Hongwei Li · Coal science and technology · 2010
In order to improve the reliability of the bolt drilling rig and to reduce the maintenance cost,the loading test device was applied to the loading test of the bolt drilling rig after the overhaul completed or before the factory outlet.The paper introduced the structure features and the main technical parameters of the loading test device and stated the compositions and the functions of the hydraulic control system and the electric control system applied in the loading test device.The test results showed that the loading test device could highly reduce the initial fault rate after the overhaul and after the equipment out from factory outlet and could improve the reliability of the equipment operation.Meanwhile,during the application of the equipment,the input of the production spare parts before the application of the equipment could be saved,the great labor force could be saved and the total usage efficiency of the equipment could be improved.The loading test device could be stable in operation and be easy for inspection.
