[0031] Compared with the prior art, the present invention has at least the following technical effects:

[0032] The present invention provides a novel conventional high-speed maglev turnout, comprising a turnout beam, a fixed fulcrum, multiple running gears, drive transmission components, locking devices, and a base platform. This invention effectively improves system stability and rigidity, reduces mechanical wear, enhances operational efficiency, and facilitates inspection and maintenance.

[0033] Specifically, the locking device of the present invention adopts a mechanical locking method, and realizes the locking-switching-unlocking action by driving the transmission component and the locking device in linkage. Compared with the prior art, there is no need to set a power device for the locking device, which saves costs, reduces the difficulty of system control, greatly saves the time required for the turnout switching action ("unlocking-switching-locking"), and improves the operating efficiency of the entire railway system, that is, improves the operating efficiency of the maglev train.

[0034] The locking devices of the present invention are arranged on both sides of the center line of the turnout. This design significantly enhances the stiffness of the turnout beam in the Y direction, making the turnout more stable when bearing Y-direction loads, that is, improving the Y-direction system stiffness.

[0035] Compared to existing turnout trolleys, the running gear of this invention features a simplified design. Its simple structure solely serves the running function, eliminating the need for drive transmission components and locking devices. This change reduces wear and jamming associated with complex shafting, thereby reducing mechanical wear and extending the running gear's service life.

[0036] The drive transmission assembly and the locking device are no longer installed on the running device; the overall height (the height perpendicular to the XY plane) of the turnout of the present invention can be reduced and the stability can be increased.

[0037] In addition, the running device of the present invention includes an auxiliary running device to further improve the vertical (perpendicular to the XY plane) rigidity.

[0038] The present invention is provided with a basic platform, including the entire turnout working range. Compared with the prior art in which the turnouts are set on separate piers and only an operating platform is provided on the piers, which makes it inconvenient to maintain and repair the entire turnout, the entire basic platform of the present invention can be used as an operating platform, which facilitates the maintenance and repair of the entire turnout, as well as the evacuation of personnel in special circumstances.

[0039] The drive transmission assembly of the present invention adopts a push rod transmission assembly or a crank rocker assembly, and the guide groove that interacts with the push rod and the rocker is directly installed on the turnout beam, thereby avoiding wear and jamming of the complex shaft system transmission similar to that of existing trolleys, and effectively reducing the height of the running device and increasing stability.

DETAILED DESCRIPTION

[0061] The following is a further detailed description of a conventional high-speed maglev traffic turnout proposed by the present invention in conjunction with the accompanying drawings and specific embodiments. According to the following description, the advantages and features of the present invention will be clearer. It should be noted that the drawings are in a very simplified form and use non-precise proportions, which are only used to conveniently and clearly assist in explaining the purpose of the embodiments of the present invention. In order to make the purpose, features and advantages of the present invention more obvious and easy to understand, please refer to the drawings. It should be noted that the structure, proportion, size, etc. illustrated in the drawings of this specification are only used to match the content disclosed in the specification for people familiar with this technology to understand and read, and are not used to limit the implementation conditions of the present invention, so they have no technical substantive significance. Any modification of the structure, change in the proportional relationship or adjustment of the size should still fall within the scope of the technical content disclosed by the present invention without affecting the efficacy and purpose that can be achieved by the present invention.

[0062] As described in the background art, on the existing trolley, it is necessary to set up a switch device and a lock pin device that operate independently, which makes the mechanical structure complicated and reduces the operating efficiency of the maglev train. Specifically, Figure 1 As shown, Figure 1 Figure b in the middle is a top view of the existing conventional high-speed maglev turnout without the turnout beam; Figure 1 Figure a in the middle is a schematic diagram of the side structure of the existing conventional high-speed maglev turnout in the X direction. Figure 1 As shown in Figures a and b, the commonly used high-speed maglev turnouts in China are integrally elastic side-bending turnouts. Turnout beam 0 is a continuous steel beam supported by a fixed crossbeam 1 and five in-plane movable trolleys 2. These beams are mounted on six independently positioned piers Z0 to Z5. Turnout beam 0 is connected to the trolleys 2 via bolts.

