[0002] Many track-moving equipment (such as stackers, AGV robots, etc.) are double-track track-changing devices. The turnout is an important component of the track-switching stacker system. The stacker can switch tracks freely through the turnout, making the track scalable. On the premise of meeting the frequency of in-and-out storage, the number of stackers can be reduced, the cost of the vertical warehouse can be greatly reduced, and the degree of automation and flexibility are higher. With the development of society, people have higher and higher requirements for the use of vertical warehouses, the storage capacity is getting larger and larger, and the control of the cost of vertical warehouses is becoming more and more stringent.
