Description
Technical field
The present invention relates to a kind of survey instrument of trackwork surface evenness of online track traffic and preparation method thereof technical field.
Background technology
The current track train chief time is run on rail, causes wearing and tearing to rail, and the sedimentation on ground also can make track occur uneven grade for metaboly, and railway maintenance staff needs regularly check whether the workplace of track is straight and measures.Electric train is widely used in urban transportation, train operation is frequent, when maintenance personnel detect rail, when the steel ruler of existing detection of straight lines degree and flatness is placed on the raceway surface of presence, because steel ruler has conduction, contact the signal that can send and track have barrier with orbital plane, give the alarm, allow control center's mistake think it is the signal that train transmits, make false judgment, affect the normal operation of train.In addition, when summer temperature reaches 40 DEG C, train is frequently by rail, and rail maximum temperature can reach 70 ~ 80 DEG C, and common steel ruler can be too high because of guide rail temperature, cannot measure.
Summary of the invention
For the deficiency of above technology, the invention provides one there is insulativity, electric signal, high temperature can not be disturbed to melt and to be out of shape, easily measure, portable insulation ruler.The present invention also provides the method for making of this insulation ruler.
Object of the present invention is achieved through the following technical solutions:
For measuring the insulation ruler of online track traffic trackwork surface evenness, feature of the present invention is to include aluminium alloy blade, blade outside surface is formed with the nonconducting metal oxide insulating layer of one deck, is connected with insulation strip, with graduated scale on blade in blade measuring surface.
The material of insulation strip of the present invention is polyimide or PVC or epoxy resin or phenolics or polycarbonate or ABS or organic glass.Insulation strip is bonding or screw connects or pin is connected on blade.
Method for making of the present invention is as follows: aluminium alloy blade is put into chromatedsolution and carries out anodic oxidation, form one deck AL in aluminum alloy surface
2o
3, when DC voltage rises to 750V, when temperature is greater than 50 DEG C, oxide layer on surface of material is breakdown, and produce arc discharge, and produce instantaneous high-temperature 2000 DEG C, oxide film is after high temperature action, and tissue changes, and fused mass forms one deck with AL
2o
3for matrix and surperficial nonconducting metal oxide insulating layer, insulation strip is bonding or connect or be connected to pin the both sides measuring surface of blade with screw afterwards.
Thickness of insulating layer >=the 0.1mm of metal oxide insulating layer of the present invention, hardness >=3000HV.
The present invention engraves scale before carrying out anodized or after anodized on blade.
The present invention's ruler that insulate has heat insulation, insulativity at the metal oxide insulating layer of outside surface and insulation strip, and the material of aluminium alloy blade makes ruler lightweight and is easy to carry about with one and operates.Insulation ruler of the present invention solves the problem that online trackwork surface evenness is not easily measured, because insulation ruler is non-conductive, the plastic layer of insulation ruler measuring surface has insulation, high temperature resistant and low temperature, hardness is high, not easily deformation and fracture, lightweight, to be easy to carry about with one advantage, substantially increases work efficiency.Method for making of the present invention is ingenious convenient, and the anode oxidation method adopted effectively has cracked the conductivity issues of metal material, obtains surface insulation and indeformable metal ruler.
Accompanying drawing explanation
Fig. 1 is that the present invention is insulated the stereographic map of ruler;
Fig. 2 is the front view of Fig. 1;
Fig. 3 is the A-A sectional view of Fig. 2.
Embodiment
Content of the present invention is set forth further below in conjunction with Figure of description.
As shown in Figure 1, Figure 2, Figure 3 shows, aluminium alloy blade 1 outside surface of the present invention is formed with the nonconducting metal oxide insulating layer 2 of one deck, is connected with insulation strip 3, with graduated scale 4 on blade 1 in blade 1 measuring surface.In two measuring surface, the material of insulation strip 3 is polyimide or PVC or epoxy resin or phenolics or polycarbonate or ABS or organic glass, by bonding or connect with screw or be connected on blade 1 with pin.Insulation strip especially polyimide insulative bar has the high temperature resistant and indeformable performance that keeps out the cold, when summer outdoor temperature reach 40 DEG C, when rail temperature reaches 70 ~ 80 DEG C, ruler still not yielding, melt, when winter, cold outdoor temperature was low to moderate-35 DEG C, also draw, distortion can not be there is.Insulativity >=100K the Ω of this ruler, the linearity≤0.08m/1000mm in surveying work face, chi easy to use is long is generally 1m, also can be longer or shorter.
The insulate method for making of ruler of the present invention is as follows: aluminium alloy blade 1 is put into chromatedsolution and carries out anodic oxidation, form one deck AL in aluminum alloy surface
2o
3, when DC voltage rises to 750V, when temperature is greater than 50 DEG C, oxide layer on surface of material is breakdown, and produce arc discharge, and produce instantaneous high-temperature 2000 DEG C, oxide film is after high temperature action, and tissue changes, and fused mass forms one deck with AL
2o
3for matrix and surperficial nonconducting metal oxide insulating layer 2, afterwards by bonding for insulation strip 3 or connect or be connected to pin the both sides measuring surface of blade 1 with screw.Thickness of insulating layer >=the 0.1mm of metal oxide insulating layer 2, hardness >=3000HV.Scale on blade can be scribed before anodized or after anodized.
The nonconducting metal oxide layer of one deck formed at aluminium alloy blade outside surface noted earlier, also can adopt existing burning fabrication techniques, make the metal construction of oxide skin(coating) destroyed and non-conductive.Metal oxide layer hardness is higher, similar pottery.
Use the present invention to insulate ruler when measuring online traffic track workplace flatness, only plastic insulation bar 3 need be aimed to be measured of rail, detect wearing and tearing post gap with clearance gauge.Insulation ruler can not disturb track traffic signal, and cause signal to misinformate defeated, this ruler can be accurate to the detection of 0.08mm to steel rail straightness within the scope of 1m.
Insulation ruler of the present invention can be applicable to the roughness measurement under the orbital plane duty of the railroad track of presence, tramway, high-speed railway rail.
