The invention discloses a cover plate device of an upper manhole, and belongs to the technical field of architectural engineering construction. The cover plate is used for solving the problems that an existing cover plate of the upper manhole is complex in structure and high in cost. The cover plate device of the upper manhole comprises a pair of tracks and a cover plate, wherein the tracks are symmetrically arranged on the upper manhole, and the cover plate can slide along the tracks. The tracks are formed by welding steel channels and steel angles, the two right-angle side ends of each steel angle are located in a groove in the corresponding steel channel, and external corners of the steel angles are away from the grooves. According to the cover plate device of the upper manhole, the external corners of the steel angles on the tracks are in clamp fit with an annular groove of a pulley, so that the cover plate is prevented from swinging left and right in the sliding process, and the limiting ...
