【発明の属する技術分野】
本発明は、レール間隔調整構造に関し、特に、鉄道分岐器において、脱線防止や車輪走行路確保のために使用されるガードレールと基本レールとの間隔を調整するための構造および軌間整正のためのレール間隔調整構造に関する。
【0002】
【従来の技術】
本発明の理解を容易にするために、鉄道分岐器の概略構成を図1に示す。図1において、1、2は基本レールであり、基本レール1、2の内側にはリードレール3、4が設置されており、基本レール1、2上を左方から走行してきた車両が本線から分岐線に移ろうとする場合、基本レール2上を走行してきた車輪はポイント(図示せず)を切り換えることによってリードレール4に乗り移り、以後左右両車輪は基本レール1とリードレール4上を走行し、クロッシング部においてリードレール4上の車輪はウイングレール6に乗り移り、以後左右両車輪は基本レール1とウイングレール6上を走行し、やがてウイングレール6上の車輪はノーズレール7上を走行し、最終的に両車輪は基本レール1、8上に達して分岐線への乗り換えが完了する。
【0003】
一方、基本レール1、2上を左方から走行してきた車両が本線から分岐線に移らずに本線上をそのまま走行する場合、基本レール1上を走行してきた車輪はポイント(図示せず)を切り換えることによってリードレール3に乗り移り、以後左右両車輪は基本レール2とリードレール3上を走行し、クロッシング部においてリードレール3上の車輪はウイングレール5に乗り移り、以後両車輪は基本レール2とウイングレール5上を走行し、やがてウイングレール5上の車輪はノーズレール7上を走行し、最終的に両車輪は基本レール2、9からなる本線上を走行する。
【0004】
以上のようにして行われる本線から分岐線への乗り換え及び本線上の走行継続において、車輪がクロッシング部を通過する際の車輪の異線への進入を防止したり、ウイングレール5、6およびノーズレール7の側面摩耗を防止する目的でガードレール10、11が設置されている。
【0005】
図10は、図1のA−A矢視部を拡大し、且つレール上に車輪を載置した状態を示す断面図である。図10において、12は左車輪、13は右車輪を示す。図10に示されているように、左車輪12のフランジ部12aはガードレール10の側面に当接しており、右車輪13はノーズレール7とウイングレール6の頭部に当接している。図10に明らかなように、ガードレール10の側面は左車輪12のフランジ部12aと当接しており、ガードレール10の側面は左車輪12との摺接動作で摩耗し、新品のガードレールを設置後、数年でフランジウエー幅14の適正な間隔寸法を保持できなくなるのが一般的である。このフランジウエー幅14が適正な間隔寸法に保持されていないと、車輪の異線への進入やウイングレール5、6およびノーズレール7の側面摩耗を防止するというガードレールの目的を達成することができなくなる。この場合、フランジウエー幅14を適正な間隔寸法に保持するには、摩耗したガードレール10を基本レール1側へ接近させることが必要であるが、図10に示すように、基本レール1とガードレール10との間隔を保持する間隔保持材15が一体のブロックで構成されたものであると、フランジウエー幅14の調整ができず、結局、ガードレールを新品に取り替えざるを得ない。しかしながら、ガードレールの取り替えは、多大な費用と労力を必要とし、コストが上昇する。
【0006】
そこで、上記不都合を解消するためのレール間隔調整機構として、実公昭26−14303号公報には、図11に示すように、基本レール61とガードレール62の間に、挟板63を介して分割間隔材64と65を挿入し、挟板63を脱着することにより基本レール61とガードレール62の間隔を調整する機構66が開示されている(以下、「従来の間隔調整機構1」という)。
【0007】
また、実開昭56−176202号公報には、図12に示すように、基本レール71とガードレール72の間に、中間間隔材73を介して端部間隔材74と75を挿入し、中間間隔材73を脱着することにより基本レール71とガードレール72の間隔を調整する機構76が開示されている(以下、「従来の間隔調整機構2」という)。
【0008】
さらに、実公昭28−802号公報には、図13(a)に示すように、斜めの鋸歯状接合面81を有する一方の部材82と、斜めの鋸歯状接合面83を有する他方の部材84とからなる間隔調整材が開示されている(以下、「従来の間隔調整機構3」という)。
