Online detection method for weld joint alignment tolerance of steel rail
The invention provides an online detection method for the weld joint alignment tolerance of a steel rail. In the moving process of the steel rail, the infrared temperature measuring sensor is used forsensing the existence of a high-temperature welding seam so as to remove welding slag. The infrared thermal imaging sensor is used for sensing the position of a high-temperature welding seam, to perform data acquisition on the steel rail contour. The weld joint center position is obtained through the collected three-dimensional point cloud data, and the measurement points are used for calculatingthe misalignment amount, so that the misalignment amount of the two sides of the high-temperature hot weld joint is measured in real time in the steel rail movement process, the influence of artificial subjective factors during manual measurement is reduced, measurement data is objective and real, and measurement is accurate and reliable. In the detection process, a high-temperature weld joint isautomatically detected, welding slag on the two sides is removed, and the labor intensity of workers and the risk of being scalded are reduced. The steel rail welding quality is clear at a glance byautomatically drawing contour curves of the tops and the two sides of steel rails on the two sides of a hot weld joint.
本发明提供了一种钢轨焊缝错边量在线检测方法，本发明通过在钢轨运动过程中利用红外测温传感器感知高温焊缝的存在以进行焊渣的清除，利用红外热成像传感器感知高温焊缝的位置，以对钢轨轮廓进行数据采集，通过采集的三维点云数据获取焊缝中心位置以及测量点进行错边量的计算，从而实现在钢轨运动过程中实时测量高温热焊缝两侧的错边量，减少了手动测量时人为主观因素的影响，且测量数据客观真实，测量准确可靠。在检测过程中，自动检测高温焊缝并清除两侧焊渣，降低了工作人员的劳动强度和被烫伤的风险；通过自动绘制热焊缝两侧钢轨顶部和两侧的轮廓曲线，钢轨焊接质量一目了然。
