Background

The magnetic suspension traffic system is a novel ground passenger traffic system, and is obviously different from the traditional wheel-rail traffic system in that a vehicle body is suspended above a track by virtue of suspension force, and a walking part of the vehicle body is not in contact with the track. The propulsion generated by the linear induction motor travels on the track. The electrified suspension electromagnet on the suspension frame of the normally-conducting high-speed maglev train and the long stator coil on the track mutually attract each other to provide suspension force for the train, suck the train upwards, and ensure a stable suspension gap by controlling suspension exciting current. The suspension clearance between the electromagnet and the track is generally controlled to be 8-12 mm.

The electrified guide electromagnet on the suspension frame interacts with the guide plate on the side surface of the track to provide a guide force, so that a certain lateral distance is kept between the vehicle body and the track, and the non-contact guide in the horizontal direction is realized. The high-speed maglev train is driven by a non-vehicle-mounted power device, namely a long stator Linear Synchronous Motor (LSM), a suspension electromagnet coil is arranged at the lower part of a vehicle suspension frame, a long stator coil is arranged on a track, and when the long stator coil arranged along the line direction provides three-phase frequency modulation and amplitude modulation power, the train is pushed to advance under the action of electromagnetic induction, so that the complete non-contact traction and braking of the train in a suspension state are realized.

At present, the normal-conducting high-speed magnetic suspension traffic adopts a track beam structure form that a bridge and a track functional part are integrated, and the track functional part is arranged at two cantilever end parts (as shown in figure 1) of a beam part structure top plate of the bridge to form a track beam. Patent document CN1715561A discloses a high-speed magnetic levitation superposed type track beam connection mechanism, a track beam and a manufacturing method thereof, which comprises a support steel beam and a welding nail, wherein the connection mechanism is provided with a reinforced concrete grouting fixed connection part which is positioned in the middle part of a track plate and is used for processing the track plate and the bearing main beam to be connected into a whole, the support steel beam is H-shaped and is respectively embedded and positioned at two ends of the track plate by the welding nail, and the support steel beam is supported between the track plate and the bearing main beam. In addition, there is also the structural style that the roof that slides, magnetism deflector and the stator core of track function spare are directly pre-buried in concrete beam form the track roof beam, but the foundation all is the structural system that track function spare and bridge beam portion structure unite two into one, and it has following not enough:

(3) During the operation of the high-speed magnetic suspension traffic, after the rail surface changes due to settlement, concrete shrinkage and creep and the like, the rail surface elevation can be adjusted only through the support of the beam part structure, and no other method is used for adjusting the rail surface elevation. When the rail surface elevation is adjusted through the support, the rail surface elevation is adjusted after the whole rail beam is jacked up by the jack, time and labor are wasted, and the linear maintenance of the rail is inconvenient.
