Abstract

Här beskrivs ett arrangemang för att styra förflyttningshastigheten hos ett slagorgan (6) som är anordnat att förflyttas i en borrmaskins borrmaskinshus (1), där slagorganet (6) innefattar en bromsyta (13). Borrmaskinhuset (1) innefattar en bromskammare (11) utformad att inhysa en fluid avsedd att bromsa slagorganets (6) förflyttningshastighet inuti borrmaskinhuset (1) samt en kanal (15) utformad att leda fluid från bromskammaren (11). Arrangemanget är utformat att styra slagorganets (6) förflyttningshastighet genom att anpassa det tryck som fluiden i bromskammaren (11) påverkar slagorganets (6) bromsyta (13) med genom att endast leda fluid från bromskammaren (11) när en referenspunkt (17) hos slagorganet (6) befinner sig framför en första position (19) i bromskammarens (11) axiella utsträckningsriktning (E).Här beskrivs även en borrmaskin innefattande arrangemanget och en metod för att styra förflyttningshastigheten hos ett slagorgan (6) som är anordnat att förflyttas i en borrmaskins borrmaskinshus (1).An arrangement is described here for controlling the speed of movement of a percussion means (6) which is arranged to be moved in a drilling machine housing (1) of a drilling machine, the percussion means (6) comprising a braking surface (13). The drilling machine housing (1) comprises a brake chamber (11) designed to house a fluid intended to brake the speed of movement of the percussion member (6) inside the drilling machine housing (1) and a channel (15) designed to conduct fluid from the brake chamber (11). The arrangement is designed to control the speed of movement of the percussion member (6) by adjusting the pressure with which the fluid in the brake chamber (11) affects the braking surface (13) of the percussion member (6) by guiding fluid only from the brake chamber (11) when a reference point (17) of the percussion member (6) is located in front of a first position (19) in the axial extension direction (E) of the brake chamber (11). drilling machine drilling machine housing (1).
