Description

1 JARNVAGSVAGN FoRSEDD MED LOS LASTBARARE Uppfinningens omrade Uppfinningen avser en jdrnvdgsvagn enligt ingressen till patentkravet 1. FIELD OF THE INVENTION The invention relates to a railway carriage according to the preamble of claim 1.

Uppfinningens bakgrund Det man onskar av ett logistiksystem är att det ska ha hog effektivitet, hog flexibilitet, lag anskaffningskostnad, lag driftskostnad samt lag miljopaverkan. Background of the invention What is desired of a logistics system is that it should have high efficiency, high flexibility, legal acquisition cost, legal operating cost and legal environmental impact.

Jdrnvdgstransporter dr mojligen relativt miljOvdnliga, men de ovriga onskemalen uppfylls inte annat an majligen i speciella transportfall. Jarnvagsvagnar är istdllet tunga, pa bekostnad av lastkapaciteten, samt dyra i inkOp och drift. Rail transport may be relatively environmentally friendly, but the other requirements are not met except in special transport cases. Railway wagons are rather heavy, at the expense of load capacity, and expensive to purchase and operate.

Det Or ocksa mycket dyrt att bygga sjalva jarnvagen, vilket gOr att jdrnvdgstransporter sdllan kan gOras "fran dOrr till dorr". Det behovs darfor omlastningar, vilket avsevart okar den totala transporttiden samt risken for problem. Vid transporter mellan olika lander bar man dessutom ibland olika sparvidd, vilket ocksa innebdr omlastningar. It is also very expensive to build the railway itself, which means that rail transport can thus be done "from door to door". Transhipments are therefore needed, which significantly increases the total transport time and the risk of problems. In transport between different countries, they also sometimes carried different savings, which also means transhipments.

En annan stor orsak till jdrnvdgens nackdelar bar sin grund i att jarnvagsvagnar är dyra att tillverka och typgodkanna samt tillverkas for ett specifikt anvdndningsomrade for en mycket lang livslangd, normalt 30 dr. Denna livslangd Or sa Lang, att det inte Or mOjligt att ha en detaljerad kunskap cm transportbehoven for sa lang tid framat. Att skaffa jdrnvdgsvagnar innebdr saledes en mycket stor ekonomisk risk. Another major reason for the disadvantages of the railway was due to the fact that railway carriages are expensive to manufacture and type approved and are manufactured for a specific area of use for a very long service life, normally 30 dr. This lifespan Or said Lang, that it is not possible to have a detailed knowledge of the transport needs for such a long time to come. Acquiring underground carriages thus entails a very large financial risk.

Jdrnvdgsvagnar utformas ddrfor ofta far sa manga anvandningsomraden som mojligt. Det leder till att vagnar i slutanden sdllan Or optimala far sitt dndamal. 2 I manga fall med speciella godstyper, kan man inte ens overvaga jarnvagstransporter, da det inte finns vagnar for denna typ av gods och det for varje enskild anvandare i manga fall är for dyrt och tidskravande att utveckla helt nya vagnar fran grunden fOr ett specifikt behov. I andra fall kan man kanske t.ex. inte utnyttja mojligheten till att en viss banstrackning klarar en stOrre vagnsvikt, ell just denna typ av vagn kanske inte finns tillganglig. Jdrnvdgs wagons are therefore designed for as many areas of use as possible. This leads to carriages in the closing sdllan Or optimal get their dndamal. 2 In many cases with special types of goods, it is not even possible to monitor rail transport, as there are no wagons for this type of goods and for each individual user it is in many cases too expensive and time consuming to develop completely new wagons from the ground up for a specific need. . In other cases, you may e.g. do not take advantage of the possibility that a certain track stretch can handle a larger wagon weight, or this particular type of wagon may not be available.

Jarnvagsvagnarnas langa livslangd i kombination med att de utsatts for utmattningsbelastning, gor att de maste vara mycket gediget gjorda. Det gor dem tunga och clamed ytterligare dyrare. The long service life of railway wagons, combined with being subjected to fatigue loads, means that they must be made very solidly. It makes them heavy and clamed even more expensive.

Idag finns hoghallfasta stal med vars hjalp man potentiellt skulle kunna sanka vagnsvikterna. Tyvarr bar utmattningsbelastningen aven den nackdelen att man inte kan utnyttja fOrdelarna med dessa stalsorter. Today, there are hoghall-fixed stables with the help of which one could potentially lower the wagon weights. Unfortunately, the fatigue load also had the disadvantage that one could not take advantage of these steel types.

Far att kraftigt farbattra forutsattningarna far jarnvagstransporter skulle man behOva gora det mOjligt att enkelt andra jarnvagsvagnar far olika fOrutsattningar och bruk, drastiskt minska behovet av omlastningar samt gara dem lattare och darmed billigare genom att minimera de utmattningsbelastade delarna. In order to greatly improve the conditions for rail transport, it would be necessary to make it possible for other railway carriages to easily have different conditions and uses, drastically reduce the need for transhipments and make them lighter and thus cheaper by minimizing the fatigue-laden parts.

Transport av bulkformigt gods ger sarskilda utmaningar i det att det Or svart att kombinera en konstruktionsmassigt enkel och darmed billig och underhallsvanlig jarnvagsvagn, med en kostnadseffektiv metod att lossa godset. Transport of bulk goods presents special challenges in that it is difficult to combine a structurally simple and thus cheap and maintenance-ordinary railway wagon, with a cost-effective method of unloading the goods.

En losning Or att anvanda botten- eller sidotammande vagnar. A solution Or to use bottom or side taming trolleys.

