FIELD: electricity.SUBSTANCE: invention is related to the sphere of railways electrification, in particular, to supports of an overhead catenary. The railway overhead catenary bracket includes a hollow rod 1, a bracket 2 made of beam channels 3, 4, and a link assembly 5 for the hollow rod 1 with the bracket 2. The hollow rod 1 and bracket 2 are pivotally connected to a support 6 through link assemblies 7, 8 with control ports 9, 10 made in them. The link assembly 5 for the hollow rod 1 with the bracket through a cross bar 11 and a saddle 12 interacts with a carrier cable 13 of the overhead catenary. The link assembly 5 for the hollow rod 1 with the bracket 2 is made as a bushing 14 with a lateral through opening 15 installed on the hollow rod 1 and placed between the beam channels 3, 4 of the bracket 2. The hollow rod 1, the bracket 2 and the bushing 14 are interconnected by an axle 16 installed into the control ports 9, 10 of the hollow rod 1 and the bracket 2 made of the beam channels respectively and to the lateral through opening 15 of the bushing 14. The bushing 14 is equipped with lugs 17 interacting with the cross bar 11 through axles 18, 19.EFFECT: improved reliability of the support.3 dwg |
