The main purpose of adjusting track smoothness is as follows:

[0003] (1) Track geometric design: the geometric shape of the track has an important influence on the smoothness. The designer needs to consider the radius, super-elevation, transition curve and other factors of the track to ensure that the vehicle can smoothly transition during driving. Through reasonable geometric design, the smoothness can be improved, so as to reduce the lateral acceleration and axial force of the vehicle;

[0004] (2) Track maintenance and repair: regular track maintenance and repair work is crucial to ensure smoothness. Maintenance personnel need to check whether the geometric shape of the track meets the requirements and repair possible defects such as deformation, wear or damaged track in time. Regular maintenance can prevent irregular deformation of the track and improve smoothness.

[0005] Currently, the method for detecting and adjusting track smoothness is as follows:

[0006] (1) The method of using human eyes and manual adjustment needs to observe the condition of track smoothness by human eyes to guide the staff to adjust. This method has low adjustment accuracy and consumes time and effort;

[0007] (2) The method of using measuring trolley and manual adjustment needs manual adjustment and measuring trolley pushing to know whether the adjustment is in place.

Although the device adopts a foldable structure, it is still inconvenient to carry and the process is complicated.

[0008] (3) Chinese patent CN220749670U discloses a fixing device for assisting rail smoothness measurement. The single ball head universal connector can make the instrument base rotate at any angle, so that the infrared distance meter can rotate at any angle and measure the flatness of the steel rail in all directions. However, the device is limited by the integrity of the rail and needs to be measured, adjusted and rechecked repeatedly, which is time-consuming and laborious. In addition, the infrared distance meter is fixed on the rail and needs to be adjusted manually. UTILITY MODEL CONTENTS
