.

Have been.
[0021]
Next, a description will be given of a vehicle body moving device for mounting the track-and-land work vehicle 1 configured as described above on the mounting rail R. The vehicle body moving device 40 is disposed near the position of the center of gravity of the vehicle in a state where the boom 11 shown in FIG. 1 is stored in the vehicle, and projects downward to a lower part of the vehicle body 3 between the front wheel 7 and the rear wheel 8. Installed. As shown in FIG. 3, the vehicle body moving device 40 is mounted on a lower portion of the center of the vehicle body 3 and is capable of extending and contracting vertically downward. A connecting plate mounted on the lower portion of the center jack 43 and extending horizontally. 44, a rotation mechanism unit 60 attached to a substantially lower portion of the center of the connection plate 44, a rotation member 45 attached to a lower portion of the rotation mechanism unit 60, and a slide for slidingly moving the rotation member 45 in a state where the lower surface is grounded. It has a portion 49 and a plurality of horizontal adjustment jacks 57 attached to the edge of the slide portion 49.
[0022]
The pair of center jacks 43 are disposed at symmetrical positions with respect to the vehicle center axis S of the vehicle extending in the front-rear direction. It can be extended and retracted between. The connection plate 44 is rectangular in plan view, and is fixed to the lower end of the center jack 43 in a state where the connection plate 44 extends in the horizontal direction. The above-described rotation mechanism 60 is sandwiched between a substantially central portion of the connection plate 44 and the rotation member 45. As shown in FIG. 4, the rotation mechanism 60 fits into the lower part of a cylindrical rotary shaft 61 that projects downward from the lower surface of the connection plate 44 to attach the connection plate 44 to the center of rotation of the rotary shaft 61. It has a turntable 63 for rotatably holding the axis T as a center of rotation, and a drive unit 69 for driving the turntable 63 to rotate.
[0023]
The turntable 63 has an annular inner race (not shown) on the inner side and an annular outer race 64 rotatably fitted around the rotation center axis T as a rotation center on the radially outer side of the inner race. The lower end of the rotary shaft 61 is fixed to the center of the shaft. For this reason, the inner race and the connection plate 44 are integrated via the rotating shaft 61. A fixed gear 64a is formed on the outer periphery of the outer race 64, and a projecting portion 55 projecting downward is formed at the lower center of the outer race 64. The lower portion of the projecting portion 55 is fixed to the upper surface of the center of the rotating member 45. It is attached in the state where it was set. For this reason, the outer race 64 and the rotating member 45 are integrated.
[0024]
The drive unit 69 is installed at the upper part of the peripheral edge of the connection plate 44, and is attached to the rotary motor 70 whose shaft 70a extends downward through the connection plate 44 so as to be rotatable, and is fixed to the lower end of the shaft 70a. And a drive gear 71 meshing with the fixed gear 64a of the outer race 64. Therefore, when the drive gear 71 is rotationally driven while the slide portion 49 is grounded, the drive gear 71 revolves while rotating around the fixed gear 64a to rotate the connection plate 44. On the other hand, when the drive gear 71 is rotationally driven while the slide portion 49 is not grounded, the slide portion 49 rotates in a direction opposite to the rotation direction of the drive gear 71. The turntable 63 is configured such that the outer race 64 does not come off from the inner race when the slide portion 49 is in a non-ground state.
[0025]
The rotating member 45 to which the turntable 63 is fixed has a U-shape in a side view, and has a bottom 45a extending in the horizontal direction, a side 45b extending upward from each of the left and right ends of the bottom 45a, and a pair of sides 45b. It is formed to have a horizontally extending flange portion 45c protruding outward from each top.
[0026]
A slide portion 49 that slides relative to the rotating member 45 includes a pair of slide rails 52 extending along the flange portion 45c below the flange portion 45c of the rotating member 45, and a slide cylinder illustrated in FIG. 54. Engaging members 53 fixed to both ends of the flange portion 50c shown in FIG. 3 are engaged with the slide rails 52, and guide the relative sliding movement of the rotating member 45 by the engaging members 53. As shown in FIG. 5, the slide cylinder 54 has one end pivotally connected to the inner surface of the slide rail 52 and the other end pivotally connected to the end of the rotating member 45, and connects the rotating member 45 to the slide rail 52. Slide along. For this reason, when the slide cylinder 54 is extended and contracted while the slide portion 49 shown in FIG. 3 is grounded, the rotating member 45 slides along the slide rail 52 with respect to the slide rail 52, and The vehicle body 3 can be slid in the same direction as the direction in which the slide rail 52 extends through the connected connection plate 44 shown in FIG. When the slide cylinder 54 is extended and contracted while the slide portion 49 shown in FIG. 3 is in a non-ground state, the slide portion 49 is slid with respect to the rotation member 45, and the rotation member 45 is moved relative to the slide rail 52. You can change the position.
