Problems solved by technology

[0003] Existing wind turbine nacelles are generally made of fiberglass products, which are bulky, flexible, special materials, and easy to deform. The nacelle is divided into multiple parts. Assemble on the main engine, and then adjust the coaxiality of the nacelle cover tower flange and the yaw bearing as a whole, and the coaxiality of the main shaft seal brush ring and the main shaft, and ensure that the two coaxialities operate within the required range at the same time It is very difficult, often after the coaxiality between the main shaft seal brush ring and the main shaft is adjusted, the coaxiality between the tower flange and the yaw bearing will change, and the coaxiality between the tower flange and the yaw bearing After the guarantee, the coaxiality of the main shaft seal brush ring and the main shaft does not meet the requirements, so it is difficult to guarantee the two coaxialities at the same time, the requirements for manpower and material resources are also high, and the assembly time is very long

Embodiment Construction

[0023] The present invention is described in detail below in conjunction with the accompanying drawings:

[0024] like Figure 1-Figure 2 As shown, the present invention includes a movable frame 1, a fixed frame 2, a connecting bolt 3, and a fastening bolt 4. The movable frame 1 is arranged on the fixing frame 2, and the fixing frame 2 is provided with fastening bolts 4. The movable frame 1 is movably connected to the fixed frame 2 through connecting bolts 3 .

[0025] The movable frame 1 includes a horizontal board and a vertical board, and the horizontal board and the vertical board form an inverted T-shaped board. The fixing frame 2 includes a rectangular plate, four legs are arranged under the rectangular plate, and the fastening bolts 4 are arranged on the four legs. The horizontal plate of the movable frame 1 is provided with a first groove, the rectangular plate of the fixed frame 2 is provided with a second groove corresponding to the position of the first groove, an...

Abstract

The invention specifically discloses a large wind turbine generator set cabin cover positioning tool and a method for adjusting coaxiality. The positioning tool comprises a moving frame, a fixed frame, a connecting bolt and a fastening bolt, wherein the moving frame is erected on the fixed frame, the fastening bolt is arranged on the fixed frame, and the moving frame is connected with the fixed frame through the connecting bolt. The large wind turbine generator set cabin cover positioning tool and the method for adjusting coaxiality have the advantages that time is greatly saved by means of a novel assembling mode, and the labor intensity is reduced.

Description

[0001] technical field [0002] The invention relates to a large wind turbine nacelle cover positioning tool and a method for adjusting coaxiality using the device, which are used in the process of nacelle cover assembly and coaxiality adjustment in the field of wind power technology. Background technique [0003] The existing wind turbine nacelle covers are generally made of glass fiber reinforced plastics, which are large in size, flexible, special materials, and easy to deform. The nacelle cover is divided into multiple parts. The original nacelle cover assembly scheme Assemble on the main engine, and then adjust the coaxiality of the nacelle cover tower flange and the yaw bearing as well as the coaxiality of the main shaft sealing brush ring and the main shaft, and at the same time ensure that these two coaxiality operate within the required range It is very difficult, often after the coaxiality of the main shaft seal brush ring and the main shaft is adjusted, the coaxia...
