Description

本発明は、地震等の際に、鉄道車両が転倒するのを防止する鉄道車両の転倒防止構造に関する。   The present invention relates to a fall prevention structure for a railway vehicle that prevents the railway vehicle from falling during an earthquake or the like.

車両(鉄道車両)が橋梁・高架橋上で地震力を受けた場合、その上を走行する車両は水平方向慣性力を受けて脱線する可能性がある。
そこで、地震時に車両の走行安全性を確保する方法の一つとして、特許文献1に記載のように、高架橋の固有振動数を高め、鉄道車両の水平方向の固有振動数と離す技術がある。
この技術は、互いに対向する位置にて立設された一対の柱状橋脚と該柱状橋脚の頂部に架け渡された梁とからラーメン構造を形成するとともに前記一対の柱状橋脚及び前記梁を含む面内空間に逆V字状をなすブレース材を配置し、該ブレース材の頂部近傍を所定のエネルギー吸収ダンパーを介して前記梁の中央近傍に接合し、両端を前記一対の柱状橋脚の中間高さ位置近傍にそれぞれ接合してなる鉄道用高架橋の下部構造であって、該鉄道用高架橋の橋軸直交方向の固有振動数が2Hz以上となるように構成したものである。
また、急曲線など、鉄道車両の走行性が悪くなることが予測される箇所には予め脱線防止レールなどが設置されている。
特開平11−323826号公報
When a vehicle (railway vehicle) receives an earthquake force on a bridge or viaduct, a vehicle traveling on the vehicle may derail due to a horizontal inertial force.
Therefore, as one of methods for ensuring the traveling safety of the vehicle at the time of an earthquake, there is a technique of increasing the natural frequency of the viaduct and separating it from the natural frequency in the horizontal direction of the railway vehicle, as described in Patent Document 1.
In this technique, a ramen structure is formed from a pair of columnar piers erected at positions facing each other and a beam spanned on the top of the columnar pier, and an in-plane including the pair of columnar piers and the beam. A brace material having an inverted V-shape is disposed in the space, the vicinity of the top of the brace material is joined to the vicinity of the center of the beam via a predetermined energy absorbing damper, and both ends are positioned at intermediate height positions of the pair of columnar piers. It is a substructure of a railway viaduct that is joined in the vicinity, and is configured such that the natural frequency in the direction orthogonal to the bridge axis of the railway viaduct is 2 Hz or more.
In addition, a derailment prevention rail or the like is installed in advance in a place such as a sharp curve where it is predicted that the traveling performance of the railway vehicle will deteriorate.
JP-A-11-323826

しかし、上記のような従来技術においては、特に、高架橋等の高さの高い構造物では、構造物の水平方向の振動が大きく、かつ車両にとっても最も厳しい固有振動数で振動するため、脱線を防ぐことは困難である。
そして、脱線が起きた場合には、車両はレールによる水平方向の拘束を失い、高架橋等の構造物上を不安定な状態で走行することになり、場合によっては車両が転倒するに至ることもある。このような車両の転倒を防止する技術については現在のところ具体的なものがない。
However, in the prior art as described above, particularly in a structure with a high height such as a viaduct, the horizontal vibration of the structure is large and the vehicle vibrates at the most severe natural frequency. It is difficult to prevent.
When derailment occurs, the vehicle loses the horizontal restraint due to the rails and travels on a structure such as a viaduct in an unstable state. In some cases, the vehicle may fall over. is there. There is currently no specific technique for preventing such a vehicle from falling.

本発明は上記事情に鑑みてなされたものであり、地震等の際に、鉄道車両が転倒するのを防止することができる鉄道車両の転倒防止構造を提供することを課題としている。   This invention is made | formed in view of the said situation, and makes it a subject to provide the fall prevention structure of a railway vehicle which can prevent that a railway vehicle falls down in the case of an earthquake etc.

上記課題を解決するために、請求項1に記載の発明は、例えば図に示すように、鉄道車両の転倒防止構造であって、鉄道車両7が走行するレール6,6の両側に、車両転倒防止体20がレール6の延在方向に所定間隔で、かつ、建築限界の外側500mm以内に位置するようにして設けられており、
前記車両転倒防止体20は、支柱21と、この支柱21に取付けられたガイド部材23とを備えており、
前記ガイド部材23は前記鉄道車両7が脱線した際に、該鉄道車両7の側面を相対的に摺動または転動することを特徴とする。
In order to solve the above-mentioned problem, the invention described in claim 1 is a structure for preventing overturning of a railway vehicle, as shown in FIG. 1 , for example, on both sides of rails 6 and 6 on which the railway vehicle 7 travels. The fall prevention body 20 is provided at a predetermined interval in the extending direction of the rail 6 so as to be located within 500 mm outside the building limit,
The vehicle overturn prevention body 20 includes a support column 21 and a guide member 23 attached to the support column 21.
The guide member 23 is characterized by sliding or rolling relative to the side surface of the railcar 7 when the railcar 7 is derailed.

