Internationalt Patent-Bur eau.___ (64) Klappr am med et bæreorgan for et drivaggregat.International Patent Office ___ (64) Folding frame with a carrier for a drive assembly.

Opfindelsen vedrører en klappram med skroghalvdele, der kan svinges ud til siden om en i forhold til prammens længdeakse parallel akse, og et bæreorgan for et drivaggregat, der altid holdes i vandret stilling af bæreorganet.BACKGROUND OF THE INVENTION The invention relates to a flap frame with hull halves which can be swung to the side about a parallel axis to the longitudinal axis of the barge, and a carrier for a drive assembly which is always held in a horizontal position by the carrier.

Skroghalvdelene benævnes i det følgende også klapper.The hull halves are hereinafter also referred to as flaps.

Der findes kendte klappramme, hvor drivaggregatet er forbundet med den ene klap med et fast, af tappe og taplejer bestående lænkeledsystem, og er tværforskydeligt forbundet med den anden klap.There are known flap frames in which the drive assembly is connected to one flap with a fixed, linkage and stud bearing linkage system, and is transversely connected to the other flap.

Ved dette system holdes bæreorganet eller platformen ikke vandret.In this system, the carrier or platform is not kept horizontal.

Der findes også kendte klappramme, hvor platformen, der ganske vist ikke bærer noget drivaggregat, holdes vandret ved hjælp af en lodret, søjleagtig styring, der er forbundet med klapperne ved 1 Λ 1480 2 hjælp af forbindelsesstænger. En sådan kendt klappram benytter ligeledes en lodret styring til at bære platformen, men ved denne klappram er den af styringen og platformen dannede enhed ikke forbundet med klapperne ved hjælp af forbindelsesstænger, men ved hjælp af kulissestyr. Navnlig ved den mod hækken eller boven vendende side af aggregatet eller platformen virker en lodret styreliste eller søjle til styring forstyrrende.There are also known flap frames, in which the platform, which does not carry any powertrain, is held horizontally by a vertical, column-like guide, which is connected to the flaps by 1 Λ 1480 2 by means of connecting rods. Such a known flap frame also uses a vertical guide to support the platform, but in this flap frame the unit formed by the control and the platform is not connected to the flaps by connecting rods, but by backstop. Especially at the rear or top of the unit or platform, a vertical guide rail or column for steering is disturbing.

Med opfindelsen tilsigtes det at holde drivaggregatet og bæreorganet eller platformen vandret, når klapperne åbnes, uden at det er nødvendigt at have et særligt styr, f.eks. i form af en lodret stang.The invention aims to keep the drive unit and the carrier or platform horizontal when the flaps are opened without the need for a special guide, e.g. in the form of a vertical rod.

Opgaven løses ifølge opfindelsen ved, at bæreorganet er hængselforbundet med begge skroghalvdelene i faste punkter på disse, og at der er et længdevariabelt forbindelsesorgan mellem de to faste punkter. Herved sikres det, at aggregatets midterplan, når det før udsvingningen af klapperne falder sammen med prammens midterplan, ved udsvingningen stadig forbliver parallel med vinkelhalveringslinien i de udsvingende pramhalvdele.The task is solved according to the invention in that the carrier is hingedly connected to both hull halves at fixed points thereon and that there is a longitudinal variable connecting member between the two fixed points. This ensures that the median plane of the unit, when it coincides with the median plane of the barge before the swinging of the flaps, remains still parallel to the angular half-line in the swinging barge halves.

Der byder sig flere forskellige muligheder for gennemførelse af opfindelsen. Således kan f.eks. bæreorganet bestå af mindst to dele, der er lejret på hver sin skroghalvdel i hængsler og griber teleskopagtigt ind i hinanden. Denne udførelsesform giver en meget enkel opbygning.Several possibilities exist for the practice of the invention. Thus, e.g. the support means consists of at least two parts, which are mounted on each hull half in hinges and telescopically engage one another. This embodiment provides a very simple structure.

