[0027] Example two

[0028] In order to make the detection probe maintain a relatively stable distance from the weld at all times, as shown in Figure 2 , Figure 3 and Figure 4 , in this embodiment, the shell 31 includes a sleeve 311, and the outer side of the bottom of the sleeve 311 is fixedly installed with a cornice 312, the cornice 312 adopts an L-shaped structure design in section, and the outer wall of the cornice 312 is provided with a limiting groove 3121. The L-shaped structure design of the cornice 312 provides a stable support platform, and the design of the limiting groove 3121 enables the positioning screw 42 to accurately position the carriage 41, enhancing the stability and accuracy of the moving assembly 4 in circular motion.

[0029] Further, the moving assembly 4 comprises a sliding frame 41 which is slidingly inserted on the eaves 312 opposite the shell 31, and the sliding frame 41 is provided with screw holes in the front surface and is screwed with a positioning screw rod 42. In the design, the sliding insertion of the sliding frame 41 allows the moving assembly 4 to move flexibly on the eaves 312, and the position of the detection probe 6 can be adjusted conveniently during the detection operation to detect the weld. Through the screw hole and the threaded installation of the positioning screw rod 42, the position of the sliding frame 41 can be positioned accurately, the stability of the movement of the sliding frame 41 is ensured, and the detection accuracy is improved.

[0030] Further, one end of the positioning screw rod 42 penetrates through the outer wall of the sliding frame 41 and is in contact with the outer wall of the eaves 312 but is not fixedly connected, and the other end of the positioning screw rod 42 is fixedly installed with a rotating rod. In the design, one end of the positioning screw rod 42 is in contact with the eaves 312 but is not fixedly connected, and the other end is fixedly installed with a rotating rod, which not only ensures the flexibility of the moving assembly 4, but also ensures the stability during the detection process.

[0031] Further, the annular air bag 32 is provided with a charging nozzle 321 which is installed in the hole and is in communication, one end of the charging nozzle 321 penetrates through the sleeve 311 away from the annular air bag 32, the charging nozzle 321 is provided with a valve core inside, and the inner wall of the annular air bag 32 is provided with transversely distributed anti-skid lines. In the design, the setting of the charging nozzle 321 enables the annular air bag 32 to be inflated and deflated quickly, which improves the installation and disassembly efficiency of the equipment. The anti-skid line design of the inner wall of the annular air bag 32 increases the friction between the air bag and the second circular pipe 2, which prevents the equipment from sliding or shifting during use.

[0032] Further, the self-adaptive assembly 51 comprises a telescopic rod and a compression spring sleeved outside the telescopic rod, the top of the telescopic rod is fixedly connected with the bottom of the sliding frame 41, and the bottom of the telescopic rod is fixedly connected with the top of the caster 52.

The design of the self-adaptive assembly 51 reduces the friction between the caster 52 and the outer wall of the first circular pipe 1, protects the pipe surface, and prolongs the service life of the pipe.

[0033] Before using this invention, ensure all components are intact and undamaged, especially the phased array radar used in the detection probe 6, which must be functioning correctly. The positioning assembly 3 is movably mounted on the outer wall of the vertically welded second circular tube 2. The airbag 32 is inflated through the inflation nozzle 321 until its inner wall is in close contact with the outer wall of the second circular tube 2, ensuring stability and preventing slippage. A movable assembly 4 is movably mounted on one side of the positioning assembly 3, with an adjustment assembly 5 fixedly mounted at its bottom. The detection probe 6 is fixedly mounted on the side of the adjustment assembly 5 closest to the second circular tube 2. A positioning screw 42 is used to limit the movement of the carriage 41 on the eaves 312, ensuring the carriage 41 does not wobble on the eaves 312, thus guaranteeing the stability and accuracy of the detection probe 6. The adaptive assembly 51 automatically adjusts the distance between the casters 52 and the outer wall of the first circular tube 1, ensuring the casters 52 always remain in contact with the outer wall of the first circular tube 1, even if the outer wall is uneven. The moving component 4 moves in a circular motion along the positioning component 3, during which the caster 52 remains in contact with the outer wall of the first circular pipe 1 under the action of the adaptive component 51. This design ensures the stability and flexibility of the equipment when moving along the weld, while reducing friction and damage to the pipe surface. The phased array radar detection probe 6 is activated to begin precise inspection of the weld and its edges. The phased array radar can provide detailed information about the weld quality, including weld integrity and potential defects. During the inspection, data fed back from the probe is collected and analyzed in real time to assess the quality and integrity of the weld. After the inspection is completed, the operation of the phased array radar probe is stopped, and the equipment is removed from the pipe as needed for further data analysis and report preparation.

[0034] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description.
