Medium and low-speed maglev track with a rail-bar connection device that ensures continuous signal collection

Abstract

The invention discloses a medium-and-low-speed magnetic levitation track provided with track skeleton connecting devices capable of guaranteeing signal acquisition continuity. The track skeleton connecting devices are arranged on expansion joints between adjacent track skeletons. Each track skeleton connecting device comprises a U-shaped levitation detection surface lower connecting plate and fixing pieces, wherein through holes are formed in the two ends, in the direction of the track, of the levitation detection surface lower connecting plate correspondingly, the through hole in one end is matched with and corresponds to a connecting hole in the end of one track skeleton, and the through hole in the other end is an oblong hole with the length direction identical to the direction of the track; and the fixing piece are inserted correspondingly after the levitation detection surface lower connecting plate is mounted on the levitation detection surfaces of the opposite ends of the two corresponding adjacent track skeletons, and used for fixing the levitation detection surface lower connecting plate, and the fixing piece corresponding to the oblong hole can slide relatively in the oblong hole so as to adapt to stretching and contracting of the track skeletons. The continuity of magnetic levitation signals can be effectively guaranteed while the track completely adapts to the stretching and contracting deformation of the track skeletons in the longitudinal direction, and thus smooth and stable operating of a train is guaranteed.

Description

technical field [0001] The invention belongs to the technical field of medium and low speed maglev track structures, and in particular relates to a medium and low speed maglev track with a rail row connecting device that can ensure continuous signal collection. 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 structure of the medium and low speed maglev track mainly adopts the steel sleeper type. The track mainly includes induction plates, F-shaped steel rails (also called F rails), expansion joints, connectors and fasteners, steel sleepers, fastener systems, and bearings from top to bottom. It is composed of rail platform and other parts, and is paved as a whole ...

Problems solved by technology

However, the above-mentioned connection joints are only connected on one side of the wing plate. Although the contact and smooth operation of the traveling wheels can be guaranteed, the other side of the F rail, that is, the expansion joint between the two rail rows on the side of the induction plate, still exists.

The existence of such expansion joints will cause the suspension detection surface to be in an interrupted state at the joint of the rail row, thereby interrupting the maglev signal, and even causing abnormal signal input, affecting the stable operation of the train
