The turnout beam, as a key component, is supported by a fixed crossbeam and five movable trolleys. These trolleys are arranged on supports, forming the main structure of the turnout system. Each trolley requires an independently operating switching device and locking pin device, resulting in a complex mechanical structure and a series of technical problems inherent in the existing turnout system. In particular, the switching action of high-speed maglev turnouts involves three independent steps: unlocking, rotating, and locking. The entire process is time-consuming, affecting the operating efficiency of maglev trains. Therefore, there is an urgent need to develop a new type of high-speed maglev turnout.

[0028] Compared with the prior art, the present invention has at least the following technical effects: This invention provides a novel conventional high-speed maglev turnout, mainly comprising a turnout beam, a fixed support point and multiple running devices, several drive transmission components, several locking devices, and a foundation platform. This invention can effectively improve system stability and rigidity, reduce mechanical wear, increase operating efficiency, and facilitate inspection and maintenance.

[0029] Specifically, the locking device of the present invention adopts a mechanical locking method. The locking-turning-unlocking action is realized by the linkage between the drive transmission component and the locking device. Compared with the prior art, there is no need to set up a power device for the locking device, which saves costs, reduces the difficulty of system control, greatly saves the time required for the turnout turning action ("unlocking-turning-locking"), and improves the operating efficiency of the entire railway system, that is, improves the operating efficiency of maglev trains.

[0030] The locking device of the present invention is arranged on both sides of the turnout centerline. This design significantly enhances the stiffness of the turnout beam in the Y direction, making the turnout more stable when subjected to Y-direction loads, that is, improving the stiffness of the Y-direction system.

[0031] The traveling device of this invention simplifies the design of existing turnout trolleys, with a simple structure that only performs the traveling function. The traveling device no longer requires drive transmission components and locking devices. This change reduces wear and jamming problems caused by complex shaft transmission systems, thus reducing mechanical wear and extending the service life of the traveling device.

[0032] The drive transmission components and locking devices are no longer installed on the running gear; this allows the total height of the turnout (the height perpendicular to the XY plane) of the present invention to be reduced, and stability to be increased.

[0033] In addition, the traveling device of the present invention includes an auxiliary traveling device to further improve vertical (perpendicular to the XY plane) stiffness.

[0034] This invention provides a basic platform that includes the entire working range of the turnout. Compared to existing technologies where the turnout is set on separate supports with only an operating platform on the supports, which makes it inconvenient to maintain and repair the entire turnout, the entire basic platform of this invention can be used as an operating platform, thereby facilitating the maintenance and repair of the entire turnout and the evacuation of personnel in special circumstances.

[0035] The drive transmission assembly of the present invention adopts a push rod transmission assembly or a crank-rocker assembly. The guide groove that interacts with the push rod and rocker is directly installed on the turnout beam. This can avoid wear and jamming similar to the complex shaft transmission of existing trolleys, and also effectively reduce the height of the running device and increase stability.

Detailed Implementation

[0037] The following detailed description, in conjunction with the accompanying drawings and specific embodiments, provides a further detailed explanation of the conventional high-speed maglev traffic turnout proposed in this invention. The advantages and features of this invention will become clearer from the following description. It should be noted that the drawings are in a very simplified form and use non-precise proportions, intended only to facilitate and clearly illustrate the embodiments of this invention. Please refer to the drawings to make the objectives, features, and advantages of this invention more apparent and understandable. It should be understood that the structures, proportions, sizes, etc., depicted in the accompanying drawings are only for illustrative purposes and to enable those skilled in the art to understand and read them, and are not intended to limit the implementation conditions of this invention. Therefore, they have no substantial technical significance. Any modifications to the structure, changes in proportions, or adjustments to the size, without affecting the effects and objectives achieved by this invention, should still fall within the scope of the technical content disclosed in this invention.

