The invention relates to a novel rigid suspension arm for a contact network. The suspension arm comprises a base, a swing arm structure and a wire clamp, the swing arm structure comprises a pair of first swing arms and a pair of second swing arms, one ends of the pair of first swing arms are connected with the base, the other ends of the pair of first swing arms are connected with the pair of second swing arms respectively, and the other ends of the pair of second swing arms are connected with the wire clamp; the connecting parts of the two ends of the pair of first swing arms and the pair of second swing arms can be rotationally adjusted, and the pair of adjusted first swing arms and the pair of adjusted second swing arms are arranged in parallel, so that the fixing part of the wire clamp is always parallel to the base; during installation, the base is parallel to a track surface or a pantograph, so that the wire clamp is always kept vertical to the pantograph no matter how the angles of the first swing arm and the second swing arm are adjusted; the method can be suitable for various tunnels with different sections, and is large in adjusting margin, high in adaptability and wide in application prospect.
本发明涉及一种新型接触网刚性悬挂吊臂,所述吊臂包括底座、摆臂结构和线夹;所述摆臂结构包括一对第一摆臂和一对第二摆臂,一对所述第一摆臂一端与底座连接,另一端分别与一对所述第二摆臂连接,一对所述第二摆臂的另一端与线夹连接;一对第一摆臂和一对第二摆臂两端的连接处可转动调节,且调节后的一对第一摆臂和一对第二摆臂均分别平行设置,使得线夹固定处始终与底座平行;在安装时,底座与轨道面或受电弓平行,使得第一摆臂和第二摆臂无论如何调整角度,线夹始终与受电弓保持垂直;本发明可适用于多种不同断面的隧道,且调节裕度大、适应性强、应用前景广阔。
