During support, it is ensured that the object everywhere can detected by magnetic sensitive probe, so as to, cylinder to be checked only needs
In the inside of cylinder-shaped bracket through can once complete to detect, detection cycle is substantially reduced, improves detection efficiency, reduced
The workload of detection；
2）Without the relative position of magnetic sensitive probe and cylinder on cylinder circumferencial direction is adjusted, so as to eliminate Lou
The possibility of inspection；
3）Magnetic sensitive probe is fixed on to the push rod end of electric pushrod so that the position of magnetic sensitive probe can be along push rod
Length direction motion, be in appropriate test position so as to the different adjustment magnetic sensitive probes according to drum diameter to be checked,
The Non-Destructive Testing to different-diameter cylinder is realized, the cylinder of given diameter can only be detected if no electric pushrod, is reduced
