Description

本発明は、連結された複数の鉄道車両を積載して走行する複数の貨物車両の間に設けられる渡りレール装置に関する。   The present invention relates to a transition rail device provided between a plurality of freight vehicles that travel by loading a plurality of connected rail vehicles.

現在、軌間寸法の異なる線路区間(以下「異軌間軌道」という)において列車を連続的に移動させるための技術が種々提案されている。その一つとして、所定軌道を走行する複数の鉄道車両からなる鉄道列車を積載する、当該鉄道列車よりも広い軌間の軌道を走行可能な貨物列車(連結された複数の貨物車両)を使用して、広い軌間の線路区間は鉄道列車を積載した貨物列車で走行し、狭い軌間の線路区間では積載されていた鉄道列車で走行する技術を挙げることができる(例えば、特許文献1参照)。
特開2005−262914号公報(第3図)
Currently, various techniques for continuously moving trains in track sections having different gauge dimensions (hereinafter referred to as “different gauge tracks”) have been proposed. One of them is the use of freight trains (multiple connected freight vehicles) that can carry a railroad track that is wider than the railroad train that carries a railroad train that consists of a plurality of railcars that travel on a predetermined track. An example of the technology is that the track section between the wide gauges travels with a freight train loaded with a railroad train, and the railroad section loaded between the narrow rail track sections travels with a railway train (for example, see Patent Document 1).
Japanese Patent Laying-Open No. 2005-262914 (FIG. 3)

上記の従来技術においては、鉄道列車を貨物列車に積載する場合に、鉄道列車を構成する各鉄道車両を一両ずつ貨物列車に格納する作業を行っていては煩雑に過ぎ、その積載作業には多大な作業負担と時間が必要となってしまうため、より効率的な方法として、連結された複数の貨物車両の一端側から連結された鉄道車両が乗り入れて他端側まで移動することで積載する技術が取り入れられている。
その場合、鉄道列車は各貨物車両の連結部を渡って移動しなければならず、そのための渡り構造が必須となる。
貨物車両内には、鉄道列車が移動するための一対のレールが設けられており、渡り構造としては、一方の貨物車両から他方の貨物車両へ隙間が生じないように一対のレールを延出したものが考えられる。しかしながら、車両間に隙間なくレールを渡すと、貨物列車が曲線の線路区間を走行する際に、曲線における各貨物車両間の内輪側のレール同士が接触するおそれがあるため、貨物列車の走行が直線若しくは緩やかな曲線の線路区間に制限されるという問題があった。
In the above prior art, when loading a railroad train on a freight train, it is too complicated to store each railcar constituting the railroad train one by one in the freight train. Since a large work load and time are required, a more efficient method is to load by connecting a connected rail vehicle from one end side of a plurality of connected freight vehicles and moving to the other end side. Technology is incorporated.
In that case, the railway train must move across the connecting part of each freight vehicle, and a crossover structure for that is essential.
In the freight vehicle, there is a pair of rails for the railroad train to move, and as a transition structure, the pair of rails was extended so that there was no gap from one freight vehicle to the other freight vehicle Things can be considered. However, if the rails are passed between the vehicles without gaps, the rails on the inner ring side between the freight vehicles on the curve may come into contact with each other when the freight train runs on the curved track section. There is a problem that the track is limited to a straight or gently curved track section.

本発明は、貨物列車の曲線区間走行に制限を与えることなく連結された複数の貨物車両間を連結された複数の鉄道車両が円滑に移動可能とすることをその目的とする。   An object of the present invention is to enable a plurality of rail vehicles connected between a plurality of connected freight vehicles to move smoothly without restricting traveling in a curved section of a freight train.

請求項1に記載の発明は、連結された複数の鉄道車両を積載する連結された複数の貨物車両の相互間を前記各鉄道車両が移動することを可能とする渡りレール装置であって、
前記各貨物車両の鉄道車両積載面上には前記鉄道車両が走行するための一対の積載レールが設けられ、

前記各貨物車両の端部の双方に設けられ、前記各渡り部の一端部と他端部とをそれぞれ支持し、前記渡り部を水平に回動可能に支持する台座部と、
を備えることを特徴とする。
The invention according to claim 1 is a cross rail device that enables each rail vehicle to move between a plurality of connected freight vehicles that carry a plurality of connected rail vehicles.
On each railcar loading surface of each freight vehicle is provided with a pair of loading rails for the railcar to travel,
A pair of slide members that are stretched between two connected freight vehicles and that have a fitting structure and can be expanded and contracted by sliding the fitting portion, A structure in which the railway vehicle can travel in the same manner as the loading rail, and a pair of crossovers arranged on an extension line of the loading rail;
A pedestal that is provided at both ends of each freight vehicle, supports one end and the other end of each crossover , and supports the crossover horizontally;
It is characterized by providing.

請求項2に記載の発明は、請求項1に記載の渡りレール装置であって、
前記台座部は、前記渡り部を仰角方向にも回動可能に支持することを特徴とする。
The invention according to claim 2 is the transition rail device according to claim 1,
The pedestal portion supports the crossing portion so as to be rotatable also in an elevation angle direction.

