Description

本発明は、ホッパー車に関する。 The present invention relates to a hopper vehicle.

従来、鉄道の軌道を走行して砕石（バラスト）を運搬するホッパー車は、ホッパーから砕石を排出して軌道周辺に散布するように構成している。
例えば、ホッパーの排出口の下方位置にベルトコンベアを設けて、軌道側外方に砕石を散布するものがある（特許文献１参照）。
しかし、ホッパーの下方位置にベルトコンベアを設けると、ホッパーが高位置となり、ホッパー車全体の重心が高くなって、ホッパー上部で作業者が作業する際に安全を確保することが困難という問題や、ベルトコンベア用の大きな駆動源が必要になるといった問題があった。
そこで、図17に示すように、ホッパー40の排出口40ａから砕石を側外方へ滑落させるための誘導勾配面41を設け、砕石を自重により軌道Ｒの左右側外方に滑落させて散布するようにしたホッパー車を使用していた。 Conventionally, a hopper vehicle that travels on a railway track and transports crushed stone (ballast) is configured to discharge the crushed stone from the hopper and spray it around the track.
For example, there is a belt conveyor provided at a position below a discharge port of a hopper to disperse crushed stones outward on the track side (see Patent Document 1).
However, if a belt conveyor is provided below the hopper, the hopper becomes a high position, the center of gravity of the entire hopper vehicle becomes high, and it is difficult to ensure safety when an operator works on the hopper upper part, There was a problem that a large drive source for the belt conveyor was required.
Therefore, as shown in FIG. 17, a guide gradient surface 41 is provided for sliding the crushed stones outwardly from the discharge port 40a of the hopper 40, and the crushed stones are slid down and scattered to the left and right lateral sides of the track R by their own weight. I was using a hopper car.

しかし、図17に示すような誘導勾配面41では、レールｒから一定距離離れた所定位置に砕石が集中するといった問題があった。
そこで、図16に示す比較例のように、ホッパー２´の排出口２ａ´の下方位置に設けた誘導勾配面７´の上下中間部７ｄ´から下端縁７ｂ´までを形成する誘導板部材79´を、上下揺動自在に枢設して、傾斜角度θを変化させて、レールｒの脇やレールｒから遠い位置といった所望の位置に砕石を散布可能とすることが検討された。
しかし、遠くに散布するために誘導板部材79´を長く設けると、二点鎖線で示すように下方へ揺動させた際に、誘導勾配面７´の下端縁７ｂ´（誘導板部材79´の下端縁）が、鉄道走行規則や工事規制等によって規制されている所定の車両下限限界位置Ｙを越えて、車体下方へ突出するといった新たな問題が発生した。 However, in the guiding gradient surface 41 as shown in FIG. 17, there is a problem that crushed stones concentrate at a predetermined position away from the rail r by a certain distance.
Therefore, as in the comparative example shown in FIG. 16, a guide plate member 79 is formed from the upper and lower intermediate portions 7d 'to the lower end edge 7b' of the guide gradient surface 7 'provided at a position below the discharge port 2a' of the hopper 2 '. It has been studied that ′ can be pivoted up and down and the inclination angle θ is changed so that crushed stone can be sprayed to a desired position such as the side of the rail r or a position far from the rail r.
However, if the guide plate member 79 'is provided long to disperse far away, the lower end edge 7b' (guide plate member 79 'of the guide gradient surface 7' when swung downward as shown by a two-dot chain line. A new problem has arisen in that the lower end edge of the vehicle protrudes downward from the vehicle body beyond a predetermined vehicle lower limit position Y that is regulated by railway travel rules and construction regulations.

そこで、本発明は、鉄道走行規則や工事規制等によって規制されている所定の車両下限限界位置を越えることなく、レールから遠い位置やレール脇に砕石を散布可能ホッパー車の提供を目的とする。 Accordingly, an object of the present invention is to provide a hopper vehicle that can disperse crushed stones at a position far from the rail or on the side of the rail without exceeding a predetermined vehicle lower limit limit position regulated by a railroad traveling rule or a construction regulation.

