Beam end steel rail telescopic device and telescopic method for movable bridge
The invention relates to a beam end steel rail telescopic device and a telescopic method for a movable bridge, which can enable a bridge deck to rotate by 90 degrees to be parallel to a river, enable ships in the river to pass through smoothly, realize rail communication when the bridge deck is communicated, and meet the driving requirement. The device comprises a fixed end and a telescopic end, wherein the fixed end and the telescopic end are located on two bridge deck slabs of a bridge respectively, a large-span gap is formed in the middle of each bridge deck slab, the bridge deck slabs can be opened in a rotating mode, and the navigation requirement of riverway ships is met; and the telescopic end comprises a steel rail expansion piece and a mechanical device, and after the two bridge deck slabs rotate to be in a connected state, stock rails of the steel rail expansion piece are pulled through the mechanical device, so that the stock rails are driven by external force to move in a telescopic mode and are in butt joint with a line rail at the fixed end to be locked, and it is ensured that a train passes.
本发明涉及一种既可以使桥面板旋转90°，与河流平行，河流中船只可顺利通过，又可以使桥面连通时，实现轨道连通，满足行车要求的用于开启桥的梁端钢轨伸缩装置及伸缩方法，由固定端和伸缩端组成，固定端和伸缩端分别位于桥梁的两块桥面板上，桥面板中间设置大跨度间隙，桥面板可实现旋转开启，满足河道船只通航需求；伸缩端包括钢轨伸缩器、机械装置，当两桥面板旋转至接通状态后，通过机械装置牵引拉动钢轨伸缩器的基本轨，使基本轨在外力驱动下伸缩移动，与固定端线路轨道实现对接锁止，确保列车通过。
