Description

本発明は、鉄道等の車両の車幅方向をｙ軸方向、車高方向をｚ軸方向として、パンタグラフのｚ軸方向上端部に設けられる、ｙ軸方向に長手の集電舟及びそれを備えるパンタグラフに関する。 The present invention provides a current collecting bar elongated in the y-axis direction and provided at the upper end of a pantograph in the z-axis direction, with the vehicle width direction of a vehicle such as a railway being the y-axis direction and the vehicle height direction being the z-axis direction. Regarding the pantograph.

従来、この種の集電舟として、架線に摺接する上面を有して集電するすり板と、ｚ軸方向上方に開放されたｙ軸方向全長に亘る中空部、及びｙ軸方向の一端部と他端部とに位置するすり板支持部を有する舟体と、舟体のすり板支持部の中空部に収納され、すり板をその上面が舟体のｚ軸方向上端から突出するようにｚ軸方向上方に付勢する弾性部材と、舟体の中空部からｙ軸方向の一方と他方との夫々に突出し、且つｚ軸方向下方に折曲するホーンとを備えるものが知られている（例えば、特許文献１参照）。 Conventionally, this type of current collecting bar includes a contact strip that collects current and has an upper surface in sliding contact with overhead wires, a hollow portion that is open upward in the z-axis direction and extends over the entire length in the y-axis direction, and one end in the y-axis direction. and the other end of the boat body having contact strip support portions, and the contact strip is housed in the hollow portion of the contact strip support portion of the boat body so that the upper surface of the contact strip protrudes from the upper end of the boat body in the z-axis direction. It is known to have an elastic member that biases upward in the z-axis direction, and a horn that protrudes from a hollow portion of the boat in one and the other y-axis directions and is bent downward in the z-axis direction. (See Patent Document 1, for example).

また、特許文献１に記載の集電舟では、すり板の上面において渡線等を除く架線に摺接する部分がほぼ平面状に構成されている。ここで、パンタグラフに関する工業規格は、必ずしも国際的に統一されたものが採用されている訳ではなく、国によっては工業規格が異なっている場合もある。例えば、車両走行中に架線とすり板の上面との摺動が途切れたり、また、トンネル内部を走行する際に集電舟がトンネル内壁と接触したりする等の問題があって、特許文献１に記載の集電舟を採用することができない国が実在する。例えば、ヨーロッパの国々の多くは、上記の如くの問題を解消するために、すり板の上面が、上に凸となる形状を有し、且つ少なくともその頂部は曲面から構成されるようにした集電舟を採用している。 In addition, in the current collector bar described in Patent Document 1, the upper surface of the contact strip, which is in sliding contact with the overhead wires other than the connecting wires, is formed in a substantially planar shape. Here, the industrial standards for pantographs are not necessarily internationally unified, and the industrial standards may differ depending on the country. For example, there are problems such as interruption of sliding between the overhead wire and the upper surface of the contact strip while the vehicle is running, and contact of the current collecting bar with the inner wall of the tunnel when running inside the tunnel. There are countries that cannot adopt the current collector described in . For example, in many European countries, in order to solve the above-mentioned problems, the upper surface of the contact strip has a convex shape, and at least the top of the contact strip has a curved surface. It uses an electric boat.

しかしながら、そのような集電舟では、すり板の上面が上に凸となっているが故に、集電舟のｚ軸方向の厚さが特許文献１に記載の集電舟よりも厚くなっており、従って、重量が重く、また、車両走行中の空気抵抗が比較的大きいという別の問題がある。 However, in such a current collector bar, since the upper surface of the contact strip is convex upward, the thickness of the current collector bar in the z-axis direction is larger than that of the current collector bar described in Patent Document 1. Another problem is that it is heavy and therefore has relatively high air resistance while the vehicle is running.

