Description
Technical field
The present invention relates to a kind of top cover of electric locomotive car body.
Background technology
Present electric locomotive, electric rail car group top cover material therefor all are metallic material, and be on-insulated.Receiving stream system stream is to be installed on the top cover through insulator, generally, according to present top cover and receive the distance between the streaming system, receives the insulator on the streaming system can satisfy insulating requirements.But for certain particular surroundings, for example at high altitude region, because the air insulation degradation, original design just can not ensure insulating power.Use in the case, will increase usually that to be flowed be the insulation distance between stream and top cover.But because the restriction of vehicle gauge of the locomotive, the way of employing is to compress top cover apart from the distance between rail level, or improvement receives streaming system.But in some cases, the compression top cover can cause vehicle body space to reduce apart from the distance between rail level, and the headroom of doorframe does not meet related standard requirements, or occur some other influence the factor (like the ventilation of locomotive etc.) of locomotive operation; Receive streaming system under existing technical conditions, can not increase its insulation distance and improve.
Summary of the invention
The purpose of this invention is to provide a kind of electric locomotive top cover, solve locomotive or motor train unit in gauge restriction or heavily contaminated area, being installed in being flowed on the top cover is the not enough problem of insulation distance of stream and top cover.
Electric locomotive top cover provided by the invention; The zone of pantograph is installed on the roof and is provided with the insulating composite material layer on every side; The pantograph mount pad is embedded in the middle of the insulating composite material, is outside equipped with at nethermost insulating composite material layer and eliminates static or corona layer.
According to embodiments of the invention, said elimination static or corona layer can be taked following concrete mode.A kind of is outside the insulating composite material layer, to be coated with electroconductive paints; Another kind of mode is at insulating composite material layer external pasting layer of steel wire net.As be coated with electroconductive paints and then contact with corrosion-resistant steel on being installed in top cover through electroconductive paints and form ground connection, eliminate in the insulating barrier bottom issuable static or corona; As paste wire net, and then draw grounding jumper and form ground connection, eliminate in the insulating barrier bottom issuable static or corona; As paste the corrosion-resistant steel wire net, and then contact with the corrosion-resistant steel mounting guide rail that top cover is installed and form ground connection through the corrosion-resistant steel wire net, eliminate in the insulating barrier bottom issuable static or corona.
Said insulating composite material layer can extend to whole roof, and promptly the insulating composite material top cover replaces the original metallic top cover and on casting coping, covers the structure of insulating composite material.It is to be employed in folder foamed materials 12 between the double insulation composite layer; The pantograph mount pad is embedded in the middle of the insulating composite material; The mount pad of other equipment of roof also or be embedded in the middle of the insulating composite material or stick on the bottom of insulating composite material nexine is outside equipped with at nethermost insulating composite material layer and eliminates static or corona layer.
According to embodiments of the invention 1; Pantograph mount pad place at casting coping forms the peviform structure; The peviform structure content is received the pantograph mount pad in the insulating composite material; Other each equipment mount pads are embedded in the middle of the insulating composite material, on insulating composite material and lower surface that the steel top cover contacts, are provided with and eliminate static or corona layer.
Because of insulating composite material 3 is to be connected with casting coping 1 through bonded adhesives 4, for making things convenient for gluing, the peviform structural base at the pantograph mount pad place of casting coping is the removable cover of a bolt together.For eliminating the electrostatic charge that possibly on removable cover, produce, removable cover and car body are connected together with grounding jumper.
According to embodiments of the invention 1; Before insulating composite material layer and steel top cover are bonding; Be placed on the steel top cover on the frock of level earlier; Insulating composite material layer location, leveling (upper surface of guaranteeing three pantograph mount pads is on same plane), leveling method is: at casting coping and the contacted three corrosion-resistant steel places of insulating composite material layer lower surface electroconductive paints, be provided with polylith corrosion-resistant steel bearing cap shim again; The upper surface of guaranteeing three pantograph mount pads through the quantity of increase and decrease corrosion-resistant steel bearing cap shim is on same plane, and guarantees that the electroconductive paints of insulating composite material layer lower surface contacts with stainless steel or stainless steel bearing cap shim.
The muscle that protrusion is arranged on the insulating barrier, the muscle of protrusion are the rigidity that increases insulating barrier on the one hand, are to make things convenient for gluing on the other hand.Around the insulating composite material with the pantograph mount pad around the outside face at muscle and the pantograph mounting pot place on outer (interior) gluing place of muscle, steel top cover or the steel top cover through protrusion form the cavity of a gluing; Glue is clamp-oned the cavity place through pressure, forms firm bonded structure (see figure 2).
The below of the peviform structure at the pantograph mount pad place of casting coping is a removable cover.For eliminating the electrostatic charge that possibly on removable cover, produce, removable cover and car body are connected together with grounding jumper.
Insulating top cover is nontoxic, tasteless; Low temperature resistant, high temperature creep-resisting have good toughness and high intensity, can be in-50 ℃ ~ 80 ℃ scope with the intensive ultraviolet condition under long-term use, ageing resistance is good; Pulling strengrth is 170 MPa ~ 500MPa, and bending strength is 220 MPa ~ 400 MPa, but proportion has only 1/4 ~ 1/3 of steel; Have the excellent electric insulation performance, thick its frequency breakdown voltage of insulating barrier of 15mm is greater than 75kV; Have good thermal property, coefficient of thermal conductivity is 1/1000 ~ 1/100 of a metallic material, and has excellent fireproof performance, oxygen index (OI) >=32.
Insulating composite material can be organic toughened glass or other insulating material that satisfies above-mentioned condition.
The present invention can (like high altitude region, IA) use electric locomotive, electric rail car group under particular surroundings, enlarged the application region of electric locomotive, electric rail car group.
In express locomotive or motor train unit, light-weight design is difficult point of car body (or vehicle) design-calculated, and the present invention also provides a kind of structure and method for the top cover light-weight design of high machine locomotive or motor train unit.
