Abstract
The invention relates to a tunnel boring machine (103) in which the thrust cylinders (109) acting on a cutting wheel (106) are controlled by means of the direct input of coordinate values of a desired total center of pressure (151) in a coordinate system (154, 157) relating to the tunnel boring machine (103).
Claims12
A tunnel boring machine with a cutting wheel (106), comprising:
- a number of driving presses (109) with which the cutting wheel (106) can be moved in a driving direction,
- a driving press control unit (115) with which the driving presses (109) or groups of driving presses (109) can be controlled,
- visualization means (148) which are configured to visualize an actual total center of pressure (166) resulting from the pressure effect of the driving presses (109) or groups of driving presses (109),
- input means (130) configured to specify a desired total driving force (Ftot), in that the visualization means (148) are configured to display a desired total center of pressure (151) and the actual total center of pressure (166), and
- an operating unit (118) connected with the driving press control unit (115) for influencing the actual total center of pressure (166) by changing coordinate values (CoTx, CoTY) of the desired total center of pressure (151) in a coordinate system (154, 157) related to the tunnel boring machine (103) for at least approximating the actual total center of pressure (166) to the desired total center of pressure (151), and in that the driving press control unit (115) is configured to convert the change of coordinate values (CoTx, CoTY) of the desired total center of pressure (151) into pressure value changes when controlling the driving presses (109) or groups of driving presses (109) and adjust them accordingly.
