Embodiment Construction

[0027] The present invention will be described in further detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0028] The present invention aims at the deficiencies of the prior art, and provides an anti-wear type pre-twisted armored suspension clamp, which is a metal tool for hanging additional wires of electrified railways. Rigidity, reduce the stress and strain at the hanging point, effectively avoid the fatigue damage of the additional wire; at the same time, evenly distribute the gripping force at the hanging point to the entire clamp length (installation length), and reduce the pressure that the hanging point should bear Distribute evenly to both sides to eliminate the damage to the wire caused by stress concentration; the anti-wear bushing at the hanging lug improves the anti-wear performance of...

Abstract

The invention discloses a pre-hinged armored catenarian cleat which comprises a sleeve shell assembly and spiral pre-hinged wire pieces. The sleeve shell assembly is provided with an additional wire mounting hole in the middle position. The pre-hinged wire pieces are winded on the outer surface of the sleeve shell assembly and made to extend towards two sides and winded on an additional wire. The pre-hinged armored catenarian cleat adopts a pre-hinged wire structure, has uniform grip strength, large clamping length and wide clamping range, has no stress concentration, effectively improves the stiffness of the additional wire, reduces the stress and the strain of the additional wire on the hanging point and enhances the anti-fatigue performance of the additional wire. The pre-hinged wire structure can be mounted without using an additional tool, protecting strips can be mounted by hands, and the pre-hinged wire pieces are mounted on the outer sides of sleeve shells, thus the mounting process is simplified, and the mounting time is greatly saved. The rubber gaskets arranged in the sleeve shells can play the role of resisting wear and reducing vibration. The inserted aluminum protection sleeves can be mounted easily and reliably. Due to the adoption of the wear-resisting bushings, the wear resistance of the pre-hinged armored catenarian cleat in the high-speed railway and the windy areas is greatly improved.

Description

technical field [0001] The invention relates to the technical field of railway catenary, in particular to a pre-twisted armored suspension clamp for additional wires. Background technique [0002] With the development of my country's electrified railway, the performance requirements of electrified railway catenary components are getting higher and higher. The additional suspension of catenary generally includes power supply line, return line, positive feeder line, overhead ground line and so on. The additional suspension is set up for the perfection of the power supply system, which is conducive to the improvement of power supply quality and the reduction of adverse effects on adjacent systems. It is an indispensable part to ensure the reliable operation of the power supply system and maintain good power supply quality. [0003] The additional conductors of electrified railways are affected by vibration during operation, especially on the high-speed railways currently under...
