Description

本発明は、鉄道車両が脱線した場合でも、車両が軌道から大きく逸走しないように本線レールに沿って配置される車輪逸走防止装置に関する。 The present invention relates to a wheel runaway prevention device that is disposed along a main rail so that the vehicle does not run away from the track even when the railcar derails.

従来、図２１(a) に示すように、バラスト２０３を敷いてまくらぎ２０４を軌道に配設する場合、軌道沈下を防止するために、最も荷重のかかる本線レール２０１の直下付近のバラスト２０２を密にし、本線レール２０１の直下以外のバラスト２０３は比較的粗な状態にしている。しかし、本線レール２０１を介して受ける垂直方向の大荷重によって、図２１(b) に示すように、レール直下付近のバラスト２０３が時間の経過と共に徐々に粗の状態になろうとするので、本線レール２０１の真下付近のバラスト２０３は、所定の期間等で図示しないタイタンパーやマルチプルタイタンパー等（以下、これらを総称して「突き固め機」という）で密に突き固めて充填密度が粗にならないようにしている。 Conventionally, as shown in FIG. 21 (a), when a sleeper 204 is disposed on a track with a ballast 203, the ballast 202 near the most loaded main rail 201 is used to prevent the track from sinking. The ballasts 203 other than those directly below the main rail 201 are relatively coarse. However, due to a large vertical load received via the main rail 201, as shown in FIG. 21 (b), the ballast 203 near the rail tends to gradually become rough with time. The ballast 203 just below 201 is closely packed with a tie tamper, multiple tie tamper (not shown) or the like (hereinafter collectively referred to as a “compacting machine”) for a predetermined period or the like so that the packing density does not become rough. I am doing so.

また、図２２(a),(b) に示すように、曲線軌道などを列車が走行した場合に、車輪が本線レール２０１から外れても、脱線した車両が軌道外側に大きく逸走するのを防いで脱線の被害を最小限にする目的で、安全レール２０５を本線レール２０１に沿って設ける場合がある。この安全レール２０５は、本線レール２０１の軌道内側に設ける場合や、落石および降雪の多い箇所、あるいは特に必要な箇所では、本線レール２０１の外側に設ける場合がある。 Further, as shown in FIGS. 22 (a) and 22 (b), when a train travels on a curved track or the like, even if the wheel is detached from the main rail 201, the derailed vehicle is prevented from greatly running outside the track. In some cases, the safety rail 205 is provided along the main rail 201 for the purpose of minimizing the damage caused by the derailment. The safety rail 205 may be provided inside the track of the main rail 201, or may be provided outside the main rail 201 at a location where a lot of falling rocks and snow fall, or at a particularly necessary location.

さらに、図２３に示すように、上記本線レール２０１には、曲線軌道等の場合、車輪が本線レール２０１から外れないようにガードするガード部材２０６を本線レール２０１と平行に軌間内に配置することがある。 Further, as shown in FIG. 23, in the case of a curved track or the like, a guard member 206 that guards a wheel from being detached from the main rail 201 is arranged in the rail in parallel with the main rail 201 in the main rail 201. There is.

一方、図２３に示す斜線部分が上記突き固め機による作業範囲であり、突き固め機によるバラスト２０２の突き固め作業は、本線レール２０１の近傍において本線レール２０１の真下付近を突き固めるように行う必要がある。しかし、この作業範囲には上記ガード部材２０６や安全レール２０５が存在するため、突き固め機による作業前には、これらの構造物を斜線部分以外の場所へ一時的に撤去させる必要がある。そして、一時的に撤去させた構造物は、作業終了後には元に戻さなければならない。 On the other hand, the hatched portion shown in FIG. 23 is the work range by the tamping machine, and the tamping work of the ballast 202 by the tamping machine needs to be performed in the vicinity of the main rail 201 near the main rail 201. There is. However, since the guard member 206 and the safety rail 205 exist in this work range, it is necessary to temporarily remove these structures to a place other than the shaded part before the work by the tamping machine. And the structure removed temporarily must be returned to the original after the work is completed.

しかし、従来のガード部材２０６は、ボルトとナットの組み合わせを多数用いた締結構造であるため、ガード部材２０６の脱着に非常に手間がかかり煩雑である。また、本線レール２０１から離れた場所まで重量物であるガード部材２０６を人手で移動させる作業は、非常に時間と労力を要する作業となる。 However, since the conventional guard member 206 has a fastening structure using many combinations of bolts and nuts, it is very troublesome to attach and detach the guard member 206. Moreover, the operation | work which moves the guard member 206 which is a heavy article to the place away from the main rail 201 by hand is a work which requires time and labor very much.

この点は、上記安全レール２０５も同様であり、突き固め機による作業時に作業の障害になるので、重量物である安全レール２０５を作業に支障をきたさないように本線レール２０１から離れた場所まで人手によって移動させるには、非常に時間と労力とを要する作業が必要となる。 This also applies to the safety rail 205 described above, which is an obstacle to work when working with a tamping machine. Therefore, the safety rail 205, which is a heavy object, can be moved away from the main rail 201 so as not to interfere with the work. In order to move it manually, work which requires time and labor is required.

