TECHNICAL FIELD

[0001] The application relates to the technical field of building construction, in particular to a steel member welding platform. BACKGROUND

[0002] In recent years, fabricated steel structure buildings are increasingly popular, and more and more steel structure high-rise buildings are built, and the work load of steel column butt welding is increasing. In high-rise steel structure engineering, as the height increases, a steel member welding platform needs to be used to assist construction personnel in welding work.

[0003] The existing Chinese patent (authorization announcement number: CN219638344U) discloses a steel member welding platform. The steel member welding platform comprises a base, a construction support assembly is arranged on the base, the construction support assembly comprises a tray arranged on the base, an upper surface of the tray is provided with a guide groove, and a guide rail is slidably connected in the guide groove. The construction support assembly is arranged, the extension strokes of the output ends of the telescopic rods are inconsistent, the tray can be inclined toward the end with the shortest extension stroke of the output ends of the telescopic rods, the angle of the tray is adjusted, the device can adapt to different working environments during use, the angle of the adjusting plate is adjusted through the cooperation of the guide groove and the guide rail, then the adjusting plate is displaced on the supporting disc through the sliding block and the cross slot, the position of the adjusting plate is adjusted, so that the device can support different regions of the steel structure and facilitate construction.

[0004] When the existing steel member welding platform is used for welding between steel structures, the welding platform carried by construction personnel is lifted to the vicinity of the welding position through the lifting rod, a crane or the like is used to lift and move the cross beam to the vicinity of the welding position, one of the two construction personnel positions the cross beam and the welding position, the other person welds the cross beam and the steel structure, and then the other end of the cross beam is welded again, so that the cross beam can be welded between the steel structures. However, when the existing device is used for welding, if the cross beam needs to be inclined and welded on the steel structure, the cross beam is inclined through the cooperation of the crane and manpower, the construction personnel need to position the cross beam for a long time, the physical consumption of the construction personnel is large, the cross beam is easy to shake, the welding position is easy to deviate, and the physical consumption of the construction personnel is large, which is very inconvenient. SUMMARY

[0005] The application aims to solve the problems of large manual physical consumption and easy welding position deviation of the existing steel member welding platform during welding, and provides a steel member welding platform.

[0006] In order to achieve the above-mentioned purpose, the application specifically adopts the following technical scheme:

[0007] Furthermore, a steel component welding platform includes a base, a receiving plate installed at the upper end of the lifting rod, a welding table installed on the receiving plate, a control console fixedly connected to the welding table, a station plate fixedly connected to the welding table, a limiting structure provided on the welding table, a rotating structure provided between the receiving plate and the welding table, and a positioning structure provided on the welding table.

[0008] By adopting the above technical solution, when welding steel structures, the device can make it easier to align the welding table horizontally with the steel structure through the cooperation of the positioning structure and the rotating structure, reducing the deviation during welding. Furthermore, the positioning structure and the limiting structure work together to facilitate the limiting of the crossbeam between the steel structures, making it easier to adjust the welding position when welding the crossbeam between the steel structures. This reduces the need for manual assistance when welding the ends of the crossbeam, making the welding position more accurate and the welding more convenient.

[0009] Furthermore, the limiting structure includes a movable frame fixedly connected to the welding table, a movable threaded rod rotatably connected inside the movable frame, a translation motor fixedly connected to the outside of the movable frame, the translation motor being electrically connected to the control console, the output end of the translation motor passing through the movable frame and fixedly connected to the movable threaded rod, and a lifting assembly being provided on the welding table.

[0010] By adopting the above technical solution, the crossbeam can be moved horizontally on the welding table by moving the moving threaded rod through the moving motor. This facilitates the movement of the crossbeam during welding, making it easier to weld and allowing it to fit more closely to the welding parts of the steel structure.

[0011] Furthermore, the lifting assembly includes a lifting frame threadedly connected to a translation threaded rod, a lifting threaded rod rotatably connected inside the lifting frame, a guide column fixedly connected inside the lifting frame, a lifting motor fixedly connected to the upper end of the lifting frame, the lifting motor electrically connected to the control console, the output end of the lifting motor passing through the lifting frame and fixedly connected to the lifting threaded rod, and a clamping assembly provided on the lifting frame.

[0012] By adopting the above technical solution, the lifting mechanism drives the lifting screw to rotate, allowing the crossbeam to move on the welding platform and be adjusted to a suitable position for construction personnel to operate, making the device more convenient to use and easier to perform manual welding.

