 この排障装置100は、線路を横断するように延びる衝突バー111と、この衝突バー111の両端部に連結された一対の作動部材112(図12では一方の作動部材のみを図示)と、これらの作動部材112を支持する一対の支持部材120を含む。各作動部材112は、衝突バー111の両端部から後方に向かって斜め上方に延びている。また、各作動部材112は、支持部材120と関節ジョイント140によって回転可能に連結されているとともに、固定手段150によって支持部材120に対する回転が拘束されている。固定手段150は、例えばシェアピンである。 The obstacle device 100 includes a collision bar 111 extending so as to cross the track, a pair of operation members 112 (only one operation member is shown in FIG. 12) coupled to both ends of the collision bar 111, these A pair of support members 120 that support the actuating member 112 is included. Each actuating member 112 extends obliquely upward from both ends of the collision bar 111 toward the rear. In addition, each actuating member 112 is rotatably connected to the support member 120 and the joint joint 140, and rotation with respect to the support member 120 is restricted by the fixing means 150. The fixing means 150 is, for example, a shear pin.
 支持部材120には、作動部材112までの距離を計測する距離センサ130が取り付けられている。鉄道車両が脱線すると、衝突バー111とレールとの衝突により固定手段150が破壊され、作動部材112が上方に回転する。一方、線路上に障害物があると、衝突バー111と障害物との衝突により固定手段150が破壊され、作動部材112が後方に回転する。それ故に、距離センサ130によって作動部材112までの距離の増減を検出することにより、脱線及び障害物を検知することができる。 A distance sensor 130 for measuring the distance to the operation member 112 is attached to the support member 120. When the railcar derails, the fixing means 150 is broken by the collision between the collision bar 111 and the rail, and the operating member 112 rotates upward. On the other hand, if there is an obstacle on the track, the fixing means 150 is destroyed by the collision between the collision bar 111 and the obstacle, and the operation member 112 rotates backward. Therefore, derailment and obstacles can be detected by detecting increase / decrease in the distance to the operation member 112 by the distance sensor 130.

 しかしながら、図12に示す排障装置100では、一たび脱線又は障害物の検知が行われると固定手段150が破壊されるため、排障装置100を再使用することができない。 However, in the obstruction device 100 shown in FIG. 12, once the derailment or the detection of an obstacle is performed, the fixing means 150 is destroyed, and therefore the obstruction device 100 cannot be reused.
 そこで、本発明は、少なくとも障害物の検知後に再使用が可能な鉄道車両の排障装置を提供することを目的とする。 Therefore, an object of the present invention is to provide a railway vehicle obstacle device that can be reused at least after an obstacle is detected.
 前記課題を解決するために、本発明の鉄道車両の排障装置は、脱線及び障害物の検知が可能な鉄道車両の排障装置であって、台車の前方で線路を横断するように延びる衝突バーと、前記衝突バーの両端部に連結された一対の作動部材と、前記一対の作動部材を、前記衝突バーよりも後方かつ上方で車幅方向に延びる回転シャフトを介して支持する一対の支持部材と、前記一対の作動部材のそれぞれを正規位置に維持する弾性体であって、当該弾性体の弾性変形により前記作動部材が前記回転シャフト回りに少なくとも後方へ回転することを許容する弾性体と、前記一対の作動部材の少なくとも一方が上方へ所定角度以上回転したときに第1信号を発生するとともに前記作動部材が後方へ所定角度以上回転したときに第2信号を発生する信号発生器と、を備える、ことを特徴とする。 In order to solve the above-mentioned problems, the railroad vehicle fault device of the present invention is a railcar fault device capable of derailment and detection of an obstacle, and the collision extends so as to cross the track in front of the carriage. A pair of supports that support the bar, a pair of actuating members connected to both ends of the collision bar, and the pair of actuating members via a rotating shaft that extends rearward and above the collision bar in the vehicle width direction. An elastic body that maintains each of the member and the pair of actuating members in a normal position, the elastic body allowing the actuating member to rotate at least rearward around the rotating shaft by elastic deformation of the elastic body; A signal that generates a first signal when at least one of the pair of operating members rotates upward by a predetermined angle and generates a second signal when the operating member rotates backward by a predetermined angle or more. It comprises a raw device, and characterized in that.
 上記の構成によれば、鉄道車両が脱線すると、衝突バーとレールとの衝突により作動部材が上方に所定角度以上回転して信号発生器が第1信号を発生する。一方、線路上に衝突バーとの衝撃が所定値以上となる障害物があると、衝突バーと障害物との衝突により作動部材が後方に所定角度以上回転して信号発生器が第2信号を発生する。これにより、脱線及び所定の重さ以上の障害物を検知することができる。しかも、作動部材は弾性体の弾性変形によって少なくとも後方へ回転可能となっているので、作動部材に回転力が付与されて障害物の検知が行われても、作動部材から回転力を取り除けば弾性体が元の状態に戻って作動部材が正規位置に復帰する。従って、障害物の検知後に排障装置を再使用することができる。 According to the above configuration, when the railway vehicle derails, the operation member rotates upward by a predetermined angle or more due to the collision between the collision bar and the rail, and the signal generator generates the first signal. On the other hand, if there is an obstacle on the track where the impact with the collision bar exceeds a predetermined value, the operation member rotates backward by a predetermined angle due to the collision between the collision bar and the obstacle, and the signal generator generates the second signal. appear. Thereby, derailment and the obstacle more than predetermined weight are detectable. In addition, since the operating member can be rotated at least backward by the elastic deformation of the elastic body, even if the rotating force is applied to the operating member and the obstacle is detected, the operating member is elastic if the rotating force is removed from the operating member. The body returns to its original state and the actuating member returns to the normal position. Therefore, the obstacle device can be reused after the obstacle is detected.
