[0002] Urban rail transit is a vehicle transportation system that uses track structures for load-bearing and guidance. It mainly includes subway systems, light rail systems, monorail systems, magnetic levitation systems and automatic guided rail systems. Turnouts are a common facility in urban rail transit. They enable locomotives and vehicles to transfer from one track to another, fully utilizing the line's capacity. They are mainly composed of sleepers, fixed rails, movable rails and forked rails.

[0003] Traditional monorail turnouts typically consist of a running rail and a deforming rail. The turn rail is installed on a guide rail, which is equipped with a switch mechanism that controls the horizontal movement of the turnout for directional adjustment.

[0026] In order to deepen the understanding of the present invention, the present invention will be further described in detail below with reference to the examples. The examples are only used to explain the present invention and do not constitute a limitation on the scope of protection of the present invention.

[0027] according to Figure 1 、 2 As shown in Figures 3 and 4, this embodiment proposes a translational type small-track spacing single-crossover single-track turnout, comprising a running rail 1 and a turnout 2 arranged in the running rail 1, a matching block 5 is provided at the lower end of the turnout 2, and the matching block 5 is connected to a driving device arranged on the outer side of the running rail 1; the running rail 1 is composed of two fixed rails, and the turnout 2 is composed of two movable rails, and a matching block 5 connected to the driving device is provided at the lower end of each movable rail.

[0028] It also includes two rectangular frame blocks 7 provided below the turnout 2, which are respectively placed on both sides of the matching block 5 and perpendicular to the turnout 2; the rectangular frame blocks 7 are paved below the turnout 2, and can be fixedly connected to the running rail 1, or fixed to the track ground through mounting parts. When fixing, it is necessary to ensure that the frame groove on the rectangular frame block 7 is at the same height as the matching block 5.

[0029] It also includes card plates 6 fixed on both sides of the matching block 5, the card plate 6 passes through the rectangular frame block 7 away from one end of the matching block 5 and slides with the rectangular frame block 7, and an air pusher 12 is provided on the side of the rectangular frame block 7 away from the card plate 6, and the pushing end of the air pusher 12 is connected to the card plate 6, and a spring plate 11 is provided at the connection between the card plate 6 and the air pusher 12 to serve as a limiter; when the driving device controls the switch 2 to move in the running track 1 and change tracks, the matching block 5 will be driven by the driving device to push one side of the switch 2 toward the inner side of the running track 1, and the card plates 6 on both sides of the matching block 5 will also move together, and the rectangular frame blocks 7 mounted on both ends of the card plate 6 limit the matching block 5 by cooperating with the card plate 6, thereby improving the stability of the matching block 5 during operation.

[0030] In addition, when the card plate 6 is in motion, it will also push the air pusher 12 provided in the rectangular frame block 7. The air pusher 12 can absorb the force generated by the card plate 6 and the matching block 5 during the movement through the compression of the gas to prevent the matching block 5 from vibrating, thereby further improving the stability of the turnout 2 during the change of direction.

[0031] It also includes a guide rail 8 installed on the upper end of the rectangular frame 7, a slider 9 is provided on the upper end of the guide rail 8, the slider 9 is fixed to the lower end of the switch 2 and slides with the guide rail 8, and an exhaust pipe is provided at the joint between the guide rail 8 and the slider 9, and the exhaust pipe is connected to the exhaust end of the air pusher 12. The guide rail 8 installed on the upper end of the rectangular frame 7 guides the switch 2 by cooperating with the slider 9, so that the switch 2 moves horizontally. When the train is moving, some dust will be blown into the guide rail 8 by the wind. When changing tracks, these dust particles will easily get stuck in the joint between the guide rail 8 and the slider 9, affecting the normal sliding of the slider 9, and then causing the switch 2 to become unstable when in motion, and the wear will also be more severe.

[0032] In this embodiment, when a track change is being performed, the mating block 5 connected to the lower end of the turnout 2 pushes the air pusher 12 disposed within the rectangular frame 7 via the clamping plate 6. The air pusher 12 then discharges the gas within it through the exhaust pipe, forming an air flow in front of the sliding path of the slider 9, blowing away dust within the guide rail 8 and preventing interference with the track change of the turnout 2. This dust cleaning mechanism operates only when the turnout 2 needs to change track, making it easy to operate and energy-efficient.

