The Progress Process of Rotary Drilling Rig Parts

As the core equipment for pile foundation construction, the efficient operation of rotary drilling RIGS cannot be achieved without the coordinated operation of various accessories. From the early simple structure to today's intelligent integration, every advancement of accessories has driven a leap in the performance of rotary drilling RIGS and witnessed the iterative development of pile foundation engineering technology.

1. Power system accessories: In the early days, diesel engines were mainly used, which had high fuel consumption and unstable power output. Now it has been upgraded to an electronically controlled high-pressure common rail engine, combined with turbocharging technology, with power increased by more than 30% and fuel consumption reduced by 15%, making it more capable of adapting to complex working conditions.

2. Drill tool accessories: The initial drill bucket was made of ordinary manganese steel, which was prone to wear and had low drilling efficiency. Now, high-strength wear-resistant alloys are adopted, and the cutting edge design is more in line with soil cutting mechanics. The service life is extended by 2 to 3 times, and the drilling speed of hard rock is significantly improved.

3. Hydraulic system accessories: Traditional hydraulic valve groups respond slowly and are prone to oil leakage problems. The new type of electro-hydraulic proportional control valve, in combination with wear-resistant sealing parts, has increased the response speed by 50%, reduced the failure rate by 60%, and significantly improved the operation accuracy.

4. Chassis walking accessories: In the early days, the material of the track plates was relatively soft and prone to slipping on muddy ground. Now, reinforced track plates are adopted, with optimized pattern design, reduced ground contact pressure, improved passability on complex terrains, and enhanced driving stability.

5. Intelligent control accessories: In the past, manual operation was relied upon, and the drilling parameters were all based on experience. Nowadays, by installing sensors and intelligent controllers, real-time monitoring of data such as rotational speed and torque can be achieved, and drilling parameters can be automatically adjusted to reduce human errors.

6. Lubrication and cooling accessories: Traditional lubrication systems require manual addition at regular intervals, resulting in poor cooling effects. Now it has been upgraded to an automatic centralized lubrication system, combined with a high-efficiency radiator, reducing mechanical wear and extending the continuous operation time of the equipment to over 8 hours.

The progress of rotary drilling rig parts is the result of the deep integration of materials science, intelligent manufacturing and engineering practice. From single-function optimization to system collaborative upgrade, the continuous improvement of accessory performance not only makes rotary drilling RIGS more efficient and durable, but also provides solid support for the expansion of pile foundation engineering into deeper and more complex geological conditions, driving the foundation construction industry to constantly reach new heights.
