Description
The utility model relates to the geodetic surveying technical field, particularly the measurement of dip angle technology.
Obliquity sensor is mostly based on the principle of work of " pendulum ", the characteristic of promptly utilizing " pendulum " in the gravity field to try hard to remain on vertical designs various inclinators, potentiometer formula, strain-type, condenser type, inductance type obliquity sensor all are to utilize the solid pendulum inclination angle to be transformed into the variation of corresponding resistance, strain, electric capacity or inductance value, pass through analog signal processing circuit, output voltage signal or frequency signal, with respect to digital sensor, have that temperature is floated, drift and a problem such as non-linear.
Common pendulum-type inclinator only is useful for static measurement, and correct reading must wait pendulum stable, needs for a long time.Continuous coverage is carried out at the inclination angle that changes, must be provided damping to pendulum, elimination freely swings as early as possible, common method is to adopt silicone oil damping and air damping, the former ratio of damping reduces bigger with the rising of temperature, the latter makes the structure of inclinator become very complicated, and requirement on machining accuracy is higher.Chinese patent CN 2031913U proposes the cart type measurement mechanism of a kind of measurement gauge, level (left and right sides rail discrepancy in elevation), its mono-pendulum type inclinator has used air damping, its shortcoming is that piston may rock or tremble to contact with housing and influences correct measurement because of front and back, and the structure of this system is more complicated also.
The purpose of this utility model provides a kind of digital inclinator, and it can solve effectively, and the sensor temperature is floated, drift and nonlinear problem, for single pendulum provides effective damping, realizes reading fast and accurately.
The purpose of this utility model can realize with following technical scheme: digital inclinator is made up of the electron plate of shell, base, portal trestle, rotary encoder, single pendulum, U-iron and permanent magnetic steel, band nixie display and signal accessory power outlet.Portal trestle is fixed on the base, permanent magnetic steel is arranged in the medial surface of U-iron, form the magnetic circuit of band air-gap, scrambler is connected with electron plate by connector, it is characterized in that: scrambler is fixed on the portal trestle crossbeam, and U-iron is fixed on the base, the single pendulum part is all made with non-magnetic conductive metal, fork upper end is fixed on the shaft extension of scrambler, and the fork lower end connects tabular pendulum, tabular pendulum all the time some in the middle of the magnetic circuit air-gap.When base tilted, the single pendulum gravitate produced swing, drove the scrambler axle and rotated and produce the pivot angle digital signal, delivered to electron plate or computing machine and handled and draw pivot angle numerical value.Meanwhile, pendulum is because of cutting magnetic line, and portion produces vortex flow within it, forms damping of oscillations, because eddy current is directly proportional with swing speed, does not influence the final position of pendulum, the remaining swing of just very fast elimination.The structure that produces the magnetoelectricity eddy current damping has two relative simple proposal, and one of scheme is: the magnetic circuit air-gap is horizontally disposed, and pendulum is a watt shape plate, and it is fixing that it and fork are 90 degree, and center of circle of arc-shaped surface is on axis of oscillation about it.Two of scheme is: the magnetic circuit air-gap arranges that vertically pendulum is dull and stereotyped, and it is vertical with axis of oscillation.Two schemes are compared, and scheme two is simple in structure, and scheme one structure is complicated slightly, but can also produce the damping that prevents the single pendulum vibration in balance staff direction (trolley working direction), and are favourable to the work of pendulum bearing, so the utility model preferred version one.Scrambler of the present utility model should have less starting moment, rotary resistance and higher angular resolution, the occasion of having relatively high expectations for damping characteristic, the feature that need change according to the inclination angle is carried out complex optimum to the material and the thickness of the length of pendulum and quality, air-gap flux amount, pendulum.The also available hot-wire coil on U-iron of the magnetic circuit of above-mentioned in addition generation eddy current forms, and without permanent magnetic steel, the adjusting of damping this moment size just can realize by Current Regulation, and is convenient flexible.Producing the magnetoelectricity eddy current damping can also need only and guarantee that some is positioned in the middle of the magnetic circuit air-gap tabular pendulum all the time with other organization plan, cutting magnetic line, and do not get final product with other parts friction.
The utility model compared with prior art, advantage is: measurement range is wide, precision is high, good linearity, the good stable reading of damping is fast, interference rejection ability is strong, and no drift, temperature are floated and nonlinear problem.Be particularly suitable for the occasion at accurate continuous coverage inclination angle, as be installed on the detection pusher gear of the railway track left and right sides discrepancy in elevation.Also can be used for the continuous on-line measurement at airport pavement, highway pavement inclination angle.

Fig. 1 is an inner structure front view of the present utility model.
Fig. 2 is structure of the present utility model (A-A) sectional view.
It below is most preferred embodiment of the present utility model.
Fork 4 and tabular pendulum 5, U-iron 6, permanent magnetic steel 7 and shell 8 that the numeral inclinator is made by base 1, portal trestle 2, optical rotary encoder 3, by non-magnetic conductive metal material are formed.Fix a portal trestle 2 on base 1, scrambler 3 is fixed on the crossbeam of portal trestle 2, under the scrambler 3 U-iron 6 is being fixed on the base 1, fixes one or two permanent magnetic steel 7 in the inboard of U-iron 6 ends, forms the magnetic circuit of band air-gap.The upper end of fork 4 is fixed on the shaft extension of scrambler 3, its lower end fixedly connected watt of shape plate pendulum 5, the center of circle of pendulum arc-shaped surface about in the of 5 on axis of oscillation, with the friction of other parts, and pendulum 5 some is positioned in the middle of the magnetic circuit air-gap all the time.
When base 1 tilted, the single pendulum gravitate produced swing, and the axle that drives scrambler 3 rotates and produces the pivot angle digital signal, delivered to electron plate or computing machine and handled and draw pivot angle numerical value.Meanwhile, the magnetic line of force of tabular pendulum 5 cutting magnetic circuit air-gaps, portion produces vortex flow within it, forms the power that stops swing, because eddy current is directly proportional with swing speed, does not influence the final position of pendulum, the remaining swing of just very fast elimination.Pendulum 5 and fork 4 are 90 degree to be arranged and not only can produce damping at swaying direction, can also go up to produce in axis of swing direction (direction that go-cart is advanced) to prevent the damping trembleed, highly beneficial to the work that improves pendulum bearing.