特開２０１７－１６９４１１号公報JP 2017-169411 A

本発明は、以上の点に鑑み、すり板の上面を上に凸となる形状とし、且つ少なくとも頂部を曲面から構成されるようにした集電舟の軽量化及び車両走行中の空気抵抗の低減を図った集電舟及びこの集電舟を備えるパンタグラフを提供することをその課題としている。 In view of the above points, the present invention aims to reduce the weight of the current collector bar and reduce the air resistance during running of the vehicle by making the upper surface of the contact strip convex upward and forming at least the top portion of the curved surface. It is an object of the present invention to provide a current collecting boat and a pantograph equipped with this current collecting boat.

上記課題を解決するために、本発明は、車両の車幅方向をｙ軸方向、車高方向をｚ軸方向として、パンタグラフのｚ軸方向上端部に設けられる、ｙ軸方向に長手の集電舟であって、架線に摺接する上面を有して集電するすり板と、ｚ軸方向上方に開放されたｙ軸方向全長に亘る中空部、及びｙ軸方向の一端部と他端部とに位置するすり板支持部を有する舟体と、舟体のすり板支持部の中空部に収納され、すり板をその上面が舟体のｚ軸方向上端から突出するようにｚ軸方向上方に付勢する弾性部材と、舟体の中空部からｙ軸方向の一方と他方との夫々に突出し、且つｚ軸方向下方に折曲するホーンとを備え、すり板の上面が、上に凸となる形状を有し、且つ少なくともその頂部は曲面から構成されるものにおいて、すり板は、弾性部材によりｚ軸上方に付勢され、すり板支持部に支持された状態で、舟体の中空部にｚ軸方向上下に移動可能に収納され、すり板支持部を除く舟体の底面が、すり板支持部の底面よりもｚ軸方向上方にオフセットしていることを特徴としている。 In order to solve the above-mentioned problems, the present invention provides a current collector elongated in the y-axis direction, which is provided at the upper end of the pantograph in the z-axis direction, where the vehicle width direction is the y-axis direction and the vehicle height direction is the z-axis direction. The boat comprises a contact strip that has an upper surface in sliding contact with the overhead wire and collects electricity, a hollow part that is open upward in the z-axis direction and extends over the entire length in the y-axis direction, and one end and the other end in the y-axis direction. and the slider is housed in the hollow part of the slider supporting portion of the boat, and the slider extends upward in the z-axis direction so that the upper surface of the slider protrudes from the upper end of the boat in the z-axis direction. An elastic member for biasing, and a horn projecting in one direction and the other direction in the y-axis direction from a hollow portion of the boat body and bent downward in the z-axis direction. The contact strip is urged upward in the z-axis direction by an elastic member and is supported by the contact strip support portion, and the hollow portion of the boat body is The bottom surface of the hull excluding the contact strip supporting portion is offset upward in the z-axis direction from the bottom surface of the contact strip supporting portion.

本発明によれば、舟体のすり板支持部を除く部分のｚ軸方向の厚さがすり板支持部よりも薄くなる。このため、集電舟の重量は従来のものよりも軽く、また、車両走行中の空気抵抗が低減される。 According to the present invention, the thickness in the z-axis direction of the portion of the hull excluding the contact strip support portion is thinner than that of the contact strip support portion. Therefore, the weight of the current collecting shoe is lighter than that of the conventional one, and the air resistance during running of the vehicle is reduced.

