Description

Technical Field

[0001] This utility model relates to the technical field of safety devices for maglev trains, and more specifically, to an anti-slip device for maglev trains. Background Technology

[0002] A maglev train is a type of train propelled by magnetic levitation. It uses electromagnetic force to achieve contactless levitation and guidance between the train and the track, and then uses electromagnetic force generated by a linear motor to pull the train. Because the magnetic force of its track levitates it in the air, friction is reduced. Unlike other trains that need to contact the ground, it is only subject to air resistance. High-speed maglev trains can reach speeds of over 400 kilometers per hour.

[0003] A search revealed an automatic anti-suspension permanent magnet-electromagnetic hybrid levitation device with announcement number CN214831553U. Pure permanent magnet levitation modules and pure electromagnetic levitation modules are arranged longitudinally below the track. Under normal operating conditions, the magnetic field polarities on both sides of the pure permanent magnet and pure electromagnetic levitation modules are the same. Therefore, the pure permanent magnet and pure electromagnetic levitation modules together provide an upward levitation force to the maglev train, and the combined levitation force is greater than the weight of the maglev train, keeping it suspended. However, when the maglev train is not operating normally, the pure electromagnetic levitation modules generate a weaker or no magnetic field. The levitation force generated by multiple pure permanent magnet levitation modules is less than the weight of the maglev train. When the levitation force on the maglev train decreases, it can fall under its own weight, thus preventing the maglev train from being attracted to the track.

[0004] When a maglev train is in motion, its track lacks external support structures. Due to the train's own weight and the magnetic attraction of the track surface, the train's height is prone to fluctuations, causing it to come into contact with the track and become stuck. This poses a significant safety hazard. Therefore, we have proposed an anti-sticking device for maglev trains to address the aforementioned problems. Utility Model Content

The maglev train travels directionally along the maglev track. During travel, the guide wheel rotates at high speed under the aerodynamic force of the area where the maglev train travels. When the maglev train experiences height fluctuations, the guide wheel provides excellent isolation, auxiliary support, and guidance, thus achieving a good anti-slip protection effect and improving driving safety. A drainage groove is provided at the bottom of the support plate, and the drainage groove and groove are interconnected to facilitate the drainage of rainwater and keep the working area of ​​the guide wheel dry.
