Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cleaning device for a railroad vehicle that runs and stops on a railroad track.

[0002]

2. Description of the Related Art In a vehicle cleaning device such as a railway vehicle, it is difficult to use a gate-shaped frame like a vehicle cleaning device because an overhead line exists on the track, and therefore the cleaning device itself is used. The so-called self-propelled cleaning device for running cannot be practically adopted because of its strength. Therefore, a fixed type cleaning device is generally used in which the cleaning device itself is fixed and the vehicle is cleaned while moving.

[0003]

However, in the case of such a fixed type cleaning device, there is a drawback that it is difficult to clean the front surface of the vehicle. That is, in the case of an automobile or the like, the rotating brush is hung down from the upper portion of the gate-shaped frame to wash the front portion of the automobile. As described above, when the gate-shaped frame cannot be adopted, the front portion of the vehicle is washed. There was a problem that it was difficult to attach the brush for. Moreover, at present, no structure of a brush has been proposed so far that the front portion can be washed while moving on the vehicle side even if the brush can be attached. For this reason, hand-washing by hand has been the mainstream of the front of railway vehicles.
Improvement of this point was desired. The present invention has been made in order to meet such a demand, and an object of the present invention is to provide a cleaning device capable of cleaning the front surface of a railroad vehicle such as a railroad vehicle.

[0004]

In order to achieve the above-mentioned object, the present invention is a cleaning device for a railroad vehicle that runs and stops on a track having an overhead wire provided above, and is installed upright on the side portion of the track. A supporting body, a moving body provided on the supporting body so as to be movable along the track, and a washing body for vehicle cleaning provided on the moving body so as to be able to move up and down and move back and forth on the track. It is characterized by having.

[0005]

With respect to the railcar that stops at a predetermined position on the track, the cleaning body projects in a track shape, and the cleaning body moves on the support body and the cleaning body moves up and down to move the cleaning body to the railway. Cleaning is performed by moving and abutting against the portion to be washed such as the front surface and the head of the vehicle.
