Description

この発明は、列車の脱線を防止するための防止構造に関するものである。なお、ここで、脱線とは、列車の車輪がまくら木の敷設領域の外側にはみ出す状態を指し、列車の車輪がレールから外れるのは、脱輪とする。   The present invention relates to a prevention structure for preventing train derailment. Here, derailment refers to a state in which the train wheel protrudes outside the sleeper laying area, and it is derailment that the train wheel comes off the rail.

地震等の際に、列車の脱線を防止するための従来構成として、軌道を形成する左右のレール間に2条のガードレールを設けた構成が採用され、列車の脱線を軌道レールの内側から防止するようになっている。従って、この構成は、レールが合計4条敷設されることになり、その敷設に手間がかかるものであった。また、まくら木としてコンクリート製や合成樹脂製のものを用いる場合には、4条のレールを敷設できるようにした特別な構成のものを用意する必要がある。   In the event of an earthquake or the like, as a conventional configuration for preventing train derailment, a configuration in which two guard rails are provided between the left and right rails forming the track is employed to prevent train derailment from the inside of the track rail. It is like that. Therefore, in this configuration, a total of four rails are laid, which takes time. Moreover, when using the thing made from concrete or a synthetic resin as a sleeper, it is necessary to prepare the thing of the special structure which enabled laying of 4 rails.

一方、特許文献1に示されるように、列車通過時の振動防止対策として、まくら木を連結して全体として梯子状をなすようにした構成が提案されている。
特開2003−328302号公報
On the other hand, as shown in Patent Document 1, a configuration has been proposed in which sleepers are connected to form a ladder as a whole as a vibration prevention measure when passing through a train.
JP 2003-328302 A

前記特許文献1に記載された構成においては、既設のまくら木をそのまま使用して、軌道を容易に補強することができるため、レールの敷設状態が強固になる。従って、この点から列車の脱線防止に対してある程度の効果を期待できる可能性が存在するものの、前述した現行のガードレールの脱線防止機能には遠く及ばない。   In the configuration described in Patent Document 1, since the track can be easily reinforced by using the existing sleeper as it is, the laying state of the rail becomes strong. Therefore, although there is a possibility that a certain degree of effect can be expected for preventing the derailment of the train from this point, it is far from the above-described current guardrail derailment preventing function.

この発明の目的は、まくら木として特別な構成のものを用いなくても、列車の脱線を有効に抑制できる脱線防止構造を提供することにある。   An object of the present invention is to provide a derailment prevention structure that can effectively suppress derailment of a train without using a sleeper having a special configuration.

上記の目的を達成するために請求項1に記載の発明においては、レールを支持するまくら木列の両端に、レールの延長方向に延びる脱線防止部材を固設し、その脱線防止部材により列車の車輪を受けて、脱線を防止するようにしたことを特徴とするものである。   In order to achieve the above object, in the invention described in claim 1, a derailment preventing member extending in the extension direction of the rail is fixed to both ends of the sleeper row supporting the rail, and the train wheel is provided by the derailment preventing member. In response to this, the derailment is prevented.

従って、脱輪した列車の車輪は、脱線防止部材により受け止められる。このため、脱線を防止することが可能になる。また、まくら木上に固定するものではないため、まくら木として、特別な構成のものを用いる必要はない。   Therefore, the wheels of the derailed train are received by the derailment prevention member. For this reason, it becomes possible to prevent derailment. Moreover, since it is not what fixes to a sleeper tree, it is not necessary to use the thing of a special structure as a sleeper tree.

請求項2に記載の発明においては、請求項1に記載の発明において、前記脱線防止部材はその下部側が道床のバラスト内に埋設されるとともに、上部側がバラストから突出することを特徴とするものである。   The invention according to claim 2 is characterized in that, in the invention according to claim 1, the derailment preventing member has a lower side embedded in the ballast of the roadbed and an upper side protruding from the ballast. is there.

