Abstract

The invention discloses a buckle plate type track expansion adjusting structure of a medium-low speed magnetic levitation transportation system for effectively relieving the driving problem caused by temperature difference expansion deformation of a large-span bridge. The structure comprises a rib plate type track panel, track bearing tables, cushion plates, foundation bolt components and buckle plates, wherein a main body of the rib plate type track panel consists of sleeper units longitudinally arranged at intervals, and two longitudinal connecting plates fixedly connecting the sleeper units into a whole and transversely arranged at intervals; rib plates are welded between the sleeper units and the longitudinal connecting plates; two lines of the track bearing tables are transversely arranged on a bridge body at intervals; the cushion plates are arranged between the top surfaces of the track bearing tables and the bottom surfaces of the longitudinal connecting plates; buckle plate fixing convex blocks are transversely arranged on the top surfaces of the cushion plates at intervals; the lower parts of the foundation bolt components are embedded and fixed in the bridge body; and the upper parts penetrate through the track bearing tables and the cushion plates to tightly press the buckle plates on the longitudinal connecting plates and the buckle plate fixing convex blocks.

Description

Technical field [0001] The invention relates to a rail transit system, in particular to a track expansion and contraction adjustment structure of a medium and low speed maglev transit system. Background technique [0002] The medium and low-speed maglev rail transit adopts the levitation and guidance technology of the normal conductive magnet, 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 low- and medium-speed maglev track structure that has been used 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 track beds from top to bottom. It is composed of other parts, and the rail row is used as a unit to pave the whole. F rails, steel sleepers and induction plates are assembled into rail ...
