Description
Technical Field
[0001] This utility model relates to the field of building construction equipment technology, and in particular to a welding positioning device for a steel structure conversion column. Background Technology
[0002] The welding positioning device for steel structure transfer columns is a specialized piece of equipment used during the welding process of steel structure transfer columns in steel structure building construction. It is used to position, guide, and control the spacing of the weld joint. Its core function is to achieve precise alignment between the weld joint and the sidewall of the component by adapting to the gap characteristics of the steel structure transfer column, and to maintain a stable relative position during welding. This provides a precise positioning reference for the welding operation, thereby ensuring weld quality and construction efficiency. It is widely used in the connection construction of steel structure transfer columns in high-rise buildings, bridge projects, and other similar applications. In existing technologies, the welding positioning of steel structure transfer columns mostly relies on traditional manual marking or simple bracket fixing methods. Manual marking is not only inefficient but also highly dependent on the operator's experience, making it difficult to ensure the consistency of the distance between the weld joint and the side wall of the component, which can easily lead to quality problems such as uneven welds and weld deviations. Although simple brackets can provide some support, they are mostly designed with fixed specifications and cannot flexibly adapt to steel structure transfer columns with different gap sizes, resulting in poor versatility.
[0003] Therefore, it is necessary to provide a welding positioning device for steel structure transfer columns to solve the above-mentioned technical problems. Utility Model Content
[0004] To address the problems existing in the prior art, this utility model provides a welding positioning device for steel structure conversion columns.
[0005] The technical solution adopted by this utility model to solve its technical problem is: a welding positioning device for a steel structure conversion column, including a non-closed circular ring plate, a magnetic block, an inner ring, a threaded hole and a support plate. The arc of the non-closed circular ring plate is not less than 180°. The two non-closed circular ring plates are symmetrically provided with mounting grooves at the center of their opposite surfaces. The two mounting grooves are combined to form a mounting position. The outer ring of the two non-closed circular ring plates is welded with connecting blocks. The two connecting blocks are positioned by locking bolts. The magnetic block is embedded in the center of the outer ring of the non-closed circular plate, and the outer surface of the magnetic block is flush with the outer surface of the non-closed circular plate. The inner ring is rotatably installed at the mounting position, and a level bubble and a positioning rod are sequentially installed at the center of the inner sidewall of the inner ring, with the level bubble and the positioning rod being parallel to each other. The threaded holes are symmetrically arranged in one of the mounting slots, and an adjusting rod is installed in the threaded hole by threaded engagement. The number of support plates is two, and the two support plates are respectively close to the outer wall of the positioning rod. Leveling blocks are set on the inner side of the two support plates near the two ends. The two support plates are fixed together by positioning bolts, and positioning clamps are installed at the ends of the support plates.
[0006] Preferably, the two non-closed annular plates are provided with protrusions and grooves on their opposite surfaces, and the protrusions and grooves are mating parts.
[0007] Preferably, a wristband is provided at the center of the outer ring of the inner ring. The outer diameter of the wristband is smaller than the outer diameter of the non-closed ring plate, and the outer ring of the wristband has anti-slip texture.
[0008] Preferably, a trapezoidal groove is provided at the center of the upper end face of the support plate in the upper position, a trapezoidal block is slidably installed in the trapezoidal groove, a support plate is fixedly installed at the center of the top of the trapezoidal block, a threaded groove is provided at the side wall of the inner ring, and the top of the support plate is connected and fixed to the threaded groove by a screw.
[0009] Preferably, positioning blocks are inserted into both ends of the positioning rod, the two positioning blocks are fixed to the inner ring of the inner ring, steel balls are embedded in the end face of the positioning blocks, and the two side walls of the support plate are in contact with the steel balls but not connected.

[0011] Preferably, the top end face of the adjusting rod is provided with a placement groove, and a silicone pad is embedded in the placement groove.
[0012] Compared with related technologies, the welding positioning device for steel structure transfer columns provided by this utility model has the following advantages: This utility model provides a welding positioning device for steel structure transfer columns. The device includes components such as a non-enclosed circular ring plate. As long as the gap between the steel structure transfer columns is smaller than the outer diameter of the non-enclosed circular ring plate, the plate can be easily placed into the gap. This eliminates the need for custom-made devices for different gap sizes, effectively improving the adaptability to gaps of steel structure transfer columns of different specifications and expanding the device's applicability. Furthermore, due to the non-enclosed circular ring plate's outer arc surface and non-enclosed characteristics, installation does not require complex alignment or fitting operations. Simply place the non-enclosed circular ring plate into the gap of the steel structure transfer column, and then use the magnetic blocks embedded in the outer wall to adhere it to the edge of the steel structure transfer column for quick fixation, saving installation time and improving work efficiency.
