Description

Maglev system line turnout structure

technical field

The utility model relates to the field of rail transportation, in particular to the field of maglev system lines, in particular to a maglev system line turnout structure.

Background technique

The biggest difference between the maglev high-speed transportation system and the traditional railway transportation system is that it is a non-contact rail transportation system without wheels, relying on track equipment and the support and guidance system of the maglev train to realize the support, guidance and driving of the train.

This non-contact mode between the vehicle and the track makes it impossible for the maglev system to use the turnout equipment commonly used in the railway transportation system when the line diverges. In the prior art, the method of forced elastic deformation of the entire turnout steel beam is used to change the line. Germany has researched and developed various types of maglev line turnouts since the 1970s. At present, the types of turnouts used on the Shanghai demonstration line built with maglev technology imported from Germany are double-opening and three-opening. The straight-line passing speed It is not affected by the setting of the turnout, and the power rail must be set within the range of the turnout.

Because the turnout in the prior art adopts the method of forced elastic deformation of the entire turnout steel beam to realize line change, the steel beam of the turnout has the problem of low lateral stiffness, which leads to a large vibration amplitude of the turnout steel beam when the train passes, affecting passenger comfort.

At the same time, the planar alignment requirements of this kind of turnout are: straight line-clothoid curve-circular curve-clothoid curve-straight line. However, according to the current line changing method of elastic side bending, each section of the curve can only be a cubic curve.

Utility model content

The purpose of this utility model is to overcome the above-mentioned shortcomings in the prior art, and provide a kind of elastic lateral bending section with small range, large lateral rigidity of turnout steel girder, small vibration amplitude of steel girder, safe and quick track change, and flexible and simple implementation. The turnout structure of the magnetic levitation system.

In order to achieve the above-mentioned purpose, the switch structure of the maglev system of the present invention has the following structure:

This kind of turnout structure of the maglev system includes a front moving section, a rear moving section and a track section behind the turnout. The functional part is provided with a running and positioning mechanism under the functional part. The rear moving section of the switch includes a fixed switch center and a rear switch conversion function mechanism, and a switch conversion control mechanism is provided under the functional part.

The rear turnout transformation function mechanism of the turnout rear moving section of the line turnout structure of the maglev system is two functional parts supported on the fixed turnout center and rotating around the axis of the vertical plane of the fixed turnout center. The turnouts under the function parts The conversion control mechanism is a rotary drive mechanism.

The rear turnout transformation function mechanism of the turnout rear moving section of the turnout structure of the maglev system is a double-sided functional part that is supported on the fixed turnout center and rotates around the axis of the vertical plane of the fixed turnout center and can be elastically bent sideways. The switch conversion control mechanism under the functional part includes a rotation drive mechanism and a travel and positioning mechanism.

The running and positioning mechanism under the elastically side-bending functional part of the maglev system circuit turnout structure includes a side-shift positioning system installed on the functional part, a side-shift driving system and a side-shift guiding device perpendicular to the functional part.

Due to the adoption of the turnout structure of the maglev system of the utility model, the turnout center is fixed, and it is not necessary to realize the bending through the elastic deformation of the whole beam, and the elastic deformation bending part is only limited to the moving functional parts at the front of the turnout, so that the turnout steel The lateral stiffness of the beam is greatly improved, thereby reducing the vibration amplitude when the train passes the turnout; at the same time, the operation of changing the line is safe and fast, with high reliability and efficiency, and it is more flexible and convenient in the design and construction.
