Vibration reduction fastener system capable of resisting transverse torsion and low vertical rigidity of steel rail
The invention relates to a vibration reduction fastener system capable of resisting transverse torsion and low vertical rigidity of a steel rail. The system mainly comprises an anchor bolt (2), a U-shaped pre-pressing guide sleeve (5), a first-layer base plate (6), a middle elastic plate (7), a second-layer base plate (8) and a coupling plate (9), wherein the first-layer base plate (6) is arrangedbetween an under-rail base plate (10) and the middle elastic plate (7), and a U-shaped boss is arranged on the board, the second-layer base plate (8) is arranged between the middle elastic plate (7)and the coupling plate (9), a U-shaped boss (801) is arranged on the plate, and a U-shaped pre-pressing guide sleeve (5) is arranged between the U-shaped boss (601) and the U-shaped boss (801). Compared with the prior art, the U-shaped pre-pressing guide sleeve (5) is arranged to control transverse displacement of the first-layer base plate (6) and the second-layer base plate (8), so the vibrationreduction fastener can set low vertical rigidity, the system vibration reduction effect is good, and rail traffic vibration noise pollution is reduced.
本发明涉及一种抗钢轨横向扭转低垂向刚度的减振扣件系统，主要包括锚固螺栓(2)、U型预压导套(5)、第一层垫板(6)、中间弹性板(7)、第二层垫板(8)、耦合板(9)，所述的第一层垫板(6)设置在轨下垫板(10)和中间弹性板(7)之间，且板上设置U型凸台(601)，所述的第二层垫板(8)设置在中间弹性板(7)和耦合板(9)之间，且板上设置U型凸台(801)，所述的U型凸台(601)与U型凸台(801)之间设置U型预压导套(5)。与现有技术相比，本发明中设置U型预压导套(5)控制第一层垫板(6)和第二层垫板(8)的横向位移，从而使得减振扣件可设置较低垂向刚度，系统减振效果好，降低了轨道交通振动噪声污染。
