[0025] Combine Figures 1 to 5 As shown, the embodiment provides an embedded medium- and low-speed maglev slideway switch system comprising: a switch guide system 10 and a switch body.

[0026] like Figure 1 As shown, the switch guide system 10 includes a base 11, with multiple slide rails 12 spaced apart and embedded within the base 11. The slide rails 12 extend in a curve, conforming to the curved characteristics of the switch. A slider 13 is slidably disposed within each slide rail 12. The sliders 13 in adjacent slide rails 12 are hingedly connected by connecting rods 14. The first slider 13 at the front serves as the active slider 131, while the remaining sliders 13 serve as passive sliders 132. The active slider 131 is connected to a drive device 15.

[0027] In this embodiment, the drive device 15 includes a hydraulic rod 151 and a drive motor 152. The hydraulic rod 151 is connected to the active slider 131, and the drive motor 152 is used to provide a switching guide force. The hydraulic rod 151 is located within the slide rail 12 where the active slider 131 is located, and the drive motor 152 is located at the end of the slide rail 12. When the active slider 131 moves under the drive of the drive motor 152, it pulls each of the driven sliders 132 to follow it.

[0028] Each of the slide rails 12 is designed with a corresponding curve and length according to the design requirements, thereby defining the curve linearity of the turnout. Figure 5 As shown, the connecting rod 14 is hinged to the center of the slider 13 (the label a in the figure represents the slider axis of the slider 13, and the connecting rod 14 can rotate around the slider axis), and there is an angle restriction between the connecting rod 14 and the slider 13, that is, the connecting rod 14 can only rotate at a fixed angle with the slider 13.

[0029] In this embodiment, the slider 13 at the front end is used as the active slider 131, and the other driven sliders 132 follow the active slider 131 to switch through limiting. In this way, the entire turnout only needs to be equipped with one drive device to provide power. If other sliders are used as active sliders, the limiting conditions will be different when there are sliders in front and behind them, and multiple drives will need to be set up for coordinated control.

[0030] like Figure 2a 、 Figure 2b As shown, the turnout body includes a plurality of turnout units 20, and one turnout unit 20 is fixed on each slider 13. Specifically, the turnout unit 20 includes a beam body 21, and the beam body 21 is made of steel to have a good load-bearing capacity. Load-bearing wheels 22 are provided under the four corners of the beam body 21, and the load-bearing wheels 22 are in contact with the base 11, thereby playing a role in assisting the turnout switching and bearing the load. The beam body 21 has an upward opening, and grooves 211 are formed on both sides of the opening. A power supply rail 23 is provided in the groove 211 for supplying power to the maglev train. Wedge blocks 24 are provided on both sides of the opening, and an F rail 25 is provided on the wedge blocks 24. The F rail 25 is used for suspension and traction of the train.

[0031] like Figure 3 、 Figure 4 As shown, the switching principle of the embedded medium and low speed maglev slideway switch system provided in this embodiment is as follows: the switch units 20 are connected by the slider 13 and the connecting rod 14, and there is a gap between the switch units 20. When the switch is switched, the driving motor 142 drives the hydraulic rod 141 to give the active slider 131 a guiding force to switch to the siding. The active slider 131 drags the driven slider 132 through the connecting rod 14 to move synchronously to the siding at a specified angle. After the switch units 20 connected by each slider 13 move according to the moving curve of the slider 13 to reach a predetermined position, the slider 13 is locked with the slide rail 12 to lock the switch in the siding position.

[0032] When the turnout switches from the side line position to the main line position, the allowable angle between the slider 13 and the connecting rod 14 is as follows: Figure 5 As shown, α is the maximum rotation angle allowed for the connecting rod 14 and the slider 13. When turning from the siding to the main line, the angle limitation allows the switch to successfully become the main line position. Therefore, when the drive motor 142 drives the active slider 131 toward the main line, the connecting rod 14 will adjust the sliders 13 to a straight line, thereby pulling and pushing them to the main line position, and locking them after reaching the position. It should be noted that the design of the angle α involves the specific design length of the switch and the number of switch units 20, and the angle limitation is mainly to allow the driven slider 132 to follow the active slider 131 back to the fixed position when the switch returns from the siding position to the main line position.

[0033] The method of locking the slider 13 and the slide rail 12 is a conventional technique. For example, a locking pin may be provided at a specified position, and the slider 13 may be locked by the locking pin after reaching the specified position.

[0034] In summary, the present invention optimizes the turnout structure and installs various turnout equipment in an embedded turnout, which is convenient for inspection and maintenance; uses load-bearing wheels and slide rails to achieve turnout turning and guiding, reducing turnout wear and failure problems.

Furthermore, a first feature being "above," "above," and "above" a second feature may include the first feature being directly above or obliquely above the second feature, or may simply mean that the first feature is higher in level than the second feature. A first feature being "below," "below," and "below" a second feature may include the first feature being directly below or obliquely below the second feature, or may simply mean that the first feature is lower in level than the second feature.
