Description

technical field [0001] The invention relates to the technical field of rail flaw detection, in particular to a dual-rail rail ultrasonic flaw detection and image monitoring integrated system and method thereof. Background technique [0002] When the train is running, it will cause friction, extrusion, bending and impact on the rails. Under these repeated actions, the rails are easily damaged. In order to ensure the safety of rail traffic, detect and monitor the occurrence and development of damage, the engineering department attaches great importance to rail flaw detection and track line monitoring, and has formulated relevant technical regulations and methods. [0003] At present, my country mainly adopts three methods for rail flaw detection: one is to use a large-scale rail flaw detector; the other is to use a hand-push rail flaw detector; The double-track ultrasonic flaw detector for rails has high detection efficiency, suitable for skylight flaw detection, moderate spee...

AI Technical Summary

Problems solved by technology

These conditions restrict the integrity of rail detection, and flaw detectors using dual-track rail ultrasonic flaw detectors cannot fully obtain the internal and surface conditions of rails at the same time

At present, the large-scale rail flaw detection vehicles in the market have the function of monitoring the rail surface, but it is different from the existing double-track rail flaw detection vehicles; and the small hand-push flaw detection instruments, because of their low speed, use visual inspection. Instant view of rail surface

[0004] The solution of the present invention is an invention aimed at the above problems. The existing double-track rail ultrasonic flaw detector can only conduct internal flaw detection and cannot perform synchronous rail surface monitoring.
