Description

本発明は、第１線の架線を構成する第１トロリ線に対し、第２線の架線を構成する第２トロリ線を渡らせるため、第１線の架線に取り付けられるわたり線装置に関する。   The present invention relates to a crossover device attached to an overhead line of a first line so as to cross a second trolley line constituting an overhead line of a second line to a first trolley line constituting the overhead line of the first line.

従来、線路の分岐箇所において相互に電気車が運転できるよう、本線トロリ線及び副本線トロリ線を近接させ、パンタグラフによる集電を可能とするわたり線装置が知られている。その代表的なものは図４（Ａ），（Ｂ）に概略的に示すようなわたり線装置１０５である。分岐器付近の本線トロリ線１０１をわたり線装置１０５の下部に取り付け、副本線トロリ線１０３をパイプ部１０７で抑え込むようにして本線トロリ線１０１の上で交差させている。（特許文献１）
特開平６−２２７２９６号公報 2. Description of the Related Art Conventionally, a crossover device is known in which a main line trolley line and a sub main line trolley line are brought close to each other at a branch point of a track so that current can be collected by a pantograph. A typical one is a crossover device 105 as schematically shown in FIGS. 4 (A) and 4 (B). The main trolley wire 101 near the branching unit is attached to the lower part of the crossover device 105, and the sub main trolley wire 103 is crossed on the main trolley wire 101 so as to be suppressed by the pipe portion 107. (Patent Document 1)
JP-A-6-227296

しかし、わたり線装置１０５を取り付けていることによりトロリ線に硬点ができ、局部摩耗の原因となっていた。また、電気車の速度向上と共に、硬点の影響も益々大きくなり、振動疲労特性も悪化するという問題があった。   However, by attaching the cross wire device 105, the trolley wire has a hard point, which causes local wear. In addition, as the speed of the electric vehicle increases, the influence of the hard point increases and the vibration fatigue characteristics deteriorate.

そこで本発明では、上記問題点を解決して、トロリ線に硬点を生じないわたり線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 crossover device that solves the above-described problems and does not produce a hard point on a trolley wire.

上述した問題点を解決するためになされた請求項１に記載の発明は、第１線の架線を構
成する第１トロリ線に対し、第２線の架線を構成する第２トロリ線を渡らせるため、第１
線の架線に取り付けられるわたり線装置において、前記第１トロリ線の上方に配置され、
）前記第１トロリ線の長さ方向に沿って長尺に形成された支持部と、この支持部の長さ方
向の両端部に取り付けられ、第１線の架線を構成するちょう架線又は補助ちょう架線から
前記支持部を吊下する吊下手段とを備え、前記支持部は、前記第１トロリ線の上方であって、前記第１トロリ線の長さ方向に垂直な左右両側に、所定間隔離して平行に設置された２本の支持棒部からなることを特徴とする。 The invention according to claim 1, which has been made to solve the above-described problem, allows the second trolley line constituting the overhead line of the second line to cross over the first trolley line constituting the overhead line of the first line. For the first
In the crossover device attached to the overhead line of the wire, it is disposed above the first trolley wire,
) A support portion that is elongated along the length direction of the first trolley wire, and a hinge wire or an auxiliary hinge that is attached to both ends of the length direction of the support portion and constitutes the overhead wire of the first wire Suspension means for suspending the support part from an overhead line, the support part being above the first trolley line and on both the left and right sides perpendicular to the length direction of the first trolley line. It is characterized by comprising two support bar portions that are spaced apart and placed in parallel.

このわたり線装置は、支持部をちょう架線又は補助ちょう架線に吊り下げて、その吊り下げられた支持部の上に第２トロリ線を載せることで、第２トロリ線と第１トロリ線とを交差させることができる。   This crossover device suspends the support part from the suspension line or the auxiliary support line, and places the second trolley line and the first trolley line on the suspended support part by placing the second trolley line on the suspended support part. Can be crossed.

