The invention provides a portal frame. The portal frame comprises a frame body, a lifting device, a rolling assembly and a shaft body. The number of the frame bodies is two, and each frame body comprises a supporting frame. Each frame body is provided with a lifting device, each lifting device comprises a first lifting assembly, a second lifting assembly and a bracket, one end of each bracket is connected with the corresponding first lifting assembly, the other end of each bracket is connected with the corresponding second lifting assembly, and the first lifting assemblies and the second lifting assemblies synchronously drive the brackets to ascend and descend. The first lifting assembly and the second lifting assembly are both arranged on the supporting frame. Each frame body is provided with a rolling assembly, and the rolling assemblies are arranged on the brackets. The two ends of the shaft body are connected with the rolling assemblies on the two frame bodies respectively, the rolling assemblies drive the shaft body to rotate, and the lifting device drives the shaft body to ascend and descend. Due to the fact that the portal frame is provided with the rolling assembly, the rolling assembly is arranged on the bracket, and the rolling assembly can roll while the lifting device ascends and descends, so that the portal frame drives the shaft body to rotate in the scene where rolling is needed.