[0027]
At the bottom of both ends of the slide rail 52 thus configured, as shown in FIG. 3, a plate-shaped insulating member 56 mounted with these mounted thereon is provided. The details of the operation of the vehicle body moving device 40 will be described later.
[0028]
At each end of the pair of slide rails 52, a horizontal adjustment cylinder 57 configured to be vertically expandable and contractible is fixedly attached. When the horizontal adjustment cylinder 57 is extended and contracted when the slide section 49 is inclined with respect to the horizontal while the slide section 49 is grounded, the slide section 49 is brought into a horizontal state. Can be. As a result, the vehicle body 3 can be made horizontal by the horizontal adjustment cylinder 57.
[0029]
The center jack 43, the horizontal adjustment cylinder 57, and the slide cylinder 54 shown in FIG. 5 of the vehicle body moving device 40 are connected to an operation control device (not shown) for controlling the operation of these cylinders. (Not shown), and is electrically connected to an operating device (not shown), and the operation control device operates these cylinders in response to the operation of the operating device. For this reason, the vehicle body moving device 40 can be remotely controlled by operating the operating device from outside the vehicle.
[0030]
Next, a track mounting method according to the present invention for mounting the track-and-ground work vehicle 1 on the mounting rail R using the above-described vehicle body moving device 40 will be described. First, in the vehicle shown in FIG. 1, the track running iron wheel 25 is stored in the vehicle body 3, and the center jack 43 of the vehicle body moving device 40 is reduced to the storage position, so that the slide portion 49 is moved to the front wheel 7 and the rear wheel 8 The front wheel 7 and the rear wheel 8 are brought into contact with a road surface (not shown) (road running state). Then, as shown in FIG. 6A, the vehicle is traveled on the road to the railroad crossing 80 near the work site by the front wheels 7 and the rear wheels 8 shown in FIG. The vehicle body 3 is moved to a position straddling the mounting rail R within a range A where the front end of the cabin 5) does not contact the train 82 passing through the adjacent rail R 'laid adjacent to the mounting rail R.
[0031]
Then, by operating the above-described operating device (not shown), the rotation motor 70 shown in FIG. 4 is driven so that the slide portion 49 is in the same direction as the direction in which the mounting rail R extends, and is shown in FIG. The slide part 49 is rotated with respect to the rotation member 45. Then, the center jack 43 shown in FIG. 4 is extended and moved to the overhang position, and the slide part 49 is grounded on the road surface of the road crossing part D ′ of the road D crossing the railroad crossing 80, and the front wheel 7 shown in FIG. The rear wheel 8 is lifted off the road at the road crossing D '. In addition, the height of the road surface of the road crossing portion D ′ is formed to be substantially the same as the track surface of the mounting rail R.
[0032]
Then, as shown in FIG. 6B, the operating device is operated to drive the rotary motor 70 shown in FIG. 4 so that the vehicle body 3 shown in FIG. On the other hand, the rotating member 45 is rotated. In a general truck vehicle, the length of the vehicle in the front-rear direction is long. Therefore, when the vehicle body 3 is substantially parallel to the mounting rail R, the position of the rotation center axis T of the rotating member 45 shown in FIG. The track rail center axis U of the mounting rail R is shifted to a side away from the adjacent rail R ′, and the iron wheel 25 for track running is shifted laterally with respect to the mounting rail R. In such a case, as shown in FIG. 7C, the operating device is operated to extend and retract the slide cylinder 54 shown in FIG. 5 so that the vehicle body 3 is slid toward the mounting rail R. The rotating member 45 is slid toward the mounting rail R with respect to the slide portion 49 in the ground state shown in FIG. Here, the magnitude Ls of the slide stroke with which the rotating member 45 shown in FIG. 3 can slide toward the mounting rail R with respect to the sliding portion 49 is determined by the mounting rail R and the track running for mounting on the rail. If the displacement Lr in the horizontal direction with respect to the iron wheel 25 is smaller, the iron wheel 25 cannot be disposed facing the mounting rail R at a position above the mounting rail R.
