Abstract:
1. A process for the joint control of a conveyor bridge comprising at least three segments controlled when traveling and moving from a linear starting position, as viewed from the top, into a linear end position, as viewed from the top, wherein each segment is equipped with one, two or a plurality of driven crawler traveling gears, each traveling gear comprising a rotor, and the segments are connected to each other in an articulated manner, the process comprising the steps of: a) detecting positions of both ends of the segments, aligned in a starting line, as viewed from the top, of a conveyor bridge before the moving process on terrain; b) calculating target coordinates for the control of the conveyor bridge with the intended movement sequence for each traveling gear of the segments of the conveyor bridge as a traveling gear-specific number of pulses corresponding to rotor revolutions; c) simultaneously switching on of drives of all traveling gears of the segments of the conveyor bridge; d) synchronously controlling the drives of all traveling gears, insofar as a higher-level adjustment by the angle monitoring is not activated; e) during the travel movement measuring a distance covered by each traveling gear; f) constantly measuring angle deviations from the straight line in a top view between two adjacent segments during travel movement, wherein occasionally with a lagging/excessive speeding over a defined window the traveling speed of a particular one of the crawler traveling gears is increased or reduced or maintained and/or the travel of other crawler traveling gears is slowed down or interrupted; g) providing a lateral slope compensation for guaranteeing in each case a vertical position of all segments in relation to the travel level between the traveling gear and the support frame of each segment; and h) providing a fine alignment of inner segments of the segments after reaching target coordinates through two outer segments of the segments of the conveyor bridge.
