(54) Mekanisme til lukning henholdsvis åbning af en påfyldningsåbning i den øvre del af en tank.(54) Mechanism for closing or opening a filling orifice in the upper part of a tank, respectively.

Opfindelsen angår en mekanisme til lukning henholdsvis åbning af en påfyldningsåbning i den øvre del af en tank og af den art, der omfatter to indbyrdes parallelle, vandrette sidestyr beliggende på hver sin side af en påfyldningsåbningen afgrænsende krave, en i nævnte sidestyr ved hjælp af en trykluftcylinder bevægelig overdel, en plan lukkeplade, der kan bringes i anlæg mod kraven, en oven over overdelen anbragt kontraplade, samt organer til aktivering af lukkepladen.BACKGROUND OF THE INVENTION 1. Field of the Invention The invention relates to a mechanism for closing or opening a filling orifice in the upper part of a tank and of the kind comprising two mutually parallel horizontal lateral guides located on one side of a filling orifice collar, one in said lateral guide by means of a a compressed air cylinder movable top, a flat closure plate which can be brought into contact with the collar, a counter plate located above the top, and means for activating the closure plate.

CQ I almindelighed har tankene på deres overside et mandehul med en diameter på omkring 500 til 800 mm.CQ In general, the tanks on their upper side have a manhole with a diameter of about 500 to 800 mm.

t> OQ Dette mandehul lukkes af en lukkeanordning, der består af en flange, som ^ reducerer åbningen til en diameter på omkring 350 til 500 mm, og et låg eller dæksel, der sørger for tildækningen af den resterende åbning. Dækslet består ^ oftest af et cirkulært metalstykke, der lægger sig an mod flangen via en pakning.OQ This manhole is closed by a closure device consisting of a flange which ^ reduces the opening to a diameter of about 350 to 500 mm, and a lid or cover which provides for the covering of the remaining opening. The cover most often consists of a circular piece of metal which attaches to the flange via a gasket.

Spænde- eller lukkeorganer holder dækslet på plads under transport og sikrer det fornødne tryk mod pakningen. Det er nødvendigt at åbne dækslet før optankningen og at lukke det bagefter igen.Clamping or closing means hold the cover in place during transport and ensure the necessary pressure against the gasket. It is necessary to open the cover before refueling and to close it afterwards.

Det er nødvendigt ved betjeningen at have adgang til den øverste del af tanken. Her er der risiko for nedstyrtningsulykker, især når tankens top er dækket af spildte påfyldningsprodukter, der gør området ved dækslet glat.It is necessary for the operator to have access to the upper part of the tank. There is a risk of crash accidents here, especially when the top of the tank is covered with spilled filling products that make the area of the cover smooth.

Denne risiko er desto større, jo mere viskost påfyldningsproduktet er, f.eks. brændselsolie.This risk is the greater the more viscous the filling product, e.g. fuel oil.

Foruden denne fare kræver dækslerne en sådan betjeningstid, at den hæmmer ydeevnen af automatiske påfyldningsanlæg. Betjeningstiden vurderes til 80 sekunder under gunstigste omstændigheder, dvs. når der er installeret gangbro.In addition to this danger, the covers require such an operating time that it impairs the performance of automatic filling systems. The operating time is estimated at 80 seconds in favorable circumstances, ie. when a walkway is installed.

For at afhjælpe disse ulemper bar man udviklet trykfjernstyrede lukkemekanismer af den indledningsvis nævnte art.To remedy these disadvantages, pressure-controlled closure mechanisms of the kind mentioned above were developed.

En sådan lukkemekanisme, der f.eks. kendes fra fransk patentskrift 1.526. 122, har imidlertid den alvorlige ulempe, at der anvendes fjedre til åbning af dækslet og et fluidtrykpåvirket legeme, f.eks. en rundtgående luftring, til lukning af dækslet, hvorfor enhver driftsforstyrrelse eller afbrydelse i det trykf rem-bringende anlæg, specielt i tilfælde af ulykke eller uheld, omgående indebærer, at dækslet åbnes af fjedrene. Den kendte mekanisme giver altså ikke fuld sikkerhed for at dækslet i så fald forbliver lukket.Such a closing mechanism which e.g. is known from French patent 1,526. 122, however, has the serious disadvantage of using springs to open the cover and a fluid-pressurized body, e.g. a circular air ring, for closing the cover, so that any operational interruption or interruption in the pressure-generating system, especially in the event of an accident or accident, immediately entails opening the cover by the springs. Thus, the known mechanism does not give full assurance that the cover remains closed.

