When the external-wearing type eddy current inspection probe automatic moving device is used for inspection, rapid and uniform movement can be realized, and inevitable shaking caused when a person holds the probe during conventional inspection can be eliminated, so that the inspection signal is more accurate, the problems of missing inspection, misjudgment and the like of defects are effectively overcome, and the automation of pipe fitting defect inspection is preliminarily realized.
Description
Technical Field
The utility model relates to an electromagnetic testing technique application, specific content is outer formula eddy current testing probe automatic moving device of wearing.
Background
The eddy current detection technology has a good application prospect in the production of the modern petrochemical industry, and because the pressure pipeline is widely applied to the petrochemical industry, cracks and corrosion in the pipeline are common defects in the petrochemical production process, great potential safety hazards can be generated in the further development of the pressure pipeline, and unpredictable loss is brought. At present, the advanced detection method for the pipeline defects mainly comprises rays, magnetic leakage, ultrasonic waves, acoustic emission, eddy currents and the like. Compared with other detection methods, the eddy current method does not need pretreatment and intermediate media for workpieces, can realize non-contact detection, is convenient, quick and environment-friendly to detect, but the hand shake inevitably affects the detection effect of the probe and causes errors when the probe is manually moved for detection.
Disclosure of Invention
In view of the above disadvantages, the device aims to automatically detect the defect rapidly and uniformly during detection, and also can eliminate the inevitable jitter when a conventional detector holds the probe by hand, so that the measurement signal is more accurate, and the problems of missed detection, erroneous judgment and the like of the defect are effectively overcome.
In order to achieve the purpose, the technical scheme provided by the device is as follows:
outer formula eddy current inspection probe automatic shifting device that wears adopts five direct current gear motor (4) to drive by the pipeline removal of being surveyed as the power supply, and the probe is fixed to be laid on outer formula eddy current inspection probe automatic shifting device, can begin to carry out the work that detects the defect when the pipeline passes the probe, and the pipeline is whole to pass the back, and detection achievement. The tail end of the frame (1) is provided with a group of supporting wheels (2), and when the gravity center of the pipeline is pressed on the group of wheels, the pipeline can be stopped at the tail end of the moving device, so that the pipeline is prevented from falling and being injured. The device adopts the direct current speed reducing motor (4) with low rotating speed and large torque as a power source, and solves the problem that the detected pipeline cannot move due to insufficient power of the motor. The motor shaft is provided with a U-shaped wheel, and the wheel is sleeved with a rubber sleeve to increase the friction force on the wheel and reduce the possibility of skidding. Meanwhile, the device adopts left-side feeding, the right end discharges after detection is finished, and the next pipeline can be immediately put into the device after the flaw detection of one pipeline is finished, so that the non-continuity of the flaw detection operation of the pipeline is realized. This device adopts the three-section removable, because the overall length exceeds 1.9m, if make a whole can make this set of device of transport or transportation become very troublesome, so with this device split into left, middle, right triplex, nevertheless in the split for the straightness accuracy of guaranteeing all gear motor and gyro wheels, survey the square intraduct welding one section length and be 15 cm's little square pipe with the right side with the side of unit in a left side, the pipe can insert in the interface of middle frame, has guaranteed that the degree of accuracy of device is not cut down.
The present invention will be further explained with reference to the drawings and the embodiments.

Detailed Description
The technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.
The detected pipeline is placed on a left direct current speed reducing motor (4), the direct current speed reducing motor (4) is powered by a transformer, a switch is turned on, the pipeline moves forwards under stress, penetrates through an external penetration type eddy current detection probe fixed by a probe fixing part (3) and continues to move forwards after penetrating through the external penetration type eddy current detection probe, and the pipeline stays on a supporting wheel (2) until the friction force applied to the pipeline by the last direct current speed reducing motor (4) is not enough to enable the pipeline to continue to move forwards.
In addition, the embodiment is described in the specification, but the implementation process does not only include an independent technical solution, and for the sake of clarity, a skilled person may partially modify the above embodiment according to a specific working condition to achieve a better detection effect.
