[0049] In order to more clearly understand the present invention, the first track-changing device and the second track-changing device are first described in detail below.

[0050] See attached Figure 4 and attached Figure 5 ,in, Figure 4 is a front view of the first track changing device, Figure 5: is a schematic diagram of the three-dimensional structure of the first track-changing device, the first track-changing device includes a first connecting member 61 and a second connecting member 62; the first connecting member 61 is used to control the on-off of the first track beam itself, the first connecting member includes a first connecting portion and a first track portion, the first track portion is horizontally arranged and used to dock with the running board of the first track beam, the first connecting portion is vertically fixedly connected to the first track portion, and used to dock with the web of the first track beam, the two ends of the first connecting member composed of the first connecting portion and the first track portion are consistent with the waiting docking position setting of the running board and the web of the first track beam; the second connecting member 62 is used to control the on-off between the first track beam and the guide track beam, the second connecting member includes a second connecting portion and a second track portion, the second track portion is horizontally arranged and used to dock with the running board of the guide track beam, the second connecting portion is vertically fixedly connected to the second track portion, the second connecting portion is arranged at the same arc surface as the docking position of the guide track beam, and is used to dock with the web of the guide track beam, the two ends of the second connecting member composed of the second connecting portion and the second track portion are consistent with the waiting docking position setting of the running board and the web of the guide track beam.

[0051] See attached Figure 6 and attached Figure 7 ,in, Figure 6 is a front view of the second track changing device, Figure 7 : is a schematic diagram of the three-dimensional structure of the second track-changing device, the second track-changing device includes a third connecting member 71 and a fourth connecting member 72; the third connecting member 71 is used to control the on-off of the second track beam itself, the third connecting member includes a third connecting portion and a third track portion, the third track portion is horizontally arranged and used to dock with the walking plate of the second track beam, the third connecting portion is vertically fixedly connected to the third track portion, and is used to dock with the web of the second track beam, and the two ends of the third connecting member composed of the third connecting portion and the third track portion are connected to the waiting docking position of the walking plate and the web of the second track beam The fourth connecting member 72 is used to control the connection between the second track beam and the guide track beam, and the fourth connecting member includes a fourth connecting portion and a fourth track portion. The fourth track portion is horizontally arranged and used to dock with the walking plate of the guide track beam. The fourth connecting portion is vertically fixedly connected to the fourth track portion. The fourth connecting portion is arranged with the same arc surface as the guide track beam at the docking position, and is used to dock with the web of the guide track beam. The two ends of the fourth connecting member composed of the fourth connecting portion and the fourth track portion are consistent with the docking position of the walking plate and the web of the guide track beam.

[0052] Furthermore, the first track-changing device and the second track-changing device also include a support rod, a liftable component and a driving mechanism. The support rod is fixed on the track beam, the liftable component is connected to the support rod, and the liftable device includes a first component and a second component. The second component can be slid up and down relative to the first component, and the second component is fixedly connected to the track-changing device. Under the drive of the driving mechanism, the track-changing device is driven to move up and down to achieve the connection with the corresponding track beam. The driving mechanism can be a hydraulic driving mechanism, a pneumatic driving mechanism, a linear motor driving mechanism, a rotary motor driving mechanism, a gear rack mechanism, etc. As long as it can achieve the purpose of driving the track-changing device to move up and down, they are all acceptable and will not be described one by one here.

[0053] Further, see Attachment Figure 2 To Attachment Figure 7 When the first track beam and the second track beam are in a passage state, the first connecting component in the first track changing device moves downward under the drive of the first driving mechanism to dock with the notch of the first track beam, forming a passage for the first track beam itself. At this time, the second connecting component moves upward to a set height under the drive of the first driving device, and does not interfere with the passage of vehicles on the first track beam; the third connecting component in the second track changing device moves downward under the drive of the second driving mechanism to dock with the notch of the second track beam, forming a passage for the second track beam itself. At this time, the fourth connecting component moves upward to a set height under the drive of the second driving device, and does not interfere with the passage of vehicles on the second track beam.

