This way of operating the more distant appliances mentioned above is an achievable but also very time consuming
In addition, emergency access from a distance (into the nacelle) is blocked during passage through the hatches of the nacelle shell, thus endangering the working conditions at a distance

Embodiment Construction

[0020] figure 1 It shows how the equipment to be used is arranged when the wind turbine is being serviced after being mounted on the hub 1 . The hub 1 is mounted to the main shaft 2 of the wind turbine, which protrudes from the nacelle 3 of the wind turbine. The hub 1 is provided with an external cap called hubcap 4 which, for the sake of clarity, is partially cut away in the Figures to show how the device is mounted on the hub.

[0021] The device includes a number of major components. Firstly, the first connecting piece 5 and the second connecting piece 6 are fixed to the surface 7 of the hub 1 . The remaining parts of the device are fixed to the connectors so that the whole device is fixed to the hub via the two connectors. The rest of the equipment consists of a crane 8 , a gangway 9 with a guardrail 10 , a ladder 11 leading from the nacelle 3 to the gangway 9 and a railing 12 mounted at the forefront of the hub 1 and suspended at its end from the crane 8 . A crane 8 i...

Abstract

The invention relates to a method for conducting service on a wind turbine after the wind turbine is erected and after the hub (1) of the wind turbine is mounted on the main shaft (3) of the wind turbine. The method comprises mounting of servicing equipment a crane (8) on the hub (1) of the wind turbine and lowering and hoisting wind turbine appliances from and to the hub. Thereby, it is possible to lower from and to lift to the hub, the appliances which is to be replaced or repaired without using the hatch constituting the escape way and without having to transfer the appliances through the nacelle and along the tower. The invention also relates to means (5, 6) for primarily securing the equipment to the hub of the wind turbine.

Description

technical field [0001] The invention relates to a method of servicing a wind turbine after it has been erected (erected) and after the hub of the wind turbine has been mounted on the main shaft of the wind turbine. The invention also relates to equipment for carrying out such maintenance, as well as connections and cranes forming part of this equipment. Finally, the invention relates to a wind turbine, a hub and the use of a hub. Background technique [0002] Although most appliances installed in a wind turbine last for a long time, some appliances must be replaced or repaired during the lifetime of the wind turbine. Equipment installed in the nacelle or tower of the wind turbine can be removed from or hoisted to the nacelle by a crane or other lifting device arranged on or connected to the nacelle. The frame of the tower body and nacelle is a solid structure, even large cranes can be fixed to it, and even heavy appliances can be lowered or hoisted without difficulty. How...
