ã€China Deep Hole Rig Trading Network】
First, the rig regularly check the project [2]
1. Inspect the main structural condition of the drilling rig, bolts of structural connections, connection pins of structural parts, welds of various structural parts, structure of the structural baskets, and safety protection conditions. In particular, prior to entering the field, qualified personnel should The safety performance is tested and can be used only after passing the test;
2. Regularly check the condition of various power heads, working oil cylinders and drill stems;
3. Regularly check the hoist rope anti-roping shedding device and the height of both sides of the hoisting machine, the condition of the drum wall, and the number of weeks on the drum at the end of the wire rope. In particular, check the condition of the brake opening at any time to check key items. ;
4. Inspection of electrical system: The main inspection items are: special box setting and short circuit protection and leakage protection device, emergency power off switch, electric box damping device, fixed cable on working device, lighting circuit, grounding line Flow zero line;
Second, the rig should be checked at any time the project 1, the wire rope end of the consolidation of the situation to check;
The contents of the inspection of the steel wire rope are: number of safety ropes for steel wire ropes, selection, installation and lubrication of steel wire ropes, defect inspection of steel wire ropes, such as wire rope diameter and wear condition, number of broken wire ropes, etc.;
2. Check the pulley system of the drilling rig at any time. The main inspection items are: pulley body condition, transition pulley anti-skipping device;
3. Check the running system of the drilling rig at any time. The main inspection items are: the situation of pile pipe, card board and hooking system, and sleeper laying;
Third, do a good job rig maintenance records, the replacement of spare parts should have a detailed record to ensure that spare parts are used within the validity period, or to keep abreast of the time of the next replacement;
Fourth, check out the rig is faulty, should immediately stop the operation, before the failure has not been eliminated shall not be used.