[0013] Furthermore, the clamping assembly includes a rotary motor threadedly connected to a lifting threaded rod, the rotary motor being electrically connected to a control console, a clamping block being fixedly connected to the output end of the rotary motor, an opposing threaded rod being rotatably connected inside the clamping block, a throttle being rotatably connected to the upper end of the clamping block, the throttle being fixedly connected to the opposing threaded rod, a clamping plate one and a clamping plate two being threadedly connected to the opposing threaded rod, and a crossbeam being placed between the clamping plate one and the clamping plate two.

[0014] By adopting the above technical solution, the clamping plate one and clamping plate two can be driven to clamp the crossbeam from both sides by rotating the throttle, which enhances the clamping effect of the device and makes the device more stable when welding the crossbeam without the need for manual positioning.

[0015] Furthermore, the positioning structure includes a connecting rod fixedly connected to the lifting frame. The connecting rod is located between the welding table and the station plate. The connecting rod is slidably connected to both the welding table and the station plate. A positioning rod is fixedly connected to the end of the connecting rod. An extension component is provided on the positioning rod. A marking component is provided on the positioning rod.

[0016] By adopting the above technical solution, when the welding table moves between the steel structure and the steel structure, the positioning rod will first fit against the side of the steel structure. By observing the degree of fit, the welding table is adjusted so that the welding table can be set horizontally with the steel structure, resulting in better and more stable welding effect on the beam.

[0017] Furthermore, the extension assembly includes an electric telescopic rod fixedly connected to the connecting rod, the electric telescopic rod being electrically connected to the control console, and a telescopic plate being fixedly connected to the telescopic end of the electric telescopic rod.

[0018] By adopting the above technical solution, the control console drives the electric telescopic rod to extend, which allows the telescopic plate to be extended, facilitating its fit with the steel structure and enhancing the auxiliary positioning effect of the device, enabling it to measure the level between steel structures with different spacing.

[0019] Furthermore, the marking assembly includes a sliding column fixedly connected within the telescopic plate, a sliding block slidably connected to the sliding column, a fixed column fixedly connected to the upper end of the sliding block, the fixed column slidably connected to the telescopic plate, a marking block sleeved on the fixed column, a spring sleeved on the fixed column, a limit block fixedly connected to the upper end of the fixed column, and the spring, the limit block, and the marking block are all fixedly connected.

[0020] By adopting the above technical solution, and aligning the marking block with both ends of the crossbeam, the crossbeam and the positioning rod can be moved together by the connecting rod when the auxiliary positioning welding table is connected to the steel structure, so that the crossbeam can be positioned between the steel structures.

[0021] Furthermore, the rotating structure includes a rotating gear rotatably connected to the upper end of the receiving plate, a transmission gear rotatably connected to the receiving plate, the transmission gear meshing with the rotating gear, a rotating motor fixedly connected to the lower end of the receiving plate, the rotating motor electrically connected to the control console, the output end of the rotating motor passing through the receiving plate and fixedly connected to the transmission gear, the upper end of the rotating gear fixedly connected to the lower end of the welding table, a guide groove provided on the receiving plate, a ring slidably connected in the guide groove, and the ring fixedly connected to the lower end of the welding table.

[0022] By adopting the above technical solution, the rotating motor drives the welding table to adjust the angle of the telescopic plate, so that both ends of the telescopic plate are in contact with the steel structure. This allows the welding table and the steel structure to be set horizontally without the need for adjustment from the base, making the device more convenient to adjust and more convenient to use.

[0023] In summary, this application includes at least one of the following beneficial effects;

[0024] In this application, when using this device to weld a crossbeam to a steel structure, the crossbeam is first placed between clamping plate one and clamping plate two. The handle is rotated to clamp the crossbeam. When the lifting rod raises the welding table, the crossbeam also rises and moves accordingly. Then, a rotating motor drives a transmission gear, which in turn drives a rotating gear, causing the welding table to rotate and adjust the welding position. This makes it easier for the device to adjust the welding position of the crossbeam, resulting in more accurate welding. The device's limitation of the crossbeam reduces the shaking caused by manual limitation, making the welding process more stable and reducing manual labor. Simultaneously, before moving the base towards the steel structure, the positioning rod on the welding table will be close to the surface of the steel structure. At this time, the welding... The angle between the positioning rod and the steel structure is adjusted to ensure the positioning rod fits snugly against the steel structure surface, thus assisting in the positioning of the welding table and the steel structure. This ensures that the welding table and the steel structure are in a horizontal position, allowing the crossbeam to be placed horizontally between the steel structures to be welded. This results in a more horizontal fit between the crossbeam and the welding area, further improving welding accuracy. After the positioning rod helps to level the crossbeam and the steel structure, a moving motor drives the connecting rod to move the positioning rod horizontally between the steel structures, facilitating the movement of the welding table. Simultaneously, the moving motor drives the lifting frame to move in the same way as the positioning rod, also leveling the crossbeam between the steel structures, making it easier to place the crossbeam between the steel structures and further improving the convenience of welding.

