(b) operating protocol for the operation of the sub-crowding rig i, pre-work preparation 1. 1 checks whether the parts of the machine are in good condition and clean; 1. 2 checks whether the hydraulics, airline connections are correct and the contours are undamaged; 1. 3s checks whether the hydraulic fluids are in line with the marking line; 1. 4s checks whether the brakes, steering gears are flexible and operational; 1. 5s checks whether the rigs, drills, drill triggers, drill extensioners, etc. Are adequately prepared。
During working hours, 2. 1. Installation of drill poles, each of which will be fitted in order and in a strict order and direction, to ensure that the drills are strengthened and strengthened; 2. 2. Removal of shovels or directional head and installation of suitable drills; 2. 3. Installation of mouth poles and mouthboards, which will bind the extension pipelines; 2. 4. Opening of the hydraulic system switch, which will place the handle in the right middle position, and the petrol engine will pull up and drive; 2. 5. Hand handles to the left and drill under the main axis; hand handles to the right, with the main axis moving back and forth; 2. 6 control of the toyboard position, controlling movement in the left, back and back direction, adjusting the drilling position, depth, etc.; 2. 7 when the project progresses to a certain level, it will be necessary to remove water, stop drilling, pull back to a safe distance, close the engine, retake the drill, and conduct cleaning and drainage operations。
Operations 3. 1 the handle shall be placed in the centre; 3. 2 the handle shall be pulled to the middle to ensure safety when the engine is shut down; 3. 3 security measures shall be strengthened in the vicinity of high voltage wires to avoid hazards; 3. 4 in the operation, care shall be taken to protect all parts of the rig from impact or wear; 3. 5 in the event that the drilling depth exceeds the design depth, the controller shall be adjusted in a timely manner to stop the respiration of the valve to prevent the drilling pole from cracking, saturation and soil seepage。
Follow-up to the completion of work: 4. 1 closure of the petrol switch and the corresponding switches for gas, hydraulic components, water and electrical circuits; 4. 2 cleaning and maintenance of equipment, cleaning of miscellaneous items around the equipment and protection of equipment; 4. 3 cleaning of drills, tools and safekeeping for next use。
