The invention provides a large round steel billet loading reinforced support. The large round steel billet loading reinforced support comprises a transverse pad timber for bearing weight, steel belts, hidden blocks, bolts and rubber leather cushions, wherein the steel belts and the hidden blocks fixedly perform displacement in the horizontal direction, the hidden gears, the steel belts and the transverse pad timber are fixedly connected through the bolts, and the rubber leather cushions are capable of increasing friction. The large round steel billet loading reinforced support is developed for producing concentrated weight quality round steel billet railway vehicle loading and transportation for iron and steel enterprises, through the use of the combination of the transverse pad timber, the hidden blocks and the steel belts, problems of concentrated weight, longitudinal and transverse movement of round steel billets are solved, and the goal of railway safe transportation is achieved. The large round steel billet loading reinforced support makes full use of the transverse pad timber for bearing the weight, the steel belts and the hidden blocks, the bolts and the rubber leather cushions, wherein the steel belts and the hidden blocks fixedly perform displacement in the horizontal direction, the hidden blocks, the steel belts and the transverse pad timber are fixedly connected through the bolts, and the rubber leather cushions are capable of increasing the friction, and the steady transportation of the large round steel billets is achieved.
