Anordning for hydraulisk vinsj anlegg til forhaling og fortøyning av skip. Device for hydraulic winch system for hauling and mooring ships.
Foreliggende oppfinnelse angår en anordning ved hydraulisk vinsj anlegg til forhaling og fortøyning av skip. Når det gjel-der vinsjer av denne art er det tidligere The present invention relates to a device for a hydraulic winch system for hauling and mooring ships. When it comes to winches of this kind, it is earlier

under disse forhold må det hydrauliske anlegg hele tiden være i drift, og dette byr under these conditions, the hydraulic system must be in operation at all times, and this offers
på den ulempe ved de kjente anlegg at en on the disadvantage of the known facilities that a
kraftig pumpeenhet som f. eks. har en elek-tro-motor på 65 Hk og som er nødvendig powerful pump unit such as has an elek-tro engine of 65 Hp and which is necessary
for forhaling av fartøyet fortsatt må være for the delay of the vessel must still be
i drift sålenge fartøyet ligger fortøyet selv in operation as long as the vessel is moored itself
om det da ikke krever med enn 5 Hk ytelse. if it then requires no more than 5 HP performance.
Resultatet av dette er at en kostbar motor-pumpeenhet for det hydrauliske anlegg er The result of this is that an expensive motor-pump unit for the hydraulic plant is
i drift for å yte kanskje 5 Hk og ikke kan in operation to provide maybe 5 Hp and cannot
benyttes til andre formål ombord, f. eks. used for other purposes on board, e.g.
ved drift av lastevinsjer. when operating cargo winches.
Hensikten med foreliggende oppfinnelse er å oppheve denne ulempe, noe som The purpose of the present invention is to eliminate this disadvantage, which
er oppnådd ved at det hydraulisk drevne is achieved by the hydraulically driven
vinsj eanlegg som omfatter en stor kraftig winch system which includes a large powerful
pumpeenhet, på en hensiktsmessig måte er pump unit, in an appropriate way is
tilkoplet et mindre, hydraulisk pumpe- connected to a smaller hydraulic pump
aggregat med vesentlig mindre kapasitet enn hovedpumpen, beregnet på å opprett-holde et passe strekk i fortøyningstrossene. På denne måte kan den store kraftige motor-pumpeenhet anvendes for andre formål slik at enheten kan utnyttes fullt ut og ikke beslaglegges bare til fortøyningen. unit with a significantly smaller capacity than the main pump, designed to maintain a suitable tension in the mooring lines. In this way, the large, powerful motor-pump unit can be used for other purposes so that the unit can be fully utilized and not seized only for the mooring.
Det er fra forskjellige felter kjent å kople inn ett eller flere aggregater etter behov til drift av en maskin, og disse aggregater kan godt være av forskjellig størrelse, men det er ikke dette som er bakgrunn for foreliggende oppfinnelse. Oppfinnelsen be-står, som neynt, i å nyttiggjøre seg en kraftig motor-pumpeenhet når det ikke lenger er behov for alt arbeid den kan utføre bare til å holde fartøyet fortøyet. It is known from various fields to connect one or more aggregates as needed to operate a machine, and these aggregates may well be of different sizes, but this is not the background of the present invention. The invention consists, as mentioned, in making use of a powerful motor-pump unit when there is no longer a need for all the work it can perform just to keep the vessel moored.
Oppfinnelsen angår således en anordning ved hydraulisk vinsj anlegg til forhaling og fortøyning av skip, omfattende en vinsj - motor som under forhalingsoperasjonen drives av et hovedaggregat hvis overflødige drivmedium ledes tilbake til sugesiden gjennom en innstillbar ventil koblet i parallell med vinsj motoren, og den er i det vesent-lige kjennetegnet ved at det parallellt med hovedaggregatet er anordnet et ytterligere hydraulisk pumpeaggregat med vesentlig mindre kapasitet enn hovedaggregatet, hvilket ytterligere pumpeaggregat leverer drivmedium til vinsj motoren under mooring, hvorved hovedaggregatet frigjøres for eventuell annen vinsj drift, f. eks. lasting og lossing, og at det i vinsj motorens trykkledning er anordnet et trykkfølsomt organ som påvirker drivmotoren for det ytterligere pumpeaggregat. The invention thus relates to a device for a hydraulic winch system for hauling and mooring ships, comprising a winch motor which during the hauling operation is driven by a main unit whose excess propellant is led back to the suction side through an adjustable valve connected in parallel with the winch motor, and it is in the essential characteristic in that an additional hydraulic pump unit with a significantly smaller capacity than the main unit is arranged parallel to the main unit, which additional pump unit supplies drive medium to the winch motor during mooring, whereby the main unit is freed for any other winch operation, e.g. loading and unloading, and that a pressure-sensitive organ is arranged in the winch motor's pressure line which affects the drive motor for the additional pump unit.

