Definitions

  • ABSTRACT A connecting structure for ocean-going push-barge combination, wherein a plurality of connecting pins are provided at the bow and both sides of a pusher boat in a manner slidable back and forth, and corresponding numbers of holes or ports for receiving and holding connecting pins therein are provided in the wall of a longitudinally, deeply notched stern of a barge where the bow and the sides of the pusher boat enter, the pusher boat and the barge being rigidly but separably joined together by insertion into the receiving and holding ports of the connecting pins depending on the relative drafts of the pusher boat and the barge to form a single seagoing unit.
  • This invention relates to an oceangoing push-tug for pushing ships, barges, etc., and, more particularly, it is concerned with a connecting structure for the oceangoing pusher-barge combination, wherein both pusher boat and barge are rigidly joined and united together to form a single seagoing unit.
  • the so-called pushtowing or push-tug-system has recently been introduced and adopted with giant strides.
  • the reason for this remarkable tendency may be ascribed to the following: (I) a low construction cost; (2) less number of crew; (3) a greater tonnage for transportation than that afforded by a self-navigating barge (a freighter or cargo boat having in itself a driving power) in respect of the same draft; (4) a faster navigating speed than the'towing system by about 30%; and (5) the least difference in its steering performance from that of the selfnavigating boats.
  • FIG. 1 is a side elevational view showing a state of the oceangoing pusher-barge combination in the fullloaded barge;
  • FIG. 2 is a side elevational view showing a state of the oceangoing pusher-barge combination in the empty barge;
  • FIG. 3 is a top plan view showing a connection of the pusher boat and the barge;
  • FIG. 4 is a cross-sectional view showing the oceangoing pusher-barge combination when the barge is fullloaded
  • FIG. 5 is a cross-sectional view showing the oceangoing pusher-barge combination when the barge is emptyloaded
  • FIG. 6 is a side elevational view partly in crosssection showing a device for simultaneously inserting and retracting the connecting pins into and fromvthe receiving and holding ports on both sides of the boatbarge hulls, in the state of the connecting pins yet to be inserted into the receiving and holding ports;
  • FIG. 7 is also a side elevational view partly in crosssection showing the device for simultaneously inserting and retracting the connecting pins in the state of the connecting pins having been inserted into the receiving and holding ports in the barge hull;
  • FIG. 8 is a cross-sectional view showing another embodiment of the connecting pins and the receiving and holding ports for the pusher-barge combination
  • FIG. 9 is a cross-sectional view, partly enlarged, showing the coupled state of the tapered connecting pin and the receiving and holding port;
  • FIG. 10 is a cross-sectional view, partly enlarged, showing the tapered connecting pin and the receiving and holding port prior to their being coupled;
  • FIG. 11 is also a cross-sectional view, partly enlarged, showing the tapered connecting pin and the receiving and holding port when they are about to be coupled.
  • FIGS. 1, 2, and 3 which indicate the connection or coupling between a selfnavigating pusher boat A and a cargo-loading, dummy barge B having no self-propelling mechanism
  • the stern Ba of the barge B is provided with a deep indentation or concaved notch C to allow the bow of the pusher boat A to enter into
  • the pusher boat A is provided near the center part a of the left side (or port side) of the hull with a connecting pin 1 which is made projectionable and retractible by a hydraulic cylinder 2.
  • the boat is also provided near the center part b of the right side (or the starboard) of the hull with another connecting pin 4 which is made projectionable and retractible by another hydraulic cylinder 5.
  • the boat A is provided in the vicinity of its bow d with a connecting pin 7 which is made projectionable and retractible by a hydraulic cylinder 8.
  • the barge B is provided at the left side thereof with a receiving and holding port 3 near the stern D at a position corresponding to the connecting pin 1 so as to receive and hold the same therein.
  • the right side of the barge is provided with another receiving and holding port 6 near the stern E at a position corresponding to the connecting pin 4 so as to receive and hold the same therein.
  • a receiving and holding port 9 to receive and hold therein the connecting pin 7 provided at the bow d of the pusher boat A.
  • the basic structure for the pusher boat-barge connection according to the present invention is therefore to rigidly join the pusher boat A and the barge B together at a plurality of points (in the above-described embodiment, it is at three points).
