Abstract:

Abstract:Aiming at the problems of complex geological conditions, limited space, low automation degree of driving and anchoring equipment and low driving efficiency in coal mine roadway driving face, a new crawler gantry drilling and anchoring robot is proposed, and its reliability is analyzed. The 3D model is built by SolidWorks, and the key parts are analyzed and calculated by ANSYS; The vibration characteristics of gantry type anchor drilling robot are deeply studied, and the first six natural frequencies are obtained, and the vibration modes are analyzed. The results show that the overall structure design of gantry drilling and anchoring robot is reasonable, the stiffness and strength meet the requirements, and it has strong stability and reliability.
