Abstract

The invention relates to a device ( 10 ) for the hand-guided movement of loads by means of a retaining or gripping element ( 11 ) as a lifting aid, which retaining or gripping element is attached to a load-bearing rope ( 2 ), comprising a load-bearing apparatus ( 1 ), which is provided with at least one vertical cantilever ( 3 ), over which the load-bearing rope ( 2 ) is guided from sides of a rope-winding apparatus ( 4 ) on the load-bearing apparatus ( 1 ) by means of an adjustable rope articulation point ( 5 ), wherein a sensor ( 6 ) for measuring a rope angle of the load-bearing rope ( 2 ) in relation to the vertical is provided and a controller coupled to the sensor ( 6 ) is provided, which controller is designed to simultaneously control an adjustment of the rope articulation point ( 5 ) and a rope length of the load-bearing rope ( 2 ) on the basis of a measured rope angle.

First claim

The invention claimed is:

1. A device ( 10 ) for the hand-guided movement of loads by means of a retaining or gripping element ( 11 ) attached, as a lifting aid, to a load-bearing rope ( 2 ),
with a load-bearing apparatus ( 1 ) which comprises a cantilever ( 3 ) over which the load-bearing rope ( 2 ) is guided from sides of a rope winding device ( 4 ) arranged on a load-bearing apparatus by means of an adjustable rope articulation point ( 5 ), wherein a length of the load-bearing rope ( 2 ) can be adjusted with the rope winding device ( 4 ), characterized in that a sensor ( 6 ) is provided for measuring a rope angle of the load-bearing rope ( 2 ) relative to the vertical, and in that a controller that works together with the sensor ( 6 ) is provided, and is set up so as to bring about simultaneously a shifting of the adjustable rope articulation point ( 5 ) and a change in the rope length of the load-bearing rope ( 2 ) as a function of the rope angle measured with the sensor ( 6 ).

2. A device according to claim 1 , characterized in that the device comprises at least one actuating drive coupled to the controller, which is facilitated by the sensor ( 6 ), and configured for adjusting the rope articulation point ( 5 ).

3. A device ( 10 ) according to claim 2 , characterized in that the controller activates an actuating device, for the active tracking of the rope articulation point ( 5 ) in a direction towards the adjustment of the rope angle of the load-bearing rope ( 2 ) towards the vertical.

4. A device ( 10 ) according to claim 2 characterized in that the controller is designed in such a manner that, in the case of a sideways shifting of the load, the rope length between load and cantilever ( 3 ) is kept constant.

5. A device ( 10 ) according to claim 2 characterized in that a trolley ( 7 ), which can be shifted on the cantilever ( 3 ) is provided, the trolley comprising the rope articulation point ( 5 ), wherein the shifting of the trolley ( 7 ) is controlled by the controller.

6. A device ( 10 ) according to claim 2 characterized in that the load-bearing apparatus ( 1 ) comprises vertical support for the cantilever ( 3 ), which can be swiveled sideways and which is provided with an actuating drive for the active turning of the cantilever ( 3 ) about a vertical rotation axle.

7. A device ( 10 ) according to claim 2 , characterized in that the load-bearing apparatus ( 1 ) is a pivot arm cantilever with an additional vertical rotation axle, on which a pivot joint, which is adjustable via an actuating drive, is provided.

8. A device ( 10 ) according to claim 2 , characterized in that the sensor ( 6 ) is designed for measuring a deflection distance of the load-bearing rope ( 2 ), wherein the sensor ( 6 ) is arranged at a predefined distance beneath the rope articulation point ( 5 ).

9. A device ( 10 ) according to claim 2 , characterized in that the rope articulation point ( 5 ) is designed in the form of a deflection roll ( 8 ) with a lift-off protection ( 9 ).

10. A device ( 10 ) according to claim 1 , characterized in that the controller activates an actuating device, for the active tracking of the rope articulation point ( 5 ) in a direction towards the adjustment of the rope angle of the load-bearing rope ( 2 ) towards the vertical.

11. A device ( 10 ) according to claim 10 characterized in that the controller is designed in such a manner that, in the case of a sideways shifting of the load, the rope length between load and cantilever ( 3 ) is kept constant.

12. A device ( 10 ) according to claim 10 characterized in that a trolley ( 7 ), which can be shifted on the cantilever ( 3 ), is provided, trolley which comprises the rope articulation point ( 5 ), wherein the shifting of the trolley ( 7 ) is controlled by the controller.

13. A device ( 10 ) according to claim 1 characterized in that the controller is designed in such a manner that, in the case of a sideways shifting of the load, the rope length between load and cantilever ( 3 ) is kept constant.

14. A device ( 10 ) according to claim 1 characterized in that a trolley ( 7 ), which can be shifted on the cantilever ( 3 ) is provided, the trolley comprising the rope articulation point ( 5 ), wherein the shifting of the trolley ( 7 ) is controlled by the controller.

15. A device ( 10 ) according to claim 14 , characterized in that at least one actuating drive coupled to the controller is provided for the adjustment of the rope articulation point ( 5 ) in the longitudinal direction of the cantilever ( 3 ) and/or in a direction transverse to the longitudinal direction of the cantilever ( 3 ).

16. A device ( 10 ) according to claim 14 , characterized in that at least one actuating drive coupled to the controller is provided for the adjustment of the trolley ( 7 ) in the longitudinal direction of the cantilever ( 3 ) and/or in a direction transverse to the longitudinal direction of the cantilever ( 3 ).

17. A device ( 10 ) according to claim 1 characterized in that the load-bearing apparatus ( 1 ) comprises a vertical support for the cantilever ( 3 ), which can be swiveled sideways and which is provided with an actuating drive for the active turning of the cantilever ( 3 ) about a vertical rotation axle.

18. A device ( 10 ) according to claim 1 , characterized in that the load-bearing apparatus ( 1 ) is a pivot arm cantilever with an additional vertical rotation axle, on which a pivot joint, which is adjustable via an actuating drive, is provided.

19. A device ( 10 ) according to claim 1 , characterized in that the sensor ( 6 ) is designed for measuring a deflection distance of the load-bearing rope ( 2 ), wherein the sensor ( 6 ) is arranged at a predefined distance beneath the rope articulation point ( 5 ).

20. A device ( 10 ) according to claim 1 , characterized in that the rope articulation point ( 5 ) is designed in the form of a deflection roll ( 8 ) with a lift-off protection ( 9 ).
