Abstract

1504861 Maintaining constant feed force in drilling machines ROCK FALL CO Ltd 10 March 1975 [26 March 1974 11 May 1974] 13256/74 and 20933/74 Heading E1F A drilling machine 3 (particularly on a marine platform 1) is slidably mounted and suspended on a frame structure 2 from a cable 4 attached to a winch 5 and carries weights 8 to determine the feed force; the cable passes over pulleys 6 and 7 and means are provided to move one of the pulleys to increase and decrease the effective length of the cable thereby maintaining a constant feed force e.g. to compensate for movement of a platform caused by swell. As shown, pulley 7 is mounted to move with a piston 10 which is slidable within a cylinder 11 secured to the frame structure 2 and a pressure source directs fluid to the cylinder via an adjusting valve 16, a gauge 15, and a quick release valve. The pressure set by valve 16 determines the effective feed force and upward or downward platform movements of up to 0.75 metre will be compensated for by movements of the piston within the cylinder. In a further embodiment (Fig. 2 not shown) pulley 7 is mounted directly on frame 2 and an additional piston mounted pulley is mounted on the platform.
