Enligt uppfinningen kannetecknas lossningsapparaten i huvudsak av att stativet innefattar ett ramliknande underrede, bottenplattformen, forsett med minst en oppning genom vilken tilltrade till lastrummet mojliggores, och att en midskepps i langskeppsriktningen 15pande transportor, midskeppstransportoren, for upptagande av godset fran matningstratten stracker sig fran denna till stativets motsatta ande, dar en annan transportor, lossningstransportoren, som bildar en del av en svangbart lagrad utliggare eller lastbom är anordnad for lastens forslande Over fartygssidan. CLASS 65 a2: 32 INT. CLASS B 63 b PATENT PERIOD FROM SEPTEMBER 7, 1957 PROVIDED ON NOVEMBER 16, 1961 PUBLISHED ON APRIL 23, 1962 Aim 8152/1957, 7/9 1957, In addition to two drawings WG BARTENFELD, LAKEWOOD, OHIO, AMERICA UNITED STATES October 22, 1956 (United States) The present invention relates to unloading apparatus for cargo ships, including a gantry crane with a rack of such a width that it extends beyond the table edge of a cargo hold opening in the side of the ship, a device for moving the rack in the ship. longitudinal ship direction and one or more cargo buckets suspended in the frame, which are movable in the longitudinal direction of the ship, and a feed hopper device is arranged at one end of the frame for receiving goods from the cargo buckets. According to the invention, the unloading apparatus can be characterized mainly in that the frame comprises a frame-like chassis, the bottom platform, provided with at least one opening through which access to the cargo space is possible, and that a midships conveyor in the longitudinal direction 15 the opposite spirit of the stand, where another conveyor, the unloading conveyor, which forms part of a pivotally mounted outrigger or load boom, is arranged for the cargo to be transported across the ship's side.
Lossningsa:pparaten enligt foreliggande uppfinning innebar hi. a. den forbattringen att den liar forhallandevis liten konstruktionshiijd, varigenom den lampar sig sarskilt for insjofartyg, som Oro avsedda att lastas med pa kajen anordnade lastningsanordningar, som stracka sig in Over fartyget Mgt ovanfOr dettas dank. Da det galler oceangaende fartyg, vilka som regel Oro tamligen breda, Or problemet mindre, men pa insjofartyg kan overbyggnaden, da den Or hog i forhallande till fartygets bredd, omojliggora lastning av fartyget med maskinella lastningsanordningar av vissa typer, som numera aro i bruk i vissa hamnar, sarskilt i de stora kanadensiska sj arn a. The unloading apparatus of the present invention involved hi. a. the improvement that it has a relatively small construction height, whereby it lights up especially for inland vessels, which Oro intended to be loaded with loading devices arranged on the quay, which extend into the upper part of the vessel. As this applies to ocean-going vessels, which as a rule are rather wide, the problem is smaller, but on inland waterways the superstructure, as it is high in relation to the vessel's width, makes it impossible to load the vessel with mechanical loading devices of certain types, which are now in use in some ports, especially in the great Canadian lakes.

Till skillnad harifran Or lossningsapparaten enligt foreliggande ansokan lang, lag, stadig och stabil. Den 'Aga hajden astadkommes genom arivandande av den fribarande midskeppstransportoren, som stracker sig till lastapparatens fra.mre ande fran ett stalle n.ara dess motsatta Onde. Placeringen av matningstrattarna och lossningstransportoren mojliggor god fordelning av lasten pa vagnar. Lossningsapparatens laga hojd mojliggor ocksa att det kan anvandas i de fall da uthangande kajinstallationer finnas fOr lastning av stora lastfartyg sasom fallet Or i ett antal stader. Kanda unloading equipment As a rule, worry about sight Yoga, overweight and bring the ship to capsize when it comes out of a sheltered harbor. Unlike the other, the unloading device according to the present application is long, straight, stable and stable. The 'Aga shark is accomplished by the use of the free-carrying midship transporter, which extends to the front spirit of the loader from a stable near its opposite Evil. The location of the hopper and unloading conveyor enables good distribution of the load on wagons. The legal height of the unloading apparatus also makes it possible to use it in cases where overhanging quay installations are available for loading large cargo vessels, such as the case Or in a number of cities.
