Description

本発明は、鉄道車両に衝突した動物を車両下に巻き込まないように線路外へ排除するための排障器に関する。 The present invention relates to an obstruction device for removing an animal that has collided with a railroad vehicle from the railroad track so as not to get caught under the vehicle.

現在、鉄道軌道は様々な地域を結ぶように張り巡らされており、都市部から山間部にまで亘っている。例えば、野生動物が生息する山間部などでは、線路を野生動物が横切るようなことがあり、時として鉄道車両と動物が衝突することがある。
鉄道車両に衝突した動物を車両下に巻き込んで車両機器が破損してしまうと、輸送障害が発生してしまうので、鉄道車両に衝突した動物を線路外へ排除するための排障器を車両の妻面の下部に取り付けることがある。 Currently, railroad tracks are stretched to connect various areas, extending from urban areas to mountainous areas. For example, in mountainous areas where wild animals live, wild animals may cross railroad tracks, and sometimes railroad cars and animals may collide.
If an animal that collides with a railroad vehicle is caught under the vehicle and the vehicle equipment is damaged, a transportation obstacle will occur. Therefore, an obstruction device for removing the animal that collided with the railroad vehicle from the railroad track is installed. It may be attached to the bottom of the wife's face.

そのような排障器として、衝突した動物に致命的な損傷を与えずに線路外へ跳ね飛ばし、跳ね飛ばされた動物が自力で逃げることを可能にするよう、スポンジゴムなどの緩衝材を用いて作製されたものが知られている（例えば、特許文献１参照。）。 As such an obstruction device, a cushioning material such as sponge rubber is used so that the collided animal can be bounced off the railroad track without causing fatal damage and the bounced animal can escape by itself. Is known (see, for example, Patent Document 1).

特開２０１３−１２３９５１号公報Japanese Unexamined Patent Publication No. 2013-123951

しかしながら、上記特許文献１の排障器の場合、緩衝材によるクッション性を好適に発現させるためにその厚みを増すことで、排障器のサイズが大型化する傾向にあり、降雪地域を走行する鉄道車両に取り付けて使用するには不向きなものであった。
具体的には、降雪地域を走行する鉄道車両の妻面の下部には、軌道に積もった雪を押し退けるスノープラウと呼ばれる除雪板が配設されており、その除雪板よりも前側に大型の排障器を取り付けると、除雪板による除雪の妨げになってしまうという問題があった。
特に、大型で厚みのある排障器は車両の妻面から突き出すように取り付けられるので、その表面に雪が積もり易く、積もった雪の重みで緩衝材製の排障器が変形して不具合が生じることがあり問題であった。 However, in the case of the obstruction device of Patent Document 1, the size of the obstruction device tends to increase by increasing the thickness in order to preferably develop the cushioning property of the cushioning material, and the vehicle travels in a snowfall area. It was unsuitable for use by attaching it to a railroad vehicle.
Specifically, a snow plow called a snow plow that pushes away the snow accumulated on the track is arranged at the lower part of the wife surface of the railroad vehicle traveling in the snowfall area, and a large exhaust plate is placed in front of the snow plow. When an obstacle is attached, there is a problem that the snow removal board hinders the removal of snow.
In particular, since a large and thick obstruction device is attached so as to protrude from the wife's surface of the vehicle, snow easily accumulates on the surface, and the weight of the accumulated snow deforms the obstruction device made of cushioning material, causing problems. Sometimes it was a problem.

本発明の目的は、鉄道車両に取り付けられている除雪板と好適に併用することができる排障器を提供することである。 An object of the present invention is to provide an obstruction device that can be suitably used in combination with a snow removal plate attached to a railway vehicle.

