High-damping fixing structure for ballastless track steel rails
The invention discloses a high-damping fixing structure for ballastless track steel rails. By adopting the high-damping fixing structure, flexural vibration of the steel rails caused by discrete support is effectively inhibited, vibration energy of the steel rails is effectively consumed, vibration and noises can be inhibited, periodic abrasion loss of wheel tracks is improved, dynamic vibration impact of the wheel tracks is effectively alleviated, and transmission of vibration to a sub-rail foundation is weakened. The high-damping fixing structure comprises a steel rail and the sub-rail foundation; through buckling systems which are longitudinally arranged at intervals, the steel rail is fixedly mounted on the sub-rail foundation; one or at least two shearing energy-consumption devices which are arranged longitudinally at intervals can be arranged between the two adjacent buckling systems and positioned on the surface of the sub-rail foundation; each of the shearing energy-consumptiondevices acts upon the steel rail and vertical support is formed by the shearing energy-consumption devices and the steel rail; the shearing energy-consumption devices are provided with a pair of sidestop blocks which are positioned on the two sides of the steel rail; energy-consumption wedged blocks are fixedly arranged on the tops of the side stop blocks; and a clamping device acts upon the two-sided side stop blocks, so that the two-sided energy-consumption wedged blocks are tightly adhered and clamped with the rail waist of the steel rail and a vertical shearing energy-consumption structure is formed.
