[0002] RGV, also known as rail shuttle, can be used in various warehouses with high-density storage. The trolley track can be laid at any length as needed, thereby increasing the storage capacity of the entire three-dimensional warehouse. RGV runs fast, does not require forklifts or manual operation, is highly safe, and all actions are controlled and implemented by electricity and software, which reduces the workload of warehouse managers and greatly improves labor productivity. Therefore, the use of RGV makes the intelligent logistics system more flexible and convenient.

If a special workstation requires the goods to be rotated 180 degrees for operation, it is difficult to achieve. Only a 180-degree rotating line can be added for docking. This not only takes up space and affects the overall layout of the project, but also increases the cycle time of this area. Utility Model Content

[0036] Working principle:

[0037] Travel of the rotating mobile device: start the travel motor 3, and the travel motor 3 drives the driving wheel 21 in the wheel beam assembly 2 to rotate through the couplings 4 on both sides, and the driven wheel 22 rotates accordingly. The side guide wheels 25 are used to straighten the wheel beam 23 to prevent the driving wheel 21 and the driven wheel 22 from deviating from the track, thereby driving the wheel beam assembly 2 to drive the rotating mobile device to move on the ground rail 111; during the movement, the collector arm 10 slides in contact with the power rail 112 through the collector brush, and directly transmits the electric energy to the travel motor 3, the electric box 78 and the brake resistor box 81, thereby realizing the mobile power supply of the system; the cleaning block 24 at the end of the wheel beam 23 is used to clean up the debris on the ground rail 111 to prevent damage to the driving wheel 21, the driven wheel 22 and the wheel beam 23; the anti-collision radar 9 is used to maintain a safe distance, and emergency braking is performed when it senses a person or object in front.

[0038] Rotation of the rotating moving device: When the material frame needs to be reversed, the rotating driving member 72 is started, and the rotating driving member 72 drives the rotating driving wheel 73 to drive the rotating driven wheel 74 to rotate on the circular guide rail 5. The rotating driven wheel 74 and the rotating driving wheel 73 drive the conveying beam 71 to rotate, and the conveying beam 71 rotates relative to the fixed support frame 1 through the rotating connecting plate 77 and the rotating supporting plate 83. When the photoelectric detection member 75 detects the deceleration sensing sheet 84, the photoelectric detection member 75 controls the reduction motor 79 to start, and the reduction motor 79 controls the rotating driving wheel 73 to decelerate until it stops through the transmission member. After the position sensing sheet 76 rotates to the right position, the detection switch 85 detects that the position sensing sheet 76 controls the rotating driving member 72 to stop, so that the conveying beam 71 stops; when the conveying beam 71 is in place but still does not stop, the conveying beam 71 contacts the limit position blocking member 6, and the limit position blocking member 6 is used to buffer and stop the conveying beam 71, thereby ensuring that the rotating moving device stops at the required position, which is convenient for the docking of the material frame.
