The invention provides a foldable overhauling platform for a communication antenna of a power and communication shared iron tower and belongs to the technical field of power and communication engineering. The foldable overhauling platform for the communication antenna of the power and communication shared iron tower comprises a platform body, wherein the platform body comprises a first platform assembly and a second platform assembly; the first platform assembly and the second platform assembly are arranged on angle steel of the iron tower in an axial symmetry manner; the first platform assembly and the second platform assembly are connected through a hinge; each of the first platform assembly and the second platform assembly comprises a grid plate I and a grid plate II; and the grid plateI is connected with the grid plate II through a hinge. By adopting the foldable overhauling platform provided by the invention, a standing working platform is provided when overhauling workers of communication department overhaul the communication antenna on the shared iron tower; and meanwhile, a phenomenon that nests are prone to be built on a fixed platform by birds so that power overhauling workers cannot get up to the tower is avoided.
