Abstract

Provided is a platform positioning system including a platform and an elevator, wherein a cabin of the elevator is movable along a wall segment of a building, wherein the platform positioning system further includes a first attachment mechanism for releasably attaching the platform to the cabin, wherein the motion of the cabin and the platform are coupled to each other when the platform is attached to the cabin, and a second attachment mechanism for releasably attaching the platform to the wall segment.

First claim

1 . A platform positioning system comprising:
a platform; an elevator, wherein a cabin of the elevator is movable along a wall segment of a building; a first attachment means for releasably attaching the platform to the cabin, wherein a motion of the cabin and the platform are coupled to each other when the platform is attached to the cabin; and a second attachment means for releasably attaching the platform to the wall segment.

2 . The platform positioning system according to claim 1 , wherein the building is a tower and the platform is a working platform located within the tower of a wind turbine.

3 . The platform positioning system according to claim 1 , wherein a connection provided by the first attachment means and/or the second attachment means is a pin connection.

4 . The platform positioning system according to claim 3 , wherein the first attachment means and/or the second attachment means comprises an automatically retractable pin, wherein the automatically retractable pin is located at the platform.

5 . The platform positioning system according to claim 1 , wherein the first attachment means is configured to attach the platform on at least one side wall of the cabin, and/or to a top section and/or a bottom section of the cabin.

6 . The platform positioning system according to claim 1 , wherein the platform comprises an opening through which the cabin is movable, wherein the opening is a through hole or a lateral recess.

7 . The platform positioning system according to claim 1 , wherein the platform positioning system comprises a control unit, wherein the control unit is configured to switch the platform positioning system between a first operational state, wherein the platform and the wall segment are disconnected and the platform is attached to the cabin, and a second operational state, wherein the platform and the cabin are disconnected and the platform is attached to the wall segment.

8 . The platform positioning system according to claim 7 , wherein the control unit is configured to switch the platform positioning system between the first operational state and the second operational state with regard to a position information concerning the relative position between the platform and the cabin and/or the wall segment, wherein the position information depends on sensor data measured by a position sensor, further wherein the control unit is connected to the position sensor.

9 . The platform positioning system according to claim 7 , wherein the control unit is configured to switch the platform positioning system between the first operational state and the second operational state with regard to an operation information, further wherein the operation information depends on a control command generated by a user via an operating device.

10 . The platform positioning system according to claim 9 , wherein the control unit is configured to control the operation of the elevator with regard to an elevator information, further wherein the elevator information depends on a control command generated by the user via the operating device.

11 . The platform positioning system according to claim 9 , wherein the operating device is located within the cabin and/or on the platform and/or that the operating device is a remote device, which is wirelessly connected to the control unit.

12 . The platform positioning system according to claim 1 , wherein on a bottom side of the platform a safety device is located to catch objects falling down from the platform.

13 . A method for operating a platform position system with a platform and an elevator, wherein a transportation of the platform by a cabin of the elevator moving along a wall segment of a building comprises:
attaching the platform to the cabin by a first attachment means, moving the cabin together with the platform to a position where the platform is desired, attaching the platform to a wall segment by a second attachment means, and disconnecting the platform and the cabin.

14 . A wind turbine comprising the platform position system according to claim 1 .
