Abstract

The invention discloses a device for hoisting and overturning a conical shell, belongs to the technical field of machining, and is used for solving the problem that the outer surface of the conical shell is a variable-diameter curved surface, so that the conical shell cannot be reliably clamped and overturned by a conventional hoisting tool. The device structurally comprises a hanging bracket, and clamping assemblies used for tightly holding the conical shell are installed on the two sides of the hanging bracket through connecting mechanisms; the connecting mechanism is switched between the unlocking state and the locking state through drawing and rotating operation, and then the opening and closing state of the clamping assembly is regulated and controlled. The clamping assembly is designed to be of a double-diameter structure, and in the closed state, the center of the clamping assembly is enclosed to form a clamping space matched with the outer surface of the conical shell. The double-diameter clamping assembly capable of being opened and closed can be conveniently arranged from the side face of the conical shell in a sleeving mode, the clamping space matched with the outer surface of the conical shell is defined, and the problem that the lifting appliance cannot be stably arranged in the conical shell in a sleeving mode due to the particularity of a conical curved surface is solved.
