[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a railroad vehicle extra-highway crossing device.

[0002]

2. Description of the Related Art In a railway vehicle, a cable for distributing the electricity obtained by a final train on the roof of the vehicle to each vehicle is arranged along the longitudinal direction on the roof of the vehicle, and the distance between the vehicles is very high. It is connected by a migrating device. This extra-highway crossing device
A cable connector, that is, a conductive insulator is installed on the upper surface of the roof at the end of the vehicle, and a cable is connected between two vehicles, that is, between the two conductive insulators. The other end of the conductive insulator is connected to a cable installed on the roof along the longitudinal direction of the vehicle. The conductive insulator is installed on the roof so as to project vertically or horizontally from the vehicle.

[0003]

The conventional extra-high-passage device generates noise because the conductive insulator and the cable are projected on the roof. In particular, noise is significantly generated in a vehicle traveling at high speed.

Also, since the extra-high-passing device of the prior art is mounted on the roof, when connecting / disconnecting the vehicle, it goes up onto the roof and the cable is mounted / removed, thereby eliminating a dangerous work. I couldn't. It is an object of the present invention to provide complete abolition of dangerous work such as rooftop work since the crossover cable can be attached and detached from the inside of the vehicle.

A first object of the present invention is to provide an extra-high crossover device for reducing the protrusion from the roof.

A second object of the present invention is to enable connection / disconnection of the transition cable of the extra-high transition device from the inside of the vehicle.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to FIGS. Reference numeral 10 is a vehicle that constitutes a rolling stock. A high-voltage cable 15 is installed in the center of the upper surface of the roof 11 of the vehicle 10 along the longitudinal direction of the vehicle 10. Reference numeral 19 is a connecting hood.

Reference numeral 30 denotes a cable connector of the extra-high-passage device, in which the outer periphery of a conductive member (not shown) is covered with an insulator such as an insulator so that the insulator can be fixed to the vehicle. Functionally, it is similar to a conductive insulator called a cable head, and is hereinafter referred to as a conductive insulator. Conductive insulator 30
Has a connection portion with the cable 15 at one end, and has a connection cable 35 of the extra-high-passage device connected to the other end. Cables 15 and 35 are detachably attached to the respective connecting portions by bolts and nuts (not shown) as is well known. The crossover cable 35 is flexible and has two conductive insulators 20, 20.
The space between them is curved horizontally. This curvature allows for changes in the spacing between the two vehicles, as well as bends and deviations.

The connecting height of the cable 15 on one end side of the conductive insulator 30 and the connecting height of the transition cable 35 on the other end side are different. The latter is lower. Therefore, the outer shape of the conductive insulator 30 is formed in a so-called Z shape as shown in the drawing. The conductive member inside the conductive insulator 30 is also Z-shaped. The structure of the conductive insulator 30 described above is substantially the same as the known structure in which the connecting ends at both ends are provided at the same height except that the outer shape and the conductive member are Z-shaped. Conductor insulator 3
Since the zero conductive member is provided in the Z shape, the cable 15,
The connecting direction with the crossover cable 35 is horizontal. Therefore, the connecting surface is a vertical surface. Conductor insulator 3
The reason why the zero conductive member is provided in a Z shape is to prevent the generation of noise by reducing the length of the extra-high-passage device projecting above the roof 11 as much as possible. A mounting seat 31 is provided on the lower surface of the central portion in the longitudinal direction of the conductive insulator, and the bolt 3 is attached to the horizontal surface 14 of the concave portion 13 at the central portion of the end of the roof 11.
It is fixed at 2. The plate forming the recess 13 is made of the same material as the roof 11 and is fixed to the roof 11 by welding.

Reference numeral 40 denotes a cover for covering the upper surface of the recess 13, that is, the conductive insulator 30 and a part of the crossover cable 35.
It is fixed by bolts 41 to the upper surface of the roof 11 and the vertical surface of the end of the vehicle. The bolt 31 arranged on the upper surface of the roof 11 is an embedded type. A cross section along the longitudinal direction of the vehicle is L-shaped, and a hole 40a through which the crossover cable 35 passes is provided on a vertical surface. The size of the hole 40a is such that a fitting connected to the conductive insulator 30 can pass through. The upper surface of the cover 40 projects upward at the upper surface of the conductive insulator 30. It smoothly descends toward both ends in the longitudinal direction.

A closing plate 22 is attached to the lower surface of the connecting portion between the conductive insulator 30 and the crossover cable 35. Block 2
The size of 2 is such that the conductive insulator 30 and the transition device 35 can be attached / detached from inside the vehicle, that is, below the connecting portion. The closing plate 22 is detachably fixed to the lower surface of the recess 13 from below by a bolt 23 via a waterproof and airtight packing (not shown). Further, below the closing plate 22 is a living space or passage 25. Reference numerals 26 and 27 denote a ceiling and walls that form the passage 20. The inspection lid 28 on the lower surface of the closing plate 22 is configured to be easily attached and detached from below. The means for attaching / detaching the ceiling plate 28 is the same as the structure of the well-known inspection lid for the ceiling surface.

According to such a configuration, the amount of the extra-high-passage device protruding above the roof 11 is reduced. In addition, since the cable connector (insulator for conduction) 30 is Z-shaped, the amount of protrusion is smaller. Moreover, since the extra-high-passage device is covered with the cover 30, the air flows smoothly. This can reduce the generation of noise.

Since the conductive insulator 30 is of Z type, the length of the conductive insulator itself can be shortened and the influence on the equipment arranged at the end of the roof can be minimized.

When the connected vehicles are split, the inspection lid 28 is removed, the closing plate 22 is removed, and the connecting portion between the conductive insulator 30 and the crossover cable 35 is removed from this opening. Then, the end of the crossover cable 35 is put out from the hole 40a of the cover 40. This work can be easily performed by going up to the work table placed in the passage 20. In the past, the disconnection of the connection was performed on the roof 11, which was dangerous, but according to the present embodiment, this danger can be prevented. Further, since the conductive insulator 30 is Z-shaped, the connecting portion with the crossover cable 35 is located further downward, so that the disconnecting work can be performed more easily and safely. The connecting work can also be performed from the passage 20 side.

The conductive insulator 30 and the crossover cable 35.
If the connection surface with is not horizontal as in the above embodiment but is horizontal, the separating operation can be performed more easily.

In the above-described embodiment, the extra-high-rise crossover device connects the vehicles, but a crossover cable (fixed to the side surface of the end of the vehicle) for connecting the roof of the own vehicle to the traveling motor and the like at the bottom is provided. It can also be used when connecting.

[0021]

According to the present invention, since the conductive insulator is Z-shaped and arranged in the concave portion of the roof of the vehicle end, it is possible to reduce the amount of protrusion which becomes a noise source during traveling, It is possible to reduce aerodynamic noise during high-speed traveling.

Further, since the work for connecting / disconnecting the crossover cable 3 which was the work on the roof can be carried out from the inside of the vehicle, it is not necessary to go up on the roof and dangerous work can be abolished. It is a thing.