Opfindelsen tager sigte på at afhjælpe denne ulempe og med henblik herpå er en mekanisme ifølge opfindelsen ejendommelig ved, at lukkepladen og kontrapladen er fast forbundet med hinanden, og at nævnte organer' til aktivering af lukkepladen omfatter dels trykfjedre, beliggende mellem overdelen og lukkepladen, til at presse lukkepladen mod kraven, dels en oppustelig blære anbragt mellem overdelen og kontrapladen og indrettet til ved tilførsel af en komprimeret luftart fra det trykluftcylinderen drivende trykluftsystem at løfte lukkepladen imod trykfjederens virkning. I forhold til den kendte mekanisme bruger opfindelsen så at sige-den "omvendte" løsning, hvor lukkepladen af trykfjedrene vedvarende holdes lukket og først åbnes, når der føres trykfluidum til den oppustelige blære. En driftsforstyrrelse eller afbrydelse i det trykfrembringende an-læg får i tilfælde af ulykke eller uheld ingen alvorlig følge, heller ikke hvis blæren af en eller anden årsag, f.eks. slitage, skulle perforeres.SUMMARY OF THE INVENTION The invention seeks to alleviate this disadvantage and for this purpose, a mechanism according to the invention is characterized in that the closing plate and the counter plate are fixedly connected to each other and that said means for activating the closing plate comprise partly compression springs located between the upper and the closing plate. pressing the closure plate against the collar, and partly an inflatable bladder disposed between the upper and the counterplate and arranged to lift the closure plate against the action of the compression spring by supplying a compressed gaseous type from the compressed air cylinder. In relation to the known mechanism, the invention uses, so to speak, the "inverse" solution, in which the closing plate of the compression springs is kept permanently closed and only opened when pressure fluid is fed to the inflatable bladder. In the event of an accident or accident, a malfunction or interruption in the pressure-generating system will have no serious consequences, even if the bladder for some reason, e.g. wear, should be perforated.

Man opnår en meget enkel konstruktion, når kontrapladen i henhold til opfindelsen er forbundet med lukkepladen ved hjælp af bolte, som er ført gennem åbninger i overdelen.A very simple construction is obtained when the counter-plate according to the invention is connected to the closing plate by bolts which are passed through openings in the upper part.

Lukkepladens kombinerede bevægelse med lodret og vandret translation kan hensigtsmæssigt opnås, når trykcylinderen i henhold til en udførelsesform for opfindelsen i den ene ende har en åbning forbundet med en kilde for en komprimeret luftart gennem en T-ventil og i den ånden ende har eii åbning med en kilde for en komprimeret luftart gennem en T-ventil, hvorhos trykcylinderens stempelstang 3 145874 er hul og forbundet dels med en oppustelige blære, dels med førstnævnte T-ventil gennem åbninger i stemplet. Fordelen ved denne udformning er at de to translationsbevægelser automatisk følger efter hinanden alene ved betjening af T-ventilen og uden mulighed for forskydning af lukkepladen før aktivering af blæren.The combined movement of the closure plate with vertical and horizontal translation can conveniently be achieved when the pressure cylinder according to one embodiment of the invention has at one end an opening connected to a source of a compressed gas through a T-valve and at that end has no opening with a source of a compressed gas through a T-valve, the piston rod of the pressure cylinder 3 145874 being hollow and connected partly to an inflatable bladder and partly to the former T-valve through openings in the piston. The advantage of this design is that the two translation movements automatically follow one another only by operating the T-valve and without the possibility of displacement of the closing plate before activation of the bladder.

I henhold til endnu en udførelsesform for opfindelsen kan trykcylinderens stempel være formet som et hult legeme, der indeholder en med fjeder i retning bort fra stempelstangen belastet ventilklap, idet der i ventilklappen og i legemet findes passager til at sætte den ene henholdsvis den anden del af trykcylinderen i forbindelse med den hule stempelstang. Denne udformning giver fuld sikkerhed for gennemførelse af den komplette lukke- og åbnesekvens.According to yet another embodiment of the invention, the piston of the pressure cylinder may be shaped as a hollow body containing a spring-loaded valve flap away from the piston rod, with passageways in the valve flap and body for inserting one or the other part of the the pressure cylinder in connection with the hollow piston rod. This design provides complete assurance of completion of the complete closing and opening sequence.

