Description

本発明は、地上子取付台に係り、特に、軌道上に固定される地上子を軌道に取り付けるための地上子取付台に関する。   The present invention relates to a ground unit mounting base, and more particularly to a ground unit mounting base for mounting a ground unit fixed on a track to the track.

自動列車制御装置（ＡＴＣ：Automatic Train Control）や自動列車運転装置（ＡＴＯ：Automatic Train Operation）、地点検知等における列車と線路上の通信は、列車に装備された車上子と、図１０に示すような軌道上に固定された地上子Ａを介して行われる。地上子Ａは、通常、図示しないアンテナや電子部品が内蔵されて略平板状に形成され（例えば特許文献１等参照）、軌道Ｌ上に設置された地上子取付台１００に下方から支持された状態に取り付けられて配置されるようになっている。   Communication on the train and track in automatic train control (ATC), automatic train operation (ATO), point detection, etc. is shown in FIG. This is performed through the ground element A fixed on the orbit. The ground unit A is generally formed in a substantially flat plate shape with built-in antennas and electronic parts (not shown) (see, for example, Patent Document 1) and supported from below on the ground unit mounting base 100 installed on the track L. It is arranged to be attached to the state.

地上子取付台１００は、通常、図１１に示すように、軌道Ｌのスラブ等に固定されたアンカーボルトＢを取付孔１０１に挿通してナットＮ等で締め付けて固定されて軌道Ｌ上に設置されるようになっている。そして、地上子Ａは、上下に貫通する取付孔Ａｈが、地上子取付台１００の上部の取付部１０２に設けられた取付孔１０３に位置合わせされた状態で挿通されたボルト１０４とナット１０５を締結することで地上子取付台１００に取り付けられるようになっている。
特開平１１−２５８３３０号公報 As shown in FIG. 11, the ground support mounting base 100 is usually installed on the track L by being fastened with an anchor bolt B fixed to a slab or the like of the track L through the mounting hole 101 and tightened with a nut N or the like. It has come to be. The ground element A includes a bolt 104 and a nut 105 inserted in a state in which the mounting hole Ah penetrating vertically is aligned with the mounting hole 103 provided in the mounting part 102 on the upper part of the ground element mounting base 100. By being fastened, it can be attached to the ground unit mounting base 100.
JP 11-258330 A

ところで、例えば、東北新幹線等では、東北地方で降雪時に軌道上に積もった雪などが列車の進行により巻き上げられて列車の下部に付着し、それが堆積して成長し、列車が軌道Ｌ上を進行して関東地方に入って気温が高くなるなどすると、今度は列車の下部に堆積して成長した雪の塊やそれらの雪が固まって形成された氷の塊が列車の下部から軌道Ｌ上に脱落する場合がある。   By the way, in the Tohoku Shinkansen, for example, snow that has accumulated on the track during the snowfall in the Tohoku region is rolled up by the train and adheres to the lower part of the train, and it accumulates and grows. As the weather progresses and enters the Kanto region and the temperature rises, the snow mass that has accumulated and grown in the lower part of the train and the ice mass formed by the solidification of the snow are now on the track L from the lower part of the train. May fall off.

落下した雪や氷の大きな塊は、少なくとも落下当初は軌道Ｌの静止面に対して列車の速度と同程度の大きな速度を有しており、軌道Ｌ上を滑っていって、軌道Ｌ上に設置された地上子Ａや地上子取付台１００に衝突する場合がある。   A large lump of snow or ice that has fallen has a speed that is about the same as the speed of the train with respect to the stationary surface of the track L at least at the beginning of the fall. There is a case where it collides with the installed ground unit A or the ground unit mounting base 100.

従来の地上子Ａは、図１０に矢印Ｐで示した進行方向に進行してくる列車から見て、その手前側の端面Ａａが、地上子取付台１００の手前側の壁面１０６よりも手前側に張り出すように取り付けられる。したがって、図１０の矢印Ｐの方向に軌道Ｌ上を滑ってきた雪や氷の塊が地上子Ａの端面ａに大きな速度を有する状態で衝突するため、地上子Ａが破壊されてしまう事態が生じていた。   The conventional ground element A is viewed from the train traveling in the traveling direction indicated by the arrow P in FIG. 10, and the end face Aa on the near side is closer to the near side than the wall surface 106 on the near side of the ground element mounting base 100. It is attached to overhang. Therefore, since a lump of snow or ice that has slid on the track L in the direction of the arrow P in FIG. 10 collides with the end surface a of the ground element A with a large speed, the ground element A is destroyed. It was happening.

この点について、例えば、地上子Ａの手前側に防護用の鉄板等を置く等の方法が考えられるが、金属製の防護板を地上子Ａの近傍に置くと地上子Ａ内のアンテナの送受信の特性に悪影響を及ぼす等の問題があり、採用し難い。   Regarding this point, for example, a method of placing a protective iron plate or the like on the front side of the ground element A is conceivable. However, if a metal protective plate is placed in the vicinity of the ground element A, antenna transmission / reception within the ground element A is possible. There are problems such as adversely affecting the characteristics of the product, making it difficult to adopt.

また、特許文献１に記載された地上子では、地上子Ａの上方から飛来する落下物等の衝撃には有効であると考えられる。しかし、列車の下部に堆積した雪や氷の塊が地上子Ａの上面Ａｂに落下する確率は低い。そのうえ、落下しても列車の下部と地上子Ａの上面Ａｂの高さはさほど差がないため、地上子Ａの上面Ａｂに加わる衝撃は大きくなく、通常、地上子Ａの上面Ａｂに落下しても地上子Ａを破壊するほどの被害にはならない。   Moreover, it is thought that the ground element described in Patent Document 1 is effective for the impact of falling objects and the like flying from above the ground element A. However, there is a low probability that snow or ice blocks deposited on the lower part of the train will fall on the upper surface Ab of the ground element A. In addition, since the height of the lower surface of the train and the upper surface Ab of the ground child A does not differ much even if it falls, the impact applied to the upper surface Ab of the ground child A is not large, and usually falls on the upper surface Ab of the ground child A. But it won't cause enough damage to destroy ground child A.

