Abstract: An in-advance drilling rig apparatus and a shield machine, relating to the technical field of tunnel construction, and used for solving the problems in the prior art that an in-advance drilling rig apparatus interferes with other mechanical structures during installation, and the construction progress is affected due to frequent disassembly and assembly during use. The in-advance drilling rig apparatus comprises a supporting assembly (110), a driving assembly (120), a rotating assembly (130), and an in- advance drilling rig (140); the in-advance drilling rig is connected to the free end of the rotating assembly; the rotating assembly is used for driving the in-advance drilling rig to deflect in a first direction when the in-advance drilling rig apparatus is in a first state, so as to form a working state of the in-advance drilling rig, and the rotating assembly is further used for driving the in-advance drilling rig to rotate in a second direction when the in-advance drilling rig apparatus is in a second state, so as to form a folded and stored state of the in-advance drilling rig. The in-advance drilling rig can be folded for storage, so that it is conducive to avoiding the problem of interfering with other mechanical structures, and frequent disassembly is not needed during use, thereby improving the adaptability of the in-advance drilling rig in a shield tunnel, ensuring the construction progress, and reducing the construction cost.