図３乃至図５に於て、第１フラップ部材91及び第２フラップ部材92は一部を上下ラップ状に配設している。
第１フラップ部材91は、誘導勾配面７を形成するための第１誘導壁部91ｃと、第１誘導壁部91ｃの前後両端縁部に垂下状に設けた第１前後端壁部91ｆ，91ｆ（図面は、第１後端壁部91ｆを図示し、第１前端壁部91ｆは図示省略している。）と、を有している。
第２フラップ部材92は、第１誘導壁部91ｃの裏面側に一部が配設されると共に第１誘導壁部91ｃと平行状に配設される第２誘導壁部92ｃと、第１前後端壁部91ｆ，91ｆよりも誘導勾配面７の前後中心寄り（前後内方側）に配設される第２前後端壁部92ｆ，92ｆ（図面は、第２後端壁部92ｆを図示し、第２前端壁部92ｆは図示省略している。）と、を有している。 3 to 5, a part of the first flap member 91 and the second flap member 92 are arranged in an upper and lower lap shape.
The first flap member 91 includes a first guide wall portion 91c for forming the guide gradient surface 7, and first front and rear end wall portions 91f and 91f provided in a suspended manner at both front and rear edge portions of the first guide wall portion 91c. (The drawing shows the first rear end wall portion 91f, and the first front end wall portion 91f is not shown).
The second flap member 92 includes a second guide wall portion 92c that is partly disposed on the back surface side of the first guide wall portion 91c and is disposed in parallel with the first guide wall portion 91c, and the first front and rear portions. Second front and rear end wall portions 92f and 92f (the drawing shows the second rear end wall portion 92f) disposed closer to the front and rear center (front and rear inner side) of the guide gradient surface 7 than the end wall portions 91f and 91f. The second front end wall portion 92f is not shown).

下端縁退避手段９は、第２フラップ部材92の前後端壁部92ｆ，92ｆ夫々から前後外方へ突設した複数のスライド被案内ローラ94，94を、第１フラップ部材91の第１前後端壁部91ｆ，91ｆ夫々に形成した直線状のガイド長孔93に差し込んで、ガイド長孔93に沿って転動可能とすることで、第１フラップ部材91に対して、第２フラップ部材92を平行状にスライド自在に取り付けている。ガイド長孔93は、第１誘導壁部91ｃの上下幅方向（傾斜方向）Ｗと孔長手方向を平行状として形成している。 The lower edge evacuation means 9 includes a plurality of slide guided rollers 94, 94 projecting forward and backward outward from the front and rear end wall portions 92 f and 92 f of the second flap member 92, and the first front and rear ends of the first flap member 91. The second flap member 92 can be moved with respect to the first flap member 91 by being inserted into the linear guide elongated holes 93 formed in the wall portions 91f and 91f, respectively, and enabling the rolling along the elongated guide holes 93. It is slidably attached in parallel. The guide long hole 93 is formed so that the vertical width direction (inclination direction) W of the first guide wall portion 91c and the hole longitudinal direction are parallel to each other.

さらに、図３及び図５に於て、下端縁退避手段９は、第２フラップ部材92の上部92ａ側の前後端壁部92ｆ，92ｆ夫々から前後外方へ突出する被ガイドローラ95を、第１前後端壁部91ｆ，91ｆよりも前後外方側に配設されると共に第２前後端壁部92ｆ，92ｆに対面状に配設される車体側の固定部11に形成した円弧状のガイド溝部96に差し込んで、誘導板部材79が上下へ揺動すると、被ガイドローラ95をガイド溝部96に案内させて第２フラップ部材92を上下へスライドさせるように構成している。 Further, in FIGS. 3 and 5, the lower edge evacuation means 9 includes guided rollers 95 that protrude from the front and rear end wall portions 92f and 92f on the upper portion 92a side of the second flap member 92 to the front and rear outward. An arcuate guide formed on the vehicle-body-side fixing portion 11 that is disposed on the front and rear outer sides of the front and rear end wall portions 91f and 91f and that is disposed facing the second front and rear end wall portions 92f and 92f. When the guide plate member 79 is inserted into the groove 96 and swings up and down, the guided roller 95 is guided to the guide groove 96 and the second flap member 92 is slid up and down.

