Technical Field
[0001] The present invention belongs to the technical field of steel structure welding, and in particular relates to an integral welding system for assembled steel structure nodes. Background Art
[0002] In the field of engineering construction, corrugated web H-shaped steel is a new type of high-efficiency profile. The corrugated web H-shaped steel is composed of a corrugated web and upper and lower flange plates welded together. The welding nodes of the corrugated web are mainly concentrated in the connection between the crest and trough and the flange plates, as well as the longitudinal butt joints of the corrugated web. The welding quality of these nodes directly determines the shear resistance and fatigue life of the structure.
[0003] For example, the Chinese patent document (CN102773642A) discloses an online conveying device and automatic welding equipment for corrugated web H-shaped steel. The automatic welding equipment consists of a support frame, a cable drag chain, a drive mechanism, a workbench, a welding machine, and a control system. The welding machine and the controller are respectively installed on the workbench surface. The bottom surface of the workbench is connected to the top surface of the support frame by a drive mechanism. The workbench carries the welding machine and the controller on the table, and is driven by the drive mechanism to run on the top surface of the support frame. At the same time, the photoelectric sensor transmits its photoelectric scanning signal to the controller, and the controller transmits the processed control signal to the welding machine. The welding gun of the welding machine is controlled to perform online precise welding on the interface between the corrugated web and the flange plate of the online corrugated web H-shaped steel. However, during the use of the equipment, the scanning accuracy of its photoelectric sensor may be affected by the spatter, light, and smoke generated during the welding process, resulting in an impact on the welding node accuracy of the weld between the corrugated web and the flange plate. Therefore, improvement is needed. Summary of the Invention

[0058] 2. In the present invention, by setting up a wire feeding adaptation component, when the roller is at the trough, the first vertical plate will transport the liquid inside the auxiliary liquid bag to the inside of the main liquid bag, causing the main liquid bag to expand and drive the rectangular slider, connecting rod and wear-resistant block to move, thereby increasing the wire feeding resistance of the driving unit inside the wire feeding unit, and then automatically and appropriately reducing the wire feeding speed of the trough. The real-time and local speed control effectively reduces the unstable state of the molten pool caused by the change of the geometric shape in the node area, and significantly improves the welding penetration consistency, weld formation quality and joint reliability in the node area.
[0059] 3. In the present invention, by setting up a parallel adjustment component, the linear moving unit synchronously drives the movable extrusion unit to move in opposite directions, so that the horizontal plate drives the second vertical plate, the rectangular plate, the fixed rod and the fixed block to move. By presetting or adjusting the relative position of the limit slide in the oblique section inside the stroke groove in real time, the end point of the motion trajectory of the fixed block can be dynamically changed, so that the entire system can accurately and conveniently set the optimal wave peak reset posture for corrugated webs of different thicknesses and different waveforms, thereby effectively improving the applicability of the system during use.

