Supporting base structure for track vibration reduction
The supporting base structure comprises a supporting base groove, a supporting base cover plate, an iron base plate, a screw rod and a nut, a supporting bottom plate capable of moving up and down relative to the supporting base groove is arranged in the supporting base groove, and a plurality of spring dampers are fixed to the bottom of the supporting bottom plate; the bottom ends of the multiple spring dampers are fixedly connected with the bottom in a supporting base groove, a first buffering cushion and a second buffering cushion are arranged on the top of the supporting bottom plate, the supporting base cover plate is in threaded connection with an adjusting bolt, and first through holes matched with screws are formed in the four corners of the supporting base cover plate correspondingly. Second through holes matched with the screws are formed in the four corners of the iron base plate respectively, bosses are arranged on the screws, the nuts are in threaded connection with the screws, and the screws penetrate through the first through holes to abut against the top of the supporting bottom plate. A main structure for achieving the vibration reduction function is arranged in the sleeper, the installation height of the fastener is greatly reduced, the rigidity of the vibration reduction structure can be conveniently and rapidly adjusted, and therefore the vibration reduction requirements under different environment conditions are met.
本发明提供了一种用于轨道减振的支撑底座结构，包括支撑底座槽、支撑底座盖板、铁垫板、螺杆和螺母，支撑底座槽内设有相对支撑底座槽可上下移动的支撑底板，支撑底板底部固定有多个弹簧阻尼器，多个弹簧阻尼器底端与支撑底座槽内底部固定连接，支撑底板顶部设有第一缓冲垫和第二缓冲垫，支撑底座盖板螺纹连接有调节螺栓，支撑底座盖板四角处分别设有与螺杆相配合的第一通孔，铁垫板四角处分别设有与螺杆相配合的第二通孔，螺杆上设有凸台，螺母与螺杆螺纹连接，螺杆穿过第一通孔与支撑底板顶部相抵。本发明将实现减振功能的主要结构内置于轨枕中，大大降低扣件的安装高度，且可便捷快速地调整减振结构的刚度，从而满足不同环境条件下的减振需求。
