Attached lifting scaffold device

An attached type lifting scaffold device comprises a main frame body, a foldable turning plate is arranged on the main frame body, pulleys are arranged on the two sides of the free end of the turning plate respectively, a chain block is hung on the main frame body, one end of the chain block is connected with a steel wire rope, and the other end of the steel wire rope bypasses the pulleys and is fixed to the main frame body. During use, the steel wire rope can be pulled by the chain block to control the turning plate to be opened to be in butt joint with the inner concave floor or folded to be overlapped with the main frame body. When used, the turnover plate capable of being folded can be unfolded to be in butt joint with the building body of the inner concave layer, and when not used, the turnover plate capable of being folded to be overlapped with the main frame body without affecting lifting of the scaffold, and therefore construction of the inner concave structure can be met, repeated disassembly and ass