[0038] As described in the background section, existing maglev trains require separately installed, independently operating switching devices and locking pin devices, resulting in complex mechanical structures and reduced operating efficiency. Specifically, for example... Figure 1 As shown, Figure 1 Figure b is a top view of the existing conventional high-speed maglev turnout with the turnout beam removed. Figure 1 Figure a shows a schematic diagram of the side structure of an existing conventional high-speed maglev turnout in the X direction. Combined with... Figure 1 As shown in Figures a and b, the domestic conventional high-speed maglev turnout is an integral elastic side-bending turnout. The turnout beam 0 is a continuous steel beam, supported by a fixed crossbeam 1 and five movable trolleys 2. The fixed crossbeam 1 and the five trolleys 2 are respectively arranged on six independently set piers Z0~Z5. The turnout beam 0 is connected to the trolleys 2 by a group of bolts.

[0039] All the trolleys 2 of the supports Z1 to Z5 are equipped with locking pin devices 3 and traveling devices 4. The trolleys 2 of supports Z3 and Z5 are also equipped with drive motors 6 and transmission gears 7.

[0040] like Figure 2 As shown, after the locking pin device 3 and the traveling device 4 are installed on the trolley 2, the turnout beam 0 and the trolley 2 are large in size, and the overall height h of the turnout reaches 2.645m, which reduces the stability of the existing turnout.

[0041] Please continue to refer to this. Figure 2 As shown, it gives Figure 1 The diagram shows the AA section structure at the Z1 position in Figure a. Locking pin devices 3, traveling devices 4, and drive shafts 5 are installed on the trolleys 2 of Z1, Z2, and Z4. The traveling device 4 includes traveling wheels mounted on the drive shaft 5. The drive shaft 5 extends in the X direction, and the traveling wheels generally move in the Y direction.

[0042] like Figure 3 As shown, Figure 1 The schematic diagram of the BB section structure at the Z5 position in Figure b shows that, in addition to the traveling wheels of the traveling device 4, the locking pin device 3, and the drive shaft 5, the trolley 2 of both Z3 and Z5 is also equipped with a drive motor 6 and a transmission gear 7. The drive motor 6 is used to drive the drive shaft 5 to rotate. The traveling wheels and the transmission gear 7 share the same drive shaft 5, resulting in complex stress on the shaft (system) and high maintenance difficulty.

[0043] like Figure 4 As shown, and Figure 1 As shown in Figure a, at positions Z1 to Z5, locking pin devices 3 and locking pin motors 9 are installed at the centerline of all trolleys 2 at positions Z1 to Z5, with corresponding locking devices 8 installed on the ground. When the locking pin motor 9 rotates, the locking pin device 3 retracts, moving away from the locking device 8, thus unlocking; when the locking pin motor 9 rotates in the opposite direction, the locking pin device 3 moves forward, inserting into the locking device 8, thus locking in the Y direction.

[0044] When the turnout is switched, firstly, the locking pin motor 9 of the locking pin device 3 on the supports Z1~Z5 works, the locking pin rod 3-1 is pulled out, and the turnout is unlocked; then, the drive motor 6 on the supports Z3 and Z5 works, the transmission shaft 5, the transmission gear 7 and the traveling wheel push the trolley 2 and drive the turnout beam 0-0 to turn until the designed target position is reached; finally, the locking pin motor 9 works in reverse, the locking pin rod 3-1 of the locking pin device 3 extends to the locking device 8, and the turnout is locked.

[0045] The existing turnout has the following problems: (1) The turnout switching action is to unlock the locking device 3 by driving the locking pin device 3 through a separate locking pin motor 9, drive the transmission shaft 5 and the traveling wheel 4 through the drive motor 6 to make the turnout rotate, and then lock the locking device 3 through the locking pin motor 9. The entire turnout switching time is relatively long. (2) The trolley is equipped with traveling, locking pin and drive devices, with a total height of 2.65m, and the system stability is poor. (3) The trolley integrates traveling, drive transmission and locking functions, so the mechanical transmission and traveling components are prone to jamming and wear during the turnout switching process. (4) The lateral (Y direction) locking target is achieved by the locking pin device 3 installed in the center of the line, and the structural rigidity is relatively low. (5) There is only an operating platform at the support position, which is not conducive to the daily maintenance and repair of the entire turnout, nor is it conducive to setting up evacuation channels.

