Abstract

The invention provides an intelligent control device and method for walking of a coal mining machine. The intelligent control device and method are suitable for coal mining machines. The intelligent control device comprises a coal cutting roller motor current transducer, a coal mining machine traction motor current transducer, a roller rotation-speed transducer, a stress transducer, a vibration transducer installed on a coal cutting rocker arm, a laser sensor, a hall switch, a sensor controlling upward displacement of a hydraulic shaft, a master controller, a variable frequency driver and a traction motor. All the components of the intelligent control device are used for detecting all parts of the coal mining machine, and the coal mining machine is controlled to only operate through monitor data. The mechanical failures caused when the coal mining machine is in contact with rock stratums or faults in the coal cutting process are avoided. Meanwhile, it is guaranteed that automatic control over the process that automatic control over reciprocating coal cutting by a coal face of the coal mining machine is achieved.

Description

technical field [0001] The invention relates to an intelligent control device and method, in particular to an intelligent control device and method for a coal shearer used on a coal shearer. Background technique [0002] Drum shearer is currently the most widely used coal mining equipment in coal mines. The operation control of the shearer mainly includes cutting drum control, rocker arm control and travel control. These three controls are critical to efficient and safe mining. Because the walking movement of the drum shearer is carried out on a fixed track, the control of coal burning is generally considered to be relatively simple, so there is less research. But in fact, the walking control of the shearer is related to coal mining efficiency and equipment safety. If the walking speed is too slow, it is not conducive to efficient coal mining. If the walking speed is too fast, it will cause excessive force on the coal cutting rocker arm due to coal cutting resistance. And ...
