Example (b):
the embodiment provides a displacement amplification mechanism 140, an empty rail turnout 010 and an empty rail track; the air-rail track includes a main road straight rail 310, a branch road straight rail 320, a branch road diverging rail 330, and the air-rail turnout 010. Specifically, the main straight-line rail 310, the branch straight-line rail 320 and the branch forked rail 330 are all erected in the air by a support beam (not shown) on the ground, wherein the branch straight-line rail 320 and the main straight-line rail 310 are arranged in a collinear manner, and the branch forked rail 330 and the main straight-line rail 310 are arranged at an obtuse angle. The air-railway turnout 010 is provided at the intersection of the main road linear rail 310, the branch road linear rail 320, and the branch road diverging rail 330, and is used for switching the traveling route of the air-railway vehicle. The air railway switch 010 includes a switch body 100 and an air railway moving rail 200, and the air railway moving rail 200 moves in the lateral direction of the switch body 100, thereby achieving communication between the main straight rail 310 and the branch straight rail 320 or the branch diverging rail 330.
The empty railway switch 010 comprises an empty railway moving rail 200 and a switch body 100, wherein the empty railway moving rail 200 is in sliding fit with the switch body 100 and can slide along the transverse direction of the switch body 100; thereby switching between a linear rail position and a curved rail position. When the air-rail moving rail 200 moves to the curved rail position (figure), the air-rail switch 010 forms a linear rail that communicates the main linear rail 310 with the branch linear rail 320. When the air-rail moving rail 200 moves to the linear rail position (figure), the air-rail turnout 010 forms a curved rail; the curvilinear track communicates the main straight track 310 with the branch diverging track 330.
The air rail moving rail 200 includes a translation device and a moving rail body 220, wherein the translation device is connected to the upper portion of the moving rail body 220 and is in sliding fit with the switch body 100 in the transverse direction.
