Conventionally, when cleaning the front and rear surfaces of railway vehicles,
Most of the work was done manually. However, manual vehicle cleaning work involves work at heights, which poses problems in that it is dangerous and complicated.

Therefore, in recent years, various cleaning devices have been devised to automate the cleaning of the front and rear surfaces of vehicles.

For example, in a vehicle washing device disclosed in Japanese Patent Publication No. 49-33152, a vertical rotating brush is supported at the tips of two support links to wash a vehicle. This device uses a spring or air cylinder as a means to apply sliding contact pressure to the rotating brush, and rotates the support link at a predetermined sliding contact pressure to clean the front and rear surfaces of a stopped vehicle. ing.

Further, the cleaning device disclosed in Japanese Utility Model Publication No. 44-6227 is an example in which a torque motor is used as the swing driving means for the support link of the cleaning device.

On the other hand, as shown in FIG.
is a rotating brush 4 provided adjacent to the drive unit 31 and rotated by a torque motor 32.
It is designed to accommodate 3.

Next, the operation of each device having the above configuration will be explained.

When operating the front cleaning device 1, first,
The solenoid valve 14 is energized based on the control signal. Then, through this solenoid valve 14, the air accumulator 1
2 is sent into the air cylinder 15 from the tip port 15b of the air cylinder 15, and moves the piston rod 18 in the retraction direction. As shown in FIG. 7a, the angle D between the line L connecting the brush rotation shaft 25 and the turning shaft 21 and the vehicle traveling direction A, that is, the rail 3, is a right angle. The brush arm 24 is pivoted from the stored state to a cleaning standby position and is kept on standby. At this time, the rotating brush 26 has already started rotating.

Vehicle 4 moves forward while maintaining a low speed.
The front surface 4F of contacts the rotating brush 26. At this time, the brush arm 24 is pushed back by the force generated upon contact and becomes bound, but due to the elasticity of the rotating brush 26 itself and the pressure increase in the area cylinder 15, the brush arm 24 pivots. The restraining force generated by the pressing force of the rotating brush 26 against the front surface 4F of the vehicle alleviates the bound state.

As the vehicle 4 moves forward, the rotating brush 26 is moved backward, and at the same time, an appropriate sliding contact pressure is always maintained by the turning torque of the brush arm 24 generated by the force that tries to maintain the retracted state of the area cylinder 15. 4 is cleaned.

However, as shown in FIG. 7b, if the angle between the traveling direction A of the vehicle 4 and the direction T in which the turning torque of the brush arm 24 acts is θ, then the angle D becomes 90°.
If the vehicle 4 becomes smaller, the brush arm 2
The force applied to 4 increases in proportion to 1/COSθ with respect to the turning torque of the brush arm. In other words, the brush arm 24 connects the rotating brush 26 to the vehicle 4.
The force that pushes the vehicle 4 is actually the rotating brush 2.
The force in the direction of pushing 6 away increases in proportion to 1/COSθ. In other words, as the angle D becomes smaller, the force that the vehicle 4 applies to the brush arm 24 increases.

Therefore, as the vehicle 4 moves further and the rotating brush 26 is pushed back until the angle D reaches an appropriate angle (approximately 45 degrees) as shown in FIG. The limit switch 28 detects the cam 27 installed and set in advance. Then, based on that signal, the control signal stops energizing the solenoid valve 14 . The de-energized solenoid valve 14 sends compressed air from the air accumulator 12 to the proximal port 15c of the air cylinder 15 to actuate the piston rod 18 in the extension direction. Then, the brush arm 24 starts rotating in the direction B of the storage unit 10 at a predetermined speed by the speed controller 17. At this time, the pressing force and sliding contact pressure of the rotating brush 26 against the front surface 4F of the vehicle 4 are kept constant by the pressing force on the rotating brush 26 due to the vehicle progress and the turning speed of the brush arm 24 by the speed controller 17. It's starting to become easier.

As the vehicle 4 further advances, the brush arm 24 swings to just before the retracted position, as shown in FIG. 7c, and finishes cleaning the front surface 4F. When the brush arm 24 is retracted as shown in FIG. 7d, the piston rod 18 of the air cylinder 15 maintains its extended state, and the rotary brush 26 is stored and fixed in the storage unit 10.

Note that the sliding pressure of the rotating brush 26 against the front surface 4F of the vehicle is set so as not to damage the wiper provided on the front window of the vehicle.

Next, while the side surface 4S of the vehicle 4 is passing, the rear surface cleaning device 2 does not operate because no control signal is issued, and as shown in FIG. 8a, the brush arm 41 locking mechanism 4 in the stored position
4, it is in a fixed state. At this time, the rotating brush 43 is in sliding contact with the vehicle side surface 4S.

When the vehicle 4 moves forward and the rear surface 4R of the vehicle 4 approaches the cleaning device 2, a control signal is sent to the locking mechanism 44, actuating the first solenoid valve 50, and locking the locking pin 46 as shown in FIG. 6b. Press down.

At the same time, the torque motor 32 is activated. Also the second
The solenoid valve 63 is activated to send compressed air to the initial speed increasing cylinder 60, which slides into contact with the vehicle side surface 4S.
At this time, the brush arm 41 is connected to the torque motor 3.
Turning torque due to 2 is beginning to be generated.

When the vehicle 4 further advances and the corner 4C of the rear surface 4R of the vehicle passes the rotating brush 43 as shown in FIG. 8B, the brush arm 41 starts to rotate in the F direction by the torque motor 32.

However, the initial rotation speed of the torque motor 32 is 0.
Therefore, it does not synchronize with the traveling speed of vehicle 4, and
The smaller the angle E between the brush arm 41, the rail 3, and the vehicle traveling direction A, the slower the turning speed of the brush arm 41 relative to the traveling speed of the vehicle 4.
The brush arm 41 cannot follow the speed of the vehicle 4.

