Description

Technical Field

[0001] The invention relates to the technical field of rail sightseeing vehicle equipment, and in particular to a rail chain passenger transport trolley system. Background Art

[0002] In scenic spots, tourist transfers between points are generally carried out by sightseeing vehicles. In order to reduce operating costs, a cable car system can generally be used, which is particularly suitable for round-trip passenger transportation between the top of a mountain and the foot of a mountain. However, a cable car system generally requires the construction of multiple mounting frames and cables connecting the mounting frames, etc. For example, the application publication number CN113442952A is a start-stop cable car based on a double-wire cable, wherein both ends of the double-wire cable are provided with a cable transmission structure, and a plurality of cable cars are installed on the double-wire cable. The cable car is installed on the double-wire cable through an installation unit, and the installation unit includes two engaging blocks corresponding to the two cables one by one and a rotating wheel corresponding to the engaging blocks one by one, and the engaging blocks and the rotating wheel are installed at the top of the cable car; the engaging block is L-shaped, with the long side located above the cable and the short side located outside the cable, and the rotating wheel is rotatably located inside the cable, and the rotating wheel is connected to the first motor in transmission, and the first motor is installed at the top of the cable car, and a passenger boarding and disembarking platform is provided at the cable transmission structure. The clamping block and the rotating wheel can realize the cable car to be detached from the double-wire cable through the opening and closing module, so that after the cable car stops and the passengers are picked up and dropped off, the clamping block and the rotating wheel can install the cable car back to the double-wire cable through the opening and closing module so that the cable car moves with the double-wire cable. However, the cable car system is usually expensive. At the same time, since the cable car is suspended in the air during operation, there are still problems such as failures are difficult to repair and rescue cannot be carried out in time in case of danger. These problems still exist when the height difference between the top of the mountain and the foot of the mountain is low. Therefore, it is not cost-effective to operate the cable car system when the height difference is small, and it takes a long time to recover the construction cost. Summary of the invention

Detailed implementation mode

[0032] The technical solutions in the present invention will be further described below with reference to the accompanying drawings and embodiments.

[0033] In the description of the present invention, it should be understood that the terms "center", "longitudinal", "transverse", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential", etc. indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus should not be construed as a limitation to the present invention.

[0034] In an exemplary embodiment, such as Figures 1 - 9As shown in the figure, this embodiment provides an orbital chain passenger car system, which includes a first platform 1 arranged at a higher position and a second platform 2 arranged at a lower position, as well as an annular track arranged around between the first platform 1 and the second platform 2, and a plurality of cars 3 arranged on the annular track, and an orbital platform 4 arranged between the first platform 1 and the second platform 2. There is a smaller height difference between the first platform 1 and the second platform 2 compared to that between the mountaintop and the foot of the mountain in the cable car system, and at the same time, there is a relatively long distance. Therefore, the orbital platform 4 has a smaller inclination. The cars 3 are used to reciprocally transport tourists between the first platform 1 and the second platform 2 to improve the tour efficiency. The orbital platform 4 in this solution is directly built on the ground, and the cars 3 move on the annular track of the orbital platform 4 to realize the transfer of tourists. There is no need to build installation frames, cables, etc. Therefore, the construction cost can be reduced. At the same time, if a failure or accident occurs, maintenance and rescue can be carried out more timely, and the operating cost is correspondingly lower. The construction cost can be recovered faster, and it can well replace the cable car system and is more suitable for use in scenarios with a smaller height difference. At the same time, the cars 3 adopt an open structure and the running speed can be relatively low (equivalent to or lower than that of the cable car). Under the condition of ensuring safety, tourists can visit more conveniently during the movement;Furthermore, the annular track includes a first annular groove 5, a second annular groove 6, an upward track 7 and a downward track 8 disposed between the first annular groove 5 and the second annular groove 6. The first annular groove 5 and the second annular groove 6 are respectively disposed on a first platform 1 and a second platform 2. The upward track 7 and the downward track 8 are both disposed on a track platform 4, and the upward track 7 is located inside the track platform 4 (i.e., there is a groove on the track platform 4 for installing the upward track 7, and the upward track 7 is installed in the groove). The downward track 8 is located obliquely above the track platform 4, and both the upward track 7 and the downward track 8 are parallel to the track platform 4. An annular drive chain 9 for connecting all the trolleys 3 is disposed inside the annular track. The trolley 3 is further provided with a pair of wheels 10 located on both sides of the annular track and capable of rolling contact with the track platform 4. The two wheels 10 are located on the inner and outer sides of the annular track and are in smooth rolling contact with the track platform 4, the first platform 1 and the second platform 2. When the trolley 3 moves upward, the two wheels 10 are located at the rear of the lower position. The annular drive chain 9 drives the trolley 3 to move upward and the wheels 10 also roll upward. When moving downward, the two wheels 10 are located at the rear of the higher position. The annular drive chain 9 drives the trolley 3 to move downward and the wheels 10 also roll downward. In this solution, the downward track 8 is disposed above a track platform 4 higher than the upward track 7 (i.e., the aforementioned downward track 8 is located obliquely above the track platform 4, and the upward track 7 is located inside the track platform 4). In this way, when moving downward, the position of the two wheels 10 relative to the downward track 8 is lower, and the rear of the trolley 3 moves downward, so that the tourists can maintain a stable sitting posture as when moving upward. Since both the first platform 1 and the second platform 2 are horizontally disposed, in order to facilitate tourists to get on and off the trolley 3, a fence 11 and a ladder 12 extending to the outer edges of the first platform 1 and the second platform 2 are further disposed in the middle of the first platform 1 and the second platform 2. When the trolley 3 is on the first platform 1 and the second platform 2, tourists can smoothly enter and exit the fence 11 through the ladder 12, and then get on and off the trolley 3 through a notch 52 provided on the fence 11.;

