Definitions

  • the invention relates to a device arranged on a portal that can be moved parallel to the ship to be unloaded, for unloading loose material from the holds of ships by means of a gripper arranged on a boom that can be raised and lowered and moved with a cable winch, which grips the load from the hold of the ship throws the picked up lot into a collecting bunker.
  • the known devices of the aforementioned type are all constructed according to the same principle, and that the unloading of the ships takes place by means of a gripper adapted in size to the size of the ships to be unloaded and to the unloading capacity, which is moved horizontally and vertically by one on the Device outrigger cat and a hoist winch.
  • the entire unloading device on the quay is designed to be movable parallel to the ship to be unloaded over the entire length of the hatch of the ship.
  • a collecting bunker is generally arranged on the supporting frame in the area above the quay, into which the gripper drops the loose material picked up in the ship.
  • the gripper must on the way from the pick-up of the lot in the ship's hatch to the discharge of the lot over the collecting bunker, both vertically and horizontally, in full condition and also - when returning - in empty condition, a relatively wide range Travel away.
  • the weight of the gripper determines the design of the entire device, so that the known devices have a very high weight. The costs for original equipment and operating costs are correspondingly high. This is the decisive disadvantage of the known devices.
  • the object of the invention is to considerably shorten the required paths of the gripper in order to be able to reduce its weight, so that the device can be designed to be less complex and therefore less expensive.
  • That the boom is provided with a boom belt extending to below the collecting bunker;
  • a swivel boom is arranged on the water-side end of the boom, over which the hoist rope of the gripper is guided, which is moved by a cable winch.
  • the device according to the invention represents a completely new concept compared to the known devices described.
  • no significant horizontal movement of the gripper is required anymore, because the collecting bunker is located in the area above the ship hatch.
  • the slight horizontal movement of the gripper which is required to move the gripper into the correct ejection position
  • the swivel boom is used to bring the collecting bunker back and forth.
  • the swivel boom enables the gripper - after picking up loose material from the ship's hatch and after lifting the gripper by means of the cable winch to almost the edge of the collecting bunker - by swiveling backwards into the discharge position over the collecting bunker and again to move back. This process is repeated every time the gripper works.
  • the swivel path of the swivel boom is adjusted accordingly in operation depending on the respective boom inclination.
  • the gripper Because the gripper only has a small amount of travel, it can be made much smaller and thus lighter. However, since the weight of the gripper determines the design of the entire device, the device according to the invention can be made at least 50% lighter than known devices.
  • the vertical gripper movement is always only on the minimum required path between the surface of the batch and the Discharge height of the gripper above the collecting bunker reduced.
  • the boom is arranged rotatable about a vertical axis. Due to the possible rotational movement of the boom in connection with its driveability parallel to the ship, any point in the area of the ship's hatch opening can be approached with the gripper without the gripper itself - as required in the known devices - having to carry out a horizontal movement.
  • the cantilever belt is designed to be reversible and a loading element is provided in the region of the axis of rotation of the cantilever.
  • a device configured in this way can be used both for unloading and for loading ships.
  • the known devices described were only suitable both for unloading and for loading ships if an additional conveyor belt was provided on the device portal. However, this required considerable additional technical effort and thus caused correspondingly high additional costs.
  • the loose material can be dropped directly into the ship from the discharge point of the boom belt located on the water-side end of the boom in loading operation.
  • dust-free guiding of the loose material into the interior of the ship is made possible by the fact that a telescopic chute, a corrugated edge belt, a bucket elevator or the like is attached to the water-side end of the boom. This also enables the gentle loading required for certain materials.
  • the loading device When the device according to the invention for unloading a ship is operated, the loading device is pivoted into a rest position under the jib by means of a winch.
  • Figure 1 is a schematic representation of a device in side view.
  • Fig. 2 is a schematic representation of another device, also in side view.
  • the device shown in FIG. 1 has a portal 2 which can be moved parallel to the ship 1 to be unloaded and on which a boom 3 which can be raised and lowered is arranged.
  • the boom 3 is rotatable about an axis A.
  • the hoisting cable 6 is moved by a cable winch 7 arranged in the rear region of the swivel arm 4.
  • a collecting bunker 8 under which a discharge element, for example a discharge belt 9 or a discharge channel or the like, is provided.
  • a boom belt 10 extending up to below the collecting bunker 8 is also arranged.
  • the gripper 5 After the gripper 5 has picked up the loose material from the ship 1, it is raised to approximately the edge of the collecting bunker 8 by means of the hoisting rope 6 and then pivoted by the swing arm 4 into its discharge position above the collecting bunker 8. There the gripper 5 opens and the loose material falls into the collecting bunker 8. The loose material is dosed and continuously drawn off through the discharge belt 9 located under the collecting bunker 8. The loose material is then transferred to the boom belt 10 arranged on the boom 3.
  • the cantilever belt 10 throws the loose material in the center of the cantilever rotary displacement onto the quay belt immediately below, or, if necessary, onto an additional intermediate conveyor which bridges the distance between the cantilever pivot point and the quay belt.
  • the cantilever belt 10 is designed to be reversible and in the area a loading member 11 is provided on the axis A of the boom 3. Furthermore, a bucket elevator 12 is attached to the water-side end of the boom 3.
  • This device is used for loading ships 1, the loose material being fed onto the delivery belt 10 by means of the loading member 11 and being passed on from there to the bucket elevator 12.
  • the bucket elevator 12 finally places the bulk material in the hatch of the ship 1.
  • the bucket elevator 12 When using the device for unloading a ship 1 shown in FIG. 2, the bucket elevator 12 is brought into the rest position designated by 12 '.

Abstract

Ce dispositif de déchargement de matières en vrac transportées dans les cales de navires (1) est monté sur un portique (2) mobile parallèlement au navire (1) à décharger. Le dispositif de déchargement comprend un grappin (5) qui est entraîné par un treuil à câble (7), est monté sur une flèche (3) pouvant être levée et abaissée et décharge les matières en vrac, saisies dans la cale du navire, dans un silo intermédiaire (8) situé à l'extrémité de la flèche (3) au bord de l'eau. La flèche comprend un convoyeur en porte à faux (10) qui s'étend jusqu'en-dessous du silo intermédiaire (8). L'extrémité de la flèche (3) au bord de l'eau comporte un bras pivotant (4) sur lequel le câble (6) de levage du grappin (5) est guidé, le câble de levage (6) étant entraîné par un treuil à câble (7) situé dans la zone postérieure du bras pivotant (4).
