Description
Technical field
The utility model belongs to bunker scale calibration equipment, and especially a kind of realization bunker scale is without counterweight calibration equipment.
Background technique
Bunker scale is the weighing electronic scale for measuring material in hopper weight.The calibration process of bunker scale is by standard weight
The object of amount is loaded on bunker scale sensor by bunker scale scale body, makes the output signal of bunker scale sensor on weighing table
Display weight compare with loaded standard weights.
Counterweight is copied when bunker scale verifies every time mechanically to verify burden balance.Large labor intensity, checking precision be not high.Due to
It is verified using 20 kilograms of counterweights, and verifies the range that counterweight only has 1 ton, be unable to reach full scale verification, and in checking procedure
It is cumbersome and time consuming, technique requirement cannot be reached.
Utility model content
The purpose of this utility model is to provide a kind of realization bunker scales without counterweight calibration equipment, structurally reasonable, can be with
Simplify school scale process, reduce labor intensity, improve working efficiency, improves checking precision.
Purpose of the utility model is realized as follows: a kind of realization bunker scale is included in hopper without counterweight calibration equipment
Below be arranged and be evenly distributed with symmetrical hopper sensor and constitute bunker scale, symmetrical door shape school is respectively set in the two sides of hopper
Frame is tested, is respectively and fixedly connected with symmetrical horizontal boom load plate on the bucket wall of hopper two sides, and load plate is from door shape
It is pierced by verification framework, is successively coupled jack, cushion block from bottom to top in the load plate in door shape verification framework
And pressure gauge, the top surface of pressure gauge are matched with door shape verification framework crossbeam, wherein jack, pressure gauge and symmetrical hopper pass
The central axis of sensor three coincides.
The utility model is a set of by being formed using hydraulic loading mechanism, High-precision standard sensor, high-precision display instrument
Calibration equipment substitutes traditional counterweight verification.The composition of calibrating installation has frame, jack, standard TY-LB-C-3BJ pressure gauge
And cushion block.
1) frame: having enough rigidity, and when jack load, frame cannot generate apparent variation, deformation requirements
Less than 0.1mm, and use groove profile or case type structures.The rigidity of frame is to guarantee that standard transducer is obtained with sensor is calibrated
The key of identical power.The height of frame will be determined according to the height of standard transducer and very heavy item.
2) jack: while output force value stability will guarantee, stablize the time greater than 15 seconds.Select screw jack
(mechanical jack).When several jack work at the same time, uniformly reinforcing is needed simultaneously.
3) standard TY-LB-C-3BJ pressure gauge: digital weighing system is used, stress can be directly displayed by digital instrument
Value.
4) cushion block and other: increase a load cushion block between jack and standard transducer.Load cushion block will have foot
Enough rigidity.There are upper and lower surfaces on cushion block, next face is matched with standard TY-LB-C-3BJ pressure gauge load pressure head.On
One face is identical with very heavy top/bottom part outer diameter.Standard transducer can have not only been set to obtain reliable loading performance in this way, but also can be convenient
The correct contraposition of standard sensing and jack.
Live bunker scale sensor load plate need to be suitably increased in size, thickness, and be welded with three in two sides when designing processing
Angle gusset, more strength.Simultaneously it is also contemplated that the positioning device of standard transducer and bunker scale sensor.Frame, jack, mark
Quasi- sensor should be according to the range Uniting of live bunker scale, processing.It is thorough to consider when transformation, guarantees safety.According to existing
Field measures batch weigher actual size, needs 100(10#) 48 meters of channel steel, 300(30#) 120 meters of channel steel.The verification of preparing ingredients scale
24 small mines of device claim 48 calibration equipments and are installed on burden balance frame.
Before use, first BJ pressure gauge is demarcated with counterweight；BJ pressure gauge hopper scale sensor load plate
Above, jack is placed between BJ pressure gauge and frame, adjusts three position, passes very heavy item, BJ pressure gauge and bunker scale
The central axis of sensor three is overlapped；It is shown by BJ pressure gauge, finely tunes each jack, make each point by some power, and each point
Stress balance；Verified bunker scale weighing instrument is shown as being also displayed as zero after zero, BJ pressure gauge is reset after resetting instrument；
The weight that should add is calibrated, the weight that each point should averagely add is calculated, is shown according to BJ pressure gauge, while even regulation jack adds
It carries, BJ pressure gauge shows required weight, after stablizing, the show value of display instrument is inquired by intercom, what is be just exceedingly fast passes through meter
Calculate calibration bunker scale weighing instrument；After the completion of calibration, jack or load, or unloading, compare mating weighing instrument and bunker scale
Weighing instrument calculates the accuracy of bunker scale in the value of each gear weight.
The utility model has the advantages that
This practical patent is easy to operate compared with relatively traditional counterweight method of calibration, greatly improves labor efficiency, reduces
Service personnel's labor intensity, checking precision and reliability also have big raising simultaneously.
The scope of application and application prospect:
It is lower that this practical patent is intended to solution hopper counterweight school scale complicated for operation, school scale large labor intensity, school scale precision
The problems such as, in industry there are very high utility value and promotion prospect.
The utility model is structurally reasonable, simplifies school scale process, reduces labor intensity, improve work efficiency, and improves
Checking precision.
