Drilling rigs can sample underground deposits or be used to install underground production equipment, such as underground machines, instruments, pipelines, and shafts. So, how to maintain after daily use? Let's understand together.
1. Items for periodic inspection of drilling rigs
1. Check the main structural conditions of the rig, bolts of the structural connectors, connecting pins of the structural members, welds of the structural members, the structure of the gondola and safety protection status, especially before entering the field, please have qualified units Check the safety performance and use it after passing;
2. Regularly check the status of various power heads, working cylinders and drill rods;
3. Regularly check the anti-wire rope shedding device of the hoist and the height of the edges on both sides, the condition of the reel wall, and the number of weeks of the tail of the wire rope on the reel, especially the status of the brake port should be checked at any time as a key item ;
4. The inspection of the electrical system, the main inspection items are: special electrical box settings and short-circuit protection and leakage protection devices, emergency power-off switch, electrical box shock absorber, fixing of cables on working devices, lighting lines, grounding lines are strictly prohibited Current zero line, etc.;
Second, the items that the rig should check at any time
1. Check the consolidation of the rope end of the wire rope;
The content of the wire rope inspection is: the number of wire rope safety loops, the selection, installation and lubrication of the wire rope, and the defect inspection of the wire rope, such as the diameter and wear of the wire rope, the number of broken wires, etc.;
2. Check the pulley system of the drilling rig at any time, the main inspection items are: the status of the pulley body, the anti-skipping device of the transition pulley;
3. Check the walking system of the drilling rig at any time, the main inspection items are: the status of the pile pipe walking, chuck and hook pipe system, sleeper laying, etc.;
3. Make maintenance records of the drilling rig, and keep detailed records of the replacement parts to ensure that the parts are used within the validity period, or keep abreast of the time of the next replacement;
4. Check that the drilling rig is faulty, all operations should be stopped immediately, and it should not be used until the fault is not eliminated.
