Description

Technical Field

[0001] The present invention relates to the technical field of steel structure welding, and specifically to an adjustment device and method for butt welding of steel structures. Background Art

[0002] A steel structure is a structural form composed of steel components through connection methods such as welding, bolt connection, or riveting, with steel as the main material. It is widely used in fields such as buildings, bridges, industrial plants, high-rise buildings, stadiums, towers, and offshore platforms; A patent with the publication number CN118204606B discloses an adjustment device and method for butt welding of steel structures. By starting the lead screw in the support frame, the rotation of the lead screw will drive the connecting rod on the circumferential surface of the lead screw, and then the connecting rod will drive the limiting ring to move downward to fix and limit the steel pipe. While the lead screw is rotating, it will drive the first gear at the top to rotate, and the rotation of the first gear will drive the first belt to transmit power. At this time, it will drive the first gear on the other support frame to rotate. By fixedly connecting a motor to the bottom of the lead screw of one of the support frames and then driving the two limiting rings to fix and limit the two steel pipes, the effect of convenience and speed is achieved; The above solution still has some problems in actual application. Although the steel pipe can be fixed by the limiting ring, there is no mechanism to detect whether the steel pipes are accurately butted. The limitation only ensures that the steel pipes will not move during the welding process, but it cannot determine whether the ends of the steel pipes are completely aligned. If the steel pipes are not accurately butted, it will not only cause defects in the welding between the steel pipes, such as lack of fusion, undercut, or insufficient weld strength, thus affecting the stability and safety of the entire steel structure, but also the staff can only rely on manual visual inspection or manual measurement to judge whether the steel pipes are accurately butted, which is prone to misjudgment due to human factors (such as visual errors and inaccurate measurement), and it is difficult to ensure the accuracy of the steel pipe butt joint.

[0003] Therefore, the present invention proposes an adjustment device and method for butt welding of steel structures to solve the above problems. Summary of the Invention

[0012] A steel structure butt welding adjustment method includes the following steps: Step 1: Inspect the steel pipe to be welded and the welding equipment, and remove impurities on the surface of the steel pipe; Step 2: Place the cleaned steel pipe above the fixed seat, and perform limiting after preliminary alignment; Step 3: Then adjust the positions of the steel pipes on both sides as a whole, confirm that the welding joints of the steel pipes are aligned, and fix the steel pipes above the fixed seat; Step 4: Set welding parameters, start the welding equipment for welding, and monitor the welding process in real time; Step 5: Perform appearance inspection and non-destructive testing on the weld after welding.

[0015] (III) Beneficial effects Compared with the prior art, the present invention provides a steel structure butt welding adjustment device and method, which have the following beneficial effects: Through the provided steel pipe alignment detection mechanism, the rollers can be driven to roll along the outer surfaces of two steel pipe bodies. When the ends of the steel pipe bodies are not aligned, the positions of the two rollers will change, driving the balance plate to tilt, thereby realizing the detection of the alignment degree of the ends of the steel pipe bodies. This not only eliminates the need for manual visual inspection or manual measurement, greatly reducing misjudgments caused by human factors (such as visual errors and inaccurate measurements), improving the accuracy and reliability of the detection, but also enables better fusion during the welding process of the precisely aligned steel pipe bodies, reducing the occurrence of welding defects, enhancing the strength and durability of the weld, and further strengthening the stability and safety of the entire steel structure. Moreover, it can quickly detect the alignment situation after the steel pipe bodies are placed, allowing the staff to quickly adjust according to the detection results, reducing the time for manual repeated inspection and adjustment, and improving the adjustment efficiency of the steel pipe bodies.

[0016] Through the provided second spring and extension column, the rollers can be automatically pushed to fit onto the outer surface of the steel pipe body. This not only can automatically adapt to steel pipe bodies of different diameters, ensuring good contact in different situations, improving the overall versatility and flexibility, but also can automatically push the two side rollers to be misaligned when the steel pipe bodies are not aligned, thus more accurately reflecting the position change of the ends of the steel pipe bodies, and improving the detection accuracy. Among them, through the provided clamping column and vertical plate, the positions of the rollers and the balance plate can be limited, preventing the rollers and the balance plate from approaching the port of the steel pipe body and affecting the subsequent welding. This not only leaves enough space for the welding operation, ensuring that the welding equipment can move freely to complete the welding task, but also can prevent the rollers and the balance plate from being affected by flying welding slag or high temperature during the welding process, thereby protecting the integrity of the detection device and extending its service life.

