The utility model provides a full -automatic pantograph of electric locomotive, belongs to metal underground mine electric locomotive equipment field for electric locomotive's automatic pantograph receives. Its technical scheme is: the utility model discloses a receive electric pressure spring drive main arm pole, auxiliary pole, slide and overhead line in close contact with to receive the electricity, main arm pole and auxiliary pole are remaining the wide -angle throughout with the overhead line to having avoided scraping phenomenons such as bow, parking and having taken place, the contact force is balanced between slide and the overhead line, has reduced the spark discharge who causes because of frictional force is too big and has damaged the scheduling problem, has reduced the consumption of slide simultaneously, the cost is reduced, separation motor, shaft coupling, spool and wire rope can accomplish the separation of slide, main arm pole, auxiliary pole and overhead line, electric rotary mechanism can realize the pantograph forward, rotatory backward. The utility model discloses rational in infrastructure, convenient operation have realized that metal underground mine electric locomotive receives the electricity automatic, have accumulated the technological reserve for unmanned electric locomotive's development in the pit.
