Although the information about rotary drilling rigs, which are widely used in the construction industry, has been briefly described, it is still necessary to explore its application scenarios and maintenance in depth. As an important tool in modern building construction, rotary drilling rigs play a pivotal role in improving project efficiency and quality. However, in view of its long daily operation, it is particularly important to carry out effective maintenance and repair to ensure the continuous and stable operation of the equipment.
In the maintenance process of rotary drilling rigs, the primary concern is the lubrication and wear of its rotary slewing support, drill pipe slewing support, as well as key components such as the shafts and bushings of each ministry, the power box runway, the drill pipe runway, and the rope lifter. Lack of sufficient grease or wear of these parts will directly affect the normal operation of the equipment. Therefore, regular inspection and replenishment of grease, timely detection and treatment of wear and tear problems, is the most important maintenance work. In addition, the fastening of the screws of the whole vehicle should not be neglected, especially the screws in key positions such as the fixed engine bolts, slewing bearing bolts, swing head bolts, fixed drilling rod bolts and travelling reducer bolts, which need to be checked regularly to see if they are loosening or falling off, so as to ensure the overall stability of the equipment.
In addition to the above checks, the maintenance of the wire rope, circuit relay, oil pipe and sealing ring of the rotary drilling rig is also crucial. Wire ropes that are rusty or broken should be replaced immediately to prevent safety accidents or construction delays. Circuit relays should be checked regularly for deterioration and spare parts should be prepared in advance in case of emergency. The broken condition of oil pipes and seals should also be checked at any time, and spare parts should be prepared for emergencies. In addition, the rotational flexibility of the drill pipe rope lifter bearing is also an important part of the maintenance work, and should be replaced as soon as damage is found.
In summary, the maintenance work of rotary drilling rigs involves many aspects and needs to be carried out comprehensively and carefully. Through regular inspection and maintenance, it can not only prolong the service life of the equipment, but also ensure its safety and stability in the construction process. Therefore, we should attach great importance to the maintenance of rotary drilling rigs, and constantly improve the level of maintenance to contribute to the sustainable development of the construction industry.
