Description
Technical Field

Background
With the development of national economy in China, people have higher and higher requirements on travel quality, and more popular traffic modes with higher speed and more comfort are more and more popular. The high-speed railway train with the current design speed of 350km/h is difficult to greatly improve in the running speed due to the influence of factors such as wheel track relation, running environment and the like. Therefore, magnetic levitation track traffic having a higher speed than a wheel track high speed train is becoming an important development in the future. The magnetic suspension traffic system is a track traffic system adopting non-contact electromagnetic suspension, guiding and driving, has no wheels of the traditional wheeltrack vehicle, and stably suspends the vehicle by generating strong electromagnetic attraction or repulsion force through an active suspension control system and provides traction force by utilizing a linear induction motor. At present, the levitation gap of the magnetic levitation train is only about 10mm, and the speed is high, so that the magnetic levitation transportation system has higher requirement on track alignment. When a bridge structure supporting the magnetic levitation train is subjected to sedimentation or transverse displacement, the track smoothness of the magnetic levitation train is affected, and when the track smoothness is out of tolerance, the vehicle cannot suspend and track breakage occurs. Therefore, the magnetic suspension rail transit bridge support also has the functions of heightening, transverse position adjustment and the like on the basis of the functions of the common bridge support.
At present, the support is mainly provided with four heightening modes of backing plate heightening, wedge heightening, filling heightening and spiral heightening. The height-adjusting mode of the base plate cannot be used for stepless height adjustment, the height-adjusting precision is poor, and the height-adjusting base plate is not easy to install due to the small space of the beam bottom. The wedge inclination in the wedge heightening process cannot be too large, the heightening amount is limited, and the wedge heightening machine is not suitable for occasions with large heightening height. After the filling height-adjusting mode is adopted, the filling height-adjusting mode is generally adopted only once due to the blockage of a pipeline. Screw heightening is carried by threads, and a screw heightening support which is commonly used at present is easily influenced by rotation of a support upper structure, so that the stress condition of threads is poor. In addition, the height-adjusting support does not have a transverse positioning function, and is difficult to meet the requirements of magnetic suspension rail transit on bridge supports.
