Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of rail transit equipment detection, and in particular to a pantograph carbon slide plate detection device and a carbon slide plate wear detection method. BACKGROUND

[0002] During the operation of high-speed rail, the wear phenomenon caused by the sliding friction between the pantograph carbon slide plate and the catenary in the continuous dynamic contact occurs at any time. As an easily worn part, the wear degree of the carbon slide plate greatly affects the safety and stability of high-voltage power obtained from the external power supply system. Therefore, in daily maintenance, if the thickness of the pantograph carbon slide plate is not detected in real time, when the wear degree of the carbon slide plate exceeds the defined safety threshold, it is likely to cause arc discharge, poor contact, or even power failure during operation, resulting in line shutdown, equipment damage, and even major traffic accidents, affecting people's property and life safety. Therefore, the detection of the wear degree of the carbon slide plate and timely replacement are key projects in the vehicle maintenance and maintenance process. Currently, the replacement of the pantograph carbon slide plate is mainly dependent on traditional manual maintenance. In the maintenance process, the manual top climbing operation mode combined with first-level maintenance and second-level maintenance is mainly used. For a subway maintenance base or a high-speed rail vehicle depot that needs to complete dozens of trains per day, the time ratio of the traditional manual maintenance of the pantograph in the entire maintenance process has become a bottleneck restricting the operation and maintenance efficiency. Since the pantograph carbon slide plate is the core component of the rail transit vehicle for obtaining power from the catenary, the long manual maintenance period will also reduce the operation and maintenance efficiency of the line. In addition, the manual maintenance combined with simple instrument maintenance on-site maintenance method cannot meet the accuracy requirements. The industry standard requires that the detection accuracy of the pantograph carbon slide plate should reach ±0.2mm, and the spatial positioning error of the related defects of the pantograph carbon slide plate in manual maintenance reaches ±15mm, which cannot accurately and effectively identify early defects such as fine cracks and local chipping, and is prone to cause excessive maintenance and insufficient maintenance, ultimately resulting in unnecessary waste of manpower, material resources, and financial resources.
