Description
Technical field
The invention belongs to the surveying instrument field, relate to the displacement measuring device of displacement field tests such as can be used for building, machinery, especially can realize displacement measuring device the accurate measurement of big displacement.
Background technology
At present, resistance-type displacement measurement sensor all is to use the linear resistance wire element both at home and abroad, the straight length of resistance wire promptly is the testing range of sensor, this makes such resistance-type displacement transducer because it is constructional former thereby can't realize bigger range, has limited its application in practice.
Summary of the invention
The purpose of this invention is to provide a kind of wire pulling and wire winding electric resistance type displacement pickup, can realize accurate measurement big displacement.
The object of the present invention is achieved like this: a kind of wire pulling and wire winding electric resistance type displacement pickup, backguy and resistance wire are coiled on two coaxial drums, the displacement of measuring point causes moving of backguy, thereby drive the rotation of drum, make resistance wire produce rotation, and make between resistance contact head and the resistance wire and produce relative displacement, cause the variation of relevant electric weight in the test bridge circuit, realize the purpose of mechanical shift electrical measurement.
Further, the coaxial connection between backguy wire spool and the resistance wire winding dish waits the rotation amount transmission, and the external diameter of backguy wire spool and resistance wire winding dish can be identical, also can be different;
Resistance wire in the test bridge circuit can be spiral yarn shaped;
Can connect by gear between backguy wire spool and the resistance wire winding dish, the amount of being rotated transmission according to a certain percentage, the external diameter of backguy wire spool and resistance wire winding dish can be identical, also can be different.
With the coaxial elastic recovery mechanism that is connected of backguy wire spool, for backguy provides restoring force.
Concrete, the resistance wire coiling that is connected in the test bridge circuit is fixed on the resistance wire winding dish, the traction steel wire termination is fixed on the measured point, the rear end is coiled on the steel wire wire spool, steel wire wire spool, resistance wire winding dish are connected with an elastic construction coaxial rigid, have one in the traction steel wire all the time by pretension that elastic mechanism transmitted.The displacement meeting of measuring point drives moving of traction steel wire, thereby cause the rotation of steel wire wire spool, drive the rotation of coaxial resistance wire winding dish then, have a resistance the silk with resistance contact head between relative slippage, cause the variation of voltage between interdependent node in the test bridge circuit, reach the purpose of electrical measurement displacement.
Owing to adopt such scheme, can effectively realize the accurate measurement of relatively large journey, utilize the structural form of ressitance spiral, can realize 0.1 to 20 meter range easily, this will be well beyond traditional line shape resistance wire displacement transducer usually less than 0.6 meter range.
Description of drawings
Fig. 1 is the test electric bridge principle schematic of an embodiment of the present invention.
Fig. 2 is the diagrammatic cross-section of the backguy resistance-type displacement transducer of an embodiment of the present invention.
Fig. 3 is the 1-1 diagrammatic cross-section that indicates on Fig. 2.
Embodiment
See also Fig. 1-3, an embodiment of the present invention comprises among the figure: resistance wire 1, traction steel wire 2, resistance wire winding dish 3, steel wire wire spool 4, turning axle 5, slider 6, contact guide rail 7, elastic mechanism 8, traction steel wire termination 9, terminal box 10, data line plug receptacle 11, shell 12, fixed handle 13.
Fig. 1 is a test electric bridge schematic diagram of the present invention.R ' is corresponding to the ressitance spiral among Fig. 21 among the figure.Go up when mobile at R ' when slider, can cause the variation of voltage between 2 of the BD in the test electric bridge, thereby realize the transformation of mechanical displacement to electric weight.
In sectional view shown in Figure 2, resistance wire 1 coiling is fixed on the resistance wire winding dish 3, traction steel wire 2 one ends link to each other with the measured point by traction steel wire termination 9, the other end is coiled on the steel wire wire spool 4, resistance wire winding dish 3, steel wire wire spool 4 and elastic mechanism 8 are connected on the turning axle 5, elastic mechanism 8 can offer 2 one lasting pretensions of traction steel wire, resistance slider 6 remains contact with resistance wire 1, and move along contact guide rail 7 under can driving at the lateral pressure of thread groove on the resistance wire winding dish 3, resistance wire 1 and slider 6 are formed test electric bridge by lead and terminal box 10 with outside pertinent instruments, and tool housing 12 is fixed by fixed handle 13.When carrying out displacement measurement traction steel wire termination 9 is connected with the measured point, the displacement meeting of measuring point drives traction steel wire 2 motions and makes steel wire wire spool 4 and turning axle 5 rotations, thereby drive 3 rotations of resistance wire winding dish, make resistance wire 1 with producing relative motion between the slider 6, cause the variation of relevant electric weight in the test bridge circuit, by measurement, and, realize electrical measurement to displacement according to the corresponding relation that electric weight and displacement change to this electric quantity change.Backguy steel wire wire spool 4 and resistance wire winding dish 3, between also can connect the amount of being rotated transmission according to a certain percentage by gear.
The above-mentioned description to embodiment is can understand and apply the invention for ease of those skilled in the art.The person skilled in the art obviously can easily make various modifications to these embodiment, and needn't pass through performing creative labour being applied in the General Principle of this explanation among other embodiment.Therefore, the invention is not restricted to the embodiment here, those skilled in the art should be within protection scope of the present invention for improvement and modification that the present invention makes according to announcement of the present invention.
