Abstract
PURPOSE: To return the current collecting shoe separated from a trolley wire to the original position in a pantograph by detecting the separated shoe between the pantograph and the trolley wire, when once separated, and lifting the shoe for predetermined time to thereby increase the follow-up ability of the shoe.
CONSTITUTION: The contacting strength between a trolley wire 16 and a current collecting shoe 17 is detected by a poppet 24. When the shoe 17 approaches separation from the wire 16, the poppet 24 detects it to thereby supply hydraulic oil to a cylinder 19 of a shoe lifting unit during time determined by the discharging time of an accumulator 29 so as to lift a piston 23 telescoped with the cylinder 19. It excessively compresses a recoil spring 15 at a distance corresponding to the stroke of the piston 23 by means of the reaction of the piston lifted so as to increase the lifting strength of the shoe 17. Thus, the separated shoe 17 is returned to its original position so as to prevent an arc from occurring therebetween.
