Vibration reduction fastener with double transverse limiting and low vertical rigidity
The invention relates to a vibration reduction fastener with double transverse limiting low vertical rigidity. The fastener comprises a double-end stud (2), and an upper nut (3), a compression spring(4), a first-layer base plate (6), a first-layer elastic plate (7), a second-layer base plate (8), a second-layer elastic plate (9), and a coupling plate (10), wherein the double-end stud (2) passes through the upper nut (3), the compression spring (4), the first-layer base plate (6), the first-layer elastic plate (7), the second-layer base plate (8), the second-layer elastic plate (9), and the coupling plate (10) successively from top to bottom; and the second-layer elastic plate (9) and the coupling plate (10) are sequentially paved on the ballast bed sleeper; a boss (801) and a steel sleeveseat (802) are arranged on the second-layer base plate (8), an anti-shearing steel sleeve (11) is pre-pressed on the steel sleeve seat (802), the boss (801) penetrates through the second-layer elastic plate (7) and the first-layer base plate (6) which are sequentially arranged above the boss (801), and the first-layer base plate (6) is connected with a steel rail (1) through an elastic strip. Compared with the prior art, the vibration reduction fastener has lower vertical rigidity, and meanwhile, the bidirectional transverse limiting structure is arranged, so that the damping effect of the fastener is improved.
本发明涉及一种带双横向限位低垂向刚度的减振扣件，包括双头螺柱(2)以及双头螺柱(2)从上到下依次穿过的上螺母(3)、压缩弹簧(4)、第一层垫板(6)、第一层弹性板(7)、第二层垫板(8)、第二层弹性板(9)、耦合板(10)，所述的第二层弹性板(9)和耦合板(10)依次铺设于道床轨枕上，所述的第二层垫板(8)上设有凸台(801)和钢套座(802)，所述的钢套座(802)上预压防剪钢套(11)，所述的凸台(801)穿过依次其上方的第二层弹性板(7)和第一层垫板(6)，所述的第一层垫板(6)通过弹条(13)与钢轨(1)连接。与现有技术相比，本发明具有较低的垂向刚度，同时设置了双向横限位结构，提高了扣件的减振效果。
