Embodiment 1

[0027] Such as Figure 1 to Figure 4 As shown, the embodiment of the present invention provides a double-blade hoisting device, which is used for hoisting the combination of the hub and the double blades. Put mechanism 10 and spreader 40. Wherein, the lifting adjustable mechanism is connected with the steel cable retracting mechanism 10 for controlling the lifting of the steel cable retracting mechanism 10 . The lifting adjustable mechanism can be the main hook on the offshore wind turbine installation ship, which can lift heavy objects and adjust the lifting of heavy objects according to the needs of actual working conditions.

[0028] Double-blade 30 hoisting equipment The spreader 40 of the double-blade hoisting equipment has a long arm 401 and a short arm 402 perpendicular to the long arm 401, and the short arm 402 is connected to the combination of the double blades of the hub, mainly used as a spreader 40 When docking with the double blades 30, the docking parts of the...

Embodiment 2

[0045] Such as image 3 and Figure 4 As shown, another aspect of the embodiment of the present invention provides a double blade hoisting method, comprising the following steps:

[0046] S1. Connect the lifting adjustable mechanism with the steel cable retractable mechanism 10, connect the steel cable retractable mechanism 10 with the spreader 40, start the lifting adjustable mechanism, and control the lifting adjustable mechanism to lift the steel cable retractable mechanism 10 and the hanger 40 that is connected with the steel cable retracting mechanism 10.

[0047] Of course, before step S1, it is necessary to disassemble the damaged single blade (manual operation), and clean the end surface of the pitch bearing of the impeller before disassembly, especially the threaded holes on the bearing. The damaged part of the blade 30 is also dismantled together.

[0048] When connecting the lifting adjustable mechanism and the steel cable retractable mechanism 10, it is only nec...

Abstract

The embodiment of the invention provides double-blade hoisting equipment and method. The equipment is used for hoisting an assembly of a hub and double blades. The hub is provided with three flange faces connected with the blades. The equipment comprises a lifting-adjustable mechanism, a steel cable take-up and pay-off mechanism and a hosting device. The lifting-adjustable mechanism is connected with the steel cable take-up and pay-off mechanism and used for controlling the steel cable take-up and pay-off mechanism to ascend and descend. The hoisting device is provided with a long arm and a short arm perpendicular to the long arm, and the short arm is connected with the assembly of the hub and the double blades. The steel cable take-up and pay-off mechanism is provided with a first reel, a second reel and a driving part. The driving part drives the first reel and the second reel to independently rotate. A steel cable connected with the long arm is wound on the first reel, and a steel cable connected with the short arm is wound on the second reel. By means of the hosting equipment, the problem that when a single blade is damaged and needs to be replaced, it is hard to dismount double blades from an engine room of a fan set and hoist the double blades to the ground can be effectively solved.

Description

technical field [0001] The invention relates to wind power generation technology, in particular to a double-blade hoisting device and method. Background technique [0002] For large-scale offshore wind turbines, when a single blade is damaged, after the damaged blade is removed, the rabbit-ear impeller with two blades fixed on the hub needs to be removed from the nacelle, and the rabbit-ear impeller is placed on the ground and replaced Put on new leaves. [0003] In the current domestic wind power blade maintenance and replacement method, when disassembling the rabbit-ear impeller, first install four lifting rings on the pitch bearing hole on the damaged side of the blade, and then use the main crane to separate the impeller from the generator, and then pass the Two independent auxiliary cranes are respectively connected to the tails of the two blades of the rabbit-ear impeller, and the rabbit-ear impeller is turned 90° to be in a horizontal state, which is convenient for p...