Utliggaren 6 Or svangbar c:a 180° i horisontalled, dvs. 900 at vardera sidan fran midskeppslaget, i vilket den visas i fig. 1, 2 och 3. Pa sh salt kan den anvandas for att lossa last med lika stor latthet Over den ena som den andra av fartygets bada sidor, dvs. babords- och styrbordssidan. Denna svangning av utliggaren astadkommes lampligen med hjalp a-v ett pa en lamplig centrumtapp lag-rat, stort kugghjul, som drives med hjalp av ett (joke visat) kuggdrev. Utliggaren kan dessutom svangas i vertikalled en vinkel av c:a 18° uppat Lan horisontalplanet, vilket under-'Attar lastens lossning i upplag pa en kajplan, vid vilken fartyget kan fortoj as. The outrigger 6 Or pivotable approx. 180 ° in the horizontal joint, ie. 900 at each side of the midships, in which it is shown in Figs. 1, 2 and 3. On sh salt it can be used to unload cargo with as much ease Over one as the other of the two sides of the ship, ie. port and starboard side. This oscillation of the cantilever is suitably effected by means of a large gear wheel mounted on a suitable center pin, which is driven by means of a gear shown (joke shown). The outrigger can also be pivoted vertically at an angle of about 18 ° up to the horizontal plane, which assumes the unloading of the load in support on a berth, at which the ship can be moored.
Sasom antydes i fig. 2, Or plattformen 7 forsedd med tva oppningar 11 och 12, genom vilka tilltrade erhalles till fartygets lastrum genom lastluckorna 3. Lfings fartygets midskeppslinje Oro oppningarna 11 och 12 skilda at genom ett smalt, bryggformigt parti 13, som forenar plattformens framre och bakre andpartier med varandra. I det bryggformiga partiet 13 Oro pa visat salt infasta tv parallella serier stolpar 14. Sasom framgar av fig. 3, ha dessa stolpar successivt 'Amide hojd 2— — raknat fran vanster till hoger mom serierna. Mellan stolparna 14 ãr anordnad en av dessa uppburen transportor 15, som under liten lutningsvinkel, hogst c:a 0, relativt horisontalplanet stracker sig fran plattformens 7 bakre till dess framre andparti. As indicated in Fig. 2, the platform 7 is provided with two openings 11 and 12, through which accesses are obtained to the ship's hold through the cargo hatches 3. Lfings of the ship's midship line The openings 11 and 12 are separated by a narrow, bridge-shaped portion 13, which unites the platform. anterior and posterior duck portions with each other. In the bridge-shaped portion 13 Oro on shown salt fasten two parallel series of posts 14. As can be seen from Fig. 3, these posts have successively 'amide height 2— - straightened from left to right of the series. Arranged between the posts 14 is one of these supported conveyors 15, which at a small angle of inclination, at most about 0, relative to the horizontal plane extends from the rear of the platform 7 to its front end portion.
Transportoren 15 at sa anordnad, att dess pamatningsande 16 befinner sig strax ovanfor platformens 7 plan. Dess utmatningsande 17 befinner sig mitt Over en matningstratt 18, som är belagen ovanfOr utliggarens 6 lure ande. Transportoren är utefter hela sin langd avskarmad medelst sidoplatar. Om sa Onskas, kan den vara helt innesluten i en trumma, men detta tr i regel icke nodvandigt. Da den at helagen mitt Over midskeppslinjen eller langskeppsaxeln mellan kranstativets sidor, benamnes denna transport& lampligen Ahngskeppstransportor». The conveyor 15 is arranged so that its feed end 16 is located just above the plane of the platform 7. Its discharge end 17 is located in the middle of a discharge funnel 18, which is located above the lure of the outrigger 6. The conveyor is shielded along its entire length by means of side plates. If said Onskas, it may be completely enclosed in a drum, but this is usually not necessary. Da den at helagen mitt Over midskeppslinjen eller langskeppsaxeln mellem kranstativets sides, benamnes detta transport & lampligen Ahngskeppstransportor ».
