A safety device for a pylon includes an upper frame connected together with a lower frame, wherein both the upper frame and the lower frame includes two parallel steel pillars. fixedly connected together by a thick steel piece, the upper frame and the lower frame are connected through two parallel connecting rods to enable the upper frame and the lower frame to make relative motion. Two oblique safety grooves are respectively mounted on an inner side of the steel pillars and used for telescoping with specific-designed H-shaped safety rail. A connecting ring is mounted on the rear end of the safety device for providing the safety device to connect and slide with human body. In case of accident, the instantaneous force generated between the safety groove and the safety rail can stop the human body from falling and achieve the safeguard function.