従ってこのわたり線装置を用いると、従来のわたり線装置と異なり、ちょう架線や補助
ちょう架線に吊下されているため、第１線の第１トロリ線に硬点を生じさせることなく、
第２線の第２トロリ線を渡らせることができる。
また、本発明のわたり線装置は、２本の支持棒部で第２トロリ線を支えているので、１本の支持棒部で第２トロリ線を支える場合に比べ支持棒部の径を強度的に細くすることができる。そのため、第１トロリ線と支持棒部との間隔が広くなり、第１トロリ線が支持棒部に当たる可能性が低くなる。また、２本の支持棒部を、第１トロリ線の上方の、第１トロリ線の長さ方向に垂直な左右両側に、所定間隔離して平行に設置すれば、第１トロリ線が上昇してきたとき支持棒部の間を上昇するので、第１トロリ線が支持棒部に当たる可能性も低くなる。従って、支持棒部を上記のように配置した２本の支持棒部で構成すると、第１トロリ線が支持棒部に当たることを効果的に防止し、パンタグラフが破損することを防止することができる。尚、支持棒部が配置される間隔は、第１トロリ線の径よりも幅広な間隔であることが好ましい。 Therefore, when this crossover device is used, unlike the conventional crossover device, it is suspended from the overhead wire or the auxiliary overhead wire, so that the first trolley wire of the first line does not cause a hard point,
The second trolley line of the second line can be crossed.
Further, since the crossover device of the present invention supports the second trolley wire with two support rod portions, the diameter of the support rod portion is stronger than when the second trolley wire is supported with one support rod portion. Can be made thin. Therefore, the space | interval of a 1st trolley wire and a support bar part becomes wide, and possibility that a 1st trolley line will hit a support bar part will become low. Also, if the two support rods are installed in parallel on the left and right sides perpendicular to the length direction of the first trolley line above the first trolley line, the first trolley line will rise. Since it raises between support bar parts, possibility that a 1st trolley wire will hit a support bar part will also become low. Therefore, if the support bar part is composed of two support bar parts arranged as described above, the first trolley wire can be effectively prevented from hitting the support bar part, and the pantograph can be prevented from being damaged. . In addition, it is preferable that the space | interval which a support bar part is arrange | positioned is a space | interval wider than the diameter of a 1st trolley wire.

次に、支持部の長さ方向の各端部に向かうほど上方に向かって反り上がった肩部が、支持部の長さ方向の両端部の前記第１トロリ線に対向する底部に形成されていることが好ましい。この肩部が形成されていれば、パンタグラフが異常上昇し、支持部を摺るようなことがあっても、パンタグラフが肩部に当たってスムーズに支持部の下に入り込むので、パンタグラフが支持部に引っ掛かって破損することを防止することができる。   Next, shoulder portions that are warped upward toward the respective end portions in the length direction of the support portion are formed on the bottom portions facing the first trolley wires at both ends in the length direction of the support portion. Preferably it is. If this shoulder is formed, even if the pantograph rises abnormally and slides on the support part, the pantograph hits the shoulder part and smoothly enters under the support part, so the pantograph is caught on the support part. It can be prevented from being damaged.

次に、ちょう架線や補助ちょう架線に吊り下げられたとき、支持部の上方でありかつ、ちょう架線又は補助ちょう架線の下方に配置され、支持部の長さ方向に沿って長尺に形成された補助支持部を備えることが好ましい。このわたり線装置では、支持部と補助支持部との間に第２トロリ線を通して、第１トロリ線に第２トロリ線を渡らせる。このようにすれば、第２トロリ線が異常に上昇した場合でも、第２トロリ線がちょう架線又は補助ちょう架線に当たることを防止することができる。また、この補助支持部を備えていると、第１トロリ線と第２トロリ線との間隔が略一定に保たれるので、間隔が空きすぎることによって低いほうのトロリ線（この場合は第１トロリ線）がパンタグラフの下に入り込む割り込みや、パンタグラフの肩に当たって側面が摩耗する偏摩耗を防止することができる。   Next, when suspended on the butterfly wire or the auxiliary hinge wire, it is located above the support portion and below the butterfly wire or the auxiliary hinge wire, and is formed to be long along the length direction of the support portion. It is preferable to provide an auxiliary support portion. In this crossover device, the second trolley wire is passed through the first trolley wire through the second trolley wire between the support portion and the auxiliary support portion. If it does in this way, even when the 2nd trolley line rises abnormally, it can prevent that the 2nd trolley line hits a platform line or an auxiliary platform line. In addition, when the auxiliary support portion is provided, the distance between the first trolley line and the second trolley line is kept substantially constant, so that the lower trolley line (in this case, the first trolley line) It is possible to prevent interruption of the trolley wire) entering under the pantograph and uneven wear in which the side surface is worn by hitting the shoulder of the pantograph.

