The rail changing mechanism 4 drives the shuttle cars 3 on the rail changing mechanism to change positions on the two groups of ground rails 1 and 2, namely the rail changing mechanism drives the shuttle cars to reciprocate between a first rail changing position connected with the first group of ground rails 1 and a second rail changing position connected with the second group of ground rails 2.

Referring to fig. 1, each of the rail replacing mechanisms 4 includes a base 41, a rail replacing plate 42, a rail replacing motor 43, and the like.

As shown in fig. 1, bases 41 are provided at both ends of the two ground rails 1 and 2, and the bases 41 serve as supports for the rail replacing mechanism 4. A rack 44 is laid on the base 41 and is perpendicular to the ground track. The bottom of the rail changing flat plate 42 is provided with a gear which is meshed with the rack 44.

The outer side end of the rail-changing flat plate 42 is provided with a rail-changing motor 43 for driving the gear to reciprocate along the rack 44. The rail replacing flat plate 42 is provided with a rail replacing rail 45 which has the same width and the same direction as the ground rails 1 and 2, and when the rail replacing flat plate 42 runs to a first rail replacing position, the rail replacing rail 45 is in butt joint with a first group of ground rails 1; when the rail changing plate 42 is moved to the second rail changing position, the rail changing rails 45 are butted against the second group of the ground rails 2. The two ends of the ground tracks 1 and 2 are horizontally spaced from the rail-changing flat plate 42 by 5 mm, and the heights of the ground tracks 1 and 2 are consistent with the height of the rail-changing track 45, so that the flawless butt joint at the same height is ensured. Alternatively, the support pads may be padded on the bottom of the ground tracks 1 and 2 to achieve the same purpose. A polyurethane buffer 47 is provided at the outermost end of the track-changing rail 45, and this polyurethane buffer 47 prevents the shuttle 3 from moving forward again and buffers it. As shown in fig. 1, a charging pile 46 is disposed on the rail-changing plate 42, and the charging pile 46 is connected to an external power source through a charging wire. When the shuttle car 3 runs onto the rail changing plate 42 and is docked with the charging pile 46, the charging pile 46 charges the shuttle car 3.
