As shown in Figures 1 to 9,
A kind of large-tonnage substitution counterweight calibration calibrating installation, includes scale body 1 and substitution counterweight 7, the upper surface of scale body 1 is set
Leading truck 2 compatible with substitution counterweight 7 is set, the lower section of scale body 1 is provided with weight sensor 3, and weight sensor 3 is set to institute
It states the quadrangle of scale body 1 and the center on upper and lower side, weight sensor 3 is controlled to a power supply through conducting wire, weight sensor 3 is fixed
In on bottom plate 4, sensor transition piece 31 is set between 1 scale body of weight sensor 3 and the scale body；The following four corners of scale body 1 point
It is not provided with limiting device 5；Counterweight 7 is substituted by being made after injecting discarded iron bearing hydraulic in steel scrap packet.
This calibration calibrating installation, weight sensor 3 are set to the quadrangle of scale body 1, and in the upper and lower side of scale body 1
A weight sensor 3 is also respectively arranged in the heart, and six weight sensors 3 are in distributed rectangular, is sensed using the weight of six point types distribution
Device 3 is conducive to the raising for weighing accuracy.
Used weight sensor 3, range 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 in after processing on display screen or main controller.
In embodiment, the number of leading truck 2 is 4, and 4 leading trucks 2 are uniformly distributed on periphery, leading truck 2 it is upper
Surface is the inclined-plane 2a that outside is higher than inside.
The setting of leading truck 2, greatly facilitates the placement and positioning of substitution counterweight 7, and the inclined-plane 2a of upper surface is being substituted
In 7 decentralization process of counterweight, guiding role can be functioned well as, to keep being put into for substitution counterweight 7 more smooth, can be shortened
It is entire to weigh the time.
In embodiment, limiting device 5 includes limit divider 51 and limit liner plate 52, and the upper end of limit divider 51 is formed with
Supporting plane, limit liner plate 52 are fixed on the bottom plate 4, and limit divider 51 is fixed with 52 phase of limit liner plate.
Limiting device 5, which is arranged, can effectively avoid causing the damage of weight sensor 3 because weighed object is overweight；When
When weighed object is overweight, with the decline of scale body 1, the supporting plane of the upper end of the lower surface and limit divider 51 of scale body 1
It offsets, since 5 scale body 1 of limiting device no longer declines, thus the weight sensor 3 of 1 lower section of effective protection scale body.
In order to protect weight sensor 3, calibrating installation is being demarcated when not used, upper cushion block is padded below scale body 1, in this way can
Avoid 3 long-time stress of weight sensor and caused by damage and the decline of service life.
In embodiment, scale body 1 is spliced to form by unit scale body 11, by connection loading plate 12 and even between unit scale body 11
Installation part 13 is connect to be connected.
In embodiment, the two sides of connection loading plate 12 are respectively arranged with limited block 12a.

In embodiment, penetration pipe 11g is preset in unit scale body 11.Setting penetration pipe 11g can significantly facilitate each conduction
The arrangement of line, signal wire keeps wiring more neat；Meanwhile also can how each conductor wire, signal wire play a certain protective role.
In embodiment, hose 6 is cased with outside conducting wire.The setting of hose 6 is also for playing a protective role.
In embodiment, bottom plate 4 is fixed on ground by fot screw 41.
Wherein, panel 11a uses yield strength for 235Mpa, and maximum stress in bend is the steel plate Q235A of 63Mpa, table top
The weakness that local strength is poor without aperture, caused by being avoided that because of aperture, structurally internal stress is concentrated；Welding uses carbon dioxide gas everywhere
Body protection weldering, welding interior stress are few, it is ensured that deflection is few after 1 ag(e)ing process of scale body.
The metering performance for the measuring equipment that works online depends on the maintenance of its magnitude tracing chain and equipment；Magnitude tracing is logical
A continual relatively chain with regulation uncertainty is crossed, measurement result or the value of measurement standard and defined ginseng are enable
Examine the characteristic that standard (usually national measurement benchmark or international metering benchmark) connects.
The magnitude tracing chain for 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 substitution counterweight 7.
It substitutes counterweight 7 and calibrates magnitude tracing chain: substitution calibration of weight device → 3 → force measuring machine of weighing sensor → country's mark
Quasi- load cell.
This substitution counterweight calibration calibrating installation is installed on production scene, " can be seized every opportunity " in process of production to substitution weight
Code and online metering facility are calibrated, and can be greatly shortened the duty cycle, be can be improved production efficiency.When check weighing, substitution
Counterweight 7 is put on scale body 1 by crane handling, and the bearing point position of scale body 1 is overlapped with 3 supporting-point of weighing sensor.Loosen crane
Suspension hook (cannot disengage, to guarantee safety), and substitution 7 all-mass seat of counterweight enters scale body 1, after stablizing, weighing instrument show value, i.e.,
Substitute counterweight 7.
This calibration calibrating installation is suitable for smelter by 7 alternate standard counterweight of substitution counterweight or the object of known weight
Or the on-line calibration calibration of the large-tonnage wide range Weighing facility in other large enterprises.Its calibration can be completed disposably,
It avoids the object using standard test weight or known weight and is marked by the way of additionally assisting other components to be gradually superimposed
Fixed work, substantially reduces calibration degree, has saved the nominal time and (can be completed within 10-20 minutes), can effectively improve production
Efficiency.
Highly preferred embodiment of the present invention has illustrated, and the various change or remodeling made by those skilled in the art will not all take off
From the scope of the present invention.
