Fast, safety and efficiency are the direction of the coal roadway support technology in China, with the development of the roadway support technology, the research of integrated driving units which is suitable for conditions for China’s coal mines is becoming the research focus of mine. Based on the inefficiency, labor-intensive and other issues in the process of anchor rod and anchor rope support setup, this dissertation has been finished based on the support of Shandong UROICA Automatic Equipments Stock Limited Corporation with the cooperated item heading of "The Research on Integration Operation Devices with Hole Drilling and Anchor rope". The main aim of this dissertation is to design a set of mechanical device which includes drilling, anchor rod and anchor rope installation and according tension to increase the working efficient, improve the installation accuracy, decrease the labor strength and improve working conditions.The structure design of drilling device has been completed on the base of d drilling anchor integration operation devices platform, and organic combination of drilling device and drilling anchor integration operation devices platform has been achieved in the paper. By choosing reasonable transportation device, structure design of cable installation device has been completed. With the use of finite element method and ANSYS, the analysis of structure stability to drilling anchor integration operation devices platform has been carried out. Furthermore, by analyzing the mechanical properties of the operation device platform beam, the structure of beam has been optimized to ensure the rationality of the whole organization.Using UG three-dimensional modeling software and based on virtual prototype technology, the modeling of anchor rope installing the unit has been completed, which has been imported into ADAMS, and joint simulation of UG and ADAMS has been realized, what’s more, kinematics modeling and simulation to cable installation mechanism have been carried out. With the method of Lagrange dynamics analysis, the kinetic simulation has been carried out to drilling anchor integration operation devices and cable installation device, besides, the items effecting unstable dynamics has been analyzed, which provides theoretical foundation for the optimal design of drilling anchor integration operation devices and cable installation device.The parts of the device are being processed and manufactured by Shandong UROICA Automatic Equipments Stock Limited Corporation, and a test platform for the entire device has been built. As a matter of time, the welding for large parts and assembly for the whole device are still in progress.The test platform used in this system has been built by Shandong UROICA Automatic Equipments Stock Limited Corporation, the processing for some parts of anchor cable installation device have been completed. In this dissertation the structure design of drilling anchor integration operation devices and anchor cable installation device have been finished and the device structure has been optimized by three-dimensional modeling, combining kinematics, dynamics and finite element method for structure. This method provides for structure design and optimization methods for a similar device based on virtual prototype technology.
