The suspension line 2 is provided corresponding to the trolley line T and the up and down lines of the trolley line T and the suspension line M in the station premises. At one end of the suspension line 2, a maintenance area 2 a for waiting the oil applicator 3 is provided. The maintenance area 2a is retained on the support such as the beam 15 above the suspension line M via the insulator 2b outside the vertical line.

  The number of the oil applicators 3 corresponding to the pantograph of the train scheduled to arrive is set in advance. As shown in FIGS. 3 to 5, the oil applicator 3 has four support arms 4 on the front, rear, left, and right, and supports traveling rollers 5 as traveling means on the upper part. The traveling roller 5 is hung on the suspension line 2 by an annular recess on the peripheral surface, and rolls on the suspension line 2 by driving a motor (not shown) to move the oil applicator 3 along the suspension line 2.

  The oil applicator 3 includes a tank 6 and an oil injector 7 which are oil injection means. The tank 6 is fixed in the main body 3 a of the oil applicator 3 and stores oil to be injected onto the trolley wire T. A pair of front and rear oil injectors 7 are provided below the oil applicator 3 corresponding to the two-pantograph system of the pantograph, and each has a plurality of nozzles 7b that eject oil to the lower surface of a rectangular box-shaped outer frame 7a. The nozzles 7b are arranged in a line at almost equal intervals in a direction orthogonal to the traveling direction of the oil applicator 3, and are provided in accordance with the width of the boat body P1 of the pantograph P (the length in the direction orthogonal to the line). . The nozzle 7b communicates with the tank 6 through an oil passage pipe 7c. The oil passage pipe 7c can be expanded and contracted in accordance with the vertical movement of the oil injector 7.

  The oil injector 7 is provided via an elevating means 8 in order to move up and down between a predetermined original position supported by the main body 3a and an oil injection position approaching the trolley line T away from the main body 3a. The lifting / lowering means 8 includes a winder 8a disposed on both the left and right sides in the main body 3a, and a suspension belt 8b that supports both ends of the oil injector 7 and is wound around the winder 8a.

  The oil injector 7 is provided so as to be movable within a certain range in the line direction by the position adjusting means 9. The position adjusting means 9 changes the position of the winder 8a in order to finely adjust the oil injector 7 to the center position of the boat body P1 of the pantograph P.

  A sensor unit 10 is provided on the lower center surface of the outer frame 7 a of the oil injector 7. The sensor unit 10 includes an imaging sensor that captures an image below the oil injector 7 and a distance sensor such as an ultrasonic sensor. The image data captured by the sensor unit 10 is received by the premises controller 11 to recognize the boat body P1 of the pantograph P and its relative position in the course direction. The distance data from the distance sensor is received by the premises controller 11 and the distance from the hull P1 to the sensor 10 is grasped.

  The premises controller 11 controls the oil applicator 3 to move it from the maintenance area 2a to the position corresponding to the pantograph of the train by the number of pantographs, and causes the oil applicator 3 to perform the oil injection work to the boat body P1 at the pantograph corresponding position. . That is, as shown in FIG. 6, train arrival information is acquired in advance from a train information system or the like, and the oil applicator 3 is suspended from the pantograph P with respect to the traveling roller 5 based on the arrangement information of the pantograph P of the stopped train. Control is performed so as to be arranged at the corresponding position on the down line 2. When the premises controller 11 captures the hull P1 of the pantograph P by the imaging sensor, the premises controller 11 determines whether it is the 1 hull system or the 2 hull system by pattern recognition. Further, the premises controller 11 controls the position adjusting means 9 so that the oil injector 7 is arranged at the center position in the course direction of the boat body P1. The premises controller 11 controls the elevating means 8 so as to lower the oil injector 7 to the oil injection position and raise the oil injector 7 to the original position. Further, the premises controller 11 controls the oil injector 7 so as to spray a predetermined amount of oil.

  When the oil applicator 3 in the maintenance area 2a is to perform an oiling operation, the oil applicator 3 is controlled by the wireless control signal from the local controller 11 as follows. First, by starting the traveling roller 5, the oil applicator 3 travels along the suspension line 2 toward the pantograph-corresponding position, and images are sequentially captured from the imaging sensor of the sensor unit 10, and the data of the pantograph P is obtained from the data. The boat body P1 is recognized, and the traveling roller 5 is stopped. Next, by operating the position adjusting means 9, the oil injector 7 is moved to the center position in the track direction of the boat body P1. By recognizing the boat body P1 from the image data obtained by the image sensor of the sensor unit 10, when there are two boat bodies P1, the oil injectors 7 are arranged at the center positions of the boat bodies P1, respectively. When there is one body P1, the two oil injectors 7 are arranged at the center position of the boat body P1. Next, by starting up the elevating means 8, the oil injector 7 is lowered to an oil injection position of a predetermined distance near the trolley line T while measuring the distance to the boat body P1 with the distance sensor of the sensor unit 10. By starting the oil injector 7 at the oil injection position, a predetermined amount of oil is sprayed onto the hull P1. Next, the position adjusting means 9 and the lifting / lowering means 8 are operated to return the oil injector 7 to the original position. The oil applicator 3 remains on the suspension line 2 and waits until the next control signal is received. Thereafter, the arrangement of the oil applicator 3 and the oiling operation to the boat body P1 are repeated in sequence from the premises controller 11 based on the pantograph position information of the following train. After repeating a predetermined number of times according to the remaining amount of oil in the tank 6, the premises controller 11 activates the running roller 5 to move the oil applicator 3 along the suspension line 2 to the maintenance area 2 a, Perform necessary maintenance such as oil replenishment to No. 6.

  In addition, when the train organization is uniform like the Shinkansen, and the number of pantographs, the position, and the number of hulls are fixed, the oil applicator 3 is placed in the corresponding position in advance. Since the oiling operation can be performed in the same manner by fine adjustment of the movement of the oil applicator 3 in the train traveling direction, the significant movement of the oil applicator in the train direction can be omitted.

  Since the boat body P1 coated with oil contacts the trolley wire T that is displaced zigzag in the lateral direction as the train progresses, the trolley wire T moves relative to the upper surface of the boat body P1 in the lateral direction, making the oil efficient. The oil is applied to the trolley wire T for a long distance. In addition, a large amount of oil is present in the contact area when the train starts to wear out on the trolley wire T, so that the wear can be efficiently reduced.

  The present invention can be used, for example, to automatically supply oil to a pantograph hull in a station where the trolley wire is heavily worn.
