Vibration reduction fastener system
The invention belongs to the technical field of urban rail transit, and particularly relates to a vibration reduction fastener system which comprises an upper iron base plate, a lower bottom plate, a middle vibration reduction pad, an under-rail vibration reduction pad, an under-plate vibration reduction pad, a middle vibration isolation plate, an insulating coupling plate and a self-locking limiting structure. The insulating coupling plate is laid on the ground, and the lower bottom plate is mounted above the insulating coupling plate; a self-locking buckle is arranged and embedded into the mounting groove, so that the lower bottom plate and the upper iron base plate are limited, it is guaranteed that the lower bottom plate, the upper iron base plate and components in the gap between the lower bottom plate and the upper iron base plate are kept stable, and the phenomenon that the vibration reduction fastener moves and is staggered under the vibration effect of passing of a train is avoided; and through the series connection effect of the middle anti-vibration pad, the under-rail anti-vibration pad and the under-plate anti-vibration pad, the overall rigidity of the fastener is effectively reduced, meanwhile, excessive deformation of the anti-vibration pads is prevented, and therefore it is guaranteed that the fastener system can normally play a vibration reduction role.
本发明属于城市轨道交通技术领域，具体的说是一种减振扣件系统，包括上铁垫板、下底板、中间减振垫、轨下减振垫、板下减振垫、中间隔振板、绝缘耦合板和自锁限位结构；所述绝缘耦合板铺设在地面，所述绝缘耦合板上方安装有下底板；本发明通过设置自锁扣，并使得自锁扣嵌入安装槽中，使得下底板和上铁垫板受到限位作用，保证下底板和上铁垫板以及之间间隙的部件保持稳定，避免减振扣件在火车经过的振动作用下出现移动错位的现象；并且通过中间减振垫、轨下减振垫和板下减振垫的串联效应，在有效降低了扣件整体刚度的同时防止了减振垫出现过度变形，从而保证了扣件系统能够正常发挥减振作用。
