As the core equipment of infrastructure construction, the daily maintenance of rotary drilling rig is the key to extending the service life of the equipment, reducing the failure rate, and ensuring the continuity of construction. Compared to maintenance and repair after a malfunction, scientific and standardized daily maintenance can not only reduce equipment wear and tear, lower operation and maintenance costs, but also avoid mid construction downtime and improve overall construction efficiency. Especially for equipment after complex geological operations such as gravel and hard rock, maintenance is of utmost importance.
Daily maintenance should follow the principle of "prevention first, comprehensive inspection, and timely disposal", focus on core components, take into account detailed maintenance, without the need for complex processes, and focus on implementing the following key points. Firstly, it is the maintenance of the power system. Regularly check the levels and purity of engine oil, coolant, and fuel, clean the air filter and fuel filter to avoid impurities entering the system, which may cause insufficient power or component wear. Especially after high-intensity operations in hard rock and gravel geology, it is necessary to promptly check the engine operating conditions and identify hidden dangers such as overheating and abnormal noise.
Next is the maintenance of drilling tools and drill rods, which are the core operating components of rotary drilling rigs and also the areas with severe wear and tear. Before and after homework, it is necessary to check the tightness of the connecting parts of the drill pipe, investigate problems such as bending of the drill pipe and cracking of the weld seam, regularly apply lubricating grease, and reduce wear at the connection points; For drilling buckets with severe wear and tear after pebble geological operations, timely check the wear of alloy teeth and drilling bucket walls, replace damaged parts, clean up residual debris inside the drilling bucket, and avoid corrosion; After hard rock work, it is necessary to focus on checking the wear of the cutter teeth and loose bearings of the rolling cutter drill bit, and promptly repair or replace them to prevent drill bit failure during rock breaking, which may cause stuck or buried drilling.
The maintenance of hydraulic and electrical systems cannot be ignored. Regularly check the sealing of hydraulic pipelines, identify oil leakage and seepage issues, replace aging pipelines and seals in a timely manner, keep hydraulic oil clean, regularly replace hydraulic oil and filter elements, and avoid hydraulic system blockage or insufficient pressure; The electrical system needs to check the firmness of the circuit connections, clean the dust on the surface of electrical components, investigate the working status of sensors, controllers and other components, and avoid short circuits and component failures that may affect the normal operation of the equipment.
Finally, there is the basic maintenance and post operation maintenance of the entire machine. After the daily homework is completed, clean the soil and debris on the surface of the whole machine to prevent mud and sand from entering the gaps of the equipment and causing component rust; Regularly check the tightness of the tracks and tire pressure (for wheeled models), check the tightness of the chassis bolts, and ensure stable equipment movement; Flexibly adjust the maintenance focus for equipment after different geological operations, such as increasing the inspection frequency of drilling tools and power systems after pebble and hard rock operations, timely handling minor wear and hidden dangers, and achieving "no accumulation of small problems and no occurrence of major failures".
The long-term stable operation of rotary drilling rigs cannot be achieved without regular and meticulous maintenance. Daily maintenance does not require excessive investment, but can effectively extend the service life of equipment, reduce failure rates, especially suitable for equipment maintenance needs after complex geological operations. It can not only reduce operation and maintenance expenses, but also ensure smooth construction progress, maximize equipment value, and provide support for infrastructure construction.
