Externally-hung sound barrier for rail transit
An externally-hung sound barrier for rail transit comprises a plurality of supporting sets and a plurality of telescopic sound absorption plates, each supporting set is composed of a supporting column, a moving block, a screw and a nut, a first bevel gear is installed at the bottom end of each nut, a limiting block is installed in each first bevel gear, a through hole is formed in each supportingcolumn, a connecting shaft is arranged in each through hole, and a second bevel gear is installed on each connecting shaft. A first threaded sleeve is installed behind the supporting column, a first threaded rod is arranged in the first threaded sleeve, a second threaded sleeve is fixedly installed at the rear end of the movable block, a matching hole is formed behind the telescopic acoustic board, a second threaded rod is arranged in the matching hole, and a second pressing block is installed behind the second threaded rod. According to the rail transit external sound barrier, the use lengthcan be prolonged, noise is weakened, the use requirements of different noise environments are met, installation is convenient, the use requirements of telescopic sound absorption plates of different thicknesses can be met, when replacement or maintenance is needed, the independent telescopic sound absorption plates or supporting sets can be taken out, and other components cannot be affected.
轨道交通外挂式声屏障，包括数组支撑组、数块伸缩吸声板，支撑组由支撑柱、移动块、螺杆、螺母组成，螺母底端安装第一伞齿轮，第一伞齿轮内安装限定块，支撑柱上开设通孔，通孔内设有连接轴，连接轴上安装第二伞齿轮，支撑柱后面安装第一螺套，第一螺套内设有第一螺纹杆，移动块的后端固定安装第二螺套，伸缩吸声板后开设配合孔，配合孔内设有第二螺纹杆，第二螺纹杆后安装第二压紧块。轨道交通外挂式声屏障，可延长使用长度，使噪声减弱，满足不同的噪声环境使用需要，而且安装方便，可以满足不同厚度的伸缩吸声板使用需要，并且在需要更换或维修时，可以将单独的伸缩吸声板或支撑组取出，不会对其他部件造成影响。
