[0024] It can be seen from the analysis that compared with the prior art, the advantages and beneficial effects of the present invention are:

[0025] 1. The fixed turnout of the present invention adopts a passive fixed structure, does not contain electrical components, and does not need to perform actions during use. During operation, the railcar can pass smoothly according to the predetermined instructions, which can greatly improve the traffic efficiency, reduce the tracking interval of the railcar, avoid traffic jams, and have high safety.

[0026] 2. The guide plate of the present invention is connected to the top of the connecting plate at a certain angle, which can prevent the steering wheel from falling off during guidance and can also prevent potential safety hazards caused by failure. The auxiliary guide plate is located directly below the guide plate and can play a guiding role in the event of failure of the guide plate.

[0027] 3. The bifurcated component of the present invention can support the load-bearing running wheels when the rail vehicle turns, thereby making the rail vehicle turn smoothly and reducing bumps. The cover plate, the web plate, the pedal, and the bottom plate work together to form a box-shaped turnout structure, which can increase the service life of the fixed turnout and reduce the number of maintenance times during the service life.

[0028] 4. When the rail vehicle travel steering device of the present invention changes lanes at a fixed switch, it selects the required path according to the instructions of the signal system. There is no need to wait when passing, and point-to-point transportation is carried out entirely by the dispatch of the signal system, which can improve the traffic efficiency and truly achieve congestion-free switch intersections.

[0029] 5. The rail vehicle walking steering device of the present invention guides the rail vehicle to change lanes quickly and smoothly by rolling cooperation. The upper connecting arm and the lower connecting arm rotate synchronously, and the steering wheel on the upper rotating shaft contacts the guide plate while the steering wheel on the lower rotating shaft does not contact the auxiliary guide plate. When the guide plate deforms and fails, the steering wheel on the lower rotating shaft contacts the auxiliary guide plate for guidance, which can make the operation of the rail vehicle safer and more reliable.

[0038] Please refer to Figures 1 to 5 ,in, Figure 1 It is a structural schematic diagram of a fixed turnout of the present invention; Figure 2 The fixed turnout of the present invention and the steering device of the rail vehicle are shown in FIG. Figure 1 ; Figure 3 The fixed turnout of the present invention and the steering device of the rail vehicle are shown in FIG. Figure 2 ; Figure 4 It is a schematic diagram of the positional relationship of the bifurcating components of the fixed turnout of the present invention; Figure 5 It is a schematic structural diagram of the extrusion block of the fixed turnout of the present invention.

[0039] like Figure 1 and Figure 2As shown, the present invention provides a fixed turnout for changing the lanes of a rail vehicle, dividing the track into two or two into one on the driving path. The fixed turnout mainly includes pedals 13, which appear in pairs and extend in a Y-shape along the track direction, and are used to bear the gravity of the rail vehicle transmitted from the rail vehicle's travel steering device; webs 5, which appear in pairs and are uprightly connected to the outside of the paired pedals 13, extend in a Y-shape along the track direction, and are consistent with the extension direction of the pedals 13; guide parts, which appear in pairs and are installed above the pedals 13, extend in a Y-shape along the track direction, and the guide parts include connecting plates 7 and guide plates 9. The webs 5, connecting plates 7, and guide plates 9 form a U-shaped structure, which can guide the steering of the rail vehicle's travel steering device.

[0040] The three branches of the Y-shape of the fixed turnout of the present invention are each used to connect a track. After the three branches are connected to the three tracks, they become one with the three tracks and are Y-shaped when viewed from above. After being put into operation, it can not only realize the one-to-two split of the railcar at the fixed turnout (when the railcar enters the fixed turnout at the bottom of the Y-shape and chooses to change lanes, it can choose to change lanes to the upper left or to the upper right, thereby realizing one-to-two split), but also realize two-in-one (when the railcar enters the fixed turnout at the upper left or upper right of the Y-shape and chooses to change lanes, it can change lanes to travel to the bottom of the Y-shape, thereby realizing two-in-one). The two webs 5 of the present invention are arranged face to face, and the pedal 13 is connected to the bottom of the web 5, and an angle is set between the pedal 13 and the web 5. An angle is set between the connecting plate 7 and the web 5, and the connecting plate 7 is located above the pedal 13, one side of the connecting plate 7 is connected to the web 5, and the other side is connected to the guide plate 9, and the guide plate 9 is connected to the top of the connecting plate 7 at a certain angle. There is a gap between the two pedals 13 and between the two guide plates 9 for the rail vehicle to pass through.

