Abstract

The present disclosure discloses a rail transport system. The rail transport system includes: a rail, the rail includes a steering portion and a travelling portion, the travelling portion is connected to the steering portion, and a first recess is constructed on the travelling portion to form an escape passage; and a rail vehicle, where the rail vehicle includes bogies and a vehicle body, the bogie movably straddles the rail, the bogie fits in with an inner bottom surface of the escape passage of the travelling portion and the steering portion, and the bogie travels by using the travelling portion and is steered by using the steering portion, and the vehicle body is connected to the bogie and pulled by the bogie to travel along the rail. The rail transport system 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.

First claim

What is claimed is:

1. A rail transport system, comprising:
a rail, wherein the rail comprises a steering portion and a travelling portion, the travelling portion is connected to the steering portion, and a first recess is constructed on the travelling portion to form an escape passage; and
a rail vehicle, wherein the rail vehicle comprises a bogie and a vehicle body, the bogie movably straddles the rail, the bogie fits in with an inner bottom surface of the escape passage of the travelling portion and the steering portion, and the bogie travels by using the travelling portion and is steered by using the steering portion, and the vehicle body is connected to the bogie and pulled by the bogie to travel along the rail,
wherein:
the vehicle body comprises a plurality of compartments hinged sequentially along a length direction of the rail;
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; and
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, wherein 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.

2. The rail transport system according to claim 1 , wherein the bogie is provided with a first dodge groove and a second dodge groove used to respectively dodge two side walls of the escape passage.

3. The rail transport system according to claim 2 , 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 escape passage when the escape door is opened.

4. The rail transport system according to claim 3 , wherein an inner surface of the escape door is provided with a slide rail.

5. The rail transport system according to claim 1 , wherein
an escape ladder leading to the escape passage 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.

6. The rail transport system according to claim 1 , wherein the travelling portion comprises:
a bottom plate, wherein the bottom plate is connected to the steering portion; and
a first side plate and a second side plate, wherein the first side plate and the second side plate are connected to the bottom plate and are spaced apart along a width direction of the bottom plate, the escape passage is defined among the first side plate, the second side plate, and the bottom plate, the bottom plate forms a bottom wall of the escape passage, and the first side plate and the second side plate respectively form two side walls of the escape passage.

7. A rail transport system, comprising:
a rail, wherein the rail comprises a steering portion and a travelling portion, the travelling portion is connected to the steering portion, and a first recess is constructed on the travelling portion to form an escape passage; and
a rail vehicle, wherein the rail vehicle comprises a bogie and a vehicle body, the bogie movably straddles the rail, the bogie fits in with an inner bottom surface of the escape passage of the travelling portion and the steering portion, and the bogie travels by using the travelling portion and is steered by using the steering portion, and the vehicle body is connected to the bogie and pulled by the bogie to travel along the rail,
wherein the travelling portion comprises:
a bottom plate, wherein the bottom plate is connected to the steering portion; and
a first side plate and a second side plate, wherein the first side plate and the second side plate are connected to the bottom plate and are spaced apart along a width direction of the bottom plate, the escape passage is defined among the first side plate, the second side plate, and the bottom plate, the bottom plate forms a bottom wall of the escape passage, and the first side plate and the second side plate respectively form two side walls of the escape passage,
wherein a longitudinal central axis of a cross section of the travelling portion coincides with a longitudinal central axis of a cross section of the steering portion, and the width of the bottom plate is greater than the width of the steering portion.

8. The rail transport system according to claim 7 , wherein a minimum distance between the first side plate and the second side plate is greater than the width of the steering portion.

9. The rail transport system according to claim 8 , wherein the first side plate and the second side plate are respectively connected to two side edges of the bottom plate.

10. The rail transport system according to claim 7 , wherein the thickness of a part of the bottom plate connected to the steering portion is greater than the thickness of a remaining part of the bottom plate.

11. The rail transport system according to claim 7 , wherein the bogie comprises:
a bogie frame, wherein the bogie frame has a second recess straddling the rail; and the bogie frame is provided with a first dodge groove and a second dodge groove, the first side plate stretches into the first dodge groove, and the second side plate stretches into the second dodge groove;
at least one running wheel, wherein the running wheel is pivotably mounted onto the bogie frame and fits in on the bottom plate, and the running wheel is located between the first side plate and the second side plate and is located right above the steering portion; and
a driving device, wherein the driving device is mounted onto the bogie frame and the running wheel is driven by the driving device.

12. The rail transport system according to claim 11 , wherein the bogie frame 100 is provided with a running wheel mounting groove located between the first dodge groove and the second dodge groove, and the running wheel is pivotably mounted into the running wheel mounting groove.

13. The rail transport system according to claim 11 , wherein the at least one running wheel includes a plurality of running wheels,
