Split type hoisting method for land wind turbine generator set

Abstract

The invention relates to a split type hoisting method for a land wind turbine generator set. A cabin of a 3.XMW set is divided into a cabin body and a main gear box for hoisting, so that the weight ofeach part is controlled within 80 t; and the steps of part placement, detection and the like in the hoisting process are further combined, so that split type hoisting of the wind turbine generator set is achieved, the requirement that the total weight of large single-vehicle transportation cannot exceed 100t according to the current national policy can be met, and the hoisting requirement of mainstream large cranes in the market in the prior art can also be met; and meanwhile, the hoisting frequency of a main crane is reduced, the hoisting period of the single wind turbine generator set is shortened, and the hoisting efficiency of the wind turbine generator set is improved.

Description

technical field [0001] The invention relates to the technical field of intelligent charging of a substation inspection robot, in particular to a method for integrally hoisting components of an onshore wind power generator. Background technique [0002] With the gradual advancement of the onshore wind power grid parity policy, the role of large-scale wind turbines in improving the investment income of wind farms has become increasingly prominent, and the demand for high towers and high-power units in the wind power market has also become increasingly strong. At present, 3.XMW and above units have gradually become the mainstream models in the onshore wind power market. The heaviest components of some manufacturers’ 3.XMW units have exceeded 100t, and some installation heights have exceeded 160m. ", "big" characteristics put forward higher requirements for the existing fan hoisting technology and equipment. Therefore, how to solve the installation problem of super-high, super-...

AI Technical Summary

Problems solved by technology

[0004] For double-fed units with encircling main shaft, due to the small installation gap between the main gearbox and the main frame, it is more difficult to adopt separate hoisting. Currently, the mainstream in the industry The current split hoisting method is to use the method of splitting the generator + the top cover of the nacelle cover and accessories. This method has limited weight reduction for the overall nacelle and cannot effectively reduce the overall weight of the nacelle for units of 3.XMW and above. The performance requirements are still very high, and there are many parts to be disassembled, which increases the number of hoisting times of the main crane, increases the hoisting cycle of the unit, reduces the hoisting efficiency of the unit, and is not economical. It is mostly used when the main crane is difficult to find the source. emergency
