Description
Anordning ved hydraulisk manøvrert skipslukedeksel. Device for hydraulically operated hatch cover.
Denne oppfinnelse vedrører en anordning ved hydraulisk manøvrert skipslukedeksel som består av sammenhengslete seksjoner av stive plater, hvorav en plate er hengslet til en lukesidekant og svinges om denne hengselakse av hydraulisk trykkmedium som virker i en svingemotor. This invention relates to a device for a hydraulically operated ship's hatch cover which consists of connected sections of rigid plates, one plate of which is hinged to a hatch side edge and is pivoted about this hinge axis by hydraulic pressure medium acting in a swing motor.
En kjent utførelse består i at det finnes et flertall slike seksjoner, for eksempel fire, hvorav to seksjoner er hengslet til hver sin motstående lukesidekant, mens de to andre seksjoner er hengslet til hver sin av de to sidekantseksjoner, og ved hjørnene ved den motsatte sidekant er styrt i spor. A known design consists in the fact that there are a plurality of such sections, for example four, of which two sections are hinged to each of the opposite hatch side edges, while the other two sections are hinged to each of the two side edge sections, and at the corners at the opposite side edge is controlled in tracks.
Det nye ved oppfinnelsen er at hengslene, som forbinder den ene seksjonsplate med lukekarmen, er således utformet at hengslenes respektive hengseltapper er forsynt med radialt rettete skovler opptatt i svingemotorens trykkammere og ved hjelp av armer er forbundet med lukeseksjonen mens svingemotorhuset er fastgjort til lukekarmen eller en med denne sammenhengende del. The new thing about the invention is that the hinges, which connect one sectional plate to the hatch frame, are designed in such a way that the hinges' respective hinge pins are provided with radially aligned vanes engaged in the swing motor's pressure chambers and are connected to the hatch section by means of arms while the swing motor housing is attached to the hatch frame or a with this connected part.
Ytterligere trekk ved oppfinnelsen vil Further features of the invention will
fremgå av det etterfølgende, hvori det er henvist til de medfølgende tegninger hvor det er vist et utførelseseksempel, og hvor: can be seen from what follows, in which reference is made to the accompanying drawings where an example of execution is shown, and where:
Fig. 1 viser et utsnitt av en skipsluke med tilhørende lukedeksel, vist i lukket stilling og sett ovenfra. Fig. 2 viser skipsluken med tilhørende lukedeksel, sett fra siden. Fig. 3 viser i litt større målestokk det samme som i fig. 2, men med lukedekslet åpent. Fig. 4 viser et snitt gjennom svinge- motoren. Fig. 1 shows a section of a ship's hatch with associated hatch cover, shown in the closed position and seen from above. Fig. 2 shows the ship hatch with associated hatch cover, seen from the side. Fig. 3 shows on a slightly larger scale the same as in fig. 2, but with the hatch cover open. Fig. 4 shows a section through the swing- the engine.
Idet det henvises til fig. 1, vises det her en lukekarm 10, som dekkes av plate-seksjoner 11 og 12, som tilsammen danner en lukedekselhalvdel, idet den ytre seksjonsplate 12 ved sin frie endekant 13 i lukket stilling ligger an mot en identisk eller speilbilledformig seksjonsplate 12a, som bare er delvis inntegnet. Referring to fig. 1, a hatch frame 10 is shown here, which is covered by plate sections 11 and 12, which together form a hatch cover half, with the outer section plate 12 resting at its free end edge 13 in the closed position against an identical or mirror-image section plate 12a, which only is partially subscribed.
Seksjonsplaten 11 er opplagret svingbart om en hengselakse 14 ved lukekarmen, og seksjonsplatene 11 og 12 er leddet sammen ved deres møtende endekanter ved 15. Seksjonsplaten 12 har ved sin frie endekant styringer 16, slik at når seksjonsplaten 11 svinges om hengselaksen 14, slik at når seksjonsplaten 11 svinges om hengselaksen 14, hviler styringene 16 på lukekarmen mens den motsatte endekant løftes sammen med nabokanten på seksjonsplaten 11. På i og for seg kjent måte dannes The sectional plate 11 is supported pivotably about a hinge axis 14 at the hatch frame, and the sectional plates 11 and 12 are hinged together at their meeting end edges at 15. The sectional plate 12 has guides 16 at its free end edge, so that when the sectional plate 11 is pivoted about the hinge axis 14, so that when the section plate 11 is swung around the hinge axis 14, the guides 16 rest on the hatch frame while the opposite end edge is lifted together with the neighboring edge of the section plate 11. In a manner known per se,
styringene 16 av et kasseformet bærestykke the guides 16 of a box-shaped support piece
17 for to ruller 18 og 19, som styres av 17 for two rolls 18 and 19, which are controlled by
lukekarmen. Selve bærestykket er opplagret svingbart om en vertikal svingetapp 20. Det finnes dessuten på bærestykket 17 hatch frame. The support piece itself is stored pivotably about a vertical pivot pin 20. There is also on the support piece 17
en låsestang 21 (se fig. 3) som er aksialfor-skyybart styrt med en tapp 22 opptatt i en sliss 23, slik at låsestangen 21 med seksjonsplaten 12 når denne er svinget opp til loddrett stilling, vil gli ned i en låsefor-dypning 24 og derved låse fast seksjonsplatene 11 og 12 i loddrett, åpen stilling. Ved å løfte opp tappen 22 bringes låsestangen 21 ut av låsestilling. Tappen 22 kan da bringes inni en vinkelgren 25 for å holde låsestangen ute av inngrep ved føring til seksjonsplatenes lukkende stillinger. a locking rod 21 (see fig. 3) which is axially displaceable controlled with a pin 22 engaged in a slot 23, so that the locking rod 21 with the section plate 12, when it is swung up to a vertical position, will slide down into a locking recess 24 and thereby lock the section plates 11 and 12 in a vertical, open position. By lifting up the pin 22, the locking rod 21 is brought out of the locking position. The pin 22 can then be brought inside an angle branch 25 to keep the locking rod out of engagement when guiding the section plates to the closing positions.