また、本発明において、車両の車長方向をｘ軸方向として、舟体において、ｘ軸方向一方に位置する第１側面部がｚ軸方向下方に向けてｘ軸方向他方に傾斜し、且つｘ軸方向他方に位置する第２側面部がｚ軸方向下方に向けてｘ軸方向一方に傾斜すると共に、ｚ軸方向上端部に位置する上面部のｘ軸方向一方の第１端縁部がｚ軸方向下方に向けてｘ軸方向一方に傾斜し、且つ当該上面部のｘ軸方向他方の第２端縁部がｚ軸方向下方に向けてｘ軸方向他方に傾斜していることが望ましい。これによれば、上記の如く傾斜する第１側面部、第２側面部、第１端縁部及び第２端縁部により、車両走行中の集電舟の揚力が増大して架線とすり板の上面との摺動がより確実になる。 In the present invention, the longitudinal direction of the vehicle is defined as the x-axis direction, and the first side surface portion located on one side of the boat body in the x-axis direction is inclined downward in the z-axis direction toward the other side in the x-axis direction. The second side surface located on the other side in the axial direction inclines downward in the z-axis direction in one x-axis direction, and the first edge in the x-axis direction of the top surface located at the upper end in the z-axis direction It is desirable that the upper surface portion is inclined downward in one x-axis direction, and that the second edge portion of the upper surface portion on the other x-axis direction is inclined downward in the z-axis direction in the other x-axis direction. According to this, the first side surface portion, the second side surface portion, the first end edge portion, and the second end edge portion which are inclined as described above increase the lifting force of the current collecting bar while the vehicle is running, thereby Sliding with the upper surface of the is more reliable.

The contact strip main body 22 is integrally molded from a conductive material such as carbon, and has a flat bottom surface on the lower side in the z-axis direction. In the upper surface 21, one portion in the y-axis direction across the curved surface 21a is a flat surface 21b that slopes gently downward in the z-axis direction from the curved surface 21a toward one end in the y-axis direction, and the other portion in the y-axis direction. Similarly, a flat surface 21b gently slopes downward in the z-axis direction from the curved surface 21a toward the other end in the y-axis direction. The carrier 23 is a hollow member, and both upper and lower surfaces in the z-axis direction are flat surfaces. A pair of claws 23a are erected on one and the other upper ends of the carrier 23 in the x-axis direction. In the carrier 23, the claw 23a located at one upper end in the x-axis direction is inclined upward in the z-axis direction toward the other x-axis direction, and the claw 23a located at the other upper end in the x-axis direction is inclined upward in the z-axis direction. It is tilted in one direction in the x-axis direction.

