Definitions

  • the invention relates to a device for measuring two opposing roller conveyors of a continuous casting installation, with a measuring body which can be moved through the profile between the roller conveyors and which has opposing contact surfaces which contact the lateral surfaces of the rollers and which are formed from elastically deformable spring strips, in particular spring steel strips the contact surfaces can be pressed against the lateral surfaces of the rollers by pressure means arranged between them, with at least one distance change measuring device.
  • a device of this type is known from EP-AI 0 028 215. With this device, the distance between two opposing roller conveyors can be exactly determined, it is also possible to measure the distance of the roller conveyors even with rollers not exactly oppositely arranged and with roller conveyors with different roller pitches over their longitudinal extension and with changing curvature conditions.
  • the object of the invention is to design a device of this type in such a way that it can be used for measuring roller conveyors in which the roller distance of the opposing rollers is exactly correct, but one or more pairs of rollers are offset from other pairs of rollers.
  • the distance change measuring device which extends essentially in the direction of movement of the device, is provided on one of the spring bands and this distance change measuring device is assigned to two points of this spring band, which are spaced apart in the direction of movement, for measuring a change in distance between these two points is.
  • At least one distance change measuring device is provided on each of the two spring bands, which is opposite one another perpendicular to the direction of movement of the device. This makes it possible to clearly differentiate a pair of rollers offset with a single passage of the device through the roller tracks from a distance error of only one roller of the roller tracks.
  • Each distance change measuring device is advantageously inserted between two brackets mounted on the inside of the spring band, whereby at least one of the brackets is expediently designed as a console approximately perpendicular to the contact surface of the spring bands, which is extended to the vicinity of the opposite spring band, and furthermore the Distance change measuring device is inserted between the end of the console and another bracket.
  • Inductive displacement sensors have been shown to be particularly suitable for the rough steelworks operation in the device according to the invention.
  • Strain gauges attached to the spring band are used for particularly precise measurements.
  • FIGS. 1 to 4 show a device according to the invention in a schematic representation in a side view between two tube tracks.
  • FIG. 5 shows a further embodiment of the device according to the invention.
  • the device 3 for measuring the roller conveyors is inserted between the roller conveyors 1 and 2 of a strand guide of a continuous casting plant.
  • the device expediently has a coupling piece, not shown, by means of which it can be fastened by means of a coupling to a starting strand head of a starting strand for the purpose of pulling between the roller tracks 1 and 2.
  • the device has two contact surfaces 6 which come into contact with the lateral surfaces 4 of the rollers 5 and which lie on the outside of elastically deformable spring bands 7, such as spring steel bands.
  • the spring steel strips are pressed against the lateral surfaces 4 of the rollers 5 by pressure means 8 arranged between them, for example by spring pots or hydraulic or pneumatically actuated pressure means.
  • the distance 9 of the pressure medium 8 in the longitudinal direction 10 of the roller tracks or in the direction of movement 11 of the device corresponds approximately to the distance 12 of the axes 13 of the rollers 5. Since the axes 13 of the rollers 5 are closely adjacent in continuous casting plants, on the other hand at the outlet end If the system is located at greater distances, an average value should be chosen.
  • brackets 15 are provided which are rigidly connected to the spring steel strip and between which a distance change measuring device 16 which extends essentially in the direction of movement 11 of the device 3 is inserted.
  • the distance change measuring device 16 illustrated in the figures is designed as an inductive displacement sensor.
  • the brackets 15 are designed as brackets directed approximately perpendicular to the contact surface of the spring bands, on which the distance change measuring devices 16 are articulated without play.
  • the distance 17 of the brackets 15 corresponds approximately to the distance 12 of the axes 13 of the rollers 5 of one of the roller tracks 1, 2, again a mean value of all the distances of the roller axes of a strand guide track being selected as the holding distance 17.
  • the device according to the invention which is connected to a Device according to EP 0 028 215 A1 can be coupled, a roller offset 18 can also be determined, although the distance 19 of the rollers lying opposite one another corresponds exactly to the ideal dimension for all rollers 5.
  • the brackets 22 are designed as brackets directed in the direction perpendicular to the contact surface 6 of a spring steel strip 7 and projecting into the vicinity of the opposite spring steel strip 7.
  • the distance change measuring device is inserted between the ends 23 of the brackets 22. Due to the length 24 of the brackets, the change in distance is increasingly displayed by the distance change measuring device 16, so that the device 3 operates with a very high degree of accuracy.
  • a strain gauge can also be applied, for example glued, directly to the spring steel strip 7, the longitudinal direction of the strain gauge being directed parallel to the direction of movement 11 of the measuring device 3.
  • the invention is not limited to the exemplary embodiment shown, but can be modified in various ways.
  • the distance change measuring device 16 always detects or measures a distance change between two points of one of the spring steel strips 7 that are spaced apart in the direction of movement 11.
  • the spring steel strips 7 can exactly follow the curvature 21 of the roller conveyors, the spring steel strips 7 must have at least a length corresponding to three times the distance 12 between two adjacent rollers 5, so that each spring steel strip 7 is in contact with at least three rollers 5 of a roller conveyor 1 or 2 . It is advantageous if a writing instrument recording the measurement record of the distance change measuring device 16 is arranged on a box mounted on the coupling piece. However, it is also possible to transmit the measured values to the outside using a trailing cable or wirelessly by radio.