【0009】
【発明が解決しようとする課題】
しかし、従来の間隔調整機構1、2は、それぞれ、挟板63と中間間隔材73を抜き取ることによって間隔を調整する方式であるから、間隔調整代は、その抜き取る材料の厚みに相当する寸法そのものであって、実質的な調整代がない。また、その抜き取り作業において、手先が狭い部分に挟み込まれるという事故が発生することが懸念される。さらに、挟板63や中間間隔材73を保管しなければならないという煩わしさがある。
【0010】
また、従来の間隔調整機構3による実際の間隔調整は、相対する鋸歯状接合面81と83を接合させつつ擦り合わせるようにして一方の部材82と他方の部材84を相互にずらして図13(b)に示す間隔Wを調整し、楕円形の長孔85と86に挿通したボルト(図示せず)で両部材を締結する方式であって、両部材82、84のそれぞれに、長孔85、86と87、88が設けられている関係で、間隔Wを調整するに際し、82と84のいずれか一方の部材を固定し、他方の部材だけを移動させることはできず、上記したように、両方の部材を移動せざるを得ない。そのため、両部材の合計移動量が多くなって、間隔Wの微小量の調整ができないという不都合な点がある(実際に必要とされるWの微小量の数値は、0.5〜1mm程度である)。また、部材の移動量が多いということは、隣接する間隔調整機構の間隙が小さい場合、隣接する間隔調整機構同士がぶつかるということも懸念される。
【0011】
本発明は従来の技術の有するこのような問題点に鑑みてなされたものであって、その目的は、得ようとするレール間隔に確実に調整することが可能なレール間隔調整構造を提供することにある。また、本発明の目的は、安全・簡単で低コストのレール間隔調整構造を提供することにある。
【0012】
【課題を解決するための手段】
上記目的を達成するために本発明は、第一間隔調整部材と第二間隔調整部材よりなる間隔調整部材を採用し、軌間方向(レール長手に直交する方向)の厚みがレール長手方向において変化する第一間隔調整部材に1個のボルトを挿通可能な小孔を軌間方向に形成し、軌間方向の厚みがレール長手方向において変化する第二間隔調整部材に上記ボルトを挿通可能な長孔をレール長手方向に形成し、第一間隔調整部材の小孔と第二間隔調整部材の長孔にボルトを挿通して、第二間隔調整部材を第一間隔調整部材に当接させつつレール長手方向に移動させることにより、2本のレール間隔を簡単に変更することができる。
【0013】
【発明の実施の形態】
すなわち、本発明の要旨は、第一間隔調整部材と第二間隔調整部材を2本のレールの間に挿入してこれらのレール間隔を調整する構造であって、軌間方向の厚みがレール長手方向において変化する第一間隔調整部材に1個のボルトを挿通可能な小孔を軌間方向に形成し、軌間方向の厚みがレール長手方向において変化する第二間隔調整部材に上記ボルトを挿通可能な長孔をレール長手方向に形成し、第一間隔調整部材の小孔と第二間隔調整部材の長孔にボルトを挿通して、第二間隔調整部材を第一間隔調整部材に当接させつつレール長手方向に移動させることにより2本のレール間隔を変更した後、上記ボルトを締め付けることを特徴とするレール間隔調整構造にある。
【0014】
第一間隔調整部材と第二間隔調整部材の接合面をレール長手方向に対して傾斜せしめ、第一間隔調整部材および第二間隔調整部材の軌間方向の合計厚みは、レール長手方向における一方の端部が他方の端部より大きいことが好ましい。
【0015】
2本のレールのうち、一方のレールを基本レールとし、他方のレールをガードレールとすれば、ガードレールの側面が摩耗した場合、第一間隔調整部材と第二間隔調整部材よりなる間隔調整部材により2本のレール間隔を簡単に変更することができるので、ガードレールを取り替えることもなく、フランジウエー幅を適正な間隔寸法に調整することができる。
【0016】
