[0063] See attached Fig.12, the figure is a schematic diagram of the three-dimensional structure of the switch device, the switch device includes a transition track beam 111, a connecting device 112 and a locking device 113, both ends of the transition track beam 111 are arc-shaped cross-sections, and arc-shaped closing plates 114 are arranged on the left and right sides of the end of the transition track beam 111, and the arc-shaped closing plate and the end arc surface of the transition track beam are arranged on the same cylindrical surface, the switch device includes four arc-shaped closing plates, that is, the outer arc surfaces of the four arc-shaped closing plates and the two end arc surfaces of the transition track beam are on the same cylindrical surface, in the present invention, the cylindrical surface and the cylindrical surface formed by the first guide track beam, the second guide track beam, the third guide track beam, and the fourth guide track beam away from the track beam are concentric cylindrical surfaces, and the small gap between the two cylindrical surfaces does not affect the passage of the train after the switch device is connected with each guide track beam;

[0064] The connecting device 112 is rotatably arranged above the transition track beam and fixedly connected to the top plate of the double-track double-open track beam. The spacing between the top plate of the double-track double-open track beam and the switch device does not affect the rotation of the switch device.

The racks 115 are used to mesh with the gears arranged in the top plate of the double-track double-open track beam and realize the rotation of the transition track beam under the drive of the gears.

[0065] The locking device 113 is arranged on the outer side of the arc-shaped closing plate, and is used to lock the transition track beam after the transition track beam and the guide track beam are docked and connected. The switch device includes four locking devices. When the switch device rotates to a preset position during operation, the position sensor arranged on the switch device is triggered, and then the switch device is locked by the four locking devices 113. In this embodiment, after the position sensors arranged on the same diagonal line sense, it is ensured that the switch device is rotated into place, and then the position of the switch device is fixed by the locking device, so as to ensure that the switch device is accurately docked and connected with the corresponding guide track beam; when the switch device receives an instruction from the system that no train passes through this locked position in the next step, the locking device releases the transition track beam after the train passes.

[0066] Further, please refer to the attached Figure 1 To Attachment Fig.12When the first track beam is in its own 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 same plane height as the notch of the first track beam, and at the same time, the seventh connecting component in the fourth track changing device moves downward under the drive of the fourth driving mechanism to dock with the same plane height as the notch of the first track beam, forming the passage of 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 the eighth connecting component moves upward to a set height under the drive of the fourth driving device, without interfering with the passage of vehicles on the first track beam.

[0067] When the second track beam is in its own passage state, 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 at the same plane height, and at the same time, the fifth connecting component in the third track changing device moves downward under the drive of the third driving mechanism to dock with the notch of the second track beam at the same plane height, thereby forming the passage of the second track beam itself; at this time, the fourth connecting component moves upward to the set height under the drive of the second driving device, and the sixth connecting component moves upward to the set height under the drive of the third driving device, without interfering with the passage of vehicles on the second track beam.

[0068] When the first guide track beam and the third guide track beam are in a passage state, that is, one end of the first guide track beam is connected to the first track beam, the other end of the first guide track beam is connected to the third guide track beam through the switch device, and the end of the third guide track beam away from the switch device 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 dock with the same plane height as the gap between the first track beam and the first guide track beam, and at the same time, the sixth connecting component in the third track changing device moves downward under the drive of the third driving mechanism to dock with the gap between the second track beam and the third guide track beam. The notches are butt-jointed at the same plane height, and the switch device is rotated to butt with the first guide track beam and the third guide track beam, at which time a passage is formed between the first track beam, the first guide track beam, the third guide track beam and the second track beam, so that the track line change from the first track beam or the second track beam can be realized; at the same time, the first connecting component in the first track changing device moves upward to a set height under the drive of the first driving device, and the fifth connecting component in the third track changing device moves upward to a set height under the drive of the third driving device, without interfering with the passage of vehicles between the first track beam, the first guide track beam, the third guide track beam and the second track beam.

