Description
Technical field
The utility model relates to weighing equipment, and the integrated large-scale weighing rail of the object of wheel or rolling is arranged in particular for weighing.
Background technology
The weighing rail is often adopted in the weighing of existing oversize vehicle and train, during vehicle process weighing rail, by the induction of weighing rail, and obtains measured value.This measurement generally is to convert gravity to electric weight output by sensor, and sensor generally is made up of sensitive element, conversion element, circuit, wherein the sensitive element of rheostatic type and resistance strain type sensor is an elastic body, and conversion element is respectively potentiometer and resistance strain gage.
Normally used weighing rail has following two kinds: wherein a kind of weighing rail is by elastic body, foil gauge, circuit is formed, its elastic body is to use proprietary material to make, be generally converted steel, as 40 chromium nickel molybdenums etc., when the long more processing technology difficulty of its length big more, manufacturing cost is high more, so generally have only 800 millimeters long now, when being installed in it on railway line, this length makes it to join with common rail, because the single-ended joint length of common rail just needs 400 millimeters long, thereby this weighing rail all is that disconnected rail is connected the both dangerous measuring accuracy (the vibrations meeting of joint directly influences measuring accuracy) that also influences with rail on railway line.
Another kind of weighing rail is after boring on the common rail, compression leg formula sensor is filled in formed the weighing rail in the hole.How this weighing rail no matter wringing fit between sensor and the rail, between sensor and rail, all have the gap, the power transmission interface is all arranged, have mechanics (or electricity) glitch that is difficult to eliminate, and be in-situ processing, be difficult to accurate demarcation, metering is inaccurate, so can't objectively respond the weight of institute's survey vehicle, vehicle repeatedly will make the gap between them increase through the vibrations that produce, and aggravated measuring error, so serviceable life is short, error is big.
Summary of the invention
The utility model purpose is to overcome above-mentioned weak point of the prior art, and a kind of safety is provided, the integrated large-scale weighing rail that measuring accuracy is high.
The integrated large-scale weighing rail of the technical scheme that the utility model adopted, comprise rail, foil gauge, circuit, even number bar rail distributes side by side and forms the weighing rail, its structural feature is that the length of rail is the 1500-25000 millimeter, foil gauge is fixed on the web of the rail surface of rail, is fixed with two above foil gauges on the every rail.
Rail both had been the elastic body of weighing rail, like this because the length of rail is long, fixedly the time, available web member connects, thereby has overcome the shortcoming that original disconnected rail connects, and vehicle is increased through the security of rail, shake for a short time, vibrations are also reduced the measuring accuracy height to the influence of sensor; Simultaneously, because of sensor be installed in web of the rail surface, gap when not existing the hole to install and the mechanics that is difficult to eliminate (or electricity) glitch that friction tight prestress caused can reflect the weight of institute's survey vehicle comparatively objectively.
The purpose of this utility model can also realize by following approach.
Rail is the rail that common material is made, and uses the elastic body of existing common rail as the weighing rail, can reduce cost, and generally selects for use: light rail 24,38; Heavy rail 43,50,60,70; Crane rail 70,80,100,120 kg/every meter.
The direct hot setting of foil gauge is on the web of the rail of rail.Therefore it is to make in factory's integral body, and foil gauge and rail are integral, and do not have the gap between the two, before metering and in the metering, foil gauge all is in free state, no extra weight on the foil gauge, also do not have the error that causes because of the gap, metering is reliable, long service life.In addition it also has an outstanding advantage, and that is exactly that it can carry out accurate verification with standard test weight in factory, and this has more increased its degree of accuracy.
Per two one group of a plurality of foil gauge, each spacing of organizing two foil gauges is identical, and the group spacing is identical, and the group spacing is identical with the wheel spacing of required measured vehicle.So-called group of spacing is meant the distance of the foil gauge of same position between two adjacent groups, is the distance between first foil gauge of first group first foil gauge and second group as: the group spacing between first group and second group.Be fixed with 1-4 group foil gauge on the general one steel rail.
Can further it be specially: the spacing of every group of two foil gauges is the 300--1200 millimeter.
The utility model better choice is that rail length is the 5000-16000 millimeter.
Because the length long enough of weighing rail, wheel all has damping to isolate target phase before and after entering, withdraw from each sensor like this, and the shock absorbing performance is good, the precision height, and the rail connecting plate of available routine--fish platee connects, and is easy to install simple.
The utility model can be made up of two weighing rails side by side, or joins weighing rail composition side by side in twos by four.By that analogy, can form more large-scale scale by more even number bar weighing rail.
Advantage of the present utility model is that fixedly the time, available web member connects because the length of weighing rail is long, thereby overcome the shortcoming that disconnected rail connects, vehicle is increased through the security of weighing rail, vehicle by the time vibrations little, reduce to shake influence, the measuring accuracy height to foil gauge.It is to make in factory's integral body, the simultaneously direct hot setting of a plurality of foil gauges is on the web of the rail, be integral with rail, there are not the gap in foil gauge and rail between the two, before metering and in the metering, foil gauge all is in free state, there is not the error that causes because of the gap in no extra weight on the foil gauge yet, and metering is reliable, it can carry out accurate verification with standard test weight in factory, this has more increased its degree of accuracy.