また、すり板２には、ｙ軸方向一方端ではｙ軸方向一方に突出し、ｙ軸方向他方端ではｙ軸方向他方に突出する一対の補助ホーン２４が設けられている。補助ホーン２４は、ｚ軸方向下方に向けてｙ軸方向に傾斜する二股の補助ホーン本体２４ａと、補助ホーン２４の突出方向と反対方向に延設されたジョイント２４ｂとを備えている。ジョイント２４ｂの上面は平面から構成され、補助ホーン本体２４ａに近い側に、ｚ軸方向上下に貫通し、並置された２つの第１挿入穴２４ｂ１が設けられている。第１挿入穴２４ｂ１の各１つは、キャリア２３のスタッド６の各１本と対置可能とされている。また、ジョイント２４ｂには、補助ホーン本体２４ａから遠くに位置する第１挿入穴２４ｂ１に隣接して、第１挿入穴２４ｂ１よりも開口面積が大きい第２挿入穴２４ｂ２が設けられている。第２挿入穴２４ｂ２もジョイント２４ｂをｚ軸方向上下に貫通する第２挿入穴２４ｂ２が設けられたジョイント２４ｂのｘ軸方向一方及び他方の側面部には、第２挿入穴２４ｂ２と連通する第１ピン孔２４ｂ３が設けられている。さらに、ジョイント２４ｂでは、第２挿入穴２４ｂ２に隣接し、補助ホーン本体２４ａよりも遠い部分の下面が他の部分の下面よりもｚ軸方向上方にオフセットしている。このようにオフセットした下面に突起状の第１弾性部材ガイド２４ｂ４がｚ軸方向下方に突設されている。このような補助ホーン２４は、キャリア２３のスタッド６の各１本をこれに対置する第１挿入穴２４ｂ１の各１つにｚ軸方向上方より挿入し、ジョイント２４ｂの上面にキャリア２３の下面を重合させて載置し、ｚ軸方向下方から第１挿入穴２４ｂ１の内部にナット７を挿入してスタッド６の下端部にねじ込むことによって、すり板２と連結できる。Further, the contact strip 2 is provided with a pair of auxiliary horns 24 that protrude in one y-axis direction at one end in the y-axis direction and protrude in the other y-axis direction at the other end in the y-axis direction. The auxiliary horn 24 includes a bifurcated auxiliary horn main body 24a inclined downward in the z-axis direction in the y-axis direction, and a joint 24b extending in the direction opposite to the direction in which the auxiliary horn 24 protrudes. The upper surface of the joint 24b is flat, and two first insertion holes 24b1 are provided side by side through the joint 24b in the vertical direction in the z-axis direction on the side closer to the auxiliary horn main body 24a. Each one of the first insertion holes 24 b 1 can be opposed to each one of the studs 6 of the carrier 23 . Further, the joint 24b is provided with a second insertion hole 24b- 2 having a larger opening area than the first insertion hole 24b- 1 adjacent to the first insertion hole 24b-1 positioned far from the auxiliary horn main body 24a. . The second insertion hole 24b2 also communicates with the second insertion hole 24b2 on one side and the other side in the x-axis direction of the joint 24b provided with the second insertion hole 24b2 penetrating the joint 24b vertically in the z-axis direction. A first pin hole 24b3 is provided. Further, in the joint 24b, the lower surface of the portion adjacent to the second insertion hole 24b2 and farther from the auxiliary horn main body 24a is offset upward in the z-axis direction from the lower surface of the other portion. A protruding first elastic member guide 24b4 is provided on the bottom surface offset in this manner so as to protrude downward in the z-axis direction. Such an auxiliary horn 24 is made by inserting each one of the studs 6 of the carrier 23 into each one of the opposing first insertion holes 24b1 from above in the z-axis direction, so that the lower surface of the carrier 23 is attached to the upper surface of the joint 24b. are superposed on each other, and the nut 7 is inserted into the first insertion hole 24b1 from below in the z-axis direction and screwed into the lower end of the stud 6, whereby the contact strip 2 can be connected.

舟体３のすり板支持部３２の内底部には、補助ホーン２４の第２挿入穴２４ｂ２と対置可能な部位に、ブッシュ８がｚ軸方向上方に向けて植設されている。また、補助ホーン２４の第１弾性部材ガイド２４ｂ４と対置可能な部位に突起状の第２弾性部材ガイド３２ｂがｚ軸方向上方に突設されている。さらに、舟体３のｙ軸方向一方端部に位置するすり板支持部３２には、ブッシュ８よりもｙ軸方向一方端寄りの部位に、底面３２ａをｚ軸方向上下に貫通する２つの第３挿入穴３２ｃが設けられている。第３挿入穴３２ｃはｙ軸方向に所定間隔を存して並置されている。A bushing 8 is planted upward in the z-axis direction at a portion of the inner bottom of the contact strip support portion 32 of the boat body 3 where it can face the second insertion hole 24b2 of the auxiliary horn 24. As shown in FIG. Further, a projecting second elastic member guide 32b protrudes upward in the z-axis direction at a portion of the auxiliary horn 24 that can face the first elastic member guide 24b4 . Further, in the contact strip support portion 32 located at one end in the y-axis direction of the boat body 3, two second contact strips penetrating vertically through the bottom surface 32a in the z-axis direction are provided closer to the one end in the y-axis direction than the bush 8. 3 insertion holes 32c are provided. The third insertion holes 32c are arranged side by side with a predetermined interval in the y-axis direction.