[0063] All the trolleys 2 of the buttresses Z1 to Z5 are equipped with a locking pin device 3 and a running device 4 . The trolleys 2 of the buttresses Z3 and Z5 are also equipped with a driving motor 6 and a transmission gear 7 .

[0064] like Figure 2 As shown, after the locking pin device 3 and the running 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 2.645 m, which reduces the stability of the existing turnout.

[0065] Please continue to refer to Figure 2 As shown, it gives Figure 1 In Figure a, the AA cross-section of buttress Z1 is shown. The trolleys 2 of buttresses Z1, Z2, and Z4 are all equipped with locking pins 3, running gear 4, and drive shaft 5. The running gear 4 includes running wheels mounted on the drive shaft 5. The drive shaft 5 extends in the X direction, and the running wheels move generally in the Y direction.

[0066] like Figure 3 As shown, Figure 1 In the diagram (b), the CC cross-section of buttress Z5 is shown. In addition to the running wheels of the running mechanism 4, the locking pin 3, and the transmission shaft 5, the trolley 2 of buttresses Z3 and Z5 also houses a drive motor 6 and a transmission gear 7. The drive motor 6 drives the transmission shaft 5. The running wheels and transmission gear 7 share the same transmission shaft 5, resulting in complex loads and difficult maintenance.

[0067] like Figure 4 shown, and Figure 1 As shown in Figure (a), at piers Z1 through Z5, a locking pin device 3 and a locking pin motor 9 are installed at the centerline of all trolleys 2 at these piers. The corresponding locking device 8 is mounted on the ground. Rotating the locking pin motor 9 causes the locking pin device 3 to move backward, away from the locking device 8, unlocking the piers. Reverse rotation of the locking pin motor 93 causes the locking pin device 3 to move forward, inserting into the locking device 8 and locking the piers in the Y direction.

[0068] When the turnout is changed, first, the lock pin motor 9 of the lock pin device 3 of piers Z1 to Z5 works, the lock pin rod 3-1 is pulled out, and the turnout is unlocked; then, the drive motor 6 on piers Z3 and Z5 works, and the transmission shaft 5, transmission gear 7 and running wheel push the trolley 2 and drive the turnout beam 0-0 to switch until it reaches the designed target position; finally, the lock pin motor 9 works in the reverse direction, and the lock pin rod 3-1 of the lock pin device 3 extends to the locking device 8, and the turnout is locked.

[0069] This type of existing turnout has the following problems: (1) The turnout switching action is to unlock the lock pin device 3 by driving the separate lock pin motor 9, then drive the transmission shaft 5 and the running wheel 4 by the drive motor 6 to rotate the turnout, and then lock the lock pin device 3 by driving the lock pin motor 9. The entire turnout switching time is relatively long. (2) The running, locking pin and driving devices are installed on the trolley, with a total height of 2.65m, and the system stability is poor. (3) The trolley combines the running, driving transmission and locking functions, so the mechanical transmission and running components are prone to jamming, wear and other problems during the turnout switching process. (4) The lateral (Y-direction) locking target is achieved by the lock 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 pier position, which is not conducive to the daily maintenance and inspection of the entire turnout, nor is it conducive to the setting of evacuation passages.

[0070] like Figure 5 As shown, Figure 5 Figure a in the middle shows a top view of the turnout at the siding position. Figure 5 FIG. b in FIG. 2 is a schematic diagram of a top view of a turnout in a straight line position; a conventional high-speed maglev traffic turnout provided in this embodiment includes: a turnout beam 20, which is formed by connecting a plurality of steel beam sections to form an integral continuous steel beam, wherein the turnout beam 20 is in a straight line position (such as Figure 5 As shown in Figure b, when the turnout beam 20 is in a straight line, its length direction is the X direction, its width direction is the Y direction, and its height direction is the Z direction, thereby forming a three-dimensional coordinate system.

[0071] The fixed support point 30 is used to fix and support one end of the switch beam 20 so that the switch beam 20 can realize Y-direction switching in the XY plane around the fixed support point 30 .

