Description
Technical field
The utility model relates to a kind of induction type level detector, belongs to Instrument technology field.
Technical background
In the daily production in some field, some bulk cargos need by means of bunker, all roll-overs or supply the warehousing of quantity-produced feed to deposit, as bulk cement, grain etc.Turnover along with the warehousing material, or for producing use continuously, the storage capacity of material is in continuous variation in the storehouse, as produce the bulk cement feed storehouse of use continuously for concrete mixer, cement reserves in its storehouse constantly reduce the carrying out along with production, in order not influence ordinary production, need detect controlling level in the storehouse at any time, so that feed supplement in time.The method that detects controlling level in the storehouse has multiple, and wherein, heavy method is pedaled on ladder as the operator, and an edge ladder is climb, with hammer flattener knock bulkhead on one side, judge controlling level with knocking the sound that sends, so not only require great effort, and poor accuracy.Advanced method, as by means of the Weight type detector, it is to survey empty material level by the drop that the weight of instrument is fallen material surface in the storehouse, its advantage is laborsaving, and its weak point is that this instrument can not be indicated continuously, and measuring error is big, and as surveying cement, general error is about 300mm.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of induction type level detector, and this level detector can be indicated warehousing bulk cargo level, measuring accuracy height continuously.
It is as follows to solve the problems of the technologies described above the technical scheme that is adopted:

Above-mentioned induction type level detector, said gearing are windlass, and probing shell is hung the traction end at the wire rope of lifting drum, and indicating device is one to change the continuous indicating device that changes synchronously with material level.
Above-mentioned induction type level detector, it is characterized in that said and material level change the continuous indicating device that changes synchronously be one with the isometrical coaxial synchronous hoist barrel of lifting drum, the rope traction end of synchronous hoist barrel is hung an indication weight synchronously.
Above-mentioned induction type level detector, the said continuous indicating device that changes synchronously with the material level variation is a slide rheostat, its sliding end is a fork, fork is provided with vertical transmission chute, is provided with trundle in the chute, and a trundle and a nut are fixed, nut cooperates with a leading screw, leading screw and lifting drum are coaxial, and fork afterbody and windlass frame are hinged, and rheostat link and windlass frame are fixed.
It is a grating and the electrooptical device that place grating both sides coaxial with lifting drum that above-mentioned induction type level detector, said and material level change the continuous indicating device that changes synchronously.
Different performance index according to different model near switch, and according to the angle of repose of survey material, above-mentioned induction type level detector, two of said probe side by side and up and down arranged in dislocation on housing near switch, axis centre is apart from being adjustable between 40mm-120mm side by side for it, and dislocation is for adjustable between 20mm-160mm up and down.
Above-mentioned induction type level detector, the housing upper end of said probe is provided with lead and draws the storehouse in.
Induction type level detector provided by the utility model, its exploration head adopts capacitive approach switch, and the characteristic of this switch is, and when object during near the induction range of switch, switch is connected voluntarily.This induction type level detector designs according to this principle of work near switch.Model such as the TC-18-10 near the switch that are adopted, its induction range is that 1-20mm is adjustable.This kind switch is to metal, plastics, grain, glass, cement, sand, stone, water, the equal reliable operation of wet goods material.This induction type level detector is specially adapted to the measurement to material levels such as warehousing bulk cargo such as cement, sand, stone, grain height.Its course of work is such: two switches installing when interlacing up and down are apart from the material surface when too high, two switches are open circuit, at this moment, windlass work, probe is descended, when dropping to when connecing the inductive switching scope less than the head of exploring following with the distance on material surface, connect voluntarily near switch down, at this moment, two are in a connection near switch, an off-state, in this state, windlass quits work, in this working routine, windlass makes the following distance near switch and tested material surface of probe remain in the induction range of this switch all the time, promptly in the scope of 1-20mm.When giving the bunker material loading, when the material surface be elevated to probe go up induction range near switch the time, go up and connect voluntarily near switch, at this moment, all be in on-state near switch about the probe, in this state, windlass oppositely starts, probe is risen, when the last distance near switch and material surface that rises to probe exceeds its induction range, upward disconnect voluntarily near switch, windlass quits work, and the synchronously continuous indicating device that links to each other with its lifting drum axle can change synchronous height of indicating level of filler material in the storehouse continuously with the lifting of probe in the storehouse.Also the change in location of probe lifting can be converted into electric signal, switch or Long-distance Control between automatic storehouse so that realize.
