AI Technical Summary

Technical Problem

The prior art is difficult to monitor the changes in the gap gap between the switch machine in real time, especially the displacement changes caused by vibration when the train passes, which affects the safety of railway transportation.

Method used

A switch machine notch monitoring device is designed, including a display rod, a cylinder, a monitoring mechanism, an auxiliary positioning mechanism and a self-locking mechanism. The monitoring mechanism detects the displacement changes of the indicator rod in real time, and the auxiliary positioning mechanism increases friction resistance, and the self-locking mechanism realizes the ultimate self-locking of the indicator rod.

Benefits of technology

Real-time monitoring of the gap gap between the switch machine is achieved, ensuring that displacement changes can be detected in a timely manner when the train passes, avoiding the gap gap exceeding the standard, and ensuring the safety and reliability of railway transportation.