従って、脱線防止部材がバラストにより保持されるため、列車の車輪の脱線防止機能を高めることができる。
請求項3に記載の発明においては、請求項1または2に記載の発明において、前記脱線防止部材は、その上端の高さが、レールの上端面の高さと、それより30mm低い高さの間であることを特徴とするものである。
Therefore, since the derailment prevention member is held by the ballast, the derailment prevention function of the train wheel can be enhanced.
In the invention according to claim 3, in the invention according to claim 1 or 2, the derailment prevention member has an upper end height between the height of the upper end surface of the rail and a height lower by 30 mm. It is characterized by being.

従って、前記のように脱線を防止することが可能になるとともに、脱線防止部材と列車の下部との干渉を避けることができる。
請求項4に記載の発明においては、請求項1〜3のうちのいずれか一項に記載の発明において、前記脱線防止部材は、まくら木の端部の外嵌状態で固定される筒状体を介してまくら木に固定されたことを特徴とするものである。
Therefore, derailment can be prevented as described above, and interference between the derailment prevention member and the lower part of the train can be avoided.
In invention of Claim 4, in the invention as described in any one of Claims 1-3, the said derailment prevention member is a cylindrical body fixed in the external fitting state of the edge part of a sleeper. It is characterized by being fixed to the sleeper tree.

従って、まくら木に対して脱線防止部材の固設のための構成を設ける必要がなく、構成が簡単になる。
請求項5に記載の発明においては、請求項1〜4のうちのいずれか一項に記載の発明において、レールの延長方向に隣接する脱線防止部材間に、10〜70mmの幅の間隙を設けたことを特徴とするものである。
Therefore, it is not necessary to provide a structure for fixing the derailment prevention member to the sleeper, and the structure is simplified.
According to a fifth aspect of the present invention, in the invention according to any one of the first to fourth aspects, a gap having a width of 10 to 70 mm is provided between derailment prevention members adjacent to each other in the rail extension direction. It is characterized by that.

従って、脱線防止部材に高温による伸びが生じても、脱線防止部材間の干渉や、その干渉による脱線防止部材の曲がりを防止することが可能になる。   Therefore, even when the derailment prevention member is elongated due to high temperature, it is possible to prevent interference between the derailment prevention members and bending of the derailment prevention member due to the interference.

この発明によれば、簡単な構造で、かつ特別な施工を実行することなく列車の脱線を未然に防止することが可能になる。   According to the present invention, it is possible to prevent a train from derailing with a simple structure and without performing special construction.

以下、この発明を具体化した実施形態を、図面に従って詳細に説明する。
図5に示すように、バラスト11aが敷かれた道床12には、四角柱状のまくら木13が所定間隔をおいて敷設されている。そして、これらのまくら木13の上面には、左右のレール14が敷設固定されて有道床軌道11を構成している。
DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments embodying the present invention will be described below in detail with reference to the drawings.
As shown in FIG. 5, square pillar-shaped sleepers 13 are laid at predetermined intervals on the road bed 12 on which the ballast 11 a is laid. The left and right rails 14 are laid and fixed on the upper surfaces of the sleepers 13 to form the roadbed track 11.

脱線防止部材としての金属材料よりなる長四角板状の補強部材16は、まくら木13の両側においてレール14の長さ方向に延びるように固設されている。これらの補強部材16とまくら木13の両端部とは連結体17によって連結されている。このように補強部材16を介してまくら木13を連続的にすることによって有道床軌道11が補強されている。   Long rectangular plate-shaped reinforcing members 16 made of a metal material as a derailment preventing member are fixed on both sides of the sleeper 13 so as to extend in the length direction of the rails 14. These reinforcing members 16 and both ends of the sleeper 13 are connected by a connecting body 17. In this way, the bedded track 11 is reinforced by making the sleeper 13 continuous through the reinforcing member 16.

図1及び図2に示すように、連結体17には、金属材料よりなる四角板状の連結板18と、収容部としての略四角筒状の筒状体としての収容筒19とが一体状に固定されている。この収容筒19には、まくら木13の端部が収容されている。収容筒19とまくら木13の間には、図1に二点鎖線で示す介装材20が介装されている。そして、連結体17には前記補強部材16が固定されている。   As shown in FIG. 1 and FIG. 2, the connecting body 17 is integrally formed with a square plate-like connecting plate 18 made of a metal material and a housing cylinder 19 as a substantially rectangular tubular body as a housing portion. It is fixed to. An end of the sleeper 13 is accommodated in the accommodating cylinder 19. Between the storage cylinder 19 and the sleeper 13, an intervention material 20 indicated by a two-dot chain line in FIG. 1 is interposed. The reinforcing member 16 is fixed to the connecting body 17.

