Description
本発明は、鉄道車両の車体間配線構造とこれに用いる配線支持装置に関するものである。 The present invention relates to an inter-vehicle wiring structure for a railway vehicle and a wiring support device used therefor.
下記の特許文献１、２は、連接された車体間の下部まわりでの電気配線や配管の接続構造を開示している。特許文献１、２は共に、前後車体の固定支持部間での渡り配線を下方に弛ませる従来手法を挙げている。なお、これらの作業で取り扱う配線には、保護チューブの中に多数の配線を収容したケーブルが多用される。 The following Patent Documents 1 and 2 disclose a connection structure of electric wiring and piping around a lower portion between connected vehicle bodies. Both Patent Documents 1 and 2 list conventional methods in which the crossover wiring between the fixed support portions of the front and rear vehicle bodies is loosened downward. In addition, the cable which accommodated many wiring in a protection tube is used abundantly for the wiring handled by these operations.
特許文献１は、連接された車体の端部どうしを共通の台車で連接支持して曲線走行に対応できるようにした構成を採用し、この構成上、車体間では台車が邪魔になって配線を下方に弛ませられないことに対応する技術を開示している。具体的には、台車に前後の車体からの配線を接続する渡り配線を支持して、これら渡り配線の前後端と前後の車体上の配線端とにコネクタを設けておき、それらコネクタ間を、台車から前部車体側、後部車体側に外れた位置で下方に弛ませたジャンパー配線とすることで、台車と前後の車体との曲線走行時の相対移動に追随できるようにしている。 Patent Document 1 adopts a configuration in which the ends of the connected vehicle bodies are connected and supported by a common cart so that it can cope with curved traveling, and on this configuration, the cart becomes a hindrance between the vehicle bodies. A technique corresponding to the fact that it cannot be slackened downward is disclosed. Specifically, supporting the transition wiring connecting the wiring from the front and rear vehicle bodies to the carriage, and providing connectors at the front and rear ends of these transition wirings and the wiring ends on the front and rear vehicle bodies, between these connectors, A jumper wiring that is slackened downward at a position deviated from the carriage toward the front vehicle body side and the rear vehicle body side can follow the relative movement of the carriage and the front and rear vehicle bodies during curved traveling.
特許文献２は、車体間で配線を下方に弛ませるジャンパー配線では、配線数が多くなると、前後の車体間で左右の配線をクロスさせる必要がある場合、配線どうしが干渉してうまく接続できない事態に対応した技術を開示している。具体的には、前後の車体端部の緩衝器に水平時に寄り前後端が回転できるように連結したリンクバーを設けて、このリンクバーに配線箱を支持している。そして、この配線箱の前面に前部車両の配線ケーブルの端部コネクタが接続される前部側コネクタを、配線箱の後面に後部車両の配線ケーブルの端部コネクタが接続される後部側コネクタを、それぞれ設け、これら前、後部側各コネクタ間で渡り配線を予め行い、クロス配線作業でも容易に遂行できるようにしている。 Patent Document 2 states that in jumper wiring that loosens wiring between vehicle bodies, when the number of wirings increases, it is necessary to cross the left and right wirings between the front and rear vehicle bodies, and the wirings interfere with each other and cannot be connected well The technology corresponding to is disclosed. Specifically, a link bar connected to the shock absorbers at the front and rear vehicle body ends so that the front and rear ends can rotate while being horizontal is provided, and the wiring box is supported on the link bar. Then, a front-side connector to which the end connector of the front vehicle wiring cable is connected to the front surface of the wiring box, and a rear-side connector to which the end connector of the rear vehicle wiring cable is connected to the rear surface of the wiring box. These are provided, and crossover wiring is performed in advance between these front and rear connectors so that cross wiring work can be easily performed.
一方、近年いわゆるＬＲＶと称されるバリアフリー化した低床の鉄道車両も、例えば下記特許文献３、４などで知られ路面電車で普及しつつある。低床車両では床下スペースは狭く機器の設置に多くの制限がある。このため主要機器は屋根上に搭載される。この結果、車体の屋根上にはそれら搭載機器間を接続する多くの配線がなされる。 On the other hand, in recent years, barrier-free low-floor railway vehicles called so-called LRVs are also becoming popular in streetcars, for example, known from Patent Documents 3 and 4 below. In low-floor vehicles, the space under the floor is narrow and there are many restrictions on the installation of equipment. For this reason, the main equipment is mounted on the roof. As a result, many wirings for connecting these mounted devices are made on the roof of the vehicle body.
この渡り配線を前後車体の端部に固定支持した支持部間を特許文献１、２が開示するような下方に弛ませる従来のジャンパー配線を採用することができ、これによって、曲線走行時の車体間の相対移動に追随することはできる。 A conventional jumper wiring that loosens the support wire between the support portions fixed to the end portions of the front and rear vehicle bodies downward as disclosed in Patent Documents 1 and 2 can be adopted. It is possible to follow the relative movement between.
しかし、連接された車体間には特許文献４が開示するような貫通路を囲う幌や、特許文献３が開示するような車体間の上部連結機構がある。また、鉄道車両の高さには車両限界があり、低床車両が多く採用される路面電車にあっても、架線との絶縁距離やトンネルとの間の安全距離から見た車両限界がある。 However, there is a hood surrounding the through passage as disclosed in Patent Document 4 and an upper connection mechanism between the vehicle bodies as disclosed in Patent Document 3 between the connected vehicle bodies. In addition, there is a vehicle limit in the height of the railway vehicle, and even in a tram that often employs a low-floor vehicle, there is a vehicle limit in terms of the insulation distance from the overhead line and the safety distance from the tunnel.
