Contact line clamp, dropper and contact suspension

Abstract

The invention provides a contact line clamp, a dropper and a contact suspension, wherein the contact line clamp comprises a U-shaped clamp, a bolt and a nut; the U-shaped clamp is provided with two oppositely extending extension parts, the two extension parts are respectively provided with a first through hole and a second through hole, and the first through hole and the second through hole are arranged oppositely; after passing through the first through hole and the second through hole, the bolt is fixed on the bottom of the U-shaped clamp by the nut. Among the contact line clamp, the dropper and the contact suspension which are provided by the invention, the contact line clamp adopts the U-shaped clamp as a main body and utilizes the nut to fix the bolt on the extension parts of the U-shaped clamp, so that a certain space is defined by the U-shaped clamp and the bolt, the dropper can move relative to the contact line clamp after passing through the space, consequently, the contact suspension can be stabilized and stopped as soon as possible when disturbed by an external environment to fluctuate greatly, and thereby the safety of the contact suspension is enhanced.

Description

Technical field [0001] The invention relates to mechanical technology, in particular to contact wire clamps, hanging strings and contact suspension. Background technique [0002] The catenary system of rail transit engineering, including the catenary, rail loop, feeder and return line, is the direct link in the rail transit power supply system to supply power to the EMU. The catenary is a kind of transmission grid laid on the track and kept a certain distance from the top of the railway track. Through the sliding contact between the pantograph (or current collector) of the EMU and the catenary, the traction power enters the EMU from the catenary and drives the traction motor to make the train run. The commonly used catenary is composed of contact suspension, pillars and foundation. [0003] At present, the contact suspension is mostly composed of load-bearing cables, contact wires, hanging strings and other devices, and its function is to conduct electrical energy to the power su...

AI Technical Summary

Problems solved by technology

[0005] The invention provides a contact wire clip, suspension string and contact suspension, which is used to solve the problem in the prior art that the contact suspension produces large fluctuations when it is disturbed by the external environment, which leads to the breakage of the catenary or the occurrence of large arc cuts
