Next, a method of cleaning the vehicle body 30 of the Shinkansen vehicle using the railway vehicle cleaning device 10 will be described. The body 30 of the Shinkansen vehicle is washed according to the following steps P1 to P5. If possible, the steps P1 to P5 may be executed in a different order or may be executed in parallel.

(Process P1)
This step P1 is a step in which the worker prepares for the cleaning work.
The operator operates the operation switch to drive the drive wheel 184, and moves the railway vehicle cleaning device 10 to the position where the guide rail 44 is located.
Next, the operator lowers the guide rail receiving wheel 130, puts it on the guide rail 44, and moves the railway vehicle cleaning device 10 along the guide rail 44 to the vicinity of the vehicle body 30.
Further, in addition to the railway vehicle cleaning device 10, a detergent spraying device (not shown) for spraying the detergent is prepared.

(Process P2)
This step P2 is a step of spraying the detergent.
An operator sprays detergent toward the vehicle body 30 using a detergent spraying device (not shown). Dirt adhering to the vehicle body 30 is lifted by the sprayed detergent.

(Process P3)
This step P3 is a step of washing the vehicle body 30 with water.
First, the operator moves the railway vehicle cleaning device 10 to the place where the detergent of the vehicle body 30 is sprayed.
Next, by the operation of the operator, the wiping bodies 124a, 124b, 124c, 124d and the wiping bodies 126a, 126b advance toward the vehicle body 30 and come into contact with the predetermined wiping positions, respectively. With the advance of the wiping body 126a, the first nozzle and the second nozzle also advance. Further, the limit switches 134b and 134c advance and come into contact with the side surface of the vehicle body 30, respectively.
Next, by the operation of the operator, the water spraying portion (not shown) has the spraying ranges A1 and A2 (an example of the first spraying range) and the spraying ranges B1 and B2 (second) shown in FIG. 4 (A). Spray water toward an example of the spray range).
Subsequently, the wiping bodies 124a, 124b, 124c, 124d wipe the car body 30 to which the detergent is attached, and the wiping bodies 126a, 126b wipe the car body 30, and the detergent containing stains due to the water sprayed by the water spraying portion is used. Be washed away. On the other hand, the railroad vehicle cleaning device 10 is driven by the drive wheels 184 and travels along the guide rail 44.
Since the railroad vehicle cleaning device 10 moves stably along the guide rail 44, the contact state between the wiping bodies 124a, 124b, 124c, 124d and the wiping bodies 126a, 126b and the vehicle body 30 is stably maintained. Ru.

(Process P4)
This step P4 is a step of cleaning the door 302.
When the limit switches 134b and 134c detect the position of the door 302 as the railroad vehicle cleaning device 10 travels, the advance / retreat mechanisms 132b, 132c and 132d are controlled by a controller (not shown), and the corresponding wiping bodies 124b. , 124c, 124d further advance and wipe the door 302.

As described above, since the advancing / retreating mechanisms 132b, 132c, and 132d have essentially the same mechanism, the operation of the advancing / retreating mechanism 132b of the wiping body 124b will be described in detail below with reference to FIG.
The advancing / retreating mechanism 132b operates as shown in the order of FIGS. 5 (A) to 5 (D) as the railroad vehicle cleaning device 10 travels in the direction of the arrow (X direction) shown in FIG.

As shown in FIG. 5A, when the wiping body 124b is in the position on the front side of the door 302, the limit switch 134b contacts the surface of the vehicle body 30 and detects that it is not the position of the door 302 and controls it. The air cylinder 138 is advanced to the side opposite to the Y direction based on the command of the vessel (not shown). As a result, the contact member 146 stays at the position Y1, and the amount of advancement of the air cylinder 136 for advancing the wiping body 124b via the contact member 146 is limited. In such a state, the wiping body 124b comes into contact with the surface of the vehicle body 30 and performs a wiping operation.

As shown in FIG. 5B, when the railroad vehicle cleaning device 10 is further moved and the wiping body 124b is in a position where it has passed the rear end portion (end portion on the X-direction side) of the door 302, the limit is reached. When the switch 134b comes into contact with the door 302 and detects that it is in the position of the door 302, the air cylinder 138 retracts in the Y direction based on the command of the controller (not shown). As a result, the contact member 146 moves to the position Y2, which is closer to the vehicle body 30 than the position Y1, and the air cylinder 136 further advances. In such a state, the wiping body 124b contacts the surface of the door 302 located at a position deeper than the surface of the vehicle body 30 and performs the wiping operation.

As shown in FIG. 5 (C), when the railroad vehicle cleaning device 10 is further moved and the wiper 124b is located at the front end of the door 302 (the end opposite to the X direction), the limit is reached. When the switch 134b comes into contact with the surface of the vehicle body 30 and detects that it is not the position of the door 302, the air cylinder 138 advances to the side opposite to the Y direction and the air cylinder is moved to the side opposite to the Y direction based on the command of the controller (not shown). 136 retracts more than the amount of advance of the air cylinder 138, and the contact member 146 separates from the air cylinder 138. In such a state, the wiping body 124b is separated from the surface of the door 302 and further away from the position of the surface of the vehicle body 30. However, the wiping operation of the wiping body 124b away from the door 302 is continued.
When a predetermined time T elapses after the limit switch 134b comes into contact with the surface of the vehicle body 30 and detects that the position is not the position of the door 302, the air cylinder 136 of the vehicle body 30 is as shown in FIG. 5 (D). Advance to the side. However, the amount of advancement is limited at the position Y1 where the contact member 146 comes into contact with the air cylinder 138. As a result, the wiping body 124b comes into contact with the surface of the vehicle body 30. The state shown in FIG. 5 (D) is the same as the state shown in FIG. 5 (A).
That is, when it is determined that the controller (not shown) has moved from the position of the door 302 to the position of the vehicle body 30 based on the detection signal output by the limit switch 134b, the air cylinder 136 is driven and determined in advance. By separating the wiping body 124b from the vehicle body 30 until the time T elapses, the railway vehicle cleaning device 10 can move over the step between the vehicle body 30 and the door 302.

After that, every time the door 302 is passed, FIGS. 5 (A) to 5 (C) are repeated to clean not only the surface of the vehicle body 30 but also the door 302 provided at a recessed position.
During the cleaning work, sound flows from the speaker provided in the railway vehicle cleaning device 10.
However, the flowing sound is set to be different depending on the detection signals of the limit switches 134b and 134c. That is, different sounds flow while the wiping bodies 124b, 124c, and 124d are wiping the vehicle body 30 and while the door 302 is being wiped.

(Step P5)
This step P5 is a step of finishing the cleaning work.
By the operation of the operator, the spraying of water is stopped and the wiping bodies 124a, 124b, 124c, 124d and the wiping bodies 126a, 126b are retracted.
After the operator floats the guide rail receiving wheel 130, the operator runs the floor surface 40 to return the railway vehicle cleaning device 10 to a predetermined position.

As described above, the railway vehicle cleaning device 10 according to the present embodiment has high work efficiency because the Shinkansen vehicle is cleaned by traveling along the vehicle body 30 to which the detergent is sprayed.