 本発明によれば、少なくとも障害物の検知後に再使用が可能な鉄道車両の排障装置が提供される。 According to the present invention, there is provided a railroad vehicle obstacle device that can be reused at least after an obstacle is detected.

 <第1実施形態>
 図1に、第1実施形態に係る鉄道車両の排障装置1Aを示す。この排障装置1Aは、台車11の前方で図略の線路(軌道及びレール対)を横断するように延びる衝突バー10と、この衝突バー10の両端部に連結された一対の作動部材2A,2Bを含む。また、排障装置1Aは、作動部材2A,2Bを回転可能に支持する一対の支持部材3A,3Bと、台車11の前端部から前方に垂れ下がる一対のフレーム4A,4Bを含む。支持部材3A,3Bは、フレーム4A,4Bにそれぞれ取り付けられている。
<First Embodiment>
FIG. 1 shows a railroad vehicle obstacle apparatus 1A according to the first embodiment. This evacuation device 1A includes a collision bar 10 that extends in front of a carriage 11 so as to cross an unillustrated track (a track and a pair of rails), and a pair of actuating members 2A that are coupled to both ends of the collision bar 10. 2B is included. Further, the obstruction device 1A includes a pair of support members 3A and 3B that rotatably support the operation members 2A and 2B, and a pair of frames 4A and 4B that hang forward from the front end of the carriage 11. Support members 3A and 3B are attached to frames 4A and 4B, respectively.
 衝突バー10は、線路上の障害物を線路の両側へ跳ね飛ばすように、中央が前方に突出する略V字状の形状を有している。ただし、衝突バー10は、鉄道車両の車幅方向と平行なストレートであってもよい。また、本実施形態では、衝突バー10の断面形状が円形状であるが、衝突バー10の断面形状は、例えば矩形状などの他の形状であってもよい。 The collision bar 10 has a substantially V-shaped shape whose center protrudes forward so that an obstacle on the track jumps to both sides of the track. However, the collision bar 10 may be a straight parallel to the vehicle width direction of the railway vehicle. Moreover, in this embodiment, although the cross-sectional shape of the collision bar 10 is circular, the cross-sectional shape of the collision bar 10 may be other shapes such as a rectangular shape.
 左側の作動部材2B、支持部材3B及びフレーム4Bは、右側の作動部材2A、支持部材3A及びフレーム4Aと対称であり、右側の作動部材2A、支持部材3A及びフレーム4Aと同様の構造を有する。このため、以下では、図2~図4を参照して、右側の作動部材2A、支持部材3A及びフレーム4Aの構造を代表して説明する。 The left operating member 2B, the supporting member 3B, and the frame 4B are symmetrical to the right operating member 2A, the supporting member 3A, and the frame 4A, and have the same structure as the right operating member 2A, the supporting member 3A, and the frame 4A. Therefore, in the following, the structure of the right side actuating member 2A, the supporting member 3A, and the frame 4A will be described as a representative with reference to FIGS.
 作動部材2Aは、衝突バー10の端部から後方に向かって斜め上方に延びている。具体的に、作動部材2Aは、軸方向が車幅方向と平行な筒状のベース21と、このベース21と衝突バー10の端部との間に介在するアーム23を含む。アーム23は、車幅方向と直交する中央壁24と、互いに対向して中央壁24を挟み込む前壁25及び後壁26を含む。 The actuating member 2A extends obliquely upward from the end of the collision bar 10 toward the rear. Specifically, the actuating member 2 </ b> A includes a cylindrical base 21 whose axial direction is parallel to the vehicle width direction, and an arm 23 interposed between the base 21 and the end of the collision bar 10. The arm 23 includes a central wall 24 that is orthogonal to the vehicle width direction, and a front wall 25 and a rear wall 26 that face each other and sandwich the central wall 24.
 支持部材3Aは、回転シャフト5を介して作動部材2Aのベース21を支持している。回転シャフト5は、衝突バー10よりも後方かつ上方で車幅方向に延びている。支持部材3Aは、鉄道車両の車長方向と直交する、鉛直方向に長い主板31と、主板31の略中央から作動部材2Aのベース21を挟み込むように前方に突出する一対の受け板33を含む。そして、受け板33に、回転シャフト5の両端部が保持されている。 The support member 3 </ b> A supports the base 21 of the operation member 2 </ b> A via the rotary shaft 5. The rotating shaft 5 extends in the vehicle width direction behind and above the collision bar 10. The support member 3A includes a main plate 31 that is perpendicular to the vehicle length direction of the railway vehicle and that is long in the vertical direction, and a pair of receiving plates 33 that protrude forward from approximately the center of the main plate 31 so as to sandwich the base 21 of the operation member 2A. . And the both ends of the rotating shaft 5 are hold | maintained at the receiving plate 33. FIG.