このように、列車から脱落し、軌道Ｌ上を滑走して地上子Ａに横方向、特に列車の進行方向から衝突する雪や氷の大きな塊のように、地上子Ａに横方向から衝突する物体に対しては、特許文献１に記載された地上子の構成は必ずしも有効とは言い難い。また、特許文献１に記載された地上子は特殊な構成のものであり、それ自体安価なものとは言い難く、既設の地上子Ａをこの地上子に置き換えるには多額の費用を要するという問題もある。   In this way, it falls off the train, slides on the track L, and collides with the ground element A from the lateral direction, like a large lump of snow or ice that collides with the ground element A, particularly from the traveling direction of the train. For an object, the configuration of the ground unit described in Patent Document 1 is not necessarily effective. In addition, the ground element described in Patent Document 1 has a special configuration, and it is difficult to say that the ground element itself is inexpensive, and a problem that a large amount of money is required to replace the existing ground element A with this ground element. There is also.

そこで、本発明は、列車の進行方向の手前側から接近する雪や氷の塊等の物体の衝撃から地上子を防護し、地上子の破壊を防止することが可能な地上子取付台を提供することを目的とする。また、従来の地上子取付台と安価に交換し得る地上子取付台を提供することも目的とする。   Therefore, the present invention provides a ground unit mounting base capable of protecting the ground unit from the impact of an object such as snow or a lump of ice approaching from the front side of the traveling direction of the train and preventing the ground unit from being destroyed. The purpose is to do. It is another object of the present invention to provide a ground unit mounting base that can be exchanged with a conventional ground base mounting base at a low cost.

A second extending portion is provided extending from the end surface on the same side of the child, and the second extending portion is formed in the same shape as the extending portion.

請求項１に記載の発明によれば、もともと地上子取付台は地上子Ａのアンテナの送受信特性に悪影響を及ぼさないように金属を含まない強化プラスチック等で形成されるが、その手前側の壁面を地上子Ａの手前側の端面Ａａよりも手前側に延設して延設部を設けたため、地上子Ａのアンテナの送受信特性に悪影響を及ぼすことなく、軌道Ｌ上を滑走してきた雪や氷の塊等の物体を地上子Ａではなく地上子取付台の延設部に衝突させることが可能となる。そのため、延設部により地上子Ａを防護することが可能となり、地上子Ａが物体と衝突して破壊されることを防止することが可能となる。   According to the first aspect of the present invention, the ground element mounting base is originally formed of a reinforced plastic that does not contain metal so as not to adversely affect the transmission / reception characteristics of the antenna of the ground element A. Is extended to the front side of the end surface Aa on the near side of the ground element A and provided with an extending portion, so that the snow or the snow that has slid on the track L without adversely affecting the transmission / reception characteristics of the antenna of the ground element A An object such as an ice lump can be made to collide with the extended portion of the ground unit mount instead of the ground unit A. Therefore, it is possible to protect the ground element A by the extending portion, and it is possible to prevent the ground element A from colliding with an object and being destroyed.

また、軌道のスラブ等に固定されたアンカーボルトＢに対する地上子取付台の取付孔の位置を、前述した従来の地上子取付台１００を固定するための複数のアンカーボルトＢの位置に対応する位置に設け、地上子Ａを取り付けるための取付部を、もともと従来の地上子取付台１００に取り付けられていた地上子Ａの取付孔Ａｈに対応する位置に設けるように構成すれば、従来の地上子取付台１００を本発明に係る地上子取付台に取り替える際に、もともとのアンカーボルトＢや地上子Ａをそのまま使うことができる。   Further, the position of the mounting hole of the ground unit mounting base with respect to the anchor bolt B fixed to the slab of the track corresponds to the position of the plurality of anchor bolts B for fixing the conventional ground base mounting base 100 described above. If the mounting portion for mounting the ground unit A is provided at a position corresponding to the mounting hole Ah of the ground unit A originally mounted on the conventional ground unit mounting base 100, the conventional ground unit When replacing the mounting base 100 with the ground unit mounting base according to the present invention, the original anchor bolt B or ground unit A can be used as it is.

Since it is only necessary to replace the ground unit mounting base, it is possible to replace the conventional ground base mounting base 100 with the ground base mounting base according to the present invention at low cost.

さらに、延設部の手前側の壁面の左右方向の略中央部分を手前側に突出させて楔状に形成することで、延設部の中央部分に衝突する物体を破壊し、また、左右の傾斜面に衝突した物体を左右方向に弾き跳ばすことが可能となる。そのため、延設部や地上子取付台が物体の運動エネルギを真正面から受け止めて地上子取付台がアンカーボルトＢからはずれてしまうことが防止され、地上子Ａの設置位置を維持することが可能となる。   Furthermore, the substantially central part in the left-right direction of the wall surface on the near side of the extension part is formed in a wedge shape by projecting to the near side, thereby destroying the object that collides with the center part of the extension part, and also tilting left and right It is possible to bounce off an object colliding with the surface in the left-right direction. Therefore, it is possible to prevent the extension unit and the ground unit mounting base from receiving the kinetic energy of the object from the front and the ground base mounting base from being detached from the anchor bolt B, and to maintain the installation position of the ground unit A. Become.

