Description

Technical Field

[0001] This invention relates to the field of rail transit technology, specifically to a turnout with a core translational magnetic levitation turnout. Background Technology

[0002] Maglev turnouts are key track devices enabling rapid switching between two maglev train lines. The high-speed maglev train is driven by power coils installed on both sides of the track, while turnout sidings do not require power coils. When the maglev train travels on the turnout siding, its wheels slide on the track, reaching speeds of approximately 100 km / h. Currently, maglev turnouts can be mainly classified into four categories: integral flexible turnouts, articulated turnouts, replacement beam turnouts, and translational turnouts. Traditional translational maglev turnouts suffer from problems such as excessively large and heavy single-section turnout beams. This invention proposes a turnout core translational maglev turnout, reducing the difficulty and risk of transporting and installing maglev turnouts. Summary of the Invention

A fork core mounting seat is fixedly mounted on the top of the top trolley, and the fork core mounting seat is fixedly mounted to the bottom of the translational fork core. A trolley upper housing is movably mounted on both sides of the bottom of the top trolley via hinges and pins. A trolley lower housing is fixedly mounted on the bottom of the trolley upper housing. Wheel axles are rotatably mounted inside the trolley upper housing and the trolley lower housing. Wheel bodies are fixedly mounted on the outer side of the wheel axles.

[0007] Preferably, the locking device includes a locker and a locking base. The locker is located on the side of the locking base. A locking bracket is fixedly installed on the top of the locking base by a mounting plate and anchor bolts. Two symmetrically arranged locking rollers are movably installed on the inner wall of the locking bracket by a roller axle clamp. A proximity switch is fixedly installed on the surface of the locking bracket and on the side of the locking rollers.

[0008] Preferably, the locker includes a mounting top plate, which is fixedly installed at the bottom of the translation switch core. A push rod mounting seat is fixedly installed on one side of the bottom of the mounting top plate, and an electric push rod is fixedly installed on the side of the push rod mounting seat. A connecting block is fixedly installed at the output end of the electric push rod. The connecting block is movably connected to the middle section of the locking pin. A fixing ring is movably fitted on the outer side of the locking pin, and the fixing ring is fixedly installed to the mounting top plate through a support.

[0009] Preferably, the locking pin has mounting grooves on both sides, and a plate is slidably inserted into the opening of the mounting groove. One side of the plate has a concave surface, and a limiting plate is fixedly installed on the other side of the plate. A toothed plate is fixedly installed on the side of the limiting plate, and a groove is provided on the side of the limiting plate and on the side of the toothed plate. A toothed column meshes between the two toothed plates, and the toothed column is movably connected to the inner wall of the mounting groove by a shaft.

[0010] Preferably, the end face of the locking pin is slidably inserted with two push plates, and a pressure plate is fixedly installed on the side end of the push plate. The surface of the push plate is provided with a strip-shaped hole, and the inner wall of the strip-shaped hole is provided with a tooth groove that meshes with the tooth column. A partition is fixedly installed between the inner walls of the two push plates, and a tension spring is fixedly installed between the partition and the side wall of the mounting groove.

[0011] Preferably, the cross-section of the translation switch core is a "mountain" shaped structure, with the left side of the translation switch core corresponding to the fixed track on the curved side and the right side of the translation switch core corresponding to the fixed track on the straight side.

[0012] Preferably, the platform serves as the infrastructure for installing the turnout system and is pre-cast from concrete. Bolts corresponding to the fixed rails on the curved side and the fixed rails on the straight side are pre-embedded on the platform. The fixed rails on the curved side are cast from concrete, with clearance holes for the trolley assembly at the bottom of the rails and cable routing holes on the rail surface. The fixed rails are installed and fixed to the platform using anchor bolts. All turnout cables are arranged through the cable routing holes on the rail surface, and drag chains are installed at the bottom of the turnout core to protect the turnout cables.

[0013] Compared with the prior art, the beneficial effects of the present invention are as follows: the magnetic levitation turnout with a lateral shifting turnout is driven by a motor that drives a reducer to rotate, which in turn drives the wheel axle and wheel body to rotate, and then the wheel body rolls on the rail, and then the entire trolley assembly moves laterally; the trolley assembly consists of two layers, the upper trolley consists of two top trolleys and a connecting frame; the lower trolley consists of four upper trolley shells, a lower trolley shell and wheel bodies; the present application adopts a two-layer trolley structure design, which effectively distributes the overall weight of the trolley assembly and the lateral shifting turnout, and improves the movement safety and reliability of the lateral shifting turnout.