図1及び図2に示すように、収容筒19は、まくら木13の端部より若干大きく形成され、まくら木13の端部が容易に挿入することが可能である。この収容筒19の上壁には、ねじ孔21が螺刻され、位置決めボルト22が螺挿されるようになっている。この位置決めボルト22がねじ孔21に螺挿されると、図3に示すように収容筒19に収容されたまくら木13の上面は、位置決めボルト22の先端によって押し下げられる。そして、まくら木13の端部下面は、収容筒19の内底に圧接されるとともに、まくら木13の上面と収容筒19の内部上面には、隙間が設けられるようになっている。さらに、収容筒19に対するまくら木13の挿入深さを調節して、まくら木13の端面と収容筒19の奥壁面に隙間を設定することができる。   As shown in FIGS. 1 and 2, the housing cylinder 19 is formed slightly larger than the end of the sleeper 13, and the end of the sleeper 13 can be easily inserted. A screw hole 21 is screwed into the upper wall of the housing cylinder 19 and a positioning bolt 22 is screwed therein. When the positioning bolt 22 is screwed into the screw hole 21, as shown in FIG. 3, the upper surface of the sleeper 13 housed in the housing cylinder 19 is pushed down by the tip of the positioning bolt 22. The lower surface of the end portion of the sleeper 13 is pressed against the inner bottom of the housing cylinder 19, and a gap is provided between the upper surface of the sleeper 13 and the inner upper surface of the housing cylinder 19. Further, the insertion depth of the sleeper 13 with respect to the housing cylinder 19 can be adjusted to set a gap between the end surface of the sleeper 13 and the back wall surface of the housing cylinder 19.

図2及び図3に示すように、まくら木13の上面と収容筒19の内上面との間の隙間、まくら木13の両側面上部と収容筒19の内側面との間の隙間、及びまくら木13の端面と収容筒19の奥壁面との間の隙間には、介装材20が介装されている。この介装材20によって、まくら木13と連結体17とが強固に固定されている。介装材20の材料としては、例えば合成樹脂、セメント、モルタル等が挙げられる。   As shown in FIGS. 2 and 3, the gap between the upper surface of the sleeper 13 and the inner upper surface of the accommodation cylinder 19, the gap between the upper part of both sides of the sleeper 13 and the inner surface of the accommodation cylinder 19, and the sleeper 13 An intervening material 20 is interposed in the gap between the end surface and the inner wall surface of the housing cylinder 19. The sleeper 13 and the connecting body 17 are firmly fixed by the interposing material 20. Examples of the material of the intervention material 20 include synthetic resin, cement, and mortar.

図1に示すように、連結板18の上部4箇所には、長孔としての縦長円状の高さ調整長孔23が透設されている。一方、補強部材16の適当位置には、2箇所ずつ長孔としての横長円状の取付長孔24が透設されている。そして、連結板18が補強部材16に当接したとき、取付長孔24と高さ調整長孔23とが十字状になるように設定されている。   As shown in FIG. 1, longitudinally elongated height adjusting long holes 23 as long holes are formed through the upper four places of the connecting plate 18. On the other hand, two oblong mounting elongated holes 24 are formed at appropriate positions of the reinforcing member 16 as long holes. And when the connection board 18 contact | abuts to the reinforcement member 16, the attachment long hole 24 and the height adjustment long hole 23 are set so that it may become a cross shape.