[0095] Specific implementation method: first install the active conveying unit to the side of the welding body 1 away from the inside of the auxiliary conveying unit 2, first place the flange plate horizontally on the active conveying unit, and then install the corrugated web vertically to the top center of the flange plate. The active conveying unit will convey the installed flange plate and corrugated web to the top pressure unit 13, the auxiliary conveying unit 2, the mobile extrusion unit 5 and the limiting pressure roller 12 in sequence. During this process, the limiting pressure roller 12 will directly press on the top surface of the flange plate to provide sufficient downward pressure, and cooperate with the top pressure unit 13 to tightly install the corrugated web on the flange plate to ensure the welding interface fitting effect of the flange plate and the corrugated web, and the mobile extrusion unit 5 will assist in ensuring the central conveying effect of the corrugated web on the flange plate. In the above comprehensive configuration When the corrugated web and the flange plate are transported to the telescopic welding gun head 9, the roller 603 will roll close to the surface of the corrugated web. When the roller 603 moves from the trough to the crest of the corrugated web, the roller 603 drives the guide rod 602 and the sliding block 605 to move inside the installation box 601 under the action of the corrugated web, and the sliding block 605 drives the rack 609 to move through the rack 609. The linkage effect between the rack 609 and the gear 610 is used to transmit power to the gear 610, so that the gear 610 drives the connecting shaft 611, the fixed shaft 612, the mounting sleeve 613 and the telescopic welding gun head. 9 is rotated to adjust the use angle of the telescopic welding gun head 9, so that the telescopic welding gun head 9 contacts the weld position of the corrugated web and the flange plate in a vertical manner, ensuring that the welding process is always in the best process state, ensuring the fusion quality of the weld root node, and significantly and comprehensively improving the welding quality of the entire weld from the lowest point of the trough to the highest point of the peak, making it more uniform and more reliable. During this process, the first vertical plate 608 will drive the limiting slide bar to move inside the travel groove 616. As the limiting slide bar continues to move and under the cooperation of the oblique section inside the travel groove 616, when the roller 603 moves to the peak of the corrugated web, the oblique section inside the travel groove 616 will cause the limiting slide bar to drive the first vertical plate 608 and the rack 60 9 moves in the direction away from the gear 610, and under the cooperation of the torsion spring, the connecting shaft 611, the fixed shaft 612 and the mounting sleeve 613 are reset, even if the telescopic welding gun head 9 contacts the crest of the corrugated web at a vertical angle, so that the welding arc can optimally act on the root node of the weld, greatly improving the fusion quality and structural integrity of the joint root, and making the penetration depth on the entire weld highly uniform, so that the system can obtain the best welding process state. As the corrugated web moves, when the roller 603 moves from the crest of the corrugated web to the trough, the first spring 604 will drive the sliding block 605, the first vertical plate 608 and the rack 609 to reset, and during the movement of the limit slide bar inside the travel groove 616,The second spring 607 will drive the first vertical plate 608 and the rack 609 to move in the direction of the gear 610 and mesh with the gear 610, and the first vertical plate 608 will drive the gear 610 to rotate in the opposite direction through the rack 609, so that the telescopic welding gun head 9 contacts the welding position at the trough in a vertical direction with the wave crest. In summary, this system can automatically adjust the use angle of the telescopic welding gun head 9 according to the use surface of the corrugated web, so that the telescopic welding gun head 9 is always perpendicular to the entire welding node surface of the corrugated web and the flange plate, significantly and comprehensively improving the welding quality of the entire weld seam of the corrugated web and the flange plate.

[0115] The mounting frame 3 slides on the outer peripheral side of the connecting box 4, and a third through hole for sliding connection of the connecting frame 614 is opened on one side of the mounting frame 3. A hydraulic cylinder is fixedly connected to the external top side of the mounting frame 3, and one end of the hydraulic cylinder output shaft is fixedly connected to the top of the connecting box 4.
[0116] Specific implementation method: According to actual needs, the linear moving units on both sides are started at the same time, and the linear moving units are used to synchronously drive the mobile extrusion units 5 to move in opposite directions, so that the two mobile extrusion units 5 can limit and fix the corrugated webs of different thicknesses. During this process, the mobile extrusion unit 5 will drive the second vertical plate 805 and the rectangular plate 803 to move through the horizontal plate 806, so that the rectangular plate 803 drives the fixed rod 804 and the fixed block 615 to move in the direction of the rectangular frame 801. The use position of the limiting slide bar relative to the internal oblique section of the stroke groove 616 can be adjusted to adjust the reset vertical angle of the wave crest, so that the system is suitable for the welding requirements of corrugated webs of different thicknesses, thereby effectively improving the applicability of the system during use.
