[0029] An adjusting and switching mechanism is arranged between each group of reversing tracks 7, and is used to adjust the lateral or longitudinal position of the reversing tracks 7. The adjusting and switching mechanism comprises a rotating disc 5, a connecting frame 6, a connecting shaft 11, a driven gear 12, a driving gear 14, and a speed reducer motor 15. A rotating disc 5 is rotatably arranged inside the channel 4 of each support beam 1. The top of the rotating disc 5 is provided with a connecting frame 6, and the top side of the connecting frame 6 is fixed with a reversing track 7. The speed reducer motor 15 is fixedly connected to the middle of the bottom of the support beam 1. The output end of the speed reducer motor 15 extends into the fixed frame 13 and is connected to the driving gear 14. The inner sides of both ends of the fixed frame 13 are rotatably connected to a connecting shaft 11 through bearings, close to the lower side of the corresponding channel 4. The top end of the connecting shaft 11 is connected to the rotating disc 5, and the bottom end of the connecting shaft 11 is provided with a driven gear 12 that meshes with the driving gear 14. A cavity is formed in the side wall of the driving gear 14, and the transmission ratio of the driven gear 12 to the driving gear 14 is 1:3.
