This application is a national phase entry under 35 U.S.C. § 371 of International Application No. PCT/CN2017/075166, filed on Feb. 28, 2017, which claims priority to Chinese Patent Application No. 201610839154.9, filed on Sep. 21, 2016, content of all of which is incorporated herein by reference in its entirety.
The present disclosure relates to the field of transport technologies and, specifically, to a rail transport system.
A rail transport system such as a straddle-type monorail train has a complex structure, relatively high costs, relatively large occupied space, and a hidden danger in stability.
To facilitate evacuation of passengers in an emergency, the straddle-type monorail train in the related art is provided with an independent escape passage. Specifically, by additionally providing a frame on a rail, the frame is usually connected to a side of the rail and protrudes outward, and then a floor is laid on the frame to form a passage for evacuating passengers.
The inventors of this application have found through a large quantity of researches and experiments that disadvantages such as high costs, large occupied space, and a hidden danger in stability existing in the straddle-type monorail train provided with an escape passage in the related art are just caused by the structure of the foregoing escape passage. Specific reasons are as follows:
Since the frame and the floor laid on the frame are both additional structures independent of the rail, and a specific location of a rail vehicle in an emergency during travelling is unpredictable, the escape passage of this structure needs to be additionally disposed in the entire length direction of the rail (except a platform). The amount of work is enormous, which greatly increases the costs. Moreover, the frame and the floor are located at the side of the rail, which is equivalent to an extra portion extending in the width direction of the rail, which takes up a lot of space. In addition, the frame and the floor have a certain weight. Regardless of whether the rail vehicle is in an emergency, the frame and the floor are both erected on the rail, that is, even if the rail vehicle is travelling normally, the rail still needs to bear the weight of the frame and the floor, thereby increasing the weight borne by the rail, which has an adverse effect on the stability of the rail.

The following describes embodiments of the disclosure in detail. Examples of the embodiments are shown in the accompanying drawings. The same or similar elements and the elements having same or similar functions are denoted by like reference numerals throughout the descriptions. The embodiments described below with reference to the accompanying drawings are exemplary, aim to explain the disclosure, but cannot be understood as a limitation on the disclosure.
The present disclosure provides a rail transport system 1 has advantages such as facilitation of evacuation of passengers in an emergency, low costs, small occupied space, small rail weight bearing, and high stability.
The rail transport system 1 according to an embodiment of the present disclosure is described below with reference to accompanying drawings.
As shown in
A first recess as an escape passage 11 is constructed on the rail 10. The rail vehicle 20 includes bogies 21 and a vehicle body 22, the bogie 21 has a second recess 110 suitable for straddling the rail, the bogie 21 movably straddles the rail 10, and the vehicle body 22 is connected to the bogie 21 and pulled by the bogie 21 to travel along the rail 10. The second recess 110 is a straddle recess. Specifically, in a left and right direction, a minimum distance between two ends of the second recess 110 is greater than or equal to a minimum width of the rail.
As shown in
Optionally, a number of the compartments 23 is an odd number (for example, 3, 5, or 7). It may be understood herein that, the vehicle body 22 includes the plurality of compartments 23, and therefore the number of compartments 23 does not include 1. The plurality of compartments 23 is sorted sequentially along the length direction of the rail 10. For example, from the vehicle head to the vehicle tail, sequence numbers of the plurality of compartments 23 are sequentially 1, 2, 3, 4, 5, and the like, where for compartments 23 whose sequence numbers are odd numbers (for example, compartments 23 whose sequence numbers are 1, 3, 5, and the like), the bottom of each compartment 23 is connected to a bogie 21; and for compartments 23 whose sequence numbers are even numbers (for example, compartments 23 whose sequence numbers are 2, 4, and the like), the bottom of each compartment 23 is provided with no bogie 21.
Alternatively, the number of compartments 23 is an odd number or an even number. Among the plurality of compartments 23, the bottom of each of remaining compartments 23 other than a compartment 23 whose sequence number is 2 (for example, compartments whose sequence numbers are 1, 3, 4, 5, and the like) is connected to a bogie 21, and the bottom of only the compartment 23 whose sequence number is 2 is provided with no bogie 21.
Alternatively, the number of compartments 23 is a multiple of 3 and is greater than or equal to 6. Specifically, the number of compartments 23 is an even number greater than or equal to 6, and the plurality of compartments 23 of the vehicle body 22 are all used to form a plurality of compartment groups. In other words, the vehicle body 22 is formed by the plurality of compartment groups, and does not include a compartment 23 independent of the compartment groups, and neighboring compartment groups are hinged directly and are not spaced apart by an additional compartment 23. For example, the bottom of each of compartments 23 whose sequence numbers are 1, 3, 4, 6, 7, 9, and the like is connected to a bogie 21, and the bottom of none of compartments 23 whose sequence numbers 2, 5, 8, and the like is provided with a bogie 21.
