Definitions

  • the invention relates to an apparatus for cleaning a wall of a cargo hold of a ship according to the introductory portion of claim 1.
  • Cleaning cargo holds is typically done by hand, while ship personnel or harbour personnel scrub the walls clean with the aid of fire-hoses and scrubbing brushes. This is labour-intensive work and occupies much time which is at the expense of sailing time and during which time space is occupied in the harbour.
  • the cleaning element is designed as a brush, rotatable about a horizontal axis.
  • the suspension is formed by an arm which, with the interposition of a vertically movable cylinder, is pivotably suspended from a support beam of a portal which can be brought to a position reaching over a cargo hold.
  • the brush can be moved along the bottom and the walls of the cargo hold and the brush can be moved between the operative position and the position of rest.
  • a drawback of this apparatus is that in the position of rest, it occupies much space and that the cleaning requires relatively much time.
  • An object of the invention is to provide a solution for cleaning a wall of a cargo hold, which occupies less space and with which the walls can be cleaned more rapidly. According to the invention, this object is achieved by providing an apparatus according to claim 1.
  • the cleaning element occupies little space in the substantially horizontal position of rest.
  • the substantially vertical orientation of the cleaning element in the operative position further results in that with horizontal displacement of the cleaning element in operation, in one go, a cleaned path with a greater height along the wall of the hold can be obtained, so that cleaning a wall can be carried out in a shorter period of time.
  • the invention can also be embodied in a portal crane with an apparatus according to claim 1, and in a ship with a portal and an apparatus according to claim 1.
  • Figs. 1-3 show, in a schematic manner, an apparatus according to the invention, a portal crane for moving ship's hatches, and a ship's hull.
  • Fig. 1 shows the apparatus in an operative position
  • Fig. 2 shows the apparatus in an intermediate position
  • Fig. 3 shows the apparatus in a position of rest.
  • a cleaning element 2 of the apparatus In the operative position, a cleaning element 2 of the apparatus is in a position against a wall 7 of a cargo hold 8 from which, for instance, a cargo of dry bulk goods has been unloaded, in order to clean this by removing remainders and/or reaction products of an unloaded cargo and/or contamination from the walls.
  • the cleaning element 2 has an elongated form and is pivotably suspended, via a suspension formed, according to this example, by an arm 3 and a cardan universal joint 10, from a horizontal support beam 4 of a portal crane 5.
  • the cleaning element 2 In the operative position, the cleaning element 2 is suspended, oriented in a substantially vertical direction, from the arm 3.
  • the elongated cleaning element In the position of rest, the elongated cleaning element is directed substantially horizontally.
  • a motor winch 16 and a line 17 which is coupled via a bearing block 18 to the cleaning element 2, form an operating element with which the cleaning element 2 can be raised from the operative position to the position of rest and vice versa.
  • a portal crane comparable to the portal crane 5 shown for, inter alia, moving hatches 13 for closing off and releasing the cargo hold 8.
  • the hatches 13 are moved with the aid of means for moving the hatches 13 formed by hoisting hooks 11, and stacked in front of and/or behind the opening that gives access to the hold 8, in a manner shown by way of example.
  • the cleaning element As the cleaning element is elongated and, hence, has a slim shape, it can be stored in the position of rest in a compact manner along a support beam 4. This, in turns, allows for the cleaning element 2 to be suspended from a portal crane 5 which also serves for opening and closing the hatches 13 and to then leave sufficient space below the portal crane 5 for the hatches13, so that the functionality of the portal crane 5 is not impeded. Owing to the slim shape of the elongate cleaning element 2, sufficient space is left free below the support beam 4 for stacked hatches (see Fig. 3), so that the use of the crane 5 for moving the hatches is not impeded.
  • the cleaning apparatus 2 needs not comprise a separate portal for bearing the cleaning apparatus, which yields an important savings on space, weight and costs.
