Background
In the prior art, any ground traffic tool including automobiles, high-speed rails, magnetic levitation and the like is limited by air resistance and aerodynamic noise, the commercial running speed of the ground traffic tool is not more than 400km/h, and if the ground traffic tool is required to reach higher running speed, the ground traffic tool is preferably placed in a vacuum or low-vacuum pipeline. The vacuum pipeline transportation system is a vehicle system which runs in a low-atmospheric-pressure (10-20KPa) or high-vacuum-degree sealed pipeline, and mainly comprises vehicles, pipelines, tracks, stations, turnouts, vacuum monitoring, escape systems and the like.
At present, most of the existing turnouts of magnetic suspension are medium-low speed magnetic suspension turnouts, the structure is a three-section centering type, and the turnouts are equipment integrating structure, machinery and control. The turnout mainly comprises a pile beam, a section of driving beam (a double-span continuous steel beam with a vertical support in the span), a first section of driven beam (a simply supported steel beam) and a second section of driven beam (a simply supported steel beam), and an F rail arranged on the upper flange of the beam. The main beam and the two driven beams both have a rotation center fixed on the ground, so the three-section centering type is obtained. Because the turnout is in a zigzag shape when positioned on a lateral line, in order to reduce the relative rotation angle between adjacent beam sections so as to improve the passing performance of the train, an angle bisecting device for reducing the folding angle between the beam sections is arranged between the beam sections. In order to ensure the connection precision between the turnout in place and the turnout back line, an adjustable transition device is arranged at the movable end of the turnout. The track switch is realized by moving one end of the turnout left and right.
Due to the particularity of the vacuum pipeline transportation system, the vehicle conversion track of the vacuum pipeline transportation system is different from the traditional high-speed rail and magnetic suspension track, and due to the fact that the vacuum pipeline vehicle is high in running speed and limited in space, a plurality of defects can be caused when movable turnouts are laid like a railway; at least the following disadvantages are included:
firstly, the turnout structure is complex, and a turnout machine, a centering mechanism, a control system and the like are required;
secondly, the turnout response time is long, and the turnout conversion needs about ten seconds, so that the rapid operation of other vehicles on the main line is influenced;
thirdly, the manufacturing cost is high, and a plurality of professional devices are needed;
fourthly, because the vacuum pipeline is high in speed and large in turning radius, a long turnout is needed;
fifthly, the turnout pipeline is wide and long in laying, too long in cost of land waste and materials, difficult to control and difficult to guarantee the precision;
sixthly, the switch is not timely, and the vehicle has the derailment risk.