ホーン５は弓形に折曲する形状を有し、ｚ軸方向下方に折曲する部分には、ｘ軸方向に貫通する複数の貫通穴５ａが所定の間隔を存して設けられている。貫通穴５ａは、車両走行中に空気が流入及び流出して集電舟１の車両進行方向後方にカルマン渦が発生するのを抑制し、空力騒音の低減に寄与する。ホーン５のｙ軸方向に平行な基部５ｂには、第３挿入穴３２ｃに対置可能な中実部位に、ｚ軸方向上方に向かう非貫通のボルト孔が形成されている。このようなホーン５は、そのボルト孔と第３挿入穴３２ｃとを対置させて基部５ｂをすり板支持部３２ａの内底面上に載置し、ボルト９をｚ軸方向下方から第３挿入穴３２ｃに挿入し、上記ボルト孔にねじ込むことによって舟体３と連結できる。 The horn 5 has an arcuately bent shape, and a plurality of through holes 5a passing through in the x-axis direction are provided at predetermined intervals in the portion bent downward in the z-axis direction. The through-holes 5a suppress the inflow and outflow of air while the vehicle is running, thereby suppressing the generation of Karman vortices behind the current collecting shoe 1 in the direction in which the vehicle travels, thereby contributing to the reduction of aerodynamic noise. A non-penetrating bolt hole extending upward in the z-axis direction is formed in a solid portion of the base portion 5b of the horn 5 parallel to the y-axis direction so as to be opposed to the third insertion hole 32c. The horn 5 is arranged such that the bolt hole and the third insertion hole 32c are opposed to each other, and the base portion 5b is placed on the inner bottom surface of the contact strip support portion 32a. 32c, and can be connected to the boat body 3 by screwing into the bolt holes.