[0072] Multiple running devices (see Figure 5 31 and 32 ), are arranged below the switch beam 20 at intervals along the X direction to support the switch beam 20 .

[0073] At least one drive transmission assembly 40 is arranged below the switch beam 20 at intervals along the X direction, and is used to provide switching driving force for the switch beam 20. In this embodiment, there can be multiple drive transmission assemblies 40.

[0074] At least one locking device 50 is arranged below the switch beam 20 at intervals along the X-direction. The locking device 50 is linked to the drive transmission assembly 40 and is used to unlock and lock the switch beam 20 under the drive of the drive transmission assembly 40. In this embodiment, the number of the locking devices 50 is the same as the number of the drive transmission assemblies 40, and they can be provided in combination with the drive transmission assembly 40.

[0075] The locking device 50 includes a first locking assembly 51 and a second locking assembly 52, which are used to mechanically lock the turnout beam 20 in a straight position and a siding position, respectively.

[0076] The basic platform 10 is used to support the switch beam 20, the running device, the drive transmission assembly 40 and the locking device 50.

[0077] This embodiment can effectively improve system stability and system rigidity, reduce mechanical wear, improve operating efficiency, and facilitate inspection and maintenance.

[0078] Specifically, the locking device of this embodiment adopts a mechanical locking method, and realizes the unlocking, switching and locking actions of the turnout beam by driving the transmission component and the locking device in linkage. Compared with the existing technology, there is no need to set a power device for the locking device, which saves costs, reduces the difficulty of system control, greatly saves the time required for the turnout switching action ("unlock-switch-lock"), and improves the operating efficiency of the entire railway system.

[0079] Compared to existing turnout trolleys, the running gear of this embodiment features a simplified design. Its simple construction solely serves the running function, and the drive transmission assembly and locking device are no longer installed on the running gear. This change reduces wear and jamming associated with complex shafting, thereby reducing mechanical wear and extending the running gear's service life. The drive transmission assembly and locking device are no longer installed on the running gear, reducing the overall height of the turnout of this embodiment to below the existing height of h = 2.645m, thereby increasing its stability.

[0080] This embodiment is provided with a basic platform, including the entire turnout working range. Compared with the prior art, the turnouts are set on separate piers, and only an operating platform is provided on the piers, which makes it inconvenient to maintain and repair the entire turnout. In this embodiment, the entire basic platform can be used as an operating platform, which facilitates the maintenance and repair of the entire turnout, as well as the evacuation of personnel in special circumstances.

[0081] like Figure 6 As shown, this embodiment further includes a base 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 base plate 21 .

[0082] It can be understood that the base plate 21 is provided in sections, that is, the base plate 21 is provided only at the position of the turnout beam 20 where the drive transmission assembly 40 and the locking device 50 are provided.

[0083] Please continue to refer to Figure 5 As shown, in this embodiment, the plurality of running devices include a plurality of main running devices 31 and auxiliary running devices 32. The plurality of main running devices 31 and auxiliary running devices 32 are arranged in an intersecting manner along the X-direction below the turnout beam 20. The running device provided in this embodiment includes auxiliary running devices, further improving vertical stiffness (perpendicular to the XY plane).

[0084] In one embodiment, Figure 7 As shown, the specific Figure 7 Figure a shows a Y-direction cross-sectional schematic diagram of the main running device 31; each of the main running devices 31 includes: a first crossbeam 311, a running wheel 312 and a running rail 313; the running rail 313 is laid on the basic platform 10 and extends along the Y-direction.

[0085] In this embodiment, the running rail 313 is an arc-shaped rail, and the arc-shaped rail opening faces the fixed support point 30, thereby facilitating the turnout beam 20 to switch around the fixed support point 30 and realize the lateral bending of the turnout in the Y direction.

[0086] The first crossbeam 311 is connected to the switch beam 20. In this embodiment, the first crossbeam 311 is detachably connected to the switch beam 20 via a bolt assembly.

[0087] The running wheel 312 is rotatably connected to the first beam 311 and can roll along the running rail 313 .

