Definitions

  • Such deck cranes are for example off WO 97/28042 known. They are attached to ships and serve for loading and unloading the ships or for moving loads on the ships. Furthermore, these deck cranes can also be used for launching and picking up dinghies. The arms are each moved by tilting and retracting the piston of a hydraulic cylinder up and down. Between their periods of use, the deck cranes take a rest or standby position, in which the boom for safety and space reasons are held by the hydraulic cylinder in an upper position. In this standby position, the deck cranes often remain for long periods of time. Due to the inevitable leakage in the hydraulic cylinder, it must always be readjusted to compensate for the leakage and to keep the boom in its upper position.
  • this object is achieved in a deck crane of the type mentioned above in that a strut is hinged at its first end to the boom and at its second end to the crane housing and in its longitudinal direction one behind the other has a first and a second strut member by means of a pregnantgelenks are hinged together and with the second part of the fluid cylinder, the intermediate joint of the fluid cylinder is laterally displaceable while traversing a trajectory that traverses a running through the two end joints of the strut straight, the fluid cylinder is adapted to the intermediate joint on a first Side of the line to move by a predetermined first measure for rocking the boom and on the opposite second side of the straight line by a predetermined second degree, and that a stop is arranged, which blocks the intermediate joint at the end of the movement path on the second side of the straight line.
  • the length of the trajectory is so great that the boom can go through its necessary for the operation rocking angle.
  • the trajectory is limited by a stop that locks the intermediate joint at the local end of the trajectory.
  • the intermediate joint is pressed after crossing the straight line by the weight of the boom in the direction of this blockage, so that the boom blocks when the lock becomes effective by its own weight in its standby position itself.
  • the fluid in the fluid cylinder is therefore only necessary here to guide the boom into the standby position or to guide the intermediate joint to its blocking on this other, second side of the movement path. In the standby position itself, the fluid due to the blocking of the intermediate joint without function and therefore a leakage occurring in the fluid cylinder without influence.
  • the first part of the fluid cylinder forms the stop and the second part of the fluid cylinder is in its direction of movement to the first part, when the intermediate joint on the second side of the straight line is shifted by the second degree.
  • the boom on a telescopic part As a result, a more distant storage position can be used for the dinghy or a dinghy be taken from a larger lateral distance from the ship.
  • a deck crane according to the invention has a device for applying a constant tension on the hoisting rope, so that the load can be pulled with its rope receiving part with constant tension against the boom head and can be fixed on this with constant tension via frictional engagement.
  • the contact part provided for the frictional engagement on the jib head particularly preferably has a mobile device braked about two horizontal axes. Due to the constant tension applied to the load, this returns from a laterally deflected position by gravity back into the vertical under the boom head. If the load is fixed to the boom via frictional engagement, the magnitude of the applied tensile force can be used to set the magnitude of the frictional force between the load and the boom head.
  • the deck crane on a hoist winch for winding the hoist rope which is switchable to Seegangs Avenue.
  • the hoist rope is always taut.
  • the deck crane also has a leash for securing the deployment and / or picking up a dinghy while the ship is in operation.
  • the position of the dinghy relative to the ship can be stabilized in this way.
  • a deck crane 1 comprises a crane housing 2, a boom 3, a fluid cylinder 4 and a strut 5.
  • the crane housing 2 is mounted on the deck 6 of a ship 7. It has a vertical pivot axis 8 about which the crane housing 2 is rotatable or pivotable.
  • an end 9 of the boom 3 is rotatably mounted about a horizontal axis 10, so that the boom 3 can be moved up and down, d. H. Can perform rocking movements.
  • the strut 5 At a predetermined distance to the articulation of the boom 3 to the crane housing 2 extends between them, the strut 5. It is articulated at its one end 11 to the boom 3 and at its other end 12 to the crane housing 2. In its longitudinal direction, it is divided into two, d. H. it has in its longitudinal direction two successive strut parts 13, 14. The two strut parts 13, 14 are connected by means of an intermediate joint 15 hinged together. The respective other ends of the two strut parts 13, 14 form the ends 11, 12 of the strut 5 and are articulated to the boom 3 and to the crane housing 2.
