Abstract: Addressing the technical bottlenecks in traditional jacking relay stations, such as low installation efficiency, high safety risks, poor equipment adaptability, and complicated procedures, this paper proposes a new relay station design based on a radially adaptive diamond telescopic structure combined with hydraulic cylinder hinged fixation technology. Through the collaborative mechanism of the axial pushing components and the radial diameter-changing components, this structure achieves rapid support and overall recovery under different pipe diameters, fundamentally avoiding the cumbersome process of repeated disassembly and assembly of cylinders in traditional relay stations. Studies show that the radial adjustment unit composed of a diamond telescopic framework, combined with the T-slot-rod guide limiting mechanism and the integrated design of built-in pushing components, can improve equipment adaptability and work efficiency.
