[0019] Ductile iron pipes, as a high-performance piping material, are widely used in water supply, fire protection, sewage, and gas transmission pipeline projects due to their excellent mechanical properties, corrosion resistance, ease of construction, and economic cost. Especially in urban water supply systems, ductile iron pipes have become one of the mainstream pipe materials. However, the installation of ductile iron pipes, particularly the alignment work, has always been a crucial aspect of pipeline construction.

[0020] Characteristics and Applications of Ductile Iron Pipes: Ductile iron pipes are pipes produced using centrifugal casting technology with ductile iron as the material. Their unique physical and chemical properties, such as high strength, high toughness, good ductility, and excellent corrosion resistance, make them outstanding in many applications. Compared with traditional pipes such as cement pipes and iron pipes, ductile iron pipes have higher reliability and service life. In water supply pipeline projects, ductile iron pipes have become an ideal alternative to traditional pipe materials. The application range of ductile iron pipes is wide, not only in urban water supply systems but also in water supply and gas transmission in industrial and mining enterprises. Their excellent performance and broad application prospects have led to continuous improvement and advancement in the production and construction technology of ductile iron pipes.

[0021] The Importance of Pipeline Alignment Equipment in Pipeline Construction: Alignment equipment is one of the key pieces of equipment in pipeline construction, primarily used for pipe alignment operations. Alignment is a crucial step in pipeline construction, and its quality directly affects the stability and safety of the pipeline system. The quality of the alignment equipment directly impacts the efficiency and quality of the alignment operation. During the installation of ductile iron pipes, alignment equipment needs to meet several requirements. First, the equipment must possess sufficient strength and rigidity to ensure no damage to the pipeline during the alignment process. Second, it needs precise alignment capabilities to ensure accurate pipe alignment. Furthermore, the equipment must be easy to operate and maintain to improve construction efficiency.

[0022] Analysis of Existing Pipeline Alignment Equipment Technology: With the widespread application of ductile iron pipes in pipeline engineering, the technology of pipeline alignment equipment has also been continuously developed. Currently, there are various types of alignment equipment on the market, each with different technical characteristics. The following is a detailed analysis of existing alignment equipment technology: Manual alignment equipment is one of the earliest types of alignment equipment. It has a simple structure and is easy to operate, but its alignment accuracy and efficiency are relatively low. Manual alignment equipment mainly relies on the skills and experience of the operator, and repeated adjustments are required during the alignment process to ensure the alignment accuracy of the pipeline. The advantages of manual alignment equipment are low cost and ease of maintenance. However, with the continuous expansion of pipeline engineering scale and the continuous improvement of construction requirements, manual alignment equipment has gradually become unable to meet construction needs. Mechanical alignment equipment was developed based on manual alignment equipment. It realizes pipeline alignment operations through mechanical transmission devices, improving alignment accuracy and efficiency. Mechanical alignment equipment typically includes clamping mechanisms, centering mechanisms, and adjusting mechanisms. The clamping mechanism is used to clamp the pipeline, ensuring that the pipeline does not move during the alignment process. The centering mechanism is used to center the pipeline, ensuring alignment accuracy. The adjustment mechanism is used to adjust the position and angle of the pipeline to adapt to different construction needs. Mechanical alignment equipment has the advantages of high alignment accuracy and efficiency, and a certain degree of automation. However, its structure is relatively complex, and maintenance costs are high. Furthermore, the application of mechanical alignment equipment in large-scale pipeline projects is somewhat limited. Hydraulic alignment equipment is one of the most widely used alignment methods. It achieves pipeline alignment through a hydraulic system, offering advantages such as high alignment accuracy, high efficiency, and ease of operation. Hydraulic alignment equipment typically includes a hydraulic cylinder, clamping mechanism, centering mechanism, and control system. The hydraulic cylinder is the core component of the hydraulic alignment equipment, providing the power required for the alignment operation. The clamping mechanism holds the pipeline, ensuring it does not move during the alignment process. The centering mechanism achieves the alignment function, ensuring alignment accuracy. The control system controls the operation of the hydraulic system, achieving automated control of the alignment operation. The advantages of hydraulic alignment equipment are high alignment accuracy, high efficiency, ease of operation, and ease of maintenance. However, its cost is relatively high, and it requires a high degree of stability and reliability from the hydraulic system. With the continuous development of intelligent technology, intelligent alignment equipment is gradually emerging. Intelligent alignment equipment integrates sensors, controllers, and actuators to achieve automated control and intelligent management of alignment operations. It can monitor various parameters during the alignment process in real time, such as pipeline position and alignment accuracy, and make adjustments and optimizations based on actual conditions. The advantages of intelligent alignment equipment are high alignment accuracy, high efficiency, simple operation, and easy maintenance. Furthermore, it also has intelligent management and remote monitoring functions, enabling full monitoring and management of the alignment operation. However, intelligent alignment equipment is costly and requires highly skilled technicians.

