Abstract

The utility model discloses an electric locomotive pantograph straight bow carbon slide board, which comprises an aluminum slot plate (1) and a carbon strip (2), 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 straight 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.

Description

Block of bow collector of electric locomotive directly bends the 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 straight 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:

The existing product structure mainly comprises: carbon bar, aluminium frid, copper wire gauze, latten(-tin), adhesion agent.The carbon bar is installed in the aluminium frid during manufacturing, and cushioning latten(-tin) and copper wire gauze bond together carbon bar and aluminium frid by adhesion agent heating cure then in the middle of carbon bar and aluminium frid.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.

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 block of bow collector of electric locomotive good, safe in utilization directly to bend the carbon slide plate.

The utility model block of bow collector of electric locomotive directly bends the carbon slide plate and comprises aluminium frid, carbon bar, 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.

The utility model electric car motorcycle pantograph directly bends the carbon slide plate and has removed copper wire gauze and 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, protruding part 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.

Description of drawings

Fig. 1 directly bends the structural representation of carbon slide plate for the prior art block of bow collector of electric locomotive.

Fig. 2 directly bends the structural representation of carbon slide plate for the utility model block of bow collector of electric locomotive.

Among the figure, 1. aluminium frid, 2. carbon bar, 3. latten(-tin), 4. copper wire gauze, 5. adhesion agent, 6. copper rivet, the recessed part of 11. aluminium frids, the part of 12. aluminium frid epireliefs.

The specific embodiment

As shown in Figure 2, the utility model block of bow collector of electric locomotive directly bends the carbon slide plate and comprises aluminium frid 1, carbon bar 2, 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 the 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.

The utility model block of bow collector of electric locomotive directly bends railway electric locomotive pantograph carbon slide and the rail vehicle carbon slide plate that the carbon slide plate is applicable to that all directly bend specification.
