Outdoor escalator of pedestrian overpass

The invention discloses an escalator of a pedestrian overpass, and relates to the technical field of escalator cleaning equipment. The escalator comprises an escalator body and hand straps, wherein the bottoms of soft rubber blocks are fixedly connected with cleaning plates, the bottom ends of the cleaning plates are rotatably connected with contact balls, and the bottom ends of connecting rods are fixedly connected with the top of a scraper; and a plurality of elastic pressing plates are arranged in the two ends of the scraper. According to the outdoor escalator, the cleaning plates and the upper surfaces of grooves are used for friction, and the contact balls reduce the contact area, so that blockage caused by snow block accumulation is prevented; and friction force and vibration balls at the bottom end are used for enabling the cleaning plates to generate a vibration effect, a scraping part and the inner walls of the grooves are mutually rubbed, arc-shaped plates rotate through friction force, and the scra