Detta gor dock varje vagn extra komplicerad med rarliga luckor. Har man ett stort antal vagnar innebar detta en avsevard extra kostnad jamfort med vagnar utan luckor. 3 Luckorna medfar aven extra underhallskostnader och risk far att mekanismerna karvar. Dessutom blir varje vagn tyngre pa bekostnad av lastkapaciteten. However, this makes each carriage extra complicated with nice doors. If you have a large number of carriages, this meant a considerable extra cost compared to carriages without doors. 3 The doors also entail extra maintenance costs and there is a risk that the mechanisms will crack. In addition, each wagon becomes heavier at the expense of the load capacity.

Det billigaste sattet att transportera bulkmaterial pa jdrnvdg, dr att anvdnda enklaste tdnkbara vagn, i princip en lada pa hjul. Detta minimerar kostnaden for inkop och underhall. Problemet dr att dessa vagnar dr svara att -Lama pa ett kostnadseffektivt satt. The cheapest way to transport bulk material on the ground floor is to use the simplest conceivable trolley imaginable, in principle a barn on wheels. This minimizes the cost of purchasing and maintenance. The problem is that these carriages respond to -Lama in a cost-effective way.

Idag finns i princip tva sdtt att tOmma sadana vagnar. Det ena ar att anvanda en gravmaskin. Denna lasning dr dock tidskrdvande och gar hart At vagnarna. Ett annat sdtt dr att anvanda en s.k. vagnsvandare. Vagnsvandare fungerar pa sa satt att de tommer vagnarna genom att rotera hela vagnen tillsammans med den del av ralsen pa vilken vagnen star. Dessa maskiner dr dock mycket dyra i inkap och underhall. Dessutom maste varje vagn vara forsedd med dyra och kansliga roterbara koppel. Sadana är inte ens godkamda i Europa. Dessutom har lasningen nackdelen av att det ar farligt att rensa vagnar med kladdande last, cid detta sker med vagnarna uppochner. Det kravs aven sarskilda, dyra maskiner far positionering av vagnssdttet, cid loket inte kan positionera vagnarna lossningsstationen med den precision som kravs. Today, there are basically two ways to empty such carts. One is to use an excavator. However, this loading is time consuming and goes hard on the wagons. Another way is to use a so-called wagon wanderers. Trolley wanderers work in such a way that they empty the trolleys by rotating the entire trolley together with the part of the rail on which the trolley stands. However, these machines are very expensive to cut and maintain. In addition, each trolley must be equipped with expensive and durable rotatable leashes. Sadana is not even approved in Europe. In addition, the loading has the disadvantage that it is dangerous to clean wagons with sticky loads, as this happens with the wagons upside down. Special, expensive machines are also required for positioning the wagon seat, as the locomotive cannot position the wagons unloading station with the precision required.

Genom US 1940732 dr en jdrnvdgsvagn kdnd, vars lastbdrare kan tippas at sidan medelst en hydraulcylinder, som ar anordnad att verka pa lastbdrarens ena langsida. En vridningsaxel, kring vilken lastbararen dr inrattad att tippas, Or emellertid beldgen pa jdrnvdgsvagnens stomme, vilket medfar att lastkorgen inte kan tippas i sa stor vinkel som Or anskvart, sdrskilt vid kladdande last. By US 1940732 a ground carriage is drawn, whose load carrier can be tipped to the side by means of a hydraulic cylinder, which is arranged to act on one long side of the load carrier. A pivot axis, around which the load carrier is arranged to be tipped, is, however, the bellows on the body of the grounding trolley, which means that the load basket cannot be tipped at as great an angle as Or is required, especially in the case of loading loads.

Genom DE 1151219 B ãr det kdrit en anordning for tomning av en pA en jdrnvdgsvagn lost uppburen lastbdrare genom vridning av densamma. DE 1151219 carries a device for emptying a load carrier carried on a railway carriage by turning it.

Beskrivning av foredragna utforingsformer I nedanstaende beskrivning och patentkrav anvdnds uttrycket boggi men det är uppenbart for fackmannen att boggin kan ersdttas av ett hjulpar. Description of Preferred Embodiments In the following description and claims, the term bogie is used, but it will be apparent to those skilled in the art that the bogie can be replaced by a pair of wheels.

SAsom angivits ovan är syftet med uppfinningen att Astadkomma ett enkelt och billigt system som mojliggOr lossning av en lastbdrare samt en enkel och billig transportanordning in- nefattande lastbLraren. As stated above, the object of the invention is to provide a simple and inexpensive system which makes it possible to unload a load carrier and a simple and inexpensive transport device including the load carrier.

Transportanordningen/vagnen skall i princip hantera tvA stora krafter, den ena är tAgkrafterna, dvs. drag- och tryckkrafter och den andra är att bdra upp lasten. Hos transportanordningen enligt uppfinningen har ddrfor dessa tvA krafter delats upp pd. tvA separata komponenter - dragstAng respektive en sjdlvbdrande lastbdrare. Lastbdrarens tyngd Overfars ner till hjulen via dragstAngen pd punkter rakt ovanfor de punkter ddr denna har stod frAn hjulen. Tyngden frAn lastbdraren gAr p1 sA sdtt kortast majliga vdg genom dragstAngen och utan att bOjbelasta densamma. Det rdcker i princip med f5rstyvande skott i dragstAngen far att klara av detta. Far att fA ner vagnens totala hojd, kan lastbdrarens bdrande element utformas som tvA balkar som placeras pA var sin sida av dragstAngen. The transport device / trolley must in principle handle two large forces, one is the train forces, ie. tensile and compressive forces and the other is to carry the load. In the transport device according to the invention, therefore, these two forces have been divided. TWO separate components - drawbar and a self-supporting load carrier. The weight of the load carrier is transferred down to the wheels via the drawbar at points directly above the points where it has stood from the wheels. The weight from the load carrier is thus the shortest oral route through the drawbar and without bending the same. In principle, stiffening shots in the drawbar are enough to cope with this. In order to reduce the total height of the trolley, the load-bearing elements of the load carrier can be designed as two beams which are placed on each side of the drawbar.

