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 main track beam is in a self-communicating state, that is, when the first communicating member descends to a lower limit point and is in butt joint with the notch on the corresponding main track beam, and when a bogie of a train passes through the first track part of the first communicating member, the first main track part transmits pressure to the first connecting part through a vertical limiting member (not shown) between the first connecting part and the first connecting part, and because the width of the first connecting part is greater than that of the first track part, the pressure on the first connecting part can transmit force to the first main track through the connecting part and the 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 main line track beam main body through a transverse limiting component (not shown) arranged on the main line track beam; in the invention, the load pressure borne by the first track transfer device in a working state can be transmitted to the main line 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 is also provided with a vertical member and a transverse member which play the same role as 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 load force from the train bogie is transmitted to the rail beam main body through the limiting members by the rail parts and the connecting parts, the load bearing of the rail transfer device is dispersed, and therefore the more reliable structural safety of the rail transfer device is realized.

Further, when the first track part is positioned at the lower limit point and is superposed and butted with the track surface of the main line track beam, the main line track beam is in a passage state, and a train can pass along the main line track beam; at the moment, the main line track locks the first track part through the 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 main line track, the first locking device releases the main line track surface; similarly, the second communicating member in the first track-changing device is also provided with a locking device which has the same function as that of the first communicating member, namely when the track parts in different communicating members are in a state of being overlapped and butted with the track surface, the corresponding locking device locks the corresponding track parts, so that the structural safety performance of a butted area is further guaranteed; the first action set, the second action set, the locking and the releasing of the multi-line track beam are all controlled by an operation management system in the suspension type air-rail system.

Furthermore, the third orbital transfer device realizes the rotation of the third orbital transfer device through the matching of two arc-shaped tooth tracks arranged on the third orbital transfer device and a gear of the driving device; the connecting member is rotatably connected with a track top plate arranged above a cross area of the forked track beam, so that the third track transfer device is borne and rotated; the connecting component can be a pivoting support, so that the structural strength of the third rail transfer device and the bearing of the train are guaranteed.