Pa plattformen 7 aro pa inbardes motsatta sidor om midskeppslinjen anordnade en motordriven forradstrumma 19 for den elkabel, som anvandes for tillforsel av elstrom till kranen, resp. en skrapmaskin 20 for renskrapning av lastrummet. Den forra ar plaeerad pa bakre och den senare pa framre andpartiet av plattformen 7. Fran trumman 19 matas kabeln 19a ned i en tragformig ranna 19b pa dacket 2. Med trumman samverka en kuggvaxel 19e, en motor 19d och en nedtransformator 19e for minskning av spanningen fran 2400 till 440 volt. Pa plattformen 7 vilar ovanfor transportoren 15 en forsta horisontell stativram 21, som tydligast visas I fig. 3 och 4. Denna rams lage i planvy i fOrhallande till plattformen antydes med prickstreckade linjer i fig. 2. Ramens 21 langskeppssidor bildas av ladbalkar 22. Dessa ladbalkar aro vid sina andar forenade genom 1-balker 23. Den salunda bildade ramen uppbares av sju pelare 24, vilkas lagen visas i fig. 2. Ett antal diagonalstravor 25, av vilka sex visas i fig. 2 (se aven fig. 4) anvandas for uppstravning och stabilisering av kranoverbyggnaden. Fran plattformen 7 uppskjuta fern I-balkar 26 pa visade stallen, och av dessa aro tva placerade pa vardera sidan om transportorens 15 langsmittlinje, strax utanfor transportoren. On the platform 7 aro on opposite sides of the midship line arranged a motor-driven storage drum 19 for the electric cable, which was used for supplying electric current to the crane, resp. a scraping machine 20 for scraping the cargo space. The former is placed on the rear and the latter on the front end portion of the platform 7. From the drum 19, the cable 19a is fed down into a trough-shaped gutter 19b on the roof 2. A gear shaft 19e, a motor 19d and a down-transformer 19e cooperate with the drum to reduce the voltage. from 2400 to 440 volts. On the platform 7 rests above the conveyor 15 a first horizontal frame frame 21, which is most clearly shown in Figs. 3 and 4. This frame's layer in plan view in relation to the platform is indicated by dotted lines in Fig. 2. The longitudinal sides of the frame 21 are formed by load beams 22. These loading beams are at their spirits united by 1-beams 23. The thus formed frame is supported by seven pillars 24, the layers of which are shown in Fig. 2. A number of diagonal beams 25, six of which are shown in Fig. 2 (see also Fig. 4) used for erection and stabilization of the crane superstructure. From the platform 7 project four I-beams 26 in the stables shown, and two of these are located on each side of the longitudinal center line of the conveyor 15, just outside the conveyor.
Tva av I-balkarna 26, vilka aro belagna vid bottenplattformens eller chassiets 7 framre andparti, bilda stod for en plattform 27 (fig. 3), som stracker sig tvarskepps mellan ladbalkarna 22. Akter om plattformen 27 och uppburen av stolpar 14 finnes en hytt 28 fOr en eller flera kranskotare, vilka kunna se ned i lastrummet genom Oppningarna 11 och 12 pa motsatta sidor om det bryggliknande mellanpartiet 13. Akter om hytten 28 finnes en matningstratt 29, som stracker sig tvarsOver kranstativet sasom visas i fig. 2. Denna tratt vilar pa fyra av de sju pelarna 24 och tre av de fern I-balkarna 26. Vid sin nedre an-de Sr tratten 29 forsedd med tva lamelltrans port&er 30 och 31, vilkas overparter forflytta sig i inbordes motsatta riktnmgar mot det centrala utmatningsomradet ovanfor en andra matningstratt 33 (fig. 3). Lamelltransportorerna 30 och 31 uppbaras av ett par sidoplatar 32, som aro synliga i fig. 3 och 4. Sa.- lunda kommer gods, som uppifran tommes i tratten 29, att av lamelltransportorerna 30 och 31 forslas till det gemensamma utmatningsomradet °Irani& tratten 33, genom vilken god-set matas ned pa langskeppstransportorens 15 pamatningsande 16. Two of the I-beams 26, which are located at the front end portion of the bottom platform or chassis 7, form a platform 27 (Fig. 3), which extends transversely between the loading beams 22. Aft of the platform 27 and supported by posts 14 is a cab 28 for one or more crane forwarders, which can look down into the cargo space through the openings 11 and 12 on opposite sides of the bridge-like intermediate portion 13. Aft of the cab 28 is a feed hopper 29, which extends across the crane frame as shown in Fig. 2. This hopper rests on four of the seven pillars 24 and three of the four I-beams 26. At its lower end, the funnel 29 is provided with two lamella transport ports 30 and 31, the upper parts of which move in opposite directions in the inner direction towards the central discharge area above a second hopper 33 (Fig. 3). The slat conveyors 30 and 31 are supported by a pair of side plates 32, which are visible in Figs. 3 and 4. Thus, goods which are emptied from above into the hopper 29 will be transported by the slat conveyors 30 and 31 to the common discharge area ° Irani & hopper 33. , through which the goods are fed down onto the feed end 16 of the longship conveyor 15.
