Daily maintenance of drilling rigs

1, Regular inspection items for drilling rigs
1. Inspect the main structural condition of the drilling rig, structural connection bolts, structural connection pins, welding seams of each structural component, hanging basket structure, and safety protection status. Especially before entering the site for use, qualified units should be invited to test its safety performance, and only after passing the inspection can it be used;
2. Regularly inspect the condition of various power heads, working cylinders, drill bits and drill rods;
3. Regularly inspect the anti wire rope detachment device on the drum of the hoist, as well as the height of the edges on both sides, the condition of the drum wall, and the number of turns of the wire rope tail on the drum. Especially, the condition of the brake port should be inspected as a key item at any time;
4. The inspection of electrical systems mainly includes the installation of dedicated electrical boxes and short-circuit and leakage protection devices, emergency power off switches, shock absorption devices for electrical boxes, fixation of cables on working devices, lighting circuits, and grounding wires strictly prohibited from being used as current carrying neutral wires;
2, Items that drilling rigs should be inspected at any time
1. Inspect the consolidation condition of the wire rope end;
The content of wire rope inspection includes: the number of safety circles of the wire rope, the selection, installation, lubrication of the wire rope, inspection of defects in the wire rope, such as the diameter and wear of the wire rope, and the number of broken wires in the wire rope;
2. Inspect the pulley system of the drilling rig at any time, mainly focusing on the condition of the pulley body and the anti jump rope device of the transition pulley;
3. Inspect the walking system of the drilling rig at any time, with the main inspection items including: the condition of the pile driving machine's pipe, clamp plate and hook pipe system, and the laying of sleepers;
3, Keep a good record of drilling rig maintenance and upkeep, and provide detailed records of replacement parts to ensure that they are used within their validity period or to keep track of the next replacement time at any time;
4, If any faults are found in the drilling rig, the operation should be stopped immediately and it should not be used until the faults are eliminated.
