Abstract
1,237,859. Boring earth and rock. ATLAS COPCO 6' A.B.' 23 Sept., 1969 [4 Oct., 1968; 4 Dec., 1968], No. 46733/69. Heading E1F. [Also in Division B3] A rotary rock drill comprises pressure fluid actuated chuck 21 comprising a rotatable housing 22 with an aperture to receive a drill string 19 and jaws 42 forgripping the drill string. The jaws are urged away from the drill string by spring plates 45, Fig. 2, and are surrounded by an elastomeric sleeve 35. When fluid from a conduit 26, Fig. 4, is supplied to a pressure chamber 40 the sleeve forces the jaws to grip the drill string. The rear ends of the jaws may be bevelled to present a smooth surface to the sleeve 35. Torque is transmitted from the chuck housing to the jaws by guide pins 43. The chuck is rotated by an hydraulic motor 46 and the assembly may be displaced vertically on a feed bar 11. In a modification, Fig. 5 (not shown) the spring plates are replaced by coil springs.
