Abstract

The invention discloses a method for automatically detecting defects of a high-speed rail box girder. The method comprises the following steps of: S1, transporting an automatic detection device of the high-speed rail box girder into a to-be-detected high-speed rail girder box in a hoisting manner; and S2, performing defect detection on the inner wall of the high-speed rail girder box. According to the method, automatic detection of the defects of the high-speed rail box girder can be realized, the detection speed is high, the efficiency is high, a worker is free from flaw detection in a high-risk, harsh and harsh working environment, the subjectivity of a detection result is avoided, and timely maintenance and powerful support can be provided for safe operation of the high-speed rail.

Description

technical field [0001] The invention relates to a method for realizing automatic detection of defects of high-speed rail box girders, and belongs to the technical field of detection of track defects. Background technique [0002] The operating mileage of my country's high-speed rail has reached 35,000 kilometers, accounting for about 70% of the global high-speed rail network. The elevated bridge can ensure the high smoothness of the high-speed rail line, so it is widely used in the construction of high-speed rail in our country. The box girder is a key component of the viaduct, which directly bears the train load transmitted by the high-speed rail track. Under the alternating action of complex factors such as reciprocating loads (such as frequent train operation), environmental changes (such as alternating changes in temperature and humidity), and sudden disasters (such as earthquakes), micro-fatigue cracks will occur in high-speed rail box girders. The development and acc...