請求項3に記載の発明は、請求項1または2のいずれか一項に記載の渡りレール装置であって、
前記各渡り部が具備する前記スライド部材の一方のほぼ全長にわたって、積載する前記鉄道車両の車輪のフランジ内側面を当該フランジよりも内側から支えるガイドレールを有することを特徴とする。
なお、ここでいう内側とは一対の渡り部の内側のことであり、一対の渡り部が並んでいる状態で当該渡り部に対して他方の渡り部側を示し、外側とは一対の渡り部が並んでいる状態で当該渡り部に対して他方の渡り部側とは逆側をいう。また、一対のレールに対しても、内側、外側は同様のことを示す。
The invention according to claim 3 is the transition rail device according to any one of claims 1 and 2,
It has a guide rail which supports the flange inner surface of the wheel of the railway vehicle to be loaded from the inner side of the flange over the substantially entire length of one of the slide members included in each of the crossing portions.
The inner side here means the inner side of the pair of transition parts, and shows the other transition part side with respect to the transition part in a state where the pair of transition parts are arranged, and the outer side means the pair of transition parts. In a state where the lines are lined up, the other side of the crossing portion is opposite to the crossing portion. The same applies to the inside and outside of the pair of rails.

請求項1に記載の発明によれば、貨物車両が複数連結された貨物列車が水平かつ真っ直ぐなレールの軌道上に配置された状態で、貨物列車の一端から鉄道車両が内部に積載される。その際、鉄道車両は連結されたまま貨物列車内を進行する。そして、連結された各貨物車両間を渡りレール装置の渡り部で渡して鉄道車両の移動が行われる。
一方、貨物列車の走行時において、例えば、線路区間に曲がりが生じていた場合、互いに対向する積載レールのなす角度には変化が生じるとともに、各貨物車両間の隙間の距離は曲線の内輪側と外輪側で違いが生じる。しかしながら、角度の変化に対しては台座部が有する水平方向の回転軸に従って回動することによって、隙間の距離の変化に対しては、内輪側では渡り部が収縮し、外輪側では渡り部が伸長することによって対応し、従って、貨物列車は渡りレール装置によって制限を受けることなく曲線区間を円滑に走行することができる。
また、原則的には、貨物列車が直線区間にあるときに鉄道車両の積載が行われると前記したが、貨物列車の線路区間に曲がりが生じていた場合でも渡りレール装置が各貨物車両間を接続し続けるので、鉄道車両が貨物車両内を進行する際にある程度の曲がりがあっても、各貨物車両間を渡らせることが可能となる。
According to the first aspect of the present invention, the railway vehicle is loaded from one end of the freight train in a state in which the freight train in which a plurality of freight vehicles are connected is arranged on a horizontal and straight rail track. At that time, the railway vehicle travels in the freight train while being connected. Then, the railway vehicle is moved across the connected freight vehicles at the crossing portion of the rail device.
On the other hand, when the freight train is running, for example, if the track section is bent, the angle between the loading rails facing each other changes, and the distance between the freight vehicles is different from the inner ring side of the curve. Differences occur on the outer ring side. However, by rotating according to the horizontal rotation axis of the pedestal portion with respect to the change in angle, the crossover portion contracts on the inner ring side and the crossover portion on the outer ring side with respect to the change in gap distance. It responds by extending | stretching, Therefore, a freight train can drive | work smoothly a curve area, without being restrict | limited by a crossing rail apparatus.
In principle, the railcars are loaded when the freight train is in a straight section. However, even if there is a bend in the track section of the freight train, the crossing rail device is connected between the freight vehicles. Since the connection is continued, even if there is a certain degree of bending when the railway vehicle travels in the freight vehicle, it is possible to cross between the freight vehicles.

請求項2に記載の発明によれば、線路区間の高低差によっては、互いに対向する積載レールが仰角方向に角度を生じることもあるが、その場合は台座部が有する仰角方向の回転軸に従って回動することによって円滑に走行することができる。
また、原則的には、貨物列車が起伏のない直線区間にあるときに鉄道車両の積載が行われることが望ましいが、貨物列車の線路区間に起伏を生じていたとしても渡りレール装置が各貨物車両間を接続し続けるので、鉄道車両が貨物車両内を進行する際にある程度の起伏があっても、各貨物車両間を渡らせることが可能となる。
According to the invention described in claim 2, depending on the height difference of the track section, the loading rails facing each other may form an angle in the elevation direction. In this case, the rotation is performed according to the rotation axis in the elevation direction of the pedestal portion. It can run smoothly by moving.
In principle, it is desirable that railcars are loaded when the freight train is in a straight section with no undulations. Since the vehicles are continuously connected to each other, even if there is a certain level of undulation when the railway vehicle travels in the freight vehicle, it is possible to cross the freight vehicles.

請求項3に記載の発明によれば、渡りレール装置がフランジ内側面を当該フランジよりも内側から支えるガイドレールを有することから、積載する鉄道車両の車輪が内側に変位してしまうことを抑止することが可能で、例えば、渡り部が伸長したときに、二つのスライド部材が伸長方向にスライドして、二つのスライド部材双方によって構成される上面の一部の区間に幅が狭くなる部分、つまり実質的にレールとレールの間の幅(軌間)が拡大しているのと同様な部分(例えば図3のS1)を生じるような構造を採っている場合であっても、反対側の渡り部に設けられたガイドレールと反対側の車輪のフランジ内側面とが接触することによって鉄道車両の横方向の変位を防ぐ。   According to the third aspect of the present invention, since the transition rail device has the guide rail that supports the inner surface of the flange from the inside of the flange, it is possible to prevent the wheels of the railway vehicle to be loaded from being displaced inward. For example, when the crossing portion is extended, the two slide members slide in the extension direction, and the width of a part of the upper surface constituted by both of the two slide members becomes narrow, that is, Even in the case of adopting a structure that produces a portion (for example, S1 in FIG. 3) that is substantially the same as the width between rails (gauge) is enlarged, the crossing portion on the opposite side The guide rail provided on the wheel and the inner surface of the flange on the opposite side of the wheel come into contact with each other, thereby preventing lateral displacement of the railway vehicle.

