Description
Technical field
The utility model relates to material-level detecting device, is specifically related to a kind of concrete silo material-level detecting device.
Background technology
At concrete mixing plant, concrete silo as storage a concrete tun, for concrete tank provides concrete.In order to obtain concrete consumption every day, must the concrete material level in feed bin be detected, but to comprise radar material meter, ultrasonic material level detection unit etc. multiple for the instrument of the detection bin-level used at present.But in actual production, because severe production environment easily causes the instrument damage of these material-level measure, these instruments normally cannot be used, and then Measurement accuracy can not be carried out to concrete material level.Once after these instruments break down, personnel just must be arranged to climb up concrete silo, along from feed bin Cang Ding to the cat ladder of downward-extension, beat successively with iron hammer, detect material level with hammering method.This not only consumes a large amount of time, have impact on the normal operation of work, reduces work efficiency, and simultaneously testing staff climbs up feed bin and detects and also have certain danger.
Utility model content
For above-mentioned the deficiencies in the prior art, technical problem to be solved in the utility model is: how to provide one not fragile, easy to use, improves detection efficiency, reduces and detects dangerous concrete silo material-level detecting device.
In order to solve the problems of the technologies described above, the utility model have employed following technical scheme:
A kind of concrete silo material-level detecting device, it is characterized in that: comprise and be fixedly connected on feed bin top and be oppositely arranged two bracing frames I, reel is provided with and the two ends of reel are rotatably assorted with two support frames as described above I respectively between two support frames as described above I, described feed bin top is also provided with the servomotor for driving described spool turns, described reel is wound with serving, on described serving, mark has length scale line along its length, one end of described serving is fixedly connected on described reel, the other end of described serving extend in feed bin through described feed bin top, described serving is connected with balancing weight away from one end of described reel, the bottom surface of described balancing weight is provided with for detecting concrete closed type microswitch, two terminal series-shunt of described closed type microswitch are on the current supply circuit of described servomotor.
In the utility model, when detecting concrete amount, first concrete material level original in feed bin is detected.Start servomotor operation spool turns outwards release serving, serving under the effect of balancing weight to decline.Balancing weight touches concrete in its bottom surface when declining, the closed type microswitch be positioned on balancing weight bottom surface is subject to exciting rear circuit to disconnect, and then the current supply circuit of servomotor is also disconnected simultaneously, servomotor quits work, now read the length scale value on serving, and restart servomotor withdrawal serving.After concrete uses, when needing to calculate concrete consumption, start again servomotor and release serving, the current supply circuit of servomotor is disconnected after the closed type microswitch on balancing weight touches concrete, read the length scale value on serving again, and compare with the length scale value obtained before, just can obtain concrete material level falling head in feed bin, then calculate concrete use amount according to cubature formula.Use simple and fast, only measure before concrete uses and after using and just can calculate concrete use amount, improve detection efficiency, equipment is not fragile simultaneously, safeguard simple, no longer need personnel to climb feed bin, the danger brought when reducing detection in addition.
As optimization, the side that described feed bin top is positioned at described reel is also provided with serving guide piece, the projection of described serving guide piece in the vertical direction is positioned at outside the projection of described reel in the vertical direction, described serving guide piece comprises two and is oppositely arranged and the bracing frame II be fixedly connected with described feed bin top, the coupling shaft paralleled with described spool axis is provided with between two support frames as described above II, the two ends of described coupling shaft are fixedly connected with two support frames as described above II respectively, described coupling shaft is set with fixed pulley and fixed pulley and described coupling shaft are rotatably assorted, described serving extend in described feed bin after walking around described fixed pulley away from one end of described reel.The position be wound around on reel due to serving is different, reel is when outwards releasing serving, and serving the circumference of relative reel can have certain displacement, will cause the swing of balancing weight like this, the closed type microswitch on balancing weight may be caused to touch concrete, make measurement inaccurate.After adding serving guide piece, serving is released from reel is upper outside, just enter in feed bin after walking around fixed pulley, and fixed pulley is irremovable, for serving provides a fixing fulcrum, balancing weight is declined more stable, better make closed type microswitch touch concrete and then close servomotor, improve accuracy in detection.
As optimization, described balancing weight is round table-like, and the center of balancing weight end face is fixedly connected with link, and described serving is fixedly connected with away from one end of described reel and mounts with described link the hook be connected.Round table-like balancing weight size is big top and small bottom, makes the center of gravity of whole balancing weight be reduced like this, improves the stability that balancing weight declines.
As optimization, the quantity of described closed type microswitch is on the multiple and irregular bottom surface being arranged on described balancing weight.Because concrete self has some strength, the material level in feed bin can not be in horizontality always, and arranging multiple closed type microswitch increases and concrete contact point, controls more accurately to servomotor, improves the accuracy detected.
In sum, the beneficial effects of the utility model are: the utility model structure is simple, easy to use, only measure before concrete uses and after using and just can calculate concrete use amount, improve detection efficiency, equipment is not fragile simultaneously, safeguards simple, personnel are no longer needed to climb feed bin, the danger brought when reducing detection in addition.
