The invention discloses a walking beam assembly technology. The walking beam assembly technology comprises the following specific steps that (1) a fixed support and an adjusting support are arranged on a molding bed, the opening degrees of the supports are measured to meet requirements, the upper end and the lower end of the adjustment support are each provided with a margin of 20 mm, and integrated marking, trimming and cutting are conducted; (2) the adjustment support, the fixed support and bases are sequentially assembled and welded through flange weld joints; (3) a moving support, a lifting frame, a jacking oil cylinder and a moving beam are sequentially assembled, connection pin shafts are assembled, the moving support is fixed through spot welding, welding is completed, and pipe joint supports and a transverse movement oil cylinder are assembled; (4) the walking beam is transferred to a sand wash workshop for overall sand wash, and primer coating is conducted; (5) other parts andauxiliary components are assembled. The walking beam assembly technology has the advantages that the walking beam assembly technology is developed for the first time in China, the fixed support and the moving support are machined in an integrated manner, the structural components are disassembled, the assembly method is simple, operation is convenient, and the structure is stable.
