Description

Technical Field

[0001] The utility model relates to the technical field of steel structure flaw detection device equipment, in particular to an ultrasonic flaw detection device for steel structure identification. Background Art

[0002] Ultrasonic testing is a nondestructive testing method that uses the properties of ultrasonic waves propagating through materials to detect defects and damage. Ultrasonic testing boasts high sensitivity, ease of operation, and a wide range of applications, making it widely used in aviation, aerospace, automotive, petrochemical, metallurgy, construction, and other fields. The principle of ultrasonic testing is that a transmitter generates high-frequency ultrasonic waves and transmits them into the material being tested. When the ultrasonic waves encounter defects or damage, they are reflected, refracted, or diffracted. The receiver receives these signals, processes them, and forms an image, thereby determining whether defects are present within the material.

[0003] In the process of implementing flaw detection operations on existing steel pipe structures, in order to maintain the stability of the steel pipe structure, the steel pipe structure needs to be positioned first. The existing positioning methods mostly use manual picking up of steel pipes and placing them in the positioning structure. However, the steel pipes themselves have a certain weight. If ultrasonic flaw detection operations need to be performed on multiple steel pipes, the workload of manually handling the steel pipes is large. The manual operation of the steel pipe structure in the positioning structure to perform material feeding and unloading operations takes a long time, which in turn reduces the efficiency of the flaw detection of the steel pipe structure.

DETAILED DESCRIPTION

[0020] The following will be combined with the 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.

[0021] Example: Reference Figure 1-4 The ultrasonic flaw detection device for steel structure identification shown in the figure includes a ring-shaped base 1 and an ultrasonic probe 2 disposed above the base 1. The base 1 is provided with a housing 3 that can accommodate a steel pipe structure. The base 1 is also provided with a plurality of clamping rollers 1 4 and 2 5 arranged equidistantly along a circumferential trajectory. Each clamping roller 1 4 is located directly above clamping roller 2 5. Each set of clamping rollers 1 4 and 2 5 can move along the radius of the housing 3 until the clamping rollers 1 4 and 2 5 abut the surface of the steel pipe structure. The clamping rollers 1 4 and 2 5 can perform positioning operations on the steel pipe structure, maintaining its stability so that the steel pipe structure can stably fall into the housing 3 for flaw detection operations.

[0022] Clamping rollers 1 4 and 2 5, located in the same linear direction, are connected by a linkage frame 6. Linkage frame 6 is equipped with a drive structure that controls the synchronous rotation of clamping rollers 1 4 and 2 5. As clamping rollers 1 4 and 2 5 rotate, steel pipes can be placed in and removed from the receiving sleeve 3, performing feeding and unloading operations.

[0023] Each linkage frame 6 is equipped with a support column 61 at its bottom end. The base 1 is provided with multiple guide channels 11 along a circular path to accommodate the sliding movement of the support columns 61. A second drive cylinder 62 is mounted on the outside of the base 1. The portion of the support column 61 exposed below the guide channels 11 is connected to the output end of the second drive cylinder 62. The second drive cylinder 62 controls the sliding movement of the support column 61 along the guide channels 11, thereby driving multiple linkage frames 6, clamping rollers 1 4, and clamping rollers 2 5 to synchronously move toward and away from the steel pipe structure. This ensures that the first and second clamping rollers 4 and 5 simultaneously clamp and move away from the steel pipe structure, achieving the purpose of automatically positioning the steel pipe structure.

[0024] The drive structure includes a first roller 7 and a second roller 8 mounted on the central axis of clamping roller 1 4 and clamping roller 2 5, respectively. The first and second rollers 7 and 8 are connected by a linkage belt 9. A motor 10 is mounted on the outside of the linkage frame 6 to control the rotation of the second roller 8. The power generated by the operation of the motor 10 rotates the second roller 2 8. Under the connecting force of the linkage belt 9, the first and second rollers 7 and 8 rotate synchronously, thereby driving the synchronous rotation of the first and second rollers 4 and 5.

[0025] The arrangement of multiple sets of clamping rollers 1 (4) and 2 (5) allows for rapid placement and removal of steel pipe structures, enabling rapid and stable feeding and unloading of steel pipes. This reduces the time required for manual handling and alignment operations, improving efficiency during flaw detection inspections of steel pipe structures.

[0026] The base 1 is provided with an extension arm 12, and the top of the extension arm 12 is provided with a top plate 13 parallel to the base 1. The ultrasonic probe 2 is located below the top plate 13, and the ultrasonic probe 2 is provided with a movable arm 17. Before and after the ultrasonic flaw detection work is carried out on the steel pipe, the ultrasonic probe 2 and the movable arm 17 can move along the radial direction of the top plate 13, leaving space for the steel pipe structure to be smoothly placed in and out of the accommodating sleeve 3.

[0027] A drive shaft 14 is located at the center of the top plate 13. A motor 2 15 is mounted on the top plate 13 to control the rotation of the drive shaft 14. An L-shaped rotating arm 16 is located at the bottom end of the drive shaft 14. A movable arm 17 faces one side of the rotating arm 16. A drive cylinder 18 is mounted on the rotating arm 16. The output end of the drive cylinder 18 extends through the rotating arm 16 and connects to the movable arm 17. Before and after ultrasonic flaw detection on the steel pipe, the output force of the drive cylinder 18 forces the movable arm 17 away from the rotating arm 16, leaving space for the steel pipe to be smoothly inserted and removed from the housing 3, preventing the ultrasonic probe 2 from obstructing the steel pipe structure. During flaw detection, the drive cylinder 18 drives the movable arm 17 and the ultrasonic probe 2 to move directly above the steel pipe structure. The operation of the motor 2 15, coupled with the rotating arm 16, causes the ultrasonic probe 2 to rotate along its annular end to perform the inspection.

[0028] like Figure 3 As shown, to reduce frictional resistance during the placement and removal of the steel pipe structure from the housing 3, the inner surface of the housing 3 is provided with multiple raised portions projecting toward its central axis. These raised portions are evenly spaced along a circular trajectory. This improves the smoothness of the pipe's movement as the first and second clamping rollers 4 and 5 control the raising and lowering of the steel pipe structure.

[0029] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
