Abstract

The invention relates to steering technology, in particular to a mechanical switch and a steering method applied to a high-temperature superconducting magnetic levitation system. The mechanical turnout includes: a steering magnetic track assembly, the steering magnetic track assembly includes: more than one steering magnetic track, the width of the steering magnetic track is equal to that of the permanent magnet track, each steering magnetic track is fixed on the corresponding transmission plate, and is in the transmission Above the plate, the transmission plate is connected with a drive assembly, and the drive assembly drives the transmission plate to translate, rotate, and / or lift. The invention adopts the mechanical driving force to drive the switch magnetic rail, and the magnetic field of the track after docking is uniform, and the electromagnetic resistance of operation is reduced. Moreover, the mechanical drive has more reliable performance and better magnetic field uniformity than some electromagnetic switches.

Description

technical field [0001] The invention relates to steering technology, in particular to a mechanical switch and a steering method applied to a high-temperature superconducting magnetic levitation system. Background technique [0002] figure 1 It is a schematic diagram of the structure of a high-temperature superconducting maglev train. The train body 1 relies on the interaction force between the permanent magnet track and the superconductor 2 to achieve levitation. The permanent magnetic track 3 is mainly composed of fragile permanent magnetic materials, so the reversing of the high-temperature superconducting maglev train cannot be realized by the deformation of the track like the conventional track system. [0003] Turnout is an indispensable equipment for rail transit to realize line conversion. At present, there are few studies on the turnout equipment of HTS maglev trains, and so far only a small amount of research involves HTS maglev turnouts. The currently proposed h...
