Description

本発明は、鉄道車両の屋根に搭載されて架線から電力を集電する車両用シングルアーム式パンタグラフに関し、より詳しくは、着雪時の折り畳み不良を効果的に抑制できる構成を備えるものに関する。   The present invention relates to a single-arm pantograph for a vehicle that is mounted on a roof of a railway vehicle and collects electric power from an overhead line, and more particularly, to a device that has a configuration that can effectively suppress a folding failure during snowfall.

この種の車両用シングルアーム式パンタグラフは、例えば特許文献１で知れられている。このものは、鉄道車両の屋根上に碍子を介して配置される台枠に揺動自在に連結される下枠と、この下枠に揺動自在に連結される、集電舟を支持する上枠とを有する枠組と、架線に集電舟が摺接する展開姿勢から枠組を下降させたとき、集電舟が架線から離隔した折畳姿勢に枠組を保つ鉤手段とを備える。ここで、上記車両用シングルアーム式パンタグラフでは、省スペース化等のため、車幅方向に直交する上下方向で上枠と下枠とが互いに重なるように、下枠と上枠とがヒンジを介して揺動自在に連結することが主流となっている（例えば、特許文献２参照）。   This type of single-arm pantograph for a vehicle is known, for example, from Patent Document 1. This is an upper frame that supports a current collector boat that is swingably connected to a lower frame that is swingably connected to a base frame disposed on a roof of a railway vehicle via an insulator. A frame having a frame, and a saddle means that keeps the frame in a folded position in which the current collecting boat is separated from the overhead line when the frame is lowered from the deployed posture in which the current collecting boat is in sliding contact with the overhead line. Here, in the above-described single arm pantograph for a vehicle, for the purpose of space saving, the lower frame and the upper frame are interposed via hinges so that the upper frame and the lower frame overlap each other in the vertical direction perpendicular to the vehicle width direction. It is the mainstream to be able to swing freely (see, for example, Patent Document 2).

このような車両用シングルアーム式パンタグラフは、枠組を構成する部材が少ないため、降雪時に着雪する面積が小さいという利点がある。然し、上記の如く、上下方向で上枠と下枠とが互いに重なるように枠組を構成していると、下枠の外表面に積雪した状態で展開位置から枠組を下降させたときに上枠と下枠との間に雪が挟まり、鉤手段が係合する位置まで枠組を下降することができないという問題が生じる。このため、上枠と下枠との間隔が大きく取れる位置までしか枠組を下降させない等の対策をとることが考えられるが、地上からの車両及び架線の高さ寸法や、折畳姿勢での架線と集電舟との間隔が規格等で定められている状況では、有効な対策にはなり得なかった。   Such a single-arm pantograph for a vehicle has an advantage that the area of snowfall during snowfall is small because there are few members constituting the frame. However, as described above, if the frame is configured such that the upper frame and the lower frame overlap with each other in the vertical direction, the upper frame is lowered when the frame is lowered from the deployed position in a state where snow has accumulated on the outer surface of the lower frame. There is a problem that snow is caught between the frame and the lower frame, and the frame cannot be lowered to the position where the hook means is engaged. For this reason, it is conceivable to take measures such as lowering the frame only to a position where the distance between the upper frame and the lower frame is large, but the height of the vehicle and the overhead line from the ground, and the overhead line in the folded position In a situation where the distance between the boat and the power boat is defined by the standards, it could not be an effective measure.

本発明は、以上の点に鑑み、降雪時に、枠組に積雪した状態でも折畳不良が発生し難い構造を持つ車両用シングルアーム式パンタグラフを提供することをその課題とするものである。   In view of the above, it is an object of the present invention to provide a single-arm pantograph for a vehicle having a structure in which folding failure hardly occurs even when snow falls on a frame during snowfall.

上記課題を解決するために、鉄道車両の屋根に搭載されて架線から電力を集電する本発明の車両用シングルアーム式パンタグラフは、鉄道車両の屋根上に配置される台枠に揺動自在に連結される下枠と、この下枠に揺動自在に連結される、集電舟を支持する上枠とを有する枠組と、この枠組を折畳姿勢に保つ鉤手段とを備え、前記上枠と前記下枠とを車幅方向にオフセットした状態で揺動自在に連結したことを特徴とする。   In order to solve the above problems, the single-arm pantograph for a vehicle of the present invention that is mounted on a roof of a railway vehicle and collects electric power from an overhead line is swingable on a frame arranged on the roof of the railway vehicle. A frame having a lower frame connected to the lower frame, and an upper frame supporting the current collecting boat, which is swingably connected to the lower frame, and a gutter means for keeping the frame in a folded position. And the lower frame are swingably connected in an offset state in the vehicle width direction.

