DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vehicle control device mounted under the floor of a railway vehicle or the like, and more particularly, to an assembling work of electric and electronic equipment constituting the vehicle control device into a box frame and maintenance. The present invention relates to a vehicle control device suitable for improving work.

[0002]

2. Description of the Related Art FIG. 4 is a front view showing a device arrangement of a conventional vehicle controller integrated box. FIG. 5 is a side view of FIG. In the figure, reference numeral 1 denotes a box frame suspended from a chassis 2 of a train;
Is a high-voltage device unit housed in the box frame 1, and 4 is a built-in device unit such as a control device. 5 is an inspection cover on the bottom of the box frame, 6 is an inspection cover on the side of the box frame, 7 is an outgoing port for outfitting wiring for external input / output lines connected to the high-voltage equipment unit in the box, and 8 is an outlet for control circuit wiring.

As shown in FIG. 4, the conventional integrated box for a vehicle control device has a box frame configuration over the entire chassis of a train. In addition to the work of assembling and mounting from the inspection cover side, it is indispensable from the inspection opening on the bottom side provided near the center of the box frame into the inside of the box in terms of the structure of the integrated box frame. For this reason, the assembly is complicated and a large amount of time is spent on the assembly work.

In the above-mentioned conventional control box for a vehicle, when the built-in equipment unit is maintained and inspected, particularly when the equipment is disposed near the center of the box frame, the equipment box below the vehicle floor and the narrow space under the rail are narrow. , The inspection bottom cover provided on the bottom of the equipment box was removed to perform maintenance and inspection of the built-in equipment unit. Japanese Patent Publication No. 5-199601 discloses a related apparatus of this type.

[0005]

According to the above-mentioned prior art, incorporation and mounting of a built-in device unit or the like of a storage device into an integral box frame is performed by not only from the right and left side inspection cover sides of the integral box frame but also from the center of the bottom of the integral box frame. Since the built-in device unit is also inserted into the box through the inspection port provided in the section and mounted, when mounting the storage device, the work of assembling into the box from a narrow space such as the inspection port on the bottom portion.

[0006] As a result, the assembling workability is poor, and a great deal of time has been spent on the work. In addition, during maintenance and inspection of storage equipment in the apparatus, since the integral box frame is entirely suspended over the floor of the vehicle, the built-in equipment unit particularly disposed near the central portion of the integral box frame. In the case of, there is a problem that the work efficiency is poor because maintenance and inspection are performed after removing the inspection cover provided on the bottom surface of the integrated box frame from a narrow space between the integrated box for the vehicle control device and the lower surface of the rail. .

SUMMARY OF THE INVENTION An object of the present invention is to solve the above-mentioned problems, and it is an object of the present invention to eliminate the bottom inspection cover system and to improve the assembling workability and the maintenance and inspection performance. It is to provide a control device.

[0008]

In order to achieve the above-mentioned object, in a vehicle control device having an integrated box structure mounted under a floor of a railway vehicle or the like, the above-described box frame structure is formed by connecting two longitudinal boxes of the same shape in parallel. In addition, a space where the side covers of the long box can be attached and detached,
That is, a work space required for an assembly inspection work or the like is provided with a space, and the long boxes are attached to a suspension frame duct provided on the upper surface of the box to form an integral box frame structure.
In addition, in order to electrically connect the long boxes, a connecting wire is inserted into a suspension frame duct provided on the upper surface of the box to enable electrical connection between the devices. In other words, the integrated box structure of the vehicle control device has two long boxes of the same shape or two similar long boxes arranged in parallel and combined on both sides, and the interval between the long boxes is long. Secure an appropriate space for opening and closing the side cover of the hand box. Thus, a one-box configuration is adopted. In this duct portion, a lead-in port for outfitting wiring from the vehicle body side to the vehicle control device, and further, a crossover wiring for electrical connection of the built-in equipment unit and the like of the longitudinal boxes are performed.

[0009] With this, the installation of the built-in equipment unit of the storage device into the box frame can be performed in the same procedure as the longitudinal box, so that the assembling workability is improved and the bottom inspection cover system unique to the integral box frame is provided. Is eliminated, maintenance and inspection work after removing the inspection cover from the narrow space between the bottom surface of the apparatus and the lower surface of the rail on the lower side is eliminated, and efficiency can be improved.