(貨物車両及び鉄道車両)
以下、本発明の実施の形態を、図を用いて詳細に説明する。
図1は、発明の実施形態である渡りレール装置10を積載した貨物列車100を示す側面図である。
貨物列車100は、図1に示すように、複数の連結された貨物車両110と、これら貨物車両110に接続されて牽引する機関車(図示略)とから構成されている。かかる貨物列車100は、当該貨物列車100が走行する軌道よりも軌間の狭い軌道を走行する鉄道列車200を積載して運行を行う車両である。積載される鉄道列車200も、複数の連結された鉄道車両210から構成され、各鉄道車両210が動力を持っていない場合には必要に応じて機関車が接続されていてもよい。
(Freight vehicles and railway vehicles)
Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.
FIG. 1 is a side view showing a freight train 100 loaded with a transit rail device 10 according to an embodiment of the invention.
As shown in FIG. 1, the freight train 100 includes a plurality of connected freight vehicles 110 and a locomotive (not shown) that is connected to the freight vehicles 110 and towed. The freight train 100 is a vehicle that carries and operates a railroad train 200 that travels on a narrower track than the track on which the freight train 100 travels. The loaded railway train 200 is also composed of a plurality of connected railway vehicles 210, and if each railway vehicle 210 has no power, a locomotive may be connected as necessary.

上記各貨物車両110は、上記鉄道列車200を積載するために、“鉄道車両積載面”としての台枠111の上面に鉄道列車200の軌間幅に合わせた一対の積載レール112が前後方向に沿って設けられている。
そして、鉄道列車200を貨物列車100に積載する際には、連結された貨物車両110の一端部側から鉄道列車200が乗り入れて、貨物車両110の他端部側に移動可能となるように、各貨物車両110の間には、鉄道列車200が渡ることを可能とするための渡りレール装置10が設けられている。
なお、鉄道列車200の積載は、貨物列車100がなるべく直線状の線路区間に停車しているときに行われ、貨物列車100の走行時には鉄道列車200の移動は行われない。
また、貨物車両110の前後長さと鉄道車両210の前後長さとは各連結器間の長さで一致するように設定され、鉄道列車200の積載時には、当該鉄道列車200の各連結器201と貨物列車100の各連結器101とは前後方向について同位置となるように鉄道列車200は停車し保持される。従って、積載時に一両の鉄道車両210が二両の貨物車両110にまたがって積載されることはない。
In order to load the railway train 200, each of the freight vehicles 110 has a pair of loading rails 112 in the front-rear direction on the upper surface of a frame 111 serving as a “railway vehicle loading surface”. Is provided.
When the railway train 200 is loaded on the freight train 100, the railway train 200 enters from one end side of the connected freight vehicle 110 and can move to the other end side of the freight vehicle 110. Between each freight vehicle 110, the crossing rail apparatus 10 for enabling the railroad train 200 to cross is provided.
The railroad train 200 is loaded when the freight train 100 is stopped on a linear track section as much as possible, and the railroad train 200 is not moved when the freight train 100 travels.
Further, the longitudinal length of the freight vehicle 110 and the longitudinal length of the railway vehicle 210 are set so as to coincide with each other between the couplers, and when the railway train 200 is loaded, the coupler 201 and the cargo of the railway train 200 are loaded. The railway train 200 is stopped and held so as to be in the same position in the front-rear direction with each coupler 101 of the train 100. Therefore, one railcar 210 is not loaded across two freight vehicles 110 at the time of loading.

(渡りレール装置の全体構成)
図2は渡りレール装置10の平面図、図3は斜視図、図4は側面図、図5は図2におけるX−X線に沿った断面図である。
渡りレール装置10は、連結された二つの貨物車両110の間に掛け渡されると共に、“スライド部材”としての外側スライド部材21と内側スライド部材22と両者の摺動部分がくさび状に切り欠かれた切欠部21a,22aに嵌合し両者を摺動可能に接続する噛部材23とからなる渡り部20と、各貨物車両110の端部の双方に設けられ、各渡り部20の一端部と他端部とをそれぞれ支持し、仰角回転軸43および水平回転軸44によって二次元の回動を可能とする台座部40,40と、を備えている。
(Overall configuration of the transition rail device)
2 is a plan view of the cross rail device 10, FIG. 3 is a perspective view, FIG. 4 is a side view, and FIG. 5 is a cross-sectional view taken along line XX in FIG.
The transit rail device 10 is stretched between two linked freight vehicles 110, and the outer slide member 21 and the inner slide member 22 as "slide members" and the sliding portions of both are cut out in a wedge shape. Provided at both ends of each freight vehicle 110, and at one end portion of each crossover portion 20, which is provided at both ends of each freight vehicle 110. And pedestal portions 40 and 40 that respectively support the other end portion and enable two-dimensional rotation by the elevation rotation shaft 43 and the horizontal rotation shaft 44.

