The invention relates to a system for assembling a wind turbine without using cranes, which has lifting systems (8) arranged peripherally to the tower (3), with a lifting platform (11), a base (10) and an internal lifting mechanism. The lifting platform (11) engages with different coupling tools (16, 18 and 2x) that can be supported on an auxiliary column (15) and thereby raise or lower the consecutive modules of the tower (3). The assembly method consists of: preparing the foundation (5) on the floor (6) or on the offshore platform, installing the basic module (7), arranging the lifting systems (8) peripherally. In the case of an offshore wind turbine, the underwater section is assembled and after opening a hole in the platform the lifting system itself will enable said underwater section to be immersed until it reaches the bottom. Once said section is attached, the gondola (4) is attached and raised, the upper module (14) of the tower is placed in the gap created, the lifting platforms (11) are lowered, the auxiliary column (15) and the connection flange (16) are installed, the gondola (4) is raised with the top module of the tower (14), the module (17) is placed in the gap created, the auxiliary column (15) is disconnected and the lifting platforms (11) are lowered, the auxiliary column (15) and the connecting piece (18) are installed, the gondola (4) is lifted with the module (14) and the module (17). The above process is repeated using the other modules until the end of the assembly. |
