Abstract:

There are problems exsiting in a drilling process of hydraulic rock drill,for example,the front end cover becomes loose,rotary pressure can not be tested,impact piston strains and the drill does not impact.In order to improve drilling efficiency of imported drilling jumbo in downhole production and reduce consumption of materials and spare parts,fixed bolts hole is applied in drilling machine end cover, and fixed boles are also used to improve fastening condition and relax.The drive shaft of old trackless equipment is reformed to meet the pressure test requirements,and it can judge the hydraulic system bug of drilling machine quickly,raising the maintenance efficiency;Rebuilding the original balance tank on impact piston and seting symmetrical oil pan on the cylindrical surface helps completing the shock cycle,and meeting the needs of drilling.Technical innovation of rock drilling creats a good condition for mine production,improves serviceability rate,utilization rate and production efficiency,and the failure rate is also decreased.
