Description

Technical Field

[0001] This utility model relates to the field of single-track sightseeing train technology, and in particular to a single-track sightseeing train turning turntable and auxiliary facilities. Background Technology

[0002] Currently, an increasing number of mountain tourist areas are constructing sightseeing rail lines. However, factors such as terrain, vegetation protection, and investment limit the development of loop and double-track lines. Consequently, single-track lines have emerged, often constrained by terrain at both ends to accommodate conventional 180-degree U-turns (such as...). Figure 1 This prevents the train from turning around, forcing the train to move forward or backward along the track. When reversing, the locomotive can only push the carriages backward, resulting in a poor driving experience for both the driver and the passengers.

[0003] Therefore, in mountainous scenic areas, the inability to turn trains around due to terrain limitations at both ends of the line becomes a problem that needs to be solved. Utility Model Content

[0004] Therefore, one objective of this utility model is to propose a turntable and auxiliary facilities for a single-track sightseeing train to solve the problems mentioned in the background art and overcome the shortcomings of the existing technology.

[0005] To achieve the above objectives, this utility model provides a turntable for turning around a single-track sightseeing train, including a turntable support, a track support, a turntable track, a central shaft component, a drive gear, and a driven pin gear;

[0006] The turntable track is laid on the foundation. A central shaft component is installed at the center of the turntable track. The central shaft component is concentrically connected to the center of the driven pin gear. The drive gear meshes with the driven pin gear and drives the driven pin gear to rotate. The driven pin gear is connected to the turntable bracket. A turntable wheel set is provided at the bottom of the turntable bracket where it intersects with the turntable track. The track bracket is fixed on the turntable bracket and has a straight toothed rail.

[0007] Preferably, the central shaft component includes a ball-shaped shaft and a split bushing. The ball-shaped shaft is fixedly embedded in the center of the foundation, and the split bushing is fixedly installed in the center of the turntable support. The ball-shaped shaft and the split bushing together form a self-aligning spherical bearing to ensure smooth rotation of the turning turntable.

[0008] In any of the above embodiments, it is preferred that the driven pin gear includes a first disk, a second disk, and a plurality of pins. The first disk and the second disk are respectively mounted on a split bushing. The first disk is located above the second disk. The first disk, the second disk, and the plurality of pins form an integral pin-type gear disk. The turntable bracket is fixed on the first disk.

[0009] In any of the above embodiments, it is preferred that the turntable support includes a first support rod and a second support rod, with the first support rod and the second support rod arranged parallel to each other on the first disc.

[0010] In any of the above embodiments, it is preferred that the turntable support further includes a third support rod, a fourth support rod, a fifth support rod, and a sixth support rod, wherein the third support rod is perpendicularly disposed at one end of the first support rod, the fourth support rod is perpendicularly disposed at the other end of the first support rod, the fifth support rod is perpendicularly disposed at one end of the second support rod, and the sixth support rod is perpendicularly disposed at the other end of the second support rod.

[0011] This utility model also provides an auxiliary facility, including a turnout, a platform track, and a locomotive departure track. The auxiliary facility is adapted to the aforementioned single-track sightseeing train turnaround turntable. One end of the platform track is connected to the inlet of the turnaround turntable, and the other end of the platform track is connected to the turnout. One end of the locomotive departure track is connected to the turnaround turntable, and the other end of the locomotive departure track is connected to the turnout.

[0012] Preferably, the turnout includes a straight rail, a curved rail, and a slide block. The straight rail and the curved rail are located on the slide block respectively, and the straight rail and the curved rail are on the same horizontal plane. The other end of the platform rail is connected to the curved rail, and the other end of the train headway rail is connected to the straight rail.

[0013] Compared with the prior art, the advantages and beneficial effects of this utility model are as follows:

[0014] This invention utilizes a relatively small diameter turning turntable. The turning turntable is driven by a motor, which in turn drives a meshing drive gear and a driven pin gear installed at the center of the turning turntable. This allows the sightseeing train to turn 180 degrees over narrow terrain.

[0015] Compared to conventional curve-type U-turn schemes, this method can save 50% on roadbed width. It makes it possible for trains to turn around when the line terminates in narrow terrain, thus solving the bottleneck problem in the planning of mountain scenic rail sightseeing train routes.

[0016] Additional aspects and advantages of this invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

Detailed Implementation

[0031] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0032] like Figure 2 As shown in the figure, a single-track sightseeing train turning turntable according to an embodiment of the present utility model includes a turntable bracket, a track bracket 1, a turntable track 2, a central shaft component, a drive gear 3, and a driven pin shaft gear 4.

[0033] The turntable track 2 is laid on the foundation. A central shaft component is installed at the center of the turntable track 2. The central shaft component is concentrically connected to the center of the driven pin gear 4. The drive gear 3 meshes with the driven pin gear 4 and drives the driven pin gear 4 to rotate. The driven pin gear 4 is connected to the turntable bracket. A turntable wheel set 26 is provided at the bottom of the turntable bracket where it intersects with the turntable track 2. The track bracket 1 is fixed on the turntable bracket. A straight track toothed rail 5 is provided on the track bracket 1.

[0034] The turning turntable is set on a circular foundation. The train head enters the straight track toothed rail 5. The drive gear 3 is installed on one side of the driven pin gear 4 to drive the driven pin gear 4 to rotate. The center line of the track support 1 is fixed on the turntable support along one diameter of the turntable track 2. The straight track toothed rail 5 is provided parallel to the track support 1. By setting the turning turntable, the sightseeing train head can be turned around in narrow terrain.