Far balansens skull kommer dessutom lastbdraren att antingen stOdja mot, eller vid behov, kunna stOdja sig mot sidostOd pd boggin/hjulen. For the sake of balance, the load carrier will also be able to either support or, if necessary, be able to support the lateral support on the bogie / wheels.

Lastbdraren star i princip helt last p1 underredet, men kan vid behov ldsas vid detta. For att hindra oanskad farskjutning i ldngsled kan langsstopp 2a t.ex. i form av klackar pd. 8 dragstangen, vara anordnade, se Fig. 13. Detta ldngsstopp kan samverka med t.ex. en ldmpligt placerad tvdrbalk pa undersidan av lastbdraren. PA motsvarande sift hindras oanskade glidningar i sidled. The load carrier is in principle completely loaded on the chassis, but can be loaded if necessary. In order to prevent undesired longitudinal shipping in the longitudinal direction, longitudinal stop 2a can e.g. in the form of heels pd. 8 the drawbar, be arranged, see Fig. 13. This length stop can cooperate with e.g. a properly placed double girder beam on the underside of the load carrier. PA corresponding sieve prevents unwanted lateral slips.

Genom att de tva olika huvudkrafterna tas upp av separata konstruktionsdelar är det enklare att optimera utformningen av dessa for sina respektive lastfall, jdmfort med om de hade varit integrerade med varandra. Delarna kan dven ges en mindre komplex utformning, vilket starkt underldttar hallfasthetsberdkning och tillverkning. De kan pa sa sdtt garas exakt lagom starka far att ta upp de erforderliga krafterna. Because the two different main forces are absorbed by separate structural parts, it is easier to optimize the design of these for their respective load cases, even if they had been integrated with each other. The parts can also be given a less complex design, which greatly facilitates half-strength coating and manufacturing. In this way, they can be equipped with exactly the right strength to absorb the required forces.

Genom att lastbdraren i princip är lostagbar och sjdlvbdrande, kan denna lyftas av fran vagnen. Det ger flera mycket stora fardelar. T.ex. kan man vdlja att utforma lastbdraren fbr kortare livsldngd an underredet. Det g6r att lastbdraren kan garas ldttare, vilket gor att man kan frakta mer gods vid varje transport och pa sa sdtt tjdna in den eventuella extra kostnad som uppstar pa grund av att man maste byta lastbdrare oftare an om den hade ldngre livsldngd. Because the load carrier is in principle detachable and self-supporting, it can be lifted off the trolley. It provides several very large parts. For example. you can choose to design the load carrier for a shorter service life than the chassis. This means that the load carrier can be stored lighter, which means that you can carry more goods with each transport and thus earn any additional costs that arise due to having to change load carriers more often than if it had a longer service life.

Vidare är det mojligt att ddmpa lastbdraren fran utmattande vibrationer i underredet. Det innebdr att det endast Or hjulen med kringutrustning samt den minimala dragstangen som kommer att vara utmattningsbelastade medan en stor del av vagnen - lastbdraren - inte kommer att vara det. Lastbdraren kan ddrmed tillatas utsdttas for flera ganger sa stor belastning och kan ddrfOr goras ytterligare avsevdrt mycket ldttare. Furthermore, it is possible to dampen the load carrier from exhausting vibrations in the chassis. This means that only the wheels with peripheral equipment and the minimal drawbar will be fatigued, while a large part of the trailer - the load carrier - will not be. The load carrier can thus be allowed to be subjected to several times as large a load and can therefore be made considerably much lighter.

Av samma orsak kan man anvdnda och dra full nytta av fardelarna med de hoghallfasta stalsorternas styrka i lastbdraren. Ddrigenom kan denna av ytterligare en anledning garas mycket ldttare. 9 Ett icke begrdnsande exempel pa en transportanordning/vagn 1 visas i Fig. 1-6 varvid det framgar att densamma innefattar en stomme 2 avsedd i forsta hand for upptagande av drag- och tryckkrafter, vilken stomme är forbunden med och uppburen vid minst en punkt av respektive boggi 4a,4b vid respektive dnden has stommen, och en lastbdrare 3. I den visade utforingsformen innefattar stommen en langstrdckt dragstang 2. Lastbdraren 3 Or forsedd med en ramkonstruktion, som kan omfatta med varandra sammanbundna bottenbalkar 50, sidobalkar 53 och en lastbdrande toppbalk 54 (Fig. 6), avsedd att uppta tyngden av lastbdraren och den av lastbdraren uppburna lasten och att overfara densamma till mitt Over respektive boggi. Bottenbalkarna 50 Or placerade pi var sida am dragstangen 2 och Or forsedda med stadorgan 51 avsedda att st5dja mot komplementdra stodorgan 52 placerade ungefdr vid mitten av respektive boggi 4a,4b. Lastbdraren är kring sin 5vre omkretskant farsedd med den lastbdrande toppbalken 54. Faretrddesvis Or ingreppspunkterna 6a,6b farbundna med sidobalkarna 53. For the same reason, you can use and take full advantage of the car parts with the strength of the high-strength steel types in the load carrier. As a result, for another reason, this can be made much lighter. A non-limiting example of a transport device / carriage 1 is shown in Figs. 1-6, it being seen that it comprises a body 2 intended primarily for absorbing tensile and compressive forces, which body is connected to and supported at at least one point of the respective bogie 4a, 4b at the respective end has the frame, and a load carrier 3. In the embodiment shown, the frame comprises an elongated drawbar 2. The load carrier 3 Or is provided with a frame construction, which may comprise interconnected bottom beams 50, side beams 53 and a load bearing top beam 54 (Fig. 6), intended to take the weight of the load carrier and the load carried by the load carrier and to transfer it to the middle of the Over respective bogie. The bottom beams 50 Or are placed on each side of the drawbar 2 and Or are provided with support members 51 intended to support complementary support members 52 located approximately at the center of the respective bogies 4a, 4b. The load carrier is fitted around its upper circumferential edge with the load-bearing top beam 54. Optionally, the engaging points 6a, 6b are connected to the side beams 53.

