AI Technical Summary

Technical Problem

The existing tamping machine operation safety interlocking control system lacks a dedicated safety interlocking protection device for the measuring trolley derailment. This makes it easy for the tamping machine to experience problems such as inconsistent tracks between the measuring trolley and the main trolley or derailment under complex conditions such as harmful gaps in the turnout area and track size errors.

Method used

A derailment control device for a tamping car was designed, including a derailment control module, a movement control module, an early warning module, and a safety disconnect switch. The device uses a signal acquisition unit and a microprocessor to determine whether the tamping car has derailed, and controls the movement of the tamping car through the movement control module. The early warning module outputs an early warning signal, and the safety disconnect switch cuts off the connection in an emergency to prevent derailment accidents.

Benefits of technology

It effectively prevents tamping machines from derailing, ensures their safe operation, reduces mechanical damage and personal injury caused by derailment, and improves the safety and reliability of railway maintenance operations.