請求項２に記載の発明によれば、前記発明と同様に、地上子取付台の手前側の壁面を地上子Ａの手前側の端面Ａａよりも手前側に延設して延設部を設けたため、地上子Ａのアンテナの送受信特性に悪影響を及ぼすことなく、軌道Ｌ上を滑走してきた雪や氷の塊等の物体を地上子Ａではなく地上子取付台の延設部に衝突させることが可能となる。そのため、延設部により地上子Ａを防護することが可能となり、地上子Ａが物体と衝突して破壊されることを防止することが可能となる。   According to the second aspect of the present invention, as in the case of the above-described invention, the wall surface on the near side of the ground element mounting base is extended to the near side with respect to the end surface Aa on the near side of the ground element A to provide the extending portion. For this reason, an object such as a snow or a lump of ice that has slid on the track L does not collide with the extended portion of the ground unit mounting base but the ground unit A without adversely affecting the transmission / reception characteristics of the antenna of the ground unit A. Is possible. Therefore, it is possible to protect the ground element A by the extending portion, and it is possible to prevent the ground element A from colliding with an object and being destroyed.

また、アンカーボルトＢに対する地上子取付台の取付孔の位置を従来の地上子取付台１００を固定するための複数のアンカーボルトＢの位置に対応する位置に設け、地上子Ａを取り付けるための取付部を従来の地上子取付台１００に取り付けられていた地上子Ａの取付孔Ａｈに対応する位置に設けるように構成すれば、従来の地上子取付台１００を本発明に係る地上子取付台に取り替える際に、もともとのアンカーボルトＢや地上子Ａをそのまま使うことができる。   Also, the mounting holes for mounting the ground element A are provided at positions corresponding to the positions of the plurality of anchor bolts B for fixing the conventional ground element mounting base 100 with respect to the anchor bolt B. If the portion is provided at a position corresponding to the mounting hole Ah of the ground unit A that is mounted on the conventional ground unit mounting base 100, the conventional ground unit mounting base 100 according to the present invention is used as the ground unit mounting base. When replacing, the original anchor bolt B and ground element A can be used as they are.

また、延設部の手前側の壁面の左右方向の一端部を手前側に突出させて壁面を左右方向に傾斜させることで、延設部の壁面に衝突する物体を左右いずれかの方向に弾き跳ばすことが可能となる。そのため、延設部や地上子取付台が物体の運動エネルギを真正面から受け止めて地上子取付台がアンカーボルトＢからはずれてしまうことが防止され、地上子Ａの設置位置を維持することが可能となる。   In addition, by projecting an object that collides with the wall surface of the extension part in either the left or right direction by projecting one end part of the wall surface on the near side of the extension part toward the front side and inclining the wall surface in the left or right direction, It is possible to jump. Therefore, it is possible to prevent the extension unit and the ground unit mounting base from receiving the kinetic energy of the object from the front and the ground base mounting base from being detached from the anchor bolt B, and to maintain the installation position of the ground unit A. Become.

請求項３に記載の発明によれば、延設部の左右方向の一端部または両端部を奥側に延出することで、延設部の延出部分により、左右方向から飛んでくる物体や延設部に衝突して破壊された物体の破片等が地上子Ａの側方の端面に衝突して地上子Ａが損傷することを防止することが可能となり、前記各発明の効果がより的確に発揮される。   According to the invention described in claim 3, by extending one end or both ends in the left-right direction of the extending portion to the back side, an object flying from the left-right direction by the extending portion of the extending portion, It is possible to prevent debris or the like of an object that has been destroyed by colliding with the extended portion from colliding with the side end surface of the ground element A and damaging the ground element A, and the effects of the above-described inventions can be more accurately achieved. To be demonstrated.

請求項４に記載の発明によれば、前記各発明の効果に加え、延設部と反対側に延設部と同形の第二延設部を設けることで、地上子取付台の進行方向手前側と奥側の重量バランスが良好になり、列車の進行等で軌道が振動した場合の地上子取付台の共振が難くなり、地上子取付台の経時的な損傷や破壊の頻度を低減することが可能となる。また、進行方向奥側から物体が飛来等してくる場合にも地上子Ａを防護することが可能となる。また、第二延設部を延設部と同形に形成することで、地上子取付台の軌道への取り付け方向の制限がなくなる。   According to the fourth aspect of the present invention, in addition to the effects of the above-described inventions, the second extension part having the same shape as the extension part is provided on the side opposite to the extension part, so that the ground element mounting base is in front of the traveling direction. The weight balance between the side and the back will be good, and the ground unit mount will not resonate when the track vibrates due to the traveling of the train, etc., and the frequency of damage and destruction of the ground unit will be reduced over time. Is possible. Further, the ground child A can be protected even when an object comes from the back side in the traveling direction. Further, by forming the second extending portion in the same shape as the extending portion, there is no restriction on the mounting direction of the ground unit mounting base on the track.

以下、本発明に係る地上子取付台の実施の形態について、図面を参照して説明する。   DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, embodiments of a ground unit mounting base according to the present invention will be described with reference to the drawings.

An extending portion 3 is provided so as to extend to the side.

地上子取付台１の本体部２は、基本的に従来の地上子取付台１００と同様に構成されており、本体部２の底面には、図１１に示した従来の地上子取付台１００を固定するための複数のアンカーボルトＢに対応する位置に取付孔４がそれぞれ穿設されている。また、本体部２の側壁５の上部には、地上子Ａを取り付けるための取付部６が側壁５から左右方向外側に張り出すように設けられている。各取付部６には、図１１に示した地上子Ａの取付孔Ａｈに対応する位置にそれぞれ取付孔７が上下方向に穿設されている。   The body unit 2 of the ground unit mounting base 1 is basically configured in the same manner as the conventional ground unit mounting base 100, and the conventional ground unit mounting base 100 shown in FIG.

