In the prior art, when the probe moves in a pipe and stops when encountering a defect, the probe is marked and pulled out, and the distance from the probe to a mark, namely the distance from the defect to a pipe orifice is measured, so that the detection efficiency is low and the detection time is wasted.

Disclosure of Invention

In order to look for more effectual implementation scheme, the utility model provides a from range finding vortex probe marks measurement range finding mark on tubular product vortex inspection probe, makes things convenient for measurement personnel's use, reduces measurement personnel and operates repeatedly and measured step to practice thrift operating time, effectively solve the problem in the background art.

In order to achieve the purpose, the utility model discloses a from range finding eddy current probe, including probe body and probe line, the cover has an outer tube on the probe line, the outer tube surface is provided with the mark scale in succession, swing joint between probe body and the outer tube.

Furthermore, the pipe diameter of the outer sleeve is smaller than the diameter of the probe body.

Furthermore, a flexible lantern ring is installed at one end, close to the outer sleeve, of the probe body, and the diameter of the surface of the flexible lantern ring is smaller than that of the probe body.

Furthermore, a plurality of large scale marks are uniformly arranged on the surface of the marked scale, and a plurality of small scale marks are uniformly arranged between every two adjacent large scale marks.

Furthermore, the large scale marks are enclosed and encircled on the surface of the outer sleeve in an annular line mode, and the large scale marks are made of fluorescent materials.

Further, the outer sleeve inner wall passes through the protective layer and the contact of probe line, the protective layer includes that a plurality of evenly sets up the contact lantern ring at the outer sleeve inner wall, contact lantern ring outer wall sets up to the protruding form of arc, and is adjacent be provided with the transition arc board between the contact lantern ring.

Compared with the prior art, the utility model discloses a polymer sheet material thermal radiation flexibility becomes shape method and method has following beneficial effect:

the self-ranging eddy current probe in the scheme can meet different detection standards, and when some problems are found in detection, the distance position can be directly obtained by reading the marking numerical value on the probe; the method is simple to operate, and can effectively save detection time.

Additional aspects and advantages of the invention will be set forth in part in the description which follows and, in part, will be obvious from the description, or may be learned by practice of the invention.

Detailed Description

Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below by referring to the drawings are exemplary only for explaining the present invention, and should not be construed as limiting the present invention.

Please refer to fig. 1 to 3, the utility model discloses a from survey apart from eddy current probe, including probe body 1 and probe line 2, the cover has an outer tube 3 on the probe line 2, outer tube 3 surface is provided with mark scale 4 in succession, swing joint between probe body 1 and the outer tube 3, in this scheme, examine time measuring, through promoting outer tube 3, insert probe body 1 and detect the eddy current in the tubular product, when detecting defective position, through mark scale 4 on the direct observation outer tube 3, can accurately know the position that the defect exists to avoid the process of repeated measurement after discovering the defect, save time effectively improves detection efficiency.

The pipe diameter size of outer tube 3 is less than the diameter size of probe body 1, guarantees that outer tube 3 can not produce the interference or block the effect to probe body 1 after entering into tubular product.

The probe body 1 is close to the one end of outer tube 3 and installs flexible lantern ring 6, the diameter on flexible lantern ring 6 surface is less than the diameter of probe body 1, through the guard action of flexible lantern ring 6 for the contact position of probe body 1 and outer tube 3 can not take place the extrusion or collide, plays good guard action to probe body 1.

The surface of the marked scale 4 is uniformly provided with a plurality of large scale marks 7, a plurality of small scale marks 8 are uniformly arranged between the adjacent large scale marks 7, the large scale marks 7 are enclosed on the surface of the outer sleeve 3 in an annular line mode, the large scale marks 7 are made of fluorescent materials, and the marked scale 4 consisting of the large scale marks 7 and the small scale marks 8 can be directly read to obtain data after measurement, so that the position with defects in the pipe is judged.

Furthermore, because the large scale mark 7 is wound on the surface of the outer sleeve 3 in a closed surrounding mode, the scale of the large scale mark 7 can be read from any angle direction during actual detection, so that accurate data can be read conveniently.

The inner wall of the outer sleeve 3 is contacted with the probe line 2 through a protective layer 5, the protective layer 5 comprises a plurality of contact sleeve rings 9 which are uniformly arranged on the inner wall of the outer sleeve 3, the outer walls of the contact sleeve rings 9 are arranged to be arc-shaped convex, and are adjacent to each other, and transition arc plates 10 are arranged between the contact sleeve rings 9.

Because relative slip between outer tube 3 and the probe line 2, and when sliding, the probe line 2 surface can receive the wearing and tearing effect because of blockking, slide protection through the built-in protective layer 5 of outer tube 3 inner wall, when outer tube 3 slides on probe line 2, a plurality of contact lantern rings 9 and the contact of probe line 2 surface, after the contact, because contact lantern ring 9 surface is the protruding form of arc, reduce the friction effect when sliding, and the transition arc board 10 between the adjacent contact lantern ring 9, make the transition between the adjacent contact lantern ring 9 smooth, reduce the resistance effect that exists, guarantee can not appear excessive friction between outer tube 3 and the probe line 2, all played good guard action to outer tube 3 and probe line.

The foregoing is only a partial embodiment of the present invention, and it should be noted that, for those skilled in the art, a plurality of modifications and decorations can be made without departing from the principle of the present invention, and these modifications and decorations should also be regarded as the protection scope of the present invention.
