Definitions

  • German Printed Application No. 1,149,632, dated S- 1963 Primary Examiner-Trygve M. Blix Attorney-Woodhams, Blanchard and Flynn A hopper barge with a driving and control means supporting platform mounted thereon for constant horizontal orientation in any position of the barge sections.
  • a hopper barge arranged with lengthwise hinged sections for opening and closing thereof is provided with a deck-mounted platform for the support of drive, steering and other control mechanism.
  • Linkages are arranged between the platform and the adjacent portions of the barge deck so that the platform remains in horizontal orientation at all times regardless of whether the barge sections are in closed or open relationship with respect to each other.
  • linkage systems used are mounted pivotally but nontranslatably with respect to each section of the barge and the platform, or other supported means, is likewise mounted pivotally but substantially nontranslatably with respect to the barge sections whereby, regardless of the open or closed relationship of the barge sections with respect to each other, the platform for the engine, steering or other control mechanism remains at least substantially centered at all times over the centerline of the barge.
  • the invention relates to a hopper barge and particularly to a hopper barge for the transporting of dredged material or the like which barge can be driven by driving means preferably consisting substantially of a motor and a steerable propeller with longitudinally pivotable barge halves which support the driving means by means of a movable device, such as a platform, or the like connected to the barge halves.
  • the barge halves will be called floating body elements hereinafter.
  • Such a support for the driving means is to maintain the driving means and, if necessary, the platform for the helmsman during the pivoting process in a substantially horizontal position.
  • a type of hopper barge is already known in which the driving means is pivoted onto one of the floating body elements by means of a rigidly mounted joint, consisting of pivot pin and bearing support, and to the other floating body element by means which are transversely movable.
  • the platform is not maintained in a horizontal position by this system.
  • a hopper barge is presently known in which the platform which, of course, does not support a driving means, is maintained in a horizontal orientation by means of a vertical, columnlike sliding bar which is connected to the floating body elements by means of a linkage system.
  • Another known hopper barge also uses a vertical sliding bar for supporting the platform, but in this case the unit comprising the sliding bar and platform is connected to the floating body elements by a pair of straight guide rails instead of by links or rods.
  • a vertical bar or column acting at the side of the driving means or the platform does not well follow a straight guiding relationship.
  • the basic purpose of the invention is to make possible the separation of the floating body elements with the driving means or platform maintained in a horizontal position but without the need for a special guiding means, such as a vertical rod or the like.
  • the invention provides that the device supporting the driving means is connected to both barge halves by means of joints consisting of pivot pins and bearing supports or the like. It is thus assured that the central vertical plane of the driving means, if said plane coincides before the pivoting with the central vertical plane of the barge, remains during pivoting at all times on, or at least parallel to, the angle bisector of the pivoting barge halves.
  • a device embodying the invention can be constructed by mounting the driving means on a support which is in turn connected to both floating body elements by means of pivot means and is in itself telescopically longitudinally variable. This embodiment results in a very simple device.
  • a further embodiment of the invention contemplates supporting the driving means by at least one pair of rods which consists substantially of two intersecting linkages which are pivotally connected at the platform and at the floating body elements and are themselves connected scissorlike at the point of intersection.
  • a very advantageous embodiment of the invention is obtained if the driving means is supported by at least one pivotally connected linkage consisting of two four-hinge connections. It is advantageous to further develop this construction of the invention so that both four-hinge connections share at least one member acting as a rod, whereby three joints of both four-hinge connections can be mounted to one floating body element.
  • FIG. I schematically illustrates a top view of one embodiment of a hopper barge.
  • FIG. 2 schematically illustrates a si-de-elevational view of the hopper barge according to FIG. ll.
  • FIG. 3 schematically illustrates a device of the invention with the floating body elements in closed position.
  • FIG. 4 illustrates the device according to FIG. 3 with floating body elements in open position.
  • FIG. 5 schematically illustrates the embodiment of the invention according to FIGS. 3 and 4 with the addition of a driving means.
  • FIG. 6 schematically illustrates a further embodiment of the invention.
  • FIG. 7 schematically illustrates a further embodiment of the invention with closed floating body elements.
  • the control means and tie rods are indicated only schematically by lines and the joints by points.
  • FIG. 8 illustrates also schematically the embodiment of FIG. 7 with open floating body elements.
  • FIG. 1 schematically illustrates a hopper barge in a top view.
  • the hull is lengthwise divided along its center so that it consists of two halves l0 and Ill. Both halves are hingedly connected in a known manner near the deck so that they can open downwardly.
  • the halves are therefore to be identified hereinafter as floating body elements.
  • the construction of these elements including the air chambers, hinge and driving means for the pivoting movement is already well known and therefore not described with the exception of one embodiment in which the mechanism for supporting the driving means is used according to the invention as a driving means for the floating body elements.