このため、渡り配線の下方への弛みは、車体間の幌や上部連結機構などで制限される限界と、車両限界との間のスペースに限られ、大きな弛み量を採りにくい。 For this reason, the downward slack of the crossover wiring is limited to the space between the limit limited by the hood or the upper coupling mechanism between the vehicle bodies and the vehicle limit, and it is difficult to take a large amount of slack.
本発明は、上記の問題に鑑み、高さを抑えたスペース域での配線が可能で、疲労やダメージを受けにくく、曲線走行時の車体間の相対移動に追随できる鉄道車両の車体間配線構造とこれに用いる配線支持装置を提供することを目的としている。 In view of the above problems, the present invention is capable of wiring in a space area with a reduced height, is less susceptible to fatigue and damage, and can follow the relative movement between the vehicle bodies when traveling on a curve, and can follow the relative movement between the vehicle bodies. And it aims at providing the wiring support apparatus used for this.
上記のような目的を達成するために、本発明の鉄道車両の車体間配線構造は、車体間に設けられた貫通路を覆う幌があり、さらに幌の上に車体間の連接部を有し、車体の屋根よりも上に渡り配線を配置する車体間配線構造であって、前後の車体の端部に設置された固定支持具に支持して車体間に渡される渡り配線の途中を、前後のうち何れか一方の車体の端部に片持ち支持され、且つ、前後の車体の端部間で一方の車体寄りの位置において縦軸まわりに回転できるように支持された回転支持具に通して揺動できるように支持し配線したことを特徴としている。 In order to achieve the above object, the inter-vehicle wiring structure for a railway vehicle according to the present invention has a hood covering a through passage provided between the vehicle bodies, and further has a connecting portion between the vehicle bodies on the hood. , a car body between a wiring structure to place over the upper wire than the vehicle roof, the middle of the transition wirings to be passed between the vehicle body and supported by a fixed support which is installed at the ends of the front and rear of the vehicle body, front and rear Through a rotating support that is cantilevered at the end of one of the vehicle bodies and is supported so that it can rotate around the vertical axis between the front and rear vehicle body end positions. It is characterized by being supported and wired so that it can swing.
このような構成では、渡り配線が、前後の車体の端部の固定支持具に支持されながら、途中が縦軸まわりに回転できる回転支持具に通して支持されていることにより、回転支持具の回転を伴い揺動して、回転支持具から車体の端部間で自由に弛んだり、緊張したりできるので、曲線走行時の車体間の相対移動による距離の変化に揺動による迂回や迂回の軽減にて十分に追随できる。特に、回転支持具は渡り配線の途中の下方への弛み防止の下にその揺動域を縦軸まわりのほぼ水平域に規制する。 In such a configuration, the crossover wiring is supported by the fixed support at the ends of the front and rear vehicle bodies, and is supported through the rotation support that can rotate about the vertical axis, so that the rotation support It can be swung with rotation and loosened or tensioned between the ends of the vehicle body from the rotation support, so that the change in distance due to relative movement between the vehicle bodies when traveling on a curve can cause It is possible to follow enough with reduction. In particular, the rotating support restricts the swinging region to a substantially horizontal region around the vertical axis, while preventing the slack downward in the middle of the crossover wiring.
上記において、さらに、回転支持具は、前後の車体の端部の一方に片持ち支持されて、車体の端部間に位置したものとすることができる。 In the above, the rotation support tool can be cantilevered on one of the front and rear end portions of the vehicle body and located between the end portions of the vehicle body.
このような構成では、上記に加え、さらに、車体の端部間の相対移動にかかわらず、回転支持具は車体の端部間にて渡り配線の途中を支持し続けられる。 In such a configuration, in addition to the above, the rotary supporter continues to support the middle of the wiring between the end portions of the vehicle body regardless of the relative movement between the end portions of the vehicle body.
上記において、渡り配線は、その両端がそれぞれ前後の車体の端部上の設置機器にコネクタで接続され、各固定支持具は、対応する車体の端部上で、前記コネクタからの引き回し途中を支持したものとすることができる。 In the above, each of the crossover wires is connected to the installation equipment on the front and rear ends of the vehicle body by connectors, and each fixed support supports the middle of the wiring from the connector on the corresponding end of the vehicle body. Can be.
このような構成では、上記に加え、さらに、固定支持具による渡り配線の途中支持は、コネクタによる接続支持構造に比して渡り配線に対する拘束力が低く、その分だけ揺動する渡り配線に対し働く集中応力を軽減できる。 In such a configuration, in addition to the above, the midway support of the crossover wiring by the fixed support is less constraining to the crossover wiring than the connection support structure by the connector, and the crossover wiring swings correspondingly. Work stress can be reduced.
上記において、さらに、固定支持具は、複数の渡り配線を上下方向よりは車体の幅方向に広がるように配列して支持し、回転支持具は、複数の渡り配線を車体の幅方向よりは上下方向に広がるように配列して支持したものとすることができる。 In the above, the fixed support further supports and arranges the plurality of crossover wires so as to extend in the width direction of the vehicle body from the vertical direction, and the rotation support device supports the plurality of crossover wires in the vertical direction of the vehicle body width direction. It can be arranged and supported so as to spread in the direction.