En anden udførelsesform for opfindelsen består i, at drivaggregatet understøttes af mindst ét stangpar, der i hovedsagen består af to stænger, der krydser hinanden, og som dels er forbundet med de to skroghalvdele i hængsler, dels er forbundet med aggregatet eller bæreorganet ved hjælp af hængsler, der er indbyrdes forskydeligt monteret, hvorhos de to stænger indbyrdes er forbundet sakseagtigt i krydsningspunktet.Another embodiment of the invention consists in that the drive assembly is supported by at least one pair of bars, consisting essentially of two interconnecting rods, which are connected in part to the two hull halves in hinges, and are connected in part to the assembly or carrier. hinges which are slidably mounted mutually, wherein the two rods are interconnected scissor-wise at the point of intersection.

Drivaggregatet eller bæreorganet er fortrinsvis hængselforbundet med to, ved ikke udsvingede skroghalvdele parallelle, stænger, som igen er hængselforbundet med hver sin skroghalvdel, og at den mod den ene skroghalvdel vendende side af aggregatet eller bæreorganet er hængselforbundet med den anden skroghalvdel ved hjælp af mindst én stang, idet beliggenheden af hængslerne og længderne af stængerne er således afstemt efter hinanden, at aggregatet eller bæreorganet parallelforskydes ved svingning af skroghalvdelene.The drive assembly or carrier is preferably hingedly connected by two, non-pivoted hull halves parallel, rods which in turn are hingedly connected to each hull half, and the at least one side of the assembly or carrier is hingedly connected to the other hull half at least. rod, the position of the hinges and lengths of the rods being aligned so that the assembly or carrier is displaced in parallel by pivoting the hull halves.

Ifølge endnu en udførelsesform for opfindelsen danner aggregatet eller dets bæreorgan, stængerne og skroghalvdelene med hæng- 3 1Λ1480 sierne stangfirkanter, der har en stang fælles.According to yet another embodiment of the invention, the assembly or its support member, the rods and hull halves form hanging squares having a rod in common.

Klapprammen ifølge opfindelsen kan have en motor til forskydning af bæreorganets dele i forhold til hinanden.The flap frame according to the invention may have a motor for displacing the parts of the carrier relative to each other.

Opfindelsen forklaresnærmere i det følgende under henvisning til tegningen, hvor fig. 1 skematisk viser en klappram set ovenfra, fig. 2 skematisk klapprammen ifølge fig. 1 set fra siden, fig. 3 konstruktionen ifølge opfindelsen med lukkede klapper, fig. 4 konstruktionen ifølge fig. 3 med åbnede klapper, fig. 5 skematisk udførelsesformen for opfindelsen ifølge fig. 3 og 4 suppleret med et drivorgan, fig. 6 skematisk en anden udførelsesform for opfindelsen, fig. 7 skematisk en yderligere udførelsesform for opfindelsen med lukkede klapper. Forbindelsesstængerne er kun antydet symbolsk med linier og hængslerne med punkter, og fig. 8 udførelsesforraen ifølge fig. 7 med åbnede klapper.BRIEF DESCRIPTION OF THE DRAWINGS The invention will be explained in more detail below with reference to the drawing, in which: FIG. 1 is a schematic top plan view of FIG. 2 schematically shows the flap frame according to FIG. 1 is a side view; FIG. 3 shows the closed flap structure according to the invention; FIG. 4 the construction of FIG. 3 with opened flaps; FIG. 5 shows schematically the embodiment of the invention according to FIG. 3 and 4 supplemented with a driving means; FIG. 6 schematically shows another embodiment of the invention; FIG. 7 schematically shows a further embodiment of the invention with closed flaps. The connecting rods are only indicated symbolically by lines and the hinges by points, and fig. 8 shows the embodiment of FIG. 7 with opened flaps.

Fig. 1 viser skematisk en klappram set ovenfra. Skroget er delt på langs på midten, så at det består af to halvdele 10 og .11.FIG. 1 is a schematic top view of a flap frame. The hull is split longitudinally along the middle so that it consists of two halves 10 and .11.

De to halvdele er på kendt måde holdt sammen i nærheden af dækket på en sådan måde, at de kan svinge ud til siden og åbne sig nedad.The two halves are in a known manner held together near the tire in such a way that they can swing out to the side and open downwards.

