Background technology
UT (Ultrasonic Testing) is to utilize ultrasonic energy to penetrate the depths of metal material, and when entering another cross section by a cross section, and the characteristics that reflection occur in interface edge check a kind of method of part defect.Most steel pipes such as oil well pipe, high-pressure boiler tube etc. all need to detect through ultrasonic test equipment.
At present, steel tube supersonic flaw detecting equipment adopts the mode that probe rotation, steel pipe straight line are carried.Steel pipe is that the pinch roll by a plurality of three-roller centring devices is clamped steel pipe and sent and send steel pipe to the UT (Ultrasonic Testing) rotary body and detect a flaw, therefore, the deviation of the machine center of the pinch roll of three-roller centring device directly has influence on steel pipe center and ultrasonic test equipment rotary body center degree of agreement, three-roller centring device is by gantry base, three rollers centering wheel, drive motor and hydraulic cylinder form, Main Function is to guarantee that steel pipe is under the clamping of three rollers centering wheel, the steel pipe center is consistent with flaw detection main frame (probe) center, if three rollers centering wheel has in various degree wearing and tearing, can cause the deviation of steel pipe center and flaw detection host center, make plant machinery concentricity precise decreasing, undetected in the flaw detection process, rate of false alarm increases.
Because the mechanical concentricity departure degree of ultrasonic test equipment is directly connected to the reliability of result of detection, therefore, the concentricity situation that in time detects, follows the tracks of the flaw detection unit is carried out centering to steel tube supersonic flaw detecting equipment and is just seemed particularly important.
The utility model content
For addressing the above problem, the utility model provides a kind of steel tube supersonic flaw detecting equipment centralising device, can judge fast the offset direction of equipment concentricity, realizes the centering of steel tube supersonic flaw detecting equipment.
For achieving the above object, steel tube supersonic flaw detecting equipment centralising device of the present utility model, described ultrasonic test equipment comprises three-roller centring device and the UT (Ultrasonic Testing) rotary body that pinches steel pipe, this centralising device comprises steel wire, the first positioning tube, the second positioning tube, the first height regulating mechanism, the second height regulating mechanism and a plurality of centering ring, described centering ring is fixed in described three-roller centring device and the UT (Ultrasonic Testing) rotary body, described steel wire passes described the first positioning tube successively, the first height regulating mechanism, a plurality of centering rings, the second height regulating mechanism and the second positioning tube, its two ends are fixedly connected with respectively a gravity suspension member.
The center pit of described the first positioning tube and the second positioning tube and steel wire coupling.
Steel tube supersonic flaw detecting equipment centralising device of the present utility model, when adjusting the machine center of three-roller centring device, can observe directly the deviation of three-roller centring device machine center in the position of centering ring center pit by steel wire, thereby instruct operating personnel to carry out centering.By steel tube supersonic flaw detecting equipment centralising device of the present utility model, can effectively control the mechanical concentricity precision of steel tube supersonic flaw detecting equipment, can avoid causing because of defect-detecting equipment machinery concentricity the difference of circumferential sensitivity in the flaw detection process, cause undetected, the wrong report of flaw detection, the quality that is conducive to detect a flaw improves.
