The invention discloses a locomotive wireless charging device which comprises ground intelligent control equipment and locomotive on-board equipment. The ground intelligent control equipment is composed of a ground power supply, a wireless charge transmitting module, a ground sensor and a ground microcomputer controller, and the locomotive on-board equipment comprises a wireless charge receiving module and an on-board storage battery. The locomotive wireless charging device has the advantages that a special external charging cable is not required to be connected, a locomotive is only required to be stopped at a specified position, an operation of cable connection is saved, and a trouble of storing and differentiating various types of special charging cables is further avoided; the locomotive can be charged immediately when being parked; poor contact of a plug and a socket or potential safety hazards such as burning loss, electric leakage, personnel electric shock and fire disasters occurred when insulation of a wire is damaged can be avoided; locomotive equipment burning loss caused by a fault of ground charging equipment is avoided; and simultaneous charging for multiple locomotives can be achieved by only additionally arranging the wireless charge transmitting module, the cost is slightly increased, and the working capacity grows exponentially.
