A balancer 44 is provided between the arms 36 and 37.

Further, although not shown, the cleaning device 1 is provided with a detecting portion in the vicinity of the cleaning device 1. The detection unit is composed of an optical system sensor or the like, and detects the outer shape of the vehicle T moving on the track L at a low speed. Then, after detecting the shape of the vehicle T, this detection signal is sent to the cleaning device 1, and the inclination angle of the rotary brush 40 by each drive unit of the cleaning device 1 and the height position,
The push stopper position is set and controlled.

Next, the operation of the cleaning device 1 for the side skirt portion S of the vehicle T constructed as described above will be described with reference to the drawings. Each operating portion of the cleaning device 1 is in an initial state as shown in FIG. 6, that is, the elevating frame 9 is located at the lowermost portion, and the support frame 24 is in a vertical state.
1 is not rotated, the segment gear 32 is in contact with the restriction piece 35 as shown in FIG. 5, and the rotating brush 40 is in a state of being stored in the left half portion of the base 2 in FIG.

First, the vehicle T moves on the track L at a low speed to the cleaning device 1 as shown in FIG. 3 (arrow A). As the vehicle T approaches, the detection unit detects the outer shape of the vehicle T and sends the result to the cleaning device 1. Then, as shown in FIG. 8, the tilt angle adjusting unit 17 operates based on this detection signal to extend the working shaft 18, rotate the support frame 24 about the tilt shaft 25, and move the support frame 24. The base 2 is tilted in the elevation direction. That is, the tilt angle adjusting unit 17 tilts the rotary shaft 41 of the rotary brush 40 via the support frame 24 and the turning shaft 31. This inclination angle is between the lifting frame 9 and the support frame 24,
By comparing with the output signal of the encoder provided at the shaft end of the tilt shaft 25, the set tilt angle is reliably maintained. At the same time, the lift drive unit 11 operates to move the lift frame 9 upward along the guide rail 4. This upward movement can be smoothly moved because the balance weight 13 connected by the wire 12 is disposed on the back surface 3a side of the back plate 3.

When the vehicle T enters between the cleaning devices 1, the rotary brush 40 starts to rotate, the pressing drive unit 26 operates to rotate the turning shaft 31, and the rotary brush 40 is moved as shown in FIG.
As shown in FIG. 3, the cleaning is performed by projecting from the base 2 side to the track L side and pressing the rotating brush 40 against the skirt portion S of the vehicle T with a predetermined sliding contact pressure. The rotation direction of the rotating brush 40 is opposite to the traveling direction of the vehicle T, that is, the brush 40.
The sliding contact direction is set to be opposite to the traveling direction A of the vehicle T.

In the operation of the cleaning apparatus 1 in the above-described embodiment, in the case of a two-story vehicle T as shown in FIG. 9, that is, in the case where the side surface Ts is formed with a large inclination in the vertical direction, The elevating frame 9 is operated so as to bring the rotating brush 40 into contact with the skirt portion S below the side surface thereof, and is controlled so as to set the inclination angle of the support frame 24 to a small value, as shown in FIG. In the case of the vehicle described above, the elevating frame 9 is further raised due to the shape of its side surface as compared with the case of the above-mentioned two-story vehicle, the inclination angle is set to be large, and the rotating brush 40 is controlled to contact.
In addition, when there is such a difference in vehicle type, the rotating brush 4
Since there is a large difference in the overhanging distance of 0 to the track L side, the stopper 33 of the segment gear 32 is controlled.

The distance that the rotary brush 40 advances to the side of the orbit L is such that the stopper 33 of the segment gear 32 provided on the swivel shaft 31 has the short air cylinder built therein as described above. Therefore, when the piston rod 33a is extended as shown in FIG. 10, the advancing angle of the rotary brush 40 becomes small as shown by the chain line in FIG. 7, and the piston rod 33a is retracted. When it is moving, the rotary brush 40 largely advances to the track L side as shown by the chain double-dashed line in FIG. That is, since the regulation position of the turning angle of the turning shaft 31 can be set stepwise, when the distance from the cleaning device 1 to the skirt portion S of the vehicle T on the track L varies depending on the vehicle type. Is this stopper 33
Is working.

In this embodiment, since the vehicle T to be cleaned is of two types, a one-story vehicle and a two-story vehicle, the distance between the skirt S and the cleaning device 1 is short in a one-story vehicle. Therefore, in order to reduce the turning angle of the turning shaft, the stopper 33
Is activated, and the distance between the skirt portion of the two-story vehicle and the cleaning device is larger than that of the one-story vehicle, the rotary brush 40 is advanced with the piston rod 33a of the stopper 33 retracted. ..

Therefore, in the skirt cleaning device 1 thus constructed, the outer shape of the vehicle T moving on the track L is detected by the detecting portion, and the rotating brush 4 for the vehicle T is detected.
The position of the rotating brush 40 is moved to the most suitable position by operating the lifting drive unit 11 and the inclination angle adjusting unit 17 at the contact angle of 0 and the height thereof. Since the skirt portion S can be always effectively cleaned, cleaning unevenness does not occur, and the rotating brush 40 accurately abuts the side surface skirt portion S even for a vehicle having a different outer shape of the vehicle T, for example. It is possible to obtain a sufficient cleaning effect for a vehicle of any shape. Also,
Since the rotating brush 40 is controlled so as to always slide on the surface of the skirt portion S of the vehicle, the rotating brush 40 does not come into contact with the device portion provided below the skirt portion S, that is, below the vehicle T. It is like this.

[0030]

As described above, in the method and apparatus for cleaning a skirt portion on the side surface of a vehicle according to the present invention, the outer shape of the vehicle moving along the track is detected by the detecting portion, and the angle at which the rotating brush abuts the vehicle. The height of the rotary brush and the height of the rotary brush can be moved to the most suitable position by operating the lifting drive unit and the tilt angle adjusting unit. The effect is that effective cleaning can always be performed. Further, as a result, the skirt portion of the vehicle does not have uneven cleaning, and even if the vehicle has a different outer shape, the rotating brush always abuts the side skirt portion accurately. Also, there is an effect that a sufficient cleaning effect can be obtained. Further, since the rotating brush is controlled by the detecting unit so that the rotating brush always comes in contact with the surface of the skirt portion of the vehicle, the rotating brush does not contact the device portion arranged below the skirt portion, that is, the lower portion of the vehicle. Thus, there is an effect that the cleaning work is automatically performed.
