Definitions

  • the invention relates to a watercraft with a drive, which is in Area of the bow of the watercraft is located. It is about especially around watercraft with controllable drives.
  • This Watercraft are also known as water tractors.
  • the controllable drives can be a so-called rudder propeller or Cycloidal propeller of the type of a so-called Voith-Schneider® propeller his.
  • Such ships usually have a central fin. This is on Longstrip in its longitudinal median plane, in that area, referred to the longitudinal axis of the ship, which is at the other end as the drive is located.
  • Such ships are used in particular as tugs or tractors Maneuvering and escorting large transport ships, especially tankers. These ships will perform this task also known as an escort tug. This is when escorting Transport ship in motion and the escort tug is in the stern of the ship connected to the transport ship by a hawser. Falls on the big one Transport ship the rudder system and / or the main propulsion system, then the escort tug must exert large lateral forces to do this large transport ship to keep on the desired course. Therefore must as large as possible with the entire hull of the escort tug Shear force can be achieved.
  • the escort tug becomes like this with a fin used that the direction of travel of the ship is such that the fin after shows in front. This direction of travel is exactly the opposite of that of others Towing tasks known driving direction, where the fin points to the rear.
  • the current state of high-performance rowing technology includes Cross beam devices, jacking systems and special rudders with which maneuvering is already very efficient. The requirements are however in Increased over time, making further improvements desirable are.
  • the invention is therefore based on the object of a watercraft, in particular to design an escort tug such that as possible large lateral forces are achieved while driving and the transport ship securely on Course can be held.
  • the task is said to be minimal structural effort than with the previously known means can be achieved.
  • the inventors used an element that was already there is known, namely on a rotatably mounted roller. See “Ship & speak ", No. 4/1980. There is such a turnable at the rudder, thus aft Roller arranged. According to the invention, however, one such rotating roller arranged away from the drive, thus in the area of other end of the watercraft than where the drive is located. The thought is surprising in that it is for the shipbuilding engineer must have seemed unreasonable.
  • the rotatable roller arranged in the area of the fin, and there again preferably at that end of the fin that is away from the drive.
  • the rotatable roller is best in the longitudinal median plane or at least arranged in parallel. Its longitudinal axis runs either in the Vertical or inclined to the vertical at a certain angle, for example 10, 20 or 30 degrees.
  • the arrangement can be such that the rotatably mounted Roll lightly around a vertical axis or around one against the vertical inclined axis can be pivoted out of the longitudinal center plane.
  • the rotatably mounted roller is provided with a drive.
  • the roller can be set in one turn, with a Peripheral speed which is a multiple of the ship's speed Has.
  • the roller can have a profiled surface, for example one surface provided with cams or depressions.
  • the drive power is minimal. It is generally less than 50 kW.
  • the rotatable roller is expediently a control device assigned. This determines the direction of rotation or the speed of the roller or controlled these two sizes.
  • the control can be done in two ways: On the one hand, the control device can be a function of the transverse thrust direction of the main propulsion system and / or rudders that may be present, but on the other hand it can also be a function of the hawser position, that is, the direction of the hawser. This can be recorded, for example, as follows: The hawser is generally passed between two posts which carry rollers for guiding the hawser. The force that the hawser applies to one or the other post can be detected. The control device can then control the direction of rotation or the rotational speed of the roller or these two parameters as a function of the control variables mentioned.
  • roller must not necessarily be circular cylindrical. Rather, it can take the form of a Have cylinders with the cross section of a polygon. She also needs not to be cylindrical at all. Instead, for example have a cross section at different points of length is different. For example, in the area of Longstrip to a circular cross section with a relatively large Have diameters, and on the other, facing away from the ship's bottom End of a circular cross section with a relatively small diameter.
  • the invention will be applied to Towing vehicles with two drives, one of which is located on the one side of the median longitudinal plane.
  • Invention in a towing vehicle with only a single drive use.
  • two fins instead of one to provide, which are arranged in parallel next to each other, again one on one side of the median longitudinal plane.
  • the escort tractor shown in FIG. 1 has controllable drives 1. These are located on both sides of the longitudinal median plane of the tractor, and in the area of one end.
  • a fin 2 At the opposite end is a fin 2.
  • the fin 2 is with provided a roller 3 according to the invention. This doesn't show you here roller drive shown on the roller about its own longitudinal axis to twist.
  • the two tractor drives are 1 Voith-Schneider® propellers. Instead, other types of drive would come in Consideration.