[0035] Such as Figures 1 - 13As shown, in the present invention, a driving gear ring 14 and a driven gear ring 15 are respectively arranged in the first annular groove 5 and the second annular groove 6. Below the first platform 1, a driver 13 for driving the driving gear ring 14 to rotate self is also arranged. The annular driving chain 9 is arranged around between the driving gear ring 14 and the driven gear ring 15. Driven by the annular driving chain 9, the trolley 3 transitions from the second annular groove 6 of the second platform 2 at a lower position to the upward running track 7, then to the first annular groove 5 on the first platform 1 at a higher position, then to the downward running track 8, and finally to the second annular groove 6 for circular movement. Specifically, the driver 13 can be a connected driving motor 16 and a speed reducer 17. The speed reducer 17 is located at the center of the circle and is connected to the connecting frame 18. The connecting frame 18 is located inside the driving gear ring 14 and is connected to the driving gear ring 14, so as to make the driving gear ring 14 rotate self, drive the annular driving chain 9 to operate, and then drive the driven gear ring 15 to rotate through the annular driving chain 9 (a connecting frame 18 with self-rotation setting is also correspondingly arranged inside the driven gear ring 15). Particularly, the arranged fence 11 can be fixed on the connecting frame 18 to rotate together. The inner bottom surface of the fence 11 is closed, for tourists to stand on and is also provided with a handrail 51. During the rotation process, the speed is the same as that of the trolley 3, so as to facilitate tourists to get on and off the trolley 3 through the notch 52 (get off first and then get on). The escalator 12 is separated from the fence 11, and the escalator 12 is in a relatively fixed position (fixed on other installation carriers, such as the external platform for tourists to queue up), so that there will be no mutual interference and it is convenient for tourists to enter and exit the fence 11; furthermore, the annular driving chain 9 includes a plurality of first connecting segments 19 and a plurality of second connecting segments 20 that are connected at intervals. Installation columns 21 extending upward are respectively fixedly connected to two first connecting segments 19 adjacent to one of the second connecting segments 20. An installation beam 22 is fixedly connected between the upper ends of the two installation columns 21. A supporting column 23 extending upward is rotatably connected to the installation beam 22. The trolley 3 is fixedly connected to the upper end of the supporting column 23, so that the trolley 3 and the annular driving chain 9 are connected; more specifically, the driving gear ring 14 and the driven gear ring 15 are respectively provided with a number of first meshing teeth 24 and a number of second meshing teeth 25. Both the first meshing teeth 24 and the second meshing teeth 25 can mesh with the second connecting segment 20, and a single first connecting segment 19 can be received or withdrawn between two adjacent first meshing teeth 24 and between two second meshing teeth 25. When the driver 13 operates, the annular driving chain 9 can be made to operate.