本発明によれば、車両転倒防止体が、鉄道車両が走行するレールの両側に、車両転倒防止体がレールの延在方向に所定間隔で、かつ、建築限界の外側500mm以内に位置するようにして設けられているので、鉄道車両が地震等によって脱線して傾いた場合、鉄道車両が車両転倒防止体に当接(衝突)して、この車両転倒防止体によって支持されてそれ以上の傾きが阻止されるので、鉄道車両の転倒を未然に防止できる。
また、鉄道車両が地震等によって脱線して傾いた場合、鉄道車両が車両転倒防止用体に当接(衝突)するが、その際にガイド部材が鉄道車両の側面を相対的に摺動または転動するので、鉄道車両が車両転倒防止体に当接(衝突)した際の衝撃が軽減され、よって、鉄道車両の損傷を軽減できる。
さらに、車両転倒防止体は、支柱と、この支柱に取付けられたガイド部材とを備えたものであるから、既存のレールにおいてその両側に容易に設置できる。
According to the present invention, the vehicle overturn prevention body is positioned on both sides of the rail on which the railway vehicle runs, and the vehicle overturn prevention body is positioned at a predetermined interval in the rail extending direction and within 500 mm outside the building limit. Therefore, when a railway vehicle derails and tilts due to an earthquake or the like, the railway vehicle abuts (collises) with the vehicle fall prevention body, and is supported by the vehicle fall prevention body and further tilted. Since it is blocked, it is possible to prevent the rolling stock from falling.
In addition, when the railway vehicle derails and tilts due to an earthquake or the like, the railway vehicle contacts (collises) with the vehicle fall prevention body. At this time, the guide member relatively slides or rolls on the side surface of the railway vehicle. Therefore, the impact when the railway vehicle comes into contact (collision) with the vehicle overturn prevention body is reduced, and thus damage to the railway vehicle can be reduced.
Furthermore, since the vehicle overturn prevention body includes a support and a guide member attached to the support, it can be easily installed on both sides of an existing rail.

以下、図面を参照して本発明の実施の形態について説明する。

The fall prevention structure of this example can be applied to the fall prevention structure of a railway vehicle traveling on a rail provided on an existing bridge, viaduct, embankment or the like.
On both sides of the existing rails 6, 6, the vehicle fall prevention bodies 20 are provided at predetermined intervals in the extending direction of the rails 6 and located within 500 mm outside the building limit. The distance between the vehicle overturn prevention bodies 20, 20 adjacent to each other in the extending direction of the rail 6 is set slightly shorter than the length of one vehicle. In FIG. 1 , since one side of the rails 6 and 6 is shown, the vehicle overturn prevention body 20 is provided on one side of the rails 6 and 6, but is actually provided opposite to each other on both sides.

車両転倒防止体20は、H形鋼で形成されて路盤に立設された支柱21と、この支柱21を補強支持する斜めの補強部材22と、支柱21の上端部に取付けられたガイド部材23とを備えている。
補強部材22は鋼材で形成されたもので、その上端部が支柱21に固定され、下端部が路盤に埋設固定されている。また、補強部材22はレール側、つまり走行する車両側と反対側から支柱21を補強している。
ガイド部材23は、鉛直軸回りに回転可能なローラ23であり、このローラ23は、支柱21の上端部にアーム23aを介して取付けられている。
The vehicle overturn prevention body 20 is made of a H-shaped steel and is erected on a roadbed 21, an oblique reinforcing member 22 that reinforces and supports the column 21, and a guide member 23 that is attached to the upper end of the column 21. And.
The reinforcing member 22 is formed of a steel material, and an upper end portion thereof is fixed to the column 21 and a lower end portion is embedded and fixed to the roadbed. The reinforcing member 22 reinforces the support column 21 from the rail side, that is, the side opposite to the traveling vehicle side.
The guide member 23 is a roller 23 rotatable around a vertical axis, and this roller 23 is attached to the upper end portion of the support column 21 via an arm 23a.

このように本実施の形態では、レール6の両側に、車両転倒防止体20がレール6の延在方向に所定間隔で、かつ、建築限界の外側500mm以内に位置するようにして設けられているので、鉄道車両7が地震等によって脱線して傾いた場合、鉄道車両7が車両転倒防止体20に当接して、この車両転倒防止体20によって支持されてそれ以上の傾きが阻止されるので、鉄道車両7の転倒を未然に防止できる。
また、鉄道車両7が地震等によって脱線して傾いた場合、鉄道車両7が車両転倒防止用体20に当接するが、その際にガイド部材(ローラ)23が鉄道車両7の側面を相対的に転動するので、鉄道車両7が車両転倒防止体20に当接した際の衝撃が軽減され、よって、鉄道車両7の損傷を軽減できる。
さらに、車両転倒防止体20は、支柱21と、補強材22と、支柱21に取付けられたガイド部材22とを備えたものであるから、既存のレール6においてその両側に容易に設置できる。
Thus, in this embodiment, the vehicle fall prevention bodies 20 are provided on both sides of the rail 6 so as to be positioned at a predetermined interval in the extending direction of the rail 6 and within 500 mm outside the building limit. Therefore, when the railway vehicle 7 is derailed and tilted due to an earthquake or the like, the railway vehicle 7 comes into contact with the vehicle fall prevention body 20 and is supported by the vehicle fall prevention body 20 to prevent further tilting. The fall of the railway vehicle 7 can be prevented beforehand.
Further, when the railway vehicle 7 is derailed and tilted due to an earthquake or the like, the railway vehicle 7 comes into contact with the vehicle fall prevention body 20, and at that time, the guide member (roller) 23 relatively moves the side surface of the railway vehicle 7. Since it rolls, the impact when the railway vehicle 7 comes into contact with the vehicle overturn prevention body 20 is reduced, and thus damage to the railway vehicle 7 can be reduced.
Furthermore, since the vehicle fall prevention body 20 includes the support column 21, the reinforcing member 22, and the guide member 22 attached to the support column 21, it can be easily installed on both sides of the existing rail 6.
