AI Technical Summary

Technical Problem

Existing X-ray inspection devices are not suitable for inspecting pipes with varying radii, irregular shapes, or small diameters. They have low automation levels, require manual adjustments which lead to large errors and increase radiation risks.

Method used

Design an auxiliary device for X-ray inspection of variable radius pipes. It adopts a variable radius inspection mechanism and a walking mechanism, and combines strain gauges and lead screw mechanism to achieve automatic adjustment. It adapts to different pipe diameters through a rotary motor and power mechanism, reducing manual operation.

Benefits of technology

It enables adaptive detection of different pipe diameters, improves automation, reduces human error and radiation risk, and enhances detection efficiency and image quality.