Disse halvdele skal derfor i det følgende betegnes med klapper. Konstruktionen af disse klapper inklusive luftkasser, hængsler og drivorganer til klapperne er kendt og skal ikke nærmere beskrives med undtagelse af en udførelsesform, hvor mekanismen til at bære driv-aggregatet ifølge opfindelsen kan anvendes til at drive klapperne. Ved fartøjets hæk 12 er der på dækket et drivaggregat 13, der i hovedsagen består af en motor 14, kraftoverføringsorganer, brændstof tilførselsanlæg, en rorpropeller 15 Og et styrehus 16. Klapprammen kan også drives af en almindelig propeller, f.eks. gennem et såkaldt z-drev og styres med et pladeror. Rorpropellere er imidlertid særlig fordelagtige. For at rorpropelleren 15 eller z-drevet kan anbringes på den bedste måde, er prammens hæk forsynet med en udskæring 17. I tilfælde af at der også skal være en rorpropeller ved boven 18, kan der også være en udskæring 19, der er vist punkteret i fig. 1.These halves must therefore be denoted by flaps. The construction of these flaps including air boxes, hinges and drive means for the flaps is known and will not be further described with the exception of one embodiment in which the mechanism for carrying the drive assembly according to the invention can be used to drive the flaps. At the stern 12 of the vessel there is on the deck a drive assembly 13, consisting essentially of an engine 14, power transmission means, fuel supply system, a rudder propeller 15 and a wheelhouse 16. The flap frame can also be operated by a conventional propeller, e.g. through a so-called z-drive and controlled with a plate rudder. However, rudder propellers are particularly advantageous. In order that the rudder propeller 15 or the z-drive can be positioned in the best way, the barge's stern is provided with a cut-out 17. In the event that there is also a rudder propeller at the upper 18, there may also be a cut-out 19 shown punctured. in FIG. First

Figurerne 3 og 4 viser en udførelsesform for opfindelsen.Figures 3 and 4 show an embodiment of the invention.

De to klapper 10 og 11, der holdes sammen med et hængsel 20, bærer 4 141480 ved hjælp af et stangsystem med taplejer 21, 22 og tappe 23, 24 en platform 25, der består af to halvdele 27 og 28. Platformen bærer drivaggregatet 13. De to halvdele af platformen er sammenføjet således med hinanden, at deres længde kan varieres teleskopagtigt.The two flaps 10 and 11 held together with a hinge 20 carry 4 141480 by means of a rod system with pin bearings 21, 22 and pins 23, 24 a platform 25 consisting of two halves 27 and 28. The platform carries the drive assembly 13 The two halves of the platform are joined together so that their length can be varied telescopically.

Når således de to klapper åbnes, således som det er vist skematisk i fig. 4, for at udtømme det opgravede materiale kan de to halvdele af platformen optage forandringen af afstanden mellem hængselleddene ved, at de skyder sig ind i hinanden. Drivaggregatets midterplan, der falder sammen med klapprammens midterplan før udsvingningen, forbliver ifølge opfindelsen under udsvingningen parallel med vinkelhalveringslinien i den vinkel, som klappernes dæk danner, det vil sige platformen holdes stadig vandret.Thus, when the two flaps are opened, as shown schematically in FIG. 4, to exhaust the excavated material, the two halves of the platform can accommodate the change of the distance between the hinge joints by sliding into each other. The median plane of the drive assembly, which coincides with the median plane of the flap frame before the oscillation, remains according to the invention during the oscillation parallel to the angle bisector at the angle formed by the tire's tires, that is, the platform is still held horizontally.

Fig. 5 viser en udførelsesform af konstruktionen ifølge fig.FIG. 5 shows an embodiment of the construction according to FIG.

3 og 4, der består i, at den ene platformhalvdel 27' er forsynet med en cylinder 29, og at den anden halvdel 28' er forsynet med et stempel 30. Ved at føre et trykmiddel ind i cylinderkammeret 32 og udtømme det andet kammer 31 ved hjælp af ledninger 33, 34 kan klapperne åbnes eller åbningen understøttes. I stedet for et hydraulisk eller et pneumatisk drivorgan kan der også anvendes mekaniske eller elektriske drivorganer.3 and 4, comprising the one half of the platform 27 'being provided with a cylinder 29 and the other half 28' being provided with a piston 30. By inserting a pressure means into the cylinder chamber 32 and discharging the second chamber 31 by means of wires 33, 34 the flaps can be opened or the opening supported. Instead of a hydraulic or a pneumatic drive means, mechanical or electrical drive means can also be used.