連結板18に補強部材16に当設された状態において、高さ調整長孔23及び取付長孔24には、固定部材としてのボルト25がワッシャ26を介して挿入されている。そして、固定部材としてのナット27にボルト25が締め付けられることによって連結体17に補強部材16が固定されている。このようにした連結体17がまくら木13に固定されることによって、補強部材16を介してまくら木13が連結される。なお、補強部材16は輸送し易い長さに形成される。   In a state where the reinforcing member 16 is in contact with the connecting plate 18, a bolt 25 as a fixing member is inserted into the height adjusting long hole 23 and the mounting long hole 24 via a washer 26. The reinforcing member 16 is fixed to the connecting body 17 by tightening the bolt 25 to the nut 27 as a fixing member. The sleeper 13 is connected to the sleeper 13 through the reinforcing member 16 by fixing the connecting body 17 thus formed to the sleeper 13. The reinforcing member 16 is formed to a length that is easy to transport.

図6に示すように、連結体17に補強部材16が固定された後、ボルト25の先端及びナット27は道床12のバラスト11aに埋没されている。従って、仮にボルト25の破損等によって外れることがあっても、軌道上に飛び出さないようになっている。   As shown in FIG. 6, after the reinforcing member 16 is fixed to the connecting body 17, the tip of the bolt 25 and the nut 27 are buried in the ballast 11 a of the road bed 12. Therefore, even if the bolt 25 is detached due to breakage or the like, it does not jump out on the track.

カーブやトンネル出口等の必要箇所において、図1,図2,図3,図4及び図7に2点鎖線示すように、前記補強部材16は、上下幅の大きいものが用いられ、その上端16aの高さLが前記レール14の上端面の高さと対応している。このように、上下幅の大きい補強部材16が脱線防止部材を構成している。すなわち、補強部材16の上端16aの高さLは、レール14の上端面と同一の高さと、その上端面よりも30mm低い高さとの間に位置している。そして、図6から明らかなように、補強部材16の下部側がバラスト11a内に埋設されるとともに、上部側がバラスト11aから突出している。図7に示すように、隣接する補強部材16の端部間には10〜70mm程度の隙間16bが形成されている。   As shown by a two-dot chain line in FIGS. 1, 2, 3, 3, 4 and 7, the reinforcing member 16 having a large vertical width is used at a necessary portion such as a curve or a tunnel exit, and its upper end 16a. The height L corresponds to the height of the upper end surface of the rail 14. Thus, the reinforcing member 16 having a large vertical width constitutes a derailment preventing member. That is, the height L of the upper end 16a of the reinforcing member 16 is located between the same height as the upper end surface of the rail 14 and a height 30 mm lower than the upper end surface. As is clear from FIG. 6, the lower side of the reinforcing member 16 is embedded in the ballast 11a, and the upper side protrudes from the ballast 11a. As shown in FIG. 7, a gap 16 b of about 10 to 70 mm is formed between the ends of the adjacent reinforcing members 16.

従って、列車の車輪がレール14から脱輪した場合、その車輪は、補強部材16によって受け止められる。このため、列車の車輪が、まくら木13の敷設範囲の外側に移動してしまう脱線を未然に防止できる。   Therefore, when a train wheel is removed from the rail 14, the wheel is received by the reinforcing member 16. For this reason, it is possible to prevent derailment of the train wheels moving outside the sleeper 13 laying range.

本実施形態によって発揮される効果について、以下に記載する。
・ この実施形態においては、収容筒19はまくら木13の端部を包み込むようになっている。そして、収容筒19とまくら木13の隙間には介装材20が介装され、連結体17がまくら木13に固定されている。さらに、連結体17に補強部材16に固定され、軌道を補強するようになっている。この構成によると、既設のまくら木13に特別な加工を施さなくても、連結体17を固定することができる。従って、既設のまくら木をそのまま使用して、軌道を容易に補強することができる。
The effects exhibited by this embodiment will be described below.
-In this embodiment, the accommodating cylinder 19 wraps the end part of the sleeper 13. An intervening material 20 is interposed in the gap between the accommodation cylinder 19 and the sleeper 13, and the coupling body 17 is fixed to the sleeper 13. Furthermore, the connecting member 17 is fixed to the reinforcing member 16 to reinforce the track. According to this structure, the connection body 17 can be fixed even if it does not give special processing to the existing sleeper 13. Therefore, the track can be easily reinforced by using the existing sleeper as it is.

