Abstract
A kind of by surveying the non-contact measurer of rail nonstraightness that chi and data recording section are grouped into.As shown in Figure 3.The survey chi of this measuring instrument is made up of blade and electronic measuring part.Blade is made up of housing, seal cover and right leg.The electronic surveying part is made up of probe, power supply, non-contact displacement transducer, converter, attenuator, digital display, power switch and selector switch.Data recording unit is made up of analog-digital converter and printer.
The present invention adopts enclosed construction.It is similar to steel ruler commonly used to survey the chi profile.Measurement component adopts non-contact displacement transducer and converter thereof, and shows with numeral, is lastly recorded on the paper tape.
Description
The invention belongs to the non-contact measurer of rail nonstraightness that is shown as its feature with numeral.
This measuring instrument is suitable for being used for checking the nonstraightness on rail surface.At present, check that whether straight rail method a lot: domesticly generally adopt one meter steel ruler, lean against on the rail that to measure, with estimating or clearance gauge is checked.This method error in reading is big, and the measuring instrument that is used to detect the rail unevenness abroad has Russian Patent: how much non-planeness measurement instrument of rail track (patent No.: 949030).This measuring instrument is made up of framework, adjuster, vertical reference parts and horizontal reference parts.The measurement roller is arranged on the horizontal reference parts.Measure roller and adjuster and link, and in level and vertical plane, relatively move.Adjuster is placed on the vertical reference parts.Because of this measuring instrument has adopted contact type measurement, certainty of measurement is lower.
The purpose of this invention is to provide a kind of band numeral and show, and can write down the non-contact measurer of rail nonstraightness of rail nonstraightness numerical value.Measuring probe does not directly contact with rail.Therefore, in measuring process, greasy dirt, the moisture content of measuring the surface all do not have influence to measurement result.
The present invention is grouped into by surveying chi and data recording section.Surveying chi is made up of blade and electronic measuring part.Blade is made up of housing, seal cover and leg.Electronic measuring part is made up of probe, power supply, displacement transducer, converter, attenuator, digital display, power switch and selector switch.Power supply is formed by two groups.Power to converter for one group, another group is powered to digital display.Digital display is connected with attenuator.Electronic measuring part is contained in the blade of sealing.Make and survey the chi profile near general straight steel ruler, displacement transducer is contained in the housing middle part.Data recording portion is made up of analog-digital converter and printer.Printer is connected with analog-digital converter.Analog-digital converter is connected with attenuator in the housing through cable.
The present invention adopts enclosed construction, carries out non-cpntact measurement with non-contact displacement transducer and converter thereof, demonstrates the data of the rail nonstraightness of surveying with numeral, and these data are recorded on the paper tape.
Be convenient on-the-spot use, the power supply 6F in the electronic measuring part
22Stacking dry cell, and be placed in the housing.Power switch adopts does not have the lock uni-directional push-button switch.When the survey chi is placed on or leans against on the rail, do not have the lock uni-directional push-button switch and connect automatically, and measure.Digital display demonstrates measurement result.When the survey chi leaves rail, there is not the automatic disconnection of lock uni-directional push-button switch, powered-down.Therefore, use very power saving, convenience.Power supply is by one group of 4 joint 6F
22A stacking battery of 9V and a joint 6F
22The stacking battery of 9V is formed.The former supplies the converter electricity consumption by composition ± 18V power supply, and the latter is for the digital display electricity consumption.When the digital display power voltage insufficient, digital display shows LBT(LowBotter automatically).The purpose that selector switch is set be for check+18V and-the whether coincidence measurement requirement of 18V power source voltage.Avoid brownout, certainty of measurement is descended.Selector switch is a band switch.
Displacement transducer in the electronic measuring part is selected eddy current displacement sensor and converter thereof for use.Range is ± 2.5mm.When displacement be respectively+2.5mm and-during 2.5mm, converter is output as+2.5V and-2.5V.Digital display adopts 3 half liquid crystal panel tables.Because the maximum input voltage of panel table only allows ± 200mV, and total input voltage is ± 18V, therefore will carry out 100 times of decay.So added one 100 times resistance decrement network at the input of panel table.In attenuation network, adopted adjustable resistance, be used for adjusting survey chi precision.
When measuring nonstraightness, the numerical value that shows on the panel is exactly millimeter value, the i.e. numerical value of nonstraightness of displacement.When rail is straight, be shown as zero, epirelief is shown as "+", recessed be shown as "-".
Below in conjunction with accompanying drawing the present invention is described in detail as follows:
Fig. 1 is the front view of non-contact measurer of rail nonstraightness;
Fig. 2 is the upward view of non-contact measurer of rail nonstraightness;
Fig. 3 is the A-A sectional view of non-contact measurer of rail nonstraightness;
Fig. 4 is the circuit theory diagrams of non-contact measurer of rail nonstraightness;
Fig. 5 is the measuring system block diagram of non-contact measurer of rail nonstraightness.
The present invention forms by surveying chi 1 and data recording portion 2.Surveying chi 1 is made up of blade 3 and electronic measuring part 4.Blade 3 is made up of housing 5, left seal cover 6, right seal cover 7, left leg 8 and right leg 9.Electronic measurement component 4 is selected for use by probe 19, power supply 10, displacement transducer 11, converter 12, attenuator 13, digital display 14, power switch 15(does not have the lock uni-directional push-button switch) and selector switch 16 form.Data recording portion 2 is made up of analog-digital converter 17 and printer 18.
Embodiment:
Before the measurement, each position of first check measurement instrument has or not abnormality.If no abnormal state can be connected power switch earlier, observe numeral and whether normally show.If no problem checks at last whether cell voltage meets the requirements.At last selector switch is dialled in the non-straightness measurement position.
During measurement, will survey chi and be placed on the rail surface reposefully, or lean against the rail side.In case two legs contact rail fully, power switch is promptly connected voluntarily.Can read the data of surveying from display window.Measure and finish, will survey chi and take away.Power switch disconnects voluntarily, and the demonstration numeral is died away.
