Non-backing plate turnout steel rail fastener system
According to the non-base-plate turnout steel rail fastening system, the top face of a concrete switch tie is provided with two concrete blocking shoulders, internal thread sleeves are embedded in the inner sides of the concrete blocking shoulders, a rail bearing groove is formed between the internal thread sleeves, and a steel rail is installed in the rail bearing groove; a gauge apron is arranged above the internal thread casing pipe, the outer side face of the gauge apron is an inclined face inclining towards the outer side of a line, the inner side face of the concrete retaining shoulder is a slope with the inclination angle consistent with that of the inclined face, and the inclined face is tightly attached to the slope. An omega-shaped elastic strip is arranged above the gauge apron and is in threaded connection with the internal thread sleeve after penetrating through the omega-shaped elastic strip and the gauge apron through a switch tie bolt, and the omega-shaped elastic strip is buckled and pressed above the gauge apron; a gauge block is arranged between the inner side of the gauge baffle and a rail limb of the steel rail, and the gauge block is buckled and pressed through an omega-shaped elastic strip, so that the gauge block is buckled and pressed on the rail limb of the steel rail. The transverse impact resistance is high, the gauge keeping capacity is excellent, and the gauge is convenient to adjust.
一种无垫板道岔钢轨扣件系统，其混凝土岔枕顶面具有两个混凝土挡肩，所述混凝土挡肩内侧预埋有内螺纹套管，使内螺纹套管之间形成承轨槽，所述承轨槽中安装有钢轨；所述内螺纹套管的上方设置有轨距挡板，且轨距挡板的外侧面为向线路外侧倾斜的斜面，所述混凝土挡肩内侧面为与所述斜面倾斜角度一致的斜坡，并使所述斜面与所述斜坡紧贴；所述轨距挡板上方设置有ω形弹条，并通过岔枕螺栓穿过ω形弹条、轨距挡板后与内螺纹套管螺纹连接，将ω形弹条扣压在轨距挡板上方；所述轨距挡板内侧与钢轨的轨肢之间设置有轨距块，并通过ω形弹条扣压轨距块，使轨距块扣压在钢轨的轨肢上。本发明抵抗横向冲击的能力强、轨距保持能力优良、轨距调整方便。
