Steel rail damping device
The invention relates to the technical field of noise reduction equipment and discloses a steel rail damping device. The steel rail damping device comprises at least one damping block and at least two clamps used for pressing the damping block on a rail web of a steel rail, wherein each clamp comprises a base, an adjusting rod and an adjusting screw, the base is located below the steel rail and is in a U shape, the left side and the right side of the base are each provided with a supporting leg, the two supporting legs are located on the left side and the right side of the steel rail respectively, the two adjusting rods are rotationally connected with the supporting legs respectively, and tail ends of the two adjusting rods are connected with the damping blocks through adjusting screws respectively and press the damping blocks on rail webs on the left side and the right side of the steel rail respectively; the adjusting screw is in threaded connection with the adjusting rod; the damping block is provided with a vibration absorption cavity filled with damping materials, one side of the damping block is provided with a buffer pad connected with the rail web in a matched mode, and the other side of the damping block is fixedly connected with the adjusting screw or connected with the adjusting screw in a sliding mode through a pressing structure. The device has advantages of dual vibration and noise reduction and convenience in disassembly and assembly.
本发明涉及降噪设备的技术领域，公开了一种钢轨减振装置，包括阻尼块和用于将阻尼块压紧在钢轨的轨腰上的夹具，夹具至少设有一个，阻尼块设有两个，夹具包括底座、调节杆和调节螺丝，底座位于钢轨的下方，底座呈U型，底座的左右两侧分别设有一支脚，两个支脚分别位于钢轨的左右两侧，调节杆设有两个且分别与一支脚转动连接，两个调节杆的末端分别通过调节螺丝与每一阻尼块连接并将每一阻尼块分别压紧在钢轨的左右两侧的轨腰上，调节螺丝与调节杆螺纹连接；阻尼块上设有填充有阻尼材料的吸振腔，阻尼块的一侧设有与轨腰配合连接的缓冲垫，阻尼块的另一侧与调节螺丝固定连接或通过压紧结构滑动连接。采用本发明具有双重减振降噪和方便拆装的优点。
