Abstract

The utility model discloses an electric locomotive pantograph bending bow carbon slide board, which comprises an aluminum slot plate (1), a carbon strip (2) and a vent pipe (7), wherein the carbon strip (2) is connected with the aluminum slot plate (1) through adhesive (5), and a contact surface of the aluminum slot plate (1) and the carbon strip (2) is designed into a contact surface with concave-convex stripes (11) and (12). The electric locomotive pantograph bending bow carbon slide board removes a copper wire net and a brass plate in an existing product design, a downward concave part of the aluminum slot plate is filled with the adhesive, the upward convex part is directly contacted with the carbon strip to form a conductor, good electrical conductivity between the carbon strip and the aluminum slot plate is guaranteed, and the use is safer and more reliable.

Description

Block of bow collector of electric locomotive tortuous bow carbon slide plate

Technical field

The utility model relates to a kind of block of bow collector of electric locomotive carbon slide plate, especially a kind of tortuous bow carbon slide plate.

Background technology

Electric locomotive pantograph sliding plate is used for the electrified railway high speed train, and the required electric power of train transmits by pantograph pan.Difference according to material technology is divided into three kinds: ferrous based powder metallurgical slide plate, copper-base powder metallurgy slide plate and carbon slide plate.The carbon slide plate is compared with iron-based slide plate, copper base slide plate, in service life and to aspect the abrasion of copper electrical network, has very big advantage.But there are some defectives in existing product on structure design, traffic safety is formed to threaten sometimes, and reason is as follows:

1, the existing product structure mainly comprises: carbon bar, hollow aluminium frid, breather pipe, copper wire gauze, latten(-tin) and the adhesion agent made by brass pipe.Be cushioning copper wire gauze, latten(-tin) and ventilation brass pipe in the middle of carbon bar and aluminium frid during manufacturing, carbon bar and aluminium frid bonded together heating cure then by adhesion agent.Because the requirement of power transmission after carbon bar and aluminium frid are bonding, by the adhesion agent after solidifying, must form conductor, just can make power network current finally reach locomotive by carbon bar, aluminium frid etc.The used high temperature adhesive of structure design is an insulator, and the theory action of cushioning copper wire gauze and latten(-tin) is to be communicated with current path between carbon bar and aluminium frid.But, in the bonded assembly operating process of actual production, because the gap of carbon bar and aluminium frid is difficult to guarantee, be easy at copper wire gauze two sides formation insulation glue-line, the conductive effect that out of reach is desirable, even contacting to some extent between carbon bar bottom and the aluminium frid also only is that local point-like contacts, be difficult to guarantee the reliability and stability of carbon slide plate quality, and the resting period is slightly long, surface, aluminium frid bonding part forms alumina layer easily, causes aluminium type groove and carbon bar contact resistivity to increase, when big electric current passes through, sometimes will puncture aluminium frid or the explosion of carbon bar, cause train operation accident.

2, the breather pipe in the middle of the carbon slide plate adopts brass pipe, to be the carbon slide plate cause the fracture of carbon bar because of the electrical network collision or may wear in limited time because of carbon slide plate carbon bar in the driving process theory action, brass pipe fracture or grind away and breathe freely, thus bow falls immediately automatically, avoid taking place accident between pantograph.But, the character decision of metal brass pipe (or other metal materials), its toughness is extremely strong, can not in time rupture.Therefore, the ventilation brass pipe is actual does not have an effect of protecting bow net safety because of wearing and tearing gas leakage.

Summary of the invention

The purpose of this utility model is exactly in order to overcome the above problems, and provides a kind of electric conductivity good, safe and reliable block of bow collector of electric locomotive tortuous bow carbon slide plate.

The utility model block of bow collector of electric locomotive tortuous bow carbon slide plate comprises aluminium frid, carbon bar, breather pipe, is linked to each other by adhesion agent between carbon bar and the aluminium frid, and the contact surface of aluminium frid and carbon bar is made as the contact surface that has concave and convex stripe.

As a kind of improvement of the present utility model, be provided with copper rivet between aluminium frid and the carbon bar.

As another kind of improvement the of the present utility model, the aluminium frid is made as that both sides are solid, the center is hollow aluminium frid.

As another improvement of the present utility model, the breather pipe interlude is made as the adhesive solidification pipe.

The utility model electric car motorcycle pantograph tortuous bow carbon slide plate has removed copper wire gauze, the latten(-tin) in the existing product design, the contact surface of aluminium frid and carbon bar is made as the contact surface that has concave and convex stripe, when sticking with glue the bonding carbon bar of agent, recessed partially filled adhesion agent, the part of epirelief then direct contact carbon bar forms conductor, so just guarantee the excellent conductive performance between carbon bar and the aluminium frid, guaranteed the unobstructed of current path; And the increase copper rivet with aluminium frid and carbon bar rivet clasp together, has then further increased the absolute reliability that forms conductor between carbon bar and aluminium frid, has guaranteed traffic safety.In addition, aluminium frid center keeps hollow, and A, B both sides change into solid, prevents that copper rivet is loosening, increases its bearing force.The breather pipe interlude adopts the adhesive solidification pipe, and matter is crisp, is integral with the carbon bar shaped, in case the carbon bar has and splits or may wear to limit then lose heart naturally and in time fall bow automatically, avoids the generation of accident between pantograph.

The specific embodiment

As shown in Figure 2, the utility model block of bow collector of electric locomotive tortuous bow carbon slide plate comprises aluminium frid 1, carbon bar 2, breather pipe 7, latten(-tin) of the prior art 3 shown in Figure 1 and copper wire gauze 4 have been removed, the aluminium frid 1 and the contact surface of carbon bar 2 are made the contact surface that has concave and convex stripe, still link to each other between carbon bar 2 and the aluminium frid 1 by adhesion agent 5, aluminium frid 1 recessed part 11 has just been filled adhesion agent 5 naturally, 12 direct contact carbon of the part bar 2 of epirelief forms conductor, has so just guaranteed to have excellent conducting performance between carbon bar 2 and the aluminium frid 1.In addition, be further to increase by 1 absolute reliability that forms conductor of carbon bar 2 and aluminium frid, guarantee traffic safety, designed copper rivet 6, together aluminium frid 1 and carbon bar 2 rivet clasps.A, B both sides and the center of aluminium frid 1 of the prior art shown in Figure 1 are all hollow structure, change that both sides are solid, the center is hollow into, loosening to prevent copper rivet 6, increase its bearing force.

In addition, metal tube of the prior art is still adopted at breather pipe 7 two ends, is convenient to weld with the external metallization valve.Breather pipe 7 interludes adopt the adhesive solidification pipe, and matter is crisp, form one with carbon bar 2, lose heart in case carbon bar 2 has to split or may wear to limit breather pipe 7 nature that can rupture, and in time fall bow automatically, avoid the generation of accident between pantograph.

The utility model block of bow collector of electric locomotive tortuous bow carbon slide plate is applicable to the block of bow collector of electric locomotive carbon slide plate and the rail vehicle carbon slide plate of all tortuous bow specifications.