[0046] like Figure 5 As shown, where Figure 5 Figure a shows a top view of the turnout when it is in the siding position. Figure 5Figure b shows a top view of the turnout in a straight position; this embodiment provides a normal-conducting high-speed maglev traffic turnout, including: a turnout beam 20, which is formed by connecting multiple steel beam segments to form an integral continuous steel beam, wherein the turnout beam 20 in a straight position (e.g. Figure 5 As shown in Figure b, when the turnout beam 20 is straight, its length direction is X-axis, its width direction is Y-axis, and its height direction is Z-axis, thus forming a three-dimensional coordinate system.

[0047] A fixed support point 30 is used to fix and support one end of the turnout beam 20 so that the turnout beam 20 can achieve Y-direction turning around the fixed support point 30 in the XY plane.

[0048] Multiple traveling devices (see reference) Figure 5 As shown in reference numerals 31 and 32), they are arranged at intervals along the X direction below the turnout beam 20 to support the turnout beam 20.

[0049] At least one drive transmission assembly 40 is arranged at intervals along the X direction below the turnout beam 20 to provide turning driving force to the turnout beam 20. In this embodiment, there may be multiple drive transmission assemblies 40.

[0050] At least one locking device 50 is arranged at intervals along the X-direction below the turnout beam 20. The locking device 50 is linked with the drive transmission assembly 40 and is used to unlock and lock the turnout beam 20 under the drive of the drive transmission assembly 40. In this embodiment, the number of locking devices 50 is the same as the number of drive transmission assemblies 40, and they can be combined with the drive transmission assembly 40.

[0051] The locking device 50 includes a first locking component 51 and a second locking component 52, which are used to mechanically lock the turnout beam 20 in a straight position and a lateral position, respectively.

[0052] The base platform 10 is used to support the turnout beam 20, the running device, the drive transmission assembly 40, and the locking device 50.

[0053] This embodiment can effectively improve system stability and rigidity, reduce mechanical wear, improve operating efficiency, and facilitate inspection and maintenance.

[0054] Specifically, the locking device in this embodiment adopts a mechanical locking method. The unlocking, switching, and locking actions of the turnout beam are realized through the linkage of the drive transmission component and the locking device. Compared with the prior art, there is no need to set up a power unit for the locking device, which saves costs, reduces the difficulty of system control, greatly saves the time required for the turnout switching action ("unlock-switching-locking"), and improves the operating efficiency of the entire railway system.

[0055] Compared to existing turnout trolley designs, the traveling mechanism in this embodiment is simplified. Its simple structure only performs the traveling function, and the drive transmission assembly and locking device are no longer installed on the traveling mechanism. This change reduces wear and jamming problems caused by complex shaft transmission systems, thus reducing mechanical wear and extending the service life of the traveling mechanism. The removal of the drive transmission assembly and locking device from the traveling mechanism allows for a lower overall height of the turnout in this embodiment, specifically lower than the existing turnout's overall height h=2.645m, increasing the turnout's stability.

[0056] This embodiment has a basic platform that includes the entire working range of the turnout. Compared with the existing technology where the turnout is set on separate supports and the operating platform is only set on the supports, which makes it inconvenient to maintain and repair the entire turnout, the entire basic platform in this embodiment can be used as an operating platform, which facilitates the maintenance and repair of the entire turnout and the evacuation of personnel in special circumstances.

[0057] like Figure 6 As shown, this embodiment also includes a foundation plate 21, which is disposed on the bottom of the turnout beam 20, and the drive transmission assembly 40 and the locking device 50 are disposed on the foundation plate 21.

[0058] It is understandable that the foundation plate 21 is segmented, that is, the foundation plate 21 is only provided at the location of the turnout beam 20 where the drive transmission assembly 40 and the locking device 50 are located.