  • the state of the connection should naturally be different according to the cargo loading on the barge, i.e., whether it is full-loaded or empty-loaded.
  • the receiving and holding ports formed in the wall of the deeply notched stern are provided in at least the upper and lower lines as shown in FIGS. 4 and 5.
  • the connecting pin 1 at the left side is inserted and held by a receiving and holding port 3' for the empty loading formed below the receiving and holding port 3
  • the connecting pin 4 at the right side is inserted and held by a receiving and holding port 6 for the empty-loading formed below the receiving and holding port 6, and the connecting pin 7 at the bow thereof is inserted into a receiving and holding port 9' for the empty loading provided below the receiving and holding port 9 for the full loading and held therein by means of the cylinder 8.
  • both connecting pins 1 and 4 are simultaneously operated by a common cylinder as indicated in FIGS. 6 and 7.
  • the left side connecting pin 1 is connected to a piston 11 by way of an end arm 1, a connecting arm 16, and another connecting arm 15' which is secured at one end of a piston rod 12 for the piston 11, while the right side connecting pin 4 is connected to the piston 1 1 by way of an end arm 4', a connecting arm 16' and the other end of the connecting arm 15.
  • the left side connecting arm 16 and the right side connecting arm 16 are pivotally connected at their one end to both ends of the connecting arm 15 by means of pivot pins 18 and 18, while the end arms 1' and 4' of the connecting pins 1 and 4, respectively, are pivotally connected at the other end of the connecting arms 16 and 16 by means of pivot pins 20 and 20.
  • a small connecting arm 17 for the leftside and another small connecting arm 17 for the right side pivotally fitted at their one end on the respective fulcrums 21 and 21 provided at certain position on the cylinder are pivotally connected at the other end thereof to the central position of the connecting arms 16 and 16 by means of pivot pins 19 and 19, respectively.
  • Length of the small connecting arms 17 and 17 is made half a length of the connecting arms 16 and 16.
  • the ports 22 and 23 are for feeding lubricant into the guide path for the connecting pins 1 and 4, and the receiving and holding ports 3 and 6 to enable the connecting pins to smoothly slide along the guide paths and the portsfor their intromission and withdrawal.
  • connection of the pusher boat; A and thebarge B can be released by the reverse operation to the above. That is, when the pressurized fluid is sent into the cylinder 10 throughthe fluid passage port 14, the piston 11 moves toward the fluid passage port 13, whereupon the left side connecting pin 1 and the right side connecting pin 4 withdraw from the respective receiving and holding ports 3 and 6 andthe pusher boat A and the barge B are thus separated.
  • the advantage to be derived from this simultaneous connecting system is such that,.while the piston 11 is positioned near the fluid passage port 13, the shifting speed of the connecting pins land 4 along the direction of the line X-X is faster than the shifting speed of the piston 11, and, as the piston is going to be close to the fluid passage port 14, the shifting speed of the connecting pins 1 and 4 on the straight line X-X" becomes slower than the shifting speed of the piston 11, in the course of which thethrusting force of the connecting pins 1 and 4 augments to ultimately attain the infinity, so that even if a large external force is imparted to both connecting pins 1 and 4, sufficiently large inserting and retracting force counter to such external force can be obtained with the connecting pins.
  • the connecting pins and the corresponding receiving and holding ports are shaped in a tapered form as shown in FIGS. 9, 10, and 11 so as to obtain more rigid and tight coupling between the connecting pin and the receiving and holding port free from any gap or clearance between them to minimize undesirable vibrations and shocks caused by such gap to the pusher boat A and the barge B as combined.
  • each of the tapered connecting pins 1, 4, and 7 is connected to one end of a piston rod 24 of each of the cylinders 2, 5, and 8, and is made freely slidable back and forth along the guide path 25.
  • each of the tapered receiving and holding ports 3, 6, and 9, and the outer surface G of each of the tapered connecting pins 1, 4, and 7 may be as it is, or be coated with an elastic material such as rubber, neoprene, or the like, although the connecting pin and the receiving and holding port are formed in such a manner that, in their engaged state, there exists no gap or clearance between them.