I Fig. 9 är en schematisk sektionerad dndvy av en boggi med en schematisk visad tvdrbalk 55. Sidobalkarna 53 och tvdrbalken 55 är foretrddesvis inbordes forskjutna i vagnens ldngdriktning. I denna utf6ringsform Or bottenbalkarna 50 forsedda med sidostod 51a som vilar mot stodorgan 52, vilka strdcker sig i linje med och Or placerade mellan hjulparen i boggien 4a. Detta till skillnad mot Fig.6 ddr stodorganet 52 Or placerat innanfbr linjen fbr hjulparet. Vidare Or bottenbalkarna 55 p0 sin sida vdnd mot dragstingen 2 forsedda med styrorgan 56 Fbr att styra lastbdraren 3, di den placeras p0 vagnsunderredet/dragstangen. Dessa styrorgan 56 forhindrar Oven lastbdrarens forskjutning i sidled. In Fig. 9, a schematic sectional side view of a bogie with a schematically shown double girder beam 55 is shown. The side beams 53 and the double girder beam 55 are preferably offset inboard in the longitudinal direction of the carriage. In this embodiment, the bottom beams 50 are provided with side supports 51a resting against support members 52, which extend in line with and are placed between the wheel pairs in the bogie 4a. This is in contrast to Fig. 6 where the support member 52 is located inside the line in front of the pair of wheels. Furthermore, the bottom beams 55 on their side facing the drawbars 2 are provided with guide means 56 for guiding the load carrier 3, in which it is placed on the carriage base / drawbar. These guides 56 prevent the load carrier from moving laterally.

Genom att utforma vagnen 1 pA ovan ndmnt sdtt kan man utnyttja toppbalken 54 for att pd ett enkelt satt lyfta lastbararen mellan olika vagnsunderreden som i fallet med jarnvagsvagnar vilka kan ha olika spdrvidd, eller frdn jarnvag till lastbil/semi-trailer/dumper eller vice versa. By designing the wagon 1 pA as mentioned above, the top beam 54 can be used to easily lift the load carrier between different wagon undercarriages, as in the case of railway wagons which may have different spreading widths, or from a railway wagon to truck / semi-trailer / dumper or vice versa. .

Genom att utforma vagnen 1 pd detta satt kan olika ldnga lastbdrare placeras pd stommen, som i sddant fall har en ldngd anpassad efter lastbararen, sd lange som ingreppspunkterna 6a,6b averensstdmmer med den farsta 10 och andra 11 vandanord- ningen. By designing the trolley 1 in this way, different length load carriers can be placed on the frame, which in such a case has a length adapted to the load carrier, as long as the engagement points 6a, 6b correspond to the first 10 and other 11 water devices.

I de visade utforingsformerna är armarna 11a,11b has den andra vdndanordningen 11 visade svdngbara mellan ett aktivt och ett inaktivt ldge, men det är uppenbart att armarna 11a,11b kan utfora en vertikal rorelse mellan ett aktivt och inaktivt ldge eller vara stationdrt placerade i det aktiva ldget. In the embodiments shown, the arms 11a, 11b have the second turning device 11 shown pivotable between an active and an inactive layer, but it is obvious that the arms 11a, 11b can perform a vertical movement between an active and inactive layer or be stationary in the active ldget.

Det ar uppenbart fOr fackmannen att genom att lastbararen Or last anordnad p1 underredet kan densamma flyttas mellan olika tag/transportslag eller underreden med olika spArvidder. Lyften kan t.ex. garas med hjdlp av containertruckar, terminalkranar eller grensletruckar. Det gOr att man kan slippa en hel del omlastningar av gods. Ta som ett exempel ett fOretag, gruva eller kanske en skog som avverkas och som ligger en bit ifrdn en jdrnvdg. Dl kan man lasta i lastbdrare som kOrs av lastbilar till ndrmaste jarnvagsterminal. Ddr kan sedan lastbdrarna lastas am till tag. It is obvious to the person skilled in the art that by the load carrier Or load arranged on the chassis, the same can be moved between different roofs / transport types or the chassis with different track widths. The lift can e.g. garages with the aid of container trucks, terminal cranes or boundary trucks. This means that you can avoid a lot of transhipments of goods. Take as an example a company, mine or perhaps a forest that is being felled and which is located a short distance from a jdrnvdg. Dl can be loaded into load carriers that run by trucks to the nearest railway terminal. Ddr can then load the load carriers am to tag.

En fordel med att lastbdraren Or fOrsedd med bottenbalkarna 51 Or att de kan verka som stad, dl lastbdraren placeras marken eller nagot annat underlag. Detta mOjliggOr att den lasa lastbdrare, stdendes pd marken, kan farlastas, anvdndas som lager och vid tillfdlle lyftas upp pd ett fordon/tdg eller liknande far transport. Pd s& sdtt slipper man ha t.ex. ett 11 helt tag eller en lastbil vantandes under lastningen. Vid lossning kan man utnyttja fordelen av att kunna vaxla den lastade lastbararen mot en tom och pa sa satt halla fordonen sysseisatta mer effektivt. An advantage of the load carrier Or being provided with the bottom beams 51 Or that they can act as a city, where the load carrier is placed on the ground or some other surface. This makes it possible for the loaded load carrier, standing on the ground, to be unloaded, used as storage and, if necessary, lifted onto a vehicle / train or similar for transport. Pd s & sdtt you do not have to have e.g. an 11 full hold or a truck was missing during loading. When unloading, you can take advantage of being able to shift the loaded load carrier towards an empty one and in this way keep the vehicles employed more efficiently.

