Description

Technical Field

[0001] The present invention relates to the technical field of pipeline detection, and particularly relates to a non-destructive detection device and method for pressure pipeline detection. Background Art

[0002] Ultrasonic testing is one of the commonly used methods in pipeline detection. Its principle is to utilize the characteristics of ultrasonic waves propagating in materials to detect pipeline defects. Through the sound waves sent by an ultrasonic detector, internal defects in the pipeline will be reflected back, thereby obtaining the degree and location of the pipeline defects.

[0003] Chinese Patent CN109519712B discloses a high-precision fault monitoring device, which includes an upper housing and a lower housing. A first leak stoppage groove and a second leak stoppage groove are respectively recessed in the upper housing and the lower housing. The first leak stoppage groove and the second leak stoppage groove are respectively connected to a first leak stoppage device and a second leak stoppage device. A driving motor is provided above the upper housing. The driving motor drives a first roller below it through a motor shaft, whereby the upper housing and the lower housing move synchronously. A vibration sensor is also provided below the driving motor. Ultrasonic flaw detectors are respectively provided in the upper housing and the lower housing. During use, the vibration sensor is used to monitor the leakage fault of the gas pipeline, and then the ultrasonic flaw detector is used to detect the leakage point. Then, the first leak stoppage device and the second leak stoppage device are used to perform emergency repair on the gas pipeline. By relying on the effect that the emergency repair agent can quickly solidify, the function of emergently blocking the leakage point of the gas pipeline can be achieved, and the function of high-precision monitoring of the leakage fault of the gas pipeline can be achieved.

[0004] However, the structure disclosed in the above patent cannot be installed on an already laid continuous pipeline for use. At the same time, it cannot adapt to pipelines with different outer diameter sizes for detection. In addition, the above structure cannot cross the flange between pipelines during detection, which is not conducive to practical use.

[0005] Based on this, the present invention designs a non-destructive detection device and method for pressure pipeline detection to solve the above problems. Summary of the Invention

Then the second translation drive assembly is adjusted to the combined state, and then continue the detection from repeating Step 2.

[0029] The present invention has the following technical effects:

[0030] The present invention opens the spliced gear assembly of the assembled detection component, then slews the spliced gear assembly outside the pipeline, and then adjusts the spliced gear assembly to the combined state.

Then, the rotation drive component drives the spliced gear assembly to rotate, the spliced gear assembly drives the adjusting component to rotate along the pipeline, the adjusting component drives the moving component to rotate along the pipeline, the moving component drives the adaptive component to rotate along the pipeline, and the adaptive component drives the ultrasonic probe to rotate forward along the pipeline for one full circle of detection. Then, the first translation drive assembly and the second translation drive assembly drive the ultrasonic probe to move to the next detection position, and the ultrasonic probe rotates backward for one full circle of detection. Then, the ultrasonic probe moves to the next detection position, the ultrasonic probe rotates forward along the pipeline for one full circle of detection, the ultrasonic probe moves to the next detection position, and the ultrasonic probe rotates backward for one full circle of detection. Repeating the above actions realizes continuous non-destructive testing of the pipeline, which is beneficial for practical use; when the first translation drive assembly needs to cross the flange, the first translation drive assembly is in the open state, the second translation drive assembly is in the combined state, and the second translation drive assembly drives; when the ultrasonic probe needs to cross the flange, the first translation drive assembly is in the combined state, the moving component drives the ultrasonic probe to be located outside the outer edge of the flange, the second translation drive assembly is in the combined state, and the second translation drive assembly drives; when the second translation drive assembly needs to cross the flange, the second translation drive assembly opens, the first translation drive assembly is in the combined state, and the first translation drive assembly drives.

The other end of the first arc gear 54 is in contact with the other end of the second arc gear 56. Then, hook the hook 520 with the hanging rod 519 to make the first arc gear 54 and the second arc gear 56 in a combined state. The first translation drive assembly 2 and the second translation drive assembly 4 are combined to be in contact with the outer wall of the pipeline 3. The telescopic end of the electric push rod 513 of the moving component extends. The electric push rod 513 drives the mounting frame 515 to move, and the guide rod 514 conducts guiding. The mounting frame 515 drives the ultrasonic probe 517 to move to the innermost end. The fixing part 512 of the rotation adjustment component is separated from the sliding plate 510. Slide the sliding plate 510 along the mounting sleeve 511. The sliding plate 510 drives the mounting frame 515 to move towards the pipeline 3. The mounting frame 515 drives the ultrasonic probe 517 to contact the outer wall of the pipeline 3. Adjust the ultrasonic probe 517 to be in close contact with the outer wall of the pipeline 3, and the spring 516 is in a stretched state.

Then, rotate the third motor 52 of the rotation drive component to drive the gear ring 57 to rotate. The gear ring 57 drives a complete set of gear rings formed by the combination of the first arc gear 54 and the second arc gear 56 of the spliced gear assembly to rotate.

The electric push rod 513 and the guide rod 514 drive the mounting frame 515 to rotate. The mounting frame 515 drives the spring 516 and the sliding plate 518 to rotate. The sliding plate 518 and the spring 516 drive the ultrasonic probe 517 to rotate along the pipeline 3, driving the ultrasonic probe 517 to rotate forward along the pipeline 3 for a full circle of detection. Then, the first translation drive assembly 2 and the second translation drive assembly 4 drive the ultrasonic probe 517 to move to the next detection position.

The mounting bracket 515 drives the ultrasonic probe 517 to move away from the pipeline 3 to the outside of the outer edge of the flange 6. The distance from the ultrasonic probe 517 to the side wall of the pipeline 3 to the center axis of the pipeline 3 is greater than the distance from the outer edge of the flange 6 to the center axis of the pipeline 3. After the second translation drive component 4 drives the ultrasonic probe 517 to move across the flange 6, the telescopic end of the electric push rod 513 of the moving component extends, the electric push rod 513 drives the mounting bracket 515 to move, and the guide rod 514 guides.
