Definitions

  • This invention relates to tunnelling, ripping, heading and other excavating machines.
  • an excavating machine said machine comprising a machine body and excavating means connected to said body by a mounting arrangement, the mounting arrangement being movable under manual control, relative to the body of the machine in a first direction, said movement automatically activating movement in a second direction, so that a predetermined excavation pattern results.
  • the movement in said first direction is rotational movement relative to the body of the machine. More preferably said rotation is about a longitudinal axis of the body.
  • the movement in said second direction is pivotal movement relative to the body of the machine.
  • the machine includes a cam operated driving arrangement for the mounting arrangement, the cam being profiled according to the shape of the excavation to be cut. More preferably the rotation of the cam is related to the movement of the mounting arrangement in said first direction.
  • said mounting arrangement is additionally capable of manually controlled movement in a third direction relative to the body. More preferably said third direction is longitudinally of the body of the machine.
  • the present invention also provides a method of excavating comprising providing an excavating machine having a machine body and excavating means connected to said body by a mounting arrangement,and effecting under manual control movement of the excavating means relative to the body in a first direction, said movement automatically activating movement in a second direction so that a predetermined excavation pattern results.
  • a tunnelling machine having control means in accordance with the present invention comprises a main body equipped with a turret 15 mounted for sliding movement forward and aft of the machine on a turret slide. Such movement enables the position of cutter drum 21 to be advanced as the cutter drum 21 cuts into the face of the tunnel.
  • Turret 15 is also mounted for rotational movement about the machine's longitudinal axis, this movement being effected by means of a slewing ring gear driven by four pinion gears (not shown).
  • boom 19 is capable of pivotal movement about turret 15. This pivotal movement is effected by hydraulic rams 23 and 25.
  • the plane about which the pivotal movement is achieved can be altered by the above-mentioned rotational movement of the turret about the machine's longitudinal axis.
  • cam 301 which is profiled so as to produce the desired boom movements in the following way.
  • Engaging surface of cam 301 is a cam follower 303.
  • cam follower 303 moves substantially vertically under control of cam 301.
  • Cam follower 303 is linked to a potentiometer.305 the setting of which depends upon the vertical position of cam follower 303.
  • Potentiometer 305 is connected to an arrangement 306 which performs an electronic comparison as well as slave control of a further potentiometer 307 by potentiometer 305.
  • Potentiometer 307 controls certain boom movements and together the movements of the boom are controlled by the two potentiometers.
  • hydraulic rams 23 and 25 are extended or retracted according to signals passed from arrangement 306 to a valve assembly 309.
  • Turret 15 is rotated h ydraulically/under the-control of the driver, thus rotating cam 301.
  • cam 301 During rotation of cam 301 an engagement of that part of the surface of cam 301 from F to F (the lower portion of cam 301 as seen in Figure 1) the turret and boom carry out the movements which enable the cutter to effect the cutting of the tunnel floor.
  • cam follower 303 engages the circular outer portion 301 of the cam the motion is such that the cutter effects the cutting of the tunnel walls.
  • the cam follower 303 is caused to engage the inner cam surface 323 and during rotation of the cam the inner central portion of the tunnel (movement of the cutter from G to H as seen in Figure 2) is effected.
  • the shape of the tunnel to be cut may be varied by altering the shape of the cam.
  • Control means in accordance with the present invention may be fitted to excavating machines other than tunnelling machines, for instance, ripping or heading machines.
