Abstract
Reverse circulation drilling technology is widely used in geological exploration due to its high drilling efficiency, accuracy, and safety. The machine frame is the core component of a reverse circulation drilling machine, which provides support and guidance for the entire mechanism. In this paper, we will introduce the design process and methodology of a three-dimensional (3D) machine frame based on ProE software for a reverse circulation drilling machine. The design process and methodology are discussed in detail, including the modeling of each component, assembly of the machine frame, and validation of the design using finite element analysis (FEA). Finally, the design meets the requirements of structure deformation and stress.

Introduction
Reverse circulation drilling is an efficient drilling technology for geological exploration, mineral exploration, and water conservancy projects. It has the advantages of high drilling speed, good drilling quality, small drilling diameter, and low blind hole rate. The machine frame is the main support structure of the reverse circulation drilling machine. The frame provides support for the main components of the drilling machine, such as the power system, hydraulic system, winch, and rod changing system. The machine frame also supports the drilling tool string and guides it to the target formation. An optimal machine frame design can effectively improve drilling efficiency, accuracy, and safety.
In this paper, a reverse circulation drilling machine frame is designed using ProE, which is one of the most widely used 3D modeling software in the industry. The design process involves modeling each component, assembling the components, and validating the design using finite element analysis (FEA). The machine frame structure is optimized to meet the requirements of deformation and stress. The final design provides a reference for the design and manufacture of reverse circulation drilling machines.
Design Process
The design process includes the following steps: collection of design requirements, modeling of each component, assembly of components, and finite element analysis.
1. Collection of design requirements
Based on the technical requirements of reverse circulation drilling machines, the design requirements of the machine frame are summarized, including the drilling depth, drilling diameter, drilling speed, lifting capacity, supporting power, and steering performance.
2. Modeling of each component
The machine frame is composed of several components, including the main frame, the mast, the drilling tool string, and the control system. Each component is designed separately in ProE, and the design specifications are verified and refined. For example, the size and position of mounting holes, the clearance between components, the thickness of the frame, and the shape of the mast.
The modeling process involves creating a 3D model of each component, using the appropriate tools and features in ProE to create complex geometric shapes, and verifying each component's geometrical and functional requirements.
3. Assembly of components
The assembly process involves combining each component into a complete machine frame system. The assembly is checked for any interference or inconsistency among the components. The crucial assembly points are focused on, such as the mast mounting, the drilling string connection, and the control system installation.
4. Finite element analysis
The machine frame's final design is validated using finite element analysis to ensure its structural integrity and performance under load. The FEA analysis includes calculation of the deformation, stress, and safety factor of the machine frame.
Results and Discussion
The final design of the machine frame meets the requirements for drilling depth, diameter, speed, lifting capacity, and supporting power. The machine frame is optimized to reduce weight, minimize deformation, and increase stability under load.
The FEA analysis concludes that the stress and deformation of the machine frame in normal operation are within the range of safety. The maximum stress and deformation are concentrated on the mast mounting, which is reinforced by additional support structures. The safety factor of the machine frame is higher than the standard requirement, indicating a high safety level.
Conclusion
In conclusion, the design process and methodology of the reverse circulation drilling machine frame based on ProE software are described in detail in this paper. The main components are modeled and assembled to create a comprehensive 3D design of the machine frame. Using finite element analysis, the stress and deformation of the machine frame are calculated to verify its structural integrity and safety. The final design satisfies the requirements and provides a reference for the design and manufacture of reverse circulation drilling machines.
