Description

464 298 lyftkranens krok som farkostens lyftkabel. 464 298 The crane's hook as the vehicle's lifting cable.

Ett annat syfte med uppfinningen är att framställa en robust an- ordning med få detaljer och som klarar en svår operatíonsmiljö.Another object of the invention is to produce a robust device with few details and which can handle a difficult operating environment.

Dessa syften uppnås med en anordning av inledningsvis nämnt slag där lyftoket som medelst linor är fäst vid en lyftöglas nedre del har två åtskiljsbara delar anordnade så att de, då delarna är åtskilda, medger att lyftoket i sidled föres in mot och sluts omkring lyftkabeln. I öppningar i lyftokets väggar omkring tangen- tiellt anbringade axlar är svängbara spärrorgan anordnade. Utan- för lyftblocket sträcker sig längre hävstångsdelar av spärrorganen vilka medelst andra linor är fästa i ett längs en lyftöglas lång- sträckta, med en stoppklack försedda nedre del anbringat element, sagda element förskjutbart mellan ett övre fixerbart läge och ett av stoppklacken fixerat undre läge.These objects are achieved with a device of the kind mentioned in the introduction where the lifting yoke which by means of ropes is attached to the lower part of a lifting eye has two separable parts arranged so that, when the parts are separated, they allow the lifting yoke to be moved laterally towards and closed around the lifting cable. Swivel locking means are provided in openings in the walls of the lifting yoke around tangentially mounted shafts. Extending beyond the lifting block extend longer lever parts of the locking means which by means of other ropes are fastened in an elongate element arranged along a lifting eye, with a stop lug provided with a stop lug, said element slidably between an upper fixable position and a lower position fixed by the stop lug.

Uppfinningen kommer nu att beskrivas närmare i en tillämpning med en via en kabel fjärrmanövrerad undervattensfarkost. Uppfinningen beskrivs med hänvisning till bifogade ritningar.The invention will now be described in more detail in an application with a submarine remotely operated via a cable. The invention is described with reference to the accompanying drawings.

Fig 1 visar en totalbild i perspektiv av anordningen tillsammans med farkostens kabel.Fig. 1 shows an overall view in perspective of the device together with the cable of the vehicle.

Fig 2 visar ett snitt genom anordningens lyftok.Fig. 2 shows a section through the lifting yoke of the device.

Fig 3 - 5 visar i principskisser tre faser under sjösättning.Figures 3 - 5 show in principle sketches three phases during launching.

Fig 6 - 8 visar i principskisser tre faser under bärgning.Figures 6 - 8 show in principle sketches three phases during salvage.

Fig 1 visar lyftoket 1 med sina delar 2 och 3 åtskilda så att de kan anbringas omkring en i farkosten 30 anbringad lyftkabel 4.Fig. 1 shows the lifting yoke 1 with its parts 2 and 3 separated so that they can be arranged around a lifting cable 4 arranged in the vehicle 30.

Genom en låsanordning 5 i delarnas fria ändar 6 och 7 kan dessa säkert sammanfogas omkring lyftkabeln. Det sammanfogade oket har en central genomgående öppning i vilken lyftkabeln kan löpa och i vilken öppning ett på farkosten anbringat lyftorgan 60 kan in- 464 298 föras. På lyftokets ovansida är tre första linor 8, B' och 8" fästa. Linornas andra ändar är fästa vid den_nedre med en stopp- klack 9 försedda delen av en med ett långsträckt undre parti 10 försedda lyftöglan 11. I öppningar 12, 12' och 12" i lyftokets väggar, varav två framgår av fig 2, är tre stycken spärrorgan 13, 13' och 13" vridbart anordnade omkring i lyftokets väggar tangentiellt monterade axlar 14, 14' och 14". En av axlarna visas i fig 2. Spärrorganen har i sin mot lyftokets centrumaxel vända kortare hävarmsdel 15, 15' och 15" en översida som bildar ett ^ horisontellt plan 16, 16' och 16" då spärrorganet är i spärrläge.Through a locking device 5 in the free ends 6 and 7 of the parts, these can be securely joined together around the lifting cable. The joined yoke has a central through-opening into which the lifting cable can run and into which opening a lifting member 60 mounted on the vessel can be inserted. The first three ropes 8, B 'and 8 "are attached to the upper side of the lifting yoke. The other ends of the ropes are attached to the lower part 9 provided with a stop lug 9 by a lifting loop 11 provided with an elongate lower portion 10. In openings 12, 12' and 12 "in the walls of the lifting yoke, two of which are shown in Fig. 2, three locking means 13, 13 'and 13" are rotatably arranged about axially mounted shafts 14, 14' and 14 "mounted tangentially in the walls of the lifting yoke. One of the shafts is shown in Fig. 2. The locking means have in their shorter lever part 15, 15 'and 15 "facing the center axis of the lifting yoke a upper side which forms a horizontal plane 16, 16' and 16" when the locking member is in the locking position.

I spärrorganens, på utsidan av lyftoket belägna längre hävarm 17, 17' och 17" är tre andra linor 18, 18' och 18" fästa. I yttre änden på varje spärrorgan är vikter 19, 19' och 19" anbringade.Longer levers 17, 17 'and 17 "located on the outside of the lifting yoke, three other ropes 18, 18' and 18" are attached. Weights 19, 19 'and 19 "are attached to the outer end of each locking member.