Fran den horisontella ramen 21 uppskjuter vid kranens framre ande en A-formig stallning, soin bildas av tva snedstallda platbalkar 34, 35 och en tvarbalk 36 (fig. 4). Fran den A-formiga stallningens spets stracker sig bakat en strata 37, som loper diagonalt fran kranstativets framre till dess bakre ande. Vid kranstativets framre ande Sr stravan fast vid den A-formiga stallningen, medan den vid dess bakre ande ar fast vid I-balken 23, som pa detta stalle stodes av en av pelarna 24. Vid den A-formiga stallningens spets Sr fritt svangbart monterat ett taljeblock 38, genom vilket linor 39 aro dragna till utliggaren 6. From the horizontal frame 21 at the front end of the crane protrudes an A-shaped stand, which is formed by two inclined plate beams 34, 35 and a transverse beam 36 (Fig. 4). Extending from the tip of the A-shaped stand is a strata 37, which runs diagonally from the front of the crane frame to its rear spirit. At the front end of the crane frame Sr the strap is fixed to the A-shaped stand, while at its rear end it is fixed to the I-beam 23, which at this stand was supported by one of the pillars 24. At the tip of the A-shaped stand Sr is freely pivotally mounted a waist block 38, through which ropes 39 are drawn to the cantilever 6.
Ax fig. 3 °eh. 4 framgar vidare, att ovanfor den horisontella ramen 21 Sr anbragt en annan horisontell ram 43, som i langdled stracker sig ungefar lika langt at bada hallen som ramen 21 men Sr smalare an denna. Ramen 43 Midas delvis av tva I-balker 44, en vid vardera anden, av vilka balken vid den framre anden ing'ar i den. A-formiga stallningen. Mellan. dessa I-balkar lOpa tvit langsgaende bryggor 45 och 46, av vilka den fOrra bestar av tva pa stolpar 48 vilande I-balkar 47 och den senate bestar av tva. pastolpar 50 vilande I-balkar 49 (se fig. 4). Ramens 43 sidostycken bildas av bryggornas 45 och 46 yttre I-balkar. Stolparna 48 och 50 uppbaras av Ibalkarna 23 vid ramens 21 andar. Vid kranens framre ande bidrar A-stallningen, ()eh sarskilt platbalkarna 34 och 35, till att stodj a ramen 43, som Sr forstarkt genom horisontella I-balkar 51, som visas med streckade linjer i fig. 3. Ax Fig. 3 ° eh. 4 further shows that above the horizontal frame 21 Sr is arranged another horizontal frame 43, which in the longitudinal direction extends approximately as far to bathe the hall as the frame 21 but is narrower than this. Frame 43 Midas partly by two I-beams 44, one at each spirit, of which the beam at the front spirit is in it. The A-shaped stand. Between. these I-beams run two longitudinal bridges 45 and 46, of which the former consists of two on pillars 48 resting I-beams 47 and the senate consists of two. pastel pairs 50 resting I-beams 49 (see Fig. 4). The side pieces of the frame 43 are formed by the outer I-beams of the bridges 45 and 46. The posts 48 and 50 are supported by the Ibalkars 23 at the 21 spirits of the frame. At the front of the crane, the A-position, (especially the plate beams 34 and 35), helps to support the frame 43, which is reinforced by horizontal I-beams 51, which are shown in broken lines in Fig. 3.
