Definitions

  • the present invention relates to a hoisting arrangement, especially for use on board a ship in connection with a freight opening, especially a side port opening, comprising at least one hoist carriage which is moveable along a guide column in a hoist shaft which connects the freight opening or the side port opening to different decks of the ship, where the hoist carriage carries via a pair of support arms a loading platform pivotably mounted relative to the hoist carriage for movement of the loading platform horizontally from a fore-and-aft position from a position within the hoist shaft of the ship via the freight opening or the side port opening to a fore-and-aft position in a position outside the side of the ship, the loading platform being moveable in a horizontal direction relative to the hoist carriage by means of a power means, such as a pressure medium cylinder, which is preferably jointed to the hoist carriage.
  • a power means such as a pressure medium cylinder
  • the present invention is as mentioned especially designed for use on board ships, but will also be able to find application for other purposes, for example in connection with freight openings on land vehicles or in connection with freight openings in structure on land, and the like.
  • the freight hoisting arrangement as indicated above is usually employed together with fork lift trucks, that is to say with a set of fork lift trucks on board the ship and a set of fork lift trucks on land, for respective loading and unloading by the freight hoisting arrangement.
  • the loading and unloading can occur via extra equipment which is connected to the freight hoisting arrangement, such as various types of conveyor belts or similar transport means.
  • the fork lift trucks place or fetch their respective unit of freight directly on the loading platform of the freight hoisting arrangement, in a position outside the side of the ship or in a position in the hoist shaft in the ship.
  • fork lift trucks there is meant not only trucks with loading forks, but also trucks with other gripping or lifting means which are specifically adapted according to particular types of units of freight.
  • a fright hoisting arrangement is known from EP-A-0268575.
  • a system where a loading platform can be swung from a position within the ship to a position outside the side of the ship, so that a fork lift truck on the quay can place the freight directly on or fetch the freight directly from the loading platform.
  • the known freight hoisting arrangement is arranged so that the hoist carriage by means of an outwardly projecting arm, which is revolvable about a first vertical axis on the hoist carriage, can swing the loading platform around about a second vertical axis. By this the loading platform can be swung around along an arc of a circle about the said first axis.
  • an arm system in the shape of a parallelogram can be formed between the hoist carriage and the loading platform, so that the loading platform during the swinging around along said arc of a circle is parallel displaced between a fore-and-aft position in a position in the hoist shaft and a fore-and-aft position in a position outside the side of the ship.
  • the loading platform is subjected at the same time as it is moved transversely also to a certain fore-an-aft movement relative to the ship. This necessary fore-and-aft movement is undesired for several reasons.
  • the loading platform can be moved in a position in a hoist shaft within the ship and in a position outside the side of the ship by means of a guide column which is rotatable in the ship for swinging the loading platform around between said positions.
  • the turning of the loading platform relative the guide column can occur by means of hydraulic-mechanical or electro-mechanical drive systems.
  • the movement of the loading platform in a pivotal arc involves an undesired movement of the loading platform in the fore-and-aft direction.
  • the aim is a solution with which a precisely rectilinear movement in perpendicular direction of the loading platform can be ensured with relatively simple means in a horizontal direction between the position in the hoist shaft and the position outside the side of the ship.
  • the freight hoisting arrangement according to the invention is characterised in that a first support arm is pivotably mounted at a first end about a first vertical axis on the hoist carriage and at a second end is pivotably mounted about a second vertical axis on first end of the second support arm, while second end of the second support arm is pivotably mounted about a third vertical axis on the loading platform, and that a first positive guide means connects first end of the second support arm to the hoist carriage, while a second positive guide means connects second end of the first support arm to the loading platform, for positively guiding the loading platform in a fore-and-aft position in a transverse movement in perpendicular direction between the position within the hoist shaft and the position outside the side of the ship.
  • the freight hoisting arrangement is characterised in that the arrangement comprises a pair of hoist carriages which are separately movable along their respective guide column in hoist shaft and are separately revolvable about their respective pair of support arms for swinging the respective loading platform about between a position in the hoist shaft and a position outside the side of the ship, and that loading platforms of the hoist carriages are adapted to be coupled together hydraulically and(or mechanically for joint movement vertically in the hoist shaft or horizontally between a position in the hoist shaft and a position outside the side of the ship.
  • Fig. 1 shows in plan elevation two hoist carriages in full lines in a position within the ship and in broken lines in a position outside the side of the ship.
  • Fig. 2 shows in plan elevation the one hoist carriage on a larger scale and with several details, illustrated in broken lines in a position within the ship and in full lines in a position outside the side of the ship.
  • Fig. 3 shows in side elevation a section of the hoist carriage according to Fig. 1 and 2.
  • Fig. 4 shows a detail of Fig. 3 with certain parts removed for the sake of simplicity.