[0059] Please continue to refer to this. Figure 5 As shown, in this embodiment, the plurality of traveling devices include a plurality of main traveling devices 31 and auxiliary traveling devices 32, which are arranged at intervals along the X-direction below the turnout beam 20. The traveling device provided in this embodiment includes auxiliary traveling devices, which further improves the vertical (perpendicular to the XY plane) stiffness.

[0060] In one embodiment, such as Figure 7 As shown, the specific Figure 7 Figure a shows a Y-direction cross-sectional view of the main traveling device 31; each of the main traveling devices 31 includes: a first crossbeam 311, a traveling wheel 312 and a traveling rail 313; the traveling rail 313 is laid on the base platform 10 and extends along the Y direction.

[0061] In this embodiment, the running track 313 is an arc-shaped track, and the opening of the arc-shaped track faces the fixed support point 30, thereby facilitating the turnout beam 20 to turn around the fixed support point 30 and realize the turnout's lateral bending in the Y direction.

[0062] The first crossbeam 311 is connected to the turnout beam 20. In this embodiment, the first crossbeam 311 is detachably connected to the turnout beam 20 via a bolt assembly.

[0063] The traveling wheel 312 is rotatably connected to the first crossbeam 311 and can roll along the traveling rail 313.

[0064] In this embodiment, there are four or more traveling wheels 312, which are arranged in pairs on both sides of the first crossbeam 311 to stably drive the turnout beam 20 to move.

[0065] In this embodiment, as Figure 7 As shown, the specific Figure 7 Figure b shows a schematic cross-sectional view of the auxiliary traveling device 32 in the Y direction; each of the auxiliary traveling devices 32 includes: a second crossbeam 321, a slider 322, and a sliding rail 323.

[0066] The sliding rail 323 is laid on the base platform 10 and extends along the Y direction. In this embodiment, the sliding rail 323 is an arc-shaped rail, and the opening of the arc-shaped rail faces the fixed support point 30, thereby facilitating the turnout beam 20 to turn around the fixed support point 30 and realize the turnout's lateral bending in the Y direction.

[0067] The second crossbeam 321 is connected to the turnout beam 20; in this embodiment, the second crossbeam 321 is detachably connected to the turnout beam 20 by a bolt assembly.

[0068] The slider 322 is connected to the second crossbeam 321 and can slide along the sliding rail 323. In this embodiment, there can be multiple sliders 322, which are disposed at the bottom of the second crossbeam 321. The sliders 322 can be made of wear-resistant material.

[0069] In another embodiment, such as Figure 8 As shown, the specific Figure 8 Figure a shows a Y-direction cross-sectional view of the main traveling device 31; each of the main traveling devices 31 includes: a first steel beam support leg 314, a traveling wheel 315, and a traveling rail 316.

[0070] The running track 316 is laid on the foundation platform 10 and extends along the Y direction. In this embodiment, the running track 316 is an arc-shaped track, and the opening of the arc-shaped track faces the fixed support point 30, thereby facilitating the turnout beam 20 to turn around the fixed support point 30 and realize the turnout's lateral bending in the Y direction.

[0071] The first steel beam support leg 314 is connected to the turnout beam 20. In this embodiment, as... Figure 9 As shown, the first steel beam support leg 314 is detachably connected to the turnout beam 20 via bolt assembly 22.

[0072] The traveling wheels 315 are connected to the first steel beam support leg 314 and can roll along the traveling rail 316. Specifically, there can be multiple traveling wheels 315, which are arranged in pairs at the bottom of the first steel beam support leg 314.

[0073] Specific Figure 8 Figure b shows a Y-direction cross-sectional view of the auxiliary traveling device 32; each of the auxiliary traveling devices 32 includes: a second steel beam support leg 324, a slider 325, and a sliding rail 326.

[0074] The sliding rail 326 is laid on the base platform 10 and extends along the Y direction. In this embodiment, the sliding rail 326 is an arc-shaped rail, and the opening of the arc-shaped rail faces the fixed support point 30, thereby facilitating the turnout beam 20 to turn around the fixed support point 30 and realize the turnout's lateral bending in the Y direction.