このような構成では、上記に加え、さらに、固定支持具は、複数の渡り配線を支持するのに、上下方向よりは車体の幅方向に広がるような配列状態にして上下のかさ張りを抑えながら、支持位置が渡り配線の動きの小さな回転支持部の回転を伴う揺動基部であるので過剰負荷や、配線どうしの絡みが生じないようにできる。回転支持具は、固定支持具での支持配列から複数の渡り配線を車体の幅方向よりも上下方向、つまり回転支持具の縦軸方向に広がる配列状態にて支持して、渡り配線が曲線走行時の車体の端部間の相対移動に追随するときの縦軸まわりに屈伸しながら揺動する場合の負荷や配線どうしの絡み合いを軽減することができる。また、上下方向には広がるが許容される高さ域内に限って適用することができる。 In such a configuration, in addition to the above, in addition to the above, the fixed support is arranged in such a manner that it extends in the width direction of the vehicle body rather than in the vertical direction to support a plurality of transition wires, while suppressing the bulkiness of the upper and lower sides, Since the support position is the swing base part with the rotation of the rotation support part where the movement of the wiring is small, it is possible to prevent excessive load and entanglement between the wirings. The rotating support supports a plurality of transition wires from the support arrangement of the fixed support in an arrangement extending in the vertical direction of the vehicle body width direction, that is, in the longitudinal direction of the rotation support tools, and the transition wiring runs in a curved line. It is possible to reduce the entanglement between the load and the wiring when swinging while bending around the vertical axis when following the relative movement between the ends of the vehicle body at the time. In addition, the present invention can be applied only within an allowable height range that spreads in the vertical direction.
本発明の鉄道車両の車体間配線構造の前記いずれか１つの回転支持具は、渡り配線を所定数選択して所定の配列状態にして個別に保持して集合させる複数の配線保持部を有し、上下の支持腕間を連結部材により配線支持スペースを残して一体に連結した支持基体の、前記支持基体の配線支持スペース内に配置されて上下の支持腕間に回転できるように縦軸で支持されて、配線支持装置を構成したものとすることができる。 Any one of the rotation supports of the inter-vehicle wiring structure for a railway vehicle according to the present invention has a plurality of wiring holding portions that select and set a predetermined number of transition wires and hold them individually in a predetermined arrangement state. A support base that is integrally connected between the upper and lower support arms with a connecting member leaving a wiring support space, is arranged in the wiring support space of the support base and is supported on the vertical axis so that it can rotate between the upper and lower support arms. Thus, the wiring support device can be configured.
このような構成では、上記に加え、さらに、下側の支持腕を取り付け座にして、前後の車体の端部の一方からそれらの間に張り出させた片持ち支持部材の張り出し端に取り付けることにより、支持基体を端部間に位置させられる。そこで、支持基体の配線支持スペースに縦軸まわりに回転できるように支持された回転支持具の各配線保持部に、所定数選択した渡り配線の途中を所定数選択して所定の配列状態に保持して集合させれば、集合保持した分の渡り配線が、前後の車体の端部への固定支持具による支持点間で、回転支持具の回転を伴い揺動して、回転支持具から車体の端部との間で自由に弛んだり、緊張したりできるので、曲線走行時の車体間の相対移動による距離の変化に揺動による迂回や迂回の軽減にて十分に追随できる。また、回転支持具は渡り配線の途中が下方に弛まないように支持しながら、揺動域を縦軸まわりのほぼ水平域に規制する。 In such a configuration, in addition to the above, the lower support arm is used as a mounting seat, and is attached to the overhanging end of the cantilevered support member protruding between one of the front and rear end portions of the vehicle body. Thus, the support base can be positioned between the end portions. Therefore, a predetermined number of transition wires selected in a predetermined number are selected and held in a predetermined arrangement state in each wiring holding portion of the rotation support supported so as to be able to rotate around the vertical axis in the wiring support space of the support base. As a result, the crossover wiring corresponding to the collected and held rocks with the rotation of the rotary supporter between the support points by the fixed supporter to the front and rear ends of the vehicle body, and from the rotary supporter to the vehicle body. Since it can be freely slackened or tensioned with the end of the vehicle, it is possible to sufficiently follow the change in the distance due to the relative movement between the vehicle bodies during curve driving by detouring by swinging or reducing detouring. In addition, the rotation support member restricts the swinging region to a substantially horizontal region around the vertical axis while supporting the intermediate wiring so that it does not loosen downward.
本発明のそれ以上の目的および特徴は、以下の詳細な説明および図面の記載によって明らかになる。本発明の各特徴はそれ単独で、あるいは可能な限り複合して、組み合わせ採用することができる。 Further objects and features of the present invention will become apparent from the following detailed description and drawings. Each feature of the present invention can be used alone or in combination as much as possible.
本発明の鉄道車両の車体間配線構造によれば、渡り配線は、前後の車体の端部の固定支持具による支持点間の途中が縦軸まわりに回転できる回転支持具に通して支持され、曲線走行時の車体間の相対移動による距離の変化に応動して回転支持具の回転を伴い揺動して、車体の端部間の近接には弛んで、離間には緊張することで十分に追随できる。特に、回転支持具は渡り配線の途中が下方に弛まないように支持しながら、その揺動域を縦軸まわりのほぼ水平域に規制するので、渡り配線の前記曲線走行時の車体の端部間の相対移動に応動する挙動の高さスペースを小さく抑えられる。 According to the inter-vehicle wiring structure of the railway vehicle of the present invention, the transition wiring is supported through a rotation support that can rotate about the vertical axis in the middle between the support points by the fixed support at the ends of the front and rear vehicle bodies, It is sufficient to swing with the rotation of the rotation support in response to the change in distance due to relative movement between the vehicle bodies when traveling on a curve, loosen in the proximity between the ends of the vehicle body, and tension in the separation You can follow. In particular, the rotary supporter supports the middle of the crossover wiring so that it does not sag downward, and restricts its swinging area to a substantially horizontal region around the vertical axis. The height space of the behavior that responds to relative movement between them can be kept small.
