Locomotive braking ground electromagnetic signal device

The utility model discloses a locomotive braking ground electromagnetic signal device. The device comprises a locomotive magnetic inductor arranged on a locomotive, a strong magnet assembly matched with the locomotive magnetic inductor, an adjusting assembly for adjusting the strong magnet assembly, a placing assembly for placing the adjusting assembly, and a fixing assembly for fixing the placing assembly on a guide rail, and the locomotive magnetic inductor reacts with the strong magnet assembly. Through transmission of the electric cylinder and the gear, the magnet support is driven to rotate, the strong magnet can be sensed by a locomotive sensor when located above, electromagnetic signals can be matched when the shielding plate is located above, the locomotive sensor cannot sense the electromagnetic signals, and therefore switching of two states is achieved; the purposes of intelligently adjusting whether the tractor is braked or not and improving the driving safety of the tractor are achieved. 本实用新型公开了一
