Abstract

The invention relates to shipbuilding, in particular, to dock-type ship designs. The purpose of the invention is to improve cargo handling by the docking method. The pontoon-type barge dock has hull 1, a feeding superstructure 2 and a wheelhouse with a control post 3, side towers 4 in the bow of the vessel and a bow ramp 8. Towers 4 in the lower part have a wedge-shaped shape with a wedge angle of 20-30 ° & to the vertical and connected to the housing 1 by means of hinges 7 and the actuator. When loading floating objects of large width onto the barge in a submerged state, the towers 4 are deflected outward by means of a drive, which increases the width of the passage in the bow and improves the stability of the barge. 3 il.

The invention relates to shipbuilding, and specifically to the construction of barges docks.

A barge dock is known, including a pontoon-type hull with a feed superstructure permeable in the lower part with a wheelhouse and a control post, two bow mounted along the sides of the turret and a bow ramp.

However, when receiving cargo more than 22 m wide by the docking method, the nose towers are dismantled, which is associated with low labor productivity and reduced stability of the barge in the submerged state.

The purpose of the invention is to improve cargo handling by the docking of the barge dock.

FIG. 1 schematically shows a barge-dock in a transport state, a view of the nose with an open ramp; in Fig. 2, a bridging dock during a cargo operation, a view of a nose; in FIG. 3, view A in FIG.

The barge dock includes a pontoon-type hull 1 with a aft superstructure 2 of a cabin and a post of control 3 and a bow along the sides of the tower 4 with a post of 5 watchmen. The towers 4 are connected to the case 1 of the barge by the hinges 6 and the oil seals 7 of the known construction coaxial with them and in the transport position are closed with a ramp 8. The towers 4 have wedge surfaces 9 at an angle of 20-30 to the vertical on the inner sides and notches on the outer sides 10, where hydraulic cylinders 12 are fixed on hinges 11. Case 1 also has notches 13 on the sides of the nose, where hydraulic cylinders 12 and cargo deck 15 are fixed on hinges 14. control leniem.

The dock barge is operated as follows.

When the cargo is loaded onto the cargo deck 15, the width is less than the distance between the vertical inner walls of the new towers 4, the latter remain in an upright position, as shown in FIG. 1, and the cargo is brought onto deck 15 by known methods, with the hull 1 of the dock barge or the submerged position normal, after which the ramp 8 covers the bow of the dock barge. When the cargo is loaded onto the cargo deck 15, the greater distance between the vertical sides of the nose towers 4, the ramp 8 is opened, the working cylinders 12 are supplied with working fluid so that their rods are retracted while the bow towers 4 are inclined on the outer sides of the hull 1 barges the dock (as shown in FIG. 2), swiveling on the hinges 6 and the oil seals 7, and the hydraulic cylinders 12 coming out of

of their grooves 10 and 13, turning on hinges 11 and 14. When the wedge surfaces 9 are in a vertical position, the rolling cargo rolls over ramp 8 onto the cargo deck 15. For receiving a floating load, the hull 1 of the barge dock is ballast in a known manner to a depth of 0.5 m above the draft (as shown in FIG. 2). At the same time, the nose towers 4 are inclined outward of the housing 1 to 20.

5–30 ° and are capable of passing a floating load of increased width, at the same time significantly increasing the stability of the barge in the submerged state, since they cross the surface of the water. After lifting the floating load, the above operations and the interaction of the parts of the barge is performed in the reverse order. When receiving a floating load using asymmetric ballasting of the barge 5 of the dock, the ramp 8 is opened, the nose towers 4 are rotated in the inclined position shown in FIG. 2 in the manner described above. open top and bottom gate valves, barge dock

0 is ballastised and pripaplivatsya, water enters through the bottom klinetketny valves in the nasal towers 4, the air is forced out of them. When the hull reaches the bottom of the water area (20 m), the towers 4 turn on their

5 hinges 6 and gland tubes 7 using hydraulic cylinders 12 to a horizontal position so as not to interfere with loading floating load, after which the docking barge debalances, the nose tower M 4 is attached to the vertical position, their upper klinetnye valves are closed one by one compressed gas is supplied from the pipe-glands 7, the water from the towers 4 is squeezed out through the bottom klinetnye

The 5 valves, which, after the discharge of water, are closed, the supply of compressed gas is stopped, the hydraulic cylinders 12 are placed on known hydraulic locks, and the ramp 8 is closed. In the absence of mooring operations nasal

0 towers 4 can be fixed in the position as in FIG. 2 for the entire flight in order to receive cargo not only of increased width, but also of increased length. Rods of hydraulic cylinders 12 can be supplied

5 elastic oil resistant cuffs.

The operation of the proposed barge dock leads to a significant improvement in the performance of cargo operations, since the demon stage doesn’t disappear - the installation of the nose towers using manual labor and port cranes. The operation of the proposed dock increases its stability in a submerged state when receiving wide loads since the nose towers during cargo operations are not dismantled, they are only tilted by mechanisms and cross the water surface in an inclined position in the submerged state of the dock
