The invention provides a rail flaw detection vehicle adopting an automatic centering manner. The rail flaw detection vehicle comprises a flaw detection vehicle, a flaw detection system, and an automatic centering system, wherein the flaw detection vehicle is driven on rails; the flaw detection system is mounted on the flaw detection vehicle and used for detecting flaws in the rails, and comprises detection wheels; the automatic centering system is mounted on the flaw detection vehicle, and comprises an automatic centering sensor, an automatic centering control cabinet and an automatic centering driving motor, wherein the automatic centering sensor is used for detecting deviations between the detection wheels and the center line of the rails and sending a detection result to the automatic centering control cabinet; the automatic centering control cabinet is used for sending a control instruction to the automatic centering driving motor according to the detection result; the automatic centering driving motor is used for regulating the horizontal positions of the detection wheels and correcting the deviations between the detection wheels and the center line of the rails.
Description
technical field [0001] The invention relates to the technical field of rail transportation, in particular to a rail flaw detection vehicle adopting an automatic centering method. Background technique [0002] Rails are the foundation of railway transportation, and ensuring that the rails are in good condition is an important measure to ensure the safety of railway transportation. With the increase of my country's railway mileage and the increase of train speed, the requirements for rapid detection of rails are also gradually increasing. In China, a large-scale rail flaw detection vehicle with a running speed of 80 km / h is generally used for periodic inspection of rails, and the rail flaw detection vehicle is equipped with an ultrasonic detection system for flaw detection of rails. [0003] The ultrasonic rail flaw detection vehicle detects rail damage based on the ultrasonic echo reflected by the rail damage. When using an ultrasonic probe for rail flaw detection, the 0-deg...