以下、本発明の実施の形態に係る鉄道車両の車体間配線構造の１つの具体例について図１〜図８を参照しながら具体的に説明する。なお、以下の説明は本発明の具体例であって特許請求の範囲の記載事項を限定するものではない。 Hereinafter, one specific example of the inter-vehicle wiring structure for a railway vehicle according to the embodiment of the present invention will be specifically described with reference to FIGS. The following description is a specific example of the present invention, and does not limit the matters described in the claims.
本実施の形態の鉄道車両の車体間配線構造は、図１、図２に示すように、連接された前後の車体１、２の連接端部１ａ、２ａに設置された固定支持具３、４に支持して車体１、２間に渡される渡り配線５、６の途中を、連接端部１ａ、２ａ間に縦軸７まわりに回転できるように支持された回転支持具８に通して揺動できるように支持し配線するものとしている。 As shown in FIGS. 1 and 2, the inter-vehicle wiring structure for a railway vehicle according to the present embodiment includes fixed support members 3 and 4 installed at the connecting end portions 1a and 2a of the front and rear vehicle bodies 1 and 2 connected to each other. Oscillates in the middle of the connecting wires 5 and 6 passed between the vehicle bodies 1 and 2 through a rotating support 8 supported so as to be rotatable around the longitudinal axis 7 between the connecting end portions 1a and 2a. Supporting and wiring as possible.
このように渡り配線５、６が、前後の車体１、２の連接端部１ａ、２ａの固定支持具３、４に支持されながら、途中が縦軸７まわりに回転できる回転支持具８に通して支持されていることにより、回転支持具８の回転を伴い揺動して、回転支持具８から車体１、２の連接端部１ａ、２ａ間で自由に弛んだり、緊張したりできる。これにより、曲線走行時の車体１、２間の相対移動による距離の変化に揺動による迂回(弛み)や迂回の軽減(緊張)にて十分に追随できる。特に、回転支持具８は渡り配線５、６の途中の下方への弛み防止の下にその揺動域を縦軸７まわりのほぼ水平域に規制する。 In this way, the crossover wires 5 and 6 are passed through the rotary support 8 that can be rotated about the vertical axis 7 while being supported by the fixed supports 3 and 4 of the connecting ends 1a and 2a of the front and rear vehicle bodies 1 and 2. By being supported, the rotary support tool 8 can be swung with the rotation of the rotary support tool 8, so that the rotary support tool 8 can freely loosen or be tensioned between the connecting end portions 1 a and 2 a of the vehicle bodies 1 and 2. Thereby, it is possible to sufficiently follow the change in the distance due to the relative movement between the vehicle bodies 1 and 2 during the curve traveling by detouring (sagging) by swinging and reduction of detouring (tension). In particular, the rotary support 8 restricts its swinging range to a substantially horizontal range around the vertical axis 7 while preventing the slack in the middle of the crossover wires 5, 6.
したがって、このような車体間配線構造例によれば、渡り配線５、６は、前後の車体１、２の連接端部１ａ、２ａの固定支持具３、４による支持点Ａ、Ｂ間の途中が縦軸７まわりに回転できる回転支持具８に通して支持され、曲線走行時の車体１、２間の相対移動による距離の変化に応動して回転支持具８の回転を伴い揺動して、車体１、２の連接端部１ａ、２ａ間の近接には弛んで、離間には緊張することで十分に追随できる。特に、回転支持具８は渡り配線５、６の途中が下方に弛まないように支持しながら、その揺動域を縦軸７まわりのほぼ水平域に規制するので、渡り配線５、６の前記曲線走行時の車体１、２の連接端部１ａ、２ａ間の相対移動に応動する挙動の高さスペースを小さく抑えられる。従って、渡り配線５、６の配列を車体１、２の幅方向よりも上下方向に大きくする場合の許容範囲が増大する。 Therefore, according to such an inter-vehicle wiring structure example, the transition wirings 5 and 6 are provided between the supporting points A and B by the fixed support members 3 and 4 of the connecting end portions 1a and 2a of the front and rear vehicle bodies 1 and 2. Is supported through a rotation support tool 8 that can rotate about the vertical axis 7 and swings with the rotation of the rotation support tool 8 in response to a change in distance due to relative movement between the vehicle bodies 1 and 2 when traveling along a curve. The vehicle body 1 and 2 can be sufficiently followed by loosening in the proximity between the connecting end portions 1a and 2a and tensioning in the separation. In particular, since the rotation support 8 supports the transition wires 5 and 6 so that the middle of the transition wires 5 and 6 does not sag downward, the swinging region is restricted to a substantially horizontal region around the vertical axis 7. The height space of the behavior responding to the relative movement between the connecting end portions 1a and 2a of the vehicle bodies 1 and 2 at the time of curve traveling can be suppressed to be small. Therefore, the allowable range when the arrangement of the crossover wirings 5 and 6 is made larger in the vertical direction than the width direction of the vehicle bodies 1 and 2 is increased.
