The invention discloses an urban rail transit contact rail system with a noise reduction function, which comprises a system main body, an opening and closing device and a pull-down device, the system main body is a mounting platform of the pull-down device and the opening and closing device, and a plurality of elastic parts are arranged on the system main body and can play a role in degrading sound while the whole device vibrates. The opening and closing device is further provided with an isolation top, external sound can be isolated, the pull-down system is driven through vibration of the device, the mechanical arm system drives a mechanical arm steel cable and the isolation top to act, noise is absorbed into the device, and the device is opened for the next round of noise reduction after being digested, and the pull-down system is provided with a plurality of gears for transmission. The invention aims to reduce the starting power and start the system more easily.
本产品公开一种具有降噪功能的城市轨道交通接触轨系统,包括系统主体、开合装置、下拉装置,系统主体是下拉装置和开合装置的安装平台,其中系统主题上设置有多个弹性元件,可起到整个装置在震动的同时对声音的一个降解的作用,开合装置上还设置有隔离顶,可隔离外在的声音,通过装置的震动带动下拉系统,机械臂系统带动机械臂钢索,带动隔离顶进行动作,将噪音吸纳入装置内部,消化后再进行张开进行下一轮的降噪,下拉系统设置有多个齿轮传动,其目的是减轻启动的动力,更加轻便的启动其系统。
