本发明公开了一种铁路接触网隧道内圆柱面自适应预埋槽道。它包括沿线路纵向方向镶嵌于隧道内壁的异形钢槽道和沿线路纵向方向间隔设置于异形钢槽道内的心形螺栓,所述异形钢槽道通过锚杆固定于隧道内壁上,所述心形螺栓通过卡榫安装于异形钢槽道内部,所述卡榫与异形钢槽道的侧壁齿槽配合,所述心形螺栓的头部与卡榫和异形钢槽之间为圆弧面接触。本发明结构简单、受力更加合理,消除了结构的应力集中现象,加强了承受疲劳载荷的能力,使用寿命更长。
The invention discloses a self-adaptive embedded channel of a cylindrical surface in a railway contact network tunnel. The self-adaptive embedded channel comprises a special-shaped steel channel and heart-shaped bolts, wherein the special-shaped steel channel is embedded in the inner wall of the tunnel along the longitudinal direction of a line; the heart-shaped bolts are arranged in the special-shaped steel channel at intervals along the longitudinal direction of the line; the special-shaped steel channel is fixed on the inner wall of the tunnel through an anchor rod; the heart-shaped bolts are arranged in the special-shaped steel channel through tenons; the tenons are matched with tooth grooves in the side wall of the special-shaped steel channel; and the head parts of the heart-shaped bolts are in arc surface contact with the tenons and the special-shaped steel channel. The self-adaptive embedded channel is simple in structure and more reasonable in stress, the stress concentration phenomenon of the structure is eliminated, the fatigue load bearing capacity is enhanced, and the service life is longer.