上記目的を達成するため、この発明は、
鉄道車両の妻面の下部に配設されている除雪板よりも進行方向の前側に位置するように前記鉄道車両に取り付けられる排障器であって、
当該排障器は、正面視上下方向に延在する複数の縦材と、正面視左右方向に延在する複数の横材とが交差した格子形状を有しており、
前記横材は前記縦材の前面側に配されるように組み付けられているようにした。 In order to achieve the above object, the present invention
An obstruction device attached to the railroad vehicle so as to be located on the front side in the traveling direction of the snow removal plate arranged at the lower part of the end surface of the railroad vehicle.
The obstruction device has a lattice shape in which a plurality of vertical members extending in the vertical direction of the front view and a plurality of horizontal members extending in the horizontal direction of the front view intersect.
The horizontal member was assembled so as to be arranged on the front side of the vertical member.

かかる構成の排障器は、複数の縦材と複数の横材とを交差させて組み付けた格子形状を有しており、衝突した動物との接触面積が小さく、その動物との摩擦係数を小さくすることができるので、排障器に衝突した動物を排障器に沿って滑らせるように線路外へ排除し易くなる。
特に、正面視左右方向に延在する横材が縦材の前面側に配されるように組み付けられているので、排障器に衝突した動物を複数の横材に沿って滑らせ易くなっており、排障器に衝突した動物を線路外へ排除する誘導を好適に行うことができる。 The obstruction device having such a configuration has a lattice shape in which a plurality of vertical members and a plurality of horizontal members are crossed and assembled, the contact area with the colliding animal is small, and the friction coefficient with the animal is small. This makes it easier to remove the animal that collided with the obstruction device out of the track so that it slides along the obstruction device.
In particular, since the cross members extending in the left-right direction in the front view are assembled so as to be arranged on the front side of the vertical members, it becomes easy for the animal that collided with the obstruction device to slide along the plurality of cross members. Therefore, it is possible to preferably guide the animals that collide with the obstruction device to be excluded from the track.

また、格子形状を有している排障器であれば、雪を通過させることができる隙間を有する構造であるので、この排障器が除雪板よりも進行方向前方に取り付けられていても、除雪板による除雪の妨げにはならない。つまり、この排障器であれば、鉄道車両に取り付けられている除雪板と好適に併用することができるので、降雪地域を走行する鉄道車両に取り付けて使用することができる。 Further, if the obstacle remover has a grid shape, it has a structure having a gap through which snow can pass, so even if the obstacle remover is attached to the front of the snow removal plate in the traveling direction, It does not interfere with snow removal by the snow removal board. That is, since this obstruction device can be suitably used in combination with the snow removal plate attached to the railway vehicle, it can be attached to the railway vehicle traveling in the snowfall area.

なお、板金加工してなる波形板状の排障器であれば、動物の排除が可能であって、従来技術の緩衝材製の排障器よりもコンパクトにすることができるが、除雪板による除雪の妨げになるので好ましくない。 It should be noted that a corrugated plate-shaped obstruction device made by sheet metal processing can eliminate animals and can be made more compact than the obstruction device made of cushioning material of the prior art. It is not preferable because it interferes with snow removal.

また、望ましくは、
前記鉄道車両の妻面の下部中央側には連結器が配設されており、
当該排障器は、前記連結器を挟む配置に対を成して取り付けられているようにする。
降雪地域を走行する鉄道車両は、例えば牽引用の車両に連結されて走行することがあるので、連結器を挟む配置に一対の排障器を取り付けて、常に連結器を使用可能に露出させるようにした。 Also, preferably
A coupler is arranged on the lower center side of the end surface of the railway vehicle.
The obstruction device shall be attached in pairs in an arrangement that sandwiches the coupler.
Since railcars traveling in snowy areas may be connected to, for example, a towing vehicle, a pair of obstacles should be attached to sandwich the coupler so that the coupler is always exposed so that it can be used. I made it.