[0041] The pedal 13 of the fixed turnout of the present invention is used to support the running wheel 11 of the rail vehicle when in use, and provide a track for the rolling of the running wheel 11; the web 5 is used to install the pedal 13, the connecting plate 7 and the guide plate 9, and support the guide wheel 15 of the rail vehicle, and provide a running track for the guide wheel 15. The two guide plates 9 gradually extend in opposite directions, and can provide guidance for the steering of the rail vehicle when they cooperate with the steering wheel 6 of the rail vehicle. When guiding with the steering wheel 6, the steering wheel 6 enters the approximately U-shaped groove surrounded by the web 5, the connecting plate 7, and the guide plate 9, and the circumferential surface of the steering wheel 6 contacts the guide plate 9 and rolls on the surface of the guide plate 9, thereby guiding the rail vehicle. The guide plate 9 is connected above the connecting plate 7 at a certain angle (for example, the angle between the guide plate 9 and the connecting plate 7 can be an acute angle, a right angle, or an obtuse angle), which can not only play a guiding role when guiding, but also play a certain accommodating role for the steering wheel 6 to prevent the steering wheel 6 from falling off during guidance. At the same time, it can also prevent potential safety hazards caused by failure (during guidance, the steering wheel 6 applies pressure to the guide plate 9. As the number of uses increases, the connecting plate 7 and the guide plate 9 will inevitably deform. When deformation occurs, the side of the connecting plate 7 connected to the guide plate 9 bends downward, and the guide plate 9 tilts to a certain extent in the opposite direction of the guidance as it bends. At this time, although the guide plate 9 fails to a certain extent, it can still ensure that the steering wheel 6 does not disengage, thereby avoiding the occurrence of safety accidents). The fixed turnout of the present invention adopts a passive fixed structure, does not contain electrical components, and does not need to perform actions during use. When in use, the rail vehicle passes smoothly according to the predetermined instructions, which can greatly improve the traffic efficiency, reduce the tracking interval of the rail vehicle, avoid traffic jams, and has high safety.

[0042] As a preferred embodiment of the present invention, the angle between the pedal 13 and the web 5 is 90°; the angle between the connecting plate 7 and the web 5 is 90°; the angle between the guide plate 9 and the connecting plate 7 is 90°, that is, the connecting plate 7 and the guide plate 9 can be integrated, for example, constructed with L-shaped steel to improve the connection strength. The vertical arrangement of the connecting plate 7 and the web 5 and the vertical arrangement of the guide plate 9 and the connecting plate 7 make the angle between the guide plate 9 and the pedal 13 90°, which can make the guide plate 9 withstand the vertical pressure during the guidance and avoid the generation of pressure in other directions. At the same time, as another measure to prevent potential failure, in the embodiment, a reinforcing plate 8 is provided at the bottom of the connecting plate 7. The reinforcing plate 8 is a triangular plate, and the two sides are respectively connected to the web 5 and the connecting plate 7, and the connection is welded (full welded) to improve the bending resistance of the connecting plate 7.

