The tower tube self-lifting system comprises a lifting device composed of a steel cable, an upper bogie and a hydraulic cylinder, the upper bogie is fixedly installed at the top of an outer tower tube of a to-be-lifted tower tube, the hydraulic cylinder is fixedly installed on the ground outside the fixed tower tube, one end of the steel cable is fixed to a bottom flange of the to-be-lifted tower tube, and the other end of the steel cable is fixed to a bottom flange of the to-be-lifted tower tube. And the other end of the hydraulic cylinder penetrates through the top flange of the adjacent tower drum on the outer side, passes through the upper bogie and is fixed on the hydraulic cylinder. The invention further discloses a tower drum self-lifting method of the multi-section wind power tower. The hydraulic cylinders are installed on the ground, the upper bogie is used for steering the path of the steel cable, so that the steel cable can smoothly reach the ground and is not limited by aerial work any more, more choices are provided for the hydraulic cylinders, and the hydraulic cylinders are convenient to install, replace and maintain.

    本申请提出了一种多节式风电塔的塔筒自提升系统,其包括由钢索、上转向架以及液压缸组成的提升装置,上转向架固定安装在待提升塔筒的外侧塔筒的顶部,液压缸固定安装在定塔筒外部的地面,钢索一端固定在待提升塔筒的底法兰上,另一端穿过外侧相邻塔筒的顶法兰后、经上转向架后被固定在液压缸上。本申请还公开了多节式风电塔的塔筒自提升方法。本申请将液压缸安装在地面,并利用上转向架对钢索的路径进行转向,以使钢索能够顺利地到达地面,不再受制于高空作业,对液压缸具有更多的选择,并便于对液压缸的安装、更换和维护。