まくらぎ上に固定された床板上にレール締結装置を介して基本レールを締結し、上記床板にガードレールを載置するとともに該床板にレール長手方向に対して斜めの凹溝を形成し、一方の側部には上記凹溝に嵌合可能な凸部を有し且つ他方の側部にはガードレールのレールベース端部に当接可能な凹部を有する座金にボルト挿通用長孔を上記凹溝と平行になるようにレール長手方向に対して斜めに形成し、この座金を用いて基本レールとガードレールの間隔を調整する部材として第一間隔調整部材と第二間隔調整部材よりなる上記間隔調整部材を採用すれば、基本レールとガードレールの間にその間隔調整部材を挿入して基本レールとガードレールの間隔を上記のようにして調整し、上記座金の凸部を床板の凹溝に嵌合して座金の凹部がレールベース端部に当接するまでその座金をレール長手方向に移動させた後、上記ボルト挿通用長孔に挿通したボルトを締め付けることにより、基本レールとガードレールの間隔を簡単に調整することができる。 一方の間隔調整部材の接合面が交互に凹凸部を繰り返してなる鋸歯状面であり、他方の間隔調整部材の接合面が上記凹凸部に噛合可能な鋸歯状面であれば、その鋸歯状面が互いに噛合することによりレール間隔を所定距離に確実に保持することができる。
【0017】
第一間隔調整部材または第二間隔調整部材のいずれか一方に他方の間隔調整部材を載置可能な突出部を設ければ、例えば、第一間隔調整部材に上記突出部を設けることにより、第二間隔調整部材を第一間隔調整部材に当接させつつレール長手方向に移動させるに際して、第二間隔調整部材をその突出部に載置しつつ2本のレール間隔を変更することができるので、第二間隔調整部材が長手方向に移動中に第二間隔調整部材が落下することがない。また、第二間隔調整部材に上記突出部を設ければ、第一間隔調整部材をその突出部に載置しつつ第二間隔調整部材を長手方向に移動させることができるので、その移動中に第一間隔調整部材が落下することがない。
【0018】
ボルト挿通用長孔を形成した座金の両面にそれぞれ、一方の側部には平板の凹溝に嵌合可能な凸部を形成し且つ他方の側部にはレールベース端部に当接可能な凹部を形成すれば、1枚の座金で2種類の座金の機能を果たすことも可能となる。すなわち、その座金の一方の面の凸部を床板の凹溝に嵌合させ、凹部をレールベース端部に当接させたとき、レールベース端面からボルト挿通用長孔中心までの距離の最小値をa、最大値をbとし、その座金の他方の面の凸部を床板の凹溝に嵌合させ、凹部をレールベース端部に当接させたとき、レールベース端面からボルト挿通用長孔中心までの距離の最小値をc、最大値をdとした場合に、a<c≦b<dである関係を満たすように座金の両面に上記凸部と凹部を形成することにより、座金の一方の面の凸部を床板の凹溝に嵌合させて凹部をレールベース端部に当接させつつボルト挿通用長孔にボルトを挿通してその長孔に沿って座金を移動させつつ(b−a)に相当する距離だけ2本のレール間隔を変更することができる。そして、座金を反転させて他方の面の凸部を床板の凹溝に嵌合させて凹部をレールベース端部に当接させつつボルト挿通用長孔に沿って座金を移動させつつ(d−b)に相当する距離だけ2本のレール間隔を変更することができる。以上のように、1枚の座金で(b−a)+(d−b)=(d−a)に相当する距離だけ、2本のレール間隔を変更することができる。以上の操作において、座金の両面の移動操作を連続して効率的に行えるように、cはbを超えない範囲においてbに極力近い数値であることが好ましい。
【0019】
まくらぎ上に固定された床板上に長手方向に配置した2本の基本レールの間隔を調整する手段として両面にそれぞれ上記凸部と凹部を形成した座金を用いれば、基本レール上を車両が高速で走行することにより基本レールに変形(平面方向における波形状の変形)が生じた場合、上記のようにして2本の基本レールの間隔を調整することができるので、脱線等の不都合が生じることはない。
【0020】
【実施例】
以下に本発明の実施例を図面を参照しながら説明する。図2(a)は、本発明の間隔調整部材の側面図であり、16は第一間隔調整部材、17は第二間隔調整部材である。図2(b)は第一間隔調整部材16および第二間隔調整部材17の平面図であり、図2(b)に示すように、第一間隔調整部材16と第二間隔調整部材17の各接合面18、19は、レール長手方向(紙面上において、矢視23または24方向)に対して傾斜している。両接合面18と19ともに、図2(b)に示すように、交互に凹凸部を繰り返してなる鋸歯状面であり、一方の鋸歯状接合面は他方の鋸歯状接合面と噛合可能に形成されている。また、第二間隔調整部材17には第一間隔調整部材16を載置可能な突出部20が設けられている。