Abstract

The invention provides a vibration attenuation type magnetic levitation system track expansion adjusting structure, so that the traveling problem caused by temperature difference expansion deformationand end beam deformation of a large-span bridge is effectively solved, and vibration of the magnetic levitation system track expansion adjusting structure is reduced. The structure comprises a trackpanel located on a bridge beam body, at least two lines of longitudinal guide grooves are transversely formed at intervals in the bridge beam body below the track panel, each line of the longitudinalguide grooves is composed of longitudinal guide groove units longitudinally formed at intervals, and two transverse side walls of each longitudinal guide groove unit are provided with longitudinally-extending vertical limiting grooves. Each elastic rolling wheel installed on an installation seat through a telescopic shaft is arranged in the corresponding longitudinal guide groove unit, the two ends of each telescopic shaft extend into the vertical limiting grooves on the same side, and each installation seat is fixedly connected with the track panel.

Description

technical field [0001] The invention relates to a rail transit system, in particular to a rail telescopic adjustment structure for a vibration-absorbing maglev system. Background technique [0002] The medium and low-speed maglev rail transit adopts the suspension and guidance technology of the constant electromagnet suction type, and realizes the suspension and guidance of the vehicle through the electromagnetic attraction between the U-shaped electromagnet on the vehicle suspension frame and the F-shaped rail. At present, the medium and low speed maglev track structure that has been applied in China mainly adopts the steel sleeper type. The track is mainly composed of induction plates, F rails, expansion joints, connectors and fasteners, H-shaped steel sleepers, fastener systems, and ballast beds from top to bottom. It is composed of other parts, and is paved as a whole with the rail row as a unit. F rails, steel sleepers and induction plates are assembled into rail rows ...
