The rural foundation pile driver is a new type of construction equipment developed and innovated in China over the years. It integrates machinery, electricity, and hydraulics, boasting improved performance and advantages. Performance-wise, it offers high drilling efficiency, fast operational progress, and stable, reliable quality. From an advantages perspective, its main features include mechanization, high automation, strong environmental protection, multifunctionality, and great adaptability to different strata. It also represents the development direction of rural foundation pile drivers and has received high praise from construction departments. Most rural foundation pile drivers are used in large-scale construction projects such as highways, bridges, power plants, and deep-water docks, widely applied nationwide. Among its components, the drill rod is an indispensable part, with its structure receiving significant attention. The resistance of the drill rod directly determines the type of drill bit selected, while the shape of the drill tool also significantly affects drilling efficiency and adaptability to the strata. On the other hand, the design of the power configuration, hydraulic system, and support structure is also based on the structure and performance of the drill rod, making the entire system configuration more rational. To ensure the safe operation of the drilling rig, it is necessary to perform simulation and analysis on the static, modal, and fatigue strength.

The distance between the two sides of the special track chassis can be adjusted appropriately. During transportation, the two tracks can quickly contract, allowing adjustments and improvements to the chassis under certain construction conditions. In this scenario, the stability of the drilling rig is well-maintained. When the tracks extend on both sides of the chassis, several relatively classic conditions are significantly stressed. Strength and rigidity directly impact the stability of the drilling rig, which in turn affects the quality of the hole. Therefore, a chassis strength analysis is necessary to ensure the safe use of the drilling rig. Through analysis, we gain a preliminary understanding of the tension levels and chassis tension, identifying weak links and other parts of the chassis, which can also provide effective support for future optimization efforts.
