The invention provides a forged taper sleeve type bolt-free contact line positioning wire clamp for an overhead line system, belongs to the technical field of flexible suspension equipment of an electrified railway overhead line system, and aims to solve the problems that a bolt is loosened during long-time actual operation and application of an existing railway contact line positioning wire clamp; and the structural design needs to be further improved. A positioning wire clamp body is a whole positioning wire clamp formed by combining and connecting a left semi-conical positioning clamp body and a right semi-conical positioning clamp body, a positioning pin is connected between the two positioning clamp bodies in an embedded mode, and V-shaped clamping mouths at the bottoms of the two positioning clamp bodies clamp, connect and tightly hold a contact wire. And conical limiting sleeves are embedded on the outer bodies of the two positioning clamp bodies, and a U-shaped fixing pin penetrates through the conical limiting sleeves to be tightly fixed. The whole structure is novel and practical, and is suitable for erecting and hanging contact lines in an electrified railway contact net system.
本发明提供了一种接触网用锻造式锥套型无螺栓接触线定位线夹,属于电气化铁路接触网系统柔性悬挂悬吊器材技术领域,旨在解决现有的铁路接触线定位线夹在长时实际运行应用中会造成螺栓松脱,构造设计有待于进一步改进的问题。它采用的定位线夹主体是由左半圆锥形定位夹体、右半圆锥形定位夹体相互对合组连成为定位线夹整体,在其两个定位夹体的中间嵌连定位销钉、两个定位夹体底部V型夹嘴夹连抱紧接触线,并在其两个定位夹体外体上镶套圆锥型限定位套和由U型固定销穿连锁紧固定。其整体结构新型实用,适用于电气化铁路接触网系统架设悬挂接触线。
