Definitions

  • the invention relates to a road milling machine or a machine for the exploitation of deposits, for example, deposits of coal, ores, minerals, etc. in opencast mining.
  • the road milling machines have a milling device which has a mechanically or hydraulically driven milling drum. Also known as surface miners machines for exploitation of deposits have a milling device with a milling drum, which is also referred to as a cutting roller in a surface miner.
  • the milling drum of the road milling machines and surface miners is equipped with tool holders for holding the milling tools.
  • the milling rollers of the road milling machines or machines for exploiting deposits have a predetermined working width, which corresponds to the width of the milling drum.
  • the problem arises that the surfaces to be machined may have an extent whose width corresponds to a multiple of the working width of the machine. Then it is necessary to mill for machining the entire surface of several adjacent strips. This requires a precise guidance of the machine, since the individual milling strips must be aligned exactly with each other. On the one hand, the milling strips should run so close together that no unprocessed area remains between the strips, on the other hand, the milling strips should not overlap, so that the productivity is not reduced. In practice, only a very small Overlapping is sought to ensure full machining of the area with high productivity.
  • the machining of the surface takes place in a plurality of successive milling strips by visual comparison between the dimensions of the machine and the surface to be machined by the machinist.
  • This adjustment is very tiring and tiring for the machinist because he has to control the machine along the many other tasks that he has to do, such as the coordination of material loading or leveling, the exact milling over the entire milling section.
  • the machinist always has the conflict that drifting off in the previously processed milling strip reduces the efficiency and drifting in the opposite direction results in the surface not being completely machined.
  • the US-A-4,041,623 describes a road milling machine with crawler tracks, which provides an automatic specification of the direction of travel. This requires, however, that a string is stretched, which is attached to along the desired FrasstMails spaced apart posts.
  • the control device for the steering device has a scanning device with a feeler element, which slides along the tensioned line.
  • the steering device for steering the chain drives is controlled so that the machine follows exactly the course of the string.
  • the US-A-5,362,176 describes a construction machine having means for determining the distance of the construction machine to a particular edge. These Device generates a control signal that is used to control the machine.
  • a road milling machine with a arranged between the front and rear drives milling device is for example from the US-A-3,414,327 known.
  • the invention is based on the object to provide a road milling machine or machine for the exploitation of deposits, which allows efficient processing of even broad areas.
  • the road milling machine or machine for exploiting deposits according to the invention is characterized in that an efficient machining of a wide area does not require any preparatory measures, for example the tensioning of a string or the like.
  • the machine according to the invention can be handled as the known machines, but allows automatic guidance of the machine, so that the individual milling strips are exactly next to each other.
  • the machine according to the invention has a device for detecting the course of a milling edge of a milling strip, wherein the means for detecting the course of the milling edge means for detecting the distance between at least one reference point of the machine and the milling edge.
  • the device for detecting the profile of the milling edge interacts with the means for steering the track drives so that the machine follows the course of the milling edge.
  • the distance between the at least one reference point of the machine and the milling edge can be adjusted so that the side-by-side milling strips are exactly aligned with each other.
  • the distance to be set depends on where the at least one reference point of the machine is located.
  • the definition of only one reference point is sufficient. But it can also be set several reference points to determine the distance at different locations. These values can be evaluated statistically, for example, the mean value can be formed. Also, the milling edge can be assigned to one or more reference points.
  • the means for detecting the course of the milling edge first means for detecting the distance between a reference point, preferably arranged at the lower end of the left edge protection, more preferably at the front lower end of the left edge protection of the milling machine and second means for detecting the distance between a reference point, which is preferably arranged at the lower end of the right edge protector, particularly preferably at the front lower end of the right edge protector, wherein the first or second means are activated depending on the direction of travel of the road milling machine . can be deactivated.
  • the device for detecting the profile of the milling edge has a device for monitoring the distance, which compares the measured distance between the at least one reference point of the machine and the milling edge with a desired distance.
  • the means for monitoring the distance then acts in such a way with the device for steering the crawler tracks that the crawler tracks are steered such that the measured distance corresponds to the desired distance.
  • the means for monitoring the distance is preferably designed such that this device only cooperates with the device for steering the crawler tracks when the distance between the at least one reference point and the milling edge is within predetermined limits. If the distance is outside predetermined limits, for example, outside the detection range of the means for detecting the distance or no value is determined for the distance, so there is no automatic control. In this case, an alarm can be given. The machinist can then control the machine by hand.
  • the means for detecting the distance between the reference point of the machine and the milling edge can be designed differently.
  • An embodiment of the machine according to the invention provides a mechanical scanning device with a mechanical probe element.
  • electrical or electronic scanning devices with electrical or electronic "feeler elements" can also be provided according to the invention.
  • the ultrasound sensors known from ultrasonic measuring devices or the capacitive sensors known from capacitive proximity switches can be used to determine the distance.
  • the known laser triangulation sensors are particularly suitable for detecting the milling edge.
  • cameras can be used with which the milling edge can be detected and the distance can be determined.
  • a device is provided with which the mechanical probe element can be moved in the horizontal plane. This makes it possible to introduce the probe element laterally to the vertical surface of the milling edge.
  • the means for detecting the distance having means with which the angular position of the shaft can be determined.
  • the device for moving the probe element in the horizontal plane preferably has means with which the probe element can be resiliently biased against the milling edge. This ensures that the probe element always rests against the milling edge, even if the milling edge is not flat.
  • the probe element is biased with a piston / cylinder assembly resiliently against the milling edge, which at the same time a method of the probe element in the horizontal plane allowed. But it is also possible to provide a spring to bias the probe element against the milling edge.
  • the reference point of the machine is preferably a point at the bottom End of the left or right edge protection is arranged. This has the advantage that the reference point is located directly next to the milling edge.
  • the reference point is a point which is arranged at the front end in the direction of travel of the left or right edge protector. This is the reference point in the direction of travel in front of the milling drum. If only the front track drive is steered, it is advantageous if the reference point lies directly in front of the milling drum, since then an uneven course of the milling edge is not copied exactly, but smoothed, and can be driven to the end of the milling track.
  • the reference point can also be set at a greater distance in front of the milling drum on the machine frame.
  • the steering device for steering the track drives can then be controlled in dependence on the distance between the old and the new milling edge.
  • means for further automation Detecting the position of the left and right edge protection provided.
  • one of the two edge protectors rests on the already milled surface, while the other edge protection rests on the surface that has not yet been machined.
  • the means for activating the first or second means for detecting the distance between the reference point and the milling edge cooperate with the means for detecting the position of the left and right edge protection, that those means are activated for detecting the distance associated with the edge protection, the is in the lower position while deactivating the other means for determining the distance associated with the edge guard which is in the upper position. This ensures that the distance to the milling edge is always determined on the side on which milling is also performed. It is therefore not necessary for the machine operator to specify on which side of the machine the distance is measured.