Bryggan 45 uppbar ett skenpar Mr en akvagn 52. pa liknande satt uppbar bryggan 46 ett skenpar for en akvagn 53. Dessa akbanor Midas av raler eller skenor. Sasom framgar av fig. 4, lopa vagnarnas akbanor i langskeppsriktningen ovanfor oppningarna 11 och 12 i bottenplattformen 7. Stoppklackar 54 och 55 (fig. 3) begransa vagnarnas 52 ()eh 53 rorelsestracka. Vagnarna 52 och 53 drivas med hjalp av tva inbordes lika motor- och lintrumsaggregat 56, vilka axo monterade under vagnarna, pa ramens 21 plattform 27. Liner 57 aro dragna till vagnarna fran motor- och lintrumsaggregaten 56 (fig. 3). The jetty 45 carried a pair of rails Mr a water trolley 52. Similarly, the jetty 46 carried a pair of rails for a water trolley 53. These roller tracks are made of rails or rails. As can be seen from Fig. 4, the carriageways of the carriages run in the longitudinal direction above the openings 11 and 12 in the bottom platform 7. Stop lugs 54 and 55 (Fig. 3) delimit the movement track of the carriages 52 () and 53. The carriages 52 and 53 are driven by means of two inboard equal motor and lintel assemblies 56, which are axially mounted under the carriages, on the platform 27 of the frame 21. Lines 57 are drawn to the carriages from the motor and lintrum assemblies 56 (Fig. 3).
PS. bottenplattformens 7 bakre andparti aro monterade tva andra motor- och lintrums- — —3 aggregat 57 (fig. 3 och 4), frail vilka linor 59 aro dragna upp till hangbanevagnarna 52 och 53. Dessa linor, som lopa over i dessa vagnar anbragta linskivor, aro fasta vid under vagnarna 52 och 53 hangande lastskopor 62 och 63. Dessa lastskopor ha foretradesvis formen av gripskopor, upphangda i linorna 59 pa sadant satt, att deras vertikala delningsplan ligga i tvarskeppsriktningen. I detta fall stracker sig vardera skopans storsta dimension i skopans Oppna lage parallellt med fartygets langdaxel, och icke vinkelratt mot denna. Darvid komma saledes skopornas andar, men icke deras sidor, att vara vanda mot kranens framre resp. bakre ande (se fig. 3 och 4). PS. the rear end portion of the bottom platform 7 is mounted two other motor and cable compartment assemblies 57 (Figs. 3 and 4), from which ropes 59 are pulled up to the suspension carriages 52 and 53. These ropes, which run over in these carriages, are placed rope pulleys are attached to load buckets 62 and 63 hanging below the carriages 52 and 53. These load buckets preferably have the shape of grab buckets, suspended in the ropes 59 in such a way that their vertical dividing plane lies in the transverse ship direction. In this case, the largest dimension of each bucket extends in the open position of the bucket parallel to the longitudinal axis of the vessel, and not perpendicular to it. Thus the spirits of the buckets, but not their sides, become accustomed to the front resp. posterior spirit (see Figs. 3 and 4).
Da skoporna, da de aro upphangda pa detta sail, uppta relativt litet utrymme i tvarskeppsled, sasom visas i fig. 4, kan kranens Overrede, speciellt dess ovanfor den horisontella ramen 21 belagna del avsmalna uppat pa vi-sat satt, varigenom det blir mojligt att anvanda pa kajen anordnade matningsrannor for lastningsandamal. Trots att skopornas storsta dimension i oppet lage salunda ar parallell med fartygets langdaxel, foreligger ingen svarighet att fira ned skoporna i fartygets lastrum genom oppningarna 11 och 12 i bottenplattformen 7. I fig. 3 visas den ena skopan 63 med streckade linjer i nedfirat lage. Fran detta lage hissas den upp av kranskotaren med hjalp av linorna 59, varefter den forflyttas i fartygets langdriktning ph den bana, som ingar i bryggan 46, tills den anlander mitt Over tratten 29, van i skopan diireftcr kan tommas. Skopan 62, som i fig. 3 visas i tomningslage, manovreras ph liknande salt, oberoende av skopan 63. Since the buckets, as they are suspended on this sail, take up relatively little space in the transverse joint, as shown in Fig. 4, the upper part of the crane, especially its part located above the horizontal frame 21, can taper upwards in the manner shown, whereby it becomes possible to use feed chutes arranged on the quay for loading purposes. Although the largest dimension of the buckets in the upright position is parallel to the longitudinal axis of the vessel, there is no responsibility to lower the buckets into the vessel's cargo space through the openings 11 and 12 in the bottom platform 7. Fig. 3 shows one bucket 63 with dashed lines in lowered bearing. From this position it is hoisted up by the forwarder with the aid of the ropes 59, after which it is moved in the longitudinal direction of the ship along the path which enters the pier 46, until it arrives in the middle of the funnel 29, used in the bucket diireftcr can be emptied. The bucket 62, which is shown in Fig. 3 in emptying mode, is maneuvered ph similar to salt, independently of the bucket 63.
