Abstract
Trailing cable winch and method of operation in which an axially stationary, rotating winding arm is disposed in a carrier tube and driven by a motor arranged in the carrier tube. The trailing cable winch is operable to deposit a trailing cable on an axially reversibly movable cable drum which is disposed on the carrier tube. The rotation of the winding arm is synchronized with the advancing of the cable drum, so that, during a linear movement of the cable drum, the advance per rotation of the winding arm corresponds exactly to the diameter of the trailing cable. In the end position of the cable drum, two cable layers are deposited above one another.
Claims11
Trailing cable winch comprising:
- an axially stationary, rotating winding arm which is disposed on a carrier tube and driven by a motor arranged in the carrier tube which is capable of depositing a trailing cable on an axially reversibly movable cable drum which is disposed on the carrier tube;
- wherein the rotation of the winding arm is synchronized with a movement of the cable drum such that, during a linear movement of the cable drum, a linear advance of the cable drum per rotation of the winding arm corresponds substantially to a diameter of the trailing cable, and in an end position of the cable drum, two trailing cable layers are deposited above one another;
- and
- wherein in the carrier tube, a multistage planet wheel transmission is arranged which is driven by a motor shaft of the motor and includes a secondary stage which drives a hollow cylinder situated in the carrier tube, a cylinder jacket of the hollow cylinder having a guide groove into which a guiding pin, connected with the cable drum, engages and, when the hollow cylinder is rotated, causes an advancing of the cable drum, the guiding pin being guided in an axial oblong hole in the carrier tube.
A trailing cable winch comprising:
- an axially stationary, rotating winding arm disposed on a carrier tube;
- a motor comprising a motor shaft arranged in the carrier tube and operatively arranged to drive the winding arm;
- a movable cable drum disposed on the carrier tube and operably arranged with the winding arm to be axially movable for depositing a trailing cable onto the cable drum;
- a multistage planet wheel transmission driven by the motor shaft arranged in the carrier tube, the multistage planet wheel transmission comprising a secondary stage operably arranged to drive a hollow cylinder situated in the carrier tube;
- and
- a cylinder jacket of the hollow cylinder comprising a guide groove into which a guiding pin of the cable drum is engaged such that when the hollow cylinder is rotated, the cable drum is axially moved by the guiding pin being guided through an axial oblong hole in the carrier tube;
- wherein a rotation of the winding arm is synchronized with the axial movement of the cable drum such that the cable drum advances an axial distance per rotation of the winding arm which corresponds substantially to a diameter of the trailing cable such that two cable layers are deposited above one another between end positions of the cable drum.
A method of depositing a trailing cable on a trailing cable winch, the trailing cable winch comprising an axially stationary, rotating winding arm disposed on a carrier tube, a motor comprising a motor shaft arranged in the carrier tube and operatively arranged to drive the winding arm, and a movable cable drum disposed on the carrier tube and operably arranged with the winding arm to be axially movable, the method comprising the acts of:
- synchronizing the rotation of the winding arm with the axial movement of the cable drum by way of a rotating hollow cylinder located inside the carrier tube including a guide groove on a cylinder jacket thereof into which a guiding pin, connected to the cable drum and guided in an oblong hole in the carrier tube, engages such that the cable drum advances an axial distance per rotation of the winding arm which corresponds substantially to a diameter of the trailing cable;
- and
- depositing two layers of the trailing cable between end positions of the cable drum.