[0033]
In such a case, as shown in FIG. 3, the operating device is operated to reduce the center jack 43 to the retracted position, pull up the slide portion 49, and lift the slide portion 49 from the road surface of the road crossing portion D '. Thus, the front wheel 7 and the rear wheel 8 shown in FIG. Then, by operating the operating device, as shown in FIG. 3, the rotating member 45 ′ moving to the end on the side of the adjacent rail R ′ of the slide portion 49 separates from the adjacent rail R ′ of the slide portion 49 ( The sliding portion 49 is slid relative to the rotating member 45 so as to move to the upper side in FIG. 3 (the lower side in FIG. 3). Then, the center jack 43 is extended to the overhang position, and the slide portion 49 is brought into contact with the road surface of the road crossing portion D ′ as shown in FIG. 7D, and the front wheel 7 and the rear wheel shown in FIG. The wheel 8 is lifted off the road surface at the road crossing D '. Then, by operating the operating device, the rotating member 45 shown in FIG. 3 is slid toward the mounting rail R with respect to the grounded slide portion 49 (the lower side in FIG. 3). In addition, a series of operations from sliding the slide portion 49 to the mounting rail R side to further sliding the slide portion 49 to the mounting rail R side is hereinafter referred to as “slide operation”.
[0034]
Then, when the iron wheel 25 is opposed to the mounting rail R by the first sliding movement of the sliding portion 49 toward the mounting rail R or the first sliding operation, the track traveling device 20 shown in FIG. The cylinder 27 is extended and the iron wheel holding frame 23 is moved to the above-mentioned iron wheel full extension position, and the iron wheel 25 is extended on the mounting rail R. Then, the center jack 43 shown in FIG. 3 is moved down to the retracted position to bring the iron wheel 25 into contact with the mounting rail R, and the vehicle is mounted on the mounting rail R.
[0035]
If the iron wheel 25 is not arranged above the mounting rail R even after the first sliding operation, the above-described sliding operation is repeated until the iron wheel 25 moves above the mounting rail R.

When the track-and-land work vehicle 1 is mounted on the mounting rail R in this manner, as shown in FIG. 6A, the front end of the driving cabin 5 does not contact the train 82 passing through the adjacent rail R '. After moving the vehicle body 3 within the range A, through a series of operations of the vehicle body moving device 40 described above, the iron wheel 25 shown in FIG. It is mounted on the mounting rail R. For this reason, in the process of mounting the track-and-land work vehicle 1 on the mounting rail R, there is no possibility that the vehicle will contact the train 82 passing through the adjacent rail R ', and the train 82 passing through the adjacent rail R' will be temporarily stopped. This eliminates the need to do so. Also, the track-and-land work vehicle 1 mounted on the mounting rail R can be removed from the mounting rail R without being affected by the interval between the trains 82 passing on the adjacent rail R ′. It is possible to extend the work time of the work by the mounted track-and-ground work vehicle 1. Also, when the iron wheel 25 for track running is displaced laterally with respect to the mounting rail R, the sliding movement of the vehicle body 3 can be performed by operating the slide cylinder 54 by remote control of the operating device. This slide movement can be easily performed.
[0037]
When the iron wheel 25 is not arranged above the mounting rail R by the first sliding movement of the rotating member 45 toward the mounting rail R, the above-described sliding operation is repeated one or more times. Can always be moved to a position facing the mounting rail R.
[0038]
In addition, even when the iron wheel 25 is derailed from the mounting rail R, the vehicle body moving device 40 according to the present invention operates the vehicle body moving device 40 in accordance with the above-described track mounting method so that the derailed iron wheel 25 is re-equipped. It can be returned to the state in which it is in contact with the mounting rail R.
[0039]
Further, in the above-described embodiment, when traveling on the mounting rail R, the iron wheel 25 projects over the mounting rail R and is brought into contact therewith, and the front wheel 7 for road traveling is lifted from the mounting rail R, Although the track-and-work vehicle 1 configured to contact the rear wheel 8 for road traveling with the mounting rail R is shown, the iron-wheel 25 is in contact with the mounting rail R as the track-and-work vehicle. In this case, the front wheel 7 and the rear wheel 8 may be lifted from the mounting rail R, or the front wheel 7 and the rear wheel 8 may be grounded on the mounting rail R.

【The invention's effect】
As described above, according to the track mounting method of the track running vehicle of the present invention, when the track running vehicle is mounted on the track, the track is mounted within a range where the front end of the vehicle body does not contact the train passing through the adjacent track. Move the vehicle body to a position that straddles the target track, and rotate the vehicle body so that the vehicle body is parallel to the track at that position, and in this state, the position of the rotation center axis of the rotating member is closer to the track than the track center axis. When the iron wheel for track running is shifted to the side to be separated and the track running iron wheel is shifted laterally with respect to the mounting target track, the vehicle body is slid to the mounting target track side by the body moving device, and the mounting target track is In the process of placing the track running vehicle on the mounting target track, there is no risk that the vehicle will contact the train running on the adjacent track, and the train running on the adjacent track will be Temporarily suspended It is possible to eliminate the need to. Also, without being affected by the interval of trains passing on adjacent tracks, the track-and-land work vehicle placed on the track to be mounted can be removed from the track to be mounted, and placed on the track to be mounted. It is possible to extend the working time of the work by the track-and-rail working vehicle.