[0017] Through the provided welding path pre-treatment mechanism, during the process of detecting the alignment of the ends of the steel pipe bodies, the surface of the welding joint at the ends of the steel pipe bodies can be wiped reciprocally. This not only can effectively remove rust, oil stains, and dust impurities on the surface, preventing impurities from remaining on the welding surface and causing welding defects such as pores, lack of fusion, and slag inclusions, thereby improving the strength and durability of the weld, but also wiping during the alignment detection process can combine multiple steps into a continuous operation process, reducing the operation time and improving the construction efficiency.

[0018] By setting the brush on the balance plate, the brush can change synchronously according to the position of the balance plate, fitting onto the surface of the steel pipe body or separating from the surface of the steel pipe body. This not only can make the brush fit onto the surfaces of steel pipe bodies of different sizes, ensuring the accuracy of the wiping action, but also the contact or separation action of the brush with the surface of the steel pipe body is synchronized, improving the coherence and efficiency of the operation, and reducing the time delay caused by manual adjustment.

Specific embodiments

[0021] Next, the technical solutions of the present invention will be clearly and completely described in conjunction with the embodiments. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0022] A steel structure butt welding adjustment device of this embodiment, such as Figure 1 - Figure 7As shown in the figure, it includes a welding table 1. Fixed seats 2 are symmetrically and fixedly connected to the upper end face of the welding table 1. Steel pipe bodies 3 are placed above the fixed seats 2. It also includes a steel pipe alignment detection mechanism and a welding path preprocessing mechanism. The steel pipe alignment detection mechanism includes symmetrically arranged rings 401. Annular grooves 403 are provided on both sides of the ring 401. Support frames 402 are provided on both sides of the ring 401. The support frames 402 are fixedly connected to the upper end face of the welding table 1. And the ring 401 is rotationally connected between the two support frames 402 through the annular grooves 403. Annular racks 404 are fixedly connected to the outer surface of the ring 401. The annular racks 404 are all meshed with transmission gears 407. A driving shaft 405 is fixedly connected through between the two transmission gears 407. Support plates 408 are rotationally connected to the outer surface of the driving shaft 405. The support plates 408 are fixedly connected to the upper end face of the welding table 1. One end of the driving shaft 405 is fixedly connected with a first driving motor 406. The first driving motor 406 is fixedly connected to the side wall of one of the support plates 408. Hollow columns 411 are fixedly connected through the inner walls of the rings 401. Connecting blocks 409 are arranged at the ends of the hollow columns 411 away from the rings 401. Rollers 410 are rotationally connected to the sides of the connecting blocks 409 away from the hollow columns 411. A balance plate 413 is arranged between the two connecting blocks 409. The steel pipe alignment detection mechanism is used to detect the positions of the steel pipe bodies 3 on both sides during the butt joint process.

[0023] In this embodiment, as Figure 4 and Figure 6 shown, extension columns 412 are slidably connected through the sides of the hollow columns 411 close to the connecting blocks 409. Second springs 427 are fixedly connected between the extension columns 412 and the interiors of the hollow columns 411. The extension columns 412 are fixedly connected to the connecting blocks 409 at the ends away from the hollow columns 411. When the extension columns 412 are driven to slide out of the hollow columns 411, the extension columns 412 will push the connecting blocks 409 to move synchronously, driving the rollers 410 inside the connecting blocks 409 to fit onto the outer surface of the steel pipe body 3.

[0024] In this embodiment, as Figure 3 and Figure 4 shown, side plates 414 are symmetrically and fixedly connected to the sides of the connecting blocks 409 close to the balance plate 413. Through grooves 415 are provided on one of the side plates 414. Sliders 416 are slidably connected in the through grooves 415. A connecting column 417 is fixedly connected through between the two sliders 416. One end of the balance plate 413 is rotationally connected to the connecting column 417. The other end of the balance plate 413 is rotationally connected between the two side plates 414. When the balance plate 413 tilts, since one end of the balance plate 413 is rotationally connected between the two side plates 414, the balance plate 413 will pull the connecting column 417 to which the other end is rotationally connected to drive the sliders 416 to slide synchronously in the through grooves 415.

