The invention discloses a dismantling device for a negative ring segment and a dismantling method of the negative ring segment. The negative ring segment is provided with a bolt connecting hole, the bolt connecting hole penetrates through the position between the inner ring face and the end face of the negative ring segment, the dismantling device for the negative ring segment comprises a bearing plate, an inserting and connecting bent rod and a locking and fixing piece, wherein the supporting plate is provided with an opposite first side and a second side used for being attached to the end face of the negative ring segment, a hoisting lug plate is installed on the first side of the supporting plate, a hoisting hole is formed in the hoisting lug plate, the inserting and connecting bent rod is used for being arranged in the bolt connecting hole in a penetrating mode, the first end of the inserting and connecting bent rod is installed on the second side of the supporting plate, and the locking and fixing piece is used for pressing against the inner ring surface of the negative ring segment and is installed at the second end of the inserting and connecting bent rod. According to the dismantling device for the negative ring segment and the dismantling method of the negative ring segment, the problems that the construction cost is increased due to the prolonged operation period when a traditional negative ring segment is lifted out through a lifting belt, and the consumed time is long are solved.
