新型风电风机轮毂安装用支承装置OA

The traditional fan is installed from the foundation,with components hoisted from bottom to top in turn.In addition,in installation,the fan blades needs to be hoisted at high altitude for three times,so the crane operation lasts too long.Especially in special environment,this increases the safety risk of operation,and aerial work also increases the difficulty of blade and hub docking.Currently,under the premise that the hoisting capacity of large cranes meets the requirements,three blades can be installed on the hub on the ground and then hoisted at one time,which can realize the grounding of aerial works.However,the existing ground support device can't rotate and can only be adjusted by crane,and the flange bolt installation operation space is insufficient,which is inconvenient for construction,and the same support can only be used in the installation of one kind of hubs.Therefore,in this paper,a new type of support device for wind power fan hub installation is introduced,which solves the shortcomings of traditional fans,and has simple structure and high efficiency.