It may be understood that, the bottom of a single compartment 23 may be provided with one or more bogies 21.
It can be understood that, that the rail 10 is provided with the escape passage 11 means that, the escape passage 11 is disposed on the rail 10 but not disposed on another additional component on the rail 10. To be specific, compared with the structure of the escape passage in the related art, in the rail transport system 1 according to this embodiment of the present disclosure, the rail 10 does not need to be provided with other components such as a frame and a floor, and the escape passage 11 is formed on the rail 10.
In the rail transport system 1 according to this embodiment of the present disclosure, the escape passage 11 is disposed on the rail 10, and when an emergency occurs, passengers can be evacuated in time by using the escape passage 11. Moreover, because the escape passage 11 is disposed on the rail 10 itself, no other additional structure needs to be added to the rail 10, and only the escape passage 11 needs to be disposed on the rail 10 itself along the length direction of the rail 10. Therefore, the amount of work of the rail transport system 1 may be greatly reduced. On one hand, costs are reduced, and on the other hand, occupied space is reduced. Moreover, the weight borne by the rail 10 does not need to be increased, which is favorable to stability of the rail 10. Therefore, the rail transport system 1 according to this embodiment of the present disclosure has advantages such as facilitation of evacuation of passengers in an emergency, low costs, small occupied space, small rail weight bearing, and high stability.
Moreover, the vehicle body 22 includes at least one compartment group. For three compartments 23 of one compartment group, only compartments 23 at two ends of the compartment group are provided with bogies 21, and an intermediate compartment 23 of compartment group is provided with no bogie 21. In other words, in the entire vehicle body 22, the bottom of at least one compartment 23 is provided with no bogie 21, and such a bogie arrangement manner can reduce a number of the bogies 21, thereby reducing the total weight of the rail vehicle 20, and reducing the costs and the height of the rail vehicle 20, and can reduce the bend radius, thereby improving a topographical adaptation capability of the rail vehicle 20. Moreover, based on this, the bottom of each of compartments 23 on two sides of and adjacent to a compartment 23 provided with no bogie 21 is provided with a bogie 21, thereby ensuring balance and stability of the vehicle body 22.
The rail transport system 1 according to a specific embodiment of the present disclosure is described below with reference to accompanying drawings.
As shown in
In an embodiment of the present disclosure, as shown in
Further, neighboring compartments 23 are further flexibly connected. For example, two neighboring compartments 23 are hinged at a lower portion of opposite end surfaces of the two compartments 23 and flexibly connected at an upper portion of the opposite end surfaces of the two compartments 23. In this way, the connection strength between the compartments 23 can be improved, thereby improving the entire structural strength of the vehicle body 22, and stress concentration can be avoided, to prevent the neighboring compartments 23 from being separated from each other.
In some embodiments of the present disclosure, as shown in
Specifically, the first end 31 of the escape door 24 is disposed adjacent to the vehicle bottom, and the second end 32 of the escape door 24 is disposed adjacent to the vehicle top when the escape door 24 is closed. In other words, when the escape door 24 is closed, the second end 32 of the escape door 24 is located above the first end 31 of the escape door 24; and when the escape door 24 is opened, the second end 32 of the escape door 24 is located below the first end 31 of the escape door 24. Therefore, the escape door 24 is converted from a closed state to an opened state through downward flipping. A flipping-type structure is used for the escape door 24, and a passenger in the vehicle can quickly open the escape door 24 in need of only a simple operation, to effectively improve escape efficiency.
Further, an inner surface of the escape door 24 is provided with a slide rail to help a passenger slide on the slide rail to the escape passage 11. It may be understood herein that, the inner surface of the escape door 24 is a surface facing the inside of the vehicle when the escape door 24 is closed.
In some other embodiments of the present disclosure, as shown in
Further, in the length direction of the rail 10, each of two end surfaces of two compartments 23 located at two ends of the vehicle body 22 is provided with an escape door 24, and the end surface is a surface of a current compartment away from an adjacent compartment. In an emergency, the escape doors 24 are simultaneously opened at the two ends of the vehicle body 22, and a wide air convection passage can be formed, so that toxic gases such as smog in the vehicle body 22 can be quickly dissipated. Moreover, a flipping-type structure is used for the escape door 24, and the passenger in the vehicle can quickly open the escape door 24 in need of only a simple operation, to effectively improve escape efficiency.