[0075] The second steel beam support leg 324 is connected to the turnout beam 20. In this embodiment, the second steel beam support leg 324 is detachably connected to the turnout beam 20 via a bolt assembly.

[0076] The slider 325 is connected to the second steel beam support leg 324 and can slide along the sliding rail 326. Specifically, there can be multiple sliders 325, which are arranged in pairs at the bottom of the second steel beam support leg 324. The sliders 325 can be made of wear-resistant material.

[0077] The traveling device provided in this embodiment no longer has a drive transmission assembly and a locking device installed. The movable traveling part of the traveling mechanism is a modular device that can be quickly disassembled and replaced.

[0078] In this embodiment, the drive transmission assembly 40 includes a push rod transmission assembly or a crank-rocker assembly. The drive transmission assembly in this embodiment uses a push rod transmission assembly or a crank-rocker assembly. The guide grooves that interact with the push rod and rocker are directly mounted on the turnout beam. This avoids wear and jamming similar to the complex shaft transmission systems of existing trolleys, and also effectively reduces the height of the running gear, increasing stability. It is understood that the crank-rocker assembly can be existing, and will not be described in detail here.

[0079] In this embodiment, as Figure 13 As shown, the push rod transmission assembly includes: a push rod motor 41, a lead screw 421, a push rod box 422, a transmission shaft 43, a roller 44, and a slide 45; the output end of the push rod motor 41 is connected to the lead screw 421 and is used to drive the lead screw 421 to rotate.

[0080] The push rod box 422 is sleeved on the lead screw 421 and extends and retracts along the Y direction through threaded transmission.

[0081] like Figure 10As shown, the chute 45 is provided on the foundation plate 21 of the turnout beam 20.

[0082] The drive shaft 43 is vertically mounted on the upper surface of the push rod box 422.

[0083] The roller 44 is disposed on the top end of the transmission shaft 43 and located within the groove 45; the roller 44 matches the groove 45; the roller 44 can rotate around the center line of the transmission shaft 43.

[0084] When the push rod motor 41 rotates, the push rod box 422 extends or shortens, and the transmission shaft 43 drives the roller 44 to move in the slide groove 45, completing the three-stage movement of unlocking, turning and locking in sequence, thereby pushing the turnout beam 20 to switch between the side line position and the straight position.

[0085] like Figure 12 As shown in this embodiment, Figure 12 As shown in Figures a and b, the slide groove 45 opens downwards; the slide groove 45 is Z-shaped and includes a turning groove section 452, with two unlocking groove sections located at both ends of the turning groove section 452 and connected to it (see reference). Figure 12 (Figure b, numerals 451 and 453); the switch groove section 452 extends along the X direction; the unlocking groove sections all extend along the Y direction; when the roller 44 moves within the unlocking groove section, it unlocks or locks the turnout beam 20 in the Y direction; when the roller 44 moves within the switch groove section 452, it pushes the turnout beam 20 to switch between the lateral position and the straight position.

[0086] It is understandable that when the push rod box 422 extends or retracts along the Y direction, the roller 44 rolls and translates along the Y direction within the unlocking groove section, thereby unlocking or locking the turnout beam 20 in the Y direction.

[0087] When the pusher box 422 continuously extends or shortens along the Y direction, the roller 44 experiences an X-direction force within the switch groove section 452, as well as a normal component force that causes the turnout beam 20 to move laterally towards the sideline position. The X-direction force allows the roller 44 to move along the X direction within the switch groove section 452. Under the action of the normal component force generated by the movement of the roller 44, the turnout beam 20 moves laterally, causing it to move towards the sideline position. That is, the X-direction movement of the roller relative to the slide is caused by the characteristics of the turnout beam switching process (the beam centerline has a small angle with the horizontal line, thus generating a normal component force).

[0088] In this embodiment, when the turnout changes from a straight position to a siding position, the roller 44 moves along... Figure 12 Move in the direction indicated by the middle arrow.

[0089] Please continue to refer to this. Figure 13As shown, in this embodiment, the push rod transmission assembly further includes: Support rail bases 47 are disposed on the base platform 10. In this embodiment, there can be multiple support rail bases 47, which are arranged at intervals along the Y direction on the base platform 10.

