Abstract
The utility model discloses a medium and low speed magnetic levitation train rail, and the rail (3) is directly fixed at the two sides of the girder (4) by bolt or in a pre-embedded method; a reverse U-shape suspension rail (1) or the rail (3) at the lower part is fixed at the lower surface of the rail (3) by a bolt to form a reverse U-shape suspension rail (1). The rail is high in rigidity so that the magnetic levitation train is running more stably and reliably; and the rail is simple in structure, convenient for modularizing production and manufacture in the factory, and can be mounted, debugged and maintained on the spot.
Description
Affiliated technical field
The utility model relates to a kind of middle low-speed maglev train track.
Background technology
The magnetic-levitation train of middle low speed electromagnetic attraction type short stator Induction Motor-Driven, the track structure that uses as shown in Figure 3 at present: it comprises the sleeper that beam and beam upper bolt connect, both sides connect F shaped steel rail by bolt on the sleeper, it is the inverted U suspension rail that F shaped steel rail stretches out rail bottom partly, and the rail upper surface is settled the motor reaction plate.This structure has the following disadvantages:
One, all links to each other between rail, sleeper and the beam in the bolt mode.In working environment, the easy loose or dislocation of bolt increases the fault rate of track integral body; Two, since between rail and the sleeper bolt is connected, so the rigidity of rail is little, is easy to produce skew and vibrates, and influences the stability of magnetically supported vehicle; Three, the rail owing to both sides is to fix in bolted mode, adds to be difficult to man-hour guarantee its magnetic pole strength at grade, causes the inclination of magnetic suspension car body, not steady; Four, rail and sleeper are steel work, and the part magnetic line of force in the closed magnetic circuit that forms between electromagnet on the magnetically supported vehicle and rail can pass through steel sleeper, and the magnetic line of force is disperseed, and influences the pull characteristics of magnetically supported vehicle; Five, sleeper that be interrupted to install of beam upper surface makes the top unevenness of track, in case emergency takes place, from the passenger to the track under the car body rear and front end, is subjected to the restriction of gap sleeper, runs, flees from difficulty; Six, a plurality of members such as rail, sleeper, beam are arranged, high for guaranteeing the stable operation of magnetically supported vehicle to the processing and the installation accuracy requirement of these members, brought the difficulty of production, installation, debugging and maintenance.Seven, F shaped steel rail is connected on the sleeper by the bolt mode, and its load that bears is limited, and its width that stretches out the sleeper part is restricted, and the width of the motor reaction plate of its upper surface also is restricted, and power of motor will be restricted.
Therefore, the magnetic-levitation train track of the middle low speed electromagnetic attraction type short stator Induction Motor-Driven of existing structure does not meet the performance requirement of maglev train system, and the rigidity of rail beam is difficult to guarantee and the requirement on machining accuracy height that installation difficulty is big, debugging, difficult in maintenance.
Summary of the invention
The purpose of this utility model just provide a kind of in the low-speed maglev train track, the precision height of this kind track, integral rigidity is strong, makes the operation of magnetically supported vehicle more stable, reliable; And it is simple in structure, and it is strong to be convenient to factory's integral rigidity, makes the operation of magnetically supported vehicle more stable, reliable; And it is simple in structure, be convenient to factory's modularization and manufacture, and on-the-spot the installation, debugging and maintenance are easily.
The utility model solves its technical problem, the technical scheme that is adopted is: low-speed maglev train track in a kind of, comprise the motor reaction plate of beam, rail and rail upper surface, its design feature is: rail directly is fixed on the both sides of beam by bolt or pre-buried mode; The soffit of rail fixedly is inverted U in the bottom of inverted U suspension rail or rail in the bolt mode, constitutes the inverted U suspension rail.
Compared with prior art, the beneficial effect of the technical solution of the utility model is:
Rail is directly installed on the both sides of beam, has saved original sleeper, has reduced the bolt connecting link, and the integral rigidity of track increases, and the stability of magnetically supported vehicle is improved; Beam and rail can wholely in special-purpose factory be processed, make, and do not need to install at the construction field (site), have improved installation accuracy, and the magnetic pole strength that rail produced of assurance the right and left makes the operation of magnetically supported vehicle more steady at grade; Removed steel tie, the magnetic line of force can not leak on the steel tie, has improved the suction of magnetic suspension train; Simultaneously the upper surface of track no longer includes and is interrupted the sleeper of installing, and makes track upper surface smooth, is convenient at the critical moment, runs, flees from from the passenger to the track under the car body rear and front end.Rail is pre-buried or directly be fixed on the beam in the bolt mode, and its load that bears increases greatly, and the width that makes rail stretch out the beam part increases, and the width of the motor reaction plate of its upper surface no longer is restricted, and power of motor is improved.
Above-mentioned rail is I shape rail or box rail.Adopt existing a large amount of I shape rail or box rail that uses, can reduce cost, and realize easily being connected with the firm of beam.
The utility model will be further described below in conjunction with the drawings and specific embodiments.
