Description
Technical field
The utility model relates to Rail Transit System, particularly low speed magnetic floating traffic system rail telescopic adjustment structure in one.
Background technology
Middle low speed magnetic floating track traffic adopts the attractive suspension of normal conducting magnetic iron and guiding technique, by the electromagnetic attraction between U-shaped electromagnet and F shaped steel rail on vehicle suspension frame, realizes suspension and the guiding of vehicle.The middle low speed magnetic floating track structure of domestic existing application at present, the main steel tie pattern that adopts, track is mainly made up of parts such as tablet, F rail, expansion coupling, connector and securing member, H shaped steel sleeper, fastener system, railway roadbeds from top to bottom, mats formation taking the section of track as whole unit.F rail, steel tie and tablet are assembled into the section of track in factory or Assembling base, and the section of track couples together by F rail joint design at the scene, vertical, horizontal to neutralizing longitudinally enough temperature difference telescopic displacement regulated quantitys to ensure track.The design of F rail joint design need take into full account the convenience of the characteristic of expanding with heat and contract with cold, rail smooth requirement, train stability sexual demand and the operation maintenance of magnetic levitation track, and bonding strength, stability and the reliability of F rail joint design is train safe, key steady and that move fast.
In consideration, Low-speed maglev vehicle suspension control system feature and vehicle driving need, and the design of two sections of F rail rail gap sizes is restricted.In city city-building industry standard CJ/T413-2012 " middle low speed magnetic floating traffic section of track general technical specifications ", I type, II type and three kinds of F rail joints of III type are defined, but the rail gap stroke that it can bear is also limited, rail gap stroke excursion is only 10mm～40mm.Existing joint design is the rail gap stroke that adapts to passively two sections of F rails, can not fundamentally carry out active adjustment to rail gap stroke.Excessive rail gap stroke, can not meet vehicle driving demand, can not in the structure of existing F rail joint, realize.
Domestic and international multiple mechanism has all launched the design and researchp of middle low speed magnetic floating track structure, in the majority with Japan and Chinese research mechanism, but because the bridge span adopting is at present less, and beam type is generally simply supported beam or little span concrete continuous beam, research for the dilatation adjuster of middle low speed magnetic floating traffic route middle orbit does not also obtain enough attention, in domestic and international published technical data up to now, not yet there is the relevant middle lower speed transportation systems rail telescopic adjuster device that is suitable for using on long span bridge of introducing.Along with middle low speed magnetic floating traffic as a kind of new city system of rail traffic in big and medium-sized cities and the popularization gradually of tourist attraction, will be in the face of the situation of varied leap river valley and city major road, therefore, in Longspan Bridge situation, the design and researchp of middle low speed magnetic floating rail telescopic deformation adjustment is just extremely necessary.
At home in the existing track structure that has dropped into actual tests line or operation line, because of bridge span less, the dilatation amount producing because of the temperature difference of bridge and track is also little, substantially can be controlled in 40mm, this,, for vehicle suspension control system and rail joint design, can adapt to this deformation quantity.But, in the time that bridge span increases, variations in temperature will cause the retractable variable of larger bridge, within the scope of design temperature deformation quantity can reach 200mm and more than, continue to use the track restrained mode that the current middle low speed magnetic floating section of track is fixed in bridge beam body, is adopted between the adjacent section of track general F rail joint to connect by fastener if continue, in line design, will strictly limit bridge span, in impact, the system suitability of low speed magnetic floating traffic on long span bridge, is unfavorable for applying of middle low speed magnetic floating technology.
