Description

(54) DEVICE FOR RE-SHIPMENT FROM SHIP OF LARGE CARGO CAPACITIES

vessel with cargo tanks to the load gripping devices of cargo carriages 3 moving along the overpass. The lock chamber is equipped with a gate 4.

The overpass connects the lock chamber with the shore and has the necessary structural rigidity, which ensures the movement of all cargo tanks of the ship party with cargo. The overpass is installed horizontally. The bridge struts can be distinguished by the type of bridge trusses, located on supports (by bulls), and according to the type of mounted bridges. The height of the overpass horizon depends on the topography of the coast and the dimensions of the cargo tank. The part of the overpass located above the airlock chamber must ensure the strength of the chamber against lateral expansion efforts when filling the chamber with water.

The waterproof flap 5 of the chamber is located on the side wall of the sluice chamber facing the coastline and provides the water tightness and rigidity of the chamber in the closed state when the chamber is filled with water, and also freely passes cargo tanks through the sluice wall in the open position.

Ramp 6 is located under the overpass on the beach and is a concrete platform. The angle should be minimal. It ensures that the platform of the trailer rotates to the extent that the weight of the cargo tank is fully taken up by the platform, which, in terms of the inclination, goes to the horizontal plane.

The cargo trolley 3 is long to have a load gripping device, which provides for gripping and uncoupling the cargo tank from above, and have a mechanism for moving it with the cargo tank with cargo on the overpass. The trolley movement mechanism can be mounted both on and outside the cargo trolley, but connected with its cables.

The pump compartment 7 of the sluice chamber 1 is equipped with nasrs, which should ensure both the filling of the chamber and, if necessary, the lowering of the water level in it. The number of pumps is determined from the required vertical speed of the vessel in the chamber.

The airlock chamber 1 is equipped with conduits both for pumping water into it, for emptying water from it, and for protecting the chamber from washing out the soil near it. The large cargo tanks 8 are reloaded from the vessel 9, on which they are rammed.

The overloading of large cargo tanks from the vessel is carried out in a skinny manner. Vessel 9c cargo ships. 8 enters the sluice chamber 1 and is fixed in it so that the cargo tanks 8 are located under the load handling devices of the cargo trolley 3 (Fig. 2), then the gates 4 of the sluice chamber are closed and water is pumped into the chamber. The water level in the lock chamber is increased, raising the vessel to the load gripping device of the trolley 3 until it captures the cargo tanks (Fig. 3). Thereafter, water from the chamber is discharged by gravity. The vessel, being lowered, is simultaneously freed from the cargo tanks. At the same time, the valve 5 in the wall of the sluice chamber is waterproof and waterproof. If the height of the ship’s side does not allow the cargo tank to freely exit the lock chamber with equal levels of water surface in the lock chamber and beyond, then the water level in the chamber is lowered (Fig. 4).

After the waterproof shutter 5 is lowered, freeing the opening in the wall of the sluice chamber, the cargo carriage 3, together with the cargo tank, moves along the overpass 2 from the sluice chamber.

The loading of the cargo tank onto the vessel is carried out in reverse order. The cargo tank is reloaded from the ramp onto the platform of the heavy-duty trailer using ramp 6 located under the ramp on the beach (Fig. 6). .

After cargo capacity 8 on overpass 2 approached ramp 6; The platform of the trailer is fed to the inclined ramp and is installed exactly below the horizontal capacity, after which the platform begins to move together to the cargo tank with equal horizontal speeds. Lift up, the platform takes the cargo capacity to itself. Pullout of the cargo tank from the load gripping device of the trolley took place. The horizontal plane of the ramp.
