Description

Technical Field

[0001] The utility model relates to the technical field of steel structure detection, in particular to an ultrasonic non-destructive detection device for steel structure welds. Background Art

[0002] The steel pipelines tested by this ultrasonic nondestructive testing device are typically made of high-strength steel with excellent compressive and tensile properties. They are used to transport fluids and gases or serve as structural supports. The quality of these welds directly affects the overall strength and sealing of the pipelines, requiring ultrasonic nondestructive testing to accurately detect internal defects and ensure safe operation and structural stability.

[0003] Currently, weld inspections on steel structure pipelines rely on manual handheld inspection equipment. The inspection head contacts the surface of the structure, emits ultrasonic waves, and the spectrum presented by the received signal is used to understand the condition of the steel structure welds. This operation requires manual rotation of the steel structure pipeline, which is difficult for large pipeline structures. In addition, the pipeline is placed on the ground and is not stable, which affects the inspection accuracy.

[0004] Based on this, an ultrasonic nondestructive testing device for steel structure welds is proposed. Utility Model Content

[0021] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] See also Figure 1-Figure 3 , the utility model provides a technical solution:

[0023] An ultrasonic nondestructive testing device for steel structure welds includes a sleeve 1, which is telescopically connected to a plug rod 2. By adjusting the telescopic state of the plug rod 2, steel structure pipes of different lengths can be fixed, thereby improving the stability of the structure during the detection process. One end of the sleeve 1 is connected to a fixed column 3, and the fixed column 3 structure is in a vertical state. One side of the fixed column 3 is rotatably connected to a rotating plate 5, and the plug rod 2 is connected to a connecting frame 6, and the connecting frame 6 is connected to a sliding rod 7. A sleeve block 8 is slidably connected to the sliding rod 7, and a detection end 13 is connected to the sleeve block 8. The detection end 13 is an existing pipeline detection device that can emit ultrasonic waves. This structure is a prior art. One side of the rotating plate 5 is connected to a positioning mechanism for fixing the steel structure pipeline.

[0024] Specifically, such as Figure 1 As shown, a rotating column 4 is connected to one side of the rotating plate 5, and the rotating column 4 is rotatably connected to the fixed column 3. The rotating column 4 is vertically connected to one side of the rotating plate 5. The rotating column 4 is the rotating axis of the rotating plate 5, and the fixed column 3 can limit the position of the rotating column 4.

[0025] Specifically, such as Figure 1 As shown, a handle 12 is connected to one side of the rotating plate 5. The structure of the handle 12 can facilitate the operator to operate the rotating plate 5, thereby improving the convenience of rotating the steel structure pipeline. When rotating, the handle 12 needs to be operated to rotate circumferentially, that is, the handle 12 needs to be pulled along the circumferential direction.

[0026] Specifically, such as Figure 2 and Figure 3 As shown, the positioning mechanism includes an abutment plate 14, one end of the abutment plate 14 is connected to a bending plate 9, the bending plate 9 is slidably connected to one side of the rotating plate 5, and a clamping block 15 is connected to one side of the rotating plate 5. The clamping block 15 is rotatably connected to a threaded rod 11, and a bolt 16 is connected in the middle of the threaded rod 11. The bending plate 9 is threadedly connected to the threaded rod 11, and the threaded rod 11 is a bidirectional screw structure, that is, the upper half of the threaded rod 11 rotates forward, and the lower half rotates reversely. Therefore, when the bolt 16 is rotated, the two bending plates 9 connected thereto can be driven away from or closer to each other.

[0027] Specifically, such as Figure 3 As shown, a slider 17 is connected to one side of the bending plate 9, and a limiting bar 18 is connected to the rotating plate 5. The slider 17 is slidably connected between the limiting bars 18. By setting the limiting bars 18, the slider 17 structure is limited to improve the sliding stability of the slider 17 structure.

[0028] Specifically, such as Figure 3As shown, a threaded tube 10 is connected to the bending plate 9 , and the threaded tube 10 is threadedly connected to the threaded rod 11 . The threaded tube 10 is provided to improve the thread rotation cooperation effect between the bending plate 9 and the threaded rod 11 .

[0029] In summary, the ultrasonic non-destructive testing device for steel structure welds provided in this embodiment can be placed between the rotating plates 5 when it is necessary to perform weld inspection on the steel structure pipeline, and ensure that the abutment plate 14 is set in the pipeline. By rotating the bolt 16, the bending plates 9 can be moved away from each other, so that the abutment plate 14 is used to position the two ends of the pipeline, and the telescopic cooperation between the sleeve 1 and the insertion rod 2 is coordinated, so that the device can adapt to the pipeline of corresponding length for fixing. After fixing, the operator needs to move the sleeve block 8 to the weld, and the operating handle 12 structure drives the steel structure pipeline to rotate, and starts the detection end 13 to detect the uniformly rotating pipeline. Sleeve blocks 8 of different sizes can be selected to ensure that the detection end 13 can be close to the outer wall of the pipeline, thereby improving the detection accuracy. When the detection position needs to be changed, it is only necessary to move the sleeve block 8 to the corresponding weld, and then rotate the pipeline again to complete the detection.

[0030] For heavier pipes, lifting equipment can be used to assist in assembling the pipes onto the inspection device. However, manual operation cannot easily rotate heavy pipes, and problems such as poor rotation stability and pipe position deviation may occur during the rotation process. These problems will have a significant impact on pipeline inspection.

[0031] The rotation of the bolt 16 and the operation of the sleeve 1 and the insertion rod 2 during operation are all pretreatment steps before pipeline inspection. After the pipeline assembly is completed, the pipeline inspection can be carried out smoothly, which greatly improves the inspection accuracy. The use of separate operation steps between the pretreatment and inspection steps can avoid the pretreatment interfering with the inspection.

[0032] During the inspection, it is only necessary to place the pipeline on the device, and then it is only necessary to rotate the rotating plate 5 to realize synchronous inspection during the rotation of the pipeline, which greatly improves the inspection efficiency. Moreover, the pipeline can always rotate on the same axis during rotation, and the rotational stability of the pipeline structure is guaranteed during the inspection, which is an effect that cannot be guaranteed by manual rotation.

[0033] The above description of the embodiments is intended to enable those skilled in the art to implement or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not limited to the embodiments shown herein but is intended to conform to the widest scope consistent with the principles and novel features disclosed herein.