[0014] This magnetic levitation turnout with a sliding turnout core moves laterally via a trolley assembly. Then, an electric push rod drives a locking pin outward, inserting it into two locking rollers. A pressure plate at the end of the locking pin presses against a proximity switch, stopping the electric push rod. Simultaneously, the pressure plate, pressed against the proximity switch, causes the push plate to retract inward, while the tension spring is passively pulled open. The push plate then drives a toothed column to rotate clockwise via a toothed groove. This rotation drives the toothed plates to expand outward to both sides, pushing the insert plates outward from both sides of the locking pin. Finally, the insert plates engage with the outer walls of the locking rollers on both sides, thus locking the position of the locking pin. This also locks the trolley assembly and the sliding turnout core after their movement, significantly improving the safety of the magnetic levitation turnout system. Attached Figure Description

[0019] Please see Figure 1-2, the present invention provides a technical solution: a translation-type maglev turnout, including a platform 1. The platform 1 is the infrastructure for installing the turnout system and is pre-cast from concrete. On the left side of the top of the platform 1, a curve-side fixed track 2 is fixedly installed, and the curve-side fixed track 2 is formed by concrete casting. On the right side of the top of the platform 1, a straight-side fixed track 3 is fixedly installed. Bolts corresponding to the curve-side fixed track 2 and the straight-side fixed track 3 are pre-embedded on the platform 1; a translation turnout core 4 is arranged between the curve-side fixed track 2 and the straight-side fixed track 3. The cross-section of the translation turnout core 4 is a "mountain" - shaped structure. The left side of the translation turnout core 4 corresponds to the curve-side fixed track 2, and the right side of the translation turnout core 4 corresponds to the straight-side fixed track 3. A trolley assembly 5 is arranged at the bottom of the translation turnout core 4. A relief hole for the trolley assembly 5 is arranged at the bottom of the track, and a wire routing hole is arranged on the track surface. The fixed track is installed and fixed to the platform 1 through anchor bolts; all the cables of the turnout are arranged through the wire routing holes on the track surface, and a drag chain is arranged at the bottom of the turnout core to protect the turnout cables.

[0020] Please refer to Figure 1-2 , locking devices 6 are arranged at the moving positions at both ends of the translation turnout core 4. The two locking devices 6 are not on the same horizontal line, and their function is to lock the position of the trolley assembly 5; an electric control box 7 is arranged on the side of the straight-side fixed track 3, and controllers for devices such as motors, proximity switches, and electric push rods are installed inside it; connecting finger plates 8 corresponding to each other are fixedly installed at both ends of the curve-side fixed track 2, the straight-side fixed track 3, and the translation turnout core 4.

[0021] Please refer to Figure 3-4 , the trolley assembly 5 includes a connecting frame 501, and the outer shape of the connecting frame 501 is in the shape of a "king" character; top-layer trolleys 502 are fixedly installed on both sides of the connecting frame 501. The outer shape of the top-layer trolleys 502 is trapezoidal, and a turnout core mounting seat 503 is fixedly installed on the top of the top-layer trolleys 502. The turnout core mounting seat 503 is fixedly installed with the bottom of the translation turnout core 4.

[0022] Please refer to Figure 3-4 , on both sides of the bottom of the top-layer trolley 502, a trolley upper shell 506 is movably installed through a hinge seat 504 and a pin shaft 505. A trolley lower shell 507 is fixedly installed at the bottom of the trolley upper shell 506. A wheel shaft 508 is rotatably installed inside the trolley upper shell 506 and the trolley lower shell 507. A wheel body 509 is fixedly installed on the outer side of the wheel shaft 508.

A drive motor 513 is fixedly installed on the outer wall of the motor mounting base 512. The output shaft of the drive motor 513 is fixedly installed on the input shaft of the reducer 514. The output shaft of the reducer 514 is fixedly installed on one end of its corresponding wheel axle 508. The drive motor 513 drives the reducer 514 to run, and the reducer 514 drives the wheel axle 508 and wheel body 509 to rotate. The wheel body 509 will then roll on the rail 510, thus realizing the movement of the trolley assembly 5.

[0024] Please see Figure 5-6 The locking device 6 includes a locking device 600 and a locking seat 601. The locking seat 601 is made of concrete. The locking device 600 is located on the side of the locking seat 601. The top of the locking seat 601 is fixedly installed with a locking bracket 604 by a mounting plate 602 and an anchor bolt 603. Two symmetrically arranged locking rollers 606 are movably installed on the inner wall of the locking bracket 604 by a roller shaft clamping plate 605. A proximity switch 607 is fixedly installed on the surface of the locking bracket 604 and on the side of the locking rollers 606.

