A high-speed train function zone pantograph slide plate and its manufacturing process

Abstract

The invention discloses a high-speed train function partition pantograph slide plate, according to the actual wear and tear of the pantograph slide plate, the material composition partition of the slide plate is carried out: the front and rear edges of the slide plate each have a quarter area to improve the physical and mechanical properties and friction of the slide plate Wear performance: The middle part of the slide plate is based on the composition of the impregnated metal slide plate, and the raw materials that improve the arc ablation wear resistance are added. The invention specifically improves the mechanical and electrical performance of the skateboard, reduces the pantograph-catenary accident probability, and prolongs the service life of the skateboard. The quarter area at each end of the slide plate is two areas S1 and S3 that focus on strengthening the mechanical wear resistance; the half area in the middle of the slide plate is the S2 area that focuses on enhancing the arc wear resistance; among them, the components of S1 and S3 same.

Description

technical field [0001] The invention relates to the technical field of pantograph slide plate preparation for high-speed trains, in particular to a pantograph slide plate used for trains. Background technique [0002] High-speed railways are widely used all over the world because of their advantages such as less pollution, high punctuality, and large carrying capacity. Pantograph-catenary relationship, wheel-rail relationship, and fluid-solid coupling relationship are the three basic relationships of high-speed train systems. Among them, the pantograph-catenary system is the only way of energy supply for high-speed trains, which brings together many influencing factors such as machinery, electricity, materials, etc., and the pantograph slide plate, as the core component of the pantograph-catenary system, is extremely prone to mechanical shock during use , current-carrying friction and arc ablation, the traditional pantograph sliding plate is prone to breakage and falling of...

AI Technical Summary

Problems solved by technology

However, its adhesive wear is serious, and its arc resistance is insufficient, so it is easy to cause serious ablation to the slide plate and catenary wire

The pure carbon slide plate has low wear on the wire and can prolong the service life of the wire, but its inherent resistance is large and the collection capacity is small, resulting in a high temperature in the contact area

Metal-impregnated slides have the advantages of carbon slides and metal slides, but in actual conditions, their electrical and thermal conductivity and impact resistance are still insufficient, and their relative strength is low. During operation, blocks are prone to drop, which can easily lead to pantograph-catenary accidents.

Carbon fiber skateboard has excellent friction and wear properties, mechanical properties and electrical conductivity, and is the most suitable skateboard material. However, due to its high cost, large-scale production has not yet been realized, so it cannot be widely used in high-speed trains at this stage.
