Description
Technical field
The utility model belongs to surveying instrument, particularly relates to the slope measuring apparatus in a kind of highway construction.
Background technology
In construction, determine the gradient fast and accurately, can effectively save the engineering time, the stability of road surface or side slope is guaranteed.The instrument of measuring grade of side slope at present is a lot, and especially coarse measurement grade of side slope can be selected comparatively simple instrument or hand computation for use.As publication number is CN 2594759Y, the comparatively simple slope measuring instrument that the Chinese patent that name is called " a kind of grade rod " discloses; This utility model patent just is mainly used in the grade of side slope of measuring highway subgrade, and it equals according to a horizontal relatively corner of ruler and the principle of the corner of the relatively-stationary gravity pointer of this ruler is made.This grade rod is made up of ruler part and gradient mark dish.Use this grade rod, the grade of side slope that can only be used for the bigger roadbed of the gradient is measured, and this grade rod can only be measured the gradient of flat surface.
In existing, the slope requirement of most of side slope is coarse, but the gradient on road surface is less, require accurately, mostly be difficult to measure, especially pass through the road surface of bridge, the gradient is little, and road surfaces often has some radians, therefore, general gradiometer all is difficult to reach measurement requirement, and measurement data detects by an unaided eye, accuracy is low, can't tackle the slope measuring that zone, a certain road surface has microradian.
Summary of the invention
At the deficiency of above-mentioned existence, the utility model pin technical matters to be solved provides in a kind of highway construction novel, the gradient measurer that degree of accuracy is high.
The technical scheme that its technical matters that solves the utility model adopts is: a kind of gradiometer comprises mark dish, support and expansion link; Described support is made of vertically disposed fixed bar and fixed sleeving in parallel; Described mark dish is fixed on the support, and the mark dish is provided with gravitate and straight down pointer, and described fixed sleeving and expansion link mate mutually, and expansion link is enclosed within the fixed sleeving and with rack elasticity and is connected.
As preferably, this gradiometer also comprises the length records assembly, described length records assembly comprises spring and pressure transducer, and described expansion link is enclosed within the fixed sleeving and with pressure transducer and is connected by spring, and described pressure transducer is fixedly installed on the inside of support.Length records assembly mainly usefulness is the shortening length of record expansion link, to make things convenient for according to this data computation gradient.
As preferably, described expansion link is marked with scale.
As preferably, described fixed sleeving is the transparent casing that indicates scale.
As preferably, described fixed bar bottom is provided with vertically fixedly hoof, and described vertical fixedly hoof comprises a vertical bar and two elastic telescopicing rods, and described vertical bar and fixed bar are connected as a single entity.Vertically fixedly the effect of hoof is to make that fixed bar is more prone to keep standing on the road surface perpendicular to the surface level direction, ensures the degree of accuracy of follow-up measurement.
As preferably, this gradiometer also comprises electronic calculator, and counter calculates its data processing of record or input automatically apace a plurality of value of slope, and multi-group data is presented on its display screen.
As preferably, described expansion link has 5.Such gradiometer can be measured many group value of slope, can accurately calculate the radian on road surface, perhaps is used to the minimizing error of averaging.
The beneficial effects of the utility model: the utility model is designed to be gradient measurer novel in a kind of highway construction.This gradiometer is by being provided with many expansion links, and measuring height is poor, thereby calculates the gradient, therefore measure fast simple, by the average multi-group data or the influence of optionally omitting differential of the arc face, therefore, the measuring accuracy height.The designed gradiometer of the utility model can also pass through electronic calculator, directly a plurality of value of slope are calculated and show, perhaps do linear analysis, obtain mean value after rejecting data, significantly reduce the error that causes because of various factors, accurately measure the value of slope of approaching reality.

Fig. 2 is the gradiometer structural representation in use among Fig. 1.
Embodiment
Below by embodiment, and the technical solution of the utility model is further described in detail, but protection domain of the present utility model is not limited to this in conjunction with Fig. 1, Fig. 2.
Embodiment: as shown in Figure 1, a kind of gradiometer comprises mark dish 1, spring 7, pressure transducer 6, electronic calculator 4, support 3 and expansion link 9; Support 3 is made of vertically disposed fixed bar 12 and fixed sleeving in parallel; Mark dish 1 is fixed on support 3 upper left corners, and mark dish 1 is provided with gravitate and straight down pointer 2, also indicates scale on the dish of these pointer 2 indications, and scale can be-6 °, and-3 °, 0 °, 3 °, 6 ° are gone down by that analogy.Fixed sleeving and expansion link 9 mate mutually, and above-mentioned expansion link 9 has 5, and expansion link 9 all is enclosed within corresponding 5 fixed sleevings and with pressure transducer 6 and is connected by spring 7 elasticity, and described pressure transducer 6 is fixedly installed on the inside of support 3.5 expansion links 9 wherein all are connected with electronic calculator 4 by 5 pressure transducers 6 that spring 7 connects, and electronic calculator 4 also connects a locking press button 5, is used to lock transient data.
In addition, above-mentioned fixed bar 12 bottoms are provided with vertically fixedly hoof, and described vertical fixedly hoof comprises a vertical bar 10 and two elastic telescopicing rods 11, and described vertical bar 10 is connected as a single entity with fixed bar 12.Vertically fixedly the effect of hoof is to make fixed bar be more prone to stand in vertically the road surface, makes measurement more accurate.
During use, during not as measurement, 5 expansion links 9 of gradiometer are all equal with fixed bar 12 least significant ends.As shown in Figure 2, when this gradiometer is used to measure, gradiometer is shelved on the road surface, with hand the gradiometer right-hand member is pressed down, when making the pointer 2 of mark dish 1 point to 0 °, promptly pointer 2 and fixed bar 12 are all consistent with perpendicular to the surface level direction, show that support 3 levels place.Turn left from the right side like this, 5 expansion links 9 are extrusion spring 7 to some extent all, after spring 7 compressions masterpiece that equates is used for pressure transducer 6, according to Hooke's law, pressure transducer 6 just can be given electronic calculator 4 with digital signal transfers, can realize measuring expansion link 9 shortening length externally so fast.Owing to the horizontal range between 5 expansion links 9 and the fixed bar 12 is constant, these data are imported electronic calculator 4 in advance, when 0 ° of pointed, after pressing down locking press button 5, electronic calculator 4 just writes down the data that shorten length automatically, in conjunction with prior input value, just can calculate the gradient data between any two bars of permutation and combination between 5 expansion links 9 and the fixed bar 12 apace, and multi-group data is presented on the display screen of electronic calculator 4.
Many groups value of slope that such gradiometer is measured can accurately calculate the radian on road surface, perhaps does linear analysis, rejects and averages after the data reducing error, thereby guarantee the degree of accuracy of instrument.
In addition, this gradiometer can also manually be imported electronic calculator 4 with the scale value of 0 ° of needle deflection in the mark dish 1, can be with the value of slope correction of above-mentioned measurement.