ここで、図示例の車体間配線構造を適用した鉄道車両は、特許文献４が開示するような連接構造を採用している。具体的には、台車で支持された車体１と支持する台車のない車体２との間に、少なくとも相互間のヨーイングを許容する軸受を介し連結して、台車のない車体２を台車のある車体１に支持するように下部間を連接した図示しない下部連接部と、各車体１、２の連接端部１ａ、２ａの上部間に、図１、図３〜図５に示すような一方の例えば車体１に固定された固定ブラケット１３と、他方の例えば車体２に固定された固定ブラケット１０との間で左右２箇所が球面軸受やゴムブッシュ１５などを介し上下揺動できるように支持した可動ブラケット１４とを、球面軸受やゴムブッシュ１５を介し連結して車体１、２の上部間を連接した第１の上部連接部１６を備えている。 Here, the railway vehicle to which the inter-vehicle wiring structure of the illustrated example employs a connection structure as disclosed in Patent Document 4. Specifically, the vehicle body 1 supported by the carriage and the vehicle body 2 without the carriage to be supported are connected via a bearing that allows at least yawing between them, and the vehicle body 2 without the carriage is connected to the vehicle body with the carriage. 1 between the lower connecting portion (not shown) connected between the lower portions so as to be supported by 1 and the upper ends of the connecting end portions 1a and 2a of the vehicle bodies 1 and 2, for example, as shown in FIGS. A movable bracket supported so that two left and right portions can swing up and down via a spherical bearing, a rubber bush 15 or the like between a fixed bracket 13 fixed to the vehicle body 1 and the other fixed bracket 10 fixed to the vehicle body 2, for example. 14 is connected via a spherical bearing or a rubber bush 15 to connect the upper portions of the vehicle bodies 1 and 2 to each other.
図示例では、さらに、第１の上部連接部１６の左右でも、ブラケット１７、１７間をヨーダンパ１８により球面軸受１９を介し連結した第２の連接部２１をも有し、車体１、２間が下部連接部での軸受、および上部連接部１６が与える支点まわりでの互いのヨーイング動作を第２の連接部２１がそのダンパー特性に従って抑えることができるものとしている。その結果、車両の高速走行時の走行性、安定性を高める。 In the illustrated example, the left and right sides of the first upper connecting part 16 also have a second connecting part 21 in which the brackets 17 and 17 are connected via a spherical bearing 19 by a yaw damper 18. It is assumed that the second connecting portion 21 can suppress the yawing operation around the fulcrum provided by the bearing at the lower connecting portion and the upper connecting portion 16 according to the damper characteristics. As a result, the running performance and stability of the vehicle during high speed running are improved.
このような鉄道車両との関係から、渡り配線５、６の下側の配線環境としては、図１、図３〜図５に示すように、連接端部１ａ、２ａ間に貫通路を囲う幌２２があり、さらにその上に、第１、第２の連接部１６、２１があり、渡り配線５、６の下方への設置域、挙動域に制限を受ける。一方、上側の作業環境は既述の通り車両限界によって決まっており、変えられない。なお、屋根上には集電舟を昇降させるパンタグラフ２３も位置しているが、平面視して車体の幅方向に中央配置されるので、これを図２に示すように左右に避けて配線すればよいので問題にならない。 From such a relationship with the railway vehicle, the lower wiring environment of the transitional wires 5 and 6 is a hood that surrounds the through passage between the connecting end portions 1a and 2a as shown in FIGS. 22, and further there are first and second connecting portions 16, 21, which are restricted by the installation area and the behavior area below the crossover wires 5, 6. On the other hand, as described above, the upper working environment is determined by the vehicle limit and cannot be changed. Although the pantograph 23 for raising and lowering the current collector boat is also located on the roof, the pantograph 23 is arranged in the center in the width direction of the vehicle body in a plan view. It doesn't matter because it just needs to.
このような配線環境では、下側の作業環境は車体１、２の屋根よりも高くなってしまうので、幌２２があるだけの鉄道車両の場合に比べ、上下方向の配線域は極端に狭まる。しかし、上記のように渡り配線５、６が曲線走行時の車体の連接端部１ａ、２ａの相対移動に縦軸まわりの水平スペースでの揺動にて追随する結果、多数の渡り配線５、６を車体１、２の幅方向よりは上下方向に広く配列する配線を実現しやすい。 In such a wiring environment, the lower working environment is higher than the roofs of the vehicle bodies 1 and 2, so that the vertical wiring area is extremely narrow compared to the case of a railway vehicle having only the hood 22. However, as described above, the transition wires 5 and 6 follow the relative movement of the connecting end portions 1a and 2a of the vehicle body when traveling in a curve by swinging in a horizontal space around the vertical axis. It is easy to realize a wiring in which 6 is arranged wider in the vertical direction than the width direction of the vehicle bodies 1 and 2.
