Description
Technical field
The utility model relates to a kind of surface profile detector, particularly relates to a kind of rock structural face surface profile detector, the quantitative measurement to rock structural face surface profile when being applicable to outdoor work or desk research in Geotechnical Engineering and association area.
Background technology
In rock mechanics, conventional roughness coefficient JRC describes the roughness of rock structural face, no matter be compared by Barton straight flange method determine or quantitatively determine roughness coefficient JRC, all require that the rock structural face surface outline curves recorded has higher degree of accuracy, this just needs a kind of instrument that can measure rock structural face surface outline curves more accurately." institute of Changjiang Academy of sciences report " the S1 phase in 1996 discloses a kind of surface roughness tester for rack, this instrument drives screw turns to make slide block along guide rail uniform motion by motor, the contact pilotage of the back springing type displacement transducer on slide block moves up and down along rock structural face surface the ordinate value gathering sampling point by pre-set frequency, the digitizing of rock surface contour curve is made by data Collection & Processing System, export the roughness coefficient JRC of rock structural face simultaneously, there is the advantage that data acquisition and procession automaticity is high.
But in use, the moment that contact pilotage contacts with structural plane, slide block still makes uniform motion under the drive of leading screw, and structural plane concave-convex surface rises and falls, coarse injustice, contact pilotage will inevitably be made to move be obstructed to cause the stressed change of slide block, cause ram speed irregular, equidistantly can not gather sampling point, this will cause the abscissa value of ordinate value and the expectation recorded not corresponding, can not portray the profile on rock structural face surface truly, the roughness coefficient JRC utilizing digitised points to calculate is also not accurate enough.
As can be seen here, prior art awaits further improving.
Summary of the invention
The utility model, for avoiding above-mentioned weak point of the prior art, provides a kind of rock structural face surface profile detector.
The technical scheme that the utility model adopts is:
A kind of rock structural face surface profile detector, comprise data Collection & Processing System and drive system two parts, described data Collection & Processing System is by back springing type displacement transducer, magnetostrictive displacement sensor, signal amplifier, A/D change-over panel and notebook computer composition, back springing type displacement transducer and signal amplifier, be connected with notebook computer after A/D change-over panel is linked in sequence, magnetostrictive displacement sensor comprises electronics storehouse, sounding rod and magnet ring, be connected with notebook computer via A/D change-over panel, described drive system contains DC synchronous steady speed motor, reducer casing, bearing, slide block, leading screw, guide rail, gauge head.
