The invention relates to the technical field of rail transit, in particular to a catenary dropper which comprises a carrier cable clamp and a contact wire clamp, a dropper wire is arranged between the carrier cable clamp and the contact wire clamp, and heart-shaped retaining rings connected with the carrier cable clamp and the contact wire clamp respectively are arranged at the two ends of the dropper wire. The heart-shaped retaining ring is matched with the hanging rings on the carrier cable clamp and the contact wire clamp to form a loop chain structure, and in order to reduce the moving space of the heart-shaped retaining ring and prevent the heart-shaped retaining ring and the retaining ring from being damaged by large impact force, a buffer cushion block is arranged in the heart-shaped retaining ring, so that the reliability of the dropper is improved.
本发明涉及轨道交通技术领域,具体涉及接触网吊弦,该接触网吊弦包括承力索线夹和接触线线夹,在承力索线夹和接触线线夹之间设置有吊弦线,吊弦线两端均设置有分别与承力索线夹和接触线线夹连接的心形护环,心形护环与承力索线夹和接触线线夹上的吊环配合形成环链结构,为了减少心形护环的活动空间,避免大冲击力损坏心形护环和护环,在所述的心形护环内设置有缓冲垫块,从而提高了该吊弦的可靠性。
