Description
Technical field
The utility model relates to the precision measurement field, particularly a kind of on-line proving measurement mechanism for the static car load weighing system of rolling stock.
Background technology
In static whole vehicle weighing system, the demarcation of weighing system is the key link before the car load experiment of weighing.At present, weighing system caliberating device commonly used has two kinds, and a kind of is to adopt the standard test weight loaded weight, Weighing module contrast and match by counterweight indicating value and weighing system, realize the demarcation of Weighing module, and this mode is because counterweight weight is discontinuous load, therefore, stated accuracy is low.The second is to adopt the proving ring rigidity to pressing the mode that loads, although load has realized continuous loading, the temporary impact when stiffener loads, can cause the decline in Weighing module measuring accuracy and life-span, and increase the time of calibration measurements, and efficiency is lower.
The utility model content
The purpose of this utility model is to provide a kind of weighing rolling stock system on-line proving device, can load continuously, quick, efficient, realizes the high-precision calibrating to weighing system.
In order to achieve the above object, the technical solution of the utility model is: a kind of structure of weighing rolling stock system on-line proving device comprises weighing system, demarcates frame, guide pole, flexible member and standard LOAD CELLS.Adopt the mode of relative measurement, take the standard LOAD CELLS as benchmark, demarcate continuously the Weighing module in weighing system.
In described caliberating device, flexible member, standard LOAD CELLS and guide pole are connected in series successively and are placed on to be demarcated in frame, wherein the flexible member two ends are connected with the standard LOAD CELLS with the demarcation frame respectively, with the impact of buffering loaded load to the standard LOAD CELLS, improve stated accuracy, guide pole is connected with weighing system with the standard LOAD CELLS respectively, to transmit the loaded load of timing signal weighing system.
In described weighing system, comprise continuous jacking gear, Weighing module and frame, wherein Weighing module is connected with the guide pole of caliberating device, and jacking gear loads for load, and frame is used for the fixedly demarcation frame of caliberating device.
Described on-line proving device, utilize jacking gear in weighing system to load continuously, make Weighing module and standard LOAD CELLS measure respectively the continuous load data, and will be separately measuring-signal pass to computing machine and process, by the mode of least square method and multiple spot curve, realize the high-precision calibrating of Weighing module.
The utility model compared with prior art, has the following advantages: caliberating device is simple and compact for structure, uses quickness and high efficiency, owing to having increased flexible member, has improved precision and the efficiency of calibration measurements, is specially adapted to the on-line proving of weighing system.

Embodiment
Below in conjunction with accompanying drawing, the utility model is done to detailed introduction:
With reference to accompanying drawing 1, the utility model forms by demarcating frame 1, flexible member 2, standard LOAD CELLS 3, guide pole 4 and weighing system 5.
Wherein, weighing system shown in accompanying drawing 2, it comprises Weighing module 51, continuous jacking gear 52 and frame 53, wherein Weighing module 51 is positioned over continuous jacking gear 52 tops, Weighing module 51 and continuous jacking gear 52 are placed in frame 53, Weighing module 51 is connected with the guide pole 4 of caliberating device, and continuously jacking gear 52 loads for load, and frame 53 is for the fixing demarcation frame 1 of caliberating device.
The on-line proving device principle of work of the present embodiment is as follows:
During rating test, flexible member 2, standard LOAD CELLS 3 and guide pole 4 are connected successively to settle and be fixed on and are demarcated in frame 1, by demarcating frame 1, be bolted on the frame 53 of weighing system, jacking gear 52 extremely contacts and provides continuous loaded load by Weighing module 51 jackings with the guide pole 4 of caliberating device continuously.Guide pole 4 is delivered to loaded load standard LOAD CELLS 3, flexible member 2 and finally is delivered to and demarcates on frame 1, thereby realizes that opposite-compacting type elasticity loads continuously.Utilize continuous jacking gear 52 in weighing system to load continuously, make Weighing module 51 and standard LOAD CELLS 3 measure respectively the continuous load data, and will be separately measuring-signal pass to computing machine and process, by the mode of least square method and multiple spot curve, realize the high-precision calibrating of Weighing module 51.Because flexible member 2 absorbs instantaneous loading impulsive force, play buffer action, reduced the error of the output measurement data of standard LOAD CELLS 3 and Weighing module 51, improved the calibration measurements precision.
Above-described embodiment only is explanation technical conceive of the present utility model and characteristics, and its purpose is to allow the person skilled in the art can understand content of the present utility model and implement according to this, can not limit protection domain of the present utility model with this.All within spirit of the present utility model and principle, any modification of doing, be equal to replacement, improvement etc., within all should being included in protection domain of the present utility model.
