This application is a national phase entry under 35 U.S.C. § 371 of International Application No. PCT/CN2017/075167, filed on Feb. 28, 2017, which claims priority to Chinese Patent Application No. 201610839745.6, filed on Sep. 21, 2016, Chinese Patent Application No. 201610841071.3, filed on Sep. 21, 2016, and Chinese Patent Application No. 201610840581.9, filed on Sep. 21, 2016, all of which are incorporated herein by reference in their entireties.
The present disclosure relates to the field of transport technologies and, specifically, to a rail vehicle.
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 added structures independent of the rail, and a specific location of a 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 a portion additionally 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.
An objective of the present disclosure is to resolve at least one of the foregoing technical problems in the related art to some extent.
To achieve the foregoing objective, according to an embodiment of the present disclosure, a rail vehicle is provided. The rail vehicle includes: a plurality of bogies, where the bogie has a straddle recess suitable for straddling a rail; and a vehicle body, where the vehicle body is connected to the plurality of bogies and pulled by the plurality of bogies to travel along the rail, and the vehicle body includes a plurality of compartments hinged sequentially along a length direction of the rail; at least one bogie is disposed on one of the bottom of each of the compartments and a hinging position of neighboring compartments; and in the length direction of the rail, a surface that is of a compartment at at least one end of the vehicle body and that faces away from an adjacent compartment is provided with an escape door that can be opened and closed.

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 proposes 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 a plurality of bogies 21 and a vehicle body 22, the plurality of bogies 21 respectively movably straddles the rail 10, and the bogie 21 has a second recess 110 used for straddling the rail 10. Specifically, the second recess 110 is a straddle recess. The vehicle body 22 is connected to the plurality of bogies 21 and pulled by the plurality of bogies 21 to travel along the rail 10. 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
Alternatively, the bottom of each compartment 23 is connected to two bogies 21. Among the plurality of compartments 23, in the length direction of the rail 10, a surface that is of a compartment 23 at at least one end of the vehicle body 22 and that faces away from an adjacent compartment 23 is provided with an escape door 24 that can be opened and closed.
It may be understood that, the bottom of a single compartment 23 may be provided with one or more bogies 21.
Herein, 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 bottom of a single compartment 23 is provided with two bogies 21. Such a bogie arrangement manner supports the vehicle body 22 more stably, so that the structural stability of the rail vehicle 20 is higher. Moreover, it is convenient to place the running wheel of the bogie 21 below the floor in the compartment 23, so that the design in the compartment 23 is more concise, and the number of passengers is effectively increased.
The rail transport system 1 according to a specific embodiment of the present disclosure is described below with reference to accompanying drawings.

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.
The present disclosure further proposes 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 a plurality of bogies 21 and a vehicle body 22, the plurality of bogies 21 respectively movably straddles the rail 10, and the bogie 21 has a second recess 110 used for straddling the rail 10. The vehicle body 22 is connected to the plurality of bogies 21 and pulled by the plurality of bogies 21 to travel along the rail 10.
The vehicle body 22 includes a plurality of compartments 23 hinged sequentially along a length direction of the rail 10, the bottom of each compartment 23 is connected to two bogies 21, and neighboring compartments 23 are hinged by sharing one bogie 21. In other words, a bogie 21 between two neighboring compartments 23 is hinged to the two neighboring compartments 23. To be specific, two neighboring compartments 23 share one bogie 21. It can be understood that, the bottom of each of two compartments 23 located at two ends of the vehicle body 22 is further provided with one unshared bogie 21, to ensure stability of the vehicle head and the vehicle tail of the vehicle body 22. Moreover, among the plurality of compartments 23, in the length direction of the rail 10, a surface that is of a compartment 23 at at least one end of the vehicle body 22 and that faces away from an adjacent compartment 23 is provided with an escape door 24 that can be opened and closed.

Further, neighboring compartments 23 are further flexibly connected. For example, two neighboring compartments 23 are hinged on the bottom of opposite end surfaces of the two compartments 23 by sharing one bogie 21 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.
It can be understood 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 anti-dropping edge 18 may be disposed on the top and/or the bottom of the first rail beam 12, and may be disposed on an outer side surface and/or an inner side surface of the first rail beam 12; or the anti-dropping edge 18 may be disposed on the top and/or the bottom of the second rail beam 13, and may be disposed on an outer side surface and/or an inner side surface of the second rail beam 13. Herein, it can be understood that, the anti-dropping edge 18 is disposed to prevent the bogie 21 from being disengaged from the rail 10, thereby ensuring stability of the rail vehicle 20 in a travelling situation such as bending, and therefore, a partial structure of the bogie 21 needs to be placed right below the anti-dropping edge 18 on the top and/or right above the anti-dropping edge 18 on the bottom.

The bogie frame 100 has a second recess 110 suitable for straddling the rail 10, that is, the second recess 110 is disposed on the bogie frame 100. The second recess 110 is a straddle recess. Specifically, the second recess 110 is formed by a hollow portion jointly defined by the bottom of the bogie frame 100, a first horizontal wheel 710, and a second horizontal wheel 720, and the innermost sides of the first horizontal wheel 710 and the second horizontal wheel 720 is in contact with the outer side of the rail 10. The first running wheel 210 and the second running wheel 220 are pivotably mounted onto the bogie frame 100 respectively and are coaxially spaced apart. The first running wheel 210 fits in on an upper surface of the first rail beam 12, and the second running wheel 220 fits in on an upper surface of the second rail beam 13. The driving device 300 is mounted onto the bogie frame 100, and the driving device 300 is located between the first running wheel 210 and the second running wheel 220. The first running wheel 210 and the second running wheel 220 are driven by the driving device 300, and under driving of the driving device 300, the first running wheel 210 and the second running wheel 220 drives the bogie 21 to run along the rail 10, thereby pulling the vehicle body 22 to travel. Therefore, the driving device 300 may be mounted by using the gap between the first running wheel 210 and the second running wheel 220, so as to save space, improve space utilization, and facilitate distribution of the center of gravity of the vehicle body 22, and moreover a center distance of a tyre may be increased, to improve uniform stability of driving of the driving device 300 for the first running wheel 210 and the second running wheel 220, thereby improving stability and comfort of the rail transport system 1.
