Description

Mixed tower construction platform

Technical Field

Background

With the progress of technology and the gradual improvement of clean energy demands of people, wind power generation technology is greatly developed. Wind power generation means that wind power generation facilities are adopted to convert wind energy into electric energy, and the existing wind power generation facilities generally comprise a wind turbine tower barrel, wind blades and a generator set, and a lifter is generally installed in the wind turbine tower barrel.

With the increase of the single-machine power of the wind generating set, the height of the tower barrel is increased, and the tower barrel is usually tens of meters to hundreds of meters. The traditional wind power flexible all-steel tower cylinder technology is difficult to meet the requirements of wind generating set towers with large rigidity and large diameter. In recent years, along with popularization of assembly type concrete technology in China, the application of the segmented precast assembled type concrete tower barrel in the field of wind power generation is increasingly popular, the defects of low rigidity and small diameter of a flexible steel tower are effectively overcome, in general, the concrete tower barrel is divided into a plurality of segments in the height direction of the tower barrel, and each segment is basically formed by splicing 4 or 8 precast concrete barrel pieces on site. In the actual working process, the concrete cylinder pieces are assembled on a special assembly platform after being transported to the site to form concrete cylinder sections, and the whole section of the concrete cylinder sections are hoisted after the assembly of the concrete cylinder sections is completed; after being hoisted to a preset position, construction operators need to carry out construction operation on the connecting surfaces of the two concrete cylinder sections, so that the connection of the two concrete cylinder sections is realized, and then the concrete cylinder sections are hoisted repeatedly until the installation of the whole concrete tower cylinder is completed.

Because the tower diameter is great, so in the in-process of assembling fan tower, need build a construction platform for processing in tower inside. Because the fan tower adopts the variable diameter structure, and current construction platform structure is simpler, can't carry out suitable adjustment according to specific tower internal diameter, this means that the size of every layer of construction platform is all different, needs the individual manufacturing, and process time is long, and the cost is higher.