この突出部に相当するものは、第一間隔調整部材16に設けることもできる。図2(b)に示すように、第一間隔調整部材16には軌間方向に小孔21が穿設されており、第二間隔調整部材17にはレール長手方向に長孔22が穿設されている。第一間隔調整部材16の小孔21から第二間隔調整部材17の長孔22にかけてボルト(図3の番号27)を挿通したまま、長孔22の両端面AまたはBがそのボルトに当接するまで第二間隔調整部材17はレール長手方向に移動することができる。図2(c)は図2(b)の第一間隔調整部材16を右方から見た図であり、図2(d)は図2(b)の第二間隔調整部材17を左方から見た図である。
【0021】
第一間隔調整部材16の小孔21と第二間隔調整部材17の長孔22にボルト(図3の番号27)を挿通して第二間隔調整部材17を第一間隔調整部材16に当接させつつ図2(b)の矢視方向23(レール長手方向)に移動させた場合、第一間隔調整部材16と第二間隔調整部材17とが接合した状態で得られる軌間方向の距離(軌間方向の合計厚み)の最小値は、「d1+d2」である。一方、第二間隔調整部材17を第一間隔調整部材16に当接させつつ図2(b)の矢視方向24(レール長手方向)に移動させた場合、第一間隔調整部材16と第二間隔調整部材17が接合した状態で得られる軌間方向の距離(軌間方向の合計厚み)の最大値は、「d3+d4」である。このように、第一間隔調整部材16と第二間隔調整部材17の軌間方向の合計厚みを変化させることにより、結果としてこれらの間隔調整部材を挿入した2本のレールの間の間隔を調整することができる。
【0022】
図3(a)は、基本レール25とガードレール26の間隔を第一間隔調整部材16と第二間隔調整部材17で調整して、これら2本のレール間隔を変更した後に、ボルト27とナット28で、インサート29、ガードレール26、第一間隔調整部材16、第二間隔調整部材17、基本レール25、インサート30およびスプリングワッシャ31を締結した状態を示す図である。
【0023】
図3(a)に示すように、まくらぎ32上に固定された床板33上にレール締結装置34を介して基本レール25を締結し、床板33上にガードレール26を載置するとともに床板33上に図3(b)に示すようにレール長手方向に対して斜めの凹溝36を形成し、図4(b)に示すように、一方の側部には上記凹溝36に嵌合可能な凸部37を形成し且つ他方の側部にはガードレール26のレールベース26aの端部に当接可能な凹部38が形成された座金39を図3(a)に示すように介在させて、ボルト40とナット41により座金39とガードレール26と床板33を締め付けることができる。42はスプリングワッシャ、43はワッシャ、44はボルト40の挿通孔である。
【0024】
座金39には、図4(a)に示すように、レール長手方向に対して斜めになるようにボルト挿通用長孔45が形成されており、ボルト挿通用長孔45の設置方向は凹溝36(図3(b)参照)の方向と平行である。
【0025】
レール間隔を調整するには、図3(a)のナット41を緩めて、ボルト40を座金39のボルト挿通用長孔45に挿通した状態で長孔45に沿って座金39を移動可能な状態とし、基本レール25とガードレール26の間に挿入した第一間隔調整部材16と第二間隔調整部材17の軌間方向の合計厚みを上記のように調整し、その結果として基本レール25とガードレール26の間隔を調整する。その結果、ガードレール26は基本レール25の方向に図3(a)の矢視Yで示すように移動し、座金39の凹部38とレールベース26aの端部との間にはその移動量に相当する間隙が形成される。そこで、座金39の凸部37を床板33の凹溝36に嵌合した状態で座金39の凹部38がレールベース26aの端部に当接する位置まで座金39をボルト挿通用長孔45に沿って移動させた後、ボルト40とナット41を締め付けることによりガードレール26を床板33上に固定することができる。図5は、以上のようにして、ガードレール26と基本レール25との間隔を第一間隔調整部材16と第二間隔調整部材17で調整した状態を示す平面図である。
【0026】
