Description
Technical Field
[0001] This invention relates to the field of transfer equipment technology, and in particular to a transfer device for large, heavy-duty goods on ships. Background Technology
[0002] Ships frequently need to transfer production and living supplies to corresponding warehouses during operation. Although automated warehousing and transfer technology on land is very mature, there are still many problems in achieving automated transfer on ships. The most prominent problem is how to ensure that automated material transfer equipment carrying heavy loads can stably and safely travel along the prescribed path to complete the transfer task when the ship is rolling.
[0003] Existing automated guided vehicles (AGVs) for land transport cannot be used directly on ships that are rocking, because the swaying caused by waves will seriously interfere with the AGV's movement path, causing displacement, overturning and other phenomena.
[0004] Current solutions for transferring large, heavy cargo on ships typically involve workers driving forklifts and other freight equipment. The pallets currently used are fixed, ordinary pallets that lack automated operation capabilities and anti-tipping locking features. Summary of the Invention
[0005] In response to the shortcomings of the existing production technology, the applicant provides a transfer device for large, heavy-duty materials on ships, which enables the transfer pallet to move along the transfer direction while simultaneously entering a locking state, making it suitable for shipboard conditions involving turbulence.

The bottom of the transfer pallet body, at the contact end with the transfer pallet guide assembly, is provided with a longitudinal locking assembly (installed vertically) and a transverse locking assembly (installed laterally). When the transfer pallet is pulled longitudinally by the transfer trolley, the transfer trolley causes the longitudinal unlocking assembly to rotate, thereby unlocking the longitudinal locking assembly.

[0049] The first longitudinal unlocking component 302, the second longitudinal unlocking component 312, and the transverse unlocking component 307 have the same structure. The first longitudinal unlocking component 302 has the following structure: it includes a pressure rod 30201, which is connected to a drive shaft 30204.

[0051] In this embodiment, the structure of the transfer trolley 4 is as follows: it includes a docking post 401, which engages with the hook 329 of the transfer tray 3. One end of the docking post 401 is connected to the output end of the docking motor 402, and the other end of the docking post 401 is directly opposite the unlocking component corresponding to the running direction.

