[0038] Working principle: in use, the support seat 1 as the foundation support component, the translation slide rail 2 and the translation motor 3 on it work together. The translation motor 3 drives the moving frame 4 connected with it to slide along the translation slide rail 2, realizing the horizontal position adjustment to adapt to the measurement position requirement of different pipes. The vertical slide rail 6 and the moving belt 7 on the outer surface of the moving frame 4 provide the vertical movement guide and power transmission path for the transverse frame 8. The power piece 9 drives the moving block 10 to move on the transverse frame 8, and then drives the adjusting mechanism 11, the mounting frame assembly 12 and the probe piece 13 to move flexibly in the three-dimensional space, accurately positioning to the pipe to be detected part. The moving plate 1101 in the adjusting mechanism 11 bears the installation rail 1102 and the limiting frame 1103.

When installing or adjusting the mounting frame assembly 12, pull the pull rod 1108 to stretch the spring 1106, and the limiting strip 1107 is retracted into the limiting groove one 1105, leaving space for the mounting frame assembly 12. After positioning, release the pull rod 1108, the spring 1106 rebounds to push the limiting strip 1107 to pop out, clamping the mounting frame assembly 12 by the chamfer design, preventing it from being displaced by vibration.

The limiting plate 1206 blocks the probe piece 13 at the edge to prevent it from falling out, ensuring the stability and reliability of the probe piece 13 during the whole measurement process. The probe shell 1301 realizes accurate positioning by the same diameter as the positioning hole 1204 on the installation plate 1201, ensuring the coincidence of the central axis and improving the measurement accuracy. The positioning bolt 1304 of the installation frame one 1302 and the installation frame two 1303 is double reinforced, stabilizing the probe piece 13 and reducing signal interference caused by shaking during measurement. During measurement, the probe 1305 outside the probe shell 1301 directly contacts the pipe wall, emits ultrasonic waves and receives reflected waves. By analyzing the reflection wave information, the pipe wall thickness data is calculated. The installation frame two 1303 is close to the adjusting mechanism 11, which assists in supporting and positioning the probe shell 1301, ensuring that the probe 1305 is perpendicular to the pipe wall, and ensuring that the measurement data is true and reliable.
