Railway long-span bridge beam end telescopic sleeper lifting device
The invention discloses a railway long-span bridge beam end telescopic sleeper lifting device, which adopts a deck type telescopic sleeper lifting device structure, on the basis, a steel longitudinal beam is additionally arranged, and the steel longitudinal beam is positioned between two steel rails and fixed at the center position of a sleeper. The movable steel sleeper has the advantages that the vertical rigidity and the longitudinal traction point of the steel sleeper are increased, it is guaranteed that the movable steel sleeper moves evenly in the longitudinal direction, vertical stress deformation of the movable steel sleeper is reduced, the transition uniformity of the vertical rigidity of a rail is improved, safety and comfort are better guaranteed when a train passes through, and the maintenance workload in the operation stage is reduced.
本发明公开了一种铁路大跨度桥梁梁端伸缩抬枕装置，采用上承式伸缩抬枕装置结构，在此基础上，新增了一根钢纵梁，该钢纵梁位于两根钢轨中间，固定在轨枕正中位置。本发明的优点是：增加了钢枕垂向刚度和纵向牵引点，保证活动钢枕在纵向上均匀活动、减小其垂向的受力变形，提升轨道垂向刚度过渡均匀性，更好保障列车通过时的安全性和舒适性，并减少运营阶段的养护维修工作量。
