With the lifting transmission of the lifting screw 44, the top platform 12 can also move up and down linearly. At the same time, the top platform 12 can also rotate with the moving roller 47. In actual operation, as in the embodiment, Figure 5 As shown, the RGV robot has its own system that can communicate with other on-board systems in real time, automatically take out the battery pack from the bottom of the heavy truck, and cooperate with other visual systems to record the deflection angle, correct the battery pack on the platform before sending it into the three-dimensional battery warehouse, take out the fully charged battery pack after sending the battery pack into the three-dimensional battery warehouse, and rotate it to the same angle as the old battery pack, and automatically transport the battery pack to the bottom bracket of the heavy truck. Compared with traditional manual battery replacement operations, this application can greatly reduce the tediousness of battery replacement operations in actual use, and replace heavy-duty truck batteries in a fully automated manner, which is more efficient and safer.

[0027] Furthermore, the RGV robot is an important part of the battery replacement on the heavy truck side. In the actual battery replacement operation, the weight of a single battery pack reaches 1200KG. This solution can ensure that the battery pack replacement process can be completely unmanned, and the whole process is smooth, accurate and fast;

[0028] Furthermore, in addition to the excellent hardware equipment, this solution is equipped with an RGV robot system that can communicate and connect with the three-dimensional battery warehouse and heavy trucks in real time.

[0029] It should be noted that the power connection method of the RGV robot system and the TGV robot mentioned in this application is the existing technology, and the control system can be implemented by programming by technical personnel in this field. It belongs to the common knowledge in this field. It is only used without modification, so the control method and circuit connection will not be described in detail.

[0031] In this embodiment, in actual use, by setting up the left and right moving servo motor 41 and the rotation control of the transmission gear 42, when the transmission gear 42 is rotating, the transmission gear 42 and the teeth on the left and right moving rails 21 are engaged with each other, so that the moving platform 11 can move in a straight line within the travel range of the left and right moving rails 21.

[0032] Specifically, refer to Figure 1-4Two left and right movable tracks 21 are arranged in parallel on the upper end surface of the fixed platform 23 , and four sets of rotating disks 43 are arranged in a rectangular shape on the lower end surface of the movable platform 11 . The rotating disks 43 slide outside the left and right movable tracks 21 and abut against the outer walls of the left and right movable tracks 21 .