[0043] In order to further improve the safety when changing lanes, Figure 2As shown, in the present invention, auxiliary guide plates 14 are also included. The auxiliary guide plates 14 appear in pairs, are installed below the pedal 13, extend in a Y-shape along the track direction, and are used to assist in guiding the steering of the walking steering device. The auxiliary guide plate 14 is installed on the lower surface of the pedal 13, and an angle is set between the auxiliary guide plate 14 and the pedal 13. Specifically, there are two auxiliary guide plates 14, and one auxiliary guide plate 14 is installed on each of the two pedals 13. The auxiliary guide plate 14 is located below the guide plate 9. When the rail vehicle changes lanes, the auxiliary guide plate 14 serves as a safety supplement to the guide plate 9, and can cooperate with the steering wheel 6 for guidance when the guide plate 9 fails.

[0044] As a preferred solution, Figure 2 As shown, the angle between the auxiliary guide plate 14 and the pedal 13 is 90°, and the auxiliary guide plate 14 and the guide plate 9 are located in the same plane, that is, projected in a direction perpendicular to the pedal 13, the contours of the guide plate 9 and the auxiliary guide plate 14 coincide, which can ensure that the force direction is consistent and facilitates construction.

[0045] When the rail vehicle is running on the track (not running at the switch), it always runs along the track. When changing tracks (one-to-two or two-to-one) at the switch, one side of the running wheel 11 needs to leave the original track. In order to ensure smooth and safe operation at the moment of leaving, Figure 3 and Figure 4 As shown, the fixed turnout of the present invention is also provided with a bifurcation component, and the bifurcation component includes a V-shaped plate 16 and a bottom plate 18. The V-shaped plate 16 is located between the two webs 5, and together with the two webs 5, constitutes three branches of the fixed turnout. The bottom plate 18 is connected to the bottom of the V-shaped plate 16, is located between the two pedals 13, and is located in the same plane as the two pedals 13. There are gaps on both sides of the bottom plate 18 and the two pedals 13 for the rail vehicle to pass through. When the running wheel 11 is divided into two tracks, the running wheel 11 that has left the original track will immediately contact the bottom plate 18 after leaving the original track, and roll on the upper surface of the bottom plate 18; when the running wheel 11 is two-in-one track change, the running wheel 11 that has left the original track will contact the bottom plate 18 after leaving the original track, and immediately enter the pedal 13 after leaving the upper surface of the bottom plate 18 and roll, so that the rail vehicle can change lanes smoothly and reduce bumps.

[0046] In order to enhance the structural stability of the V-shaped plate 16 , the V-shaped plate 16 includes a circular tube and two plates. The two plates are arranged in a V shape and are respectively connected to the circular tube. The circular tube is located at the sharp corners of the V shape and is welded to the two plates, which can improve the structural strength of the V-shaped plate 16 .

[0047] When a railcar changes lanes at a fixed turnout, correct steering is the prerequisite for ensuring the safe operation of the railcar. When the track is split into two, the railcar will not derail regardless of whether the lane change is correct or not; when the track is merged into one, if the lane change is wrong, it may cause great losses. In order to reduce the possible losses caused by mistakes when the track is merged into one, such as Figure 4 and Figure 5 As shown, in the present invention, a squeeze block 21 is provided at the bottom of the bottom plate 18, and there are two squeeze blocks 21, which are symmetrically distributed on the bottom plate 18. The surface of the squeeze block 21 facing the auxiliary guide plate 14 is a slope surface, and the bottom of the Y-shaped fixed turnout is the slope bottom. Figure 5 As shown in the figure, the slope of the squeeze block 21 can bounce the steering wheel 6 back to the correct side (the side where the guide plate 9 on the track is located). Furthermore, even if the speed of the rail vehicle is too fast to allow the steering wheel 6 to rebound in time, the steering wheel 6 (the steering wheel 6 on the lower connecting arm 12) will be squeezed together with the squeeze block 21. At this time, the squeeze block 21 can provide a buffering effect to the rail vehicle, and the rail vehicle will not crash violently and stop, causing damage to the rail vehicle, or frightening passengers.

