Carbon Steel Structural Parts Of Shield Machine Frame And Traveling Mechanism

As the key parts of the shield machine, the carbon steel structural parts of the shield machine frame and traveling mechanism play a vital role in the stable operation of the shield machine. Its main body is made of high-quality carbon steel material. Carbon steel has good comprehensive mechanical properties and high strength, and can withstand the huge load generated by the shield machine in a complex construction environment. At the same time, a certain toughness enables it to effectively resist the impact and vibration during construction, reducing the risk of structural parts being damaged due to force. ​
In terms of structural design, the frame part usually adopts a frame structural parts. The crossbeams and longitudinal beams are reasonably arranged and firmly connected through welding technology to form a stable bearing platform, providing a reliable installation foundation for other equipment of the shield machine. This structural design ensures that the frame can still maintain good rigidity and stability when it is subjected to forces in different directions, avoiding deformation that affects the normal operation of the shield machine. ​
The carbon steel structural parts of the traveling mechanism are also carefully designed. The brackets and other parts of the traveling wheel are made of special carbon steel profiles. After precise processing and assembly, they are tightly and flexibly connected to the frame. The size, material and installation method of the traveling wheel are optimized to ensure stable walking on the bottom of the tunnel and adapt to different geological conditions. In addition, the steel structural parts of the traveling mechanism also takes into account factors such as lubrication and sealing to reduce wear and extend service life, ensuring that the traveling mechanism can operate reliably during long-term, high-intensity construction and drive the shield machine to advance smoothly.
