AI Technical Summary

Technical Problem

Existing track circuit testing fixtures cannot adapt to the differences in the location of tread wear marks on different track types, and the pressure application operation is physically demanding, lacking applicability and portability.

Method used

The clamping mechanism, made of lightweight aerospace aluminum alloy, combines a piezoelectric mechanism and a force-applying mechanism. Through a pressure multiplier and a nested screw structure, it achieves lateral adjustment of the piezoelectric head and precise pressure loading. Equipped with a pressure sensor and a force-measuring mechanism powered by a rechargeable battery, it ensures the stability and portability of the clamp.

Benefits of technology

It meets the precise testing requirements of different track types, reduces the need for operational force, ensures intuitive monitoring and stable output of pressure values, and has a compact fixture structure that is easy to carry and operate.