Ovan har beskrivits ett exempel pa en lastbarare far bulkgods men, sasom framgar av Fig. 13, är det mojligt att utnyttja olika typer av lastbarare avsedda for transport av t.ex. timmer 3b, vatska 3c mm. Det är aven mojligt att placera en ram 70 pa dragstangen/boggierna far majliggarande av transport av containrar 3a, varvid ramen har vasentligen samma storlek som containerns batten. Man kan pa sa satt enkelt omvandla sina vagnar efter det transportbehov man har vid varje tidpunkt genom att man har flera olika typer av lastbarare for varje underrede. I andra utforingsformer av transportanordningen kan aven t.ex. sjalva vagnsramen/dragstangen modifieras. Narmare bestamt kan den bytas ut far att anpassa langden och hallfastheten efter behov. Man kan ocksa ha en grupp av ramar avsedda for bottentommande lastbarare. Aven hjulen kan bytas ut mellan olika typer. I vissa fall vill man ha enkelaxliga vagnar 4c och andra ganger vagnar med boggi 4a,4b. Dessa i sin tur kan vara gjorda for olika axellaster. An example of a loader for bulk goods has been described above, but, as shown in Fig. 13, it is possible to use different types of loaders intended for transport of e.g. timber 3b, water 3c mm. It is also possible to place a frame 70 on the drawbar / bogies for transporting containers 3a, the frame being substantially the same size as the container's boat. You can thus easily convert your wagons according to the transport needs you have at any given time by having several different types of loaders for each chassis. In other embodiments of the transport device, e.g. the trolley frame / drawbar itself is modified. More specifically, it can be replaced by father to adjust the length and half-strength as needed. You can also have a group of frames intended for bottomless loaders. The wheels can also be replaced between different types. In some cases you want single-axle carriages 4c and other times carriages with bogies 4a, 4b. These in turn can be made for different axle loads.

Nar en typ av underrede godkants med en viss lastbarare, kravs endast relativt enkla simuleringar for att fa samma underrede godkant far en annan lastbarare. Da lastbararen är avsevart billigare an underredet, är det mojligt att relativt billigt ta tram nya lastbarare efter behov. When a type of chassis is approved with a certain loader, only relatively simple simulations are required to obtain the same chassis goodwill for another loader. As the load carrier is considerably cheaper than the chassis, it is possible to take new trams relatively cheaply as needed.

Av Fig. 13 framgar vidare att aven kopplen 2b,2c vid dragstangens andar kan bytas ut. Man kan byta mellan t.ex. vanliga standardkoppel 2c och centralkoppel 2b. Om man t.ex. oppnar en gruva och har sma transportbehov till att barja med, 12 kan man ha vagnar med vanliga koppel. DA kan man skicka sina vagnar i systemtag med vagnar fran olika vagnsOgare. N-Or kapacitetsbehovet Okar och man far ldngre och tyngre tag, kan man behova ga over till automatkoppel/centralkoppel 2b. Vidare kan dragstangens dndar forses, i fallet med standardkcppel 2c, med buffertar 2d. Fig. 13 further shows that also the couplings 2b, 2c at the spirals of the drawbar can be replaced. You can switch between e.g. standard standard leash 2c and central leash 2b. If one e.g. opens a mine and has small transport needs to start with, 12 you can have wagons with regular leashes. DA you can send your wagons in system tags with wagons from different wagon owners. N-Or the capacity requirement Increases and if you get longer and heavier, you may need to switch to automatic coupling / central coupling 2b. Furthermore, the ends of the drawbar can be provided, in the case of standard coupling 2c, with buffers 2d.

Det dr uppenbart far fackmannen att, i fall nationell lagstiftning eller andra regler sa kraver eller att behov fareligger, kan lastbdraren vara fast fOrbunden med vagnsunderredet/dragstangen. It is obvious to the person skilled in the art that, in case of national legislation or other rules such requirements or that the need is dangerous, the load carrier can be permanently connected to the trolley base / drawbar.

Av Fig. 1 och 2 framgar att systemet innefattar en transportanordning 1, i det visade fallet en jarnvagsvagn, innefattande en stomme eller ett vagnsunderrede i form av en langstrdckt stang 2 som är uppburen yid var dnde av en boggi 4a,4b. En lastbdrare 3 är lost uppburen pa stommen. It can be seen from Figs. 1 and 2 that the system comprises a transport device 1, in the case shown, a railway carriage, comprising a body or a carriage chassis in the form of an elongated rod 2 which is supported on each end of a bogie 4a, 4b. A load carrier 3 is loosely supported on the frame.

Lastbdraren Or utvdndigt yid en fOrsta sida 5a och en andra motstaende sida 5b forsedd med ingreppspunkter 6a,6b. Dessa ingreppspunkter Or identiska och symmetriskt placerade i farhallande till den fOrsta och den andra sidan 5a,5b av lastbdraren 3. Foretrddesvis är ingreppspunkterna placerade under nivan far lastbdrarens 3 botten. The load carrier Or externally yid a first side 5a and a second opposite side 5b provided with engagement points 6a, 6b. These points of engagement are identical and symmetrically located in relation to the first and second sides 5a, 5b of the load carrier 3. Preferably, the points of engagement are located below the level of the bottom of the load carrier 3.