そして、集電舟１は、すり板２に補助ホーン２４が連結され、且つホーン５が舟体３に連結された状態においてすり板２を舟体３に組み付けることによって形成される。すり板２と舟体３との組付けに弾性部材４が用いられると共に、ロッド組１０及びピン１１が用いられる。ロッド組１０は、ｚ軸方向に長手で、ｚ軸方向下端部の外周部にねじ溝が刻設されたロッド本体１０ａと、ロッド本体１０ａのｚ軸方向上端に位置し、補助ホーン２４の第２挿入穴２４ｂ２におけるｘ軸方向の幅以内に収まる大きさを有する頂部１０ｂとを備え、頂部１０ｂにはｘ軸方向に貫通する第２ピン孔１０ｃが設けられている。すり板２と舟体３とを組付ける際には、弾性部材４のｚ軸方向下端部を第２弾性部材ガイド８に外嵌し、ロッド組１０の頂部１０ａを第２挿入穴２４ｂ２の内部に第２ピン孔１０ｃと第１ピン孔２４ｂ３とが連通するように配置する。次いで、ピン１１をｘ軸方向他方から第１ピン孔２４ｂ３、第２ピン孔１０ｃ、第１ピン孔２４ｂ３の順に挿入してすり板２にロッド組１０を取り付け、ロッド本体１０ａをすり板２のｚ軸方向下方に突出させる。この後、補助ホーン２４のジョイント２４ｂ及びすり板２のキャリア２３をｚ軸方向上方から舟体３の中空部３１に挿入する。この時、弾性部材４の上端部が第１弾性ガイド２４ｂ４に外嵌し、弾性部材４はすり板支持部３２の中空部３１に収納され、且つロッド本体１０ａの下端部がブッシュ８の内部に挿入される。この状態において、キャップナット１２をｚ軸方向下方からロッド本体１０ａにねじ込む。キャップナット１２をねじ込むにつれて弾性部材４がジョイント２４ｂとすり板支持部３２との間で圧縮され、弾性部材４はすり板２をｚ軸方向上方に付勢する。こうして、すり板２は、ｚ軸方向上方に付勢されて舟体３の中空部３１に収納されると共に、上面２１が舟体３のｚ軸方向上端から突出し、すり板支持部３２に支持される。このときのすり板２のすり板支持部３２による支持状態は、舟体３の中空部３１でｚ軸方向上下に移動可能であるが、ｘ軸方向及びｙ軸方向への移動はキャップナット１２により制止され、すり板２が舟体３から脱落することはない。また、すり板２のｚ軸方向上下の移動はキャップナット１２のねじ込み具合により制限される。なお、すり板２と舟体３が組付けられた時、各ホーン５は、それに対応する位置の各補助ホーン本体２４ａの二股に分かれた一方部分２４ａ１と他方部分２４ａ２との間にｚ軸方向下方に介在する。The current collecting shoe 1 is formed by assembling the contact strip 2 to the boat body 3 in a state in which the auxiliary horn 24 is connected to the contact strip 2 and the horn 5 is connected to the boat body 3 . An elastic member 4 is used to assemble the contact strip 2 and the boat body 3, and a rod set 10 and a pin 11 are used. The rod set 10 includes a rod body 10a which is long in the z-axis direction and has a thread groove formed on the outer periphery of the lower end in the z-axis direction, and a rod body 10a located at the upper end in the z-axis direction of the rod body 10a. 2. A top portion 10b having a size that fits within the width of the insertion hole 24b2 in the x-axis direction, and a second pin hole 10c that penetrates in the x-axis direction is provided in the top portion 10b. When assembling the contact strip 2 and the boat body 3, the lower end of the elastic member 4 in the z-axis direction is fitted onto the second elastic member guide 8, and the top portion 10a of the rod assembly 10 is inserted into the second insertion hole 24b2. Inside, the second pin hole 10c and the first pin hole 24b3 are arranged so as to communicate with each other. Next, the rod set 10 is attached to the contact strip 2 by inserting the pin 11 from the other side in the x-axis direction into the first pin hole 24b 3 , the second pin hole 10c and the first pin hole 24b 3 in this order, and the rod body 10a is attached to the contact strip. 2 project downward in the z-axis direction. After that, the joint 24b of the auxiliary horn 24 and the carrier 23 of the contact strip 2 are inserted into the hollow portion 31 of the boat body 3 from above in the z-axis direction. At this time, the upper end of the elastic member 4 is fitted to the first elastic guide 24b4, the elastic member 4 is accommodated in the hollow portion 31 of the contact strip support portion 32, and the lower end of the rod body 10a is inside the bush 8. is inserted into In this state, the cap nut 12 is screwed into the rod body 10a from below in the z-axis direction. As the cap nut 12 is screwed, the elastic member 4 is compressed between the joint 24b and the contact strip support portion 32, and the elastic member 4 urges the contact strip 2 upward in the z-axis direction. Thus, the contact strip 2 is urged upward in the z-axis direction and accommodated in the hollow portion 31 of the boat body 3 , and the upper surface 21 protrudes from the upper end of the boat body 3 in the z-axis direction and is supported by the contact strip support portion 32 . be done. At this time, the contact strip 2 is supported by the contact strip support portion 32 so that it can move up and down in the z-axis direction in the hollow portion 31 of the boat body 3. and the contact strip 2 does not drop off from the boat body 3. Further, the vertical movement of the contact strip 2 in the z-axis direction is restricted by the degree of screwing of the cap nut 12 . When the contact strip 2 and the boat body 3 are assembled, each horn 5 is positioned between the bifurcated one portion 24a1 and the other portion 24a2 of each auxiliary horn main body 24a at a corresponding position. It intervenes axially downward.

上記の如くの集電舟１では、すり板支持部３２を除く舟体３の底面３ａが、すり板支持部３２の底面３２ａよりもｚ軸方向上方にオフセットしているので、舟体３のすり板支持部３２を除く部分のｚ軸方向の厚さがすり板支持部３２よりも薄くなる。このため、集電舟１の重量は従来のものよりも軽く、また、車両走行中の空気抵抗が低減される。 In the current collector shoe 1 as described above, since the bottom surface 3a of the boat body 3 excluding the contact strip support portion 32 is offset upward in the z-axis direction from the bottom face 32a of the contact strip support portion 32, The thickness in the z-axis direction of the portion other than the contact strip support portion 32 is thinner than that of the contact strip support portion 32 . Therefore, the weight of the current collecting shoe 1 is lighter than that of the conventional one, and the air resistance during running of the vehicle is reduced.

