Abstract
The utility model relates to a crown measuring frame which is used for assistant measuring the crown of paving. The crown measuring frame is composed of a base, a support frame of the base, a crossbeam of the support frame the upper end, a swing bar with a weight hinged by a pin and a crossbeam, a dial gauge fixing bracket arranged on the crossbeam. The utility model can directly measure the crown value of paving and has the advantages of precise datum, simple operation and convenient carry.
Description
The utility model is a kind of road camber measurement bay, is the device of assisting to measure crown of pavement.
Because the camber of highway pavement itself is less, generally in 1%～3% scope, therefore require accurately to measure.Crown of pavement is measured and is often finished by means of spirit-leveling instrument at present, and measured data are comparatively accurate, but needs the instrument of usefulness more, not portable, and needs two people's conjunction measurings, and measuring speed is also slower.Sometimes utilize three meters rulers and down scale chi conjunction measuring, but the data that record are accurate inadequately.And the application number of on January 1st, 86 bulletin is the patented claim of CN85200657, has designed a kind of device of the measurement pitch angle of being made up of two supports that are hinged, line bob, index dial etc., and this design can not be satisfied accurate Testing requirement.More than three kinds of methods of measuring crown of pavements all need to obtain the camber value by conversion, make work comparatively loaded down with trivial details.
The purpose of this utility model is, design a kind of simple to operate, the precision height, the gauger can directly obtain camber value and portable road camber measurement bay.
The utility model is finished like this.The fork of lower end band one weight that it is hinged by the crossbeam of the support on base, the base, support upper end, by bearing pin and crossbeam and the dial gauge fixed mount that is installed on the crossbeam are formed.One air level is arranged on the base.The dial gauge fixed mount is made up of the support bar and the dial gauge fixture block on it that are fixed on the crossbeam.Fork in the self-marketing axially is marked with and the corresponding range scale of the dial gauge number of degrees.
Below in conjunction with accompanying drawing the utility model is described in detail.
Fig. 1 is equipped with the front view of the present utility model that the part of dial gauge is cutd open;
Fig. 2 is the left view of Fig. 1;
Fig. 3 is the vertical view of Fig. 1;
Fig. 4 is the structural drawing of the utility model support bar fixture block part.
Wherein, 1-base, 2-air level, 3-support, 4-crossbeam, 5-bearing pin, 6-fork, 7-dial gauge fixture block, 8-dial gauge, 9-screw, 10-support bar fixture block, 11-support bar, 12-weight, 13-groove, 14-screw.
The utility model is made up of base (1), air level (2), support (3), crossbeam (4), fork (6) and the hammer (12) that hangs down.The upper bottom surface of base (1) is parallel with bottom surface, and an air level (2) is housed on the upper surface.Support (3) is made up of contour two parts, and is separately fixed on the base (1) by bolt.Respectively there is a hole the two-part upper end of support (3), crossbeam (4) is fixed on the support (3) by this hole by two bolts, and makes it parallel with base (1).Crossbeam (4) is a rectangle frame, and there are two relative holes at it does not contact both sides with support (3) middle part, and bearing pin (5) passes two holes, and vertical with the both sides of its contacted crossbeam (4).Bearing pin (5) mid point is connected with fork (6) rigidity, and the part of fork (6) exceeds bearing pin (5).Weight (12) rigidity is connected the lower end of fork (6), and fork (6) can swing by relative together crossbeam with bearing pin (5) (4) with weight (12).One outshot is arranged at the bottom at the crossbeam (4) of fork (6) one sides, and a screw mating holes is arranged on it, and is by screw (14) that support bar fixture block (10) is fixing.Support bar fixture block (10) clamping support bar (11), and make it vertical with surface level.For preventing that support bar (11) from serving as that axle deflects with screw (14), on contacted of the outstanding downwards part of crossbeam (4) and the support bar fixture block (10) groove (13) is arranged, the corresponding with it position of support bar fixture block (10) has a projection to embed groove (13).Dial gauge fixture block (7) is being fixed by screw (9) in the upper end of support bar (11), and dial gauge (8) is fixed on the utility model by dial gauge fixture block (7).Unclamp screw (9), dial gauge (8) can serve as a last deflect with screw (9) with dial gauge fixture block (7), unclamps screw (14) then with the moving up and down of support bar (11), and can adjust the height of dial gauge (8).The push rod of dial gauge (8) touches and leans against fork (6) and exceed on the part of bearing pin (5).When the utility model measurement road camber is spent, fork (6) is in the effect deflect of weight (12) and all the time perpendicular to surface level, its top acts on the push rod of dial gauge (8), makes a certain scale of pointed of dial gauge (8), thereby reflects the size of crown of pavement.To obtain accurate data in the use, at first will return to zero.Utilize air level (2) to determine that the utility model is on the surface level, at this moment, fork (6) is vertical with crossbeam (4), adjusts the position of dial gauge (8), makes its pointed zero.Because dial gauge (8) touches the position difference that leans against fork (6), effect varies in size the same angle of fork (6) deflection to dial gauge (8), according to accurate Calculation, go up at fork (6) and to make progress respectively from itself and bearing pin (5) connecting place that the value of indicating is 0,1,2 ... scale.Mobile support bar (11) can make the push rod of dial gauge (8) point to different scales, and these scales have reflected the range of dial gauge (8), and the scale value of push rod indication is big more, and the range of dial gauge (8) is just more little, thereby the value that records is accurate more.As, when the scale of push rod indication was 1, if the value of reading of dial gauge (8) is 10, then the camber on the expression road surface of surveying was 1%; The value of reading is 25 o'clock, and the expression camber is 2.5%.When referring to that bar points to 2, if dial gauge (8) value of reading is 20, then crown of pavement is 1%.When measurement had the camber on road surface of compressional wave, fork (6) and weight (12) deflected on its direction that can not freely swing under action of gravity, thereby hinder it to freely swing.Make it adapt to the gradient because crossbeam (4), at this moment can reverse crossbeam (4) by two bolt, guarantee fork (6) and weight (12) along the smooth deflection of road camber direction, thereby record accurate data.
The utility model has designed a kind of crown measuring frame, and the camber of its energy clamping dial gauge road pavement is done accurate measurement, and can obtain more intuitively the camber value, and it has simple to operate, and volume is little, characteristics easy to carry.