車体側の固定部11とは、ホッパー２の下方に配設された壁状部材や補強部材等、車体１の基枠部材に固定されている部位又は部材等が相当する。図例に於ては、各誘導勾配面７（図１参照）の前後両側に配設された鉛直面状の区画壁部（基台枠渡し板壁部）である。 The vehicle body side fixing portion 11 corresponds to a portion or member fixed to the base frame member of the vehicle body 1 such as a wall-like member or a reinforcing member disposed below the hopper 2. In the example shown in the drawing, these are vertical plane partition wall portions (base frame passing plate wall portions) disposed on both front and rear sides of each guiding gradient surface 7 (see FIG. 1).

図３に於て、ガイド溝部96は、下方凸状の円弧型に形成し、その円弧の曲率半径の中心点を、誘導板部材79（第１フラップ部材91及び第２フラップ部材92）の揺動軸心点Ｌｄ´よりも側外方側かつ上側へ偏心させている。或いは、ガイド溝部96の曲率半径の中心点を、揺動軸心点Ｌｄ´よりも側外方側へ偏心させ、曲率半径を小さく設定しても良い。
ここで、誘導板部材79が誘導最上位置の状態で、被ガイドローラ95の中心点Ｐを基準として、一点鎖線で示すように、ガイド溝部96に案内される被ガイドローラ95の中心点Ｐの軌跡を、第２フラップ部材92の上部揺動ガイド軌跡Ｑと呼び、被ガイドローラ95がガイド溝部96に案内されずに移動する場合を想定した中心点Ｐの軌跡を第２フラップ部材92の上部仮想揺動軌跡Ｊと呼ぶ。
第２フラップ部材92が揺動するにつれて、上部誘導ガイド軌跡（ガイド溝部96の溝幅中心線）Ｑは、上部仮想揺動軌跡Ｊに対して、次第に上方へ離間するように設定している。 In FIG. 3, the guide groove portion 96 is formed in a downward convex arc shape, and the center point of the radius of curvature of the arc is set at the guide plate member 79 (the first flap member 91 and the second flap member 92). It is decentered to the outer side and the upper side from the dynamic axis Ld ′. Alternatively, the center point of the radius of curvature of the guide groove 96 may be decentered outwardly from the pivot axis Ld ′ and the radius of curvature may be set small.
Here, in the state where the guide plate member 79 is in the uppermost guide position, the center point P of the guided roller 95 guided by the guide groove portion 96 as shown by a one-dot chain line with the center point P of the guided roller 95 as a reference. The trajectory is called the upper swing guide trajectory Q of the second flap member 92, and the trajectory of the center point P assuming that the guided roller 95 moves without being guided by the guide groove portion 96 is the upper portion of the second flap member 92. This is called a virtual swing locus J.
As the second flap member 92 swings, the upper guide guide locus (groove width center line of the guide groove portion 96) Q is set so as to gradually move upward with respect to the upper virtual swing locus J.

したがって、図３から図６、図７、図８、図９と順次示すように、誘導最上位置の状態から、誘導板部材79が下方へ揺動すると、被ガイドローラ95が、ガイド溝部96によって案内され、被ガイドローラ95の中心点Ｐが上部仮想揺動軌跡Ｊに対して次第に上方へ移動して、第２フラップ部材92を上方へスライドさせ、水平面に対する傾斜角度θが大きくなるにつれて、第１フラップ部材91の下端縁91ｂから第２フラップ部材92の突出寸法Ｓを短くし、誘導板部材79の上下幅寸法Ｅを小さくして、誘導勾配面７の下端縁７ｂを退避させるように構成している。 Accordingly, as shown in FIGS. 3 to 6, 7, 8, and 9, when the guide plate member 79 swings downward from the uppermost guide position, the guided roller 95 is moved by the guide groove 96. As the center point P of the guided roller 95 is gradually moved upward with respect to the upper virtual swing locus J and the second flap member 92 is slid upward, the inclination angle θ with respect to the horizontal plane increases. The projecting dimension S of the second flap member 92 is shortened from the lower end edge 91b of the first flap member 91, the vertical width dimension E of the guide plate member 79 is decreased, and the lower end edge 7b of the guide gradient surface 7 is retracted. doing.

