A cable laying and installation method inside a tower of a large wind turbine

Abstract

The invention belongs to the field of tower construction, and particularly relates to an assembly construction method for a collector line tower. After construction preparations are completed, the following operations are carried out sequentially: hoisting the tower legs and lower tower body sections, hoisting the holding poles and assembling the tower body segment by segment, hoisting the poles together with the tower articulated booms and cross arms, and finally disassembling the holding poles. The tower body is composed of a plurality of tower body sections. During the processes of hoisting the tower legs and lower tower body sections, hoisting the holding poles, assembling the tower body segment by segment and hoisting the pole together with the tower articulated booms and the cross arms, key components from the holding poles, top pulley blocks and tower body sections are selected and marked. Targets are established for each key component, and feature extraction is performed on the captured image stream through an image processing module of a visual recognition system. The system then estimates the real-time poses of the holding poles, top pulley blocks and tower body sections, and finally outputs visualization results to assist construction personnel in adjusting construction operations.
