The invention provides an engineering machinery railway running auxiliary device. The device comprises a rack, two hydraulic motors and four lifting devices, wherein a plurality of rail wheels are rotatably installed on the lower portions of the two sides of the front end and the rear end of the rack respectively; the two hydraulic motors are in transmission connection with the rail wheels; and the four lifting devices are used for lifting the bottom surface of a vehicle frame of an excavator or the bottom surface of an axle of a loader. Two brake devices I and two brake devices II are arranged on the rack and used for braking. When the engineering machinery railway running auxiliary device is used, the excavator or the loader can be used to hang the engineering machinery railway running auxiliary device on a rail, then the excavator or the loader runs to the upper portion of the rail, the bottom faces of the vehicle frame of the excavator or the axle of the loader are supported by thelifting devices, and the excavator or the loader is lifted to be separated from the ground. Then the hydraulic motors are controlled to drive the engineering machinery railway running auxiliary device to lift the excavator or the loader to run on the rail, and the engineering machinery railway running auxiliary device is mainly suitable for railway emergency maintenance work.