[0048] When a rail vehicle is in operation, it is necessary to consider not only factors such as operating efficiency and safety, but also service life and maintenance cycle. In order to extend the service life of fixed turnouts and reduce the number of maintenance times, such as Figure 1 , Figure 3 and Figure 4 As shown, in the present invention, it also includes a cover plate 1, the projection of the cover plate 1 perpendicular to the length direction is Y-shaped, and is respectively connected to the top of the V-shaped plate 16 and the top of the two webs 5. The cover plate 1, the web 5, the pedal 13, and the bottom plate 18 together form a box-shaped turnout structure, which can delay the rust of the pedal 13, the web 5, the bifurcation component, and the guide part, and avoid dust accumulation, thereby increasing the service life of the fixed turnout, reducing the number of maintenance times during the service life, and achieving a maintenance-free effect in a certain sense. At the same time, the introduction of the cover plate 1, in conjunction with the web 5, the connecting plate 7, and the guide plate 9, can form a shape with a rectangular cross-section and a small opening on one side at the guide plate 9, which can further prevent the steering wheel 6 from detaching during guidance.

[0049] Under the premise of ensuring operation efficiency and safety, operation stability is also an important factor to be considered. Figure 1 , Figure 2 and Figure 4As shown, in the present invention, one end of the guide plate 9 in the length direction is provided with an introduction section 19, and the other end is provided with an outlet section 20. The introduction section 19 and the outlet section 20 are both arc-shaped, bent away from the web where the guide plate 9 is located, and are tangentially connected to the guide plate 9 at the junction between the introduction section 19 and the outlet section 20, which is convenient for the connection and separation of the steering wheel 6 of the rail vehicle, and can play a buffering role in the process of the steering wheel 6 connecting to the guide plate 9, greatly reducing the impact and vibration caused by the rail vehicle turning. Further, one end of the auxiliary guide plate 14 in the length direction is provided with an auxiliary introduction section, and the other end is provided with an auxiliary outlet section. The auxiliary introduction section and the auxiliary outlet section are both arc-shaped, bent away from the web 5 where the auxiliary guide plate 14 is located, and are tangentially connected to the auxiliary guide plate 14 at the junction between the auxiliary introduction section and the auxiliary outlet section. The curvature radius of the introduction section 19 is smaller than the curvature radius of the auxiliary introduction section, and the curvature radius of the outlet section 20 is smaller than the curvature radius of the auxiliary outlet section, which is convenient for the introduction and export of the steering wheel 6.

[0050] In order to achieve smooth lane change, Figure 3 and Figure 4 As shown, the pedal 13 of the present invention is also provided with a ramp surface 17. Along the length direction of the pedal 13, the ramp surface 17 is located between the lead-in section 19 and the lead-out section 20. More specifically, the ramp surface 17 is located between the lead-in section 19 and the bifurcating component and is close to the bifurcating component. Each pedal 13 is provided with a ramp surface 17, and the two ramp surfaces 17 are symmetrically arranged with the ramp surfaces facing each other. The arrangement of the ramp surface 17 allows the running wheel 11 to have a gentle transition process when it is disengaged from the pedal 13 or connected to the pedal 13 during the change of direction, thereby achieving a smooth lane change.

[0051] Based on the fixed turnout, the present invention also provides a rail vehicle travel and steering device, which is used to connect the top of the rail vehicle to achieve the travel and steering of the rail vehicle. Figure 2 and Figure 3 As shown, the rail vehicle travel steering device includes a travel mechanism and a steering mechanism. The travel mechanism can roll in the track and transfer the gravity of the rail vehicle to the pedal 13 of the track. The steering mechanism is installed above the travel mechanism, and due to the action of the guide plate 9 in the turnout, the rail vehicle can change lanes at the turnout. Specifically, the steering mechanism cooperates with the guide plate 9, guides the rail vehicle to change lanes under the pulling force of the guide plate 9, and realizes the rapid and smooth lane change of the rail vehicle.

[0052] In the present invention, lane changing is achieved by cooperating with the rail vehicle travel steering device and the fixed turnout. When changing lanes, the rail vehicle travel steering device selects the required path according to the instructions of the signal system. There is no need to wait when passing, and point-to-point transportation is carried out entirely by relying on the dispatch of the signal system, which can greatly improve the traffic efficiency and truly achieve congestion-free turnouts.

