DETAILED DESCRIPTION

[0018] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0019] See Figure 1-3 A support base 2 is provided on the top of the rail trolley body 1, and a support platform 22 is provided on the top of the support base 2. Roller conveyor assemblies 21 are provided on both sides of the support platform 22. The tray 5 is moved on the support platform 22 by the roller conveyor assemblies 21. It is worth noting that the specific structure and working method of the roller conveyor assembly 21 are all existing technologies and therefore will not be described in detail.

[0020] Baffle slots 23 are provided on both sides of the support platform 22 and are perpendicular to the roller conveyor assembly 21. A movable column 3 is vertically and movably disposed within the baffle slots 23, and a plurality of baffles 32 are fixedly mounted on the movable column 3. A middle slot 24 is provided in the middle of the support platform 22. Two middle seats 35 are movably disposed within the middle slot 24 and are fixedly connected to the movable column 3. Multiple lower magnetic columns 36 are fixedly mounted on the tops of the middle seats 35.

[0021] Among them, the side grooves 25 are all opened on the supporting platform 22 and are located on both sides of the baffle groove 23. An adjustment plate 4 is arranged in the baffle groove 23 for horizontal movement. A movable part 41 is fixedly arranged on one side of the adjustment plate 4, and sub-slopes 42 are arranged on both sides of the movable part 41.

[0022] See Figure 4-9The top of the baffle groove 23 is fixed with multiple anti-dropping members 231, and the movable column 3 is adapted to have an anti-dropping groove 31 corresponding to the anti-dropping members 231. The bottom plate of the baffle groove 23 located below the anti-dropping members 231 is fixed with a guide column downward, and the movable column 3 is guided by the guide column to improve the stability of the movable column 3 during movement.

[0023] Among them, a plurality of baffles 32 are fixedly set on the top of the movable column 3. Through the setting of the baffles 32, the positioning of the two sides of the pallet 5 can be achieved to achieve the positioning of the pallet 5, thereby preventing the pallet 5 from being displaced during the movement of the rail trolley body 1.

[0024] Among them, a middle groove 24 is opened in the middle of the support platform 22, and two middle seats 35 are vertically movable in the middle groove 24. The middle seats 35 on each side are fixedly connected to the movable column 3 through the connecting column 34, and the corresponding connecting columns 34 in the support platform 22 are adapted to be opened with a connecting cavity 234, so that the movable column 3 and the middle seat 35 can move synchronously.

[0025] A vertical guide column is fixedly provided in the communication cavity 234 , and the connecting column 34 is guided to move by the guide column to improve the stability of the connecting column 34 and the middle seat 35 during the movement.

[0026] The bottom of the baffle groove 23 is provided with a plurality of lower spring cavities 232, each of which is upwardly mounted with a lower spring 233. The other end of each lower spring 233 is connected to the movable column 3. The movable column 3 can be pushed upward by the elastic force of the lower spring 233 on the movable column 3.

[0027] The inner wall of the side groove 25 defines multiple side spring cavities 251, each containing a side spring 252. The other ends of the side springs 252 are connected to the adjustment plate 4. The side springs 252 push against the adjustment plate 4, ensuring that the locking column 43 is securely secured within the locking cavity 33, thereby ensuring stable fixation of the movable column 3 and the baffle 32. It is worth noting that both the lower spring 233 and the side springs 252 are conventionally strong, shock-absorbing springs to ensure stability in extreme vibration environments. This is conventional technology and will not be further elaborated.

[0028] The side grooves 25 are connected to the baffle grooves 23, and the adjustment plates 4 are adapted to be movable within the side grooves 25. A plurality of latching posts 43 are fixedly mounted on the adjustment plate 4, and each latching post 43 is adapted to be fitted into the latching cavity 33. The latching cavities 33 on the baffle 32 are respectively arranged as an upper latching cavity 33 and a lower latching cavity 33. When the latching posts 43 are latched in the lower latching cavity 33, the movable post 3 and the baffle 32 are both stably fixed above. When the latching posts 43 are latched in the upper latching cavity 33, the movable post 3 and the baffle 32 are both stably fixed within the baffle groove 23.

[0029] See Figure 10-18 An outer base 51 is fixedly provided at the corners of the bottom of the tray 5, a middle plate 53 is fixedly provided in the middle of the bottom of the tray 5, and side bases 52 are fixedly provided on both sides of the middle plate 53 at the bottom of the tray 5. Both ends of the side base 52 and the bottom of the middle plate 53 are inlaid with magnetic parts 54, and the top of the baffle 32 is set to a magnetic material that is compatible with and repels the magnetic parts 54.

