Abstract
Measure insulating ruler of online traffic track working face roughness, including aluminum alloy blade (1), the blade surface is formed with one deck nonconducting metal oxide insulating layer (2), is connected with insulating strip (3), the scaled scale of blade (1) upper band (4) at blade (1) measurement face. This insulation ruler has been solved and has been difficult for the measuring problem in line track working face roughness, and because of insulating ruler on -conductive, the plastic layer that the face was measured to insulating ruler has insulatingly, high temperature resistant and low temperature, and hardness is high, non -deformable and fracture, and light in weight, the advantage of easily carrying have improved work efficiency greatly.
Description
Technical field
The utility model relates to a kind of survey instrument technical field of trackwork surface evenness of online track traffic.
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 utility model provides one to have insulativity, electric signal, high temperature can not be disturbed to melt and to be out of shape, and easily measures, portable insulation ruler.
The purpose of this utility model is achieved through the following technical solutions:
The insulation ruler measuring online traffic track workplace flatness includes aluminium alloy blade, and 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 described in the utility model is polyimide or PVC or epoxy resin or phenolics or polycarbonate or ABS or organic glass.Described insulation strip is bonding or screw connects or pin is connected on blade.Thickness of insulating layer >=the 0.1mm of described metal oxide insulating layer, hardness >=3000HV.
The utility model insulation ruler has heat insulation, insulativity at the metal oxide insulating layer of outside surface and plastic insulation bar, and the material of aluminium alloy blade makes ruler lightweight and is easy to carry about with one and operates.This insulation ruler solves the problem that online trackwork surface evenness is not easily measured, and 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, the advantage that is easy to carry about with one, substantially increases work efficiency.

Fig. 1 is stereographic map of the present utility model;
Fig. 2 is the front view of Fig. 1;
Fig. 3 is the A-A sectional view of Fig. 2.
Embodiment
The utility model content 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 utility model insulation ruler is formed with the nonconducting metal oxide insulating layer 2 of one deck, is connected with plastic insulation bar 3, with graduated scale 4 on blade 1 in blade 1 measuring surface.In two measuring surface, the material of plastic insulation bar 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.Plastic insulation bar 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 is not yielding, thawing still, 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 nonconducting metal oxide layer of one deck that the utility model is formed at aluminium alloy blade outside surface, 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.
When using the utility model to measure 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.
The utility model can be applicable to the roughness measurement under the orbital plane duty of the railroad track of presence, tramway, high-speed railway rail.
