Abstract

FIELD: transport.

SUBSTANCE: invention relates to ship building, particularly to shipboard cranes. Proposed re-loader comprises hulls of two discarded submarine, at least two hulls jointed in T-like way or arranged parallel to each other and connected by additional elements, and at least one load-lifting device. At least one aforesaid hull is provided with fendering protection and mooring arrangements on hull both sides. Additional construction elements are arranged under water and/or on water surface and represent collapsible articulated members that can turn to contact aforesaid hulls. Load-lifting device can be represented by jib crane, gantry crane or bridge crane with jibs. Floating re-loader is equipped with power plant, propulsion units, ballast system and stake-pillars.

EFFECT: higher efficiency or reloading cargoes due to reduced distance between ship with no load-lifting units.

Description

Technical field

The invention relates to shipbuilding, in particular to ship cranes, and can be used for loading and unloading operations afloat.

State of the art

Known mooring reloading system for containers, containing a mooring crane with a cantilevered span and a cargo trolley, a gantry crane with a cantilevered span and a cargo trolley [1] (document "A" No. 95116047, class B65G 67/60, publication 27.08.1997 g .). The disadvantages of this system include low system performance when reloading from ship to ship, for example, from sea to river, and the need to use the berth area.

Known floating berth terminal containing boats equipped with mooring devices and loading and unloading mechanisms, each boat is made in the form of a vessel containing a hull with cargo holds, having a bottom, side and deck floors and made with a superstructure, the upper deck floor of which is made in full length of the vessel [2] (document “A” No. 96118091, class B63B 35/44, publication date 01/20/1998). The disadvantages of this berth terminal include the technical complexity of the formation of a transport system for loading and unloading.

Known closest to the invention is an analogue (prototype) of a floating crane containing a platform, a jib device and a rotation mechanism [3] (document "A" No. 93002343, class .: B66C 23/52, publication date 09/07/1995). The disadvantages of this floating crane include low crane performance when reloading from ship to ship, due to the significant distance between them when they are placed on both sides of the floating crane.

SUMMARY OF THE INVENTION

The aim of the invention is to increase the productivity of loading and unloading operations from ship to ship at the port berth, in the water or at sea (in drift, on the move or anchored) by reducing the distance between ships not equipped with lifting devices.

This goal is achieved by the fact that the floating reloader contains at least two buoyancy (for example, T-shaped) and at least one lifting device, while at least one buoyancy is equipped with crane protection and mooring devices on both sides of it.

Variants of a parallel arrangement of buoyancy and their connection with additional connecting elements located under water and / or above the water are possible. There are options for equipping a floating crane with a lifting device in the form of a jib, gantry or bridge crane with consoles.

There are options for equipping a floating crane with a power plant and propulsors, a ballast system, as well as overhead piles.

As buoyancy it is possible to use decommissioned hulls of submarines.

Options for the implementation of collapsible joints, as well as articulated with the possibility of rotation until the abutment of the sides of the buoyancy.

Information confirming the possibility of carrying out the invention.

The floating crane contains at least two buoyancy 1 interconnected (for example, T-shaped) and at least one lifting device 2, while at least one buoyancy 1 is equipped with crane protection and mooring devices 3 on both sides of it.

The buoyancy 1 is made of metal or reinforced concrete and interconnected by metal connecting elements 4 in such a way that it is possible to arrange vessels 5 on both sides of at least one buoyancy 1.

With a parallel arrangement of buoyancy 1 and connecting elements 4 underwater, it is possible to equip the floating crane with a lifting device 2 in the form of a jib crane 6 or a gantry crane with crane tracks.

When the connecting elements 4 are located above the water, they are made in the form of columns 7 with transverse and longitudinal beams 8, to which at least one overhead crane 9 with consoles 10 is attached, and it is possible to load three vessels or two vessels at the same time while setting up a floating crane at the port berth.

The proposed floating crane provides an increase in the productivity of loading and unloading operations from ship to ship at the port berth, in the water area or at sea (in drift, on the go or at anchor) by reducing the distance between ships not equipped with lifting devices.
