Description

Technical Field

[0001] This utility model belongs to the field of building steel technology, specifically a self-adjusting detection guide rail for weld seams in building steel structures. Background Technology

[0002] In large-scale projects such as buildings, bridges, and industrial plants, steel structures are widely used due to their advantages such as high strength, large span, and convenient construction. As the core connection of steel structure components, the weld quality directly determines the overall load-bearing capacity, stability, and service life of the steel structure. If defects such as cracks, porosity, or incomplete penetration exist in the weld, they may cause structural safety hazards. Therefore, weld quality inspection is a critical link in the construction and operation and maintenance phases of steel structure engineering.

[0003] The existing moving mechanism of the inspection guide is mostly a combination of ordinary rollers and manual pushing or conventional motor drive. The moving accuracy is low and the stability is poor. It is difficult to move accurately and uniformly along the weld track, resulting in large errors in the inspection data. Before the weld inspection, the weld surface often needs to be ground. In the existing equipment, the grinding mechanism and the inspection mechanism are mostly designed separately. The grinding operation must be carried out separately before the inspection. The process is cumbersome and inefficient. Moreover, the grinding force cannot be adaptively adjusted according to the flatness of the weld surface, which can easily lead to over-grinding or incomplete grinding of the weld.

[0004] Therefore, this utility model provides an adaptive adjustment detection guide rail for weld seams in building steel structures. Utility Model Content

[0005] To address the shortcomings of existing technologies and solve the problem that existing equipment often features separate designs for grinding and inspection mechanisms, requiring separate grinding operations before inspection, which is cumbersome, inefficient, and the grinding intensity cannot be adaptively adjusted according to the weld surface flatness, easily leading to over-grinding or incomplete grinding of the weld, an adaptive adjustment inspection guide rail for welds in building steel structures is proposed.

[0006] The technical solution adopted by this utility model to solve its technical problem is as follows: A self-adjusting detection guide rail for weld seams in building steel structures, comprising a guide rail; two sets of guide rails are provided, with limiting plates fixedly installed on both sides of the two sets of guide rails; a support mechanism is provided on the top of the guide rail, and a moving component is provided on the inner wall of the support mechanism; a driving mechanism is provided on the top of the U-shaped frame, and a telescopic component is provided on the inner wall of the driving mechanism; a grinding mechanism is provided at the bottom of the telescopic component; detection components are provided on both sides of the U-shaped frame; the support mechanism includes a sliding plate, a reinforcing rib, and a U-shaped frame; the sliding plate is slidably installed on the surface of the guide rail, with the sides of the sliding plate fixedly installed to the reinforcing rib, and the top of the sliding plate fixedly installed to the U-shaped frame; the coordinated use of the sliding plate, reinforcing rib, and U-shaped frame can provide stable support for the moving component and the driving mechanism, ensuring their normal operation, and enabling movement through the driving of the moving component, thereby driving the detection probe to adaptively move to the weld seam.

[0007] Preferably, the moving component includes moving wheels and a stepper motor. Two sets of moving wheels are provided, and the two sets of moving wheels are rotatably installed on both sides of the inner wall of the skateboard. The side of the skateboard closest to the moving wheels is fixedly installed with the stepper motor, and the output end of the stepper motor is fixedly installed with the moving wheels. In this solution, the combined use of the moving wheels and the stepper motor can achieve the effect of driving the skateboard to move, so that the user can complete the detection through remote control without excessive human intervention.

[0008] Preferably, the driving mechanism includes a first bracket, a motor, and a transmission rod. The first bracket is fixedly installed on the top of the U-shaped frame, and the inner wall of the first bracket is fixedly installed with the motor. The output end of the motor is fixedly installed with the transmission rod. The transmission rod passes through the U-shaped frame to its bottom and is rotatably connected to the U-shaped frame. In this scheme, the coordinated use of the first bracket, the motor, and the transmission rod can provide the main driving force for the grinding mechanism, ensuring that it can rotate normally and perform grinding.

