Definitions

  • the stones which can be of irregular or regular configuration, are loaded upon barges, punts, or the like at a landfall and are carried on the water-borne vehicle to the region at which the stones are to be deposited, the vehicle being towed by a tug boat or other self-powered craft.
  • the barge is then anchored and the bulk cargo cast over the side, generally by hand.
  • the craft may be required to carry a deck load of about 100 tons of the bulk material, necessitating several days for its dispersal and a labor force of 6-8 workers.
  • Another object of this invention is to provide a craft for the controlled distribution of stones and the like along embankments, coastal strips and other areas bordering bodies of water which permits the transport of large quantities of the bulk material, is stable, and can effect the discharge of the bulk material at predetermined locations along the submerged ground to be covered.
  • a water-borne vehicle for the deposition or dockside bulk delivery of materials such as stone, coal, ores and like flowable solid cargoes which comprises an elongated floating hull whose cargo area lies at least partly below the water line and receives at least one but preferably a plurality of cargo-storage receptacles below the water line and disposed alongside a longitudinally extending conveyor means likewise located below the water line.
  • This main conveyor means advantageously feeds a lift means at one of its extremities whereby the bulk material is brought to or above the deck (i.e., above the water level) and deposited over the side of the hull, advantageously with the aid of an auxiliary conveyor means mounted upon the deck and extending over the side of the hull.
  • Means, preferably of the fluid-responsive type, is provided for each cargo-storage receptacle for tilting it so as to discharge its contents onto the main conveyor means.
  • auxiliary conveyor means which can extend transversely to the main conveyor means, can deposit the bulk material at a distance from the side of the vessel so that there is no danger of damage to the hull of the latter when work is carried out in shallow waters although the shallow-draft hull of the latter permits work close to the shore line.
  • main conveyor means is utilized herein, it is intended to designate both a single, longitudinally extending conveyor or a plurality of adjacent conveyors of this type.
  • At least two rows of cargo-storage receptacles are provided, one row along each of the lateral edges of the main conveyor means, the receptacles being successively tiltable to discharge their contents by means, for example, of hydraulically operated piston and cylinder arrangements. It should be noted, however, that other tilting means can also be used.
  • Still another feature of this invention resides in the use of a passive or active auxiliary conveyor means which is swingably mounted on the hull for rotation about a substantially vertical axis between positions wherein the conveyor means extends over the port and starboard sides of the hull.
  • This swingability permits deposition of the stones at any desirable location with respect to the craft and advantageously can occur over an angle in excess of about 250 so that the auxiliary conveyor means swings out over the bow or stern of the ship, depending upon which end of the main conveyor is the outlet.
  • the auxiliary conveyor means can be swingable through a full 360 or at least to such an extent that it can be disposed amidships when the ship is traveling to or from the location of discharge.
  • this auxiliary conveyor which as previously noted preferably extends transversely to the main conveyor means, is longitudinally extensible in step with the conveyance of the bulk material thereon so that the cargo is distributed progressively and uniformly in a direction transverse to the major dimension of the ship.
  • the means of effecting longitudinal displacement of the auxiliary conveyor can be hydraulic and coupled, as in the manner of servo follower with the belt drive, thereby obtaining essentially a stone-by-stone deposition of the cargo in a substantially contiguous manner.
  • the apparatus aside from being readily loadable, permits of total discharge of the cargo even when relatively wide fiat-bottomed hulls are employed.
  • the cargo-storage receptacles can have removable side walls, according to the present invention.
  • the main conveyor means can be protected from damage while loading by providing a shield means including a plurality of shield plates overlying the main conveyor and slidably displaceable therewith along a suitable guide means toward one end thereof for removal of these plates.
  • the adjusting means can, for example, include an extensible cable connecting to a portion of the transverse conveyor hinged to the support therefore about a substantially horizontal axis.
  • the lift means can comprise an extension of the main conveyor means or be independent therefrom, but preferably cooperates with a further conveyor juxtaposed therewith and serving to support the bulk cargo against any tendency to roll down along the lifting means.
  • FIG. 1 is a longitudinal cross-sectional view through a watercraft according to the present invention
  • FIG. 2 is a top-plan view thereof
  • FIG. 3 is a transverse cross-sectional view through the ship diagrammatically showing the cargo-storage receptacles thereof in elevation;
  • FIG. 4 is a perspective view of one of these receptacles
  • FIG. 5 is a longitudinal cross-sectional view through the main conveyor means, drawn to an enlarged scale
  • FIG. 6 is a transverse cross-sectional view through the main conveyor means in the scale of FIG. 5;
  • FIG. 7 is an elevational view diagrammatically illustrating the transverse or auxiliary conveyor means of the apparatus.
  • FIG. 8 is a fragmentary view similar to FIG. 1, illustrating a modification of the invention.
  • FIGS. 9-11 are diagrammatical transverse views similar to FIG. 3 showing the vessel in various stages of operation;
  • FIG. 12 is a view similar to FIG. 8 showing another modification
  • FIG. 13 is a circuit diagram ,of the means for automatically discharging the storage receptacles of the vessel.
  • FIG. 14 is a detailed view of the auxiliary conveyor means showing the mechanism for extending and retracting it over the side of the vessel.
  • FIGS. 1-7 I show a vessel for the transportation and dispensing of bulk material which comprises an upwardly open flat-bottomed hull 1 having the configuration of a shell whose bow is indicated at 1' and which is provided with a rudder at its stern 1".
  • a propelling screw together with its drive engine (not shown) can also be mounted in the stern with any necessary steering and control devices in a manner known per se.