Andra änden av dessa linor är fästa i ett omkring lyftöglans 11 långsträckta undre parti 10 förskjutbart anbringat element 20.The other end of these ropes is attached to an elongate lower portion 10 slidably mounted around the lifting eye 11 of the lifting eye 11.

Detta kan medelst en låsbar sprint 21 fixeras i ett övre läge 22 och genom den i änden av lyftöglans 11 undre parti 10 anbringade stoppklacken 9 fixeras i ett nedre läge 23.This can be fixed by means of a lockable pin 21 in an upper position 22 and by means of the stop lug 9 arranged at the end of the lower part 10 of the lifting eye 11 fixed in a lower position 23.

I figur 3 visas hur anordningen, vid sjösättning av en farkost, efter anbringande omkring farkostens lyftkabel, av lyftkranen förs ned mot det på farkosten anordnade lyftorganet 60. Elemen- tet 20 är fixerat i sitt nedre läge 23. Lyftoket kan nu föras ned över farkostens lyftorgan 60 eftersom spärrorganen befinner sig i undanfört läge. Spärrorganen bringas nu som visas i fig 4 manuellt till sina spärrlägen, varefter lyft sker. Farkosten lyfts nu i de tre linorna 8, 8' och 8" medan de tre andra linorna 18, 18' och 18" är slaka. Farkosten sänks ned i vattnet och då den är i flytande tillstånd kommer lyftoket 1 att lyftas av farkostens lyftorgan 60. Fig 5 visar hur spärrorganen på grund av sin med tyngder försedda yttre del intar frigöringsläge och förblir där så att lyftoket kan avlyftas från farkostens lyftorgan. Anord- ningen kan av lyftkranen lyftas upp längs lyftkabeln, lyftoket öppnas och anordningen bekvämt avlägsnas från såväl lyftkabel som lyftkranens krok. 464 298 I figur 6 visas hur anordningen vid bärgning av farkosten, efter att ha anbringats omkring lyftkabeln och hakats på lyftkranens krok, har förts ned längs lyftkabeln till ett första läge, beredd att sänkas ned över farkostens lyftorgan 60. Elementet20 är nu fixerat i sitt övre läge 22.Figure 3 shows how the device, when launching a vehicle, after being fitted around the vehicle's lifting cable, is lowered by the lifting crane towards the lifting member 60 arranged on the vehicle. The element 20 is fixed in its lower position 23. The lifting yoke can now be lowered over the vehicle. lifting means 60 since the locking means are in the retracted position. The locking means are now manually brought to their locking positions as shown in Fig. 4, after which lifting takes place. The craft is now lifted in the three lines 8, 8 'and 8 "while the other three lines 18, 18' and 18" are slack. The vessel is lowered into the water and when it is in a floating state, the lifting yoke 1 will be lifted by the lifting means 60 of the vessel. Fig. 5 shows how the locking means, due to its weighted outer part, assume release position and remain there so that the lifting yoke can be lifted from The device can be lifted up by the crane along the lifting cable, the lifting yoke is opened and the device is conveniently removed from both the lifting cable and the hook of the crane. 464 298 Figure 6 shows how the device when salvaging the vessel, after being fitted around the lifting cable and hooked on the hook of the crane, has been lowered along the lifting cable to a first position, ready to be lowered over the lifting means 60 of the vessel. The element 20 is now fixed in its upper position 22.

I fig 7 visas hur farkostens lyftorgan 60 förs in i lyftoket och lyfter detta så att de första linorna 8, 8' och 8" slaknar, var- vid spärranordningarna av den längre hävarmens tyngd bringas att inta frigöringsläget. Fig 8 visar hur linorna 8, 8' och 8" sträcks då lyftöglan 11 lyfts och spärrorganen förs till sitt spärrläge varvid farkostens lyftorgan 60 kommer att vila på spärrorganen och farkosten lyfts. Då farkosten sänks ned på fast underlag, ett fartygsdäck t ex, kommer lyftorganet 60åter att lyfta lyft- oket 1 så att de första linorna 8, 8' och 8" slaknar och spärr- organen 13, 13' och 13" av sin tyngd fälls ned och frigör lyft- organet 60 varvid anordningen kan lyftas av, lyftoket öopnas och avlägsnas från lyftkabeln.Fig. 7 shows how the lifting means 60 of the vessel is inserted into the lifting yoke and lifts it so that the first lines 8, 8 'and 8 "slacken, whereby the locking devices of the weight of the longer lever are caused to assume the release position. Fig. 8 shows how the lines 8, 8 'and 8 "are stretched when the lifting loop 11 is lifted and the locking means are moved to their locking position, whereby the vehicle's lifting means 60 will rest on the locking means and the vessel is lifted. When the craft is lowered onto a solid surface, a ship's deck for example, the lifting means 60 will again lift the lifting yoke 1 so that the first ropes 8, 8 'and 8 "slacken and the locking means 13, 13' and 13" fold down from their weight. down and releases the lifting means 60 whereby the device can be lifted off, the lifting yoke is opened and removed from the lifting cable.

Uppfinningen har här åskådliggjorts i en tillämpning vid en kabel- försedd undervattensfarkost men kan givetvis användas för vilken kabelförsedd last som helst som skall förflyttas. Likaså kan an- ordningen användas på laster utan lyftkabel varvid den manuellt får anbringas på lastens lyftorgan.The invention has been illustrated here in an application in a cable-equipped underwater vehicle, but can of course be used for any cable-loaded cargo to be moved. The device can also be used on loads without a lifting cable, whereby it may be manually mounted on the lifting means of the load.
