Description

Technical Field

[0001] The present invention relates to the technical field of welding, and more specifically, to a welding device for steel beams in steel structure construction. Background Art

[0002] A steel beam is a beam made of steel. Crane beams and working platform beams in factories, floor beams in multi-story buildings, purlins in roof structures, etc. can all use steel beams. Steel beams are generally divided into section steel beams and composite beams. Section steel beams are simple to process and have a relatively low cost, but the cross-sectional dimensions of section steel are restricted by certain specifications; composite beams are welded or riveted by steel plates or section steel, and have greater flexural stiffness and torsional stiffness, and are suitable for situations where there are lateral loads, high torsional requirements, or beam height is restricted.

[0003] During the existing steel structure construction process, it is necessary to weld steel beams with R-shaped stiffeners. During the welding process of the two, they are directly welded by a welding torch. During the welding process, welding slag is likely to flow to the un-welded parts, causing welding slag adhesion, affecting the cleanliness and surface quality of the un-welded area, and further affecting the quality of subsequent welding. Therefore, we provide a welding device for steel beams in steel structure construction to solve the above problems. Summary of the Invention

[0012] As a further solution of the present invention: The auxiliary impact member includes an L-shaped block fixedly connected to the outer wall of one of the limiting plates, and one end of the L-shaped block penetrates through the outer wall of the sliding seat and is slidably connected to the sliding seat. A coupling shaft is fixedly connected to one side of each rotating shaft, and an impact block is fixedly connected to one end of the coupling shaft, and the impact block is attached to the outer wall of the L-shaped block.

[0013] Compared with the prior art, the beneficial effects of the present invention are:

[0014] 1. By setting the cooperation of parts such as the second one-way threaded lead screw, rotating the second one-way threaded lead screw, the second one-way threaded lead screw rotates to drive the connecting block to drive the suspension seat to abut against the end of the R-shaped stiffening rib, so as to press the R-shaped stiffening rib, making the part of the R-shaped stiffening rib to be welded closely adhere to the steel beam. The close fit can reduce defects such as gaps and pores during the welding process, thereby improving the welding quality.

[0015] 2. By setting the cooperation of parts such as the bidirectional threaded lead screw, after the suspension seat abuts against the R-shaped stiffening rib, the bidirectional threaded lead screw can be rotated, and the bidirectional threaded lead screw drives the two limiting plates to move towards the R-shaped stiffening rib until the two limiting plates are respectively attached to the outer wall of the R-shaped stiffening rib (here it is attachment not fixation), limiting the R-shaped stiffening rib to prevent the R-shaped stiffening rib from shaking or displacing left and right during the welding process, ensuring that it is always in the accurate welding position, which helps to ensure the welding accuracy and quality.

[0016] 3. By setting the cooperation of parts such as the pressing block, when welding treatment is required for the R-shaped stiffening rib, the welding torch can be placed on the top of the second rotating ring, and then the first one-way threaded lead screw is rotated to drive the pressing block to move downward to fix the placed welding torch. Subsequently, when the welding torch is welding, the sliding block can be pushed horizontally according to requirements to make the welding torch close to the welding part. The first rotating ring and the second rotating ring can also be rotated respectively according to requirements to adjust the angle of the welding torch, providing a stable basis for the welding operation, which helps to ensure the stability of the welding quality, avoiding problems such as uneven weld seams and insecure welding caused by the shaking of the welding torch. The operator can perform the welding operation more efficiently, reducing the time wasted on adjusting the position and angle of the welding torch, improving the work efficiency. Especially when facing welding tasks with complex structures, this flexible adjustment method can significantly improve the overall work progress.

