Description

Technical Field

[0001] This application relates to the field of passenger ground cable car technology, and in particular to a connecting passenger ground cable car system. Background Technology

[0002] For passenger comfort and safety, the floor of a passenger cable car should be level, and the inclination angle of the chassis (the angle between the floor and the chassis) should be the same as the slope of the track. However, ground tracks generally have varying slopes, which causes changes in the angle of the chassis. To adapt to these slope changes, existing technologies employ several solutions, but each has its own drawbacks, including: (1) The average of the maximum and minimum gradients of the line is used as the tilt angle of the chassis. This can keep the car floor level as much as possible in different line sections. The disadvantage of this scheme is that when the gradient of the line changes greatly, the change in the levelness of the car floor will exceed the range that passengers can accept, resulting in instability.

[0003] (2) For concave track sides, a track pressure wheel is used to ensure that the traction steel rope runs along the track and will not detach from the reliable support of the support wheel. The disadvantage of this scheme is that the track pressure wheel makes the traction device structure of the car more complex and reduces the traction force.

[0004] (3) A longitudinally swaying carriage is adopted, with the carriage body suspended on a horizontal axis, which can ensure the level of the carriage floor on different track gradients. The disadvantages of this scheme are: complex structure, high cost, and the risk of serious overturning when the shock absorption and damping devices of the carriage swaying fail.

[0005] (4) The partially curved floor can ensure that standing passengers can stand vertically by holding onto the railings at different slopes. The disadvantage of this solution is that it is inconvenient for passengers to walk in the carriage when the train stops, resulting in low efficiency for passengers getting on and off the train.

[0006] (5) The carriage is connected to the chassis by a hinge shaft and an adjustment mechanism with guide wheels to keep the carriage level under different track gradients. The disadvantage of this scheme is that steel structure rails must be used as guide rails for the adjustment structure, and it is generally only suitable for small cable cars.

Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0029] The following detailed description of some embodiments of the present invention is provided in conjunction with the accompanying drawings. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0030] like Figure 1 As shown, this application embodiment provides a first type of connecting passenger ground cable car system. It includes an upper station 1, an intermediate station 3, and a lower station 5. The upper station 1 and the intermediate station 3 are connected by an upper section track 2 forming a first angle with the horizontal plane, and the intermediate station 3 and the lower station 5 are connected by a lower section track 4 forming a second angle with the horizontal plane. The upper section carriages 6 run on the upper section track 8, and the lower section carriages 7 run on the lower section track 4. A connecting platform for passenger transfer is provided in the intermediate station 3 area. Furthermore, the first angle is greater than the second angle, meaning the slope of the upper section track 2 is greater than the slope of the lower section track 4.

[0031] The upper section track 2 and the lower section track 4 have a relatively spaced section in the area of ​​the intermediate station 3. A first guide wheel 301 and a second guide wheel 302 are provided at the lower end of the upper section track 2, and the first guide wheel 301 and the second guide wheel 302 are inclined at a first angle with the horizontal plane. A third guide wheel 304 and a fourth guide wheel 305 are provided at the upper end of the lower section track 4, and the third guide wheel 304 and the fourth guide wheel 305 are inclined at a second angle with the horizontal plane.

[0032] A drive unit 101 is installed at the upper station 1, and two sets of guide rollers 303 are installed at the intermediate station 3. One end of the traction steel rope 8 is connected to the end of the upper section car 6 facing the upper station 1; the other end of the traction steel rope 8 is wound out by the drive unit 101, and then extends along the upper section track 2 in a turning direction until it turns 180° around the first guide roller 301, and after changing the tilt angle by the guide roller 303, it enters the fourth guide roller 305, and after turning 180° again, it extends into the lower section track 4, and finally connects to the end of the lower section car 7 facing the intermediate station 3.

[0033] The drive unit 101 is a double-groove or multi-groove friction drive motor capable of rotating in both directions, and can drive the upper section carriage 6 and the lower section carriage 7 to move towards each other or away from each other via the traction steel 8.