 各受け板33には、上向きに開口する溝34が設けられている。回転シャフト5の端部は、溝34に嵌め込まれた状態でボルトB1により受け板33に固定されている。ただし、受け板33への回転シャフト5の固定方法はこれに限らず種々の方法が採用可能である。 Each receiving plate 33 is provided with a groove 34 that opens upward. The end of the rotating shaft 5 is fixed to the receiving plate 33 by a bolt B1 while being fitted in the groove 34. However, the method of fixing the rotating shaft 5 to the receiving plate 33 is not limited to this, and various methods can be employed.
 作動部材2Aのベース21には、回転シャフト5を中心とする保持穴22が設けられている。保持穴22には、回転シャフト5に挿通されたゴムブッシュ61が挿入されている。本実施形態では、ゴムブッシュ61が保持穴22に圧入され、これによりゴムブッシュ61がベース21に対して回転不能となっている。また、ゴムブッシュ61は、回転シャフト5に接合されている。このため、ゴムブッシュ61は、作動部材2Aを図4に示す正規位置(衝突バー10が図略の線路に近接する位置)に維持する弾性体として機能する。 The base 21 of the actuating member 2A is provided with a holding hole 22 with the rotary shaft 5 as the center. A rubber bush 61 inserted through the rotary shaft 5 is inserted into the holding hole 22. In this embodiment, the rubber bush 61 is press-fitted into the holding hole 22 so that the rubber bush 61 cannot rotate with respect to the base 21. The rubber bush 61 is joined to the rotary shaft 5. Therefore, the rubber bush 61 functions as an elastic body that maintains the actuating member 2A at the normal position shown in FIG. 4 (position where the collision bar 10 is close to the line not shown).
 また、ゴムブッシュ61は、比較的に厚い肉厚を有している。このため、作動部材2Aは、ゴムブッシュ61の弾性変形によって、図4中に矢印Aで示すように回転シャフト5回りに上方に回転できるとともに、図4中に矢印Bで示すように回転シャフト5回りに後方に回転可能である。すなわち、ゴムブッシュ61は、作動部材2Aの上方及び後方への回転を許容している。 Further, the rubber bush 61 has a relatively thick wall thickness. Therefore, the actuating member 2A can rotate upward around the rotating shaft 5 as indicated by an arrow A in FIG. 4 due to elastic deformation of the rubber bush 61, and the rotating shaft 5 as indicated by an arrow B in FIG. Can rotate backwards around. That is, the rubber bush 61 allows the operation member 2A to rotate upward and backward.
 さらに、本実施形態では、ゴムブッシュ61が後ろ向きに過剰に捩じられることを防止するために、支持部材3Aの主板31に、作動部材2Aが後方に回転したときに作動部材2Aのアーム23の後壁26に当接するストッパー35が設けられている。ストッパー35は、受け板33の間に配置されている。ただし、ストッパー35は、アーム23の後壁26に設けられていてもよい。 Further, in the present embodiment, in order to prevent the rubber bush 61 from being excessively twisted backward, the main plate 31 of the support member 3A has the arm 23 of the operation member 2A when the operation member 2A rotates rearward. A stopper 35 that contacts the rear wall 26 is provided. The stopper 35 is disposed between the receiving plates 33. However, the stopper 35 may be provided on the rear wall 26 of the arm 23.
 支持部材3Aは、ボルトB2によってフレーム4Aに固定されている。支持部材3Aは、フレーム4Aに対する高さ調整が可能に構成されている。具体的には、支持部材3Aの主板31の裏面には、歯付突起36を有する第1係合板37が接合(例えば、溶接)されている。一方、フレーム4Aの前面には、座板41が接合(例えば、溶接)されており、この座板41に、歯付突起36と噛み合う歯付凹部を有する第2係合板42が接合(例えば、溶接)されている。主板31及び第1係合板37には、上下方向に延びる複数(図例では4つ)の長穴32が設けられており、これらの長穴32にボルトB2が挿通されている。 The support member 3A is fixed to the frame 4A by bolts B2. The support member 3A is configured to be height adjustable with respect to the frame 4A. Specifically, a first engagement plate 37 having a toothed projection 36 is joined (for example, welded) to the back surface of the main plate 31 of the support member 3A. On the other hand, a seat plate 41 is joined (for example, welded) to the front surface of the frame 4A, and a second engagement plate 42 having a toothed recess that meshes with the toothed projection 36 is joined to the seat plate 41 (for example, for example, Welding). The main plate 31 and the first engagement plate 37 are provided with a plurality of (four in the illustrated example) elongated holes 32 extending in the vertical direction, and bolts B <b> 2 are inserted through these elongated holes 32.
 支持部材3Aの主板31の下部には、ブラケット30を介して信号発生器7が取り付けられている。本実施形態では、双方の支持部材3A,3Bに信号発生器7が取り付けられているが、信号発生器7は支持部材3A,3Bの少なくとも一方に取り付けられていればよい。 The signal generator 7 is attached to the lower part of the main plate 31 of the support member 3A via a bracket 30. In the present embodiment, the signal generator 7 is attached to both the support members 3A and 3B, but the signal generator 7 may be attached to at least one of the support members 3A and 3B.
