Description

【０００１】
【発明の属する技術分野】
本発明は例えば鉄道線路及びその周囲の補修作業等に用いられる軌道用作業機に関するものである。
【０００２】
【従来の技術】
従来この種の軌道用作業機として、例えば実開平４−５９５０５号公報や実開平４−７４１０５号公報の如く、ショベル系掘削機構やクレーン機構等が配備される作業機体に地上走行用の履帯やタイヤ等の走行駆動体及び軌条走行用の車輪を備えたものが知られている。
【０００３】
しかして、例えば、ショベル掘削作業、クレーン作業や枕木交換作業時は履帯やタイヤ等の走行駆動体を地上に設置すると共に車輪を地上から浮かせて離して行い、また場所移動等のため軌条上を走行する時は車輪を軌条上に載架すると共に履帯やタイヤ等の走行駆動体を地上から浮かせて離し、この状態で車輪を駆動して軌条走行するように構成されている。
【０００４】
【発明が解決しようとする課題】
しかしながら上記従来構造において、軌条走行用の車輪の駆動構造としては、各車輪毎に別個独立して配置され、車輪の回転軸線と同心上に配置された回転軸に油圧式の駆動モータを直結した構造の四軸駆動構造に構成され、このため四個の回転軸をそれぞれ軸受体により軸受し、駆動モータの回転トルクを回転軸を介して車輪に伝達することになり、それだけ回転軸の軸受構造を回転トルク負荷及び軸受荷重負荷の両要素を加味した構造としなければならず、それだけ軸受構造が複雑化し易いという不都合を有している。
【０００５】
【課題を解決するための手段】
本発明はこのような不都合を解決することを目的とし、作業機体に地上走行用の走行駆動体及び軌条走行用の車輪を備えてなり、上記作業機体の走行方向左右位置に脚機体を配設し、該各脚機体に上記走行駆動体を配設し、上記作業機体の走行方向前後位置に揺動部材を上下揺動自在に配設し、該作業機体と揺動部材との間に上下動用シリンダを架設し、該各揺動部材の先端部にそれぞれ支持軸を配設し、該前後二個の支持軸の両端部に上記車輪を配設し、該揺動部材に駆動モータを配設し、該車輪に該駆動モータにより駆動される伝達部材を一体的に配設してなり、上記車輪は金属製の内輪体と膨出弾性可能な絶縁体と金属製の外輪体とからなり、該絶縁体に挟着凹部を形成すると共に外輪体に挟着凹部に嵌入可能な周鍔部を形成し、該内輪体の外周面一方端部に周鍔部を形成すると共に内輪体の他方端部に締圧部材を固定し、該絶縁体を該周鍔部と該締圧部材とにより挟着することにより絶縁体を膨出させ、この絶縁体の膨出により外輪体の内周面と内輪体の外周面の両面に絶縁体を圧接させると共に該挟着凹部により該周鍔部を挟着してなることを特徴とする軌道用作業機にある。
【０００６】
【発明の実施の形態】

【０００７】
図１乃至図１２の第一形態例において、１は作業機体であって、下部走行機体１ａと上部旋回機体１ｂとからなり、この上部旋回機体１ｂは下部走行機体１ａに旋回軸線１ｃ中心で図示省略の歯車機構からなる旋回操作機構により旋回動作可能に設けられ、この場合上部旋回機体にクレーン機構としての作業機構２が配備されている。尚、クレーン機構に限らずバケット掘削機構やその他の作業機構２が配備されるものである。

【００１１】
