The invention relates to an anti-loosening noise-reducing brake rail, and belongs to the technical field of high-frequency noise reduction in railway freight vehicle marshalling stations. Comprising a rolling brake rail main body, a noise reduction hole, a noise reduction material and a graphite material are arranged on a rail surface, inclined surfaces are forged at two ends of the brake rail surface, a fixed mounting hole and an anti-loosening device (an anti-loosening fixing plate, an anti-loosening wrench and an anti-loosening screw) are arranged on a rail waist, the noise reduction hole is formed in the rolling brake rail main body, and the noise reduction material and the graphite material are filled in the noise reduction hole. An inclined plane is forged at the end of the rail surface to form a horn mouth, a fixed mounting hole is formed in the rail web, and the anti-loosening device is connected and mounted together with the integral anti-loosening noise-reducing brake rail on site. According to the anti-loosening noise-reducing brake rail, the problem that high-frequency sharp noise generated in the operation process of vehicle speed reducer equipment is reduced is solved, the brake rail is interchanged with an original brake rail, and the railway technical standard limit requirement is met.

    本发明涉及一种防松型降噪音制动轨,属于铁路货运车辆编组站场内,解决降低高频噪音技术领域,包括轧制制动轨主体、轨面设降噪孔、降噪材料和石墨材料、制动轨面二个端头锻制斜面、轨腰设固定安装孔、防松装置(防松固定板、防松扳手、防松螺钉),在轧制制动轨主体设有降噪孔,降噪孔填注降噪材料和石墨材料,轨面端头锻制斜面形成喇叭口,轨腰设有固定安装孔,防松装置待整体防松型降噪音制动轨在现场一起连接安装。本发明防松型降噪音制动轨解决降低车辆减速器设备在作业过程中所发出的阵阵高频尖锐噪音,与原使用制动轨实现互换,符合铁路技术标准限界要求。
