It is mainly used to move various parts of the bridge to the designated location and complete the installation. The crossbeam is one of the main structures of the bridge-erecting machine. The crossbeam is mainly used to support the width of the bridge section and help distribute and bear the load. It usually spans the width of the bridge-erecting machine and contacts the bottom of the bridge section. The crossbeam is usually a solid beam made of steel or other high-strength materials and can withstand greater weight and pressure.

[0003] When manufacturing existing bridge-building machine crossbeams, multiple groups of steel are usually connected by welding to achieve the required length. During the welding process, since the bridge-building machine crossbeam is long, multiple welding processes are required, so the steel needs to be clamped and disassembled multiple times. This process not only increases the complexity and time cost of production, but also may cause stress concentration at the welding joints, thereby affecting the overall strength and stability of the beam. In addition, multiple clamping and disassembly may also cause deformation of the steel and poor welding, thereby affecting the quality and precision of the final product. Summary of the invention

This automation and precise control greatly improves welding efficiency and reduces the need for manual operation. Through the coordinated action of the dual-axis motor 92, the gear system and the magnetic device, the automatic docking and adjustment of the welding equipment are realized. When the steel 6 pushes the activation member 99, the drive device 9 will automatically move the dual-axis motor 92 to make the gear three 93 mesh with the gear one 73, thereby driving the transmission roller 72 and the conveying roller one 74 to rotate, and accurately delivering the steel 6 to the bottom of the welding torch 88. The automatic reset function of the device ensures the stable operation of the welding equipment during the welding process, and After welding is completed, the welding position can be quickly adjusted to prepare for the next welding. This automation and precise control not only improves the efficiency and consistency of the welding process, but also reduces the need for manual operation and ensures the stability of welding quality. The steel 6 in the support tube 5 can be supported to keep the steel 6 fixed during welding, avoiding welding defects caused by the movement or instability of the steel 6. The threaded groove 52 and the threaded rod 53 on the support tube 5 facilitate the precise adjustment and fixation of the steel 6, so that the equipment can adapt to steels 6 of different sizes and shapes, improving the flexibility and adaptability of operation. ;
