Technical Field

[0001] The utility model relates to a device for inspecting the position of a steel rail strengthening treatment spot, belonging to the technical field of steel rail treatment. Background Art

[0002] When high-temperature plasma is used to strengthen the top surface and the inner side surface of the rail, it is necessary to process along the length direction of the rail. After the high-temperature plasma is used to strengthen the top surface and the inner side surface of the rail, strengthening spots will be formed on the surface of the rail. In order to understand the quality of the strengthening treatment, it is necessary to check the position of the spots strengthened by high-temperature plasma. At present, when checking the position of the rail strengthening treatment spots, it is generally carried out by direct observation by the human eye. Due to the lack of reference objects, the probability of large errors in the inspection is relatively high. Therefore, it is necessary to design a rail strengthening treatment spot position inspection device that provides reference objects during the inspection process. Utility Model Content