次に、図３も参照して、集電舟１では、さらに、舟体３において、ｘ軸方向一方に位置する第１側面部３３がｚ軸方向下方に向けてｘ軸方向他方に傾斜し、且つｘ軸方向他方に位置する第２側面部３４がｚ軸方向下方に向けてｘ軸方向一方に傾斜している。また、ｚ軸方向上端部に位置する上面部３５のｘ軸方向一方の第１端縁部３５ａがｚ軸方向下方に向けてｘ軸方向一方に傾斜し、且つ上面部３５のｘ軸方向他方の第２端縁部３５ｂがｚ軸方向下方に向けてｘ軸方向他方に傾斜している。上記の如く傾斜する第１側面部３３、第２側面部３４、第１端縁部３５ａ及び第２端縁部３５ｂにより、車両走行中、ｘ軸方向一方又は他方に向かう空気の流れをｚ軸方向上方と下方とに分離でき、舟体３のすり板支持部３２の厚さがすり板支持部３２以外の部分よりも厚くなっても、すり板支持部３２に直接当たる空気の流れを抑制できる。このため、集電舟１の揚力が増大して架線とすり板２の上面２１との摺動がより確実になる。 Next, referring also to FIG. 3, in the current collecting boat 1, the first side surface portion 33 positioned on one side in the x-axis direction of the boat body 3 is inclined downward in the z-axis direction toward the other side in the x-axis direction. , and the second side surface portion 34 positioned on the other side in the x-axis direction is inclined downward in the z-axis direction toward one side in the x-axis direction. In addition, the first edge portion 35a on one side in the x-axis direction of the upper surface portion 35 positioned at the upper end in the z-axis direction is inclined downward in the z-axis direction in one x-axis direction, and the other edge portion 35a in the x-axis direction of the upper surface portion 35 is inclined downward in the z-axis direction toward the other in the x-axis direction. The first side surface portion 33, the second side surface portion 34, the first end edge portion 35a, and the second end edge portion 35b, which are inclined as described above, allow air to flow in one or the other direction of the x-axis while the vehicle is running. The upper direction and the lower direction can be separated, and even if the thickness of the contact strip support part 32 of the boat body 3 becomes thicker than the part other than the contact strip support part 32, the flow of air directly hitting the contact strip support part 32 can be suppressed. . Therefore, the lifting force of the current collecting shoe 1 is increased, and the sliding between the overhead wire and the upper surface 21 of the contact strip 2 becomes more reliable.

以上、本発明の実施形態について図面を参照して説明したが、本発明はこれに限定されない。上記実施形態では、すり板２に補助ホーン２４が突設されているが、補助ホーン２４はすり板２の上面２１を構成する一部として設けることもでき、また、その形状も二股に分かれたものではなく、ホーン５による渡線から次の架線への誘導をスムーズに行うことができる限り特に限定的ではない。さらに、弾性部材４を用いたすり板２のｚ軸方向上方への付勢を実現する構造も特に限定的ではない。弾性部材４がすり板収納部４からの脱落を防止できる構造であれば任意のものを採用できる。 Although the embodiments of the present invention have been described above with reference to the drawings, the present invention is not limited thereto. In the above-described embodiment, the auxiliary horn 24 protrudes from the contact strip 2, but the auxiliary horn 24 may be provided as a part of the upper surface 21 of the contact strip 2, and its shape is also bifurcated. There is no particular limitation as long as the horn 5 can smoothly guide the crossover line to the next overhead line. Furthermore, the structure that uses the elastic member 4 to urge the contact strip 2 upward in the z-axis direction is not particularly limited. Any structure can be adopted as long as the elastic member 4 can prevent the elastic member 4 from falling off from the contact strip housing portion 4 .