[0090] The push rod support rail 46 is mounted on the support rail base 47.

[0091] A motor base 48 is mounted on the base platform 10, and the push rod motor 41 is mounted on the motor base 48. The push rod motor 41 is used to drive the push rod box 422 to extend or retract along the Y direction.

[0092] A push rod limit switch 49 is mounted on the base platform 10.

[0093] The push rod contact 410 is disposed on the lower surface of the push rod box 422.

[0094] When the push rod box 422 extends or retracts to a predetermined position, the push rod contact 410 contacts the limit switch 49, triggering the push rod motor 41 to stop operating.

[0095] Combination Figure 10 , Figure 11 , Figure 14b and Figure 15b As shown, the first locking component 51 and the second locking component 52 are located on both sides of the centerline of the turnout beam 20, and are arranged anti-symmetrically. The locking device in this embodiment is arranged on both sides of the turnout centerline. This design significantly enhances the stiffness of the turnout beam in the Y direction, making the turnout more stable when subjected to Y-direction loads, that is, improving the stiffness of the Y-direction system.

[0096] Combination Figure 10 , Figure 11 (Specifically as follows) Figure 11 (Figure a) Figure 14a and Figure 14b As shown, in this embodiment, the first locking component 51 includes a first locking hook 512, which is hinged to the base plate 21 of the turnout beam 20 via a first rotating shaft 516.

[0097] The lower surface of the first locking hook 512 is provided with an upwardly recessed first unlocking groove 517, and its upper surface is provided with a downwardly recessed first limiting groove 519; specifically, the upper surface of the first locking hook 512 may also be provided with a downwardly recessed first sensor groove 518, the first sensor groove 518 and the first limiting groove 519 are spaced apart, and the first sensor groove 518 is located near the free end d1 of the first locking hook 512.

[0098] The first locking pad 514 is disposed on the upper surface of the push rod box 422 of the push rod transmission assembly; The first base 53 is mounted on the base platform 10.

[0099] The first locking frame 511 is mounted on the first base 53 at its bottom end.

[0100] The first locking limit block 513 is disposed on the first locking frame 511; the first locking sensor 515 is disposed on the first locking frame 511; when the first locking assembly 51 is in the locked state, the first locking pad 514 is located at the bottom of the free end d1 of the first locking hook 512, supporting the free end d1 of the first locking hook 512, the first locking hook 512 is in a horizontal state, the first locking sensor 515 is located in the first sensor groove 518, and the first locking limit block 513 is located in the first limiting groove 519, that is, the first locking limit block 513 cooperates with the first limiting groove 519 on the upper surface of the first locking hook 512, and the turnout beam 20 is locked.

[0101] When the first locking component 51 is in the unlocked state, the push rod motor 41 rotates, causing the lead screw 421 to rotate accordingly. The push rod box 422 extends along the push rod support rail 46, and the roller 44 and the first locking pad 514 move along the Y-axis with the push rod box 422. When the roller 44 moves relative to the first lock hook 512 along the Y-axis of the slide groove 45, the first locking pad 514 slides into the first unlocking groove 517 on the lower surface of the first locking hook 512. The first locking hook 512 falls freely around the first locking hook pivot 516 under the action of gravity, and at the same time, the first locking hook 512 releases contact with the first locking limiter 513 and the first locking sensor 515, thus beginning the unlocking process. The push rod box 422 continues to extend along the push rod support rail 46, and the positional relationship between the first locking pad 514 and the first unlocking groove 517 on the lower surface of the first locking hook 512 is maintained.

[0102] Combination Figure 10 , Figure 11 (Specifically as follows) Figure 11 (Figure b in the text) Figure 15a and Figure 15b As shown, the second locking component 52 includes: a second locking hook 522, which is hinged to the base plate 21 of the turnout beam 20 via a second rotating shaft 526; the first locking hook 512 and the second locking hook 522 are arranged anti-symmetrically.

