Novel portable independent suspended railway sleeper for subsequent trolley matched with shield tunneling machine
The invention discloses a novel portable independent suspended railway sleeper for a subsequent trolley matched with a shield tunneling machine. The railway sleeper is characterized by comprising an arc-shaped steel plate, wherein the arc-shaped steel plate is clung to the inner surface of a shield segment; an upper limiting lug plate and a lower limiting lug plate are arranged at the two ends of the arc-shaped steel plate respectively, are matched with a bent bolt hand hole for circumferential weld connection of segments, and are in demountable connection with a nut on a bent bolt head for the circumferential weld connection of the segments; vertical steel plates are arranged on the arc-shaped steel plate; a horizontal steel plate for supporting steel rails is arranged at the upper ends of the vertical steel plates. The railway sleeper has the advantages that the structure is simple; the consumption of steel is reduced; the weight of the railway sleeper is effectively reduced; the arc-shaped steel plate is clung to the shield segment and is fixed by the limiting lug plates at the two ends of the portable railway sleeper, and workers work in an annular tunnel, so that the carrying safety of the workers, the production safety of the workers, and the walking safety of the workers are improved; the occurrence rate of safety accidents is reduced; not only is the railway sleeper convenient to demount and transport, but also the shield trolley walks stably and reliably, and is high in safety.
