Description
Technical Field

Background
With the development of national economy of China, the requirements of people on the quality of travel are higher and higher, and a higher-speed and more comfortable traffic mode is more and more popular. The method is limited by the influence of factors such as wheel-rail relationship, operation environment and the like, and the running speed of the high-speed railway train with the design speed of 350km/h at present is difficult to be greatly improved. Therefore, magnetic levitation rail transportation having higher speed than the high-speed train of wheel track becomes the development focus in the future. The magnetic suspension traffic system is a track traffic system adopting non-contact electromagnetic suspension, guidance and driving, does not have wheels of the traditional wheel-rail vehicle, generates strong electromagnetic attraction or repulsion through an active suspension control system to enable the vehicle to stably suspend, and provides traction force by using a linear induction motor. At present, the suspension gap of a magnetic suspension train is only about 10mm generally, and the magnetic suspension transportation system has higher requirement on the track line shape because of high speed. When the bridge structure supporting the maglev train sinks or laterally shifts, the track smoothness of the maglev train is affected, and when the track smoothness is out of tolerance, the vehicle cannot suspend and the track hitting phenomenon occurs. Therefore, the magnetic suspension rail transit bridge bearing has the functions of height adjustment, transverse position adjustment and the like on the basis of the functions of a common bridge bearing.
At present, the support mainly comprises four height adjusting modes, namely a base plate height adjusting mode, a wedge block height adjusting mode, a filling height adjusting mode, a spiral height adjusting mode and the like. The backing plate height-adjusting mode can not carry out stepless height adjustment, and height-adjusting precision is relatively poor to because the beam bottom space is little, height-adjusting backing plate is difficult to install. The wedge inclination in the wedge height adjustment cannot be too large, the height adjustment amount is limited, and the wedge height adjustment is not suitable for occasions with large height adjustment height. After the filling and height-adjusting mode is used for height adjustment, the height adjustment can be generally performed only once due to pipeline blockage. The screw heightening is carried by screw threads, and the screw heightening support commonly used at present is easily influenced by the rotation of the upper structure of the support, so that the stress condition of the screw threads is poor. In addition, the height-adjusting support does not have a transverse position adjusting function, and is difficult to adapt to the requirements of magnetic suspension rail traffic on bridge supports.