[0025] In this embodiment, as Figure 3 shown, buttons 418 are fixedly connected to the inner walls of the through grooves 415 on the side away from the sliders 416. The buttons 418 are electrically connected to alarms 419, and the alarms 419 are fixedly connected to the side walls of the side plates 414. When the sliders 416 slide in the through grooves 415, the buttons 418 will be pressed. Through the electrical connection between the buttons 418 and the alarms 419, the alarms 419 can be turned on to work, reminding the staff that the balance plate 413 is tilted.

[0026] In this embodiment, as Figure 4 and Figure 5 shown, sliding grooves 423 are symmetrically formed on the upper end surface of the balance plate 413. Sliding plates 424 are slidably connected in the sliding grooves 423. First springs 426 are fixedly connected between the sliding plates 424 and the sliding grooves 423. Dial plates 425 are fixedly connected to the side walls of the sliding plates 424. Columns 422 are fixedly connected to the sides of the sliding plates 424 away from the springs. Vertical plates 421 are sleeved on the outer surfaces of the columns 422. The columns 422 are slidably connected through the vertical plates 421. A cross plate 420 is fixedly connected between the upper ends of the two vertical plates 421. The cross plate 420 is fixedly connected between the two hollow columns 411. By driving the columns 422 to be inserted into the vertical plates 421, the distance between the balance plate 413 and the cross plate 420 can be shortened, and the position of the balance plate 413 can be fixed.

[0027] In the prior art, although the steel pipe can be fixed by the limiting ring, no mechanism is provided to detect whether the steel pipes are accurately butted. The limitation only ensures that the steel pipes will not move during the welding process, but it cannot determine whether the ends of the steel pipes are completely aligned. If the steel pipes are not accurately butted, it will not only cause defects in the welding between the steel pipes, such as lack of fusion, undercut or insufficient weld strength, thus affecting the stability and safety of the entire steel structure, but also the staff can only rely on manual visual inspection or manual measurement to judge whether the steel pipes are accurately butted, which is prone to misjudgment due to human factors (such as visual errors and inaccurate measurement), and it is difficult to ensure the accuracy of the steel pipe butt joint. Compared with the prior art, the rollers 410 can be driven to roll along the outer surfaces of the two steel pipe bodies 3. When the ends of the steel pipe bodies 3 are not aligned, the positions of the two rollers 410 will change, driving the balance plate 413 to tilt, so as to detect the alignment degree of the ends of the steel pipe bodies 3. This not only eliminates the need for manual visual inspection or manual measurement, greatly reducing misjudgment caused by human factors (such as visual errors and inaccurate measurement), improving the accuracy and reliability of the detection, but also the accurately aligned steel pipe bodies 3 can be better fused during the welding process, reducing the occurrence of welding defects, improving the strength and durability of the weld, and further enhancing the stability and safety of the entire steel structure. Moreover, it can quickly detect the alignment situation after the steel pipe bodies 3 are placed, and the staff can quickly adjust according to the detection results, reducing the time for manual repeated inspection and adjustment, and improving the adjustment efficiency of the steel pipe bodies 3.

[0028] On other levels, this embodiment also provides a welding path preprocessing mechanism for cleaning the welding path of the steel pipe body 3 synchronously during the process of detecting the butt joint position of the steel pipe body 3, as Figure 4 and Figure 7 shown. The welding path preprocessing mechanism includes a cross 502. A brush 503 is fixedly connected to the lower end surface of the cross 502. Moving plates 504 are symmetrically and fixedly connected to the upper end surface of the cross 502. The moving plates 504 are all horizontally slidably connected to the lower end surface of the balance plate 413.

[0029] In this embodiment, as Figure 7 shown, a groove 508 is formed on the upper end surface of the cross 502. A sliding column 507 is slidably connected in the groove 508. A connecting plate 506 is fixedly connected to the upper end of the sliding column 507. A rotating shaft 505 is fixedly connected to the side of the upper end of the connecting plate 506 away from the sliding column 507. The upper end of the rotating shaft 505 penetrates and is rotatably connected to the balance plate 413. A second driving motor 501 is fixedly connected to the upper end of the rotating shaft 505. The second driving motor 501 is fixedly connected to the upper end surface of the balance plate 413. When the second driving motor 501 is turned on to drive the rotating shaft 505 to rotate, the rotating shaft 505 can drive the sliding column 507 to reciprocate in the groove 508 through the connecting plate 506, so that the sliding column 507 can push and pull the cross 502 to move horizontally back and forth.

