Uppfinnare: NV Svensson och B N A Svenson Uppfinningen avser ett monteringsplan storre byggnadskonstruktioner, sasom fartyg eller delar darav. Pa grund. av den stora tyngden has dylika konstruktioner miste badden och slladarna, pa vilka monteringen skall ske, vara oerhort kraftiga och for konstruktionens farflyttning liar man kven mast tillgripa olika algarder far minskning av friktionen mellan badden och sladarna. Den hit-tills vanliga utformningen bestar darfor av sladar, 'som med en stor, plan baryta vilar direkt pi& sladbanan, oth for att minska friktionen forses banorna med ett lager fett e. d. Emellertid är vilofriktionen has en sadan badd-konstruktion avsevart storre an. glidfriktionen, varfor iganigsattning av rarelsen fordrar star kraft, medan dess stoppande icke kan beraknas ske med nagon stone precision. Inventors: NV Svensson and B N A Svenson The invention relates to an assembly plan for larger building structures, such as ships or parts thereof. Basically. Due to the large weight, such constructions lose the baths and sleds, on which the assembly is to take place, are extremely strong, and for the movement of the construction one has to resort to different algae to reduce the friction between the baths and the sleds. The hitherto standard design therefore consists of cables, which with a large, flat surface rest directly on the cableway, and in order to reduce the friction the tracks are provided with a layer of grease, etc. However, the rest friction has such a bath construction considerably larger. the sliding friction, for which the initiation of the movement requires rigid force, while its stopping cannot be calculated to take place with any stone precision.

Denna monteringsbana är darfOr olamplig if all det galler att suceessivt fOrflytta och stoppa de uppbyggda konstruktionerna, och uppfinningens andamit är att undanrOja de med dylika sladbanor forbundna olagenheterna. This mounting path is therefore unsuitable in all cases of successively moving and stopping the built-up structures, and the spirit of the invention is to eliminate the malfunctions associated with such cable paths.

Foreliggande uppfinning hanfor sig till ett monteringsplan av det slag som angives i ingressen till patentanspraket 1 och ovannamnda olagenheter avhjalpas genom att monteringsplanet enligt uppfinningen erhallit de i patentanspraket 1 angivna kannetecknen. The present invention relates to a mounting plane of the type stated in the preamble of patent claim 1 and the above-mentioned malfunctions are remedied by the mounting plane according to the invention receiving the pitcher marks specified in patent claim 1.

Uppfinningens tillampning vid en fartygsbadd askadliggores pa bifogade ritningar, i vilka fig. 1 visar en tviarsektion genom bad-den, fig. 2 visar en perspektivisk vy av en rullsats, fig. 3 visar rullsatsen i fig. 2 avanifran, fig. 4 visar en detalj av ett vertikalstod for blocken, fig. 5 Visa" en schematisk sidovy av badden och fig. 6 visar en sidovy av ett block, uppstallt pa ett antal rullsatser. The application of the invention to a ship bath is illustrated in the accompanying drawings, in which Fig. 1 shows a cross section through the baths, Fig. 2 shows a perspective view of a roller set, Fig. 3 shows the roll set in Fig. 2 from above, Fig. 4 shows a detail of a vertical pillar for the blocks, Fig. 5 shows a schematic side view of the bath and Fig. 6 shows a side view of a block, arranged on a number of roller sets.

De beskrivna monteringsbanorna aro byggda i en s. k.ba.dd'ocka och har ett kraftigt fundament 1, lampligen av betong med uppgjutna aral1elia strangar 2, i vilka stalbalkar 3 aro ingjutnk„ och villa pa ovansidan bilda ei slat rullbana 4. Fig. 1 visar tre dylika strangar men antalet kan givetvis vaxla alltefter fordringarrra, sa att aven tva eller flera strangar kunna forekomma. Rullbanorna 4 aro horisontella eller svagt lutande och uppbara rullsatser 5, lampligen utefter hela sin langd. P rnllsatserna 6 arc block 6 av tra e. d. placerade, vilkas undersida Or skodd med en ladformad stalbalk 7, som bildar en undre plan yta for anliggning mot rullarna 8 i rull7 satserna. Ovanpa blocken 6 uppmonteras byggnadskonstruktionen 9, eventuelit pa en mellanliggande arbetsplattform eller dylikt, Aiken i sidled stracker sig Over alla blocken 6 pa de olika strangarna. The described mounting tracks are built in a scaffold and have a strong foundation 1, preferably of concrete with cast-in-place allelic strands 2, in which steel beams 3 are cast in and the villa at the top forms a smooth roller track 4. Fig. 1 shows three such strings, but the number can of course vary according to the requirements, so that even two or more strings can occur. The roller tracks 4 are horizontal or slightly inclined and support roller sets 5, suitably along their entire length. P rnllsats 6 arc blocks 6 of tra e. D. Placed, whose underside Or is shuttered with a load-shaped steel beam 7, which forms a lower flat surface for abutment against the rollers 8 in the roll7 sets. Above the blocks 6, the building structure 9 is mounted, possibly on an intermediate work platform or the like. The axis extends laterally over all the blocks 6 on the various strands.

