Loading and unloading machine for boxcar

The invention discloses a loading and unloading machine for a boxcar. The loading and unloading machine comprises a travelling base plate, a slipping frame, a conveying inclined bridge, a rotary table, a cross turning machine, a telescopic conveyor, a lifting mechanism and an operating control system; continuous conveying of goods and materials in a relatively long distance from other conveyor on a platform to the boxcar and from the boxcar to the platform can be realized. According to the invention, the slipping frame is adopted, and travelling wheels does not need to enter the boxcar; the loading and unloading machine is high in adaptability to the height difference of the boxcar baseplate and the platform; transverse conveying distance can reach 5.5 m; one-side distance of the boxcar cannot reach 8 m generally; the spare distance is suitable for manual loading and unloading to a boxcar conveyor; as the cross turning machine is adopted, possibility of package dropping can be reduced or avoided; two motor wheels are adopted for travelling and turning; the loading and unloading machine is simple in structure, and convenient to operate; the conveying mechanization level of goods and materials in the boxcar is greatly improved; the operation efficiency is improved; the labor intensity is reduced.