Specifically, The escape door 24 has a first end 31 and a second end 32, and the second end 32 of the escape door 24 is pivotably mounted onto the corresponding compartment 23, where the second end 32 of the escape door 24 is disposed adjacent to the vehicle top, and the first end 31 of the escape door 24 is disposed adjacent to the vehicle bottom when the escape door 24 is closed. In other words, when the escape door 24 is closed, the first end 31 of the escape door 24 is located below the second end 32 of the escape door 24; and when the escape door 24 is opened, the first end 31 of the escape door 24 may be located below the second end 32 of the escape door 24, or may be located above the second end 32 of the escape door 24. Therefore, the escape door 24 is converted from a closed state to an opened state through upward flipping. A flipping-type structure is used for the escape door 24, and the passenger in the vehicle can quickly open the escape door 24 in need of only a simple operation, to effectively improve escape efficiency, and facilitate collaboration between the escape door 24 and the escape cover plate 26.
Optionally, collaboration between the escape cover plate 26 and the escape door 24, may be dominated by the escape door 24, or may be dominated by the escape cover plate 26. Specifically, when passengers need to be evacuated, the escape door 24 may be actively opened, and the escape door 24 drives the escape cover plate 26 to open the escape port 25; or the escape cover plate 26 may be actively opened, and the escape cover plate 26 drives the escape door 24 to be opened. Further, the foregoing collaboration is dominated by the escape cover plate 26, that is, the escape cover plate 26 is opened to drive the escape door 24 to be opened. In this way, when the escape cover plate 26 is opened, an article or a passenger above the escape cover plate 26 can be prevented from falling.
Further, as shown in
Optionally, the escape ladder 27 may be in a fixed state and is always suspending in the escape port 25, and a lower end of the escape ladder 27 and an inner bottom surface of the escape passage 11 are spaced apart, so as to avoid affecting travelling of the rail vehicle 20.
The escape ladder 27 may alternatively have two states, namely, a retraction state and a stretching state, and the vehicle body further includes a stretching/retraction driving device used to drive stretching/retraction of the escape ladder 27. After the escape port 25 is opened, the escape ladder 27 may be manually controlled to stretch into the escape passage 11, or the escape ladder 27 may automatically stretch into the escape passage 11 through collaboration. In this embodiment, after stretching, the escape ladder 27 may be directly placed on the inner bottom surface of the escape passage 11, or the escape ladder 27 and the inner bottom surface of the escape passage 11 may be spaced apart.
Further, the escape cover plate 26 may be pivotably mounted onto the escape door 24. After the escape door 24 is flipped upward and is opened, the escape cover plate 26 rotates collaboratively to be laminated onto the inner surface of the escape door 24, thereby saving space, and preventing the escape cover plate 26 from affecting evacuation of passengers.
In some specific examples of the present disclosure, as shown in
The first rail beam 12 and the second rail beam 13 are disposed in parallel and at an interval, and a bogie 21 straddles the first rail beam 12 and the second rail beam 13. The weight bearing floor 14 is disposed between the first rail beam 12 and the second rail beam 13, the weight bearing floor 14 is connected to the first rail beam 12 and the second rail beam 13, and an escape passage 11 is defined among the first rail beam 12, the second rail beam 13, and the weight bearing floor 14. Therefore, the rail 10 may be provided with the escape passage 11 by using the structure of the rail 10, and no additional component needs to be disposed. Therefore, costs are low, occupied space is small, and it is favorable to reduction in the weight borne by the rail 10. Moreover, the dimension of the rail beam is relatively small, the occupied space area is small, the weight is relatively light, the energy efficiency is high, and the economic performance is good.
Specifically, as shown in
Further, as shown in
Optionally, there is a plurality of connection beams 15 that is spaced apart along the length direction of the rail 10, and there is a plurality of support plates 17 that is sequentially connected along the length direction of the rail 10. On one hand, a single connection beam 15 and a single support plate 17 better facilitate machining, and on the other hand, facilitate entire construction of the rail 10.
A person skilled in the art needs to understand that, sequential connection between the plurality of support plates 17 includes direct connection or indirect connection, and is further direct connection. When the plurality of support plates 17 is indirectly connected, a gap between neighboring support plates 17 needs to ensure that passengers can smoothly stride, that is, does not affect evacuation of the passengers.
Further, the rail 10 further includes an anti-dropping edge 18. Specifically, the anti-dropping edge 18 is disposed at at least one of an upper end and a lower end of at least one of the first rail beam 12 and the second rail beam 13, and the anti-dropping edge 18 extends outward along the horizontal direction and is used to prevent the bogie 21 from being disengaged from the rail 10.