(台座部)
台座部40は、土台となる台座台41と、台座台41の下部に設けられた水平回転軸44と、台座台41の上部に設けられた仰角軸受42と、仰角軸受42により支持される仰角回転軸43とを備えた構成となっている。仰角回転軸43は、詳しくは後述する渡り部20を支持している。
貨物車両110の台枠111の前後それぞれの端部には、図4に示すように、他の部位よりも一段低くなっている上面平滑な段部111aがあって、そこに四角い板状の台座台41,41が水平回転軸44,44を介して回動可能に設置されている。水平回転軸44は段部111aに設けられた図示しない軸受部により垂直方向を向いて回転可能に支持されており、台座台41,41の下面側に固定装備されている。つまり各台座台41はこれにより垂直軸回りに回動可能となっている。
各台座台41の上面には一対の仰角軸受42,42が固定立設されており、これらの仰角軸受42,42は仰角回転軸43が挿通される開口部が水平な同一直線状に形成されており、それらの内側に仰角回転軸43を回転可能とする軸受構造が形成されている。つまり、これにより仰角回転軸43は水平軸回りに回転可能となっている。
仰角回転軸43は一対の仰角軸受42,42の間において、外側スライド部材21又は内側スライド部材22の一端部を支持している。
各台座部40は、外側スライド部材21又は内側スライド部材22の端部を、仰角回転軸43と水平回転軸44とにより垂直軸回りと水平軸回りに回動可能に支持することを可能としている。
なお、水平回転軸44が滑らかに回動可能なようにベアリング等を介して段部111aに設置してもよい。
なお、段部111aは、主に、渡り部20の高さを積載レール112の高さに合わせるために設けられているため、より必要な部分にのみ段部を設けてもよいし、台座部40を小型化するなどの方法が可能であれば、必ずしも設けずに台枠111と同じ高さのままでもよい。
(Pedestal)
The pedestal portion 40 includes a pedestal base 41 as a base, a horizontal rotation shaft 44 provided at the lower part of the pedestal base 41, an elevation bearing 42 provided at the upper part of the pedestal base 41, and an elevation angle supported by the elevation bearing 42. The rotation shaft 43 is provided. The elevation angle rotation shaft 43 supports a crossing portion 20 described later in detail.
As shown in FIG. 4, at the front and rear ends of the base frame 111 of the freight vehicle 110, there is a stepped portion 111 a having a smooth upper surface that is one step lower than other portions, and there is a square plate-like base. The bases 41 and 41 are rotatably installed via horizontal rotation shafts 44 and 44. The horizontal rotation shaft 44 is rotatably supported in a vertical direction by a bearing portion (not shown) provided on the step portion 111a , and is fixedly mounted on the lower surface side of the pedestals 41 and 41. That is, each pedestal base 41 can be rotated around the vertical axis.
A pair of elevation bearings 42, 42 are fixedly erected on the upper surface of each pedestal base 41, and these elevation bearings 42, 42 are formed in the same straight line with an opening through which the elevation angle rotation shaft 43 is inserted. A bearing structure that allows the elevation angle rotation shaft 43 to rotate is formed inside thereof. That is, as a result, the elevation angle rotation shaft 43 can rotate around the horizontal axis.
The elevation rotation shaft 43 supports one end of the outer slide member 21 or the inner slide member 22 between the pair of elevation bearings 42, 42.
Each pedestal portion 40 can support the end portion of the outer slide member 21 or the inner slide member 22 so as to be rotatable about a vertical axis and a horizontal axis by an elevation angle rotation shaft 43 and a horizontal rotation shaft 44. .
In addition, you may install in the step part 111a through a bearing etc. so that the horizontal rotating shaft 44 can rotate smoothly.
Since the step portion 111a is mainly provided to adjust the height of the crossover portion 20 to the height of the loading rail 112, the step portion may be provided only in a more necessary portion, or the pedestal portion. If a method such as downsizing 40 is possible, the height may be the same as the height of the frame 111 without necessarily providing it.

(渡り部)
渡り部20は、図2から図5に示すように、外側スライド部材21と内側スライド部材22および噛部材23が摺動可能に組み合わされた構造をしており、外側スライド部材21と内側スライド部材22を組み合わせた状態でそれらの面を鉄道車両210が走行することが可能な形状となっている。
(Transition part)
As shown in FIGS. 2 to 5, the crossover portion 20 has a structure in which an outer slide member 21, an inner slide member 22, and a biting member 23 are slidably combined. The outer slide member 21 and the inner slide member In such a state, the rail vehicle 210 can travel on these surfaces in a state where 22 are combined.