渡り配線５、６は、保護ホース（図示せず）内に信号配線や電源配線を多数収容した２５Ｖ程度の弱電気配線５と、メインの空調用４００Ｖ程度、７５０Ｖ程度の強電気配線６とによって互いがパンタグラフ２３を左右に避けて離れた個別の経路で配線することで、強電気配線６から弱電気配線５へのノイズの影響を防止している。いずれにしても、それらの両端がそれぞれ前後の車体１、２の連接端部１ａ、２ａ上の図１、図２に示す設置機器１１、１１間、１２、１２間に雌雄のコネクタ９で接続され、各固定支持具３、４は、対応する車体１の連接端部１ａ、２ａ上で、前記コネクタ９からの引き回し途中を支持したものとしている。 The transition wires 5 and 6 are composed of a weak electric wire 5 of about 25V in which many signal wires and power supply wires are housed in a protective hose (not shown), and a strong electric wire 6 of about 400V and 750V for the main air conditioning. By wiring each other by a separate route away from the pantograph 23 on the left and right, the influence of noise from the strong electrical wiring 6 to the weak electrical wiring 5 is prevented. In any case, both ends are connected by male and female connectors 9 between the installation devices 11, 11 and 12, 12 shown in FIGS. 1 and 2 on the connecting end portions 1a, 2a of the front and rear vehicle bodies 1, 2, respectively. In addition, each of the fixed support members 3 and 4 is supported on the connecting end portions 1 a and 2 a of the corresponding vehicle body 1 while being routed from the connector 9.
このような、固定支持具３、４による渡り配線５、６の途中支持は、コネクタ９によるハードな接続支持構造に比して渡り配線５、６に対する拘束力を樹脂クリート２４などによる弾性支持などにて低くすることができ、その分だけ揺動する渡り配線５、６に対しその揺動時に働く集中応力を軽減できる。 Such intermediate support of the transition wires 5 and 6 by the fixed support members 3 and 4 has a restraining force on the transition wires 5 and 6 as compared with a hard connection support structure by the connector 9 and elastic support by the resin cleat 24 or the like. The concentration stress acting at the time of swinging can be reduced with respect to the transition wires 5 and 6 that swing by that amount.
回転支持具８は、前後の車体１、２の連接端部１ａ、２ａの一方に片持ち支持されて、車体１、２の連接端部１ａ、２ａ間に位置したものとしている。これにより、車体１、２の連接端部１ａ、２ａ間の相対移動にかかわらず、回転支持具８は車体１、２の連接端部１ａ、２ａ間にて渡り配線５、６の途中を可動部のない簡単な支持構造にて支持し続けられる。具体的には、前記固定ブラケット１３を片持ち支持部材３１に共用して、回転支持具８を片持ち支持し、車体１、２の連接端部１ａ、２ａ間に位置させながら、連接端部１ａ、２ａ間の相対移動に影響しないようにしている。しかし、固定ブラケット１３のような既設部材がないような場合は、専用の片持ち支持部材３１を用い、連接端部１ａ、２ａの一方に基部を取り付け、先端部に回転支持具８を支持すればよい。 The rotation support 8 is cantilevered by one of the connecting end portions 1a, 2a of the front and rear vehicle bodies 1, 2 and is positioned between the connecting end portions 1a, 2a of the vehicle bodies 1, 2. As a result, regardless of the relative movement between the connecting end portions 1a and 2a of the vehicle bodies 1 and 2, the rotary support 8 can move in the middle of the wiring lines 5 and 6 between the connecting end portions 1a and 2a of the vehicle bodies 1 and 2. It can continue to be supported by a simple support structure with no parts. Specifically, the fixed bracket 13 is shared by the cantilever support member 31, the rotation support 8 is cantilevered, and the connection end portion is positioned between the connection end portions 1 a and 2 a of the vehicle bodies 1 and 2. The relative movement between 1a and 2a is not affected. However, when there is no existing member such as the fixed bracket 13, use a dedicated cantilever support member 31, attach a base to one of the connecting end portions 1a, 2a, and support the rotary support 8 at the tip. That's fine.
回転支持具８は、図７に例示するように、渡り配線５、６を所定数選択して所定の配列状態にして個別に保持して集合させる既に公知な複数の配線保持部３２を有し、上下の支持腕３３、３４間を連結部材３５により配線支持スペース３６ａを残して一体に連結した支持基体３６の、前記配線支持スペース３６ａ内に配置されて上下の支持腕３３、３４間に回転できるように縦軸７で支持されて、配線支持装置３７を構成したものとしている。 As illustrated in FIG. 7, the rotary support 8 has a plurality of already-known wiring holding portions 32 that select a predetermined number of the jumper wirings 5 and 6, hold them individually in a predetermined arrangement state, and collect them together. The support base 36, which is integrally connected between the upper and lower support arms 33 and 34 with the connecting member 35 leaving the wiring support space 36a, is disposed in the wiring support space 36a and rotates between the upper and lower support arms 33 and 34. It is assumed that the wiring support device 37 is configured by being supported by the vertical axis 7 so as to be able to.
これにより、下側の支持腕３４を取り付け座にして、連接される車体１、２の連接端部１ａ、２ａの一方、具体的には連接端部１ａからそれらの間に張り出させた片持ち支持部材３１、つまりこれが共用する固定ブラケット１３の張り出し端に、例えば図５、図６に示す配線支持装置３７に通した図１、図３に示すように螺子（図示せず）にてねじ止めして取り付けることにより、支持基体を連接端部１ａ、２ａ間に位置させられる。 As a result, the lower support arm 34 is used as a mounting seat, and one of the connecting end portions 1a and 2a of the vehicle bodies 1 and 2 to be connected, specifically, the piece projecting between them from the connecting end portion 1a. Screwed with a screw (not shown) as shown in FIGS. 1 and 3, for example, through the wiring support device 37 shown in FIGS. 5 and 6 at the protruding end of the holding support member 31, that is, the fixed bracket 13 shared by the holding support member 31 By fixing and attaching, the support base can be positioned between the connecting end portions 1a and 2a.
