(5A) SHIP DAY

one

This invention relates to shipbuilding, in particular to ship ga.

Famous ship gangway, containing a flight of stairs with a fence, rollers mounted on the lower end of a flight of stairs, to which is attached a cable connected to a lifting mechanism installed on a vessel, as well as a gripping unit located at the top of the flight of stairs and interacting with the counter element fixed on the ship 1.

A disadvantage of the known convergence is the possibility of an emergency situation during its operation.

The purpose of the invention is to ensure the safe operation of the gangway in the pitching conditions of the vessel.

To achieve the goal in a ship's gangway containing a flight of stairs with a fence, rollers mounted at the lower end of the flight of stairs to which is attached a cable connected to a lifting mechanism installed on the vessel, as well as a gripping unit located at the top of the flight of stairs and interacting with the counter element fixed on the vessel, the gripping unit includes guides fixed along the flight of stairs, and a hook with a stopper attached to the upper end of the flight of stairs, the counter element of the vessel is made in the form of a roller interacting with the said guides and a hook, and the enclosure contains a lattice arch, the front part of which is covered with an elastic net.

FIG. 1 shows the lower part of the gangway; in fig. 2 - the upper part of the gangway; in fig. 3 - gathering assembly, general view;

10 in FIG. 4 - a fastening unit for the lower end of the gangway on the deck of a low-profile ship; in fig. 5 - gangway position when disembarking people.

(5 The lower and upper parts of the gangway contain bowstrings 1 with steps 2 of a flight of stairs. The lower part of the gangway is equipped with rollers 3, a lattice fence 4 at the top and sides of the gangway and an elastic mesh 5 that can be made

20 for example, from rubber harnesses covering the end. From one side of the lower part of the gangway near its end in the crib fencing, an opening 6 is equipped, the dimensions of which are chosen from the condition of passage through

him man. The upper part is equipped with runners in the form of runners 7, hook hooks 8, a stopper 9 and rail guard 10. For fastening between each other, the upper and lower gangways are equipped with fasteners II and 12, which can be made, for example, by bolts.

The deck of a low-borne vessel A is equipped with guides 13 for the lower end skating rink rollers, an emphasis 14 and a block 15. A cable 16 is fastened to the lower end of the gangway, wound through an opening 17 of the abutment 14 and block 15 on a spire or winch.

The high-breasted boat B is equipped with a roller 18.

Similar is used as follows.

Proceeding from the difference in height of the sides of the two vessels and the magnitude of mutual vertical displacements, using the fastening nodes 11 and 12, set the desired length of the gangway, the low-border vessel A is moored to the high-breasted vessel B. Skhodnya runner 7 is placed on roller 18. block 15, with the help of a winch or a spike, is pulled to the stop 14. In this position, the lower end of the gangway is fixed and has minimal (only rotational) movements relative to the deck of the low-profile ship A. Vertical reciprocal movements of ships They compensate by rolling roller 18 on the roller 18. Through port 6, people (for example, an emergency party) enter the gangway, transferring to a high-breasted vessel B. Tail 16 grass, remove the rollers from the stop 14 until they bring 8 roller 18. In this position (fig. 5), the gangway is fixed by a stopper 9. Now mutual vertical movements are compensated by rolling the roller 3 on the deck of a low-boring vessel along rails 13. People come to the deck of high-boring vessel B from the upper end of the gangway fixed on roller 18 and having o minimal (only rotational) movements relative to vessel B.

The transfer of people from vessel B to vessel A is carried out in the reverse order.

In the event of an unexpected, very large divergence of vessels along the vertical and landing of hooks 8 on roller 18. To prevent rupture or disruption of hooks 8, rollers 3, slid up on stop 14, are detached from the deck of ship L, pulled by cable 16. For this, the winch should have a friction clutch or a relatively low power to rotate with a high tension of the cable 16.

The ship gangway provides boarding and desparing of people through fixed, relative to the deck of ships, the ends of the gangway, thereby increasing the convenience and safety of transplanting people into the sea.