[0033] The drive device includes an adjusting screw 4 assembled between the two running rails 1. The adjusting screw 4 passes through two matching blocks 5 and is threadedly engaged with the two matching blocks 5. One end of the adjusting screw 4 is fixedly connected to the output end of the switch motor 3 located on the outside of the running rail 1. The drive device can also be called a switch machine. It is used to change the position of the switch, change the direction of the switch opening, and lock the switch point rail. It is an important signal infrastructure equipment that reflects the position of the switch. The switch motor 3 on the drive device is the power part, and the adjusting screw 4 is the control part. When the adjusting screw 4 rotates, the two matching blocks 5 sleeved on the rod of the adjusting screw 4 will move in the same direction along the rod of the adjusting screw 4, so as to drive the switch 2 between the two running rails 1 closer to the inside of the running rail 1, and the other switch 2 away from the running rail 1, so as to realize the track change of the train. The drive device can be replaced by other translation mechanisms.

[0034] See also Figure 5 The slider 9 includes an upper seat 92 and a lower seat 91. The upper seat 92 is placed on the upper end of the guide rail 8 and connected to the upper end of the guide rail 8. The lower seat 91 is placed on the lower end of the lower seat 91 and fixedly connected to the lower seat 91. The lower end of the lower seat 91 cooperates with the guide rail groove 81 opened at the upper end of the guide rail 8. An exhaust port 93 is provided at the connection between the lower seat 91 and the upper seat 92. Among them, the upper seat 92 plays a role in fixing the turnout 2 and supporting it at the same time. The lower seat 91 is arranged in the guide rail groove 81 and guides the upper seat 92 through the cooperation of the guide rail groove 81. The output port of the exhaust port 93 is tilted downward and corresponds to the guide rail groove 81.

[0035] See also Figure 6 The air push member 12 includes an air cylinder 20 fixed in the rectangular frame block 7. The air cylinder 20 is provided with a piston rod 23 on the side facing the card plate 6. One end of the piston rod 23 is fixedly connected to a push plate 121 provided in the rectangular frame block 7. The push plate 121 is placed on one side of the card plate 6 and connected to the card plate 6. The other end of the piston rod 23 passes through the air cylinder 20 and is fixedly connected to a piston 22 provided in the air cylinder 20. The air cylinder 20 is provided with a valve seat 21 at one end away from the piston rod 23.

[0036] The exhaust pipe assembly includes an air duct 13, one end of which is connected to the air cylinder 20 through the air valve seat 21. The other end of the air duct 13 passes through the air holes formed on both sides of the upper connecting seat 92 and is fixedly connected to the upper connecting seat 92. The air holes are connected to the exhaust port 93. When the turnout 2 changes track, when the matching block 5 drives the clamping plate 6 to slide within the rectangular frame block 7, the push plate 121, under the push of the clamping plate 6, pushes the piston rod 23. The piston rod 23 drives the piston 22 in the air cylinder 20 to move toward the air valve seat 21, and the air in the air cylinder 20 is discharged through the air valve seat 21. The discharged gas enters the air duct 13, then enters the air holes formed on both sides of the upper connecting seat 92 through the air duct 13, and is finally discharged through the exhaust port 93. When the lower connecting seat 91 slides within the guide rail groove 81, it first blows the lighter dust particles in the guide rail groove 81 out of the guide rail 8 along the guide rail groove 81.

[0037] The valve seat 21 includes a seat body, on which are disposed a one-way exhaust valve and a one-way intake valve. The one-way exhaust valve communicates with the air conduit 13 and the valve seat 21 through the seat body, while the one-way intake valve communicates with the valve seat 21 through the seat body. The valve seat 21 serves to guide the gas within the cylinder 20 in one direction. When the air pusher 12 is evacuating air, a negative pressure forms within the cylinder 20, allowing gas to enter the cylinder 20 through the one-way intake valve on the seat body. At this time, the one-way exhaust valve closes. During exhaust, the gas within the cylinder 20, under the action of pressure, flows out through the seat body. At this time, the one-way intake valve closes, the one-way exhaust valve opens, and gas enters the air conduit 13.

