Abstract

The invention is applicable to the technical field of bridge construction equipment and provides a mounting operation platform for a cantilever of a steel box girder. The mounting operation platform comprises a moving system, a top frame, a vertical frame, an operation platform and a counterweight assembly. The moving system comprises vertical casters. The top frame is located above the cantilever of the steel box girder, the operation platform is located on the lower portion of the cantilever of the steel box girder, and the vertical frame is located on the side of the cantilever of the steel box girder. The top of the vertical frame is fixedly connected with the top frame, and the bottom of the vertical frame is fixedly connected with the operation platform. The vertical casters are mounted at the bottom of the top frame and abut against the top face of the cantilever of the steel box girder, and the counterweight assembly is disposed on the top frame. The mounting operation platform for the cantilever of the steel box girder is convenient to manufacture and mount and low in labor cost. The whole mounting operation platform can be pushed to move only through labor operation, and accordingly the requirement of construction of the cantilever of the steel box girder of a whole bridge is met.

Description

technical field [0001] The invention belongs to the technical field of bridge construction equipment, and in particular relates to a steel box girder cantilever installation operation platform. Background technique [0002] Overpasses and viaducts in urban roads use a large number of integral steel box girders with large cantilever arms on both sides. The cantilever part is installed separately during bridge construction. After the cantilever is hoisted, except for the longitudinal joints and transverse joints of the top plate, which can be welded on the bridge deck, the remaining cantilever webs, lower flanges, cantilever longitudinal rib inserts, The installation, welding, and final paint repair work of the decorative panels of the cantilever insert section and the cantilever arc decorative panels need to be carried out under the cantilever. [0003] Aiming at the needs of a series of beam bottom assembly, welding and painting operations involved in the installation of th...