渡り部20を構成する外側スライド部材21および内側スライド部材22は、互いにその対向面に棒状の噛部材23が嵌合する溝部21a,22aが形成されており、それぞれの溝部21a,22aの断面形状は、いずれも図5に示すような略台形状となっている。そして、溝部21a,22aの溝開口側に比して溝底部側の幅が広くなるように形成されている。
一方、噛部材23は、断面形状が二つの台形の上底同士を接合した略鼓状の棒状体であり、その断面形状の一方の台形部分が外側スライド部材21の溝部21aに嵌合し、その断面形状の他方の台形部分が内側スライド部材22の溝部22aに嵌合している。これにより、外側スライド部材21と内側スライド部材22とが分離しないよう接続し、それぞれが摺動することによって渡り部20の伸縮を可能としている。
また、鉄道車両210の車輪211が当接する渡り部20の上面は、伸長方向に沿った境界線により外側スライド部材21側と内側スライド部材22側とに二分されており、外側スライド部材21側の上面と内側スライド部材22側の上面とは同一高さに形成されている。そして、かかる構造により、渡り部20が伸長した場合、外側スライド部材21側の上面と内側スライド部材22側の上面とは伸長方向にズレを生じるため、図3に示すように、伸長距離に応じて、内側スライド部材22の先端部から外側スライド部材21を支持する台座部40までの間に隙間S1を生じると共に、外側スライド部材21の先端部から内側スライド部材22を支持する台座部40までの間に隙間S2を生じる。
なお、外側スライド部材21と内側スライド部材22の形状は必ずしも図5に示す形状でなくともよく、外側スライド部材21と内側スライド部材22が摺動可能で、渡り部20が伸縮可能であれば、どのような断面形状を有していてもよい。ただし、少なくとも渡り部20の上面の車輪211が走行する面は、渡り部20が伸長した際に拡大する隙間S1等によって車輪211が降下する落差を少なくするために、外側スライド部材21と内側スライド部材22の双方で構成される必要がある。また、外側スライド部材21の上面と内側スライド部材22の上面は必ずしも同一高さに形成されていなくともよく、上面を走行する車輪211の形状に合わせて斜面状にしたり、同じく段差を設けてもよい。
The outer slide member 21 and the inner slide member 22 constituting the crossover portion 20 are formed with groove portions 21a and 22a on the opposite surfaces of which the rod-like biting member 23 is fitted, and the sectional shapes of the respective groove portions 21a and 22a. Are substantially trapezoidal as shown in FIG. And it forms so that the width | variety of the groove bottom part side may become wide compared with the groove opening side of groove part 21a, 22a.
On the other hand, the biting member 23 is a substantially drum-like rod-shaped body in which the upper bases of two trapezoidal cross-sectional shapes are joined, and one trapezoidal portion of the cross-sectional shape is fitted into the groove portion 21a of the outer slide member 21, The other trapezoidal portion of the cross-sectional shape is fitted in the groove portion 22 a of the inner slide member 22. Thereby, the outer slide member 21 and the inner slide member 22 are connected so as not to be separated, and the crossing portion 20 can be expanded and contracted by sliding.
Moreover, the upper surface of the crossover part 20 with which the wheels 211 of the railway vehicle 210 abut is divided into an outer slide member 21 side and an inner slide member 22 side by a boundary line along the extension direction. The upper surface and the upper surface on the inner slide member 22 side are formed at the same height. With this structure, when the crossing portion 20 is extended, the upper surface on the outer slide member 21 side and the upper surface on the inner slide member 22 side are displaced in the extension direction, so as shown in FIG. In addition, a gap S1 is generated between the distal end portion of the inner slide member 22 and the pedestal portion 40 that supports the outer slide member 21, and from the distal end portion of the outer slide member 21 to the pedestal portion 40 that supports the inner slide member 22. A gap S2 is generated between them.
The shapes of the outer slide member 21 and the inner slide member 22 do not necessarily have to be the shapes shown in FIG. 5. If the outer slide member 21 and the inner slide member 22 are slidable and the crossover portion 20 is extendable, It may have any cross-sectional shape. However, at least the surface on which the wheel 211 on the upper surface of the crossover portion 20 travels is formed on the outer slide member 21 and the inner slide in order to reduce a drop in which the wheel 211 descends due to a gap S1 or the like that expands when the crossover portion 20 extends. It is necessary to be constituted by both members 22. Further, the upper surface of the outer slide member 21 and the upper surface of the inner slide member 22 do not necessarily have to be formed at the same height, and may be inclined according to the shape of the wheel 211 traveling on the upper surface or may be provided with a step. Good.

また、外側スライド部材21と内側スライド部材22の摺動面は平面ではなく、段差Dが設けられている。これは、強度の問題で噛部材23を中央に配置したい要請と、渡り部20が伸長した際に拡がる隙間S1によって上面を通過する車輪211が受ける影響を最小限に抑えたい要請との折り合いから設けられたものである。渡り部20は、図3に示すように、伸縮するための余裕として隙間S1を有しており、当然ながら伸長した時には隙間S1も拡大する。渡り部20とその上面を通過する車輪211は、図5に示すような位置関係にある。隙間S1が車輪211の通過に即座に重大な影響を及ぼすことはないが、図示のように車輪211は内側(フランジ側)が大径となる様にその踏面が傾斜しているため、車輪211が隙間S1を通過する際には車輪211が多少降下し、衝撃や振動が発生する。これらの衝撃や振動を緩和するために、外側スライド部材21の上面の幅を広くしている。なお、外側スライド部材21の上面の幅を広くすると内側スライド部材22の上面の幅が狭くなるため、隙間S2において鉄道車両210の重量を支えきれなくならないように内側スライド部材22の上面の幅を設定している。
なお、噛部材23の形状は必ずしも図5に示す形状でなくともよく、外側スライド部材21と内側スライド部材22が分離不可能で、渡り部20が伸縮可能であれば、どのような断面形状を有していてもよい。
なお、噛部材23は必ずしも必要ではなく、外側スライド部材21と内側スライド部材22が直接嵌合可能なようにそれぞれの断面形状を設定してもよい。例えば、外側スライド部材21と噛部材23を一体に形成した部材と内側スライド部材22を嵌合させるようにしたり、内側スライド部材22と噛部材23を一体に形成した部材と外側スライド部材21を嵌合させるようにしたり、といった方法も採用可能である。
In addition, the sliding surfaces of the outer slide member 21 and the inner slide member 22 are not flat but are provided with a step D. This is a combination of a request to place the biting member 23 in the center due to a problem of strength and a request to minimize the influence of the wheel 211 passing through the upper surface by the gap S1 that expands when the crossover portion 20 extends. It is provided. As shown in FIG. 3, the crossover portion 20 has a gap S <b> 1 as a margin for expansion and contraction, and naturally the gap S <b> 1 also expands when extended. The crossover part 20 and the wheels 211 passing through the upper surface thereof are in a positional relationship as shown in FIG. The gap S1 does not immediately have a significant influence on the passage of the wheel 211, but the wheel 211 is inclined so that the inner side (flange side) has a large diameter as shown in the figure. When the wheel passes through the gap S1, the wheel 211 is slightly lowered, and an impact or vibration is generated. In order to mitigate these impacts and vibrations, the width of the upper surface of the outer slide member 21 is increased. If the width of the upper surface of the outer slide member 21 is increased, the width of the upper surface of the inner slide member 22 is reduced. Therefore, the width of the upper surface of the inner slide member 22 is set so that the weight of the railway vehicle 210 cannot be supported in the gap S2. It is set.
The shape of the biting member 23 is not necessarily the shape shown in FIG. 5, and any cross-sectional shape can be used as long as the outer slide member 21 and the inner slide member 22 are not separable and the transition portion 20 can be expanded and contracted. You may have.
Note that the biting member 23 is not always necessary, and the cross-sectional shapes may be set so that the outer slide member 21 and the inner slide member 22 can be directly fitted. For example, a member formed integrally with the outer slide member 21 and the biting member 23 and the inner slide member 22 are fitted, or a member formed integrally with the inner slide member 22 and the biting member 23 and the outer slide member 21 are fitted. It is also possible to adopt a method such as combining them.