次に、吊下手段は、支持部と遊動可能に接続されていることが好ましい。吊下手段と支持部とが固定されていると、ちょう架線又は補助ちょう架線が振動しても、支持部に対し吊下手段がちょう架線又は補助ちょう架線の振動に合わせて動くことができないので、ちょう架線又は補助ちょう架線と吊下手段との接合部分で、ちょう架線又は補助ちょう架線にひずみが生じ、ちょう架線又は補助ちょう架線が金属疲労を起す恐れがある。しかし、このように吊下手段と支持部とを遊びを持たせて接続すれば、支持部に対し、吊下手段がちょう架線又は補助ちょう架線の振動に合わせて自由に動くので、ちょう架線又は補助ちょう架線の吊下手段との接合部分でのひずみが防止され、ちょう架線又は補助ちょう架線の金属疲労を防止することがきる。   Next, it is preferable that the suspending means is movably connected to the support portion. If the suspension means and the support section are fixed, the suspension means cannot move with respect to the support section in accordance with the vibration of the suspension line or the auxiliary suspension line even if the suspension line or the auxiliary suspension line vibrates. In addition, there is a possibility that distortion occurs at the joint portion between the overhead wire or the auxiliary overhead wire and the suspension means, and the overhead wire or the auxiliary overhead wire causes metal fatigue. However, if the suspension means and the support portion are connected with play as described above, the suspension means moves freely with respect to the support portion in accordance with the vibration of the suspension line or the auxiliary suspension line. Strain at the joint portion of the auxiliary overhead wire with the suspension means is prevented, and metal fatigue of the overhead wire or the auxiliary overhead wire can be prevented.

以下、本発明を実施するための最良の形態について図面を用いて説明する。
図１は、本実施形態のわたり線装置の正面図、図２は、図１の左側面図、図３は架線の説明図である。ただし、本実施形態のわたり線装置は長尺であるため、中間部分については一部省略してある。 The best mode for carrying out the present invention will be described below with reference to the drawings.
FIG. 1 is a front view of the crossover device of the present embodiment, FIG. 2 is a left side view of FIG. 1, and FIG. However, since the crossover device of the present embodiment is long, a part of the intermediate portion is omitted.

尚、以下の説明で用いられる技術用語のうち、ちょう架線とは、図３（Ａ）に示すように、架線柱と架線柱との間に張られて弓状となり、これにトロリ線を吊下することでトロリ線を真っ直ぐ張るためのものである。このちょう架線とトロリ線との組み合わせのタイプの架線は在来線で主に用いられている。補助ちょう架線とは、図３（Ｂ）に示すように、ちょう架線に吊られて、真っ直ぐに張られ、さらにこの補助ちょう架線にトロリ線を吊下することでトロリ線をより真っ直ぐ張るためのものである。このちょう架線と補助ちょう架線とトロリ線との組み合わせのタイプ（コンパウンド式）の架線は、電流容量が大きく、押上特性に優れているので、新幹線で主に用いられている。また、ちょう架線には、亜鉛めっき鋼より線が主に用いられ、補助ちょう架線には、硬銅より線、トロリ線には、硬銅線、銅覆鋼線等が用いられている。   Of the technical terms used in the following description, the butterfly wire is an arcuate shape that is stretched between the overhead wire column and the overhead wire column as shown in FIG. This is to stretch the trolley wire straight. This type of overhead wire and trolley wire combination type is mainly used for conventional wires. As shown in FIG. 3 (B), the auxiliary overhead line is hung on the overhead line and stretched straight, and further, the trolley line is suspended more straightly by hanging the trolley line on the auxiliary overhead line. Is. This type of overhead wire / auxiliary overhead wire / trolley wire combination type (compound type) overhead wire has a large current capacity and excellent push-up characteristics, and is therefore mainly used in the Shinkansen. Further, galvanized steel strands are mainly used for the overhead wires, hard copper strands are used for the auxiliary platform wires, and hard copper wires and copper-clad steel wires are used for the trolley wires.