[0088] In this embodiment, the number of the running wheels 312 is greater than or equal to 4, and they are arranged in pairs on both sides of the first crossbeam 311 to stably drive the switch beam 20 to move.

[0089] In this embodiment, if Figure 7 As shown, the specific Figure 7 Figure b shows a Y-axis cross-sectional view of the auxiliary running device 32 ; each of the auxiliary running devices 32 includes: a second crossbeam 321 , a slider 322 and a sliding rail 323 .

[0090] 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 is toward the fixed support point 30, thereby facilitating the turnout beam 20 to switch around the fixed support point 30 and realize the lateral bending of the turnout in the Y direction.

[0091] The second crossbeam 321 is connected to the switch beam 20 ; in this embodiment, the second crossbeam 321 is detachably connected to the switch beam 20 via a bolt assembly.

[0092] The slider 322 is connected to the second crossbeam 321 and can slide along the slide rail 323. In this embodiment, there can be multiple sliders 322, which are arranged at the bottom of the second crossbeam 321. The sliders 322 can be made of wear-resistant materials.

[0094] The running rail 316 is laid on the base platform 10 and extends along the Y direction. In this embodiment, the running rail 316 is an arc-shaped rail, and the opening of the arc-shaped rail is toward the fixed support point 30, thereby facilitating the turnout beam 20 to switch around the fixed support point 30 and realize the lateral bending of the turnout in the Y direction.

[0095] The first steel beam leg 314 is connected to the turnout beam 20. Figure 9 As shown, the first steel beam leg 314 is detachably connected to the turnout beam 20 via the bolt assembly 22 .

[0096] The running wheels 315 are connected to the first steel beam legs 314 and can roll along the running rails 316. Specifically, there can be multiple running wheels 315, which are arranged in pairs at the bottom of the first steel beam legs 314.

[0097] Specific Figure 8 Figure b shows a Y-section schematic diagram of the auxiliary running device 32; each of the auxiliary running devices 32 includes: a second steel beam support leg 324, a slider 325 and a sliding rail 326.

[0098] 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 a curved rail with an opening toward the fixed support point 30, thereby facilitating the turnout beam 20 to switch around the fixed support point 30 and realize lateral bending of the turnout in the Y direction.

[0099] The second steel beam leg 324 is connected to the switch beam 20. In this embodiment, the second steel beam leg 324 is detachably connected to the switch beam 20 by a bolt assembly.

[0100] The slider 325 is connected to the second steel beam leg 324 and can slide along the slide rail 326. Specifically, there can be multiple sliders 325, which are arranged in pairs at the bottom of the second steel beam leg 324. The sliders 325 can be made of wear-resistant material.

[0101] The running device provided in this embodiment no longer has a drive transmission assembly and a locking device installed. The movable running part of the running mechanism is a modular device that can be quickly disassembled and replaced.

[0102] In this embodiment, the drive transmission assembly 40 comprises a push rod transmission assembly or a crank rocker assembly. In this embodiment, the drive transmission assembly employs a push rod transmission assembly or a crank rocker assembly. The guide grooves interacting with the push rod and rocker are directly mounted on the turnout beam. This avoids wear and jamming associated with complex shafting systems found in existing trolleys, effectively reduces the height of the running gear, and enhances stability. It is understood that the crank rocker assembly can be an existing one and will not be further described here.

[0103] In this embodiment, if Figure 13 As shown, the push rod transmission assembly includes: a push rod motor 41, a screw rod 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 screw rod 421 for driving the screw rod 421 to rotate.

[0104] The push rod box 422 is sleeved on the screw rod 421 and is extended and retracted along the Y direction through thread transmission.

[0105] like Figure 10 As shown, the chute 45 is arranged on the base bottom plate 21 of the turnout beam 20 .

[0106] The transmission shaft 43 is vertically disposed on the upper surface of the push rod box 422 .

[0107] The roller 44 is disposed on the top end of the transmission shaft 43 and is located in the slide groove 45 ; the roller 44 matches the slide groove 45 ; and the roller 44 can rotate around the center line of the transmission shaft 43 .

