Steel cylinder overturning protection device

A steel cylinder overturning protection device comprises two overturning frames, the two overturning frames are the same in structure and are rotationally installed on the left side and the right side of a recycling vehicle rack in a bilateral symmetry mode, and a plurality of steel cylinder bottom brackets arranged front and back at intervals are fixedly arranged at the bottoms of the overturning frames. A plurality of clamping mechanisms used for clamping the necks of the steel cylinders are fixedly arranged on the top of the overturning frame, and the steel cylinder bottom brackets and the clamping mechanisms are arranged in a one-to-one up-and-down correspondence mode. When the steel cylinder overturning device is suitable for overturning the steel cylinder, the steel cylinder can be effectively prevented from being laterally overturned, the safety of inflating the steel cylinder is greatly improved, the problem that the overturning of the steel cylinder is difficult to realize is structurally solved, the
