The application relates to the technical field of building steel beam assembling,
welding and straightening integrated machines, in particular to a building steel beam assembling,
welding and straightening integrated
machine, which comprises an assembling mechanism for splicing H-shaped steel, a conveying mechanism for conveying the spliced H-shaped steel and a
welding mechanism, the assembling mechanism comprises a plurality of supporting bases, a conveying wheel
assembly arranged on the supporting bases and a
rotating disc connected with the conveying wheel
assembly, the
rotating disc is provided with a placing opening, the
rotating disc is internally provided with a hollow cavity, and the hollow cavity is internally provided with two moving plates; the T-shaped steel and the wing plate are stably spliced, the spliced H-shaped steel is stably placed at the conveying mechanism along with the rotation of the rotating disc, the splicing mechanism can be synchronously separated from the outer side of the spliced H-shaped steel, and the phenomenon that the spliced H-shaped steel deviates when placed at the conveying mechanism due to the asynchronous separation of the clamping mechanism is effectively solved.