Vidare innefattar systemet en fOrsta vdndanordning 10 inrdttad att dels komma till ingrepp med lastbdrarens ingreppspunkter 6a vid den fOrsta sidan 5a och dels att pAverka lastbdraren far vdndning av densamma genom att den fOrsta anordningen lyfter lastbdrarens fOrsta sida. Vid lyftningen av lastbdrarens 3 fOrsta sida 5a Or en andra vdndanordning 11 inrdttad att komma till ingrepp med lastbdrarens ingreppspunkter 6b vid den andra sidan 5b och att verka sasom lastbdrare for lastbdraren. Ndrmare bestdmt i en fOredragen utforingsform medfar lyftningen av den fOrsta sidan att 13 lastbdrarens andra sida "niger", varvid ingreppspunkterna 6b pa lastbararens andra sida forskjuts vertikalt nedat och kommer da till anliggning i lagerorgan 12 hos den andra vandanordningen 11, vilka lagerorgan 12 samverkar i detta lage med ingreppspunkterna 6b till bildande av en vridningsaxel A- A, sasom kommer att beskrivas narmare nedan under hanvisning till Fig. 6. Furthermore, the system comprises a first turning device 10 arranged to come into engagement with the load carrier's engaging points 6a at the first side 5a and partly to influence the load carrier to turn it by the first device lifting the front side of the load carrier. When lifting the first side 5a of the load carrier 3, a second turning device 11 is arranged to come into engagement with the points of engagement 6b of the load carrier at the second side 5b and to act as a load carrier for the load carrier. Further determined in a preferred embodiment, the lifting of the first side causes the second side of the load carrier to "niger", the engagement points 6b on the other side of the load carrier being displaced vertically downwards and then coming into abutment in bearing means 12 of the second water device 11, which bearing means 12 cooperate in this bearing with the engaging points 6b to form an axis of rotation A-A, as will be described in more detail below with reference to Fig. 6.

Genom att lastbararen är lost uppburen pa vagnsunderredet kan den pa ett enkelt sdtt flyttas/lyftas mellan olika vagnsunder- reden med t.ex. olika sparvidd, eller fran jdrnvdg till last- bil/semi-trailer/dumper eller vice versa. Because the load carrier is loosely supported on the trolley chassis, it can be moved / lifted in a simple way between different trolley chassis with e.g. different widths, or from jdrnvdg to truck / semi-trailer / dumper or vice versa.

I Fig. 1 visas schematiskt en lossningsstation vid vilken transportanordningen 1 är avsedd att vdndas. Lossningsstationen innefattar en schematiskt visad byggnad 20 som är fOrsedd med gejdrar 21 for styrning och farflyttning av den fOrsta vandanordningen 10. Vidare är en tOmningsficka 30 anordnad under och farskjuten i sidled i fOrhallande till transportanordningen 1. I tOmningsfickan 30 är ett flertal anslagsorgan 31 anordnade, mot vilka en byre kant 3a has lastbdraren 3 är avsedd att anligga i lastbararens fullstandigt vanda lage, se Fig. 5. Fig. 1 schematically shows a unloading station at which the transport device 1 is intended to be used. The unloading station comprises a schematically shown building 20 which is provided with guides 21 for guiding and moving the first water device 10. Furthermore, an emptying pocket 30 is arranged below and laterally displaced in relation to the transport device 1. In the emptying pocket 30 a plurality of abutment means 31 are arranged. against which a burr edge 3a has the load carrier 3 is intended to abut in the fully used layer of the load carrier, see Fig. 5.

Anslagsorganen kan eventuellt vara utformade fOr att ta upp staten, cid vandningen av lastbdraren stoppas, i stdllet for att denna belastning tas upp av lastbdraren och den forsta vdndanordningen. Detta leder till att man erhaller en stot som hjdlper till med tOmningen utan att man fOr den skull behover dimensionera upp lastbdraren och den farsta vandanordningen fOr denna extremlast, som kan uppsta da i vdrsta fall hela lasten sitter kvar i lastbdraren i detta ldge. Detta kan uppsta antingen genom att lasten är vdldigt kladdig eller att den har frusit fast. 14 I den visade utforingsformen innefattar den fOrsta vandanordningen 10 tva armar 10a, 10b varav en visas i Fig. 2. Den andra vandanordningen 11 innefattar pa motsvarande satt tva armar 11a,11b. De pi lastbirarens utsida anordnade ingrepps- punkterna 6a,6b ar i en fOredragen utfOringsform utformade pi samma satt och placerade i samma position pi lastbirarens bagge sidor. Detta medfor att lastbararens placering pa stommen blir riktningsoberoende. The stop means may optionally be designed to take up the state when the loading of the load carrier is stopped, instead of this load being taken up by the load carrier and the first turning device. This results in a bumper which assists with the emptying without the need to dimension the load carrier and the first water device for this extreme load, which can arise when in the worst case the entire load remains in the load carrier in this space. This can occur either because the load is very sticky or because it has frozen. In the embodiment shown, the first water device 10 comprises two arms 10a, 10b, one of which is shown in Fig. 2. The second water device 11 correspondingly comprises two arms 11a, 11b. The engaging points 6a, 6b arranged on the outside of the load carrier are in a preferred embodiment designed in the same way and placed in the same position on the rear sides of the load carrier. This means that the load carrier's location on the frame becomes direction-independent.

Det är uppenbart att den farsta och den andra vandanordningen kan innefatta fler an tva armar. Eventuellt kan den forsta vandanordningen innefatta endast en arm. It is obvious that the first and the second watering device can comprise more than two arms. Optionally, the first water device may comprise only one arm.

FOrdelarna med en eller flera armar hos den farsta vandanordningen är att axeln vid armens/armarnas kontakt med den halvcirkelformade gejdern/gejdrarna och axeln i armens/armarnas ingrepp i lastbararen gor att gejdern/gejdrarna inte behover vara exakt cirkelformad i forhallande till vridpunkten. Detta eftersom armen/armarnas vinkel kan tillatas att variera i farhallande till saval lastbarare som gejdern/gejdrarna. Avstandet till vridpunkten blir saledes inte lika kritiskt och man kan t.o.m. -Lanka sig en gejder/gejdrar med polygonform. The advantages of one or more arms of the first water device are that the shaft at the contact of the arm (s) with the semicircular guide (s) and the shaft of the engagement of the arm (s) in the load carrier means that the guide (s) need not be exactly circular in relation to the pivot point. This is because the angle (s) of the arm (s) can be allowed to vary in distance to saval loaders such as the guide (s). The distance to the pivot point is thus not as critical and you can even -Lank a guide / guides with polygon shape.