  • the cleaning element 2 in the position of rest, has a height that less than 1/10 the length in horizontal direction thereof
  • the use of the cross beam 4 of the portal crane 5 has as an advantage that an already present crane 5 can be used for bringing and holding the cleaning apparatus 2 in the hold 8, and moving it at least in the longitudinal direction of the ship. Consequently, it is not necessary to therefore provide a separate supporting structure on the deck.
  • the cleaning element 2 is designed in the shape of a brush.
  • the cleaning element can also be designed as, for instance, an assembly in the form of an arm provided with a row of nozzles, scrapers, a combination of, for instance, sprayers with a detachable brush, a detachable arm, etc. It is also possible to design the cleaning element as an assembly in the form of a row of brushes which are each rotatable about an axis transverse to the longitudinal direction of the elongated cleaning element.
  • a drive 6 enables rotation of the brush 2 about a longitudinal axis 9 and hence, cleaning of the wall 7 by brushing it.
  • the drive 6 is designed as an electric motor.
  • the drive may also be accommodated elsewhere, for instance in the cleaning body or on or in the support beam, and coupled to the arm for driving rotational and/or axial movement of the cleaning element via the arm.
  • the apparatus is moved along the wall 7 of the hold 8 by driving the portal crane 5 in the longitudinal direction of the ship.
  • the wall 7 of the cargo hold can be cleaned in a simple manner.
  • the work area on the wall 7 of the elongated cleaning element 2 i.e. the surface portion on the wall that is cleaned by a cleaning element held thereagainst or close to it in the operative position, is elongated in vertical direction, upon vertical movement with a compact cleaning element 2 along the wall 7, a cleaned path over the wall is obtained that has a greater height.
  • the wall 7 can be cleaned very rapidly with a cleaning element 2 which occupies little space in the position of rest.
  • the surface portion of the wall 7 that is cleaned by a cleaning element held thereagainst or close to it in the operative position preferably has a height-width ratio slimmer than 1:10.
  • the support beam 4 is provided with a rail guide 19 along which the apparatus can be moved in a direction transverse to the longitudinal direction of the ship. This also enables cleaning of the transverse partitions bounding the hold in longitudinal direction of the ship, by moving the cleaning element in a direction transverse to the longitudinal axis of the ship along the respective wall. By, simultaneously, moving both the portal in longitudinal direction of the ship and the cleaning element 2 in longitudinal direction of the cross beam 4 (i.e. transversely to the ship), also, any surface portions of walls of the cargo hold which, viewed in top plan view, extend obliquely relative to the longitudinal axis of the ship can be cleaned.
  • the arm 3 from which the cleaning element 2 is suspended extends in the same direction as the longitudinal axis of the cleaning element 2.
  • the cleaning element 2 can move translatingly at least relative to a portion of the arm 3 in the longitudinal direction of the arm 3 and of the cleaning element 2.
  • the cleaning element 2 can be raised from the operative position in vertical direction.
  • This enables the apparatus as a whole to be shorter, so that an apparatus with a vertical reach greater than the width between the legs of the portal 5 can be stored in the position of rest along the support beam 4.
  • the support beam 4 is often located relatively high above the deck so as to leave space below the support beam for stacked hatches. It is also possible, for that matter, that the axial pulling inwards and extending outwards of the arm 3 is carried out during downward and upward pivoting, respectively, of the cleaning element 2 between the operative position and the position of rest.
  • the movability of a portion of the cleaning element 2 in the longitudinal direction thereof is realized in that the arm 3 is composed of several telescopically retractable and extendable sections.
  • the arm can also have a fixed length and be connected to the cleaning element such that it can partly slide into or around it.
  • the cleaning element 2 in the operative position, the cleaning element 2 reaches, essentially, over the entire height of the wall 7 of the hold 8, so that when it passes over the wall 7, this is cleaned over its entire height.
  • the cleaning element 2 can be repeatedly moved along the same path over the wall 7.
  • the cleaning element can be vertically moved to and fro.