In the present embodiment, among the mounting portions 6 of the main body 2 described above, the mounting portion 6a on the front side has a shape protruding outward from the side wall 5 in the left-right direction to the back surface 9 of the extending portion 3 on the front side. It is formed continuously.

延設部３は、本実施形態では、進行方向Ｐから見た場合に、その手前側の壁面８の左右方向の中央部分８１が手前側に突出し、そこから左右方向に離れるに従って進行方向Ｐに沿って奥側に遠ざかるように傾斜した楔状に形成されている。なお、以下、延設部３の手前側の壁面８の左右の二面を区別して言う場合、進行方向Ｐから見て右側の壁面８を壁面８２、左側の壁面８を壁面８３という。また、上記の中央部分８１は、必ずしも正確に壁面８の左右方向の中央に設けられる必要はない。   In the present embodiment, when viewed from the advancing direction P, the extending portion 3 projects in the advancing direction P as the center portion 81 in the left-right direction of the wall surface 8 on the near side protrudes toward the front side and moves away from it in the left-right direction. It is formed in the shape of a wedge inclined so as to move away from the back side. In the following description, when the left and right surfaces of the wall surface 8 on the near side of the extending portion 3 are distinguished from each other, the right wall surface 8 is referred to as a wall surface 82 and the left wall surface 8 is referred to as a wall surface 83 when viewed from the traveling direction P. Further, the central portion 81 does not necessarily need to be accurately provided at the center in the left-right direction of the wall surface 8.

本実施形態では、延設部３は、地上子取付台１の本体部２と一体成形されており、例えばガラス繊維強化プラスチック（ＦＲＰ：Fiber Reinforced Plastics）等のガラス繊維とエポキシ樹脂とを含む材料で形成されている。また、延設部３の内部には空洞部分は形成されておらず、延設部３は中実状に形成されている。   In the present embodiment, the extending portion 3 is integrally formed with the main body portion 2 of the ground unit mounting base 1, for example, a material containing glass fiber such as glass fiber reinforced plastic (FRP) and epoxy resin. It is formed with. Moreover, the hollow part is not formed in the extension part 3, but the extension part 3 is formed in the solid shape.

地上子取付台１は、図２に示すように、軌道Ｌのスラブ等に固定されたアンカーボルトＢを本体部２の取付孔４に挿通してナットＮ等で締め付けて固定されて軌道Ｌ上に設置されるようになっている。また、本体部２の取付部６には、取付部６の取付孔７と地上子Ａの取付孔Ａｈとが位置合わせされた状態で地上子Ａが載置される。そして、取付部６の取付孔７と地上子Ａの取付孔Ａｈに挿通されたボルト１０とナット１１を締結することで、地上子取付台１に地上子Ａが取り付けられるようになっている。   As shown in FIG. 2, the ground mount mounting base 1 is fixed on the track L by inserting an anchor bolt B fixed to a slab or the like of the track L through the mounting hole 4 of the main body 2 and tightening with a nut N or the like. It is supposed to be installed in. The ground element A is placed on the attachment part 6 of the main body 2 in a state where the attachment hole 7 of the attachment part 6 and the attachment hole Ah of the ground element A are aligned. Then, the ground element A is attached to the ground element mounting base 1 by fastening the bolt 10 and the nut 11 inserted into the attachment hole 7 of the attachment part 6 and the attachment hole Ah of the ground element A.

その際、アンカーボルトＢとしては、図１１に示した従来の地上子取付台１００を固定する場合と全く同様に配置されたものを用いることができる。また、地上子Ａとしては、従来の地上子取付台１００に取り付ける場合と全く同じ位置に取付孔Ａｈが設けられた地上子Ａを用いることができる。   At this time, as the anchor bolt B, a bolt arranged in the same manner as in the case of fixing the conventional ground element mounting base 100 shown in FIG. 11 can be used. Moreover, as the ground element A, the ground element A in which the attachment hole Ah is provided at the same position as the case where it is attached to the conventional ground element mounting base 100 can be used.

地上子Ａが取り付けられた地上子取付台１の斜視図を図３（Ａ）に、側面図を図３（Ｂ）示す。図３（Ｂ）においては、図中左側が進行方向Ｐの手前側であり、右側が進行方向Ｐの奥側となる。   FIG. 3A is a perspective view of the ground unit mounting base 1 to which the ground unit A is mounted, and FIG. 3B is a side view. In FIG. 3B, the left side in the figure is the front side in the traveling direction P, and the right side is the back side in the traveling direction P.

図３に示すように、地上子取付台１の延設部３は、その手前側の壁面８が地上子Ａａの手前側の端面Ａａよりもさらに手前側に位置するように延設されて形成されているが、本実施形態では、さらに、延設部３は、地上子Ａの上面Ａｂと面一または上面Ａｂを越えない高さになるようにその上部１２が本体部２に対して上方に盛り上げて形成されている。また、延設部３の上方に盛り上げられた上部１２と、地上子Ａの手前側の端面Ａａとの間には、間隙Ｇが設けられている。   As shown in FIG. 3, the extending portion 3 of the ground unit mounting base 1 is formed so as to extend so that the near-side wall surface 8 is located on the near side of the near-side end surface Aa of the ground unit Aa. However, in this embodiment, the extension portion 3 further has an upper portion 12 above the main body portion 2 so as to be flush with the upper surface Ab of the ground element A or not to exceed the upper surface Ab. It is formed by raising. Further, a gap G is provided between the upper portion 12 raised above the extended portion 3 and the end surface Aa on the near side of the ground element A.

