Description

Technical Field

[0001] The invention relates to the technical field of magnetic levitation rail transportation, and more specifically to a turnout supporting and guiding device of an embedded magnetic levitation transportation system. Background Art

[0002] Due to its own characteristics, the medium and low-speed maglev transportation system will play an important role in the future development of urban rail transit. In particular, it may become an important choice for some cities where it is difficult to build subways due to geological conditions. It will inevitably become a widely used rail public transportation tool for urban, inter-city, short-distance intercity, and tourist scenic area transportation connections, and has extremely broad market prospects.

[0003] The embedded maglev transportation system has the advantages of high structural rigidity, high transportation capacity, fast running speed, low comprehensive energy efficiency, strong climbing ability, small turning radius, fast acceleration, low magnetic radiation and noise, etc. It can be widely used in more than 90% of the urban rail transit market, such as subway, light rail, urban express rail, short-distance intercity and tourist transportation, and can completely replace the traditional urban rail transit system and realize a revolution in the development of urban rail transit.

[0004] The turnouts of the embedded maglev transportation system are also different from those of other standard wheel-rail transportation systems. They use multiple short straight line units to fit into turnout curves with various curvature radii. They are composed of turnout units, movable joints, turnout guides, turnout plates, drive devices, tensioning devices, locking devices, etc.

[0005] During the operation of the switch of the embedded maglev transportation system, the switch unit must swing horizontally, slide vertically, and rotate around itself. This requires that the support and guide device of the switch unit has sufficient rigidity to enable the vehicle to run along the predetermined track; has a certain degree of elasticity to reduce the bounce and impact of the vehicle when passing the switch; and can also adapt to the flexural deformation of the switch unit.

[0006] Due to the limitation of manufacturing and installation precision, according to the traditional design, a gap is set between the supporting guide device and the guide rail. This gap can eliminate manufacturing and installation errors, but it also causes a certain difference between the movement trajectory of the turnout unit and the design. Under the impact force when the vehicle passes the turnout, the turnout unit will shake and deviate due to the gap of the guide device, which poses a certain safety hazard to the operation of the vehicle.

DETAILED DESCRIPTION

[0033] All features disclosed in this specification, or steps in all methods or processes disclosed, except mutually exclusive features and / or steps, can be combined in any manner.

[0034] Any feature disclosed in this specification, unless otherwise stated, can be replaced by other equivalent or alternative features with similar purposes. That is, unless otherwise stated, each feature is only an example of a series of equivalent or similar features.

[0035] The invention provides a novel built-in turnout support and guide device for a maglev transportation system.

[0036] Figure 1 A schematic diagram of the arrangement structure of a turnout support and guide device of an embedded maglev transportation system on a turnout according to an exemplary embodiment of the present invention is shown.

[0037] like Figure 1 As shown, the turnout support guide device of the embedded maglev transportation system in the present invention is applicable to a segmented structure and includes a plurality of turnout units 1 which are sequentially connected and located above the turnout foundation, and each turnout unit 1 is provided with at least one set of turnout support guide devices. The at least one set of turnout support guide devices provided in each turnout unit 1 cooperates with at least one turnout guide rail 2, which is fixed on the turnout foundation and has an I-shaped structure.

[0038] According to a preferred embodiment of the present invention, the turnout is composed of a plurality of linear turnout units 1, each of which is provided with two sets of turnout support guide devices and two turnout guide rails 2 are correspondingly provided on the turnout base, and the turnout unit 1 slides on the turnout guide rails 2 with the help of the turnout support guide devices to achieve horizontal movement and rotation. When the vehicle needs to run along the main line, each turnout unit 1 moves to a straight line position and fits into a straight line; when the vehicle needs to run along the side line, each turnout unit 1 moves to a side line position and fits into a curve.

[0039] Among them, the turnout guide rail 2 is arranged on the turnout foundation, and its two side surfaces are guide surfaces, which bear the horizontal force required for the operation of the turnout unit 1; its top surface is the supporting surface, which bears the vertical force required for the operation of the turnout unit 1; the lower surface of the upper flange of the turnout guide rail is a tensile surface, which can weaken the vibration of the turnout unit 1 caused by the vehicle.

[0040] The turnout support and guide device of the embedded maglev transportation system of the present invention is described in detail below.

[0041] Figure 2 A schematic diagram of the installation structure of a turnout support guide device for an embedded maglev transportation system at the bottom of a turnout unit according to an exemplary embodiment of the present invention is shown. Figure 3 A schematic diagram of the installation cross-sectional structure of a turnout support and guide device of an embedded maglev transportation system according to an exemplary embodiment of the present invention is shown.