また、本線レール２０１は、列車の快適な乗り心地が得られるように、所定期間毎（例えば、１年に１〜２回程度）に保守作業が行われている。この保守作業は、走行時の車両の振動の大小や揺れの方向などのデータで客観的に評価し、基準値を超えた本線レール２０１は、その本線レール２０１上をレール削正車で走行しながら所定形状に本線レール２０１を削るレール削正作業が行われる。 Further, maintenance work is performed on the main rail 201 every predetermined period (for example, about once or twice a year) so that a comfortable ride of the train can be obtained. This maintenance work is objectively evaluated based on data such as the magnitude of vibration of the vehicle and the direction of shaking during travel, and the main rail 201 exceeding the reference value travels on the main rail 201 with a rail grinder. However, the rail correction work for cutting the main rail 201 into a predetermined shape is performed.

そして、このレール削正作業時も、本線レール２０１に沿って設けられたガード部材２０６や安全レール２０５が作業の障害になるので、重量物であるそれらガード部材２０６や安全レール２０５を本線レール２０１から離れた場所まで人手によって移動させる必要があるが、その作業は非常に時間と労力を要する。 Even during this rail correction work, the guard member 206 and the safety rail 205 provided along the main rail 201 are obstacles to the work. Although it is necessary to move it manually to a place away from the site, the work is very time consuming and labor intensive.

なお、この種の従来技術として、本線レール間に傾斜したガードレールを本線レールに沿って設け、車両が脱線した場合でも内側の車輪をこのガードレールで止めて、車両が軌道から大きく逸脱しないようにしようとするものがある（特許文献１参照）。 As this type of conventional technology, guard rails that are inclined between the main rails are provided along the main rails, and even if the vehicle derails, the inner wheels are stopped by this guard rail so that the vehicle does not deviate significantly from the track. (See Patent Document 1).

ところで、近年の鉄道車両には種々の機能を備えさせるための構成が設けられており、それらの多くが床下に配置されている。そして、そのような構成は、車両の床面高さを変更させることは駅ホームの高さとの間に段差を生じるため困難であり、多くの構成が車両下部に設けられている。 By the way, recent railway vehicles are provided with a configuration for providing various functions, and many of them are arranged under the floor. In such a configuration, it is difficult to change the height of the floor surface of the vehicle because a step is generated between the height of the station platform, and many configurations are provided in the lower portion of the vehicle.

例えば、近年の高速車両では、高速走行状態からの安定した停止ができるように電子油圧制御ブレーキ（Electronically Controlled Brake System）を備えさせる場合があり、この電子油圧制御ブレーキのディスクは、車両下部から下向きに突出して設けられており、車輪下端と約３０ｍｍ以上の差となる位置まで突出して設けられている。 For example, in recent high-speed vehicles, there is a case where an electronically controlled brake system (Electronically Controlled Brake System) is provided so that the vehicle can be stably stopped from a high-speed driving state. And protrudes to a position that is about 30 mm or more different from the lower end of the wheel.

そのため、このように車両下部から下向きに大きく突出した構成がある車両が脱線した場合、上記特許文献１の技術では、その突出した構成がガードレールに接触して傷つくおそれがある。 Therefore, when a vehicle having a configuration that protrudes downward from the lower part of the vehicle in this way derails, the technology disclosed in Patent Document 1 may damage the protruding configuration in contact with the guard rail.

そこで、本発明は、車両下部から下向きに突出する構成を具備した車両が本線レールから脱線した場合でも、車両下部から下向きに突出する構成を傷付けることなく車両が軌道から大きく逸走するのを防止できる車輪逸走防止装置を提供することを目的とする。 Therefore, the present invention can prevent the vehicle from greatly running off the track without damaging the configuration protruding downward from the lower part of the vehicle even when the vehicle having the configuration protruding downward from the lower part of the vehicle derails from the main rail. It aims at providing a wheel runaway prevention device.

上記目的を達成するために、本発明は、車両下部から下向きに突出する構成を具備した車両が本線レールから脱線しても軌道外方に逸走しないように、該本線レールに沿ってまくらぎ又はスラブ軌道に配置する車輪逸走防止装置であって、前記本線レール間の中央部に、前記まくらぎ又はスラブ軌道に固定される固定部と、前記本線レールと平行に配置される逸走防止部とを備え、前記固定部は、前記車両の脱線時に該車両の下部に具備された構成と所定の隙間を有する高さに形成され、前記逸走防止部は、前記車両の脱線時に該車両の下部に具備された構成と所定の隙間を有する高さに形成された車輪受面を具備している。この明細書及び特許請求の範囲の書類中における「車両下部から下向きに突出する構成」は、上記電子油圧制御ブレーキのディスク等をいう。これにより、車両が脱線したとしても、その車両下部から下方に突出する構成を傷付けることなく、その構成との間に所定の隙間を有した状態で車輪を本線レール間の中央部に設けた逸走防止部の車輪受面で受けて、車両が軌道から大きく逸走するのを防止することができる。 In order to achieve the above object, the present invention provides a sleeper or a sleeper along the main rail so that a vehicle having a configuration protruding downward from the lower portion of the vehicle does not escape from the track even if the vehicle derails from the main rail. A wheel runaway prevention device disposed on a slab track, wherein a fixed portion fixed to the sleeper or slab track at a central portion between the main rails, and a runaway prevention unit disposed in parallel with the main rails. The fixing portion is formed at a height having a predetermined gap with a configuration provided at a lower portion of the vehicle when the vehicle is derailed, and the escape prevention portion is provided at a lower portion of the vehicle when the vehicle is derailed. And a wheel receiving surface formed at a height having a predetermined gap. The “configuration projecting downward from the lower part of the vehicle” in the specification and claims refers to the disc of the electrohydraulic control brake. As a result, even if the vehicle derails, the wheel running at the center between the main rails with a predetermined gap between the configuration and the configuration that protrudes downward from the lower portion of the vehicle without damaging the configuration. It can be received by the wheel receiving surface of the prevention unit, and the vehicle can be prevented from greatly escaping from the track.