本発明によれば、上枠と下枠とを車幅方向にオフセットした状態で連結したため、降雪時に下枠の外表面に積雪していても、積雪が、下動する上枠と干渉せず、鉤手段が係合する位置まで枠組を確実に下降させることができる。なお、本発明において、「上枠と下枠とを車幅方向にオフセットした状態」とは、上枠と下枠との車幅方向の内側端の間に上下方向から視て間隙を存している場合だけでなく、上枠と下枠との車幅方向の内側端が上下方向でオーバーラップしている場合も含む。   According to the present invention, since the upper frame and the lower frame are connected in an offset state in the vehicle width direction, even if snow falls on the outer surface of the lower frame during snowfall, the snow accumulation does not interfere with the lower frame that moves downward. The frame can be reliably lowered to the position where the hook means is engaged. In the present invention, the “state in which the upper frame and the lower frame are offset in the vehicle width direction” means that there is a gap between the inner end of the upper frame and the lower frame in the vehicle width direction as viewed from the top and bottom. This includes not only the case where the upper frame and the lower frame are overlapped in the vehicle width direction but also in the vertical direction.

また、本発明においては、前記上枠と前記下枠とは断面円形の輪郭を有し、前記上枠と前記下枠との車幅方向の内側端が上下方向でオーバーラップしていることが好ましい。これにより、降雪時に下枠の外表面に着雪する面積が小さくできることで、積雪が、下動する上枠と干渉し難くなる。この場合、枠組の車幅方向の幅を小さくできるため、設置スペースを小さくすることができ、有利である。   Further, in the present invention, the upper frame and the lower frame have a circular cross-sectional outline, and the inner end in the vehicle width direction of the upper frame and the lower frame overlaps in the vertical direction. preferable. Thereby, since the area which snows on the outer surface of a lower frame can be made small at the time of snowfall, it becomes difficult for snow accumulation to interfere with the upper frame which moves down. In this case, since the width of the frame in the vehicle width direction can be reduced, the installation space can be reduced, which is advantageous.

以下、図面を参照して、鉄道車両の屋根に搭載されて架線から電力を集電する本発明の車両用シングルアーム式パンタグラフの実施形態を説明する。以下においては、上、下、左、右や時計周り、反時計周りといった方向を示す用語は図１を基準とする。   Hereinafter, an embodiment of a single-arm pantograph for a vehicle of the present invention that is mounted on a roof of a railway vehicle and collects electric power from an overhead line will be described with reference to the drawings. In the following, terms indicating directions such as up, down, left, right, clockwise, and counterclockwise are based on FIG.

図１〜図３を参照して、ＰＧは、本実施形態のシングルアーム式パンタグラフである。シングルアーム式パンタグラフＰＧは、図外の鉄道車両の屋根上に碍子を介して配置される台枠１を備える。台枠１には、下枠２１が主軸２１ａを介して揺動自在に連結されている。下枠２１の上端にはヒンジ２２を介して上枠２３が揺動自在に連結され、これら下枠２１と上枠２３とが枠組２を構成する。そして、上枠２３により集電舟３が支持されている。上枠２３の下端と台枠１との間には釣合ロッド２４が連結され、ヒンジ２２と集電舟３との間には、枠組２が昇降するときに集電舟３の水平姿勢を保つ舟支えロッド２５が連結されている。集電舟３としては、公知のものが利用できるため、ここでは詳細な説明を省略する。   With reference to FIGS. 1-3, PG is the single arm type pantograph of this embodiment. The single arm type pantograph PG includes a frame 1 disposed on a roof of a railway vehicle (not shown) via an insulator. A lower frame 21 is swingably connected to the underframe 1 via a main shaft 21a. An upper frame 23 is swingably connected to the upper end of the lower frame 21 via a hinge 22, and the lower frame 21 and the upper frame 23 constitute a frame 2. The current collecting boat 3 is supported by the upper frame 23. A balancing rod 24 is connected between the lower end of the upper frame 23 and the base frame 1, and the horizontal posture of the current collecting boat 3 is set between the hinge 22 and the current collecting boat 3 when the frame 2 is raised and lowered. A boat support rod 25 for keeping is connected. Since a known boat can be used as the current collector boat 3, detailed description thereof is omitted here.

台枠１には主バネ４が組み込まれ、この主バネ４の圧縮力が主軸２１ａに外挿固定した第１のカム部材２１ｂに作用するようになっている。これにより、常時は、主軸２１ａに時計周りのトルクが作用して回転することで、枠組２が上昇し、図外の架線に集電舟３が摺接する展開姿勢となる（図１参照）。また、主軸２１ａに外挿固定した第２のカム部材２１ｃには、エアーシリンダ５の駆動ロッド５１が連結されている。これにより、主軸２１ａに、主バネ４の圧縮力に抗してエアーシリンダ５により反時計周りのトルクを作用させて回転することで、展開姿勢にある枠組２が下降し、集電舟３が図外の架線から離隔した折畳姿勢となる。   A main spring 4 is incorporated in the frame 1, and a compressive force of the main spring 4 acts on a first cam member 21 b that is externally fixed to the main shaft 21 a. As a result, the main shaft 21a is normally rotated by a clockwise torque, whereby the frame 2 is raised, and the collector boat 3 is brought into sliding contact with the overhead wire (not shown) (see FIG. 1). The drive rod 51 of the air cylinder 5 is connected to the second cam member 21c that is externally fixed to the main shaft 21a. As a result, the main frame 21a rotates against the compressive force of the main spring 4 by applying a counterclockwise torque by the air cylinder 5, so that the frame 2 in the unfolded position is lowered, and the current collecting boat 3 is The folding position is separated from the overhead line outside the figure.

