Abstract
A displacement sensor measurement range expanding device comprises a casing, a variable-speed shaft and a power output shaft. The variable-speed shaft and the power output shaft are connected through a clamping groove, a first wire wheel and a second wire wheel are arranged on the variable-speed shaft, and wire ropes are tied on the first wire wheel and the second wire wheel; and a coil spring is fixed on the power output shaft, and the outer diameter of the first wire wheel is larger than the outer diameter of the second wire wheel. The device which can expand the measurement range of the original small measurement range displacement sensor converts large displacement to small displacement according to transmission ratio by use of the principle of a speed reducer, so as to achieve expansion of the measurement range of the small measurement range displacement sensor. Due to the restoring force of the original displacement sensor and the accessory coil spring force, the normal operation of the system and the accuracy of measured data are ensured.
Description
Technical field
The utility model relates to a kind of range multiplying arrangement of displacement transducer, especially a kind of device that can amplify resistance-type, type vibration wire displacement transducer range.
Background technology
At present, known displacement transducer, general resistance principle or two kinds of forms of vibratory string principle of adopting, but, no matter be the form that resistance principle or vibratory string principle mostly adopt guide rod,, add the restriction of installing space owing to be subjected to the restriction of structure, it is oversize that guide rod all can not be done, so the range of displacement transducer is relatively all smaller.Though these displacement transducers can guarantee measuring accuracy, but can't meet the demands in the occasion that much needs the wide range test.
The utility model content
The purpose of this utility model provides a kind of range multiplying arrangement of displacement transducer, after this device connects displacement transducer, can be under the situation that does not change original displacement transducer, the range of displacement transducer is amplified several times, thereby finish the test of great-scale displacement.
For reaching above purpose, solution of the present utility model is:
A kind of displacement transducer range multiplying arrangement comprises housing, variable-speed shaft and power output shaft, and variable-speed shaft is connected with power output shaft, and variable-speed shaft is provided with first line wheel, second line wheel, and first, second line wheel is gone up system wire rope; Be fixed with wind spring on the power output shaft.
Be connected by draw-in groove between described variable-speed shaft and the power output shaft.
Described first line wheel, second line wheel rotate around same axis with variable-speed shaft.
Described first line wheel external diameter is taken turns greater than second line.
The wire rope of described first, second line wheel stretches out outside the housing.
The two ends of described variable-speed shaft and power output shaft are equipped with bearing.
Cylindrical one end of described wind spring is fixed on the housing, and center one end of wind spring is fixed in the groove of power output shaft, and power output shaft is rotated under the effect of wind spring back stretch.
The wire rope that first line wheel is gone up system links to each other with testee outside housing, and the wire rope that second line wheel is gone up system links to each other with displacement meter outside housing.
The wire rope that wind spring is gone up system for first line wheel provides restoring force, and displacement is counted second line wheel and gone up the wire rope of system restoring force is provided, and keeps two steel wires all to be in the state of tightening all the time, thereby has guaranteed the rotation ratio of device strictness.After testee moves certain displacement, the less displacement after displacement meter will stretch out and dwindle by strict ratio of gear, thus reached the purpose of this utility model.
Owing to adopted above technical scheme, the utlity model has following beneficial effect: the bigger displacement of displacement transducer test that can utilize little range, simultaneously, do not change the structure of original displacement transducer, can very simple realization be connected or separate with existing displacement transducer, Not a hair of one's head shall be touched hinders original displacement transducer.Gear of the present utility model and restoring force mechanism separate design are easy for installation and removal.

Embodiment
Below in conjunction with the accompanying drawing illustrated embodiment the utility model is further described.
In Fig. 1, line wheel 2, little line wheel 3 are installed on the variable-speed shaft 4 by center pit separately greatly, and two lines wheels center on same axis rotation with variable-speed shaft.On two lines wheel is respectively to have wire rope 6 to stretch out housing 1, and wind spring 7 is fixed on the power output shaft 8, and variable-speed shaft 4 and power output shaft 8 link together by draw-in groove, and bearing 5 is installed in the two ends of variable-speed shaft 4, power output shaft 8.The rotating ratio of size line wheel has determined the enlargement factor of displacement transducer range multiplying arrangement, cylindrical one end of wind spring 7 is fixed on the shell 1, center one end of wind spring 7 is fixed in the groove of power output shaft 8, power output shaft 8 can be rotated under the effect of wind spring back stretch, the big line wheel 2 that is installed on the power output shaft 8 also can and then rotate, thereby for wire rope 6 provides restoring force, for the wire rope 6 on the big line wheel 2 provides restoring force, displacement transducer 11 self restoring force provides restoring force for the wire rope 6 on the little line wheel 3, thereby make the wire rope 6 in the mechanism be in the state of tightening all the time, guarantee strict rotating ratio, guaranteed the operate as normal of system and the accuracy of test data.
In Fig. 2, big line wheel 2 wire rope 6 that stretch out displacement transducer multiplying arrangement 10 housings 1 are connected on the testee 9, because the effect of wind spring 7 makes this root wire rope 6 be in tensioned state all the time; Little line wheel 3 wire rope 6 that stretch out displacement transducer multiplying arrangement 10 housings 1 are connected on the displacement transducer 11, because the restoring force of displacement transducer 11 itself makes this root wire rope 6 be in the state of tightening all the time; Displacement transducer multiplying arrangement 10 is fixed together with displacement transducer 11.After a certain amount of displacement takes place in testee 9, with big line wheel 2 wire rope that the link to each other 6 corresponding length of can stretching out or withdraw thereupon, according to rotating ratio, can withdraw thereupon or stretch out corresponding less length with little line wheel 3 wire rope that link to each other 6, the displacement transducer 11 that the is attached thereto corresponding less displacement that to stretch out or to withdraw, be that this displacement changes into less displacement through displacement transducer multiplying arrangement 10 by rotating ratio, thereby amplified the testing range of original displacement transducer.
The above-mentioned description to embodiment is can understand and use the utility model 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 utility model is not limited to the embodiment here, and those skilled in the art should be within protection domain of the present utility model for improvement and modification that the utility model is made according to announcement of the present utility model.
