Embodiment Construction

[0028] The device 1 for enabling access to a rotor blade 2 of a wind turbine comprises a frame 3 . The frame 3 has connection means 4 to be connected to lifting means 5 in the form of ropes made of steel wire. The connection means 4 form a single connection point.

[0029] The frame 3 is triangular or in the form of the letter "A". This frame is oriented vertically with respect to the direction of gravity. The connection means 4 are located at the upper end of the triangle.

[0030] The frame 3 comprises two handles 6,7. Each handle 6,7 carries a platform 8,9. Each platform 8 , 9 forms a base for a gondola 10 , 11 .

[0031] Each gondola 10, 11 has access means 12, 13 in the form of a movable bar or door. The access devices 12, 13 of the two gondolas 10, 11 face each other so that in an emergency a person 14 in the gondola 10 can be rescued via the other gondola 11 or a person 15 in the other gondola 11 can pass through the second gondola. A hanging basket 10 were rescu...

Abstract

A device (1) for enabling access to a rotor blade (2) of a wind turbine is described, said device (1) comprising a frame (3) having connecting means (4) located at an upper region of said frame (3) and being structured in the range to be connected to a hoisting device. Such a device should be of simple construction, which is easy to control. To this end said frame (3) is in form of a triangle, said connecting means (4) being located in a region of an edge of said triangle.

Description

technical field [0001] The invention relates to a device for enabling access to a rotor blade of a wind turbine, said device comprising a frame with connection means located in an upper region of said frame and structured and arranged to be connected to lifting means. Background technique [0002] Such a device is known, for example, from EP 2 315 938 B1. [0003] Such devices are used to transport people to a blade of a wind turbine for maintenance at this rotor blade. This maintenance includes, inter alia, inspection, repair and cleaning of the blades. [0004] In many cases, the blades of a wind turbine are tilted relative to the direction of gravity. This tilting is considered necessary to avoid contact between the blades of the wind turbine and the tower during operation. [0005] Furthermore, the blades are in many cases slightly curved. This makes it difficult to move the device along the blade so that a person on a platform connected to the frame can reach the en...
