Research On Cutting Forming Control Of Thecantilever Boom-type Roadheader

Now,The boom-type roadheader is widely used in the mining of our country.Along with the mining exploitation capability have increased, But the severe problem of the mining work mismatch have appeared, the safety and efficiency become focal point of mie. The boom-type roadheader is, a engine driver operate it by hand. Because the driver couldn't control the cutting condition, the quality of the surface of forming is not better control, the intensity is larger, and the safety could not ensure. Now We don't find any useful articles on abroad and the domestic research is less. So the realizations of the automatic forming cutting have the actual value and engineering value.Based on the EBZ-200cantilever boom-type roadheader in the laneway, the chief task of this subject makes use of PLC to achieve automatic forming control. The automatic forming controls cantilever which drives cutting head. It contains establishing the control mathematic model by the relationship between cantilever and section size, using angle sensor and automatic checkout equipment. The regular shape and size of the section can be done. The main contents include theme of automatic forming control and systen design, function blocks summary of system and debug program, PLC software program, industry experiment, and last put forward the control solution for intelligent control of the boom-type road-header.
