COMPLEX MAINLY USED FOR RAISING OF THE SUNK OBJECTS Russian patent published in 2004 - IPC

FIELD: devices for raising of the sunk objects and ship-raising.

SUBSTANCE: the invention is dealt with a complex predominary used for raising the sunk objects. The complex contains: a surface ship of a catamaran type with a longitudinal frame rigidly fixed on it, the above-deck deckhouses, power hoisting winches with reinforced cables, and also at least one suspended pontoon. On the longitudinal frame there is a telescopic boom with a suspended hook on its end and a reversible electric winch for this boom motion with the help of the chain cable above the nose deck and its moving forwards beyond the limits of the latter. The suspended pontoon has a built-in along its center through channel and located in its upper and bottom parts holes supplied with valves. At that the channel is made with a tong-type grab fixed on its upper end for linking a pontoon with a force chain cable passing through this channel. The indicated valves of the upper and bottom holes are fused among themselves with a capability of simultaneously opening and in series shutting of these holes. At that for each suspended pontoon the complex is provided with four auxiliary electric winches with auxiliary cables fixed above recesses made in the inner sides of floaters of a catamaran. At that the cables ends have grabs to catch lugs of the suspended pontoons. In the recesses there are fixed guide rollers for the auxiliary cables having on their ends cleaning cloth grabs for lugs fixed on a surface of the upper halves of the suspended pontoons. Such realization of the complex expands its functional capabilities and expedites the work on raising different sunk objects.

EFFECT: the invention allows to expand the complex functional capabilities and to expedite the work on raising different sunk objects.