次に、本実施形態に係る地上子取付台１の作用について説明する。   Next, the operation of the ground unit mount 1 according to the present embodiment will be described.

前述したように、本実施形態では、地上子取付台１の本体部２やそれと一体成形された延設部３とがガラス繊維とエポキシ樹脂とを含む材料で形成されており、金属を含まないため、地上子Ａの近傍に配置されても、地上子Ａ内のアンテナの送受信の特性に悪影響を及ぼすことはない。   As described above, in the present embodiment, the main body portion 2 of the ground unit mounting base 1 and the extending portion 3 integrally formed therewith are formed of a material containing glass fiber and epoxy resin, and do not contain metal. Therefore, even if it is arranged in the vicinity of the ground element A, the antenna transmission / reception characteristics in the ground element A are not adversely affected.

また、軌道Ｌ上を進行する列車の下部に堆積した雪や氷の塊が落下し、軌道Ｌ上を進行方向Ｐにほぼ沿う方向に滑走してくると、本実施形態では、雪や氷の塊は、地上子Ａではなく地上子取付台１の延設部３に衝突する。   In addition, in this embodiment, when snow or ice lumps accumulated on the lower part of the train traveling on the track L fall and slide on the track L in a direction substantially along the traveling direction P, in this embodiment, The lump collides not with the ground element A but with the extension 3 of the ground element mount 1.

その際、例えば図４に示すように、仮に延設部３ａの手前側の壁面８ａが進行方向Ｐに対して直交するように形成されていたとすると、延設部３ａが雪や氷の塊の大きな運動エネルギを真正面から受け止めてしまうため、地上子取付台１ａがアンカーボルトＢからはずれて奥側（すなわち進行方向Ｐの方向）に跳ばされてしまう可能性が高くなる。   At that time, for example, as shown in FIG. 4, if the wall surface 8a on the near side of the extended portion 3a is formed so as to be orthogonal to the traveling direction P, the extended portion 3a is made of snow or ice lump. Since large kinetic energy is received from the front, there is a high possibility that the grounding base 1a is detached from the anchor bolt B and jumped to the back side (that is, in the traveling direction P).

また、例えば図５に示すように、仮に延設部３ｂの手前側の壁面８ｂが進行方向Ｐに対して直交し、かつ下向きに形成されていたとすると、雪や氷の塊が延設部３ｂと衝突すると延設部３ｂの壁面８ｂの下側に潜り込むように作用するため、雪や氷の塊の大きな運動エネルギで地上子取付台１ｂがアンカーボルトＢからはずれて奥側に跳ばされてしまったり、地上子Ａが地上子取付台１ｂごと上方に跳ばされて列車と衝突して破壊されたり列車が故障したりする可能性が高くなる。   Also, for example, as shown in FIG. 5, if the wall surface 8b on the near side of the extending portion 3b is formed perpendicularly to the traveling direction P and downward, a snow or ice lump is formed in the extending portion 3b. When it collides, the ground part mounting base 1b is detached from the anchor bolt B and jumped to the back side due to the large kinetic energy of the snow or ice lump. There is a high possibility that the ground unit A will be jumped upward together with the ground unit mounting base 1b and collide with the train to be destroyed or the train may break down.

さらに、例えば図６に示すように、仮に延設部３ｃの手前側の壁面８ｃが進行方向Ｐに対して直交し、かつ上向きに形成されていたとすると、雪や氷の塊が延設部３ｃと衝突すると延設部３ｃの壁面８ｃで上方に弾き跳ばされるため、雪や氷の塊が列車に衝突して列車を故障させたり、列車の下部に堆積している雪や氷の塊と結合してさらに大きな塊になってしまう可能性が高くなる。また、地上子取付台１ｃがアンカーボルトＢからはずれて奥側に跳ばされてしまう可能性もある。   Furthermore, for example, as shown in FIG. 6, if the wall surface 8c on the near side of the extending portion 3c is formed so as to be orthogonal to the traveling direction P and formed upward, a lump of snow or ice is formed in the extending portion 3c. If it collides with the train, it will bounce upward on the wall surface 8c of the extension part 3c, so that a snow or ice lump collides with the train and breaks down the train, or a snow or ice lump accumulated at the bottom of the train There is a high possibility that they will be combined into larger lumps. Further, there is a possibility that the ground support mounting base 1c may be detached from the anchor bolt B and jumped to the back side.

それに対し、本実施形態のように、延設部３の壁面８の左右方向の中央部分８１を手前側に突出させて壁面８を楔状に形成することで、軌道Ｌ上を滑走してきた雪や氷の塊が延設部３の壁面８の中央部分８１に衝突して破壊されて左右方向に弾き跳ばされたり、右側の壁面８２や左側の壁面８３に衝突して左右方向に弾き跳ばされる。   On the other hand, as in this embodiment, the wall portion 8 is formed in a wedge shape by projecting the central portion 81 in the left-right direction of the wall surface 8 of the extending portion 3 so that the snow A lump of ice collides with the central portion 81 of the wall surface 8 of the extended portion 3 and is destroyed and bounced in the left-right direction, or collides with the right wall surface 82 and the left wall surface 83 and bounces in the left-right direction. .

このように、延設部３を設けたことにより、雪や氷の塊が地上子Ａに直接衝突することが防止される。すなわち、延設部３は、滑走してくる雪や氷の塊から地上子Ａを防護するように機能し、地上子Ａが衝突により破壊されることが防止される。   Thus, the provision of the extending portion 3 prevents the snow or ice lump from directly colliding with the ground element A. That is, the extension part 3 functions to protect the ground element A from the snow and ice blocks that slide, and the ground element A is prevented from being destroyed by the collision.

