291 results about "Track gauge" patented technology

In rail transport, track gauge or track gage is the spacing of the rails on a railway track and is measured between the inner faces of the load-bearing rails. All vehicles on a rail network must have running gear that is compatible with the track gauge, and in the earliest days of railways the selection of a proposed railway's gauge was a key issue. As the dominant parameter determining interoperability, it is still frequently used as a descriptor of a route or network.

A method for muck removal and transportation in a variable cross-section tunnel with four anchor rails and three tracks.

This invention discloses a four-track, three-line method for muck removal and transportation in variable cross-section tunnel anchors. For tunnel anchors with steep axial inclination angles, four shared tracks are used to form three lines: one is a large-gauge integrated equipment and material transport line, and two are small-gauge circulating muck removal lines. First, the integrated equipment and material transport line, driven by a power mechanism, pulls a transport platform to transport the relevant equipment and materials for excavation at the tunnel face. Near the tunnel face, the excavation equipment is unloaded for excavation. The excavated muck is then circulated and removed using the dual-circulation muck removal lines, driven by a power mechanism and circulated by mine cars. This allows excavation and muck removal to be carried out simultaneously, significantly improving muck removal efficiency. After excavation, the transport platform returns to the outside of the tunnel anchor to load support materials before returning to the tunnel face. The entire transportation process involves fewer transfer steps, improving construction efficiency and reducing environmental pollution. The transport platform and mine cars are driven by power mechanisms and run along the tracks, resulting in a higher safety factor.