また、前記車輪受面は、前記まくらぎ又はスラブ軌道から所定高さの垂直面に形成されていてもよい。このようにすれば、脱線して回転している車輪の内側を垂直面で安定して受けて、安定した逸走防止を図ることができる。 The wheel receiving surface may be formed on a vertical surface having a predetermined height from the sleeper or slab track. In this way, it is possible to stably receive the inner side of the derailed and rotating wheel on the vertical plane and prevent stable escape.

さらに、前記逸走防止部は、前記固定部の両側部に前記車輪受面を具備した所定長さのガード部材を有し、前記固定部は、前記ガード部材を該固定部の所定位置に配置する配置部を具備していてもよい。このようにすれば、所定長さのガード部材を固定部の配置部に配置すれは逸走防止部を形成することができるので、各構成の取扱いが容易な逸走防止装置を構成することができる。 Further, the escape prevention part has a guard member having a predetermined length provided with the wheel receiving surface on both sides of the fixing part, and the fixing part arranges the guard member at a predetermined position of the fixing part. You may have the arrangement | positioning part. In this way, if the guard member having a predetermined length is arranged in the arrangement part of the fixed part, the escape prevention part can be formed, so that an escape prevention apparatus that can easily handle each component can be configured.

また、前記固定部は、前記配置部に配置したガード部材の位置を決める位置決め部を有し、該位置決め部は、前記固定部に固定した水平方向に傾斜する傾斜面と、前記配置部に固定したガード部材が当接する当接面と、前記傾斜面とガード部材との間に挿入して該ガード部材を前記当接面に向けて水平方向に押圧する楔部材とを具備していてもよい。このようにすれば、固定部の傾斜面と配置部の当接面に当接したガード部材との間に楔部材を挿入し、この楔部材の楔作用によってガード部材を当接面に押圧して水平方向の位置決めを確実に行うことができる。 The fixing portion includes a positioning portion that determines a position of the guard member arranged in the arrangement portion, and the positioning portion is fixed to the arrangement portion and an inclined surface inclined in a horizontal direction fixed to the fixing portion. And a wedge member that is inserted between the inclined surface and the guard member and presses the guard member in the horizontal direction toward the contact surface. . According to this configuration, the wedge member is inserted between the inclined surface of the fixed portion and the guard member that is in contact with the contact surface of the arrangement portion, and the guard member is pressed against the contact surface by the wedge action of the wedge member. Thus, horizontal positioning can be performed reliably.

さらに、前記固定部を、前記まくらぎ上又は前記スラブ軌道の本線レール固定部上に設けて前記ガード部材の長手方向に位置する固定部間を空間としてもよい。このようにすれば、まくらぎ又はスラブ軌道に本線レールを固定している線上にのみ車輪逸走防止装置の固定部が配置されるので、ガード部材の固定部間を空間にしてバラストの保守等が容易に行えるようにできる。 Further, the fixing portion may be provided on the sleeper or on the main rail fixing portion of the slab track, and a space between the fixing portions positioned in the longitudinal direction of the guard member may be used as a space. In this way, since the fixed part of the wheel runaway prevention device is arranged only on the line that fixes the main rail to the sleeper or slab track, maintenance of the ballast can be performed with a space between the fixed parts of the guard member. It can be done easily.

また、前記所定長さのガード部材の連結部に、該ガード部材の端部をまくらぎに向けて押圧する押え部材を設け、該押え部材とガード部材の端分との間に、該ガード部材の軸方向変位を吸収する変位吸収部を具備させてもよい。このようにすれば、ガード部材が温度変化の影響によって軸方向に伸縮したとしても、その端部位置の変位を変位吸収部で吸収してガード部材の端部が構造物に当接することなどを防止できる。 In addition, a pressing member that presses the end of the guard member toward the sleeper is provided at the connecting portion of the guard member having the predetermined length, and the guard member is interposed between the pressing member and the end of the guard member. You may provide the displacement absorption part which absorbs axial displacement of these. In this way, even if the guard member expands and contracts in the axial direction due to the influence of temperature change, the displacement of the end position is absorbed by the displacement absorbing portion, and the end of the guard member abuts against the structure. Can be prevented.