  • the cleaning element 22 is suspended from a yoke 32 which, by means of cables 40, is suspended in a raisable and lowerable manner from the support beam 24, for moving the cleaning element 22 in vertical direction.
  • a cleaning element 22 suspended from a yoke 32 that is suspended in a raisable and lowerable manner from the cross beam 24 of the portal 25, it is possible, in the operative position, with a cleaning element 22 suspended from a lowered yoke 32, to reach the wall portions near the bottom of the hold 8, while, in the upward pivoted horizontal position of rest (Fig.
  • this cleaning element 22 has a length that is much smaller than the distance between the support beam 24 of the portal 25 and the bottom of the hold 8 and, therefore, fits between the legs of the portal, which legs are closer together than the distance between the support beam 24 and the bottom of the hold 8.
  • the portal 25 is provided with hoisting eyelets 31 with which the hatches 13 can be moved, stacked and unstacked.
  • the yoke 32 is dimensioned such that it fits in a space left free by a yoke for moving hatches 13.
  • the apparatus may also have been suspended from a yoke of a portal crane that also serves for moving the hatches.
  • the apparatus in the position of rest, the apparatus may be uncoupled from the yoke and be suspended from the portal crane.
  • the yoke can also be used for, for instance, moving the hatches without being hindered by a cleaning apparatus suspended therefrom.
  • the yoke 32 is provided with means (not shown), for instance a rail guide, which enables movement of the cleaning element 22 transversely relative to the ship for cleaning the partitions bounding the cargo hold 8.
  • FIG. 6 a variant on the example shown in Figs. 4 and 5 is represented.
  • two cleaning elements 22 are suspended from the yoke 32 in positions against, or at least close to the walls 7 to be cleaned, so that two opposite side walls 7 can be cleaned simultaneously while the portal 25 is moved in longitudinal direction of the ship.
  • Using two cleaning elements operating simultaneously is also possible as variant on the example discussed first (Figs. 1 - 3) in which case the cleaning elements can be attached, each via their own suspension 3, 10, to the support beam 4.
  • the two brushes 22 are suspended in a manner such that in the position of rest, they have a parallel orientation relative to each other.
  • the brushes 22 can have an orientation at an angle relative to the support beam and, in lowered operative condition, can hang down in a common plane perpendicular to the longitudinal direction of the ship.
  • the cleaning element 22 should preferably be urged with a force in horizontal direction against or towards the wall 7.
  • a reaction force will be applied to the cleaning element, pushing the cleaning element away from the wall.
  • Brushes too should preferably be pressed with a normal force against a surface to be cleaned therewith. Applying such a reaction or normal force at a great distance below the support beam 24 would demand exertion of great moments to the suspension.
  • the cleaning elements 22 are coupled to a supporting arm 14 which is fastened at a distance below the support beam 4 between the cleaning elements 22, the cleaning elements 22 can be pressed at a distance below the support beam 4 in horizontal direction towards the walls 7 without it being necessary to exert great moments on the cleaning elements 22 or to the suspension.
  • the supporting arm 14 Prior to the pivotal movement towards the position of rest of the cleaning elements 22, the supporting arm 14 can for instance be uncoupled therefrom and remain behind in the hold, or be hoisted upward separately.
  • a foldable support 47 is coupled via a bearing block 18 to the cleaning element 2, and is hingedly coupled by its other end to the support beam 4.
  • the support 47 can apply a pressure force to the cleaning element 2, so that the cleaning element 2 can be pressed against the wall 7.
  • the support can also be of slidable or telescopic design.
  • the apparatus can also be equipped with one or more electromagnets coupled to the cleaning element or to the cleaning elements, for applying an attractive force to a steel wall of the cargo hold, for pulling the cleaning element against the wall of the cargo hold.
  • guide sections can be provided, arranged in the hold and along which one or more runners, coupled to the cleaning element or the cleaning elements, can run for guiding the cleaning element or the cleaning elements in the operative condition along the walls of the cargo hold.
