Definitions

  • the invention relates to a hoist attachment and a hoist for wind turbines.
  • Modern wind turbines generally have a gondola which is pivotally mounted on a tower and which carries the rotor axis of a rotor with usually three rotor blades which drive a generator. While some components that are required to operate the wind turbine are positioned in the nacelle, other components that are not necessarily in the nacelle are positioned on the bottom of the tower. Typical components positioned on the bottom of the tower are converters and transformers.
  • the components at the bottom of the tower are usually installed after the tower has been at least partially completed, which leads to limited space in which various components with generally large dimensions and high weight have to be arranged. Likewise, when replacing one of the components on the bottom of the tower of a wind turbine, there is very little space to work.
  • the cantilever arm comprises a series of vertically extending segments, with adjacent segments in a horizontal plane
  • the invention thus relates to a hoist attachment for wind power turbines with a climbing aid arranged on the inner wall of the tower of the wind turbine, the at least two brackets, which are individually attached to the climbing aid at climbing anchoring points at at least two different heights, and a vertical lifting support strut which can be attached to the brackets in an alignment parallel to the climbing aid.
  • the invention further relates to a hoist for use in wind turbines, which comprises a fastening element and an attachment element for attaching a lifting tool, wherein the fastening element and the attachment element are connected by a series of vertically extending segments, adjacent segments in a horizontal plane are pivotally connected to one another, the attachment element being freely movable and orientable in a horizontal plane with respect to the fastening element, the fastening element being attached to an inventive hoist attachment is attached.
  • the invention relates to a method for fastening the inventive hoist, which comprises the following steps: a) successively fastening at least some of the brackets to the climbing aid anchoring points with the climbing aid; b) attaching the vertical hoist support strut to the attached brackets; c) successively attaching any remaining brackets to the access aid anchoring points with the exit aid and connecting these brackets with the vertical hoist support strut; and d) attaching the hoist to the vertical hoist support
  • each wind turbine tower is equipped with a climbing aid for personnel access to the gondola.
  • the term "ascent aid” is to be interpreted broadly and cover at least ladders, stairs and guide rails for elevators. Often times, the ascent aid is a combination of a ladder and guide rails for an elevator, the elevator being the main ascent aid and the ladder is intended for elevator failures or other emergencies.
  • the anchoring points for the climbing aid which are present anyway, are sufficiently strong for a hoist in general and are thus generally suitable for attachment of the hoist can be used on it.
  • the climbing aid since the climbing aid must not or at least not be able to be removed temporarily, it is preferred to attach the hoist attachment to the anchoring points, ie in addition to the climbing aid.
  • the inventive hoist attachment achieves this by providing at least two brackets that are individually attached to individual access aid anchoring points of the access aid.
  • the climbing aid is attached to the same anchor point, e.g. B. by loosening and re-tightening a retaining screw, temporarily from one of several anchoring points, the climbing aid remains completely attached.
  • a vertical hoist support strut is attached to it in an alignment parallel to the climbing aid. The vertical extent of the vertical hoist is testimony to most known He, especially boom arms, required.
  • the brackets are fastened to at least two different heights, which means that the vertical strut is supported at at least two points that are distant from one another, thereby absorbing moments that occur when actually using a hoist connected to the hoist attachment is supported.
  • the hoist attachment comprises four brackets. These brackets can preferably be L-shaped and / or be fastened to two different heights. It has been found that such a configuration of the hoist fastening is of great advantage with regard to the usability and strength. Due to the four L-shaped brackets, the vertical hoist support strut can have a fairly simple construction, which leads to a portable weight of the individual components, and at the same time the brackets can be installed individually before the vertical strut is attached to them, which allows easy fastening becomes.
  • the vertical hoist support strut is preferably attachable to the holding stanchions by perpendicular to the longitudinal axis of the strut. The fact that the connecting bolts run perpendicular to the longitudinal axis - ie vertical axis - of the strut ensures the best use of the load capacity of the bolts.
  • the inventive hoist to facilitate handling of a component in a confined and closed space comprises an inventive hoist attachment to which it is attached by its fastener.
  • the fastener there are a number of segments, which in turn are pivotally connected to each other, similar to a link chain that leads to an add-on element. Due to the link chain configuration, the degree of freedom between adjacent segments and thus for the entire connection between the fastening element and the add-on element is limited to the horizontal plane. In order to withstand the weight of the component attached to the attachment element either directly or via a lifting tool, the segments extend vertically, so that the row of segments provides sufficient rigidity in a vertical direction.
  • the attachment element can generally be freely moved and aligned in a horizontal plane with respect to the fastening element, as long as the distance between the two elements is less than the length of the series of segments.
  • the segments are generally tubular with connec tion elements on opposite sides of the outer circumference for pivotally connected adjacent Seg elements. This allows the segments to have a suitable horizontal extent with the required rigidity, while at the same time being light.
  • the segments preferably each comprise at least one, preferably at least two coaxial pivots, which point in the same direction, and a corresponding number of bushings with an open end for receiving the pivots of an adjacent segment as connecting elements.
  • the pivots of a segment can be used to Bil dung a pivot connection usammen sculpture Z with the implementation of the adjacent segment. Due to the con struction of the swivel connection, the row of segments can be easily disassembled by lifting a segment or a group of segments to pull the pivot pin of a swivel connection out of the corresponding bushings. This allows easy assembly, easy dismantling and easy transport of the hoist. In this case, assembly and disassembly can even be carried out without tools.
  • the first segment of the series of segments is pivotally connected to the fastening element and / or the last segment of the series of segments is pivotally connected to the attachment element. If this is the case, the one or two connections also contribute to the mobility of the entire hoist. It is preferred that the one or two connections be arranged similarly to the pivot connections between two adjacent segments of the series of segments, i. H. the fastening element and / or the attachment element can be configured to cooperate with the connecting elements of the first and / or the last segment in such a way as to provide the pivot connection.
  • the fastening element can comprise bushings for the pivots of the first segment to be inserted, while the attachment element can include pivots to be inserted into the bushing of the last segment.
  • the add-on element can encompass a cylindrical region which is to be introduced into a tubular part of the last segment.
  • the cylindrical region of the add-on element is inserted into the tubular part of the last segment, which is provided anyway in the case of a generally tubular shape of the segments. Due to the generally circular interaction surface, the attachment element can be rotated even in the last segment.
  • the add-on element is adjustable in height. This can be achieved, for example, by a swivel mechanism for a cantilever arm with a horizontal swivel axis or a vertical linear guide. If the add-on element has a cylindrical region that is to be inserted into a tubular part of the last segment, the height adjustment can be made by restricting the insertion depth, i. H. by means of blocking elements.
  • the relative position of two adjacent segments can be determined selectively. By determining the relative position of all adjacent segments and between the first and / or last segment and the fastening and / or attachment element, the relative position between the attachment element and the attachment element can be temporarily determined.
  • Different options for e.g. B. intermittent prevention of a pivoting movement of a pivot in a bushing are known and can be easily applied to the inventive hoist.

  • a hand lifting device in particular a pulley
  • adjacent segments can be detached from one another without tools.
