Definitions

  • the invention relates to a locking of a folding barge according to the preamble of claim 1.
  • Hydraulic cylinders which are arranged transversely in the area of both ends of the ship and which, like their piston rods, engage on the two foldable parts of the ship via joints are commonly used to open and close folding barges, especially those of a larger type. Accordingly, these cylinders must be fed via articulated pipe connections or hose lines. This, as well as the seals inside the cylinder, can lead to leaks, which means that there is a risk that the bulkhead will open unintentionally, even if only by a small amount, and lose the load in the form of a bulk material. For this reason, in addition to the hydraulic actuation system, a mechanical lock is provided which is able to keep the barge closed in the event of a total or only partial failure of the hydraulic actuation system.
  • Such a mechanical lock is known for example from DE-OS 1 957 156 and DD-PS 85 520 in the form that hook bearings and cross bolts on arms, trestles or the like arranged in the region or below the hydraulic cylinders for the folding movement, for example in Area of the middle of the ship.
  • Such support elements require a sufficiently strong anchoring in the hull, for which - as in principle also for the points of attack of the hydraulic cylinders - reinforcing internals are required. Because of their arrangement under the hydraulic cylinders, the locking means in question are difficult to access, especially since they are generally flooded even when the ship is unloaded.
  • the object of the invention is to remedy this, i.e. to design a lock in accordance with the generic term in such a way that reinforcements, as well as own arms, trestles or the like, which are added to the points of attack of the hydraulic cylinders, are unnecessary and that the lock is at least temporarily accessible without special measures being required.
  • the arrangement of the lock directly on the respective hydraulic cylinder makes it possible to get by without additional stiffening fixtures and arms, trestles or the like.
  • the locking with the hydraulic cylinder occurs at such a level that it comes to rest on the water surface when the ship is unloaded. Of course, it is not covered by the hydraulic cylinder, so that it can be easily checked and serviced.
  • the two ship parts 2 and 4 of the folding barge shown which can be folded with respect to one another are connected to one another above the deck surface 6 by joints 8.
  • the folding barge contains a loading space 10 which is delimited on the underside by floor surfaces 12 and 14 inclined in each case in one of the two foldable ship parts 2 and 4. If the two ship swings steep 2 and 4 apart in the sense of the double arrow 16, then the bulk material located in the cargo hold 10 can emerge downward between the floor surfaces 12 and 14.
  • the folding barge is opened and closed by mutually pivoting the two ship parts 2 and 4 by means of transversely arranged hydraulic cylinders 18, which act on the two ship parts themselves or via their piston rods 20. More precisely, the two ship parts 2 and 4 have for this purpose bearing blocks 22 and 24, which form joints 26 and 28 as points of attack. To introduce the forces, the hull has reinforcements 30 and 32 at the same locations. At the joints 26, the piston rod 20 engages via an attached head 34 such that the axes of the piston rod and the joint intersect.
  • the cylinders 18 are supplied via a high-pressure hose 36. So far the arrangement is conventional.
  • each hook 38 has an inclined cam surface 46 with which it can slide onto the relevant cross bolts 42 when the piston rod 20 is retracted.
  • an eye 48 on the top of each hook engages as shown in FIG. 1 a pull rod 50, which carries a thread 52 at its other end.
  • the pull rod 50 protrudes through a bushing 54, which is pivotably mounted in a bearing block 56 on the deck surface 6 of the relevant ship part 2 about an axis parallel to that of the joint 26.
  • a nut 58 with a handwheel 60 on the thread 52 which shortens the tie rod 50 and the hook 38 can be raised, while on the other hand it can also leave the drawn locking position by itself. So that the hook 38 cannot drop too far when the piston rod is extended, so that it can no longer slide onto the associated cross members 42, the pull rod 50 carries a stop ring 62 at a suitable location above the nut 58.
  • the water level 64 is as shown below the cylinder 18 and thus also the locking means (hook 38 and cross bolt 42), so that the locking means can be easily checked and serviced.
  • the hooks 38 can be actuated here instead of manually via small hydraulic cylinders 70.
  • the rear end of the cylinders 70 is hinged to the bearing block 22, and its piston rod 72 engages the hook via a joint 74.
  • the cylinders 70 can be single-acting, only to lift the hook, while the weight of the hook finds its way back into the locking position shown, in which the piston rod 72 is fully extended.