Rullsatserna 5 bestk av ett antal roterbara rullar 8, styrda av genomgaende axlar 10, viika aro fast inspanda i sidostycken 11. Rullarna 8 aro forsedda med en radiell urtagning 12, vilken samverkar med en pa rullbanan 4 anordnad langsgaende skena 13, vilken styr rullarna 8 i banornas tvarriktning. Rullsatsens bada andruflar aro kortare an de &riga. Vid ena rullens andar aro bakar 14 eller dylikt svangbart lagrade pa axeln 11. Vid andra rullens andar aro, distanshylsor 15 insatta pa axeln 11. Franakanten pa hakarna 11 Or snett avfasad, sa att ndr en rullsats skjutes mot intilliggande rullsats lyiftes hakarna 14 pi ena rullsatsen Over distanshylsorma 15 pa andra rullsatsen och gripa tag om dessa, varigenom rullsatserna automatiskt hopkopplas till en enhet. I stallet for hakarna 14 kunna givetvis andra hopkopplingsanordningar Threkomma. The roller sets 5 consist of a number of rotatable rollers 8, guided by continuous shafts 10, which are fixedly clamped in the side pieces 11. The rollers 8 are provided with a radial recess 12, which cooperates with a longitudinal rail 13 arranged on the roller track 4, which guides the rollers 8 in the transverse direction of the tracks. Both of the roller sets are shorter than the ones. At the ends of one roller are 14 or similarly pivotally mounted on the shaft 11. At the ends of the other roller are spacers 15 inserted on the shaft 11. The front edge of the hooks 11 is bevelled so that when a roller set is pushed against the adjacent roller set the hooks 14 are lifted on one the roller set Over the spacer sleeves 15 on the second roller set and grip these, whereby the roller sets are automatically connected to one unit. Instead of the hooks 14, of course, other connecting devices can Threkomma.

Pa undersidan av halken 7 pa blocket 6 är likaledes en skena 16 anbragt, vilkeni aven samverkar med urtagningen 12 i rullarna 8 for att styra blacken i sidled. tMellan. ,strangarna 2 Or lkmpligen en. nedsankt rullbana 17 anordnad, vilken a" forsedd med en styrlist 18 och derma rullhana 2— — Si avsedd for fOrflyttning av rullsatser och block fran baddens bortre ande till dess borjan, allteftersom de i samband med byggnadskonstruktionens 'forskjutning frigoras. On the underside of the slide 7 on the block 6, a rail 16 is likewise arranged, which also cooperates with the recess 12 in the rollers 8 to guide the black sideways. tMellan. , strangarna 2 Or lkmpligen en. a submerged roller conveyor 17 is provided, which is provided with a guide strip 18 and its roller cock 2 - - Si intended for moving roller sets and blocks from the far end of the bath to its beginning, as they are released in connection with the displacement of the building structure.

Montering av en byggnadskonstruktion foljande satt. badden är frail borjan rullsatserna 5 uppstallda, lampligen utefter baddens hela langd, och vid ena anden ,placeras sá manga block 6, som ungefar motsvara langden av den konstruktionsenhet 9, som skall uppstal- las, i det visade fallet tva: block pa. varje bana. Assembly of a building structure following set. The baths are arranged at the beginning of the roller sets 5, suitably along the entire length of the bath, and at one end, so many blocks 6 are placed, which approximately correspond to the length of the construction unit 9 to be erected, in the case shown two: blocks pa. each lane.

Sedan denna enhet fardigmonterats, forskjutes densamma medelst en limplig anordning, t. ex. ett antal hydrauliska domkrafter 19, som pressas mot andarna av blocken 6 en. stracka, som motsvarar en blocklangd, var- efter ytterligare rullsatseroch ett block 6 placeras pa vardera banan 4 mellan den tillbakadragna donakraften och den fardignionterade delen. Darefter flyttas enheten anyo en distans motsvarande en blocklangd. After this unit has been assembled, it is displaced by means of an adhesive device, e.g. a number of hydraulic jacks 19, which are pressed against the spirits of the blocks 6 a. distance, which corresponds to a block length, after which additional roller sets and a block 6 are placed on each path 4 between the retracted donor force and the vehicle-oriented part. Then the unit is moved anyo a distance corresponding to a block length.

