[0002] Steel structures are engineering structures composed of components made of steel profiles and steel plates, which are connected by welding, riveting, or bolting. They have advantages such as high strength, light weight, fast construction speed, and good seismic performance, and are widely used in engineering fields such as buildings, bridges, towers, and industrial plants.

[0003] In the processing and manufacturing of steel structural components, assembly and welding are critical processes, and their quality directly determines the structural strength and service life of the final component. Currently, steel structure welding is mostly completed using welding equipment. Before welding, two steel plates are usually welded together to form a "T" shape. After this part is welded, another steel plate is placed on the "T" shaped steel structure, and finally welded into an I-beam. However, this step-by-step welding method requires multiple operations to complete the assembly of the I-beam, which not only increases the number of welding steps but also extends the processing cycle. Summary of the Invention

[0016] The embodiments of this application are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this application, and should not be construed as limiting this application.

[0017] The steel structure welding apparatus of this application embodiment will now be described with reference to the accompanying drawings.

[0018] like Figures 1-4 As shown, the steel structure welding device of this application embodiment may include a support drive mechanism 1, and a side plate conveying mechanism 2, a middle plate conveying assembly 3, a side plate limiting assembly 4 and a welding mechanism 5 installed on the support drive mechanism 1.

[0019] It should be noted that a flipping machine (not shown in the figure) is installed at the unloading end of the welding device to achieve the flipping of the steel structure after welding on one side, thereby enabling the welding of the other side of the steel structure.

[0020] The side plate conveying mechanism 2 may include an inclined assembly 21 and a conveying roller 22.

[0021] It should be noted that the side plate conveying mechanism 2 described in the above embodiment is provided in two sets, thereby realizing the synchronous conveying of the plates on both sides of the steel structure.

[0022] It should be noted that the conveying roller 22 described in the above embodiment is driven by a geared motor (not shown in the figure) to realize the conveying process of the plate.

[0023] The tilting component 21 is mounted on the support drive mechanism 1, and the conveying roller 22 is rotatably mounted on the tilting component 21.

[0024] Understandably, the installation of the conveyor roller 22 is completed under the action of the tilting component 21. Then the conveyor roller 22 completes the support and conveying of the steel plate. After that, under the action of the tilting component 21, the plate is tilted and slides onto the side plate limiting component 4 for support.

[0025] Specifically, such as Figures 1-3 As shown, the tilting assembly 21 may include a hydraulic rod 211, a mounting frame 212, a mounting plate 213, a support rod 214, and a hinge frame 215.

[0026] Hydraulic rod 211 and support rod 214 are respectively mounted on support drive mechanism 1, and mounting plate 213 is mounted on mounting frame 212. Mounting plate 213 is hinged to the extended end of hydraulic rod 211 and support rod 214 respectively through hinge frame 215.

[0027] Specifically, under the action of hydraulic rod 211 and support rod 214, the support of conveying roller 22 is completed by mounting frame 212, mounting plate 213 and hinge frame 215. Then, under the action of hydraulic rod 211, one side of conveying roller 22 is lifted by mounting frame 212, mounting plate 213 and hinge frame 215. Then, support rod 214 completes the limiting of conveying roller 22 by mounting frame 212, mounting plate 213 and hinge frame 215, thereby tilting conveying roller 22 and the plate on conveying roller 22 and slowly sliding it onto side plate limiting assembly 4, thereby realizing the verticalization of plate and facilitating subsequent welding of steel plate.

[0028] The medium plate conveying assembly 3 may include a hydraulic cylinder 31, a fixed frame 32, and a drive roller 33.

[0029] It should be noted that the hydraulic cylinder 31 described in the above embodiment is provided in two sets, thereby completing the support of the fixed frame 32 and the transmission roller 33, and completing the adjustment of the position of the middle plate during the splicing process.

[0030] It should be noted that the transmission roller 33 described in the above embodiments is driven by a geared motor (not shown in the figure).

[0031] Hydraulic cylinder 31 is mounted on support drive mechanism 1, and transmission roller 33 is mounted on the extended end of hydraulic cylinder 31 via fixed frame 32.

[0032] Understandably, the fixed frame 32 supports the transmission roller 33, and then the hydraulic cylinder 31 adjusts the height of the fixed frame 32 and the transmission roller 33 while the fixed frame 32 is installed on the support drive mechanism 1, thereby ensuring that the steel plate on the transmission roller 33 is in the middle of the two steel plates.

