Abstract

The invention provides an online detection system for unfitness of butt joint of rail welding seams. The invention realizes automatic detection and measurement of unfitness of butt joint of high-temperature welding seams during rail operation by means of laser vision sensor technology, infrared thermal imaging technology, infrared temperature measurement technology and other technologies, and reduces the influence of human subjective factors during manual measurement, and is objective and true in measurement data and accurate and reliable in measurement. During the detection, the automatic detection of high-temperature welding seams and removal of welding slag on both sides can not only reduce the labor intensity and the risk of scald of workers, but also reduce the unnecessary wear of brushes used to remove welding slag and improve the service life. By automatically drawing the contour curves on the top and both sides of the rails on both sides of the hot welding seams, the welding quality of the rails can be seen at a glance. In addition, the automatic collection, storage and uploading of the rail data realize network management of rail welding seams quality.

Description

technical field [0001] The invention relates to the technical field of rail weld seam detection, in particular to an online detection system for the amount of misalignment of rail weld seams. Background technique [0002] With the rapid development of high-speed railways and the gradual improvement of passenger safety requirements, the importance of welding quality of seamless rails for high-speed railways is becoming more and more significant. The amount of misalignment of rail welds is one of the important indicators for evaluating the quality of rail welding. Improving the detection level of misalignment of high-temperature welds and the quality of seamless rails will help improve the smoothness of high-speed train operation and the safety of driving. [0003] At present, the measurement methods used by domestic rail welding bases to detect the amount of misalignment of rail welds are basically manual measurement, and the measurement tool is a corrugated ruler modified fr...