[0103] Specifically, it can be understood that the first locking component 51 and the second locking component 52 are related to Figure 10 The CC section shown is arranged anti-symmetrically. That is, the first locking hook 512 and the second locking hook 522 are about... Figure 10 The CC section shown is arranged in an anti-symmetrical manner.

[0104] The lower surface of the second locking hook 522 is provided with an upwardly recessed second unlocking groove 527, and its upper surface is provided with a downwardly recessed second limiting groove 529.

[0105] Specifically, the upper surface of the second locking hook 522 may also be provided with a downwardly recessed second sensor groove 528, the second sensor groove 528 and the second limiting groove 529 are spaced apart, and the second sensor groove 528 is located near the free end d2 of the second locking hook 522.

[0106] The second locking pad 524 is disposed on the upper surface of the push rod box 422 of the push rod transmission assembly; The second base 54 is disposed on the base platform 10.

[0107] The second locking frame 521 is disposed at its bottom end on the second base 54 of the first locking assembly 51.

[0108] The second locking limit block 523 is disposed on the second locking frame 521.

[0109] The second locking sensor 525 is disposed on the second locking bracket 521.

[0110] When the second locking component 52 is in the locked state, the second locking limit block 523 is located in the second limit groove 529, the second locking sensor 525 is located in the second sensor groove 528, and the second locking pad 524 is located at the bottom of the free end d2 of the second locking hook 522, supporting the free end d2 of the second locking hook 522.

[0111] The push rod transmission assembly is linked with the first locking assembly 51 and the second locking assembly 52. ​​The stroke of the push rod box 422 of the push rod transmission assembly controls the first locking assembly 51 and the second locking assembly 52 to unlock, switch, and lock the turnout beam 20.

[0112] like Figure 11 Chinese C diagram and Figure 12 As shown in Figures a and b, the connection points of the first locking hook 512 and the second locking hook 522 with the foundation plate of the turnout beam are respectively located on the center line of the turnout beam (e.g., ...). Figure 12 (As shown by the dashed line in Figure a) on both sides, and located outside the unlocking groove section of the slide groove 45, close to the slide groove 45, the free end of the first locking hook 512 faces the opposite direction to the free end of the second locking hook 522.

[0113] The drive shaft 43, the first locking pad 514, and the second locking pad 524 are fixedly mounted on the upper surface of the push rod box 422. The unlocking distance of the slide groove 45 is consistent with the distance between the drive shaft 43 and the first locking pad 514 (or the second locking pad 524). The turning distance of the slide groove 45 is consistent with the longitudinal coordinate change of the turnout beam at that position during the turning process. The unlocking distance of the slide groove 45 is consistent with the distance between the drive shaft 43 and the second locking pad 524 (or the first locking pad 514). Through the above settings, the linkage of turnout unlocking, turning, and locking is ensured during the movement of the push rod motor 41 and the push rod box 422.

[0114] The following example illustrates the working principle of the turnout in the above embodiment to better understand its operation.

[0115] like Figure 16 As shown, where, Figure 16 Figure a shows the state diagram of the first locking component 51 and the push rod transmission component when the turnout is in a straight position and in a straight locking state.

[0116] Straight position locked state: When the turnout is in such a state Figure 5 When the turnout beam 20 is in the straight line position shown in Figure b, its centerline is a straight line. The turnout beam 20 is locked by the first locking assembly 51. The push rod motor 41 of the push rod transmission assembly does not rotate, and the push rod 422 is in its initial position and does not extend. The bottom of the free end d1 of the first locking hook 512 of the first locking assembly 51 is supported by the first locking pad 514, and the first locking hook 512 locks the turnout beam 20.

[0117] Figure 16 Figure b in the figure is a schematic diagram of the state of the first locking component 51 and the push rod transmission component when the turnout is in the straight position and in the straight unlock state; During the unlocking phase: the push rod motor 41 rotates forward, and the lead screw 421 rotates accordingly; the push rod box 422 extends along the push rod support rail 46, the roller 44 moves in the Y direction in the slide groove 45, the first locking pad 514 slides from the bottom of the free end of the first locking hook 512 into the first unlocking groove of the first locking hook 512, and the first locking hook 512 falls and unlocks under the action of gravity.