Specifically, the first end 31 of the escape door 24 is disposed adjacent to the vehicle bottom, and the second end 32 of the escape door 24 is disposed adjacent to the vehicle top when the escape door 24 is closed. In other words, when the escape door 24 is closed, the second end 32 of the escape door 24 is located above the first end 31 of the escape door 24; and when the escape door 24 is opened, the second end 32 of the escape door 24 is located below the first end 31 of the escape door 24. Therefore, the escape door 24 is converted from a closed state to an opened state through downward flipping. A flipping-type structure is used for the escape door 24, and the passenger in the vehicle can quickly open the escape door 24 in need of only a simple operation, to effectively improve escape efficiency.
Further, an inner surface of the escape door 24 is provided with a slide rail to help a passenger slide on the slide rail to the escape passage 11.

In this embodiment, after stretching, the escape ladder 27 may be directly placed on the inner bottom surface of the escape passage 11, or the escape ladder 27 and the inner bottom surface of the escape passage 11 may be spaced apart.
Optionally, the escape cover plate 26 may be pivotably mounted onto the escape door 24. After the escape door 24 is flipped upward and is opened, the escape cover plate 26 rotates collaboratively to be laminated onto the inner surface of the escape door 24, thereby saving space, and preventing the escape cover plate 26 from affecting evacuation of passengers.

Specifically, the power battery 28 may be disposed on a position outside the bogie 21. For example, the power battery 28 may be mounted on the bottom of the compartment 23, or may be mounted inside the compartment 23. The power battery 28 can ensure that the rail vehicle is operated at a normal needed speed, and is automatically charged when passenger traffic is relatively small.
In some specific examples of the present disclosure, as shown in
The first support suspension device 910 and the second support suspension device 920 are respectively mounted onto the bogie frame 100 and respectively connected to the vehicle body 22. The first support suspension device 910 and the second support suspension device 920 are spaced apart along the length direction of the rail 10; and in the horizontal plane, the central axis of the first support suspension device 910 and the central axis of the second support suspension device 920 are located on the central axis of the bogie frame 100 and the central axis of the bogie frame 100 equally divides the bogie frame 100 in the width direction of the rail 10.
Alternatively, the first support suspension device 910 and the second support suspension device 920 are spaced apart along the width direction of the rail 10; and in the horizontal plane, the central axis of the first support suspension device 910 and the central axis of the second support suspension device 920 are located on the central axis of the bogie frame 100 and the central axis of the bogie frame 100 equally divides the bogie frame 100 in the length direction of the rail 10.
The first support suspension device 910 and the second support suspension device 920 are used to support the vehicle body 22 and play a role of shock absorption and buffering, and the first support suspension device 910 and the second support suspension device 920 are uniformly loaded and supported, thereby ensuring stability and comfort of the rail vehicle 20. Moreover, costs are relatively low.
For example, the first support suspension device 910 and the second support suspension device 920 may be spaced apart along the length direction of the rail 10 and located on the central axis equally dividing the bogie frame 100 in the width direction of the rail 10 (as shown in
In some other embodiments of the present disclosure, as shown in
The first support suspension device 910, the second support suspension device 920, the third support suspension device 930, and the fourth support suspension device 940 are respectively mounted onto the bogie frame 100 and respectively connected to the vehicle body 22. The first support suspension device 910, the second support suspension device 920, the third support suspension device 930, and the fourth support suspension device 940 are respectively located at four corners of a rectangle in the horizontal plane, and the rectangle is symmetrical about the center of the bogie frame 100, that is, the symmetrical center of the rectangle is the center of the bogie frame 100. In other words, in the horizontal plane, the rectangle is rotated by 180° around the center of the bogie frame 100, and a rectangle formed after rotation coincides with the rectangle before rotation. The first support suspension device 910, the second support suspension device 920, the third support suspension device 930 and the fourth support suspension device 940 are used to support the vehicle body 22 and play a role of shock absorption and buffering, and first support suspension device 910, the second support suspension device 920, the third support suspension device 930 and the fourth support suspension device 940 are uniformly loaded and supported, thereby improving stability and comfort of the rail vehicle 20.
In some embodiments of the present disclosure, as shown in
It can be understood that that, each of the foregoing rectangles is an assumed virtual rectangle, the rectangle is to clearly express an arrangement manner of the first support suspension device 910, the second support suspension device 920, the third support suspension device 930, and the fourth support suspension device 940 in the horizontal plane, and an arrangement manner of the two first horizontal wheels 710 and the two second horizontal wheels in the horizontal plane.
