Description

  Provide unloading equipment for flat-top cargo ships. More precisely, an unloading device for a flat-top cargo ship having a deck is provided. The present invention also includes a method of unloading a load from a cargo ship.

  A “flat ship” is defined in this context as a ship with its deck load near or above the coastline. The flattop cargo ship may be a conventional non-self-propelled or self-propelled cargo ship.

  The so-called “flat ship”, which has a flat deck that generally functions as a loading space, is widely used and readily available. It is known to have such a deck with retaining walls extending from the deck to the information. The retaining wall is usually located near the edge of the deck.

  When used to transport sand, for example, to drain the surplus water from the sand while pumping fluid sand onto the deck so that the sand is placed on the deck to recover the soil from the sea The cargo may be loaded on the cargo ship. In general, drainage is generally carried out through perforations in the form of slits, through geotextiles on the retaining wall, or through agricultural pipes with holes drilled on or near the deck.

  According to the prior art, sand is wholesaled from the deck by the use of civil engineering equipment such as excavators or excavators. This unloading method has been found to be relatively time consuming and costly.

  The object of the present invention is to overcome or alleviate at least one drawback of the prior art.

  The object is achieved by the present invention by the features as disclosed in the following description and the following claims.

  An unloading device for a flat-top cargo ship with a deck is provided, and a water supply outlet is provided on, in or on the deck for cleaning muddy water or sand on the cargo ship.

  Depending on the location of the feed outlet in or on the deck, water supplied through the feed outlet will flow into the sand on the deck and slurry or wash the sand. When the feed outlet is located near the deck, the water enters the sand at a relatively low position and the water tends to slurry the sand rather than wash it. The water supply outlet may include a flow adjusting member such as an opening or a valve.

  The water supply outlet may communicate with a pipe located above, below or above the deck. In this manner, the pipe may have multiple water outlets that may be located on the deck, thus providing a low cost option for unloading equipment. Multiple pipes may be particularly advantageous on larger cargo ships.

  The water supply outlet may be held by a device independent of the cargo ship. A fixed or floating gantry system or excavator located on a cargo ship or an adjacent cargo ship may be useful, for example, to hold water outlets and tubes.

  It has been understood that depending on its location relative to the cargo ship, a water outlet may need to be connected through a pipe or ring to allow connection to a water pump. The water pump may be located above or outside the cargo ship. When located outside the cargo ship, the water pump may be more suitable for providing multiple cargo ships so that the water pump is only connected to the cargo ship during the unloading operation.

  Flattop cargo ships may have retaining walls to keep the sand in place on the cargo ship during loading and transportation. At least a portion of the retaining wall may be tilted or removable to facilitate unloading by fluidizing the sand.

  The retaining wall or deck may have an opening for discharging fluidized or washed sand leading to the outside of the cargo ship. For loading purposes, in particular, fluidized loading should be utilized and the opening should be closable. The opening need not be closeable for unloading purposes.

  The closeable opening can be equipped with a valve. Any type of valve suitable for the purpose may be used. The valve may be remotely controlled, for example, by a hydraulic ram.

A method of unloading sand from a flat-top cargo ship with a deck is provided,
-Providing at least one water outlet in or on the deck;
-Connecting the water supply outlet to the water pump;
Pumping water into the sand via a water outlet for slurrying or washing the sand;
-Flowing slurryed sand over the deck;
including.

  As mentioned above, the water outlet is usually connected to the water pump via at least one pipe or tube.

The cargo ship may have a retaining wall,
-Providing an opening in the deck or retaining wall;
-Flowing slurryed or washed sand through the openings;
May be included.

  The unloading apparatus and method according to the present invention, where the use of a relatively simple apparatus is proposed, provides a substantial reduction in the time and cost of unloading sand from a flat top ship.

  Examples of preferred devices and methods will now be described with reference to the accompanying drawings.

It is a perspective view of the flat top cargo ship which has an apparatus concerning the present invention. It is a figure which shows the pipe which has a water supply exit on a larger scale. It is a figure which shows the opening in the holding wall of the cargo ship in which a valve | bulb is located in a port opening. It is a perspective view of a self-propelled cargo ship. It is a figure which shows the outline of the front view of the cargo ship located under the gantry which carries a water supply exit. It is a figure which shows the outline of the front view of the cargo ship located adjacent to another cargo ship which has the excavator which carries a water supply exit.

  Reference numeral 1 on the drawing indicates a flat-top cargo ship having a deck 2. A retaining wall 4 extending upward from the deck 2 surrounds the deck 2 and serves to hold the sand in place on the deck 2 during loading and transport.

  In FIG. 1, the pipe 6 is located at the center of the deck 2. The pipe 6 includes a plurality of water supply outlets 8 along its length. In FIG. 2, the water supply outlet 8 is shown in the form of a stud pipe 10 with a flange.

  During unloading, the pipe 6 is connected to a water pump (not shown) in the form of a tube 12, preferably a tube.

  The retaining wall 4 is provided with a number of openings 14 for discharging the slurried sand. In this preferred embodiment, each opening 14 is provided with a valve 16 and can therefore be closed. The valve 16 is rotatable around a hinge 18 and is operated by a hydraulic ram 20. In FIG. 3, the valve 16 is shown in the open position.

  When unloading from a cargo ship, the pipe 6 is connected to a water pump (not shown) via the tube 12. Water is pumped through the feed outlet 8 to the sand to fluidize the sand. The valve 16 is opened, and the fluidized sand flows from the cargo ship 1 through the opening 14.

  In FIG. 1, the end of the retaining wall is shown in a tilted position to provide an opening 14a for discharging fluidized sand.

  FIG. 4 shows a self-propelled cargo ship 1 comprising the same device as shown on the cargo ship 1 in FIG. The self-propelled cargo ship 1 has a superstructure 22. The self-propelled cargo ship 1 is suitable for having a water pump (not shown) in a ship provided with a water supply outlet 8 with water.

  The gantry 24 on the float 26 includes a water supply outlet 8 that is relatively movable with respect to the gantry 24. The water supply outlet 8 is connected to the tube 12 with reference to FIG.

  The feed outlet 8 is on an excavator 28 that is carried by an independent cargo ship 30 as shown in FIG. The gantry 24 and the excavator 28 are examples of the support device 32.

  As water flows through the feed outlet 8 as shown in FIGS. 5 and 6, the water tends to wash the sand on the board.