[0030] The side base 52 has upper female bevels 521 and locking grooves 522 formed on both ends of the side base 52, from the outside inward. The upper female bevels 521 and locking grooves 522 are adapted to the sub-bevels 42 on the movable member 41. The adaptation between the upper female bevels 521 and the sub-bevels 42 allows the movable member 41 to be pushed outward during movement of the side base 52, thereby releasing the mutual engagement between the locking column 43 and the locking cavity 33.

[0031] The side bases 52 each have a central movable cavity 523, with guide plates 525 fixedly positioned within each cavity. Both ends of the movable plate 6 pass through the movable cavity 523, and the movable plate 6 has corresponding guide cavities corresponding to the guide plates 525. Because the guide plates 525 are relatively high, the movable plate 6 will not fall out of the guide plates 525 even when it moves upward into the top cavity 524.

[0032] In addition, an outer plate is provided on the outer side of the side base 52 to prevent the pushed-out movable member 41 from automatically resetting when the side base 52 moves.

[0033] The side base 52 has a top cavity 524 above the movable cavity 523, and a cavity is formed on both sides of the movable cavity 523. Elastic cords 526 are installed in each cavity, and the other ends of the elastic cords 526 are connected to the movable plate 6. The elastic cords 526 on both sides allow the movable plate 6 to automatically return to the middle position when it is not moving due to the elastic force of the elastic cords 526.

[0034] The bottom of the movable plate 6 is fixedly provided with a plurality of upper magnets 62 and upper magnetic columns 63. The upper magnets 62 are adapted to attract the lower magnets 26. The upper magnets 62 and lower magnets 26 are adapted to attract each other, so that the movable plate 6 can be sucked downward, and the movable plate 6 can be moved downward from the top cavity 524 to the movable cavity 523.

[0035] A lower magnetic ring 65 is fixedly provided on the top of the movable plate 6, and an upper magnetic ring 531 is fixedly provided on the bottom of the middle plate 53 to be adapted to attract the lower magnetic ring 65. The magnetic force between the lower magnetic ring 65 and the upper magnetic ring 531 can be used to attract the movable plate 6 upward, so that the movable plate 6 is attracted from the movable cavity 523 to the top cavity 524.

[0036] It is worth noting that the magnetic force between the upper magnet 62 and the lower magnet 26 is greater than the magnetic force between the lower magnetic ring 65 and the upper magnetic ring 531 , which enables the movable plate 6 to move downward preferentially through the magnetic force between the upper magnet 62 and the lower magnet 26 .

[0037] Among them, the upper magnetic column 63 is adapted to repel each other with the lower magnetic column 36, so that the middle seat 35 can be pushed downward by the repulsive magnetic force between the upper magnetic column 63 and the lower magnetic column 36. At this time, the movable column 3 can overcome the elastic force of the lower spring 233 and move downward due to the magnetic force.

[0038] The movable plate 6 is fixedly provided with side plates 61 on both sides, which mate with the roller conveyor assembly 21. Fixed plates 64 are fixedly provided on both sides of the bottom of the movable plate 6. Lower female slopes 641 are provided on both sides of the fixed plates 64, which mate with the movable member 41. The side plates 61 enable the roller conveyor assembly 21 to convey the movement of the movable plate 6. The fit between the lower female slopes 641 and the sub-slopes 42 allows the movable member 41 to be pushed outward during the movement of the movable plate 6.

[0039] In this embodiment, workbenches can be installed on both sides of the track of the rail-mounted trolley body 1, and workbench roller conveyors can be installed on the workbenches. It is only necessary to ensure that the workbench roller conveyors are properly connected to the roller conveyor assembly 21 on the rail-mounted trolley body 1. In this way, when the rail-mounted trolley body 1 moves to one side of the workbench, the workbench roller conveyors on the workbench can transfer the pallet 5 to the roller conveyor assembly 21 on the rail-mounted trolley body 1, thereby achieving the transfer of the pallet 5. It is worth noting that this is existing technology and therefore will not be described in detail.

[0040] Furthermore, the height of the roller conveyor assembly 21 is slightly higher than that of the support platform 22. This ensures that when the pallet 5 is conveyed, only the outer base 51 of the pallet 5 contacts the roller conveyor assembly 21, while the side bases 52 and the middle plate 53 of the pallet 5 do not contact the support platform 22. This reduces friction between the pallet 5 and the support platform 22 during movement. Furthermore, this ensures that when the movable plate 6 is positioned downward, the fixed plate 64 at the bottom of the movable plate 6 can move laterally below the side bases 52 and the middle plate 53.

[0041] In the first embodiment, workbenches are provided on both the left and right sides of the track of the rail trolley body 1. The pallet 5 is loaded from the workbench on the right side to the support seat 2 on the rail trolley body 1, and then the pallet 5 is transferred through the rail trolley body 1 and unloaded from the workbench on the left side.