 信号発生器7は、作動部材2Aが上方へ所定角度(例えば、2~10度)以上回転したときに第1信号(脱線検知信号)を発生し、作動部材2Aが後方へ所定角度(例えば、2~10度)以上回転したときに第2信号(障害物検知信号)を発生する。第1信号及び第2信号は、オン信号(a接点)であってもよいしオフ信号(b接点)であってもよい。信号発生器7が発生する第1信号及び第2信号は、ケーブル74を通じて鉄道車両の車体に搭載された制御装置に送られ、これにより非常ブレーキがかけられる。 The signal generator 7 generates a first signal (derailment detection signal) when the operating member 2A rotates upward by a predetermined angle (for example, 2 to 10 degrees), and the operating member 2A moves backward by a predetermined angle (for example, A second signal (obstacle detection signal) is generated when the motor rotates more than 2 to 10 degrees. The first signal and the second signal may be an on signal (a contact) or an off signal (b contact). The first signal and the second signal generated by the signal generator 7 are sent to the control device mounted on the vehicle body of the railway vehicle through the cable 74, whereby an emergency brake is applied.
 本実施形態では、信号発生器7として、リミットスイッチ70が用いられている。リミットスイッチ70は、作動部材2Aのアーム23に対して車幅方向の外側に配置されている。ただし、リミットスイッチ70は、アーム23に対して車幅方向の内側に配置されていてもよい。 In this embodiment, a limit switch 70 is used as the signal generator 7. The limit switch 70 is disposed on the outer side in the vehicle width direction with respect to the arm 23 of the operating member 2A. However, the limit switch 70 may be disposed inside the vehicle width direction with respect to the arm 23.
 リミットスイッチ70は、ブラケット30に固定された本体部73と、本体部73から車幅方向の内側に突出するヘッド72と、ヘッド72から斜め下方に延び、作動部材2Aの後方及び上方への回転に伴って傾倒する棒状の検知レバー71を有している。ただし、リミットスイッチ70は、棒状の検知レバー71の代わりに、ローラが取り付けられた検知アームを有していてもよい。 The limit switch 70 includes a main body 73 fixed to the bracket 30, a head 72 projecting inward in the vehicle width direction from the main body 73, and extends obliquely downward from the head 72, and rotates the operation member 2A rearward and upward. It has a rod-shaped detection lever 71 that tilts along with it. However, the limit switch 70 may have a detection arm to which a roller is attached instead of the rod-shaped detection lever 71.
 作動部材2Aのアーム23の中央壁24には、検知レバー71を挟むように当該中央壁24から車幅方向の外側に突出する一対の作動片27が設けられている。本実施形態では、各作動片27が円柱状をなしている。 The central wall 24 of the arm 23 of the actuating member 2A is provided with a pair of actuating pieces 27 projecting outward from the central wall 24 in the vehicle width direction so as to sandwich the detection lever 71 therebetween. In the present embodiment, each operating piece 27 has a cylindrical shape.
 各作動片27と検知レバー71との間には、一定の隙間が形成されている。このため、走行時の振動による検知レバー71への作動片27の接触を回避することができる。また、本実施形態では検知レバー71の揺動中心(ヘッド72の回転中心)は回転シャフト5の中心よりも下方に位置しているために、各作動片27と検知レバー71との間に隙間が形成されていないと、作動部材2Aの回転時に検知レバー71が作動片27によって曲げられることがある。これに対し、各作動片27と検知レバー71との間に一定の隙間が形成されていれば、検知レバー71の曲げ変形を防止できる。 A certain gap is formed between each operating piece 27 and the detection lever 71. For this reason, the contact of the operating piece 27 to the detection lever 71 due to vibration during traveling can be avoided. Further, in this embodiment, the swing center of the detection lever 71 (rotation center of the head 72) is located below the center of the rotary shaft 5, so that there is a gap between each operating piece 27 and the detection lever 71. Is not formed, the detection lever 71 may be bent by the operating piece 27 when the operating member 2A rotates. On the other hand, if a certain gap is formed between each operating piece 27 and the detection lever 71, the bending deformation of the detection lever 71 can be prevented.
 次に、図4を参照して排障装置1Aの動作を説明する。鉄道車両が脱線すると、衝突バー10が図略のレールと衝突する。これにより、作動部材2Aが図4中に矢印Aで示すように上方に所定角度以上回転し、リミットスイッチ70の検知レバー71が後側の作動片27によって前方に傾倒され、リミットスイッチ70が第1信号を発生する。その結果、脱線を検知することができる。 Next, the operation of the obstruction device 1A will be described with reference to FIG. When the railcar derails, the collision bar 10 collides with a rail (not shown). As a result, the actuating member 2A rotates upward by a predetermined angle or more as shown by an arrow A in FIG. 4, the detection lever 71 of the limit switch 70 is tilted forward by the actuating piece 27 on the rear side, and the limit switch 70 is 1 signal is generated. As a result, derailment can be detected.
 一方、線路上に障害物があると、衝突バー10が図略の障害物と衝突する。これにより、作動部材2Aが図4中に矢印Bで示すように後方に回転する。衝突バー10との衝撃が所定値以上となる障害物であれば、作動部材2Aが後方へ所定角度以上回転し、リミットスイッチ70の検知レバー71が前側の作動片27によって後方に傾倒され、リミットスイッチ70が第2信号を発生する。その結果、所定の重さ以上の障害物を検知することができる。ただし、作動部材2Aを所定角度以上に回転させない程度に障害物が軽い場合には、その障害物は衝突バー10によって跳ね飛ばされる。 On the other hand, if there is an obstacle on the track, the collision bar 10 collides with an obstacle not shown. As a result, the operating member 2A rotates backward as indicated by an arrow B in FIG. If the obstacle with an impact with the collision bar 10 exceeds a predetermined value, the actuating member 2A rotates rearward by a predetermined angle or more, the detection lever 71 of the limit switch 70 is tilted rearward by the front actuating piece 27, and the limit Switch 70 generates a second signal. As a result, an obstacle having a predetermined weight or more can be detected. However, when the obstacle is light enough not to rotate the actuating member 2 </ b> A beyond a predetermined angle, the obstacle is bounced off by the collision bar 10.
