Definitions

  • a bottom dump barge is comprised of a pair of barge sections hinged together along a longitudinally extending axis located at approximately the deck level of the barge.
  • an arm is secured to one barge section and extends in cantilever fashion transversely across the hinge axis to a point above the other barge section and a closing device is secured at its upper end to the free end of the cantilever arm and at its lower end to the other barge section. The closing member can be locked to retain the barge sections in the closed position.
  • the present invention is directed to a closing device for bottom dump hopper barges formedby two barge sections hinged together in the longitudinal direction, and more particularly, it is concerned with the combination of a cantilevered arm and a closing device for closing the barge sections.
  • the opening of the loaded hopper barges is accomplished automatically by the pressure of the cargo on the hopper bottom which extends obliquely downward from the sides to the center of the hopper section.
  • the longitudinally extending sections of the hopper barge are hinged together on an axis which is located approximately at the deck level of the barge.
  • Another device used in the past employs the hydraulic cylinder located outside the hopper in one barge section with the cylinder actuating a lever arrangement for locking the barge sections in the closed position.
  • the use of a lever arrangement tends to complicate the construction of the closing device.
  • an arm is attached to one of the barge sections and extends transversely in cantilevered fashion, toward the other barge section crossing the hinge axis of the barge.
  • a closing device such as a hydraulic cylinder and piston rod, is positioned in the barge with the piston rod attached to the cantilevered end of the arm and the cylinder pivotally secured to the other barge section.
  • Another feature of the arrangement of the present invention is the disposition of the closing member with its upper end secured to the arm being closer to a vertical plane through the hinge axis of the barge sections than the lower end of the closing member which is pivotally secured to the other barge section.
  • the cantilevered arm for pivoting the barge sections can be secured to a bulkhead limiting one end of the hopper transverse to the longitudinal direction.
  • the arm can be secured to the joint hinging the barge sections together or it can be spaced in the longitudinal direction from the hinge joint.
  • other suitable structural elements of the barge section can be employed in absorbing and distributing the forces transmitted by the arm.
  • Another feature of the invention is the ability to detachably secure the arm to one of the barge sections.
  • a device can be employed for locking them together whereby the closing member is not required for holding the barge sections together after they are moved into the closed position.
  • FIG. I is a schematic transverse sectional view of a bottom dump hopper barge embodying the present invention.
  • FIG. 2 is a partial top view of the hopper barge shown in FIG. 1;
  • FIG. 3 is an enlarged partial transverse view illustrating a latching means for securing the hopper barge sections in the closed position
  • FIG. 3a is a partial sectional transverse view similar to FIG. 3, but illustrating a different form of latching means
  • FIG. 4 is a partial side view taken along the lines IV-IV of FIG. 3;
  • FIG. 4a is a partial side view taken along the line IVa-IVa in FIG. 3a;
  • FIG. 5 is a schematic transverse sectional view, similar to that shown in FIG. I, and illustrating an alternate embodiment of the invention
  • FIG. 6 is a partial top view of the hopper barge shown in FIG. 5;
  • FIG. 7 is a schematic transverse sectional view, similar to that shown in FIGS. 1 and 5, and illustrating yet another embodiment of the present invention.
  • FIGS. 1 and 2 a bottom dump hopper barge is illustrated being comprised of two longitudinally extending barge sections 1 and 2 hinged together at joints 4 located at the deck level of the barge and spaced outwardly from a loading trough formed by the barge sections 1 and 2. In FIG. 2, only one of the joints 4 is shown. Due to the manner in which the barge sections 1 and 2 are articulated together the barge sections can be pivoted about a longitudinally extending hinge axis 5 located at approximately the deck level of the barge.
  • an arm 6 is rigidly secured to the barge section I and is integral with the transverse bulkhead limiting either the forward or rearward end of the hold 3.
  • the arm 6 extends, in cantilever fashion across the longitudinally extending hinge axis 5 laterally from the axis to a point located above the other barge section 2.
