Description

Description: [Industrial field of use] The present invention relates to a railroad vehicle cleaning apparatus for cleaning the side surface of a vehicle body of a railroad vehicle.

[Prior Art] A cleaning device for cleaning the side surface of a railroad vehicle body is generally installed on both sides of the track of the vehicle, and a rotating brush is pressed against the side surface of the vehicle traveling at a low speed to achieve a predetermined sliding contact pressure. To wash the vehicle.

Conventionally, the rotating brush provided in this cleaning device is formed by a long cylindrical vertical rotating brush supported by a vertical rotating shaft, and the rotating brush is slidably contacted from the upper end to the lower end of the side surface of the vehicle. What to wash is known.

There is also known a cleaning device or the like that performs cleaning by combining a short cylindrical rotating brush and a truncated cone rotating brush according to the shape of the side surface of the vehicle.

[Problems to be Solved by the Invention] However, in the above-described conventional cleaning device including a rotary brush, in the case of the former long cylindrical rotary brush,
When cleaning the side surface of the vehicle, the sliding contact surface of the brush is uniformly pressed from the upper end to the lower end of the vehicle side surface. Therefore, the sliding surface of the rotating brush does not fully reach the window surface and window frame that are formed by recessing on the side surface of the vehicle, and the sliding contact surface of the rotating brush slightly touches the center of the window surface. There is a problem that the rotating brush does not reach the edge window frame and becomes a dead space, which makes cleaning difficult.

Further, in the case of the latter rotary brush described above, it is composed of a plurality of rotary brushes that match the shape of the vehicle side surface, such as a window rotary brush that can slidably contact the concave window surface of the vehicle side surface. In some cases, the rotating brush cannot be sufficiently slidably contacted with the window surface and the window frame without any clearance, and the window frame may not be cleaned like the long rotating brush described above. Even if it is possible, there is a problem in that both corners of the lower edge window frame, which is particularly dirty, become dead spaces in the shape of the rotating brush and in the cleaning direction, and cleaning cannot be performed.

Therefore, in order to solve the above-mentioned problems, the present invention can completely remove stains on the window frame of the window surface formed by recessing the side surface of the railway vehicle, and also cleans the side surface of the rail vehicle. It is an object of the present invention to provide a cleaning device for a rail vehicle.

The plurality of rotating brushes 19, 31, 33 other than the window frame rotating brushes 44, 49 individually clean the upper portion, the lower portion, and the shoulder portion of the vehicle side surface 6a.

In addition, in order to effectively perform the cleaning with the rotating brush,
It is necessary that the bristle tip of the outer peripheral brush surface touch the surface to be cleaned, but if the rotation axis of the rotating brush for the window frame is vertical, the bristle tip should rotate parallel to the lower edge of the window. Therefore, the dirt on the lower edge cannot be effectively cleaned. Further, when the outer peripheral brush surface of the rotating brush for the window frame is slid upward from the lower edge of the window portion in the opposite direction to the case of the present invention, the tip of the brush is the outer surface of the vehicle. Cannot be effectively washed because it splashes from the window surface 6s and does not hit the lower edge of the window. Furthermore, the rotating directions of the two window frame rotating brushes are the same, or
When the axes of rotation are parallel, when the vehicle is moved in one direction, only one of the two corners of the lower edge of the window is effectively washed, and as in the present invention described above, The two corners of the window are not effectively cleaned when moving.