１８は広狭調節機構であって、この場合、上記揺動部材５の先端部の車軸筒部５ｂに上記支持軸８・８を軸受１９により回転自在に軸受し、図９又は図１０の如く、各支持軸８にプーリー状の伝達部材２０を嵌挿すると共に上記車輪９及び締圧部材１６を支持軸９の軸線方向に移動自在に嵌挿し、内輪体９ａの外方に位置して支持軸８に押圧部材２１を嵌挿し、複数個の締付ボルト２２を押圧部材２１側から締圧部材１６及び内輪体９ａを貫通して伝達部材２０に螺着し、図９の如く、伝達部材２０と内輪体９ａの内側面との間、又は、図１０の如く、締圧部材１６と押圧部材２１との間に配置される二つ割り状の一対の分割部材２３・２３を形成し、伝達部材２０、内輪体９ａの内側面、締圧部材１６、押圧部材２１、に分割部材２３・２３が嵌入可能な嵌入周溝２４・２５・２６・２７をそれぞれ形成し、これにより伝達部材２０、分割部材２３、車輪９、締圧部材１６及び押圧部材２１を一体化し、支持軸８の端部寄りにストッパーリング２８を嵌着し、これにより上記一体化された伝達部材２０、分割部材２３、車輪９、締圧部材１６及び押圧部材２１の支持軸８からの抜け外れを防ぎ、さらに支持軸８の端面に固定部材２９をボルト３０により取り付けて、一体化された伝達部材２０、分割部材２３、車輪９、締圧部材１６及び押圧部材２１を支持軸８に支持軸８の軸線方向に位置固定して取り付け、二本の軌条Ｗ・Ｗ間の寸法Ｌ₁又はＬ₂により車輪９寸法を変更するように構成している。
【００１２】
３１は車輪駆動機構であって、上記左右一対計四個の揺動部材５の腕部５ｂの支点軸７寄りの側面に取付台３２を取付け、四個の腕部５ｂの内の、三個の腕部５ｂの取付台３２に油圧式の駆動モータ３３を取付けると共に残りの一個の腕部５ｂに油圧式のブレーキ３４を取付け、これにより駆動モータ３３及びブレーキ３４と地上Ｓとの間に離間距離Ｍを確保し、駆動モータ３３及びブレーキ３４と上記伝達部材２０との間に伝動機構３５を介装し、この場合駆動モータ３３及びブレーキ３４の主軸にプーリ状の駆動輪体３６を取付け、駆動輪体３６と伝達部材２０との間にベルト３７を掛回し、駆動モータ３３によりベルト３７を介して伝達部材２０を駆動回転させ、複数個の締付ボルト２２を介して車輪９を回転させると共に油圧ブレーキ３４によりベルト３７を介して伝達部材２０に制動力を付与するように構成している。
【００１３】
この実施の第一形態例は上記構成であるから、例えばクレーン作業時は、図３及び図６の如く、上下動用シリンダ１０のロッドを縮小動作させることにより揺動部材５を支点軸７を中心にして上向き揺動させ、これにより四個の車輪９をそれぞれ上昇位置させることにより走行駆動体４としての履帯を両側二本の軌条Ｗの側方の地上Ｓに載せ、車輪を軌条Ｗから浮上させ、この状態でクレーン作業等を行うことになり、また場所移動等のため軌条Ｗ上を走行する時は、図４及び図７の如く、上下動用シリンダ１０のロッドを伸伸動作させることにより揺動部材５を支点軸７を中心として下向き揺動させ、上記車輪９を下降動作して軌条Ｗ上に載架し、これにより作業機体１を浮上させて走行駆動体４を地上から離し、この状態で車輪９を駆動して軌条走行することになる。
【００１４】
