[Abstract]:In order to improve the drilling efficiency of the bolt recovery device and realize lightweight, the helical drill pipe of the bolt recovery device is taken as the research object. The inner and outer diameter of the drill pipe, the thickness of the blade, the pitch of the screw, the spiral rising angle, and the rotational speed are taken as the research object. The optimum parameters are the number of heads and the height of the blade. The optimum targets are the highest conveying efficiency of drill pipe, the lightest weight and the highest secondary breakage rate. The particle swarm optimization algorithm is used to optimize the parameters of drill pipe structure. The results show that the drilling efficiency of the bolt recovery unit is increased by 31.4, the weight is reduced by 12.7, the secondary crushing rate is increased by 48.7, the recovery efficiency of the anchor rod is improved, and the wear resistance and strength of the screw drill pipe are enhanced.