  • a hydraulic unit is pivotally secured to the arm.
  • the hydraulic unit extends downwardly into the barge section 2 and is pivotally secured at its lower end thereto.
  • the hydraulic unit is comprised of a piston rod 8 axially movably mounted within a cylinder 9.
  • the upper end of the piston rod 8 is connected at a hinge connection 7 to the cantilevered end of arm 6 while the lower end of the cylinder 9 is connected by means of a hinge connection 10 to the bottom of the barge section 2.
  • the barge sections 1 and 2 are in the closed position forming the hopper or hold 3 with the piston 8 being located in the extended or "out” position as shown in FIG. 1.
  • the piston rod When the piston rod is retracted into the in" position, the upper hinge connection 7 is displaced downwardly and the lower hinge connection 10 is displaced upwardly while the barge sections 1 and 2 separate from one another forming the bottom dump opening from the barge.
  • FIGS. 3 and 4 and 3a and 4a respectively, latching devices are shown for securing the barge sections in the closed position.
  • the barge sections are pivoted into the opened position by moving the piston rod 8 downwardly thorough the cylinder. Accordingly, if the piston rod and cantilever arms are blocked from effecting the downward movement then the barge sections 1 and 2 can be locked in the closed position.
  • a latching device 13 is articulated to the deck 11 of the hopper barge and is movable in the longitudinal direction by means of a small hydraulic cylinder and piston rod 12. With the latching means 13 disposed below the hinged connection 7, the cantilever arm 6 and the piston rod 8 are locked in place and the barge sections 1 and 2 will remain in the closed position. By retracting the hydraulic cylinder unit 12, the latching means can be removed and it is then possible to move the barge sections into the opened position.
  • a loose latch member 14 as shown in FIGS. 3a and 4a, is positioned in locking engagement with the hinge connection and the cantilevered end of arm 6 and is pushed into or removed from position by means ofa handle 15.
  • FIGS. and 6 As distinguished from FIG. 2, where the hinge joint 4 and the arm 6 are spaced from one another in the longitudinal direction, in FIGS. and 6, the arm 17 is integral with the hinged joint 16 pivotally securing the barge sections 1 and 2 about the hinged axis.
  • the hydraulic unit is mounted in a manner similar to that shown in FIG. 1 with the piston rod 8 pivotally secured to the hinge connection 7 at the cantilevered end of arm 17 and the cylinder 9 being pivotally secured to the hinged connection 10 at the bottom of the barge section 2. Accordingly, barge sections 1 and 2 shown in FIGS. 5 and 6 are moved between the closed and opened positions in the same manner as that described for FIG. 1.
  • FIG. 7 a different configuration of an arm 18 is shown as compared to the arms 6 and 17 illustrated in FIGS. 1 and 5, respectively.
  • the cantilevered arm extends transversely in a substantially horizontal plane across the deck level of the hopper barge, while, as shown in FIG. 7, the arm 18 slopes upwardly from the barge section 1 to a point above the barge section 2.
  • the hydraulic unit 8, 9 is disposed at a greater angle to the vertical plane through the hinge axis between the barge sections 1 and 2 and, moreover, a latch member 19 is provided for locking the barge sections in the closed position.
  • the barge sections 1 and 2 can be moved to the opened position of the hopper barge by retracting the piston rod 8 into the cylinder 9 which pulls the arm 18 downwardly and the hinge connections 7 and 10 between the hydraulic unit and the arm and barge section 2, respectively, being displaced about the hinge axis 5 corresponding to the movement of the barge sections 1 and 2 into the opened position.
  • the arms can be secured in a detachable manner to the barge sections. Further, it is also possible to reverse the directions of the arms at the opposite ends of the hopper 3 with each arm being secured to a different one of the barge sections and cantilevering over the other barge section. In such an arrangement, the hydraulic units at the opposite ends of the hold 3 of the hopper barge extend diagonally to each other.
