Track layer portal frame structure capable of changing span during advancing
The invention discloses a track layer portal frame structure capable of changing span during advancing, which comprises a main beam, swinging span changing mechanisms, upright posts and walking beams are arranged at four corners of the main beam, one end of each swinging span changing mechanism is hinged with the main beam, and the other end of each swinging span changing mechanism is hinged with the upper part of each upright post; the walking beam is arranged on the lower portion of the stand column. The swing span-changing mechanism comprises a swing rotating seat and a span-changing oil cylinder, one end of the swing rotating seat is hinged to the side edge, parallel to the advancing direction of the track layer, of the main beam, and the other end of the swing rotating seat is hinged to the upper portion of the stand column. The two ends of the variable-span oil cylinder are arranged on the side edges, perpendicular to the advancing direction of the track layer, of the swing rotating base and the main beam correspondingly, and the distance between the stand columns on the two sides of the main beam in the advancing direction of the track layer is adjusted through stretching and retracting of the variable-span oil cylinder. And a rotary span changing mode is adopted, so that complete machine transportation can be met, and the construction requirements of different spans can be met.
本发明公开了一种在行进中变跨的铺轨机门架结构，包括主梁，在主梁的四角处均设有摆动变跨机构、立柱、以及行走梁，摆动变跨机构的一端与主梁铰接相连，摆动变跨机构的另一端和立柱的上部铰接相连；行走梁设在立柱的下部；摆动变跨机构包括摆动旋转座和变跨油缸，摆动旋转座的一端铰接在主梁与铺轨机行进方向平行的侧边上，摆动旋转座的另一端铰接在立柱的上部；变跨油缸的两端分别设在摆动旋转座和主梁与铺轨机行进方向垂直的侧边上，通过变跨油缸的伸缩实现对主梁沿铺轨机行进方向两侧立柱间距的调节。采用旋转变跨的方式，既能够保证满足整机运输，又可以适应不同跨度的施工需求。
