Method and device for aligning tower sections

摘要

The present invention generally relates to a hollow structural part (2) configured to form part of a wind turbine (1), said structural part (2) having a first end (2′) and a second end, with an inwardly directed annular flange (70) at said first end (2′), said flange (70) having a plurality of holes (72), at least one alignment device (10) being mounted to said hollow structural part (2), a first connector (22) being connected with said structural part (2) to connect said alignment device (10) to said structural part (2), said alignment device (10) having a guide portion (35) with a protracted guiding surface part (38) extending in the general direction away from said opposite second end and towards a centre line (CL) of said hollow structural part (2), said guiding surface part (38) being for directional guiding of another structural part (5) of said wind turbine (1) during assembly thereof, an elongated bar (40) connected with said guide portion (35), said bar (40) having a portion extending from said bottom face (71) of said flange and into one of said holes (72) of said flange, with an end of said bar (40) located within said hole (72), wherein forces on said guide portion (35) are at least in part balanced by lateral forces acting on said portion of said bar (40).

主权项

1. An alignment device for flange-to-flange alignment of two structural parts of a wind turbine, comprising:
a first connector configured for being connected with a first one of the two structural parts to secure said alignment device to the first one of the two structural parts; a guide portion with a protracted guiding surface part for directional guiding of a second one of the two structural parts during said alignment; and a bar rigidly connected with said guide portion, said guiding surface part diverging away from said bar, said bar being capable of assuming different positions by tilting, relative to said first connector.