 そして、本実施形態では、作動部材2Aがゴムブッシュ61の弾性変形によって上方及び後方へ回転可能となっているので、作動部材2Aに回転力が付与されて脱線及び障害物のいずれの検知が行われても、作動部材2Aから回転力を取り除けばゴムブッシュ61が元の状態に戻って作動部材2Aが正規位置に復帰する。従って、脱線及び障害物のいずれの検知後にも排障装置1Aを再使用することができる。 In this embodiment, since the operating member 2A can be rotated upward and backward by elastic deformation of the rubber bush 61, a rotational force is applied to the operating member 2A to detect either derailment or an obstacle. Even if the rotating force is removed from the operating member 2A, the rubber bush 61 returns to the original state and the operating member 2A returns to the normal position. Therefore, the obstruction device 1A can be reused after detecting any derailment or obstacle.
 また、本実施形態では、リミットスイッチ70の検知レバー71の揺動中心が回転シャフト5の中心から約100mm下方に位置している。このため、作動部材2Aの回転量に対して検知レバー71の傾倒量を拡大できる。従って、リミットスイッチ70が第1信号及び第2信号を発生するタイミングを、作動部材2Aが比較的に小さい角度だけ回転したときとすることができ、ゴムブッシュ61を保護することができる。 In this embodiment, the swing center of the detection lever 71 of the limit switch 70 is located about 100 mm below the center of the rotary shaft 5. For this reason, the inclination amount of the detection lever 71 can be enlarged with respect to the rotation amount of the operation member 2A. Therefore, the timing at which the limit switch 70 generates the first signal and the second signal can be set when the operation member 2A is rotated by a relatively small angle, and the rubber bush 61 can be protected.
 (変形例)
 上述した第1実施形態は、次のように変更することも可能である。
(Modification)
The first embodiment described above can be modified as follows.
 排障装置1Aは必ずしも一対のフレーム4A,4Bを含む必要はなく、台車11の形状によっては、支持部材3A,3Bが台車11の前端部に直接取り付けられていてもよい。 The obstruction device 1 </ b> A does not necessarily include the pair of frames 4 </ b> A and 4 </ b> B, and the support members 3 </ b> A and 3 </ b> B may be directly attached to the front end portion of the carriage 11 depending on the shape of the carriage 11.
 また、作動部材2A,2Bのそれぞれを正規位置に維持する弾性体は、必ずしもゴムブッシュ61である必要はなく、例えば図5に示すように、圧縮コイルばね62であってもよい。あるいは、弾性体として、板ばねや捩じりばねなどを用いることも可能である。ただし、前記実施形態のように弾性体としてゴムブッシュ61を用いれば、弾性体回りの構造をシンプルにすることができる。さらに、弾性体として金属製のばねを用いた場合には弾性体が台車11の振動に共振する可能性があるのに対し、弾性体としてゴムブッシュ61を用いた場合にはゴムブッシュ61の減衰性能によりゴムブッシュ61の共振はほとんど生じない。 Further, the elastic body that maintains each of the operating members 2A and 2B in the normal position is not necessarily the rubber bush 61, and may be a compression coil spring 62 as shown in FIG. Alternatively, a plate spring or a torsion spring can be used as the elastic body. However, if the rubber bush 61 is used as the elastic body as in the above embodiment, the structure around the elastic body can be simplified. Further, when a metal spring is used as the elastic body, the elastic body may resonate with the vibration of the carriage 11, whereas when the rubber bush 61 is used as the elastic body, the damping of the rubber bush 61 is performed. The performance of the rubber bush 61 hardly occurs depending on the performance.
 また、信号発生器7は、必ずしもリミットスイッチ70である必要はなく、例えば図5に示すような距離センサ75であってもよいし、タッチセンサであってもよい。あるいは、信号発生器7としては、回転角検出センサなどを用いることも可能である。ただし、前記実施形態のようにリミットスイッチ70を用いれば、検知レバー71に対する物理的な接触によって作動部材(2A及び/又は2B)の回転を確実に検出することができる。 Further, the signal generator 7 is not necessarily the limit switch 70, and may be a distance sensor 75 as shown in FIG. 5 or a touch sensor, for example. Alternatively, as the signal generator 7, a rotation angle detection sensor or the like can be used. However, if the limit switch 70 is used as in the above embodiment, the rotation of the actuating member (2A and / or 2B) can be reliably detected by physical contact with the detection lever 71.
 リミットスイッチ70を用いる場合は、検知レバー71の向きは、例えば水平方向(鉄道車両の車長方向又は車幅方向)であってもよい。この検知レバー71の向きに合わせて、一対の作動片27の突出方向も適宜変更可能である。 When the limit switch 70 is used, the direction of the detection lever 71 may be, for example, the horizontal direction (the vehicle length direction or the vehicle width direction of the railway vehicle). According to the direction of the detection lever 71, the protruding direction of the pair of operating pieces 27 can be changed as appropriate.

It has the structure of. Therefore, in the following, the structure of the right actuating member 2A, the supporting member 3A, and the frame 4A will be described as a representative with reference to FIGS.
