Abstract

1472590 Tunnelling apparatus ANDERSON MAVOR Ltd 21 Oct 1975 [5 Nov 1974] 47742/74 Heading E1F In a tunnelling apparatus having a tubular, advanceable shield 1 in which is located a base plate 3 that is adapted to support a cutting machine and is slidably mounted on side runners 27, 28 on the shield 1 so that the base plate can be advanced and retracted relative to the shield, the base plate can be held stationary relative to the shield by means comprising laterally opposed hydraulic rams 33 of which the pistons carry clamping heads 30 that can engage lateral edge portions of the base plate 3 and the cylinders are connected to anchorages supported on regions of the shield so offset from the longitudinal axes of the rams as to prevent or reduce the transmission of pressure from the shield to the rams in a direction axially of the latter. Preferably each ram is upwardly inclined from the base plate, said anchorage for a ram is provided at or adjacent the upper end of an upstanding block 36 fixed to a platform and the platform is supported on a said region of the shield offset from the longitudinal axis of the ram. Each ram can be connected to the associated anchorage so as to be pivotable about an axis extending longitudinally of the shield. Each clamping head may be connected to the piston of the associated ram by a ball and socket joint 31 and may comprise a guide block that engages the upper face and side face of the base plate The side runners can be secured to the platforms and the rams may rest in cradles provided in the upstanding blocks 36. Hydraulic rams are provided for moving the base plate relative to the shield. The cutting machine which can be secured to the base plate may have a rotary cutter head-carrying, universally pivotable boom. The swinging movement of such a boom, which may be telescopic, may be limited by an annular cam mounted on the base plate and a co-operating cam follower on the rear end of the boom. A conveyer may be located below the base plate and supported therefrom as in the referred to Specification 1472589.
