Description

FIELD OF THE INVENTION The invention relates to shipbuilding, in particular, to loading and unloading devices for transferring cargo in open sea conditions.

A device is known for transferring cargoes from one vessel to another under open sea conditions, comprising a column, an arrow, a counterweight, a cargo and track systems with cargo and auxiliary winches and a cable assembly system 1.

However, such a device does not provide a smooth and unstressed transfer of cargo from one vessel to another in rough seas.

The purpose of the invention is to provide a smooth and unstressed transfer of cargo.

For this, the device contains a crosspiece in which guides are made, a traverse with a block and a movable load, the crossbar being rigidly fixed on the column, an arrow hingedly mounted on the crosspiece, in the guides of which the traverse is movably mounted with a block through which a cable connected one with the end of the boom and the other with the counterweight, and the movable cargo carriage connected to the cargo system is mounted on the boom.

In order to provide the minimum required tension of the cables of the follow system, the auxiliary winch is connected by a wire system with a cross beam.

For damping the counterweight, the device is provided with a shock absorber mounted in the column under the counterweight.

FIG. 1 shows a schematic diagram of the device before, a general view; in fig. 2 - kinematic diagram of the device.

The device contains a column / on which the crosspiece 2 is rigidly fixed, on which, in turn, an arrow 3, a counterweight 4, a cargo winch 5 connected by a troso-block system 6 with a load 7, mounted by means of a movable cargo carriage 8 mounted on the boom 3, the winch 9 of the movement of the freight carriage 8, associated with the last and the boom side 3 of the troso-block system 10.

The device also comprises a yoke with a freely seated block 12, which is movably mounted in the guiding slots 13 made in the crossings, through the block 12 a cable 14 is connected, connected at one end with the boom side 3, and at the other end with the protractor 4.

Winches 5 and 9 are mounted on a platform 15 rigidly connected to the column. Winches 16 and 17 were also installed on the platform / 5, and were connected to the deck of the receiving vessel 18 with troso-block systems 19 and 20, and

an auxiliary winch 21, connected by a trosoai system 22 with a cross beam 11, a shock absorber 23 is mounted under the counterweight 4.

The device works in the following way.

In the stowed position, the boom 3 of the device is in position I (see Fig. 1), and the counterweight 4 is in the lower end position. In preparation for non-unloading operations by the winch 21 by means of the cable system 22, the yoke // is lowered down. Arrow 3 at the same time takes the half-son II. Winches 16 and 17 give the slack to the cables 19 and 20 and after attaching them to the deck of the carrying vessel 18, this slack is chosen, the arrow 3 is brought to the horizontal position (III). The winch 21 lifts the yoke 11, while changing the angle of inclination of the cable 14 with respect to the boom 5. This achieves the minimum: good running tension in the cables 19 and 20 of the follower system, which is slightly higher than the weight of the load 7.

Since the weight of load 7 is mounted in the following cables 19 and 20 of HpeBbiujaeT, the boom 3 tends to rise to its upper position, resulting in a vertical movement of the deck of the welded ship 18, but the boom is completely repeated. The constant distance between the boom 3 hole and, consequently, the load 7 and the deck of the receiving vessel 18 is ensured.

The winch 9 of the freight carriage 8 is supplied to the axis of rotation of the boom 3. At this point, the swinging amplitude of the cargo carriage relative to the deck of the transmitting vessel is almost zero.

After securing and lifting the load 7, the freight carriage 5 is transferred to the boom point 5 with the help of a winch 9.

decks of the receiving vessel. As a result, the amplitudes of the load swing 7 and the deck of the host vessel 18 are equal, and therefore the landing (removal) is unstressed

cargo in a given area of the deck of the receiving vessel 18.

The proposed device allows for smooth and unstressed transfer of cargo from one vessel to another under volpeni kor conditions.
