Because of the complexity of the concrete pump truck base structure, the X base is always the structural member with the worst manufacturability and the greatest welding difficulty of the concrete pump truck. The X base structure also becomes a bottleneck for comprehensively implementing automatic welding of the structural members of the concrete pump truck.
At present, the X base of the concrete pump truck is of a single-body structure, the production line is a welding production line suitable for the single-body X base, and the production line is only single superposition of the same working station. The single X base is of a single composite box structure, the structure is complex, and the number of internal welding seams is large. During manufacturing, reasonable welding assembly sequence arrangement is required according to the operability and convenience of welding; meanwhile, the welding deformation of each link is strictly controlled, and the welding quality is ensured.
The single-body type X base is manufactured by adopting a multi-time splice point assembly and multi-time welding step-by-step splice welding mode, so that the splice welding process is more and the sequence requirement is strict, and the automatic welding is difficult to realize. On one hand, because more internal welding seams and short welding seams exist, more welding joints are needed to be subjected to repeated manual repair welding, and the automatic welding rate is low; on the other hand, the step-by-step welding mode of the single-body type X base leads to the fact that the welding arm of the robot stretches into the box body and the outside, the length of the welding arm of the robot and the stroke of an outer shaft are required to be longest, the design difficulty and the cost of equipment are increased, meanwhile, due to the fact that the structure is limited, the welding arm of the robot and a workpiece are more in interference, and the automatic welding rate is low.