[0042] When the right workbench is loading the pallet 5, the pallet 5 is conveyed to the roller conveyor assembly 21 on the support base 2 via the workbench roller conveyor. As the pallet 5 moves, the side bases 52 on both sides of the pallet 5 move synchronously until the upper female inclined surface 521 on the side base 52 contacts the sub-inclined surface 42 on the right movable member 41. The movement of the side base 52 pushes the movable member 41 outward, thereby driving the synchronous movement of the adjustment plate 4 and the clamping column 43.

[0043] At this time, the locking between the right latch 43 and the latch cavity 33 is released, and the lower spring 233 at the bottom of the movable column 3 automatically extends upward by elastic force, thereby partially pushing the movable column 3 and the baffle 32 upward. However, since the side base 52 at the bottom of the tray 5 is located above the right baffle 32, the right baffle 32 can only move up a small amount and cannot move up completely.

[0044] As the tray 5 and the side base 52 continue to move, the upper female inclined surface 521 on the side base 52 can also push the left movable member 41 outward, thereby releasing the mutual engagement between the left locking column 43 and the locking cavity 33. At this time, since there is no obstruction from the side base 52 above the left movable column 3 and the baffle 32, the left movable column 3 and the baffle 32 can automatically move up to the highest position due to the elastic force of the lower spring 233.

[0045] The tray 5 then continues to move until it contacts the baffle 32 protruding from the left side, at which point the tray 5 is completely moved onto the support base 2. At this point, the locking grooves 522 on the side base 52 are aligned with the movable member 41, and the side base 52 is no longer above the baffle 32 on the right side. At this point, the right movable column 3 and baffle 32 can also automatically move up to the top due to the elastic force of the lower spring 233.

[0046] When the movable columns 3 and baffles 32 on both sides have reached their highest positions, the locking cavities 33 at the bottom of the baffles 32 align with the locking columns 43. The adjustment plate 4 is then automatically reset by the elastic force of the side springs 252, driving the locking columns 43 to move synchronously and lock into the locking cavities 33 at the bottom of the baffles 32, thereby securing the movable columns 3 and baffles 32 at a high position. Furthermore, the movable members 41 are now locked in the locking grooves 522, allowing the baffles 32 on both sides to position the pallet 5, ensuring its stability during transport.

[0047] As the movable column 3 moves upward, the middle seat 35 also moves upward, driving the lower magnetic column 36 to move upward. When the tray 5 is positioned, the upper magnet 62 at the bottom of the movable plate 6 and the lower magnet 26 on the support platform 22 are adapted to attract each other, thereby magnetically attracting the movable plate 6 from the top cavity 524 to the movable cavity 523.

[0048] Furthermore, in the process of unloading the pallet 5 to the left workbench, the movable plate 6 moves down into the movable cavity 523 due to the magnetic force between the upper magnet 62 and the lower magnet 26. Therefore, at this time, the side plates 61 on both sides of the movable plate 6 move down to contact the roller conveying assembly 21.

[0049] Then, it is only necessary to control the roller conveying assembly 21 to transfer the side plate 61 to the left. At this time, the tray 5 is blocked by the baffles 32 on both sides and cannot move. Therefore, the roller conveying assembly 21 under the outer base 51 can only idle, and the side plate 61 can move to the left.

[0050] In this way, the side plate 61 can drive the fixed plate 64 and the lower female inclined surface 641 to move downward synchronously. In this way, the left movable member 41 can be pushed outward again through the adaptation between the lower female inclined surface 641 and the sub-inclined surface 42, thereby releasing the mutual engagement between the left locking column 43 and the locking cavity 33. At this time, the upper magnetic column 63 at the bottom of the movable plate 6 has moved to the top of the left middle seat 35 and is adapted and aligned with the lower magnetic column 36. In this way, the repulsive magnetic force between the upper magnetic column 63 and the lower magnetic column 36 can push the left middle seat 35 downward. At this time, the movable column 3 can overcome the elastic force of the lower spring 233 due to the magnetic force and move downward.

[0051] When the movable post 3 moves to the bottom, the locking cavity 33 on the upper side of the baffle 32 is aligned with the locking post 43 again. At this time, it is only necessary to control the roller conveyor assembly 21 to transfer the side plate 61 to the right. At this time, the lower female inclined surface 641 on the fixed plate 64 no longer pushes the movable part 41 outward. At this time, the adjustment plate 4 and the locking post 43 can be automatically reset again by the side spring 252, driving the locking post 43 to be locked in the locking cavity 33 on the upper side of the baffle 32, thereby fixing the movable post 3 and the baffle 32 on the left side in the baffle groove 23.

