Wind turbine elevator for hoisting a naecelle along a tower and pivoting the naecelle at a top of the tower

摘要

A method for assembling a wind turbine includes: unloading a nacelle and hub from a truck; connecting the nacelle and hub to a carriage of an elevator in a vertical position; connecting blades to the hub, thereby forming a rotor; raising the carriage, nacelle, and rotor along a tower to a top of the tower; and pivoting the carriage, nacelle, and rotor to a horizontal position at the top of the tower.

主权项

1. An elevator for a wind turbine, comprising:
a tower having a base, a body, and a guide rail extending along the tower body; a carriage movable along the guide rail and having a bearing and rotary drive for receiving a nacelle in a vertical position; a drive system for raising the carriage and nacelle along the guide rail; and a pivot system for engaging the carriage when the carriage and nacelle arrive at the top of the tower, wherein:
the drive system comprises:
a motor connected to the carriage;a pinion connected to a rotor of the motor; anda rack extending along the guide rail, andthe pivot system comprises:
a sensor or switch for detecting arrival of the carriage and nacelle at the tower top;a fastener for pivotally connecting the carriage to the tower; anda fastener actuator for engaging the fastener with the carriage in response to the detected arrival.