さらに、前記固定部は、前記まくらぎの上面にガード支持材を配置し、該ガード支持材とガード部材とに挿通させた固定具で該ガード部材をまくらぎに固定する構造となっていてもよい。このようにすれば、ガード部材をまくらぎに固定する作業を、ガード部材とガード支持材とに挿通させた固定具で効率良く行うことができる。 Further, the fixing portion may have a structure in which a guard support member is disposed on an upper surface of the sleeper, and the guard member is fixed to the sleeper with a fixture inserted through the guard support member and the guard member. . If it does in this way, the operation | work which fixes a guard member to a sleeper can be efficiently performed with the fixing tool penetrated by the guard member and the guard support material.

また、前記ガード部材は、前記固定部の両側部に配置する車輪当接部材と、該車輪当接部材間を連結する剛性部材とを具備していてもよい。このようにすれば、ガード部材全体の剛性を高めることができる。 Moreover, the said guard member may comprise the wheel contact member arrange | positioned at the both sides of the said fixing | fixed part, and the rigid member which connects between this wheel contact member. If it does in this way, the rigidity of the whole guard member can be raised.

本発明は、以上説明したような手段により、本線レールから脱線した車両の下部から下向きに突出する構成を傷付けることなく、該車両が軌道から大きく逸走するのを防止することが可能となる。 According to the present invention, it is possible to prevent the vehicle from greatly deviating from the track without damaging the configuration projecting downward from the lower portion of the vehicle derailed from the main rail by means as described above.

In the following embodiments, a wheel runaway prevention device provided at the center of a sleeper arranged in the width direction of the track will be described as an example.

図１，２に示すように、この実施の形態の車輪逸走防止装置１は、本線レール３が固定金具４によって固定されたまくらぎ２の中央部に固定される固定部５と、この固定部５の両側部で本線レール３に沿って平行に逸走防止部６とが備えられている。上記固定部５は、まくらぎ２の幅方向中央部に固定される固定部材７と、この固定部材７の両側部で上記逸走防止部６の車輪受面８となって車輪の逸走を防止するガード部材９を配置する配置部１０とを具備している。この実施の形態のガード部材９は、Ｈ型断面の形鋼が用いられ、ウエブ部９ａの高い形鋼を横向きにした状態で本線レール３に沿って平行に固定することにより、このガード部材９のフランジ部９ｂの外側面が車輪受面８となるようにしている。上記ガード部材９は、製造上及び搬送上の制限があるので、それらに適した長さで、まくらぎ２の配置ピッチに応じた長さの物が連続するように配置されている。 As shown in FIGS. 1 and 2, the wheel runaway prevention device 1 according to this embodiment includes a fixed portion 5 that is fixed to a center portion of a sleeper 2 in which a main rail 3 is fixed by a fixing bracket 4, and the fixed portion. A runaway prevention unit 6 is provided in parallel with the main rail 3 on both side portions of 5. The fixing part 5 serves as a wheel receiving surface 8 of the escape prevention part 6 on both sides of the fixing member 7 fixed to the center part in the width direction of the sleeper 2 and prevents escape of the wheel. And an arrangement portion 10 on which the guard member 9 is arranged. The guard member 9 of this embodiment is made of a steel having an H-shaped cross section, and the guard member 9 is fixed in parallel along the main rail 3 in a state in which the steel having a high web portion 9a is turned sideways. The outer surface of the flange portion 9b is the wheel receiving surface 8. Since the guard member 9 is restricted in terms of manufacturing and conveyance, the guard member 9 has a length suitable for the guard member 9 and is arranged such that a length corresponding to the arrangement pitch of the sleepers 2 is continuous.

図１では、図の最下部に示すまくらぎ２から３本目のまくらぎ２までが一体のガード部材９となっている。この３本目のまくらぎ２でガード部材９が分割されており、図示する下側のガード部材９の端部と上側のガード部材９の端部とが、押え部材１１を固定ボルト１２でまくらぎ２に固定することによって固定されている。この部分が、ガード部材分割部であり、詳細は後述する。また、図１に示す最下部のまくらぎ２の部分では、ガード部材９の端部が押え部材１１を固定ボルト１２でまくらぎ２に固定することによって固定されている。さらに、図示する最下部から２本目と４本目のまくらぎ２の部分では、ワッシャ１３を介して固定ボルト１４によってガード部材９がまくらぎ２に固定されている。この部分の詳細も、後述する。 In FIG. 1, the sleeper 2 to the third sleeper 2 shown in the lowermost part of the drawing constitute an integral guard member 9. The guard member 9 is divided by the third sleeper 2, and the end of the lower guard member 9 and the end of the upper guard member 9 shown in FIG. It is fixed by fixing to 2. This portion is a guard member dividing portion, and details will be described later. 1, the end of the guard member 9 is fixed by fixing the presser member 11 to the sleeper 2 with fixing bolts 12. In the lowermost sleeper 2 shown in FIG.

また、上記配置部１０には、上記ガード部材９をまくらぎ２に固定するための貫通長穴２４が設けられている。さらに、固定部材７の下面は、中央部に上記まくらぎ２の上面形状に沿うような中央平面部２５が形成され、この中央平面部２５から両側部に向けて上向き傾斜の斜面部２６に形成されている。 Further, the arrangement portion 10 is provided with a through long hole 24 for fixing the guard member 9 to the sleeper 2. Further, the lower surface of the fixing member 7 is formed with a central flat portion 25 that follows the shape of the upper surface of the sleeper 2 at the central portion, and is formed on a slope portion 26 that is inclined upward from the central flat portion 25 toward both sides. Has been.

