Abstract

A track telescopic adjustment structure for a medium and low speed magnetic suspension transportation system effectively solves the driving problem caused by temperature difference telescopic deformation of a long-span bridge. The track telescopic adjustment structure comprises a rib plate type track skeleton, under-rail supporting vibration reduction bodies, and foundation bolt assemblies. The body of the rib plate track skeleton is composed of sleeper units and two longitudinal connecting plates, wherein the sleeper units are arranged in the longitudinal direction at intervals and are fixedly connected into a whole through the two longitudinal connecting plates which are transversely arranged in a spaced mode, rib plates are welded between all the sleeper units and the longitudinal connecting plates, and long groove holes extending in the longitudinal direction are formed in the longitudinal connecting plates at intervals in the longitudinal direction and the transverse direction. The under-track supporting vibration reduction bodies are arranged between the bottom face of the rib plate type skeleton and the surface of a bridge body of the bridge. The lower portions of the foundation bolt assemblies are embedded in the bridge body of the bridge, and the upper portions of the foundation bolt assemblies penetrate through the under-track supporting vibration reduction bodies and the long groove holes.

Description

technical field [0001] The invention relates to a rail transit system, in particular to a track telescopic adjustment structure for a medium-low speed maglev transportation 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 in...