[0017] 4. By setting the cooperation of parts such as the limit plate, the welding torch and the limit plate are arranged in a dislocation manner, and the welding head of the welding torch is higher than the limit plate. When the welding torch is in the welding process, the limit plate can block the welding slag, effectively preventing the welding slag from flowing to the un-welded parts and preventing the welding slag from adhering to these parts. Thus, the cleanliness and surface quality of the un-welded area are ensured, creating good conditions for the subsequent welding work, avoiding the influence of the existence of welding slag on the welding quality and effect, reducing the extra work of cleaning the welding slag, and further improving the quality of the subsequent welding;

[0018] 5. By setting the cooperation of parts such as the spur gear, when the welding torch needs to move downward, it can push the arc seat to drive the sliding seat to move downward through the limit plate. When the spur gear moves downward, it contacts the inclined surface on one side of the rotating tooth, pushing the rotating tooth to rotate. When the spur gear separates from the rotating tooth, the torsion spring no longer receives an external force to push the rotating tooth to reset, so that the back of the rotating tooth is limited by the baffle to limit the spur gear, enabling the staff not to continuously apply an extrusion force to the arc seat. Thus, the limit plate can move downward with the welding torch in an intermittent manner to block, thereby improving the overall stability of the device, more effectively blocking the welding slag, and improving the stability of the welding quality;

[0019] 6. By setting the cooperation of parts such as the L-shaped block, when the rotating tooth rotates away from the baffle, it drives the impact block to rotate synchronously through the coupling shaft. When the spur gear separates from the rotating tooth, the torsion spring drives the impact block to reset, so that the impact block can hit the L-shaped block, and then act on the R-shaped stiffening rib through resonance. Thus, the R-shaped stiffening rib can generate slight vibrations during the welding process. The vibrations can make the liquid metal in the welding pool flow and mix better, help the gas escape, reduce the formation of defects such as pores, make the weld more dense, and improve the welding quality.

For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the internal communication of two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific situations. The following describes the embodiments according to the overall structure of the present invention.

[0031] Please refer to Figures 1 to 8, this embodiment provides a welding device for steel beams in steel structure construction, including a steel beam 1 and an R-shaped stiffener 3 arranged inside the steel beam 1. A welding torch 6 is arranged on one side of the R-shaped stiffener 3; a pressing mechanism, located at the top of the steel beam 1, for pressing the R-shaped stiffener 3. The pressing mechanism includes a suspension seat 5. The pressing mechanism further includes a fixed seat 2 arranged on the top of the steel beam 1. One end of the fixed seat 2 is fixedly connected to a connecting seat 4. A second one-way threaded lead screw 18 is rotatably connected inside the connecting seat 4, and one end of the second one-way threaded lead screw 18 penetrates to the outside of the connecting seat 4. A connecting block 17 is threadedly connected to the outer wall of the second one-way threaded lead screw 18, and the bottom of the connecting block 17 is fixedly connected to the suspension seat 5. The connecting block 17 is slidably connected inside the connecting seat 4;

[0032] A fixing component for fixing can be installed at the bottom of the fixed seat 2, and the fixing component can be composed of components such as suction cups or clamping jaws that can form clamping and fixing. Since it is prior art, this solution is not described in detail here. First, when welding the R-shaped stiffener 3 to the steel beam 1, the R-shaped stiffener 3 can be abutted against the welding position, and then the fixed seat 2 can be fixed at the specified position through the fixing component. Subsequently, the second one-way threaded lead screw 18 can be rotated. The rotation of the second one-way threaded lead screw 18 drives the connecting block 17 to drive the suspension seat 5 to abut against the end of the R-shaped stiffener 3, thereby pressing the R-shaped stiffener 3, making the welding position of the R-shaped stiffener 3 closely attached to the steel beam 1. The tight fit can reduce defects such as gaps and pores during the welding process, thus improving the welding quality;