図４に示すように、上記楔部材３０は、片面が上記支持壁１６の傾斜面１８と同一角度の傾斜面３１に形され、他面が上記ガード部材９と接する平面３２に形成された楔部３３と、傾斜面３１の広がる側に形成された取付フランジ３４とを有している。この取付フランジ３４には、楔部材３０を上記位置決め部２３に向けて押込む取付ボルト３５（図１，２）を挿通させるボルト穴３６が設けられている。 As shown in FIG. 4, the wedge member 30 has one surface formed on an inclined surface 31 having the same angle as the inclined surface 18 of the support wall 16 and the other surface formed on a flat surface 32 in contact with the guard member 9. It has the part 33 and the attachment flange 34 formed in the side which the inclined surface 31 spreads. The mounting flange 34 is provided with a bolt hole 36 through which a mounting bolt 35 (FIGS. 1 and 2) for pushing the wedge member 30 toward the positioning portion 23 is inserted.

そして、図５(a),(b) に示すように、上記固定部材７は、まくらぎ２との間に防振ゴム４３（図２）が挟まれた状態で上記固定穴１５に固定ボルト２７が挿通されて、まくらぎ２に設けられたネジ穴３７に螺合されて固定される。図５(a),(b) は、図１に示すガード部材９の分割部（継目構造）を示しており、この部分では、図６に示すように、固定部材７に設けられた配置部１０の上部にガード部材９の端部がそれぞれ配置され、両ガード部材９のウエブ部９ａの端部を配置部１０に向けて押圧する押え部材１１によって配置部１０に固定されている。 5 (a) and 5 (b), the fixing member 7 is fixed to the fixing hole 15 with the anti-vibration rubber 43 (FIG. 2) sandwiched between the fixing member 7 and the sleeper 2. 27 is inserted and screwed into a screw hole 37 provided in the sleeper 2 and fixed. FIGS. 5 (a) and 5 (b) show a divided portion (seam structure) of the guard member 9 shown in FIG. 1, and in this portion, as shown in FIG. The end portions of the guard members 9 are respectively disposed on the upper portion of the guard member 9, and are fixed to the placement portion 10 by pressing members 11 that press the end portions of the web portions 9 a of both guard members 9 toward the placement portion 10.

この押え部材１１は、ガード部材９のウエブ部９ａの端部を押える押え部３８と、この押え部３８がウエブ部９ａに接した状態で、固定部材７の斜面部２６の上面に接する脚部３９を有する略Ｔ字状に形成されている。この脚部３９は、ガード部材９との間にこのガード部材９の熱膨張／収縮（温度変化）分の変位を吸収することができる間隔Ｕが形成される大きさとなっている。この間隔Ｕが変位吸収部であり、この間隔Ｕでガード部材９の端部が押え部材１１（構造物）に当接して跳ね上がるのを防止している。この脚部３９の中央部に、固定ボルト１２が貫通する固定穴４０が設けられている。この押え部材１１の固定穴４０に固定ボルト１２を挿通し、この固定ボルト１２をまくらぎ２のネジ穴４１に螺合することによってガード部材９が固定部材７に固定されている。 The presser member 11 includes a presser part 38 that presses the end of the web part 9a of the guard member 9, and a leg part that touches the upper surface of the slope part 26 of the fixing member 7 in a state where the presser part 38 is in contact with the web part 9a. 39 is formed in a substantially T-shape. The leg portion 39 is sized so that a gap U can be formed between the leg member 39 and the guard member 9 so as to absorb a displacement corresponding to thermal expansion / contraction (temperature change) of the guard member 9. This interval U is a displacement absorbing portion, and at this interval U, the end of the guard member 9 is prevented from coming into contact with the pressing member 11 (structure) and jumping up. A fixing hole 40 through which the fixing bolt 12 passes is provided at the center of the leg portion 39. The guard bolt 9 is fixed to the fixing member 7 by inserting the fixing bolt 12 into the fixing hole 40 of the pressing member 11 and screwing the fixing bolt 12 into the screw hole 41 of the sleeper 2.

