Novel rail transit vibration reduction support
The invention discloses a novel rail transit vibration reduction support which comprises a lower baseplate, an upper top plate and a foundation, the upper top plate is located at the top of the lowerbottom plate. The lower bottom plate is located at the top end of the foundation. An upper top plate rubber plate is arranged at the top end of the lower bottom plate; a lower bottom plate rubber plate is arranged at the bottom end of the lower bottom plate; a rectangular frame is fixedly connected to the top end of the lower bottom plate, an upper spring steel plate and a lower spring steel plateare symmetrically arranged in the rectangular frame up and down, the upper spring steel plate is located at the top end of the lower spring steel plate, the upper spring steel plate is fixedly connected with the upper top plate through upper countersunk bolts, and the lower spring steel plate is fixedly connected with the lower bottom plate through lower countersunk bolts. The vibration reductionsupport has the advantages of being convenient to install and adjust, low in structural height, limited in transverse deviation and limited in longitudinal sliding, the vibration reduction comprehensive performance is larger than 40 dB, the vibration reduction support is suitable for a support of a rail transit plate-type structure ballast bed or a beam-type structure ballast bed, meshing face sliding between a steel rail and a vehicle is avoided, and steel rail abrasion is relieved.
本发明公开了一种新型轨道交通减振支座，包括下底板、上顶板与地基，所述上顶板位于下底板顶端，所述下底板位于地基顶端，所述下底板顶端设有上顶板橡胶板，所述下底板底端设有下底板橡胶板，所述下底板顶端固定连接有矩形框，所述矩形框内上下对称设置有上弹簧钢板与下弹簧钢板，所述上弹簧钢板位于下弹簧钢板顶端，所述上弹簧钢板通过上沉头螺栓与上顶板固定连接，所述下弹簧钢板通过下沉头螺栓与下底板固定连接；减振支座具有安装调整方便，结构高度低，横向偏移限制，纵向有限滑移，减振综合性能大于40dB的优点，适用于轨道交通板式结构道床或梁式结构道床的支座，避免钢轨与车辆出现咬合面滑移，减缓钢轨磨损。
