Description

[Detailed description of the device]

[0001]

[Industrial application]

 The present invention relates to a device for controlling an abnormal deviation of a vehicle connecting hood.

[0002]

[Prior Art]

 Conventionally, in railway vehicles, the connecting hoods that are connected between the vehicle bodies have their both ends connected to the opposite end faces of the vehicle body, and the connecting hoods are also displaced by following the displacement of the vehicle body. However, even if the bias is abnormal, the bias state is generally not regulated.

[0003]

[Problems to be solved by the device]

 When a vehicle passes over an S-curve with a large body deviation such as a non-business track, as shown in FIG. 6, both ends of the connecting hood (2) connecting the vehicle bodies (1) and (1) are opposite to each other on the left side. Largely biased to the right. In the case of such a deviation, in the case where there is no means for restricting the abnormal deviation of the connecting hood as in the conventional case, the connecting hood (2) is shown together with the inclination of the intermediate frame (3) provided in the central portion thereof. As described above, there is a problem in that the portion (2a) that is biased toward the body end face side slides in contact with the body end face, and the hood cloth of the portion (2a) is damaged, shortening the life of the connecting hood.

Further, as shown in FIG. 6, in the case where the intermediate transition plate (4) is also inclined similarly to the intermediate frame (3), the corner portion (4a) of the transition plate (4a) at the time of the deviation as described above. There is also a problem that) contacts and slides on the inner surface of the connecting hood (2) and damages the hood cloth.

Therefore, the present invention regulates the intermediate frame of the connecting hood so as to move parallel to the car body end face without tilting as described above even in the case of the large deviation as described above. The purpose is to solve the problem of damage to the hood cloth. The device disclosed in Japanese Utility Model Publication No. 50-43848 for controlling the abnormal deviation of the cross plate is known, but this device is not a measure for preventing damage to the hood cloth, but a device for protecting a passage for passengers. Moreover, in this conventional technique, the vertically extending sliding grooves provided on the rising plates on both sides of the transition plate and the central node pin of the pantograph-shaped link mechanism are always engaged, so that the problem of wear in a short period of time is encountered. There is a point. There is also a problem that the passage width cannot be widened because the link mechanism is placed between the hood and the rising plate. The present invention also aims to solve these problems.

[0006]

[Means for Solving the Problems]

 In order to solve the above problems, the present invention provides an intermediate frame (7) fixed to the open side ends (6b) (6b) of the connecting hoods (6) (6), and the intermediate frame (7). A movable bridge plate (12) or a movable ceiling panel (17) that is integrally connected to each other in the front-rear and left-right directions without mutual displacement, and the movable bridge plate (12) on the left and right sides of the end faces of both vehicle bodies (1) (1). ) Or the front and rear end faces of the left and right parts of the movable ceiling panel (17) with a space therebetween, and contact with the front and rear end faces when the movable bridge plate (12) or the movable ceiling panel (17) is abnormally biased. In addition, it is characterized in that it is provided with restricting members (15) and (18) for restricting further deviation.

[0007]

[Action]

 As shown in Fig. 2, when the vehicle passes over the S curve, both ends of the connecting hood that connects the vehicle bodies (1) and (1) are greatly and abnormally biased to the opposite left and right sides. A central cross plate (12) is biased as shown. At this time, the end surface of the transition plate (12) passing through the inner surface of the metal frame (5) while being drawn toward the vehicle body side metal frame (5) is in sliding contact with a guide roller (15) which is a regulating member. However, the planar deflection angle of the transition plate (12) is regulated so as not to become larger than a certain value.

In addition, the ceiling panel is regulated similarly. Therefore, the swing angle of the intermediate frame of the connecting hood connected to the connecting plate or the ceiling panel is also restricted, and the connecting hood connected to the intermediate frame is also restricted from being pulled toward the vehicle body. Therefore, the portion of the hood cloth that is about to be pulled toward the vehicle body is prevented from abutting against the car body end face, and it is possible to prevent the hood cloth from contacting and sliding with the car body end face and being damaged.

[0009]

【Example】

 Next, an embodiment of the present invention shown in FIGS. 1 to 5 will be described. Reference numerals 1 and 1 denote connected vehicle bodies, and vehicle body-side top metal frames 5 and 5 are fixed to respective opposing end faces through fixed frames 1a and 1a. As is well known, the vehicle body side top metal frames 5 and 5 are formed so as to have a front shape of a square shape.