Therefore, the initial speed increasing cylinder 60 presses and energizes the protruding pawl 37 of the segment gear 34 (arrow G in FIG. 5) to compensate for the acceleration of the rotation of the brush arm 41 by the torque motor 32, and forcibly force the brush arm 41 is turned to press the rotating brush 43 against the rear surface 4R of the vehicle. At this time, if the initial speed of turning by the initial speed increasing cylinder 60 is too high, the pressure of the compressed air is lowered and adjusted, and the pressing force and sliding contact pressure of the rotating brush 43 against the rear surface 4R of the vehicle are
It is adapted to be adjusted by the control voltage of the torque motor 32. The forced turning by the initial speed increasing cylinder 60 is performed until the angle E from the start of turning of the brush arm 41 reaches about 30° to 40° (approximately 1/3 of the width of the rear surface of the vehicle), as shown in FIG. 8c.

At this time, since the torque motor 32 has already obtained an appropriate rotational speed and turning torque, cleaning is performed while pressing the brush arm 41 against the rear surface 4R of the vehicle as the vehicle 4 moves in the A direction.

While rotating the brush arm 41, the rear surface of the vehicle 4R
The cleaning ends when the angle E between the brush arm 41 and the rail 3 reaches approximately 90° as shown in FIG. 8d.

After cleaning is completed, the torque motor 32 rotates in the reverse direction to return the brush arm 41 to the retracted position. At this time, each electromagnetic valve 50, 63 does not operate because it is not energized.

When the brush arm 41 returns to the retracted position as shown in FIG. 8a, the protruding pawl 37 provided on the segment gear 34 of the pivot shaft 38 comes into contact with the tip of the piston rod 61 of the initial velocity increasing cylinder 60 immediately before the retracted position. . At this time, compressed air remains in the cylinder 60, which acts as a shock absorber when the brush arm 41 stops rotating, thereby weakening the impact when the brush arm 41 is retracted so that it can be retracted.

When the brush arm 41 is retracted, the segment gear 3
The guide slope 36 formed in the lock pin 46 guides the tip 46a of the lock pin 46, and at the same time the lock pin 46 is pushed down. At the retracted position, the lock pin 46 is fitted into the lock hole 35 of the segment gear 34 by a spring 47, as shown in FIG. This lock mechanism 44
According to the above, the fixed state of the brush arm 41 is not released unless the power of the solenoid valve 50 is turned on, so that the brush arm 41 may be moved from inside the storage unit 30 to the vehicle traveling side due to an erroneous operation or an external force such as wind or an earthquake. It doesn't stick out.

Note that during the operation of each of the above-mentioned devices 1 and 2, spraying and application of detergent and chemical solution, and each rotating brush 26 and 43 are performed.
Needless to say, washing with water and the like are performed.

In this embodiment, in the front cleaning device, the rail 3
When the angle D between the brush arm 24 and the brush arm 24 becomes approximately 45°, the limit switch 28 detects the cam 27,
Although the example in which the piston rod 18 is operated in the extension direction has been described, this angle D can be adjusted depending on the shape of the vehicle to be cleaned, the speed of travel of the vehicle, etc.

〔Effect of the invention〕

As explained above, according to the front and rear surface cleaning device for a rail vehicle according to the first invention of the present application, the front surface of the rail vehicle is cleaned from approximately the center to one side by the rotating brush 26 of the one side front surface cleaning device. The area from the approximate center to the other side is cleaned by the rotating brush 26 of the other side front cleaning device installed on the other side of the track at a position shifted forward and backward from the one side front cleaning device, and further, the track vehicle The rear surface is cleaned from approximately the center to one side by the rotating brush 43 of the one side rear surface cleaning device, and from approximately the center to the other side, the trajectory at a position shifted forward and backward from the one side rear surface cleaning device is cleaned. Since the cleaning is performed by the rotating brush 43 of the other side front cleaning device provided on the other side, the rotating brush 26 or the rotating brush 43
The length of the brush arm 24 or brush arm 41 is half the front and rear width of the track vehicle, and the length of the brush arm 24 or brush arm 41 is half the front and rear width of the track vehicle, and the length of the brush arm 24 or the brush arm 41 is half of the front and rear width of the track vehicle. This has the effect that the parts can be cleaned evenly and efficiently with substantially uniform sliding contact pressure.

Further, according to the front and rear surface cleaning device for a track vehicle according to the first invention of the present application and the rear surface cleaning device for a track vehicle according to the third invention, when cleaning the rear surface of the vehicle in a traveling state, it is possible to clean the rear surface of the vehicle from the storage position. When rotating the rotary brush 43 to the cleaning standby position, the tip contact portion 64 of the initial velocity increasing cylinder 60 rotates the rotating shaft 3.
The protruding pawl 37 provided on the outer periphery of the rotary brush 43 is pressed and biased to compensate for the rotational movement speed of the rotating brush 43 via the rotating shaft 38. The effect is that the rear surface of the vehicle can be efficiently washed while being pressed and followed by the torque motor 32.

Furthermore, according to the front surface cleaning device for a track vehicle according to the second invention of the present application, the angle of the pivot shaft 21 is adjusted by the cam 27 and the limit switch when the rotary brush 26 is pushed back by a predetermined angle as the vehicle advances. Since the rotary brush 26 is detected by a limit device having 28 and rotated in the retracting direction, there is no waste of the rotary brush 26 continuing to clean the side of the vehicle after the front surface cleaning is completed, and this is done efficiently. It is possible to wash the front of a moving vehicle.
