the fiber cable transmission system in the step (8): taking 32R-shaped steel bar ring pulling plates (127), and respectively fixing the R-shaped steel bar ring pulling plates on the annular mass block (111) and the bottom of the laminated wooden tower tube (4) through screws and gaskets (128) so as to connect the fiber cables (126) with the end parts of two members; taking 16 fiber cables (125), and respectively penetrating two ends of each fiber cable through an R-shaped steel bar tab plate (113) fixed on the annular mass block (111) and an R-shaped steel bar tab plate (127) at the bottom of the laminated wooden tower tube (4) to enable the annular mass block (111) and the laminated wooden tower tube (4) to be integrated; in addition, the fiber cable (126) is tightly attached to the fixed pulley groove, so that the fiber cable is prevented from falling off in the lifting process;
a buffer device (13) in the step (9): the number of the bottom arc-shaped buffer supports (131) is 8, the bottom arc-shaped buffer supports are pre-embedded at reasonable positions on the inner wall of the concrete tower barrel (9) in advance, and then the connecting pieces (4), (133) are fixed at the connecting positions of the concrete tower barrel (9) and the bottom arc-shaped buffer supports (131) through gaskets (134) and screws (135), so that the reliability of connection is enhanced; the number of the annular rubber cushion blocks (131) is 1, and the annular rubber cushion blocks are fixed on the bottom arc-shaped buffer support (131) through epoxy resin glue;
step (10), integral assembly: and (5) after the used epoxy resin adhesive reaches the standard strength, mounting the components connected in the steps (1) to (9) at the appointed position, and hoisting the engine room, the hub and the blades to complete the integral installation.