  • the end joints 11, 12 and the intermediate joint 15 each have horizontal axes of rotation.
  • the fluid cylinder 4 has a cylinder tube 16 and a displaceable in this piston with a rod 17.
  • the cylinder tube 16 is articulated on the crane housing 2 and the piston with the rod 17 on the intermediate joint 15.
  • the fluid cylinder 4 is preferably a hydraulic cylinder.
  • the intermediate joint 15 is laterally displaceable by the fluid cylinder 4. In this case, the trajectory of the intermediate joint 15 traverses a through the two end joints 11, 12 of the strut extending straight line.
  • the two strut parts 13, 14 lie one behind the other on the straight line, ie the strut 5 assumes its erected position and the boom 3 reaches its uppermost position. In every other position of the intermediate joint 15, the strut 5 has a kink.
  • the intermediate joint 15 is also to the opposite other side of the line, in the embodiment shown in the figures to the crane housing side, by a predetermined amount movable. This measure is predetermined by a stop (not shown) which locks the intermediate joint 15 on this other, second side of the straight line after a predetermined trajectory length.
  • the weight of the boom 3 presses the intermediate joint 15 due to the buckling of the strut 5 against this barrier.
  • the boom 3 thus blocks itself in this position.
  • This position is the ready position of the deck crane 1. Due to the self-blockade in the above-described end position of the fluid cylinder 4, the fluid is out of order. Even with a longer stay of the deck crane 1 in its standby position, the position of the boom 3 is maintained. Leakages in the fluid cylinder 4 have no influence on the ready position. A readjustment or adjustment of the fluid cylinder 4 is not necessary.
  • a jib head 18 mounted at the free end of the boom 3 is a jib head 18, which is rotatable about two horizontal axes 19A, 19B, one of which is parallel to the jib axis 10 between jib 3 and crane body 2, and 90 ° about the other staggered.
  • the boom head 18 has a downwardly facing outlet opening 20 for a hoist rope 21.
  • This outlet opening 20 is enclosed by a conical outer surface 22 which is formed to rest against a correspondingly shaped funnel-shaped inner surface 23 of a cable receiving part 24 of the dinghy 25.
  • a device 26 for securing the Hubseilendes.
  • a hoist winch 27 is mounted on a hoist rope 21 is wound or from the hoist rope 21 can be handled. From the hoist winch 27 from the hoist rope 21 extends along the top of the boom 3 to the boom head 18 and then through it. From the outlet opening 20, the hoist rope 21 exits vertically downwards.
  • the boom head 18 is provided with a rotatable member 28 with drive.
  • This rotatable part 28 surrounds the outlet opening 20 for the hoist rope 21 and has the abutment or outer surface 22, which is provided for frictional engagement with the corresponding surface 23 in the cable receiving part 24 of the load or the dinghy 25.
  • the rotatable member 28 can be rotated 360 °, so that dinghies 25 can be picked up from any position to the ship 7 or deposited in any direction.
  • the dinghy 25 is shown in its storage position on the ship deck 6. Due to the pivoting of the crane housing 2 and / or the rotatable member 28 on the boom head 18, the dinghy 25 can be discontinued so that the deck crane 1 is in front of the bow 29 or behind the stern of the dinghy 25. Thus, the entire longitudinal side 30 of the dinghy 25 is free to remove or climb. Secure access to the dinghy 25 is thus ensured.
  • the hoist winch 27 is switchable to Seegangs scenic so that up and down movements of a dinghy 25 are compensated as a result of wave movements in the unwound rope length and thus the free rope length between boom head 18 and dinghy 25 is always kept taut.
  • the hoist winch 27 has a device for applying a constant tension on the hoist rope 21.
  • the hoist winch 27 has a device for applying a constant tension on the hoist rope 21.
  • At the dinghy 25 is thus pulled vertically upwards with a predetermined tension. In lateral, horizontal deflections of the dinghy 25 this is therefore always brought back by its own weight in the vertical position under the boom head 18. Pendulum movements of the dinghy 25 are thus greatly reduced.
  • the boom 3 may be telescopic to absorb or settle the loads even in the greatest possible distance from the crane housing 2 or ship 7 and also to achieve the shortest possible adapted length of the boom 3 in the ready position.
