  However, the shape of streamlined railway vehicles such as the Shinkansen has become more complicated due to higher speed. For this reason, according to the conventional car wash machine, there is a problem that unwashed portions are generated between the area where the top brush contacts and the area where the side brush contacts. Moreover, since the pair of top brushes and the pair of side brushes are provided, there is a problem that the cost of the car wash machine increases.

  It is an object of the present invention to provide a car wash machine that can reduce unwashed waste and reduce costs.

  In order to achieve the above object, the present invention provides a car wash machine for washing a streamlined railway vehicle, and a pair of rotating brushes that can move both sides of the railway vehicle in the front-rear direction and tilt the rotation axis in a vertical plane. A storage unit for storing the shape of the railway vehicle in advance, and the rotary brush is configured to change the height of the rotary brush and the inclination angle of the rotary shaft based on the shape of the railway vehicle while moving in the front-rear direction. The top and side surfaces of the vehicle are washed.

  According to this configuration, the shape of the railway vehicle is stored in advance in the storage unit. When cleaning of the railway vehicle is started, the rotating brush moves in the front-rear direction on the side of the railway vehicle, and the cleaning is performed while varying the height of the rotating brush and the inclination angle of the rotating shaft according to the shape of the railway vehicle.

  In the car wash machine having the above-described configuration, the rotating brush moves backward at one end or both ends of the traveling range of the rotating brush, and then reversely moves for cleaning. According to this configuration, the rotating brush moves downward and cleans while meandering from the top surface to the side surface of the railway vehicle.

  In the car wash machine having the above-described configuration, the rotating brush extends to the other side of the center line of the railway vehicle when the angle of inclination of the rotating shaft is leveled, and one rotating brush is in relation to the other rotating brush. Move back and forth with a delay.

  According to this configuration, the cleaning areas of the top surface by both rotary brushes overlap, and one of them is delayed, so that interference between the two is prevented.

  According to the present invention, the rotary brush can change the height of the rotary brush and the inclination angle of the rotary shaft inclined in the vertical plane based on the shape of the railway vehicle while moving in the front-rear direction. Since it is washed, it is possible to reduce unwashed waste and reduce the cost of the car wash machine.

  Embodiments of the present invention will be described below with reference to the drawings. 1 and 2 are a front view and a plan view showing a cleaning unit 1 of a car wash machine WA according to an embodiment of the present invention. The car wash machine WA includes a main body unit 10, a cleaning unit 1, and a drying unit 50 (see FIG. 3), and cleans a streamlined railway vehicle TR such as a Shinkansen.

  A streamlined railway vehicle TR such as a bullet train has wheels 102 and a pantograph 100, and the wheels 102 roll on a rail 103. Thereby, the railway vehicle TR can move in the front-rear direction. The pantograph 100 is provided on the top surface of the railway vehicle TR, and the railway vehicle TR is supplied with power by being connected to the overhead line 101.

  The main body 10 extends up and down and is erected, and a pair is provided on both sides of the railway vehicle TR. On the ground G in the main body 10, a rack 2 extending in the front-rear direction is provided. A rail 7 extending in the front-rear direction is provided on the upper surface 10 a in the main body 10.

  The cleaning unit 1 is provided in each of the main body units 10, and two support columns 5 extending vertically are arranged on the front and rear sides. Further, the cleaning unit 1 is provided with a storage unit (not shown) for storing the shape of the railway vehicle TR and a water purification nozzle (not shown) for injecting cleaning water to the railway vehicle TR.

  The support column 5 has a leg portion 6 having a pinion 3, and a groove portion (not shown) is provided at the upper end. The groove is fitted to the rail 7, the pinion 3 is engaged with the rack 2, and the cleaning unit 1 moves in the front-rear direction with respect to the railway vehicle TR.

  A holding portion 8 is supported on the front and rear columns 5 so as to be movable up and down. The holding unit 8 moves in the vertical direction along the column 5 by a driving unit (not shown). The rotating brush 4 is held by the holding unit 8. The rotating brush 4 is formed by radially fixing brush hairs (not shown) to the rotating shaft 4b.

  Further, the rotating brush 4 is disposed so as to be tiltable in the left-right direction within the vertical plane around the shaft portion 4a. Thereby, the rotating brush 4 makes the inclination angle θ of the rotating shaft 4b variable. Further, the rotating brush 4 extends to the other side of the center line 104 of the railway vehicle TR when the rotating shaft 4b is horizontal (θ = 0 °).

