Title:
STEEL RAIL REPAIR POST-TREATMENT STRATEGY MAKING METHOD
Document Type and Number:
WIPO Patent Application WO/2023/124583
Kind Code:
A1
Abstract:
A steel rail repair post-treatment strategy making method, comprising: acquiring laboratory repair data and online repair data in an actual working condition, correcting an ideal reference value by using the online repair data in the actual working condition, and mutually complementing by the laboratory repair data and the online repair data to finally obtain steel rail repair result data; respectively collecting and summarizing repair data of different road sections, then calculating parameters after steel rail repair under different road conditions and different road sections, and performing quality grading on steel rail repair results according to impact weights of these parameters on steel rail service reliability and lowest requirements on the parameters; and then comparing grinding data of a repair vehicle with a database, and making different solutions. The steel rails which are evaluated to be unqualified are respectively subjected, according to quality grades, to two treatment modes of secondary grinding by the repair vehicle and manual repairing, and the problems that after the steel rails are repaired, quality evaluation is not accurate, and a post-treatment strategy cannot be made rapidly are solved.
