From a performance perspective, guardrail pile drivers are highly efficient in drilling, fast in operation, and stable and reliable in quality. In terms of advantages, they are primarily characterized by a high degree of mechanization and automation, strong environmental friendliness, multiple functions, and strong adaptability to different strata. They also represent the development direction of rural foundation pile drivers and are highly valued by construction departments.

Pile drivers are mostly used in larger construction projects, such as highways, bridges, power plants, deep-water ports, and other pile foundation construction operations, with a wide range of applications nationwide. Among these, the drill rod is an indispensable component of rural foundation pile drivers. The structure of the drill rod is also a focus, as its strength directly determines the type of drill bit used. However, the form of the drilling tool also determines the drilling efficiency and adaptability to different strata to some extent. On the other hand, the design of the equipment's own power configuration, hydraulic system, support structure, etc., is also based on the structure and performance of the drill rod, making the overall system configuration more reasonable. To ensure the safe operation of the rotary drilling rig, it is necessary to perform simulation calculations and analyses on its static strength, modal properties, and fatigue strength.

The distance between the two sides of the specialized crawler chassis can be adjusted appropriately. During transportation, the two tracks will quickly retract, facilitating transport under certain construction conditions. The chassis is adjusted and improved, optimizing the stability of the drill rig. When the tracks on either side of the chassis are about to extend, several classic working conditions will experience severe stress. The strength and rigidity directly affect the stability of the drill rig, which can impact the quality of the holes. Therefore, it is necessary to analyze the strength of the chassis to ensure the safe use of the drill rig.
