Problems solved by technology
[0002] In recent years, with the vigorous development of the rail transit industry, the pipelines mounted on the rail vehicles are subject to the complexity of the vibration during the operation of the vehicle, resulting in frequent joint fatigue problems of the pipeline system due to vibration, such as the pipeline system Cracking and the noise caused by pipeline vibration have brought huge hidden dangers to the safe service of rail vehicles. How to reduce and reduce the fatigue damage and noise problems caused by this pipeline connection has become a major issue in improving vehicle operation reliability and comfort. One of the research problems, a simple, reliable, economical and adaptable pipeline suspension device has become the expectation of improving the reliability of railway vehicle pipeline installation

The invention provides a self-damping suspension device for a pipeline of a railway vehicle, which comprises a mounting seat arranged on a railway vehicle body, wherein the bottom of the mounting seatis provided with a shell seat connecting body; the bottom of the shell seat connecting body is hinged with a left side shell and a right side shell through a shell connecting rotating shaft; and theother ends of the semicircular left side shell and semicircular right side shell are connected and fixed through a bolt connecting assembly, so that the left side shell and the right side shell form acircle. According to the device, a pipeline suspension assembly is simple and practical in structure, reliable in installation, low in cost and good in economy, and can be popularized to pipeline suspension application requirements in other fields. According to the device, the pipeline suspension assembly has an ingenious structural design, particularly, the pipeline fixing and locking assembly on the pipeline suspension assembly reduces and absorbs the vibration generated by the rigid connection of a prior pipeline and the vehicle body, and the occurrence of fatigue cracks of the pipeline system due to the vibration generated during the running of the vehicle is greatly reduced.
