Definitions

  • the invention relates to a bucket chain excavator with buckets guided on a chain for use in open-cast mining systems, the chain being drivable by means of a drive assigned to the bucket chain excavator, and to a method for regulating the drive of the bucket chain excavator.
  • the aim of the invention is therefore to provide a bucket ladder excavator with less wear and thus less downtime than is the case with known bucket ladder excavators. It is also a goal to provide a bucket ladder excavator operating method that reduces wear.
  • the object is achieved according to the invention by a bucket ladder excavator for use in opencast mining systems according to claim 1 and a method according to claim 5.
  • the bucket chain excavator has buckets guided on a chain, the chain being driven or being drivable by means of a drive assigned to the bucket chain excavator.
  • the speed of the chain is measured without contact.
  • it is provided in particular to regulate this drive as a function of measured values obtained by the contactless speed measurement. In this way, it is possible to largely regulate the acceleration forces that arise during the ongoing and even constant operation of the bucket chain. This significantly reduces wear on the chain and leads to a significant reduction in downtimes of the bucket chain excavator.
  • the derivation of the speed of the chain is determined, in particular by means of a differentiator. It is special The advantage of regulating the derivation of the speed of the chain to a predetermined setpoint. In this way, the wear on the chain can be significantly reduced compared to a pure speed control.
  • reference numeral 1 denotes a bucket ladder excavator which has a grave member 9 guided on ropes 10, 11, 12, 13.
  • a boom 7 with a counterweight 8 is provided for weight compensation.
  • buckets 2 guided on a chain 3 are guided to break down material to be mined.
  • the chain is driven by means of a drive 5 arranged in a so-called machine house 6.
  • a non-contact speed measuring device 4 is arranged above the drive 5 and measures the speed of the chain 3 without contact.
  • the speed measuring device works according to the microwave Doppler radar principle and delivers e.g. continuously a speed proportional frequency of approx. 62 Hz / m / s. This speed-dependent frequency is fed to a frequency / analog converter, which generates a speed-proportional standard signal 0 ... 10 V or 4 ... 20 mA.
  • Other non-contact speed measuring devices such as ultrasound devices, can also be used as speed measuring devices.
  • the non-contact measured speed signal is differentiated and the drive is regulated by means of a controller in such a way that the derivation of the speed of the chain corresponds to a predetermined setpoint.
  • a setpoint for the derivation of the speed of 0 is specified.
  • PI or PID controllers and more complex controllers can be used as controllers.
  • the speedometer is attached to the roof of the machine house 6 of the bucket chain excavator 1 above the chute 15 with the direction of the bucket ladder tip. The running chain is measured. The reflection of the high-frequency radiation emitted by the radar, which is necessary for determining the speed, advantageously takes place through the largest irradiated area of the bucket back.
  • the particularly advantageous arrangement of the speed measuring device in the area of the drive means that runtime effects of the power transmission on the elongated element chain do not falsify the measurement result, ie the direct relationship between the Turas shape and the chain speed is recorded.