The connecting hood is divided into two parts 6 and 6 in the vehicle direction, each vehicle body side end 6a is fixed to the vehicle body side hood metal frame 5, and the release side metal hood frame 7 is fixed to the release side end 6b. ing. Then, the open side top metal frames 7, 7 of the both connecting tops 6, 6 are brought into contact with each other and connected to each other by fastening members or the like to form an intermediate frame, and as shown in FIG. The connecting portion between 1 is covered with both connecting hoods 6, 6.

The opening side top metal frames 7, 7 are formed in a b-shape from the front. A balance spring 8 is installed between the bottom frame portion of the metal frames 7, 7 and the top metal frame 5 on the vehicle body side so as to position the metal frames 7, 7 at the center between the vehicle bodies 1, 1. Further, brackets 9 for supporting the transition plates are fixed by bolts 10 on the left and right upper surfaces of the bottom frame portions of the metal frames 7, 7.

A bridge plate that connects the vehicle bodies 1 and 1 connects two vehicle body side bridge plates 11 and 11 that are provided on the end faces of the vehicle bodies 1 and 1 so as to maintain a horizontal state, and connects these intermediate parts to each other. It is composed of a single central connecting plate 12. A bracket 13 is fixedly attached to the lower surface of the central connecting plate 12 at a portion corresponding to the bracket 9 provided on the release side top metal frame 7, and both brackets 9 and 13 are rotated by a rotary shaft 14. A central crossing plate 12 is provided so that it can be connected as much as possible, and its front and rear ends can be vertically moved by the rotating shaft 14.

In addition, since the left and right parts of the center crossing plate 12 are connected to the release side metal frame 7 as described above, both of them are always biased with respect to the front-rear direction and the left-right direction. It moves integrally while maintaining the set mutual positional relationship.

Reference numeral 15 is a guide roller which is a regulating member provided on the vehicle body side metal frame 5, and is adapted to rotate about the vertical shaft 15a. The guide roller 15 is located on a locus in which the central crossing plate 12 horizontally moves in the left-right direction and is set to project from the vehicle body side end 6a of the connecting hood 6 toward the hood center. A total of four guide rollers 15 are provided on the left and right sides of the vehicle body side top metal frames 5, 5.

The front and rear end faces of the left and right portions of the central connecting plate 12 are formed into tapered surfaces 12 a so that they easily engage with the guide rollers 15 when the connecting plate 12 moves. A ceiling panel in each of the divided connecting hoods 6, 6 has a ceiling panel divided into a vehicle body side ceiling panel 16 and a hood side ceiling panel 17, and the base end of the hood side ceiling panel 17 is It is fixed to the lower surface of the upper frame of the release side top metal frame 7, the base end of the vehicle body side ceiling panel 16 is supported on the end face side of the vehicle body 1 so as to be vertically movable, and the tip end portion thereof is the top ceiling panel 17. It is slidably supported on the top.

The hood side ceiling panel 17 is formed in a plane shape so as to have the same shape as the central connecting plate 12 when the panels 17 and 17 provided on the coupling hoods 6 and 6 are coupled to each other. ing. A guide roller 18 similar to the guide roller 15 is provided on the vehicle body-side top metal frame 5 so as to engage with the top-side ceiling panel 17. This engagement relationship is similar to the relationship between the central crossing plate 12 and the guide roller 15.

Reference numeral 19 is a fixed wall surface panel fixed to the release side metal frame 7. Reference numeral 20 denotes a movable wall surface panel which is provided on the end surface side of the vehicle body 1 so as to be able to rotate in a plane, and its tip is slidably in contact with the inner surface of the fixed wall surface panel 19.

Although the regulating member is the guide roller in the above embodiment, it may be a simple protrusion.

[0019]

[Effect of the device]

 As described above, according to the present invention, the planar deflection angle of the bridge plate or the ceiling panel is regulated so that it does not become larger than a certain value during abnormal deviation, and the middle frame of the coupled hood connected to this is also regulated. Therefore, it is possible to prevent the front and rear end faces of the connecting hood from coming into contact with the body gable face. Therefore, unlike the conventional case, the hood cloth does not come into contact with and slide on the end surface of the vehicle body and is not damaged, and the durability of the connected hood can be improved.

Further, since the deflection angle of the crossover plate or the ceiling panel is regulated as described above, it is possible to prevent the hood cloth from being damaged by coming into contact with the hood cloth when the deviation is abnormal. Further, since the front and rear end surfaces of the movable connecting plate and the movable ceiling panel do not come into contact with the regulating member when the vehicle passes along a straight line, wear resistance of the abutting portion is good, and in addition, a complicated pantograph-like link mechanism is used. Since it is not provided inside the hood, the passage width can be increased.

Further, in the case where the connecting hood has the wall panel divided in the front-rear direction, it is possible to prevent the both wall panels from being detached when the wall is abnormally biased.
