Wind power generation main shaft turnover device

Abstract

The invention discloses a wind power generation main shaft turnover device which comprises a base and a supporting frame, the supporting frame is in sliding connection with the base, a turnover disc is arranged on one side of the supporting frame, a supporting column is arranged at the upper end of the base, the turnover disc is hinged to the supporting column through a rotating shaft, the rotating angle of the turnover disc is 90 degrees, and a motor for driving the turnover disc is arranged on the base. A supporting hopper is arranged at the lower end of the overturning disc, and one side of the supporting hopper is connected with a bracket for fixing the main shaft. The wind power main shaft turnover device can fix a wind power main shaft and achieve repeated turnover of the main shaft, manual assistance is not needed in the turnover process, operation is easy and fast, the trouble of binding and manual adjustment is omitted, labor force is saved, the turnover process is safer, meanwhile, the wind power main shaft turnover device can serve as a wind power main shaft storage frame, and safety and stability during storage of the main shaft are guaranteed.

Description

technical field [0001] The invention relates to the technical field of the production of main shafts of power generation, in particular to a device for turning over a main shaft of wind power generation. Background technique [0002] Wind power refers to converting the kinetic energy of wind into electrical energy. Wind energy is a kind of clean and pollution-free renewable energy energy, which converts the kinetic energy of wind into mechanical kinetic energy, and then converts mechanical energy into electrical kinetic energy, which is wind power generation. The principle of wind power generation is to use the wind to drive the blades of the windmill to rotate, and then increase the speed of rotation through the speed increaser to promote the generator to generate electricity. [0003] The wind power main shaft is one of the components of the wind power transmission system. During the production process of the wind power main shaft, the main shaft and different parts need ...

AI Technical Summary

Problems solved by technology

[0003] The wind power main shaft is one of the components of the wind power transmission system. In the production process of the wind power main shaft, the main shaft and different components need to be changed vertically and horizontally for many times during the assembly process. Currently, the main shaft is turned over by using During the hoisting, the main shaft is bound and fixed by the sling and the hook to be lifted and turned over. During the hoisting process, the staff needs to support the main shaft to control the angle, which is not only cumbersome to operate but also has great potential safety hazards.