[0013] This invention provides a welding positioning device for steel structure transition columns. This invention ensures that the distance between the positioning clamp used to hold the welding head and the steel structure transition column remains consistent during the movement of the support plate, keeping the welding head in the ideal welding position. This guarantees the uniformity and consistency of the weld, thereby improving welding quality and stability, and reducing welding defects caused by distance changes, such as weld deviation and weld beads. Furthermore, when operating the support plate for welding, workers do not need to constantly monitor and adjust the distance between the positioning clamp and the steel structure transition column, reducing the complexity and workload of the operation, making the operation smoother, and lowering the skill requirements for operators. Even workers with relatively little experience can easily complete high-quality welding positioning and welding operations. Attached Figure Description

[0015] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.
[0016] Furthermore, the terms used below are defined based on the functions of this utility model and may vary depending on the user's or operator's intent or convention. Therefore, these terms are defined based on the entire contents of this specification.
[0017] Please see Figures 1-5The present invention provides a welding positioning device for a steel structure conversion column, comprising a non-closed circular ring plate 1, a magnetic block 2, an inner ring 3, a threaded hole 4, and a support plate 5. The non-closed circular ring plate 1 has an arc of not less than 180°, that is, the non-closed circular ring plate 1 has an opening to accommodate the passage of the welding head. Two non-closed circular plates 1 are symmetrically provided with mounting grooves 10 at the center of their opposite surfaces. The two mounting grooves 10 are combined to form a mounting position. Connecting blocks 12 are welded to the outer ring of both non-closed circular plates 1. The two connecting blocks 12 are positioned by locking bolts 13, meaning that the two non-enclosed circular plates 1 are detachable for easy maintenance. The two non-closed circular plates 1 are respectively provided with protrusions and grooves on their opposite surfaces. The protrusions and grooves are mating parts. When the two non-closed circular plates 1 are fastened and fixed, the protrusions will enter into the grooves, and the two will further lock the circumferential position of the two non-closed circular plates 1. The magnetic block 2 is embedded in the center of the outer ring of the non-closed circular plate 1, and the outer surface of the magnetic block 2 is flush with the outer surface of the non-closed circular plate 1. An annular groove is provided on the other side of the non-enclosed annular plate 1. The annular groove is connected to the installation position of the magnetic block 2. On the one hand, it reduces the overall weight of the non-enclosed annular plate 1, making it easier for construction personnel to operate during installation. On the other hand, the condition of the magnetic block 2 can be visually observed through the annular groove, and the magnetic block 2 can be quickly replaced. like Figure 1 As shown, the outer magnetic block 2 of the non-closed circular plate 1 can be adsorbed at the gap of the steel structure conversion column, and can be flexibly inserted into it according to the actual size of the gap of the steel structure conversion column. As long as the gap size of the steel structure transfer column is smaller than the outer diameter of the non-enclosed circular plate 1, the non-enclosed circular plate 1 can be successfully placed at the gap of the steel structure transfer column. There is no need to customize a special device for different gap sizes, which effectively improves the adaptability to gaps of steel structure transfer columns of different specifications and expands the applicability of the device. Furthermore, due to the outer arc surface and non-closed characteristics of the non-enclosed circular plate 1, there is no need for complicated alignment and fitting operations during installation. Simply place the non-enclosed circular plate 1 into the gap of the steel structure conversion column, and then use the magnetic block 2 embedded in the outer wall to attach it to the edge of the steel structure conversion column to quickly complete the fixation, saving installation time and improving work efficiency. Furthermore, when the non-closed circular plate 1 comes into contact with the gap between the steel structure conversion column, the outer wall of the magnetic block 2 can fit the contour of the gap well. With the adsorption force of the magnetic block 2, it can stably support the subsequent welding positioning components, providing a solid foundation for welding positioning operations and reducing problems such as welding deviation caused by unstable device fixation. Generally speaking, the magnetic block 2 embedded on the outside of the non-closed circular plate 1 is attracted to the vertical edge of the steel structure transfer column, which can be understood as the position of the steel structure transfer column to the left or right. The inner ring 3 is rotatably installed at the mounting position. A horizontal bubble 31 and a positioning rod 32 are sequentially installed at the center of the inner side wall of the inner ring 3, and the horizontal bubble 31 and the positioning rod 32 are parallel to each other. In actual operation, after the non-closed circular plate 1 is adsorbed into the gap of the steel structure conversion column, the inner ring 3 can be manually rotated, and the positioning rod 32 is parallel to the outer wall of the steel structure conversion column when the bubble level 31 is centered by visual inspection of the bubble level 31. The interior of the mounting groove 10 and the outer wall of the inner ring 3 are both smooth surfaces, and lubricating grease is applied at the connection