Research On Automatic Drilling And Anchoring Unit Of Coal Mine Drilling Anchor Robot

Aiming at the problems of poor working environment,high labor intensity and low support efficiency existing in the support of underground bolt in coal mine,such as poor working environment,high labor intensity and low support efficiency existing in the support of underground bolt in coal mine,this paper puts forward a kind of coal mine driving robot systerm composed of driving robot,advanced supporting robot and drilling and anchoring robot,aiming at improving the supporting efficiency of underground coal mine,reducing the labor intensity of underground workers and liberating productivity to the maximum extent.This paper focuses on the research of automatic anchor drilling unit of anchor drilling robot.(1)The overall scheme of coal mine driving robot system is designed,and the basic mechanism,working principle and cooperation mechanism of driving robot,advanced supporting robot and drilling anchor robot are put forward,(2)A new type of automatic drilling and anchoring unit is put forward and its working principle is given.The unit has the functions of automatic drilling and anchoring,such as changing drill,drilling and installing bolt.(3)The 3D solid model of each component of the automatic anchor anchor unit is imported into the finite element analysis software ANSYS,and its static simulation model is established.The strength check,structural optimization analysis,modal analysis and fatigue strength analysis are carried out.(4)The key parts of the automatic drilling anchor unit are designed.The SolidWorks software is used to build the 3d solid model of anchor drilling robot and automatic anchor drilling unit.(5)The kinematics and dynamics analysis of the automatic drilling and anchor unit was carried out,and the three-dimensional solid model of the automatic dnrilling and anchor unit was imported into the kinematics analysis software ADAMS,which was simplified,constrained and driven.The kinematics and dynamics simulation model was established,and the simulation parameter curve was obtained and analyzed.The simulation results show that the mechanism design of the automatic drilling anchor unit is reasonable and the function is perfect.
