Abstract
The invention relates to a method for accurately repairing metro curve rail corrugation. The method comprises steps as follows: the metro curve rail corrugation is accurately measured, high-accuracy grinding starts to be performed when the rail corrugation reaches 0.05-0.2 mm, and synchronous measurement is performed in the grinding process until a satisfying repairing curve is obtained. Compared with the prior art, the method has the advantages of low cost, good effect and the like.
Description
Technical field
The present invention relates to railway track and grind recovery technique field, particularly relate to the rail of subway bend corrugation recovery technique that a kind of radius of curvature is less.
Background technology
Railway track corrugation is ubiquitous a kind of rail failure form on world's rail track, and it is a kind of main damage type of rail tread.Railway track corrugation causes having shortened rail self life-span, has increased maintenance work amount and maintenance cost; Affect vehicle operating quality and degree of passenger comfort; Cause rolling stock abnormal running, make vehicle sections component greatly shorten service time; When serious, be even related to train operating safety.Rail of subway bend corrugation has caused massive losses to subway.But up to the present urban track traffic is not both at home and abroad also for the effective proprietary recovery technique of rail of subway bend corrugation.
Summary of the invention
Object of the present invention is exactly a kind of method that accurate reparation subway bend Rail corrugation is provided in order to overcome the defect that above-mentioned prior art exists.
Object of the present invention can be achieved through the following technical solutions: a kind of method of accurate reparation subway bend Rail corrugation, it is characterized in that, the method is: accurately measure subway bend Rail corrugation degree, in the time that wearing and tearing reach 0.05～0.2mm, start high-precision grinding, synchro measure in grinding process, until reach the satisfied curve of repairing.
Described accurate measurement subway bend Rail corrugation degree is to detect by laser range sensor, survey subway bend rail abrasion degree by laser range sensor, in the time that wearing and tearing exceed setting value, grinding subassembly is adjacent to subway bend rail, and moves back and forth and repair wearing and tearing along the retinue of subway bend rail.
When reaching 0.1mm, described wearing and tearing repair.
Described high-precision grinding is the active grinding of high accuracy, is specially and adopts abrasive grinding wheel repeatedly to polish at fray.
Described satisfiedly repair curve to be that laser range sensor records subway bend rail curve consistent with primitive curve.
Through studying for many years discovery, what rail of subway corrugation was the most serious is curve inner side track, accurately repairs in time the most necessary for surveying track in the most serious bend of rail of subway corrugation.But the method adopting is at present that reparation is just to start the 0.3mm-0.5mm degree of depth is even more to Rail corrugation, and examination after repairing is more coarse, equipment operating complexity, inefficiency, installation and transportation inconvenience, running cost is high, and grinding precision is low.
The invention provides a kind of method of accurate reparation rail of subway corrugation: only curve inner side Rail corrugation is accurately repaired, restorative procedure is that initiatively grinding adds accurate measurement, in the time of Rail corrugation 0.1mm, start to repair. through this kind of reparation, can be geometric progression and improve rail application life, substantially can reach normal operating condition to vehicle.
Compared with prior art, the present invention efficiently solves that steel rail grinding device is expensive, running cost is high; Before polishing, preparation is heavy, and the polishing operation time is long, and pass is many, corrective maintenance task weight, and operating condition requires harsh, cannot be for specifying the grinding of rail and the shortcomings such as solution in time that note abnormalities.