[0117] Working principle: When in use, first install the active conveying unit to the side of the welding body 1 away from the inside of the auxiliary conveying unit 2, first place the flange plate horizontally on the active conveying unit, and then install the corrugated web vertically to the top center of the flange plate. The active conveying unit will convey the installed flange plate and corrugated web to the top pressure unit 13, the auxiliary conveying unit 2, the mobile extrusion unit 5 and the limiting pressure roller 12 in sequence. During this process, the limiting pressure roller 12 will directly press on the top surface of the flange plate to provide sufficient downward pressure, and cooperate with the top pressure unit 13 to tightly install the corrugated web on the flange plate to ensure the welding interface fitting effect of the flange plate and the corrugated web, while the mobile extrusion unit 5 will assist in ensuring the central conveying effect of the corrugated web on the flange plate;
[0118] When the corrugated web and flange plate are conveyed to the telescopic welding gun head 9, the roller 603 will roll closely against the surface of the corrugated web. When the roller 603 moves from the trough to the crest of the corrugated web, the roller 603 drives the guide rod 602 and the sliding block 605 to move inside the installation box 601 under the action of the corrugated web, and the sliding block 605 drives the rack 609 to move through the rack 609. The linkage effect between the rack 609 and the gear 610 is utilized to transmit power to the gear 610, so that the gear 610 drives the connecting shaft 611, the fixed shaft 612, the mounting sleeve 613 and the telescopic welding gun head 9 to rotate, and the use angle of the telescopic welding gun head 9 is adjusted so that the telescopic welding gun head 9 contacts the weld position of the corrugated web and flange plate in a vertical manner.
[0119] During this process, the first vertical plate 608 will drive the limiting slide bar to move inside the travel groove 616. As the limiting slide bar continues to move and under the cooperation of the internal oblique section of the travel groove 616, when the roller 603 moves to the crest of the corrugated web, the internal oblique section of the travel groove 616 will cause the limiting slide bar to drive the first vertical plate 608 and the rack 609 to move away from the gear 610. Under the cooperation of the torsion spring, the connecting shaft 611, the fixed shaft 612 and the mounting sleeve 613 are reset, even if the telescopic welding gun head 9 contacts the crest of the corrugated web at a vertical angle. As the corrugated web moves, when the roller 603 moves from the crest of the corrugated web to the trough, the first spring 604 drives the sliding block 605, the first vertical plate 608 and the rack 609 to reset, and when the limit slide bar moves inside the travel groove 616, the second spring 607 drives the first vertical plate 608 and the rack 609 to move in the direction of the gear 610 and mesh with the gear 610, and the first vertical plate 608 drives the gear 610 to rotate in the opposite direction through the rack 609, so that the telescopic welding gun head 9 contacts the welding position at the crest to the trough in a vertical direction;
[0120] When the roller 603 is at the trough, that is, when the second spring 607 drives the first vertical plate 608 and the rack 609 to engage with the gear 610, the first vertical plate 608 will squeeze the auxiliary liquid capsule 709, and the liquid inside the auxiliary liquid capsule 709 will be transported to the main liquid capsule through the infusion tube 708, so that the main liquid capsule will expand and drive the rectangular slider 703, the connecting rod 704 and the wear-resistant block 705 to move, so that the wear-resistant block 705 contacts the outer surface of the friction roller 706, so as to increase the wire feeding resistance of the internal drive unit of the wire feeding unit 11, thereby appropriately reducing the wire feeding speed at the trough;
[0121] According to actual needs, the linear moving units on both sides are started at the same time, and the linear moving units synchronously drive the mobile extrusion units 5 to move in opposite directions, so that the two mobile extrusion units 5 can limit and fix the corrugated webs of different thicknesses. During this process, the mobile extrusion unit 5 will drive the second vertical plate 805 and the rectangular plate 803 to move through the horizontal plate 806, so that the rectangular plate 803 drives the fixed rod 804 and the fixed block 615 to move in the direction of the rectangular frame 801, and adjust the use position of the limit slide relative to the internal oblique section of the stroke groove 616, so that the system is suitable for the welding requirements of corrugated webs of different thicknesses.
