Description

  The present invention relates to a jumper device for communicating passages between passenger cars connected to each other by a coupler.

  The through-passage for the passengers to go back and forth between the passenger cars connected by the coupler is constituted by a holo (top) 11 and a crossover facility as illustrated in perspective views in FIGS. 5 (a) and 5 (b). . In general, the holo 11 has a structure in which a bellows-like surface material and a bone are combined. Conventionally, as a transitional facility, a sun plate (cross plate) configuration as shown in (a), a sun plate as shown in (b), A transition board configuration is generally used.

  The crossover equipment has a structure that can smoothly expand, contract, and bend in response to forward / backward / left / right / top / bottom displacement when the vehicle passes a steep slope or curved part. The transition board device has a structure in which the sun plates 1 and 1 are projected from the end portions of the vehicle, and are superposed on each other. On the other hand, the crossing equipment (crossing board device 10) of the sun board / cross board structure projects a short sun board 1 and 1 from the end of the vehicle, respectively, and can follow the displacement of the vehicle on the pantograph mechanism (link mechanism) ) With a tortoiseshell-shaped bridge plate 2 (see, for example, Patent Document 1).

  FIG. 3 is a cross-sectional view in the rail direction showing the structure of a bridge plate device having a sun plate / bridge plate configuration in a railway vehicle, and FIG. 4 is a view of the bridge plate device as viewed from the lower surface side of the vehicle.

  This transition board device 10 supports a sun board 1, 1 attached to a rail direction end part (flat girder part) of each vehicle, a transition board 2 that covers a gap between these sun boards 1, 1, and this transition board 2. It is composed mainly of two pantograph mechanisms 5 and 5. In addition, the code | symbol 12 in a figure is a connector provided in the front-back end of the advancing direction (rail direction) of a rail vehicle.

  The pantograph mechanism 5 includes thick plate-like long and short links 51 and 52, a pin 54 that is positioned in the center of the pantograph and rotatably supports the bridge plate 2, and a pin that connects the ends of the links 51 and 52. Are connected to connecting portions 53x, 53x of a pair of pantograph connecting members 53 attached to the vehicle side by pins 56, 56 located at the front and rear ends in the rail direction. .

When the vehicle is bent due to traveling on a curved track or the like, the links 51 and 52 of the pantograph mechanism 5 are rotated with respect to the pins 54, 55 and 56 joining the pantographs, respectively. Is deformed so that the plate 2 can follow the bending between the vehicles. The pantograph connecting member 53 is fastened to a fixing portion (fixing base 3) provided on the vehicle body side using detachable fixing pins 31 and 31. When the connection between the vehicles is released, the bridge plate 2 and each The pantograph mechanism 5 is configured to be removable.

  By the way, in recent years, in order to cope with the barrier-free in the railway vehicle, an attempt has been made to design the floor of the vehicle lower than the current level and make the step between the platform and the side of the passenger cabin smaller. The through-passage between them is also required to be flat and not cause a step for barrier-free and safety reasons.

  On the other hand, the railway vehicle connector placed under the through-passage needs to have the same height from the rail for all vehicle types in consideration of the combination at the time of rescue. The holo located at can not be lowered from its current position to avoid contact during travel. Therefore, if the height of the vehicle floor surface is lowered while the height of the coupler is kept constant, and the through-passage between the vehicles is to be made flat, the bridge plate device must be made thin.

  Specifically, in FIG. 3, even when trying to lower the height of the vehicle floor surface, there is concern about contact due to the vertical movement of the vehicle body during traveling, so the lower surface of the holo 11 and the uppermost surface of the coupler 12 During this period, it is difficult to approach (i.e., reduce the distance) from the current level. Therefore, in a vehicle designed to have a floor height lower than that of a conventional vehicle, the pantograph mechanism (link mechanism) that supports the bridge plate 2 is made thinner than the conventional product in order to keep the through passage flat. There is a need to configure.

  The present invention has been made to address the above-described problems, and an object of the present invention is to provide a railroad vehicle crossing board device that can achieve a reduction in thickness and weight while maintaining performance equivalent to that of a conventional product. It is said.

  Conventionally, a bridge plate device that constitutes a through-passage of a railway vehicle has been supported by a pantograph mechanism constituted by using a link made of a thick plate having sufficient strength to support the bridge plate. As a result of studying the strength of each link constituting the pantograph in order to reduce the thickness of the pantograph mechanism, the present inventors have achieved the same function as the conventional one even with a thinner link than the conventional product. I found that I can maintain it.

