Description

Technical Field

[0001] The utility model relates to the technical field of track measurement, in particular to a track measurement device. Background Art

[0002] In railway track construction, track measurement is the basis for ensuring the smoothness of train operation. If measurement and control are not carried out in a timely manner during the construction process, hidden dangers will occur during operation.

[0003] In conventional track measurement operations, track surface elevation and track direction are measured using a total station prism or RTK. For example, in the process of track direction measurement, the traditional method uses coordinates for layout. By placing the designed coordinate points, a steel tape measure is used to measure whether they are at the center of the track, and each section is compared one by one.

[0004] According to existing requirements, if the above-mentioned measurement method is used, the construction measurement efficiency will be seriously restricted, and workers need to be separately assigned to use steel tape measures for comparison. According to the existing statistical performance, the track direction and track surface elevation of a single-line track are measured, which seriously restricts the measurement efficiency. At the same time, at the connection with the existing railway station, there are railway switches and multiple tracks. More measuring instruments and personnel are needed to meet the construction time of the skylight points, resulting in low track measurement efficiency and the need to allocate more personnel to participate in the measurement work.

[0005] To this end, we propose a track measurement device. Utility Model Content
