Abstract
The utility model belongs to the technical field of non-destructive testing of tubular equipment with small inner diameters in a nuclear power station, and particularly relates to a universal joint tray of an ultrasonic probe for nondestructive flaw detection. A universal structure consisting of a probe carrier and a probe tray enables the probe to rotate in any direction in the probe tray along with the probe carrier so as to adapt to the variation of a detected surface; structures for limiting the probe carrier and the probe tray enable the probe carrier to move up and down in the probe tray along a guide groove on the probe tray or to rotate by adopting a rotary set screw as an axis; and the pressing force of a spring provides motive power for the universal function of the probe carrier so as to automatically adapt to the variation of the detected surface and to tightly attach to the detected surface. The universal joint tray of the ultrasonic probe for nondestructive flaw detection overcomes the defect that the prior art is inapplicable to connecting pieces with small pipe diameters as well as other tubular equipment, and improves the accuracy and the reliability of detection.

Background technology
In a circuit system of nuclear power station, the adapter of many minor diameters is arranged, because of this zone is in high-temperature high-pressure state for a long time, and be with highly radioactive heat eliminating medium therefrom to flow through, if leak in this zone, with serious security incident takes place, so must regularly check to the adapter weld seam and the safe end weld seam of these adapters.Adopting automation equipment that these weld seams are implemented ultrasonic inspection is a kind of important means commonly used.In the process of implementing the ultrasound wave self-verifying, probe compresses the signal stabilization situation that situation directly influences ultrasonic inspection with the applying on tested surface, therefore must have a kind of the device can make probe be adjacent to detected surface with certain pressure all the time in the scanning testing process.
Finish the ultrasonic examination of taking over weld seam, probe has radially and circumferential moving of both direction along tube wall in the scanning process.For making the scanning instrument can obtain stable signal in the scanning process, ultrasonic probe must radially with in circumferential two motion processes all be close to tube wall.But because that these take over calibers is less with respect to the Ultrasonic NDT caliber, can't adopt general general probe pallet pattern, therefore must design a kind of device and satisfy Ultrasonic Detection requirement under this kind situation.
Summary of the invention
The utility model purpose is to provide a kind of nondestructive examination ultrasonic probe universal joint pallet, can't be applied to the adapter of little caliber and the shortcoming of other similar tubular equipments to overcome prior art, improves the accuracy and the reliability that detect.
A kind of nondestructive examination ultrasonic probe universal joint pallet described in the utility model, comprise: probe carrier and probe pallet, the upper end of cylindrical shape probe pallet is equipped with probe carrier, the main body of probe carrier is a spheroid, have square hole in the middle of it, institute's opening square hole is complementary with the probe shape, and probe carrier cooperates the formation universal structure with the probe pallet; Symmetric arrangement has the rotation holding screw that runs through probe carrier on the probe carrier, the inner of each rotation holding screw is fixing with probe, the outer end is stretched in the gathering sill that probe pallet inwall offers, in rotation holding screw top 1 stop screw is arranged respectively, stop screw is fixed in the gathering sill of probe pallet, constitutes the position limiting structure of probe carrier and probe pallet; The probe tray bottom surface is furnished with volute spring, and the volute spring bottom is fixed on the bottom of probe pallet, apical support probe carrier bottom, the adaptive structure of formation probe carrier.
Described nondestructive examination ultrasonic probe universal joint pallet, helical spring quantity is 4.
Described nondestructive examination ultrasonic probe universal joint pallet, the volute spring symmetric arrangement.
The obtained effect of the utility model is:
(1) the utility model nondestructive examination ultrasonic probe universal joint pallet can be applied to the occasion of little caliber;
(2) universal structure formed of probe carrier and probe pallet: probe carrier cooperates the universal structure of formation with the face of cylinder of probe pallet, make probe can do the rotation of all directions with probe carrier in the pallet of popping one's head in, and adapts to the variation on tested surface with this;
(3) position limiting structure of probe carrier and probe pallet: be subjected to the popping one's head in restriction of pallet gathering sill and gathering sill top stop screw of the rotation holding screw on the probe carrier, limited rotating in a circumferential direction of probe carrier.Probe carrier can move up and down in the probe pallet along probe pallet gathering sill, can serve as the axle rotation with the rotation holding screw also;
(4) adaptive structure of probe carrier: during use, the rotary stopper screw does not push up stop screw, and promptly probe carrier all has certain activity surplus along gathering sill at above-below direction.The snap-in force of spring provides power for the universal function of probe carrier, with this variation that adapts to tested surface automatically, is close to tested surface.
