Abstract

The utility model relates to a profile meter, which is used for measuring and drawing the curve of the surface profile of the rock. The utility model is composed of a probe, a drawing pen, a balance block, and a fixed plate. The probe, the drawing pen, and the balance block are made into a whole, and the fixed plate is the other separated part. When used, the drawing pen is butted vertically and tightly with the fixed plate, and the probe is vertically fallen on the surface of the rock. The balance block is moved, the probe is rolled on the surface of the rock, and the drawing pen is used to draw the curve of the surface of the rock continuously on the fixed plate. A trace fixing balance shaft can be added, both ends of the trace fixing balance shaft are fixed on the fixed plate, and the balance block is sheathed on the trace fixing balance shaft. The utility model is used for continuously measuring and drawing the profile curve of the surface of the rock mass structure with arbitrarily position and arbitrary dimension.

Description

Profilo meter

The utility model is a kind of instrument that is used for the profiling object surface curved measurement.Being mainly used in the rock surface outline shape measures.Belong to the G01B field.

The commercial measurement of the equidistant intercepting of many both at home and abroad employings is at present drawn the rock surface contour curve.Equidistantly get a little, connecting also then successively, slyness then obtains contour curve.Nineteen eighty-two Canada B.Stimson has invented profile chi and model mould (referring to Rapid Field method for recording Joint Roughness ProfilesInt.J.Rock Mech.Min.Sei and Geomech.Abstr.Vol.19 on the basis of preceding method, 1982), its structure is 170 isometric pins to be listed in be clipped in then on the straight line on the microscler clip.During measurement rock is surveyed the face horizontal positioned, clip is unclamped then perpendicular to surface level in the plane that pin is formed, make the pin free-falling, be parked on the rock surface, the upper extreme point of pin roughly reflects a rock profile surface profile form, connect these upper extreme points and slick and sly successively, must contour curve.This method also is equidistantly to get a little, and just point is got closelyer, adopts this method precision can bigger raising but measure the restriction that length is subjected to the quantity of pin, can not draw arbitrary dimension, continuous rock surface contour curve.And, change actual form because artificial slick and sly, use inconvenient.

According to the problem that prior art exists, the utility model provides a kind of contour curve measurement to paint the survey instrument, can draw the rock surface contour curve continuously, and is easy to operate, improved precision.

The utility model is made up of probe 1, ruling pen 2, counterbalance weight 3, fixed head 4, in fact be divided into two independent parts, a part is made of one by probe 1, ruling pen 2, counterbalance weight 3, probe 1 is fixed on counterbalance weight 3 bottoms, ruling pen 2 is fixed on the side of counterbalance weight 3 other ends, probe 1 is vertical mutually with ruling pen 2 directional rays, and another part is exactly a fixed head 4.Two parts can not connect, and in use, the vertical rock structural face reference fields of fixed head 4 are placed, and counterbalance weight 3 parallel dead plates 4 are placed, and make probe 1 vertical reference face also drop on the rock surface, and ruling pen 2 vertically withstands on 4 of the fixed heads.

Probe 1 is made (being similar to the refill for ball-point pen nib) for being embedded with little ball on the feeler lever head, and little ball contact rock surface can roll along rock surface equably, guarantees stationarity preferably, can improve precision.Ball as required can be very tiny, guarantees the subtle change that reflects that rock surface rises and falls.Ruling pen 2 can be selected the pen of water outlet smoothness for use, and such as the printing pen even the pencil of PC-1500 computing machine, curve plotting reduces the error of getting in the slyness continuously.Counterbalance weight 3 is the solid content body of rectangle or other shape.Can adopt wooden, derby to make, guarantee in operating process, make ruling pen 2 and probe 1 that stable relative position be arranged all the time, remain in the plane that is parallel to initial plane.Fixed head 4 adopts thin and smooth plate, can be glass, and wooden even metal etc. made, and is used for solid support plotting paper.

The utility model also can increase certain mark balancing shaft 5 two parts are linked together.Decide mark balancing shaft 5 and be strip, the cross section is a rectangle, and two ends are fixed on the fixed head 4, with fixed head 4 spacing and parallel are arranged, and perpendicular with the plane of probe 1-counterbalance weight 3-ruling pen 2 compositions.Have rectangle narrow slit in the middle of the counterbalance weight 3 this moment, counterbalance weight 3 is enclosed within decide on the mark balancing shaft 5 and can move left and right and move up and down, and guarantees that counterbalance weight 3 moves in the track that is parallel to fixed head 4.

For fixed head 4 is steadily placed, can increase a base 6 in fixed head 4 bottoms.

The utility model is made of one probe 1, ruling pen 2, counterbalance weight 3, mobile balanced block 3, probe 1 just rolls at rock surface, the ruling pen 2 rock surface contour curve that on fixed head 4, draws continuously, easy to operate, improve precision, can draw the contour curve on the rock mass structure surface of any size continuously.

Fig. 2 is A-A ' cut-away view of Fig. 1.

Counterbalance weight 3 high 35mm-40mm of the present utility model, wide 6mm～8mm, long 15mm-20mm, probe 1 long 5mm-10mm, ruling pen 2 long 5mm-10mm.Can make other specification as required, be used for the Measuring Object surface outline curves.