[0025] In this application, when using this device to weld buildings with special appearance requirements, such as cultural centers and memorial halls, the control console starts the lifting motor to drive the lifting threaded rod to rotate, causing the clamping block to move up and down along the guide column. Then, the control console starts the rotary motor to drive the clamping block to rotate, so that the crossbeam can be tilted and lifted on the welding table during welding. This allows the crossbeam to adapt to more complex welding requirements, such as complex structures requiring multiple angles. The device can also adapt to these requirements by limiting the crossbeam in different ways, making it more convenient for manual welding of complex structures and reducing labor costs.

[0026] In this application, after the limiting structure limits the crossbeam, the telescopic plate extends from both ends of the positioning rod through the electric telescopic rod on the positioning rod. The sliding block on the sliding telescopic plate causes the marker block to move, so that the distance between the marker blocks is equal to the length of the crossbeam, and at the same time, the marker block and the crossbeam are horizontally aligned. When the positioning rod performs auxiliary positioning between the steel structure and the welding table, the position of the crossbeam can be pre-judged through the marker block, which facilitates the device to adjust the crossbeam between the steel structures, making it easier to perform auxiliary positioning between the steel structures.

[0034] The following is in conjunction with the appendix Figures 1-5 This application will be described in further detail.

[0035] This application discloses a steel component welding platform.

[0036] Reference Figure 1 A steel component welding platform includes a base 1, a lifting rod 2 installed on the upper end of the base 1, a receiving plate 3 installed on the upper end of the lifting rod 2, a welding table 4 installed on the receiving plate 3, a control console 5 fixedly connected to the welding table 4, a station plate 14 fixedly connected to the welding table 4, a limiting structure provided on the welding table 4, a rotating structure provided between the receiving plate 3 and the welding table 4, and a positioning structure provided on the welding table 4.

[0037] When welding of the crossbeam 12 between the steel structures is required during construction, the crossbeam 12 is first fixed to the welding platform 4 by the limiting structure on the welding platform 4. Then, the base 1 is moved to the vicinity of the steel structure to be welded. Workers then sit on the welding platform 4, and the lifting rod 2 hydraulically raises the welding platform 4 to a height close to the welding area. The position of the welding platform 4 is then adjusted by the rotating structure so that the crossbeam 12 on the welding platform 4 is nearly horizontal with the steel structure to be welded. The device supporting the base 1 then moves the base 1 towards the steel structure. During this movement, the positioning structure first touches the steel structure. By observing the positioning structure, the rotating structure is adjusted to make the positioning structure parallel to the steel structure. At this point, the crossbeam 12 is also parallel to the steel structure. The positioning structure is then adjusted to move further. The device can be positioned between steel structures. While adjusting the positioning structure, the limiting structure maintains the same movement. Then, when the base 1 is moved between the steel structures, the crossbeam 12 can be positioned between the steel structures. The limiting structure then adjusts the welding position of the crossbeam 12. Then, the construction personnel weld the crossbeam 12 onto the steel structure. This allows the device to make it easier to align the welding table 4 horizontally with the steel structure through the cooperation of the positioning and rotating structures, reducing welding deviations. The cooperation of the positioning and limiting structures facilitates the limiting of the crossbeam 12 between the steel structures, making it easier to adjust the welding position when welding the crossbeam 12 between the steel structures. This reduces the need for manual assistance when welding the ends of the crossbeam 12, making the welding position more accurate and the welding more convenient.

[0038] Reference Figure 2 and Figure 3 The limiting structure includes a movable frame 17 fixedly connected to the welding table 4, a movable threaded rod 18 rotatably connected inside the movable frame 17, a translation motor 21 fixedly connected to the outside of the movable frame 17, the translation motor 21 being electrically connected to the control console 5, and the output end of the translation motor 21 passing through the movable frame 17 and fixedly connected to the movable threaded rod 18. A lifting assembly is provided on the welding table 4. The lifting assembly includes a lifting frame 6 threadedly connected to the translation threaded rod, a lifting threaded rod 19 rotatably connected inside the lifting frame 6, a guide post 20 fixedly connected inside the lifting frame 6, a lifting motor 7 fixedly connected to the upper end of the lifting frame 6, the lifting motor 7 being electrically connected to the control console 5, the output end of the lifting motor 7 passing through the lifting frame 6 and fixedly connected to the lifting threaded rod 19, and a clamping assembly provided on the lifting frame 6.

