Embodiment Construction
[0033] Combine below figure 1 and figure 2 , the present invention is further described:
[0034] The tower self-elevating crane 6 includes a lifting system, a self-elevating system, a fixing system, a machine platform 62, a balance beam spreader 67, a tower spreader 68, special fixtures for blades, a hydraulic system, a power supply system, a control system, and an operating system .
[0035] Specifically:
[0036] 1.1. Lifting system.
[0037] The lifting system is mainly composed of jib, luffing cylinder, hydraulic winch, wire rope-pulley block and base. There are two sets in total, which are symmetrically arranged on both sides of the machine platform. They can be operated in conjunction or independently.
[0038] 1.1.1. Boom.
[0039] The jib can be a two-section telescopic box or fixed-length truss jib. The structural form of the two-section telescopic jib has the advantages of compact structure and beautiful appearance, and the fixed-length truss jib has the adva...

The invention relates to a separated hoisting device of an offshore wind turbine generator, and an installation method. The separated hoisting device comprises an offshore wind power foundation platform, a transfer platform, a plurality of combinable tower cylinders, an engine room, a wheel hub, blades, a tower cylinder self-lifting crane and a floating crane boat, wherein the offshore wind power foundation platform is provided with a base tower cylinder; the floating crane boat can be loaded with the plurality of combinable tower cylinders, the transfer platform, the engine room, the wheel hub, the blades and the tower cylinder self-lifting crane and is installed on the offshore wind power foundation platform by a floating crane; the transfer platform is arranged between the offshore wind power foundation platform and the floating crane boat and used for transferring and placing mounting components; the tower cylinder self-lifting crane is used for connecting the plurality of combinable tower cylinders to the base tower cylinder and vertically moves along the mounted tower cylinders; the engine room, the wheel hub and the blades are also mounted on the tops of the combined tower cylinders by hoisting of the tower cylinder self-lifting crane.
Description
technical field [0001] The invention relates to a wind turbine component hoisting device and an installation method, in particular to an offshore wind turbine component hoisting device and an installation method. Background technique [0002] The hoisting method of the wind turbine refers to the hoisting method of the unit components, which is divided into two types: split hoisting method and integral hoisting method. Onshore wind farms usually have good operating site conditions, and at this stage, large crawler cranes or large truck cranes are basically used for separate hoisting. Offshore wind farms are limited by sea climate, tides, waves, water depth, seabed geology and other conditions. Compared with the hoisting of onshore wind turbines, the situation is much more complicated. Compared with the hoisting of onshore wind turbines, the hoisting of offshore wind turbines lacks a stable hoisting platform. The lifting equipment installed on the ship is easy to shake due to...
