The present invention relates to a safety lifting device for a turbine inner case, which comprises: a tower unit (110) which is installed by making a vertical pillar (111) at the installation position of a lifting bar (10); an operating unit (120) including a moving frame (125) which is installed inside the vertical pillar (111) of the tower unit (110), and a moving plate (121) which is combined with the moving frame (125) in order to extend the lifting height; a lifting unit (130) which combines a wire rope (131) with the moving plate (121) of the operating unit (120), and extends the wire rope (131) downward at the top of the vertical pillar (111) in order to be combined with the lifting bar (10); a power transmitting unit (140) which combines a hydraulic cylinder (141) with the moving frame (125) of the operating unit (120) in order to push the moving frame (125) downward; a main supporting unit (150) which combines a supporting block (151) with the lower part of the vertical pillar (111) of the tower unit (110) in order to firmly support the standing state of the vertical pillar (111); and a seating unit (160) which seats the supporting block (151) of the main supporting unit (150) on the bottom for firm fixation. The safety lifting device for a turbine inner case can significantly improve workability and safety by smoothly and safely separating an inner case with a heavy weight, and can improve work efficiency by rapidly separating or inserting the inner case inserted into the inner circumference. |
