Adjustable steel rail vibration absorber and steel rail vibration absorption system
The invention provides an adjustable steel rail vibration absorber which is characterized by comprising a pair of vibration absorption wedge blocks used for being attached to the waist portions of the two sides of a steel rail and absorbing vibration energy of the steel rail; and the at least one balancing weight is detachably connected to the non-binding surface of the vibration absorption wedge block and is used for adjusting the vibration frequency of the steel rail. According to the adjustable steel rail vibration absorber, the pair of vibration absorption wedge blocks are attached to the waists of the two sides of the steel rail, so that vibration energy of the steel rail can be effectively absorbed; the balancing weights are detachably connected to the vibration absorption wedge blocks, the vibration frequency of the steel rail can be changed by adjusting the number of the balancing weights, the vibration characteristic frequency of the steel rail in different areas can be adapted, and the actual engineering condition is better met. Therefore, the adjustable steel rail vibration absorber has higher flexibility and adaptability, is suitable for rails in different areas, can achieve ideal vibration and noise reduction effects, reduces the construction cost of the rails, and reduces the difficulty of later maintenance.
本发明提供了一种可调式钢轨吸振器，其特征在于，包括：一对吸振楔块，用于贴合在钢轨的两侧腰部，吸收钢轨的振动能量；以及至少一个配重块，可拆卸地连接在吸振楔块的非贴合面上，用于调节钢轨的振动频率。由于该可调式钢轨吸振器采用一对吸振楔块贴合在钢轨的两侧腰部，能够有效吸收钢轨的振动能量；配重块可拆卸地连接在吸振楔块上，通过调整配重块的数量，能够改变钢轨的振动频率，适应不同区域钢轨的振动特征频率，更好地符合实际工程情况。因此，可调式钢轨吸振器具有较高的灵活性和适应性，适用于不同区域的轨道，能够达到理想的减振降噪效果，降低轨道建设的成本，同时减少了后期维护的难度。