[0030] Compared with the prior art, during the alignment detection of the end of the steel pipe body 3, the surface of the welded joint at the end of the steel pipe body 3 can be wiped reciprocally at the same time. This can not only effectively remove rust, oil stains and dust impurities on the surface, avoiding the situation that impurities remain on the welding surface and cause welding defects such as pores, lack of fusion and slag inclusions, thereby improving the strength and durability of the weld, but also during the alignment detection process, wiping can combine multiple steps into a continuous operation process, reducing the operation time and improving the construction efficiency.

[0031] At other levels, this embodiment also provides a method for adjusting the butt welding of steel structures, as Figure 1 - Figure 7 shown, including the following steps: Step 1: Inspect the steel pipe to be welded and the welding equipment, and remove impurities on the surface of the steel pipe; Step 2: Place the cleaned steel pipe above the fixed seat 2 and limit it after preliminary alignment; Step 3: Then adjust the positions of the steel pipes on both sides as a whole, confirm the alignment of the welded joints of the steel pipes, and fix the steel pipes above the fixed seat 2; Step 4: Set welding parameters, start the welding equipment for welding, and monitor the welding process in real time; Step 5: Conduct appearance inspection and non-destructive testing on the weld after welding.

[0032] In this embodiment, in step 3, after the alignment of the welded joints of the steel pipes, a steel pipe alignment detection mechanism is used to check the alignment of the ends of the steel pipes.

[0033] In this embodiment, in step 4, during the real-time monitoring of the steel pipe welding process, welding parameters and monitoring data are recorded, and the parameters and monitoring data during the welding process are analyzed.

