Description

本発明は、鉄道車両用の台車に関し、特に、鉄道車両の脱線復旧の際に、車体吊り上げ時に車体と台車を一括して吊上げるための台車分離防止装置に関する。   The present invention relates to a bogie for a railway vehicle, and more particularly, to a bogie separation prevention device for lifting a car body and a bogie collectively when the car body is lifted at the time of derailment recovery of the railway vehicle.

鉄道車両用の車体分離防止装置は、脱線等の異常事態を復旧させる際、或いは車両の大がかりな保守点検の際に、車両をクレーン等の機器で持ち上げる場合があるが、このときに車体と台車が分離すると、車体の取り扱いが困難になり好ましくないことがある。そこで、車体と台車を一括して吊上げることを可能にするための装置が求められている。   A vehicle body separation prevention device for a railway vehicle sometimes lifts the vehicle with a device such as a crane when recovering from an abnormal situation such as derailment or during a large-scale maintenance inspection of the vehicle. If separated, it may be difficult to handle the vehicle body, which may be undesirable. Therefore, there is a need for a device that enables the vehicle body and the carriage to be lifted together.

一方、鉄道車両の保守点検の一貫として定期的な検査を実施するときには、車体と台車の取り外し作業を行わねばならない。こうした場合の車体と台車の分離防止装置を備えた場合には、当該台車分離防止装置の機能が働かないように解除する必要がある。即ち、まず、上記車体分離防止装置を取り外し、その後、牽引装置の個々の部品を取り外す必要があった。   On the other hand, when carrying out periodic inspections as part of the maintenance and inspection of railway vehicles, it is necessary to remove the car body and the carriage. In such a case, when the apparatus for preventing separation between the vehicle body and the carriage is provided, it is necessary to release the function so that the function of the carriage separation prevention apparatus does not work. That is, it is necessary to first remove the vehicle body separation prevention device and then remove individual components of the traction device.

車体と台車枠を一本の牽引リンクで連結するボルスタレス台車の牽引装置について、車体側の牽引リンクとの対向位置に中心ピンを垂下状に取り付け、牽引リンクには、その軸方向に異常上昇止めを、軸と直交する方向の両側には結合部を夫々水平状に取り付け、中心ピンの結合部と対向する部分に、結合部と嵌り合う嵌合凹部を形成するものが提案されている（特許文献１）。台車側のみに牽引リンクを取り付けた際に、牽引リンクと異常上昇止めと結合部の自重で、牽引リンクの車体への取り付け側が降下した状態でも、嵌合凹部と結合部が嵌合可能に、中心ピンの長さと嵌合凹部の奥行きを決定しているので、台入れ・台抜き作業を、ピットがない場合でも、容易に行うことを図っている。   About the bolsterless bogie traction device that connects the vehicle body and the bogie frame with a single traction link, a central pin is attached in a hanging shape at a position facing the traction link on the vehicle body side, and the traction link is prevented from rising abnormally in its axial direction Have been proposed in which coupling portions are attached horizontally on both sides in a direction perpendicular to the axis, and a fitting recess is formed in the portion facing the coupling portion of the center pin to fit the coupling portion (patent) Reference 1). When the traction link is attached only to the trolley side, even if the attachment side of the traction link to the vehicle body is lowered due to the weight of the traction link, the abnormal rise stopper and the coupling part, the fitting recess and coupling part can be fitted, Since the length of the center pin and the depth of the fitting recess are determined, it is possible to easily carry out the placing and removing operations even when there is no pit.

このような台車分離防止構造によれば、台車分離防止装置を外せば車体と台車の取り外し作業が可能になるが、部品点数が多く、作業が煩雑であり、作業時間が長くなるという問題がある。
特開２００５−１３８６０４号公報 According to such a cart separation preventing structure, the body and the cart can be removed by removing the cart separation preventing device, but there are problems that the number of parts is large, the work is complicated, and the working time becomes long. .

本発明による鉄道車両用の台車分離防止装置の実施例を、図１及び図２を参照して説明する。図１に示す鉄道車両用の台車分離防止装置の実施例においては、車体１０は台車１１の上に配置された空気ばね１６によりその荷重を支持されている。車体１０と台車１１は、図２に示すように、牽引（制動）方向については、一本リンク１３で連結して、牽引力を（制動力）伝える構成とされている。即ち、台車１１からは、一本リンク１３が、一端部において、車両横方向に軸線を有するピンの周りにゴム等の弾性部材を介した弾性連結構造１８で支持されている。一本リンク１３は、車体１０の前後方向に延びており、先端部側でも、同様のピン−弾性部材からなる弾性連結構造１９で、車体１０側の構造である中心ピン１７に連結されている。弾性連結構造１８，１９は、中心軸となるピン２０と、ピン２０の周囲を取り巻く状態に置かれたゴムリング２１と、ゴムリング２１の外側を覆い一本リンク１３に支持される鉄製のシェル２２とから成っている。 An embodiment of a truck separation preventing apparatus for a railway vehicle according to the present invention will be described with reference to FIGS. 1 and 2. In the embodiment of the bogie separation prevention device for a railway vehicle shown in FIG. 1, the vehicle body 10 is supported by an air spring 16 disposed on the bogie 11. As shown in FIG. 2, the vehicle body 10 and the carriage 11 are connected by a single link 13 in the traction (braking) direction and transmit the traction force (braking force). That is, the single link 13 is supported from the carriage 11 at one end by an elastic connection structure 18 through an elastic member such as rubber around a pin having an axis in the vehicle lateral direction. The single link 13 extends in the front-rear direction of the vehicle body 10, and is also connected to the center pin 17, which is a structure on the vehicle body 10 side, by an elastic connection structure 19 made of a similar pin-elastic member on the tip side. . The elastic connection structures 18 and 19 include a pin 20 as a central axis, a rubber ring 21 placed around the pin 20, and an iron shell that covers the outside of the rubber ring 21 and is supported by a single link 13. It consists of 22 and.