ところが、レール間隔調整操作に伴ってガードレール26は図3(a)の矢視Yで示すように、基本レール25に向かって移動するので、座金39の凹部38とレールベース26aの端部との間に形成される間隙が大きいと、座金39の凹部38がレールベース26aの端部に当接できないことがある。すなわち、図4(a)の座金39では、レールベース端面46とボルト挿通用長孔中心線47との距離の変化範囲はa1〜a2であり、レール間隔調整によって形成される座金39の凹部38とレールベース26aの端部との間に形成される間隙が大きすぎると、上記距離a2 では不十分な場合がある。このような場合、座金39と、図4(c)に示すように、ボルト挿通用長孔45aと凸部37と凹部38を有し、レールベース端面46とボルト挿通用長孔中心線47との距離の変化範囲がb1〜 b2であって、a1<b1≦a2<b2なる関係を満たすような座金48を併用するか、又は図4(e)に示すように、ボルト挿通用長孔45bと凸部37と凹部38を有し、レールベース端面46とボルト挿通用長孔中心線47との距離の変化範囲がa1〜b2であるような座金49を使用すれば、以上の欠点(座金の凹部38がレールベース26aの端部に当接できないこと)を解消することは可能である。しかし、2種類の座金を使い分けることは、使用しない一方の座金を保管するための管理コストが上昇するという不都合があり、図4(e)のように全長が長い座金は、その座金をボルトで床板上に締結するときの締結力が不安定になるという欠点がある。
【0027】
そこで、図6(a)に示すように、ボルト挿通用長孔45cを形成した座金50において、一方の面の一方の側部には床板の凹溝(図3(b)の番号36)に嵌合可能な凸部51を形成し且つ他方の側部にはレールベース端部(図3(a)の26aの端部)に当接可能な凹部52を形成し、他方の面の一方の側部には床板の凹溝(図3(b)の番号36)に嵌合可能な凸部53を形成し且つ他方の側部にはレールベース端部(図3(a)の26の端部)に当接可能な凹部54を形成し、座金50の一方の面の凸部51を床板の凹溝(図3(b)の番号36)に嵌合し、凹部52をレールベース端部(図3(a)の26aの端部)に当接させたとき、図7(a)に示すように、レールベース端面55からボルト挿通用長孔中心線56までの距離の最小値をa、最大値をbとし、座金の他方の面の凸部53を床板の凹溝(図3(b)の番号36)に嵌合し、凹部54をレールベース端部(図3(a)の26aの端部)に当接させたとき、図7(b)に示すように、レールベース端面55からボルト挿通用長孔中心線56までの距離の最小値をc、最大値をdとした場合に、a<c≦b<dである関係を満たすように座金の両面に上記凸部51、53と凹部52、54を形成すれば、1枚の座金を反転して使用することにより、2種類の座金の機能を1枚の座金で果たすことができ、経済的且つ効率的な締結機構を実現することができる。
【0028】
図8(a)は基本レール25とガードレール26の間隔を第一間隔調整部材16と第二間隔調整部材17で調整し、両面に凸部と凹部を有する座金50を使用して、ボルト40とナット41により座金50とガードレール26と平板35と床板33とを締結する状態を示す側面図、図8(b)は、その締結状態を示す平面図である。
【0029】
図9(a)は、まくらぎ57上に固定された床板58上に長手方向に平行に配置した2本の基本レール59と60の軌間Wを調整する手段として、図6に示す、両面にそれぞれ凸部と凹部を形成した座金50を用いた例を示す側面図、図9(b)はその平面図である。
【0030】

BACKGROUND OF THE INVENTION
The present invention relates to a rail interval adjustment structure, and in particular, in a railroad turnout, a structure for adjusting the interval between a guard rail and a basic rail used for preventing derailment and securing a wheel traveling path, and for adjusting a gap between rails. The present invention relates to a rail interval adjustment structure.
