Movable storing platform used for storing steel truss girder truss pieces

The utility model relates to a movable storing platform used for storing steel truss girder truss pieces, and belongs to the technical field of bridge constructing equipment. The movable storing platform comprises multiple main beams which are arranged parallelly. An integral platform framework is formed by connecting of the ends of the main beams through outer parallel connection, and connecting of middles through inner parallel connection. The bottom of the platform framework is slidably connected with a track of a pre-jointing platform by arranging moving idler wheels and limiting steel plates. The middle two main beams are provided with vertical supporting frames used for fixing the upper portions of the steel truss girder truss pieces. The other main beams are provided with jointing buttresses which are symmetric in a left and right mode and used for fixing the lower portion of the steel truss girder truss piece. The side faces of the two main beams which are arranged on the outer sides are provided with traction anchorage plates. According to the movable storing platform used for storing the steel truss girder truss pieces, the steel truss girder truss pieces are firstly jointed, and is transported through the movable storing platform in an integral mode, so that the times of transporting and lifting are reduced, the construction cost is greatly saved, and the high economic efficiency is achieved.