[0033] Please refer to Figures 2 to 6, limiting components are arranged on both sides of the suspension seat 5. The limiting components include a sliding seat 9 slidably connected to the inner side of the suspension seat 5. Two limiting plates 8 are slidably connected to the inner side of the sliding seat 9. The two limiting plates 8 are respectively attached to one side of the R-shaped stiffener 3. Support components for supporting the welding torch 6 are arranged on both sides of the limiting plate 8. The limiting components further include a bidirectional threaded screw rod 22 rotatably connected to the inner side of the sliding seat 9. External threads including a positive thread and a reverse thread are arranged on the outer wall of the bidirectional threaded screw rod 22. The two limiting plates 8 are respectively threadedly connected to the outer walls of the positive thread and the reverse thread. Limiting chutes matching the two limiting plates 8 are formed in the inner side of the sliding seat 9. The support components include sliding blocks 11 slidably connected to the outer walls of the limiting plates 8. Guide grooves matching the sliding blocks 11 are formed in the outer walls of the limiting plates 8. A first rotating ring 10 is rotatably connected to one side of the sliding block 11. One end of the first rotating ring 10 is fixedly connected to an arc-shaped seat 7. An arc-shaped block 12 is slidably connected to the inner side of the arc-shaped seat 7. A second rotating ring 13 is rotatably connected to the top of the arc-shaped block 12. The support components further include a bracket 15 fixedly connected to the top of the second rotating ring 13. A first one-way threaded screw rod 16 is rotatably connected to the inner side of the bracket 15. A pressing block 14 is threadedly connected to the outer wall of the first one-way threaded screw rod 16. The pressing block 14 is slidably connected to the inner side of the bracket 15;

[0034] After the suspension seat 5 abuts against the R-shaped stiffener 3, the bidirectional threaded screw rod 22 can be rotated. The bidirectional threaded screw rod 22 drives the two limiting plates 8 to move towards the R-shaped stiffener 3 until the two limiting plates 8 are respectively attached to the outer wall of the R-shaped stiffener 3 (here it is attachment rather than fixation), limiting the R-shaped stiffener 3 to prevent the R-shaped stiffener 3 from shaking or displacing left and right during the welding process, ensuring that it always remains in the accurate welding position, which helps to ensure the welding accuracy and quality;

[0035] When welding treatment needs to be performed on the R-shaped stiffener 3, the welding torch 6 can be placed on the top of the second rotating ring 13. Subsequently, the first one-way threaded screw rod 16 is rotated to drive the pressing block 14 to move downward to fix the placed welding torch 6. Subsequently, when the welding torch 6 is welding, the sliding block 11 can be pushed to move horizontally according to requirements, so that the welding torch 6 is close to the welding part. The first rotating ring 10 and the second rotating ring 13 can also be rotated respectively according to requirements to adjust the angle of the welding torch 6, providing a stable basis for the welding operation, which helps to ensure the stability of the welding quality, avoiding problems such as uneven weld seams and insecure welding caused by the shaking of the welding torch 6. The operator can perform the welding operation more efficiently, reducing the time wasted on adjusting the position and angle of the welding torch 6 and improving the work efficiency. Especially when facing welding tasks with complex structures, this flexible adjustment method can significantly improve the overall work progress;

[0036] The welding torch 6 and the limit plate 8 are arranged in a dislocation manner, and the welding head of the welding torch 6 is higher than the limit plate 8. During the welding process, the welding torch 6 can block the welding slag through the limit plate 8, effectively preventing the welding slag from flowing onto the un-welded parts and sticking to these parts, thus ensuring the cleanliness and surface quality of the un-welded area, creating good conditions for the subsequent welding work, avoiding the influence of the welding slag on the welding quality and effect, reducing the extra work of cleaning the welding slag, and further improving the quality of the subsequent welding.

