The invention discloses an anti-seismic structure of a bridge frame of a bridge crane. The anti-seismic structure comprises an end part support frame, bearing frames and load beams, wherein the two load beams are respectively erected above the end support frame, the end part support frame is connected with the load beams together by the bearing frames, the lateral surface, far from the center of each load beam, of each bearing frame is a trapezoidal inclined surface, the trapezoidal inclined surface is of an acute angle relative to the horizontal direction, and two surfaces on two sides of the trapezoidal inclined surface are parallelogram inclined surfaces. According to the anti-seismic structure of the bridge frame of the bridge crane, the structure that the overall gravity center of each bearing frame inclines to the center of the bearing capacity of the crane is adopted, and when the inclined bearing frame is subjected to a seism or the bearing capacity of the crane is suddenly increased, the load beams and the bearing frames on two sides of the crane are unlikely to break, so that the crane is safe to use; and the anti-seismic structure is simple and novel in design, and is a novel powerful structure of the crane bridge.