また、雪や氷の塊がある程度の運動エネルギを持った状態で左右方向に弾かれるため、延設部３が雪や氷の塊の大きな運動エネルギを真正面から受け止めて雪や氷の塊の運動エネルギを延設部３やそれを含む地上子取付台１が吸収してしまうことが防止される。そのため、地上子取付台１がアンカーボルトＢからはずれて奥側に跳ばされてしまうことは防止され、地上子Ａの設置位置が維持される。   In addition, since the snow and ice blocks have a certain amount of kinetic energy, they are flipped left and right, so that the extension part 3 receives the large kinetic energy of the snow and ice blocks from the front and moves the snow and ice blocks. It is prevented that the extension part 3 and the ground element mounting base 1 including the energy absorb energy. Therefore, the ground element mounting base 1 is prevented from being detached from the anchor bolt B and jumped to the back side, and the installation position of the ground element A is maintained.

その際、左右方向に弾き跳ばされた雪や氷の塊が当該軌道Ｌを飛び出して他の軌道Ｌ内に進入しないようにすることが好ましく、弾き跳ばされた雪や氷の塊の運動エネルギをある程度低減させることが好ましい。そのためには、軌道Ｌ上を滑走してきた雪や氷の塊の運動エネルギを延設部３やそれを含む地上子取付台１である程度吸収することが必要となるが、弾き跳ばされた雪や氷の塊の運動エネルギと、延設部３等が吸収するエネルギとの配分は、例えば延設部３の壁面８の左右の壁面８２、８３がなす角度を適宜設定すること等で調整することが可能である。   At that time, it is preferable that the snow or ice mass bounced in the left-right direction jumps out of the track L and does not enter another track L, and the kinetic energy of the bounced snow or ice mass is reduced. It is preferable to reduce to some extent. For this purpose, it is necessary to absorb the kinetic energy of the snow and ice blocks that have been slid on the track L to some extent by the extension portion 3 and the ground element mounting base 1 including the same. The distribution of the kinetic energy of the lump of ice and the energy absorbed by the extension 3 or the like is adjusted, for example, by appropriately setting the angle formed by the left and right wall surfaces 82 and 83 of the wall surface 8 of the extension 3. Is possible.

さらに、延設部３は地上子取付台１の本体部２等とともにガラス繊維とエポキシ樹脂とを含む材料で形成され、しかも、延設部３は中実状に形成されているため、雪や氷の塊が衝突しても延設部３自体が破壊されることはない。   Furthermore, the extension part 3 is formed of a material containing glass fiber and epoxy resin together with the main body part 2 of the ground support base 1 and the extension part 3 is formed in a solid shape. Even if the lump collides, the extension part 3 itself is not destroyed.

また、延設部３の上部１２が本体部２に対して上方に盛り上げられて地上子Ａの手前側の端面Ａａを覆っているため（図３（Ａ）、（Ｂ）等参照）、延設部３の上部１２により雪や氷の塊或いは延設部３の壁面８により破壊された雪や氷の塊が地上子Ａの手前側の端面Ａａ等に衝突することがより確実に防止され、地上子Ａの破壊をより確実に防止することが可能となる。   In addition, since the upper portion 12 of the extension portion 3 is raised upward with respect to the main body portion 2 and covers the end surface Aa on the near side of the ground element A (see FIGS. 3A and 3B), the extension The upper part 12 of the installation part 3 can more reliably prevent the snow or ice mass or the snow or ice mass destroyed by the wall surface 8 of the extension part 3 from colliding with the end face Aa on the near side of the ground element A. Thus, it is possible to more reliably prevent the ground element A from being destroyed.

また、延設部３と地上子Ａａの手前側の端面Ａａとの間に間隙Ｇ（図３（Ａ）、（Ｂ）等参照）が設けられているため、延設部３が雪や氷の塊と衝突した際に多少奥側に移動しても延設部３と地上子Ａとがぶつかることが防止され、地上子Ａの破壊をより確実に防止することが可能となる。   Further, since the gap G (see FIGS. 3A, 3B, etc.) is provided between the extended portion 3 and the end face Aa on the near side of the ground element Aa, the extended portion 3 is made of snow or ice. Even if it moves to the back side to some extent when it collides with the lump, the extension portion 3 and the ground element A are prevented from colliding with each other, and the destruction of the ground element A can be prevented more reliably.

以上のように、本実施形態に係る地上子取付台１によれば、もともと地上子取付台１の本体部２は地上子Ａのアンテナの送受信特性に悪影響を及ぼさないように金属を含まない強化プラスチック等で形成されるが、その本体部２の手前側の壁面を地上子Ａの手前側の端面Ａａよりも手前側に延設して延設部３を設けた。   As described above, according to the ground unit mounting base 1 according to the present embodiment, the main body 2 of the ground unit mounting base 1 originally does not contain metal so as not to adversely affect the transmission / reception characteristics of the antenna of the ground unit A. Although it is formed of plastic or the like, the wall portion on the near side of the main body portion 2 is extended to the near side with respect to the end surface Aa on the near side of the ground element A to provide the extending portion 3.

このように構成すれば、地上子Ａのアンテナの送受信特性に悪影響を及ぼすことなく、軌道Ｌ上を滑走してきた雪や氷の塊を地上子Ａではなく地上子取付台１の延設部３に衝突させることが可能となる。そのため、延設部３により地上子Ａを防護することが可能となり、地上子Ａが雪や氷の塊と衝突して破壊されることを防止することが可能となる。   If comprised in this way, the extension part 3 of the ground element mounting stand 1 not the ground element A but the snow and ice lump which slid on the track | orbit L without adversely affecting the transmission / reception characteristics of the antenna of the ground element A It becomes possible to make it collide. Therefore, it is possible to protect the ground element A by the extending portion 3, and it is possible to prevent the ground element A from colliding with snow and ice blocks and being destroyed.