[0055] like Figure 6 As shown in this embodiment, the working method of the present invention in actual operation is as follows:
[0056] The transfer pallet 3 needs to move forward longitudinally. The transfer trolley 4 cooperates with the hook 329 at the top of the transfer pallet 3 in the longitudinal direction. The docking post 401 of the transfer trolley 4 engages with the hook 329 at the top. At this time, the other end of the docking post 401 is directly facing the external pressure bar of the first longitudinal unlocking component 302.
[0057] When the transfer trolley 4 needs to pull the transfer tray 3, the docking column 401 of the transfer trolley 4 is driven by the docking motor 402, causing the external pressure rod of the first longitudinal unlocking component 302 to rotate. The rotation of the external pressure rod will drive the rotating shaft of the first longitudinal unlocking component 302 to rotate synchronously. At this time, the end bevel teeth of the first longitudinal unlocking component 302 mesh with the first unlocking gear 303 and rotate. When the first unlocking gear 303 rotates, it will drive the first connecting rod 304, the second connecting rod 305 and the third connecting rod 306 to move synchronously. At this time, the bottom locking pins of the first guide column 313, the second guide column 315, the third guide column 317 and the fourth guide column 319 are all driven to retract inward by the rocker arm that rotates synchronously with the connecting rod, and the longitudinal lock is released. The transfer trolley 4 pulls the transfer tray 3 to move forward longitudinally. At this time, the fifth guide column 321, the sixth guide column 323, the seventh guide column 325 and the eighth guide column 327 cooperate with the traveling track 502 in the transfer tray guide component 5 to play a guiding and limiting role.
[0058] Example 2:
[0059] In this embodiment, the transfer tray 3 needs to move backward in the longitudinal direction. The transfer trolley 4 cooperates with the hook 329 at the bottom of the transfer tray 3 in the longitudinal direction. The docking post 401 of the transfer trolley 4 is engaged with the hook 329 at the bottom. At this time, the other end of the docking post 401 is directly facing the external pressure bar of the second longitudinal unlocking component 312.
[0060] When the transfer trolley 4 needs to pull the transfer tray 3, the docking column 401 of the transfer trolley 4 is driven by the docking motor 402, causing the external pressure rod of the second longitudinal unlocking component 312 to rotate. The rotation of the external pressure rod will drive the rotating shaft of the second longitudinal unlocking component 312 to rotate synchronously. At this time, the end bevel tooth of the second longitudinal unlocking component 312 meshes with the third unlocking gear 330 and rotates. When the third unlocking gear 330 rotates, it will drive the third connecting rod 306, the second connecting rod 305 and the first connecting rod 304 to move synchronously. At this time, the bottom locking pins of the first guide column 313, the second guide column 315, the third guide column 317 and the fourth guide column 319 are all driven to retract inward by the rocker arm that rotates synchronously with the connecting rod, and the longitudinal lock is released. The transfer trolley 4 pulls the transfer tray 3 to move backward in the longitudinal direction. At this time, the fifth guide column 321, the sixth guide column 323, the seventh guide column 325 and the eighth guide column 327 cooperate with the traveling track 502 in the transfer tray guide component 5 to play a guiding and limiting role.
[0061] Example 3:
[0062] In this embodiment, the transfer tray 3 needs to move laterally. The transfer trolley 4 cooperates with the hook 329 in the lateral direction of the transfer tray 3. The docking post 401 of the transfer trolley 4 engages with the hook 329 on the side. The other end of the docking post 401 is directly opposite the external pressure bar of the lateral unlocking component 307.
[0063] When the transfer trolley 4 needs to pull the transfer tray 3 laterally, the docking column 401 of the transfer trolley 4 is driven by the docking motor 402, causing the external pressure rod of the lateral unlocking component 307 to rotate. The external pressure rod of the lateral unlocking component 307 will drive the rotating shaft of the lateral unlocking component 307 to rotate synchronously. At this time, the end bevel tooth of the lateral unlocking component 307 meshes with the second unlocking gear 308 and rotates. When the second unlocking gear 308 rotates, it will drive the fifth guide column 321, the sixth guide column 323, the seventh guide column 325 and the eighth guide column 327 to move synchronously. At this time, the bottom locking pins of the fifth guide column 321, the sixth guide column 323, the seventh guide column 325 and the eighth guide column 327 are all driven to retract inward by the rocker arm that rotates synchronously with the connecting rod. The lateral lock is released, and the transfer trolley 4 pulls the transfer tray 3 to move laterally. At this time, the first guide column 313, the second guide column 315, the third guide column 317 and the fourth guide column 319 cooperate with the traveling track 502 in the transfer tray guide component 5 to play a guiding and limiting role.
[0064] The present invention has a reasonable structure and is easy to operate. By moving the transfer pallet 3 through the transfer trolley 4 in the translational direction, the docking column 401 of the transfer trolley 4 is driven by the docking motor 402, which causes the unlocking component to cooperate with the connecting rod to unlock the locking component. Then the transfer pallet 3 moves horizontally within the transfer pallet guide component 5 following the transfer trolley 4. After the transfer pallet 3 is disengaged from the transfer trolley 4, the locking pin in the locking component moves down with the arc of the lifting groove, so that the locking pin abuts against the traveling track 502, achieving the locking effect.
[0065] The above description is an explanation of the present invention and not a limitation thereof. The scope of the present invention is defined by the claims. Within the scope of protection of the present invention, any form of modification may be made.

