The invention discloses a fully-automatic suspension type two-dimensional electromagnetic shielding door wit arc-shaped guide rails, comprising a door frame (1), a door leaf (3) and a control system (15), wherein the door frame (1) is fixedly arranged on the side wall of a shielding room, and the periphery of the door frame is in seamless welding with a shielding body steel plate; the door frame (1) is externally provided with a supporting framework (5); a suspending-displacement device (8) for suspending the door leaf is arranged on the supporting framework (5); the door leaf (3) is arranged at the lower part of the suspending-displacement device (8); the suspending-displacement device (8) is provided with a motor and a synchronizing device (9); and the suspending-displacement device (8) controls the motor and the synchronizing device (9) to drive the door leaf (3) to do vertical and translational two-dimensional movement at the lower part of the suspending-displacement device (8). The fully-automatic two-dimensional electromagnetic shielding door disclosed by the invention has the advantages that the design is novel and reasonable, the performance is excellent, the operation is simple, the maintenance is convenient, the whole-process operation of the shielding door is automatic, the influence of the inertia of the large suspension type shielding door on the operating stability is avoided, the quantity of motors of the shielding door is less, the structure is more reasonable and the control is more reliable; due to the adoption of a knife-groove meshing mode and a pneumatic locking mechanism, accurate alignment and stable and reliable meshing of the door leaf and the door frame are ensured, the possible deformation of the door leaf and the door frame in use is furthest reduced, and high shielding effectiveness is ensured.