[0036] As Figures 1 - 13As shown, in further detail, the first connecting section 19 includes a pair of first connecting plates 26 disposed opposite to each other left and right, and a mounting block 27 fixed between the two first connecting plates 26. The mounting column 21 is fixedly connected to the mounting block 27, and upper and lower rollers 28 are respectively connected to the opposite sides of the two first connecting plates 26. The upper running track 7 and the lower running track 8 respectively include a bottom plate 29 that rolls into contact with the upper and lower rollers 28, and a pair of top plates 30 respectively located above the two upper and lower rollers 28. There may be a small gap between the upper and lower rollers 28 and the top plates 30, so that vertical limit is provided above, and it can also ensure the smooth rolling of the upper and lower rollers 28, thereby assisting the wheels 10 to enable the trolley 3 to run smoothly driven by the annular drive chain 9. Further, the second connecting section 20 includes a pair of second connecting plates 31 disposed opposite to each other up and down. Left and right rollers 32 are respectively connected to the opposite sides of the two second connecting plates 31. The upper running track 7 and the lower running track 8 also respectively include side plates 33 fixedly connected to the top plates 30 and the bottom plate 29. The two left and right rollers 32 are located between the two side plates 33. The two side plates 33 are located on both sides of the bottom plate 29. The bottom plate 29, the two side plates 33 and the two top plates 30 enclose a square structure with an open top surface. The annular drive chain 9 moves within the square structure. The left and right rollers 32 are arranged within the square structure and there may be a small gap between the two sides and the two side plates 33 to enable the annular drive chain 9 to move smoothly, and at the same time, it is also limited left and right by the two side plates 33, so that the trolley 3 runs more smoothly. More specifically, the provided mounting column 21 extends upward above the square structure, so that the mounting beam 22 can also be located above the square structure. The supporting column 23 is mainly located above the square structure and then connected to the bottom of the trolley 3. At the same time, there is a large distance between the mounting column 21 and the two top plates 30, so that the trolley 3 can run smoothly driven by the annular drive chain 9.

[0037] As Figures 1 - 13As shown, furthermore, a support beam 34 is rotatably connected to one of the mounting columns 21. The support beam 34 extends in a direction away from the other mounting column 21, and a first cross beam 35 is fixedly connected to the end thereof. The middle section of the first cross beam 35 is connected to the support beam 34, and elastic buffers are rotatably connected to both ends respectively. And the two elastic buffers are respectively connected to the two wheels 10. The provided support beam 34 is also located above the square structure, avoiding interference between structures such as the support beam 34, the first cross beam 35, and the elastic buffers and the square structure; more specifically, a pair of first mounting arms 36 are fixedly connected to one end of the support column 23. The two first mounting arms 36 are clamped on both sides of the middle section of the mounting beam 22 and are rotatably connected to the mounting beam 22 through a first mounting shaft 37. The trolley 3 is fixedly connected with a first ejector rod 38. The first ejector rod 38 extends downward and is fixedly connected to the end of the support column 23 away from the first mounting arm 36. The first ejector rod 38 can also be connected to the mounting frame 39. The bottom (the bottom surface of the seat) of the trolley 3 is fixed on the mounting frame 39. In this way, the connection of the trolley 3 is realized, and the trolley 3 and the mounting beam 22 are rotatable. In this way, during operation, the trolley 3 can achieve a small angle change to enable it to maintain balance and ensure the safety of tourists; the trolley 3 is also fixedly connected with a U-shaped frame 40. The two wheels 10 are respectively connected to the outer sides of both ends of the U-shaped frame 40. Second cross beams 41 are respectively fixedly connected to the inner sides of both ends of the two U-shaped frames 40. The elastic buffer includes a second mounting arm 42 fixedly connected to one end of the second cross beam 41, and a telescopic rod 43 rotatably connected to the end of the second mounting arm 42 away from the second cross beam 41. The end of the telescopic rod 43 away from the second mounting arm 42 is rotatably connected to one of the second cross beams 41. In this way, the installation of the two wheels 10 and the two elastic buffers is realized through the U-shaped frame 40. During the movement of the trolley 3, the elastic buffer makes the trolley 3 keep balanced by telescopic cooperation with the support column 23. At the same time, it should be noted that the running speed of the trolley 3 in the present invention is relatively slow. With the cooperation of the provided wheels 10 and the elastic buffers, the trolley 3 can run smoothly driven by the annular drive chain 9, and at the same time, the seat of the trolley 3 is horizontally arranged. Tourists can safely realize the tour in the trolley 3 and realize the transfer between the first platform 1 and the second platform 2; similarly, the U-shaped frame 40 and the trolley 3 are also connected through a second ejector rod 56 similar to the first ejector rod 38.

