The invention discloses a combined crosswind shielding device for a high-speed railway bridge, and relates to the technical field of high-speed railway bridge auxiliary equipment, a plurality of air ducts are arranged in a baffle body from top to bottom, a plurality of through holes are fixedly formed in the front side wall and the rear side wall of the baffle body in a matrix mode, and the through holes in the front side and the rear side are communicated with the air ducts in the corresponding positions; the upper end of the first reel rotationally penetrates through the top face of the first mounting groove through a bearing and then extends to the upper side of the baffle body. One side edge of the curtain is wound and fixed to the outer side wall of the first reel, and the other side edge of the curtain penetrates through an opening in the right side of the first mounting groove and then extends to the outer side of the baffle body. A hook is fixedly connected to the other end of the first steel wire rope and arranged on the hanging ring in a hooking mode. A spliced structure is adopted for installation, the wind barrier is convenient to adapt to bridges with different lengths. Meanwhile, a retractable shielding structure is adopted, the fatigue problem of the wind barrier is solved, and when a train does not run, the wind load borne by the bridge is reduced.
一种高速铁路桥梁组合侧风遮挡器，本发明涉及高铁路桥辅助设备技术领域，挡板本体的内部从上到下设置有数个风道，挡板本体的前后两侧壁上矩阵式固定设置有数个通孔，且前后两侧的通孔与相对应位置上的风道相贯通设置；一号卷轴的上端通过轴承旋转穿过一号安装槽的顶面后，伸设在挡板本体的上侧；幕布的一侧边绕设并固定在一号卷轴的外侧壁上，幕布的另一侧边穿过一号安装槽右侧的开口后，伸设在挡板本体的外侧；一号钢丝绳的另一端上固定连接有挂钩，挂钩勾设在挂环上；采用的是拼接式的结构进行安装，方便适应不同长度的桥梁，同时，采用的是可收缩的遮挡式结构，减少了风屏障的疲劳问题，在列车不行使时，减少桥梁承受的风荷载。
