Изобретение относитс к области гидротехнического строительства, а более точно - к причальным устройствам шлюзов и причалов, предназначенным дл швартовки судов.The invention relates to the field of hydraulic engineering, and more specifically to berthing devices of locks and moorings, intended for mooring vessels.

Известен плавучий рым дл швартовки судов , содержащий основной поплавок с верхней кареткой и опорно-ходовой частью, посредством которых рым перемещаетс по рельсовым закладным част м в вертикальном направлении, и причальный крюк 1 .A floating eye for mooring vessels, comprising a main float with an upper carriage and a running gear, by means of which the eye is moved along rail rail parts in the vertical direction, and a mooring hook 1, is known.

Известен также плавучий рым дл швартовки судов, вл ющийс наиболее близким по технической сушлости к предлагаемому, содержащий основной поплавок с верхней кареткой, опорно-ходовой частью и причальным крюком 2.Also known is a floating eye for mooring vessels, which is the closest in technical drying to the one proposed, containing a main float with an upper carriage, a supporting chassis and a mooring hook 2.

Недостатком известных конструкций вл етс возможность зависани или притоплени пришвартованного судна при заклинивании в направл ющих пазах рельсовых закладных частей при попадании в них плавучих тел во врем изменени уровн воды, вследствие чего пришвартованное судно может либо зависнуть над водой, либо притопитьс вместе с pbiMOM.A disadvantage of the known constructions is the possibility of the mooring of a moored vessel when it is jammed in the guide grooves of the rail fixings when floating bodies get into them during a water level change, as a result of which the moored vessel can either hang above the water or be submerged along with the pbiMOM.

Цель предлагаемого изобретени - обеспечение автоматической отшвартовки судна при заклинивании рыма в закладных част х и улу шение эксплуатационных качеств.The purpose of the present invention is to provide automatic unmooring of the vessel when the eye is wedged in the embedded parts and to improve performance.

Достигаетс зто тем, что рым снабжен двум дополнительными поплавками, кинематически св занными рычагом, причем в основном поплавке вьшолнены прорези, размещенные - одна выше ватерлинии, а друга ниже, в которых установлены дополнительные поплавки, This is achieved by the fact that the eye is provided with two additional floats, kinematically connected lever, and the main float is filled with slots, one placed above the waterline, and the other below, in which additional floats are installed,

10 причем причальный крюк снабжен фиксатором, взаимодействующим с рычагом и шарнирно подсоединен к верхней каретке, а на шарнирах причального крюка и фиксатора установлены пружины.10 wherein the mooring hook is provided with a latch interacting with the lever and pivotally connected to the upper carriage, and springs are mounted on the hinges of the mooring hook and the latch.

Claims

The floating eye for vessel mooring consists of the main float 1, in the slots of which poro additional floats are placed - the bottom 2, located below the waterline, and the top 3, located above the waterline. On the axis of the top carriage 4, the mooring hook 5 and the latch 6 are hinged. the hinges of which are mounted spring 7 and 8, as well as the upper guide rollers 9. On the lower carriage 10 there are fixed guide rollers 11. BepxiHie guide rollers 9 and lower 11 form the undercarriage of the eye. Additional floats 2 and 3 are kinematically connected by hinged rods 12 and 13 and, via levers 14, with a latch (lock) 6. The device operates as follows. In the general state, the eye moves vertically in accordance with the change in water level, the mooring hook 5 of the eye is supported on the protrusion of the latch 6, the latch 6 is pressed by the spring 8. The upper additional float 3 is above the water level and supported on the bottom of the front slot, the lower float 2 is below the water level and propped up to the top of the slot. In the case of a seizure of the eye with a moored vessel when the water level drops (Fig. 3) below the base of the float 2, it with its mass through the hinge rod 12 acts on the lever 14, which pushes the latch 6, causes it to turn to the left, and releases the mooring hook 5 from the stop. The hinge bar of the GZ rods does not prevent rotation because its upper fork has an oval slot. Under the action of the force arising in the mooring line of the vessel, the mooring hook 5 rotates around an axis and releases the hook. After detaching the chuck under the action of the spring 7, the mooring hook 5 returns to the working position, and after raising the water level and flooding the float 2, the latch 6 returns to the working position. In the event of a seizure of the eye with a moored vessel when the water level rises (Fig. 4), the upper float 3 pops up and, with its pushing force through the hinge rod 13, acts on the lever 14, pushes the latch 6, causes it to turn to the left and frees the mooring hook 5 from the stop. Rod 12 does not interfere with rotation due to the oval slot in its upper fork. Under the action of the force arising in the ship's chalke, the mooring hook 5 rotates around an axis, releasing the chaly. After the detachment of the chuck under the action of the spring 7, the mooring hook 5 returns to the working position, and after lowering the water level to the base of the upper float 3 under the influence of the spring 8, the catch 6 returns to the working position. The release of the chalk in both cases leads to the unmooring of the vessel, which can no longer hang on the eyes, or, conversely, be nailed with it. As can be seen from the description, the device avoids an emergency situation for the ship and the structure on which it is located. Claim 1. In-depth float for mooring vessels, including a main float with an upper carriage, a support chassis and a mooring hook, characterized in that, in order to provide an automatic unmooring of the vessel when the eye is wedged in the mortgage parts and to improve performance, two additional floats, kinematically connected lever, and the main float slots are made, placed - one above the waterline, and the other below, in which additional floats are installed, and The main hook is provided with a latch interacting with the lever, and is pivotally connected to the upper carriage. 2. An open floating vessel for mooring a vessel according to claim 1, characterized in that springs are mounted on the hinges of the mooring hook and lock.