  The rotating brush 4 brushes the railway vehicle TR while changing the height and the inclination angle θ of the rotating shaft 4b based on the shape of the railway vehicle TR stored in the storage unit. At this time, the rotating brush 4 is controlled so as not to come into contact with the pantograph 100 or the overhead wire 101 provided on the upper part of the railway vehicle TR.

  FIG. 3 shows a front view of the drying unit 50. The drying unit 50 is attached to the main body unit 10 and disposed outside the traveling range L of the cleaning unit 1. The drying unit 50 includes a pair of left and right sensors (not shown) and a drying blower 51. The sensor is formed by a photoelectric sensor and detects the railway vehicle TR moving on the rail 103. The drying blower 51 generates an air flow, applies the air flow to both sides of the rail vehicle TR, and dries the rail vehicle TR that moves in the front-rear direction.

  In the car wash machine WA having the above-described configuration, the cleaning unit 1 travels on the rack 2 and the cleaning unit 1 cleans the railway vehicle TR. 4 and 5 are a side view and a plan view showing a car washing operation of the railway vehicle TR.

  In step S1, the rotating brush 4 is disposed horizontally with the inclination angle θ of the rotating shaft 4b set to 0 °, and the cleaning unit 1 starts cleaning from the front end of the railway vehicle TR. At this time, as shown in FIG. 5, one rotating brush 4 moves in the front-rear direction with a delay relative to the other rotating brush 4.

  The rotating brush 4 extends to the other side of the center line 104 of the railway vehicle TR when the rotating shaft 4b is leveled. For this reason, in the place where the cleaning area of the rotating brush 4 overlaps, the cleaning power can be improved and the interference between the two can be prevented.

  In step S2, as compared with step S1, the height of the rotating brush 4 and the inclination angle θ of the rotating shaft 4b are increased to clean the top surface of the railway vehicle TR. After that, cleaning is performed by increasing the height of the rotary brush 4 and the inclination angle θ of the rotary shaft 4b, and the process moves to step S3 at the end of the travel range L of the rotary brush 4. Thereby, the rotating brush 4 can wash | clean the top | upper surface of the railway vehicle TR. Note that the height of the rotating brush 4 and the inclination angle θ of the rotating shaft 4 b are set so that the rotating brush 4 does not contact the pantograph 100 or the overhead wire 101.

  After step S3, the rotating brush 4 moves downward and proceeds to step S4. From step S4, the rotating brush 4 moves backward, and the height of the rotating brush 4 and the inclination angle θ of the rotating shaft 4b are reduced to clean the side surface of the railway vehicle TR.

  In step S5, as compared with step S4, the rotating brush 4 is cleaned by reducing the height and the inclination angle θ of the rotating shaft 4b. As a result, the rotating brush 4 reduces the amount of unwashed corresponding to the shape of the streamlined railway vehicle TR.

  The rotating brush 4 moves to the front end of the railway vehicle TR, and then the rotating brush 4 moves backward again. Then, the rotating brush 4 again increases the height and the inclination angle θ of the rotating shaft 4b to clean the remaining side surface of the railway vehicle TR. In this way, the rotating brush 4 moves downward and cleans while meandering from the top surface to the side surface of the railway vehicle TR.

  When the cleaning of the cleaning unit 1 is completed, the railway vehicle TR moves on the rail 103. When the railway vehicle TR is detected by the detection sensor, the airflow flows out from the drying unit 50 and drying of the railway vehicle TR is started.

  According to the present embodiment, the rotating brush 4 changes the height of the rotating brush 4 and the inclination angle θ of the rotating shaft 4b inclined in the vertical plane based on the shape of the railway vehicle TR while moving in the front-rear direction. Since the top and side surfaces of the TR are washed, it is possible to reduce the amount of unwashed and the cost of the car wash machine WA.

  Moreover, since the rotary brush 4 moves downward at one end or both ends of the travel range L of the rotary brush 4 and then reversely cleans, the top and side surfaces of the railway vehicle TR can be cleaned.

  Further, when the rotating brush 4 leveles the inclination angle θ of the rotating shaft 4b, the rotating brush 4 extends to the other side of the center line 104 of the railway vehicle TR, and one rotating brush 4 is delayed with respect to the other rotating brush 4 in the direction. Therefore, it is possible to prevent the interference between the two and improve the cleaning power in the cleaning region where the railway vehicle TR overlaps.

  Further, the rotating brush 4 may increase or decrease the inclination angle θ of the rotating brush 4 or the rotating shaft 4b in the middle of the travel range L according to the shape of the railway vehicle TR.

  ADVANTAGE OF THE INVENTION According to this invention, it can utilize for a car wash machine provided with the rotating brush which wash | cleans a streamline railway vehicle.
