Description

Technical Field

[0001] The invention relates to a steel beam welding technology, and in particular to an intelligent welding system and a welding method for steel beam accessories. Background Art

[0002] Structural steel beams are widely used in large-span, ultra-high or ultra-heavy buildings such as factories, stadiums, and super-high-rise buildings due to their high strength, light weight, and good plasticity. There are usually many accessories welded on structural steel beams to meet the needs of steel beam connection and steel beam structure reinforcement. These accessories are located on multiple sides of the structural steel beam. In order to ensure that the welding position of each accessory can be at the best angle during welding, the structural steel beam needs to be flipped several times during the accessory welding process. At present, the flipping work is mainly achieved by manual cooperation with the flipping mode of the crane and tooling. This flipping mode is time-consuming and labor-intensive, with poor safety, and can no longer meet the current needs of automated and large-scale production of structural steel beams.

[0003] The Chinese invention patent with publication number CN114669926B discloses an intelligent welding system for steel beam accessories. In this intelligent welding system for steel beam accessories, after the accessories required for welding of the steel beam are manually placed on the placement platform in sequence, the identification device identifies and memorizes the accessories in sequence. The assembly robot finds the accessories from the identified and memorized accessories in sequence according to the welding sequence, picks them up and places them to the designated position of the steel beam on the positioner, and the welding robot spot welds each accessory in real time. During the process of picking up, placing, and spot welding all accessories, the positioner cooperates to rotate and displace the construction steel beam until all accessories are spot welded. The welding process is also coordinated by the rotation and displacement of the positioner. In this way, the present invention realizes the full automation of steel beam accessory welding as a whole, reduces human participation, improves operation safety and efficiency, and ensures the final welding quality.

[0004] When the existing equipment is in use, rust, oil, dust and other impurities on the surface of the steel beam are not removed, which makes it easy for defects such as pores and slag inclusions to appear on the surface of the steel beam during subsequent processing. At the same time, during the welding process, the direction cannot be correctly adjusted, resulting in blind spots and dead angles in the welding, resulting in defects in the weld, affecting the subsequent normal use. Therefore, an intelligent welding system and welding method for steel beam accessories have been developed. Summary of the invention

[0048] When the steel beam is placed on the pretreatment component 4, the two sides of the steel beam are first limited by two positioning plates 49. When the steel beam slowly descends, the two conical cylinders 481 are pushed to move to both sides along the limit rod 482. At the same time, the two conical cylinders 481 are supported by the third elastic member 483, wherein the third elastic member 483 is an elastic component such as a spring, thereby preliminarily limiting the outer surface of the steel beam.

[0049] At the same time, the outer surface of the positioning plate 49 is provided with a component having a grinding effect, such as a grinding plate, so that when the pretreatment component 4 is moved as a whole, the outer surface of the steel beam can be cleaned.

[0050] Furthermore, telescopic rods 42 are provided at the upper end of the bottom plate 41 and on both sides of the slide groove 411, and a protective plate 43 is provided at the upper end of the telescopic rod 42.

[0052] The positioning rod 441 is restricted by the positioning groove 44 on the protective plate 43, so that the positioning rod 441 is always in a stable state when moving, thereby ensuring that no deviation occurs during the subsequent positioning process.

[0054] Specifically, the power member 47 is a device with power output such as a motor, and is connected to an external control device. When the power member 47 is started, it synchronously drives the disc 46 arranged at its output end to rotate. Since a rotating rod 461 is rotatably installed on the outer surface of the disc 46, when the rotating rod 461 moves, the positioning rod 441 can be driven to move.

When the extrusion plate 452 is subjected to force and fits against the inner wall of the steel beam, the extrusion plate 452 is supported by the second elastic member 451, thereby ensuring that the steel beam is tightly supported.

[0057] At the same time, the outer surface of the extrusion plate 452 is provided with a component having a grinding effect, such as a grinding plate, so that the extrusion plate 452 can clean the inner wall of the steel beam.

The inner wall of the ring gear plate 25 meshes with the outer surface of the transmission gear 23 .

[0060] In this embodiment, the driving member 22 is a device with power output such as a motor, and is connected to an external control device. When the driving member 22 is started, it synchronously drives the transmission gear 23 arranged at its output end to rotate. Since the outer surface of the transmission gear 23 is meshed with the inner wall of the annular gear plate 25, the annular gear plate 25 is rotated and fixed by the support plate 24, thereby ensuring that the annular gear plate 25 will not be disturbed when rotating.

[0061] Furthermore, the outer surface of the ring gear plate 25 is symmetrically provided with extension blocks 26 , the ends of the extension blocks 26 are provided with guide blocks 27 , and one end of the guide block 27 away from the extension block 26 is provided with a guide groove 271 .

[0063] Furthermore, the positioning assembly 3 is assembled on the upper end of the flip assembly 2, and the steel beam is fixed by the positioning assembly 3. The positioning assembly 3 includes an adjustment block 31 slidably connected to the inner wall of the guide groove 271, and both ends of the adjustment block 31 are rotatably mounted with adjustment rods 32. The end of the adjustment rod 32 away from the adjustment block 31 is rotatably mounted with a rotation block 34, and the two rotation blocks 34 are rotatably connected by a telescopic member 38.

[0064] In this embodiment, the telescopic member 38 is a device with a telescopic function such as an electric telescopic rod, and is connected to an external control device. When the telescopic member 38 is started, it synchronously drives the rotating block 34 to move, and then can clamp the outer surface of the steel beam, so that when the steel beam is rotated, it will not fall off.

[0065] Furthermore, a movable rod 33 is rotatably mounted on the outer surface of the adjustment rod 32, and a push rod 35 is disposed at one end of the rotating block 34, and the end of the push rod 35 penetrates and extends to the other end of the rotating block 34, and a limiting groove 351 is provided on one side of the push rod 35, and the inner wall of the limiting groove 351 is slidably connected to the end of the movable rod 33.

[0067] The control device can select a single-chip microcomputer as the control end. In this embodiment, the single-chip microcomputer is a typical embedded microcontroller (Micro controller Unit), which is composed of an arithmetic unit, a controller, a memory, an input and output device, etc., and is equivalent to a microcomputer. Compared with the general-purpose microprocessor used in personal computers, it emphasizes self-supply (no external hardware) and cost saving. Its biggest advantage is that it is small in size and can be placed inside the instrument, but has a small storage capacity, a simple input and output interface, and low functional consumption.
