AI Technical Summary

Technical Problem

The existing mechanical transmission drive method of wheel profile measuring equipment has problems such as complex structure, low accuracy, poor stability and high maintenance cost, which makes it difficult to meet the high precision and high efficiency requirements of modern railway operation and maintenance.

Method used

By adopting an electromagnetic induction linear drive method, the traditional mechanical transmission mechanism is replaced by an electromagnetic drive mechanism and a guide shaft. Combined with the closed-loop control of the magnetic scale and the reading head, the smooth linear motion of the measuring sensor is achieved, thereby improving measurement accuracy and stability.

Benefits of technology

The simplified device structure reduces mechanical clearances and vibration interference, improves measurement accuracy and operational reliability, and reduces equipment size and maintenance costs.
