The invention discloses an electrified railway contact net positioner with a damping joint, and belongs to the field of fluid machinery and railway equipment. The positioner comprises a positioning stand column, a positioning support, a positioning pin shaft, a positioning pin shaft fixing pin, a positioner damping joint, a positioner lower connecting plate, a positioner first connecting screw rod, a positioner second connecting screw rod, a positioner upper connecting plate and a positioner body. According to the invention, when the positioner swings, the lower positioner connecting plate and the upper positioner connecting plate drive the damping joint core shaft to rotate relative to the damping joint shell to form viscous torque by utilizing the relationship of viscosity, velocity gradient and the like of the viscous working fluid, so that the swing amplitude and frequency of the positioner are effectively reduced, and the positioning precision is improved. And safe operation of the electrified railway overhead line system is ensured. The electrified railway contact net positioner with the damping joint is simple in structure, fully guarantees product quality, improves product reliability and has wide application prospects.

    本发明公开了一种带阻尼关节电气化铁路接触网定位器,属于流体机械和铁路装备领域。定位器包括定位立柱、定位支座、定位销轴、定位销轴固定销、定位器阻尼关节、定位器下连接板、定位器第一连接螺杆、定位器第二连接螺杆、定位器上连接板和定位器。本发明利用粘滞工作液的粘性及速度梯度等关系,当定位器发生摆动时,通过定位器下连接板和定位器上连接板,带动阻尼关节芯轴产生相对于阻尼关节外壳的旋转,形成粘滞力矩,有效降低定位器的摆动幅值和频率,保障电气化铁路接触网的安全运行。本发明提出的一种带阻尼关节电气化铁路接触网定位器,结构简单,充分保障了产品质量,提高了产品的可靠性,具有广泛的应用前景。