本実施形態のわたり線装置１は、本線（本発明の第１線に相当する）の架線を構成する第１トロリ線Ｔ１に対し、副本線（本発明の第２線に相当する）の架線を構成する第２トロリ線Ｔ２を渡らせるため、本線の架線に取り付けられる装置である。このわたり線装置１は、図１，２に示すように、第２トロリ線Ｔ２を支持する支持具５と、この支持具５をちょう架線又は補助ちょう架線αから吊下するための吊下具３と、支持具５の上方に設けられた補助支持具７とを備えている。   The crossover device 1 according to the present embodiment has an auxiliary line (corresponding to the second line of the present invention) with respect to the first trolley line T1 constituting the overhead line of the main line (corresponding to the first line of the present invention). In order to cross the second trolley line T2 that constitutes the main line. As shown in FIGS. 1 and 2, the crossover device 1 includes a support 5 that supports the second trolley wire T <b> 2, and a hanging tool that suspends the support 5 from the overhead line or the auxiliary overhead line α. 3 and an auxiliary support 7 provided above the support 5.

支持具５は、図１、２に示すように、所定間隔離隔して設置された２本の長尺な支持棒５０から構成され、これらは、第１トロリ線Ｔ１の上方であって、第１トロリ線Ｔ１の長さ方向に垂直な左右両側に、所定間隔離して平行に設置される。これら支持棒５０は、図２に示すように、第１トロリ線Ｔ１の径よりも幅広に設置される。   As shown in FIGS. 1 and 2, the support 5 is composed of two long support bars 50 that are spaced apart from each other by a predetermined distance. These support bars 5 are located above the first trolley line T1, On the left and right sides perpendicular to the length direction of one trolley line T1, they are installed in parallel with a predetermined distance. As shown in FIG. 2, these support bars 50 are installed wider than the diameter of the first trolley wire T1.

また、この支持棒５０は、図１に示すように、支持棒５０の長さ方向の各端部に向かうほど上方に向かって反り上がった肩部５２が、支持棒５０の長さ方向の両端部の前記第１トロリ線に対向する底部に形成されている。さらに、この支持棒５０が吊下具３に接続された部分の近傍の表面には、エポキシ樹脂５４が塗布されている。   Further, as shown in FIG. 1, the support bar 50 has shoulders 52 that warp upward toward the ends of the support bar 50 in the length direction. It is formed in the bottom part facing the said 1st trolley line of a part. Further, an epoxy resin 54 is applied to the surface in the vicinity of the portion where the support bar 50 is connected to the hanging tool 3.

吊下具３は、図１に示すように、支持具５の長さ方向の各端部にネジ止めにより取り付けられ、本線のちょう架線又は補助ちょう架線αに巻きつけられた銅板３０を介してちょう架線又は補助ちょう架線を把持している（図２参照）。そしてこの吊下具３は、支持具５を遊動可能に接合され、ちょう架線又は補助ちょう架線αから支持具５を吊下する。   As shown in FIG. 1, the hanging tool 3 is attached to each end portion in the length direction of the support tool 5 by screwing, and passes through a copper plate 30 wound around a main line or an auxiliary overhead line α. It holds the butterfly wire or auxiliary hinge wire (see FIG. 2). And this suspending tool 3 is joined so that the support tool 5 can move freely, and suspends the support tool 5 from the butterfly wire or the auxiliary gantry wire α.

