The guide rail mechanism comprises a permanent magnet contraposition combination formed by a plurality of permanent magnets and a permanent magnet guiding combination formed by a plurality of permanent magnets. The guide rail mechanism is characterized in that the permanent magnet contraposition combination produces high magnetic pressure by utilizing mutual repulsion effect among poles of various permanent magnets, the permanent magnet guiding combination guides and diffuses magnetic energy of the permanent magnet contraposition combination and the permanent magnet guiding combination to an upper surface and an upper area of a permanent magnet guide rail for the using of high-temperature superconductive bulks by utilizing magnetization directivity of the permanent magnets. By the aid of the high-efficient permanent magnet gathering type guide rail mechanism, a shortage of low magnetic energy utilization efficiency caused by using ferromagnetic materials to guide magnetic path by an existing permanent magnet guide rail mechanism for the high-temperature superconductive maglev system is overcome, on the basis of magnetic field indexes guaranteed to meet the requirements of the maglev system, utilization efficiency of energy storage of the permanent magnet guide rail can be effectively improved, and meanwhile, the high-efficient permanent magnet gathering type guide rail mechanism is favorable for enhancing the overall performance of the high-temperature superconductive maglev system from aspects of magnetic field construction and magnetic energy distribution.