between the inner ring 3 and the mounting groove 10. The lubricating grease reduces the mutual friction between the interior of the mounting groove 10 and the outer wall of the inner ring 3. Meanwhile, a wristband 33 is provided in the center of the outer ring of the inner ring 3, which makes it easier for construction workers to rotate the inner ring 3 through the wristband 33 and the lubricating grease. The outer diameter of the wristband 33 is smaller than the outer diameter of the non-closed circular plate 1. When installing the non-closed circular plate 1, the position of the outer ring of the wristband 33 is not correct for positioning the non-closed circular plate 1, causing interference. Furthermore, the outer ring of the wristband 33 has anti-slip texture, so the construction workers will not slip when holding the wristband 33; A rubber sleeve can be embedded in the outer wall of the connecting block 12. When it is necessary to adjust the position of the non-closed circular plate 1 relative to the rod structure conversion column, the construction personnel can manually hold the rubber sleeve and squeeze it clockwise or counterclockwise to adjust it. Threaded holes 4 are symmetrically arranged in one of the mounting grooves 10. An adjusting rod 41 is installed in the threaded hole 4 by threaded engagement. Before rotating the inner ring 3, the adjusting rod 41 should be rotated so that its end position is separated from the inner ring 3. When the positioning rod 32 is parallel to the outer wall of the steel structure conversion column, rotate the adjusting rod 41 again so that the top of the adjusting rod 41 is close to the side wall of the inner ring 3, and the position of the inner ring 3 relative to the installation position is locked under the action of the squeezing force and friction. The top end face of the adjusting rod 41 is provided with a placement groove, and a silicone pad is embedded in the placement groove. When the adjusting rod 41 is rotated, the silicone pad is driven to directly contact the side wall of the inner ring 3, which further increases the locking strength of the inner ring 3. A support plate 5 is provided on the outer side of the positioning rod 32. There are two support plates 5, and the two support plates 5 are respectively close to the outer wall of the positioning rod 32. A leveling block 51 is provided on the inner side of the two support plates 5 near the two ends. The two support plates 5 are fixed together by positioning bolts. After the positioning bolts are fixed, the two support plates 5 are parallel to each other. The two parallel support plates 5 can slide along the outer wall of the positioning rod 32. Since the two support plates 5 are detachable, multiple support plates 5 of different lengths can be equipped in the actual design. When using steel structure transfer columns of different sizes, support plates 5 of different lengths are selected and installed on the outside of the steel structure transfer columns, but the length of the support plate 5 must be greater than the width of the steel structure transfer column. A positioning clamp 6 is installed at the end of the support plate 5. The positioning clamp 6 is used to clamp and fix the welding head. In actual operation, one end of the support plate 5 (the end with the positioning clamp 6) is pulled to the edge of the steel structure conversion column. Then, during the welding operation, the support plate 5 is moved along the positioning rod 32 by the movement of the welding head. At this time, the welding operation can be completed horizontally. Positioning blocks 30 are inserted into both ends of the positioning rod 32. The two positioning blocks 30 are fixed to the inner ring of the inner ring 3. Steel balls 301 are embedded in the end face of the positioning blocks 30. The two side walls of the support plate 5 are in contact with the steel balls 301 but not connected. When the support plate 5 moves relative to the positioning rod 32, the two side walls of the support plate 5 will slide along the surface of the steel balls 301, while the steel balls 301 roll relative to the support plate 5, reducing the wear of the two side walls of the support plate 5 and making the slide of the support plate 5 smoother.
[0018] In another embodiment, see Figures 1-5 A trapezoidal groove 52 is provided at the center of the upper end face of the support plate 5, and a trapezoidal block 34 is slidably installed in the trapezoidal groove 52. A support plate 35 is fixedly installed at the center of the top of the trapezoidal block 34, and the trapezoidal block 34 can slide along the inside of the trapezoidal groove 52. The inner ring 3 has a threaded groove 36 on its side wall. The top of the support plate 35 is connected and fixed to the threaded groove 36 by a screw 37. When the support plate 5 is moved, the trapezoidal block 34 at the bottom of the support plate 35 is moved in the trapezoidal groove 52. The two work together to lock the longitudinal position of the support plate 5 (i.e. the distance value between it and the steel structure conversion column). In this embodiment, it can be ensured that the distance between the positioning clamp 6 used to hold the welding head and the steel structure conversion column remains consistent during the movement of the support plate 5, so that the welding head is always in the ideal welding position, ensuring the uniformity and consistency of the weld, thereby improving the quality and stability of the welding and reducing welding defects caused by distance changes, such as weld deviation and weld beads. In terms of operation, when workers are welding the support plate 5, they do not need to constantly pay attention to and adjust the distance between the positioning clamp 6 and the steel structure conversion column, which reduces the complexity and workload of the operation process, making the operation smoother and lowering the skill level requirements of the operators. Even workers with relatively little experience can easily complete high-quality welding positioning and welding operations.
