Stability Design Considerations for the Undercarriage and Traveling Mechanism of a Rotary Drilling Rig

    Rotary drilling rigs are often used in complex working conditions such as infrastructure, bridges, and mines. The chassis and walking mechanism serve as the "cornerstone" of the equipment, and their design rationality directly determines the equipment's adaptability, operational stability, and construction safety in complex terrains. Targeted design of chassis and walking mechanisms for complex terrains such as mountains, mud, karst, and coastal sand layers has become the core key to solving construction problems and improving operational efficiency.

    The core of adaptive design for complex terrain is to break through the terrain limitations of different working conditions and achieve flexible operation in all scenarios. Faced with steep terrain such as mountains and hills, the chassis adopts an adjustable leg design, which can quickly adjust the level of the machine body through hydraulic synchronization control, offset the influence of terrain slope, ensure the horizontal posture of the drilling rig during operation, and avoid construction deviation or equipment failure caused by machine body inclination. For easy to sink terrain such as mud and soft soil, the walking mechanism adopts a wide track design to increase the grounding area and reduce the grounding pressure, effectively preventing equipment from sinking. At the same time, anti slip patterns are added to the track surface to enhance the grip of muddy roads and ensure smooth movement of equipment. In complex geological areas such as karst and pebble layers, the chassis adopts a high-strength frame structure, combined with impact buffering devices, to alleviate vibration transmission during drilling operations, avoid frame deformation, and adapt to the high-intensity operation requirements in complex geological conditions.

    Stability design is the core guarantee for safety and construction accuracy in complex terrain operations, running through the entire dimensions of structure, control, and protection. Structurally, the chassis adopts a box type frame structure and is made of high-strength steel that is integrally formed to enhance overall rigidity and torsional resistance, reduce deformation of the machine body during operation, and provide stable support for drilling operations; The optimized transmission system of the walking mechanism adopts a planetary gear transmission design, which combines the advantages of strong power and smooth operation, avoiding jamming and deviation during complex terrain movement, and ensuring the coordination between equipment movement and operation. In terms of control, an intelligent balance control system is introduced to monitor the body posture, leg force, and track tension in real time. Once tilting or uneven force occurs, timely warnings are issued and automatic adjustments are made to prevent safety risks. In terms of protection, dust-proof, waterproof, and anti-collision covers are added to key parts of the chassis and walking mechanism to adapt to harsh working environments such as mines and coastal areas, extend the service life of components, and ensure long-term stable operation of equipment.

    The adaptability and stability design of the chassis and walking mechanism are the core competitiveness of rotary drilling rigs in dealing with complex working conditions. As infrastructure projects extend to remote and complex areas, the requirements for equipment terrain adaptability and stability continue to increase. In the future, with the iteration of lightweight design and intelligent control technology, the chassis and walking mechanism will be further optimized for adaptability and stability, meeting the operational needs of diverse and complex terrains while improving construction efficiency and safety, providing solid support for efficient operation of rotary drilling rigs.