sen vil fremgå av den følgende beskrivelse under henvisning til tegningen som skjema- then will appear from the following description with reference to the drawing as schematic

Gjennom en tilbakeslagsventil 4 føres det hydrauliske medium gjennom en ledning 5 figure shows a hydraulically driven winch system for hauling and mooring ships, made in accordance with the invention. 1 denotes a hydraulic pump with oil reservoir 2 and electric motor 3 for operation of the pump 1. Through a non-return valve 4, the hydraulic medium is fed through a line 5
til selve vinsjen og gjennom en ledning 7 to the winch itself and through a wire 7
tilbake fra denne til reservoaret 2. En regu-leringsventil 8 er ved hjelp av ledninger 9 back from this to the reservoir 2. A control valve 8 is by means of lines 9
koplet parallellt med vinsjen for omledning av hydraulisk drivmedium som står under trykk. Dette trykk innstilles ved hjelp av reguleringsventilen 8, hvormed man bestemmer strekket i trossen 10. connected in parallel with the winch for the diversion of pressurized hydraulic drive medium. This pressure is set using the control valve 8, which determines the tension in the rope 10.
I henhold til oppfinnelsen er det i tilslutning til den vanlige motor-pumpe- According to the invention, in addition to the usual motor-pump

Når pumpeenheten 11, 12 raulic drive medium for the winch 6 when this is only to ensure sufficient tightening of the hawser after the vessel has been brought to the desired position. When the pump unit 11, 12

vil trykket falle og bryteren 13 vil kople om polene slik at motoren 12 vil gå med høyeste hastighet og levere tilstrekkelig oljemengde til at denne slakk tas hurtig inn. Hvis på den annen side en plutselig stramning skulle inntre ville vinsjen 6 bli trukket i motsatt retning og den vil «pumpe» olje gjennom reguleringsventilen. the pressure will drop and the switch 13 will switch the poles so that the motor 12 will run at the highest speed and deliver a sufficient quantity of oil so that this slack is taken up quickly. If, on the other hand, a sudden tightening were to occur, the winch 6 would be pulled in the opposite direction and it would "pump" oil through the control valve.

The additional hydraulic motor-pump unit which according to the invention is to be connected to a twelve-tonne winch only needs to deliver 210 l/min. when the engine runs at 1800 rpm. In polomkop-
lingen settes hastigheten ned til en tredje- ling, the speed is reduced to a third
del, nemlig til 600 omdr./min., og motoren gir da 5 Hk med en oljemengde på 70 l/min. part, namely to 600 rpm, and the engine then produces 5 Hp with an oil quantity of 70 l/min.

Om man anvendte, på samme måte If one applied, in the same way
som tidligere, den store motor-pumpeenhet 1, 2, 3, måtte reguleringsventilen 8 stilles inn slik at passasjen av 910 liter i minuttet førte til det trykk i ledningen 5 som i vinsjen 6 vil sørge for det ønskede strekk i trossen 10, og man kan lett forestille seg hvor uhensiktsmessig dette er rent bort- as before, the large motor-pump unit 1, 2, 3, the control valve 8 had to be set so that the passage of 910 liters per minute led to the pressure in the line 5 which in the winch 6 will ensure the desired tension in the rope 10, and one can easily imagine how inexpedient this is purely away-
sett fra at et stort kostbart aggregat blir opptatt med et arbeid som godt kan utføres av et aggregat som gir 70 l/min. og ofte også mindre enn dette. from the point of view that a large, expensive aggregate is occupied with work that can well be carried out by an aggregate that produces 70 l/min. and often even less than this.
Disse tall er også bare rene eksempler, These numbers are also just pure examples,
og det hydrauliske system kan naturligvis av fagfolk tilpasses de forhold vinsjen skal arbeide under, og hensikten er, som nevnt, and the hydraulic system can of course be adapted by professionals to the conditions under which the winch will work, and the purpose is, as mentioned,