[0042] like Figure 2 and Figure 3 As shown, according to an exemplary embodiment of the present invention, the turnout support guide device is arranged between the turnout unit 1 and the turnout guide rail 2, and the turnout unit 1 can slide along the turnout guide rail 2 with the help of the turnout support guide device. Specifically, the turnout support guide device includes components such as a support mechanism 3, a fixed guide mechanism 4, a movable guide mechanism 5 and a tension mechanism 6, and basically completely wraps the turnout guide rail 2, and is connected to the side of the turnout unit 1 through connecting members such as bolts.

[0043] Figure 4 A structural schematic diagram of a support mechanism in a turnout support guide device of an embedded maglev transportation system according to an exemplary embodiment of the present invention is shown.

[0044] like Figure 4 As shown, the support mechanism 3 of the present invention includes a seat body 11, a running wheel 18 and a connecting portion. The seat body 11 has a accommodating cavity for accommodating the running wheel 18. The running wheel 18 is arranged in the accommodating cavity of the seat body 11 and can run on the top surface of the turnout guide rail 2. The top of the seat body 11 is connected to the turnout unit 1 through the connecting portion.

[0045] The axle of the running wheel 18 is arranged in the accommodating cavity of the seat body 11 and connected to the seat body 11, that is, the seat body 11 can be entirely arranged on the axle of the running wheel 18, and the running wheel 18 is preferably arranged at least two. When the turnout switches, the turnout unit 1 can move to the designated position smoothly and lightly with the help of the running wheel 18.

[0046] The connecting part of the supporting mechanism 3 includes a connecting flange 12, a first rubber plate 13, a spherical fitting assembly, a second rubber plate 17, a mirror plate 16 and a first fixing member. The connecting flange 12 passes through the top of the base body 11 and is fixed to the base body 11 through the first fixing member. The spherical fitting assembly is arranged between the connecting flange 12 and the upper surface of the top of the base body 11, the first rubber plate 13 is arranged between the spherical fitting assembly and the connecting flange 12, the mirror plate 16 is arranged between the lower surface of the top of the base body 11 and the first fixing member, and the second rubber plate 17 is arranged between the base body 11 and the mirror plate 16.

[0047] Since the turnout support guide device adopts the support mechanism 3 of the above structure, when a vehicle passes, the first rubber plate 13 and the second rubber plate 17 can weaken the vibration caused by the vehicle. The mirror plate 16 arranged between the seat body 11 and the second rubber plate 17 can reduce the deflection resistance caused by the connecting flange 12 when the turnout unit 1 is deformed, thereby protecting the support guide device from being damaged.

[0048] The spherical mating assembly of the present invention includes a spherical pad 14 and a spherical concave pad 15 that cooperate with each other. The spherical concave pad 15 is embedded in a corresponding groove set on the top upper surface of the seat body 11. The cooperation between the spherical pad 14 and the spherical concave pad 15 can adapt to the deflection deformation of the turnout unit 1 and the deflection of the connecting flange 12 caused by the deflection deformation of the turnout unit 1. In addition, the spherical pad 14 and the spherical concave pad 15 are preferably made of wear-resistant materials with lubricating function, and the friction resistance when rotating relative to each other is small and the subsequent maintenance work can be reduced.

[0049] like Figure 3 and Figure 4As shown, the fixed guide mechanism according to the present invention includes a fixed guide wheel 8 and a fixing portion, the fixed guide wheel 8 is fixed to one side of the seat body 11 through the fixing portion, and the fixed guide wheel 8 can be closely attached to the guide surface on one side of the turnout guide rail 2 and roll along the guide surface on one side of the turnout guide rail 2. Preferably, the fixing portion of the fixed guide mechanism 4 includes a pressure plate 7 and a second fixing member, the pressure plate 7 is fixed to one side of the seat body 11 through the second fixing member and fixes the fixed guide wheel 8. Among them, the seat body 11 is generally a "π"-shaped structure with a accommodating cavity and is a left-right asymmetric structure. When viewed in the lateral direction, it can be arranged above the turnout guide rail 2. The above-mentioned one side of the seat body 11 refers to one side of the left and right sides in the lateral direction, and the fixed guide wheel 8 is fixed to the side of the seat body 11 through the pressure plate 7 and a second fixing member such as a bolt.

[0050] Figure 5 A schematic structural diagram of a movable guide mechanism in a turnout support guide device of an embedded maglev transportation system according to an exemplary embodiment of the present invention is shown.

