The present invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein, as those skilled in the art will be able to make similar modifications without departing from the spirit and scope of the present invention.

Referring to fig. 1, an embodiment of the present application provides a rail surface standard line adjusting device 10, including: a ruler body 11, a first pointer 12 and a second pointer 13. The ruler body 11 is provided with a scale 14, the first pointer 12 is arranged on the ruler body 11 in a sliding mode along the scale 14, and the second pointer 13 is arranged on the ruler body 11 in a sliding mode along the scale 14. The first pointer 12 and the second pointer 13 are arranged at intervals on two sides of the scale 14, and both the first pointer 12 and the second pointer 13 point to the scale 14.

When the rail surface standard line adjusting device is used, the device is hung on a wall and/or a column wall, so that the initial position scale line on the ruler body 11 is consistent with the initial rail surface height, and the initial height of the rail surface is determined. The power supply and engineering departments need to detect the rail surface height every year, the detection result can be represented by adjusting the position indicated by the first pointer 12 on the scale 14, and the annual rail surface height change value can be calculated by the difference value of the detection value and the initial rail surface height. Meanwhile, the department of industry will occasionally monitor the rail surface height change in real time, and it can indicate the latest measured rail surface height change by adjusting the position of the second pointer 13 on the scale 14. And after the position indicated by the second pointer 13 is adjusted by the engineering department according to the latest rail surface height value, comparing the difference value between the first pointer 12 and the second pointer 13, and if the difference value exceeds a specified numerical value, informing the power supply department of adjusting the height of the overhead contact system according to the real-time rail surface height so as to ensure the driving safety of the electric locomotive. The device utilizes the pointer to replace the conventional red line spraying mode, can avoid the phenomenon that the red line falls off due to weathering, and can accurately and stably record and display the height change condition of the rail surface; in addition, the device also has an early warning effect. Moreover, the scale 14 can visually reflect the difference between the first pointer 12 and the second pointer 13, so that the visualization degree of detection and the accuracy of the detection result are improved.

Further, the scale value 143 is provided along the length direction of the scale body 11, and the central value of the scale value 143 is 0. One end of the scale value of '0' is set as a positive scale value 1431, and the numerical value of the positive scale value 1431 gradually increases along the length direction of the ruler body 11 away from the scale value of '0'. The other end of the scale value of '0' is set as a negative scale value 1432, and the numerical value of the negative scale value 1432 is gradually reduced along the length direction of the ruler body 11 away from the scale value of '0'. In order to clearly indicate the rail surface height change by the rail surface standard line adjusting device 10, when the rail surface standard line adjusting device 10 is installed on a wall and/or a column wall, a scale value of "0" is used as a starting position for marking the rail surface height, and when the rail surface height is measured subsequently, if the real-time height of the rail surface measurement is lower than the initial height, the first pointer 12 and/or the second pointer 13 points to the negative scale value 1432. If the real-time height of the rail surface measurement is higher than the initial height, the first pointer 12 and/or the second pointer 13 point to the positive scale value 1431. And the amount of adjustment of the first pointer 12 and the second pointer 13 can visually reflect the rail surface height variation amount through the scale value 143.

When the rail surface standard line adjusting device 10 is used, the rail surface height is aligned with the scale value of "0", and at this time, the initial positions of the first pointer 12 and the second pointer 13 are both located at the scale value of "0". Therefore, the change condition and the change value of the rail surface height can be more intuitively seen by taking the scale value of 0 as the initial position.