[0038] As Figures 1 - 13As shown, in a more detailed solution, the first engaging teeth 24 and the second engaging teeth 25 are both provided with tooth bodies. The tooth bodies can be inserted into or withdrawn from between the two second connecting plates 31 provided. The two second connecting plates 31 are also fixedly connected with a second mounting shaft 45, and both ends of the second mounting shaft 45 extend outside the two second connecting plates 31. Two left and right rollers 32 are rotatably mounted on both ends of the second mounting shaft 45. At the same time, there is an opening 44 facing away from the driving tooth ring 14 or the driven tooth ring 15. This opening 44 provides an accommodating space for the second mounting shaft 45. When the tooth body engages with the second connecting section 20, the opening 44 allows the second mounting shaft 45 to be inserted, avoiding mutual interference. Similarly, a third mounting shaft 46 is fixedly connected between the two first connecting plates 26, and the third mounting shaft 46 penetrates through the first connecting plates 26 and the mounting block 27 therebetween. Two upper and lower rollers 28 are respectively rotatably mounted on both ends of the third mounting shaft 46.

[0039] As Figures 1 - 13 shown, more specifically, a connecting block 53 is also provided between the two first connecting plates 26 and the adjacent two second connecting plates 31. The left and right surfaces of the connecting block 53 are respectively fixedly provided with a fourth mounting shaft 54, and the upper and lower surfaces are respectively fixedly provided with a fifth mounting shaft 55. Both ends of the two first connecting plates 26 arranged oppositely left and right are respectively rotatably sleeved on the fourth mounting shafts 54 on both sides of the connecting block 53, and both ends of the two second connecting plates 31 arranged oppositely up and down are respectively rotatably sleeved on the fifth mounting shafts 55 on both upper and lower sides of the connecting block 53. In this way, the first connecting section 19 and the second connecting section 20 are connected to each other, that is, the overall structure of the annular drive chain 9 is formed. In particular, the tooth bodies (i.e., the first engaging teeth 24 and the second engaging teeth 25) can smoothly enter and exit between the adjacent two connecting blocks 53, so that the driving tooth ring 14 and the driven tooth ring 15 can smoothly engage with the annular drive chain 9.

[0040] As Figures 1 - 13 shown, in a further detailed solution, the telescopic rod 43 includes a telescopic column 47 fixedly connected to the second mounting arm 42, and a telescopic cylinder 48 slidably sleeved outside the telescopic column 47. One end of the telescopic column 47 can reciprocate within the telescopic cylinder 48. The telescopic cylinder 48 is fixedly connected with a connecting sleeve 49, and the connecting sleeve 49 is rotatably sleeved with the second cross beam 41. A buffer spring 50 sleeved outside the telescopic column 47 is also provided within the telescopic cylinder 48. During the movement of the trolley 3, the buffer spring 50 within the telescopic buffer member provides an elastic force to change the distance between both ends of the telescopic cylinder 48 and the telescopic column 47, ensuring that the trolley 3 is relatively horizontally arranged. In particular, a first abutting ring 57 is fixedly sleeved on the telescopic column 47, and a second abutting ring 58 is fixedly sleeved on the telescopic cylinder 48. During the telescopic process, the first abutting ring 57 and the second abutting ring 58 can abut against or separate from each other to prevent the telescopic column 47 from extending excessively into the telescopic cylinder 48.

[0041] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit them. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the purpose and scope of the technical solutions of the present invention, and they should all be covered within the scope of the claims of the present invention.
