The invention relates to a pedestrian crossing reversible line-marking vehicle which mainly comprises a vehicle body, wherein rectangular grooves are formed in the upper end of the vehicle body and arranged in the for-and-aft direction; a working frame is slidably mounted inside each rectangular groove in the length direction; a motor is mounted at the right end of each working frame; a ball screw and a polished rod are mounted inside each working frame in the length direction; each ball screw is connected with the corresponding motor; a mounting frame is slidably mounted on each ball screw and slidably connected with the corresponding polished rod; each motor is fixedly mounted at the lower end of the corresponding mounting frame; a painting device is connected with each motor; a swinging column is hinged to the left end of each rectangular groove; a base plate is arranged at the left end of the vehicle body; the swinging columns are all mounted on the right end surface of the base plate in a hinged manner; the rear end of the base plate is hinged to the vehicle body; a swinging air cylinder is arranged at the front end of the base plate. The pedestrian crossing reversible line-marking vehicle is simple to use and convenient to operate, and can be used for marking a pedestrian crossing, namely a zebra crossing, with not only lines which are rectangular and perpendicular to a roadway extending track, but also lines which are parallelogram-shaped and not perpendicular to the roadway extending track.
