Abstract
The present invention discloses a method and device for guiding and positioning the anchor arm of a continuous miner, which relates to the technical field of anchor arm positioning. The main purpose is to achieve precise control of the anchor arm of a continuous miner, so that the insertion position of the anchor is highly consistent with the process design, and the support quality of the excavation working face is improved. The method comprises: when a displacement signal is received, switching to a coarse adjustment mode; according to the displacement signal, adjusting the span width of the anchor arm so that the span width of the anchor arm reaches a preset threshold range; when a coordinate signal is received, switching to a fine adjustment mode; according to the coordinate signal, adjusting the span width of the anchor arm, and accurately positioning the span width of the anchor arm to the preset threshold. The present invention is suitable for guiding and positioning the anchor arm of a continuous miner.