Fig. 6 viser en yderligere fordelagtig udførelsesform for opfindelsen, hvor drivaggregatet 13 eller platformen 35, der bærer dette, bæres på de to klapper 10 og 11 af i det mindste to stænger 36, 37, der skærer hinanden sakseagtigt, og som er forbundet med hinanden i krydsningspunktet med en tap 38. Stængerne er ifølge opfindelsen forbundet med klapperne og platformen i hængsler 39, 40, 41, 42, der består af tappe og taplejer. Når klapperne 10 og 11 åbnes, som det eksempelvis er vist i fig. 4, forskyder mindst ét af hængslerne 40, 41 sig i et styr på platformen.FIG. 6 shows a further advantageous embodiment of the invention, in which the drive assembly 13 or the platform 35 carrying it is carried on the two flaps 10 and 11 by at least two shears 36, 37 which intersect each other with scissors and which are connected to each other in the point of intersection with a pin 38. According to the invention, the rods are connected to the flaps and the platform in hinges 39, 40, 41, 42, which consists of pins and pin bearings. When the flaps 10 and 11 are opened, as shown for example in FIG. 4, at least one of the hinges 40, 41 moves in a guide on the platform.

En yderligere, meget fordelagtig udførelsesform for opfindelsener vist i fig. 7 og 8. Konstruktionen er skematisk, idet de stang-formede elementer er vist som streger, og hængslerne er vist som punkter. Drivaggregatet 13 eller platformen 43, der bærer dette, er forbundet med klapperne 10, 11 ved hjælp af et system, der består af to stangfirkanter 44, 45. Kinematisk udgør platformen 43 og klappernes dæk 46, 47 stænger. Hængslet 20, der er forbundet med klapperne, tæller med til hængslerne. En af stangfirkanterne består af dækket af klappen 10 (stangen 46), hængslet 20, dækket af klappen 11 (stangen 47), hængslet 50 på dækket, stangen 48, hæng-A further, very advantageous embodiment of the invention shown in FIG. 7 and 8. The construction is schematic in that the rod-shaped elements are shown as lines and the hinges are shown as points. The drive assembly 13 or the platform 43 carrying this is connected to the flaps 10, 11 by means of a system consisting of two rod squares 44, 45. Kinematically, the platform 43 and the tires 46, 47 of the flaps form. The hinge 20 associated with the flaps counts for the hinges. One of the rod squares consists of the tire of flap 10 (rod 46), hinge 20, tire of flap 11 (rod 47), hinge 50 on tire, rod 48, hinge.

Claims

5, the rod 55 which is hinged on the deck of the flap 10 by the hinge 54. The second rod square consists of the aforementioned hinge 54, the said rod 55, the said hinge 51, the platform (the rod 43), the hinge 52, the rod 49 fixed by the hinge 53 on the tire of the flap 10 and the portion of the tire of the flap 10 (the rod 46 ') lying between the hinges 53 and 54. The length of the common rod 55 and its point of attack 54 on the tire 10 is selected according to the invention such that the rod 48 is pivoted so much that the rod 49 is pivoted just as much to the other side because of the connection through the rod 43 when the rods 46 and 47 are pivoted into the hinge 20. Thus, the rod 43 (the platform) remains horizontal. This principle is also implemented with the other bar lengths. Bars 48 and 49 need not be vertical but may be inclined. Importantly, the length of the rod 55 and the location of the hinge 54 are selected accordingly. In general, there are two systems according to FIG. 7 to 8 to support the drive assembly, namely a system at the rear end and one at the upper end of the assembly or platform. In this case, it is advantageous for the two rods 55 to intersect. When talking about at least one element, e.g. rod 55, is common to the two rod squares, so this relates only to the ideal system. In the real embodiment, e.g. the elements 46, 47, 48 and 55 lie in a different plane than the elements 43, 49 and 46 ', so that it is not clear which elements are common. According to the invention, it is essential that the rod 55 is connected on one side to a hinge 54 which sits on one flap and on the other side is connected to a rod 48 arranged on the other flap so that the rod 48 is swung outwards by swinging the flap. In the illustrated embodiments, the drive means for opening and closing the flaps where known are not shown and described. For example, the drive means may consist of at least one hydraulic cylinder disposed between the flaps, for example with a horizontal longitudinal axis.

A folding frame with hull halves, which can be swung to the side about a parallel axis of the barge's longitudinal axis, and a carrier for a drive assembly (13), always held in a horizontal position by the carrier, characterized in that the carrier (25,
