Abstract

The utility model discloses a single-toe elastic strip buckling-pressing type magnetic levitation fastener system, and aims to simplify the structure of the fastener system, improve the adjustment convenience of a fastener, effectively improve the construction efficiency and reduce the maintenance cost. The single-toe elastic strip buckling-pressing type magnetic levitation fastener system comprises an e-shaped elastic strip, an iron base plate and an L-shaped gauge block; long circular holes are formed in the two transverse sides of the iron base plate, two bosses which are transversely arranged in a spaced mode are arranged on the plate face, elastic strip installation holes are formed in the bosses, and the iron base plate is fixedly installed on a rail bearing table through T-shaped bolts with the lower portions pre-buried and fixed in rail bearing table concrete; the rail bottom of an H-shaped sleeper is located between the bosses on the two sides of the iron base plate, the L-shaped gauge block is arranged between the bosses and the rail bottom and attached to the top face and the side face of the rail bottom, the rear side limb of the e-shaped elastic strip is inserted intothe elastic strip installation holes, and a front side limb acts on the top of the L-shaped gauge block in a buckling mode.

Description

technical field [0001] The invention relates to the technical field of magnetic levitation rails, in particular to a magnetic levitation fastener system with snap-on single-toe elastic strips. Background technique [0002] Medium and low-speed maglev transportation has the advantages of environmental protection, high safety, strong climbing ability, small turning radius, low noise and strong line adaptability. It is a green rail transit system suitable for urban areas and tourist attractions. [0003] The fastener system is an important part of the track structure. The rail row and the rail platform are connected through the fastener system to ensure the stability and reliability of the track. At the same time, it can also provide elasticity for the track. The adjustment to the precision is also realized by the fastener system. Therefore, the fastener system is one of the key structures of medium and low speed maglev rail transit. [0004] At present, the fastener systems ...
