[0026] During use, the large workpiece is moved to the product bracket 1 in the middle of the rotary track 9 through a carrier flatbed truck. The telescopic beam 5 is rotated 90° through the rotating structure 4, and the telescopic beam 5 is adjusted so that it crosses the outer wall of the workpiece to reach the position to be detected, and the vertical telescopic arm 6 is adjusted to the detection part.

The ray source is turned on for detection. The ray source and the flat panel detector 7 are synchronously moved according to the detected part of the workpiece for automatic detection until the detection of the entire workpiece is completed and the exposure is stopped.

[0028] It should be noted that in order to ensure that after the position of the flat panel detector 7 changes due to the adjustment of the height of the telescopic arm 6, the ray machine tube head bracket 10 is arranged opposite to its position. The ray machine tube head bracket 10 of the present utility model is connected to it through a slide rail installed on the ray machine mounting frame 3.
