Background
The magnetic suspension train realizes the track direction change through the switch in the operation process. At present, common turnouts for magnetic-levitation train tracks are deformed and arranged in a transverse structure, and the turnout beam has the characteristics of large transverse width, large forced elastic deformation, long rail-changing time, high deformation control precision requirement and the like. In addition, the occupied area of the turnout of the transverse structure is very large, and the construction cost is high.
Therefore, how to minimize the elastic deformation of the points is an important technical problem that those skilled in the art need to solve at present. In addition, reducing the occupied area and the construction cost of magnetic levitation is also a key concern for magnetic levitation operation and building units.
Disclosure of Invention
In order to solve the technical problems, the invention provides a turnout structure for a magnetic-levitation train track, which comprises a high-area track passing beam, a low-area track passing beam and a longitudinal lifting deformation beam, wherein the longitudinal lifting deformation beam comprises a plurality of piers with lifting capacity and a lifting deformation beam body with elastic deformation capacity;
when the piers with lifting capacity in the longitudinal lifting deformation beam are lifted in place, the lifting deformation beam body is connected with the high-area track through the beam body, and a train enters the high-area track through the lifting deformation beam body or enters the lifting deformation beam body from the high-area track through the beam body;
after piers with lifting capacity in the longitudinal lifting deformation beam land in place, the lifting deformation beam body is connected with the low-zone track through the beam body, and a train enters the low-zone track through the lifting deformation beam body or enters the lifting deformation beam body from the low-zone track through the beam body.
Compared with the background technology, the turnout for the track of the magnetic-levitation train provided by the invention has the following beneficial effects: the turnout adopts longitudinal deformation to replace the original transverse deformation, so that the deformation width of a beam body is reduced; only piers with lifting capacity are adopted to replace original complex driving structures such as gear racks and the like, so that the structure of a turnout driving mechanism is simplified; particularly, the invention realizes the deformation of the rail by a longitudinal rail lifting mode, compared with the prior transverse bending mode, the deformation of the rail is realized, and the occupied area of the turnout building is greatly reduced. If the high-area track is used for a station platform through the beam, kinetic energy can be converted into potential energy before the train enters the station, energy recovery is realized, and the train braking distance is reduced; and the symmetrical turnout structure adopted after the train is dispatched from the station can realize the conversion of potential energy into kinetic energy, reduce the train acceleration time and realize the green energy-saving effect.