[0033] The side plate limiting assembly 4 is mounted on the support drive mechanism 1. The side plate limiting assembly 4 may include a connecting frame 41, an abutment roller 42, an auxiliary plate 43, and an abutment wheel 44.

[0034] It should be noted that the connecting frame 41 described in the above embodiment is provided with a clearance groove, so that when the hydraulic rod 211 and the support rod 214 move, the support rod 214 can slide, thereby realizing the erection and fixation of the plate that slides onto the abutment roller 42.

[0035] The connecting frame 41 is mounted on the support drive mechanism 1, the abutting roller 42 is rotatably mounted on the connecting frame 41, and the abutting wheel 44 is rotatably mounted on the connecting frame 41 via the auxiliary plate 43.

[0036] Understandably, the installation of the abutment roller 42 is completed under the action of the connecting frame 41. The plate then slowly slides onto the abutment roller 42 and stands upright under the inclination of the conveyor roller 22, and contacts the abutment wheel 44 on the auxiliary plate 43. Subsequently, the plate is pressed and fixed on the abutment roller 42 by the compression of the conveyor roller 22 and the abutment wheel 44, which facilitates the welding of the plate on the transmission roller 33 and the plate on the abutment roller 42. After welding, the rotation of the conveyor roller 22 and the transmission roller 33 transports the welded steel structure from the abutment roller 42. At the same time, the abutment wheel 44 completes the abutment of the plate while avoiding affecting the transportation of the steel structure.

[0037] The above-described method enables the one-time assembly and forming of I-beams without the need for step-by-step operations, which reduces welding processes and significantly shortens the processing cycle.

[0038] In one embodiment of this application, such as Figure 1 As shown, the support drive mechanism 1 may include a base plate 11 and a drive assembly 12.

[0039] It should be noted that the drive assembly 12 described in the above embodiment is provided in two sets, so as to synchronously drive the side plate conveying mechanism 2 installed on the drive assembly 12.

[0040] The drive assembly 12 is mounted on the base plate 11.

[0041] Furthermore, such as Figure 1 As shown, the drive assembly 12 may include a bracket 121, a sliding frame 122, and a lead screw 123.

[0042] It should be noted that the lead screw 123 described in the above embodiment is driven by a drive motor (not shown in the figure), and both ends of the lead screw 123 are provided with oppositely shaped threaded grooves on their outer sides, thereby realizing the opposite transmission of the two sets of sliding frames 122.

[0043] The bracket 121 is mounted on the base plate 11, the lead screw 123 is rotatably mounted on the bracket 121, the sliding frame 122 is threaded onto the lead screw 123, and the sliding frame 122 is slidably connected to the base plate 11.

[0044] Understandably, the screw 123 is installed under the action of the bracket 121, and then the sliding frame 122 is driven by the rotation of the screw 123. The movement of the sliding frame 122 drives the conveying mechanism 2 of the two side plates, thereby achieving the effect of squeezing and fixing the steel plate.

[0045] In one embodiment of this application, such as Figure 4 As shown, the welding mechanism 5 may include a transmission assembly 51, a connecting rod 52, and a welder 53.

[0046] It should be noted that the welding device 53 described in the above embodiments is prior art, so it will not be described in detail here.

[0047] As one possible scenario, a cylinder can be installed between the connecting rod 52 and the transmission assembly 51 to adjust the height of the connecting rod 52 and the welder 53, thereby avoiding obstruction of the steel plates when they are erected.

[0048] It should be noted that the welding mechanism 5 described in the above embodiment is provided in two sets, so as to simultaneously complete the synchronous welding process on both sides of the spliced ​​steel structure.

[0049] The transmission assembly 51 is mounted on the base plate 11, the connecting rod 52 is mounted on the transmission assembly 51, and the welder 53 is mounted on the connecting rod 52.

[0050] Understandably, the welding device 53 is installed under the action of the connecting rod 52, and then the connecting rod 52 and the welding device 53 are driven by the transmission component 51, thereby realizing the welding treatment of the joint of the spliced ​​steel plates.

[0051] Furthermore, such as Figure 4 As shown, the transmission assembly 51 may include a fixed plate 511, a lead screw 512, and a sliding plate 513.

[0052] It should be noted that the lead screw 512 described in the above embodiments is driven by a transmission motor (not shown in the figure).

[0053] The fixed plate 511 is mounted on the base plate 11, the lead screw 512 is rotatably mounted on the fixed plate 511, and the sliding plate 513 is threaded onto the lead screw 512, and the sliding plate 513 is slidably connected to the base plate 11.