  However, as a result of repeated three-dimensional simulations and experiments during vehicle running in order to verify the validity of the structure of the railroad vehicle crossing board device using a thinner link than the conventional product, simply reducing the board thickness When an extreme displacement occurs between the vehicles, the thin pantograph mechanism may be twisted, and the connection end of each link may come into contact with the pantograph connecting member that supports the pantograph mechanism. I understood.

The present invention has been made on the basis of the above knowledge, and the invention according to claim 1 includes a sun plate that is disposed so as to protrude from the rail direction end of each railway vehicle so as to face each other. A crossing plate passed over the sun plate, two pantograph mechanisms arranged in the sleeper direction below the cross plate and rotatably supporting the cross plate, and a vehicle end under the sun plate And a pantograph connecting member spanned between the fixed parts, and the front and rear ends of each pantograph mechanism in the rail direction are connected to the pantograph of each vehicle. In the transition board device of a railway vehicle that supports the transition board so as to be able to follow relative displacement between the vehicles by connecting to the connection parts provided on the member, the pillow of the connection part of the pantograph connecting member The opposite sides, wherein the relief portion for preventing contact between the pantograph mechanism is formed.

  With the above configuration, this bridge plate device can avoid any contact between these links and the pantograph connecting member even when each link of the pantograph mechanism that supports the bridge plate is formed of a thin plate. Therefore, the crossing board device for a railway vehicle according to the present invention is configured so that a through-passage between the vehicles is flat while securing a gap in consideration of the movement of the vehicle even in a vehicle designed to have a floor height lower than that of a conventional vehicle. It becomes possible to do.

  In addition, the thin pantograph mechanism can reduce the weight of the entire transition board device, and also has an advantage that the transition board device can be easily detached and attached when the vehicle connection is separated and combined.

  As described above, according to the railroad vehicle crossing board device of the present invention, it is possible to realize a reduction in thickness and weight while maintaining the same function and safety as the conventional product.

  Further, the weight reduction makes it easy to remove and attach the jumper device when the vehicle is separated and combined.

Hereinafter, embodiments for carrying out the present invention will be described with reference to the drawings.
FIG. 1 is a cross-sectional view in the rail direction showing the structure of a railroad crossing board device according to an embodiment of the present invention, and FIG. 2 is a view of the crossing board device as seen from the lower surface side of the vehicle. In addition, the same code | symbol is attached | subjected to the structural member which has the same function as a prior art example.

  The crossover equipment in this embodiment is also a crossboard device having a sunplate / crossover plate configuration. Like the conventional example, the sunplates 1 and 1 attached to the ends in the rail direction (flat ends) of each vehicle, and the sunplate 1 , 1 and the two pantograph mechanisms 4, 4 that support the bridge plate 2.

  The pantograph mechanism 4 includes plate-like long and short links 41 and 42, a pin 44 that is positioned in the center of the pantograph and rotatably supports the crossing plate 2, and a pin that connects the end portions of the links 41 and 42. Are connected to a pair of pantograph connecting members 43 attached to the vehicle side by pins 46, 46 positioned at the front and rear ends in the rail direction.

  A feature of the railroad plate transition board device in the present embodiment is that each link 41, 42 used in the pantograph mechanism 4 is formed using a plate material thinner than the link (51, 52) employed in the conventional crossover board device. In addition, the pantograph connecting members 43 and 43 that support the pantograph mechanism 4 are provided with escape portions 43 a and 43 b that prevent contact with the pantograph mechanism 4.

  Further, the escape portions 43a and 43b of the pantograph connecting member 43 are located on both sides in the sleeper direction of the connection portion 43x to which the pantograph mechanism 4 is connected (the central side escape portion 43a and the fixed pin side escape portion 43b) with respect to the pantograph mechanism 4. Even if the phase shift in the sleeper direction between the vehicles is maximized, each end of the pantograph mechanism 4 in the sleeper direction (position of the pin 45) is formed. Is configured not to contact the pantograph connecting member 43.

  With the above configuration, the bridge plate device 10 in this embodiment can employ a link having a thinner shape than the conventional bridge plate device while maintaining the same function and safety as the conventional product. Further, the railroad vehicle crossing board device according to the present embodiment can realize a thin and light weight, and also ensure a gap between the holo 11 and the coupler 12 and a gap between the holo 11 and the pantograph mechanism 4. In this state, the through path between the vehicles can be configured to be flat, which is suitable for a vehicle designed to have a floor height lower than that of a conventional vehicle.

  In addition, the shape of the pantograph coupling member of the pantograph mechanism in the present invention is not limited to the shape example in the above embodiment. Further, the pantograph connecting member can be processed easily and without causing an increase in cost by using, for example, a laser cutting machine.
