Ballast track settlement self-adaptive track system
The invention provides a ballast track settlement self-adaptive track system which comprises a ballast bed, a self-adaptive sleeper, a steel rail and a steel rail fastener, the self-adaptive sleeper is arranged at the upper end of the ballast bed, and the steel rail is perpendicular to the axis of the self-adaptive sleeper through the steel rail fastener and is installed on the upper surface of the self-adaptive sleeper; the self-adaptive sleeper comprises a sleeper body and a self-adaptive device set, the self-adaptive device set is arranged on the lower surface of the sleeper body, the lowersurface of the self-adaptive device set makes contact with the upper surface of a ballast bed, and the self-adaptive device is used for increasing the height of the self-adaptive device through downward leakage of internal fluid particles due to gravitational potential energy, so that the self-adaptive device is closely attached to the sleeper to achieve supporting. The device can be used for a sleeper empty hanging section, and under the action of train cyclic loads, the support, the base and the fluid rigid particles jointly transmit the train loads to a ballast bed.
本发明提供的一种有砟轨道沉降自适应式轨道系统，包括道床、自适应轨枕、钢轨和钢轨扣件，自适应轨枕设置于道床上端，钢轨通过钢轨扣件垂直自适应轨枕轴线安装在自适应轨枕上表面；自适应轨枕包括轨枕本体和自适应装置组，自适应装置组设置于轨枕本体下表面，自适应装置组下表面与道床上表面接触，自适应装置用于通过内部流体颗粒因重力势能下漏提高自适应装置高度，使自适应装置与轨枕密贴，实现支撑。本装置可用于轨枕空吊区段，在列车循环荷载作用下，支座、底座、流体刚性颗粒共同将列车荷载传递至道床。
