Description
458114 10 15 20 25 30 35 under kranen, fig. 2 visar ett ändrat utförande av stabiliseringsanordningen som är visad i fíg. 1. fig. 3 visar ett andra utförande av en stabiliseringsanordníng, fiq. 4 visar ett tredje utförande av en stabilíseringsanord- ning, och fíg. 5 visar ett fjärde utförande av en stabiliseríngsanord- ning. 458114 10 15 20 25 30 35 under the crane, Fig. 2 shows a modified embodiment of the stabilizing device shown in fig. Fig. 3 shows a second embodiment of a stabilizing device, fig. 4 shows a third embodiment of a stabilizing device, and fig. 5 shows a fourth embodiment of a stabilizing device.
Den i fig. l visade kranfarkosten omfattar ett skrov 2 delvis nedsänkt under vattenytan vilket. genom ihåliga pelare 3 av vilka endast en är visad. här en arbetsplattform 4, på vilken en kran 5 är anordnad.The crane vessel shown in Fig. 1 comprises a hull 2 partially submerged below the water surface, which. through hollow pillars 3 of which only one is shown. here a work platform 4, on which a crane 5 is arranged.
Föreliggande stabiliseringsanordning är företrädesvis inrymd i två pelare. även om det är möjligt att rymma stabiliserings- anordningen i en eller fyra pelare.The present stabilizing device is preferably housed in two pillars. although it is possible to accommodate the stabilizer in one or four pillars.
I fiq. l består stabiliseringsanordningen av en tät lufttank 6. som kan röras vertikalt inuti den ihåliga pelaren medelst en tryckcylínder 7. I den ritade positionen är lufttanken i pelaren åtminstone till större delen över vattenytan, som är i jämnhöjd med vattenytan l. Dessutom är förbindelser 8 till omkringliggande vatten anordnade vid botten av den ihåliga pelaren. Genom att flytta ned lufttanken 6 kommer kranfar- kosten att få en ökad bärighet vilket kompenserar kraften på kranfarkosten under lyftet i sådan grad att kranfarkosten för- blir horisontell inom mycket snäva gränser. Vid nedsättningen av lasten på en plattform återställs lufttanken till sitt upp- lyfta läge över vattenytan.I fiq. 1, the stabilizing device consists of a tight air tank 6. which can be moved vertically inside the hollow column by means of a pressure cylinder 7. In the drawn position the air tank in the column is at least for the most part above the water surface, which is level with the water surface 1. In addition, connections 8 to surrounding water arranged at the bottom of the hollow pillar. By moving the air tank 6 down, the crane craft will have an increased bearing capacity, which compensates for the force on the crane craft during the lift to such an extent that the crane craft remains horizontal within very narrow limits. When lowering the load on a platform, the air tank is restored to its raised position above the water surface.
Istället för tryckcylindern 7 är det möjligt, í enlighet med utförandet som visas i fig. 2. att åstadkomma rörelsen av” lufttanken 6 genom att använda en draganordning 9. reras från arbetsplattformen 4. som manöv- Stabíliseringsanordníngen som visas i fig. 3 omfattar ett bar- lastblock ll som är vertikalt rörligt i den ihåliga pelaren 3 10 15 20 25 30 35 458114 med hjälp av en lyftanordning 10, som manövreras från platt- formen 4, varvid specifika vikten av detta block är högre än vattnets. Under ett lyft med kranen sänks ballastblocket ll fort men gradvis till det streckade läget som visas i fig. 3. varemot då lasten sätts på en plattform barlastblocket åter- ställs till sitt upplyfta läge över vattenytan. Dessutom är den ihåliga pelaren förbunden med omgivande vatten genom öpp- ningar 12.Instead of the pressure cylinder 7, it is possible, in accordance with the embodiment shown in Fig. 2, to effect the movement of the air tank 6 by using a traction device 9. is moved from the working platform 4. as the operating Stabilization device shown in Fig. 3 comprises a ballast block 11 which is vertically movable in the hollow column 3 by means of a lifting device 10, which is operated from the platform 4, the specific gravity of this block being higher than that of the water. During a lift with the crane, the ballast block II is lowered quickly but gradually to the dashed position shown in Fig. 3. whereas when the load is placed on a platform, the ballast block is returned to its raised position above the water surface. In addition, the hollow column is connected to surrounding water through openings 12.