弾性連結構造１９のピン２０は一本リンク１３の幅よりも軸方向両側に延びている。ピン２０の延長した両端部２３，２３を貫通させた取付け用のボルト１５，１５は、中心ピン１７の二股端部２４，２４にねじ込まれる。ボルト１５の頭部でピン２０の延長した両端部２３を中心ピン１７の二股端部２４との間に挟み込むことによって、一本リンク１３は中心ピン１７に連結される。   The pins 20 of the elastic connection structure 19 extend on both sides in the axial direction rather than the width of the single link 13. The mounting bolts 15, 15 penetrating the extended ends 23, 23 of the pin 20 are screwed into the bifurcated ends 24, 24 of the center pin 17. The single link 13 is connected to the center pin 17 by sandwiching the extended end portions 23 of the pin 20 with the bifurcated end portion 24 of the center pin 17 at the head of the bolt 15.

台車分離防止装置１４は、ボルト１５，１５を使用して一本リンク１３を中心ピン１７側に取り付けている。即ち、分離防止装置１４は枕木方向に腕部１４ａ，１４ａを有しており、腕部１４ａ，１４ａ間の本体部１４ｂは一本リンク１３を下側に迂回する形状に構成されている。中心ピン１７の二股端部２４を貫通したボルト１５，１５の先端のねじ部分が本体部１４ｂにねじ込まれることによって、台車分離防止装置１４は中心ピン１７に取り付けられている。   The cart separation preventing device 14 uses bolts 15 and 15 to attach the single link 13 to the center pin 17 side. That is, the separation preventing device 14 has arm portions 14a and 14a in the direction of the sleepers, and the main body portion 14b between the arm portions 14a and 14a is configured to bypass the single link 13 downward. The bogie separation preventing device 14 is attached to the center pin 17 by screwing the screw portions at the tips of the bolts 15, 15 passing through the bifurcated end portion 24 of the center pin 17 into the main body portion 14 b.

上記のように取り付けられた台車分離防止装置１４によれば、車体１０をクレーン等の重機器で吊り上げた時には、台車分離防止装置１４が中心ピン１７と一緒に上昇するが、腕部１４ａ，１４ａの上面１４ｃが台車枠１２の下面１２ａに当接して台車枠１２をすくい上げて車体１０と台車１１とを一括して吊り上げることができる。これにより、車体１０の吊り上げ時に、車体１０と台車１１とが分離しない構性となっている。この時、台車１１の質量のアンバランスを考慮して、腕部１４ａ，１４ａがレール方向の台車１１の中央部辺りに当接することで、バランスを崩すことなく台車１１をすくい上げる構成にすることが好ましい。 According to the cart separation preventing device 14 attached as described above, when the vehicle body 10 is lifted by heavy equipment such as a crane, the cart separation preventing device 14 rises together with the center pin 17, but the arm portions 14a, 14a. of the upper surface 14c is Ru can be lifted at once and the vehicle body 10 and the carriage 11 by scooping the bogie frame 12 abuts against the lower surface 12a of the carriage frame 12. Thereby, when the vehicle body 10 is lifted, the vehicle body 10 and the carriage 11 are not separated. At this time, in consideration of an unbalance of the mass of the carriage 11, the arm portions 14 a, 14 a are brought into contact with the central portion of the carriage 11 in the rail direction so that the carriage 11 is scooped up without breaking the balance. preferable.

一方、保守点検で車体１０と台車１１を分離する必要があるときは、通常の車体１０と台車１１を分離する時の作業、即ち、中心ピン１７と一本リンク１３との結合を解除するのと同様に、ボルト１５，１５を取り外す作業のみによって、台車分離防止装置１４をも同時に中心ピン１７から取り外すことができる。この結果、台車分離防止装置１４を取り外すために必要な部品もボルト１５，１５のままであり、部品点数が増加しない。また、台車分離防止装置１４の取外し・取付け作業の時間の短縮化が実現できる。   On the other hand, when it is necessary to separate the vehicle body 10 and the carriage 11 in the maintenance inspection, the work for separating the normal vehicle body 10 and the carriage 11, that is, the connection between the center pin 17 and the single link 13 is released. Similarly, the cart separation preventing device 14 can be removed from the center pin 17 at the same time only by removing the bolts 15 and 15. As a result, the parts necessary for removing the carriage separation preventing device 14 remain the bolts 15 and 15, and the number of parts does not increase. Further, it is possible to reduce the time for removing and attaching the carriage separation preventing device 14.
