Abstract

An elastic strip pressing type low and medium speed magnetic levitation traffic system track stretching adjusting structure aims to effectively solving the traffic problem caused by temperature difference stretching deformation of a large-span bridge. The elastic strip pressing type low and medium speed magnetic levitation traffic system track stretching adjusting structure comprises a rib plate type track row, track bearing tables, base plates, sleeper transverse check blocks, foundation bolt assemblies and elastic pressing strips. The track bearing tables are transversely arranged in two rows on a bridge body in a spaced mode. The base plates are arranged between the top faces of all the track bearing tables and the bottom face of a longitudinal connecting plate, and elastic strip fixing lugs transversely arranged at intervals are arranged on the top faces of the cushion plates. The cross section of the sleeper transverse check blocks is in an L shape, the sleeper transverse check blocks are reversely buckled between the elastic strip fixing lugs and the longitudinal connecting plate. The lower portions of the foundation bolt assemblies are pre-buried and fixed in the bridge body, and the upper portions of the foundation bolt assemblies penetrate through the track bearing tables and the base plates to press the elastic pressing strips tightly on the sleeper transverse check blocks and the elastic strip fixing lugs.

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...
