Prefabricated bridges are gradually emerging as an efficient way of bridge construction. In prefabricated bridges, the welding quality of nodes is directly related to the safety and durability of the entire bridge structure. In the construction of prefabricated viaducts on urban expressways, nodes need to withstand frequent vehicle loads and complex environmental factors.

The number of auxiliary material cylinder racks 502 in a single area is adjusted according to the need to lift the auxiliary materials. Accessories and driving parts are provided at both ends of the auxiliary material cylinder rack 502.

[0044] The accessories are used to cooperate with the sliding connection between the slide 501 and the auxiliary material cylinder frame 502, and the driving member is used to drive the auxiliary material cylinder frame 502 to move along the surface of the slide 501.

Multiple groups of adapter plates 601 are arranged on the top of the lifting and matching frame 6, and a lifting cylinder frame 602 that penetrates the driving slot and is connected to the driving cylinder is arranged at the bottom of the adapter plate 601. It should be noted that micro motors are arranged inside the multiple groups of sliders for driving the multiple groups of sliders to move inside the corresponding long slots.

[0047] The lifting and matching frame 6 is started, and the lifting cylinder frame 602 is driven by the driving cylinder to slide axially along the driving groove, thereby driving the adapter plate 601 to approach the bottom of the scattered components. The lifting cylinder frame 602 drives the adapter plate 601 to slide upward, lifting the group of scattered components and moving them upward. With the cooperation of the welding machine 304, the scattered components are welded and fixed to the rough weldments.

[0049] If the defect data is greater than the preset welding comparison data, it is determined that there is a defect in the welding of the area, and a defect signal is generated. The database sends the welding signal to the single controller of the welding equipment through the main control room. After receiving the defect signal, the single controller immediately generates a text message in the style of "weld sequence 0383 / weld point abnormality / spray color mark / data record" and displays it on the display screen of the single controller, and emits a "beep beep" alarm sound for 5 seconds to alert the control personnel;

[0050] After receiving the defect signal, the single controller immediately controls the operation of the material pump 307. The material pump 307 is connected to the external pigment container pipeline through a pipeline, and extracts a certain amount of pigment and transports it to the spray pipe 308. A marking rotary cylinder part is provided on the top of the spray pipe 308 and is sleeved on the rod body of the outer wall of the top of the welding machine 304. The marking rotary cylinder part drives the spray pipe 308 to rotate, and the welding area that generates the defect signal is sprayed and marked accordingly, so that the semi-finished weldment can enter the subsequent steps for screening and secondary repair by relevant personnel.

[0051] In combination with Example 1, Example 2 and Example 3, it can be known that the present invention realizes the rapid and orderly loading and transportation of steel structure parts through the coordination of prefabrication processing, conveying mechanism and main and auxiliary material transport frame 5, significantly improves production efficiency, and the coordination of automated welding equipment and adaptive fixtures ensures the stability and accuracy of the welding process. At the same time, the flexible adjustment of components such as the welding coordination frame 3 and the adjustment beam 303 enables the welding machine 304 to accurately weld parts of different shapes and sizes.

[0052] The cooperation between the auxiliary material transport rack 5 and the lifting and matching rack 6 ensures the integrity and structural strength of the weldment; in addition, the real-time detection of the ultrasonic sensor and the processing of the single controller can timely detect welding defects and spray mark them, which is convenient for subsequent screening and repair, ensuring the welding quality.