Genom den beskrivna anordningen minskas lossningsapparatens totala hojd och dess tyngdpunkt forflyttas foljaktligen nedat. Matningstrattarna 29 och 33, lamelltransportorerna 30 och 31 samt motor- och lintrumsaggregaten 58 utbalansera utliggarens 6 vikt, sa att god belastningsfordelning erhalles. Da samtliga dessa anordningar aro monterade pa bottenplattformen 7, underlattas deras Oversyn och reparation, och det blir mojligt att anvanda maskiner och andra anordningar med stor kapacitet. Samtidigt mojliggor den relativt ringa lutningsvinkeln hos den centrala langskeppstransportoren 15 att man kan hantera mass- eller smastyckigt gods, sasom t. ex. krossad jarnmalm, som icke garna kan transporteras under storre vinklar an 15°. Da fartyget befinner sig till sj5ss, kunna lastskoporna vara stuvade i lastrummet, sa att man far fri sikt akteri3ver fran styrhytten 65 genom kranen 5, ovanfor den horisontella ramen 21. As a result of the described device, the total height of the unloading apparatus is reduced and its center of gravity is consequently moved downwards. The feed hoppers 29 and 33, the lamella conveyors 30 and 31 and the motor and lintel units 58 balance the weight of the cantilever 6, so that a good load distribution is obtained. Since all these devices are mounted on the bottom platform 7, their inspection and repair is facilitated, and it becomes possible to use machines and other devices with large capacity. At the same time, the relatively small angle of inclination of the central longship conveyor 15 makes it possible to handle bulk or small cargo goods, such as e.g. crushed iron ore, which can not be transported at greater angles than 15 °. When the ship is at sea, the cargo buckets can be stowed in the cargo hold, so that there is a clear view aft from the wheelhouse 65 through the crane 5, above the horizontal frame 21.
Da bottenplattformen 7 befinner sig ett gott stycke ovanfor fartygets shelterdack, är det mojligt att utnyttja kranen for att avtaga och palagga lastrumsluckorna. For detta an damal dragas linor fran hangbanevagnarna 52 och 53 till den lastrumslucka, som skall forflyttas, varefter denna lucka kan lyftas fran den plats dar den f5r tillfallet befinner sig och transporteras till ett annat stalle ph fartygets dack. Om flera lastrumsluckor skola avtagas, kunna dessa utan svarighet staplas pa varandra pa en f5rvaringsplats. Da fartyget skall lossas, forflyttas kranen darefter till den. lastlucksoppning, dar lossning skall borja, varefter skoporna 62 och 63 sattas i arbete pa redan beskrivet satt. Sedan lossningen av fartyget avslutats, kan. kranen Ater anvandas for palaggning av lastrumsluckorna pa sin plats over luclappningarna. As the bottom platform 7 is located a good distance above the ship's shelter deck, it is possible to use the crane to remove and repair the cargo hold hatches. For this purpose, ropes are drawn from the trolleys 52 and 53 to the cargo hold hatch to be moved, after which this hatch can be lifted from the place where it is before the incident and transported to another stall on the ship's deck. If several cargo compartment doors are to be removed, these can be stacked on top of each other in a storage place without liability. When the ship is to be unloaded, the crane is then moved to it. cargo hatch opening, where unloading is to begin, after which the buckets 62 and 63 are put into operation in the manner already described. After the unloading of the vessel is completed, can. the Ater crane is used to install the cargo hatch doors in place over the hatch flaps.
