Perforating device for in-pile pipeline of pool type reactor

The utility model relates to a perforating device for in-reactor pipelines of a pool type reactor. The perforating device comprises a first supporting frame, a vertical hanging bracket, a first driving mechanism, a second driving mechanism and a drill bit assembly, wherein the first supporting frame is transversely arranged at an opening in the upper portion of a reactor pool; the vertical hanging bracket extends in the vertical direction; the upper end of the vertical hanging bracket is connected to the first supporting frame to be hung in the water piling pool, the first driving mechanism is connected to the lower end of the vertical hanging bracket, the second driving mechanism is connected to the first driving mechanism, and the drill bit assembly is connected to the second driving mechanism; the second driving mechanism is used for driving the drill bit assembly to move in the first direction close to or away from the in-pile pipeline. The first driving mechanism is used for driving the second driving me
