Description
Technical field
The utility model relates to a kind of technology of track traffic, particularly low speed magnetic suspension beam in a kind of prefabricated reinforced concrete.
Background technology
At present, known magnetic levitation technology is proposed by German engineer's Herman. Ken Peier the earliest, and has applied for magnetic suspension train patent in 1934.Nineteen thirty-five has made magnetic and has floated test model, confirms the correctness of magnetic levitation track traffic principle.After 20 century 70s, the needs promoted traffic capacity requirement along with economic development, the developed countries such as Germany, Japan, the U.S., Canada, France, Britain start to develop conductivity magnetic levitation transport system in succession, achieve the progress attracted people's attention.
It is the technical research of superconduction repulsion aerotrain that current world magnetic suspension train technology mainly contains three kinds: one, and with Japanese MAGLEV for representative, speed can reach more than 500km/h, is mainly used in intercity long distance fast transportation; Two is that normal conductive magnetism attracts floating type train technical, between the high speed city being representative with Thyssen company's T ANSRAPID, rail vehicle transportation system (adopts long stator type linear synchronous generator to drive, speed is about 430km/h), with the HSST of Japanese ITOCHU corporate agent for rail vehicle transportation system in low speed city in representative (drive with short stator type line inductance electromotor, speed is about 100km/h); The magplane that three is normal conductive magnetism repulsion type suspension systems develops with Ci Fu aircraft manufacturing company of the U.S. is for representative, and speed is 100-150km/h, adopts linear synchronous generator to drive, but does not test through the actual motion of test wire.
Magnetic levitation track girder is the carrier of magnetic suspension train, and tablet is arranged on the lower edge in box-structure rail beam both sides or T-shaped beam beam face by German high-speed maglev train.Tablet is arranged on the both sides of U-shaped beam by Japan's high-speed maglev train, requires the rail beam accuracy of manufacture≤5mm.Although the shape of high-speed maglev train beam is different, beam has very strong restraint forces to magnetic suspension train.Magnetcisuspension Fuliang is pretensioning prestressed concrete structure.
The research of China's magnetic suspension train from the eighties in 20th century.In December, 1989, the National University of Defense technology develops China's First small size magnetic suspension theory sample car.Within 1992, in " eight or five " state key Program for Tackling Key Problems is listed magnetic suspension train key technology research by country.Nineteen ninety-five, the National University of Defense technology becomes 1 magnetic bogie with Zhuzhou Electric Locomotive Institute cooperation research and development, achieves the manned operation of full-scale single bogie first.In August calendar year 2001, the China jointly developed by Southwest Jiaotong University, Changchun Passenger Train Plant and Zhuzhou Electric Locomotive Institute first magnetic levitation passenger train is completed in Changchun Passenger Train Plant and rolls off the production line.In July, 2005, the medium-and low-speed maglev train through engineering approaches sample car CMS-03A of University of Science and Technology for National Defence's design rolls off the production line in Tangshan Locomotives & Cars Plant.In year January March to 2003 calendar year 2001, the first in the world bar magnetic suspension business transport line being cooperated to build by Sino-German two countries completes construction, and design highest running speed is 430 kilometers per hour.In January, 2012, Chinese South car Zhuzhou Electric Locomotive Co produces First Chinese platform medium-and low-speed maglev train, the highest operation speed per hour 100 kilometers, every train maximum passenger capacity about 600 people.The test of locomotive is completed subsequently on its test wire.
The middle low speed magnetic suspension train min. turning radius of China's design only has 50 meters, climbing capacity can reach 41 ‰, be well suited for using in urban track traffic, train runs on rail beam, and tablet and rail beam are in same plane, during parking, train sinks Yu Liangmian, during operation, train levitation height is 8mm ~ 12mm, and therefore, the beam accuracy of manufacture and tablet installation accuracy require all very high, if there is uneven settlement of foundation, detrimental effects can be caused to the operation of train.Be the magnetic-levitation that a kind of tablet is arranged on above beam disclosed in the utility model, the outward appearance of beam is rectangle, and inside is hollow, is steel concrete post-stress structure, and every sheet beam is a track, and two panels each other tie-beam forms a round circuit.To be beam the be monolithic construction of its advantage, two panels parallel girder delay-pour joint after erection, construction, erection load are lighter.Beam body is designed by post-stress, 25m across Liang Jing live amount of deflection≤L/6500, for steady, safety, Effec-tive Function provide condition.Beam face is floated tablet structure with magnetic and is separated, and the sliding friction of not stopping and producing is not born in beam face, improves the application life of beam.The ride comfort of track can be adjusted by the setting height(from bottom) of steel tie, occurs that uneven settlement of foundation or tablet are convenient to rapid-maintenance after breaking down.