そして、図５(a),(b) に示すように、このようにガード部材９を固定した状態で、支持壁１６の傾斜面１８とガード部材９のフランジ部９ｂとの間に楔部材３０が挿入され、この楔部材３０の取付フランジ３４と上記取付壁１７との間にスペーサ４５を配置した状態で、取付フランジ３４に設けられたボルト穴３６と取付壁１７に設けられたボルト穴１９とに取付ボルト３５が挿通される。その後、取付フランジ３４の外側からナット４２を取付ボルト３５にねじ込むことにより、楔部材３０の楔部３３が分割部におけるガード部材９の両端部を外向きに押圧して、上記配置部１０の当接面２２にガード部材９のフランジ部内面に密着させる。この時、上記したように取付フランジ３４と取付壁１７との間にスペーサ４５を配置しているので、楔部材３０によるガード部材９の押圧はスペーサ４５の密着によって止まり、配置部１０に配置されたガード部材９が配置部１０の当接面２２に向けて強固に押圧されることなく、ほぼ密着した状態で固定される。このようにすることにより、ガード部材９が温度変化の影響によって軸方向に伸縮したとしても、その端部位置の伸縮（変位）を上記押え部材１１の脚部３９とガード部材９の端部との間隔Ｕの範囲で許容して吸収し、ガード部材９の端部が押え部材１１（構造物）に当接することを防止している。 5 (a) and 5 (b), the wedge member 30 is interposed between the inclined surface 18 of the support wall 16 and the flange portion 9b of the guard member 9 with the guard member 9 fixed in this manner. Is inserted, and the bolt hole 36 provided in the mounting wall 17 and the bolt hole 19 provided in the mounting wall 17 are provided with the spacer 45 disposed between the mounting flange 34 of the wedge member 30 and the mounting wall 17. The mounting bolt 35 is inserted through the two. Thereafter, the nut 42 is screwed into the mounting bolt 35 from the outside of the mounting flange 34, so that the wedge portion 33 of the wedge member 30 presses both end portions of the guard member 9 in the divided portion outward, so The contact surface 22 is brought into close contact with the inner surface of the flange portion of the guard member 9. At this time, since the spacer 45 is disposed between the mounting flange 34 and the mounting wall 17 as described above, the pressing of the guard member 9 by the wedge member 30 is stopped by the close contact of the spacer 45, and the spacer 45 is disposed in the placement portion 10. The guard member 9 is fixed in a substantially intimate contact state without being strongly pressed toward the contact surface 22 of the arrangement portion 10. By doing in this way, even if the guard member 9 expands and contracts in the axial direction due to the influence of the temperature change, the expansion and contraction (displacement) of the end position is caused between the leg portion 39 of the pressing member 11 and the end portion of the guard member 9. The gap U is allowed to be absorbed and the end of the guard member 9 is prevented from coming into contact with the presser member 11 (structure).

一方、図７に示すように、上記図１，２に示すガード部材９の長手方向分割部以外では、まくらぎ２の上部に固定された上記固定部材７の配置部１０にガード部材９が配置され、このガード部材９のウエブ部９ａに設けられた固定長穴４４（図１）の上方からワッシャ１３を介して挿通された固定ボルト１４をまくらぎ２のネジ穴４１に螺合することにより、ガード部材９が配置部１０に固定されている。 On the other hand, as shown in FIG. 7, the guard member 9 is arranged on the arrangement portion 10 of the fixing member 7 fixed to the upper part of the sleeper 2 except for the longitudinal division portion of the guard member 9 shown in FIGS. The fixing bolt 14 inserted through the washer 13 from above the fixing elongated hole 44 (FIG. 1) provided in the web portion 9a of the guard member 9 is screwed into the screw hole 41 of the sleeper 2. The guard member 9 is fixed to the arrangement portion 10.

そして、この部分でも、支持壁１６の傾斜面１８とガード部材９との間に楔部材３０が挿入されて固定されている。これにより、楔部材３０の楔部３３がガード部材９を外向きに押圧して、上記配置部１０の当接面２２にガード部材９のフランジ部内面が押圧されて確実に固定される。このように、ガード部材９の分割部以外では、楔部材３０によって配置部１０に配置されたガード部材９を外向きに押圧して確実に配置部１０の当接面２２に密着させて固定している。 Also in this portion, the wedge member 30 is inserted and fixed between the inclined surface 18 of the support wall 16 and the guard member 9. Thereby, the wedge part 33 of the wedge member 30 presses the guard member 9 outward, and the inner surface of the flange part of the guard member 9 is pressed against the contact surface 22 of the arrangement part 10 and is fixed securely. As described above, except for the divided portion of the guard member 9, the guard member 9 disposed on the placement portion 10 is pressed outwardly by the wedge member 30 to be firmly attached and fixed to the contact surface 22 of the placement portion 10. ing.

図８(a) 〜(c) は、図１に示す車輪逸走防止装置による作用の説明図である。以上のように構成された車輪逸走防止装置１によれば、図８(a) に示すように、車輪Ｗが本線レール３から脱線したとしても、車両の下部から突出する構成Ｄは車輪逸走防止装置１に当接することはなく、また、図８(b) に示すように、脱線した車輪Ｗが軌道Ｒの中央部へ移動したとしても、高さが低く抑えられた車輪逸走防止装置１に構成Ｄが当接することはない。そして、図８(c) に示すように、車輪Ｗが車輪逸走防止装置１の車輪受面８に当接して外側の車輪Ｗがまくらぎ２から外れて車両が軌道から逸走するのを防止している状態でも、車両から下向きに突出する構成Ｄと車輪逸走防止装置１（固定部５及び逸走防止部６）との間には所定の隙間Ｓ（例えば、約３０ｍｍ以上）が設けられているので当接することはない。この実施の形態では、固定部５及び逸走防止部６が構成Ｄと同様の隙間Ｓを有するようにしているが、固定部５は更に大きな隙間Ｓとなるようにしてもよい。 FIGS. 8A to 8C are explanatory views of the action of the wheel runaway prevention device shown in FIG. According to the wheel runaway prevention device 1 configured as described above, as shown in FIG. 8 (a), even if the wheel W derails from the main rail 3, the configuration D that protrudes from the lower part of the vehicle has the wheel runaway prevention. As shown in FIG. 8 (b), even if the derailed wheel W moves to the center of the track R, the wheel runaway prevention device 1 is kept low in height. Configuration D will not abut. Then, as shown in FIG. 8 (c), the wheel W is brought into contact with the wheel receiving surface 8 of the wheel runaway prevention device 1 to prevent the outer wheel W from coming off the sleeper 2 and the vehicle from running away from the track. Even when the vehicle is running, a predetermined gap S (for example, about 30 mm or more) is provided between the configuration D projecting downward from the vehicle and the wheel runaway prevention device 1 (the fixed portion 5 and the runaway prevention portion 6). Therefore, it does not contact. In this embodiment, the fixing portion 5 and the runaway prevention portion 6 have the same gap S as in the configuration D. However, the fixing portion 5 may have a larger gap S.

