Abstract

The invention discloses a vacuum maglev pipeline structure, and belongs to the technical field of vacuum high-speed maglev traffic. The vacuum maglev pipeline structure comprises a plurality of piers and a plurality of vacuum maglev pipeline units. The multiple piers are arranged in parallel at intervals. Each vacuum magnetic levitation pipeline unit comprises a vacuum corrugated pipe and two vacuum magnetic levitation pipelines which are coaxially arranged, one end of the vacuum corrugated pipe is communicated with one end of one vacuum magnetic levitation pipeline through two sliding flanges, and the other end of the vacuum corrugated pipe is communicated with one end of the other vacuum magnetic levitation pipeline through two sliding flanges; and the other end of one vacuum magnetic suspension pipeline and the other end of the other vacuum magnetic suspension pipeline are respectively communicated with the adjacent vacuum magnetic suspension pipeline through two fixing flanges. The vacuum magnetic levitation pipeline structure provided by the embodiment of the invention not only can disperse temperature stress, but also can avoid transmission and accumulation of the temperature stress, so that the vacuum magnetic levitation pipeline structure can be prevented from being damaged.

Description

technical field [0001] The invention belongs to the technical field of vacuum high-speed maglev transportation, and more particularly relates to a vacuum maglev pipeline structure. Background technique [0002] Vacuum high-speed maglev transportation technology is a technology that combines vacuum pipeline and maglev technology. Due to breaking through the constraints of air resistance, noise and wheel-rail adhesion, the speed can reach 600-1000km / h, filling the gap between high-speed rail and air transportation. Speed ​​blank area. With the breakthrough of high-power traction drive technology, it can reach 1000km / h and above, or even higher speeds of supersonic or supersonic speed, becoming a long-distance urban or ultra-long-distance intercontinental transportation mode that supplements or replaces aviation in the future. [0003] However, for a vacuum maglev pipeline of several hundred kilometers, temperature stress will be generated under the influence of aerodynamic he...
