Description

Technical Field

[0001] The utility model relates to the technical field of carbon slide plate testing, and more specifically to a carbon slide plate wear testing device. Background Art

[0002] The carbon slide plate is a key component for the train to obtain electricity from the power supply contact network. It is installed at the top of the pantograph and directly contacts the contact network wire. It is usually made of graphite. Its function is to transmit the 1500V high-voltage electricity of the power grid to the train, and then convert the high-voltage electricity into 380V, 220V, 110V and other voltages through the inverter to provide power, air conditioning, lighting and other functions for the train;

[0003] Before the carbon skateboard is put into use, it is necessary to conduct a wear test on the carbon skateboard sample to determine whether its surface wear resistance can meet the use standard. The surface of the carbon skateboard is worn by the test device, and the wear resistance of the carbon skateboard is evaluated based on the wear amount and surface roughness.

[0004] The existing carbon slide wear test device generally uses a simple wear tool to wear the surface, which is difficult to achieve high-speed wear and continuous wear, resulting in low wear intensity; and it is difficult to simulate the changes in the wear path during actual use, resulting in poor wear test results. In view of this, we propose a carbon slide wear test device. Utility Model Content