[0035] Furthermore, such as Figure 3 As shown, the central shaft component includes a spherical shaft 6 and a split bushing 7. The spherical shaft 6 is fixedly embedded in the center of the circular foundation, and the split bushing 7 is fixedly installed in the center of the turntable support. The spherical shaft 6 and the split bushing 7 together form a self-aligning spherical bearing to ensure the rotation of the turning table. This self-aligning spherical bearing has a certain degree of freedom to swing around the center of the sphere, which can ensure the smooth rotation of the turning table.

[0036] Specifically, such as Figure 4 , Figure 5 As shown, the driven pin-shaft gear 4 includes a first disc 8, a second disc 9, and several pins 10. The first disc 8 and the second disc 9 are respectively mounted on a split bushing 7. The first disc 8 is located above the second disc 9. The first disc 8, the second disc 9, and the several pins 10 form an integral pin-shaft type gear disc. The turntable bracket is fixed on the first disc 8. The several pins 10 are evenly distributed on the outer edges of the first disc 8 and the second disc 9, forming an integral pin-shaft type gear disc. This type of gear is easy to process, inexpensive, and suitable for low-speed, heavy-load applications.

[0037] Specifically, such as Figure 6 As shown, the turntable support includes a first support rod 11 and a second support rod 12, which are arranged parallel to each other on the first disc 8. The turntable support also includes a third support rod 13, a fourth support rod 14, a fifth support rod 15, and a sixth support rod 16. The third support rod 13 is perpendicular to one end of the first support rod 11, the fourth support rod 14 is perpendicular to the other end of the first support rod 11, the fifth support rod 15 is perpendicular to one end of the second support rod 12, and the sixth support rod 16 is perpendicular to the other end of the second support rod 12.

[0038] Four turntable wheels 26 are respectively installed at the junctions of the first support rod 11, the second support rod 12 and the turntable track 2. Four turntable wheels 26 are also installed between the third support rod 13, the fourth support rod 14, the fifth support rod 15, the sixth support rod 16 and the turntable track 2. To ensure the stability of the third support rod 13, the fourth support rod 14 and the first support rod 11, a first reinforcing rod 22 and a second reinforcing rod 23 are respectively installed between the third support rod 13 and the first support rod 11, and between the fourth support rod 14 and the first support rod 11. To ensure the stability of the fifth support rod 15, the sixth support rod 16 and the second support rod 12, a third reinforcing rod 24 and a fourth reinforcing rod 25 are respectively installed between the fifth support rod 15 and the second support rod 12, and between the sixth support rod 16 and the second support rod 12. The turntable support can rotate on the turntable track 2 via the turntable wheels 26.

[0039] Furthermore, such as Figures 7 to 9 As shown, this utility model also provides an auxiliary facility, including a turnout, a platform track 17, and a locomotive departure track 18. The auxiliary facility is adapted to the turntable of a single-track sightseeing train. One end of the platform track 17 is connected to the inlet of the turntable, and the other end of the platform track 17 is connected to the turnout. One end of the locomotive departure track 18 is connected to the turntable, and the other end of the locomotive departure track 18 is connected to the turnout.

[0040] Specifically, the turnout includes a straight rail 20, a curved rail 19, and a slide block 21. The straight rail 20 and the curved rail 19 are located on the slide block 21, and the straight rail 20 and the curved rail 19 are on the same horizontal plane. The other end of the platform rail 17 is connected to the curved rail 19, and the other end of the train headway rail 18 is connected to the straight rail 20.

[0041] The working principle of this utility model is as follows: A single-track sightseeing train turning turntable and auxiliary facilities are disclosed.

[0042] This utility model comprises a turning turntable, platform rails 17, train headway rails 18, and turnouts, forming a coordinated system. The main working component is the turning turntable, supplemented by platform rails 17, train headway rails 18, and turnouts as auxiliary facilities. The turning turntable is driven by a motor that powers a meshing drive gear 3 and a driven pin shaft gear 4 mounted at the center of the turntable. The start and stop of the turning turntable are controlled by position switches. The switch's state switching is achieved by applying external force through an actuating rod.

[0043] like Figure 10 As shown, the train enters the platform and stops via the switch. At this time, the switch is in the state where the curved rail 19 moves under the action of a controllable external force via the slide 21 and connects with the platform rail 17. At this time, the inlet of the turntable rotates to the position where it connects with the platform rail 17, waiting for the train to enter.

[0044] like Figure 11 As shown, the locomotive detaches from the carriage 28 and enters the turnout independently. At this time, the switch is in the state where the straight rail 20 moves under the action of a controllable external force through the slide 21 and connects with the locomotive exit rail 18, waiting for the locomotive to leave the platform.

[0045] like Figure 12 As shown, the locomotive completes the turn, and the exit of the turnout connects to the locomotive's exit track 18. At this time, the switch is in the curved track 19 state. Under the action of a controllable external force, the slide 21 moves and restores the connection with the platform track 17. Then the locomotive reverses, returns to the platform through the switch, hooks up with the waiting carriage 28, and drives out of the platform.

[0046] Through the above process, the locomotive completes a U-turn and changes direction. At the same time, carriage 28, waiting at the platform, also completes the process of dropping off and boarding passengers during the same period.

[0047] Compared with existing technologies, this invention has the following advantages: The width requirement for the roadbed is much lower, only half that of conventional methods. The rotation drive of the turntable in this invention is achieved through a driven pin gear 4 fixedly connected to its bottom near the shaft center and concentric with the rotation center. The driven gear is a pin gear structure, which is easy to manufacture, inexpensive, and suitable for low-speed, heavy-load applications.

[0048] It will be readily understood by those skilled in the art that this utility model includes any combination of the utility model content and specific embodiments described in the foregoing specification, as well as the various parts shown in the accompanying drawings. Due to space limitations and for the sake of brevity, not all of these combinations have been described in detail.
