AI Technical Summary
When existing automated guided vehicles (AGVs) are used on ships, the swaying caused by waves makes them unstable, prone to displacement or overturning, making it difficult to achieve stable material transfer.
A support frame and lifting module are installed on the ship's deck, equipped with lifting and traveling components. After the pallet is lifted to the same height by the lifting module, the pallet is moved to different transfer modules along the docking track by the traveling component. Heavy-duty ball bearings are used to provide support to ensure the stability of the transfer process.
It enables high-precision and high-stability material transfer in a ship swaying environment, avoiding path interference and improving the accuracy and safety of the transfer process.

[0072] Step 4: In the first transfer module 8 or the second transfer module 9, the walking motor 505 in the walking component 5 rotates in the forward direction, and the walking gear 506 meshes with the walking rack 504 to make the walking component 5 move forward along the length of the walking guide rail 503 and reach the docking point with the lifting component 3.
[0073] Step 5: The docking post 501 in the walking assembly 5 matches the docking hook 402 in the pallet assembly 4;
[0074] Step 6: The walking motor 505 in the walking assembly 5 rotates in the opposite direction, and the walking gear 506 meshes with the walking rack 504, causing the entire walking assembly 5 to move backward along the length of the transverse walking guide rail 503, simultaneously pulling the pallet assembly 4 backward until it reaches the starting position of the walking assembly 5. At this time, the pallet assembly 4 is located in the first transfer module 8 or the second transfer module 9.
[0075] When pallet assembly 4 needs to be transferred into the third transfer module 10, the following steps are included:
[0076] Step 1: The entire tray assembly 4 is placed on the lifting assembly 3 inside the lifting module 7;
[0077] Step 2: The lifting motor 301 of the lifting component 3 is started, and the lifting rod 302 drives the lifting platform 303 to the same height as the top surface of the bracket 2;
[0078] Step 3: The vertically oriented removal track 304 of the lifting component 3 connects with the vertically oriented docking track 13 inside the third transfer module 10;
[0079] Step 4: The walking motor 505 in the walking component 5 in the third transfer module 10 rotates in the forward direction, and the walking gear 506 meshes with the walking rack 504, causing the walking component 5 to move forward along the length of the walking guide rail 503 and reach the docking point with the lifting component 3.
[0080] Step 5: The docking post 501 in the walking assembly 5 matches the docking hook 402 in the pallet assembly 4;
[0081] Step 6: The walking motor 505 in the walking assembly 5 rotates in the opposite direction, and the walking gear 506 meshes with the walking rack 504, causing the entire walking assembly 5 to move backward along the length of the vertical walking guide rail 503, and simultaneously pulling the pallet assembly 4 backward until it reaches the starting position of the walking assembly 5. At this time, the pallet assembly 4 is located in the third transfer module 10.
[0082] When pallet assembly 4 needs to be transferred into the fourth transfer module 11 or the fifth transfer module 12, the following steps are included:
[0083] Step 1: The entire tray assembly 4 is placed on the lifting assembly 3 inside the lifting module 7;
[0084] Step 2: The lifting motor 301 of the lifting component 3 is started, and the lifting rod 302 drives the lifting platform 303 to the same height as the top surface of the bracket 2;
[0085] Step 3: The vertically oriented removal track 304 of the lifting component 3 connects with the vertically oriented docking track 13 inside the third transfer module 10;
[0086] Step 4: The walking motor 505 in the walking component 5 in the third transfer module 10 rotates in the forward direction, and the walking gear 506 meshes with the walking rack 504, causing the walking component 5 to move forward along the length of the walking guide rail 503 and reach the docking point with the lifting component 3.
[0087] Step 5: The docking post 501 in the walking assembly 5 matches the docking hook 402 in the pallet assembly 4;
[0088] Step 6: The walking motor 505 in the walking assembly 5 rotates in the opposite direction, and the walking gear 506 meshes with the walking rack 504, causing the entire walking assembly 5 to move backward along the length of the vertical walking guide rail 503, and simultaneously pulling the pallet assembly 4 backward until it reaches the starting position of the walking assembly 5. At this time, the pallet assembly 4 is located in the third transfer module 10.
[0089] Step 7: The walking motor 505 in the walking component 5 in the fourth transfer module 11 or the fifth transfer module 12 rotates in the forward direction. The walking gear 506 meshes with the walking rack 504, causing the walking component 5 to move forward along the length of the walking guide rail 503 and reach the docking point with the third transfer module 10. The third transfer module 10 is in a disengaged state from the pallet component 4.
[0090] Step 8: The docking post 501 in the walking component 5 in the fourth transfer module 11 or the fifth transfer module 12 matches the docking hook 402 on one side of the pallet component 4;

At this time, since the height of the docking track 13 is greater than the walking guide rail 503 of the walking component 5, the walking component 5 in the fourth transfer module 11 or the fifth transfer module 12 can directly pull the pallet component 4 across the walking guide rail 503 in the third transfer module 10 until it returns to the fourth transfer module 11 or the fifth transfer module 12.
[0092] In this embodiment, when multiple pallet components 4 need to be transferred sequentially, the transfer modules can be reasonably allocated. For example, the pallet components 4 are first raised to the same height as the support 2 by the lifting module 7, and then transported sequentially into the fourth transfer module 11 and the fifth transfer module 12 by the third transfer module 10. After they have been transported into the fourth transfer module 11 and the fifth transfer module 12, the subsequent pallet components 4 are then transported into the first transfer module 8, the second transfer module 9, or the third transfer module 10. This working mode can greatly improve the space utilization rate.
[0093] In this invention, the lifting component 3 in the lifting module 7 raises the pallet assembly 4 to the same height as the support 2, and then moves it to the docking point through the walking component 5 in the corresponding transfer module. The docking column 501 matches and engages with the docking hook 402, pulling the pallet assembly 4 back into the corresponding transfer module as a whole. During the movement, the pallet always moves within the removal track 304 and the docking track 13 through the guide component 403. At the same time, since both the removal track 304 and the docking track 13 are U-shaped frames with built-in guide tracks, the guide component 403 always moves along the track during the movement, which is not easily affected by the external environment, and the transfer process has high precision.
