Description
Technical Field
The invention relates to the technical field of wind power generation equipment, in particular to an integrated transmission system assembly precision control device and a method thereof.
Background
With the rise of renewable energy sources and concerns about carbon emissions, offshore wind power generation has received widespread attention as an important component of clean energy. The gearbox of an offshore wind turbine is a core component for converting wind energy into electrical energy, but is also one of the components most susceptible to high loads and severe marine environments. Accordingly, the design and assembly of gearboxes becomes critical, and continued improvements are needed to improve performance, reliability, and reduce maintenance costs.
Conventional gearbox supports typically employ rigid brackets that secure the gearbox to the blower housing, however, such rigid brackets have limitations in facing the vibration, load and wind load of the offshore wind turbine. In recent years, elastic support systems for gearboxes have been attracting attention, which utilize elastic elements, such as springs or shock absorbers, to relieve vibration and impact loads to which the gearboxes are subjected, improving the reliability and performance of the gearboxes.
However, this design presents problems in terms of accuracy control of the fan assembly process. For example, when the two-point support type offshore wind turbine is assembled in an assembly workshop, the torque arm of the gearbox is installed and fixed on the frame by means of the upper and lower liquid compound springs which are elastically supported, and after the wind turbine is hung on the whole machine hoisting site, the gearbox is slightly tilted upwards due to the gravity action of the wind turbine of the transmission system, and the upper liquid compound spring can be further compressed. This reduces the positioning accuracy of the gearbox in the fan drive train, affecting its life and performance.
At present, the existing wind turbine generator torque arm displacement detection device and elastic failure assessment method utilize a displacement sensor to detect the displacement of a torque arm of a gear box, calculate the rigidity of an elastic support through a displacement variation value, and carry out failure assessment of the elastic support based on the displacement variation value. However, this patent uses only the displacement sensor for failure evaluation of the elastic support, and does not consider that the sensor can also monitor the state during the assembly of the gearbox and use the displacement data as a reference for improvement of the assembly process of the gearbox.
In summary, how to effectively solve the problems that the assembly accuracy and reliability of the gear box cannot be effectively improved is a problem that needs to be solved by those skilled in the art.

According to the technical requirement of fan gear box assembly, setting relevant judging standards, and judging whether the gear box assembly accuracy meets the technical requirement after the fan is lifted up the wind wheel according to the displacement change. If the assembly accuracy meets the requirement, the adjustment is not performed.
