Description
Technical field
The present invention relates to a kind of rock wear-resistant tester, belong to rock property experimental technique field.
Background technology
In order to test the pen. of rock, what adopt in the world is mainly just (CERCHAR) abrasion test of plucked instrument, its method is: be the weight that covers 7Kg on the draw point of 90 degree by cone angle, needle point acts on the smooth surface of rock, along continuous straight runs, with the speed motion 10mm of 10mm/min, takes off draw point, test needle point width value, unit is 0.1mm, is the proper abrasion resistance index of plucked instrument.The proper abrasion resistance index of plucked instrument is very important design objective in tunnelling and mining, but the domestic testing tool that there is no at present the proper abrasion resistance index of plucked instrument.
Although the proper abrasion test of plucked instrument is widely used rock abrasivity method of testing, conventional testing tool still has many weak points in the world: draw point moves horizontally speed control and relies on manually, has increased the otherness of experiment; After test, draw point needle point width measure relies on micrometering, and precision is limited and inconvenient; Cannot record rock dent characteristic, be unfavorable for Wear Resistance Mechanism analysis; Power value and shift value can not record draw point tangential movement time, be unfavorable for Wear Resistance Mechanism analysis; Can not dynamically recording experimentation data, be unfavorable for experimentation analysis.
At home, have rock anti-erosion test apparatus for the instrument of rock anti-erosion test, the draw point level that it can obtain in experimentation is inhibition, power value, draw point abrasion length value, the rock indenture degree of depth; Can facilitate and obtain accurately the proper wear-resisting quality of plucked instrument; Can precisely control draw point tangential movement speed and displacement.And its shortcoming is can not record draw point pin and enter the change in displacement process of rock; Only test the wear-resisting situation of rock along certain straight line, and the wear-resisting situation of failing to test rock burnishing surface.
Summary of the invention

Above-mentioned rock pen. test department also comprises stay, and stay is arranged on fixed mount inferior support and fixed mount are linked together and make it fixing.
The rolling pearl of above-mentioned many vertical setting of types is symmetrically arranged four rows.
The present invention has following beneficial effect:
1, when having realized the pen. on test rock line real-time testing the stock removal of rock transverse plane, to more fully analyze the relation of rock hardness and its anti-wear performance.The scope of rock end face abraded quantity representative is greater than the line scope of pen., stronger to rock representativeness.
2, the experimental provision of test rock transverse plane stock removal can be tested a certain amount of rock sample M of grinding
1required time S
1, also can measure certain hour S
2in the big or small M of rock sample stock removal
2.
3, realized the uniform rotation of linear uniform motion and the mill of draw point.
4, the fixing loading of the first weight 10 and the second weight 8 is ensured that the weight of weight is carried on the first scroll chuck 11, needle-valve 6 completely, in whole process of the test, realizing weight loads, the gravity of counter poise is adjustable, its gravity will be much larger than rock sample quality, thereby the gravity causing while making rock abrasion certain depth reduces and can ignore, the rock good to wearing quality, for increasing the sensitivity level of test data, can strengthen weight and improve the amplitude of variation of data reflection.
5, on rock is axial, add displacement meter (replaceable read table 13 and inductance water proof flexible displacement meter 14 are realized intelligence and measured in real time), can realize the real-time measurement of face degree of abrasion, in the time encountering the axial lithological change of rock, this degree of abrasion can quantitatively characterizing different lithology wearing quality, degree of abrasion gradual change rule in the axial direction also can be measured the homogeneity of rock.
