AI Technical Summary
Traditional rail alignment measurement methods are difficult to adapt to different rail models and installation scenarios, have unstable support, and have low measurement efficiency and accuracy, failing to meet the needs of efficient and precise rail alignment operations.
A rail alignment measuring ruler mounting bracket was designed, which includes a leveling mechanism, a laser, and a guide structure. It can accurately detect the rail height, adapt to different installation scenarios, and achieve automated data acquisition through a laser displacement sensor to ensure measurement stability and accuracy.
It improves the accuracy and efficiency of rail alignment, reduces human error, adapts to various scenarios, and enhances the efficiency and precision of rail installation and docking.
