Tower or silo frame section pairing method and pairing platform

Abstract

A group method for a tower or a tubular holder set provides a method that a plurality of tower portions are positioned on a rotary roller holder and a lifting supporting group car on a track, and the axis of the tower portions is positioned on a horizontal direction or a better butting direction via adjusting the rotary roller holder and the supporting group car, another tower portion needed to weld with the tower portion is hold by a moving-tubular swing-arm group car, or with the lifting supporting group car, or with the rotary roller holder together, and then the tower portion is moved to another along the track with adjusting the space between them and the arm lifting or the arm moving of the moving-tubular swing-arm car to match the tower portion and the tower axis together and group weld seams. The invention has advantages of not only small working space and low intensity of labor, but also safety, highly effective, keeping work pieces non-broken, and good quality of grouping.

Description

technical field [0001] The present invention relates to the grouping and pairing of cylindrical or conical tower (tube) frame steel cylinders with a single section length of 1-4 meters, diameter of 2-6 meters, thickness of 10-70 mm, and height of 10-35 meters. The final welding is mainly used in the assembly method and assembly platform of the tower (tube) frame section in the field of wind power tower tower, offshore drilling platform pile leg, high-rise building column and so on. Background technique [0002] Now for the pairing and spot welding of large cylindrical or conical steel cylinders with a single length of 1-4 meters, a diameter of 2-6 meters, a thickness of 10-70 mm, and a height of 10-35 meters, such as wind turbine towers Group pairing and spot welding, there are rolling group pairing and spot welding methods, that is, put the tower that needs to be butt welded on the ground, use lifting equipment to move one section to the other butt joint, so that the corres...

AI Technical Summary

Problems solved by technology

In addition to the above two pairing methods, for large-scale tower (tube) frame sections, no new pairing method has been proposed, and there is no other pairing equipment, and the quality of the finished product of the welded steel cylinder The key to efficiency and efficiency lies in the assembly of steel cylinders. Therefore, it is urgent to find a method and platform for assembly with a small footprint, low labor intensity, safety and efficiency, no damage to the workpiece, and high-quality assembly welds.