[0038] See also Figure 4 The spring plate 11 includes a limit plate 18 and a spring 19. The limit plates 18 are fixed on both sides of the air cylinder 20. A limit rod 16 is inserted into the center of the limit plate 18. One end of the limit rod 16 passes through the limit plate 18 and slides with the limit plate 18. The other end of the limit rod 16 is fixedly connected to the push plate 121. The spring 19 is sleeved outside the rod body of the limit rod 16. One end of the spring 19 is fixedly connected to the limit plate 18, and the other end of the spring 19 is fixedly connected to the push plate 121. The spring plate 11 has two functions. One is that when the card plate 6 slides in the rectangular frame 7, the limit plate 18 guides the card plate 6 by cooperating with the limit rod 16, so that the card plate 6 and the push plate 121 can maintain the horizontal propulsion of the piston rod 23 in the rectangular frame 7. Secondly, when the matching block 5 is driven by the driving device and the clamping plate 6 also moves in the opposite direction, the air valve seat 21 will move close to the clamping plate 6 under the push of the compressed spring 19 to reset the air pusher 12.

[0039] Since the card plate 6 slides back and forth along the inner sidewall of the rectangular frame block 7 when it moves within the rectangular frame block 7, the joint between the card plate 6 and the rectangular frame block 7 will be severely worn during long-term use. In this embodiment, the two opposing inner sidewalls of the rectangular frame block 7 and the card plate 6 are provided with grooves 15. The grooves 15 cooperate with a plurality of needle rollers 14 provided at the upper and lower ends of the card plate 6. Each needle roller 14 is rotatably connected to the upper and lower ends of the card plate 6 and is in contact with the groove walls of the grooves 15. When the card plate 6 moves within the rectangular frame block 7, the needle rollers 14 located at the upper and lower ends of the card plate 6 roll along the grooves 15 in the grooves 15, replacing sliding friction with rolling friction. This can effectively reduce friction loss at the joint between the card plate 6 and the rectangular frame block 7 and improve service life.

[0040] See also Figure 1 The adjusting screw 4 is provided with a sheath, which is arranged outside the rod of the adjusting screw 4 and is fixedly connected to the adjusting screw 4. The adjusting screw 4 is placed between the two matching blocks 5 to provide dust protection for the rod of the adjusting screw 4 located between the two matching blocks 5. It should be noted that a gap should be left between the two ends of the adjusting screw 4 and the matching blocks 5 to allow the matching blocks 5 to move, so as to ensure that the matching blocks 5 can push the turnout 2 to move. In addition, the lower end of the sheath can be connected to a support member set at the upper end of the ground, and the adjusting screw 4 is supported by the support member to improve the stability of the screw transmission structure.

[0041] See also Figure 3 , a reinforcing rib 10 is provided at the connection between the matching block 5 and the card plate 6, and the reinforcing rib 10 is fixed by welding the matching block 5 and the card plate 6. By welding the reinforcing rib 10 at the connection between the two, the structural strength of the connection part between the matching block 5 and the card plate 6 can be effectively improved.

[0042] This is a translational type small-line spacing single-crossing single-track turnout. On the basis of a traditional single-track turnout, a card plate 6 is provided on each side of a matching block 5 for promoting the movement of the turnout 2. The card plate 6 is away from the matching block 5 and cooperates with two rectangular frame blocks 7 paved under the turnout 2. The guide rail 8 and the slider 9 provided on the upper end of the rectangular frame block 7 are used to limit the turnout 2. The rectangular frame block 7 limits the matching block 5 by cooperating with the card plate 6. When the card plate 6 is in motion, the air pusher 12 in the rectangular frame block 7 will be started, and the gas generated will be introduced into the matching position of the guide rail 8 and the slider 9, blowing the dust in the guide rail 8 out of the guide rail 8, avoiding interference with the movement and track change of the turnout 2, thereby improving the safety of the operation. Since the dust cleaning structure only works when the turnout 2 needs to change track, it also has the characteristic of easy control.
