Definitions

  • the invention relates to a device for detecting the position of the cutting head of a tunneling or extraction machine.
  • a device for detecting the position of the cutting head of a tunneling or extraction machine In order to detect the position of the cutting head of a tunneling or extraction machine relative to a target profile to be cut, it has already become known to arrange radiation receivers on the frame of the cutting machine, which, together with the signals of a transmitter fixed in the path, allow the spatial coordinates of the longitudinal axis of the cutting machine to be determined.
  • additional devices for determining the swivel position of the cutting arm relative to the cutting machine were now based on the coordinates of the cutting head with the aid of additional signals and above all with signals closed.
  • the device according to the invention is characterized by a receiver which is oriented relative to the longitudinal axis and which can be attached in a distance, a transmitter for electromagnetic radiation in the wavelength range from 1 .mu.m to 10 cm on the cutting head and / or a cutting arm and a range finder for determining the distance at least one reference point on the cutting head and / or cutting arm from the receiver, and preferably a display device for the position of the cutting head relative to a desired profile to be cut.
  • a transmitter for electromagnetic radiation is now provided directly on the head or a reference point on the cutting arm, while taking into account the distance of this point from the receiver which is fixedly arranged in the route, allows an exact representation of the position of the cutting head in polar coordinates by means of a single angle determination express and use in a display device or as a control signal for automatic control of the tunneling or mining machine.
  • radiation is chosen for this purpose which shows less scatter than visible light and has a higher penetration capacity, etc. preferably electromagnetic radiation in a wave range of 1 .mu.m to 10 cm, which is longer than visible light.
  • the heat development can be exploited during the cutting work, since the chisels and the cutting head have a significantly higher temperature than the surroundings and thus act as infrared radiation transmitters.
  • the large temperature difference between the hot chisels of the cutting heads and the environment enables the use of relatively insensitive receivers, although there is usually no need for complex cooling of the receiver.
  • the receiver is preferably designed as a thermal imaging camera which is arranged in a fixed manner in the route and is aligned with the longitudinal axis of the route, for example using the laser beam guide beam which is usually used.
  • thermal imagers have a line scan and the video signal obtained in this way can be used directly with known electronic devices, displayed on screens and / or fed to a control device.
  • the design can also be such that the receiver is arranged pivotably and can be aligned to at least one reference point of the cutting head formed by the transmitter for determining the angle between a parallel line to the longitudinal axis of the line and the reference point of the cutting head.
  • the servo-motoric tracking of such a swiveling receiver and alignment with the transmitter immediately gives a measure of the angle to be measured. Together with the distance measured in a known manner, for example using infrared rays, the position of the cutting head can be displayed directly.
  • the transmitter it is advisable to arrange it near the axis of rotation of the cutting head, because then, based on the known geometry of the head and the known dimension of a head, together with the measured distance, the exact position of the cutting head in any rotational position of the same can be determined.
  • the distance can also be measured between the stationary receiver and the face itself, since the cutting head is in engagement with the face.
  • the transmitter designed as an infrared radiation transmitter is itself formed by the cutting head which is at the operating temperature.
  • the entire contour of the hot cutting head is detected with the receiver and the distance measurement could in this case be carried out by measuring the contour larger or smaller for a given dimension of the cutting head at different distances from the cutting head to the thermal imaging camera.
  • a reduction in the cutting head contour measured at a fixed focal length of the thermal imager corresponds to a greater distance from the thermal imager.
  • the display device advantageously contains a screen on which the position of the cutting head relative to the target profile can be displayed, the target profile display or the cutting head display depending on the distance of the cutting head from an infrared radiation receiver or the thermal imaging camera being changeable in size.
  • the scale representation on the screen can be maintained. This can be done in a simple manner in that the thermal imaging camera has a zoom lens which can be adjusted in focal length as a function of the distance of the cutting head.
  • the preferred embodiment of the device according to the invention is that the thermal imager is arranged in a fixed manner in the route, that the thermal image is scanned line by line in a manner known per se, and that the video signal obtained in this way is displayed by the display device and / or a control device for the movement the cutting head is fed.
  • FIG. 1 shows a schematic representation of the arrangement of the device in a distance
  • FIGS. 2 and 3 show the geometric conditions that apply to the determination of the spatial coordinates
  • FIG. 4 shows a schematic side view of the device according to FIGS. 1 and 5 the picture a display device which is connected to the arrangement according to FIG. 1
  • FIG. 6 shows a schematic illustration of the circuit arrangement required for the evaluation of the signals received.
  • a partial cutting machine 1 is shown within the route 2.
  • the cutting arm of this partial cutting cutting machine is designated 3 and has at its end two rotating cutting heads 4 which are rotatably mounted about the axis 5 extending transversely to the axis of the cutting arm.
  • a reference point 6 formed by an infrared transmitter is arranged on the cutting arm 3 near this axis 5.
  • a thermal imager 8, which is aligned in a corresponding manner on the laser path guide beam 9, is arranged in a stationary manner on an expansion frame 7.
  • the fixed receiver 8 determines the distance between the reference point 6 formed by an infrared transmitter on the cutting arm and the receiver 8.
  • the Cartesian coordinates of the reference system of the receiver are indicated by x, y and z, and two angles are measured relative to this coordinate system, as is the case here is explained in Figs. 2 and 3.
  • Fig. 2 the Cartesian reference system is shown with the origin at the measuring point of the thermal imager 8.
  • the xy plane of this reference system is oriented in a simple manner parallel to the route guide beam 9.
  • the reference point 6 of the cutting arm or cutting head is now in polar coordinates by the angle , and expressed the distance r.
  • Two angles and the distance between the origin of the reference system of the thermal imager 8 and the reference point on the cutting head or cutting arm are thus measured.
  • the outer contour of the cutting heads, designated by 10 in FIG. 1 is equally well known Entire be scanned by a thermal imager.
  • the angles to be measured are shown in Fig. 3.
  • the receiver 8 is in turn fixed on a removal frame 7 and oriented relative to the longitudinal axis of the line.
  • the angle 1 is measured in relation to the xy plane of the reference system of the receiver and therefore appears in relation to the angle V in Fig. 3 reduced by 90 °.
  • the angle is obtained in an analogous manner in the top view, not shown S starting from the x-axis of the reference system of the receiver.
  • the distance a from the receiver 8 to the face 11 can be measured, since this distance is only slightly different from the distance r when the receiver 8 is at a greater distance from the reference point 6.
  • the screen display shown in FIG. 5 can be obtained directly from the video signal of the thermal imaging camera obtained.
  • the screen of the monitor 12 is designated 13 and shows the target profile 14 of the route to be covered. The images of the cutting heads 4 can be seen within this target profile 14, the traces of the rotating chisels being clearly shown as essentially vertical lines.
  • FIG. 6 A circuit suitable for scanning the video signal of the thermal imaging camera is shown schematically in FIG. 6.
  • the thermal imager is also designated 8 here, as is the receiver.
  • the camera is fed signals for vertical and horizontal deflection via lines 15 and 16, respectively.
  • the video signal arrives via line 17 and Differentiator 18 to a comparator 19 and can be fed directly to the monitor 12.
  • this signal can also be fed to an image evaluation circuit 20.
  • Separate control signals can be obtained via lines 21 for the three-space coordinates of the position of the cutting head.