I det følgende beskrives et udførelseseksempel på opfindelsen nærmere under henvisning til tegningen, på hvilken fig. 1 viser i perspektiv og skematisk en tankvogn med en mekanisme i-følge opfindelsen, fig. 2 og 3 et tværsnit af en del af mekanismen ifølge opfindelsen med lukkeplade i henholdsvis lukket og åben stilling, fig. 4 skematisk et pneumatisk styrekredsløb til mekanismen, og fig. 5 en detalje fra fig. 4.In the following, an exemplary embodiment of the invention is described in more detail with reference to the drawing, in which 1 is a perspective and schematic view of a tanker truck with a mechanism according to the invention; FIG. 2 and 3 are a cross-sectional view of a part of the mechanism according to the invention with the closing plate in the closed and open positions respectively; 4 schematically shows a pneumatic control circuit for the mechanism; and FIG. 5 shows a detail of FIG. 4th

I fig. 1 til 3 betegner 10 en tank, på hvis top der findes en cirkulær åbning 11 til påfyldning. Åbningen afgrænses af en krave 12, der kan lukkes med et låg eller et dæksel. Dækslet består af en cirkulær lukkeplade 13 med en pakning 14, som samvirker med kraven 12 til tilvejebringelse af tæt lukning af åbningen 11.In FIG. 1 to 3, 10 denotes a tank on whose top there is a circular opening 11 for filling. The opening is delimited by a collar 12 which can be closed with a lid or cover. The cover consists of a circular closure plate 13 with a gasket 14 which cooperates with the collar 12 to provide a tight closure of the opening 11.

Pladen kan udføre to translationsbevægelser, en lodret og en vandret, så at den kan fjernes fra åbningen.The plate can perform two translation movements, one vertical and one horizontal, so that it can be removed from the opening.

Pladens vandrette bevægelse sker ved hjælp af et første overstykke 18, på hvis kanter 25 og 26 der findes indadgående ruller 28 og 29, der bevæger sig i U-profiler 30 og 31, der ligger parallelt med hinanden og med tankens akse.The horizontal movement of the plate takes place by means of a first top piece 18, on whose edges 25 and 26 there are inwardly extending rollers 28 and 29, which move in U-profiles 30 and 31 which are parallel to one another and to the axis of the tank.

Dækslet vandrette bevægelse sker ved hjælp af f.eks. en pneumatisk donkraft 80, hvis stempelstang 82 er vist i fig. 1.The horizontal movement cover is made using e.g. a pneumatic jack 80 whose piston rod 82 is shown in FIG. First

Dækslets lodrette bevægelse sker ved hjælp af en oppustelig blære 65, der ligger an mod det første overstykke 18 og et andet overstykke 66, som er forbundet med lukkepladen 13 af frit gennem det første overstykke gående bolte 62 og 63, idet dækslets tillukning og lukkepladen 13's anlæg mod kraven 12 sikres af fjedre 60 og 61, der styres af boltene 62 og 63, hvilke fjedre med den ene ende ligger an mod lukkepladen 13 og med den anden ende mod det første overstykke 18.The vertical movement of the cover is effected by an inflatable bladder 65 abutting the first cover 18 and a second cover 66, which is connected to the closure plate 13 by bolts 62 and 63 passing freely through the first cover, the closure of the cover and the closure plate 13. abutments against the collar 12 are secured by springs 60 and 61, which are guided by the bolts 62 and 63, which springs with one end abut the closure plate 13 and with the other end against the first upper part 18.

Boltene 62 og 63 sidder fast i det andet overstykke 66 og går gennem pladen 18 i huller med en diameter, der er tilstrækkelig stor til at lade pla- 4 145874 den 18 bevæge sig lodret uden gnidning.The bolts 62 and 63 are secured to the second top piece 66 and pass through the plate 18 into holes of a diameter sufficiently large to allow the plate to move vertically without rubbing.

