Description
[technical field]
The utility model relates to the manufacturing field of electronic scale, the large-scale fixed electronic scale that particularly a kind of non-counterweight device capable of using is examined and determine.
[background technology]
Fixed electronic scale is technological in the world at present the most ripe Weighing utensil; Belong to the measurement instrument that has a large capacity and a wide range; Be widely used in the metering of various load-carrying vehicles of metallurgy, chemical industry, railway, harbour and industrial and mining enterprises and goods; And be used for the weigh technology controlling and process of flow process of trade settlement, production run, be the desirable metering outfit that the Weighing modernization level improves in enterprise.The principle of work of fixed electronic scale is that weigh thing or truck of quilt placed on the weighing platform, under action of gravity, weighing platform with weight transfer to waving supporting (steel ball, pressure head etc.); Make Weighing sensor elastomer produce deformation; Be attached at the foil gauge bridge circuit out of trim on the elastic body, output and the directly proportional electric signal of gravimetric value are amplified signal through linear amplifier; Convert digital signal into through A/D again, by the microprocessor of instrument signal is handled the back then and directly show the weight number.
Fixed electronic scale must be examined and determine before actual coming into operation, and confirms its class of accuracy, in addition; Large-scale weighing machine is in use for some time or after changing device; Also to examine and determine once more, confirm its class of accuracy, make it to satisfy accuracy requirement so that do corresponding adjustment.The standard that the fixed electronic scale of existing calibrating is used mainly contains three kinds; Standard No. is to have spelt out the following three kinds of calibratings that allow to adopt in the national standard (this standard adopts international recommendation OIML R76 " non-automatic weighing apparatus " (2006E)) of the fixed electronic scale of GB7723-2008 to use standard: the one, and counterweight specifically is meant standard test weight or standard quality; The 2nd, auxiliary calibrating installation is meant that specifically weighing apparatus is equipped with auxiliary calibrating installation or independently auxiliary calibrating installation; The 3rd, calibrating substitutes with standard test weight, specifically is meant part of standards counterweight and other any fixed load alternate standard counterweights.
Yet there is following shortcoming in the calibration method that adopts standard test weight or standard test weight and substitute to examine and determine fixed electronic scale:
1, calibration operation amount is huge, efficient is extremely low.Examine and determine that a fixed electronic scale of qualified 100t need be moved counterweight altogether and substitute reaches 932t, if defectively just need adjustment, must examine and determine again after the adjustment, calibrating must be carried counterweight once more again, and its carrying counterweight or substitute reach more than the kiloton;
2, the security extreme difference of a large amount of counterweights of carrying or substitute.Because the loading floor area limited (as 100 tons, footprint also has only about 54 squares) of electronic scale, counterweight or the substitute that on limited area, stack 100 tons are very difficult, when loading and unloading counterweight or substitute, are danger closes;
3, substitute is difficult to seek.The user who is not every large-scale fixed electronic scale can both provide suitable substitute; As be installed in the other standard scale of highway and just be difficult to find suitable substitute, railway, harbour, there are users such as venom, gas chemical enterprise, textile mills, colliery also to be difficult to the substitute that provides suitable;
4, standard test weight is difficult to transportation.Examine and determine 100 tons of electronic scales, will transport 50 tons of standard test weights at least; Examine and determine 150 tons of electronic scales, will transport 75 tons of standard test weights at least.Also can only about 15 tons and transport counterweight at present at home, particularly there are unsafe bridge limit for tonnage, road limit for tonnage, landform limit for tonnage in the area, mountain area, is installed in the gully (like mine) or the like and will limits the counterweight freight volume No. one time;
5, cost is high.Transportation and carry so many standard test weight or substitute needs multi-section weigh bridge test car and crane, and calibrating needs several days time (examine the general need of 100 tons of truck scales 7 working days and multi agent cooperation and could accomplish calibration operation.
Therefore; Open day is on Dec 08th, 2010; Publication number is the Chinese invention patent of 101907484A; Patent " system and the self-location loading-unloading measuring device thereof of calibrating large-scale weighing machine " by name; A kind of weighing instrument verification device of non-counterweight type is disclosed, concrete technical scheme be self-location loading-unloading measuring device comprise one can be used for alternate standard counterweight or standard test weight substitute the weighing platform table top is added the high precision Load Meter that the upper end of self-align loading and unloading body and the said loading and unloading body of a next-door neighbour of unloading is provided with, the accuracy of said high precision Load Meter is at least 3 times of accuracy of said weighing apparatus; Should technology the problems referred to above have been solved simultaneously.The utility model will be that self-location loading-unloading measuring device is designed a kind of large-scale fixed electronic scale that cooperates this device to use according to the weighing instrument verification device of this non-counterweight type.
[utility model content]
The technical matters that the utility model will solve is to provide a kind of large-scale fixed electronic scale that cooperates self-location loading-unloading measuring device to use, and its calibrating efficient is high, the calibrating security is big, and it is low to examine and determine cost simultaneously.
The utility model is achieved in that
A kind of large-scale fixed electronic scale; Comprise a weighing apparatus table top; Said weighing apparatus table top is provided with at least two weighing apparatus and carries sensor, and is connected with ground through these at least two weighing apparatus carrying sensors, and said at least two weighing apparatus carry sensor and all are connected on the sensor display instrument; Said weighing apparatus table top is equipped with at least two platform holes, is equipped with the web member that is embedded on the ground under each said hole.
Further, each said hole is respectively adjacent to corresponding weighing apparatus and carries the sensor setting.
Further, the said web member that is embedded on the ground is the web member that can bear 0～50 ton pulling force.
The utility model cooperates a kind of self-location loading-unloading measuring device to use, and has the following advantages:
1, calibration operation amount is little, safe.Because the utility model can utilize self-location loading-unloading measuring device to add unloaded automatically, need not to move hundreds of ton counterweight or substitute the utility model is examined and determine, the calibration operation amount is little, safe.
2, calibrating efficient is high.The utility model a kind of self-location loading-unloading measuring device capable of using detects self; Need not the required a large amount of standard test weights of transportation calibrating and seek substitute; Just can examine and determine the large-scale fixed electronic scale of 100 tons or 200 tons on half working day, work efficiency is high.
3, the required cost of calibrating is low.When the utility model is examined and determine, only need a jubilee wagon once just can self-location loading-unloading measuring device be transported to the destination, as long as just can accomplish calibrating half working day, traffic expense and labour cost expenditure can reduce greatly.