また、軌道Ｌのスラブ等に固定されたアンカーボルトＢに対する地上子取付台１の本体部２の取付孔４の位置を、従来の地上子取付台１００を固定するための複数のアンカーボルトＢの位置に対応する位置に設け、地上子Ａを取り付けるための取付部６を、もともと従来の地上子取付台１００に取り付けられていた地上子Ａの取付孔Ａｈに対応する位置に設けるように構成すれば、従来の地上子取付台１００を本実施形態に係る地上子取付台１に取り替える際に、もともとのアンカーボルトＢや地上子Ａをそのまま使うことができる。   Further, the position of the mounting hole 4 of the main body portion 2 of the ground unit mounting base 1 with respect to the anchor bolt B fixed to the slab or the like of the track L is set to a plurality of anchor bolts B for fixing the conventional ground base mounting base 100. The mounting portion 6 for mounting the ground element A is provided at a position corresponding to the position, and is provided at a position corresponding to the mounting hole Ah of the ground element A originally attached to the conventional ground element mounting base 100. For example, when the conventional ground unit mounting base 100 is replaced with the ground unit mounting base 1 according to the present embodiment, the original anchor bolt B and ground unit A can be used as they are.

そのため、アンカーボルトＢを軌道Ｌに固定し直したり、本実施形態に係る地上子取付台１に対応する専用の地上子Ａを製造したりする必要がなく、従来の地上子取付台１００を本実施形態に係る地上子取付台１に交換するだけでよいため、従来の地上子取付台１００から本実施形態に係る地上子取付台１への交換を安価に行うことが可能となる。   Therefore, it is not necessary to fix the anchor bolt B to the track L or to manufacture the dedicated ground unit A corresponding to the ground unit mounting base 1 according to the present embodiment, and the conventional ground unit mounting base 100 is used. Since it is only necessary to replace the ground unit mounting base 1 according to the embodiment, replacement from the conventional ground base mounting base 100 to the ground base mounting base 1 according to the present embodiment can be performed at low cost.

なお、本実施形態に係る地上子取付台１の延設部３は、上記のように、特に進行方向Ｐから滑走してきたり飛んできたりする物体に対してそれらを左右方向に弾き跳ばすことで地上子Ａとの衝突を有効に防止するとともに、地上子取付台１自体が物体の運動エネルギを吸収してアンカーボルトＢからはずれることを有効に防止することができるものである。   In addition, the extension part 3 of the ground support base 1 according to the present embodiment, as described above, in particular, by flipping them in the left-right direction with respect to an object that slides or flies from the traveling direction P. While effectively preventing collision with the ground element A, the ground element mounting base 1 itself can effectively prevent the object from absorbing the kinetic energy of the object and coming off from the anchor bolt B.

そのため、地上子取付台１の延設部３で地上子Ａとの衝突を阻止する対象は、上記のような雪や氷の塊には限定されず、進行方向Ｐから滑走してきたり飛んできたりするすべての物体が対象となる。   Therefore, the object of preventing the collision with the ground element A at the extending portion 3 of the ground element mounting base 1 is not limited to the above-mentioned snow and ice blocks, and the object can slide or fly from the traveling direction P. All objects to be targeted.

また、本実施形態では地上子取付台１をアンカーボルトＢを介して軌道Ｌのスラブに設置する場合について説明したが、これに限定されず、地上子取付台１を枕木等に設置することも可能である。また、本実施形態では地上子取付台１の本体部２と延設部３とを一体成形する場合について説明したが、例えば延設部３を本体部２と別体に形成して本体部２に取り付けるように構成してもよい。さらに、延設部３の壁面８の中央部分８１や左右の壁面８２、８３の周縁部を面取りしてもよい。   Moreover, although this embodiment demonstrated the case where the ground child mounting base 1 was installed in the slab of the track | orbit L via the anchor bolt B, it is not limited to this, The ground child mounting base 1 can also be installed in a sleeper etc. Is possible. In the present embodiment, the case where the main body 2 and the extension 3 of the ground mount 1 are integrally formed has been described. For example, the extension 3 is formed separately from the main body 2 to form the main body 2. You may comprise so that it may attach to. Furthermore, you may chamfer the peripheral part of the center part 81 of the wall surface 8 of the extension part 3, and the left and right wall surfaces 82 and 83. FIG.

また、本実施形態では延設部３の壁面８の左右方向の中央部分８１を手前側に突出させて左右に壁面８２、８３を設けるように壁面８を楔状に形成する場合について説明したが、これに限定されず、例えば図７に示すように、延設部３の壁面８の左右方向の一端部を手前側に突出させ、他端部に向かうに従って奥側に遠ざかるように壁面８を傾斜させて形成することも可能である。   Further, in the present embodiment, the case where the wall surface 8 is formed in a wedge shape so that the center portion 81 in the left-right direction of the wall surface 8 of the extending portion 3 protrudes toward the near side and the wall surfaces 82 and 83 are provided on the left and right sides has been described. For example, as shown in FIG. 7, one end portion of the wall surface 8 of the extending portion 3 protrudes toward the front side, and the wall surface 8 is inclined so as to move away from the back side toward the other end portion. It is also possible to form them.