また、下端縁退避手段９は、図９に示すように、誘導板部材79が所定の最大傾斜角度θｅを越えて傾斜しないように誘導最下位置で、第１フラップ部材91に当接して規制するストッパ部16を、車体側の固定部11に設けている。 Further, as shown in FIG. 9, the lower edge evacuation means 9 is in contact with the first flap member 91 at the lowest guide position so that the guide plate member 79 does not tilt beyond the predetermined maximum tilt angle θe. A stopper portion 16 is provided on the fixing portion 11 on the vehicle body side.

図10に一点鎖線で示すように第２フラップ部材92を退避させない場合の下端縁仮想揺動軌跡Ｋに比べて、実線及び二点鎖線で示すように第２フラップ部材92を退避させる場合は、レールｒの近傍まで揺動させても、鉄道走行規則や工事規制等によって規制されている所定の車両下限限界位置Ｙを越えて、車体下方へ突出することが無い。したがって、砕石をレールｒの近傍に滑落させながら、走行することも可能となり、砕石散布作業を迅速に効率良く行うことができる。 Compared to the lower edge virtual swing locus K when the second flap member 92 is not retracted as shown by the one-dot chain line in FIG. 10, when the second flap member 92 is retracted as shown by the solid line and the two-dot chain line, Even if it is swung to the vicinity of the rail r, it does not protrude below the vehicle body beyond a predetermined vehicle lower limit limit position Y regulated by railway travel rules or construction regulations. Accordingly, it is possible to travel while sliding the crushed stone near the rail r, and the crushed stone spraying operation can be performed quickly and efficiently.

また、下端縁退避手段９は、図９、図８、図７、図６、図３と、順次示すように、下端縁７ｂがレールｒ近傍に配設されている誘導最下位置状態から、誘導板部材79が上方へ揺動して、水平面に対する傾斜角度θが小さくなると、被ガイドローラ95の移動に伴って、第２フラップ部材92が自重によって下方へスライド可能となり、第１フラップ部材91の下端縁91ｂから第２フラップ部材92の突出寸法Ｓを長くし、誘導板部材79の上下幅寸法Ｅを大きくして、誘導勾配面７の下端縁７ｂを側外方へ突出させるように構成している。つまり、下端縁退避手段９は下端縁伸縮手段とも言える。
レールｒから離れた様々な位置を狙って、砕石を散布できるため、散布後に、人や作業機械で砕石を移動させる（地均しさせる）作業を、簡略、或いは省略できる。 Further, as shown in FIGS. 9, 8, 7, 6, and 3, the lower edge evacuation means 9 is in the lowest position of the guide where the lower edge 7b is disposed in the vicinity of the rail r. When the guide plate member 79 swings upward and the inclination angle θ with respect to the horizontal plane decreases, the second flap member 92 can slide downward by its own weight as the guided roller 95 moves, and the first flap member 91 The projecting dimension S of the second flap member 92 is lengthened from the lower end edge 91b of the guide plate 79, the vertical width dimension E of the guide plate member 79 is increased, and the lower end edge 7b of the guide gradient surface 7 is configured to project outward. doing. That is, the lower edge evacuation means 9 can also be said to be a lower edge fold expansion / contraction means.
Since the crushed stone can be sprayed aiming at various positions away from the rail r, the work of moving the crushed stone (leveling) by a person or a work machine after the spraying can be simplified or omitted.

次に、図11乃至図15に示す他の実施形態について説明する。
