An automatic turnover fence of an operation platform is characterized in that a first longitudinal fixed rail post, a second longitudinal fixed rail post, a left fixed rail post and a right fixed rail post are fixedly installed on the rectangular operation platform; a first turnover fence body and a second turnover fence body are arranged on the first longitudinal fixed rail post and the second longitudinal fixed rail post through connection pieces; the tail ends of a first hydraulic cylinder, a second hydraulic cylinder, a third hydraulic cylinder and a fourth hydraulic cylinder which are of the same structure and the upper ends of piston rods are arranged on supporting bases through first pin shafts and second pin shafts in a hinged mode respectively. One ends of oil pipes of the same structure are connected to the first hydraulic cylinder, the second hydraulic cylinder, the third hydraulic cylinder and the fourth hydraulic cylinder respectively, and the other ends of the oil pipes are connected to oil inlet and outlet pipe openings of hydraulic control valves arranged on a locomotive respectively. The turnover fence can be overturned through the hydraulic oil cylinders and the connection pieces. The automatic turnover fence is reasonable in structure, high in automation degree, convenient to operate and capable of solving the problems that the labor intensity of operation workers is high and potential safety hazards are caused.