[0053] As Figure 1 and Figure 2 shown, the traveling mechanism of the present invention includes a frame body 10 and traveling wheels 11. The traveling wheels 11 are rotatably installed on the frame body 10 and are in rolling cooperation with the pedal 13.

[0054] As Figure 1 and Figure 2 shown, the steering mechanism of the present invention includes an upper steering mechanism and a lower steering mechanism. Both the upper steering mechanism and the lower steering mechanism are installed on the mounting frame. The upper steering mechanism includes an upper connecting arm 3 and an upper rotating shaft 4. The lower steering mechanism includes a lower connecting arm 12 and a lower rotating shaft. The mounting frame is installed on the frame body 10 and is fixedly connected to the frame body 10. One end of the upper connecting arm 3 and one end of the lower connecting arm 12 are installed on the mounting frame and form a U-shaped structure with the mounting frame, and can rotate around the axis of the mounting frame 2. The other end of the upper connecting arm 3 is installed with an upper rotating shaft 4, and the other end of the lower connecting arm 12 is installed with a lower rotating shaft. A steering wheel 6 is installed on each of the upper rotating shaft and the lower rotating shaft. The steering wheel 6 is located inside the opening of the U-shaped structure. During steering, the upper connecting arm 3 and the lower connecting arm 12 execute the instructions of the signal system and rotate, and then the steering wheel 6 on the upper rotating shaft 4 enters the approximately U-shaped groove formed by the web 5, the connecting plate 7, and the guiding plate 9 and rolls on the inner side wall of the groove (the surface of the guiding plate 9 close to the connecting plate 7), thereby realizing the guiding function of the rail vehicle.

[0055] To ensure the reliability of operation, as Figure 2 shown, the distance between the axis of the lower rotating shaft and the axis of the mounting frame 2 is greater than the distance between the axis of the upper rotating shaft 4 and the axis of the mounting frame 2. The upper connecting arm 3 and the lower connecting arm 12 rotate synchronously during rotation, always remain parallel, and jointly form a U-shaped structure (the lower horizontal line of the U-shape is slightly longer than the upper horizontal line) that can rotate along the mounting frame 2 with the mounting frame 2. During steering, the upper connecting arm 3 and the lower connecting arm 12 execute the instructions of the signal system and rotate synchronously. The steering wheel 6 on the upper rotating shaft 4 contacts the guiding plate 9, and the steering wheel 6 on the lower rotating shaft does not contact the auxiliary guiding plate 14 and serves as a backup. When the guiding plate 9 fails, the steering wheel 6 on the lower rotating shaft starts to contact the auxiliary guiding plate 14 and serves as a guiding function, enabling the steering of the rail vehicle to be safer and more reliable.

[0056] To ensure the smoothness of operation, as Figure 2 and Figure 3As shown, the position design of the upper connecting arm 3 and the upper rotating shaft 4 is preferably such that: when turning, the contact line between the steering wheel 6 on the upper rotating shaft 4 and the guide plate 9, and the contact line between the running wheel 11 and the pedal 13, the projections of the two contact lines in the direction perpendicular to the upper surface of the pedal 13 overlap. The contact between the running wheel 11 and the pedal 13 is point contact, and the steering wheel 6 and the guide plate 9 are point contact. When the rail vehicle changes lanes (turns), the running wheel 11 and the steering wheel 6 rotate, and the running wheel 11 draws a line on the pedal 13, and the steering wheel 6 draws a line on the guide plate 9. At this time, it can be understood that the running wheel 11 is in line contact with the pedal 13, and the steering wheel 6 is in line contact with the guide plate 9. The projections of the two contact lines in the direction perpendicular to the pedal 13 overlap, which can make the rail vehicle turn smoothly and reduce the impact force on the steering wheel 6 and the guide plate 9.