  • a main conveyor 2 extends centrally along the bottom of the hull below its water line 1a and between two rows of cargostorage bins best seen in FIGS. 3 and 4. A plurality of such bins are arranged along each of the opposite lateral edges of the main conveyor 2.
  • the latter comprises a pair of guide rails 3 mounted upon a pair of supporting beams 7 and forming guide means for a multiplicity of contiguous individual shield plates 4 overlying the conveyor proper.
  • Shield plates 4 are provided with bentrod handles 5 whose downwardly projecting ends 5 constitute formations extending into the path of conveyor bars 6, a multiplicity of which are longitudinally spaced along and bridge a pair of conveyor chains 6' continuously displaceable along the vessel by a sprocket-drive means not illustrated. Chains 6' are received within the channels formed by beams 7 While a partition 2' extends between the upper and lower passes of the conveyor thus formed.
  • each of the receptacles 8 is provided with a telescopic piston-and-cylinder arrangement 9 articulated to the respective web 9' and extensible for tilting the bins.
  • the hydraulic device 9 can be energized via electromagnetic valves, as will be described hereinafter, and are fixed to the hull 1 of the vessel at support plates 9".
  • the main conveyor 2 is generally of the type employed in mines for the transportation of detritus.
  • each of the inwardly and upwardly open bins 8 is formed with side walls 8 removahly mounted in channel-shaped guides 8 so that these side walls can be withdrawn when the vessel is to be used for carrying cargo of large dimensions.
  • the forward end of the main conveyor 2 terminates at a lifting conveyor 10, which is inclined upwardly toward the deck 10 of the vessel above the water line, adapted to deposit the bulk material onto an auxiliary conveyor means 11.
  • Conveyor 10 can be of the belt or chain type as required although it is preferred to constitute the latter as a bucket conveyor (FIG. 2) whose compartments 10 prevent downward flow of the bulk material entrained by the conveyor.
  • Auxiliary conveyor 11 is rotatably mounted upon the base 12 on the deck 10' for angular displacement about a substantially vertical axis through at least 250 as indicated in FIG. 2 whereby the conveyor can discharge the bulk material over either the port or starboard side of the ship, the conveyor being swingable across the bow in this instance. It should be noted, however, that it is desirable to totally withdraw the conveyor 11 inwardly when the ship is not at its working station and for this purpose, the pivot mount 12 is arranged so that the conveyor 11 can be swung inboard (broken lines in FIG. 1).
  • a hopper 13 directs the cargo received from conveyor 10 onto the transverse conveyor 11 which can be of the belt or chain type previously described. From FIG.
  • the conveyor 11 can be a passive chute or a moving belt of bipartite construction so that the outer portion 11 of this conveyor is hinged to the inner portion 11" at 11a whereby this outer portion can be swung in a vertical direction by a cable 14' passing around a windlass 14" of an upright 14 to regulate the location of the discharge end of conveyor 11 with respect to the water level.
  • the lift conveyor 10 is swingable about an axis 10a (FIG. 1) generally transverse to the direction of conveyor travel so that it can be pivoted into the broken-line'position illustrated, whereby the transverse conveyor 11 can clear it when it is disposed amidships.
  • a flap 15 is pivoted at 15' at the discharge end of conveyor 2 for elevation furing unloading, this flap being closed (solid line position in FIG. 1) to prevent escape of the bulk material loading or transport.
  • FIG. 8 I show a variation in which the conveyor means 2 is provided with an upwardly inclined extension 2a at its discharge end, this extension 2a forming the lift means communicating with the funnel-shaped hopper 13.
  • the operation of the device will be immediately apparent from FIGS. 9-11, from whence it may be seen that the receptacles 5 alongside the conveyor 2 are in their lowered position for loading and that the bulk material (i.e. stone, coal, ore or the like) is received between the receptacles as well as within them.
  • the conveyor 2 is started, shield plates 4 are removed and the conveyor commences to carry the pieces of material to the lift means whereby it is elevated to hopper 13 for deposit over the side of the vessel by conveyor 11.
  • the bulk material between the two rows of recep tacles is discharged (FIG. 10) the individual receptacles can be successively tilted (FIG. 11) by automatic or manual controls to dump the contents upon conveyor 2 for subsequent discharge.
  • I provide a further conveyor 19 above the lift conveyor and preferably driven synchronously therewith via the chain-and sprocket mechanism 22 for engagement with the bulk material and support of the latter in its ascent.
  • the conveyor which is preferably swingable about an axis 19" at its upper end and has its lower end guided in a slot 19 for selfadjustment of the gap between the conveyors, is provided with projecting formations 18 which can be protuberances, swingable flaps or the like adapted to engage the bulk material form below and convey it upwardly.
  • FIG. 13 I show a system for automatically dumping the contents of receptacles 8, this system comprising a sensor 40 (eg a normally closed switch) which is held open as long as material 30 is conveyed by the chain 2.
  • a sensor 40 eg a normally closed switch
  • switch 40 When the quantity of material falls so that switch 40 closes, it energizes coil 41 to advance a stepping switch 42 whose individual cams 43 successively operate electromagnetic valves 44 associated with the respective hydraulic cylinders 9 of the receptacles.
  • the receptacles are then tilted in succession to dump their load upon conveyor 2 (FIG. 11), each receptacle being dumped only after the amount of material carried by the conveyor has dropped.
  • FIG. 14 there is shown a mechanism whereby conveyor 11 can be advanced or retracted over the side of the vessel.
  • a pair of guide rails 32 is provided along the lateral edges of the conveyor which is slidably mounted thereon.
