[0002] In railway line maintenance, the weak points affecting the quality of maintenance are mainly defects such as curves, turnouts, and rail joints. Among these, wear defects on curved rails are the most likely to occur. Therefore, measuring the curve versine of railway curves to check whether the curve's smoothness meets the requirements is a common and important task in rail transit.

[0003] For example, Chinese patent application number 202323588492.4 discloses a track versine measuring device, including a measuring ruler. The measuring ruler comprises a holding part and a measuring part, which are fixedly connected. The holding part has a groove for holding the track, with both side walls of the groove perpendicular to its bottom surface. The inner bottom surface of the groove is parallel to the top surface of the measuring part, and the distance from the inner bottom surface of the groove to the top surface of the measuring part is 16 mm. The top surface of the measuring part is provided with graduations. This technical solution can quickly and accurately locate the measurement position, ensuring the measuring ruler remains perpendicular to the chord, improving the accuracy of curve versine monitoring data, and enhancing train comfort and safety.

[0004] However, the following problems still exist in this technical solution: the size of the measuring part in this technical solution is fixed and cannot be adjusted according to the size of the railway track, which has certain limitations in its use. Utility Model Content