そこで、支持基体３６の配線支持スペース３６ａに縦軸まわりに回転できるように支持された回転支持具８の各配線保持部３２に、所定数選択した渡り配線の途中を所定数選択して、図１、図２、図７に示すように所定の配列状態に保持して集合させれば、集合保持した分の渡り配線５、６が、前後の車体１、２の連接端部１ａ、２ａへの固定支持具３、４による支持点Ａ、Ｂ間で、回転支持具８の回転を伴い揺動できるようになる。 Therefore, a predetermined number of transition wires selected in a predetermined number are selected for each wiring holding portion 32 of the rotation support 8 supported so as to be able to rotate around the vertical axis in the wiring support space 36a of the support base 36. 1, FIG. 2 and FIG. 7, if held and assembled in a predetermined arrangement state, the crossover wires 5 and 6 corresponding to the collected and held are connected to the connecting end portions 1a and 2a of the front and rear vehicle bodies 1 and 2, respectively. It becomes possible to swing with the rotation of the rotary support 8 between the support points A and B by the fixed supports 3 and 4.
したがって渡り配線５、６は、既述のように回転支持具８から車体１、２の連接端部１ａ、２ａとの間で自由に弛んだり、緊張したりできるので、曲線走行時の車体１、２間の相対移動による距離の変化に揺動による迂回や迂回の軽減にて十分に追随できる。また、回転支持具８は渡り配線５、６の途中が下方に弛まないように支持しながら、揺動域を縦軸７まわりのほぼ水平域に規制するようになる。 Therefore, the crossover wires 5 and 6 can freely loosen or be tensioned between the rotation support 8 and the connecting end portions 1a and 2a of the vehicle bodies 1 and 2 as described above. It is possible to sufficiently follow the change in distance due to relative movement between the two by detouring by swinging or reducing detouring. In addition, the rotation support 8 regulates the swinging range to a substantially horizontal range around the vertical axis 7 while supporting the intermediate wirings 5 and 6 so that the intermediate wires 5 and 6 are not slackened downward.
ここで、縦軸７は支持基体３６の側にあってもよいが、図示例では回転支持具８に設けてあり、しかも、配線保持部３２の配列の自由度を高めるために、上端と下端とに突設している。固定支持具８の各配線保持部３２は、既に知られる２つ割のゴムブッシュ３２ａよりなり、行方向、列方向に所定数を選択して所定の配列状態に保持されるようにしている。 Here, the vertical axis 7 may be on the support base 36 side, but in the illustrated example, it is provided on the rotary support 8, and in order to increase the degree of freedom of the arrangement of the wiring holding portions 32, the upper end and the lower end are provided. And project. Each wiring holding portion 32 of the fixed support 8 is composed of the already known two-part rubber bush 32a, and a predetermined number is selected in the row direction and the column direction so as to be held in a predetermined arrangement state.
この保持のために、回転支持具８は、配線保持部３２を、１列を含む適数列挟持する一対の挟持板８ａ、８ｂと、この挟持のためにこれら挟持板８ａ、８ｂを列方向に締結するボルト・ナット対４１と、を有している。ボルト・ナット対４１は、挟持板８ａ、８ｂ間に挟持される配線保持部３２の１行を含む適数行の上下配列域の上下位置と、上下配列境界位置とに位置して、配列される配線保持部３２を上下から挟持するようにしている。 For this holding, the rotating support 8 includes a pair of clamping plates 8a and 8b that clamp the wiring holding part 32 in an appropriate number of rows including one row, and the clamping plates 8a and 8b in the column direction for clamping. A bolt-nut pair 41 to be fastened. The bolt and nut pair 41 is arranged at an upper and lower position of an appropriate number of upper and lower arrangement areas including one line of the wiring holding portion 32 held between the holding plates 8a and 8b and an upper and lower arrangement boundary position. The wiring holding part 32 is sandwiched from above and below.
このボルト・ナット対４１による上下からの保持のため、配線保持部３２をなすゴム又は樹脂クリート３２ａの行配列方向の両面に、分割境界を跨ぐ方向の位置決め凹部３２ｂをボルト・ナット対４１の半周面と嵌り合うように形成している。列方向に配列された配線保持部３２の大きさが影響するなどして、隣接のものどうしの弾性が伝播し渡り配線５、６の支持が甘くなりすぎるきらいがある場合は、図７に示すように列方向の配列境界に弾性分断用の金属などよりなる境界板４２を介在させるのがよい。このような配線保持構造は、既述の固定支持具３、４においても同様に適用される。 In order to hold the bolt / nut pair 41 from above and below, the positioning recesses 32b extending across the dividing boundary are formed on both sides of the row arrangement direction of the rubber or resin cleat 32a forming the wiring holding portion 32 in the half circumference of the bolt / nut pair 41. It is formed to fit the surface. FIG. 7 shows the case where the elasticity of the adjacent ones propagates due to the influence of the size of the wiring holding portions 32 arranged in the column direction and the support of the crossover wirings 5 and 6 tends to become too sweet. Thus, it is preferable to interpose the boundary plate 42 made of elastic dividing metal or the like at the array boundary in the column direction. Such a wiring holding structure is similarly applied to the fixed supports 3 and 4 described above.
