Description
Technical field
The present invention is mainly concerned with the pantagraph current collector field, refers in particular to a kind of lateral current collector that is applicable to the floating train of normal magnetic conduction.
Background technology
In the prior art, the supply of low-speed maglev train electric energy and high-speed maglev train are in the supply of the electric energy of low speed segment in often leading, the same with subway and light rail, all be the mode that adopts by three rails, the power supply of four rails, guide electric energy into magnetic-levitation train by the fluent boots that are subjected to of pantagraph current collector with the dynamic mode that is flowed that contacts of power rail then.In three rails power supplies, have three kinds to be subjected to stream mode: top is subjected to stream (being subjected to the trajectory friction to be subjected to stream interface up), bottom to be subjected to stream (being subjected to the trajectory friction to be subjected to stream interface down) and side direction to be subjected to stream (be subjected to trajectory friction be subjected to stream interface edge-on).Be subjected to stream mode for top, face up because of being subjected to trajectory, have easily and to be subjected on the trajectory face impurity such as deposition dust, aggravation is subjected to the abrasive wear of trajectory face and shoegear, causes simultaneously to draw electric arc to form erosion and wear, and big sleet easily causes shortcomings such as being flowed shakiness; Be subjected to stream mode for the bottom, installation with pantagraph current collector causes the increase of vehicle gauge, the icicle that formed by the trajectory face is bigger to steadily impacted by stream, be subjected to trajectory to give the pressure direction of shoegear opposite with the suspension direction that vehicle is subjected to, the kinematic mechanism et out of order of arbitrary pantagraph current collector all can produce the clamping stagnation effect to the floating of vehicle, cause shortcomings such as car load floating difficulty, so top and bottom are subjected to stream mode generally to be adapted to subway and light rail.If adopt side direction to be subjected to stream mode, because of being subjected to the edge-on installation of trajectory, be difficult for being subjected to save bit by bit foreign material such as dust, sleet on the trajectory friction face, the abrasive wear and the arc erosion wearing and tearing that caused by the impurity interference greatly reduce.Because of the track of magnetic-levitation train is to adopt the elevated bridge form, be subjected to the trajectory side direction to be installed on the both sides of track girder, outside being subjected to the parallel sidewalls that is flowed friction face and track girder of trajectory and facing, during work, the fluent boots that are subjected to of pantagraph current collector stretch towards the track girder direction, make the vehicle structure compactness.Simultaneously, this side direction is subjected to stream mode, can not produce the clamping stagnation effect to the vehicle floating because of the mechanism kinematic fault of pantagraph current collector, influences the normal floating of vehicle.Therefore magnetic-levitation train adopts the side direction of three rails, four rails to be subjected to stream mode to have compact conformation, safety, reliable, characteristics such as be subjected to that stream is stablized.
Aspect the patent of invention of the 3rd rail pantagraph current collector, two patents that have Yongji Motor Factory to declare: " having the pantagraph current collector that breaks away from three rail devices " (number of patent application: 200510012350.0) reach " pantagraph current collector " (number of patent application: 00261315.8).Apply for a patent for these two and belong to respectively that top is flowed and the bottom is subjected to stream mode, be only applicable to subway and light rail.
Aspect the research of magnetic-levitation train pantagraph current collector, certain research was done by domestic Southwest Jiaotong University, its research contents is described in paper " development of magnetic-levitation train pantagraph current collector " (" mechanical investigations and application " the 4th phase in 2002), what adopt also is that side direction is subjected to stream mode, its groundwork is to adopt the combination of linear bearing and spring, it is slow that its shortcoming is exactly mechanism's dynamic response, easily causes to be subjected to stream unstable, is unwell to the application of through engineering approaches.Change with train and interorbital horizontal position simultaneously, be subjected to fluent boots and changed greatly by the pressure between trajectory, be unfavorable for stable stream; Excessive pressure can increase the abrasion that are subjected to fluent boots and are subjected to trajectory, and too small pressure can cause that contact is subjected to stream unstable, and its pressure must remain in the reasonable range, and it is disadvantageous that excessive pressure changes being subjected to stream.Also having some side direction to be subjected to the swinging gear of stream mode is to adopt single pendulum mechanism, all is contacted with being subjected to the good of trajectory by fluent boots in order to compensate train and to be subjected to the change in location between trajectory and to be subjected to the wearing and tearing of fluent boots, remaining, and realization is stablized and flowed.When train along perpendicular to the direction that is subjected to the trajectory face with respect to being subjected to trajectory that parallel move and when being subjected to fluent boots wearing and tearing, swinging gear is just swung, to remedy relative shift taken place.But there is significant disadvantages in single pendulum mechanism, in the pantagraph current collector of single pendulum mechanism, swung with respect to the pantagraph current collector pedestal by fluent boots, be subjected to fluent boots and be subjected to the trajectory face to present angle, angle changes with the difference of oscillating quantity, the appearance of angle, in fact, make to be subjected to fluent boots and to be subjected between trajectory to line contacts, unfavorable to being flowed.
