Structural Design and Calibration of Hydraulic Drilling Rig for Coal Mine Geology
In order to solve the efficiency and safety problems of manual rod loading and unloading,based on the original hydraulic drilling rig,three automatic rod loading and unloading devices were discussed and the implementation plan was decided.Based on this premise,the structure of the original hydraiilic drilling rig is improved so that the new structure can better serve the function of automatic rod loading and unloading,and then the important parts are calibrated to prevent safety accidents caused by excessive fatigue of the parts due to the change of force after the change of structure.
