Description
Technical field
The utility model relates to track traffic, particularly low speed magnetic floating traffic monolithic railway roadbed track structure in one.
Background technology
Middle low speed magnetic floating traffic adopts and often leads, electromagnetic suspension mode EMS(Electromagnetic Suspension System, electromagnetic attraction suspends), electromagnet cross recovering forces guiding, short stator linear induction motor LIM(Liner Induction Motor, line inductance electromotor) and the technology of train type of drive, the "T"-shaped guide rail of train encircling type, be a kind of novel rail solution of green low-carbon, design at present highest running speed generally at 80～150km/h.Current, middle low speed magnetic floating traffic is just with the many unique advantages of himself, and at home and abroad urban track traffic field is in the ascendant.
Different from conventional wheel rail system, track is the part closely related and the most crucial with maglev vehicle in middle low speed magnetic floating railway traffic engineering, as the ground fixed structure of supporting and guiding train operation, it is the organic component of the most crucial suspension guiding of middle low speed magnetic floating system and control system, traction and brakes.The aspects such as middle low speed magnetic floating track structure pattern, functional localization, material behavior and system accuracy all require car-magnetic good between vehicle-rail coupled relation to coordinate, and should take into full account its easy construction, high reliability and maintenanceability, with speed safety, the operation steadily, efficiently and incessantly in accordance with regulations of low-speed maglev train in guaranteeing.
For improving constantly magnetic levitation track compliance, scientific research personnel has done a large amount of research, in the patent documentation of Japan Patent JP10-46503, JP2001-115405A, JP2004-346733A and patent publication No. CN101063287A, CN2869102Y, CN102787537A, has all proposed different solutions.
Different according to system composition, at present, middle low speed magnetic floating track structure mainly contains two kinds of track structure patterns as described below:
One, adopt the multiple layer combination structure that is similar to conventional rails structure, track structure is mainly comprised of multi-parts such as tablet, F type guide rail, steel tie, independent track and corresponding connector and securing members.JP10-46503 and CN101063287A have described such structure.For example, Japan Patent JP10-46503 discloses a kind of " the anti vibration track supporting construction of the floating traveling vehicle of magnetic ": tablet is fixed on F shaped steel rail top base, wherein sleeper is the long sleeper of i iron, on sleeper, both sides are bolted F shaped steel rail, sleeper bottom is connected with two of left and right track respectively by fastener, track is cast in rail beam end face, is coupled as one with rail beam.Its main effect is to arrange vibration isolation material between sleeper and track, for absorbing structure vibration and noise and minimizing percussion.There is the deficiency of following several directions in this structure: between (1) rail, sleeper, track and rail beam, multiple layer combination, many places connect, track structure globality is poor, be unfavorable for keeping the long-term high accuracy of the section of track and high stability, track overall failure rate increases; (2) along the sleeper of arranging of consecutive intervals on line direction rail beam face, railway roadbed is Open architecture, has brought difficulty to regular maintenance and in emergency circumstances passenger's the evacuation of circuit; (3) sleeper adopts steel work, and the part magnetic line of force in the closed magnetic circuit forming between the electromagnet on suspension rack and F shaped steel rail can pass through steel sleeper, and the magnetic line of force is dispersed, and affects vehicle suspension characteristic; (4) section of track being comprised of F shaped steel rail, steel tie, tablet etc. is an overall structure, the lower fastener of pillow is almost unique supplier of track elasticity and adjustment capability, fastener is arranged on sleeper bottom can only be take the section of track as the integrally-regulated precision of unit, fundamentally determined that the accurate ride comfort of independence that cannot realize for each fastener Nodes F shaped steel rail level regulates, be track paving frame stage or later maintenance stage all to have such problem, be difficult to reach the high-precision requirement of middle Low-speed maglev vehicle for rail system.
Chinese patent CN101063287A discloses a kind of track structure and manufacture method thereof of magnetic floating traffic, compared with JP10-46503, its main distinction is that by long i iron sleeper replacement be the independent short sleepers in both sides, provides rail beam middle top surface to can be used as walkway.This structure exists globality poor and be difficult to guarantee track sufficient intensity, bending stiffness and torsional stiffness, and left and right sides F shaped steel rail or one-sided F shaped steel rail all more difficult unification or separate connection become the section of track, are not easy to the deficiencies such as construction.
Two, adopt composite orbit girder construction, sleeper is not set, F shaped steel rail function area part and beam body are separately made, and during track construction, link together.Japan Patent JP2001-115405A, JP2004-346733A and Chinese patent CN2869102Y, CN102787537A have described this structure.The patent documentation and the Japan Patent JP2004-346733A that at publication number, are CN2869102Y, CN102787537A all disclose a kind of magnetic-levitation train track, comprise rail beam, suspension rail and tablet, functional areas connector, track function district part is directly connected in rail beam side by connector, and three's difference is mainly the form of structure difference of connector.Its beneficial effect is: removed steel tie, the magnetic line of force can not be leaked on steel sleeper, Suspension power and the ability of magnetic-levitation train have been improved, rail beam upper surface is smooth noiseless, be convenient at Emergency time as passenger evacuation passage, the trajectory accuracy that independently concrete Nodes is convenient to realize in track function district regulates.But also there is the deficiency of following several respects: (1), because the function area part discord beam bodily form is integral, therefore can not form a structure that entirety is stressed, is unfavorable for guaranteeing the long-term high ride of track and track component long-term effectiveness and integrality; (2) 3 in Curve Segment circuit superelevation must or be reversed and realize by Rotation of beam, and this just need to adopt different template manufactures to have the rail beam of different sweeps or curvilinear motion rate, and requirement and the complexity of rail beam manufacture improve greatly, and economy is poor.