[0002]
[Prior art]
In order to facilitate understanding of the present invention, a schematic configuration of a railway turnout is shown in FIG. In FIG. 1, reference numerals 1 and 2 denote basic rails. Lead rails 3 and 4 are installed inside the basic rails 1 and 2, and a vehicle traveling from the left on the basic rails 1 and 2 is viewed from the main line. When moving to the branch line, the wheel traveling on the basic rail 2 is transferred to the lead rail 4 by switching the point (not shown), and the left and right wheels travel on the basic rail 1 and the lead rail 4 thereafter. In the crossing section, the wheels on the lead rail 4 are transferred to the wing rail 6, and the left and right wheels run on the basic rail 1 and the wing rail 6, and the wheels on the wing rail 6 eventually run on the nose rail 7. Finally, both wheels reach the basic rails 1 and 8 and the transfer to the branch line is completed.
[0003]
On the other hand, when a vehicle traveling from the left on the basic rails 1 and 2 travels on the main line without moving from the main line to the branch line, the wheel traveling on the basic rail 1 points (not shown). The left and right wheels travel on the basic rail 2 and the lead rail 3 after switching, and the wheels on the lead rail 3 are transferred to the wing rail 5 in the crossing section. The vehicle travels on the wing rail 5, and eventually the wheels on the wing rail 5 travel on the nose rail 7, and finally both wheels travel on the main line composed of the basic rails 2 and 9.
[0004]
In the transfer from the main line to the branch line and the continuation of travel on the main line performed as described above, it is possible to prevent the wheel from entering the different line when passing through the crossing section, or to prevent the wing rails 5 and 6 and the nose from entering. Guard rails 10 and 11 are installed for the purpose of preventing side surface wear of the rail 7.
[0005]
FIG. 10 is a cross-sectional view illustrating a state in which the AA arrow portion of FIG. 1 is enlarged and a wheel is placed on the rail. In FIG. 10, 12 indicates a left wheel and 13 indicates a right wheel. As shown in FIG. 10, the flange portion 12 a of the left wheel 12 is in contact with the side surface of the guard rail 10, and the right wheel 13 is in contact with the heads of the nose rail 7 and the wing rail 6. As apparent from FIG. 10, the side surface of the guard rail 10 is in contact with the flange portion 12a of the left wheel 12, and the side surface of the guard rail 10 is worn by sliding operation with the left wheel 12, and after installing a new guard rail, In general, it is not possible to maintain an appropriate gap dimension of the flange width 14 in several years. If the flange way width 14 is not maintained at an appropriate distance, it is possible to achieve the purpose of the guard rail to prevent the wheel from entering another line and the side surfaces of the wing rails 5 and 6 and the nose rail 7 from being worn. Disappear. In this case, in order to keep the flange width 14 at an appropriate distance, it is necessary to bring the worn guard rail 10 closer to the basic rail 1 side. However, as shown in FIG. If the interval holding member 15 that holds the interval is constituted by an integral block, the flange way width 14 cannot be adjusted, and eventually the guard rail must be replaced with a new one. However, replacement of the guardrail requires a great deal of cost and labor, and the cost increases.
[0006]
Therefore, as a rail interval adjusting mechanism for solving the above inconvenience, Japanese Utility Model Publication No. 26-14303 discloses a dividing interval between a basic rail 61 and a guard rail 62 via a sandwich plate 63 as shown in FIG. A mechanism 66 that adjusts the distance between the basic rail 61 and the guard rail 62 by inserting the members 64 and 65 and detaching the clamping plate 63 is disclosed (hereinafter referred to as “conventional distance adjusting mechanism 1”).
[0007]
In Japanese Utility Model Laid-Open No. 56-176202, as shown in FIG. 12, end spacing members 74 and 75 are inserted between a basic rail 71 and a guard rail 72 via an intermediate spacing member 73, and the intermediate spacing is set. A mechanism 76 for adjusting the distance between the basic rail 71 and the guard rail 72 by detaching the material 73 is disclosed (hereinafter referred to as “conventional distance adjusting mechanism 2”).
[0008]
Furthermore, in Japanese Utility Model Publication No. 28-802, as shown in FIG. 13A, one member 82 having an oblique serrated joint surface 81 and the other member 84 having an oblique serrated joint surface 83 are provided. (Hereinafter referred to as “conventional distance adjusting mechanism 3”).