Under blockens forflyttning kommer rullsatserna 5 att rdra sig framat halften sa lang stracka sorn blocken, vilket Sr formanligt ur transportsynpunkt. Nya rullsatser och block placeras p5. rullbanorna, och dessa to.gas fran banana 4 bortre ande, dar de lyftes ned pa de "nedsankta banorna 17 oth transporteras under monteringsenheten 9 -LEH framre anden. Vid de tillfallen da. en sektions langd motsvaras av flera block och ãr sttirre an. dom- kraftens slag, maste man vidtaga atgarder for att under den senare delen ray fOrskjutrningen fOrhindra att de nypalagda Linn obe- lastade blocken lyftas frau rullsatserna. Detta forhindras medelst istodorgan 29, sum aro svangbart monterade p5. fundamentet 1 och .besta. av en vid ena anden lagrad arm, som -yid andra Emden Ex forsedd med en roterbar rulle 21, vilken samverkar med en rullbana, anordnad pa balken 7 pa. blocket 6. Darige- nom Mlles blocket nedpressat mot rullsatserna 5, sä att blocken icke kunna vikas upp mot varandra. Da byggnodskonstruktionen vilar pa blocken, erfordras icke nagot dylikt stod, utan detta kan svangas ned sasom visas i fig. 5. Pa badden kan successivt de olika monte- ringsenheterna 9 sammanbyggas, och forflyttfling sker sS snart en enhet är klar. Monte- ringsarbetet kani dadar ske p5. samma plats utefter badden, vilket underlattar .arbetet och mdjliggor att arbetet kan utforas under tak, i det att en hall kan byggas over baddens ena ande. Eftersom bidden är plan eller svagt lu-tande och rullningsfriktionen relativt lag, erfordras icke alltfor stor kraft for byggnads- konstruktionens forflyttning, och den kan Mott stoppas p5. avsett stalle. During the movement of the blocks, the roller sets 5 will move forward half as long as the blocks, which is advisable from a transport point of view. New roller sets and blocks are placed on p5. the roller tracks, and these are gased from the far end of the track 4, where they are lifted down on the "submerged tracks 17" and transported under the mounting unit 9 -LEH front end. In those cases when a section length corresponds to several blocks and is larger. the stroke of the jack, measures must be taken to prevent the newly laid Linn unloaded blocks from being lifted from the rollers during the latter part of the displacement. This is prevented by means of piston means 29, which are pivotally mounted on the foundation 1 and consisting of a at one second stored arm, as -yid other Emden Ex provided with a rotatable roller 21, which cooperates with a roller conveyor, arranged on the beam 7 on the block 6. Thereby Mlles the block is pressed down against the roller sets 5, so that the blocks can not be folded As the building construction rests on the blocks, no such stand is required, but this can be swung down as shown in Fig. 5. On the baths the various mounting units 9 can be successively assembled, and so on. surface flattening occurs sS as soon as a unit is ready. The assembly work can be done p5. the same place along the bath, which facilitates the work and makes it possible for the work to be carried out under a roof, in that a hall can be built over one spirit of the bath. Since the bit is flat or slightly sloping and the rolling friction is relatively low, not too much force is required for the movement of the building structure, and it can be stopped. set aside stables.

Blocken 6 aro pa ovansidan forsedda med ett antal urtagningar 22, vilka stracka sig .tvarsover blocken och ha en langd i blockens langdriktning, som overstiger avstandet me1- 1.an tva urtagningar. Denim anordning liar till andamdl att mojliggora exempelvis mSlning ,av hela konstruktionens undersida, vilken fran bbrjan kan fardigmalas sâ nar som pa de partier, som vila p5. blocken. Darefter fylles dockan med vatten, sa. att fartyget Uttar Iran blocken och det kan darefter halas lang stracka, att de partier„ som fOrut vilat pa blocken, komma att befinna sig mittfor urtagningarna 22. Efter urtappning av vattnet ur dockan kan saledes de nu frilagda partierna fardigmalas. The blocks 6 are provided at the top with a number of recesses 22, which extend across the blocks and have a length in the longitudinal direction of the blocks, which exceeds the distance between two recesses. The denim device is intended to enable, for example, painting of the underside of the entire structure, which from the outset can be painted as well as on the parts resting on it. blocks. Then the doll is filled with water, he said. that the ship removes the Iran blocks and it can then be hauled for a long distance, that the parts "which previously rested on the blocks, will be located in front of the recesses 22. After draining the water from the dock, the now exposed parts can thus be painted.

Den beskrivna anordningen kan modifieras inom uppfinningens ram. Salunda kan t. ex. en del av rullarna 8 vara forbundna med separata drivorgan och/eller bromsanordningar. Monteringsplanet har beskrivits i sarnband med en fartygsbadd, men det Sr givetvis lika anvandbart vid montering av viktigare delar av fartyget eller liknande stora enheter inom andra tillverkningsomraden, dar forfl3rttningar maste forekonrara. The described device can be modified within the scope of the invention. Salunda can e.g. some of the rollers 8 be connected to separate drive means and / or braking devices. The assembly plane has been described in conjunction with a ship's hull, but it is of course equally useful when assembling more important parts of the ship or similar large units in other manufacturing areas, where movements must occur.
