Description

TECHNICAL FIELD

[0002] The statements in this section merely provide background information related to the present application and do not necessarily constitute prior art.

[0003] The principle of high-speed magnetic levitation train is to use the property of "like poles repel, opposite poles attract" of magnets to make the magnets have the ability to resist the earth's gravity, that is, "magnetic suspension"; it is used on the railway transportation system to make the train completely separate from the track and run in suspension, becoming a "wheelless" train, and its speed can reach several hundred kilometers per hour or more. Since the magnetic levitation system is suspended, guided and driven by electromagnetic force, the safety protection measures after power failure, especially the braking problem after the train is powered off, still need to be solved, and the high-speed stability and reliability still need a long time of test. The fault of high-speed magnetic levitation train generally refers to the condition that the train cannot normally levitate due to power failure or other reasons of the traction levitation system. The ramp fault is a working condition that the train slides down when the train fails to run on the ramp. Generally, the sliding speed of high-speed magnetic levitation train is slow when the ramp fails, and some measures can be taken to stop the train from sliding. SUMMARY

[0033] Embodiment one

[0034] The embodiment one of the present application introduces a slope failure electromagnetic adsorption type parking device for high-speed maglev train.

[0035] As shown in Figure 1 , Figure 2 , Figure 3 and Figure 4 , a slope failure electromagnetic adsorption type parking device for high-speed maglev train is arranged at the bottom of the two side edges in the train advancing direction, which comprises an electromagnet 1, an electromagnet core 1-1, an electromagnetic winding 1-2, a mechanical fixing mechanism 2, a mechanical connecting rod 2-1, a bearing 2-1-1, a spring 2-2, a sleeve 2-3, a mechanical hook 2-4, a mechanical lock 3, a train bottom shaft 4, a center rail 5 and a cross beam 6.

[0036] As one or more embodiments, the electromagnet 1 is a key component of the electromagnetic adsorption type parking device, which is mainly used for parking or speed reduction when the high-speed maglev train occurs slope failure and produces slope sliding. The electromagnet 1 is composed of the electromagnet core 1-1 and the electromagnetic winding 1-2; the electromagnet core 1-1 is made of silicon steel sheet, which can adopt cuboid core or cylindrical core; the electromagnetic winding 1-2 is copper wire, which is wound around the electromagnet core 1-1, and is powered by the vehicle-mounted power supply system or the storage battery, so as to realize the power absorption function of the electromagnet 1.

[0037] As one or more embodiments, the mechanical fixing mechanism 2 is fixed by the mechanical lock 3. When the high-speed maglev train appears ramp failure and generates ramp sliding, the mechanical lock 3 controls or manually controls the release of the mechanical fixing mechanism 2, so that the mechanical fixing mechanism 2 freely falls. At this time, if the electromagnet 1 cannot realize the train stopping sliding, the mechanical fixing mechanism 2 will hook the beam 6 structure on the track to realize the train stopping. The mechanical fixing mechanism 2 is composed of a mechanical connecting rod 2-1, a spring 2-2, a sleeve 2-3, a mechanical hook 2-4 and the like. The tail end of the mechanical connecting rod 2-1 is a bearing 2-1-1 structure, which is connected with the bottom rotating shaft 4 of the high-speed maglev train. The mechanical connecting rod 2-1, the spring 2-2 and the mechanical hook 2-4 are sequentially connected. The sleeve 2-3, the mechanical connecting rod 2-1 and the mechanical hook 2-4 are made of steel material, and the spring 2-2 can adopt ordinary alloy spring or hydraulic spring. The sleeve 2-3 mainly plays a role in protecting the spring.

[0038] The number of electromagnets 1 arranged at the bottom of each car is greater than or equal to 4, and the mechanical fixing mechanism 2 appears in pairs, and the number of pairs of mechanical fixing mechanisms 2 is greater than or equal to 2. The ramp failure electromagnetic adsorption type parking device of the high-speed maglev train also needs to cooperate with the track at the ramp. The middle position of the track at the ramp needs to be paved with a center track 5, so that the electromagnet 1 can be adsorbed to stop the train from sliding until it stops. In addition, the middle position of the track at the ramp also needs to be provided with a groove structure, and the beam 6 structure is arranged in the middle position of the groove, so as to ensure that the mechanical hook 2-4 can hook the beam 6 to realize the stopping of the train when the train slides due to the ramp failure. The number of groove structures needs to be cooperatively arranged with the mechanical fixing mechanism 2.

[0039] In the embodiment, the material of the electromagnet core 1-1 is silicon steel sheet, which can adopt a cuboid structure or a cylindrical structure. The electromagnetic winding 1-2 is wound around the electromagnet core 1-1, which is a copper wire structure. The lower surface of the electromagnet 1 is in the same plane as the bottom surface of the train, and is arranged at the bottom of the high-speed maglev train. The mechanical fixing mechanism 2 is arranged adjacent to the electromagnet 1, which is composed of a mechanical connecting rod 2-1, a spring 2-2, a sleeve 2-3, a mechanical hook 2-4 and the like. The mechanical connecting rod 2-1, the spring 2-2 and the mechanical hook 2-4 are sequentially connected, and the sleeve 2-3 is a steel structure and is located outside the spring 2-2 for protecting the spring 2-2 structure. The spring 2-2 is used to buffer the shock generated by the train stopping, and can be arranged as an ordinary alloy spring or a hydraulic spring. The tail end of the mechanical connecting rod 2-1 is a bearing 2-1-1 structure, which is connected to the bottom rotating shaft 4 of the train, and the mechanical connecting rod 2-1 is not fixed, so that the mechanical connecting rod 2-1 can freely rotate. In the case of ramp failure of the train, the mechanical hook 2-4 will hook the beam 6 on the track to realize the train stopping state, which is a steel structure.

[0040] The electromagnet 1 is arranged in two columns at the bottom of the train, and the number of electromagnets 1 is greater than or equal to 4. The mechanical hooks 2-4 are arranged in one column at the bottom of the train, and the number of mechanical hooks 2-4 appears in pairs, and the number of pairs of mechanical hooks 2-4 is greater than or equal to 2. The electromagnetic adsorption type parking device for the slope failure of the high-speed maglev train should be arranged in cooperation with the slope, and the track center position where the slope is located needs to be paved with a center track 5 to form an adsorption effect with the electromagnet 1 during sliding. In addition, the track center position is arranged with grooves at intervals, and a steel beam 6 is arranged at the center of the groove, which is used to cooperate with the mechanical hooks 2-4 to realize the parking state of the train.

[0041] In this embodiment, the train is stopped from sliding or the sliding speed of the train on the slope is reduced by the adsorption and friction between the electromagnet and the center track on the slope, and then the mechanical hook hooks the beam on the track to realize the parking state, thereby avoiding the damage of personnel or the train caused by the slope failure, and effectively improving the safety and reliability of the operation of the high-speed maglev train.