この場合、各揺動部材５・５の先端部にそれぞれ支持軸８・８を配設し、前後二個の支持軸８・８の両端部に車輪９を配設し、揺動部材５・５に駆動モータ３３を配設し、伝達部材２０、分割部材２３、車輪９、締圧部材１６及び押圧部材２１一体化し、固定部材２９により、車輪９と一体化された伝達部材２０を支持軸８に支持軸８の軸線方向に位置固定して取り付け、この車輪９と一体化された伝達部材２０を駆動モータ３３により回転させる構造としているから、各車輪毎に別個独立して配置され、車輪の回転軸線と同心上に配置された回転軸に油圧式の駆動モータを直結した従来構造としての四軸駆動構造に対し、二軸構造となって、車輪９の軸受構造を簡素化することができ、しかも駆動モータ３３の回転トルクをその回転軸としての支持軸８・８を介さずに車輪９に伝達することができ、支持軸８・８の軸受構造を回転トルク負荷をそれほど考慮せずに軸受荷重負荷の要素のみを加味した構造とすることができ、それだけ支持軸８・８の軸受構造を簡素化することができると共に保守保全の作業性を高めることができる。
【００１５】
又、この場合、上記車輪９は金属製の内輪体９ａとＭＣナイロン樹脂材等の膨出弾性可能な絶縁体９ｂ・９ｃと金属製の外輪体９ｄとからなり、この内輪体９ａの外周面一方端部としての内方端部に周鍔部１１を形成し、一方の絶縁体９ｂの内方端部に周鍔部１１に嵌合する段差部１２を形成し、かつ他方の絶縁体９ｃに段差部１３を形成し、この段差部１３と一方の絶縁体９ｂとにより形成される挟着凹部１４を形成し、外輪体９ｄに挟着凹部１４に嵌入可能な周鍔部１５を形成し、内輪体９ａの他方端部の外側面に締圧部材１６をボルト１７により固定し、これにより絶縁体９ｂ・９ｃを周鍔部１１と締圧部材１６とにより挟着し、この挟着により９ｂ・９ｃを膨出させ、この膨出により外輪体９ｄの内周面と内輪体９ａの外周面の両面に絶縁体９ｂ・９ｃを圧接させると共に段差部１３と一方の絶縁体９ｂとにより形成される挟着凹部１４により周鍔部１５を挟着して構成しているから、内輪体９ａと外輪体９ｄとを絶縁体９ｂ・９ｃにより電気的に絶縁することは勿論のこと、内輪体９ａと外輪体９ｄとの結合を確実に行うことができる。
【００１６】
さらに、この場合外輪体９ｄの内周面に周溝９ｅを形成し、内輪体９ａに押圧ボルト９ｆを螺着し、押圧ボルト９ｆにより絶縁体９ｂの内周面を押圧し、押圧により絶縁体９ｂの外周面を膨出させて周溝９ｅ内に没入させるように構成しているから、絶縁体９ｂの支持軸８の軸線方向の抜けを防ぐことができ、一層内輪体９ａと外輪体９ｄとの結合強度を高めることができる。
【００１７】
図１３の第二形態例は第一形態例に非絶縁構造の車輪を適用したものであり、この場合、金属製の車輪９を支持軸８に嵌挿すると共にボルト３０により車輪９を支持軸８に支持軸８の軸線方向に位置固定し、この車輪９に一体的に上記同様な駆動モータにより駆動される伝達部材２０を形成して構成したものである。
【００１８】
この第二形態例にあっても、上記第一形態例と同様に、従来構造としての四軸駆動構造に対し、二軸構造となって、車輪９の軸受構造を簡素化することができ、しかも駆動モータ３３の回転トルクをその回転軸としての支持軸８・８を介さずに車輪９に伝達することができ、支持軸８・８の軸受構造を回転トルク負荷をそれほど考慮せずに軸受荷重負荷の要素のみを加味した構造とすることができ、それだけ支持軸８・８の軸受構造を簡素化することができる。
【００１９】
尚、本発明は上記実施の形態例に限られるものではなく、例えば上記実施の形態例では走行駆動体４として履帯を用いてクローラ式作業機体としているが、履帯に代えて、左右二個宛計四個又は複数個のタイヤを脚機体３・３に配設してタイヤ式作業機体とした構造とすることもあり、又、伝達部材２０構造及び伝達部材２０と車輪９との一体化構造等は適宜変更して設計される。
【００２０】