The structure of the second guiding column (315) is as follows: It includes a guiding lifting groove (31502). The guiding lifting groove (31502) rotates in the horizontal direction and is in a "︶" shape. A stud without a head (31501) is arranged in the guiding lifting groove (31502). The bottom of the headless stud (31501) is connected to a sliding locking pin (31504). The headless stud (31501) moves up and down in the groove as the guide lifting groove (31502) rotates, and simultaneously drives the sliding locking pin (31504) to extend and retract along the length of the hollow guide shaft (31503). When the transfer pallet (3) is pulled forward longitudinally by the transfer trolley (4), the transfer trolley (4) drives the longitudinal unlocking component to rotate, thereby unlocking the longitudinal locking component; the transfer trolley (4) cooperates with the hook (329) at the top of the transfer pallet (3) in the longitudinal direction, and the docking post (401) of the transfer trolley (4) engages with the hook (329) at the top. At this time, the other end of the docking post (401) is directly facing the external pressure bar of the first longitudinal unlocking component (302); When the transfer trolley (4) needs to pull the transfer tray (3), the docking column (401) of the transfer trolley (4) is driven by the docking motor (402) to make the external pressure rod of the first longitudinal unlocking component (302) rotate. The rotation of the external pressure rod will drive the rotating shaft of the first longitudinal unlocking component (302) to rotate synchronously. At this time, the end bevel tooth of the first longitudinal unlocking component (302) meshes with the first unlocking gear (303) and rotates. When the first unlocking gear (303) rotates, it will drive the first connecting rod (304), the second connecting rod (305) and the third connecting rod (306) to move synchronously. At this time, the bottom locking pins of the first guide column (313), the second guide column (315), the third guide column (317) and the fourth guide column (319) are all driven to retract inward by the rocker arm that rotates synchronously with the connecting rod, and the longitudinal lock is released. When the transfer pallet (3) is pulled by the transfer trolley (4) to move backward in the longitudinal direction, the transfer trolley (4) cooperates with the hook (329) at the bottom of the transfer pallet (3) in the longitudinal direction, and the docking post (401) of the transfer trolley (4) engages with the hook (329) at the bottom. At this time, the other end of the docking post (401) is directly facing the external pressure bar of the second longitudinal unlocking component (312). When the transfer trolley (4) needs to pull the transfer tray (3), the docking column (401) of the transfer trolley (4) is driven by the docking motor (402) to make the external pressure rod of the second longitudinal unlocking component (312) rotate. The rotation of the external pressure rod will drive the rotating shaft of the second longitudinal unlocking component (312) to rotate synchronously. At this time, the end bevel tooth of the second longitudinal unlocking component (312) meshes with the third unlocking gear (330) and rotates. When the third unlocking gear (330) rotates, it will drive the third connecting rod (306), the second connecting rod (305) and the first connecting rod (304) to move synchronously. At this time, the bottom locking pins of the first guide column (313), the second guide column (315), the third guide column (317) and the fourth guide column (319) are all driven to retract inward by the rocker arm that rotates synchronously with the connecting rod, and the longitudinal lock is released. When the transfer pallet (3) is pulled by the transfer trolley (4) to move laterally, the transfer trolley (4) drives the lateral unlocking component (307) to rotate, thereby unlocking the lateral locking component; the transfer trolley (4) cooperates with the hook (329) in the lateral direction of the transfer pallet (3), and the docking post (401) of the transfer trolley (4) engages with the hook (329) on the side. At this time, the other end of the docking post (401) is directly facing the external pressure bar of the lateral unlocking component (307); When the transfer trolley (4) needs to pull the transfer tray (3) to move laterally, the docking column (401) of the transfer trolley (4) is driven by the docking motor (402) to make the external pressure rod of the lateral unlocking component (307) rotate. The external pressure rod of the lateral unlocking component (307) will drive the rotating shaft of the lateral unlocking component (307) to rotate synchronously. At this time, the bevel teeth at the end of the lateral unlocking component (307) mesh with the second unlocking gear (308) and rotate. When the second unlocking gear (308) rotates, it will drive the fifth guide column (321), the sixth guide column (323), the seventh guide column (325) and the eighth guide column (327) to move synchronously. At this time, the bottom locking pins of the fifth guide column (321), the sixth guide column (323), the seventh guide column (325) and the eighth guide column (327) are all driven to retract inward by the rocker arm that rotates synchronously with the connecting rod. The lateral lock is released, and the transfer trolley (4) pulls the transfer tray (3) to move laterally.