Stabilíseringsanordningen enligt fig. 4 består av en kolv 13, som kan röras av en tryckcylinder 14 i den håliga pelaren som är konstruerad som en cylinder. I toppen är cylindern förbun- den med omkringliggande luft genom ett luftrör 15, varemot öppningarna 16 förbinder utrymmet i cylindern under kolven 13 med omkringliggande vatten. Dessutom är kolven 13 försedd med en tätning 17, och sålunda förblir det luftfyllda cylinderrum~ met över kolven separerat från det vattenfyllda rummet under KOIVBD 13 .The stabilizing device according to Fig. 4 consists of a piston 13, which can be moved by a pressure cylinder 14 in the hollow column which is constructed as a cylinder. At the top, the cylinder is connected to the surrounding air through an air pipe 15, whereas the openings 16 connect the space in the cylinder under the piston 13 with the surrounding water. In addition, the piston 13 is provided with a seal 17, and thus the air-filled cylinder space above the piston remains separated from the water-filled space below the KOIVBD 13.
Stabiliseringsanordningen enligt fig. 5 omfattar en kolvkropp 19. som är konstruerad på ett utdraget sätt och kan röras i den ihåliga pelaren 3. som är konstruerad som en cylinder. medelst en lyftande cylinder 20. varvid öppningen i bottnen av den ihåliga pelaren släpper igenom kolven 19. översidan av den ihåliga pelaren är även förbunden genom en luftledning 21 med den omkringliggande luften. Tätningen mellan kolvkroppen 19 och innerväggen åstadkoms med hjälp av någon lämplig tätninga- del 18.The stabilizing device according to Fig. 5 comprises a piston body 19. which is constructed in an elongated manner and can be moved in the hollow column 3 which is constructed as a cylinder. by means of a lifting cylinder 20. the opening in the bottom of the hollow pillar letting through the piston 19. the upper side of the hollow pillar is also connected by an air duct 21 to the surrounding air. The seal between the piston body 19 and the inner wall is provided by means of any suitable sealing member 18.
Driften av tryckcylindrarna 7. 14. den lyftande cylindern 20. draganordningen 9, och den lyftande anordningen 10 är styrd av en dator på känt sätt.The operation of the pressure cylinders 7. 14. the lifting cylinder 20. the towing device 9, and the lifting device 10 are controlled by a computer in a known manner.
Under hela cykeln av lyftning, förflyttning, och nedsättning av lasten med hjälp av en kran behålls arbetsplattformen horisontell inom mycket snäva gränser medelst föreliggande dynamiskt arbetande stabiliseringsanordning. som även kan fortsätta att fungera under inte alltför stora vågrörelser. 458 10 15 114 Uppfínníngen kan även användas på ett lyftfartyg som inte har någon kran utan överför en last till en plattform genom att snabbt öka det lyftande skeppets trimning eller ta in en last genom att snabbt minska trimningen. För att åstadkomma denna snabba förändring av trímningen kan uppfinningen användas på samma sätt som ovan beskrivits.Throughout the cycle of lifting, moving and lowering the load by means of a crane, the work platform is kept horizontal within very narrow limits by means of the present dynamically operating stabilizing device. which can also continue to function during not too large wave motions. 458 10 15 114 The invention can also be used on a lifting vessel which has no crane but transfers a load to a platform by rapidly increasing the tuning of the lifting ship or taking in a load by rapidly decreasing the tuning. To achieve this rapid change in trimming, the invention can be used in the same manner as described above.
Hítintílls har en vertikal riktning angivits. för att visa enkelheten av konstruktionen. Andra rörelseriktningar, t.9X. en horisontell, kan lika väl tänkas eftersom tömning av vatten kan ske i varje riktning och inte endast nedåt.Hítintílls has a vertical direction indicated. to show the simplicity of the design. Other directions of movement, t.9X. a horizontal, can just as well be imagined because emptying of water can take place in any direction and not only downwards.
Slutligen påpekas att uppfinningen naturligtvis inte är begränsad till de ovan angivna utförandena, utan andra vari- anter som arbetar i enlighet med de ovan angivna principerna faller också inom föreliggande uppfinnings ram.Finally, it is pointed out that the invention is of course not limited to the above-mentioned embodiments, but other variants which operate in accordance with the above-mentioned principles also fall within the scope of the present invention.
