The invention provides a control method and device for coal mine crawler-type mining equipment, and the method comprises the steps: obtaining a to-be-steered direction of the coal mine crawler-type mining equipment, and obtaining a to-be-advanced direction of the coal mine crawler-type mining equipment, then a first driving mechanism in the first electric traction system is controlled to drive a first crawler-type walking mechanism on the same side as the to-be-steered direction to move in the to-be-marched direction, and a second driving mechanism in the second electric traction system is controlled to drive a second crawler-type walking mechanism on the different side from the to-be-steered direction to move in the to-be-marched direction; the movement distance of the second crawler-type walking mechanism is greater than that of the first crawler-type walking mechanism, so that the advancing and steering of the coal mine crawler-type mining equipment are controlled based on the first electric traction system and the second electric traction system, and the rapid maneuverability of the coal mine crawler-type mining equipment is enhanced; the crawler-type mining equipment for the coal mine can accurately run according to the to-be-marched direction and the to-be-steered direction.
Description
technical field [0001] The present application relates to the technical field of coal mine mining equipment, in particular to a control method and device for coal mine crawler mining equipment. Background technique [0002] At present, the traction system of large-scale mining equipment in coal mines is generally a hydraulic traction system. The entire traction system is composed of a manual hydraulic valve, a hydraulic motor, a reducer and a crawler-type walking mechanism, and the manual hydraulic valve is divided into two hydraulic valves on the left and right, which can realize Independent control of the two tracks of the traction system, thereby controlling the steering of the mining equipment. In the related art, due to the low operating efficiency and slow response speed of the relevant hydraulic traction system, it is no longer satisfied with the development of the existing power electronics and motor speed regulation technology. Contents of the invention [0003] ...
