Description

작업기계의 제어장치
본 내용은 요부공개 건이므로 전문내용을 수록하지 않았음
제1도는 본 발명에 의한 실시예의 제어장치를 도시하는 블록도, 제2도는 제어장치의 제어시스템을 주로 도시하는 블록도, 제3도는 한개표인 제어량과 부하사이의 관계를 도시하는 특성도.

Claims (3)

  1. 제어기가 작업기계레버의 조작입력에 의해 기능을 실행하는 유압장비를 제어하는 작업기계의 제어장치에 있어서, 상기 제어기는 제어량이 상기 작업기계레버의 개도에 따라 출력될때 상기 유압장비내의 오일파이프라인 속에 배치된 유압센서에 의해 검출된 유압에 따라 한계제어량을 조절하는 수단과, 그리고 상기 한계제어량이 측정값과 일치하도록 한계제어량의 표를 이동시켜 상기 한계제어량을 수정하는 수단을 구비하는 것을 특징으로 하는 작업기계의 제어장치.
  2. 제1항에 있어서, 상기 한계제어량이 한계제어량의 표를 이동시켜 수정될때 정확한 부하의 역치가 세트되고, 부하가 상기 역치보다 더 큰지 아닌지에 관한 결정결과에 따라 수정값이 변경되는 것을 특징으로 하는 작업기계의 제어장치.
  3. 제2항에 있어서, 부하가 특정한 역치보다 더클때 출력값은 작업기계레버의 출력이고, 부하가 상기 역치보다 더작을때 출력값은 부하한계값 ±수정값인 것을 특징으로 하는 작업기계의 제어장치.
    ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.