したがって、この車輪逸走防止装置１によれば、車両下部から下向きに突出する構成Ｄを備えた車両でも、その構成Ｄが車輪逸走防止装置１に当接して傷付くことはなく、脱線した車両の軌道逸走を確実に防止することができる。 Therefore, according to the wheel runaway prevention device 1, even if the vehicle has the configuration D that protrudes downward from the lower portion of the vehicle, the configuration D does not come into contact with the wheel runaway prevention device 1 and is not damaged. Orbital runaway can be reliably prevented.

なお、この実施の形態の車輪逸走防止装置１によれば、固定部材７の両側部に固定するガード部材９を小さく分割すれば、持ち運びが容易で作業性良く取付け作業を行うことができる。 In addition, according to the wheel runaway prevention device 1 of this embodiment, if the guard members 9 that are fixed to the both side portions of the fixing member 7 are divided into small parts, the carrying work is easy and the work can be performed with good workability.

図１０(a),(b) に示すように、この実施の形態の固定部材５２は、中央部に上記まくらぎ２に固定するための固定穴５５を有し、その両側部にガード部材５４を配置する配置部５６が張り出すように一体的に設けられている。また、この実施の形態では、固定部材５２の中央部に設けられる支持壁５７と取付壁５８との上部に上記固定穴５５が設けられた上板５９が一体的に形成されている。この上板５９に設けられる上記固定穴５５は、支持壁５７と取付壁５８との上端から固定ボルト６０（図１１(a) ）の頭部が突出しないような窪み部６１に設けられている。さらに、上記支持壁５７には、上述した実施の形態と同様に、楔部材３０（図４と同様の構成）が接する傾斜面６２が形成されている。この傾斜面６２に楔部材３０が接してガード部材５４を幅方向に位置決めする部分が、位置決め部６３である。 As shown in FIGS. 10 (a) and 10 (b), the fixing member 52 of this embodiment has a fixing hole 55 for fixing to the sleeper 2 at the center, and guard members 54 on both sides thereof. Is disposed integrally so as to project. In this embodiment, the upper plate 59 provided with the fixing hole 55 is formed integrally with the upper portion of the support wall 57 and the mounting wall 58 provided at the center of the fixing member 52. The fixing hole 55 provided in the upper plate 59 is provided in the recess 61 so that the head of the fixing bolt 60 (FIG. 11 (a)) does not protrude from the upper ends of the support wall 57 and the mounting wall 58. . Further, the support wall 57 is formed with an inclined surface 62 in contact with the wedge member 30 (the same configuration as in FIG. 4), as in the above-described embodiment. A portion where the wedge member 30 comes into contact with the inclined surface 62 and positions the guard member 54 in the width direction is a positioning portion 63.

また、この実施の形態では、上記したように支持壁５７及び取付壁５８と一体的に上板５９が形成されているため、固定部材５２をまくらぎ２に固定した状態では固定穴５５の周囲が塞がれた状態となるので、上記楔部材３０の取付ボルト６４の頭部を挿入させるＴ字状のボルト穴６５が取付壁５８に設けられている。このＴ字状のボルト穴６５により、取付ボルト６４の頭部をボルト穴６５に挿入し、その取付ボルト６４を水平方向外側にずらすことによりボルト頭部の基部をＴ字状ボルト穴６５で回動阻止している。 In this embodiment, since the upper plate 59 is formed integrally with the support wall 57 and the mounting wall 58 as described above, when the fixing member 52 is fixed to the sleeper 2, Therefore, a T-shaped bolt hole 65 for inserting the head of the mounting bolt 64 of the wedge member 30 is provided in the mounting wall 58. The head of the mounting bolt 64 is inserted into the bolt hole 65 by the T-shaped bolt hole 65, and the base of the bolt head is rotated by the T-shaped bolt hole 65 by shifting the mounting bolt 64 outward in the horizontal direction. The movement is blocked.

さらに、この実施の形態の配置部５６は、ガード部材５４が長方形状断面の角柱材で形成された車輪当接部材６６と、この車輪当接部材６６を連結する連結部材６７，６８（剛性部材）とで構成されているため（図１２）、車輪当接部材６６の下面を配置する平面状に形成されている。この配置部５６には、まくらぎ２にガード部材５４を固定する固定ボルト７１（図９）を挿通するための貫通長穴７３が設けられている。 Further, the arrangement portion 56 of this embodiment includes a wheel contact member 66 in which the guard member 54 is formed of a prismatic material having a rectangular cross section, and connecting members 67 and 68 (rigid members) that connect the wheel contact member 66. ) (FIG. 12), it is formed in a planar shape on which the lower surface of the wheel contact member 66 is disposed. The arrangement portion 56 is provided with a through long hole 73 for inserting a fixing bolt 71 (FIG. 9) for fixing the guard member 54 to the sleeper 2.

