Problems solved by technology

Offshore wind power towers are generally prefabricated in a site close to the wharf. After prefabrication, they can be shipped as a whole for offshore installation. This can overcome the limitations of transportation conditions and the tower can be prefabricated as a whole. However, due to the large diameter and thin wall of the tower, The overall length is large, and deformation is more likely to occur during hoisting

Abstract

The invention provides an offshore wind powder tower hoisting appliance comprising a main hoisting plate, reinforcing plates and a flange contact plate, wherein the main hoisting plate is fixed at one side of the flange contact plate far from a power tower, the bottom ends of the reinforcing plates are fixed on the flange contact plate and one side of each reinforcing plate is fixed with the main hoisting plate; the main hoisting plate is provided with a main hoisting hole, and a plurality to bolt holes are arranged on the flange contact plate. The hoisting appliance is hoisted after being connected with tower flanges by connecting the bolts, thereby effectively avoiding the deformation and the damage of the tower, has better commonality, safe and convenient operation and convenient disassembly and can be used repeatedly and reduce the construction cost.

Description

technical field [0001] The invention relates to an installation appliance, in particular to an offshore wind power generation tower hoisting appliance. Background technique [0002] The development of new energy is the need for the sustainable development of my country's economy and society, and wind power technology is relatively mature in new energy and suitable for large-scale development. At present, the development of domestic wind power technology is limited to land, and the field of offshore wind power technology has just started. get started. [0003] Regardless of whether it is a wind power project set up on land or offshore, the prefabrication and installation of the tower as the foundation of the wind turbine and the impeller are the most critical technologies, especially the risk of tower hoisting. [0004] The tower is a cone, the maximum diameter of the bottom is 3976mm, the smallest part of the upper end is more than 2 meters, and the height is close to 40 met...
