Abstract

The invention provides a steel box girder total assembly jig frame girder transporting channel movable cross beam and a using method thereof. The using method comprises the steps that S1, a movable base plate is assembled; S2, a movable cross beam splicing step; S3, a steel box girder assembly is manufactured; S4, the movable cross beam is disassembled and rotated, and the steel box girder is transported away for assembly; and S5, the step S2 to the step S4 are repeated to finish the production of the total assembly of the plurality of steel box girders. The steel box girder total assembly jig frame girder transporting channel movable cross beam is manufactured by a simple tool, is simple to operate, is convenient and easy to implement, and has high applicability; unsafe accidents and the like caused by falling of the movable cross beam due to manual dismounting of the movable cross beam are avoided; labor and machinery are saved, and the construction task is efficiently completed.

Description

technical field [0001] The invention belongs to the technical field of steel box girder manufacturing, and in particular relates to a movable crossbeam of a steel box girder assembly tire frame transporting beam channel and a use method thereof. Background technique [0002] The steel box girder assembly frame is the key tool to ensure the manufacturing accuracy of the steel box girder. At present, steel box girder tires are usually transported by two hydraulic beam transport flat cars. In order to ensure that the beam transport flat car enters and exits, jacks up, drops the beam, and walks, etc. Active beams. Under the prior art, the traditional movable beam adopts high-strength bolts at both ends to detachably connect with the total tire frame. After the assembly of the steel box girder is completed, a small forklift is needed to support the movable beam, and the splicing plates on both sides of the movable beam are manually removed, and then the movable beam is moved to...