[0051] like Figure 5 As shown, the movable guide mechanism of the present invention includes a clamping part, a movable guide assembly and an elastic adjustment assembly. The clamping part is fixed on the other side of the seat body 11. The movable guide assembly and the elastic adjustment assembly are both mounted on the clamping part. The movable guide wheel 20 in the movable guide assembly can be tightly attached to the guide surface on the other side of the turnout guide rail 2 under the tension of the elastic member 22 in the elastic adjustment assembly and roll along the guide surface on the other side of the turnout guide rail 2. The other side of the seat body 11 is the other side opposite to the side of the seat body where the fixed guide wheel 8 is installed. Therefore, the movable guide mechanism can work together with the fixed guide mechanism so that the turnout unit can only run along the turnout guide rail.

[0052] Specifically, the clamping part of the movable guide mechanism 5 can be a clamping shaft 19, and the clamping shaft 19 can be connected to the support mechanism 3 by bolts and other connecting parts. The movable guide assembly includes a guide wheel mounting frame 21 and two movable guide wheels 20. The guide wheel mounting frame 21 is mounted on the clamping shaft 19 and the two movable guide wheels 20 are arranged on both sides of the guide wheel mounting frame 21. The elastic adjustment assembly of the movable guide mechanism 5 includes an elastic member 22 and an adjustment nut 23. The elastic member 22 can be a clamping spring. The elastic member 22 is mounted on the outer side of the guide wheel mounting frame 21 on the clamping shaft 19 in a pre-tensioned state. The adjustment nut 23 is arranged at the end of the clamping shaft 19 and can adjust the tension of the elastic member 22. At the same time, the movable guide mechanism can compensate for the lateral displacement of the turnout unit 1 relative to the turnout guide rail 2.

[0053] Further preferably, a slide groove is provided in the guide wheel mounting frame 21, and the section on the clamping shaft 19 that matches the slide groove of the guide wheel mounting frame 21 is a square shaft section, so that the guide wheel mounting frame 21 can only slide axially along the clamping shaft 19. Under the action of the elastic member 22, the guide wheel mounting frame 21 moves toward the turnout guide rail 2, so that the movable guide wheel 20 is always close to the side of the turnout guide rail 2.

[0054] According to the needs of actual application, the tension of the elastic member 22 can be adjusted by rotating the adjusting nut 23 to ensure the close contact of the movable guide wheel 20 and weaken the lateral force of the turnout unit 1 caused by the vehicle. The fixed guide mechanism and the movable guide mechanism 5 work together to make the turnout unit 1 only run along the turnout rail 2.

[0055] The anti-tension mechanism 6 of the present invention includes anti-tension units symmetrically arranged on both sides of the turnout rail 2, and the anti-tension unit includes a support portion and an anti-tension guide wheel 9. One end of the support portion is fixed on the seat body 11 and the other end extends below the upper flange of the turnout rail 2. The support portion can also be integrally formed with the seat body 11. The anti-tension guide wheel 9 is fixed on the support portion and can roll along the bottom surface of the upper flange of the turnout rail 2. Among them, the anti-tension guide wheel 9 of the anti-tension mechanism includes a plurality of rollers laid side by side along the turnout rail 2, so that it can roll along the turnout rail 2.

[0056] In order to cooperate with the anti-tension guide wheel 9, a pre-compressed rubber plate 10 is provided on the other end of the support portion of the anti-tension mechanism 6 extending below the upper flange of the turnout guide rail 2. The pre-compressed rubber plate 10 is a rubber plate installed in a pre-compressed state and can directly contact the anti-tension guide wheel 9. When the turnout unit jumps due to the passage of a vehicle, the pre-compressed rubber plate 10 can weaken the jump, and the pre-compressed rubber plate 10 has a large pressure, and the friction resistance of the anti-tension guide wheel 9 on it is also small.

[0057] That is, the tension mechanism 6 can offset the bouncing of the switch unit 1, and the pre-compressed rubber sheet 10 can reduce the impact caused by the bouncing and improve the running comfort of the vehicle.

[0058] To sum up, the turnout support and guide device of the embedded maglev transportation system of the present invention can always tightly wrap the turnout guide rail, thereby improving the position accuracy of the turnout unit; the structural optimization can attenuate the impact force when the vehicle passes the turnout and weaken the turnout unit jumping caused by the vehicle, while reducing the swing resistance of the turnout unit and adapting to the deflection deformation of the turnout unit, thereby effectively improving the comfort of vehicle operation.

[0059] The above description is only a specific embodiment of the present invention, and the present invention is not limited to the above specific embodiments. Any changes or substitutions that can be easily thought of by a person skilled in the art within the technical scope disclosed in this application should be included in the protection scope of this application, and the protection scope of this application should be based on the protection scope of the claims.
