Embodiment Construction
[0025] like Figure 1 to Figure 3 As shown, a special hoisting device includes an equipment self-elevating system 1 arranged on the equipment frame, and the self-elevating system 1 lifts the equipment itself by using the redirection pulley 19 on the wind turbine tower as a support point, During the self-lifting process of the equipment itself, the guiding and holding device 8 that moves the equipment itself close to the wind tower and moves up and down. After reaching the top dead center, the alignment device 6 and the fixing device that align and fix the equipment itself, also include The door frame 2 that is arranged on the frame and the hoisting device 4 that is installed on the door frame 2 tops.
[0026] The alignment of the alignment device 6 is completed by adjusting the luffing system 3, and the fixation of the fixing device 18 is connected with the tower by extending the outrigger through the outrigger threading device.
[0027] The mast 2 is connected with the luffi...

The invention discloses a novel hoisting construction method and a special hoisting device, in particular to a novel hoisting construction method and a special hoisting device which are suitable for the installation and disassembly of the upper equipment of the wind turbine after the tower is installed. The technical problem to be solved is that the hoisting equipment used in the traditional whole machine hoisting and dismantling construction method is large, the cost is high, the cycle is long, and the safety is poor. The invention includes a self-elevating system for the equipment. The self-elevating system uses the reversing pulley on the wind turbine tower as a support point to lift the equipment itself. Device, after reaching the top dead center, the alignment device and fixing device for aligning and fixing the equipment itself, and also includes setting the mast and the lifting device installed on the upper part of the mast. The invention is not restricted by the ground environment, reduces the damage to the environment, and greatly improves the applicability, reliability and safety of the installation and maintenance of the wind turbine.
Description
technical field [0001] The invention relates to a hoisting construction method and a hoisting device, in particular to a wind power hoisting construction method and a special hoisting device. Background technique [0002] The traditional wind power hoisting construction uses large-scale hoisting equipment based on the ground. After the tower is hoisted section by section, all the components in the nacelle are assembled on the ground and hoisted to the installation position as a whole. Then, the overall hoisting wheel hub and wind leaves. During maintenance, the construction method of hoisting the entire nacelle or the wheel hub together with the wind blades as a whole is completed by large-scale lifting equipment. [0003] With the increasing capacity of wind turbines, the height of wind turbine towers, the special topography of the installation site, and the investor's requirement to speed up the installation speed as soon as possible to obtain investment income, this requ...
