Abstract
The utility model discloses a slop measuring device, which comprises a casing body and a graded wheel, a viewfinder is arranged on the casing body, the viewfinder is marked with reference position, the graded wheel is pivoted in the casing body, the center of gravity deviates the centre of gyration, and scale marks are indicated on the graded wheel. The slop can be measured by the utility model in a direct way, measuring process is simple, slope value can be read directly, the conversion is not needed, and the error of measurement is reduced.
Description
Technical field
The utility model relates to the measuring equipment field, is specifically related to a kind of gradient measurer.
Background technology
Under many circumstances, people need carry out slope measuring, for example, in traffic accident analysis, often will take all factors into consideration factors such as road conditions, at this moment just need measure the on-the-spot gradient.Generally, people to obtain value of slope be to pass through indirect mode.Promptly measure the difference in height between 2 and the air line distance of point-to-point transmission at first respectively, and then utilize trigonometric function to convert, thereby obtain concrete value of slope.In use there are the following problems for this slope measuring mode: one, adopt indirect metering system, measuring process is complicated.Two, measurement result need obtain by conversion, has increased measuring error.
Summary of the invention
For gradient measuring process in the solution prior art is complicated, the problem that measuring error is big, the utility model provides a kind of gradient measurer, and it carries out slope measuring with direct mode, and is easy to operate, and measuring error is little.
The technical scheme that its technical matters that solves the utility model adopts is: utilize a housing and a degrees wheel, form a gradient measurer, housing is provided with form, it is marked with the reference position, degrees wheel is hubbed in the housing, its deviation of gravity center centre of gyration, and its subscript is shown with scale.Because degrees wheel is for being pivoted, it can freely rotate.During use, this gradient measurer is placed on any measuring position, because the deviation of gravity center centre of gyration of degrees wheel, degrees wheel will make centre of gravity place be positioned at centre of gyration below all the time under action of gravity.The reference position that indicates on the housing is with the difference of the measured place gradient, and the vertical position of the relative degrees wheel centre of gyration of meeting departs from certain angle, and this angle is the gradient that institute's location is put, and this value of slope can be read by the scale on the degrees wheel.
The utlity model has following beneficial effect: one, the indicated angle value in reference position is the value of slope of measuring position on the housing, realized carrying out slope measuring with direct mode, measuring process is simple, two, value of slope can directly be read from form, need not convert, reduce measuring error.

Embodiment
To embodiment shown in Figure 3, this gradient measurer comprises housing 1, degrees wheel 4 at Fig. 1, and housing 1 is provided with form 3, and it is marked with the reference position, and degrees wheel 4 is hubbed in the housing 1, its deviation of gravity center centre of gyration, and its subscript is shown with scale.
Form 3 can see that from form 3 scale on the degrees wheel 4 shows for being located at an opening on the housing 1, and the reference position can be for being marked on a near mark this opening.Form 3 can be arranged on the end face of housing 1, also can be arranged on the housing side, and corresponding change is done with form 3 positions in the position of degrees wheel 4 high scales.In the present embodiment, form 3 is arranged on housing 1 end face, studs with transparent material on it, and the reference position is mark or is inscribed in a datum line 8 on the transparent material, is provided with illuminating lamp 13 near the form place in housing, with convenient reading when light is dark.This illuminating lamp 13 also can adopt luminotron to replace, and realizes said function.
In the present embodiment, degrees wheel 4 is hubbed on the transverse axis 5 by a rolling bearing 2, and this transverse axis 5 is fixedly arranged in the housing 1, have scallop hole on the degrees wheel, it matches with a weight, and the weight cross section is fan-shaped, its tip is towards the centre of gyration, and arc tips is away from the centre of gyration.
Degrees wheel can have multiple mode when implementing, for example, for making the degrees wheel deviation of gravity center centre of gyration, can reduce material in degrees wheel one side.Degrees wheel can be fixedly installed on the transverse axis, is hubbed on the housing indirectly by transverse axis again.
During use, as reference field, place it in any measuring position with the bottom surface of this gradient measurer, because the deviation of gravity center centre of gyration of degrees wheel, degrees wheel will make centre of gravity place be positioned at centre of gyration below all the time under action of gravity.The reference position that indicates on the housing is with the difference of the measured place gradient, and the vertical position of the relative degrees wheel centre of gyration of meeting departs from certain angle, and this angle is the gradient that institute's location is put, and this value of slope can be read by the scale on the degrees wheel.
Fig. 4,5 is depicted as second kind of embodiment of the present utility model.Different with above-mentioned first kind of embodiment is, in this embodiment, gradient measurer also comprises the benchmark support, and this benchmark support is elongated.When measuring the whole gradient in a big way, the benchmark support is placed on the measuring position, again gradient measurer is placed on this benchmark support, can effectively enlarge measurement range.
In the present embodiment, the benchmark support adopts unitized construction.Each benchmark support 10 1 end is provided with spliced eye 12, and the other end is provided with between the spliced eye 12 of connection-peg 11, two benchmark supports 10 correspondences and the connection-peg 11 and can cooperatively interacts.The benchmark support also can adopt other fabricated structure, as telescopic structure, can realize same function.