補助支持具７は長尺な棒状に形成されており、その長さ方向の端部は、各吊下具３が支持具５をネジ止めする部分から延設された各アーム部７０に支持されている。そしてこの補助支持具７は、支持具５の上方でありかつ、ちょう架線又は補助ちょう架線αの下方に配置される。   The auxiliary support tool 7 is formed in a long bar shape, and the end portion in the length direction is supported by each arm part 70 extended from the part where each suspension tool 3 screws the support tool 5. ing. And this auxiliary | assistant support tool 7 is arrange | positioned above the support tool 5, and the downward direction of the butterfly line or the auxiliary rack line (alpha).

以上のように構成されたわたり線装置１を用いると次のような作用・効果がある。
このわたり線装置１を用いると、支持具５をちょう架線か補助ちょう架線αに吊下させて、その吊下された支持具５の上に第２トロリ線Ｔ２を載せることで、第２トロリ線Ｔ２と第１トロリ線Ｔ１とを交差させることができる。 When the crossover wire device 1 configured as described above is used, the following operations and effects are obtained.
When the crossover device 1 is used, the second trolley wire T2 is placed on the suspended support tool 5 by suspending the support tool 5 on the hinged line or the auxiliary overhead line α. The line T2 and the first trolley line T1 can be crossed.

従ってこのわたり線装置１を用いると、従来のわたり線装置と異なり、支持具５がちょう架線や補助ちょう架線αに吊下されているため、本線の第１トロリ線Ｔ１に硬点を生じさせることなく、副本線の第２トロリ線Ｔ２を渡らせることができる。   Therefore, when the crossover device 1 is used, unlike the conventional crossover device, the support 5 is suspended from the overhead wire or the auxiliary overhead wire α, so that a hard point is generated in the first trolley wire T1 of the main line. The second trolley line T2 of the secondary main line can be crossed.

また、このわたり線装置１を用いると、肩部５２が形成されているので、パンタグラフが異常上昇し、支持具５を摺るようなことがあっても、パンタグラフが肩部５２に当たって、スムーズに支持具５の下に入り込むので、パンタグラフが支持具５に引っ掛かって破損することを防止することができる。   Further, when the crossover device 1 is used, since the shoulder portion 52 is formed, even if the pantograph rises abnormally and the support 5 is slid, the pantograph hits the shoulder portion 52 and smoothly supports it. Since it enters under the tool 5, it can prevent that a pantograph is caught in the support tool 5 and damaged.

次に、本実施形態のわたり線装置１は、補助支持具７を備えているので、第２トロリ線Ｔ２が異常に上昇しても、ちょう架線又は補助ちょう架線αに当たることを防止することができる。また、この補助支持具７を備えることで、第１トロリ線Ｔ１と第２トロリ線Ｔ２との間隔を略一定に保つことができるので、間隔が空きすぎることによって低いほうのトロリ線（この場合は第１トロリ線）がパンタグラフの下に入り込む割り込みや、パンタグラフの肩に当たって側面が摩耗する偏摩耗を防止することができる。   Next, since the crossover device 1 of the present embodiment includes the auxiliary support 7, even if the second trolley wire T2 rises abnormally, it can be prevented from hitting the overhead wire or the auxiliary overhead wire α. it can. In addition, since the auxiliary support 7 is provided, the distance between the first trolley line T1 and the second trolley line T2 can be kept substantially constant, so that the lower trolley line (in this case) Can prevent interruption of the first trolley line) entering under the pantograph and uneven wear in which the side surface is worn by hitting the shoulder of the pantograph.