また、望ましくは、
前記縦材は、下端側よりも上端側の方が進行方向後方に下がるように傾斜した姿勢を有するようにする。
こうすることで、排障器に衝突した動物を車両下に巻き込まないようにすくい上げるように誘導しつつ、線路外へ排除する誘導を行うことができる。 Also, preferably
The vertical member has an inclined posture so that the upper end side is lowered backward in the traveling direction rather than the lower end side.
By doing so, it is possible to guide the animal that has collided with the obstruction device to be scooped up so as not to get caught under the vehicle, and to exclude the animal from the track.

また、望ましくは、
前記横材は、前記鉄道車両の幅方向中央側の端部よりも車両側面側の端部の方が進行方向後方に下がるように傾斜した姿勢を有するようにする。
こうすることで、排障器に衝突した動物を車両側面側に誘導して線路外へ排除することができる。 Also, preferably
The cross member shall have an inclined posture so that the end portion on the side surface side of the vehicle is lowered rearward in the traveling direction than the end portion on the center side in the width direction of the railway vehicle .
By doing so, the animal that collided with the obstruction device can be guided to the side surface of the vehicle and excluded from the track.

本発明によれば、鉄道車両に取り付けられている除雪板と好適に併用することができる排障器が得られる。 According to the present invention, it is possible to obtain an obstruction device that can be suitably used in combination with a snow removal plate attached to a railway vehicle.

以下、図面を参照して、本発明に係る排障器の実施形態について詳細に説明する。但し、以下に述べる実施形態には、本発明を実施するために技術的に好ましい種々の限定が付されているが、本発明の範囲を以下の実施形態及び図示例に限定するものではない。
鉄道車両に取り付けて使用される排障器は、走行中の鉄道車両の前面（妻面）に衝突した動物を車両下に巻き込まないように線路外へ排除する機能を有している。
なお、排障器は、先頭車両の前面（妻面）、換言すれば、車両進行方向の前面（妻面）に取り付けて使用される。 Hereinafter, embodiments of the obstruction device according to the present invention will be described in detail with reference to the drawings. However, although the embodiments described below are provided with various technically preferable limitations for carrying out the present invention, the scope of the present invention is not limited to the following embodiments and illustrated examples.
The obstruction device used by being attached to a railroad vehicle has a function of removing an animal that has collided with the front surface (wife surface) of the running railroad vehicle from the railroad track so as not to get caught under the vehicle.
The obstruction device is used by being attached to the front surface (wife surface) of the leading vehicle, in other words, the front surface (wife surface) in the vehicle traveling direction.

本実施形態の排障器１００は、図１〜図３に示すように、鉄道車両Ｔの妻面の下部に配設されている除雪板Ｐよりも進行方向の前側に位置するように、鉄道車両Ｔに取り付けられている。
つまり、本実施形態の排障器１００は、除雪板Ｐを備えて降雪地域を走行可能にした仕様の鉄道車両Ｔに取り付けて使用される。 As shown in FIGS. 1 to 3, the obstruction device 100 of the present embodiment is located on the front side in the traveling direction with respect to the snow removal plate P arranged at the lower part of the end surface of the railway vehicle T. It is attached to the vehicle T.
That is, the obstruction device 100 of the present embodiment is used by being attached to a railroad vehicle T having a snow removal plate P and capable of traveling in a snowfall area.

また、鉄道車両Ｔの妻面の下部中央側には連結器Ｒが配設されており、その連結器Ｒを挟む配置に排障器１００が対を成して取り付けられている。
なお、連結器Ｒの構成や動作は従来公知のものと同様であるので、ここでは詳述しない。 Further, a coupler R is arranged on the lower center side of the end surface of the railroad vehicle T, and obstruction devices 100 are attached in pairs in an arrangement sandwiching the coupler R.
Since the configuration and operation of the coupler R are the same as those conventionally known, they will not be described in detail here.