[0069] When the second guide track beam and the fourth guide track beam are in a passage state, that is, one end of the fourth guide track beam is connected to the first track beam, the other end of the fourth guide track beam is connected to the second guide track beam through the switch device, and the end of the second guide track beam away from the switch device is connected to the second track beam. At this time, the eighth connecting component in the fourth track changing device moves downward under the drive of the fourth driving mechanism to dock with the same plane height as the gap between the first track beam and the fourth guide track beam, and at the same time, 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 second guide track beam. The switch device is connected at the same plane height as the second guide track beam and the fourth guide track beam, and a passage is formed between the first track beam, the fourth guide track beam, the second guide track beam and the second track beam, so that the track line change from the first track beam or the second track beam can be realized; at the same time, the seventh connecting component in the fourth track changing device moves upward to a set height under the drive of the fourth driving device, and the third connecting component in the second track changing device moves upward to a set height under the drive of the second driving device, without interfering with the passage of vehicles between the first track beam, the fourth guide track beam, the second guide track beam and the second track beam.

[0070] In the present invention, the first track-changing device, the second track-changing device, the third track-changing device, the fourth track-changing device and the switch 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 quickly changed 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, the second track-changing device, the third track-changing device and the fourth track-changing device are in the state of being connected to the first track beam or the second track beam by default. State, that is, in the default state, the first connecting component of the first track-changing device, the third connecting component of the second track-changing device, the fifth connecting component of the third track-changing device, and the seventh connecting component of the fourth track-changing device are at the lower limit position and are connected with the straight track beam, and the second connecting component of the first track-changing device, the fourth connecting component of the second track-changing device, the sixth connecting component of the third track-changing device, and the eighth connecting component of the fourth track-changing device are at the upper limit position, away from the first track beam and the second track beam, and do not affect the passage of the train. At this time, 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.

[0071] 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, which is convenient for 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, the fourth connecting part and the fourth track part, the fifth connecting part and the fifth track part, the sixth connecting part and the sixth track part, the seventh connecting part and the seventh track part, and the eighth connecting part and the eighth track part may be arranged in the same way, and they will not be described one by one here.

[0072] Preferably, a notch is left in the respective structures 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 in the respective structures 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; a notch is left in the respective structures where the fifth connecting member and the sixth connecting member theoretically overlap, to ensure that the fifth connecting member and the sixth connecting member do not interfere with each other when they move in opposite directions; a notch is left in the respective structures where the seventh connecting member and the eighth connecting member theoretically overlap, to ensure that the seventh connecting member and the eighth connecting member do not interfere with each other when they move in opposite directions.

[0073] 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 lateral load to the first bogie through the lateral limiting member (not shown) provided on the first track beam. A 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 components and transverse limiting components, thereby further improving the structural safety performance of the first track changing device; similarly, the second connecting component in the first track changing device, the third connecting component and the fourth connecting component in the second track changing device, the fifth connecting component and the sixth connecting component in the third track changing device, the seventh connecting component and the eighth connecting component in the fourth track changing device are all provided with vertical and transverse limiting components that play the same role as the first connecting component, that is, when the track parts in different connecting components 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 components, disperses the load-bearing load of the track changing device, thereby achieving more reliable structural safety of the track changing device.

[0074] Further, taking the first track beam being in its own passage as an example, when the first track portion in the first track-changing device is at the lower limit position, it coincides and docks with the track surface of the first track beam, and when the seventh track portion in the fourth track-changing device is at the lower limit position, it coincides and docks with the track surface of the first track beam. At this time, 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, and locks the seventh track portion through the seventh locking device, further ensuring the stability and safety performance of the docking point. After the train passes the first track beam, the first locking device releases the first track surface, and the seventh locking device locks the seventh track portion. The seventh track surface is released; similarly, the second connecting component in the first track changing device, the third connecting component and the fourth connecting component in the second track changing device, the fifth connecting component and the sixth connecting component in the third track changing device, and the eighth connecting component in the fourth track changing device are all provided with locking devices which play the same role as those in the first connecting component and the seventh connecting component, that is, when the track parts in different connecting components are in a state of overlapping and docking with the track surface, the corresponding locking devices lock the corresponding track parts, so as to further ensure the structural safety performance of the docking area. The locking and releasing in the double-track track beam are controlled by the operation management system in the suspended air-rail system.

