Further, referring to fig. 2 to 7, when the first track beam and the second track beam are in a passage state, the first communicating member in the first track transfer device is driven by the first driving mechanism to move downwards to be abutted with the notch of the first track beam, so as to form a passage of the first track beam, and at the same time, the second communicating member is driven by the first driving mechanism to move upwards to a set height without interfering the passing of the vehicle on the first track beam; the third communicating member in the second track transfer device moves downwards to be butted with the notch of the second track beam under the driving of the second driving mechanism to form a passage of the second track beam, and at the moment, the fourth communicating member moves upwards to a set height under the driving of the second driving mechanism without interfering the passing of vehicles on the second track beam.
When the guide track beam is in a passage, namely one end of the guide track beam is communicated with the first track beam, and the other end of the guide track beam is communicated with the second track beam, the second communicating member in the first track transfer device moves downwards under the driving of a first driving mechanism to be butted with a gap between the first track beam and the guide track beam to form a passage between the guide track beam and the first track beam, and at the moment, the first communicating member moves upwards under the driving of the first driving mechanism to a set height which is far away from the first track beam and does not interfere with the running of a train; the fourth communicating member in the second track transfer device moves downwards under the driving of the second driving mechanism to be in butt joint with the second track beam and the notch between the guide track beams to form a passage between the guide track beams and the second track beam, and at the moment, the third communicating member moves upwards under the driving of the second driving mechanism to a set height which is far away from the second track beam and does not interfere with the running of the train.
In the invention, the first track-changing device and the second track-changing device control the linear track beam and the guide track beam to have only one passage at the same time, so that a train can continuously pass through the branch road port, and track line change can be rapidly carried out without stopping at the branch road port to wait for track communication; when a train is positioned on the first track beam or the second track beam and needs to continuously run along the first track beam or the second track beam, the first track transfer device and the second track transfer device are in a state that the first track beam or the second track beam is communicated with each other in a default state, and track changing is not needed, namely, a driving device can finish quick passing of the train at a track intersection without action.
Preferably, a reinforcing rib can be additionally arranged between the first connecting part and the first track part in the first track transfer device, so that the bearing capacity of the first track part is improved, a stress monitoring device can be further arranged between the first connecting part and the first track part, when the stress is detected to exceed a preset value, a system finds an alarm signal, so that personnel can monitor the structural strength of the switching part in time, and the safety of the track transfer device is enhanced; similarly, the second connecting portion and the second track portion, the third connecting portion and the third track portion, and the fourth connecting portion and the fourth track portion may be equally disposed, and are not repeated here.
Preferably, a notch is reserved at each structure position of the theoretically superposed position of the first communicating member and the second communicating member, so that the first communicating member and the second communicating member do not interfere with each other when moving in opposite directions; and a notch is reserved at the structure of each of the theoretically superposed positions of the third communicating member and the fourth communicating member, so that the third communicating member and the fourth communicating member do not interfere with each other when moving in opposite directions.
Further, in the first track transfer device, the first connecting portion of the first communicating member, which is butted against the web, may carry a static load and a moving load of the first communicating member; when the first track beam is in a self-communication state, namely when the first communication member descends to a lower limit point and is in butt joint with the notch on the first track beam, when a bogie of a train passes through the first track part of the first communication member, the first track part transmits pressure to the first connection part through a vertical limiting member (not shown) between the first connection part and the first connection part, and because the width of the first connection part is greater than that of the first track part, the pressure on the first connection part can transmit force to the first track beam through the connection part and a self structure; meanwhile, the side of the first connecting part facing the train bogie can bear the load from the transverse direction of the train bogie and transmit the transverse load to the first track beam main body through a transverse limiting component (not shown) arranged on the first track beam; in the invention, the load pressure borne by the first track transfer device in a working state can be transmitted to the first track beam main body through the arranged vertical limiting members and the transverse limiting members, so that the structural safety performance of the first track transfer device is further improved; similarly, the second communicating member in the first rail transfer device, the third communicating member in the second rail transfer device and the fourth communicating member are provided with vertical and transverse members which have the same function as the first communicating member, that is, when the rail parts in different communicating members are in a state of being overlapped and butted with the rail surface, the load force from the train bogie is transmitted to the rail beam main body through the limiting members by each rail part and each connecting part, the load bearing of the rail transfer device is dispersed, and therefore the more reliable structural safety of the rail transfer device is achieved.
Further, taking the first track-changing device as an example, when the first track part is at the lower limit position and is in overlapped butt joint with the track surface of the first track beam, the first track beam is in a passage state, and a train can pass along the first track beam; at the moment, the first track beam locks the first track part through a first locking device, so that the stability and the safety performance of a butt joint are further ensured, and after a train passes through the first track beam, the first locking device releases the first track surface; similarly, the second communicating member in the first rail transfer device, the third communicating member in the second rail transfer device and the fourth communicating member are respectively provided with a locking device which has the same function as that of the first communicating member, namely when the rail parts in different communicating members are in a state of being overlapped and butted with the rail surface, the corresponding locking devices lock the corresponding rail parts, and further guarantee of the structural safety performance of a butted area is realized; the first action set, the second action set, locking and releasing of the double-line track beam are all controlled by an operation management system in the suspension air-rail system.
In the present invention, the N-shaped double-track beam based on the double-turnout structure, which is composed of the first track beam, the second track beam and the guide track beam, includes the following three different structural embodiments, in order to highlight the connection design among the first track beam, the second track beam and the guide track beam, the first track transfer device and the second track transfer device are not shown in the following three embodiments, and the following description is made with reference to the drawings.
