Description

Technical Field

[0001] This utility model relates to the field of pipeline welds, specifically to a digital non-destructive testing device for pipeline welds using X-rays. Background Technology

[0002] Pipeline welds are the welded areas that connect two sections of pipeline. They are formed through processes such as fusion welding and pressure welding. They are the most critical links in a pipeline system that are most prone to defects. Welds must withstand the pressure, temperature, and corrosiveness of the medium transported by the pipeline. Their quality directly affects the safety, sealing, and service life of the pipeline. Pipeline weld X-ray digital non-destructive testing equipment uses X-rays to penetrate the weld and uses digital imaging technology to detect internal defects.

[0003] Existing X-ray digital non-destructive testing equipment suffers from several drawbacks during use. The reliance on a single X-ray for flaw detection can lead to missed shallow cracks in pipe welds, and the difficulty in determining defect depth with X-rays can cause deviations in repair plans. Furthermore, long-term use requires multiple X-ray examinations and supplementary testing methods for suspected defects, increasing the testing cycle and reducing efficiency.

[0004] Therefore, it is necessary to invent a digital non-destructive testing device for pipe welds using X-rays to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a digital X-ray non-destructive testing device for pipeline welds. This device utilizes an X-ray machine, a digital detector, an ultrasonic flaw detector, a first outer detection ring, a first detection gear ring, an X-ray probe, and an ultrasonic probe to achieve multi-modal non-destructive testing capabilities. This design avoids the difficulty in detecting area-type defects such as incomplete penetration during X-ray testing, allowing for precise location of defect depth and compensating for the ambiguity of X-ray defect characterization. Furthermore, the synergistic effect of ultrasonic testing and X-ray detection provides broader coverage of pipeline weld defects. This multi-modal non-destructive testing capability also reduces repetitive testing procedures and improves testing efficiency. This addresses the problems of existing digital X-ray non-destructive testing devices, where single-ray testing can lead to missed shallow cracks in pipeline welds, difficulty in determining defect depth, and deviations in repair plans. Moreover, long-term use requires multiple X-ray examinations and auxiliary testing methods for suspected defects, increasing the testing cycle and reducing efficiency.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a digital non-destructive testing device for pipeline welds using X-rays, comprising a digital gantry inspection frame and a main body for pipeline weld flaw detection;

[0007] An X-ray machine is fixedly installed on the outer left side of a digital gantry inspection frame to provide X-rays. A digital detector is fixedly installed above the X-ray machine. A first outer detection ring is fixedly installed in front of the digital gantry inspection frame. An inner sliding groove is opened on the outside of the first outer detection ring. An inner slider is slidably connected inside the inner sliding groove. A first detection toothed ring is fixedly installed on the outside of the inner slider.

[0008] The external fixing blocks are all fixedly set on the outside of the first detection gear ring for connecting and installing the telescopic cylinder. The front end of the telescopic cylinder is fixedly installed with a connecting plate, and the X-ray probe is fixedly installed inside the connecting plate.

[0009] An ultrasonic flaw detector is fixedly installed on the outer right side of the digital gantry inspection frame to provide ultrasonic flaw detection. A wireless drive controller is fixedly installed above the ultrasonic flaw detector. A second outer detection ring is fixedly installed at the rear of the digital gantry inspection frame. A second detection toothed ring is slidably connected to the outside of the second outer detection ring. An ultrasonic probe is fixedly installed inside the second detection toothed ring. A pusher seat is slidably installed at the bottom of the digital gantry inspection frame.

[0010] Preferably, the first detection tooth ring is slidably connected to the first outer detection ring, and the inner sliding groove is used in conjunction with the inner slider.

[0011] Preferably, the number of X-ray probes is set to four, and the four X-ray probes are arranged in a ring array on the first detection gear ring.

[0012] Preferably, a drive motor is fixedly installed above the digital gantry inspection frame, and a drive gear is rotatably connected to the output end of the drive motor. The drive gear meshes with a first detection gear ring, and the tooth direction of the drive gear is opposite to that of the first detection gear ring.

[0013] Preferably, an electric slide rail is fixedly installed above the pusher seat, and an electric sliding sleeve is slidably connected to the outside of the electric slide rail. The outside of the electric sliding sleeve is fixedly connected to the bottom of the digital gantry inspection frame.

[0014] Preferably, each of the push bases is rotatably connected to a push roller, and positioning plates are fixedly installed on both sides of the push base. A positioning screw is threaded through the top of the positioning plate.

