Intelligent pipeline traction pure permanent magnet self-stabilizing maglev train

Abstract

An intelligent pipeline traction pure permanent magnet self-stabilizing maglev train comprises a viaduct square pipe channel, a pure permanent magnet self-stabilizing guiding maglev mechanism, a vertical two-in-one power supply traction mechanism and a pipeline braking mechanism. The viaduct square tube channel is not only a traction channel of a maglev train, but also a bridge of the viaduct; a square tube channel of the viaduct surrounds the pure permanent magnet self-stabilizing guide magnetic suspension mechanism, so that the magnetic suspension train does not have a derailment fault; when the height of the horizontal magnetic field air gap of the magnetic suspension mechanism is changed, the distance between the vertical magnetic field air gaps of the vertical two-in-one power supply traction mechanism is kept unchanged; the lower planes of the left permanent magnetic suspension long rotor and the right permanent magnetic suspension long rotor repel the upper planes of the left permanent magnetic suspension track and the right permanent magnetic suspension track in the same polarity, so that the maglev train is automatically kept in a permanent magnetic suspension state, and the gravity centers of a plurality of carriages of the maglev train are supported by the long pipeline bogie; the non-contact power supply traction mechanism meets traction power utilization, control power utilization and compartment service power utilization of the maglev train.

Description

technical field [0001] The invention relates to a maglev train technology, specifically, an intelligent pipeline traction pure permanent magnet self-stabilizing maglev train. Background technique [0002] At present, the technical status of modern high-speed trains is: although the speed of the train has increased, the frictional resistance of the wheel and rail has increased, and the power consumption has increased, and the speed and energy consumption have reached the limit; It is not only necessary to increase the speed, but also to save energy and reduce consumption; therefore, the existing high-speed rail train system must be upgraded with high-tech rail transit to achieve energy saving and consumption reduction. Maglev trains have no frictional resistance, which is the development direction of future rail transportation; at present, various maglev train systems and high-temperature superconducting maglev train systems in China are undergoing preliminary tests and appli...

In recent years, Southwest Jiaotong University has developed a "new type of rare earth permanent magnet maglev rail transit system", and built the world's first full permanent magnet manned test line (Hongrail) in the golden campus of Jiangxi University of Science and Technology. According to the demonstration of Jiangxi University of Science and Technology The picture shows that this is a hoisting and suspended aerial bicycle. The magnetic levitation mechanism of the (rainbow rail) adopts the full permanent magnetic levitation method in which permanent magnets are oppositely repelled. China's unique rare earth resources expand the application of magnetic materials; however (rainbow rail) still has the following defects: in order to ensure the safety of the hoisting suspension structure, the load capacity of the hoisting suspension type (rainbow rail) in the air cannot be large, and the speed of the vehicle cannot be high. Moreover, the requirements for the support strength of the column are high; the power supply system of (Rainbow Rail) relies on conventional trolley wires for power supply, and the reliability of power supply is poor; , the guide wheel has contact pressure that changes with the load, and there is a certain wheel-rail resistance; the (rain rail) permanent magnet linear synchronous motor relies on the commonly used horizontal plane linear traction method, which results in the (rain rail) magnetic levitation mechanism and Complex bogie mechanism
