Description

Technical Field

[0001] The invention relates to the technical field of cylinder joint weld detection, in particular to cylinder joint weld detection equipment. Background Art

[0002] Cylinder weld inspection refers to a series of inspection activities on the welds at the connection points of adjacent cylinders in circular or nearly circular structures such as pipelines or pressure vessels. These inspections are aimed at discovering defects in the welds, such as cracks, pores and slag inclusions, and evaluating the overall quality of the welds. Inspections usually include visual inspection, dimensional measurement, and the use of non-destructive testing technology to evaluate the internal integrity of the welds. Through these inspection methods, it can be ensured that the welds meet the design and safety standards and prevent potential leakage or structural failure risks. Cylinder weld inspection is mainly to ensure welding quality, prevent product failure or accidents caused by weld defects, and ensure the safety and reliability of the structure.

[0003] According to the announcement number CN117630171A, a pipe weld flaw detection device is disclosed, including a base, a hollow vertical plate is fixedly connected to the upper end of the base, a probe is connected to the hollow vertical plate, an inner cavity is opened inside the hollow vertical plate, an annular hole communicating with the outside is opened on the inner ring wall of the inner cavity, a moving ring plate is rotatably connected inside the inner cavity, the upper end of the probe sequentially moves through the annular hole and the moving ring plate and is fixedly connected to a connecting plate, a pair of elastic telescopic columns are fixedly connected between the connecting plate and the outer end of the moving ring plate, the elastic telescopic column includes a telescopic rod and a tension spring, the telescopic rod is fixedly connected between the connecting plate and the moving ring plate, the tension spring is sleeved on the outer side of the telescopic rod, and its two ends are respectively abutted on the connecting plate and the moving ring plate, a positioning rod and an electric rotating shaft are fixedly connected to the rear inner wall of the inner cavity, one end of a pull rope is also fixedly connected to the outer end of the moving ring plate, the other end of the pull rope sequentially bypasses the outer end of the moving ring plate and the positioning rod and is fixedly connected to the outer end of the electric rotating shaft, and the connection position of the pull rope and the moving ring plate is located between the connecting plate and the rear inner wall of the inner cavity.

[0004] By adopting the above technical scheme, the application realizes an elastically movable connection for the probe on the moving ring plate by setting an elastic telescopic column. When the moving ring plate drives the probe to rotate 360°, on the one hand, all-round detection of the annular weld is realized, and the probe and the weld surface are continuously kept in close contact, which effectively improves the accuracy of the detection. On the other hand, the probe with elastic movement function can adapt to pipes of different diameters, so that the application has a large scope of application, and in the process of installing pipes, the placement position of the pipe has a large allowable range. Even if the pipe and the hollow vertical plate are not coaxial, the probe can be moved inward and outward according to the position of the pipe during the detection process, and always keep close contact with the weld to achieve accurate detection. However, in the above technical scheme, when using the device to detect the weld of the cylinder section, since the weld of the cylinder section is divided into a longitudinal weld and a circumferential weld, it is easy to have more troubles when using the device to detect the longitudinal weld, which is not convenient for the cylinder section of the longitudinal weld to be detected.

By setting the ultrasonic probe 12, the principle of ultrasonic probe 12 detecting welds is based on the propagation characteristics of ultrasonic waves in materials. When the ultrasonic probe 12 emits high-frequency sound waves, these sound waves will enter the weld being detected. If there are defects inside the weld, such as cracks, pores, incomplete fusion or incomplete penetration, the ultrasonic wave will be reflected, refracted or scattered when encountering these defects. By analyzing the time delay, amplitude and morphological changes of these electrical signals, the position, size and nature of the internal defects of the weld can be inferred.

[0024] The specific implementation method of this embodiment is as follows: first, the power supply of the forward and reverse motor 402 is turned on so that it can be in a stable power-on state. When it is necessary to assist the detected cylinder segment, the staff turns on the forward and reverse motor 402.

Example

[0025] See also Figure 1-6The specific implementation method of this embodiment is as follows: first, the staff transports the device to a suitable use position, and then turns on the power of the first rotating motor 306, the forward and reverse motor 402, the ultrasonic probe 12 and the second rotating motor 13, so that they can be in a stable power-on state. When the staff detects the barrel section of the longitudinal weld, the staff turns on the ultrasonic probe 12 for detection and turns on the forward and reverse motor 402 at the same time. After the forward and reverse motor 402 is turned on, it can generate power rotation. The rotation of the forward and reverse motor 402 can drive the bidirectional threaded rod 403 to rotate. Under the action of the rotation of the bidirectional threaded rod 403, the drive surface The two moving blocks 404 on the upper surface move, and during the movement of the moving blocks 404, the two moving frames 405 at the bottom can be driven to move, until the two moving frames 405 drive the internal rollers 406 to move around the barrel section, so as to limit the barrel section to a certain extent, and then immediately start the first rotating motor 306, and the first rotating motor 306 starts to generate power rotation after being turned on. The rotation of the first rotating motor 306 can drive the first rotating shaft 307 to rotate, and at the same time, during the rotation of the first rotating shaft 307, it will drive and circulate with the first driving gear 308, and the effect of the rotation of the first driving gear 308 Under the action of the present invention, the transmission gear 309 on the surface of the driving roller 303 is rotated. During the rotation of the transmission gear 309, the roller 303 inside can be driven to rotate. When one roller 303 rotates, the conveying cylinder 302 on the surface and the roller 303 at the other end of the conveying cylinder 302 can be driven to rotate, thereby driving a rotating gear 304 to rotate. At the same time, when the rotating gear 304 rotates, it can drive the rack 305 to move, and then drive the remaining rotating gears 304 and the conveying cylinder 302 to rotate. Under the action of the rotation of multiple conveying cylinders 302, the cylinder sections on the driving surface can be moved, so that The cylinder section is pushed into the interior of the detection frame 2 for detection. At the same time, the roller 406 can also be easily rotated, thereby assisting the cylinder section to be stably transported, so as to facilitate the detection equipment to detect the cylinder section of the longitudinal weld. When the cylinder section of the annular weld needs to be detected, the staff uses the same method to transport the annular weld of the cylinder section to the interior of the detection frame 2, and then turns on the second rotating motor 13. After the second rotating motor 13 is turned on, it can drive the second rotating shaft 14 and the second driving gear 15 to rotate, thereby driving the gear ring 11 and the ultrasonic probe 12 to rotate, and then it can rotate around the annular weld for detection.