[0108] 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 45, completing the three-stage movement of unlocking, switching and locking in sequence, thereby pushing the turnout beam 20 to switch between the siding position and the straight position.

[0109] like Figure 12 As shown, in this embodiment, Figure 12As shown in Figures a and b, the chute 45 opens downward; the chute 45 is Z-shaped, including a switch groove section 452, two unlocking groove sections located at both ends of the switch groove section 452 and connected thereto (reference Figure 12 (in figure b, reference 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 in the unlocking groove section, the Y direction unlocking or locking of the turnout beam 20 is achieved; when the roller 44 moves in the switch groove section 452, it pushes the turnout beam 20 to switch between the siding position and the straight position.

[0110] It can be understood that when the push rod box 422 is extended or shortened along the Y direction, the roller 44 rolls and translates along the Y direction in the unlocking groove section, thereby achieving Y-direction unlocking or locking of the turnout beam 20.

[0111] When the push rod box 422 continues to extend or contract in the Y direction, the roller 44 generates an X-direction force component within the switch groove section 452, as well as a normal force component that causes the switch beam 20 to move laterally toward the siding. The X-direction force component enables the roller 44 to move in the X direction within the switch groove section 452. The switch beam 20, under the action of the normal force component generated by the movement of the roller 44, moves laterally toward the siding. In other words, the X-direction movement of the roller relative to the chute is caused by the characteristics of the switch beam switching process (the beam centerline forms a small angle with the horizontal, which generates a normal force component).

[0112] In this embodiment, when the turnout switches from the straight position to the siding position, the roller 44 moves along the Figure 12 Move in the direction indicated by the arrow.

[0113] Please continue to refer to Figure 13 As shown, in this embodiment, the push rod transmission assembly further includes:

[0114] The support rail foundation 47 is provided on the basic platform 10. In this embodiment, there may be a plurality of support rail foundations 47, which are arranged on the basic platform 10 at intervals along the Y direction.

[0115] The push rod support rail 46 is arranged on the support rail base 47 .

[0116] The motor base 48 is provided on the base platform 10, and the push rod motor 41 is provided 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.

[0117] The push rod travel switch 49 is arranged on the basic platform 10 .

[0118] The push rod contact 410 is provided on the lower surface of the push rod box 422 .

[0119] When the push rod box 422 is extended or retracted to a predetermined position, the push rod contact 410 contacts the travel switch 49, triggering the push rod motor 41 to stop running.

[0120] Combine Figure 10 、 Figure 11 、 Figure 14b and Figure 15b As shown, the first locking assembly 51 and the second locking assembly 52 are located on either side of the centerline of the turnout beam 20, and are arranged antisymmetrically. The placement of the locking devices on either side of the turnout centerline significantly enhances the Y-axis stiffness of the turnout beam, making the turnout more stable when subjected to Y-axis loads, thereby improving the Y-axis system stiffness.

[0121] Combine Figure 10 、 Figure 11 (Specifically, Figure 11 Figure a in the figure), Figure 14a and Figure 14b As shown, in this embodiment, the first locking assembly 51 includes: a first locking hook 512, which is hinged to the base bottom plate 21 of the turnout beam 20 through a first rotating shaft 516.

[0122] The lower surface of the first lock hook 512 is provided with a first unlocking groove 517 which is recessed upward, and the upper surface thereof is provided with a first limiting groove 519 which is recessed downward; specifically, the upper surface of the first lock hook 512 may also be provided with a first sensor groove 518 which is recessed downward, and the first sensor groove 518 and the first limiting groove 519 are spaced apart, and the first sensor groove 518 is provided close to the free end d1 of the first lock hook 512.

[0123] a first locking pad 514 , which is disposed on the upper surface of the push rod box 422 of the push rod transmission assembly;

[0124] The first base 53 is disposed on the basic platform 10 .

[0125] The first locking frame 511 has its bottom end disposed on the first base 53 .

