AI Technical Summary
Traditional rail vehicle wheelset inner distance detection tools rely on manual operation, which makes it difficult to quickly adapt to the differences between different types of rail vehicles, resulting in low detection efficiency and a high risk of errors.
A wheel-set inner distance detection device for rail vehicles, including a laser rangefinder and an ultrasonic rangefinder, was designed. The device automatically adjusts the position and height of the detection tool using an electric push rod and a drive mechanism, and achieves accurate measurement by combining laser and ultrasonic ranging technologies.
It improves the accuracy and reliability of detection, can adapt to different wheel track and wheel height, reduces detection errors, and improves detection efficiency.