Blæren kan oppustes gennem en åbning 67 på en måde, der vil blive beskrevet nærmere i det følgende. Når blæren oppustes, udøver den en kraft på overstykkerne 18 og 66. Overstykket 18 forbliver ubevægeligt, fordi det holdes af rullerne; overstykket 66 hæver sig og medfører pladen 13 ved hjælp af boltene 62 og 63, idet fjedrene 60 og 61 sammentrykkes mellem pladen 13 og overstykket 18.The bladder can be inflated through an opening 67 in a manner that will be described in more detail below. When the bladder is inflated, it exerts a force on the headpieces 18 and 66. The headpiece 18 remains motionless because it is held by the rollers; the top piece 66 raises and enters the plate 13 by means of the bolts 62 and 63, the springs 60 and 61 being compressed between the plate 13 and the top piece 18.

I det følgende beskrives under henvisning til fig. 4 og 5 en pneumatisk styring til åbning og lukning af dækslet.The following is described with reference to FIG. 4 and 5 a pneumatic control for opening and closing the cover.

Denne består af en cylinder 80 med et stempel 81 og en stempelstang 82, der er i fast forbindelse med det andet overstykke 66; denne stang er desuden hul og forbundet med åbningen 67 til oppustning af blæren.This consists of a cylinder 80 with a piston 81 and a piston rod 82 which is in fixed connection with the second top piece 66; this rod is further hollow and connected to the bladder inflation 67.

Cylinderen 80 har to endestykker 80a og 80b; i nærheden af disse endestykker findes der to åbninger 83 og 84, som gennem T-ventiler 86 og 87 kan sættes i forbindelse med trykluftskilder 56 og 57 ved hjælp af tilslutninger 88, 89 og 88a, 89a. Ventilerne og koblingerne er ligeledes vist i fig.Cylinder 80 has two end pieces 80a and 80b; near these ends there are two openings 83 and 84 which can be connected through compressed air sources 56 and 57 by T-valves 86 and 87 by means of connections 88, 89 and 88a, 89a. The valves and couplings are also shown in FIG.

1.First

Stemplet 81, der ses i detaljer i fig. 5, indeholder en ventilklap 90, der kan glide i et hulrum 91 i stemplet 81, og som af en fjeder 92 holdes i den i fig. 8 viste stilling ("oppe11)· Et dæksel 93, der sikrer forbindelsen mellem stempellegemet 81 og stempelstangen 82, er gennembrudt af åbninger 94, der sætter hulrummet 91 i forbindelse med det ydre.The piston 81, seen in detail in FIG. 5, includes a valve flap 90 which can slide into a cavity 91 of the piston 81 and which is held by a spring 92 in the embodiment of FIG. 8 (cover 11) · A cover 93 securing the connection between piston body 81 and piston rod 82 is pierced by openings 94 which connect cavity 91 to the exterior.

Stemplet 81 har desuden en åbning, der sætter den øverste del af cylinderen 80 i forbindelse med hulrummet 91. På ventilklappen er der anbragt pakninger 95 for at sikre tætning mellem hulrummet 91 og den øvre del af cylinderen, når ventilklappen er i den viste stilling. Skrå kanaler 96 sætter hulrummet 91 i forbindelse med den nedre del af cylinderen. Pakninger 98 samvirker med en krave 99, der forlænger den hule stang for at sikre tætning mellem det uden for stemplet 81 liggende og det indre af den hule stang, når ventilen er i nederste stilling (J'nede").In addition, the piston 81 has an opening which connects the upper part of the cylinder 80 with the cavity 91. On the valve flap seals 95 are provided to ensure sealing between the cavity 91 and the upper part of the cylinder when the valve flap is in the position shown. Inclined channels 96 connect cavity 91 to the lower portion of the cylinder. Gaskets 98 cooperate with a collar 99 which extends the hollow rod to ensure sealing between the outside of the piston 81 and the interior of the hollow rod when the valve is in the lower position (J'nede ").

Styringen virker på følgende måde: Åbning af dækslet: I begyndelsesstadiet ligger pladen 13 an mod kraven 12; stemplet 81 ligger an mod bunden 80a af cylinderen; blæren er i forbindelse med den fri luft gennem den hule stempelstang 82, åbningerne 94, åbningen 83 og ventilen 86, som ikke er forbundet til kilden 56. Ventilklappen 90 er i den i fig. 5 viste stilling.The guide operates as follows: Opening the cover: At the initial stage, plate 13 abuts against collar 12; piston 81 abuts bottom 80a of cylinder; the bladder is in connection with the free air through the hollow piston rod 82, the openings 94, the opening 83 and the valve 86 which are not connected to the source 56. The valve flap 90 is in the embodiment shown in FIG. 5.