 本実施形態では、支持部材3Aの主板31がフレーム4Aに接合(例えば、溶接)されている。ただし、第1実施形態と同様に、支持部材3AがボルトB2によってフレーム4Aに固定されてもよい。また、本実施形態では、回転シャフト5の各端部が、ボルトB1及びナットN1により受け板33に固定されている。 In the present embodiment, the main plate 31 of the support member 3A is joined (for example, welded) to the frame 4A. However, similarly to the first embodiment, the support member 3A may be fixed to the frame 4A by the bolt B2. Moreover, in this embodiment, each edge part of the rotating shaft 5 is being fixed to the receiving plate 33 with the volt | bolt B1 and the nut N1.
 さらに、本実施形態では、衝突バー10の端部に高さ調整用の構造体12が設けられており、この構造体12を介して作動部材2Aが衝突バー10の端部に連結されている。そして、作動部材2Aのアーム23が、ベース21から鉛直下向きに延びている。 Further, in the present embodiment, a height adjusting structure 12 is provided at the end of the collision bar 10, and the actuating member 2 </ b> A is connected to the end of the collision bar 10 via the structure 12. . The arm 23 of the operating member 2 </ b> A extends vertically downward from the base 21.
 具体的に、アーム23は、ベース21の前端に対応する位置に配置された、鉄道車両の車長方向に垂直な前壁28と、前壁28及びベース21に接合(例えば、溶接)された左右一対の側壁29を含む。 Specifically, the arm 23 is disposed at a position corresponding to the front end of the base 21 and is joined (for example, welded) to the front wall 28 perpendicular to the vehicle length direction of the railway vehicle and the front wall 28 and the base 21. A pair of left and right side walls 29 is included.
 本実施形態では、フレーム4Aにおける支持部材3Aの下方の部分に、作動部材2Aが後方に回転したときに作動部材2Aのアーム23の側壁29に当接するストッパー16が設けられている。ただし、支持部材3Aの主板31が下向きに長くされ、その主板31の下部にストッパー16が設けられてもよい。また、ストッパー16は、衝撃吸収用部材として用いられてもよく、この場合には交換を可能とするためにフレーム4Aから取り外しできる構造であってもよい。 In the present embodiment, a stopper 16 that contacts the side wall 29 of the arm 23 of the actuating member 2A when the actuating member 2A rotates backward is provided in a portion below the support member 3A in the frame 4A. However, the main plate 31 of the support member 3 </ b> A may be elongated downward and the stopper 16 may be provided below the main plate 31. The stopper 16 may be used as an impact absorbing member. In this case, the stopper 16 may have a structure that can be removed from the frame 4A in order to allow replacement.
 構造体12は、衝突バー10のフレーム4Aに対する高さを調整するためのものである。具体的に、構造体12は、衝突バー10の端部の後方に位置する、鉄道車両の車長方向に垂直な係合板14と、係合板14及び衝突バー10に接合(例えば、溶接)された左右一対のリブ13を含む。係合板14は、後面に歯付突起15を有している。一方、アーム23の前壁28は、前面に歯付突起15と噛み合う歯付凹部を有している。 The structure 12 is for adjusting the height of the collision bar 10 with respect to the frame 4A. Specifically, the structure 12 is joined (for example, welded) to the engagement plate 14 positioned behind the end of the collision bar 10 and perpendicular to the vehicle length direction of the railway vehicle, and the engagement plate 14 and the collision bar 10. A pair of left and right ribs 13 is included. The engagement plate 14 has a toothed projection 15 on the rear surface. On the other hand, the front wall 28 of the arm 23 has a toothed recess that meshes with the toothed protrusion 15 on the front surface.
 アーム23の前壁28には、上下方向に延びる長穴が設けられており、その長穴に挿通される2つのボルトB3によって係合板14が前壁28に固定されている。 A long hole extending in the vertical direction is provided in the front wall 28 of the arm 23, and the engagement plate 14 is fixed to the front wall 28 by two bolts B3 inserted through the long hole.
 本実施形態でも、ゴムブッシュ61が、作動部材2Aを図8に示す正規位置(衝突バー10が図略の線路に近接する位置)に維持する弾性体として機能する。さらに、本実施形態では、作動部材2Aを正規位置に維持する弾性体として、板ばね63も採用されている。 Also in this embodiment, the rubber bush 61 functions as an elastic body that maintains the actuating member 2A in the normal position shown in FIG. 8 (position where the collision bar 10 is close to the line not shown). Furthermore, in this embodiment, the leaf | plate spring 63 is also employ | adopted as an elastic body which maintains 2 A of operation members in a regular position.
 板ばね63は、作動部材2Aを後方から係止部材17に押し付けることによって正規位置に維持する。すなわち、板ばね63は、当該板ばね63の弾性変形により作動部材2Aの後方への回転を許容している。 The leaf spring 63 maintains the normal position by pressing the operating member 2A against the locking member 17 from the rear. That is, the leaf spring 63 allows the actuation member 2 </ b> A to rotate backward due to elastic deformation of the leaf spring 63.
