Description

one

The invention relates to the field of hoisting-and-transport machinery, namely, the transshipment devices placed on the ship’s deck, designed primarily for loading and unloading ships in rough seas, for example, in the open sea.

Such kind of devices are known, which contain a main slewing crane with a tilting mechanism, the hook suspension cable of which interacts with the rope of the polyspast tracker system of the auxiliary noiBOpOTHoro crane.

With the reduction of repentance. cargo by performing overloading operations by means of overloading, in the proposed device an auxiliary swivel. To | wound is made with a hoist on the pulley system of its tracking system, one end of which is wound on the drum of an additional winch of this crane, and the second the crane.

It is also envisaged that the auxiliary cable hoist rope can be equipped with a hook suspension, and both the auxiliary crane and the main crane are mounted on a common turntable mounted on the deck of the vessel.

This allows both, if necessary, to be used (split separately.

The drawing schematically shows the proposed installation.

It is mounted on the forehead of the vessel 1, from which the vessel 2 is being loaded.

Column 3 carries the turntable 4; on the latter, in turn, are installed rotary KipaHbi 5 vi 6, the main and auxiliary respectively.

The crane 5 is equipped with a lifting mechanism 7, the rope 8 of which carries the hook suspension 9. On the boom 10 of the crane 6, a tracking system is mounted, the pneumatic cylinder 11 of which is connected to the crossheads carrying the cams of the polyspasts 12 and / 3.

The rope 14 of the polyspast 12 at one end is provided with a hook 15 for attachment to the vessel 2, and the second end is wound on the drum of the winch 16.

The rope 17 of the polyspast 13 is wound on the drum of the lifting mechanism 18 and loosely attached to the hook suspension 9.

In the position shown in the drawing, the movement of the rod from the tank, ship / to the ship 2 is carried out by twisting it with ropes 8 - 17 with the combined operation of the lifting mechanisms 7 and 18, cranes 5 and respectively.

The difference in the levels of the decks of the ships 1E2, which may arise as a result of waves, is compensated by the work of the tracking system, the tackles 12 and 13 of which change their length in accordance with the movement of the ships.

In order to eliminate interference in the operation, when raising and lowering the K | tiller suspension 9 on ships 1 and 2, the ropes 8 and 17 are weakened accordingly.

Suspension mount 9 single1V | remenno on the ropes 8 and 17 reduces its swinging, which is especially important for work on waves at sea.

For separate operation of cranes 5 and 5, the last system of the latter is disconnected. Qaiat 77 is disconnected from the suspension 9 and provided with a corresponding hook suspension.

If necessary, the platform 4 is deployed so that both cranes can operate with one side.