[0025] Please see Figure 5-6 The locking device 600 includes a mounting plate 608, which is fixedly installed at the bottom of the translation switch core 4. A push rod mounting seat 609 is fixedly installed on one side of the bottom of the mounting plate 608. An electric push rod 610 is fixedly installed on the side of the push rod mounting seat 609. A connecting block 611 is fixedly installed at the output end of the electric push rod 610. The connecting block 611 is movably connected to the middle section of the locking pin 612. A fixing ring 613 is movably fitted on the outer side of the locking pin 612. The fixing ring 613 is fixedly installed to the mounting plate 608 via a support 614. The electric push rod 610 can drive the locking pin 612 to slide in the fixing ring 613. The forward movement of the locking pin 612 will insert it between the two locking rollers 606.

[0026] Please see Figure 7-11 The locking pin 612 has mounting grooves 615 on both sides. A plate 616 is slidably inserted into the opening of the mounting groove 615. A concave surface 617 is provided on one side of the plate 616. A limiting plate 618 is fixedly installed on the other side of the plate 616. A toothed plate 619 is fixedly installed on the side of the limiting plate 618. A groove 620 is provided on the side of the limiting plate 618 and on the side of the toothed plate 619. A toothed column 621 meshes between the two toothed plates 619. The toothed column 621 is movably connected to the inner wall of the mounting groove 615 by a shaft.

[0027] Please see Figure 7-11Two push plates 622 are slidably inserted into the end face of the locking pin 612. A pressure plate 623 is fixedly installed on the side end of the push plate 622. A strip hole is opened on the surface of the push plate 622. A tooth groove 624 that meshes with the toothed column 621 is opened on the inner wall of the strip hole. A partition 625 is fixedly installed between the inner walls of the two push plates 622. A tension spring 626 is fixedly installed between the partition 625 and the side wall of the mounting groove 615.

[0028] Please see Figure 12 When switching from the main line to the siding, the trolley assembly 5 drives the translation switch core 4 to move. The lower housing 507 of the trolley assembly 5 presses against the proximity switch 511, indicating that the trolley assembly 5 has moved into place. After that, the trolley assembly 5 is stopped, and the locking device 6 drives the locking pin 612 to move. The locking pin 612 presses against the proximity switch 607, indicating that the locking pin 612 is in place. Then the siding can be used for train operation. Conversely, switching to the main line can be achieved.

[0029] In summary, this application uses a drive motor 513 to drive a reducer 514, which in turn drives the wheel axle 508 and wheel body 509 to rotate. The wheel body 509 then rolls on the rail 510, causing the entire trolley assembly 5 to move laterally. The trolley assembly 5 consists of two layers: the upper trolley consists of two top-level trolleys 502 and a connecting frame 501; the lower trolley consists of four upper trolley shells 506, lower trolley shells 507, and wheel bodies 509. This application adopts a two-layer trolley structure design, which effectively distributes the overall weight of the trolley assembly 5 and the translation switch core 4, improving the movement safety and reliability of the translation switch core 4.

[0030] After the trolley assembly 5 drives the translation switch core 4 to move laterally, the electric push rod 610 drives the locking pin 612 to move outward. The locking pin 612 will then insert into the two locking rollers 606. The pressure plate 623 at the end of the locking pin 612 will press against the second proximity switch 607. At this time, the electric push rod 610 will stop running. Simultaneously, after the pressure plate 623 presses against the second proximity switch 607, the push plate 622 will retract inward into the locking pin 612, while the tension spring 626 will be passively pulled open. The toothed column 621 is driven to rotate clockwise through the toothed groove 624. The rotation of the toothed column 621 will drive the toothed plates 619 at the front and rear to expand outward to both sides. The expansion of the toothed plates 619 will push the insert plate 616 to extend out from both sides of the locking pin 612. Finally, the insert plate 616 will be locked on the outer wall of the locking rollers 606 on both sides, thereby locking the position of the locking pin 612, locking the position of the trolley assembly 5 and the translation switch core 4 after the movement, and greatly improving the safety of the magnetic levitation switch system.

[0031] In one application of the embodiment, the turnout switching time is only 30 seconds (while the traditional turnout switching time is more than 50 seconds). Only the turnout core needs to be moved. The weight of the turnout can be reduced by 30% compared with the existing structure, and the turnout switching time and movement safety are greatly improved.
