Magnetically-levitated track sleeper joint and magnetically-levitated track

Abstract

A magnetic levitation rail row connector and a magnetic levitation track provided by the present invention, the magnetic levitation rail row connector includes a main connector and a secondary connector respectively arranged on two adjacent rail rows. The concave-convex fit of the main joint and the auxiliary joint can realize the vertical and horizontal limit adjustment of the rail row. The maglev track is composed of main joint rail row and auxiliary joint rail row connected in sequence. This solution forms a magnetic pole surface without excessive gaps through the concave-convex cooperation of the main joint and the auxiliary joint, avoiding the existence of the gap end face in the past. When the external temperature changes, the rail row can freely expand with heat and contract with cold and fluctuate in position, ensuring magnetic levitation The stable operation of the train reduces energy consumption.

Description

technical field [0001] The invention belongs to the technical field of rail transit, and in particular relates to a magnetic levitation rail row joint and a magnetic levitation track. Background technique [0002] Maglev transportation is a brand-new transportation mode different from subway, light rail transportation, and monorail transportation. It has a series of characteristics such as low noise, small vibration, no pollution, strong line adaptability, and easy planning and construction. It is safe, reliable, and environmentally friendly. A new type of urban rail transit system, especially suitable for public transportation in old urban areas, commercial core areas, downtown areas, short-distance cities, and tourist attractions, and is increasingly becoming one of the ideal choices for urban rail transit systems. With the development of the rail transit industry, the objective needs of urban traffic put forward higher requirements for the technology of the maglev rail tr...

Problems solved by technology

However, in the prior art, there is a cross section at the joint connection between the rail row and the rail row, and the width of the cross section is generally about 20 mm. During the high-speed operation of the maglev train, the floating magnet is prone to appear "" when passing the cross section. The phenomenon of "flying" and the "falling" phenomenon of the supporting wheel device will cause small fluctuations in the running train, which will affect the smooth operation of the train, reduce comfort, form unsafe factors, and increase energy consumption.

[0004] In addition, since the joints between rail rows and rail rows are fastened by bolts, when the train is running, since the joints cannot provide a certain free movement gap with the bumps of the train, the force on the maglev train is uneven. Unavoidable fluctuations in train operation