  • each pair of the connecting pins and the receiving and holding ports can be sufficiently press-contacted each other without anyclearance whatsoever between them with the result that there is no possibility of the undesirable impact being caused to the boat and barge combination. That is to say, the impact is a phenomenon which takes place by collision of two moving objects, and, for the collision to take place, a certain moving distance should be presenLHowever, as in the present invention where no clearance exists between the connecting pin and the receiving and holding port, there is no moving distance between the pin andthe port, hence no possibility of the impact taking place between them.
  • a pressure accumulator 26 is provided on each of the cylinders 2, 5, and 8 so as to constantly impart the hydraulic pressure to the piston.
  • the piston rod 24 constantly acts to press-contact the tapered connecting pins 1, 4, and 7 to the receiving and holding ports 3, 6, and 9.
  • the connecting pins 1, 4, and 7 are in the tapered or conical shape, they can be readily inserted into and coupled with the receiving and holding ports 3, 6, and 9, even if there arises a difference a between the center line P--P of each of the connecting pins 1, 4, and 7 and the center line SS of each of the receiving and holding ports 3, 6, and 9 due to difference in the drafts between the pusher boat and the barge caused by the degree of cargo loading on the barge B and the weight of equipments on the pusher boat A.
  • the connecting pins 1, 4, and 7 move outward in the arrow direction Y by means of the piston rod 24 which is actuated by feeding a pressurized fluid into each of the cylinders 2, 5, and 8 for each connecting pin, and in the course of the outward shifting of the tapered connecting pins, even when it happens that the tapered end M of the connecting pin touches the corner surface L of each of the receiving and holding ports 3, 6, and 9, the pin can be easily thrusted into the receiving and holding ports 3, 6, and
  • the pusher boat and the barge can be perfectly and n'gidly joined into a single seagoing unit which is free from undesirable vibrations and shocks caused by collision of the hulls of the pusher boat and the barge, whereby not only the connecting structure and various instruments equipped in the pusher boat can be prevented from damages, but also any unpleasantness felt by the crews due to such vibrations and impact can be removed.
  • the connecting pins and the receiving and holding ports of the conical shape are adopted in this connecting system, the gap or clearance between the connecting pins and the receiving and holding ports can be perfectly eliminated, and, moreover, even if there exists a difference in the draft between the pusher boat and the barge, the connecting and separating operations can be carried out without difficulty.
  • the receiving and holding ports which are arranged in two upper and lower lines, as shown in FIGS. 1 through 5, of (3, 6, 9) and (3', 6', 9) may be made in multiple stages as shown in FIG. 8.
  • the connecting pins can be inserted into any appropriate port of a level in accordance with the relative drafts of the pusher boat and the barge, hence precise adjustment in the connection depending on the draft becomes feasible.
  • a connecting structure for an ocean-going pushbarge combination which comprises:
  • said boat including at least three connecting pins respectively located at the bow and both sides thereof; said connecting pin at the bow extending generally axially of the boat in a forward direction and said connecting pins on the sides of the boat extending outwardly therefrom in opposite directions; said pins being slidably mounted in the boat for movement outwardly and inwardly thereof;
  • a barge having a longitudinally extending stern including a notch formed therein which extends extirely through the stern of the barge and has a configuration generally complementary to the bow of the barge to permit entrance thereinto of the bow and both sides of said pusher boat, where said connecting pins are located, while the bow of the boat remains in the water
  • said stern of the barge having generally vertically extending side walls defining the notch and having a plurality of recesses therein for receiving and holding, said connecting pins, when said pins are protruded from said pusher boat, said receiving and holding recesses being located in groups at positions corresponding to those of said connecting pins, when the boat is received in said notch with the recesses in each group being located in generally vertically spaced alignment;
  • C. means in said boat for extending and retracting said pins into and out of the recesses in the barge that are generally aligned therewith, whereby said pusher boat is adapted to be rigidly but separably joined to the barge at a plurality of points on the bow and the two sides thereof to form a single ocean going unit when said pins are extended, while the pins can be released from the barge and reengaged with other recesses therein to accommodate a change in the relative drafts of the boat and barge without movement of the boat out of said notch.
  • said means for extending and retracting said connecting pins includes means for extending and retracting at least the pins on the sides of the boat simultaneously with each other.
