Description
Technical field
The present invention relates to the detection of railroad track rail welding quality, welded rails joint is put down on specially a kind of exclusion line
The method of straight degree detection erroneous judgement inducement.
Background technology
Railway uses Jointless Track Design more, after newly-built gapless track or existing gapless track overhaul, before operation is opened
Welding point glacing flatness quality testing will be carried out, the accuracy of glacing flatness detection is directly connected to the safety and rail of train operation
Road structure service life.On line（Scene）The detection of steel rail weld joint glacing flatness typically uses the straight chi of electronics, to detecting
Underproof joint is handled, conventional processing method mainly have polishing, thermal straightening and saw rail rewelds, wherein saw rail reweld by
Increase line joint quantity, and substantial amounts of rail material and artificial can be expended, cause the increase of cost, while rail welding connects
Head is more, and line security hidden danger is bigger.Therefore, the accuracy that steel rail weld joint glacing flatness detects on line is most important.
At present, China railways are existing《Standard》With《Specification》Welded Joints glacing flatness detection technique condition and method do not have
Specific requirement is specified, actually detected result is disturbed by factors such as line conditions, snap fit part installment states, often can be to Site Welding
The glacing flatness testing result of joint has a direct impact, and causes False Rate to raise.
Therefore, there is an urgent need to develop a kind of " method for excluding steel rail weld joint glacing flatness detection erroneous judgement inducement on line ",
The accuracy of steel rail weld joint glacing flatness detection on line is improved, reduces False Rate.
The content of the invention
The present invention exists because line conditions, snap fit part are installed to solve steel rail weld joint glacing flatness detection on existing line
The problem of factors such as state influence glacing flatness accuracy in detection and cause erroneous judgement, there is provided one kind excludes welded rails joint on line
The method of glacing flatness detection erroneous judgement inducement.
The present invention adopts the following technical scheme that realization：Exclude welded rails joint glacing flatness detection erroneous judgement inducement on line
Method, using following steps：A, that detection is carried out into precision checking with electronics straight chi is qualified；B, some have determined that in field is examined
Survey qualified rail shop-welded connection and utilize the straight chi export oscillogram I of electronics under free state at the construction field (site)；C, choose and spread
The rail mother metal of some sections of keeping clear of joints of circuit, the ripple of the straight chi export rail of electronics is utilized under free state at the construction field (site)
Shape figure II；D, oscillogram I, oscillogram II are averaged to form the oscillogram III of qualified weld seam free state rail；E, respectively
Fixed some groups of rail shop-welded connections and some sections of rail mother metals on the line are chosen, measure its oscillogram and shape of averaging
Into the oscillogram IV of stationary state rail；F, by oscillogram III, IV using rail length as transverse axis, with rail surface or spigot surface
For vertical pivot, coordinate diagram is drawn by origin of weld seam；G, the rail at field welding joints is detected, and carried out with coordinate diagram
Compare, when detecting corresponding numerical value of the numerical value more than oscillogram IV, can directly be determined as that field welding joints glacing flatness is unqualified；
When detecting corresponding numerical value of the numerical value less than oscillogram III, it can directly be determined as that field welding joints glacing flatness is qualified；Work as detection
When numerical value is between corresponding numerical value of the oscillogram III with oscillogram IV, illustrate that the glacing flatness of field welding joints state is exceeded,
Arranged first by circuit and toe load of fastening adjusts, eliminate influence of the extraneous factor to test result, row detection again after processing,
It is qualified to be determined as if numerical value is up to standard, if data are not still up to standard, then is determined as unqualified.
It was verified that after factory's weldering acceptable splice and the laying of rail mother metal are fixed, shape often is installed by railway roadbed flatness, fastener
The influence of state, cause glacing flatness detection numerical value exceeded, standard can be reached by circuit arrangement, utilize railway roadbed flatness and fastener
The external influence factor of state causes the average exceeded scope of qualified welding point detection numerical value, as judging field welding joints
Whether qualified indirect criterion, avoid qualified field welding joints being directly mistaken for unqualified.
The process employs control variate method, which kind of influence observation variable produces on result, it is determined that being adopted in detection process
Cause the variable of results change with elimination or control, so as to obtain most real measurement result, specially analyze circuit and put down
Compliance and snap fit part installment state, according to analysis result, have formulated glacing flatness detection to influence caused by glacing flatness testing result
When line on the technical conditions that should possess of steel rail weld joint, so as to eliminate the factor for causing erroneous judgement, overcome on existing line
The detection of steel rail weld joint glacing flatness is present because the factors such as line conditions, snap fit part installment state influence glacing flatness accuracy in detection
And the problem of judging by accident.
The methodological science of exclusion erroneous judgement inducement of the present invention is effective, easy to operation, can effectively avoid because glacing flatness
Detection is judged by accident and carries out weld seam amendment or even saw the problem of rail welds again, reduces railways train operation hidden danger.
Embodiment
The method for excluding welded rails joint glacing flatness detection erroneous judgement inducement on line, using following steps：A, detection is used
Electronics is straight, and chi progress precision checking is qualified；B, some have determined that is detected into qualified rail shop-welded connection at the construction field (site) in field
The straight chi export oscillogram I of electronics is utilized under free state；C, the rail mother metal for some sections of keeping clear of joints for spreading circuit is chosen,
The oscillogram II of the straight chi export rail of electronics is utilized under free state at the construction field (site)；D, oscillogram I, oscillogram II are made even
Average forms the oscillogram III of qualified weld seam free state rail；E, fixed some groups of rail factories on the line are chosen respectively
Plumb joint and some sections of rail mother metals, measure its oscillogram and average to form the oscillogram IV of stationary state rail；F, will
Oscillogram III, IV using rail length as transverse axis, using rail surface or spigot surface as vertical pivot, by origin of weld seam draw coordinate diagram；
G, the rail at field welding joints is detected, and compared with coordinate diagram, when detection numerical value is more than oscillogram IV's