この排障器１００は、図１〜図３に示すように、正面視上下方向に延在する複数の縦材１０と、正面視左右方向に延在する複数の横材２０を備えており、その縦材１０と横材２０とが交差してなる格子形状を有している。
縦材１０と横材２０はどちらも金属製の棒状部材あるいは管状部材であり、縦材１０と横材２０とが交差する箇所で溶接されて、縦材１０と横材２０とが一体に組み付けられている。
特に、横材２０は縦材１０の前面側に配されるように組み付けられている。 As shown in FIGS. 1 to 3, the obstruction device 100 includes a plurality of vertical members 10 extending in the vertical direction in the front view and a plurality of horizontal members 20 extending in the horizontal direction in the front view. It has a lattice shape in which the vertical member 10 and the horizontal member 20 intersect.
Both the vertical member 10 and the horizontal member 20 are metal rod-shaped members or tubular members, and are welded at the intersection of the vertical member 10 and the horizontal member 20, and the vertical member 10 and the horizontal member 20 are integrally assembled. Has been done.
In particular, the horizontal member 20 is assembled so as to be arranged on the front side of the vertical member 10.

縦材１０は、図２（ａ）に示すように、下端側よりも上端側の方が進行方向後方に下がるように傾斜した姿勢を有している。本実施形態の縦材１０は垂直仮想線Ｌ１に対し、θ１の角度を成している。この角度θ１は例えば８°であることが好ましい。
また、縦材１０は下端部分と上端部分とで折曲されており、それぞれの端部は鉄道車両Ｔの後方に延在して排障器支持部３０に固設されている。 As shown in FIG. 2A, the vertical member 10 has an inclined posture so that the upper end side is lowered rearward in the traveling direction rather than the lower end side. The vertical member 10 of the present embodiment forms an angle of θ1 with respect to the vertical virtual line L1. The angle θ1 is preferably, for example, 8 °.
Further, the vertical member 10 is bent at the lower end portion and the upper end portion, and each end portion extends to the rear of the railway vehicle T and is fixed to the obstruction device support portion 30.

横材２０は、図２（ｂ）に示すように、車両の幅方向中央側の連結器Ｒ寄りの端部よりも車両側面側の端部の方が進行方向後方に下がるように傾斜した姿勢を有している。本実施形態の横材２０は車両長手方向と直交する水平仮想線Ｌ２に対し、θ２の角度を成している。この角度θ２は例えば２０°であることが好ましい。
また、横材２０は左右両端部分で折曲されており、それぞれの端部は鉄道車両Ｔの後方に延在して排障器支持部３０に固設されている。 As shown in FIG. 2B, the cross member 20 has an inclined posture so that the end portion on the side surface side of the vehicle is lowered rearward in the traveling direction rather than the end portion closer to the coupler R on the center side in the width direction of the vehicle. have. The cross member 20 of the present embodiment forms an angle of θ2 with respect to the horizontal virtual line L2 orthogonal to the longitudinal direction of the vehicle. The angle θ2 is preferably, for example, 20 °.
Further, the cross member 20 is bent at both left and right ends, and each end extends to the rear of the railway vehicle T and is fixed to the obstruction device support portion 30.

排障器支持部３０は金属製の部材であり、この排障器支持部３０を鉄道車両Ｔの台枠（図示省略）にボルトやナットなどの締結具を用いて固定することで、排障器１００を鉄道車両Ｔに取り付けることができる。
なお、除雪板Ｐと連結器Ｒも鉄道車両Ｔの台枠（図示省略）に固定されている。 The obstruction device support portion 30 is a metal member, and the obstruction device support portion 30 is fixed to the underframe (not shown) of the railway vehicle T by using fasteners such as bolts and nuts to eliminate obstacles. The vessel 100 can be attached to the railroad vehicle T.
The snow removal plate P and the coupler R are also fixed to the underframe (not shown) of the railway vehicle T.

