Problems solved by technology

[0002] At present, the straightness of the railway track is detected mainly by observation and judgment by human eyes, and then corrections are made by tools such as crowbars. Human error is inevitable due to the interpretation by human eyes, and there are many intermediate links in the detection, which are affected by human factors. too large, less accurate
When measuring the string height, the traditional method is to draw the steel wire, and then use a ruler to measure the maximum string height. Due to manual alignment and human eye interpretation during measurement, and the downward deflection caused

Description

Technical field: [0001] The invention relates to the design and manufacture of measuring instruments, in particular to a device for detecting railway rails using laser light. Background technique: [0002] At present, the straightness of the railway track is detected mainly by human eyes observation and judgment, and then corrections are made by tools such as crowbars. Human error is inevitable due to the human eye interpretation, and there are many intermediate links in the detection, which are affected by human factors. Too large and less accurate. When measuring the string height, the traditional method is to draw the steel wire, and then use a ruler to measure the maximum string height. Due to manual alignment and human eye interpretation during measurement, and the downward deflection caused by the self-weight of the steel wire, this method must be considered. The correction value is more troublesome. In addition, there are many intermediate links between environmental...
