[0002] In recent years, with the rapid development of the transportation industry, track measurement technology has been widely used in various rail transportation systems and projects. Track measurement technology refers to a technology that determines the geometric parameters of the track, the position of the track, and the deformation of the track by measuring the relative position between the wheel and the track.

The grooved track measuring instrument combines the device for measuring coordinates with the device for measuring the track gauge, so as to realize the convenient and rapid measurement of the track gauge, coordinates and other geometric parameters of the track.

[0004] However, the existing track measuring instruments need manual or other tools to measure the track, resulting in slow measurement speed. Sometimes the track cannot be detected due to the influence of climate. The existing track measuring instruments measure the track distance by saw ruler and then feed the data back to the computer. However, the data obtained by mechanized ruler measurement is not accurate enough. For this reason, we propose a portable track measuring instrument. Utility Model Content
