The invention provides a carrier roller drive device. The carrier roller drive device comprises a slowdown motor, a universal coupling and at least two drive shafts which are sequentially connected, wherein the drive shafts are connected through the coupling, each drive shaft is sleeved with two bearing pedestals and two drive sprockets, and each drive sprocket drives a driven sprocket on a carrier roller through a chain. The carrier roller drive device provided by the invention is reliable in structure and simple and easy to operate, and the simultaneous rotation and stopping of all carrier rollers in operation under the driving a slowdown motor is realized, thereby reducing the occurrence of a situation that the surfaces of hollow billets are scratched because carrier rollers are not synchronized in the prior art. Because the slowdown motor is arranged away from a high-temperature billet, the damages caused by high-temperature burning are avoided, thereby reducing the number of required spare parts. Therefore, the production cost can be reduced while the production efficiency can be improved.
