Abstract

The invention provides a rail flaw detection vehicle capable of detecting flaws on top surfaces of rails. The rail flaw detection vehicle comprises a flaw detection vehicle, a flaw detection system, and a top surface flaw detection system, wherein the flaw detection vehicle travels on the rails; the flaw detection system is mounted on the flaw detection vehicle and is used for detecting the flaws in the rails; the top surface flaw detection system is mounted on the flaw detection vehicle and is used for detecting the flaws on the surfaces and the subsurfaces of rail heads 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 equipped with rail top surface damage detection. Background technique [0002] Rails are the foundation of railway transportation, and ensuring that the entire section of the rails is in good operating 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 the full section 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. The rail flaw detection vehicle is equipped with an ultrasonic detection system to detect internal damage of the rail. Damage will affect the incidence of ultrasound and affect the damage discrimination of ultrasound detection. It cannot meet the r...