[0023] With the continuous expansion of pipeline engineering scale and the increasing demands of construction, alignment equipment technology will exhibit the following development trends: Future alignment equipment will place greater emphasis on increased automation. By integrating advanced sensors, controllers, and actuators, fully automated control and intelligent management of alignment operations will be achieved. This will help improve the efficiency and accuracy of alignment operations and reduce construction costs. The level of intelligence will become an important direction for the development of alignment equipment technology. By integrating advanced technologies such as artificial intelligence and big data, intelligent decision-making and optimization of alignment operations will be achieved. This will help improve the quality and safety of alignment operations and reduce construction risks. Future alignment equipment will place greater emphasis on multi-functional integration. By integrating multiple functional modules, such as clamping mechanisms, centering mechanisms, and adjustment mechanisms, one-stop services for alignment operations will be achieved. This will help improve construction efficiency and quality, and reduce construction and maintenance costs. With the increasing awareness of environmental protection, the research and development of energy-saving and environmentally friendly alignment equipment will become an important direction. By adopting new materials and optimizing structural design, energy consumption and emissions of alignment equipment will be reduced. At the same time, emphasis will be placed on the recyclability and reusability of the equipment to achieve resource recycling.

[0024] Matching equipment for ductile iron water pipelines is one of the key pieces of equipment in pipeline construction. With the continuous expansion of pipeline projects and the increasing demands of construction, matching equipment technology will continue to be improved and upgraded. Future matching equipment will place greater emphasis on automation, intelligence, multi-functional integration, and energy-saving and environmentally friendly development. This will help improve the efficiency and accuracy of matching operations, reduce construction and maintenance costs, and promote the progress and development of pipeline construction technology. At the same time, we should also recognize that the development of matching equipment technology still faces many challenges. These include the rapid pace of technological updates and iterations, requiring continuous investment in research and development and innovation; diversified market demands, necessitating the development of more adaptable matching equipment for different fields and scenarios; and increasingly stringent environmental regulations, requiring a focus on the energy-saving and environmentally friendly performance of the equipment. Therefore, in future development, we need to continuously strengthen technological research and development and innovation to improve the performance and adaptability of matching equipment to meet the ever-changing market demands and construction requirements.

[0028] This invention is mainly used for the alignment of ductile iron water pipelines. The main body of the equipment is a sleeve 1, inside which an alignment mechanism and a clamping assembly are installed.

One end of the connecting shaft 17 is rotatably connected to the inner wall of the housing 2, and the other end is fixedly connected to the output shaft of a motor 15. The motor 15 drives the connecting shaft 17 to rotate, which in turn drives the first transmission wheel 16, the belt 18, and the second transmission wheel 19 to rotate, causing roller 3 to rotate. By driving roller 3 to rotate via the motor 15, the conveying and centering operations of the pipeline are automated, improving operational efficiency. The belt 18 transmission structure is simple, reliable, and can stably transmit power.

[0031] The design is further optimized by fixing a support plate 14 to the inner wall of the housing 2, and fixing the motor 15 to the support plate 14.
