Definitions

  • the present disclosure relates to elevator systems, for example service elevator systems.
  • the elevator systems may be configured for use in wind turbine towers.
  • the present disclosure further relates to wind turbines comprising such elevator systems.
  • Wind turbines are commonly used to supply electricity into the electrical grid.
  • Wind turbines generally comprise a rotor with a rotor hub and a plurality of blades.
  • the rotor is set into rotation under the influence of the wind on the blades.
  • the rotation of the rotor shaft drives the generator rotor either directly (“directly driven”) or through the use of a gearbox.
  • the operation of the generator produces the electricity to be supplied into the electrical grid.
  • hoists are often used in the form of elevator-like structures where a lift platform or a cabin for the transportation of people and/or equipment is hoisted up or down within the wind turbine tower.
  • Wind turbines are often provided with working platforms arranged at various heights along the height of the tower with the purpose of allowing workers to leave the cabin and inspect or repair equipment where intended.
  • These sorts of elevator systems are also known in other applications, such as e.g. factories, construction sites, and all sorts of towers.
  • Elevator systems in general include an elevator car being suspended within a hoistway by ropes, cables or belts.
  • a counterweight may be provided, depending on e.g. the available space.
  • Other systems such as hydraulic elevators normally do not comprise a counterweight.
  • elevator systems include a moving or travelling cable for supplying electric power to the elevator cabin and/or for signal communication between components associated with the elevator car/cabin and a control panel provided in a fixed location relative to the hoistway. The control panel may be provided at any height up in the hoistway.
  • an intermediate travelling cable fixation point may be chosen, most frequently at a height which is halfway up in the hoistway. Therefore, when the elevator car is below this height, the travelling cable is thus suspended downwards. And when the elevator car is above this height, the travelling cable is thus carried upwards.
  • a travelling cable may begin to move and sway within an elevator hoistway or the cable can become tangled up in itself. This is most prominent in high slender structures, such as e.g. tower of larger (MW class) wind turbines, in which the tower may move significantly.
  • MW class MW class
  • elevator ropes and cables which may include hoist ropes, compensation ropes, governor ropes, and travelling cables, may also vibrate in harmony with the wind induced sway of the structure and other dynamic factors affecting the structure.
  • loads such as for example aerodynamic forces associated with the wind, rotor rotation, etc. may act on the structure.
  • These loads may further be increased in offshore wind turbines by the forces exerted by waves, currents and tides. It is thus desirable that elevator cabins arranged inside wind turbine towers run controlled by lines, cables or any other rigid guiding element extending all the way from the top to the bottom of the wind turbine tower.
  • the aforementioned loads can produce vibrations and sway of the ropes and cables which may cause fatigue and wear, excessive noise, and the increased possibility of tangling thus potentially shortening the lifetime of the cables and complicating normal operation of the elevator system.
  • Document JP6278968 describes a moving cable stabilizer for an elevator comprising a guide member installed in a vertical direction between the elevator car and an internal surface of the hoistway, a feed roller support, a support arm attached to the roller support and slidably attached to the guide member and two or more feed rollers arranged in parallel in an axial direction and rotatably attached to the feed roller support.
  • a guide member installed in a vertical direction between the elevator car and an internal surface of the hoistway
  • a feed roller support a support arm attached to the roller support and slidably attached to the guide member and two or more feed rollers arranged in parallel in an axial direction and rotatably attached to the feed roller support.
  • an elevator system comprising an elevator cabin guided by a pair of taut cables running laterally from the elevator cabin, a travelling cable for supplying energy to the elevator cabin, and a pulley mounted on a pulley frame.
  • the pulley with the pulley frame is movably suspended on the travelling cable and the system further comprises one or more transverse elements each having one end attached to the pulley frame and the other end adapted to be slidably arranged with respect to one or more of the taut cables.
  • the travelling cable in use, i.e. when the elevator cabin goes up and down, the travelling cable is carried upwards and downwards. Since the pulley and the pulley frame are movably suspended from the travelling cable, in use, the pulley with the pulley frame can self-travel along the travelling cable. Such a motion of the pulley and pulley frame on the travelling cable straightens the travelling cable at all possible positions. Furthermore, the provision of a transverse element having one end attached to the pulley frame and the other end slidably arranged with respect to one or more of the rigid guiding elements together with the motion of the pulley frame along the travelling cable entails a slide of the transverse element along such rigid guiding elements.