[0015] The technical effects and advantages provided by this utility model in the above technical solution are as follows:

[0016] 1. This utility model is equipped with an X-ray machine, a digital detector, an ultrasonic flaw detector, a first outer detection ring, a first detection gear ring, an X-ray probe, and an ultrasonic probe. When using this X-ray digital non-destructive testing device, the first detection gear ring, located outside the pipe weld, drives the X-ray probe to rotate around the pipe weld. X-rays are emitted by the X-ray machine and the X-ray probe for flaw detection. Then, the entire digital gantry inspection frame moves forward, allowing the second outer detection ring to be placed outside the pipe weld again. Similarly, the second detection gear ring drives the second detection gear ring to rotate, thus performing secondary flaw detection. This ultrasonic flaw detection supplements the limitations of X-ray flaw detection, forming a multi-modal non-destructive testing capability for this X-ray digital non-destructive testing device. This design can also avoid the occurrence of difficult-to-detect area defects such as incomplete penetration by X-ray flaw detection, accurately locate the defect depth, and make up for the ambiguity of X-ray in defect characterization. Moreover, ultrasonic flaw detection and X-ray form an internal and external synergistic detection, covering a wider range of pipe weld defects. At the same time, this multi-modal non-destructive testing capability can reduce repeated inspection procedures and improve inspection efficiency.

[0017] 2. This utility model includes an X-ray machine, a digital detector, an X-ray probe, an ultrasonic flaw detector, a wireless drive controller, and an ultrasonic probe. When using this X-ray digital non-destructive testing device, since the X-ray machine, digital detector, X-ray probe, ultrasonic flaw detector, and ultrasonic probe are all electrically connected to the wireless drive controller, external operators can remotely connect to the wireless drive controller to control the X-ray digital non-destructive testing device to perform flaw detection on pipe welds. This avoids the problem of personnel getting too close and being affected by X-rays and ultrasound. Such remote operation keeps the inspection personnel away from the radiation source, avoiding long-term cumulative radiation risks, and also enables the X-ray digital non-destructive testing device to achieve a triple improvement in safety, efficiency, and flexibility.

[0027] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0028] This utility model provides, for example Figure 1-6 The illustrated X-ray digital non-destructive testing device for pipeline welds includes a digital gantry inspection frame 1, which is the main body for pipeline weld flaw detection.

[0029] X-ray machine 2 is fixedly installed on the outer left side of digital gantry inspection frame 1 to provide X-rays. A digital detector 3 is fixedly installed above the X-ray machine 2. A first outer detector ring 4 is fixedly installed in front of the digital gantry inspection frame 1. An inner sliding groove 5 is opened on the outside of the first outer detector ring 4. An inner slider 6 is slidably connected inside the inner sliding groove 5. A first detector tooth ring 7 is fixedly installed on the outside of the inner slider 6.

[0030] The external fixing blocks 8 are all fixedly set on the outside of the first detection gear ring 7, and are used to connect and install the telescopic cylinder 9. The front end of the telescopic cylinder 9 is fixedly installed with a connecting plate 10, and the X-ray probe 11 is fixedly installed inside the connecting plate 10.

[0031] An ultrasonic flaw detector 14 is fixedly installed on the outer right side of the digital gantry inspection frame 1 to provide ultrasonic flaw detection. A wireless drive controller 15 is fixedly installed above the ultrasonic flaw detector 14. A second outer detection ring 16 is fixedly installed at the rear of the digital gantry inspection frame 1. A second detection gear ring 17 is slidably connected to the outside of the second outer detection ring 16. An ultrasonic probe 18 is fixedly installed inside the second detection gear ring 17. A pusher seat 19 is slidably installed at the bottom of the digital gantry inspection frame 1. The first detection gear ring 7 drives the X-ray probe 11 to rotate around the pipe weld, and X-rays are emitted by the X-ray machine 2 and the X-ray probe 11 to perform flaw detection. Then, the entire digital gantry inspection frame 1 moves forward so that the second outer detection ring 16 is fitted onto the outside of the pipe weld again. Similarly, the second detection gear ring 17 drives the second detection gear ring 17 to rotate, thereby performing secondary flaw detection.

