Abstract

PURPOSE: To permit the rapid quenching of the slider of the third truck current collector, as built in a train, by irradiation of lasers onto the sliding face of the slider.
CONSTITUTION: A train 14 equipped with the third truck current collector whose slider 15 has worn sliding face 15a in the subway, etc., is sent onto a pit line 1. And, a light-focusing lens mirror 19 is focalized on the sliding face 15a, and then lasers from a lasers generator are irradiated onto the sliding face 15a of the slider 15 through the second mirror 16, a light-focusing lens 17, and an object lens 18 for quenching by heating. At the same time, the light-focusing lens mirror 19 is slowly moved rockingly and quenching is made while moving the focus in a zigzag manner along a light path A. Thus, the sliding face 15a of the slider 15, as attached to the train 14, can be quenched again.