  • Fig. 1 there is shown a section of a ship, where there is illustrated just within the side 10 of the ship a hoist shaft 11 which at opposite ends carries a guide column 12 and 13 respectively for their respective hoist carriage 14 and 15.
  • the hoist carriages 14, 15 are designed as mirror images and substantially identical and are adapted to function individually in an equivalent manner.
  • a turntable or a combined support and rotary bearing 17 with which the under member 16 is fastened to the one end 19 of a first support arm 20, for revolving the support arm 20 about a first vertical axis 19a (see Fig. 2).
  • the support arm 20 is provided with a combined support and rotary bearing 22 with which the first support arm 20 is fastened at a first end 24 of a second support arm 25, so that these are pivotable relative to each other about a common, second vertical axis 24a.
  • a support and rotary bearing 27 with which there is fastened a loading platform 29, for revolving the loading platform 29 about a third vertical axis 28a relative to the support arm 25.
  • a power means in the form of a hydraulic cylinder 30 has the one end 31a fastened to the hoist carriage 14 (or 15) and the opposite end 31b fastened to the first support arm 20.
  • the loading platform 29 In the pushed out position of the power means the loading platform 29 assumes a position within the ship, such as shown by the full lines in Fig. 1, and in the retracted position of the power means the loading platform 29 assumes a position outside the side of the ship, such as shown by broken lines in Fig. 1.
  • a first positive guide means 32 is arranged in the form of a piece of wire between the hoist carriage 14 and a guide and fastening means 33 on the said first end 24 of the second support arm 25. More specifically the wire extends from a first fastening point 34 on the hoist carriage 14 via a first guide means 35 on the hoist carriage 14, substantially parallel to the first support arm 20 to the guide and fastening means 33 on the second support arm 25 and further substantially parallel to the support arm 20 and via a second guide means 36 on the hoist carriage 14 back to a second fastening point 37 on the hoist carriage 14.
  • the guide means 35 and 36 are arranged at a considerable radial distance from the first vertical axis 19a and are arranged on their respective mutually opposite sides of the hoist carriage 14.
  • the guide and fastening means 33 is arranged at a considerable radial distance from the second vertical axis 24a on the support arm 25.
  • the positive guide means 32 By means of the positive guide means 32 one can ensure that the third vertical axis 28a is moved precisely rectilinearly and transversely of the freight opening or the port opening by said revolving of the arm 20 relative to the hoist carriage 14, such as shown by the line 18.
  • a second positive guide means 38 is shown in the form of a piece of wire between the loading platform 29 and a guide means 23 and a fastening point 39 (Fig. 4) on the second end 21 of the first support arm 20. More specifically the wire extends from a first fastening point 40 on the loading platform 29 via a first guide means 41 on the loading platform 29, substantially parallel to the second support arm 25 to the guide means 23 and the fastening point 39 on the first support arm 20 and further substantially parallel to the support arm 25 and via a second guide means 42 on the loading platform 29 back to a second fastening point 43 on the loading platform.
  • the positive guide means 32 and 38 By means of the positive guide means 32 and 38 one can ensure that with every angular movement of the first support arm 20 relative to the hoist carriage 14 one gets an equivalent angular movement of the second support arm 25 relative to the support arm 20 together with an equivalent angular movement of the loading platform 29 relative to the support arm 25. In this way one can ensure that, at the same time as the third vertical axis 28a of the loading platform 29 moves horizontally at right angles to the longitudinal direction of the ship, the loading platform 29 is moved in an intended fore-and-aft position displaced precisely parallel between the said inner and the said outer position.
  • a locking member 44 for mechanically locking together the two loading platforms 29 of the hoist carriages 14 and 15, so that the loading platforms can be moved jointly, towards and away from the two positions which are illustrated in Fig. 1 as well as towards and away from different vertical positions within the hoist shaft 11.
  • the two hoist carriages 14 and 15 and associated loading platforms can be moved jointly and in a correspondingly locked manner relative to each other, for corresponding linear movement and at corresponding speed, by means of a common control of the hydraulic control circuits for the two hoist carriages.
  • a common control of the hydraulic control circuits for the two hoist carriages By this one can for example handle a relatively large unit of freight jointly by the two hoist carriages and their associated loading platforms.
  • the support arms 20 and 25 in addition to the swinging movement from and to a posiion in the hoist shaft to and from a position outside the side of the ship can also be swung in an opposite direction from and to the position in the hoist shaft to and from a position further inwards in the ship.
  • the freight on the loading platform can also be transported to a certain extent horizontally into the ship, where this is necessary.
  • the platform is moved in a deviating direction from said fore-and-aft position, for example 90° relative to the longitudinal direction of the ship, that is to say from the fore-and-aft direction to the transverse direction.
  • this can be especially of significance on transportation internally in the ship.
