Side wall lifting translation type high-speed magnetic levitation turnout structure and control system thereof

Abstract

The invention discloses a side wall lifting translation type high-speed magnetic levitation turnout structure. A magnetic levitation turnout beam comprises a translation section, a lifting section and a rotating section which are arranged in sequence; the translation section at least comprises a first translation beam and a second translation beam; the lifting section comprises a turnout main beam and fixed side walls arranged on the two sides of the main beam, a first lifting side wall and a second lifting side wall are arranged in the middle of the main beam, and the two lifting side walls alternately ascend and descend to form a straight strand U-shaped beam and a side strand U-shaped beam when the maglev train runs; the rotating section comprises a main beam, fixed side walls arranged on the two sides of the main beam and a rotating type side wall arranged in the middle of the main beam, and the rotating type side wall can rotate to be in butt joint with the first lifting side wall or the second lifting side wall. The invention further discloses a high-speed magnetic levitation turnout control system. By the adoption of the split type design, the manufacturing difficulty of the beam body is effectively reduced, the structure is compact, operation and maintenance are convenient, the partition turnout modules and the turnout machine are integrally designed, and the field construction and debugging efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of maglev turnouts, and in particular relates to a U-shaped side wall lifting translation type high-speed maglev turnout structure and a control system thereof. Background technique [0002] The maglev transportation system is currently the fastest and most technologically advanced transportation system among ground transportation systems in the world. It mainly relies on electromagnetic force to realize the functions of support, guidance, traction and braking. Compared with conventional wheel-rail trains, it has the characteristics of low noise, low energy consumption, no pollution, safety and comfort, and high speed and high efficiency. It is considered to be a new type of transportation with broad prospects. [0003] The turnout is an important part of the track structure system in the maglev train system. Compared with railway turnouts, maglev turnouts are quite different. Maglev turnouts are actually ...

AI Technical Summary

Problems solved by technology

[0004] At present, the commonly used maglev turnout drives the magnetic track to translate through the translational drive, so that the two permanent magnet rails are docked to complete the turnout. This driving track is used to turn the turnout. The track system occupies a large area, and the cost of infrastructure construction and maintenance is high. Turnout The operating efficiency is low and the economy is poor

In addition, the existing maglev turnout control system equipment is redundant, single-function, and low in integration. For the Decentralized Switch Module (DSM) and the maglev turnout machine (SwitchController, SC), DSM and SC are provided by different manufacturers to provide communication interfaces between devices. , there is no uniform standard in the agreement, which is not conducive to the engineering installation of maglev trains, and affects the efficiency of on-site construction and commissioning

In addition, the commonly used driving method of maglev turnout adopts distributed loading, and the coordinated operation of multiple driving points is not achieved. There is local stress concentration during the turnout process, which affects the life of maglev turnout and even endangers the operation safety of the train.