[0009]
[Problems to be solved by the invention]
However, since the conventional distance adjusting mechanisms 1 and 2 are systems in which the distance is adjusted by extracting the sandwich plate 63 and the intermediate distance material 73, the distance adjustment allowance itself is a dimension corresponding to the thickness of the material to be extracted. And there is no substantial adjustment fee. Moreover, in the extraction operation, there is a concern that an accident may occur in which the hand is caught in a narrow portion. Furthermore, there is an inconvenience that the sandwich plate 63 and the intermediate spacing member 73 must be stored.
[0010]
Further, the actual distance adjustment by the conventional distance adjusting mechanism 3 is performed by shifting the one member 82 and the other member 84 from each other so as to rub against each other while joining the sawtooth joining surfaces 81 and 83 facing each other. b) adjusting the distance W shown in FIG. 6B, and fastening both members with bolts (not shown) inserted into the elliptical long holes 85 and 86, respectively. 86, 87, 88 are provided, and when adjusting the interval W, either one of the members 82 and 84 cannot be fixed and only the other member cannot be moved. Both members must be moved. Therefore, there is a disadvantage that the total movement amount of both members increases and the minute amount of the interval W cannot be adjusted (the minute amount of W actually required is about 0.5 to 1 mm). is there). In addition, the fact that the amount of movement of the member is large is also a concern that when the gap between the adjacent interval adjusting mechanisms is small, the adjacent interval adjusting mechanisms collide with each other.
[0011]
The present invention has been made in view of the above-described problems of the prior art, and an object of the present invention is to provide a rail interval adjustment structure capable of reliably adjusting to the desired rail interval. It is in. Another object of the present invention is to provide a safe, simple and low-cost rail spacing adjustment structure.

Then, the washer is reversed, the convex part of the other surface is fitted into the concave groove of the floor plate, and the concave part is brought into contact with the end of the rail base while moving the washer along the bolt insertion slot (d- The distance between the two rails can be changed by a distance corresponding to b). As described above, the distance between the two rails can be changed by a distance corresponding to (b−a) + (d−b) = (d−a) with one washer. In the above operation, it is preferable that c is a numerical value as close as possible to b within a range not exceeding b so that the both-side movement operation of the washer can be performed efficiently.
[0019]
If the washer with the convex and concave portions formed on both sides is used as a means to adjust the distance between the two basic rails arranged in the longitudinal direction on the floor plate fixed on the sleeper, the vehicle will move at high speed on the basic rail. When the basic rail is deformed (waveform deformation in the plane direction) due to traveling at, the distance between the two basic rails can be adjusted as described above, resulting in inconveniences such as derailment. There is no.

Thus, by changing the total thickness of the first gap adjusting member 16 and the second gap adjusting member 17 in the gauge direction, the gap between the two rails into which these gap adjusting members are inserted is adjusted as a result. be able to.
[0022]
In FIG. 3A, the distance between the basic rail 25 and the guard rail 26 is adjusted by the first distance adjusting member 16 and the second distance adjusting member 17 to change the distance between the two rails, and then the bolt 27 and the nut 28 are changed. FIG. 6 is a view showing a state in which the insert 29, the guard rail 26, the first interval adjusting member 16, the second interval adjusting member 17, the basic rail 25, the insert 30 and the spring washer 31 are fastened.
[0023]
As shown in FIG. 3A, the basic rail 25 is fastened on the floor plate 33 fixed on the sleeper 32 via the rail fastening device 34, and the guard rail 26 is placed on the floor plate 33 and the floor plate 33 is placed on the floor plate 33. As shown in FIG. 3 (b), a groove 36 that is oblique to the longitudinal direction of the rail is formed. As shown in FIG. 4 (b), one side can be fitted into the groove 36. A washer 39 having a convex portion 37 and a concave portion 38 formed on the other side and capable of contacting the end of the rail base 26a of the guard rail 26 is interposed as shown in FIG. The washer 39, the guard rail 26, and the floor plate 33 can be tightened by the 40 and the nut 41. 42 is a spring washer, 43 is a washer, and 44 is an insertion hole for the bolt 40.
[0024]
As shown in FIG. 4A, the washer 39 is formed with a bolt insertion long hole 45 so as to be inclined with respect to the rail longitudinal direction, and the installation direction of the bolt insertion long hole 45 is a concave groove. It is parallel to the direction of 36 (see FIG. 3B).
