DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS As shown in FIGS. 1, 2, and 3, a rail 15 is laid under the approach path 2 from which the vehicle 1 enters, and the vehicle 1 runs on the rail 15. ing. A work platform 16 is arranged on the side of the approach path 2. In the case of the present embodiment, a cleaning device A for cleaning the upper portion of the front surface 1a other than the skirt portion 1b as a device for cleaning the front surface 1a of the vehicle 1 and a cleaning device B of the present invention for cleaning the skirt portion 1b are installed. I have. Since the cleaning devices A and B of this embodiment are devices that clean only one of the left and right sides of the front surface of the vehicle 1, it is preferable to provide the cleaning devices A and B on both the left and right sides, respectively.

The cleaning device A for cleaning the upper portion is constructed as follows. A moving base 17 is provided on the working platform 16 so as to be parallel to the longitudinal direction of the vehicle 1. A base plate 18 is mounted on the moving base 17 on the moving base 17. A work robot 19 is mounted on the base plate 18 so as to be movable in the longitudinal direction. The working robot 19 is a robot controlled by six axes,
The manipulator 20 of the working robot 19 moves in the same manner as a human finger. A cleaning brush 21 is rotatably mounted on the manipulator 20, and the cleaning brush 21 is rotationally driven to perform cleaning. The work robot 19 is program-controlled by a robot controller 22. That is, the cleaning brush 21 is controlled so as to move in accordance with the shape of the front surface 1a of the vehicle 1, and the shape of the front surface 1a is preliminarily taught. Then, by driving the work robot 19 and the cleaning brush 21, the front surface 1a of the vehicle 1 is cleaned. At this time, the working robot 19 operates following the teaching according to the type of the vehicle 1, and the front surface 1 a is cleaned by the cleaning brush 21.

The cleaning device B for cleaning the lower skirt portion 1b is configured as follows. A work rail 3 is laid parallel to the rail 15 on the side of the rail 15 on which the vehicle 1 travels, and a bogie 4 is mounted along the work rail 3 so as to be able to travel freely. As shown in FIGS. 4, 5 and 6, wheels 7 that roll along work rails 15 are rotatably mounted on the trolley 4, and the drive motor 2 mounted on the trolley 4
4 is driven via the sprockets 25 and 26, the chain 27 and the axle 42. This axle 4
2 is provided with a clutch 43. When the clutch 43 is engaged, the drive motor 24 and the wheel 7 are interlocked. When the clutch 43 is disengaged, the wheel 7 and the axle 42 rotate freely, and the bogie 4 is manually operated.
Can be moved. A rotating shaft 9 is erected on the cart 4 so as to face the vertical direction. The rotating shaft 9 is rotatably supported by a bearing 28, and the upper end of the rotating shaft 9 is located above the upper surface of the cart 4. It is projected to. The arm 5 is horizontally arranged on the upper surface of the carriage 9, and the base end of the arm 5 is fixed to the upper end of the rotating shaft 9.
At the tip of the arm 5, a spray nozzle 6 for spraying cleaning water to perform cleaning is mounted. Up and down elevating means comprising a jack 29 is provided on the upper surface of the tip of the arm 5, and the injection nozzle 6 is mounted on an elevating base plate 30 on the upper surface of the jack 29. The injection nozzle 6 is a rotary injection nozzle 6a in the present embodiment, and has a plurality of injection ports 31. A cleaning water supply pipe is connected to the rotary spray nozzle 6a via a rotary joint 32. The injection nozzle 6 is not limited to the rotary injection nozzle 6a, but may be a fixed injection nozzle 6b as shown in FIG.

A reduction gear 33 is installed in the carriage 4, and an input shaft 34 of the reduction gear 33 and the drive motor 24 are linked via sprockets 35 and 36 and a chain 37. The disc-shaped cam plate 8 is detachably attached to the output shaft 38 of the reduction gear 33 with attachment screws 39. When the drive motor 24 is driven, the cam plate 8 is driven to rotate in synchronization with the rotation of the wheels 7. A spiral cam groove 40 is formed in the cam plate 8. Since the shape of the curved surface of the skirt portion 1b differs depending on the type of the vehicle, a plurality of types of the cam plates 8 are required, and a plurality of types having the cam grooves 40 corresponding thereto are prepared. An interlocking body 45 movably in the horizontal direction is disposed between the cam plate 8 and the rotating shaft 9, and a cam follower 46 is mounted on one end of the interlocking body 45, and the cam follower 46 is inserted into the cam groove 40. It slides along. In the vicinity of the cam plate 8, a micro switch 47 for detecting when the cam follower 46 is located at the starting point 40a of the cam groove 40 and a micro switch 48 for detecting when the cam follower 46 is located at the ending point 40b of the cam groove 40 are provided. is there. A rack 50 is provided on the other end side of the interlocking body 45, and a pinion 51 is mounted on the rotating shaft 9, and the rack 50 is meshed with the pinion 51. When the cam plate 8 rotates, the interlocking body 45 moves left and right by the cam groove 40, and the movement of the interlocking body 45 causes the rotation shaft 9 to rotate via the rack 50 and the pinion 51, and the rotation shaft 9 rotates. The rotation causes the arm 5 to rotate. Accordingly, the arm 5 rotates according to the shape of the cam groove 40 of the cam plate 8, and the injection nozzle 6 of the arm 5 moves according to the curved surface of the skirt portion 1b. In FIG. 1, 54 is a high-pressure injection pump unit, 55 is an injection water tank, 56 is a chemical solution tank,
Reference numeral 7 denotes a washing finish water tank.

Next, the operation of the cleaning apparatus B configured as described above will be described. In a state where the carriage 4 is moved to the initial position, washing water is injected from the injection nozzle 6 and the driving motor 2
4 is driven. The wheels 7 are rotated by the drive of the drive motor 24, and the carriage 4 moves at a constant speed, and moves while injecting the washing water from the injection nozzle 6. On the other hand, the cam plate 8 is rotationally driven in synchronization with the movement of the carriage 4 by the rotation of the drive motor 24,
The arm 5 rotates via the interlocking body 45 and the rotating shaft 9, and the injection nozzle 6 moves so as to follow the curved surface of the skirt portion 1b. In this manner, the cleaning can be automatically performed by moving the injection nozzle 6 along the skirt portion 1b. When the type of vehicle to be washed is changed, the cam plate 8 is replaced with the corresponding one and the corresponding movement is performed. When the height of the injection nozzle 6 is changed by the jack 29, the vertical position for cleaning can be freely adjusted.

[0015]

As described above, according to the present invention, a bogie is movably arranged on a work rail provided parallel to the longitudinal direction of the vehicle on the side of the approach path where the vehicle enters, and the bogie is placed on a horizontal plane. The rotating arm is rotatably mounted and an injection nozzle for injecting washing water is provided at the end of the arm. The movement of the carriage and the arm are such that the injection nozzle follows the curved surface of the front of the vehicle as the carriage moves. since the rotation is tuned, by moving the carriage while injecting wash water from the injection nozzle, the injection nozzle be one washed with washing water while moving to follow the front surface of the curved surface of the vehicle, the injection The nozzle can be moved automatically along the curved surface of the front surface, and can be cleaned automatically.It requires no labor as in the past, and can be operated safely and can be cleaned without getting the operator wet or dirty.
