Description
Technical field
The present invention relates in the railway transportation to detect for the installation quality of rail, relate generally to the geometric parameter quality detection apparatus for rail, specifically is exactly a kind of novel Portuble push type track inspection car.
Background technology
Track circuit is the foundation in the railway transportation, its basic geometric parameter as: the correctness of gauge, superelevation, twist irregularity is for guaranteeing that railway operation safety has very important meaning.
The irregularity of track, gently then reduce track and rolling stock life-span, reduce passenger's ride quality, heavy then jeopardize traffic safety, cause derailedly, pernicious driving accident such as overturn, bring huge property and human loss to the passenger, this is the major issue that life-and-death matter, also is major issues such as railway transportation departmental head.
The speed-raising again and again of railway transportation, the speed of service of train is more and more faster, from per hour five, 60 kilometers bring up to per hour 140 kilometers, still more and more higher except that locomotive, vehicle being required high to the requirement of railway track.The geometric parameter correctness of railway track seems more and more important for the train safe of running at high speed.
Along with five speed-raisings comprehensively of railway, correspondingly strict more to the inspection of circuit geometric parameter, carried out one-shot measurement in every month by original circuit foreman's section, measuring point changes every month into and measures 2 times apart from 10M, and 5M is existing for measuring weekly 2 times at interval, at interval 3M.The large-scale track checking car of per season Railway Bureau carries out the repetition measurement inspection.
The method of traditional detection railway track be gauging rule by manual measurement, reading bends over to adjust at every turn, three steps one kowtowed, labour intensity is big, at the bottom of the efficient, has seemed unable to do what one wishes under the new situation in speed-raising.
The method of traditional detection railway track lags far behind the demand of train speed raising, also lags behind more and more advanced digital information management means.Railway transportation exists so unpredictable potential safety hazard like this, and this will constitute huge threat to the security of operation of following train.