なお、渡り部20の横幅は積載レール112の横幅と必ずしも同一である必要はなく、レール内側の面が揃っていて鉄道車両210の車輪211のフランジの通過を阻害しないよう配置されていればよい。   Note that the width of the crossover 20 does not necessarily have to be the same as the width of the loading rail 112, as long as the rail inner surfaces are aligned and arranged so as not to obstruct the passage of the flanges of the wheels 211 of the railway vehicle 210. .

渡り部20は、図2に示すように、貨物車両110の一対である左右の積載レール112,112ごとに個別に設けられている。つまり、一方の貨物車両110の左側のレールと他方の貨物車両110の左側のレールとを接続する渡り部20と、一方の貨物車両110の右側のレールと他方の貨物車両110の右側のレールとを接続する渡り部20とがそれぞれ配備されている。
これら左右の渡り部20,20は全く同一の構造であって、前後方向の向きのみが入れ替わっており、従って、一方の渡り部20においてレールの内側を向いている面は他方の渡り部20においてもレールの内側を向いている。
As shown in FIG. 2, the crossover unit 20 is provided individually for each of the left and right loading rails 112, 112 that are a pair of the cargo vehicles 110. That is, the crossover 20 that connects the left rail of one cargo vehicle 110 and the left rail of the other cargo vehicle 110, the right rail of one cargo vehicle 110, and the right rail of the other cargo vehicle 110 Are connected to each other.
These left and right transition parts 20 and 20 have exactly the same structure, and only the direction in the front-rear direction is interchanged. Therefore, the surface facing the inside of the rail in one transition part 20 is the same in the other transition part 20. Also facing the inside of the rail.

内側スライド部材22にはガイドレール22cも設けられている。
ガイドレール22cは、内側スライド部材22のほぼ全長にわたって形成され、図5の断面形状に示すように、内側スライド部材22上を通過する車輪211のフランジを当該フランジよりも内側から支えるために、フランジが入ることは可能だが外側スライド部材21から車輪211が外れない程度の幅を開けて内側スライド部材22の上面とほぼ同じ高さまで迫り出した形状をしている。
例えば、渡り部20が大きく伸長して上述のように隙間S1が拡大した部分に鉄道車両210の車輪211がさしかかった時に、鉄道車両210に対して当該渡り部20にフランジを押付ける向きに何らかの力が加わると、フランジを支えるべき内側スライド部材22がないため、当該車輪211にはその力に逆らう力が働く要素がないが、かかるガイドレール22cを反対側の渡り部20が有していることで、当該ガイドレール22cに反対側の車輪211のフランジ内側面211aが接触することにより反力が発生し、車輪211が大きく変位することを防ぐことができる。
上述のように、左右の渡り部20,20は全く同一の構造であって、前後方向の向きのみを入れ替えて設けられているため、渡り部20の隙間S1がある位置の反対側の渡り部20の同じ位置には必ずガイドレール22cが存在することとなっている。
The inner slide member 22 is also provided with a guide rail 22c.
The guide rail 22c is formed over substantially the entire length of the inner slide member 22, and, as shown in the cross-sectional shape of FIG. 5, the flange 211 of the wheel 211 passing over the inner slide member 22 is supported by a flange in order to support the flange from the inside. However, the width of the wheel 211 is not increased from the outer slide member 21 so that the wheel 211 protrudes to almost the same height as the upper surface of the inner slide member 22.
For example, when the wheel 211 of the railroad vehicle 210 approaches the portion where the crossover portion 20 is greatly extended and the gap S1 is expanded as described above, the direction in which the flange is pressed against the railroad vehicle 210 against the crossover portion 20 is When force is applied, there is no inner slide member 22 to support the flange, so the wheel 211 does not have an element that works against the force, but the crossing portion 20 on the opposite side has such a guide rail 22c. Thus, a reaction force is generated when the flange inner side surface 211a of the opposite wheel 211 comes into contact with the guide rail 22c, and the wheel 211 can be prevented from being largely displaced.
As described above, since the left and right transition parts 20 and 20 have exactly the same structure and are provided with only the front and rear direction switched, the transition part on the opposite side of the position where the gap S1 of the transition part 20 is located. The guide rail 22c always exists at the same position of 20.

