Urban rail transit line turnout shock absorber
The invention belongs to the technical field of shock absorption equipment, and relates to an urban rail transit line turnout shock absorber which comprises a rail bearing plate, an elastic body, a base plate and a distance adjusting cover plate; an oval outer inverted cone curved surface is arranged on the outer side of the rail bearing plate; the base plate is provided with an inner cone curvedsurface corresponding to the outer inverted cone curved surface of the rail bearing plate; the outer inverted cone curved surface of the rail bearing plate is connected with the inner cone curved surface of the base plate through elastic body vulcanization; kidney-shaped through holes are formed in the four corners of the base plate respectively; first sawtooth bosses are arranged on the peripheries of the top faces of the kidney-shaped through holes; through holes are formed in the distance adjusting cover plate; second sawtooth bosses are arranged on the bottom face of the distance adjustingcover plate; and the first sawtooth bosses and the second sawtooth bosses are connected in a staggered and clamped mode. The shock absorber can provide three-dimensional elasticity for a track at thesame time, has reverse tensile load bearing capacity and good track gauge keeping and adjusting capacity, and remarkably improves the smoothness of a vehicle passing through the track, the safety stability of a fastener system and the shock absorption and noise reduction performance of the track.
本发明属于减震设备技术领域，涉及一种城市轨道交通线路道岔减振器，包括承轨板、弹性体、底座板及调距盖板；所述承轨板的外侧设置椭圆状的外倒锥体曲面，底座板设有与承轨板的外倒锥体曲面相对应的内锥体曲面，所述承轨板的外倒锥体曲面与底座板的内锥体曲面通过弹性体硫化连接；底座板的四角分别设置腰型通孔，腰型通孔顶面周围设置第一锯齿凸台，调距盖板设有贯通孔，调距盖板底面设置第二锯齿凸台，第一锯齿凸台与第二锯齿凸台错位卡合连接。该减振器能同时为轨道提供三维弹性，并具备反向拉伸载荷承受能力，且拥有良好的轨距保持及调整能力，对车辆过轨的平顺性、扣件系统的安全稳定性及轨道的减振降噪性能具有显著提升。