  • a driving means 13 is installed on the deck at the stem 12 of the watercraft, which driving means 13 consists substantially of a motor 13, power transmitting means, a fuel supply system, a steerable propeller l5 and a piloting position 16.
  • the hopper barge can also, if desired, be driven by a conventional propeller, for example, through a so-called Z-drive, and can be steered by a conven tional rudder.
  • steerable propellers are particularly advantageous; therefore, the invention in combination with a steerable propeller or with a unit identified as a navigator (containing substantially a frame, driving means, transmission means, control means and steerable propeller means) is of particular importance.
  • the stern of the barge is provided with a recess 17.
  • a steerable propeller I8 is also to be provided at the how, a recess (illustrated in dashdotted lines) can also be appropriately there provided.
  • FIGS. 3 and 4 illustrate one embodiment of the invention.
  • the two hingedly connected floating body elements 10 and 11 support a platform 25 with hinges consisting of bearing supports 21, 22 and pivot pins 23, 24.
  • the platform supports the driving means 113.
  • Both halves of the platform are joined together in such a manner that they are telescopically variable in width.
  • the two halves of the platform can telescope to take up the change of distance between the hinges.
  • the central vertical plane of the driving means which, before pivoting, coincides with the central vertical plane of the hopper barge remains, as a result of the invention, during such pivoting in, or at least parallel to, the bisector of the angle which is formed by the decks of the floating body elements.
  • the platform remains horizontal at all times.
  • FIG. 5 illustrates a development of the embodiment of FIGS. 3 and 4 in which the one platform half 27' is provided with a cylinder 29 and the other half 28' with a piston 30.
  • the floating body elements By supplying pressure means to the cylinder chambers 32 and by emptying the other chamber 31 by means of conduits 33, 34, the floating body elements can be opened or such opening can be maintained.
  • a hydraulic or pneumatic driving means a mechanical or electrical drive can also be used.
  • FIG. 6 illustrates a further advantageous embodiment of the invention in which the driving means 13 or the supporting platform 35 is supported with respect to the two floating body elements 10 and 11 by at least one pair of links 36, 37 which intersect scissorlike and are pivotably connected at the point of intersection by means of a pivot pin 38 or the like.
  • the links are connected according to the invention to the floating body elements and the platform by pivots 39, 40, 41, 42 consisting of suitable pivot pins and bearings or the like.
  • FIGS. 7 and 8 A further very advantageous embodiment of the invention is illustrated in FIGS. 7 and 8.
  • the device is illustrated only schematically by illustrating the rod-shaped members as lines and the joints as points.
  • the driving means 13 or the supporting platform 43 is connected to the floating body elements 10, 11 by means of a system which consists of two four-hinge connections 44, 45.
  • the platform 43 and the decks 46, 47 of the floating body elements are considered for purposes of constructing a force diagram as rods.
  • the hinge 20 between the floating body elements is considered one of the joints.
  • One of the link quadrangles consists of the deck of the floating body element 10 (rod 46), the hinge (joint 20), the deck of the floating body element 11 (rod 47), the joint 50 provided on the deck, the rod 48, the joint 51, the rod 55 which is pivotably secured to the joint 54 on the deck of the floating body element 10.
  • the other link quadrangle consists of the joint 54, the rod 55, the joint 51, the platform (rod 43), the joint 52, the rod 49 which is secured on the deck of the floating body element 10 with the joint 53 and the portion of the deck of the floating body element l (rod 46') which lies between the joints 53 and 54.
  • the lengths of the common rod 55 and its point of engagement 54 at the deck of the part are chosen according to the invention in such a manner that during rotation of the rods 46, 47 on the joint the rod 48 is pivoted outwardly sufficiently that, due to the connection by the rod 43, the rod 49 is pivoted outwardly to the other side to the same extent. In this manner, the rod 43 (platform) remains horizontal.
  • This principle can also be used with other rod lengths.
  • the rods 48, 49 do not need to be in a vertical position but can also be inclined. It is important that the length of the rod 55 and the position of the joints 54 are chosen accordingly.
  • FIGS. 7 and 8 two systems according to FIGS. 7 and 8 are provided for supporting the platform, namely one such system adjacent the stem end and one adjacent the bow end of the driving means or the platform. In this case, it is advantageous to permit both rods 55 to cross each other.
  • the rod 55 is shared by both four-hinge connections
  • this statement refers to the ideal system. in an actual construction, the members 46, 47, 48, 55 can, for example, be positioned in another plane with respect to the members 43, 49, 46' so that the common element is not immediately apparent.
  • the rod 55 is pivoted to a joint 54 on one side, which joint is positioned on a floating body element and is pivoted on the other side to a rod 48 which is arranged on the other floating body element so that when the floating body elements pivot to open, the rod 48 is pivoted outwardly.
  • This drive can consist, for example, of at least one hydraulic cylinder which is suitably arranged between the floating body elements, for example, with a horizontal lateral axis.