[0054] When the guide track beam is in the passage, that is, one end of the guide track beam is connected to the first track beam, and the other end of the guide track beam is connected to the second track beam, the second connecting component in the first track changing device moves downward under the drive of the first driving mechanism to the gap between the first track beam and the guide track beam to dock with each other, thereby forming a passage between the guide track beam and the first track beam. At this time, the first connecting component moves upward under the drive of the first driving mechanism to a set height away from the first track beam and not interfering with the train operation; the fourth connecting component in the second track changing device moves downward under the drive of the second driving mechanism to dock with the gap between the second track beam and the guide track beam to form a passage between the guide track beam and the second track beam. At this time, the third connecting component moves upward under the drive of the second driving device to a set height away from the second track beam and not interfering with the train operation.

[0055] In the present invention, the first track-changing device and the second track-changing device control the straight track beam and the guide track beam to have only one in the passage at the same time, so as to ensure that the train passes continuously when passing through the fork intersection, and the track line can be changed quickly without stopping at the forked track entrance to wait for the track to be connected; when the train is located on the first track beam or the second track beam, and needs to continue to run along the first track beam or the second track beam, the first track-changing device and the second track-changing device are in a state where the first track beam or the second track beam is connected to itself in the default state, and there is no need to change lanes, that is, the driving device does not need to act to complete the rapid passage of the train at the track fork.

[0056] Preferably, reinforcing ribs may be added between the first connecting part and the first track part in the first track changing device to improve the bearing capacity of the first track part. A stress monitoring device may also be arranged between the first connecting part and the first track part. When it is detected that the stress exceeds a preset value, the system sends an alarm signal to facilitate personnel to monitor the structural strength of the transition point in time and enhance the safety of the track changing device. Similarly, the second connecting part and the second track part, the third connecting part and the third track part, and the fourth connecting part and the fourth track part may be arranged in the same way, which will not be described one by one here.

[0057] Preferably, a notch is left at the structure where the first connecting member and the second connecting member theoretically overlap, to ensure that the first connecting member and the second connecting member do not interfere with each other when they move in opposite directions; a notch is left at the structure where the third connecting member and the fourth connecting member theoretically overlap, to ensure that the third connecting member and the fourth connecting member do not interfere with each other when they move in opposite directions.

[0058] Furthermore, in the first track-changing device, the first connecting portion of the first connecting member that is docked with the web can bear the static load and the moving load of the first connecting member; when the first track beam is in a self-connected state, that is, when the first connecting member is lowered to the lower limit position and docked with the notch on the first track beam, when the bogie of the train passes through the first track portion of the first connecting member, the first track portion transmits pressure to the first connecting portion through a vertical limiting member (not shown) between the first connecting portion and the first connecting portion. Because the width of the first connecting portion is greater than the width of the first track portion, the pressure on the first connecting portion can be transmitted to the first track beam through the connecting member and its own structure; at the same time, the side of the first connecting portion facing the train bogie can bear the lateral load from the train bogie, and transmit the pressure to the first track beam through the first A transverse limiting member (not shown) arranged on the track beam transfers the transverse load to the first track beam body; in the invention, the load pressure borne by the first track changing device in the working state can be transferred to the first track beam body through the various vertical limiting members and transverse limiting members, thereby further improving the structural safety performance of the first track changing device; similarly, the second connecting member in the first track changing device, the third connecting member in the second track changing device and the fourth connecting member are all provided with vertical and transverse members that play the same role as the first connecting member, that is, when the track parts in different connecting members are in a state of overlapping and docking with the track surface, each track part and each connecting part transfers the load force from the train bogie to the track beam body through the limiting member, thereby dispersing the load-bearing load of the track changing device, thereby achieving more reliable structural safety of the track changing device.

[0059] Furthermore, taking the first track-changing device as an example, when the first track portion is at the lower limit position and coincides with the track surface of the first track beam, the first track beam itself is in a passage state, and the train can pass along the first track beam; at this time, the first track beam locks the first track portion through the first locking device, further ensuring the stability and safety performance of the docking point, and when the train passes through the first track beam, the first locking device releases the first track surface; similarly, the second connecting component in the first track-changing device, the third connecting component in the second track-changing device, and the fourth connecting component are all provided with locking devices that play the same role as those in the first connecting component, that is, when the track portions in different connecting components are in a state of coincidence and docking with the track surface, the corresponding locking devices lock the corresponding track portions, thereby further ensuring the structural safety performance of the docking area; the first action set, the second action set, locking, and releasing of the double-track track beam are all controlled by the operation management system in the suspended air-rail system.

[0060] In the present invention, the N-shaped double-track track beam based on the double turnout structure 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 between the first track beam, the second track beam and the guide track beam, the first track changing device and the second track changing device are not shown in the following three embodiments.
