Non-contact type collector shoe carbon contact strip abrasion detection device and abrasion detection method

Abstract

The invention discloses a non-contact collector shoe carbon contact strip abrasion detection device and an abrasion detection method. The non-contact collector shoe carbon contact strip abrasion detection device comprises a first 3D camera, a second 3D camera and a processor, the first 3D camera is arranged above a third rail gap of the train, is connected with the processor and is used for collecting 3D information of the upper surface of a collector shoe carbon contact strip and transmitting the 3D information of the upper surface to the processor; the second 3D camera is arranged below a third rail gap of the train, is connected with the processor and is used for collecting 3D information of the lower surface of the collector shoe carbon contact strip and transmitting the 3D information of the lower surface to the processor; the processor is used for fusing the upper surface 3D information and the lower surface 3D information into a 3D model of the collector shoe carbon contact strip; and the processor is used for calculating the thickness of the carbon contact strip according to the 3D model and determining the abrasion loss of the carbon contact strip. According to the invention, the non-contact wear detection of the collector shoe carbon contact strip is realized by using the 3D imaging technology, so that the purpose of rapid and accurate detection without stopping can be achieved, and the method has high market promotion value.

Description

technical field [0001] The invention relates to the technical field of carbon slide wear detection, in particular to a non-contact carbon slide wear detection device and a wear detection method for collector shoes. Background technique [0002] The collector shoe, also known as the collector shoe or the collector shoe, is installed on both sides of the bogie frame of the vehicle near the middle of the outer side of the vehicle. It is put down when in use and put away when not in use. It is the contact between the subway EMU and the third rail. The collector device, and the carbon slide is the part on the collector shoe that is in contact with the third rail to receive electricity. The carbon skateboard will continue to rub against the third rail when it is in constant contact with the third rail to receive electricity, resulting in continuous wear of the carbon skateboard. Excessive wear of the carbon skateboard will lead to serious consequences such as power supply of the t...

AI Technical Summary

Problems solved by technology

The carbon skateboard will continue to rub against the third rail when it is in constant contact with the third rail to receive electricity, resulting in continuous wear of the carbon skateboard. Excessive wear of the carbon skateboard will lead to serious consequences such as power supply of the train and train shutdown. Therefore, the wear condition of the carbon skateboard Conduct monitoring and become one of the daily maintenance tasks of collector boots

[0003] At present, the wear detection of the carbon skateboard on the collector shoe is manually detected, which is not only time-consuming and laborious, but also needs to be detected when the train is stopped for maintenance.