[0118] Figure 16 Figure c in the figure is a schematic diagram of the state of the first locking component 51 and the push rod transmission component when the turnout is switching. Figure 16 Figure d in the diagram shows the state of the second locking component 52 and the push rod transmission component when the turnout continues to switch. During the switching phase: the push rod box 422 continues to extend, and the roller 44 moves along the X direction within the slide groove 45, pushing the turnout beam 20 to switch around the fixed fulcrum 30. At this time, the first locking pad 514 is still located in the first unlocking groove of the first locking hook 512, so that the first locking component 51 remains in the unlocked state; when it is close to the predetermined position, the second locking pad 524 slides from the bottom of the non-free end of the second locking hook 522 into the second unlocking groove, at which time the second locking component 52 remains in the unlocked state.

[0119] Figure 16 Figure e in the figure is a schematic diagram of the state of the second locking component 51 and the push rod transmission component when the turnout is switched to the predetermined position; When the turnout reaches the predetermined position, it enters the locking stage: the push rod box 422 extends further, the roller 44 moves along the Y direction within the slide groove 45, the second locking pad 524 slides from the second unlocking slot of the second locking hook 522 into the bottom of the free end of the second locking hook 522, the second locking hook 522 engages upwards and contacts the second locking sensor 525, the push rod contact 410 of the push rod box 422 contacts the push rod limit switch 49, the push rod motor 41 stops running, the push rod box 422 stops extending, and the locking is completed. At this time, the turnout is in the siding position, realizing the track change from the straight position to the siding position.

[0120] It is understood that the aforementioned Y-direction movement can be the lateral movement of the turnout, which is not a linear movement in the Y-direction in the narrow sense. The lateral movement trajectory of the turnout is actually curved, similar to the curved shape of the sliding rail along the running rail, but the present invention is not limited thereto.

[0121] When the turnout changes direction in the XY plane, the linear coordinates of any point on the turnout beam 20 (X... Z ,Y Z ) and lateral line position coordinates (X C ,Y C ), there exists X Z >X C Y Z <Y C .

[0122] When the turnout returns from the siding position to the straight position, the process is the reverse of the above process, as follows: During the unlocking stage: when the motor 41 moves in the opposite direction, the push rod box 422 retracts along the push rod support rail 46, the roller 44 moves in the Y direction in the slide groove 45, the second locking pad 524 slides from the bottom of the free end of the second locking hook 522 into the second unlocking groove of the second locking hook 522, and the second locking hook 522 falls and unlocks under the action of gravity.

[0123] During the switching phase: the push rod box 422 continues to retract, and the roller 44 moves along the X direction in the slide groove 45, pushing the turnout beam 20 to switch around the fixed support point 30.

[0124] During the locking phase: the push rod box 422 retracts further, the roller 44 moves along the Y direction in the slide groove 45, the first locking pad 514 slides from the first unlocking groove of the first locking hook 512 into the bottom of the free end of the first locking hook 512, the first locking hook 512 snaps upward and contacts the first locking sensor 515, the push rod contact 410 of the push rod box 422 contacts the push rod limit switch 49, the push rod motor 41 stops running, the push rod box 422 stops retracting, and the locking is completed.

[0125] It is understandable that the specific process of the above-mentioned turnout unlocking-switching-locking stage reflects that the locking device 50 and the drive transmission component 40 work together to achieve turnout unlocking-switching-locking. Compared with the existing turnouts that require a separate driving device for the locking device 50, and where both unlocking and locking must rely on the driving force of the separate driving device, this improves the operating efficiency of trains in railway systems that operate for long periods of time.

[0126] The advantages of this invention compared to the prior art are shown in the table below: In summary, the present invention provides a novel conventional high-speed maglev turnout, mainly comprising a turnout beam, a fixed support point and multiple running devices, several drive transmission components, several locking devices, and a foundation platform.