Detta medfar aven lagre krav pa precisionen hos tillverkningen av transportanordningen och positioneringen av densamma i lossningsstationen. This also entails lower requirements for the precision of the manufacture of the transport device and the positioning thereof in the unloading station.

Vidare innefattar lossningsstationen 20 icke visade organ for styrning och paverkan av den farsta 10 och den andra 11 vandanordningen, samt organ 60,61 for korrekt positionering av lastbararens 3 ingreppspunkter 6a,6b i forhAllande till den fOrsta och den andra vandanordningen, se Fig. 10-12. Narmare bestamt kan lossningsstationens 20 forst och andra vandanordning 10,11 vara inrattade att fOrskjutas synkront i vagnens langdriktning for att pi sa satt majliggora inriktning av den farsta och andra vandanordningen 10,11 i farhallande till ingreppspunkterna 6a,6b pa lastbararen. Detta med anledning av att det inte gar att positionera jarnvagsvagnar sarskilt noggrant med hjalp av loket i langdled, ca ±2 m. Furthermore, the unloading station 20 comprises means (not shown) for controlling and influencing the first 10 and the second 11 water device, as well as means 60,61 for correctly positioning the engaging points 6a, 6b of the load carrier 3 in relation to the first and the second water device, see Fig. 10 -12. More specifically, the first and second water devices 10, 11 of the unloading station 20 may be arranged to be displaced synchronously in the longitudinal direction of the carriage so as to allow alignment of the first and second water devices 10, 11 in relation to the engagement points 6a, 6b on the load carrier. This is due to the fact that it is not possible to position railway wagons particularly carefully with the help of the locomotive in the longitudinal direction, approx. ± 2 m.

Fig. 2-5 visar successiva sidovyer av vandningen av en lastbarare 3. Narmare bestamt visar Fig. 2 utgangslaget for vandning av lastbararen, varvid ingreppspunkterna 6a,6b hos lastbararen 3 har inriktats i forhallande till den forsta och den andra vandanordningen, och armarna till respektive vandningsanordning 10,11 befinner sig i ett inaktivt lage, startlage. I Fig. 3 har armarna till respektive vandningsanordning 10,11 rests upp till sitt aktiva lage, varvid ett griporgan/appen ogla 13, som är anordnat vid en forsta arida 14 av respektive arm 10a,10b, har forts till in- grepp med respektive ingreppspunkt 6a. Lagerorganen 12 has re- spektive armar 11a,11b har i detta lage inte kommit till ingrepp med respektive ingreppspunkt 6b. I Fig. 4 har en andra ande 15 av respektive arm 10a,10b forflyttats en stracka utmed gejdrarna 21. Denna farflyttning kan ske med hjalp av t.ex. joke visade wirar, kedjor, samverkande kugghjul/kuggstanger, eller nagra andra lampliga anordningar i kombination med brythjul dar sa behovs. Gejdrarna 21 är foretradesvis halvcirkelbagformade. Denna forflyttning av armarnas andra ande 15 medfor att de pa lastbararens motsatta sida anordnade ingreppspunkterna 6b kommer till ingrepp med lagerorganen 12 has armarna 11a,11b, varvid lagerorganen och ingreppspunkterna 6b bildar en vridningsaxel A-A kring vilken lastbararen kan vandas/tippas. I detta lage lyfts lastbararen fullstandigt fran stommen. I Fig. 5 visas ett lage i vilket lastbararen 3 har vants maximalt, och kanten 3a has lastbararen anligger mot anslagsorganen 31. Vidare framgar att vridningsaxeln A-A Or skild fran vagnsunderredet. 16 I en icke visad utforingsform dr den andra vdndanerdningen 11 inrdttad att forst komma till ingrepp med ingreppspunkterna 6b varefter den fOrsta vdndanordningen 10 dr inrdttad att komma till ingrepp med ingreppspunkterna 6a. Figs. 2-5 show successive side views of the irrigation of a load carrier 3. More specifically, Fig. 2 shows the starting layer for irrigation of the load carrier, wherein the engagement points 6a, 6b of the load carrier 3 have been aligned in relation to the first and the second watering device, and the arms of respective irrigation device 10,11 is in an inactive layer, starting layer. In Fig. 3, the arms of the respective irrigation device 10,11 have been raised to their active position, whereby a gripping member / app ogla 13, which is arranged at a first arid 14 of the respective arm 10a, 10b, has continued to engage with the respective intervention point 6a. The bearing members 12 have respective arms 11a, 11b have in this layer not come into engagement with the respective engagement point 6b. In Fig. 4, a second spirit 15 of the respective arm 10a, 10b has been moved a distance along the guides 21. This movement can take place with the aid of e.g. joke showed wires, chains, cooperating gears / racks, or some other suitable devices in combination with break wheels where needed. The guides 21 are preferably semicircular rear shaped. This movement of the second spirit 15 of the arms means that the engaging points 6b arranged on the opposite side of the load carrier come into engagement with the bearing means 12, the arms 11a, 11b, the bearing means and the engaging points 6b forming an axis of rotation A-A around which the load carrier can be watered / tipped. In this position, the load carrier is completely lifted from the frame. Fig. 5 shows a bearing in which the load carrier 3 has been used to the maximum, and the edge 3a has the load carrier abutting against the abutment means 31. It further appears that the axis of rotation A-A Or is separate from the carriage chassis. In an embodiment not shown, the second turning device 11 is arranged to first come into engagement with the engaging points 6b, after which the first turning device 10 is arranged to come into engagement with the engaging points 6a.

