Regular online detection system for D-series high-speed train

Abstract

The present invention discloses a regular online detection system for a D-series high-speed train; devices such as an in-warehouse integrated overhauling platform, a moveable rim and spoke flaw detection system, hollow / solid axle flaw detection equipment, and portable rim and spoke flaw detection equipment are arranged on a primary overhauling line of the D-series high-speed train to jointly detect train bottom panorama, and visibility and dimension measurement of key components, and to comprehensively detect rim and spoke defects (namely tread images, out-of-roundness and three-dimensional measurement), solid and hollow axle flaw detection, portable defect combination and other faults, thereby ensuring the safety and reliability of the D-series high-speed train and realizing the safe andreliable operation of the running parts of the high-speed EMU.

Description

technical field [0001] The invention belongs to the field of EMU maintenance and detection, and in particular relates to a regular on-line detection system for EMUs. Background technique [0002] The structure of the EMU has the characteristics of complex structure, many parts, low height of the floor, and closed side skirts. During operation, most of them are high platforms, one-stop direct, long-distance turnaround, and the stop time is short, so it cannot In the middle of the process, inspect and overhaul the parts status of the bottom plate, bogie and skirt. It is difficult to confirm and detect the component damage caused by the impact of foreign objects in the operation process, and it is easy to cause the return operation of the EMU to run with diseases. Especially for EMUs running at a speed of 250 kilometers per hour on ballasted tracks, it is more likely to cause foreign objects to hit the bottom parts during high-speed operation, causing safety hazards to continu...

AI Technical Summary

Problems solved by technology

[0006] When the EMU is running at high speed, a small fault may also lead to a huge accident

Therefore, the high complexity of the EMU highlights the shortcomings of the traditional detection mode, and a new regular online detection method is needed to improve the comprehensive monitoring of the structural failure of the EMU.
