Definitions

• the present invention relates to a cargo handling arrangement on a cargo ship in accordance with the preamble to the following patent claim 1.
• Cargo handling arrangements on cargo ships for side loading and unloading are previously disclosed. Examples of such arrangements are so-called side loading arrangements on ships, where the load in the form of cargo, such as general cargo, is carried on several decks in the ship on various levels, in conjunction with which a cargo hoist is arranged in a shaft and is capable of vertical displacement between the different decks.
• an unloading station Arranged in conjunction with an opening in the ship is an unloading station, which is situated at an appropriate level above a quay.
• the loading station can be used for loading the ship via the cargo hoist and onto the various decks. In relation to the load capacity of the ship, very often with large decks on several levels, the loading station very often represents a restriction of the load capacity.
• WO 9524336 proposes a system for loading and unloading a container ship.
• the ship is equipped with a first hoist, which moves vertically inside the ship, and with a second hoist, which moves on the outside of the ship, together with horizontal conveyors, which move between the hoists.
• the zone between the hoists is used as a buffer zone for the cargo.
• the object of the present invention is to increase the cargo capacity for a certain hoist capacity or hatch opening size.
• the aforementioned object is achieved by means of an arrangement in accordance with the present invention, the characteristic features of which can be appreciated from the following patent claim 1.
• Fig. 1 illustrates one embodiment of a cargo handling arrangement in accordance with the invention as a schematic cross section through a ship next to a quay;
• Fig. 2 is a schematic side view of a section of the ship with the cargo handling arrangement in accordance with the invention
• Fig. 3 is a schematic view from above of a larger section of the ship showing the loading deck
• Fig. 4 is a schematic view from above showing one of the upper cargo decks.
• Fig. 1 shows a schematic cross section through a ship, which is moored alongside a quay 4, which is situated at a level 5 that can vary relative to the ship, on the one hand between different ports, on the other hand due to the actual height of the tide, and also due to the actual weight of the cargo on the ship.
• Two different quay levels are illustrated in Fig. 1.
• the opposite side 3 can also be provided with loading openings.
• the ship is provided, as can be appreciated from Fig. 1 , with a number of decks 8-14, which are accessible to the cargo handling arrangement 1 in accordance with the invention.
• Each deck exhibits along one side an inner unloading opening 15 that is so arranged as to be closed between loading occasions by means of an inner hatch 20, which is illustrated in Fig. 1 in both an open and a closing position.
• the inner hatches are pivotally suspended about hinges on their upper edge.
• Arranged on every deck or deck level is at least one, and in the illustrated example two, loading/unloading conveyors 16, 17 in the form of, for example, belt conveyors; see Figs. 2, 3 and 4.
• a hoist shaft 18 Arranged between the loading/unloading conveyors is a hoist shaft 18, that is to say an open space extending between all the decks, in which space a cargo hoist 19 is capable of vertical displacement between the cargo decks 8-14, that is to say it is so arranged as to stop at every deck level, including the loading/unloading deck 9.
• the loading/unloading conveyors 16, 17 are arranged to either side of the cargo hoist 19 or, more specifically, the hoist shaft 18, and they extend and have a working direction in the longitudinal sense of the ship in the illustrated example; see the double arrows 32. These conveyors 16, 17 serve as buffer conveyors and move with advantage intermittently. They can also with advantage have the same load capacity as the cargo hoist 19, which can similarly be provided with advantage with a conveyor and can possibly also accommodate a loading truck 21 , as indicated in Figs. 3 and 4. When loading general cargo of the load pallet type or container type, the loading truck 21 is used on the respective deck levels 8-14 for the purpose of moving the cargo between its position on the respective deck and the loading/unloading conveyors 16, 17.
• One of the cargo decks 8-14, cargo deck 9 in the illustrated example serves not only as a cargo deck for the stowage of the cargo on board the ship, but also as a loading and unloading deck, in conjunction with which the cargo opening or the cargo openings 6 are arranged on at least one side 2 of the ship, but possibly also on both sides of the ship, where a special loading and unloading arrangement 22 is also situated.
• the loading and unloading arrangement can be executed with advantage as a lifting arrangement of the telpher hoist type 25, which is capable of displacement between an inner position inside the ship and an outer position at an appropriate loading level above the quay.
• the crane is so arranged as to be retracted into the ship while the ship is under way, and, on the other hand, the mobile crane is capable of moving between an inner position for collecting/delivering cargo and an outer position for delivering/collecting cargo.
• the loading arrangement 22 in the illustrated example is executed with two parallel crane girders 23, 24 that are capable of displacement in their longitudinal sense in guides between an inner and an outer position and are situated at a high level so that they are able to project at the top into the cargo opening 6.
• transverse traveling carriage 25 which on the one hand is capable of travelling along the girders, and on the other hand permits the crane to travel transversely across the longitudinal direction of the girders to permit flexible handling in conjunction with the positioning of cargo in a desired location.
• both cargo openings are provided with a loading arrangement to permit a higher capacity or, alternatively, flexibility in the choice of loading station on a quay.
• the buffer zones 26, 27 are provided with buffer conveyors 28, 29, which have a direction of working in the direction of the double arrow 30, that is to say between the respective deck conveyor 16, 17 and the ship opening 6.
• a very effective flow of cargo with a maximum capacity in relation to the available transport routes is thus obtained by means of the cargo handling arrangement in accordance with the invention that is a constituent part of a total cargo handling system for the loading and unloading of cargo respectively to and from a cargo ship.
• the system is controlled by a control system with a number of proximity sensors on one or more of the conveyors, the separate deck conveyors 16, 17 and the buffer conveyors 28, 29 for the purpose of recording the presence of a load on the conveyors and, with a computer system, for controlling the conveyors for the stepped feed, and also for controlling the hoist and transmitting information to an operator in respect of the actual status of the cargo handling process.
• the successive, stepped feed of cargo, on the one hand on every deck, and on the other hand in conjunction with loading and unloading, on the one hand creates space for loading and on the other hand ensures that cargo is constantly available for unloading.
• a plurality of openings may be arranged on the side of the ship with a view to further increasing the cargo capacity, in conjunction with which a corresponding number of cargo hoists and cargo arrangements are arranged at the respective opening.
• the ship can be equipped with three or more receiving and delivery stations for mobile cargo units.
• the lifting crane can be of a pivoting type with extending crane girders.
• the telpher crane can be used alternatively with one or more crane girders.