I ett icke visat ldge, ddr lastbdrarens batten är riktad ungefdr vertikalt och di lasten utgores av klibbande material, kan t.ex. en icke visad hjullastare hjdlpa till med att lossa lasten genom att skrapa ur densamma. Det dr dven mojligt att lossa lasten i detta ldge med hjdlp av spolning, en rensrobot eller for hand. In a layer (not shown), where the load of the load carrier is directed approximately vertically and the load is made of sticky material, e.g. a wheel loader (not shown) helps to loosen the load by scraping it out. It is also possible to unload the load at this level by means of flushing, a cleaning robot or by hand.

I Fig. 6 visas en forstorad partiell vy av ldget has armarna 11a,11b i Fig. 3. I detta ldge har armarna 11a,11b rests upp till sitt aktiva ldge med icke visade piverkningsorgan, i vilket ldge armarnas lagerorgan 12 är inriktade och anordnade att samverka med ingreppspunkterna 6b. Vid ingrepp mellan ingreppspunkterna och lagerorganen bildas en vridningsaxel AA, kring vilken lastbdraren kan vdndas/tippas, varvid armarna verkar sisom lastbarare fOr lastbararen di densamma vands. Fig. 6 shows an enlarged partial view of the lid having the arms 11a, 11b in Fig. 3. In this fold the arms 11a, 11b have been raised to their active length with pivoting means (not shown), in which the bearing members 12 of the arms are aligned and arranged to cooperate with the intervention points 6b. In engagement between the points of engagement and the bearing means, a rotation axis AA is formed, around which the load carrier can be turned / tipped, the arms acting as loaders for the load carrier in which it is turned.

Genom att placera vridningsaxeln skild frin vagnens stomme samtidigt som den verkar sasom lastbdrare for lastbdraren blir det majligt att vdnda/tippa lastbdraren mer eller mindre uppochner. Man fir ej heller nagot stabilitetsproblem has stommen/vagnsunderredet vid vdndning av lastbdraren. By placing the axis of rotation separate from the body of the trolley at the same time as it acts as a load carrier for the load carrier, it becomes possible to turn / tip the load carrier more or less upside down. There is also no stability problem with the frame / trolley chassis when turning the load carrier.

En ytterligare fordel med att placera vridningsaxeln skild Iran vagnens stomme är att vagnens totala vikt reduceras. An additional advantage of placing the pivot shaft separate from the Iran wagon body is that the wagon's total weight is reduced.

Enligt uppfinningen in det "lastbdrande gangjdrnet" integrerat i lossningsstationen och inte i vagnen, och ndrmare bestdmt i form av den andra vdndanordningen i kombination med ingreppspunkterna 6b. Vidare skall det "lastbdrande gingjdrnet" vara placerat i niva med eller under nivan for lastbdrarens batten. 17 Genom att placera ingreppspunkterna 6a,6b vid lastbdrarens underkant behover bara lastbdrarens bottenkonstruktion med ingreppspunkterna goras kraftig. Vidare utsdtts inte sjdlva iastbararen for nagra sidokrafter, varfor iastbararen inte behOver fOrstyvas och eventuell toppbalk och sidobalkar kan goras reiativt kiena. Detta medfor att iastbdraren kan goras lattare och darmed ta mer last. According to the invention, the "load-bearing hinge" is integrated in the unloading station and not in the trolley, and more specifically in the form of the second turning device in combination with the engaging points 6b. Furthermore, the "load-bearing swing" must be located at or below the level of the load carrier's bat. By placing the engagement points 6a, 6b at the lower edge of the load carrier, only the bottom construction of the load carrier with the engagement points needs to be made strong. Furthermore, the adjuster itself is not exposed to any lateral forces, so the adjuster does not need to be stiffened and any top beam and side beams can be made relatively smooth. This means that the load carrier can be made lighter and thus take more load.

Fig. 7 visar i sidovy overlagrade figurer av vandningssteg for en utfaringsform av lastbdraren 3 fOrsedd med ett appningsbart lock 40. Locket 40 är vid sina dndkanter forsett med lampliga organ 41, sasom tappar, som är inrdttade att komma till ingrepp med lampliga spar 42 for automatisk oppning av locket da lastbararen vands. Fig. 7 shows in side view superimposed figures of irrigation steps for an embodiment of the load carrier 3 provided with an openable lid 40. The lid 40 is provided at its ends with suitable means 41, such as pins, which are arranged to come into engagement with suitable grooves 42 for automatic opening of the lid when the load carrier is turned.

I Fig. 8 visas de cirkelbagformade gejdrarna 12' utforda av langre raka partier. Detta for att forenkla tillverkningen av desamma. Fig. 8 shows the circular bag-shaped guides 12 'challenged by longer straight portions. This is to simplify the manufacture of the same.

I Fig. 10 och 11 visas den forsta vandanordningen 11 i form av teleskoperande armar 10'. For att inrikta armarna 10' i vertikal led mot ingreppspunkterna är en styranordning 62 anordnad. Ndrmare bestdmt är ett mellan armarna 10' anordnat stag 63 inrdttat att styras av ett spar 64 i styrorganet tills armarnas 10' griporgan 13 är i kontakt med ingreppspunkterna. Figs. 10 and 11 show the first water device 11 in the form of telescopic arms 10 '. In order to align the arms 10 'in a vertical direction towards the points of engagement, a guide device 62 is provided. More specifically, a strut 63 arranged between the arms 10 'is arranged to be guided by a groove 64 in the guide means until the gripping means 13 of the arms 10' are in contact with the engaging points.

I en icke visad utforingsform kan gejdrarna vara utformade av tva raka partier som kan vara sammanbundna av en rundad Over- gang. Ndrmare bestdmt uppvisar respektive arm 10a, 10b en andra ande 15 inrdttad att utfora minst tva vdsentligen linjdra rarelser under vandningen av lastbdraren.