Uppfinningen kan i princip och med de fiesta av de beskrivna fordelarna tillampas aven pa ett oceangaende fartyg 71 av den typ som visas i fig. 5. I vanliga fall har ett dylikt fartyg tva parallella serier lastluckor. 72 och 73, den ena pa babords- och den andra pa styrbordssidan om midskeppslinjen. Ett underrede eller chassi 74 air plattformstyp, vilket fir bredare au men eljest i princip av samma utforande som plattformen 7 i fOregdende utforingsform av uppfinningen, stracker sig tvarskepps Over bada lastlucksserierna. Bet uppbares av Akvagnar, som 15pa pa raler eller skenor bordvarts om luckoppningarna. The invention can in principle and with most of the described advantages also be applied to an ocean-going vessel 71 of the type shown in Fig. 5. In ordinary cases such a vessel has two parallel series of cargo hatches. 72 and 73, one on the port side and the other on the starboard side of the midship line. A chassis or chassis 74 air platform type, which has a wider au but otherwise in principle of the same design as the platform 7 in the previous embodiment of the invention, extends transversely across the cargo hatch series. Beets are carried by water carts, which are 15 pallets or rails across the table around the hatch openings.
Pa underredet eller bottenplattformen 74 aro pelare 75 och snedstravor 76 beldgna utanfor den centrala langskeppstransportoren 77, den framre matningstratten 78 och tva bakre matningstrattar 79 och 80. Marna 7uppbarn en fOrsta horisontell rain 81, pa vilken fir monterad en A-formig stallning, bestaende av de hada lutande platbalkarna 82 och 83 samt ett toppbeslag 84. Fran det sistnamnda stracker sig en snedstrava 85 bakat pa ungefar samma salt som stravan 37 i den redan beskrivna utforingsformen av uppfinningen. Ovanfor den fOrsta horisontella ramen 81 befinner sig en andra horisontell ram 86, som uppbar ett par bryggor 87 och 88, pa vilka hangbanevagnar 89 resp. 90 aro akbara. Vagnen 89, uppbar en lastskopa 91 och vagnen 90 en lastskopa 92. On the chassis or bottom platform 74, pillars 75 and oblique struts 76 are located outside the central longship conveyor 77, the front feed hopper 78 and two rear feed hoops 79 and 80. Marna 7 supports a first horizontal rain 81, on which is mounted an A-shaped stand, consisting of they had sloping plate beams 82 and 83 and a top fitting 84. From the latter extends an oblique strut 85 baked on approximately the same salt as the strut 37 in the already described embodiment of the invention. Above the first horizontal frame 81 is a second horizontal frame 86, which supported a pair of bridges 87 and 88, on which suspension carriages 89 and 89, respectively. 90 aro akbara. The trolley 89 carried a loading bucket 91 and the trolley 90 a loading bucket 92.
Da fartygets bredd ar relativt stor, finnes ingen sarskild anledning att hanga upp skoporna 91 och 92 pa sadant satt, att deras stOrsta dimension i 5ppet lage stracker sig parallellt med fartygets langdaxel. I stallet kunna de, sasom visas i fig. 5, hangas upp i sadant Ihge, att deras vertikala delningsplan rigger I ett med denna axel parallellt plan. Skoporna ttimmas i var sin av de hada matningstrattarna vid kranens bakre ande, skopan 91 i tratten. 79 och skopan 92 i tratten 80. Godset forslas f5rover av den centrala 0 midskeppstransportoren 77 och utmatas av denna i den. framre matningstratten 78 ovanf or utliggartransportorens 6 inre lade. As the width of the vessel is relatively large, there is no particular reason to hang the buckets 91 and 92 in such a way that their largest dimension in the open space extends parallel to the long axis of the vessel. Instead, as shown in Fig. 5, they can be suspended in such a way that their vertical dividing plane rigs in a plane parallel to this axis. The buckets are timed in each of the hot hobs at the rear end of the tap, bucket 91 in the hopper. 79 and the bucket 92 in the hopper 80. The goods are transported forward by the central midship transporter 77 and discharged therefrom. the front hopper 78 above the inner bed of the cantilever conveyor 6.
