The invention discloses a structure and method for hoisting a stator of a large-scale power generator. The structure comprises a small portal, hoisting hooks and a hoisting jack line. The small portal comprises a lifting carrying pole, a first crane and a second crane. The hoisting hook of the first crane and the hoisting hook of the second crane are hung at the two ends of the lifting carrying pole correspondingly. A steel wire rope riding base is fixed to the center of the lifting carrying pole and connected with the hoisting hooks through steel wire ropes. The structure for hoisting the stator of the large-scale power generator is formed by main lifting systems of the two cranes and the lifting carrying pole, the two cranes are hard connected through channel steel, the two cranes and the lifting carrying pole form the small portal for hoisting the stator of the power generator, ground steering of the stator of the power generator is completed through the hoisting hooks, then fine adjustment of positions and stator in-place are carried out, and the structure and method are accurate and safe in hoisting and simple in process.
Description
technical field [0001] The invention belongs to the technical field of generator hoisting, and in particular relates to a stator hoisting structure for a large generator and a hoisting method thereof. Background technique [0002] With the improvement of the production and manufacturing technology of generating sets in my country, power plants have a tendency to gradually develop towards high parameters and large capacity. Especially in recent years, 600MW units have become the mainstream of the market. With the maturity of power installation technology, higher requirements are put forward for the installation period and safety control of generator sets. In the traditional hoisting process of the generator stator, the construction technology of installing four sets of hydraulic lifting devices on the top of the crane of the turbine room was generally used in the past units for hoisting. [0003] Transportation, hoisting, installation of generator sets, sound insulation and...
