Adjustable high-elastic strip fastener structure for heavy freight railway
The invention discloses an adjustable high-elastic strip fastener structure for a heavy freight railway, which comprises a steel rail mounted on a rail bearing surface of a sleeper, gauge aprons are symmetrically arranged on the left and right sides of the steel rail on the rail bearing surface of the sleeper, bolt positioning holes are formed in the gauge aprons, and upright post positioning holes are symmetrically formed in the front and rear sides of the bolt positioning holes; the gauge apron is provided with an embedded iron base which is downwards and fixedly connected with the sleeper, a T-shaped bolt penetrates through a bolt positioning hole, the side, away from the steel rail, of the gauge apron serves as the outer side, an arc groove is formed in the outer side of the gauge apron, and the outer side of the W-shaped elastic strip is clamped in the arc groove; insulating gauge blocks are arranged between the inner sides of the gauge baffles and the steel rails; and a gauge apron lower height adjusting base plate structure is arranged on the lower side of the gauge apron. The adjustable high-elastic strip fastener structure is simple in structure, high in strength and fast in construction, the problem of rail height adjustment can be solved, and the requirements of heavy freight railways for the structure, strength, service life, bearing capacity, anti-aging performance and the like of the fastener can be met.
本发明公开了一种重型货运铁路用可调高弹条扣件结构，包括安装于轨枕承轨面上的钢轨，轨枕承轨面上位于钢轨的左右两侧对称设有轨距挡板，轨距挡板上设有螺栓定位孔，在螺栓定位孔的前后两侧还对称设有立柱定位孔；由轨距挡板设有向下与轨枕固定连接的预埋铁座，由螺栓定位孔穿过设有T型螺栓，以轨距挡板远离钢轨的一侧为外侧，轨距挡板在其外侧处设有圆弧凹槽，W型弹条的外侧卡接在圆弧凹槽中；轨距挡板的内侧与钢轨之间均设有绝缘轨距块；所述轨距挡板的下侧设有轨距挡板下调高垫板结构。本发明结构简单、强度高、施工快，能解决轨道调高问题，能够满足重型货运铁路铁路，对扣件的结构、强度、使用寿命、承载能力、抗老化性能等的要求。
