Description
Technical field
The utility model relates to a kind ofly can effectively examine and determine the bunker scale scale correcting apparatus of verification to bunker scale, belongs to weighing instrument and makes the field.
Background technology
Along with the continuous lifting of metallurgical automation degree, the bunker scale automatic, quick, metering of large bulk cargo is used widely.In order to ensure the weighing accuracy of bunker scale, regularly bunker scale is calibrated and be very important with standard weights.The calibration of bunker scale is that standard weights is loaded on the bunker scale sensor by bunker scale scale body, makes the demonstration weight of signal of sensor on the indicator gauge of weighing of bunker scale identical with the loading standard weights.Standard weights realizes with counterweight or other alternative weight in the routine work, but considerable bunker scale is owing to reasons such as structural design, installation site, space sizes in the production scene, often do not reach during calibration standard-required calibration weight minimum value and influence the calibration effect, influence the accuracy of bunker scale, can't satisfy the requirement of production technology development.
The utility model content
Purpose of design: avoid the weak point in the background technology, design and a kind ofly can effectively examine and determine the bunker scale scale correcting apparatus of verification to bunker scale.
Design proposal: the utility model is according to the principle of stack comparison formula force measuring machine, and the power value that lifting jack is produced passes to good standard transducer of prior demarcation and the on-the-spot sensor that is calibrated bunker scale simultaneously by mechanical framework.The weight that shows on the supporting weighing instrument of standard transducer is exactly the weight that sensor loaded that is calibrated bunker scale, comes the field calibration bunker scale with this, regulates the output of lifting jack, is equivalent to change the size of heap(ed) capacity.
(1) framework has enough rigidity, and when lifting jack loaded, framework can not produce obvious variation, and deformation requirements is less than 0.1.General grooved or the case type structures of adopting.The rigidity of framework is to guarantee standard transducer and be calibrated the key that sensor obtains identical power.The height of framework will be determined according to the height of standard transducer and lifting jack.
(2) lifting jack simultaneously the power output value stabilization to guarantee that stabilization time was greater than 15 seconds.Select spiral lifting jack (mechanical type lifting jack) for use.When several lifting jack are worked simultaneously, need evenly afterburning simultaneously.
(3) output sensitivity of several standard transducers needs unanimity, and adopts the resistance strain type sensor of composition error little (0.02%FS).
(4) supporting weighing instrument has the three-way sensor signal input channel at least, and the corresponding display window of weighing is arranged, and can monitor the output weight of different sensors simultaneously.
(5) annex and other increase by one and load annex between lifting jack and standard transducer.Load annex enough rigidity will be arranged.Upper and lower surfaces are arranged on the annex, and next face is to load pressure head with standard transducer to match; A last face is identical with lifting jack bottom external diameter.So both can make standard transducer obtain reliable loading performance, and can make things convenient for the correct contraposition of standard sensing and lifting jack again.
Technical scheme: a kind of bunker scale scale correcting apparatus, hopper is positioned on the support and touches mutually with standard transducer under being positioned at it, lifting jack is positioned at the standard transducer below and touches mutually with standard transducer, the hopper sensor is positioned at the lifting jack below and touches mutually with lifting jack, and the hopper sensor is positioned on the support base plate.
The utility model is compared with background technology, the utility model is a kind of calibration steps of simple and fast of non-counterweight, form by standard transducer and weighing instrument, whole operation is simple and convenient, the time and labour saving, hopper claims that the installation and removal of calibrating installation are all very convenient, can satisfy the requirement to the bunker scale calibration of production scene, production technology; Secondly, this apparatus structure is simple, economical and practical and easy to operate, precision is high.

Embodiment
Embodiment 1: with reference to accompanying drawing 1.A kind of bunker scale scale correcting apparatus, hopper 1 is positioned on the support 2 and touches mutually with standard transducer 3 under being positioned at it, lifting jack 4 is positioned at standard transducer 3 belows and touches mutually with standard transducer 3, hopper sensor 5 is positioned at lifting jack 4 belows and touches mutually with lifting jack 4, and hopper sensor 5 is positioned on the support base plate 6.Described support 2 is grooved or case type structures.Described very heavy item 4, standard transducer 3 and bunker scale sensor 5 threes' central axes.
(1) before the use, earlier that standard transducer 3 and supporting weighing instrument is fixed at the enterprising rower of force measuring machine (or counterweight).
(2) standard transducer 3 hopper weigh sensors 5 load plate above, lifting jack 4 is placed between the framework of standard transducer 3, adjusts the three position, makes very heavy 4, standard transducer 3 and bunker scale sensor 5 threes' central axes.
(3) by supporting weighing instrument, finely tune each lifting jack 4, make each point be subjected to some power and each point stress balance.
(4) operation bunker scale weighing instrument makes instrument be shown as zero.
(5) calibrate the weight that should add, calculate the weight that each point on average should add, show according to supporting weighing instrument, even regulation lifting jack 4 loads simultaneously.Supporting weighing instrument shows required weight, after stablizing, should calibrate the bunker scale weighing instrument as quickly as possible.
(6) after calibration was finished, supporting weighing instrument and the bunker scale weighing instrument value in each gear weight was compared in lifting jack 4 or loading, or unloading, calculates the accuracy of bunker scale.
What need understand is: though the foregoing description is to the mentality of designing of the present utility model detailed text description of contrasting; but these text descriptions; just the simple text of the utility model mentality of designing is described; rather than to the restriction of the utility model mentality of designing; any combination, increase or modification that does not exceed the utility model mentality of designing all falls in the protection domain of the present utility model.
