Description

Technical Field

[0001] The invention relates to the technical field of steel structure weld processing, and in particular to a large steel structure weld processing device. Background Art

[0002] Steel structure is a structure made of steel materials and is one of the main types of building structures. The structure is mainly composed of steel beams, steel columns, steel trusses and other components made of steel sections and steel plates. When the welds of steel columns are processed, the welds on the outside of the steel columns are generally polished using weld processing equipment to ensure the smoothness of the surface of the steel columns. Since the surface of the steel columns is relatively smooth, clamping assemblies are required to clamp both ends of the steel columns to ensure the stability of the steel columns during polishing. When the steel columns are being polished, the clamping parts of the steel columns are subjected to greater support force because the clamping assemblies clamp both ends of the steel columns. However, the steel columns are in a hollow state in the clamping assemblies, so that there is a single-point support between the steel columns and the clamping assemblies, resulting in a relatively concentrated stress on the steel columns in the clamping assemblies, which causes cracks or fractures in the steel columns due to stress concentration, increasing the difficulty of steel column weld processing and reducing weld processing efficiency. Summary of the invention

[0003] The purpose of the present invention is to provide a large-scale steel structure weld processing equipment. Through the setting of the guide assembly, it is possible to support the steel column in multiple sections within the clamping sleeve, which can effectively disperse the weight and stress of the steel column, avoid the stress concentration that may be caused by single-point support, and reduce the risk of cracks or fractures caused by stress concentration, thereby improving the stability and processing accuracy of the entire structure to solve the above-mentioned deficiencies in the technology.

[0022] When the steel column 11 needs to be supported, the clamping sleeve 12 first pre-restricts the steel column 11 so that the steel column 11 fits the guide seat 33 but is not too tight. The servo motor 26 drives the rotating column 25 to rotate, and then the rotating column 25 rotates to drive the gear 23 to rotate. At this time, the gear 23 rotates and engages with the gear ring 22 to drive the clamping sleeve 12 to rotate along the first support frame 21, and the connecting ring 24 rotates along the outside of the auxiliary wheel 28 to rotate the steel column 11 along the guide seat 33, which is convenient for observing the surface of the steel column 11.

[0023] refer to Figure 1 , Figure 8 and Fig. 9 As shown, the cleaning component 5 includes a mounting frame 51 mounted on the top of the guide seat 33, a cleaning scraper 52 mounted on the mounting frame 51 and fitted to the outside of the steel column 11, and a scraper rod 53 fixed on one side of the cleaning scraper 52, and a through groove for the scraper rod 53 to be inserted is provided at one end of the mounting frame 51, a first connecting plate 55 is fixed at one end of the scraper rod 53, a mounting groove 54 for the first connecting plate 55 to slide is provided in the through groove, and a spring 56 is installed between the mounting groove 54 and the first connecting plate 55; the cleaning component 5 also includes a second connecting plate 57 mounted in the mounting groove 54, a connecting rod 58 fixed in the mounting groove 54 and a threaded hole provided in the through groove, and the second connecting plate 57 is sleeved on the outside of the connecting rod 58, an adjusting bolt 59 is threaded in the threaded hole, and one end of the adjusting bolt 59 extends into the mounting groove 54 and is rotatably mounted on one end of the second connecting plate 57.

[0024] Through the above technical solution: When the pressure between the cleaning scraper 52 and the steel column 11 is adjusted, the adjusting bolt 59 is rotated along the threaded hole, and then the adjusting bolt 59 is rotated along one side of the second connecting plate 57 and pushes the second connecting plate 57 to move forward along the mounting groove 54. At this time, the second connecting plate 57 moves in the mounting groove 54 to push the spring 56 to move, and the spring 56 moves to push the first connecting plate 55 to move, so that the scraper rod 53 slides along the mounting groove 54 and the through groove, and the cleaning scraper 52 is brought closer to the surface of the steel column 11, and the tension of the spring 56 between the second connecting plate 57 and the first connecting plate 55 is adjusted. At the same time, the mutual squeezing pressure between the cleaning scraper 52 and the steel column 11 is adjusted to facilitate the stable fitting of the cleaning scraper 52 to the surface of the steel column 11.

[0025] refer to Figure 1 , Figure 2 , Figure 5 , Figure 6 and Figure 7 As shown, the control assembly 4 includes a control ring 42 slidably sleeved on the outside of the rotating column 25 and a connecting ring 41 fixed to one end of the threaded column 34, and one end of the connecting ring 41 passes through the guide bearing box 31 and is fixed with a second gear disc 44, and the outside of the control ring 42 is fixed with a first gear disc 43 that matches the second gear disc 44, and the guide bearing box 31 is provided with a push rod assembly that pushes the control ring 42 to move and is fixed; the push rod assembly includes a receiving ring 45 installed on the control ring 42 and a connecting rod 46 slidably installed on the top of the guide bearing box 31, and the bottom end of the connecting rod 46 is fixedly connected to the outside of the receiving ring 45, a first screw hole 48 is opened at the top of the connecting rod 46, and a plurality of second screw holes 49 are opened at the top of the guide bearing box 31, a control threaded rod 47 is screwed on the connecting rod 46, and the control threaded rod 47 passes through the first screw hole 48 and is screwed into the second screw hole 49 corresponding to the first screw hole 48.

[0026] Through the above technical solution: When the distance between the guide assembly 3 and the steel column 11 is adjusted appropriately, and the detection assembly 2 needs to rotate continuously, first stop the drive of the servo motor 26, and rotate the control threaded rod 47 to remove it from the first screw hole 48 and one of the second screw holes 49, so that the restriction between the connecting rod 46 and the guide bearing box 31 is lost. At this time, the connecting rod 46 is pushed to move along the guide bearing box 31 to drive the receiving ring 45 to move synchronously, and the receiving ring 45 moves to drive the control ring 42 to slide along the outside of the rotating column 25, so that the control ring 42 moves to drive the first toothed disc 43 to approach the end of the rotating column 25, and the first toothed disc 43 moves during the movement process. The connecting rod 46 moves slowly outward from the second toothed disc 44, thereby losing the connection between the first toothed disc 43 and the second toothed disc 44. As the connecting rod 46 moves, the first screw hole 48 overlaps with the other second screw hole 49, and then the control threaded rod 47 is screwed into the first screw hole 48 and the other second screw hole 49 again, and the connecting rod 46 and the guide bearing box 31 are screwed together. Subsequently, the servo motor 26 drives the rotating column 25 to rotate, and then the rotating column 25 rotates to drive the control ring 42 to rotate along the receiving ring 45, so that the rotation of the first toothed disc 43 cannot drive the second toothed disc 44 to rotate, and the guide bearing component 3 and the detection component 2 are disconnected.
