Part 13, leading truck 2, inclined-plane 2a, weight sensor 3, sensor transition piece 31, base plate 4, fot screw 41, stopping means 5, limit
Position divider 51, spacing liner plate 52, flexible pipe 6, replacement counterweight 7.
As shown in Figures 1 to 9,
A kind of large-tonnage substitutes counterweight and demarcates calibrating installation, includes scale body 1 and substitutes counterweight 7, and the upper surface of scale body 1 sets
Putting the leading truck 2 suitable with substituting counterweight 7, the lower section of scale body 1 is provided with weight sensor 3, and weight sensor 3 is arranged at institute
Stating corner and the center on upper and lower limit of scale body 1, weight sensor 3 is connected with power supply through wire, and weight sensor 3 is fixed
On base plate 4, between weight sensor 3 and described scale body 1, sensor transition piece 31 is set；The four corners below of scale body 1 sets respectively
It is equipped with stopping means 5；Substitute counterweight 7 to be prepared by after injecting discarded iron bearing hydraulic in steel scrap bag.
This demarcation calibrating installation, its weight sensor 3 is arranged at the corner of scale body 1, and in the upper and lower limit of scale body 1
The heart respectively arranges a weight sensor 3, six rectangular distributions of weight sensor 3, uses the weight sensing of six point type distributions
Device 3, is conducive to weighing the raising of accuracy.
The weight sensor 3 used, its range is 0-200t；Accuracy: 0.03%F.S, sensitivity: 2.0 ± 0.2%
mV/V；Overload capacity: 200%F.S.
The weighed data of weight sensor 3, are shown on display screen or main control computer after treatment.
In embodiment, the number of leading truck 2 is 4, and 4 leading trucks 2 are uniformly distributed on periphery, leading truck 2 upper
Surface is the outside inclined-plane 2a higher than inner side.
The setting of leading truck 2, greatly facilitates and substitutes the placement of counterweight 7 and location, and the inclined-plane 2a of upper surface, substituting
In counterweight 7 decentralization process, it is possible to function well as guide effect, so that it is the most smooth to substitute putting into of counterweight 7, it is possible to shorten
The whole weighing time.
In embodiment, stopping means 5 includes spacing divider 51 and spacing liner plate 52, and the upper end of spacing divider 51 is formed
Supporting plane, spacing liner plate 52 is fixed on described base plate 4, and spacing divider 51 fixes with described spacing liner plate 52.
Arrange stopping means 5 to be prevented effectively from and cause the damage of weight sensor 3 because weighed object is overweight；When
When weighed object is overweight, along with the supporting plane of the upper end of the decline of scale body 1, the lower surface of scale body 1 and spacing divider 51
Offset, owing to stopping means 5 scale body 1 no longer declines, thus effectively protect the weight sensor 3 below scale body 1.
In order to protect weight sensor 3, demarcating the calibrating installation not used time, below scale body 1, cushion block on pad, so can
The damage avoiding the long-time stress of weight sensor 3 and cause and the decline in service life.
In embodiment, scale body 1 is spliced to form by unit scale body 11, by connecting loading plate 12 and connecting between unit scale body 11
Connect installed part 13 to be connected.
In embodiment, the both sides connecting loading plate 12 are respectively arranged with limited block 12a.
In embodiment, unit scale body 11 by panel 11a, horizontal girder plate 11b, horizontal girder apply plate 11c, perpendicular girder plate 11d with
And perpendicular girder applies plate 11e and is welded, unit scale body 11 is in hollow structure.
In embodiment, in unit scale body 11, it is additionally provided with reinforcing plate 11f.
In embodiment, in unit scale body 11, it is preset with penetration pipe 11g.Penetration pipe 11g is set and can significantly facilitate each conduction
Line, the layout of holding wire, make wiring the most neat；Meanwhile, also how each conductor wire, holding wire certain protective effect can be played.
In embodiment, outside wire, it is cased with flexible pipe 6.The setting of flexible pipe 6 is also for playing a protective role.
In embodiment, base plate 4 is fixed on ground by fot screw 41.
Wherein, panel 11a uses yield strength to be 235Mpa, and maximum stress in bend is the steel plate Q235A of 63Mpa, table top
Without perforate, it is avoided that because perforate causes the weakness that local strength is poor, structurally internal stress is concentrated；Welding everywhere uses carbon dioxide gas
Body protection weldering, welding interior stress is few, it is ensured that after scale body 1 ag(e)ing process, deflection is few.
The metering performance of the measuring equipment that works online, depends on the maintenance of its magnitude tracing chain and equipment；Magnitude tracing is logical
Cross one there is the continual of regulation uncertainty to compare chain, enable value and the ginseng of regulation of measurement result or measurement standard
Examine the characteristic that standard (typically national measurement benchmark or international metering benchmark) connects.
The magnitude tracing chain of the measuring equipment that works online: the measuring equipment → standard substitution that works online → substitute calibration
Device → standard test weight or standard weights are in kind；Here standard substitution is to substitute counterweight 7.
Substitute counterweight 7 and calibrate magnitude tracing chain: substitute calibration of weight device → LOAD CELLS 3 → force measuring machine → country's mark
Quasi-force cell.
This replacement counterweight is demarcated calibrating installation and is installed on production scene, can " seize every opportunity " in process of production to substituting weight
Code and online metering facility are calibrated, and can be greatly shortened the working cycle, it is possible to increase production efficiency.During check weighing, substitute
Counterweight 7, by crane handling, is put on scale body 1, and the bearing point position of scale body 1 overlaps with LOAD CELLS 3 supporting-point.Loosen crane
Suspension hook (can not disengage, to ensure safety), substitutes counterweight 7 all-mass seat and enters scale body 1, after stablizing, and weighing instrument show value, i.e.
Substitute counterweight 7.
This demarcation calibrating installation, by substituting counterweight 7 alternate standard counterweight or the object of known weight, it is adaptable to smelter
Or the on-line calibration demarcation of the large-tonnage wide range Weighing facility in other large enterprise.Its demarcation can disposably complete,
Avoid using standard test weight or the object of known weight and the extra mode assisting other component to carry out progressively superposition to mark
Fixed work, substantially reduces demarcation degree, has saved the nominal time (within 10-20 minute, can complete), it is possible to be effectively improved production
Efficiency.
Most preferred embodiment of the present utility model illustrates, those skilled in the art the various changes made or remodeling are the most not
Scope of the present utility model can be departed from.
