The invention relates to an emergency rescue trolley of an excavator. The electromagnetic adsorption assembly is arranged at the top of the walking trolley and is suitable for adsorbing the walking trolley to the bottom of a lower vehicle frame of the excavator; the two folding arm assemblies are symmetrically arranged on the walking trolley, and the movable ends of the folding arm assemblies are suitable for moving on the horizontal plane; the lifting assembly is fixed at the movable end of the folding arm assembly; the motor is fixed at the lifting end of the lifting assembly; the first switching disc is fixed with a shell of the motor and is suitable for fixing the motor and the lower vehicle frame; when the walking trolley is controlled to move to the excavator, the trolley is attracted to the lower vehicle frame through the electromagnetic attraction assembly, the motor is moved to the corresponding position through the folding arm assembly and the lifting assembly, the motor and the lower vehicle frame are fixed through the first switching disc, and a second switching disc at the output end of the motor is connected with a chain wheel of the walking trolley. And the motor drives the walking trolley to walk, so that the excavator can continuously walk under the condition of anchoring.
