As shown in fig. 2, the carrying mechanism 13 includes the overlapped guide rail 3, and the overlapped guide rail 3 adopts a structure of overlapping two cavities on a single guide rail to realize the overlapping of the strokes. The upper cavity of the overlapped guide rail 3 is connected with the door leaf 4 of the door leaf mechanism 25 in a sliding manner, the lower cavity is internally provided with the bearing wheel carrier assembly 1, the bottom of the bearing wheel carrier assembly 1 is fixed on the bearing welding support 2, and the bearing welding support 2 is positioned below the overlapped guide rail 3. By nesting the load bearing wheel carriage assembly 1 within the overlapping guide track 3, load bearing and guidance is provided for the overlapping guide track 3. A first buffer plate 7 and a second buffer plate 10 are mounted at the top of the overlapped guide rail 3, wherein the first buffer plate 7 is positioned at the end part of the overlapped guide rail 3, and a second buffer head 12 is fixed on the second buffer plate 10; the third buffer plate 8 and the fourth buffer plate 14 are respectively installed at both ends of the bottom.
As shown in fig. 2 and 3, the door leaf mechanism 25 includes a door leaf 4, a first wheel frame assembly 5 is installed on one side of the door leaf 4, and a second wheel frame assembly 11 is installed on the other side of the door leaf 4, wherein a first buffer head 6 is fixed on the first wheel frame assembly 5. And a third buffer head 9 and a fourth buffer head 15 are respectively arranged at two ends of the bearing welding bracket 2. As shown in fig. 4, a transmission mechanism 18 is mounted on the bottom plate of the load-bearing welding bracket 2, the transmission mechanism 18 includes a motor 23, and the motor 23 is fixed on the load-bearing welding bracket 2.
