Abstract

The invention relates to a production mold for a rotor blade of a wind turbine plant, having two mold half-shells ( 3, 4 ) which during a production method of the rotor blade are disposed so as to be at least temporarily beside one another, and having at least one inner walkway ( 2 c, 2 d ) that runs along so as to be between the two mold half-shells ( 3, 4 ), characterized by at least one escape path ( 40 ) which runs along below at least one of the two mold half-shells ( 3, 4 ).

First claim

What is claimed is:

1. Production mold for a rotor blade of a wind turbine plant, having two mold half-shells ( 3 , 4 ) which are disposed beside one another, and having at least one inner walkway ( 2 c , 2 d ) that runs along so as to be between the two mold half-shells ( 3 , 4 ),
characterized by at least one escape path ( 40 ) which runs along below at least one of the two mold half-shells ( 3 , 4 ); and
characterized in that the at least one inner walkway ( 2 c , 2 d ) which has at least one operator opening ( 30 , 31 ) through which the escape path ( 40 ) is reachable from the inner walkway ( 2 c , 2 d ) is disposed between the two mold half-shells and in that the at least one inner walkway ( 2 c , 2 d ) is disposed along each of the mutually facing longitudinal sides of the mold half-shells ( 3 , 4 ), and each of the two inner walkways ( 2 c , 2 d ) has in each case one operator opening ( 30 , 31 ).

2. Production mold according to claim 1 , characterized in that the mold half-shells ( 3 , 4 ) have in each case one open side and are in each case disposed on a mounting installation ( 8 , 9 ), and the two mounting installations ( 8 , 9 ) are interconnected in an articulated manner and are foldable in a reciprocating manner from an opened position in which the two mold half-shells ( 3 , 4 ), the open sides thereof facing upward, are disposed beside one another, to a closed position in which the two mold half-shells ( 3 , 4 ), the open sides thereof facing one another, are disposed on top of one another, and the inner walkway ( 2 c , 2 d ) in the opened position runs along between the two mold half-shells ( 3 , 4 ).

3. Production mold according to claim 1 , characterized in that the escape path ( 40 ) connects an at least one operator opening ( 30 , 31 ) to an outer longitudinal side of one of the two mounting installations ( 8 , 9 ).

4. Production mold ( 1 ) according to claim 1 , characterized in that a positionally fixed mold half-shell ( 3 ) during folding remains so as to be positionally fixed on the ground, and a foldable mold half-shell ( 4 ) is foldable from the opened position to the closed position, while the escape path ( 40 ) is routed below the foldable mold half-shell ( 4 ).

5. Production mold ( 1 ) according to claim 1 , characterized in that a positionally fixed mold half-shell ( 3 ) is disposed on a positionally fixed mounting installation, and a foldable mold half-shell ( 4 ) is disposed on a foldable mounting installation, and the positionally fixed mounting installation and/or the foldable mounting installation are/is in each case configured as a steel framework ( 8 , 9 ).

6. Production mold ( 1 ) according to claim 1 , characterized in that an at least one operator opening ( 30 , 31 ) cover is lockable, and the cover has a closed position in which said cover is passable, and has an opened position in which the escape path ( 40 ) is accessible by way of a ladder ( 50 , 51 ) or a stairway or a sliding pole, for example.

7. Production mold ( 1 ) according to claim 1 , characterized in that the cover of an at least one operator opening ( 30 , 31 ) is a sliding hatch.

8. Production mold ( 1 ) according to claim 1 , characterized in that the cover of an at least one operator opening ( 30 , 31 ) is operable by way of an emergency switch ( 32 ) which is disposed at gripping height beside the at least one operator opening ( 30 , 31 ).

9. Production mold ( 1 ) according to claim 1 , characterized in that the cover of an at least one operator opening ( 30 , 31 ) is operable by way of a mechanism, for example a crank or a pump lever, which is disposed at gripping level beside the at least one operator opening ( 30 , 31 ).

10. Production mold ( 1 ) according to claim 1 , characterized in that each of the two operator openings ( 30 , 31 ) is connected in a passable manner to the same escape path ( 40 ).

11. Production mold ( 1 ) according to claim 1 , characterized in that side walls and/or floors and/or ceilings of the escape path ( 40 ) are composed of a fireproof or fire-retardant material.

12. Production mold ( 1 ) according to claim 1 , characterized in that side walls and/or floors and/or ceilings of the escape path ( 40 ) are cladded with a fireproof or fire-retardant cladding ( 41 ).

13. Production mold ( 1 ) according to claim 1 , characterized in that outer walkway frames 20 a and/or 20 b are disposed along outer longitudinal sides of the mold half-shells ( 3 , 4 ), and the escape path ( 40 ) is continued also through the walkway frames ( 20 a , 20 b ).

14. Production mold ( 1 ) according to claim 1 , characterized in that the outer walkways ( 2 a , 2 b ) and the at least one inner walkways ( 2 c , 2 d ) are configured as abutting tiles which are fitted onto walkway frames ( 20 a , 20 b , 20 c , 20 d ).