次に、本実施形態のわたり線装置１のように、２本の支持棒５０で第２トロリ線Ｔ２を支えれば、１本の支持棒で第２トロリ線を支える場合に比べ支持棒５０の径を強度的に細くすることができる。そのため、第１トロリ線Ｔ１と支持棒５０との間隔が広くなり、第１トロリ線Ｔ１が支持棒５０に当たる可能性が支持棒一本の場合に比べ低くなる。また、２本の支持棒５０を、第１トロリ線Ｔ１の上方の、第１トロリ線Ｔ１の長さ方向に垂直な左右両側に、所定間隔離して平行に設置すれば、第１トロリ線Ｔ１が上昇してきたとき支持棒５０の間を上昇するので、第１トロリ線Ｔ１が支持棒５０に当たる可能性も低くなる。従って、支持棒５０を上記のように配置した２本の支持棒５０で構成すると、第１トロリ線Ｔ１が支持棒５０に当たることを効果的に防止し、パンタグラフが破損することを防止することができる。   Next, if the second trolley wire T2 is supported by the two support rods 50 as in the crossover device 1 of the present embodiment, the support rod 50 can be compared with the case where the second trolley wire is supported by the one support rod. The diameter can be reduced in strength. Therefore, the space | interval of the 1st trolley wire T1 and the support rod 50 becomes wide, and possibility that the 1st trolley wire T1 will contact the support rod 50 will become low compared with the case of one support rod. Further, if the two support rods 50 are installed in parallel at a predetermined interval on the left and right sides perpendicular to the length direction of the first trolley line T1 above the first trolley line T1, the first trolley line T1 is provided. Since the space between the support rods 50 rises when the height has risen, the possibility that the first trolley wire T1 hits the support rod 50 is also reduced. Therefore, when the support bar 50 is composed of the two support bars 50 arranged as described above, it is possible to effectively prevent the first trolley wire T1 from hitting the support bar 50 and to prevent the pantograph from being damaged. it can.

次に、吊下具３と支持具５とを固定すると、第２トロリ線Ｔ２の振動が支持具５を介して吊下具３に直接伝わるので、接合部分等で金属疲労を起す恐れがあるが、本実施形態のわたり線装置１では、吊下具３と支持具５とを遊動可能に接続することで、支持具５の振動が接続部分で吸収されるので、金属疲労を防止することができる。   Next, when the hanging tool 3 and the support tool 5 are fixed, the vibration of the second trolley wire T2 is directly transmitted to the hanging tool 3 via the support tool 5, so that there is a risk of causing metal fatigue at the joint portion or the like. However, in the crossover device 1 of the present embodiment, by connecting the suspending tool 3 and the support tool 5 so as to be freely movable, the vibration of the support tool 5 is absorbed by the connecting portion, thereby preventing metal fatigue. Can do.

吊下具３と支持具５とが固定されていると、ちょう架線又は補助ちょう架線が振動しても、支持具５に対し吊下具３がちょう架線又は補助ちょう架線の振動に合わせて動くことができないので、本線のちょう架線又は補助ちょう架線αと吊下具３との接合部分で、ちょう架線又は補助ちょう架線αにひずみが生じ、ちょう架線又は補助ちょう架線αが金属疲労を起す恐れがある。しかし、このように吊下具３と支持具５とを遊びを持たせて接続すれば、支持具５に対し、吊下具３がちょう架線又は補助ちょう架線αの振動に合わせて自由に動くので、ちょう架線又は補助ちょう架線αの吊下具３との接合部分でのひずみが防止され、ちょう架線又は補助ちょう架線αの金属疲労を防止することがきる。   When the suspension tool 3 and the support tool 5 are fixed, the suspension tool 3 moves with respect to the support tool 5 in accordance with the vibration of the support line or the auxiliary support line even if the suspension line or the auxiliary support line vibrates. As a result, the overhead line or the auxiliary platform line α may be distorted at the joint portion between the main line or the auxiliary platform line α and the hanging tool 3, and the platform line or the auxiliary platform line α may cause metal fatigue. There is. However, if the suspension tool 3 and the support tool 5 are connected with play as described above, the suspension tool 3 can move freely with respect to the support tool 5 in accordance with the vibration of the suspension line or the auxiliary suspension line α. Therefore, distortion at the joint portion of the butterfly wire or the auxiliary gantry wire α with the suspension 3 can be prevented, and metal fatigue of the gantry wire or the auxiliary gantry wire α can be prevented.