Betraffande saval insjofartyget enligt fig. — — 1-4 som det oceangaende fartyget enligt fig. ãr att marka, att lossningsapparaten enligt foreliggande uppfinning är val lampad for anvandning ombord pa s. k. kombinationslastfartyg, dvs. fartyg som aro avsedda att kunna fora saval oIje- och andra flytande laster i >>btilk> som vissa vanliga terra massgods'aster, t. ex. kombinerade tank- och malmfartyg. Ingen komplicerad maskinell utrustning i form av matningstrattar, skopelevatorer osv. behbver installeras i lastrummen och minska dessas nyttiga lastutrymme samt onodigtvis Oka fartygets deplaeement. I dessa avseenden erbjuder ett fartyg, utrustat med lossningsapparaten enligt foreliggande uppfinning betydande f5rdelar aven gentemot den sedvanliga typen av sjalvlossande fartyg. En av dessa f8rdelar ligger i att en storre mangd nyttig last kan foras av ett fartyg av given storlek och med samma djupgaende. Regarding both the seagoing vessel according to Figs. 1-4 as the ocean-going vessel according to Fig., It should be noted that the unloading apparatus according to the present invention is selected for use on board so-called combination cargo vessels, ie. vessels which are intended to be able to carry salvage oil and other floating cargoes in >> btilk> as certain ordinary terra mass goods' aaster, e.g. combined tankers and ore vessels. No complicated mechanical equipment in the form of hobs, bucket elevators, etc. need to be installed in the cargo holds and reduce their useful cargo space as well as unnecessarily increase the ship's deplaeement. In these respects, a vessel equipped with the unloading apparatus according to the present invention also offers significant advantages over the usual type of self-unloading vessel. One of these advantages lies in the fact that a larger amount of useful cargo can be carried by a ship of a given size and with the same draft.
Da en lossningsapparat enligt foreliggande uppfinning an.vandes, blir anskaffningskostnaden for lossningsutrustningen vida lagre an for den lossningsutrustning, som behovs vid ett sjalvlossande fartyg av sedvanlig typ. Fartyg, utrustade med en lossningsapparat enligt foreliggande uppfinning, kunna lastas och vid behov aven lossas med hjalp av vanlig kajbaserad utrustning for lossning och lastning. I de fiesta fall kan den i fig. 1 visade kranen, om sa onskas, fiven anvandas i andvant lage relativt det visade, varvid dess surrningsstativ 9 i stallet skall anordnas omedelhart akter om f6rliga dackshuset 65. I detta fall stracter sig utliggaren 6 i insvangt lage givetvis akterover i stallet for forover, sa.- som visas i fig. 1-3. When an unloading apparatus according to the present invention is used, the acquisition cost of the unloading equipment is far lower than the unloading equipment needed in a self-unloading vessel of the usual type. Vessels, equipped with an unloading apparatus according to the present invention, can be loaded and, if necessary, also unloaded with the aid of ordinary quay-based equipment for unloading and loading. In most cases, the crane shown in Fig. 1 can, if desired, be used in the usual position relative to that shown, its lashing frame 9 being arranged in the stern immediately aft of the former dacks housing 65. In this case the outrigger 6 extends inwardly. make, of course, aft in the stable for forward, as shown in Figs. 1-3.
Del inses utan vidare av fackmannen, att 5.ven andra modifikationer av de beskrivna utforingsformerna kunna gams utan avsteg fran uppfinningstanken. Det är salunda tydligt, att lossningsapparaten Aven, om sâ onskas, kan inga som en del av en kajbaserad utrustning, genom att den placeras pa rater eller skenor, som lopa tangs en slip eller tva parallella kajer vid en stapelplats eller en serie massgodsupplag, dar en pram, laktare e. d. kan tas emot. I detta fall kommer lossningsapparaten givetvis att stracka sig Over och utanfor fartygets lastrum och sidor. Under sadana forhallanden kan antingen loss- ningsapparaten eller fartyget, eller badadera, forflyttas tangs stapelplatsen (eventuellt en slip) eller grupperna av upplag i omedelbart samband med att lastrummet lossas. liven andra variationer kunna ske utan avsteg fran uppfinningstanken. e.It will be readily apparent to those skilled in the art that other modifications of the described embodiments may be made without departing from the spirit of the invention. It is thus clear that the unloading apparatus Aven, if desired, can not be used as part of a quay-based equipment, by placing it on rails or rails, which run along a slip or two parallel quays at a stacking site or a series of bulk warehouses. a barge, lactare oath can be received. In this case, the unloader will of course extend over and outside the ship's hold and sides. Under such conditions, either the unloading device or the vessel, or the bathing vessel, can be moved to the tang stack (possibly a slip) or the groups of warehouses in immediate connection with the unloading of the hold. other variations can take place without deviating from the inventive concept. e.