For at åbne dækslet sætter man kilden 56 i forbindelse med ventilen 86 gennem en af tilslutningerne 89 eller 89a.To open the cover, the source 56 is connected to the valve 86 through one of the connections 89 or 89a.

5 U58745 U5874

Den komprimerede luft løber gennem åbningerne 94, passerer gennem den hule stang 82 og oppuster blæren 12, hvorved den hæver pladen 13. Når trykket når en passende størrelse, og når pladen er hævet tilstrækkeligt, bevæger stemplet 81 sig over til endefladen 80b, idet det medfører overstykket 18, hvorved tankens åbning 11 blottes.The compressed air flows through the openings 94, passes through the hollow bar 82 and inflates the bladder 12, thereby raising the plate 13. When the pressure reaches a suitable size and when the plate is sufficiently raised, the piston 81 moves over to the end surface 80b, causes the top piece 18, thereby exposing the opening 11 of the tank.

Så frakobles kilden 56 fra ventilen 86, blæren tømmes, og pladen 13 fjerner sig fra overstykket 18 ved fjedrenes påvirkning.Then, source 56 is disconnected from valve 86, bladder empties, and plate 13 removes from top 18 by spring action.

Lukning af dækslet:Closure of the cover:

Ventilen 87 forbindes med kilden 57 ved en af tilslutningerne 88 eller 88a.Valve 87 is connected to source 57 at one of terminals 88 or 88a.

Ventilklappen 90 skifter stilling til stillingen "nede11. Den komprimerede luft kan kun bevæge sig gennem hulrummet 91, kanalerne 96 og den hule stang; blæren oppustes således; denne oppustning medfører, at pladen 13 nærmer sig overstykket 18. Når trykket i blæren når trykket i kilden, bevæger stemplet 81 sig i cylinderen, idet det medfører pladen 13 og overstykkerne 18 og 66.The valve flap 90 changes position to position "down" 11. The compressed air can only move through the cavity 91, the ducts 96 and the hollow rod; the bladder is inflated thus; this inflation causes the plate 13 to approach the head 18. When the pressure in the bladder reaches the pressure of source, the piston 81 moves in the cylinder, causing the plate 13 and the tops 18 and 66.

Når lukkemekanismen er på plads over åbningen 11, afbrydes forbindelsen 58-87; ventilklappen vender tilbage til stilling "oppe*1, og blæren tømmes gennem den hule stang, åbningerne 94, åbningen 83 og ventilen 86. Fjedrene trykker så pladen 13 mod kraven 11.When the closure mechanism is in place over the opening 11, the connection 58-87 is disconnected; the valve flap returns to position "up * 1" and the bladder empties through the hollow rod, openings 94, opening 83, and valve 86. The springs then press plate 13 against collar 11.

Forbindelserne mellem kilderne for komprimeret luft 56 og 57 og ventilerne 86 og 87 kan etableres manuelt af en operatør, der står på jorden. For at han skal kunne udføre tilkoblingen uanset vognens stilling i forhold til kilderne for komprimeret luft, findes der to tilslutninger til komprimeret luft 89 og 89a til åbning og to tilslutninger 88 og 88a til lukning. Disse tilslutninger er anbragt på hver sin side af tanken, således at de kan nås fra jorden. Der er således frembragt et åbne- og lukkesystem for dækslet, som ikke nødvendiggør adgang til tankens top.The connections between the sources of compressed air 56 and 57 and the valves 86 and 87 can be established manually by an operator on the ground. In order for him to be able to make the connection regardless of the position of the carriage with respect to the sources of compressed air, there are two connections for compressed air 89 and 89a for opening and two connections 88 and 88a for closing. These connections are located on either side of the tank so that they can be reached from the ground. Thus, an opening and closing system has been provided for the cover which does not require access to the top of the tank.

Kilderne for komprimeret luft kan være installeret på optankningsstedet; de er da forsynet med et tilkoblingsrørsystem, der tillader etablering af forbindelsen med tilslutningerne på tanken.The sources of compressed air may be installed at the refueling point; they are then provided with a connection pipe system which allows the connection to be established with the connections on the tank.

Som udførelseseksempel på opfindelsen er der valgt en jernbanetankvogn.As an exemplary embodiment of the invention, a railway tanker truck has been selected.

Det er klart, at opfindelsen også kan anvendes til tankbiler og til andre tanke af enhver art.It is to be understood that the invention can also be applied to tank cars and to other tanks of all kinds.