[0037] Please refer to Figures 2 to 8 , the longitudinal mover, located inside the suspension seat 5, is used to cooperate with the limit component for operation. The longitudinal mover includes a connecting spring 19 installed between the sliding seat 9 and the suspension seat 5. One side of the sliding seat 9 is fixedly connected with a fixed shaft 26. One side of the suspension seat 5 is provided with a through groove communicating with the inside, and the through groove is matched with the fixed shaft 26. One end of the fixed shaft 26 extends to the outer wall of the through groove and is fixedly connected with a spur gear 27. One side of the suspension seat 5 is provided with a rectangular rod 20. A plurality of positioning seats 30 are fixedly connected to the inside of the rectangular rod 20. The plurality of positioning seats 30 are equidistantly distributed on one side of the rectangular rod 20. A rotating cog 28 is arranged inside each positioning seat 30, and the rotating cog 28 is meshed with the spur gear 27. One side of the rotating cog 28 is fixedly connected with a rotating shaft 31, and one end of the rotating shaft 31 penetrates to the outside of the positioning seat 30 and is rotatably connected with the positioning seat 30. A torsion spring 32 is installed between the rotating shaft 31 and the positioning seat 30. A plurality of baffles 29 are fixedly connected to the inside of the rectangular rod 20. Each baffle 29 is correspondingly attached to the inside of a rotating cog 28. An auxiliary impact member is arranged between the rotating shaft 31 and one of the limit plates 8. A T-shaped block 23 is slidably connected to the inside of the suspension seat 5, and one end of the T-shaped block 23 is fixedly connected with the rectangular rod 20. An auxiliary block 25 is fixedly connected to one side of the T-shaped block 23, and an auxiliary spring 24 is installed between the auxiliary block 25 and the suspension seat 5. The auxiliary impact member includes an L-shaped block 21 fixedly connected to the outer wall of one of the limit plates 8, and one end of the L-shaped block 21 penetrates to the outer wall of the sliding seat 9 and is slidably connected with the sliding seat 9. One side of each rotating shaft 31 is fixedly connected with a connecting shaft 33, and one end of the connecting shaft 33 is fixedly connected with an impact block 34, and the impact block 34 is attached to the outer wall of the L-shaped block 21;

[0038] When the welding torch 6 needs to move downward, the arc-shaped seat 7 can be pushed to drive the sliding seat 9 to move downward through the limit plate 8. When the spur gear 27 moves downward, it contacts the inclined surface on one side of the rotating tooth 28 and pushes the rotating tooth 28 to rotate. When the spur gear 27 separates from the rotating tooth 28, the torsion spring 32 no longer receives an external force to push the rotating tooth 28 to reset. Under the blocking action of the back surface of the rotating tooth 28 and the baffle 29, the spur gear 27 is limited, so that the staff does not need to continuously apply an extrusion force to the arc-shaped seat 7. Thus, the limit plate 8 can move downward with the welding torch 6 in an intermittent manner to block, thereby improving the overall stability of the device, more effectively blocking welding slag, and improving the stability of welding quality;

[0039] When the limit plate 8 moves to the lowest point and the staff needs to weld the lowest point, the welding torch 6 can be removed. Subsequently, the T-shaped block 23 can be pushed to drive the rectangular rod 20 to move horizontally, so that the rotating tooth 28 separates from the spur gear 27, and thus the spur gear 27 is no longer limited. Furthermore, the sliding seat 9 can move upward to reset under the action of the connecting spring 19. Subsequently, the staff can weld the lowest point through the welding torch 6;

[0040] When the rotating tooth 28 rotates away from the baffle 29, it drives the impact block 34 to rotate synchronously through the coupling shaft 33. When the spur gear 27 separates from the rotating tooth 28, the torsion spring 32 drives the impact block 34 to reset, so that the impact block 34 can impact the L-shaped block 21, and then act on the R-shaped stiffening rib 3 through resonance. In this way, the R-shaped stiffening rib 3 can generate slight vibrations during welding. The vibrations can make the liquid metal in the welding molten pool flow and mix better, help the gas escape, reduce the formation of defects such as pores, make the weld more dense, and improve the welding quality.

[0041] The above is only the preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, makes equivalent substitutions or changes, and all should be covered within the protection scope of the present invention.
