The invention relates to the technical field of catenary positioning, and discloses a positioning device suitable for a large-tension high-speed electrified railway catenary system, a positioner is mounted at one end of a positioning support, an electrical connecting wire is connected between the positioner and the positioning support, and a connecting hoop is arranged at the other end of the positioning support; the lower portion of the pressing rivet type rotary double-lug is of a double-lug structure, the upper portion of the pressing rivet type rotary double-lug is of a rod-shaped structure, and the pressing rivet type rotary double-lug is integrally forged and connected with the positioning support in a pressing rivet mode. The other end of the positioner is connected with the positioner pipe in a pressing mode through a copper casting sleeve, a telescopic spring is arranged in the sleeve, and the effects of reducing amplitude and increasing damping are achieved. According to the device, in the actual operation process, when a train travels and passes through, up-down vibration of the positioner is achieved, the limiting effect is achieved, meanwhile, when a contact line expands with heat and contracts with cold, and a positioning wire clamp deflects left and right, the pressing rivet type rotating double lugs can rotate for adjustment, and therefore the requirement in actual operation is met.
本发明涉及接触网定位技术领域,且公开了一种适用于大张力高时速电气化铁路接触网系统定位装置,定位支座的一端安装有定位器,定位器与定位支座之间连接有电气连接线,定位支座的另一端设有连接抱箍;压铆式旋转双耳下部为双耳结构,上部为杆状结构,锻造一体成型,与定位支座连接后采用“压铆”连接;定位器的另一端采用铜铸件套筒与定位器管进行压接连接,套筒内有伸缩弹簧,起到减小振幅,增加阻尼的作用;本装置满足实际运行过程中,列车行驶通过时定位器的上下振动,并有限位作用,同时当接触线热胀冷缩导致定位线夹左右偏转时,压铆式旋转双耳能够转动进行调节,从而满足实际运行中的需求。
