Description

' 464 527 h 2 armarna befinner sig på olika avstånd från borrhuvudets rotationsaxel och på olika avstånd från tunnelfronten. Härigenom är det möjligt att uppnå en större ökning av tunneldiametern än vad som skulle vara fallet om borrverktygen satt på samma avstånd från rotationsaxeln. Då tunneln skall drivas med normal diameter manövreras hydraulcylindrarna så att armarna ll,l2,l3,14 fälls in till sina inaktiva lägen. Borrhuvudet är dessutom försett med icke visade spârrorgan som spärrar armarna i utfällt läge eller i infällt läge så att hydraulcylindrarna inte behöver användas för att hålla armarna på plats.

Claims (3)

3 464 527 Patentkrav:
1. Tunnelborrningsmaskin innefattande ett relativt en tunnel (3) fixerbart hus (1), ett relativt sagda hus roterbart borrhuvud (4) försett med ett antal borrverktyg (6) för bearbetning av en tunnelfront (7) samt en drivmotor (5) för rotering av sagda borrhuvud, k ä n n e t e c k n a d a v att sagda borrhuvud (4) innefattar ett antal med borrverktyg (4l,42,43,44) försedda svängbara armar (ll,l2,l3,14) invid borrhuvudets periferi, varvid sagda armar är svängbara medelst hydraulcylindrar (2l,22,23,24) mellan ett infällt inaktivt läge och ett utfällt läge för bearbetning av tunnelväggen utanför dess normala diameter.
2. Tunnelborrningsmaskin enligt patentkravet l, k ä n n e t e c k n a d a v att sagda armar (ll,l2,l3,l4) är så svängbara relativt det övriga borrhuvudet (4) att borrhuvudets rotation medför att krafterna från tunnelväggen under borrning efter armarnas utsvängning håller armarna kvar i utfällt läge.
3. Tunnelborrningsmaskin enligt patentkravet l eller 2, k ä n n e t e c k n a d a v att sagda borrverktyg (4l,42,43,44) på de olika armarna (ll,l2,l3,l4) i utfällt läge befinner sig på olika avstånd från borrhuvudets (4) rotatíonsaxel (10) samt på olika avstånd från tunnelfronten (7).