[0057] The rail vehicle of the present invention can move only by rolling cooperation between the running wheel 11 and the pedal 13. In order to ensure that the running wheel 11 moves along a predetermined track, a groove that cooperates with the running wheel 11 can be provided on the pedal 13 to provide guidance for the running wheel 11. As another better implementation method, Figure 2 and Figure 3 As shown, the travel mechanism of the present invention further includes a guide wheel 15, which is rotatably connected to the frame 10 and rollingly cooperates with the web 5, so as to limit the travel track of the rail vehicle in both the horizontal and vertical directions to ensure travel safety.

[0058] Furthermore, in the present invention, the number of steering devices can be flexibly set, that is, one railcar can be provided with one railcar travel steering device, or multiple railcar travel steering devices can be provided. When the railcar is small in size and / or has a small load, so that the driving inertia is small and easy to turn, one railcar can be provided with one railcar travel steering device; when the railcar has a large driving inertia and is difficult to turn, one railcar can be provided with multiple railcar travel steering devices, and the multiple railcar travel steering devices are distributed side by side, and the multiple railcar travel steering devices use the same power source, which can guide the railcar in sections to ensure synchronization and consistency.

[0059] like Figures 1 to 5 As shown, the working process of the present invention is described as follows:

[0060] First, the one-in-two situation. When the rail car passes through a fixed turnout, the rail car selects a turning direction (left turn or right turn) to change lanes, and the steering wheel 6 extends into the side of the guide plate 9 corresponding to the turning direction, and presses against the inner wall of the guide plate 9 (a surface of the guide plate 9 facing the web 5 where the guide plate 9 is located). The steering wheel 6 rolls on the inner wall of the guide plate 9. As the guide plate 9 extends in the length direction, the guide plate 9 applies pressure to the steering wheel 6, and the direction of the pressure points to the direction of the lane change. After the pressure on the steering wheel 6 is transmitted to the frame 10 of the rail car, it is equivalent to the guide plate 9 applying a pulling force to the frame 10, so that the frame 10 can be pulled to change lanes along the guide of the guide plate 9, thereby realizing the lane change of the rail car.

[0061] Second, the two-in-one situation. When the rail vehicle passes through a fixed turnout, when the rail vehicle selects a turning direction to change lanes, if the turning direction is correct, the steering wheel 6 extends into the side of the guide plate 9 corresponding to the turning direction, and presses against the inner wall of the guide plate 9. The guide plate 9 applies a pulling force to the frame 10, thereby pulling the frame 10 along the guide of the guide plate 9 to change lanes, thereby realizing the lane change of the rail vehicle; if the turning direction is wrong, the steering wheel 6 on the lower shaft is bounced back to the correct side by the slope of the extrusion block 21, or the steering wheel 6 on the lower shaft is squeezed together with the extrusion block 21 to stop the rail vehicle.

[0062] In summary, the fixed turnout of the present invention is a completely fixed turnout, without an action actuator, no action judgment is required, and there is no problem of fatigue life of the action actuator. The rail vehicle travel steering device of the present invention is cleverly combined with the fixed turnout in the form of a mechanical structure, and at the same time, the particularity of the force mode of the rail vehicle (suspended train) is utilized. When turning, the fixed turnout only bears a very small lateral force, and has a long service life. The rail vehicle only bears a small amount of impact to achieve path selection. There is no need to stop when traveling in the road network, and it can run directly point-to-point quickly, which can greatly improve the operation efficiency. When the rail vehicle is running, the path can be selected in advance. Under the control of the signal system, the rail vehicle travel steering device is activated. When turning, the steering wheel 6 is automatically connected to the guide plate 9. Under the guidance of the guide plate 9, safe, stable, smooth and efficient steering can be achieved.

[0063] It is known from common technical knowledge that the present invention can be implemented by other embodiments that do not deviate from its spirit or essential features. Therefore, the above disclosed embodiments are only illustrative in all respects and are not exclusive. All changes within the scope of the present invention or within the scope equivalent to the present invention are included in the present invention.