[0034] A detour wheel 502 is installed at the lower end station 5. One end of the balance steel cable 9 is connected to the end of the lower section car 7 facing the lower end station 5, and the other end of the balance steel cable 9 extends downward along the lower section track 4 and enters the detour wheel 502. After the balance steel cable 9 is led out through the detour wheel 502, it extends upward along the lower section track 4 until it turns at a 180° wrap angle to bypass the third guide wheel 304. After changing the tilt angle through the middle guide cable pulley 303, it enters the second guide wheel 302. After turning at a 180° wrap angle, it extends into the upper section track 2 and finally connects to the end of the upper section car 6 facing the middle station 3.

[0035] The traction steel rope 8 and the balance steel rope 9 form a closed loop through anchoring devices installed on the chassis of the upper section car 6 and the lower section car 7. The traction steel rope 8 is the upper loop, and the balance steel rope 9 is the lower loop.

[0036] The balancing steel cable 9 can provide tension balancing force for the lower section car 7, especially when the second included angle of the lower section track 4 is small or the traction force of the drive device 101 is insufficient. The tension balancing force provided by the balancing steel cable 9 to the lower section car 7 can enable the lower section car 7 to have sufficient downward force.

[0037] If we define the upward movement of the upper section car 6 towards the upper station 1 as the positive direction, then the lower section car 7 simultaneously moves towards the lower station 5; conversely, in the reverse direction, both the upper section car 6 and the lower section car 7 simultaneously move from the stations at both ends towards the middle station 3. When the lower section car 7 is at the lower station 5, the upper section car 6 is at the upper station 1. Passengers waiting at the upper station 1 and lower station 5 enter the upper section carriage 6 and lower section carriage 7 respectively. After the carriage doors are closed and other safety conditions are met, the cable car system reverses direction, with both upper section carriage 6 and lower section carriage 7 heading towards the intermediate station 3 and eventually stopping there. At this point, the doors of upper section carriage 6 and lower section carriage 7 open, and passengers disembark and proceed to the opposite carriages via the platform of intermediate station 3. Then, the cable car system moves forward, with upper section carriage 6 and lower section carriage 7 heading towards the upper station 1 and lower station 5 respectively and eventually stopping there, allowing passengers to board and alight. This achieves the purpose of bidirectional, reciprocating operation between upper station 1 and lower station 5, connecting passengers via intermediate station 3.

[0038] The movement of the upper section car 6 and the lower section car 7 towards the intermediate station 3 mainly relies on the component of the upper section car 6's weight along the upper section track 2. Therefore, the first included angle is usually more than 10° larger than the second included angle, ensuring that the component of the upper section car 6's weight along the upper section track 2 is sufficiently greater than the component of the lower section car 7's weight along the lower section track 4. Additionally, counterweights can be added to the upper section car 6 to ensure the smooth movement of both the upper section car 6 and the lower section car 7 towards the intermediate station 3.

[0039] In a preferred embodiment, the upper station 1 is further provided with a guide support for guiding the traction steel rope 8 or a pressure wheel 102 for limiting movement.

[0040] The lower station 4 is equipped with a lower guide sheave 501 for guiding the balance steel rope 9.

[0041] like Figure 2 As shown, this embodiment presents another, simpler, connecting passenger ground cable car system. Compared to the first embodiment, in this embodiment, only the traction steel cable 8 is provided, while the balance steel cable 9 is eliminated. Therefore, the second guide wheel 302, the third guide wheel 304, and the detour wheel 502 are also eliminated.

[0042] This implementation method is suitable when the second included angle of the lower section track 4 is large or when the traction force of the drive device 101 is sufficient, which can further simplify the system structure and reduce costs.

[0043] This application divides the cable car line into two sections with different gradients, each containing one car. Through the coordinated operation of the two cars, the terrain adaptability of the passenger ground cable car is significantly improved without the need for special additional technologies. Furthermore, the system is simple in structure, low in cost, safe, and comfortable, and has a wider range of applications. The intermediate station section where the two sections overlap is relatively short, reducing the line construction cost compared to traditional double-track passenger ground cable cars that use double tracks throughout or long passing sections.

[0044] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Various modifications and variations can be made to the present invention by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
