The operation principle of the pipe outer ring weld scanner is as follows：Pipe outer ring weld scanner when scanning weld seam due to
Weld seam is not a fixed value with the distance of chain type walking mechanism, so can make to produce site error between probe and weld seam,
Therefore it is necessary to have a probe adjusting mechanism is realizing the adjustment on pipeline axial direction of popping one's head in.In addition it is also necessary to adjust
Probe is in the position of pipeline radial direction.It is specific as follows：
1st, processing of rust removing is carried out to the boxing seam surface of pipeline before detecting, and weld grinding is smooth；Secondly by one
Long chain link 2-2 successively, short chain 2-4,2-5 roller are connected by link bolt 2-3, and are enclosed within pipeline outer wall, are finally separated
Chain link connected by connector block 2-7 and adjustment bolt 2-6；Changing the size of adjustment bolt tightening force makes chain type walking mechanism
Roller is just attached to pipeline outer wall and can normally roll.
2nd, probe is axially adjustable：
It is soft by detecting on computer when a pair of probes of scanner are when anisopleual with regard to weld seam during scanning
The feedback (can certainly artificial judgment) of part, drives adjustment motor to rotate to drive the rotation of leading screw, and the nut on leading screw is just
Can axially be moved along a straight line along pipeline, the probe assembly adjustment position being connected on nut makes weld seam be located at this in probe
At the heart.Here it is completing process of the probe assembly to the axial tracking of weld seam by screw-nut body.It is finally etc. to be operated
Whether personnel's instruction starts to detect weld seam.
3rd, the radial direction adjustment of probe：
The radial direction adjustment of probe is realized by spring bracing.Pinch roller is pressed in all the time weld seam by compression deformation of the spring
On, probe assembly can so maintained a certain distance with pipeline outer wall, scanning of the probe in weld seam radially is realized, and it is full
The scanning of sufficient supersonic sounding is required, in addition during scanning, spring should place and compressive state always.
4th, adjust motor 3-7 and adjustment motor 3-7 completes predetermined task according to instruction：Adjustment motor 3-7 drives whole
Chain type walking mechanism 2 does stable circumferential movement around pipeline outer wall, completes the circumferential scanning along weld seam.Adjustment motor 3-7 drives
Leading screw, the nut being connected with leading screw, so as to probe axially-movable of also complete, can make under the rotation of leading screw along pipeline axially-movable
Ensure certain position relationship between probe and weld seam.The motion in both direction is completed by two motors, it is ensured that right
The high accuracy of weld seam scanning, comprehensive requirement.
5th, after the completion of scanning, weld seam scanning image is shown on computers, image information is recognized by image recognition software
And judge the weld seam of pipeline whether safety approval.If testing result is qualified, then after the completion of waiting other operations on pipeline,
Pipeline can be sunk to the medium pending conveying task of sea water.
