DETAILED DESCRIPTION

[0061] Identical or substantially functionally identical or similar elements are denoted in the figures by the same reference designations.

[0062] FIG. 1 shows a wind power installation 100 having a tower 102 and a nacelle 104. A rotor 106 with three rotor blades 108 and with a spinner 110 is arranged on the nacelle 104. The rotor 106 is, during operation, set in rotational motion by the wind, and thus drives a generator in the nacelle 104.

[0063] In the interior of the tower 102, preferably even already during the erection of the tower 102, there is arranged a supply scaffold 1 illustrated in FIGS. 2-12.

[0064] FIGS. 2-10 illustrate a first exemplary embodiment of a supply scaffold 1. FIGS. 11-12 illustrate a further exemplary embodiment of a supply scaffold 1, which differs from the supply scaffold 1 illustrated in FIGS. 2-10 substantially by a different elevator module. Unless stated otherwise, the following statements apply to both variants of the supply scaffold 1.

[0065] The supply scaffold 1 comprises multiple scaffold modules 200 which are arranged one above the other and connected to one another. The scaffold modules each have four corner struts 210 and transverse struts 211 which connect the corner struts 210 at the upper and lower end. As can be seen in the figures, the scaffold modules 200 have a framework-like lattice structure.

[0066] The first, lower scaffold module is in the form of a base module, which is arranged so as to stand on a floor. The further scaffold modules are in the form of core modules, and are arranged on the floor module, likewise in a standing manner.

[0067] The scaffold modules 200, in particular the base module and/or the core modules, have a substantially cuboidal basic shape with a longitudinal extent and/or longitudinal axis oriented substantially vertically in the operational state.

[0068] First fastening elements 260, which in this case are arranged on the corner struts 210, serve for fastening the supply scaffold 1 (at least partially inter alia) in a horizontal direction, for example to a tower interior wall, and serve preferably merely for positional stabilization in a substantially horizontal direction.

[0069] The scaffold modules 200 may be in the form of an open scaffold module 201 or as a closed scaffold module 202. In the exemplary embodiments illustrated, the open scaffold modules 201 have one fully open sidewall 230o. In the case of the closed scaffold modules 202, that sidewall 230g which in the case of the open scaffold modules 201 is of open form has a centrally arranged transverse strut 231, and is thus closed. As can be seen in FIGS. 11 and 12, the open sidewall 230o serves in particular for boarding and disembarking from an elevator module.

[0070] The elevator module 400 illustrated in the exemplary embodiment of FIGS. 2-10 has a riser element in the form of a toothed wheel 401, which in the operational state engages with a riser device arranged on the rear sidewall 240, which riser device is in this case in the form of a toothed rack 402. By means of a drive action, preferably of the toothed wheel 401, it is thus possible to realize a substantially vertical movement of the elevator module 400 in order to convey persons and/or loads in the interior of the supply scaffold 1. The drive of the toothed wheel 401 may preferably be arranged on the elevator module 400.

[0071] The elevator module 400 illustrated in FIGS. 11 and 12 serves substantially the same purpose as the elevator module 400 illustrated in FIGS. 2-10. FIG. 11 illustrates the elevator module 400 in two different positions (at the lower end and at the upper end of the supply scaffold 1). The elevator module 400 also preferably has a riser element (not illustrated) which engages with a riser device (not illustrated) in order to realize the substantially vertical movement of the elevator module 400.

[0072] The two narrow sidewalls 220 have a framework-like lattice structure both in the open embodiment and in the closed embodiment of the scaffold modules 200. Second fastening elements 270 arranged on the narrow sidewalls 220 serve for receiving cable arrangements 300. The function and design of the narrow sidewalls 220 and of the wide sidewalls 230o, 230g, 240 may also be interchanged, that is to say a wide sidewall may serve for the arrangement of cable arrangements, whereas one of the narrow sidewalls may be in the form of a ladder and the other narrow sidewall may be of open or closed form. Further corresponding variations are possible.

[0073] The rear wide sidewall 240 likewise has a framework-like lattice structure both in the open and in the closed embodiment of the scaffold modules 200, but said structure has transverse struts 241 which have a rung spacing in a substantially vertical direction, which are suitable and/or approved for the use of the sidewall 240 as a ladder. The rungs 241 are divided centrally by a climbing aid 250, which may be formed for example from two C shaped profiles.

[0074] In the operational state, the supply scaffold 1 is arranged with a first scaffold module, which is in the form of a floor module, standing on a floor. In FIGS. 3 and 10, the supply scaffold 1 is arranged on a floor of a tower foot 103. In FIG. 4, an electrical module is firstly arranged on a tower foot 103, which electrical module forms the floor on which the supply scaffold 1 is arranged.

[0075] In FIG. 10, a platform 500 with a floor 501 and a railing 502 is arranged in an encircling fashion on the outer side of the supply scaffold 1, which platform may serve for accommodating persons and/or for the temporary storage of working means and/or tools. The platform 500 is preferably displaceable in a substantially vertical direction along the supply scaffold 1, such that the platform 500 can be utilized at varying heights. It is furthermore preferable for a substantially horizontal extent of the platform 500 to be variable, such that the platform 500 can be adapted to varying inner diameters of a tower, for example in the case of towers which taper in an upward direction.

[0076] The supply scaffold 1 has the advantage in particular that, owing to the standing arrangement of the scaffold modules on a floor of a tower, the supply scaffold 1 is already operationally ready even when the tower has not yet been erected to its full height. In this way, the supply scaffold 1 can be utilized already during the erection of the tower, in particular a sidewall 240 in the form of a ladder and/or an elevator module 400, 400 and/or a platform 500. This can considerably reduce the need for an external crane and/or external lifting platforms already during the erection of the tower, or even render the use of such external lifting means entirely or partially superfluous. Furthermore, the compact and space-saving arrangement of the supply scaffold with supply elements in the interior of the tower permits a simpler and cost-saving arrangement of other tower interior fixtures, in particular on the tower interior wall, and/or of external tensioning cables.