・ この実施形態においては、収容筒19はまくら木13の端部を袋状に包み込むようになっている。この構成によると、連結体17にまくら木13を安定して固定することができる。従って、補強部材16を安定して固定することができる。   -In this embodiment, the accommodating cylinder 19 wraps the end of the sleeper 13 in a bag shape. According to this configuration, the sleeper 13 can be stably fixed to the connector 17. Therefore, the reinforcing member 16 can be stably fixed.

・ そして、この実施形態においては、前記連結体17に固定した補強部材16により列車の脱線を抑制できるようになっている。従って、脱線防止を目的とした専用の部材を設ける必要がなく、構成及び施工や整備が容易である。しかも、脱線防止を目的とした部材を固定するための構造をまくら木13に設ける必要がないため、まくら木13として特別な構成のものを用いる必要がない。   In this embodiment, the derailment of the train can be suppressed by the reinforcing member 16 fixed to the connecting body 17. Therefore, there is no need to provide a dedicated member for the purpose of preventing derailment, and the configuration, construction and maintenance are easy. Moreover, since it is not necessary to provide the sleeper 13 with a structure for fixing a member intended to prevent derailment, it is not necessary to use a special structure as the sleeper 13.

・ 隣接する補強部材16間に隙間16bが形成されているため、夏期に補強部材16が高温になったとしても、その高温による伸びを隙間16bで吸収でき、隣接する補強部材16どうしが干渉したり、あるいは干渉により補強部材16が曲がったりすることを未然に防止することが可能になる。   Since the gap 16b is formed between the adjacent reinforcing members 16, even if the reinforcing member 16 becomes hot in summer, the elongation due to the high temperature can be absorbed by the gap 16b, and the adjacent reinforcing members 16 interfere with each other. Or bending of the reinforcing member 16 due to interference can be prevented.

以上に述べた実施形態の効果を列挙すれば以下の通りである。
・ 補強部材16により列車の脱線を抑止できる。
・ 前記補強部材16はその下部側が道床12のバラスト11a内に埋設されているため、所定位置で安定保持され、脱線防止に有効である。
The effects of the embodiment described above are listed as follows.
The train derailment can be suppressed by the reinforcing member 16.
The reinforcing member 16 has a lower portion embedded in the ballast 11a of the road bed 12, and is thus stably held at a predetermined position, which is effective for preventing derailment.

・ 前記補強部材16は、その上端の高さが、レール14の上端面の高さと、それより30mm低い高さの間であるため、脱線を有効に防止することが可能になるとともに、補強部材16と列車の下部との干渉を避けることができる。   The reinforcing member 16 has an upper end height between the height of the upper end surface of the rail 14 and a height 30 mm lower than that, so that derailment can be effectively prevented and the reinforcing member Interference between 16 and the lower part of the train can be avoided.

・ 前記補強部材16は、まくら木13の端部の外嵌状態で固定される筒状体としての収容筒19を介してまくら木13に固定されている。従って、まくら木13に対して補強部材16の固設のための構成を設ける必要がなく、構成が簡単になる。   The reinforcing member 16 is fixed to the sleeper 13 via a storage cylinder 19 as a cylindrical body that is fixed in an externally fitted state of the end of the sleeper 13. Therefore, it is not necessary to provide a configuration for fixing the reinforcing member 16 to the sleeper 13 and the configuration is simplified.

なお、前記実施形態を次のように変更して具体化することも可能である。
・ 補強部材16の上端16aの高さをレール14の上端面の高さよりも高くすること。ただし、このように構成した場合は、補強部材16と列車の下部とが干渉しない高さに抑える必要がある。
It should be noted that the embodiment described above can be modified and embodied as follows.
The height of the upper end 16 a of the reinforcing member 16 is made higher than the height of the upper end surface of the rail 14. However, in the case of such a configuration, it is necessary to suppress the height so that the reinforcing member 16 and the lower part of the train do not interfere with each other.

・ 補強部材16と収容筒19とを一体化すること。すなわち、補強部材16に収容筒19を固定し、連結板18を省略すること。   -The reinforcing member 16 and the housing cylinder 19 are integrated. That is, the housing cylinder 19 is fixed to the reinforcing member 16 and the connecting plate 18 is omitted.
