Abstract

Valjački stan (1), koji definira os valjanja, a obuhvaća- fiksnu vanjsku strukturu (13), - tri radnja valjka (2) postavljena u držače za valjke (3), taj ležaj se može pomicati iz radnog položaja unutar fiksne strukture (13), na spomenutoj osi valjanja, do položaja bočnog vađenja (3') izvan fiksne strukture (13) za zamjenu radnih valjaka (2), gdje za svaki radni valjak (2) postoji barem jedna odgovarajuća hidraulička kapsula (4', 4") čvrsto fiksirana za fiksnu strukturu (13), gdje je barem prva hidraulička kapsula (4") dvotaktnog tipa čime omogućuje, dodatno uz prvi radni takt za prilagodbu radijalnog položaja odgovarajućeg radnog valjka (2), drugi takt udaljavanja od osi valjanja, radi olakšavanja bočnog vađenja držača valjaka (3), gdje je druga hidraulička kapsula (4') horizontalno postavljena da omogući vađenje držača valjaka (3) duž horizontalne ravnine. Patent sadrži još 12 patentnih zahtjeva.

Claims (13)

1. Valjački stan (1), koji definira os valjanja, a obuhvaća - fiksnu vanjsku strukturu (13), - tri radnja valjka (2) postavljena u držače za valjke (3), taj ležaj se može pomicati iz radnog položaja unutar fiksne strukture (13), na spomenutoj osi valjanja, do položaja bočnog vađenja (3’) izvan fiksne strukture (13) za zamjenu radnih valjaka (2), gdje za svaki radni valjak (2) postoji barem jedna odgovarajuća hidraulička kapsula (4’, 4") čvrsto fiksirana za fiksnu strukturu (13), gdje je barem prva hidraulička kapsula (4") dvotaktnog tipa čime omogućuje, dodatno uz prvi radni takt za prilagodbu radijalnog položaja odgovarajućeg radnog valjka (2), drugi takt udaljavanja od osi valjanja, radi olakšavanja bočnog vađenja držača valjaka (3), gdje je druga hidraulička kapsula (4’) horizontalno postavljena da omogući vađenje držača valjaka (3) duž horizontalne ravnine.
2. Valjački stan prema zahtjevu 1, gdje postoje dvije prve hidrauličke kapsule (4") nagnute u odnosu na okomitu os koja prolazi kroz os valjanja za unaprijed određeni prvi kut i koje su tako postavljene da omoguće vađenje držača valjaka (3) duž horizontalne ravnine na strani suprotno od druge hidrauličke kapsule (4’).
3. Valjački stan prema zahtjevu 2, gdje je unaprijed određeni prvi kut oko 30°.
4. Valjački stan prema zahtjevu 2, gdje je za svaki radni valjak (2) predviđena odgovarajuća kontrolna ekstenzija (5, 5’, 5"), prva ekstenzija (5) je okomito smještena iznad radnog položaja držača valjaka (3), i dvije druge ekstenzije (5’, 5") su postavljene nagnuto u odnosu na okomitu os za drugi kut od oko 60°.
