Automated receptor system
Provided is an automated receptor system of a sling-receiving element for gripping a connection device of a sling of a blade gripping device for gripping a rotor blade, in particular a rotor blade of a wind turbine, which automated receptor system includes a receptor for connecting the connection device to the sling-receiving element and a drive system for pivoting the receptor for coupling the connection device to the sling-receiving element and for decoupling the connection device from the sling-receiving element. Further a sling-receiving element and a blade gripping device are described. Furthermore, provided is a method for gripping a connection device of a sling of a blade gripping device for gripping a rotor blade, in particular a rotor blade of a wind turbine.
1. An automated receptor system of a sling-receiving element for gripping a connection device of a sling of a blade gripping device for gripping a rotor blade of a wind turbine, which automated receptor system comprises:
a receptor for connecting the connection device to the sling-receiving element,
a drive system for pivoting the receptor for coupling the connection device to the sling-receiving element and for decoupling the connection device from the sling-receiving element, and
a receptor locking system, wherein the receptor locking system is based on electromagnetic power and mechanical power, wherein, in case the receptor tries to open more, a crank and the receptor abut, which results in locking the receptor from further rotating.
2. The automated receptor system according to claim 1 , wherein the receptor comprises a hook.
3. The automated receptor system according to claim 2 , wherein the hook comprises a boring for receiving an axis of rotation.
4. The automated receptor system according to claim 1 , wherein the drive system comprises at least one of the following features:
a motor for driving the pivoting motion of the receptor,
a crank shaft for transmitting the driving power from the motor to the receptor,
a bearing for supporting the crank shaft and
a crank mounted on the crank shaft for transmitting the power from the crank shaft to the receptor.
5. The automated receptor system according to claim 1 , further comprising a detection system for detecting whether the connection device is in the correct position when closing the receptor.
6. The automated receptor system according to claim 1 , further comprising a connecting rod for connecting a crank shaft to the receptor for pivoting the receptor from a closed position into a released position and from the released-position into the closed position.
7. The automated receptor system according to claim 1 , further comprising a sensor system for detecting whether the drive system for pivoting the receptor has positioned the receptor in a closed or released position, wherein the sensor system comprises a sensor arm attached to a crank shaft and a sensor supported by a sensor mount.
8. A sling-receiving element for gripping a connection device of a sling of a blade gripping device for gripping a rotor blade of a wind turbine, which sling receiving element comprises an automated receptor system according to claim 1 .
9. A blade gripping device for gripping a rotor blade of a wind turbine, which blade gripping device comprises:
a sling-receiving element according to claim 8 .
10. The blade gripping device according to claim 9 , further comprising: a blade gripping tool comprising:
a sling and
an automatic sling handover mechanism comprising a sling-conveying element and a sling-receiving element, whereby the sling-conveying element is realized to convey a connection device of the sling along a two-dimensional predefined path of travel around a part of the rotor blade towards the sling-receiving element to connect to a receptor of the sling-receiving element.
