Research On Profiling Cutting Theory Of Longitudinal Axis Type Roadheader

There are two kinds of roadheader according to mode that roadheader acts on section of laneway: Tunneling Boom Machine (TBM) and partial-size tunneling machine. Nowadays, partial-size tunneling machines are used widely in mining production in our country and abroad, main research object in this paper is boom-type roadheader that widely used in laneway excavation in underground coal mine, main problems which are discussed are how to finish laneway section automatic shaping of boom-type roadheader automatically.In this paper, partial-size tunneling machine of EBZ-160 is made as an example. Introduced the partial-size tunneling machine on the structure and work principles, getting the largest angle of the cantilever and the vertical plane when the cutting head movement to the border roadway, and getting the numerical of every tank when the partial-size tunneling machine was moved in accordance with roadway we gived, and putting the method that use numeric hydraulic cylinders to achieve automatic control of tunneling machine. Finally, using Pro/e and Adams two kind of software completed motion simulation and motion analysis.