[0034] The working process and principle involved in the overall content of the above embodiment are as follows: When the staff needs to weld the steel pipe body 3, first place the two steel pipe bodies 3 above the fixed seat 2, so that the ends of the two steel pipe bodies 3 are close to each other, and at the same time slide into the inside of the ring 401. Then, push the ends of the two steel pipe bodies 3 to be aligned with each other. After confirming that the alignment of the steel pipe body 3 is completed, the staff can move the two side plates 425 closer to each other, drive the slide plate 424 to slide in the chute 423 opened on the upper end surface of the balance plate 413, squeeze the first spring 426 connected between the slide plate 424 and the chute 423, and at the same time drive the column 422 connected to the side away from the chute 423 of the slide plate 424 to move horizontally synchronously, so that the column 422 slides out of the side plate 414. After the column 422 is separated from the side plate 414, due to the rebounding force of the second spring 427 connected between the extension column 412 and the hollow column 411, the extension column 412 can be automatically pushed out of the hollow column 411, so that the connecting block 409 connected to the end of the extension column 412 away from the hollow column 411 moves away from the hollow column 411, and drives the roller 410 rotatably connected in the connecting block 409 to fit on the outer surface of the steel pipe body 3, so that it can automatically adapt to steel pipe bodies 3 of different diameters, ensure good contact under different conditions, and improve the overall versatility and flexibility; During the movement of the connecting block 409, since side plates 414 are symmetrically connected to the side walls of the connecting block 409, through slots 415 are formed in the side plates 414, sliders 416 are slidably connected in the through slots 415, and the sliders 416 are rotatably connected to the balance plate 413 through connecting columns 417. Therefore, the connecting block 409 will drive the balance plate 413 to descend synchronously through the side plates 414, sliders 416 and connecting columns 417. After the rollers 410 are attached to the outer surface of the steel pipe body 3, the staff can turn on the first driving motor 406 to drive the driving shaft 405 to rotate, so that the two transmission gears 407 connected to the outer surface of the driving shaft 405 rotate synchronously. At this time, since the transmission gears 407 are meshed with the annular rack 404 and the ring 401, during the rotation of the transmission gears 407, the transmission gears 407 will push the annular rack 404 to drive the ring 401 to rotate between the two support frames 402. As the ring 401 rotates, the ring 401 will drive the rollers 410 to roll along the outer surface of the steel pipe body 3 through the hollow column 411, the extension column 412 and the connecting block 409. When a deviation is found in the alignment of the ends of the two steel pipe bodies 3, due to the elastic force of the second spring 427 connected between the inside of the extension column 412 and the hollow column 411, the attachment between the rollers 410 and the outer surface of the steel pipe body 3 will be maintained. At this time, the two rollers 410 on both sides will also deviate synchronously with the position of the steel pipe body 3. When one of the rollers 410 deviates, the roller 410 will drive the side plate 414 to move synchronously through the connecting block 409. At this time, the side plate 414 will pull one end of the balance plate 413 to move. When one end of the balance plate 413 is stressed, the balance plate 413 will tilt. During the tilting process of the balance plate 413, the balance plate 413 will pull the slider 416 to slide in the through slot 415 towards the button 418 through the connecting column 417, press the button 418, and turn on the alarm 419 connected to the side wall of the side plate 414 to work, reminding the staff that the end of the steel pipe body 3 is offset, realizing the detection of the alignment degree of the end of the steel pipe body 3. It not only eliminates the need for manual visual inspection or manual measurement, greatly reduces misjudgment caused by human factors (such as visual errors and inaccurate measurement), improves the accuracy and reliability of detection, but also enables better fusion during the welding process of the accurately aligned steel pipe body 3, reduces the occurrence of welding defects, improves the strength and durability of the weld, and further enhances the stability and safety of the entire steel structure. Moreover, it can quickly detect the alignment situation after the steel pipe body 3 is placed, and the staff can quickly adjust according to the detection results, reducing the time for manual repeated inspection and adjustment, and improving the adjustment efficiency of the steel pipe body 3; During the process of the balance plate 413 synchronously descending and approaching the steel pipe body 3, the balance plate 413 will drive the brush 503 to fit onto the surface of the steel pipe body 3 through the moving plate 504 and the cross 502, so that the brush 503 can fit onto the surfaces of steel pipe bodies 3 of different sizes, ensuring the accuracy of the wiping action. After the brush 503 fits onto the surface of the steel pipe body 3, as the operator turns on the first drive motor 406, during the rotation of the ring 401 driven by the drive shaft 405, the transmission gear 407 and the annular rack 404, the operator can synchronously turn on the second drive motor 501 to drive the rotating shaft 505 to rotate, and the connecting plate 506 connected to the lower end of the rotating shaft 505 is used to toggle the sliding column 507 to move synchronously around the rotating shaft 505 as the center, so that the sliding column 507 reciprocates in the groove 508 opened at the upper end of the cross 502. As the sliding column 507 moves, since the moving plates 504 are symmetrically connected to the upper end of the cross 502 and the moving plates 504 are slidably connected to the lower end surface of the balance plate 413, the sliding column 507 will toggle the cross 502 to reciprocate on the lower end surface of the balance plate 413 through the groove 508, driving the brush 503 connected to the cross 502 to reciprocally wipe the end surface of the steel pipe body 3. This can not only effectively remove rust, oil stains and dust impurities on the surface, avoid impurities remaining on the welding surface and causing welding defects such as pores, lack of fusion and slag inclusions, thereby improving the strength and durability of the weld, but also perform wiping during the alignment detection process, combining multiple steps into a continuous operation process, reducing the operation time and improving the construction efficiency; After the alignment detection of the end of the steel pipe body 3 is completed, the staff can simultaneously turn off the first drive motor 406 and the second drive motor 501, and then move the dial plates 425 closer to each other again, driving the slide plate 424 to slide in the chute 423 and squeezing the first spring 426 in the chute 423. When the slide plate 424 cannot move, the staff can lift the dial plate 425 upward, pulling the balance plate 413 to rise through the slide plate 424. During the rising process of the balance plate 413, the balance plate 413 can drive the two side connecting blocks 409 to rise synchronously through the connecting column 417, the slider 416, the through groove 415 and the side plate 414, pushing the extension column 412 connected to the upper end of the connecting block 409 to slide into the hollow column 411, squeezing the second spring 427 inside the hollow column 411, and at the same time pulling the roller 410 rotatably connected inside the connecting block 409 away from the outer surface of the steel pipe body 3. When the extension column 412 cannot rise anymore, the staff can keep the height of the dial plate 425 and at the same time release the dial plate 425. Through the rebound force of the first spring 426, it can push the slide plate 424 to slide reversely in the chute 423, and at the same time drive the clamping column 422 connected to the side wall of the slide plate 424 to be clamped onto the vertical plate 421, thereby limiting and fixing the heights of the balance plate 413 and the roller 410. This not only leaves enough space for welding operations, ensures that the welding equipment can move freely to complete the welding task, but also prevents the roller 410 and the balance plate 413 from being affected by splashing welding slag or high temperature during the welding process, thus protecting the integrity of the detection device and extending its service life.
