Sliding electrical-contact abrasion test device

The utility mode belongs to a test device, in particular to a sliding electrical-contact abrasion test device, which consists of a mechanical unit and an electrical control unit. The mechanical unit comprises a left rack (2), a right rack (25), an auxiliary rack (29), a first motor (3), a second motor (30), a first belt pulley (4), a second belt pulley (6), a third belt pulley (19), a fourth pulley (30-1), a first belt (5), a second belt (20), a first bearing assembly (7), a second bearing assembly (11), and a third bearing assembly (18). The electric control part sends the testing data of the mechanical unit to a host computer, the data is processed after being controlled and converted by a singlechip, and curves are generated and the records are displayed; the sliding electrical-contact abrasion test device can effectively simulate the actual running condition between an pantograph slide plate and a contact conducting wire when a high-speed electric locomotive runs, display the detection amount through the host computer software in a real-time online digital manner, and generate various corresponding historical curves, and in addition, the test device has wide parameter adjusting range and high measuring precision.