 本実施形態では、係止部材17が、作動部材2Aの前方から作動部材2Aのアーム23の両脇を通って後方に延び、両端が支持部材3Aの主板31にナットN2,N3によって固定されたUボルトである。ただし、係止部材17は、必ずしもUボルトである必要はなく、例えばL字状のフックであってもよい。係止部材17は、脱線時に作動部材2Aの上方への回転力によって破壊(破断)し得るように構成されている。 In the present embodiment, the locking member 17 extends rearward from the front of the operating member 2A through both sides of the arm 23 of the operating member 2A, and both ends are fixed to the main plate 31 of the support member 3A by nuts N2 and N3. U bolt. However, the locking member 17 is not necessarily a U-bolt, and may be, for example, an L-shaped hook. The locking member 17 is configured so that it can be broken (broken) by the upward rotational force of the actuating member 2A during derailment.
 板ばね63は、作動部材2Aを上方から覆うように前後方向(車長方向)の中央で大きく湾曲している。図8では、板ばね63が変形させられた付勢状態となっているために板ばね63がU字状になっているが、板ばね63は自然状態では図11に示すような形状である。板ばね63の後側部分の下端は、ボルトB7によって支持部材3Aの主板31に固定されている。 The leaf spring 63 is greatly curved at the center in the front-rear direction (vehicle length direction) so as to cover the operating member 2A from above. In FIG. 8, the leaf spring 63 is U-shaped because the leaf spring 63 is deformed, but the leaf spring 63 has a shape as shown in FIG. 11 in a natural state. . The lower end of the rear portion of the leaf spring 63 is fixed to the main plate 31 of the support member 3A by a bolt B7.
 板ばね63の前側部分の下端は、作動部材2Aに取り付けられた受け部材8に係合している。受け部材8は、作動部材2Aのアーム23に接合(例えば、溶接)されたブロック84と、作動部材2Aのアーム23の前方に位置する係合バー81を含む。ブロック84は、アーム23の前壁28の裏面に沿って側壁29を貫通している。ブロック84の両端面には、前後方向に延びる左右一対の保持片82,83がボルトB5により固定されており、これらの保持片82,83の前端に係合バー81が保持されている。 The lower end of the front portion of the leaf spring 63 is engaged with the receiving member 8 attached to the operating member 2A. The receiving member 8 includes a block 84 joined (for example, welded) to the arm 23 of the operating member 2A, and an engagement bar 81 positioned in front of the arm 23 of the operating member 2A. The block 84 passes through the side wall 29 along the back surface of the front wall 28 of the arm 23. A pair of left and right holding pieces 82 and 83 extending in the front-rear direction are fixed to both end faces of the block 84 by bolts B5, and an engagement bar 81 is held at the front ends of these holding pieces 82 and 83.
 板ばね63の前側部分の下端は、係合バー81に後方から係合することによって、係合バー81と支持部材3Aの主板31とを互いに離間するように付勢している。これにより、作動部材2Aが後方から係止部材17に押し付けられている。 The lower end of the front portion of the leaf spring 63 urges the engagement bar 81 and the main plate 31 of the support member 3A to be separated from each other by engaging with the engagement bar 81 from the rear. Thereby, the operating member 2A is pressed against the locking member 17 from the rear.
 作動部材2Aのアーム23の前壁28の前面には、係止部材17よりも下側位置から上側の厚さが薄くなるように段差が形成されている。そして、この段差の下部に、係止部材17との当接用シート18がボルトB4によって固定されている。当接用シート18は、例えば、樹脂やゴムからなる。 A step is formed on the front surface of the front wall 28 of the arm 23 of the actuating member 2A so that the thickness on the upper side from the position below the locking member 17 becomes thinner. And the sheet | seat 18 for contact | abutting with the latching member 17 is being fixed to the lower part of this level | step difference with the volt | bolt B4. The contact sheet 18 is made of, for example, resin or rubber.
 受け部材8の左右一対の保持片82,83のうち車幅方向の外側に位置する外側保持片82は、内側保持片83よりも後方に延びている。そして、外側保持片82の後端に、ボルトB5によって案内板91が固定されている。案内板91は、車幅方向の外側に湾曲しながら支持部材3Aの脇を通ってフレーム4Aの側方まで後方に延びている。 Out of the pair of left and right holding pieces 82, 83 of the receiving member 8, the outer holding piece 82 positioned outside in the vehicle width direction extends rearward from the inner holding piece 83. A guide plate 91 is fixed to the rear end of the outer holding piece 82 by a bolt B5. The guide plate 91 extends rearward to the side of the frame 4A through the side of the support member 3A while being curved outward in the vehicle width direction.
 フレーム4Aの案内板91と対応する位置には、ブラケット40を介して信号発生器7が取り付けられている。本実施形態では、双方のフレーム4A,4Bに信号発生器7が取り付けられているが、信号発生器7はフレーム4A,4Bの少なくとも一方に取り付けられていればよい。 The signal generator 7 is attached via a bracket 40 at a position corresponding to the guide plate 91 of the frame 4A. In the present embodiment, the signal generator 7 is attached to both the frames 4A and 4B, but the signal generator 7 may be attached to at least one of the frames 4A and 4B.
 本実施形態では、リミットスイッチ70のヘッド72が、ブラケット40に固定された本体部73から車幅方向の外側へ突出し、棒状の検知レバー71がヘッド72から前方へ延びている。ただし、リミットスイッチ70は、棒状の検知レバー71の代わりに、ローラが取り付けられた検知アームを有していてもよい。 In this embodiment, the head 72 of the limit switch 70 protrudes outward in the vehicle width direction from the main body 73 fixed to the bracket 40, and the rod-shaped detection lever 71 extends forward from the head 72. However, the limit switch 70 may have a detection arm to which a roller is attached instead of the rod-shaped detection lever 71.
