According to the present invention, analysis is performed, wherein concrete crossties are arranged under the bending paths having the bending angle of more than 4 DEG on the rail before more than 10 years, and most of trains are coal conveying trains or empty trains, and a plurality of grain conveying trains and passenger and freight mixed trains; worn pad plates, damaged or frayed insulation bodies, loose fasteners, cast and loose supporting materials, excessive rail wear, and broken crossties are detected; the goal is to evaluate the data of the existing track inspection car (TGC) and whether other detection system technologies can locate the position of the RSA; the purpose is to determine whether the output data of the TGC can be used for detect the RSA; and with the rail wheel tread wear degree detection method, the defect misjudgement rate and the miss of detection can be effectively reduced, the position, the size and the depth of the rail wheel tread defect can be exactly detected, and the rapid and effective new approach with the characteristics of low cost and high detection precision is provided for the rail wheel tread wear degree surface defect detection.
Description
Technical field
The present invention relates to rail detection technique field, be specifically related to the detection method of rail tread wear intensity.
Background technology:
In the traffic transport industry of China, railway transportation plays irreplaceable effect.
Railway transportation is a kind of land transportation mode, with two parallel rail-guided trains.Railway transportation is wherein one
Plant maximally effective known land transportation mode.Rail is provided that dead smooth and the hard medium wheel by train is above with
Little frictional force rolls.So, the people in face can feel more comfortable aboard, and saves energy.If being arranged to work as, railway
Transport saves five to seventy percent energy when can deliver the passenger-cargo thing of same weight than road surface transport.And, rail can averagely disperse fire
The weight of car, makes the carrying force of train be greatly improved.
For ensure railway transportation safe, quick, except to rail high straightness, high heating strength and high-precision want
Outside asking, the surface quality of rail be it is also proposed more strict requirements.Surface defect is then to weigh Rail Surface quality
One important technology index, is also to ensure that the important leverage of railway operation safety.
In many cases, the RSA of commitment is easy to repair.Only need to remove rail and backing plate, with epoxy or poly-ammonia
The rail tread region that ester admixture is replacing damaged, and reset steel with new or improved fastener, seal and backing plate
Rail.But, the detection of RSA is extremely difficult in early days, especially estimates, because orthopole is inconspicuous under rail tread.
Summary of the invention
For the problems referred to above, the technical problem to be solved in the present invention be to provide a kind of reasonable in design, easy to operate, add work efficiency
Rate is high and the detection method of stay-in-grade rail tread wear intensity.
The detection method of the rail tread wear intensity of the present invention, it comprises the steps of
1, analyze: before more than 10 years, on track, under every bend being more than 4 °, be the most mounted with concrete sleeper；Major part is current
Train be all coal conveyor or empty wagons, more additional grain-transporting vehicles and train.Annual tonnage is more than 60mgt.By institute
Having coal conveyor to be all arranged on other circuit, this circuit only allows sky coal car to pass through.
2, the most serious abrasion caused concrete sleeper and loss are in fully loaded unit train shape of current period mostly
Become.
3, the rail Cant data that benchmaring car obtains are used to position and have the region of height Cant (Cant is more than
2 °).
4, engineering staff has overhauled these sections, and have selected wherein 22 for detecting system test and comparison.This
A little sections contain the track components such as the backing plate of damage, insulator and maybe will produce RSA or be in RSA in early days.Engineering staff exists
These places are all made that mark with milestone etc., in order to compare with remaining four kinds of detection technique and system.
5, BNSF is using Cant as the Section 1 index evaluating track component damaged condition, and sometimes Cant is also referred to as RSA.
When Cant is beyond limit value, have specialty inspection personnel to determine the basic reason of damage and best solution.Measure
The RSA degree of depth drawn translates into the rail gradient of equivalence, to compare with direct RSA measurement technology.
6, detect following items and record data and be uploaded to systematic analysis:
6.1, the backing plate of abrasion
6.2, damage or the insulator that galls
6.3, the fastener come loose
6.4, the support of casting absent-mindedness
6.5, rail excessive wear
6.6, the sleeper ruptured
6.7, train runs the load of generation beyond design balancing speed
The difference that the different data comparing differences between detection car demonstrates different system is the biggest.Benchmaring car with other is
Change and standard deviation between system cause both to have no way of comparing too greatly at all；Field test is before automatic measurement detects
Carry out showing between Cant and RSA, to there is certain the most unknown relation of absolute existence.
When BNSF Cant determines the issuable place of RSA, professional another the follow-up place carried out
Still in confirming local condition and numerous potential condition, which is the main cause causing the Cant value that exceeds the quata in detection.
Standardized data illustrates may be of value to display format to be made to compare to the conclusion using different detecting systems to draw
Relatively, including the measurement of fully loaded gauge, unloaded gauge measurement, gauge limits value and other software-driven data analysis method
When the present invention operates, target is whether to assess the data of existing track detection vehicle (TGC) and other detecting system technology
The position of RSA can be positioned.Its objective is to determine that can the output data of TGC be used for detecting RSA.Cant refers to rail introversion,
On track, normal gradient is that 1:40(is inside).
Beneficial effects of the present invention: reasonable in design, can effectively reduce defect False Rate and loss；Can accurately detect tapping
The position of rail thread defect, size and the degree of depth, provide a kind of low cost, detection essence for rail tread wear intensity surface defects detection
Spend high the most effectively new way.
