Large-span normal-conducting high-speed magnetic levitation bridge parting and rail surface smoothness improving structure
The invention discloses a gear-driven large-span normal-conducting high-speed magnetic levitation bridge parting and rail surface smoothness improving structure which comprises a parting bearing beam, a span beam seam beam unit and N-1 parting beam units. The parting beam units are slidably supported on the upper surface of the parting bearing beam and one side of the span beam seam beam unit to form N parting beam seams; a push-pull rod is longitudinally arranged on the parting bearing beam in a sliding mode, one end of the push-pull rod extends out to be hinged to the beam end of the first bridge, racks are arranged on the opposite faces of the push-pull rod and the N-1 parting beam units, and N-1 gear sets are correspondingly arranged between the upper rack and the lower rack. A gear mechanical device is adopted for driving to automatically convert a large expansion amount into a plurality of equal small expansion amounts, so that the beam seam gap variation is reduced, and the irregularity of a beam end corner bulge is reduced, which plays a very important role in improving the running of a normal-conducting high-speed maglev train.
本发明公开了一种齿轮驱动的大跨度常导高速磁浮桥梁分缝及改善轨面平顺性的构造，其中，包括：分缝承载梁，跨梁缝梁单元，N‑1个分缝梁单元，滑动支撑在分缝承载梁的上表面、跨梁缝梁单元的一侧，形成N个分梁缝；推拉杆，纵向滑动设置于分缝承载梁上，一端伸出铰接于第一桥梁的梁端，推拉杆与N‑1个分缝梁单元的相对面均设有齿条，上下齿条之间对应设有N‑1个齿轮组；本发明采用齿轮机械装置驱动自动实现将大伸缩量转变为若干个相等的小伸缩量，减小了梁缝间隙变化量、减小了梁端转角突起不平顺量对改善常导高速磁浮列车的行驶具有非常重要的作用。
