Tank body assembling electric lifting system by flip chip method and hoisting method thereof

Abstract

The invention provides a tank body assembling electric lifting system by a flip chip method, wherein the tank body assembling electric lifting system by the flip chip method comprises a plurality of electric lifting devices distributed uniformly in the inner side of a cylinder body and an expansion ring fixed on the inner wall of the cylinder body; the expansion ring is an enclosed circular ring with a concave clamping groove; each electric lifting device comprises a rack and an electric inverted chain hanged on the rack; and the electric inverted chain is connected with an expansion ring hanging fixture which is provided with a clamping body adaptive to the concave clamping groove on the expansion ring. The invention provides the lifting system and the hoisting method, and also discloses a lifting method of the tank body assembling by the flip chip method. The lifting system and the hoisting method provided by the invention not only overcomes the defect that the cylinder body rotates automatically during the lifting process and leads to inaccurate positioning, but also electric control is adopted for the full-distance lifting, the lifting system and the hoisting method are simple and feasible, not only relieves the labor intensity, but also lowers the assembling cost, improves the working efficiency, and increases the operation convenience and quickness and safety.

Description

technical field [0001] The invention relates to tank assembly equipment and an assembly method, in particular to an electric lifting system and a lifting method for tank assembly by flip-chip method. Background technique [0002] Large-scale tanks are generally assembled and welded by several sections of cylinders. When assembled by the flip-chip method, each section of the cylinder needs to be lifted upwards, and then welded and assembled in sequence, and the cylinder is generally hoisted by a crane. This hoisting method is not only costly, but also in the hoisting process, due to the steel wire rope, the cylinder will rotate axially during the hoisting process, which requires other auxiliary measures to position the cylinder, which increases the The difficulty of work and the potential safety hazards of industrial accidents make the positioning of the cylinder body inaccurate after it is raised, which brings great inconvenience to the later welding and assembly; the assemb...
