BACKGROUND OF THE INVENTION
The present invention relates to a plurality of cargo holds that are partitioned from each other by bulkheads, a dispenser that traverses the bottom of the cargo holds, and takes out the bulk material from the cargo hold, and a conveyor that sends the taken bulk material to the bow or stern In particular, it relates to a bulk carrier that can be made to stand by without worrying about tangling or damaging the control cable for the power of the dispenser and to properly follow the running of the dispenser. Is.
[0002]
[Prior art]
Indefinite solid cargo consisting of ores, coal, limestone, wood chips, grains, cement, etc., solid cargo, that is, bulk cargo loaded in cargo holds in bulk cargo ships that transport bulk materials by sea. It is well known to have an automatic cargo handling facility that unloads the land.
[0003]
As automatic cargo handling equipment, as shown in FIG. 6, a plurality of cargo holds 103 partitioned from each other by partition walls 102 from near the bow to the stern of the hull 101 are formed in a hopper shape and provided on their bottom walls. Bulk material dropped by the dispenser 105 from the slit-shaped discharge port 104 is placed on a conveyor 106 disposed below the same and sent to the bow side or stern side along the bottom of the ship, and then on the upper deck by the second conveyor 107. It is also known that a third conveyor 109 installed on the boom 108 is landed at a predetermined location on the wharf.
[0004]
It is an indispensable means for countermeasures against inundation as described in JP-A-54-42794, JP-A-5-124576, and the like. The portion where 106 crosses the partition wall 102 is watertightly closed by a door device as described in the above-mentioned JP-A-5-124576, etc., so that there is no risk that the inundation will sink over the entire hold. Yes.
[0005]
On the other hand, the dispenser 105 reciprocates in the longitudinal direction of the hull along the upper surface of the bottom wall of the cargo hold 103, and travels inside the mountain-shaped cover body 110 so as not to be buried in the bulk material. It is known that each of these cargo dispensers 105 is provided in each cargo hold 103 and reciprocates within each cargo hold 103, and this is relatively easy because the opening of the partition wall 102 is only the passage portion of the conveyor 106. While it is possible to ensure watertightness, it is inevitable that equipment costs increase due to the provision of a plurality of dispensers 105, and it is necessary to take out the bulk of each cargo hold 103 in a balanced manner. There are problems such as being complicated.
[0006]
On the other hand, it is advantageous in terms of equipment cost and operation control system to reciprocate the dispenser 105 over almost the entire length in the longitudinal direction of the hold as described in Japanese Utility Model Publication No. 2-333196. .
[0007]
And the cover body 110 which makes the discharge machine 105 reciprocate the bottom part of the cargo hold 103 divided into the plurality over the full length of the hull longitudinal direction is formed over the full length of the reciprocating section. Rails 111 are laid. The power and control cable 113 of the dispenser 105 is connected to the power supply terminal and the input / output terminal at the bow side or stern side end, and a hanger 114 attached at an appropriate interval is installed inside the cover body 110. It is a curtain system engaged with the rail 112, and repeats the extended state and the folded state following the travel of the dispenser 105.
[0008]
[Problems to be solved by the invention]
However, the power and control cable 113 must be connected to the terminal at the bow or stern side end in order to follow the dispenser 105, and for this purpose, it must be at least as long as the one-way travel distance of the dispenser 105. I must. In addition, a control cable is necessary for each control object of the dispenser, such as travel control and payout control, and it is inevitable that the total number of cables increases.
[0009]
In addition, as a countermeasure against inundation, the traveling space of the conveyor 106 installed between the bottom wall of the cargo hold 103 and the ship bottom of the hull 101 is water-tightly partitioned by the door device 115 at the partition 102 portion. It is necessary to divide the cover body 110 for each cargo hold 103 by the door device 116 at the partition 102 portion. In this case, the travel rail 111 and the guide rail 112 need only be cut by the length of the door, but the cable 113 cannot be cut, so the dispenser 105 is placed in the region of the cargo hold 105 closest to the connection terminal. The door device 116 must be operated in a state where the cable 113 does not cross the partition 102 portion.
[0010]
When each of the door devices 115 and 116 cooperates with the partition wall 102 to form an independent watertight block for each cargo hold 103, the cable 113 that is longer than the one-way travel distance of the dispenser 105 is in a state of hanging down for a long time. There is a concern that the cable 113 made of a large number of bundles may be entangled or collide with each other, or may collide with the wall of the cover body 110 and be damaged if the ship hull 101 is shaken greatly during the voyage.
[0011]
In the present invention, a plurality of cargo holds that are partitioned from each other by bulkheads and arranged in the longitudinal direction of the hull, and a cover body that is provided by longitudinally cutting each cargo hold, reciprocates over substantially the entire length of each cargo. Cables for power and control of the dispenser for a bulk carrier with a dispenser that pulls the bulk material from the bottom downwards and a conveyor that sends the bulk material to the bow or stern for landing. It solves the problem that there is a risk of being tangled or damaged during voyage and the fact that there are many opportunities for tangling and breakage due to the large number of this, and waiting in a stable state during voyage It is intended to be able to appropriately follow the running of the dispensing machine.
[0012]
[Means for Solving the Problems]
In order to solve the above-mentioned problem, in the first invention, the power and control cables of the dispenser are wound around the drum of the winding device mounted on the dispenser, and the power supply terminal and the input / output terminal are positioned at almost the intermediate position of the cover body Installed to connect the leading end of the cable.
[0013]
In the second aspect of the invention, the power and control cables for the dispenser are wound around the drum of the winding device installed at a substantially intermediate position of the cover body, and the power supply terminal and the input / output terminal are connected to the installation location of the winding device. Installed on the cover body in the same cargo hold area and connected the cable winding tip.
[0014]
According to the first and second inventions described above, the length of the cable is almost one-half of the one-way travel distance of the dispenser, and since it is wound around the drum, there is no fear that it will be damaged or broken even if it hangs down during standby. Further, the cable appropriately follows the running of the dispenser by being fed out or wound from the drum. Further, the cable is wound on the drum and the unloader is placed in a position close to the power supply terminal and the input / output terminal, or close to the winding device, so that the unloader and the cable are in the same cargo. It is possible to easily form an independent watertight block for each cargo hold in cooperation with the partition wall by blocking the cover body and the conveyor traveling space in the front and rear direction.
[0015]
If the control cable is an optical cable, the number of cables used is reduced, and handling can be facilitated because the cables can be combined with the power cable. Furthermore, when a cable support path is provided on the cover body for placing the cable fed from the drum and extending in a straight line, the cable can be fed and wound smoothly and appropriately.
[0016]
