Staggered vibration reduction fastener system for urban railway
The invention discloses a staggered vibration reduction fastener system for urban railways, which belongs to the field of rail transit and comprises an embedded sleeve embedded into a sleeper, an elastic strip, a gauge block, an anchor bolt connected with the embedded sleeve in a matching manner, a T-shaped bolt and a nut matched with the T-shaped bolt, a buffer base plate, a first rigid base plate, an elastic base plate, a second rigid base plate and an under-rail base plate are sequentially arranged between the sleeper and the steel rail in the direction from the sleeper to the steel rail. A first boss and a second boss are arranged on each of the two sides of the first rigid base plate in the transverse direction. A first through hole is formed in the second rigid base plate corresponding to the first boss, a groove is formed in the second rigid base plate corresponding to the second boss, a check block is arranged between the second boss and the groove, an elastic strip base is further arranged on the second rigid base plate, and a T-shaped groove is formed in the elastic strip base corresponding to the T-shaped bolt. According to the staggered vibration reduction fastener system for the urban railway, the operation characteristics that the urban railway is high in speed and small and large in curve radius can be integrally met, and the vibration reduction reference requirement is met.
本发明公开了一种市域铁路错列式减振扣件系统，属于轨道交通领域，包括预埋入轨枕的预埋套管、弹条、轨距块和与预埋套管匹配连接的锚固螺栓、T型螺栓和与之匹配的螺母，轨枕和钢轨之间沿轨枕至钢轨方向依次设置有缓冲垫板、第一刚性垫板、弹性垫板、第二刚性垫板和轨下垫板。第一刚性垫板横向上两侧每侧各设置有一个第一凸台和一个第二凸台。第二刚性垫板对应第一凸台开设有第一通孔，第二刚性垫板对应第二凸台开设有凹槽，第二凸台与凹槽之间设置有挡块，第二刚性垫板上还设置有弹条座，弹条座对应T型螺栓开设有T型槽。本发明的市域铁路错列式减振扣件系统，整体能够满足市域铁路车速快、曲线半径小且多的运营特点，且满足减振引用需求。
