Abstract

The invention relates to a four-head gantry welding machine for a crane beam and a control method. The four-head gantry welding machine comprises a walking frame. The top of the walking frame is provided with a beam body. The walking frame is provided with a controller. The beam body is vertically and symmetrically provided with two stand columns. The bottoms of the stand columns are provided with filament submerged arc welding machine heads controlled by the controller. The walking frame is symmetrically provided with two gas shielded welding gun machine heads controlled by the controller. According to the four-head gantry welding machine, through the two symmetrically arranged filament submerged arc welding machine heads and the two symmetrically arranged gas shielded welding gun machine heads, two welding seams between H-shaped steel on the crane beam and two side cover plates on the two sides and two welding seams between a U-shaped groove below the crane beam and the side cover plates are welded at the same time, so that four welding seams in the two sides of the crane beam are welded at the same time, and the problems that the welding stress is large, and deformation is larger after the crane beam is integrally welded when single-side welding is conducted are solved.

Description

Technical field [0001] The present invention involves the field of welding machines and specifically involves a four -headed dragon gate welding machine and control method for driving single beams. Background technique [0002] In recent years, with the globalization of industries, it has made full use of machinery and equipment and saving human resources. It has become an efficient way of working. The application of cranes can effectively save human resources and have high work efficiency. [0003] Driving is a crane, which is a large -scale workpiece. It is generally used in the lifting equipment of material cranes over factory workshops, warehouses and ingredients.It is usually welded by a variety of metal frames. Therefore, the quality of the welding quality directly affects the use of driving single beams. The driving single beam specifically refers to the main beam of the car's heavy machine. [0004] At present, most of the domestic welding of driving single beams still us...
