Description
Technical field:
The utility model relates to weighing apparatus detection method and device, particularly mobile hydraulic pressure sensing detection device for truck scale.
Background technology:
The truck scale structure generally is made up of the pedestal of several uniform load sensors of the board-like scale pan, scale pan below, load sensor below, and the load sensor signal is exported to the computing that superposes of PLC processor, then shows its weight data by display.Set up the purpose of pedestal to be the flat benchmark of plurality of sensors water detection is made it on same surface level.Pedestal is divided into monoblock type or split type, monoblock type is that two row's load sensors in the holder of monoblock steel plate structure, or respectively there is " worker " word steel both sides, prop up a monolateral biographies sensor on " worker " word steel, split type is that single-sensor is placed on the single-point seat, all good level references in single-point seat school.
Truck scale can produce error after using a period of time, need detect it and proofread and correct, otherwise this error can be brought problems such as charge error, overload management, even influence traffic safety.Conventional detection has only counterweight weight relative method, promptly carries counterweight with automobile, moves counterweight again and is placed on the scale pan and contrasts; Or the alternative counterweight of truck directly detects.This method carrying effort, vehicle-mounted counterweight weight is too big, power consumption is big, and accuracy of detection is low simultaneously, and work efficiency is also low.
Tangshan City Kaiping District traffic branch office once disclosed a kind of " the quick useful test instrument of electronic vehicle weighing apparatus ", and had applied for patent in October, 2006.The technical scheme of this calibrating instrument is: place a lifting jack at the load sensor top, place a sensor jacking block on the lifting jack, head on a crossbeam on the jacking block, the barb of the longitudinal rod bottom that the crossbeam two ends are fixing hangs over the integrated footings lower surface, the lifting jack lifting of having an effect then, built-in display is read the numerical value of having an effect of lifting jack from the jacking block, compares with the original weighing apparatus display of truck scale reading, just can calculate error amount.
This method with the sensing data comparison, more much higher than counterweight relative method precision.But there is following problem in this technical scheme:
1, tested weighing apparatus must be integrated footings, and split type pedestal can't be tested;
2, this device once can only be tested the pressure transducer under place's scale pan, if repeatedly test, not only testing apparatus need be moved, installation exercise, influence work efficiency, and because scale pan integral body is continuous mass, test a place and certainly will bring other to locate the coupling effect of pressure transducer, influence measuring accuracy;
3, because must extending into pedestal from the scale pan two avris, longitudinal rod implements barb, thereby the crossbeam width has determined the maximum specification of weighing apparatus to be measured, though be drilled with round on the crossbeam, longitudinal rod can be selected hanging hole, but can only regulate inside extension, that is to say, regulate the little scale pan of width, can't detect the scale pan greater than the crossbeam width;
4, most importantly this scheme only is applicable to small-sized weighing apparatus, can't realize on big weighing apparatus.
Summary of the invention:
The purpose of this utility model is to overcome above-mentioned defective, and a kind of mobile hydraulic pressure sensing detection device for truck scale is provided.