このように、本実施形態の排障器１００は、複数の縦材１０と複数の横材２０とを交差させて組み付けた格子形状を有しており、雪を通過させることができる隙間を有する構造であるので、この排障器１００が除雪板Ｐよりも進行方向前方に取り付けられていても、除雪板Ｐによる除雪の妨げにはならない。
また、格子状の排障器１００には雪は積もり難く、積もっても落雪し易い構造であるので、雪の重みで排障器１００が変形するようなトラブルは発生しない。
つまり、この排障器１００は、除雪板Ｐと好適に併用することができるので、降雪地域を走行する鉄道車両Ｔに取り付けて使用することができる。 As described above, the obstruction device 100 of the present embodiment has a lattice shape in which a plurality of vertical members 10 and a plurality of horizontal members 20 are crossed and assembled, and has a gap through which snow can pass. Due to the structure, even if the obstruction device 100 is attached to the front of the snow removal plate P in the traveling direction, it does not hinder the snow removal by the snow removal plate P.
Further, since the lattice-shaped obstruction device 100 has a structure in which snow is difficult to accumulate and snow falls easily even if it is accumulated, trouble that the obstruction device 100 is deformed by the weight of the snow does not occur.
That is, since the obstruction device 100 can be suitably used in combination with the snow removal plate P, it can be used by being attached to a railroad vehicle T traveling in a snowfall area.

また、降雪地域を走行する鉄道車両Ｔは、例えば牽引車に連結されて走行することがある。
そのため、鉄道車両Ｔの妻面に配設されている連結器Ｒによる牽引車との連結動作を妨げない位置に、排障器１００を取り付けなければならない。
そこで、連結器Ｒを挟む配置に一対の排障器１００を取り付けて、常に連結器Ｒを使用可能に露出させるようにした。
このような排障器１００であれば、降雪地域を走行する鉄道車両Ｔに取り付けて使用することができる。 Further, the railway vehicle T traveling in the snowfall area may travel by being connected to, for example, a towing vehicle.
Therefore, the obstruction device 100 must be installed at a position that does not interfere with the coupling operation with the towing vehicle by the coupler R arranged on the end surface of the railway vehicle T.
Therefore, a pair of obstruction devices 100 were attached in an arrangement sandwiching the coupler R so that the coupler R was always exposed so as to be usable.
Such an obstruction device 100 can be used by being attached to a railroad vehicle T traveling in a snowfall area.

また、本実施形態の排障器１００は、複数の縦材１０と複数の横材２０とを交差させて組み付けた格子形状を有しているので、衝突した動物との接触面積が小さく、その動物との摩擦係数を小さくすることができる。
衝突した動物と排障器１００との摩擦係数が小さければ、排障器１００に衝突した動物を排障器１００に沿って滑らせるように線路外へ排除し易くなる。
特に、横材２０が縦材１０の前面側に配されるように組み付けられているので、排障器１００に衝突した動物を複数の横材２０に沿って滑らせ易くなっており、排障器１００に衝突した動物を線路外へ排除する誘導を好適に行うことができる。
更に、横材２０は、車両の幅方向中央側の端部よりも車両側面側の端部の方が進行方向後方に下がるように傾斜した姿勢を有しているので、排障器１００に衝突した動物を複数の横材２０に沿って滑らせて線路外へ排除する誘導をより好適に行うことができる。 Further, since the obstruction device 100 of the present embodiment has a lattice shape in which a plurality of vertical members 10 and a plurality of horizontal members 20 are crossed and assembled, the contact area with the colliding animal is small, and the contact area thereof is small. The coefficient of friction with animals can be reduced.
If the coefficient of friction between the colliding animal and the obstruction device 100 is small, the animal that collides with the obstruction device 100 can be easily excluded from the track so as to slide along the obstruction device 100.
In particular, since the cross member 20 is assembled so as to be arranged on the front side of the vertical member 10, it is easy for the animal colliding with the obstruction device 100 to slide along the plurality of cross members 20, and the obstruction is eliminated. Guidance to eliminate the animal colliding with the vessel 100 out of the track can be preferably performed.
Further, since the cross member 20 has an inclined posture so that the end portion on the side surface side of the vehicle is lowered rearward in the traveling direction than the end portion on the central side in the width direction of the vehicle, the cross member 20 collides with the obstruction device 100. It is possible to more preferably guide the animals to be slid along the plurality of cross members 20 and excluded from the track.

