Abstract
The present invention relates to a cable winch, in particular a hoisting gear winch of a hoist, comprising a cable drum, an entry guide for a cable to be wound onto the cable drum, and an actuating drive for adjusting the entry guide relative to the cable drum. The invention also relates to a hoisting device, in particular in the form of a crane, having such a cable winch. According to the invention, a detection unit for detecting an image of the progression of the winding of the cable wound onto the cable drum is provided and the control unit is designed to adjust the entry guide relative to the cable drum depending on the winding progression image captured.
Claims23
A cable winch comprising a hoisting gear winch of a hoisting device, wherein the hoisting gear winch is for winding and unwinding a cable, the hoisting gear winch comprising:
- a cable drum;
- an entry guide for guiding the cable to be wound onto and unwound from the cable drum;
- an actuating drive for adjusting the entry guide relative to the cable drum;
- a controller for controlling the actuating drive;
- and
- an image evaluator configured to determine a deformation of flanged wheels, which together with a drum shell delimit a winding region of the cable drum and project beyond the drum shell, from an image of the cable drum,
- wherein the controller is configured to change an adjustment of the entry guide and/or to emit a warning signal and/or to stop winch operation when a predetermined flanged wheel deformation is exceeded.
A cable winch comprising a hoisting gear winch of a hoisting device, wherein the hoisting gear winch is for winding and unwinding a cable, the hoisting gear winch comprising:
- a cable drum;
- an entry guide for guiding the cable to be wound onto and unwound from the cable drum;
- an actuating drive for adjusting the entry guide relative to the cable drum;
- a controller for controlling the actuating drive;
- and
- an image evaluator configured to determine a deformation of flanged wheels, which together with a drum shell delimit a winding region of the cable drum and project beyond the drum shell, from an image of the cable drum,
- wherein the image evaluator is configured to identify a distance between the flanged wheels in a camera image and/or to determine a distance of each flanged wheel from a drum center, and
- wherein the controller is configured to change an adjustment of the entry guide and/or to emit a warning signal and/or to stop winch operation when a predetermined flanged wheel deformation is exceeded.
