The invention relates to the field of petroleum drilling well repair devices, in particular to a variable-angle catwalk driving cart. The variable-angle catwalk driving cart comprises a base, a power device, a transmission shaft and a connecting piece used for being connected with a lug plate on the lower portion of a variable-angle catwalk. The power device and the transmission shaft are arranged on the base, and the power device is connected with the transmission shaft in a rotating mode. Advancing wheels used for being matched with transmission pieces fixed to a support guide rail of the variable-angle catwalk are arranged at the two ends of the transmission shaft. The connecting piece is arranged on one side of the base in the advancing direction. Compared with an existing driving method, the size of the variable-angle catwalk driving cart can be greatly reduced, and the variable-angle catwalk driving cart is more convenient to use in practice.
