The invention discloses a trolley hanging beam multifunctional structure of a shipbuilding gantry crane, wherein a bearing bulge is arranged on the middle side wall of each connecting arm II; the two connecting arms II are connected and fixed with each other in a clamping way by the bearing bulges through a fixed ring II; two connecting rings are connected with each other by a fixed ring I. According to the trolley hanging beam multifunctional structure of the shipbuilding gantry crane, when both of two pin shafts are arranged at the position of a center bearing seat, the two connecting rings are connected with each other by the fixed ring I, the two connecting arms II are connected with each other by the fixed ring II, and connection limit is carried out at two points, so that two lifting mechanisms which are respectively arranged under the two pin shafts are maintained to be stable to a certain extent, two parts of lifting appliances arranged at the lower part can vertically droop side by side, the phenomenon that the trouble of a manufacturer is increased due to rotation can be avoided, and risk for lifting is avoided.