[0126] The first locking limit block 513 is arranged on the first locking frame 511; the first locking sensor 515 is arranged on the first locking frame 511; when the first locking assembly 51 is in a 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 slot 518, and the first locking limit block 513 is located in the first limiting slot 519, that is, the first locking limiter 513 cooperates with the first limiting slot 519 on the upper surface of the first locking hook 512, and the turnout beam 20 is locked.

[0127] When the first locking assembly 51 is in the unlocked state, the push rod motor 41 rotates, causing the screw 421 to rotate accordingly. The push rod housing 422 extends along the push rod support rail 46, and the roller 44 and the first locking pad 514 move along the Y-direction with the push rod housing 422. As the roller 44 moves relative to the Y-direction of the chute 45, the first locking pad 514 slides into the first unlocking groove 517 on the lower surface of the first locking hook 512. Under the force of gravity, the first locking hook 512 freely falls about the first locking hook rotation axis 516. Simultaneously, the first locking hook 512 releases contact with the first locking stopper 513 and the first locking sensor 515, and unlocking begins. The push rod housing 422 continues to extend along the push rod support rail 46, and the first locking pad 514 maintains its positional relationship with the first unlocking groove 517 on the lower surface of the first locking hook 512.

[0128] Combine Figure 10 、 Figure 11 (Specifically, Figure 11 Figure b), Figure 15a and Figure 15b As shown, the second locking assembly 52 includes: a second locking hook 522, which is hinged to the base bottom plate 21 of the turnout beam 20 through a second rotating shaft 526; the first locking hook 512 and the second locking hook 522 are anti-symmetrically arranged.

[0129] Specifically, it can be understood that the first locking component 51 and the second locking component 52 are Figure 10 The CC section shown is arranged antisymmetrically. That is, the first locking hook 512 and the second locking hook 522 are arranged antisymmetrically. Figure 10 The CC sections shown are arranged antisymmetrically.

[0130] The second locking hook 522 has a second unlocking groove 527 recessed upwardly on its lower surface, and a second limiting groove 529 recessed downwardly on its upper surface.

[0131] Specifically, a second sensor groove 528 that is recessed downwards may be further provided on the upper surface of the second locking hook 522 . The second sensor groove 528 and the second limiting groove 529 are spaced apart, and the second sensor groove 528 is provided close to the free end d2 of the second locking hook 522 .

[0132] a second locking pad 524 disposed on the upper surface of the push rod box 422 of the push rod transmission assembly;

[0133] The second base 54 is disposed on the basic platform 10 .

[0134] The second locking frame 521 has its bottom end disposed on the second base 54 of the first locking assembly 51 .

[0135] The second locking limit block 523 is disposed on the second locking frame 521 .

[0136] The second locking sensor 525 is disposed on the second locking frame 521 .

[0137] When the second locking assembly 52 is in a 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.

[0138] The push rod transmission assembly is linked with the first locking assembly 51 and the second locking group 52, and the first locking assembly 51 and the second locking assembly 52 are controlled by the stroke of the push rod box 422 of the push rod transmission assembly to unlock, switch and lock the turnout beam 20.

[0139] like Figure 11 Figure C 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 base plate of the turnout beam are respectively located on the center line of the turnout beam (such as Figure 12 (as shown by the dotted line in Figure a) on both sides, and located on the outside of the unlocking groove section of the slide 45, close to the slide 45, the free end of the first lock hook 512 is facing opposite to the free end of the second lock hook 522.

[0140] The transmission shaft 43, first locking pad 514, and second locking pad 524 are fixedly mounted on the upper surface of the push rod housing 422. The unlocking distance of the chute 45 is consistent with the distance between the transmission shaft 43 and the first locking pad 5-14 (or second locking pad 5-24). The switching distance of the chute 45 is consistent with the change in the longitudinal coordinate of the turnout beam at that location during the switching process. The unlocking distance of the chute 45 is consistent with the distance between the transmission shaft 43 and the second locking pad 524 (or first locking pad 514). This arrangement ensures that the turnout unlocks, switches, and locks in unison as the push rod motor 41 moves the push rod housing 422.

[0141] The following example illustrates the working principle of the turnout in the above embodiment for better understanding.

