Pipe is to be managed continuously by the non junction that butt welding or inclined weld technology are welded at the flexible pipe more than hundred meters by plurality of sections length continuously, and length generally reaches hundreds of rice to several kms.Be a kind of by the steel band moulding, the weld pipe that after resistance vertical masonry joint welding (ERW), obtains, with respect to using the conventional oil pipe that is threaded and goes into the well, whole of coiled tubing is coiled on the swift, and nothing is threaded, through directly going into the well after the injector head alignment.
Owing to taking place to cause very big cost when oil pipe is tired, so in order to strengthen managing continuously the reliability of operation, the detection of carrying out defective before pipe carries out site work continuously is of great value.Diameter, wall thickness, transverse defect, longitudinal defect, ovality to continuous pipe body detects at present, the general single detection modes such as ultrasound wave, Magnetic Flux Leakage Inspecting, EDDY CURRENT that adopt, the problem that exists is: can not reach comprehensive detection to continuous pipe, Ultrasonic Detection has higher sensitivity to the defective of continuous pipe inside, and eddy current and Magnetic Flux Leakage Inspecting have higher sensitivity to continuous tube-surface, nearly surperficial defective.All single checkout equipments all can't be simultaneously comprehensively detect the defective and the physical dimension of continuous pipe.
Summary of the invention
The utility model provides a kind of continuous pipe the cannot-harm-detection device, can't carry out comprehensively the accurately shortcoming of detection to continuous pipe to overcome in the prior art.
For achieving the above object, the technical solution adopted in the utility model is: a kind of continuous pipe the cannot-harm-detection device, comprise gear train, centration axis, supersonic detection device, eddy current testing device, position detecting device and industrial computer, described supersonic detection device comprises four ultrasonic probes that are oppositely arranged in shell and the shell, its special character is, described ultrasonic probe is arranged on the adjusting mechanism respectively, described adjusting mechanism comprises mount pad, the probe holder, adjusting screw(rod), spherical, worm screw, worm gear and rotating shaft, described shell is provided with four probe mounting holes that are communicated with internal cavity, mount pad is fixed in the probe mounting hole outside, be arranged with mobilizable spherical in the mount pad, two opposite flanks of spherical are provided with concentric rotating shaft, rotating shaft is arranged in the mount pad movably, one end of rotating shaft is provided with the worm-drive assembly, and the worm-drive assembly comprises turbine and the worm screw that is engaged with; Described probe holder is arranged at movably in the spherical and is vertical with rotating shaft, and ultrasonic probe is arranged in the probe holder, adjusting screw(rod) along probe holder arranged outside and with the screw-threaded engagement of probe holder outside; The end of ultrasonic probe is positioned at the probe mounting hole.
With respect to prior art, the utlity model has following advantage:
1, the defective resolution characteristic is strong: utilize ultrasound wave and vortex combined continuous pipe is detected a flaw, can carry out comprehensive detection to diameter, wall thickness, inherent vice, surface, near surface flaw, the ovality of continuous pipe, simultaneously ultrasonic and EDDY CURRENT are combined, the defective resolution characteristic is strengthened greatly.
2, the detection error is little: in supersonic detection device, increased adjusting mechanism, can realize the position of probe is carried out flexibly, regulated accurately, make the detection sensitivity of ultrasonic probe increase, can reduce the detection error that heart is not caused owing to probe greatly.
3, little, in light weight, the compact conformation of volume can detect on-the-spot the use easily.