 案内板91の後端には、検知レバー71を挟むように案内板91から車幅方向の内側に突出する一対の作動片92が取り付けられている。つまり、作動片92は、案内板91および外側保持片82を介して作動部材2Aに設けられている。なお、案内板91の後部及びリミットスイッチ70は、車幅方向の外側からカバー77で覆われており、このカバー77は、ボルトB8によってフレーム4Aに固定されている。 At the rear end of the guide plate 91, a pair of operating pieces 92 that protrudes inward in the vehicle width direction from the guide plate 91 so as to sandwich the detection lever 71 are attached. That is, the operating piece 92 is provided on the operating member 2 </ b> A via the guide plate 91 and the outer holding piece 82. The rear portion of the guide plate 91 and the limit switch 70 are covered with a cover 77 from the outside in the vehicle width direction, and the cover 77 is fixed to the frame 4A with bolts B8.
 次に、図10及び図11を参照して排障装置1Aの動作を説明する。鉄道車両が脱線すると、衝突バー10が図略のレールと衝突する。これにより、図11に示すように、作動部材2Aの上方への回転力によって係止部材17が破壊(破断)されて、作動部材2Aが上方に回転する。作動部材2Aが上方へ所定角度以上回転すると、リミットスイッチ70の検知レバー71が上側の作動片92によって下方に傾倒され、リミットスイッチ70が第1信号を発生する。その結果、脱線を検知することができる。 Next, the operation of the obstruction device 1A will be described with reference to FIGS. When the railcar derails, the collision bar 10 collides with a rail (not shown). Thus, as shown in FIG. 11, the locking member 17 is broken (broken) by the upward rotational force of the operating member 2A, and the operating member 2A rotates upward. When the actuating member 2A rotates upward by a predetermined angle or more, the detection lever 71 of the limit switch 70 is tilted downward by the upper actuating piece 92, and the limit switch 70 generates the first signal. As a result, derailment can be detected.
 一方、線路上に障害物があると、衝突バー10が図略の障害物と衝突する。これにより、図10に示すように、作動部材2Aが後方に回転する。衝突バー10との衝撃が所定値以上となる障害物であれば、作動部材2Aが後方へ所定角度以上回転し、リミットスイッチ70の検知レバー71が下側の作動片92によって上方に傾倒され、リミットスイッチ70が第2信号を発生する。その結果、所定の重さ以上の障害物を検知することができる。ただし、作動部材2Aを所定角度以上に回転させない程度に障害物が軽い場合には、その障害物は衝突バー10によって跳ね飛ばされる。 On the other hand, if there is an obstacle on the track, the collision bar 10 collides with an obstacle not shown. Thereby, as shown in FIG. 10, the operation member 2A rotates backward. If the obstacle with the impact with the collision bar 10 is a predetermined value or more, the operating member 2A rotates backward by a predetermined angle or more, the detection lever 71 of the limit switch 70 is tilted upward by the lower operating piece 92, The limit switch 70 generates a second signal. As a result, an obstacle having a predetermined weight or more can be detected. However, when the obstacle is light enough not to rotate the actuating member 2 </ b> A beyond a predetermined angle, the obstacle is bounced off by the collision bar 10.
 そして、本実施形態では、作動部材2Aがゴムブッシュ61及び板ばね63の弾性変形によって後方へ回転可能となっているので、作動部材2Aに回転力が付与されて障害物の検知が行われても、作動部材2Aから回転力を取り除けばゴムブッシュ61及び板ばね63が元の状態に戻って作動部材2Aが正規位置に復帰する。従って、障害物の検知後に排障装置1Aを再使用することができる。 In this embodiment, since the operating member 2A can be rotated rearward by elastic deformation of the rubber bush 61 and the leaf spring 63, a rotational force is applied to the operating member 2A to detect an obstacle. However, if the rotational force is removed from the actuating member 2A, the rubber bush 61 and the leaf spring 63 return to the original state, and the actuating member 2A returns to the normal position. Therefore, the obstacle device 1A can be reused after the obstacle is detected.
 (変形例)
 上述した第2実施形態は、次のように変更することも可能である。
(Modification)
The second embodiment described above can be modified as follows.
 作動部材2A,2Bを正規位置に維持する弾性体としては、ゴムブッシュ61を用いずに板ばね63のみを用いてもよい。この場合、図5に示すのと同様に、回転シャフト5を作動部材2A,2Bのベース21の中心穴に嵌合させればよい。あるいは、板ばね63を用いずに、ゴムブッシュ61のみを用いてもよい。 As the elastic body that maintains the operating members 2A and 2B in the normal positions, only the leaf spring 63 may be used without using the rubber bush 61. In this case, the rotating shaft 5 may be fitted into the center hole of the base 21 of the operating members 2A and 2B, as shown in FIG. Alternatively, only the rubber bush 61 may be used without using the leaf spring 63.
 また、第1実施形態の変形例で説明したうちのいくつか(フレーム4A,4Bがなくてもよいこと、信号発生器7としてリミットスイッチ70以外のセンサが採用可能であること等)が第2実施形態にも適用可能であることは言うまでもない。 Some of the modifications described in the modification of the first embodiment (the frames 4A and 4B are not necessary, a sensor other than the limit switch 70 can be used as the signal generator 7, etc.) are the second. Needless to say, the present invention can also be applied to the embodiment.
