Floor sleeper for shield tunnel rail transport vehicle
The invention relates to a floor sleeper for a shield tunnel rail transport vehicle, which is characterized in that a three-section assembly spliced structure is adopted, a hinged support with adjustable height is arranged in the middle, rocker levers on two sides are connected with the middle hinged support through pin shafts, and after the rocker levers are in contact with a tunnel segment and are solidly seated, the horizontal consistency of a rail tread is ensured through the height adjustment of the middle hinged support. The integral one-piece sleeper is changed into a three-section hinged structure, arc-shaped surface contact of tunnel segments is changed into linear three-point contact, the applicability of the sleeper is greatly improved, and the cost performance of the sleeper is higher.
本发明涉及一种盾构隧道有轨运输车用落地轨枕，采用三段组件拼装式结构，中间布置高度可调节的铰座，两边的摇臂杆通过销轴与中间铰座相连接，所述摇臂杆与隧道管片接触座实后，通过中间铰座的高度调整，保证轨道踏面的水平一致。本发明通过将整体一根式轨枕改为三段铰接式结构，改变隧道管片弧形面接触为线型的三点接触，大大提升了轨枕的适用性，使其的性价比更高。