[0009] Preferably, the telescopic component includes a sliding groove and a cross-shaped insert. The sliding groove is formed on the inner wall of the transmission rod, and the cross-shaped insert is movably inserted into the inner wall of the transmission rod through the opening of the sliding groove. In this design, the sliding groove and the cross-shaped insert can rotate synchronously with the transmission rod and can freely extend and retract on the inner wall of the transmission rod, so that the grinding plate can be adaptively adjusted during grinding.

[0010] Preferably, the grinding mechanism includes a spring, a connecting plate, and a grinding plate. The spring is fixedly installed at the bottom of the transmission rod, and the connecting plate is fixedly installed at the bottom of the cross-shaped insert. The bottom of the connecting plate is threadedly connected to the grinding plate. In this scheme, the combined use of the spring, connecting plate, and grinding plate can grind the weld seam of the steel structure, thereby cleaning off the weld slag and debris, which can improve the detection accuracy.

[0011] Preferably, the detection assembly includes a second bracket and a detection probe. The second bracket is fixedly installed on both sides of the U-shaped frame, and the detection probe is fixedly installed on the side of the second bracket away from the U-shaped frame. In this scheme, the combined use of the second bracket and the detection probe can detect the steel structure, thereby detecting the welding strength of the weld and preventing subsequent safety accidents.

Furthermore, the moving components drive the inspection probe to adaptively move to the weld seam.

The output end of the motor 52 is fixedly installed with the transmission rod 53. The transmission rod 53 passes through the U-shaped frame 33 to its bottom, and the transmission rod 53 is rotatably connected to the U-shaped frame 33. The telescopic component 6 includes a sliding groove 61 and a cross-shaped insert 62. The sliding groove 61 is formed on the inner wall of the transmission rod 53, and the cross-shaped insert 62 passes through the sliding groove. The opening of 61 is inserted into the inner wall of the transmission rod 53. The grinding mechanism 7 includes a spring 71, a connecting plate 72 and a grinding plate 73. The spring 71 is fixedly installed at the bottom of the transmission rod 53. The connecting plate 72 is fixedly installed at the bottom of the cross-shaped insert 62.

The second bracket 81 is fixedly installed on both sides of the U-shaped frame 33. The detection probe 82 is fixedly installed on the side of the second bracket 81 away from the U-shaped frame 33.

[0026] like Figures 1 to 5As shown, the combined use of the slide plate 31, reinforcing rib 32, and U-shaped frame 33 provides stable support for the moving component 4 and the drive mechanism 5, ensuring their normal operation. The moving component 4 drives the movement, enabling the detection probe 82 to adaptively move to the weld.

[0027] Working principle: During operation, the guide rail 1 is first installed on one side of the steel structure. Then, the stepper motor 42 is started, driving the moving wheel 41 to rotate. The rotation of the moving wheel 41 moves on the surface of the guide rail 1, driving the slide plate 31 and the reinforcing rib 32 to translate on the surface of the guide rail 1. When the slide plate 31 translates, it drives the U-shaped frame 33 to move synchronously. The movement of the U-shaped frame 33 drives the grinding plate 73 and the detection probe 82 to move. Before starting the detection, the user can start the motor 52, which drives the transmission rod 53 to rotate. The rotation of the transmission rod 53 drives the cross-shaped insert rod. The cross-shaped insert 62 rotates, and the rotation of the cross-shaped insert 62 drives the grinding plate 73 to rotate synchronously through the connecting plate 72. When the grinding plate 73 rotates, it continuously grinds the surface of the steel structure. When the surface of the steel structure is uneven, the spring 71 can push the connecting plate 72 and the grinding plate 73 to make them fit tightly with the steel structure, avoiding gaps that would lead to insufficient grinding. Then, the user can start the detection probe 82 to inspect the ground steel structure. Since the rust, slag, spatter, and oxide scale on the surface of the steel structure weld are ground off, the detection accuracy of the detection probe 82 will be significantly improved.
