In Fig. 5, finally, is a top view of a cassette for a carriage according to Figs. 1-3.
Vid gjutning av konsekutiva betongelement i en lång formbädd bestående av ett antal intilliggande, vertikalt rör- liga formar utföres successiv avformning med hjälp av en sär- skild på sagda räler rörlig avformningsvagn (icke visad).When casting consecutive concrete elements in a long mold bed consisting of a number of adjacent, vertically movable molds, successive molding is carried out by means of a special molding trolley (not shown) on said rails.
Efter avformningen kan formen rengöras från betongrester med utnyttjande av en särskild rengöringsvagn (icke visad) för- sedd med vertikalt rörliga, mot formens insider ingripande skraporgan (icke visade) och i formen införda blåsmunstycken för avgivning av en luftstråle av högt tryck (icke visade).After demolding, the mold can be cleaned of concrete residues using a special cleaning trolley (not shown) equipped with vertically movable scraper means (not shown) engaging the inside of the mold and blowing nozzles inserted into the mold to deliver a high pressure air jet (not shown) .
Efter det att formen iordninggjorts för gjutning skall - innan gjutoperationen påbörjas - i formen appliceras rälsmellanlägg av gummi av det slag som beskrives i.den svenska patentskriften.73 06727-4. Därvid utnyttjas en vagn. av på bifogade ritning visat slag.After the mold has been prepared for casting - before the casting operation begins - rubber rail inserts of the type described in the Swedish patent specification.73 06727-4 must be applied to the mold. A trolley is used. of the kind shown in the accompanying drawing.
Denna vagn består av ett stativ 3l som upptar fyra stycken rälsgående hjul 32, vilka via kedja drives av en reverserbar hydraulmotor 33. Maskinen uppvisar vidare ett flertal hydraulcylindrar 34, 35 och 36 samt kassetter med utmatningsmekanism för plattorna 37. Därjämte finnes ett _ hydraulaggregat 38 för drivning av cylindrar och motor 33.This trolley consists of a stand 3l which receives four rail wheels 32, which are driven via a chain by a reversible hydraulic motor 33. The machine furthermore has a plurality of hydraulic cylinders 34, 35 and 36 as well as cassettes with discharge mechanism for the plates 37. In addition there is a hydraulic assembly 38 for driving cylinders and engine 33.
Vid start av motorn 33 rör sig maskinen framåt med maximal hastighet till dess att motorn 33 erhåller impuls för krypkörning. Därefter stannar motorn 33, varvid cylin- dern 34 aktiveras och via koniska tappar 42 på kolvstången' klämmer fast vagnen vid formen via ett centreringsrör under 8103828-34 denna. Kassetterna med plattor är därvid centrerade mitt över motsvarande anliggningsplattor i respektive form.When starting the engine 33, the machine moves forward at maximum speed until the engine 33 receives impulse for crawling. Thereafter, the engine 33 stops, whereby the cylinder 34 is activated and via conical pins 42 on the piston rod 'clamps the carriage to the mold via a centering tube below it. The cassettes with plates are then centered in the middle over the corresponding contact plates in the respective shape.
Vid aktivering av cylindern 34 och påverkan av gränslägebrytare (icke visade) startar en på kassetten befintlig motor 44, vilken påverkar en utmatningsmekanism 45 som består av ett vridbart kors 46 anordnat runt en vridaxel 47. På axelns 47 motsatta ände sitter en kamskiva 48, vilken har fyra stycken nockar, som påverkar en mikro- brytare 49. Utmatningsmotorn 44 bringas därvid att röra sig l/4-dels varv vid varje ny impuls och stannar vid påverkan av mikrobrytare 49. När utmatningsmotorn 44 rört sig l/4-dels varv och avgivit en platta 59, varjämte mikrobrytaren 49 pâ- verkats startas cylinderns 34 returrörelse. Då nämnda cylin- der intagit sitt utgångsläge påverkas ytterligare gränsläge- brytare (icke visade), varvid drivmotorn 33 startar och ut- för krypkörning. Därefter aktiveras cylindern 35, vilken via koniska tappar 42 på kolvstången klämmer fast vagnen vid formen. Respektive cylinder 36 för fasttryckníng av plattor är därvid centrerad mitt över respektive i formen införd platta. Efter aktivering av cylindern 35 samt påver- kan av ytterligare en gränslägebrytare (icke visad) startar respektive cylinder 36 som via en avfjädrad stansdyna 52 i formen klämmer fast respektive införd platta. Därefter på- börjas först cylinderns 36 och därefter cylinderns 35 retur- rörelse. Vagnens drivmotor 33 startar därefter för förnyad frammatning med maximihastighet.Upon actuation of the cylinder 34 and actuation of limit switch (not shown), a motor 44 present on the cassette starts, which actuates a discharge mechanism 45 consisting of a rotatable cross 46 arranged around a rotary shaft 47. On the opposite end of the shaft 47 is a cam 48, which has four cams which act on a microswitch 49. The output motor 44 is thereby caused to move 1/4 of a revolution at each new impulse and stops at the action of a microswitch 49. When the output motor 44 moves 1/4 of a revolution and delivered a plate 59, and the microswitch 49 is actuated, the return movement of the cylinder 34 is started. When the said cylinder has assumed its initial position, further limit position switches (not shown) are actuated, whereby the drive motor 33 starts and performs creep driving. Then the cylinder 35 is activated, which via conical pins 42 on the piston rod clamps the carriage to the mold. The respective cylinder 36 for pressing plates is then centered in the middle over the respective plate inserted in the mold. After activation of the cylinder 35 and actuation of a further limit position switch (not shown), the respective cylinder 36 starts which clamps the respective inserted plate via a sprung punch pad 52 in the mold. Then the return movement of the cylinder 36 and then the cylinder 35 is started. The carriage's drive motor 33 then starts for re-feeding at maximum speed.
Vagnen är försedd med ett påkörningsskydd 56, vilket vid stöt mot hinder bryter drivmotorn.The trolley is equipped with a collision protection 56, which breaks the drive motor in the event of an obstacle.
Såsom torde ha framgått av det ovan angivna åstadkom- mer den beskrivna maskinen såväl noggrann applicering av plattorna i formen som ändamålsenlig tätning av formen för att det efterföljande gjutförloppet skall kunna äga rum helt invändningsfritt.As should have been apparent from the above, the described machine ensures both accurate application of the plates in the mold and appropriate sealing of the mold so that the subsequent casting process can take place completely without objection.
För att effektivisera nämnda tätning kan på särskilt sätt utformade plastkilar (icke visade) komma till användning.In order to make said seal more efficient, specially designed plastic wedges (not shown) can be used.
