Description
Technical field
The present invention relates to automatic detection fields, refer in particular to one kind and are surveyed suitable for high-speed track engineering using laser displacement
Method away from principle detection track plates angularity.
Background technique
In order to ensure track slab construction quality, accelerate track slab pavement progress, need to detect the track plates of factory,
Examination and scene are detected when being laid with, and the lonitudinal warping of track plates is otherwise unqualified no more than 2mm.High-speed railway
To track geometry required precision high ride, high-comfort, the high security of operation just can guarantee in this way.By to having built up
The high-speed rail for being open to traffic and being currently running long rail accurate adjustment is investigated.In the construction of high-speed railway rail early period, track construction uses tool track
Method or section of track framework method carry out construction accurate adjustment, and seamless gapless line is re-layed after the completion of track slab construction.In long track accurate adjustment,
There are some precision to transfinite for the road bed board of construction molding, in order to meet high-speed railway to orbital forcing requirement.It must lead to
It crosses and replaces nonstandard fastener to solve the precision problem in construction.It is in construction if not in place to precision controlling, the button in later period
Very big waste is caused to construction cost in part replacement.If track plates itself warpage degree is excessive, accurate adjustment processing, which is also not achieved, to be wanted
The geometry smooth degree asked then judges that the track plates are unqualified.
Traditional track slab warping detection method is that 18 prisms are first installed on track plates track, then artificial with complete
Instrument of standing measures the elevation of 18 prisms one by one, then enters data into execl table and the warpage that algorithm obtains track plates is manually added
Degree, determines whether track plates are qualified with this.This kind of detection method manual operation error be big and low efficiency, one piece of track plates of every measurement
It needs 30 minutes, heavy workload, large labor intensity seriously affect construction speed and efficiency.Whole process is cumbersome and manual operation
Based on step, artificial mistake is easy to appear in numerous operations.High-speed rail construction market environment is at present almost without automation inspection
Measurement equipment quickly marches in international route in Chinese high-speed rail, is badly in need of a kind of automation and relatively intelligent detection device, Ke Yizhun
Whether the quality for really and quickly detecting track plates is qualified, and existing measurement method can only measure the elevation of single track every time,
Under efficiency is very low, a hour can only survey 15-20 block plate.
The detection of existing automation warpage also rests essentially within line detection, for detection body have for mobile phone, such as public affairs
" phone housing buckling deformation automatic checkout system and method " disclosed in the number of opening 104019758A.For plate, for example disclose
" a kind of bow warping degree detection machine and its detection method " disclosed in number 104475353B.For glass, such as publication number
" glass substrate wrapping online test method ", etc. disclosed in CN102519376B.There are no for the detection of track angularity
It records, the record of warpage automatic testing method is carried out especially for the track plates of high speed railway track.