特に、図示例では、固定支持具３、４は図１、図２に示すように、複数の渡り配線５、６を上下方向よりは車体１、２の幅方向に広がるように配列して支持し、回転支持具８は、複数の渡り配線５、６を車体１、２の幅方向よりは上下方向に広がるように配列して支持している。 In particular, in the illustrated example, as shown in FIGS. 1 and 2, the fixed supports 3 and 4 support a plurality of crossover wires 5 and 6 arranged so as to extend in the width direction of the vehicle bodies 1 and 2 rather than in the vertical direction. The rotation support tool 8 supports a plurality of crossover wires 5 and 6 arranged so as to extend in the vertical direction rather than the width direction of the vehicle bodies 1 and 2.
これにより、固定支持具３、４は、複数の渡り配線５、６を支持するのに、上下方向よりは車体１、２の幅方向に広がるように配列状態にして上下のかさ張りを抑えながら、支持位置が渡り配線５、６の動きの小さな回転支持具８の回転を伴う揺動基部であるので過剰負荷や、配線どうしの絡みが生じないようにできる。 As a result, the fixed support tools 3 and 4 support the plurality of crossover wires 5 and 6 while suppressing the bulkiness of the upper and lower sides in an array state so as to spread in the width direction of the vehicle bodies 1 and 2 rather than the vertical direction. Since the support position is the swing base part with the rotation of the rotation support 8 where the movement of the wirings 5 and 6 is small, it is possible to prevent excessive loads and entanglement between the wirings.
また、回転支持具８は、固定支持具３、４での支持配列から複数の渡り配線５、６を車体１の幅方向よりも上下方向、つまり回転支持具８の縦軸７の軸線方向に広がる配列状態にて支持して、渡り配線５、６が曲線走行時の車体１、２の連接端部１ａ、２ａ間の相対移動に追随するときの縦軸７まわりに屈伸しながら揺動する場合の負荷や配線どうしの絡み合いを軽減することができる。また、上下方向には広がるが既述のように許容される高さ域内に限って適用することができる。 In addition, the rotary support 8 is configured so that the plurality of transition wires 5 and 6 are arranged in the vertical direction with respect to the width direction of the vehicle body 1, that is, in the axial direction of the vertical axis 7 of the rotary support 8. Supporting in an expanded arrangement state, the crossover wirings 5 and 6 swing while bending and stretching around the vertical axis 7 when following the relative movement between the connecting end portions 1a and 2a of the vehicle bodies 1 and 2 during curve traveling. It is possible to reduce the entanglement between the load and the wiring. In addition, the present invention can be applied only within the height range that is allowed in the vertical direction but spread as described above.
回転支持具８を支持する支持基体３６は、上下の支持腕３３、３４をチャンネル材として、それらの背部の長手方向中央部間を角型の中空柱よりなる連結部材３５にて溶接接合により連結することで必要強度を確保している。特に下の支持腕３４をその溝開口部で片持ち支持部材３１である固定ブラケット１３に当てがいねじ止めすることで、材料力学的に有利なボックス構造をなして強固に設置できる。 The support base 36 that supports the rotary support 8 is connected by welding joint between the longitudinal center portions of the back portions of the upper and lower support arms 33 and 34 with a connecting member 35 made of a rectangular hollow column. This ensures the necessary strength. In particular, when the lower support arm 34 is screwed against the fixing bracket 13 which is the cantilever support member 31 at the groove opening, the box can be firmly installed with a box structure advantageous in terms of material mechanics.
これに併せ、縦軸７は、回転支持具８の挟持板８ａまたは８ｂの上辺および下辺に、取り付け座７ａを螺子４３でねじ止めし、上下の支持腕３４に下方から挿入して取り付け座４４ａを螺子４５でねじ止めした軸受４４に嵌め合わせることで、回転支持具８が回転できるように支持されるようにし、取り付け座７ａ、４４ａ間には平ワッシャ４６と無給油ワッシャ４７とを介在させてガタつきを防止し、オイルレスに構成している。 At the same time, the vertical axis 7 indicates that the mounting seat 7a is screwed to the upper and lower sides of the sandwiching plate 8a or 8b of the rotary support 8 with screws 43, and is inserted into the upper and lower support arms 34 from below to mount the mounting seat 44a. Is fitted to a bearing 44 screwed with a screw 45 so that the rotary support 8 can be rotated, and a flat washer 46 and an oilless washer 47 are interposed between the mounting seats 7a and 44a. This prevents oil from rattling and is oil-free.
なお、図示例の車体間配線構造のように低床鉄道車両の屋根上の配線に適用して好適であるが、上下方向に省スペースな配線にて曲線走行時の車体１、２の連接端部１ａ、２ａ間の相対移動に対応できることから、屋根上に限らず、非低床車両を含む床下配線に適用しても有効である。 It is suitable to be applied to the wiring on the roof of a low-floor railway vehicle like the inter-vehicle wiring structure in the illustrated example, but the connecting end of the vehicle bodies 1 and 2 when running in a curve with a space-saving wiring in the vertical direction Since it can respond to the relative movement between the parts 1a and 2a, it is effective not only on the roof but also when applied to underfloor wiring including non-low floor vehicles.
本発明は、鉄道車両の車体の端部間の車体間配線構造において、曲線走行時の車体の端部間の相対移動に追随するのに、上下方向に省スペース化するのに実用できる。 INDUSTRIAL APPLICABILITY The present invention can be practically used for space saving in the vertical direction to follow the relative movement between the end portions of the vehicle body during curve traveling in the inter-vehicle wiring structure between the end portions of the rail vehicle body.