[0032] like Figure 1 , Figure 2 , Figure 3 and Figure 6 As shown, the first detection toothed ring 7 is slidably connected to the first outer detection ring 4, and the inner sliding groove 5 and the inner sliding block 6 work together. The first detection toothed ring 7 drives the X-ray probe 11 to rotate around the pipe weld through the inner sliding groove 5 and the inner sliding block 6. The number of X-ray probes 11 is set to four, and the four X-ray probes 11 are arranged in a ring array on the first detection toothed ring 7. The simultaneous detection of the four groups of X-ray probes 11 improves the detection efficiency of the pipe weld.

[0033] like Figure 1 , Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, a drive motor 12 is fixedly installed above the digital gantry inspection frame 1. A drive gear 13 is rotatably connected to the output end of the drive motor 12. The drive gear 13 meshes with the first detection gear ring 7. The teeth of the drive gear 13 and the first detection gear ring 7 are opposite in direction. The meshing and rotation of the drive gear 13 and the first detection gear ring 7 drives the X-ray probe 11 to rotate at a uniform speed, completing the flaw detection work. An electric slide rail 20 is fixedly installed above the pusher seat 19. An electric sliding sleeve 2 is slidably connected to the outside of the electric slide rail 20. 1. The electric sliding sleeve 21 is fixedly connected to the bottom of the digital gantry inspection frame 1. The electric sliding sleeve 21 and the electric sliding rail 20 drive the entire digital gantry inspection frame 1 to move forward so that the second outer detection ring 16 is fitted onto the outside of the pipe weld. The outer side of the push seat 19 is rotatably connected with push rollers 22. Positioning plates 23 are fixedly installed on both sides of the outer side of the push seat 19. Positioning screws 24 are threaded through the top of the positioning plates 23. The push rollers 22 facilitate the direct push of the device to different pipes to perform pipe weld detection work.

[0034] The working principle of this device is as follows: First, connect the external power supply. Push the device directly to the location where pipe weld inspection is needed using the roller 22. Then, pass the pipe through the first outer detection ring 4 and the second outer detection ring 16. Next, twist the positioning screw 24 on the positioning plate 23 to fix the device in its current position. After this preparation is complete, the operator can move away from the device. Then, the X-ray machine 2, digital detector 3, X-ray probe 11, ultrasonic flaw detector 14, and ultrasonic probe 18 are all electrically connected to the wireless drive controller 15. Thus, the external operator can remotely control the X-ray digital non-destructive testing device to inspect the pipe weld via the wireless drive controller 15. Flaw detection is performed to avoid the health risks of X-rays and ultrasound from personnel getting too close. Then, the X-ray machine 2 is turned on to provide X-rays to the X-ray probe 11. Next, the telescopic cylinder 9 is turned on, allowing it to move the X-ray probe 11 closer to the pipe weld. Then, the drive motor 12 is turned on, causing the drive gear 13 to rotate. This meshes with the first detection gear ring 7, causing the X-ray probe 11 to rotate at a constant speed. The X-ray probe 11 rotates in a circle around the pipe weld, and the emitted X-rays are received by the digital detector 3, transmitting the flaw detection data to... The remote operator then turns on the switch of the electric slide rail 20, causing the electric sliding sleeve 21 and the electric slide rail 20 to move the entire digital gantry inspection frame 1 forward, so that the second outer detection ring 16 is placed on the outside of the pipe weld for the second time. Then, the second outer detection ring 16 is placed on the outside of the pipe weld for the second time, and the second detection gear ring 17 is rotated circumferentially by the second detection gear ring 17, allowing the ultrasonic flaw detector 14 to assist the ultrasonic probe 18 in emitting ultrasonic waves, thus completing the secondary flaw detection. This ultrasonic flaw detection compensates for the limitations of X-ray flaw detection, forming a multi-modal non-destructive testing capability for this X-ray digital non-destructive testing device. This design can also avoid the occurrence of difficult-to-detect area-type defects in X-ray flaw detection, such as... In cases of incomplete penetration, the depth of the defect can be precisely located, compensating for the ambiguity of X-rays in defect characterization. After the current pipeline weld inspection is completed, the X-ray machine 2 and ultrasonic flaw detector 14 are turned off, and the device is pushed to the next pipeline location to conduct pipeline weld inspection. Finally, after completing the installation and use of the entire X-ray digital non-destructive testing device according to the above operations, the switches of X-ray machine 2, telescopic cylinder 9, drive motor 12, ultrasonic flaw detector 14, and electric slide rail 20 are turned off. If not used for a long time, the external power supply can be disconnected. This completes the use of the pipeline weld X-ray digital non-destructive testing device.

[0035] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
