The present invention is based on the inventors of the present application's discovery of the following facts and problems:

In the straddle type monorail train in the related art, in order to facilitate the evacuation of passengers in an emergency, an independent escape passage is provided. Specifically, by additionally providing a frame on the track, the frame is usually connected to the side of the track and protrudes outward, and then a floor is laid on the frame to form a passageway for evacuating passengers.

The inventors of the present application have found through a large number of researches and experiments that the straddle-type monorail trains with escape routes in the related art have the disadvantages of high cost, large space occupation, and hidden dangers in stability. The specific reasons are as follows:

Since the frame and the floor laid on it are additional additional structures independent of the track, and the location of the emergency situation during the driving of the vehicle cannot be predicted, it needs to be installed along the entire length of the track (except at the platform) The extra escape passage of this structure is huge, which not only greatly increases the cost, but also the frame and floor are located on the side of the track, which is equivalent to extending an additional part in the width direction of the track, which takes up a lot of space. In addition, the frame and the floor itself have a certain weight, regardless of whether the vehicle is in an emergency, the frame and the floor are erected on the track, that is to say, even if the vehicle is running normally, the track still has to carry the weight of the frame and the floor, which increases the The bearing weight of the track has an adverse effect on the stability of the track.

Considering the status of straddle-type monorail trains in the related art, the present invention proposes a rail transit system 1 that is convenient for evacuating passengers in emergency situations, and has the advantages of low cost, small space occupation, small track load bearing, and high stability.

A rail transit system 1 according to an embodiment of the present invention will be described below with reference to the accompanying drawings.

As shown in FIGS. 1-32 , a rail transit system 1 according to an embodiment of the present invention includes a rail 10 and a rail vehicle 20 .

The track 10 includes a turning part 111 and a running part 112 , the running part 112 is connected to the top of the turning part 111 and a concave part is configured on the running part 112 to form the escape passage 11 .

According to the rail transit system 1 of the embodiment of the present invention, by setting the escape passage 11 on the track 10 itself, when an emergency occurs, the passengers can be evacuated in time through the escape passage 11 . And, since the escape passage 11 is arranged on the track 10 itself, there is no need to add other additional structures on the track 10, it is only necessary to set the escape passage 11 on the track 10 itself along its length direction, thus greatly reducing the engineering cost. On the one hand, the cost is reduced, and on the other hand, the occupied space is reduced. Moreover, there is no need to increase the load bearing of the track 10 , which is beneficial to the stability of the track 10 . Therefore, the rail transit system 1 according to the embodiment of the present invention has the advantages of being convenient for evacuating passengers in an emergency, low cost, small space occupation, small rail load bearing, and high stability.

The escape cover 26 is linked with the escape door 24 and is used to open and close the escape opening 25 . When the rail vehicle 20 is running normally, the escape door 24 is closed and the escape cover 26 closes the escape opening 25 (as shown in FIG. 26 ). When an emergency occurs, the rail vehicle 20 stops actively or passively, the escape door 24 is opened and the escape cover 26 opens the escape opening 25 (as shown in Figure 27 ), and the passengers in the compartment 23 can enter the escape passage 11 through the escape opening 25, Then evacuate from the escape route 11. In addition, even if the rail vehicle 20 is forced to stop at the turn of the track 10, since the escape door 24 does not need to cooperate with the track 10 when it is opened, it will not collide with the track 10, which is convenient for passengers to evacuate at the turn of the track 10.

Preferably, in the length direction of the track 10, the two compartments 23 located at both ends of the car body 22 are provided with escape doors 24.
