The invention belongs to the technical field of nuclear power plant equipment lifting transportation, and particularly relates to a falling-proof device in a lifting transportational process of a nuclear power plant spent fuel transfer container. The falling-proof device aims to provide the falling-proof device in the lifting transportational process of the nuclear power plant spent fuel transfercontainer to overcome shortcomings of the prior art, wherein the falling-proof device provides a falling-proof measure for the lifting transportational process of the spent fuel transfer container. The falling-proof device comprises guiding wheels (1), a corrugated pipe layer (2), an outer frame (3), a base plate (4) and guiding wheel fixing bolts (5). The base plate (4) is a square with a concavemiddle, the outer frame (3) is arranged in a concave groove of the base plate (4), the corrugated pipe layer (2) is arranged in the outer frame (3), and the guiding wheels (1) are fixed to the base plate (4) through the guidi