渡り部20は、その両端に台座部40が備える仰角回転軸43が挿入される軸受け部21b,22bが設けられ、それぞれ台座部40,40に接続されている。
なお、渡り部20と積載レール112の間には極力隙間がない方が鉄道車両210の走行には都合がよいが、渡り部20が台座部40によって動くことができる程度の余裕を持たせるとともに、渡り部20の各端部を面取りして渡り部20が動きやすいようにしてもよい。
なお、軸受け部21b,22bには、挿入される仰角回転軸43が滑らかに回動するようにベアリング等を取付けてもよい。
The crossover portion 20 is provided with bearing portions 21b and 22b into which the elevation rotation shaft 43 provided in the pedestal portion 40 is inserted at both ends, and is connected to the pedestal portions 40 and 40, respectively.
In addition, it is convenient for the traveling of the railcar 210 that there is no gap as much as possible between the crossover part 20 and the loading rail 112, but there is a margin that allows the crossover part 20 to be moved by the pedestal part 40. Alternatively, each end portion of the crossover portion 20 may be chamfered so that the crossover portion 20 can move easily.
Note that a bearing or the like may be attached to the bearing portions 21b and 22b so that the inserted elevation angle rotation shaft 43 can smoothly rotate.

渡り部20の伸縮のストローク長は、貨物列車100が加速・減速をする際等に発生する衝撃や荷重を緩和するために連結器101が有する緩衝ゴムの伸縮について考慮されており、緩衝ゴムの伸縮によって、渡り部20が最短となる長さにまで収縮したり、伸長し過ぎて外側スライド部材21、内側スライド部材22および噛部材23が外れたりすることがないよう設定されている。
また、渡り部20の伸縮のストローク長は、貨物列車100が走行する区間に設定される曲率半径が最小となる曲線における伸縮についても考慮されており、当該曲線区間において、貨物列車100の内輪側の渡り部20は余裕を持って収縮し、外輪側の渡り部20は外側スライド部材21、内側スライド部材22および噛部材23が外れることなく伸長するよう設定されている。
さらに、当該曲線区間における伸縮に加えて、緩衝ゴムによる伸縮が重畳される場合にも、内輪側の渡り部20は余裕を持って収縮し、外輪側の渡り部20は外側スライド部材21、内側スライド部材22および噛部材23が外れることなく伸長するよう設定されている。
The expansion / contraction stroke length of the crossover portion 20 is taken into consideration for the expansion / contraction of the buffer rubber included in the coupler 101 in order to reduce the impact and load generated when the freight train 100 accelerates / decelerates. It is set so that the crossover portion 20 does not contract to the shortest length due to expansion and contraction, or the outer slide member 21, the inner slide member 22, and the biting member 23 are not detached due to excessive expansion.
In addition, the expansion / contraction stroke length of the crossover portion 20 is also considered for expansion / contraction in a curve having a minimum curvature radius set in a section in which the freight train 100 travels. The crossover portion 20 contracts with a margin, and the crossover portion 20 on the outer ring side is set so as to extend without the outer slide member 21, the inner slide member 22 and the biting member 23 coming off.
Furthermore, in addition to the expansion and contraction in the curved section, also when the expansion and contraction by the buffer rubber is superimposed, the transition part 20 on the inner ring side contracts with a margin, and the transition part 20 on the outer ring side has the outer slide member 21 and the inner side. The slide member 22 and the biting member 23 are set so as to extend without coming off.

(渡りレール装置の作用及び効果)
貨物列車100に鉄道列車200を積載する際には、貨物列車100の一端部側から鉄道列車200を乗り入れて、貨物列車100内を鉄道列車200を移動させることにより行われる。そして、当該積載は、原則として、左右の曲がりと起伏のない線路区間に貨物列車100を置いて行われる。
貨物列車100内を鉄道列車200が進行する際には、各貨物車両110間を渡りレール装置10の渡り部20,20が渡して移動を可能とする。
(Operation and effect of the transition rail device)
When the railway train 200 is loaded on the freight train 100, the railway train 200 is loaded from one end side of the freight train 100, and the railway train 200 is moved in the freight train 100. In principle, the loading is performed by placing the freight train 100 on a track section without left and right bends and undulations.
When the railroad train 200 travels in the freight train 100, the crossovers 20 and 20 of the rail device 10 cross over between the freight vehicles 110 to enable movement.

また、貨物列車100の走行時において、例えば図6に示すように、線路区間に曲がりが生じていた場合、互いに対向する積載レール112のなす角度θ1には変化が生じるとともに、各貨物車両110間の隙間の距離は曲線の内輪側L1と外輪側L2で違いが生じる。しかしながら、角度θ1の変化に対しては台座部40が有する水平回転軸44に従って回動することによって、隙間の距離L1,L2の変化に対しては、内輪側では渡り部20が収縮し、外輪側では渡り部20が伸長することによって対応し、従って、貨物列車100は渡りレール装置10による制限を受けることなく曲線区間を円滑に走行することができる。   Further, when the freight train 100 travels, for example, as shown in FIG. 6, when the track section is bent, the angle θ <b> 1 formed by the loading rails 112 facing each other changes, and the freight vehicles 110 are connected. The distance between the gaps differs between the inner ring side L1 and the outer ring side L2 of the curve. However, by rotating according to the horizontal rotation axis 44 of the pedestal portion 40 with respect to the change in the angle θ1, the crossover portion 20 contracts on the inner ring side with respect to the change in the gap distances L1 and L2, and the outer ring On the side, this is dealt with by the extension of the crossover 20, and thus the freight train 100 can travel smoothly in the curved section without being restricted by the crossover rail device 10.