[0054] Specifically, the installation of the fixed plate 511 is completed under the action of the transmission component 51, and then the fixed plate 511 completes the installation of the lead screw 512. After the steel plate splicing is completed, the lead screw 512 rotates and drives the sliding plate 513, the connecting rod 52 and the welder 53 to slide on the lead screw 512. Then, under the action of the welder 53, the welding treatment of the spliced ​​steel plate joint is realized.

[0055] Specifically, the steel structure welding device provided in this application can be used for one-time assembly and welding of I-beams. In actual operation, personnel place the two side plates horizontally on the conveying rollers 22 of the left and right side plate conveying mechanisms 2, and place the middle plate horizontally on the drive rollers 33 of the middle plate conveying assembly 3. At this time, the conveying rollers 22 on both sides and the drive roller 33 in the middle are all on the same horizontal plane, which facilitates subsequent alignment.

[0056] Subsequently, the hydraulic cylinder 31 of the middle plate conveying assembly 3 is activated, and its extended end pushes the fixing frame 32 upward, driving the transmission roller 33 to rise, so that the upper surface of the middle plate is at the same height as the side plate to be welded (i.e., the side of the side plate) after it is erected, ensuring that the weld seam is aligned. Next, the hydraulic rod 211 of the tilting assembly 21 is activated, and its extended end pushes the hinge frame 215 upward, pushing one side of the mounting plate 213 and the mounting frame 212 to rotate upward around the hinge point of the support rod 214. The mounting frame 212 drives the conveying roller 22 to tilt, so that the side plate on the conveying roller 22 slowly slides down the roller surface due to gravity. During the descent, the bottom of the side plate first contacts the abutment roller 42 of the side plate limiting assembly 4, and continues to slide down until it is fully erected under the rolling support of the abutment roller 42; at the same time, the upper part of the side plate contacts the abutment wheel 44 on the auxiliary plate 43, and the abutment wheel 44 abuts the side plate from the outside (the side away from the middle plate) to prevent it from tilting outward. At this point, the side plate is vertically clamped between the abutment roller 42 and the abutment wheel 44, completing the vertical positioning.

[0057] Re-starting the drive assembly 12, the lead screw 123 continues to rotate, driving the sliding frames 122 on both sides to move further towards the center. Since the side plates are vertically limited by the abutment rollers 42 and abutment wheels 44, the movement of the sliding frames 122 drives the entire side plate conveying mechanism 2 to press against the middle plate through the tilting assembly 21, so that the inner side surfaces of the upright side plates are tightly fitted to the left and right sides of the middle plate, forming a complete "I"-shaped assembly structure. At this time, the abutment wheels 44, supported by the auxiliary plate 43, can roll with the lateral movement of the side plates without obstructing the side plate feeding.

[0058] Then, the welding mechanism 5 is activated, and the drive motor drives the lead screw 512 to rotate, driving the sliding plate 513 to move longitudinally along the fixed plate 511. The sliding plate 513 drives the connecting rod 52 and the welder 53 to move along the weld direction. Since there is a welding mechanism 5 on each side, the two sets of welders 53 can simultaneously weld the two longitudinal butt joints between the middle plate and the left and right side plates. The welding head is aligned with the weld, achieving uniform and continuous welding.

[0059] After welding, the hydraulic rod 211 retracts, resetting the tilting component 21 and restoring the conveying roller 22 to a horizontal state. Simultaneously, the hydraulic cylinder 31 retracts, lowering the transmission roller 33 to its initial height. The lead screw 123 of the drive component 12 rotates in the opposite direction, moving the sliding frames 122 on both sides and the side plate conveying mechanism 2 outward, causing the welded I-beam to disengage from the abutting roller 42 and abutting wheel 44 of the side plate limiting component 4. Finally, the conveying roller 22 and the transmission roller 33 rotate in opposite directions under the drive of their respective reduction motors, feeding the formed I-beam backward (or forward) to the next process (such as flipping it to weld the other side or unloading). Throughout the process, the conveying, erection, lateral positioning, middle plate height adjustment, three-plate bonding, synchronous welding, and finished product output of the side plates are completed continuously and automatically without manual intervention or step-by-step operation, significantly improving the welding efficiency of the I-beams and shortening the processing cycle.

[0060] In summary, the steel structure welding device of this application embodiment can realize the one-time assembly and forming of I-beams without the need for step-by-step operation, which reduces the welding process and significantly shortens the processing cycle.