また、排障器１００の縦材１０は、下端側よりも上端側の方が進行方向後方に下がるように傾斜した姿勢を有しているので、排障器１００に衝突した動物を車両下に巻き込まないようにすくい上げるように誘導しつつ、線路外へ排除する誘導を行うことが可能になっている。 Further, since the vertical member 10 of the obstruction device 100 has an inclined posture so that the upper end side is lowered to the rear in the traveling direction rather than the lower end side, the animal colliding with the obstruction device 100 is placed under the vehicle. It is possible to guide the car to scoop it up so that it does not get caught, and to guide it to the outside of the track.

ところで、都電荒川線にも格子状の排障器が取り付けられることがあるが、この排障器の前面部には傾斜（角度）が設けられていない。この排障器は、車両下に支障物を巻き込まないために取り付けられたものであり、比較的速度を上げずに走行する都電荒川線が、排障器で支障物を線路外へ排除するように誘導するという目的はない。
これに対し、本実施形態の排障器１００は、６０〜８０［ｋｍ／ｈ］で走行する車両に取り付けられ、排障器１００に衝突した動物を線路外へ排除する誘導を行うことができ、都電荒川線の排障器とは異なる格別の効果を有している。 By the way, a grid-like obstruction device may be attached to the Toden-Arakawa Line, but the front portion of the obstruction device is not provided with an inclination (angle). This obstruction device is installed to prevent obstacles from getting caught under the vehicle, so that the Toden-Arakawa Line, which runs at a relatively low speed, removes obstructions from the track with the obstruction device. There is no purpose to induce to.
On the other hand, the obstruction device 100 of the present embodiment is attached to a vehicle traveling at 60 to 80 [km / h], and can guide the animal that collides with the obstruction device 100 to be excluded from the track. , It has a special effect different from the obstruction device of the Toden-Arakawa line.

以上のように、本実施形態の排障器１００は、衝突した動物を複数の横材２０に沿って滑らせて線路外へ排除する誘導を好適に行うことができる。
そして、この排障器１００は、雪を通過させることができる隙間を有する格子構造であるため、排障器１００が除雪板Ｐよりも進行方向前方に取り付けられていても、除雪板Ｐによる除雪の妨げにはならないので、鉄道車両Ｔに取り付けられている除雪板Ｐと好適に併用することができる。 As described above, the obstruction device 100 of the present embodiment can preferably guide the colliding animal by sliding it along the plurality of cross members 20 and excluding it from the track.
Since the obstacle 100 has a lattice structure having a gap through which snow can pass, even if the obstacle 100 is attached to the front of the snow removal plate P in the traveling direction, the snow removal plate P removes snow. Since it does not interfere with the snow removal plate P, it can be suitably used in combination with the snow removal plate P attached to the railway vehicle T.

なお、以上の実施の形態においては、縦材１０と横材２０とが交差する箇所で溶接されて組み付けられているとしたが、本発明はこれに限定されるものではなく、例えば、ボルトやナットなどの締結具を用いて縦材１０と横材２０を組み付けるなどしてもよい。
In the above embodiment, it is assumed that the vertical member 10 and the horizontal member 20 are welded and assembled at the intersection, but the present invention is not limited to this, and for example, bolts and bolts are used. The vertical member 10 and the horizontal member 20 may be assembled using a fastener such as a nut.

また、その他、具体的な細部構造等についても適宜に変更可能であることは勿論である。 In addition, it goes without saying that the specific detailed structure and the like can be changed as appropriate.
