Noise reduction structure for track
The invention belongs to the technical field of track noise reduction, and particularly relates to a noise reduction structure for a track. The noise reduction structure comprises two groups of steel rails and sleepers, the two groups of steel rails are erected on two sides of the sleepers in parallel, noise reduction assemblies are arranged at the joints of the steel rails and the sleepers, and each noise reduction assembly comprises a pressure-bearing main plate, a fixing transverse column and a pressing linkage rod, wherein top of the pressure-bearing main plate is fixedly connected with the bottom of the corresponding steel rail, the two ends of the fixing transverse column are transversely connected with the inner walls of the two sides of the corresponding sleeper, and the top end of the pressing linkage rod is movably connected with the fixing transverse column. The noise reduction device has the advantages that a liquid passing lower section descends and is inserted into a liquid inlet, a liquid passing pipeline is communicated and connected with a liquid inlet pipeline in a liquid passing block, so that liquid enters a noise reduction cavity, the noise reduction assembly is cooled or frozen through the heat capacity ratio of water, and the service life of the noise reduction assembly is prolonged; when a train runs through the steel rail, noise generated by friction is conducted to the noise reduction cavity through resonance, and the noise is absorbed through resonance with water.
本发明属于轨道降噪技术领域，具体涉及一种轨道用降噪结构，包括两组钢轨、枕木，两组所述钢轨平行架设于枕木两侧，所述钢轨与枕木连接处设有降噪组件，所述降噪组件包括承压主板、固定横柱、下压联动杆，所述承压主板顶部与钢轨底部固定连接，所述固定横柱两端横向连接枕木两侧内壁，所述下压联动杆顶端与固定横柱活动连接。本发明的优点在于通液下段下降插入进液口，通液管道与通液块内的进液管道导通连接，使液体进入降噪腔，利用水的热容比对降噪组件进行降温或者防冻，延长降噪组件的寿命，同时，在列车行驶过钢轨时摩擦产生的噪音通过共振传导至降噪腔，噪声通过与水共振，将噪音进行吸收。