この場合、通常、当該軌道Ｌを進行する列車に対向する方向に進行する列車が当該列車の右側を進行することから、雪や氷の塊等の物体を左側に弾き跳ばすように構成することが好ましく、図７に示すように、右側の端部を突出させ、左側の端部に向かうに従って奥側に遠ざかるように形成することが好ましい。   In this case, normally, since a train traveling in a direction opposite to the train traveling on the track L travels on the right side of the train, it is configured to bounce objects such as snow and ice blocks to the left side. As shown in FIG. 7, it is preferable that the right end is protruded and formed so as to move away from the back as it goes to the left end.

また、本実施形態や図７に示した形態の地上子取付台１において、図８に示すように、延設部３の壁面８の左右方向の両端部を奥側に延出させて側壁部１３、１３を設けるように構成することも可能である。また、図示を省略するが、壁面８の左右方向の一方側の端部のみを奥側に延出させるように構成することも可能である。   Further, in the ground unit mounting base 1 of the present embodiment and the form shown in FIG. 7, as shown in FIG. 8, both end portions in the left-right direction of the wall surface 8 of the extending portion 3 are extended to the back side to form side walls. 13 and 13 may be provided. Moreover, although illustration is abbreviate | omitted, it is also possible to comprise so that only the edge part of the one side of the left-right direction of the wall surface 8 may be extended in the back | inner side.

このように構成すれば、地上子Ａの手前側の端面Ａａだけでなく、左右方向から飛んでくる物体や延設部３に衝突して破壊された雪や氷の塊の破片等が地上子Ａの側方の端面Ａｃに衝突して地上子Ａが損傷することをも防止することが可能となる。なお、図８では、側壁部１３、１３を地上子Ａの側方の端面Ａｃの半ばまでしか設けない場合が示されているが、側壁部１３、１３の進行方向Ｐの長さをさらに長くしたり或いはより短くしたりすることは適宜行われる。   If constituted in this way, not only the end surface Aa on the near side of the ground element A but also an object flying from the left and right direction, a piece of snow or a block of ice that has been destroyed by colliding with the extended portion 3, etc. It is possible to prevent the ground child A from being damaged by colliding with the side end surface Ac of A. 8 shows a case where the side wall portions 13 and 13 are provided only up to the middle of the side end surface Ac of the ground element A, the length of the side wall portions 13 and 13 in the traveling direction P is further increased. It is appropriately performed to shorten or shorten.

一方、本実施形態では、地上子取付台１の延設部３を本体部２の進行方向Ｐの手前側だけに設ける場合を示したが、図９に示すように、本体部２の進行方向Ｐの奥側の壁面を地上子Ａの奥側の端面Ａｄよりもさらに奥側に延設させてもう１つの延設部である第二延設部３＊を設けるように構成することも可能である。その際、図９に示すように、第二延設部３＊を延設部３と同形に形成すれば、地上子取付台１をアンカーボルトＢに取り付ける際に延設部３と第二延設部３＊のいずれが手前側にくるように設置してもよいため、地上子取付台１の取り付け方向の制限がなくなる。 On the other hand, in the present embodiment, the case where the extending portion 3 of the ground unit mounting base 1 is provided only on the front side of the traveling direction P of the main body portion 2 is shown. However, as shown in FIG. It is also possible to provide a second extending portion 3 * which is another extending portion by extending the inner wall surface of P further to the inner side than the end surface Ad of the ground child A. It is. At this time, as shown in FIG. 9, if the second extending portion 3 * is formed in the same shape as the extending portion 3, the extending portion 3 and the second extending portion are attached when the grounding base 1 is attached to the anchor bolt B. Since any of the installation parts 3 * may be installed on the front side, there is no restriction on the mounting direction of the ground unit mounting base 1.

また、本実施形態のように延設部３のみを設けた場合、図３（Ｂ）に示したように、地上子取付台１が軌道Ｌ上でいわば片持ち状に支持されるため、列車の進行等で軌道Ｌが振動した場合の地上子取付台１の共振が起こり易い。しかし、図９に示したように、本体部２の奥側に第二延設部３＊を設けることで、本体部２の手前側と奥側との重量バランスが良好になり、上記のような共振が起こり難くなり、地上子取付台１の経時的な損傷や破壊の頻度を低減できるという利点がある。 Further, when only the extending portion 3 is provided as in the present embodiment, the ground piece mounting base 1 is supported in a cantilever manner on the track L as shown in FIG. When the orbit L vibrates due to the progress of the above, the ground unit mount 1 is likely to resonate. However, as shown in FIG. 9, by providing the second extending portion 3 * on the back side of the main body portion 2, the weight balance between the near side and the back side of the main body portion 2 is improved, and as described above. Resonance is less likely to occur, and there is an advantage that the frequency of damage and destruction over time of the ground support base 1 can be reduced.

さらに、地上子取付台１や地上子Ａが設置された軌道Ｌが単線である場合には進行方向Ｐの奥側から進行してくる列車から雪や氷の塊が落下する等する場合があり、その場合には奥側から雪や氷の塊等の物体が滑走してきたり飛来して地上子取付台１等に衝突する。また、軌道Ｌが複線の場合には、地上子取付台１等が設置された軌道Ｌに他の軌道から物体が飛来する場合がある。そのため、本体部２の奥側に第二延設部３＊を設けることで、このように奥側から物体が飛来等してくる場合にも地上子Ａを防護できるという利点もある。なお、図９のように延設部３のほかに第二延設部３＊を設ける場合にも、図７や図８に示した変形例を適用することが可能である。 Furthermore, when the track L on which the ground unit mounting base 1 and the ground unit A are installed is a single line, a snow or ice lump may fall from a train traveling from the back side in the traveling direction P. In that case, an object such as snow or a lump of ice slides or flies from the rear side and collides with the ground element mounting base 1 or the like. Further, when the track L is a double track, an object may fly from another track to the track L on which the ground unit mount 1 or the like is installed.
