Rail transit vibration and noise reduction device and using method
The invention discloses a rail transit vibration and noise reduction device and a using method, and belongs to the technical field of rail transit. The device comprises an arc-shaped sound insulation cylinder which is fixed to the inner wall of a tunnel and used for conducting vibration and noise reduction on a rail, a swing support is fixed to an arc supporting plate, and a forward swing rod is hinged to the swing support; the lower end of the forward swing rod extends out of the sound insulation cavity and then is connected with a forward vibration plate, the forward vibration plate is perpendicular to the longitudinal direction of the tunnel, the upper end of the forward swing rod is hinged to a guide rod through an end connecting rod, the middle of the guide rod is in sliding fit with a guide rod support fixed to the supporting plate, and a first spring is connected between the guide rod and the guide rod support. The guide rod extends out of the guide rod support and then is connected with a special-shaped plate, the surface of the special-shaped plate makes contact with a roller, the roller is rotationally connected to a core rod, the core rod is coaxially arranged on the inner side of a damping cylinder in a sliding and sealing mode, the damping cylinder is fixed to the supporting plate, a second spring is connected between the core rod and the damping cylinder, and the outer side of the core rod is connected with a damping structure matched with damping liquid.
本发明公开了一种轨道交通减振降噪装置及使用方法，属于轨道交通技术领域，装置包括固定在隧道内壁用于对轨道进行减振降噪的弧形隔音筒，弧支撑板上固定有摆动支座，摆动支座铰接有正向摆杆，正向摆杆的下端伸出隔音腔后连接有正向振动板，正向振动板与隧道的纵向垂直，正向摆杆的上端通过端部连杆与导杆铰接，导杆的中部与支撑板上固定的导杆支座滑动配合，导杆与导杆支座之间连接有第一弹簧，导杆伸出导杆支座后连接有异形板，异形板的表面与滚轮接触，滚轮转动连接在芯杆上，芯杆同轴滑动密封设置在阻尼筒的内侧，阻尼筒固定在支撑板上，芯杆与阻尼筒之间连接有第二弹簧，芯杆的外侧连接有与阻尼液进行配合的阻尼结构。
