Description

Technical Field

[0001] This utility model relates to the field of welding equipment technology, specifically to a U-rib gantry welding machine based on submerged arc welding. Background Technology

[0002] In steel structure engineering, especially bridge construction, the welding of U-ribs is a crucial step. Submerged arc welding (SAW), as an important welding technology, is widely used in U-rib welding. With the continuous development of engineering construction and the increasing demands for quality, the importance of U-rib gantry welding machines based on SAW is becoming increasingly prominent. U-rib structures have certain unique characteristics, requiring extremely high precision and stability in their welding. SAW can provide deep penetration and good weld quality, meeting the high standards required for U-rib welding. The U-rib gantry welding machine adopts a gantry structure, enabling stable support and precise welding operations for the U-ribs. It can adapt to U-ribs of different specifications, and through advanced control systems and adjustment devices, it ensures accurate parameters during the welding process. During welding, the machine can achieve high welding speeds and continuous operation, greatly improving welding efficiency and meeting the needs of large-scale engineering construction.

[0003] In traditional welding operations, many conventional equipment often have functional limitations. For example, the feeding and receiving pipes on traditional equipment only have a single feeding or receiving function. This leads to the need to frequently switch between different functional equipment to complete each step in the actual production process. This not only increases the complexity and time cost of operation, but may also affect the overall production efficiency and continuity due to equipment switching. Moreover, this single-function design makes the production process less smooth and unable to meet the increasingly diverse and complex welding needs. When faced with situations that require continuous multi-step collaborative operations such as feeding, welding, and receiving, it becomes inadequate and difficult to complete the task efficiently.

[0025] The rotation of the rotating component determines the contact between the receiving port 502 and the feeding port 503 and the material inlet, thereby changing the feeding and receiving paths.
