End is placed in outside outer rotation inner ring.
In use, probe is put into outer rotating ring inner ring first, guide sleeve is supported probe, is suspended at probe
In outer rotating ring, then the utility model is placed on the outside of tube body to be detected, and make multiple petaloid cover boards and tube surfaces
Relatively, guide sleeve is then held, outer rotating ring is rotated, is popped one's head in motionless, inner sleeve is fixed, and then multiple petaloid cap locations
It is motionless, outer rotating ring endocyclic outer wall and shift(ing) ring inner wall bolt, and then shift(ing) ring is moved along outer rotating ring inner ring, shift(ing) ring
It is mobile to multiple petaloid cover boards, and the guide groove on shift(ing) ring is mobile respectively along corresponding gib block, and shift(ing) ring drives more
A push rod is mobile to petaloid cover board direction, and then multiple push rods gradually push the closure flap that multiple petaloid cover boards are formed open, root
According to probe diameter size, the aperture of multiple petaloid cover boards is adjusted, pushes guide sleeve along outer rotating ring inner ring, guide sleeve, which pushes, to be visited
Head contacts the release popped one's head between multiple petaloid cover boards and tube surfaces, is detected, when needing mobile probe, slightly
The outer rotating ring of micro- reverse rotation, multiple petaloid cover boards are closed slightly, and then are protected the contact surface of probe and pipe fitting, are avoided
In moving process and part generates friction, reaches when carrying out non-destructive testing to tube body, the purpose protected to probe.
Beneficial effect.
One, structure is simple, convenient and practical.
Two, cheap, it is easy to spread.
Three, the protection effect to probe can be effectively improved.
Detailed description of the invention
Fig. 1 is a kind of structural schematic diagram of phased array detection probe protective device of the utility model.
In attached drawing
