Description

A kind of wedge shape spring clearance gauge
Technical field
The present invention relates to a kind of clearance gauge, especially relate to a kind of wedge shape spring clearance gauge.
Background technology
In Rock And Soil, the opening width information in crack is the important evidence of its mechanical property of research and engineering stability.At present, opening width is less than to the Rock And Soil crack of 1cm, the general clearance gauge that adopts obtains its opening width parameter.But existing clearance gauge is in measuring process, and mainly through manually clearance gauge being filled in crack in Rock And Soil, then read opening width data, so normal reading clearance gauge parameter manipulation is extremely inconvenient; For fissure-plane and the Rock And Soil crack surveying face oblique, its opening width recorded is actual is depending on opening width (length that tested surface institute in crack cuts off out), instead of true opening width (vertical width between the wall of crack two); And artificial subjective factor is larger on measurement result impact in measuring process.
Chinese patent CN203240999U discloses the large conical plug gauge of a kind of surveying range, and the clearance gauge that this device contains four width divides chi, and the clearance gauge of different in width form can be used for the cracks aperture measuring different scales.But this clearance gauge is in measurement practice process, and the error caused by artificial subjective factor is comparatively large, causes the error of measurement result large; Parallel for two walls, and the crack in the survey face of being diagonal to, what it recorded is not that angle value is truly opened in crack.
Chinese patent CN202947635U discloses a kind of wedge-shaped feeler gauge, and this device mainly contains clearance gauge body and handle composition, clearance gauge body is distributed with the scale value that can characterize surveyed Fracture Width, directly can be obtained the opening width in surveyed crack by this scale value.But this clearance gauge is in measurement practice process, and still containing the comparatively big error that artificial subjective factor causes, during measurement, reading operation is also inconvenient, parallel for two walls, and the crack in the survey face of being diagonal to, what it recorded truly neither open angle value in crack.
Summary of the invention
Object of the present invention be exactly provide a kind of to overcome defect that above-mentioned prior art exists and measure accurately, measurement range is wide, convenient reading, calculating simple wedge shape spring clearance gauge.
Object of the present invention can be achieved through the following technical solutions:
A kind of wedge shape spring clearance gauge, for measuring the opening width in Rock And Soil crack, comprise main wedge and play wedge, described main wedge head is connected with bullet wedge head by rotating shaft, main wedge afterbody is connected with bullet wedge afterbody by the spring be arranged in the spring groove on main wedge, described main wedge comprises the rule be arranged in main wedge upper surface chi groove and the pressing board being arranged on main wedge lower surface, described rule is by chi rotating shaft and the pivot joint of chi groove, described pressing board is by pressing board rotating shaft and main wedge pivot joint, and it is outside that the angulation end of pressing board rotating shaft stretches out main wedge, which is provided with scale pin, described main wedge is provided with index dial at the angulation end place of pressing board rotating shaft, described chi rotating shaft is connected with pressing board rotating shaft by transmission rope, make chi rotating shaft when rotating, pressing board rotating shaft rotates backward with constant angular velocity.
Described chi rotating shaft and pressing board rotating shaft are equipped with spiral fashion cutting, and described transmission rope is fastenedly connected with chi rotating shaft and pressing board rotating shaft respectively by spiral fashion cutting.
Spiral fashion cutting in described chi rotating shaft is contrary with the spiral fashion cutting sense of rotation in pressing board rotating shaft.
Described transmission rope is rigid.
The range of described index dial is-90 degree ~ 90 degree, and its scale value is by increasing successively clockwise, and the groove of 0 angle value is parallel with main wedge lower surface.
When pressing board is vertical with main wedge lower surface, described scale pin points to 0 angle value.
Scale value on described rule is pressing board rotating shaft to the distance of main wedge wedge point and chi rotating shaft to the main ratio of distances constant of wedge wedge point and the product value of its physical length.
The range of described rule is more than or equal to 1cm, and scale spacing is less than 1mm.
Described main wedge afterbody is provided with hook, and described bullet wedge afterbody is provided with extension button, and described hook and extension button are hooked together when unmeasured.
Described main wedge head and bullet wedge head are lamellar wedge and longitudinal section is triangle.
Compared with prior art, the present invention has the following advantages:
One, measure accurately, adopt spring springing bullet wedge to measure Rock And Soil cracks aperture, efficiently avoid in the Rock And Soil that hardness is less, because artificial force is excessive, and cause measured value to be greater than the consequence of actual value.
Two, measurement range is wide, adopting the main wedge of tabular, making the main wedge back side be close to a wall in Rock And Soil crack when measuring, pressing board is flat on survey face simultaneously, avoiding existing clearance gauge because of artificial subjective judgement causes clearance gauge face to be diagonal to survey face, and causes measured value to be greater than actual value to obtain consequence.
Three, convenient reading, adopts rule to carry out amplification reading to cracks aperture, contributes to the convenient of reading operation, and effectively can improve the precision of reading.
Four, calculate simply, adopt the counter-rotational rule of synchronous constant angular velocity and by panel assembly, obtain the reading value e ' on rule, and the angle α that can directly read between both and main wedge back side normal, by formula e=e ' × cos α, the true opening width e in the crack that acquisition two wall parallels can be calculated.
