Specifically, the pressure pipeline 9 is placed in the first circular ring 1, the swing rod 3 is forced to flip outward, the elastic member 32 is forced to store the reset power, the probe 4 is coupled to the outer surface of the pressure pipeline 9, and the pressure pipeline 9 is non-destructively tested by ultrasonic waves. The mounting seat 2 and the swing rod 3 make a circular motion in the first circular ring 1, and the outer circumference of the pressure pipeline 9 can be fully tested. At the same time, due to the setting of the elastic member 32, the probe 4 always maintains a certain pressing force and is coupled to the outer surface of the pressure pipeline 9, ensuring the coupling effect and stability of the probe 4. The device can be used to detect pressure pipelines 9 of different diameters, thereby improving the scope of application and flexibility of the device.

[0022] Furthermore, in the specific implementation, Figure 1 , 4As shown, a pressure pipeline detection device disclosed also includes a second ring 5, and a plurality of telescopic rods 6 are evenly arranged between the second ring 5 and the first ring 1. One end of the telescopic rod 6 is connected to the first ring 1 by a ball joint, and the other end is connected to the second ring 5 by a ball joint. It should be noted that the telescopic rod 6 is usually composed of a cylinder and a piston rod. There is a certain damping force in the extension and contraction of the telescopic rod 6 and the rotation of the ball joints at both ends. In the natural initial state, the piston rod of the telescopic rod 6 has a certain stroke pre-compression, one end of the piston rod of the telescopic rod 6 is located in the middle position of the cylinder, and the telescopic rod 6 is in a horizontal state. The second ring 5 is relatively fixed, and the pressure pipeline 9 is placed in the first ring 1 and the second ring 5, which can be used to detect curved pipes with a certain curvature, thereby improving the scope of application and flexibility of the device. In addition, the swing rod 3 can also be a telescopic structure, which further improves the flexibility of detecting and diagnosing the shape change of the pressure pipeline 9; in addition, the second ring 5 is connected to a bracket 7, and a slide rail 8 is provided below the bracket 7. The bracket 7 includes a pulley 71 slidably connected to the slide rail 8. Specifically, in the embodiment, the sliding surface of the pulley 71 is provided with an annular groove , the slide rail 8 is engaged and clamped in the groove, so that the first ring 1 and the second ring 5 slide synchronously along the slide rail 8, so as to realize comprehensive detection of the length direction of the pressure pipe 9, and improve the comprehensiveness and efficiency of the detection.

The bracket 7 can be fixed to the second ring 5 by welding; preferably, the first ring 1 and the second ring 5 are both composed of two semi-circular arc frames that are docked together. Specifically, in this embodiment, the first ring 1 and the second ring 5 are both composed of upper and lower semi-circular arc frames, which are riveted by the concave and convex structures at the ends, and are fixed in series by bolts on the sides. The structural design is simple and stable, easy to manufacture and install, and suitable for the detection of the installed and running pressure pipe 9. It should be noted that the arrangement of the telescopic rod 6 should avoid the docking seam position of the two semi-circular arc frames to avoid interference. The two semi-circular arc frames can also be a left-right docking structure. Correspondingly, the bracket 7 also needs to be split into left and right structures and connected by bolts.

[0023] Furthermore, in the specific implementation, Figure 1-3 As shown, the inner wall circumference of the first ring 1 provided in the embodiment of the utility model is provided with a convex tooth 11, a driving motor 21 is fixed on the mounting seat 2, and a gear 22 meshingly connected with the convex tooth 11 is provided on the output shaft of the driving motor 21. The driving motor 21 drives the gear 22 to rotate, and through the transmission cooperation between the gear 22 and the convex tooth 11, the mounting seat 2 is driven to move in a circular motion within the first ring 1, thereby improving the detection efficiency.

[0024] Furthermore, in the specific implementation, Figure 2As shown, a retaining ring 12 is coaxially arranged on the inner wall of the first circular ring 1 provided in the embodiment of the utility model, and a mounting seat 2 is provided with a retaining groove 20 on the contact surface with the inner wall of the first circular ring 1 for engaging with the slider of the retaining ring 12, thereby ensuring a firm connection between the mounting seat 2 and the inner wall of the first circular ring 1, avoiding loosening or falling off of the mounting seat 2 during the detection process, and improving the reliability and stability of the device.

[0025] Furthermore, in a specific implementation, the elastic member 32 provided in the embodiment of the utility model is a torsion spring or a spiral spring.
