Generator stator loading structure device

Abstract

Reliable connection of a generator stator and a transporter loading arm can be achieved, the weight of the generator stator is reasonably loaded on the loading part of the loading arm, and moreover the reasonable stress distribution is guaranteed and the stress concentration is avoided through automatic change with the bending deformation characteristics of the loading arm; the larger-capacity generator stators with the section size and weight level which exceed those of the prior stators can be transported in railway by the loading arm transporter, and the transportation limit bottleneck is eliminated.

Description

Technical field: [0001] The invention relates to a generator stator loading structure device. Background technique: [0002] my country's power structure is still dominated by coal power, and it will take a long time for alternative energy to take the lead. Energy conservation and emission reduction are the primary tasks proposed by the world's environmental issues for new coal power projects and renovation projects. The capacity of coal power main units is gradually increasing. Upgrading to one million grades, improving coal combustion efficiency and saving power plant land and plant investment are the advantages brought by large-capacity units. The inland transportation of millions of generator stators is a bottleneck problem; the development of nuclear power also faces the above-mentioned problems. The State Nuclear Power will adhere to the established goal and take the establishment of inland nuclear power plants as a symbol of truly absorbing and digesting the third-gene...

Problems solved by technology

[0003] Since the carrying capacity of the vehicle design is restricted by the transportation limit and the live load standard of the road and bridge, the total weight of the heavy vehicle under the existing conditions becomes the threshold, and the improvement of the carrying capacity can only be achieved by reducing the vehicle's own weight. Structure, material, manufacturing, safety Factors, driving performance and other issues need to be properly weighed; under the promotion of energy-saving and emission-reduction policy guidelines, ultra-supercritical technology continues to develop, so that the unit capacity of the generator is increasing day by day, and the previous technology is difficult to meet the transportation needs of the generator stator; The load-carrying arm transport vehicle can greatly reduce the weight of the vehicle and the transport and loading reinforcement tools to achieve the effect of increasing the carrying weight, but the loading structure scheme between the load-carrying arm and the generator is a new subject, because the generator stator is the electromagnet of the generator. There are strict restrictions on the center, the stress position and the load-bearing capacity, and the load-bearing structure and the combined deformation of the structure affect each other. If the loading structure scheme is unreasonable, it will cause damage to the generator. If it causes stress concentration on the load-bearing arm or auxiliary structure, then Will endanger transportation safety and cause accident hazards
