Abstract

The present disclosure discloses a rail vehicle. 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 rail vehicle according to this embodiment of the present disclosure facilitates optimization of the structure of an escape passage, reduction in costs, reduction in occupied space and the weight borne by the rail, and improvement in stability, and is high in stability of supporting the vehicle body and large in passenger capacity.

First claim

What is claimed is:

1. A rail vehicle, comprising:
a plurality of bogies, wherein the bogie has a straddle recess suitable for straddling a rail; and
a vehicle body, wherein 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 comprises 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,
wherein the bogie comprises:
a bogie frame, wherein the straddle recess is disposed on the bogie frame;
a first running wheel and a second running wheel, wherein the first running wheel and the second running wheel are pivotably mounted onto the bogie frame respectively and are coaxially spaced apart; and
a driving device, wherein the driving device is mounted onto the bogie frame and is located between the first running wheel and the second running wheel, and the first running wheel and the second running wheel are driven by the driving device.

2. The rail vehicle according to claim 1 , wherein the bottom of each of the compartments is connected to one of the bogies, and one bogie on the bottom of each of the compartments is located in the middle of the compartment along the length direction of the rail.

3. The rail vehicle according to claim 2 , wherein the neighboring compartments are hinged at a lower portion and flexibly connected at an upper portion.

4. The rail vehicle according to claim 1 , wherein the bottom of each of the compartments is connected to two of the bogies, and the two bogies on the bottom of each of the compartments are respectively located at two ends of the compartment along the length direction of the rail.

5. The rail transport system according to claim 1 , wherein one bogie is disposed on a hinging position of neighboring compartments and the neighboring compartments are hinged by sharing the one bogie.

6. The rail transport system according to claim 5 , wherein each of compartments at two ends of the vehicle body is further provided with one unshared bogie.

7. The rail vehicle according to claim 1 , wherein neighboring compartments are further flexibly connected.

8. The rail vehicle according to claim 1 , wherein a first end of the escape door is pivotably mounted onto the corresponding compartment, and a second end of the escape door tilts downward and stretches into the rail when the escape door is opened.

9. The rail vehicle according to claim 8 , wherein an inner surface of the escape door is provided with a slide rail.

10. The rail vehicle according to claim 1 , wherein an escape port and an escape cover plate are disposed on an inner floor of the compartment at the at least one end of the vehicle body, the escape cover plate collaborates with the escape door and is used to open and close the escape port, the escape cover plate opens the escape port when the escape door is opened, and the escape cover plate closes the escape port when the escape door is closed.

11. The rail vehicle according to claim 10 , wherein an escape ladder leading to the rail is disposed in the escape port, and the vehicle body further comprises a stretching/retraction driving device used to drive stretching/retraction of the escape ladder.

12. The rail vehicle according to claim 1 , wherein the bogie comprises:
a third running wheel and a fourth running wheel, wherein the third running wheel and the fourth running wheel are pivotably mounted onto the bogie frame respectively and are coaxially spaced apart, the third running wheel and the first running wheel are spaced apart in the length direction of the rail, and the fourth running wheel and the second running wheel are spaced apart in the length direction of the rail.

13. The rail vehicle according to claim 12 , wherein the first running wheel and the second running wheel are connected by using a first connection shaft and/or the third running wheel and the fourth running wheel are connected by using a second connection shaft; and the at least one driving device is in transmission connection to the first connection shaft or the second connection shaft.

14. The rail vehicle according to claim 12 , wherein the first driving device is closer to the first running wheel than the second running wheel, or the second driving device is closer to the fourth running wheel than the third running wheel.

15. The rail vehicle according to claim 1 , wherein the bogie further comprises:
a first horizontal wheel, wherein the first horizontal wheel is pivotably mounted onto the bogie frame and is suitable for fitting in on a first side surface of the rail; and
a second horizontal wheel, wherein the second horizontal wheel is pivotably mounted onto the bogie frame and is suitable for fitting in on a second side surface of the rail.

16. The rail vehicle according to claim 15 , wherein the first horizontal wheel is connected to a first horizontal safety wheel that moves in synchronization with the first horizontal wheel and whose outer diameter is less than the outer diameter of the first horizontal wheel, and the second horizontal wheel is connected to a second horizontal safety wheel that moves in synchronization with the second horizontal wheel and whose outer diameter is less than the outer diameter of the second horizontal wheel.

17. The rail vehicle according to claim 15 , wherein the first horizontal wheel is suitable for fitting in on a first outer side surface of the rail and the second horizontal wheel is suitable for fitting in on a second outer side surface of the rail.

18. The rail vehicle according to claim 15 , wherein the first horizontal wheel is suitable for fitting in on a first inner side surface of the rail and the second horizontal wheel is suitable for fitting in on a second inner side surface of the rail.

19. The rail vehicle according to claim 15 , wherein the first horizontal wheel and the second horizontal wheel are located at a same height in an up and down direction.
