Abstract
The utility model relates to an anti-pollution displacement sensor. The anti-pollution displacement sensor comprises a displacement sensor outer sleeve, a base, a magnetic head seat, a magnetic head, a magnetic scale, an electric cable, protective cylinder sleeve and springs, wherein the displacement sensor outer sleeve is fixedly connected with a rolling mill automatic gain control (AGC) hydraulic cylinder, the base is arranged on the lower portion of the displacement sensor outer sleeve, the magnetic head seat, the magnetic head, the magnetic scale and the electric cable are arranged in a displacement sensor cylinder body, the protective cylinder sleeve is connected with the displacement sensor outer sleeve in a sliding mode, and the springs are arranged in the displacement sensor outer sleeve and the protective cylinder sleeve. The anti-pollution displacement sensor is characterized in that ventholes with thread are formed in the base, and the ventholes are communicated with an outer nitrogen gas pipeline. The anti-pollution displacement sensor has the advantages that the service life of the displacement sensor is effectively prolonged, the failure rate of the displacement sensor is reduced, and the reliable operation of a rolling mill is guaranteed.
Description
Technical field
The utility model relates to a kind of sensor, especially a kind of antipollution displacement transducer with the AGC position of the milling train bottom of flexible stroke of being convenient to use under adverse circumstances.
Background technology
The rolling mill AGC position sensor belongs to the critical elements of milling train, it is comprised of detecting element and protection cylinder sleeve, the detecting element magnetic head is fixed on the inside of protection cylinder sleeve, magnetic scale passes magnetic head and follows outside mechanical organ action, and the generation signal of telecommunication, can detect in real time the physical location of AGC hydraulic cylinder bar, calculate the actual (real) thickness of rolled plate.The accuracy of detection of AGC position sensor is directly determining the thickness control accuracy of milling train, is determining the lumber recovery of steel plate.Because residing work under bad environment is full of steam and oil on every side.When the exterior mechanical element rises, because following, the effect magnetic scale of spring moves up, form partial vacuum in the cylinder body this moment, locates extraneous moist empty vapour and oil are sucked in the cylinder body by cable tube joint or telescopic tube etc., forms ponding, and magnetic scale is got rusty.Because magnetic scale, head gap are very little, day by day serious along with the magnetic scale scale causes the magnetic scale action not smooth, makes thickness measure deviation occur, affects product quality.
Summary of the invention
The purpose of this utility model is to provide a kind of antipollution displacement transducer of being convenient to produce malleation in cylinder body, in order to prolong the service life of sensor, reduces the fault rate of sensor.
The purpose of this utility model is to realize like this.
According to antipollution displacement transducer of the present utility model, comprise the displacement transducer overcoat that is fixedly connected with the rolling mill AGC hydraulic cylinder, the base that is arranged on displacement transducer overcoat bottom, be arranged on magnetic head seat, magnetic head, magnetic scale and displacement transducer cable in the displacement transducer cylinder body, the protection cylinder sleeve that is slidingly connected with described displacement transducer overcoat and be arranged on the displacement transducer overcoat and the protection cylinder sleeve in spring, it is characterized in that having threaded passage at described base, this passage is communicated with outside nitrogen pipeline.
The utility model has the advantages that: owing to having taked technique scheme, so that displacement transducer in the course of the work, constantly in the displacement transducer cylinder body, be filled with nitrogen by the threaded passage of opening on the base, make displacement transducer in the course of the work, constantly be filled with nitrogen in the cylinder body and form malleation, guarantee the drying in space in the displacement transducer cylinder body, prevent that magnetic scale from getting rusty.In addition, because nitrogen has not oxidisability, can prevent that the detecting element of displacement transducer is subject to oxidation.
Description of drawings
Fig. 1 is the structural representation of the utility model displacement transducer.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is described in further detail.
As shown in Figure 1, antipollution displacement transducer of the present utility model, comprise the displacement transducer overcoat 2 that is fixedly connected with the rolling mill AGC hydraulic cylinder, the base 1 that is arranged on displacement transducer overcoat 2 bottoms, be arranged on magnetic head seat 3, magnetic head 4, magnetic scale 5 and displacement transducer cable 9 in the displacement transducer cylinder body, the protection cylinder sleeve 6 that is slidingly connected with described displacement transducer overcoat 1 and be arranged on displacement transducer overcoat 2 and protection cylinder sleeve 6 in spring 8, it is characterized in that having threaded passage 10 at described base 1, this passage 10 is communicated with outside nitrogen pipeline.
The large I of passage 10 of the present utility model designs according to the nitrogen pipeline diameter, is generally 4～8mm.
Label 7 among the figure is sensor and hydraulic cylinder contact jaw, when contacting with the rolling mill AGC hydraulic cylinder piston, move together with piston, when hydraulic cylinder moves upward, because the action sensing device of spring 8 protection cylinder sleeve 6 moves upward, drive magnetic scale 5 and move upward, produce signal through magnetic head 4, pass through cable transmission; Sensor constantly is filled with nitrogen in the cylinder body in the continuous motion of production process, make the inside of displacement transducer form malleation.Nitrogen is entered in the sensor cylinder body, form protection, this structure prolongs the service life of displacement transducer effectively, reduces the advantages such as fault rate of displacement transducer, has guaranteed the milling train reliability service.
