Description
Technical field
The utility model belongs to field of railway transportation equipment, relates to a kind of enhancing pantograph composite carbon slide plate of carbon fiber veneer, is specifically related to a kind of enhancing pantograph composite carbon slide plate of the carbon fiber veneer for electric locomotive and EMU.
Background technology
Along with Fast Construction and the development of China Express Railway, the construction of EMU is also in continuous quickening, and just the quantity of the EMU of China arranges close to 1000 so far, and the quantity of EMU is also in continuous increase.
The operation power resources of electric locomotive and EMU are in the contact line conducting wire of frame at EMU top, synchronously slided with the top line pressure of 6 ~ 8kg and Wire stick close contact and motor train unit by the pantograph carbon slide that is installed on EMU roof top, high tension supply in contact system is transferred to electric locomotive and the running of motor train unit high-speed electric expreess locomotive, drive EMU high-speed cruising.So the pantograph carbon slide being installed on EMU top be guarantee its EMU at a high speed, one of safe operation very important critical component, be also classified as vitals by Chinese Railway main office.This pantograph carbon slide all relies on German imported with original packaging product at present, and imported product delivery cycle is long, and expensive.
Existing electric locomotive and EMU pantograph carbon slide are by carbon bar and strip aluminium bracket conductive adhesive gained.The high-speed electric expreess locomotive making carbon top and conductive contact high tension supply is sent to locomotive or motor-car by carbon bar top and high-voltage fence wire with the top line pressure of 6 ~ 8kg when real-world operation operates, thus drive electric locomotive and EMU operation.Carbon slipper conduction while also will be same with electric locomotive or EMU speed sliding with wire.Because the connection of whole carbon bar is only by conducting resinl, carbon material is all fragility, runs into impact and will rupture and fall block.Electric locomotive and EMU operationally often can run into the node and suspension clamp etc. of wire because of climate change; the factors such as strong wind occur that displacement and dislocation form hard spot; thus cause carbon bar when high-speed slide, carbon slipper interrupted or destroy block; some is even beaten carbon bar and flies; only remaining aluminium cradle surface will cause serious traffic safety accident, and this situation also can be blown electrical network and caused cataphoretic failure and consequence.Moreover carbon bar and aluminium bracket are only by conductive adhesive, bind strength is limited, add carbon slipper operationally due to very large by the magnitude of current, add that high-speed friction causes slide plate to generate heat, sometimes slide plate temperatures as high more than 400 is spent, at this moment conducting resinl will be caused to lose efficacy, and slide plate carbon bar fracture and come off and cause the accident.There is above such accident and all want hundreds of times every year in china railway system.Cause locomotive to stop transport and incur loss through delay and repairing, the whole nation is annual because of the more than one hundred million unit of this type of causality loss.
Utility model content
The purpose of this utility model is the above-mentioned defect for prior art, provides a kind of enhancing pantograph composite carbon slide plate of the carbon fiber veneer for electric locomotive and EMU.
The purpose of this utility model can be achieved through the following technical solutions:
A kind of electric locomotive and EMU, with strengthening pantograph composite carbon slide plate, comprise the interior tissue pantograph carbon slide agent structure, the pantograph carbon slide agent structure side that be made up ofs carbon bar and aluminium bracket be close to and permeate and have the carbon fiber mesh fabric of metal powder and be close to the alloy carbon surface layer outside carbon fiber mesh fabric.Interior tissue infiltration has the carbon fiber mesh fabric of metal powder and alloy carbon surface layer to form high connductivity alloy carbon fiber overlay coating, high connductivity alloy carbon fiber overlay coating is close to pantograph carbon slide agent structure side, identical with pantograph carbon slide agent structure side view, for multi-angle and integral curved, such shape is conducive to the carbon bar on top and the aluminum strip of bottom firmly to catch on, and makes structure more firm.
Wherein said carbon fiber mesh fabric is the carbon fiber mesh fabric of wide 45 ~ 50mm, 1 ~ 4k.
Pantograph carbon slide agent structure and high connductivity alloy carbon fiber overlay coating have one deck veneer glue-line.
Described alloy carbon surface thickness is 0.3 ~ 0.7mm, preferred 0.5mm.
Beneficial effect:
The two sides of pantograph carbon slide agent structure are mainly carried out carbon fiber high connductivity sticking veneer and are obtained a kind of enhancing pantograph composite carbon slide plate by the utility model again, this enhancing pantograph composite carbon slide plate possesses higher intensity, higher electric conductivity, stronger toughness and shock-resistant, anti-fracture and fall block performance than the carbon slipper be made up of carbon bar and aluminium bracket, and applicable more than 380kg/h speed is run.Enhancing pantograph composite carbon slide plate of the present utility model is compared with the carbon slipper of external imported with original packaging, price reduces 50%, service life increases by 50%, thus reach the object reduced costs, and meet the carbon slipper failure-free operation when 380kw/h, the generation of improper accidents such as being in operation and can not producing fracture, fall block, be burned, guarantees the safe and reliable operation of China's EMU and electric locomotive.
