Abstract

The utility model relates to a vortex fault inspector for oil transmission pipeline. The utility model consists of a front probe supporting part, a back tested pipe supporting part, an internal probe and an external probe. A drive wheel clamping unit and an oil pipe centering clamping unit are arranged below the front part. An oil pipe transmission roller and an automatic oil pipe centering unit are installed below the back part. The middle of the device has an internal probe and an external probe. The internal probe can enter the pipe by the supporting rod, while the external probe makes the fault inspection for the outside of the pipeline. The utility model has the advantages of simple structure, convenient installation and use, synchronized use of the internal probe and the external probe, capability in fault inspection measurement for any place inside and outside the oil pipe, as well as high precision and accuracy in fault inspection with full automatic nature.

Description

Full-automatic eddy current testing equipment

The utility model relates to a kind of oil pipeline failure detector.

At present, ultra-sonic defect detector is mostly adopted in detection to the metal tubes damage, utilize the ultrasound wave principle that the metal pipe material damaged portion is detected, also there is the metal of employing leakage field method to detect, this kind measurement mechanism is only comparatively convenient to the local flaw detection of pipeline, difficult especially for detection of pipeline large tracts of land or the flaw detection of pipeline depths, some place can't be detected, and makes troubles for a large amount of pipeline complete detection.

For solving the deficiency of above device, the purpose of this utility model provides a kind of full-automatic eddy current testing equipment, utilizes inside and outside two probes to detecting simultaneously inside and outside the pipeline, to reach purpose quick, accurate, that detect automatically.

Structural design of the present utility model is achieved in that this defectoscope is by base, anterior probe supporting part, rear portion measured tube supporting part and middle inside and outside probe are formed (as shown in Figure 1), its middle front part probe supporting part is made up of aligning tailstock and interior probe cramp bar, the cramp bar of in tailstock, popping one's head in the horizontal positioned, oil pipe driving wheel binding clasp is housed in the middle of the cramp bar, binding clasp is that two corresponding wheels are formed up and down, oil pipe respectively is housed on the binding clasp two-side supporting bar carries follower, the cramp bar bottom is equipped with two cramp bar cylinders simultaneously, oil pipe centering binding clasp is equipped with in bottom, support column inner end, and gauge tap is equipped with in the side; Rear portion measured tube supporting part is rolled by oil pipe feeder and active transportation to be formed, the centre is equipped with three oil pipes conveyings and is rolled, roll for active transportation the centre, both sides are that passive conveying is rolled, be placed with measured tube above, feeder is housed below the measured tube, and feeder connects with following electronic cylinder, and the measured tube follower head is equipped with turnover panel device impact switch and turnover panel device switch; The centre is inside and outside probe segment, interior probe is long cylindrical (as shown in Figure 2), its structure is that two ends are nut, the center is a coil rack, both sides are left angle sheave fixed cover and right angle sheave fixed cover, angle sheave is equipped with for 60 ° in the lateral separation, both sides are equipped with left and right sides fixed cover respectively, probe outside outside corresponding being equipped with of interior probe, outer probe is wound with two windings to be formed, and guides to controller by signal wire, in be equipped with in the front of probe, external diameter color spray mark and optoelectronic switch, oil pipe self-centering device is equipped with in the optoelectronic switch back, the pipe collar switch is equipped with in the side, and measured tube rolls on and can move forward and backward in conveying, and interior probe can directly reach the inside any old place of measured tube, positioning platform in center is housed below the outer probe, and power distribution cabinet is equipped with in the base the inside.

The utility model advantage: simple in structure, easy to install, inside and outside probe uses simultaneously, to the measurement of detecting a flaw of any old place inside and outside the oil pipe, and flaw detection precision height, accurate, full-automatic.

The utility model detailed structure is provided by following examples and accompanying drawing.

Fig. 1 is full-automatic eddy current testing equipment structure principle chart.

Fig. 2 is sonde configuration figure in the full-automatic eddy current testing equipment.

Its structure as shown in drawings, the front probe supporting part 1 power switch that exceeds has limited the working range of cramp bar, 2 is the aligning tailstock, 3 is interior probe cramp bar, has controlled the horizontal level of probe thus, and 4 are oil pipe conveying follower, front and back have two, middle 5 is oil pipe driving wheel binding clasp, and bearing support front end 6 is oil pipe centering binding clasp, control probe front position, the next door 20 is a gauge tap, and 21,22 is the cramp bar cylinder below the cramp bar; Rear portion measured tube supporting part, 13 roll for the oil pipe active transportation, and both sides are equipped with passive conveying and are rolled, and 12 is the oil pipe feeder, is driven by following electronic cylinder 16, and the measured tube front end is equipped with 11 oil pipe self-centering devices, and 18 is the pipe collar switch, and 17 is power distribution cabinet; Center probe part 8 is interior probe, and 7 is outer probe, and interior sonde configuration is that two ends 25,32 are nut, center 28 is a coil rack, and 27,30 is the angle sheave fixed cover, 26 31 be left and right sides fixed cover, 29 is angle sheave, and 26,31 is the two ends fixed cover, and 19 are center positioning platform, probe side 9 is the color spray mark, 10 is optoelectronic switch, and 23 are control binding clasp switch, and 14 is turnover panel device impact switch in the measured tube back, 15 is turnover panel device switch, and measured tube can be parked on any one position.
