The high energy ion beam accelerated by laser has the characteristics of small size, narrow pulse width and good directivity, so it has many potential applications. This work will introduce the beam line dynamics design of a laser driven proton radiotherapy planned to be completed by Peking University. The beam line will be used as the key system of the laser proton radiotherapy application demonstration device, and the beam transport system will complete the follow-up operation. The whole beam design can provide horizontal and vertical irradiation modes respectively. It can efficiently collect the large divergence beam generated by the laser. It also contains a complete energy selection system, which can effectively select the energy dispersion of the laser accelerated beam to meet the application requirements. Finally, the beam accelerated by laser passes through the beam transport system to provide a proton beam with a diameter of less than 5 mm and an energy propagation of less than 5\% at the horizontal and vertical irradiation targets.