さらには、線路区間の高低差によっては、例えば図7に示すように、互いに対向する積載レール112が仰角方向に角度θ2を生じることもあるが、その場合は台座部40が有する仰角回転軸43に従って回動することによって、貨物列車100は渡りレール装置10による制限を受けることなく起伏のある区間を円滑に走行することができる。   Furthermore, depending on the height difference of the track section, for example, as shown in FIG. 7, the stacking rails 112 facing each other may generate an angle θ2 in the elevation direction. In this case, the elevation rotation shaft 43 of the pedestal portion 40 is included. , The freight train 100 can smoothly travel in an undulating section without being restricted by the crossover rail device 10.

また、原則的には、貨物列車100が直線区間にあるときに鉄道車両210の積載が行われるが、貨物列車100の線路区間に曲がりや起伏が生じていた場合でも渡りレール装置10が各貨物車両110間を接続し続けるので、鉄道車両210が貨物車両110内を進行する際にある程度の曲がりや起伏があっても、各貨物車両110間を渡らせることが可能となる。   In principle, the railcar 210 is loaded when the freight train 100 is in a straight section. However, even when the rail section of the freight train 100 is bent or undulated, the crossing rail device 10 is used for each freight. Since the vehicles 110 continue to be connected, even if there is a certain degree of bending or undulation when the railway vehicle 210 travels in the freight vehicle 110, the freight vehicles 110 can be crossed.

また、渡りレール装置10がフランジ内側面211aを当該フランジよりも内側から支えるガイドレール22cを有することから、積載する鉄道車両210の車輪211が内側に変位してしまうことを抑止することが可能で、渡り部20が伸長したときに、外側スライド部材21および内側スライド部材22が伸長方向にスライドして、外側スライド部材21および内側スライド部材22双方によって構成される上面の一部の区間に幅が狭くなる部分、つまり実質的にレールとレールの間の幅(軌間)が拡大しているのと同様な部分を生じても、反対側の渡り部20に設けられたガイドレール22cと反対側の車輪211のフランジ内側面211aとが接触することによって鉄道車両210の横方向の変位を防ぎ、脱輪等も防ぐことができる。   In addition, since the transition rail device 10 has the guide rail 22c that supports the flange inner surface 211a from the inside of the flange, it is possible to prevent the wheels 211 of the railway vehicle 210 to be loaded from being displaced inward. When the crossing portion 20 is extended, the outer slide member 21 and the inner slide member 22 slide in the extension direction, and the width of a part of the upper surface constituted by both the outer slide member 21 and the inner slide member 22 has a width. Even if a narrowed portion, that is, a portion that is substantially the same as the width between the rails (gauge) is enlarged, the portion on the opposite side to the guide rail 22c provided on the opposite crossing portion 20 is formed. Contact with the flange inner side surface 211a of the wheel 211 can prevent lateral displacement of the railcar 210 and prevent wheel removal and the like.

また、図5に示すように、渡りレール装置10上を鉄道車両210が通過する際に車輪211が接する渡り部20の上面は外側スライド部材21と内側スライド部材22の双方で構成されることから、渡り部20の伸縮状態に関わらず車輪211は必ず外側スライド部材21と内側スライド部材22の一方または双方の上面と接しながら積載レール112,112間を渡るため、鉄道車両210は滑らかに各貨物車両110間を渡ることができる。   Further, as shown in FIG. 5, the upper surface of the crossover portion 20 with which the wheels 211 come into contact when the railcar 210 passes over the crossover rail device 10 is constituted by both the outer slide member 21 and the inner slide member 22. Regardless of the expansion / contraction state of the crossover part 20, the wheel 211 always crosses between the loading rails 112 and 112 while being in contact with the upper surface of one or both of the outer slide member 21 and the inner slide member 22. The vehicle 110 can be crossed.

また、渡りレール装置10を用いることによって、鉄道列車200を貨物列車100に積載した後でも、貨物車両110,110間の連結部分に関して特別な作業を行うことなくそのまま貨物列車100が走行を開始できるなど、鉄道列車200の異軌間軌道における連続的な移動をより円滑に行うことができる。   Further, by using the transit rail device 10, the freight train 100 can start running without performing any special work on the connecting portion between the freight vehicles 110 and 110 even after the railroad train 200 is loaded on the freight train 100. For example, the continuous movement of the railroad train 200 on the different-gauge track can be performed more smoothly.

(その他)
なお、渡りレール装置10を、貨物車両110と貨物車両110との間に設置する代りに、貨物車両110と地上に設けられたレールとの間に設置することにより、鉄道列車200を地上から貨物列車100へと積載する場面でも使用することができる。ただし、この場合は、鉄道列車200の積載を完了した時点で渡り部20を取り外すなどの分離作業が必要となる。
(Other)
Instead of installing the transit rail device 10 between the freight vehicle 110 and the freight vehicle 110, the rail train 200 can be freighted from the ground by installing it between the freight vehicle 110 and a rail provided on the ground. It can also be used when loading on the train 100. However, in this case, separation work such as removal of the crossover portion 20 is required when the loading of the railway train 200 is completed.
