Description

Known vessels for the transport of heterogeneous goods with plug-in elastic containers. However, the use of elastic containers in known vessels did not solve the problem of replacing one type of cargo with another. A feature of the proposed vessel is that the elastic containers are made in the form of shells, supported on the internal surfaces of the hold. The shells are folded into an envelope and rolled into a bag when replacing one load with another. Using a flexible ribbon, a rolling drum is attached to the lower nasal edge of the shell, which, when it moves to the aft bulkhead, winds the shell folded into the envelope, and when it moves in the opposite direction, winds it. The drum is moved by means of a mechanical drive, for example an electric motor (which is mounted on the vessel), through a cable-blocking system. This difference provides an increase in the tonnage capacity of the vessel, reduces the stress in the elastic tank, and accelerates the process of preparing the vessel for loading.

To simplify the design of the drive and improve the operating conditions, the drum for winding the tank is equipped with an independent drive and mounted on a trolley that can be moved along the floor of the hold or along rail tracks laid along the cargo hold coaming.

In addition, in order to reduce the size of the hulls, the vessel is made with containers installed in pairs in the hold.

FIG. Figure 1 shows a free tank fixed in hangers; in fig. 2-capacity wound on a rolling drum; in fig. 3 — a container filled with a liquid load, and the carriage on which the drum is wrapped around the container is in the extreme position; in fig. 4 - a container, folded on the floor of the hold, wound on the drum of the trolley, when it is moved along the rail track of the cargo hold coamings towards the stern; in fig. 5-capacity, wound on

No. 150023- 2 drum carts and closed housing; in fig. 6 - pairwise placement of tanks in the ship's hold.

Option / (Fig. 1 and Fig. 2) implies the use of a crushing drum to wind the container.

The elastic capacitance / is connected to the katuchm by means of a flexible tape 2 by a drum 3, which is driven from an electric motor (not shown) through driving drums 4 two winches and cables 5 with blocks 6.

The presence of two winches regulates the rolling of the drum 3 strictly along the hold. The length of the drum is selected taking into account the width of the floor of the hold and the width of the package into which the container is folded.

The container is connected by means of a flexible hose 7 to the cargo main line of the vessel, through which it is loaded and unloaded.

As the container is released from the load, it is suspended on the suspensions 8 along the four edges, which prevents the formation of folds on it.

The fully released container is laid on the floor of the hold and wound on the rolling drum 3, which is fixed at the aft bulkhead of the hold and closed by a protective casing 9 (in the drawing, the cover is retracted on the bulkheads). Store ts capacity at the hold wall of the hold.

The unwinding of the container and its preparation for receiving the cargo is carried out in reverse order.

Variant // (Fig. 3) with a drum carriage moving along the hold floor.

The cart 10 is a low portal on four wheels 11, which move along a floor. A reel 12 is installed in the sub-holders on the side frames of the portal, to which elastic capacity 14 is connected with a flexible tape 13.

The length of the portal is selected depending on the width of the bag into which the container is folded.

The carriage and drum rotation are carried out by independent drives, which can be manual or mechanical, mounted on the carriage and can be controlled both remotely and from the inside of the hold. All subsequent operations, both with the release and with the elastic capacity wound on the drum, are the same as indicated in the first embodiment.

A variant /// with an upper drum carriage moving along rails along the cargo hold coamings. Trolley 15 is a bridge farm on four wheels 16 for driving on rails J7 mounted on the longitudinal guides of the coaming of a cargo hold. A reel 18 is installed in the sub-holders on the side frames of the truss, with which an elastic capacity 20 is connected with a flexible tape 19. The container bound on the drum is covered by a casing 21.

The length of the farm corresponds to the width of the hold. The width of the package into which the elastic container is folded must be somewhat less than the length of the working part of the drum of the trolley.

The carriage movement along the hold and the rotation of the drum are carried out on the carriage by independent drives, which can be manual or mechanical.

All subsequent operations, both of release and cleaning of an elastic tank, are similar to the first and second variants. Along with the installation of one tank in each hold, it is also planned to pair the next row of tanks 22 and 23 (Fig. 6) that are in contact with each other along the diametrical plane. the vessel.