[0025]
In order to adjust the rail interval, the nut 41 of FIG. 3A is loosened, and the washer 39 can be moved along the long hole 45 in a state where the bolt 40 is inserted into the bolt insertion long hole 45 of the washer 39. The total thickness in the gauge direction of the first gap adjusting member 16 and the second gap adjusting member 17 inserted between the basic rail 25 and the guard rail 26 is adjusted as described above. As a result, the basic rail 25 and the guard rail 26 Adjust the interval. As a result, the guard rail 26 moves in the direction of the basic rail 25 as indicated by the arrow Y in FIG. 3A, and corresponds to the amount of movement between the recess 38 of the washer 39 and the end of the rail base 26a. A gap is formed. Therefore, with the convex portion 37 of the washer 39 fitted in the concave groove 36 of the floor plate 33, the washer 39 is moved along the bolt insertion elongated hole 45 until the concave portion 38 of the washer 39 abuts against the end portion of the rail base 26a.

However, since the guard rail 26 moves toward the basic rail 25 as shown by an arrow Y in FIG. 3A in accordance with the rail interval adjustment operation, the gap between the recess 38 of the washer 39 and the end portion of the rail base 26a is changed. If the gap formed between them is large, the recess 38 of the washer 39 may not be able to contact the end of the rail base 26a. That is, in the washer 39 of FIG. 4A, the range of change in the distance between the rail base end face 46 and the bolt insertion long hole center line 47 is a 1 to a 2 . If the gap formed between the recess 38 and the end of the rail base 26a is too large, the distance a 2 may be insufficient. In such a case, as shown in FIG. 4 (c), the washer 39 has a bolt insertion long hole 45a, a convex portion 37, and a concave portion 38, a rail base end face 46, a bolt insertion long hole center line 47, A distance change range of b 1 to b 2 and using a washer 48 that satisfies the relationship of a 1 <b 1 ≦ a 2 <b 2 , or as shown in FIG. has a bolt insertion long hole 45b and the projection 37 and the recess 38, using a washer 49, such as changing the range of the distance between the rail base end surface 46 and the bolt insertion long hole center line 47 is at a 1 ~b 2 By doing so, it is possible to eliminate the above-described drawbacks (the fact that the recess 38 of the washer cannot contact the end portion of the rail base 26a). However, using the two types of washers properly has the disadvantage of increasing the management cost for storing one washer that is not used. For a washer with a long overall length as shown in FIG. There is a drawback that the fastening force when fastening on the floor board becomes unstable.
[0027]
Therefore, as shown in FIG. 6 (a), in the washer 50 in which the bolt insertion long hole 45c is formed, a groove on the floor plate (number 36 in FIG. 3 (b)) is formed on one side of one surface. A convex portion 51 that can be fitted is formed, and a concave portion 52 that can be brought into contact with the end portion of the rail base (the end portion 26a in FIG. 3A) is formed on the other side portion. A convex portion 53 that can be fitted into a concave groove (number 36 in FIG. 3B) is formed on the side portion, and a rail base end portion (the end of 26 in FIG. 3A) is formed on the other side portion. A concave portion 54 that can abut against the groove), a convex portion 51 on one surface of the washer 50 is fitted into a concave groove (number 36 in FIG. 3B), and the concave portion 52 is connected to the end of the rail base. As shown in FIG. 7 (a), the distance from the rail base end face 55 to the bolt insertion long hole center line 56 when abutting against (the end of 26a in FIG. 3 (a)). The minimum value is a, the maximum value is b, the convex portion 53 on the other surface of the washer is fitted into the concave groove (number 36 in FIG. 3B), and the concave portion 54 is the end of the rail base (FIG. 3). 7A, the minimum value of the distance from the rail base end surface 55 to the bolt insertion long hole center line 56 is c, the maximum value, as shown in FIG. 7B. If the above-mentioned convex portions 51 and 53 and concave portions 52 and 54 are formed on both sides of the washer so as to satisfy the relationship of a <c ≦ b <d where By doing so, the functions of two types of washers can be achieved by a single washer, and an economical and efficient fastening mechanism can be realized.