また、台枠１には、枠組２を折畳姿勢に保つ鉤手段６が配置されている。鉤手段６は、集電舟３に設けた鉤受３１に係合可能な鉤部材６１と、この鉤部材６１が鉤受３１に係合した状態から、時計方向に鉤部材６１を揺動させて鉤部材６１と鉤受３１との係合を解放する駆動手段６２とを備える。駆動手段６２としては、空気シリンダや電磁式鉤外し等、公知のものが利用できるため、ここでは詳細な説明を省略する。   In addition, the frame 1 is provided with a hook means 6 for keeping the frame 2 in a folded posture. The saddle means 6 includes a saddle member 61 that can be engaged with the saddle receiver 31 provided in the current collecting boat 3, and swings the saddle member 61 in a clockwise direction from the state in which the saddle member 61 is engaged with the saddle receiver 31. And a driving means 62 for releasing the engagement between the hook member 61 and the hook receiver 31. As the drive means 62, since a well-known thing can be utilized, such as an air cylinder and an electromagnetic cage, detailed description is abbreviate | omitted here.

ここで、降雪時に、枠組２に積雪した状態でも折畳不良が発生し難い構造にシングルアーム式パンタグラフＰＧを構成する必要がある。本実施形態では、図４（ａ）に示すように、下枠２１と上枠２３とを断面円形の輪郭を有するものとし、下枠２１と上枠２３とを車幅方向にオフセットした状態で下枠２１と上枠２３とをヒンジ２２を介して揺動自在に連結することとした。そして、下枠２１と上枠２３との車幅方向の内側端２１０，２３０を上下方向でオーバーラップさせた。この場合、オーバーラップさせる幅Ｗは、下枠２１及び上枠２３の径等に応じて適宜設定することができる。   Here, at the time of snowfall, it is necessary to configure the single arm type pantograph PG in a structure in which the folding failure hardly occurs even when the frame 2 is covered with snow. In the present embodiment, as shown in FIG. 4A, the lower frame 21 and the upper frame 23 have a circular cross-sectional outline, and the lower frame 21 and the upper frame 23 are offset in the vehicle width direction. The lower frame 21 and the upper frame 23 are slidably connected via the hinge 22. Then, the inner ends 210 and 230 of the lower frame 21 and the upper frame 23 in the vehicle width direction are overlapped in the vertical direction. In this case, the overlapping width W can be appropriately set according to the diameters of the lower frame 21 and the upper frame 23.

上記実施形態によれば、降雪時に下枠２１の外表面に積雪していても、積雪が、下動する上枠２３と干渉せず、鉤部材６１が係合する位置まで枠組２を確実に下降させることができる。その上、上枠２１と下枠２３との輪郭を断面円形としたため、下枠２１の外表面に着雪する面積が小さくなることで、下枠２１と上枠２３との内側端２１０，２３０を上下方向でオーバーラップさせていても、積雪が、下動する上枠２３と干渉し難くすることができる。この場合、枠組２の車幅方向の幅を小さくできるため、設置スペースを小さくすることができ、有利である。   According to the above-described embodiment, even if it is snowing on the outer surface of the lower frame 21 during snowfall, the snow accumulation does not interfere with the upper frame 23 that moves downward, and the frame 2 is securely moved to the position where the eaves member 61 engages. Can be lowered. In addition, since the outline of the upper frame 21 and the lower frame 23 has a circular cross section, the area of snow falling on the outer surface of the lower frame 21 is reduced, so that the inner edges 210 and 230 of the lower frame 21 and the upper frame 23 are reduced. Even if they are overlapped in the vertical direction, it is possible to make it difficult for snow to interfere with the upper frame 23 that moves downward. In this case, since the width of the frame 2 in the vehicle width direction can be reduced, the installation space can be reduced, which is advantageous.

以上、本発明の実施形態について説明したが、本発明は、上記のものに限定されるものではない。上記実施形態では、下枠２１と上枠２３との輪郭を断面円形としたものを例に説明したが、その断面形状は特に限定されるものではない。図４（ｂ）に示すように、下枠２１と上枠２３とが断面矩形の輪郭を有する場合には、下枠２１と上枠２３は、その互いに隣接する内側端２１１，２３１の間に間隙を存して揺動自在に連結されていることが好ましい。   As mentioned above, although embodiment of this invention was described, this invention is not limited to said thing. In the above-described embodiment, an example in which the outline of the lower frame 21 and the upper frame 23 has a circular cross-section has been described as an example, but the cross-sectional shape is not particularly limited. As shown in FIG. 4B, when the lower frame 21 and the upper frame 23 have a rectangular cross-sectional outline, the lower frame 21 and the upper frame 23 are located between the inner ends 211 and 231 adjacent to each other. It is preferable that they are connected so as to be swingable with a gap.
