Menetelmä ja laitteisto potkurilaitteen irrottamiseksi uivan aluksen pohjassa olevasta aukosta ja asentamiseksi siihenA method and apparatus for removing and installing a propeller device from an opening at the bottom of a floating vessel
Esillä olevan keksinnön kohteena on patenttivaatimuksen 1 5 johdanto-osan mukainen menetelmä potkurilaitteen irrottamiseksi uivan aluksen pohjassa olevasta aukosta ja asentamiseksi siihen sekä patenttivaatimuksen 4 johdanto-osan mukainen laitteisto.The present invention relates to a method according to the preamble of claim 1 for removing a propeller device from a hole in the bottom of a floating vessel, and to an apparatus according to the preamble of claim 4.
10 Esillä olevan keksinnön päämääränä on aikaansaada parannettu ja suhteellisen yksinkertainen ja luotettava menetelmä ja laitteisto potkurilaitteen irrottamiseksi ja asentamiseksi huoltoa, korjausta tai vaihtoa varten ilman tarvetta ajaa alusta telakalle. Tämä on erityisen tärkeää erilaisten off-15 shore teollisuuden käyttämien lauttojen yhteydessä, jotka lautat usein on suunniteltu pysymään paikallaan pitkiä aikoja, esim. jopa 20 vuotta. Tekniikan tasossa potkurilait-teet on asennettu ja irrotettu aluksen ulkopuolelta erilaisten nostolaitejärjestelyjen avulla. Nämä edellyttävät nor-20 maalisti sukeltajan käyttämistä nostoköysien kiinnittämiseksi potkurilaitteeseen. Tällaisen ulkopuolelta tapahtuvan potkurilaitteen irrotuksen ja asennuksen haittapuolena on se, että ne ovat voimakkaasti riippuvaisia sääolosuhteista. Huonossa säässä ei sukeltajaa voida käyttää turvallisuus-25 syistä tällaisiin töihin.It is an object of the present invention to provide an improved and relatively simple and reliable method and apparatus for removing and installing a propeller device for maintenance, repair or replacement without the need to drive the vessel to the shipyard. This is especially important with the various ferries used by the off-15 shore industry, which are often designed to stay in place for long periods of time, for example up to 20 years. In the prior art, propeller devices are installed and removed from the outside of the ship by various lifting arrangements. These require the use of a nor-20 paint diver to attach lifting ropes to the propeller assembly. The drawback of such an external propeller assembly is that it is heavily dependent on weather conditions. In bad weather, a diver cannot be used for such work for safety reasons.

Kuvioissa 1-3 on esitetty laitteisto potkurilaitteen 1 irrottamista ja asentamista varten aluksen pohjassa 8 olevaan aukkoon 9. Kuviossa esitetty potkurilaite 1 käsittää vedenalaisen, varsinaisen potkurin sisältävän osan 2 sekä 5 aluksen sisäpuolisen yläosan 3, joiden välissä on aukon 9 tiiviisti sulkeva laippaosa 4. Potkuri on yhdistetty tarkoituksenmukaisten vaihteistoelimien välityksellä väliakseliin 5, joka on puolestaan liitetty voimaelimiin 6, esim. sähkö-moottori tai dieselmoottori. Esitetyssä suoritusmuodossa 10 väliakseli 5 on irrotettava. Aukon 9 yhteyteen on järjestetty aluksen sisälle ylöspäin, vesirajan yläpuolelle ulottuva nostotila 7, jonka alaosaan on järjestetty läpikulku 13 väliakselia 5 varten. Nostotila 7 on muodostettu vesitiiviiksi. Nostotilan 7 sisäpuolelle on lisäksi järjestetty ei-15 esitetyt ohjauselimet potkurilaitteen 1 pitämiseksi oikeassa asennossa nostamisen ja paikoilleen laskemisen aikana.Figures 1-3 show apparatus for dismantling and mounting propeller device 1 in opening 9 in bottom 8 of the vessel. Propeller device 1 in the figure comprises an underwater actual propeller-containing part 2 and 5 an inner top part 3 of the vessel between is connected via appropriate transmission means to an intermediate shaft 5 which in turn is connected to the power means 6, e.g. an electric motor or a diesel engine. In the illustrated embodiment 10, the intermediate shaft 5 is removable. A lifting space 7 extending upwardly above the waterline is provided in connection with the opening 9, at the lower part of which is provided a passage 13 for the intermediate shaft 5. The lifting space 7 is formed watertight. In addition, non-illustrated control means are provided on the inside of the lifting space 7 for holding the propeller device 1 in the correct position during lifting and lowering.
Seuraavassa kuvataan vaiheet potkurilaitteen 1 erottamiseksi ja nostamiseksi pois aukosta 9. Tämä kuvaus on vain esimerk-20 ki eräästä edullisesta toteuttamistavasta, eikä sen tarkoituksena ole rajoittaa patenttivaatimuksessa määritettyä keksinnön suoja-alaa.The following describes the steps for separating and lifting the propeller device 1 from the opening 9. This description is merely an example of a preferred embodiment and is not intended to limit the scope of the invention as defined in the claim.

Seuraavana avataan potkuri- I * < ’·* * 30 laitteen aluksen runkoon liittävät kiinnityselimet ja asen netaan nostoköydet 12 potkurilaitteeseen 1 ja päästetään vesi nostotilaan 7. Lopuksi potkurilaite 1 nostetaan nosto- · 9 : tilan 7 kautta yläkautta pois tarvittavia toimenpiteitä ., : varten. Potkurilaitteen 1 asennus aukkoon 9 tapahtuu päin- • ·. 35 vastaisessa järjestyksessä. Nostotilaan 7 asennuksen yh- l · i teydessä jäävän veden poistamiseen voidaan käyttää ta- ; , vanomaisia pumppuelimiä.; Initially, remove the intermediate shaft 5 between the upper part 3 • 25 of the propeller unit 1 and the power unit 6, and at the same time disconnect the relevant electric wires and hydraulic hoses and any other pipes ···. ket. Next, the passage 13 is sealed watertight by a flange 11 (Fig. 2) and placed over the upper part 3 of the propeller device 1 • · · ;;; Next, open the props connecting the propeller I * <'· * * 30 to the hull of the vessel and install the hoisting ropes 12 to the propeller unit 1 and release the water into the lifting space 7. Finally, the propeller unit 1 is lifted through the lifting for.,:. The propeller assembly 1 is mounted in the opening 9 •. 35 in reverse order. In order to remove the water remaining in the installation of the lifting space 7, it can be used; , old-fashioned pump members.

Laitteistoon voidaan tehdä lukuisia muutoksia poikkeamatta patenttivaatimuksissa esitetystä keksinnön suoja-alasta. Esim. potkurilaitteen 1 yläosa 3 voitaisiin tehdä alunperin täysin paineveden kestäväksi, jolloin erillisen suojakuvun 5 10 käyttö ei ole tarpeen.Numerous changes can be made to the apparatus without departing from the scope of the invention as claimed. For example, the upper part 3 of the propeller device 1 could initially be made completely water-resistant, so that it is not necessary to use a separate protective cover 5 10.