図１１(a) ,(b) に示すように、この実施の形態の車輪逸走防止装置５０によれば、固定部材５２がまくらぎ２のネジ穴７７に固定ボルト６０で固定され、この固定部材５２の配置部５６にガード部材５４が配置される。図示するガード部材５４は分割部を示しており、固定部材５２の上部において、角柱材の車輪当接部材６６の中空部分に押え部材６９（厚板材）が挿入され、この押え部材６９の中央部に設けられた固定穴７０に固定ボルト７１が挿通されてまくらぎ２のネジ穴７２に固定されることにより、ガード部材５４が配置部５６に固定されている。 As shown in FIGS. 11 (a) and 11 (b), according to the wheel runaway prevention device 50 of this embodiment, the fixing member 52 is fixed to the screw hole 77 of the sleeper 2 with the fixing bolt 60, and this fixing member. The guard member 54 is arranged at the arrangement portion 56 of 52. The guard member 54 shown in the figure shows a divided portion, and a pressing member 69 (thick plate material) is inserted into a hollow portion of a wheel contact member 66 of a prismatic material at the upper portion of the fixing member 52, and the central portion of the pressing member 69 is shown. The guard bolt 54 is fixed to the arrangement portion 56 by inserting the fixing bolt 71 into the fixing hole 70 provided in the screw hole 72 and fixing the fixing bolt 71 to the screw hole 72 of the sleeper 2.

そして、このガード部材５４と支持壁５７の傾斜面６２との間に楔部材３０が挿入され、この楔部材３０が取付壁５８のボルト穴６５に頭部が挿入された取付ボルト６４にナット７４をねじ込むことにより取付けられる。これにより、ガード部材５４が幅方向外側に押圧されて固定穴７０等のガタ付きをなくして配置部５６に確実に固定される。この実施の形態では、車輪当接部材６６の外側面が車輪受面７８となる。 The wedge member 30 is inserted between the guard member 54 and the inclined surface 62 of the support wall 57, and the wedge member 30 is attached to the mounting bolt 64 in which the head is inserted into the bolt hole 65 of the mounting wall 58 with the nut 74. It is installed by screwing in. As a result, the guard member 54 is pressed outward in the width direction, and is not fixed to the fixing hole 70 or the like, and is securely fixed to the arrangement portion 56. In this embodiment, the outer surface of the wheel contact member 66 is the wheel receiving surface 78.

一方、図１２に示すように、上記ガード部材５４の分割部以外では、ガード部材５４の車輪当接部材６６間がまくらぎ２の配置ピッチと同一ピッチで設けられた角柱状の連結部材６８と板状の連結部材６７とによって連結されている（図９）。板状の連結部材６７が設けられた位置では、まくらぎ２の中央部にガード支持材７５が固定され、このガード支持材７５の上部に連結部材６７が配置され、この連結部材６７がガード支持材７５を貫通する固定ボルト７６（固定具）によってまくらぎ２のネジ穴７７に固定されている。 On the other hand, as shown in FIG. 12, except for the divided portion of the guard member 54, a prismatic connecting member 68 provided between the wheel contact members 66 of the guard member 54 at the same pitch as the arrangement pitch of the sleepers 2 It is connected with a plate-like connecting member 67 (FIG. 9). At the position where the plate-like connecting member 67 is provided, a guard support member 75 is fixed to the center portion of the sleeper 2, and the connecting member 67 is disposed above the guard support member 75, and this connecting member 67 supports the guard. It is fixed to the screw hole 77 of the sleeper 2 by a fixing bolt 76 (fixing tool) penetrating the material 75.

以上のように構成された車輪逸走防止装置５０によっても、上記第１実施の形態と同様に、車輪が脱線したとしても、上述した図８(a) 〜(c) と同様に、車両の下部から下方に突出する構成Ｄは車輪逸走防止装置５０に当接することはなく、脱線した車両の車輪Ｗが車輪逸走防止装置５０の車輪受面７８に当接した状態では、外側の車輪Ｗがまくらぎ２から外れないようにして車両の逸走を防止することができる。このように、この車輪逸走防止装置５０によっても、車両下部から下方に向けて突出する構成Ｄが車輪逸走防止装置５０に当接することなく、脱線した車両の逸走を確実に防止することができる。 Even with the wheel runaway prevention device 50 configured as described above, even if the wheel is derailed as in the first embodiment, the lower part of the vehicle is the same as in the above-described FIG. 8 (a) to (c). The configuration D projecting downward from the wheel does not come into contact with the wheel runaway prevention device 50. When the wheel W of the derailed vehicle is brought into contact with the wheel receiving surface 78 of the wheel runaway prevention device 50, the outer wheel W is not covered. Thus, the vehicle can be prevented from running away. Thus, also by this wheel runaway prevention device 50, the configuration D protruding downward from the lower part of the vehicle does not come into contact with the wheel runaway prevention device 50, and the runaway of the derailed vehicle can be reliably prevented.