[0039] The clamping assembly includes a rotary motor 8 threadedly connected to a lifting threaded rod 19. The rotary motor 8 is electrically connected to the control console 5. A clamping block 9 is fixedly connected to the output end of the rotary motor 8. An opposing threaded rod 26 is rotatably connected inside the clamping block 9. A handle 13 is rotatably connected to the upper end of the clamping block 9. The handle 13 is fixedly connected to the opposing threaded rod 26. A clamping plate 10 and a clamping plate 21 are threadedly connected to the opposing threaded rod 26. A crossbeam 12 is placed between the clamping plate 10 and the clamping plate 21.

[0040] When steel structure welding is required using this device, the crossbeam 12 is placed between clamping plate 10 and clamping plate 11. Rotating the handle 13 drives the opposing threaded rod 26 to rotate, causing clamping plate 10 and clamping plate 11 to move towards each other, clamping the crossbeam 12. When the lifting rod 2 lifts the welding table 4, the crossbeam 12 also lifts and moves accordingly. This means that the device does not require a crane to assist in welding the crossbeam 12. When the welding table 4 moves between the steel structures, the lifting motor 7 can be started through the control console 5 to drive the lifting threaded rod 19 to rotate, causing the clamping block 9 to move up and down along the guide column 20. Alternatively, the rotary motor 8 can be started through the control console 5 to drive the clamping block 9 to rotate, tilting and lifting the crossbeam 12. This allows the crossbeam 12 to be welded without requiring a lot of manual labor when adjusting the welding position, saving the physical labor of construction workers. It also makes adjusting the welding position more convenient, more stable during welding, and easier to use.

[0041] Reference Figure 1 and Figure 4 The positioning structure includes a connecting rod 34 fixedly connected to the lifting frame 6. The connecting rod 34 is located between the welding table 4 and the station plate 14. The connecting rod 34 is slidably connected to both the welding table 4 and the station plate 14. A positioning rod 15 is fixedly connected to the end of the connecting rod 34. An extension component and a marking component are provided on the positioning rod 15. The extension component includes an electric telescopic rod 16 fixedly connected to the connecting rod 34. The electric telescopic rod 16 is electrically connected to the control console 5. A telescopic plate 27 is fixedly connected to the telescopic end of the electric telescopic rod 16. The marking component includes a sliding column 28 fixedly connected to the telescopic plate 27. A sliding block 29 is slidably connected to the sliding column 28. A fixed column 31 is fixedly connected to the upper end of the sliding block 29. The fixed column 31 is slidably connected to the telescopic plate 27. A marking block 30 is sleeved on the fixed column 31. A spring 32 is sleeved on the fixed column 31. A limit block 33 is fixedly connected to the upper end of the fixed column 31. The spring 32 is fixedly connected to both the limit block 33 and the marking block 30.

[0042] Before welding between the steel structures, the electric telescopic rod 16 is activated via the control console 5 to extend the telescopic plate 27 until both ends are larger than the gap between the steel structures. Then, the marker block 30 is pulled up, and the sliding block 29 is slid along the sliding column 28 so that the distance between the two marker blocks 30 is equal to the length of the crossbeam 12. The marker blocks 30 are then horizontally aligned with both ends of the crossbeam 12. The spring 32 of the marker blocks 30 is released, and the marker blocks 30 are pushed to contact the telescopic plate 27. Then, the welding table 4 is moved between the steel structures so that the telescopic plate 27 is in contact with the steel structure surfaces on both sides. When the telescopic plate 27 is in contact with the steel structure surface, it indicates that the welding table 4 is horizontal with the steel structure. Then, the moving motor is driven by the control panel to rotate, causing the lifting frame 6 to move along the moving threaded rod 18, and at the same time, the positioning rod 15 is moved so that the two ends of the telescopic plate 27 are aligned. Each marker block 30 is positioned between the steel structure and the gap. Simultaneously, the crossbeam 12 is moved to a suitable horizontal position for welding the steel structure. At this point, the electric telescopic rod 16 is retracted via the control panel, preventing it from contacting the side of the steel structure. Then, the base 1 is moved to move the welding between the steel structures, bringing the crossbeam 12 into the gap and aligning it with the welding area. This allows the device to provide auxiliary positioning between the welding table 4 and the steel structure before welding, reducing the need for adjustments between the crossbeam 12 and the steel structure during welding and resulting in more accurate welding. It also allows for adjustment of the position of the crossbeam 12, facilitating the movement of the welding table 4 to bring the crossbeam 12 into the gap between the steel structures. This reduces the adjustment trouble caused by the crossbeam 12 hitting the steel structure during movement, making the device more convenient to use and easier to perform auxiliary positioning between the steel structures.

