When the pantograph 1 is in a standby state, the pantograph is arranged on a roof in a folded shape; when the electric locomotive is opened and lifted, the pantograph 1 is opened and kept perpendicular to the road, so that the electric locomotive can still have good contact with the power supply line 2 when the electric locomotive changes lanes. Wherein, realization of the left-right movement of the pantograph 1: the pantograph 1 comprises a translation mechanism 107, an image recognition module 5 is arranged at the top of the vehicle and is specially responsible for signal acquisition and relative position calculation of an upper power supply line 2, and the rotation and movement amplitude of the translation mechanism 107 are controlled through a data processing unit 4, so that the pantograph 1 always keeps contact with the power supply line 2.