[0076] External suspension

[0077] Refer to the attached Fig.14, the figure shows a schematic diagram of the structure when the first track beam 1 and the second track beam 2 in the external suspension track are in the passage; at this time, the first connecting member in the first track changing device 7 and the seventh connecting member in the fourth track changing device 10 move downward to the lower limit position under the drive of their respective driving devices, and the first connecting portion in the first connecting member is combined with the web notch of the first track beam, the first track portion in the first connecting member is docked with the running board of the first track beam, the seventh connecting portion in the seventh connecting member is combined with the web notch of the first track beam, and the seventh track portion in the seventh connecting member is docked with the running board of the first track beam, so as to realize the passage of the first track beam itself; the third connecting member in the second track changing device 8 and the fifth connecting member in the third track changing device 9 move downward to the lower limit position under the drive of their respective driving devices, and the third connecting portion in the third connecting member is combined with the web notch of the second track beam. The third connecting member is connected at the notch, the third track portion in the third connecting member is connected to the running board of the first track beam, the fifth connecting portion in the fifth connecting member is connected to the notch of the web of the second track beam, and the fifth track portion in the fifth connecting member is connected to the running board of the second track beam, so as to realize the passage of the second track beam itself; at the same time, the second connecting member, the fourth connecting member, the sixth connecting member, and the eighth connecting member are driven by their respective driving devices to move upward to the upper limit position, and the upward movement to the upper limit position and the downward movement to the lower limit position are synchronous reverse movements. This action is the second action set. When the track needs to be changed at the track fork, the first action set is implemented, that is, the connecting guide track beam, the second action set and the first action set are opposite actions. When the train passes, it is restored to the default state before the implementation of the first action set; the first track changing device and the second track changing device can quickly realize the vehicle track change and double-track vehicle operation, improve the overall operation efficiency, and save track change time.

[0078] Refer to the attached Fig.15, the figure is a schematic structural diagram of the first guide track beam 3 and the third guide track beam 5 in the external suspended track when they are in a passage through the switch device 11, that is, the first track beam 1, the first guide track beam 3, the third guide track beam 5, and the second track beam 2 are in a connected state; at this time, the second connecting member and the sixth connecting member move downward to the lower limit position under the drive of their respective driving devices, the second connecting portion of the second connecting member is combined with the web notch of the first guide track beam, the second track portion of the second connecting member is connected with the first track beam and the walking plate of the first guide track beam, connecting the first track beam and the first guide track beam, the sixth connecting portion of the sixth connecting member is combined with the web notch of the third guide track beam, the sixth track portion of the sixth connecting member is connected with the walking plate of the first track beam and the third guide track beam, connecting the first track beam and the third guide track beam, and the switch device is under the control of the signal. The control drives the transition track beam to rotate, so that the transition track beam rotates until its two ends are respectively connected with the first guide track beam 3 and the third guide track beam 5, so as to realize the connection between the first guide track beam and the third guide track beam, and realize the connection of the first passage. At the same time, the first connecting member and the fifth connecting member move upward to the upper limit position under the drive of the driving device without interfering with the operation of the train. The upward movement to the upper limit position and the downward movement to the lower limit position are synchronous reverse movements. When the track needs to be changed at the track fork, the first action set is implemented to make the first track beam and the second track beam in their own disconnected state, that is, the first action set completes the closure of the straight section of the first track beam and the closure of the straight section of the second track beam, and opens the guide track beam between the first track beam and the second track beam through the corresponding track changing device and the switching device, so as to realize the connection between the guide track beam and the corresponding first track beam and the second track beam, thereby realizing the purpose of changing the track at the fork of the vehicle.
