Description

Technical Field

[0002] With the deepening of sustainable development, wind power generation has ushered in better development, but how to save the hoisting cost accordingly while ensuring the efficiency of wind turbine hoisting has become a difficult problem that needs to be broken through.

[0003] In the related art, the general steps for installing a wind turbine generator set are: a transport vehicle first transports the wind turbine components (for example, the tower and the impeller) to the installation site, and then a lifting device is used to lift the tower. At this time, another lifting device is required to tow the tower. When the tower is adjusted from a horizontal state to a vertical state, the vertical tower is lifted to the installation position. After the tower is lifted, the lifting tools on the lifting device are replaced, the impeller is lifted, and finally the impeller is lifted to the impeller installation position.

[0004] The above-mentioned related technologies have the following technical defects when hoisting wind turbines: first, multiple hoisting equipment is required, which on the one hand increases the hoisting cost of the wind turbine, and on the other hand, when the installation space of the wind turbine is limited, it makes the hoisting of the wind turbine inconvenient; second, after the tower is hoisted and the hoisting equipment is replaced, the impeller is hoisted again, which increases the hoisting process of the wind turbine, thereby greatly reducing the hoisting efficiency of the wind turbine. Summary of the invention

[0005] In order to reduce the cost of hoisting a wind turbine and improve the efficiency of hoisting a wind turbine, the present application provides a wind turbine hoisting device.

[0006] The present application provides a wind turbine hoisting device, which adopts the following technical solution:

[0008] By adopting the above technical solution, when installing a wind turbine, first fix a tower vertically at the installation position, repeat the above steps, connect and fix multiple towers in sequence, and when multiple towers are fixed and connected, install the cabin on the tower. After the cabin is installed, move the impeller to the installation hole position, and fix the impeller to the cabin, so as to achieve the installation of the wind turbine. When it is necessary to hoist the tower, adjust the hoisting device to the first state, the hoisting assembly drives the lifting frame to move, and the lifting frame drives the flip unit to move to the tower flipping position (the gap between the tower and its transport vehicle). After the staff adjusts the flip unit to a reasonable position, the flip plate position is flipped. Directly below the tower, turn on the power assembly, which drives the flip plate to move. The movement of the flip plate drives the tower above it to move. At the same time, flip the clamping plate, and the clamping plate flips to the end of the tower.
