Description
Technical field
The utility model belongs to building engineering field, relates generally to the Non-Destructive Testing of girder steel, is specifically related to a kind of girder steel pick-up unit.
Background technology
In the roof structure of steel-structure factory building and various steel building, girder steel bears the load of various complexity, be easy to form region of stress concentration therein, cause implicit damage, such as overhead crane applies fatigue load to crane girder in traveling process, easily form minute crack in beam inside, when through without these slowly growing cracks when early warning, so that last girder steel ruptures rapidly.And for example some girder steels are welded by steel plate or shaped steel, and after welding, inside configuration exists unrelieved stress, and commissure more or less exists some defects simultaneously, such as crackle, slag inclusion, pore, under outside load action, these factor actings in conjunction, are easy to form region of stress concentration.And the position that is connected is carried out at girder steel and other components, to give a farfetched interpretation on girder steel bolt hole or form some sharp-pointed grooves and cause stressed very complicated being easy to cause stress to concentrate and form implicit damage for the needs connected.For reducing the destruction to building structure as far as possible, should lossless detection method be used as much as possible to detect building, conventional lossless detection method can only detect some and develop shaping gross imperfection, and be subject under various complicated loads for girder steel, the implicit damage of its inside is difficult to be found, metal magnetic memory detection technology can not only detect the gross imperfection of girder steel, more can detect that the early stage stress of component is concentrated and implicit damage.
The principle of magnetic memory detection technology is: ferromagnetic component can be very high at the stress of region of stress concentration, for making the total free energy minimization in component, be subjected to displacement so that the arrangement of magnetic domain reorientation at effect lower member inside magnetic domain domain wall in terrestrial magnetic field of magneto-mechanical effect, magnetoelastic energy increases the growth of offsetting stress energy.Therefore the magnetic field intensity of component inside can magnetic field intensity above Ground.Because metal inside exists multiple in-fighting effect, when loading, the region of stress concentration of component inside can remain particularly more outstanding under dynamic load and large deformation situation.Therefore for reducing stress energy, under the effect of magneto-mechanical effect, the reorientation of magnetic domain tissue can remain, and forms stray field at fault location, obtains the leakage field information geomagnetic field action, i.e. H from feeromagnetic metal surface
ptangential component H
p (x)there is maximal value.And normal component H
p (y)reindexing also has zero point.
Pick-up unit at present based on magnetic memory detection technology and exploitation mostly concentrates on petroleum pipe line, pressure vessel, the aspects such as rail, little in the application in construction steel structure field, and steel construction especially girder steel as main primary structure member at load, be easy under the impact of external environment condition and self-defect form region of stress concentration, be therefore necessary based on a kind of device detecting girder steel of magnetic memory detection technology exploitation.
