Problems solved by technology

In the existing simple suspension of double contact wires, two sets of sling components are fixed side by side on the flat wrist arm to suspend the double contact wires respectively. Installation, operation and maintenance increase the workload
In particular, due to the limitation of the width of the two sling fixing seats, the distance between them is greater than the distance between the two contact wires, which causes the force of the sling stay wire to pull outward on the sling wire clip, which makes the contact wire potentially fall out of groove.

Abstract

The invention provides a double-contact-line integral suspension type sling assembly comprises a sling fixing seat 1, a double-contact-line suspension wire clamp 2 and a sling stay wire 3, the double-contact-line suspension wire clamps 2 are arranged on the two sides of the lower portion of the sling fixing base 1, and the upper ends of the two sling stay wires 3 are connected with the sling fixing base 1 through the first heart-shaped rings 4 respectively. The lower ends of the two sling stay wires 3 are connected with the double-contact-line suspension wire clamps 2 through the second heart-shaped ring 5 respectively, and the two double-contact-line suspension wire clamps 2 are suspended on the two sides of the lower portion of the sling fixing base 1 to form an inverted-V-shaped structure. According to the invention, double contact lines are suspended through one sling assembly, wherein the number of components is small, the weight is reduced, contact hard points are reduced, and the current taking quality of the pantograph is improved.

Description

technical field [0001] The invention relates to the technical field of urban rail transit flexible catenary, in particular to a double catenary integral suspension type sling assembly. Background technique [0002] The sling assembly is one of the important components in the simple suspension wrist-arm device of the flexible catenary in urban rail transit. The suspension point is increased through the sling assembly to reduce the hard point at the suspension point and ensure the contact line within the span of adjacent pillars The speed meets the locomotive driving demand. In the existing simple suspension of double contact wires, two sets of sling components are fixed side by side on the flat wrist arm to suspend the double contact wires respectively. Installation, operation and maintenance increase the workload. In particular, due to the limitation of the width of the two sling fixing seats, the distance between them is greater than the distance between the two contact w...