[0043] Reference Figure 5 The rotating structure includes a rotating gear 23 rotatably connected to the upper end of the receiving plate 3, a transmission gear 24 rotatably connected to the receiving plate 3, the transmission gear 24 meshing with the rotating gear 23, a rotating motor 25 fixedly connected to the lower end of the receiving plate 3, the rotating motor 25 being electrically connected to the control console 5, the output end of the rotating motor 25 passing through the receiving plate 3 and fixedly connected to the transmission gear 24, the upper end of the rotating gear 23 being fixedly connected to the lower end of the welding table 4, a guide groove being provided on the receiving plate 3, a ring 22 being slidably connected in the guide groove, and the ring 22 being fixedly connected to the lower end of the welding table 4.

[0044] When welding irregularly arranged steel structures, the control console 5 drives the rotating motor 25 to drive the transmission gear 24, which in turn drives the rotating gear 23 to rotate the welding table 4 on the receiving plate 3. This facilitates the tilting and adjustment of the crossbeam 12, making the device suitable for complex steel structure welding work and expanding its applicability. When the telescopic plate 27 is attached to the steel structure and one end cannot be stably attached, the angle of the telescopic plate 27 can be adjusted by rotating the welding table 4, so that both ends of the telescopic plate 27 are attached to the steel structure. This allows the welding table 4 to be set horizontally with the steel structure without the need for adjustment from the base 1, making the device more convenient to adjust and use.

[0045] Working principle: When welding crossbeams 12 between steel structures during construction, the crossbeams 12 are placed between clamping plates 10 and 11. Turning the handle 13 rotates the opposing threaded rods 26, causing clamping plates 10 and 11 to move towards each other, clamping the crossbeams 12. Then, the control console 5 activates the electric telescopic rod 16, extending the telescopic plate 27 until both ends are larger than the gap between the steel structures. Next, the marker block 30 is pulled up, causing the sliding block 29 to slide along the sliding column 28, so that the distance between the marker blocks 30 at both ends is equal to the length of the crossbeam 12. Then, mark blocks 30 are horizontally aligned with both ends of the crossbeam 12. Then, release the spring 32 of the mark blocks 30 to reset and push the mark blocks 30 against the telescopic plate 27. Then, move the base 1 to the vicinity of the steel structure to be welded. Then, the staff sits on the welding table 4. The lifting rod 2 hydraulically drives the welding table 4 to a height close to the welding part. The control console 5 drives the rotating motor 25 to drive the transmission gear 24, which drives the rotating gear 23 to rotate the welding table 4 on the receiving plate 3, which facilitates the tilting and adjustment of the position of the crossbeam 12.

[0046] Then, the device supporting the base 1 drives the base 1 to move between the steel structures, so that the telescopic rod is in contact with the steel structure surfaces on both sides. When the telescopic plate 27 is in contact with the steel structure surface, it means that the welding table 4 is horizontal with the steel structure. Then, the control panel drives the moving motor to rotate, so that the lifting frame 6 moves along the moving threaded rod 18, and at the same time drives the positioning rod 15 to move, so that the two marking blocks 30 on the telescopic plate 27 are in the gap with the steel structure. At the same time, the crossbeam 12 also moves to the appropriate horizontal position for welding the steel structure. At this time, the control panel starts the electric telescopic rod 16 to retract so that the telescopic rod is no longer in contact with the side of the steel structure. Then, the base 1 is moved to move the welding from between the steel structures, and the crossbeam 12 is brought into the space between the steel structures to align with the welding part.

[0047] At this time, the crossbeam 12 is also parallel to the steel structure. Then, the positioning structure is adjusted to move so that it can be located between the steel structures. While adjusting the positioning structure, the limiting structure moves in the same way. Then, when the base 1 is moved between the steel structures, the crossbeam 12 can also be located between the steel structures. Then, the lifting motor 7 and the rotating motor 8 drive the clamping block 9 to adjust the crossbeam 12. Then, the construction personnel weld the crossbeam 12 to the steel structure.
