Sound insulation device for expansion joint of high-speed railway bridge
The invention discloses a high-speed railway bridge expansion joint sound insulation device, and relates to the technical field of expansion joint sound insulation, the high-speed railway bridge expansion joint sound insulation device comprises an expansion joint sound insulation device body, fixing plates are arranged at the top and the bottom of the expansion joint sound insulation device body, and steel bars are fixedly connected to the two sides of the expansion joint sound insulation device body; the expansion joint sound insulation device body comprises a first supporting plate and a second supporting plate, and the top and the bottom of the first supporting plate are fixedly connected with the bottom and the top of the fixing plate correspondingly. According to the expansion joint sound insulation device, through cooperation of a connecting plate and a second supporting rod, when a train passes through the top of the expansion joint sound insulation device body, vibration force generated by the train is utilized, a second protruding block makes contact with a scraping plate, the scraping plate rotates under the action of a movable shaft, accumulated water in a third groove is scraped away, and the sound insulation effect is improved. The problem that parts are rusted due to the fact that an existing expansion joint sound insulation device cannot drain accumulated water is solved, and the effects of draining the accumulated water and preventing the parts from being rusted are achieved.
本发明公开了一种高速铁路桥梁伸缩缝隔声装置，涉及伸缩缝隔声技术领域，包括伸缩缝隔声装置本体，所述伸缩缝隔声装置本体的顶部与底部均设置有固定板，所述伸缩缝隔声装置本体的两侧固定连接有钢筋，所述伸缩缝隔声装置本体包括第一支撑板和第二支撑板，所述第一支撑板的顶部、底部分别与固定板的底部、顶部固定连接。本发明通过采用连接板和第二支撑杆的配合，当列车经过伸缩缝隔声装置本体的顶部时，利用列车产的震动力，使第二凸块接触刮板，刮板在活动轴的作用下进行旋转，对第三凹槽内部的积水进行刮除，解决了现有伸缩缝隔声装置无法将积水排出导致零件锈蚀的问题，达到了排出积水，防止零件锈蚀的效果。