  • the transverse elements thus act as a spacer between the pulley frame which slides on the travelling cable and the rigid guiding elements. This can substantially stabilize the travelling cable's position even when loads producing vibrations and sway of the cables are acting. Tangling up of the travelling cable in itself can also thus be avoided or substantially reduced with the provision of such spacers, i.e. transverse elements.
  • the travelling cable is thus subjected to less stress therefore extending its lifetime.
  • transverse elements which are already present in the system are used. No additional guiding elements are necessary.
  • transverse elements substantially as hereinbefore described is quite simple to implement. It can therefore be easily retrofit into existing elevator installations having travelling cables with a pulley suspended from the travelling cable. Moreover, it is a solution that may be fitted in a relatively small area as it is the hoistway dimension of an elevator system.
  • pulley is to be understood as covering any form of wheel or roller that guides or redirects a cable along its circumference.
  • Pulley herein thus covers e.g. sheaves with a specific groove around its circumference between two flanges, but also any other form of cable guiding wheel.
  • a system substantially as hereinbefore described ensures that the ability of the travelling cable to move in the horizontal plane, i.e. in a plane substantially perpendicular to the up and down movement of the elevator cabin is reduced.
  • Such systems may be adapted or configured for a particular application, such as e.g. a wind turbine tower.
  • an inner surface of a hoistway of the elevator system may be provided with a rack and the elevator cabin may be provided with a pinion arranged to mesh with the rack such that the elevator cabin can be driven by the rack and pinion engagement.
  • a motor driving the pinion may be arranged inside the elevator cabin.
  • one or more traction wire ropes may be used for driving the elevator cabin.
  • the pulley frame may further be adapted to be guided along at least one traction wire rope or a safety wire rope.
  • the pulley frame may further be provided with runners arranged such that in use the runners can glide on the inner surface of a hoistway of the elevator system. This way, in use, when the pulley frame self-travels along the travelling cable it can also be guided on the inner surface of the hoistway of the elevator system by the runners and discontinuities such as the junctions between e.g. wind turbine tower's sections of such an inner surface can be easily overcame in a relatively smooth manner.
  • the end of the transverse element that is adapted to be slidably arranged with respect taut cables may be selected from the group consisting of a pair of rollers, an eyelet or a substantially C-shaped profile.
  • other ways of adapting the end of the transverse elements for being slidably arranged with respect to the taut cables may be foreseen.
  • a second aspect provides a wind turbine comprising an elevator system substantially as hereinbefore described arranged within a wind turbine tower.
  • FIG. 1 shows an elevator system according to a first embodiment.
  • the elevator system may comprise an elevator cabin 1 which may move up and down in the inside of a hoistway (not shown) driven by a traction wire rope 7.
  • a traction wire rope 7
  • more than one traction wire rope may be provided.
  • a safety wire rope 8 may further be provided.
  • the elevator cabin 1 may be guided by a pair of taut cables 2 running laterally from the elevator cabin 1.
  • the elevator cabin 1 may be provided with cable guiding means 14 that may be selected from the group consisting of a tubular part, a ring or an eyelet, a substantially C-shaped profile or similar. At least one cable guiding means 14 may be arranged at each side of the elevator cabin or two or more such means may be arranged at least in an upper and a lower location of each side of the elevator cabin.
  • the taut cables are under tension, and due to this tension they become relatively rigid and thus suitable as a cabke guiding means.
  • a travelling cable 3 may be provided for supplying energy to the elevator cabin 1.
  • the travelling cable 3 may be connected to a power supply at one end (not shown) and to the elevator cabin 1 at the other end.
  • a pulley 4 mounted on a pulley frame 5 may be arranged in a movably suspended manner on the travelling cable 3.

  • the pulley frame 5 may further be guided along the traction 7 and safety 8 wire ropes of the elevator system. In other cases, the pulley frame may be adapted to be guided along at least one of the traction and safety wire ropes.
  • Figures 4a-4d show a pulley frame adapted to be guided along at least one of traction and safety wire ropes according to an embodiment.
  • these further cables may also benefit from the increased stability of the travelling cable arrangement.
  • the two transverse arms help to reduce oscillations and movements of the travelling cable. If the travelling cable pulley is relatively fixed in space, then the corresponding portions of these further cables are also fixed in space. The movements of these further cables (for traction, safety etc.) may thus also be reduced.
