Description
Technical field
The invention belongs to technical field of nondestructive testing, and in particular to a kind of probe drive for Spherical Ring welding line ultrasonic inspection
Dynamic device.
Background technique
For many pressure resistant vessels due to the needs of manufacturing process, shell is then sectional making connects by welding
It is molding, so on its housing can there are circular welds.Since container uses under high temperature, high pressure conditions for a long time, need
State-detection is periodically carried out to it, and mainly the quality condition of weld seam is detected.The ultrasound examination of automation is to this
A kind of effective means that class weld seam is detected can record in real time the detection signal of ultrasonic probe, be convenient for later analysis with
Record.According to the regulation of ultrasonic inspection, when being examined to girth joint, ultrasonic probe other than checking weld seam region itself,
It also needs to detect the material within a certain range of weld seam two sides, to realize the complete detection to weldquality, these regions
It is referred to as tested region altogether.At this time, it is necessary to by a probe drive device, carry ultrasonic probe in tested region
Upper reciprocating motion, so that the signal of ultrasonic probe can be by all region overlays to be checked, the depth of weld seam is deeper, then is detected area
The width in domain just needs wider；During ultrasonic probe moves back and forth, probe needs tight with a relatively stable state
The closely connected surface together in tested region, and do not generate additional shaking as far as possible in moving process, to guarantee the matter of ultrasonic signal
Amount.
Girth joint on pressure resistant vessel is usually that two sections of cylindrical structures to form are formed, but at the top of some containers
Or bottom, there are the girth joints for being welded and being formed between cylindrical structure and hemispherical dome structure, from cutting on axis direction
Face sees that the side of such weld seam is straightway, and the other side is arc section.When carrying out ultrasonic examination to such girth joint, need
Move back and forth probe continuously on arc section in straightway.
Device common at present is to arrange in the axial direction, and driving ultrasonic probe moves in a straight line.This scheme is for two sections
The girth joint that cylindrical structures to form is formed, can effectively be detected；But to cylindrical structure and hemispherical dome structure pair
When connecing the boxing to be formed and being detected, when device is moved from straightway to arc section, the more remote then device of the distance of movement and container
Spacing between outer wall is bigger, and probe, which needs to stretch out farther distance just, at this time can fit to the arc surface of container outer wall
On, and pop one's head in and need from the outer wall that horizontality varies continuously to that very big inclination angle can just fit to spherical surface.By such side
Formula inspection, has the following problems: (1) telescopic extensions of ultrasonic probe are too big, bring to the stability of structure design and device
It influences, since part processes the fit-up gap of inevitable error and stretching structure objective reality, excessive cantilever elongation
Probe can be made to generate biggish shaking when moving back and forth；(2) the flip angle variation range of ultrasonic probe is too big, along straight
Line is bonded bad situation with will appear probe on arc section when reciprocating motion；Finally make the detection signal of automatic ultrasonic inspection
It is second-rate or even discontinuous.
It is therefore desirable to design a kind of structure more adduction for the spherical surface girth joint being spliced to form in cylindrical section and spherical surface
The probe drive device of reason, to improve the quality of automatic ultrasonic detection.
