Among lifting machinery, U-beams are widely used in the main beam structure of cranes and hoists. The cross-sectional shape of the U-beam is U-shaped. Such a structural design makes the U-beam have higher strength and rigidity, and can withstand large loads and resist deformation. As a common structural beam, the U-beam plays an important role in lifting machinery, construction and engineering fields. Its unique U-shaped cross-section and reasonable design make it have high strength, good load-bearing capacity and stability.

[0055] In addition, referring to Figures 1-8, the present invention provides a method for assembling structural parts for port machinery, comprising the following steps:

[0056] S1: Clean and polish the panels that have been cut and measured to prepare for subsequent assembly;

[0057] S2: Start the equipment through the control machine 4, and adjust the positions of the internal clamping mechanism 5, the external welding structure 10, and the limiting mechanism 12 according to the expected data through the control machine 4 to prepare the equipment before assembly;

[0058] S3: Place the bottom splicing plate on the conveying roller 2, then start the external driving mechanism 8 through the control machine 4 to drive the conveying roller 2 to rotate, thereby driving the bottom splicing plate into the equipment until it contacts the limit hydraulic plate 1205 to stop, then adjust the position of the external extrusion wheel 707 by rotating the adjustment hand wheel 708, and move the external extrusion wheel 707 to contact the side of the bottom splicing plate, and then adjust the position of the bottom splicing plate by adjusting the external extrusion wheel 707, so that the bottom splicing plate is aligned on the central axis of the equipment;

[0059] S4: Then, the height of the internal pressing mechanism 5 is adjusted by the control machine 4 according to the expected data, and the pressing roller 606 is pressed against the upper surface of the bottom splicing plate. Then, the prepared side splicing plate is vertically fed into the device, and the internal transmission wheel 604 is started to rotate by the control machine 4. Driven by the internal transmission wheel 604, the side plates on both sides overcome the pressure of the torsion spring shaft assembly 602 to squeeze the internal transmission wheel 604, and move toward the inside of the device while maintaining verticality with the bottom splicing plate under the squeezing of the internal transmission wheel 604 and the external squeezing rod 706, until it contacts the limit hydraulic plate 1205 and stops;

[0060] S5: At this time, the initial splicing and shaping of the U-shaped beam has been completed through the cooperation of the internal pressing mechanism 5, the internal driving mechanism 6, and the external extrusion mechanism 7. Then the staff detects the side plate of the U-shaped beam through the measuring equipment, and fine-tunes the position of the external extrusion wheel 707 by adjusting the hand wheel 708 to adjust the curvature of the side plate;

[0061] S6: After completing the measurement and correction work, the control machine 4 controls the external welding structure 10 and the internal welding mechanism 11 to drive the external welder 1008 and the internal welder 1108 to contact the inner and outer joints of the U-shaped beam. After completing the preparation work for welding, the control machine 4 raises the limit hydraulic plate 1205, starts the external welder 1008 and the internal welder 1108 to weld the inner and outer surfaces of the U-shaped beam at the same time, and starts the internal drive servo motor 605 and the external drive servo motor 804 to drive the U-shaped beam to move to the left while welding. When the U-shaped beam is spliced, it is moved out of the equipment and sent to the next process. The control machine 4 can control the moving speed and welding distance of the U-shaped beam.
