The invention discloses a three-wheel rotary buffering type efficient obstacle surmounting device for a trolley. The three-wheel rotary buffering type efficient obstacle surmounting device for the trolley comprises a walking wheel assembly, a spring assembly, a supporting rod (13), a rolling bearing (4), a lug plate connecting shaft (10) and a triangular plate connecting shaft (14). The walking wheel assembly is composed of three walking wheels (1), a triangular plate (3), fastening nuts (2) and walking wheel connecting shafts (15). The spring assembly is composed of sunk screws (5), a cavity bottom board (6), a cavity (7), a compression spring (8), a lug plate (9) and a dustproof gasket (12). Through alternate rotation of the three wheels, the trolley can surmount a small-gradient obstacle, damage to the strength of hubs and shafts by impact force is reduced in the wheel and roadblock collision process, the service life of the hubs is prolonged, the problem that the service life of hubs of an existing trolley is not long is solved, and the problem that the existing trolley is possibly overturned due to the fact that the existing trolley cannot efficiently surmount the obstacle is solved.
