  • FIGA HYDRAULIC CONTROL MECHANISM FOR HOPPER BARGES FIELD AND BACKGROUND OF THE INVENTION
  • This invention relates to a hydraulic control mechanism for hopper barges consisting of two barge halves hinged or articulated to each other along a longitudinal axis of the barge.
  • the two barge halves can be spread apart to a certain angle, to provide a gap of corresponding width in the bottom of the loading space or hopper.
  • hydraulic cylinders For the purpose of opening and closing such a hopper barge, hydraulic cylinders usually are provided in one of the end portions of the barge, and are mounted either below or above the axis of articulation in dependence on whether the latter is at the deck level or is below the deck level.
  • the present invention therefore is directed to the problem of finding a solution which obviates such a drawback. It is of no consequence whether or not the component parts used in the invention system are new, as the main consideration is, instead, the general arrangement which is necessary for the operation of the device under all switching conditions. Accordingly, the objective of the invention is to provide, in addition to the first hydraulic cylinder-piston actuator, 21 second hydraulic pressure actuator mounted, in a known manner, in the other end portion of the hopper barge and connected, through a common pressure line to the first actuator, together with an additional pressure fluid tank located near the second actuator and connected thereto through a suction line and to the first or main pressure fluid tank through an interconnection line.
  • a flow line extends between opposite ends of the cylinder of the second actuator and is provided, in a known manner with a check valve therein, and two check valves, connected in parallel and opening in mutually opposite directions, are provided in the common pressure line interconnecting the two actuators, one of the these two check valves being spring-loaded.
  • the switching valve advantageously may be brought into three positions.
  • the first position for opening the loaded hopper barge
  • the piston rod sides of both hydraulic cylinders are-connected to the piston head side of one cylinder and also to the return line eading to the main or first pressure fluid tank.
  • the second position for closing the empty hopper barge
  • the pressure side of the pump is connected to the pressure line leading to the piston rod side of both hydraulic cylinders
  • the piston head side of one hydraulic cylinder is connected to the return line.
  • the third position for opening the empty hopper barge
  • the pressure side of the pump is connected to the piston head side of only one hydraulic cylinder, and the pressure line leading to the piston rod sides of both hydraulic cylinders is connected to the return line.
  • An object of the invention is to provide an improved hydraulic control mechanism for a hopper barge consisting of two barge halves articulated to each other along a longitudinal axis of the barge.
  • Another object of the invention is to provide such a mechanism which obviates the disadvantages of known mechanisms for this purpose.
  • a further object of the invention is to provide such a mechanism including respective fluid pressure actuators at opposite ends of the barge and each connected to a respective fluid pressure tank, with one fluid pressure actuator being connected to a fluid pressure pump, and with a switching valve controlling the interconnection and operation of the two fluid pressure actuators in a novel manner.
  • FIG. 4 is a schematic diagram of the hydraulic system.
  • the hopper barge shown in FIGS. 1, 2 and 3, comprises, in the usual manner, tow barge halves 1 and 2 which are articulated to each other. in the central longitudinal plane of the barge and at the deck level, by means of hinges 3. ln the central zone of the hopper barge, a load trough 4 is provided, and is illustrated batched in FIGS. l and 2.
  • This load trough 4 after the barge halves l and 2 have been spread apart as shown in F IG. 3, opens downwardly so that the load, consisting of loose material, is automatically discharged, the discharge being favored by the inclined lateral faces of the trough.
  • the hydraulic actuating means comprises two bydraulic actuators, of the piston-cylinder type, indicated at 5 and 6, and these are mounted at the opposite end portions of the hopper barge outside load trough 4 and below the hinge axis, to extend transversely of the hinge axis.
  • the cylinder is hinged to one of the barge halves, and the free ends of the associated piston rods, extending from the other end of each cylinder, are hinged to the other half of the barge.
  • the hydraulic control mechanism of the invention includes a circulation line mounted in the zone of one of the hydraulic cylinders 5, i.e. in the end portion of the hopper barge in hich cylinder S is provided.
  • the circulation line comprises four line portions 7, 8, 9 and 10, of which portions 7 and 8 are connected to opposite ends of the cylinder of actuator 5, at one end, and, at the opposite end, to a switching valve 11.
  • the line portions 9 and 10 connect switching valve 11 through a pump 12 and a throttle section 13, respectively, with a main or first pressure-fluid tank 14.
  • a check valve 23 is provided between pump 12 and line portion 7.
  • a suction line 16 leading into an additional or second pressure-fluid tank 15 is connected to the piston head side of the cylinder directly, and to the piston rod side of the cylinder through a check valve 17 opening only in the direction of the piston rod side of the cylinder.
  • Pressure-fluid tank communicates with the first pressure-fluid tank l4 through an interconnecting line 18.
  • both actuators 5 and 6 are interconnected by a pressure line 19 in which two check valves 20 and 21 are mounted in parallel so as to open in mutually opposite directions.
  • One check valve namely the check valve Zl opening in the direction of the hydraulic actuator 6, is loaded or biased by a spring 22 acting in the closing sense.
  • the switching valve ll can be brought into any one of three positions a, b and c in which the line portions 7, 8 and 9, 10 of the circulation line connected thereto may be interconnected through passages provided in the different parts of the switching valve and in accordance with the desired operation to be effected.
  • the switching valve ll is in its intermediate position b in which pump 12 is connected to line portion 7 and line portion 8 is connected to line portion 10 having the throttling device 13 therein.
  • the position a in which switching valve ll is shifted to the right, corresponds to an opening operation produced solely by the weight of the load placed in the load trough 4 of the barge, and without any action of pump 12.
  • hydraulic fluid can flow from the piston rod sides of the cylinders of both actuators 5 and 6 through pressure line 19 to the piston head side of the cylinder of hydraulic actuator 5, the volume in excess flowing through line portion 10 and throttle section 13 into the main or first pressure-fluid tank 14.

  • pump 12 furnishes a closing pressure, which is necessary for secure hermetic sealing of the two barge halves.
  • This closing pressure is supplied, through pressure line 19, to the pistons of both hydraulic actuators.
  • the closing pressure is higher than the spring pressure in check valve 21 which is positioned in the line leading to hydraulic actuator 6.
  • Position 0 in which switching valve 11 is shifted to the left, corresponds to the operation producing opening of the empty barge.
  • pump 12 furnishes hydraulic pressure fluid from tank 14 through the crosswise interconnected line portions 9 and 8 of the circulation system to the piston head side of the cylinder of hydraulic actuator 5, and the hydraulic fluid from the piston rod side of this cylinder can flow through the other two also crosswise interconnected line portions 7 and 10 of the circulation system and the throttle section 13 back into tank 14.