husene så å si ikke tar mere plass enn de vanlige grovdimensj onerte hengsler som likevel må anvendes. Man reduserer dessuten det ellers nødvendige pass og vedlike-hold, fordi disse svingemotorer er selvsmør-ende; som bekjent brukes olje som hydraulisk trykkmedium. the housings, so to speak, do not take up more space than the usual roughly dimensioned hinges that still have to be used. You also reduce the otherwise necessary inspection and maintenance, because these swing motors are self-lubricating; As you know, oil is used as a hydraulic pressure medium.
Den hittil vanlige utførelse ved slike lukedeksler har vært at hydrauliske stem-pelsylindre har virket mot lukedekslene for å bringe dem til og fra åpnet stilling. Ifølge oppfinnelsen foreslås følgende løsning. The hitherto common design for such hatch covers has been that hydraulic piston cylinders have acted against the hatch covers to bring them to and from the open position. According to the invention, the following solution is proposed.
På en sokkel 26 ved den tilhørende karmkant er det fastskrudd to langstrakte hus 27, 28 for to hydrauliske svingemotorer. Da disse er av lik utførelse, beskrives bare den ene av disse nærmere. Fra hver ende av huset 27 løper det ut en svingetapp 29, 30, hvortil det er festet hvert sitt hengsel-blad eller hengselarm 31, 32. Disse hengsel-armer er festet til braketter 33 som danner en integrerende del av seksjonsplaten 11. Two elongated housings 27, 28 for two hydraulic swing motors are screwed onto a base 26 at the associated frame edge. As these are of similar design, only one of these is described in more detail. From each end of the housing 27 runs out a pivot pin 29, 30, to which each hinge leaf or hinge arm 31, 32 is attached. These hinge arms are attached to brackets 33 which form an integral part of the section plate 11.
Rørledninger er tilkoblet huset ved 34 og 35 og tilfører hydraulisk trykkmedium til det indre av huset 27. Som antydet i fig. 4 er husets indre med skillevegger 36, 37 som ligger an mot den sentrale rotor 38, oppdelt i to deler, som igjen oppdeles i trykkammere ved hjelp av skovler 39, 40, som løper radialt ut fra rotoren 38. Her-ved dannes et første sett trykkammere 41A og 4 IB og et annet sett trykkammere 42A og 42B, som står i forbindelse med hver-andre over kanaler 43, 44. Det vil fremgå at settet 41 virker motsatt settet 42, slik at tilførselen av trykkmedium til settet 41 vil svinge svingemotorens rotor med urviser-retningen, og tilførsel av trykkmedium til settet 42 vil svinge rotoren mot urviserret-ningen. Fordi svingetappene 29, 30 er fast forbundet med rotoren 38, vil dette der-med bevirke svingning av seksjonsplaten ] 1 til og fra loddrett stilling fra og til dens vannrette, lukkende stilling. Pipe lines are connected to the housing at 34 and 35 and supply hydraulic pressure medium to the interior of the housing 27. As indicated in fig. 4 is the interior of the housing with partitions 36, 37 which abut against the central rotor 38, divided into two parts, which are again divided into pressure chambers by means of vanes 39, 40, which run radially out from the rotor 38. Here, a first set of pressure chambers 41A and 4 IB and another set of pressure chambers 42A and 42B, which are connected to each other via channels 43, 44. It will be seen that the set 41 acts opposite to the set 42, so that the supply of pressure medium to the set 41 will fluctuate the swing motor's rotor clockwise, and supply of pressure medium to the set 42 will swing the rotor anti-clockwise. Because the pivot pins 29, 30 are fixedly connected to the rotor 38, this will thereby cause oscillation of the section plate ] 1 to and from the vertical position from and to its horizontal, closing position.
Ved denne utførelse er det blant annet søkt oppnådd, at hele installasjonen er blitt forenklet, de tidligere anvendte stempel-sylindere faller bort, mens svingemotor- With this design, it has been sought to achieve, among other things, that the entire installation has been simplified, the previously used piston cylinders are eliminated, while the swing motor
