Description

Rail flaw detection vehicle

Technical Field

The utility model relates to the technical field of rail flaw detection, in particular to a rail flaw detection vehicle.

Background

The flaw detector for railway track is used to detect various defects of rail head, rail web and rail bottom, and the flaw detector rolls on the tread of rail through the probe wheel and then the ultrasonic probe inside the probe wheel is driven into the rail through the coupling liquid by the sprayed coupling liquid to realize flaw detection. The coupling state between the detection wheel and the rail has the greatest influence on the ultrasonic flaw detection accuracy. In actual flaw detection, curve lines are always met, and oil coating and lubrication are needed for the rails so as to reduce the abrasion of the rails on the curve curves. Lubricating oil adheres to the rail surface and mixes silt near the railway, and finally the rail working face is mixed into the oil sludge with certain viscosity. The coupling influence of the oil sludge on the flaw detection wheel is huge, and the flaw detection precision is greatly reduced. The mud scraping mechanism in the prior art mainly aims at the oil mud on the rail tread (upper surface) to carry out mud scraping operation, and the actual oil coating operation mainly aims at the oil coating of the R angle on the inner side of the rail, and the main oil mud is adhered to the inner side of the rail (as shown in fig. 1, the oil mud is guided by A in the drawing) and the R angle on the inner side of the rail. The prior art cannot meet the desilting requirement in the flaw detection process of the flaw detector.