[0142] like Figure 16 As shown, Figure 16 Figure a in FIG is a schematic diagram of the state of the first locking assembly 51 and the push rod transmission assembly when the turnout is in a straight position and in a straight locking state.

[0143] Linear position locking state: When the turnout is in the following Figure 5 In the straight position shown in Figure (b), the centerline of the switch beam 20 is a straight line. The switch beam 20 is locked using the first locking assembly 51. The push rod motor 41 of the push rod transmission assembly is not rotating, and the push rod 422 is in its initial position and not extended. 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 switch beam 20.

[0144] Figure 16 Figure b is a schematic diagram of the first locking assembly 51 and the push rod transmission assembly when the turnout is in a straight position and in a straight unlocked state;

[0145] In the unlocking stage: the push rod motor 41 rotates forward, and the screw rod 421 rotates accordingly; the push rod box 422 extends along the push rod support rail 46, and the roller 44 moves along the Y direction in the slide groove 45, and 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 is unlocked under the action of gravity.

[0146] Figure 16 Figure c is a schematic diagram of the first locking assembly 51 and the push rod transmission assembly when the turnout is switching;

[0147] Figure 16 Figure d is a schematic diagram of the state of the second locking assembly 52 and the push rod transmission assembly when the turnout continues to switch;

[0148] During the switching phase, the push rod box 422 continues to extend, and the roller 44 moves in the X-direction within the chute 45, pushing the switch beam 20 to switch about the fixed fulcrum 30. At this time, the first locking pad 514 remains in the first unlocking slot of the first locking hook 512, so that the first locking assembly 51 remains unlocked. When the first locking pad 524 is about to reach the predetermined position, it slides from the bottom of the non-free end of the second locking hook 522 into the second unlocking slot, and the second locking assembly 52 remains unlocked.

[0149] Figure 16 Figure e in FIG is a schematic diagram of the state of the second locking assembly 51 and the push rod transmission assembly when the switch is switched to a predetermined position;

[0150] When the switch reaches the predetermined position, it enters the locking stage: the push rod box 422 extends further, the roller 44 moves in the Y direction within the chute 45, and 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 upward and contacts the second locking sensor 525. The push rod contact 410 of the push rod box 422 contacts the push rod travel switch 49, the push rod motor 41 stops running, and the push rod box 422 stops extending, completing the locking. At this point, the switch is in the siding position, completing the line change from the straight line position to the siding position.

[0151] It can be understood that the above-mentioned Y-direction movement can be the lateral movement of the switch, which is not the narrow Y-direction linear movement. The lateral movement trajectory of the switch is actually curved, and the curved shape along the running rail and sliding rail is similar, but the present invention is not limited to this.

[0152] When the turnout switches in the XY plane, the linear position coordinates (X Z ,Y Z ) and lateral position coordinates (X C ,Y C ), there exists X Z >X C , Y Z <Y C .

[0153] When the switch returns to the straight position from the siding position, the process is opposite to the above process, as follows: in 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, and the roller 44 moves along the Y direction in the slide groove 45, and the second locking pad 524 slides from the bottom of the free end of the second lock hook 522 into the second unlocking groove of the second lock hook 522, and the second lock hook 522 falls and is unlocked under the action of gravity.

[0154] During the switching stage, the push rod box 422 continues to retract, and the roller 44 moves along the X direction in the sliding groove 45, pushing the switch beam 20 to switch around the fixed support point 30.

[0155] In the locking stage: 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 buckles upward and contacts the first locking sensor 515, the push rod contact 410 of the push rod box 422 contacts the push rod travel switch 49, the push rod motor 41 stops running, the push rod box 422 stops retracting, and the locking is completed.

[0156] It can be understood that the specific process of the above-mentioned turnout unlocking-switching-locking stage reflects the linkage between the locking device 50 and the drive transmission assembly 40 to achieve turnout unlocking-switching-locking. Compared with the existing turnout that requires a separate driving device for the locking device 50, and both unlocking and locking must rely on the driving force of a separate driving device, the operating efficiency of the train in a long-term running railway system is improved.

[0157] The advantages of the present invention compared with the prior art can be shown in the following table:
