The invention provides an emergency rescue device for an airplane. The emergency rescue device comprises a traction rod 1, a hydraulic lifting system 2, a support platform 3, a traveling mechanism 4 and a wheel holding mechanism 5, wherein the platform surface of the support platform 3 is C-shaped; a universal support wheel 33 is arranged on the front end of each of two prongs 3; the support platform 3 is connected with the traction rod 1 through a hinging structure; the hydraulic lifting system 2 comprises an oil pump 21, a high-pressure oil pipe 22, a hydraulic cylinder 23 and a connecting rod mechanism 24, wherein the connecting rod mechanism 24 is arranged on the rear ends of the two prongs of the support platform 3; the connecting rod mechanism 24 is connected with the traveling mechanism 4 and is used for converting a horizontal pushing force of the hydraulic cylinder into a downward pushing force of a main axle through a lever principle, so that the traveling mechanism 4 moves downwards, and the lifting of the support platform 3 is realized; wheel holding brackets of the wheel holding mechanism 5 are arranged on the platform surface of the support platform 3 and used for stably holding wheels to effectively prevent the wheels from sliding off, and thus the connection reliability of the emergency rescue device and the wheels of the airplane is ensured in a dragging process. The emergency rescue device provided by the invention has the effect of simple structure and is easy to operate.