[0052] Then, when the movable plate 6 moves to the right through the roller conveying assembly 21, the movable column 3 and the baffle 32 on the right side are also fixed in the baffle groove 23. At this time, the positioning of the baffles 32 on the left and right sides on the tray 5 can be released.

[0053] Finally, it is only necessary to move the tray 5 as a whole to the left onto the workbench through the roller conveyor assembly 21. It is worth noting that in the process of the tray 5 as a whole moving to the left, the upper female bevel 521 on the side base 52 will push the movable part 41 on the left outward again, and the movable column 3 will move up again. However, at this time, the side base 52 is blocked above the baffle 32, so the movable column 3 cannot move up completely. When the tray 5 is about to be moved out, the magnetic part 54 at the bottom of the side base 52 and the middle plate 53 will be aligned with the baffle 32 on the left, so that the baffle 32 can be pushed to the bottom by the repulsive magnetic force between the magnetic part 54 and the baffle 32. At this time, the movable column 3 on the left can be fixed again by the mutual clamping between the clamping column 43 and the clamping cavity 33.

[0054] It is worth noting that both sides of the locking groove 522 are provided with slopes adapted to the sub-slopes 42. When the baffle 32 is locked on both sides of the tray 5, the locking groove 522 can lock the movable member 41. When the baffle 32 is located in the baffle groove 23, the slopes on both sides of the locking groove 522 can automatically squeeze the movable member 41 outward when the tray 5 moves.

[0055] In the second embodiment, the two workbenches are only arranged on one side of the track of the rail trolley body 1, for example, the right side. The pallet 5 is loaded from the workbench on the right side to the support seat 2 on the rail trolley body 1, and then the pallet 5 is transferred through the rail trolley body 1 and unloaded again from another workbench on the right side.

[0056] The loading process of the pallet 5 is the same as that of the first embodiment. When unloading the pallet 5, the roller conveyor assembly 21 is simply used to control the movable plate 6 to move rightward to fix the right movable column 3 and the baffle 32 in the baffle groove 23. At this time, the right baffle 32 can release the positioning of the pallet 5. Since the left side of the support base 2 does not need to be loaded or unloaded, there is no need to raise or lower the left baffle 32.

[0057] In the above embodiment, after the tray 5 is removed from the support base 2, the elastic cords 526 on both sides of the movable plate 6 can be used to pull the movable plate 6 to the middle of the movable cavity 523. At this time, the movable plate 6 can be moved upward by the magnetic force between the lower magnetic ring 65 and the upper magnetic ring 531, thereby returning the movable plate 6 to the top cavity 524.

[0058] Furthermore, wear-resistant pads are installed on the outer walls of the baffles 32 to ensure sufficient stability for the pallet 5 when the roller conveyor assembly 21 is idling beneath it. Additional positioning mechanisms can be installed on the pallet 5 to position the cargo above it. To ensure stable movement of the pallet 5 on the roller conveyor assembly 21, the weight of the cargo and workpieces must not exceed the maximum design load capacity of the pallet 5. Rough pads are installed on the bottoms of the side panels 61 to ensure effective transmission of the roller conveyor assembly 21 to the side panels 61. This is all prior art and will not be elaborated upon.

[0059] Furthermore, the repulsive magnetic force between the upper magnetic column 63 and the lower magnetic column 36, and the repulsive magnetic force between the magnetic part 54 and the baffle 32 are both greater than the elastic force of the lower spring 233. Therefore, the baffle 32 can be moved to the bottom of the baffle groove 23 by moving any of the above-mentioned magnetic forces.

[0060] In this structure, by arranging the movable column 3, the adjustment plate 4, the tray 5, and the movable plate 6, the tray 5 is positioned by the baffle 32 when it moves onto the support base 2, thereby ensuring the stability of the tray 5 and the cargo when the rail vehicle body 1 moves. Furthermore, when the tray 5 moves to a designated position, the baffle 32 can be automatically released by the movable plate 6 to enable the tray 5 to be removed.

[0061] While conventional roller conveyor assembly 21 is primarily used to transport tray 5, this solution utilizes roller conveyor assembly 21 to drive baffle 32 to position tray 5. This allows for automated positioning of tray 5 without requiring additional actuators, saving costs. The movable column 3, adjustment plate 4, tray 5, and movable plate 6 in this application are less expensive than conventional actuators.

[0062] In the present invention, the pallet 5 and the goods can be transported by the rail trolley body 1. By coordinating the movable column 3, the adjustment plate 4, the pallet 5 and the movable plate 6, the pallet 5 can be automatically positioned and unlocked to ensure the stability of the pallet 5 during transportation.

[0063] The above description is only a preferred specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any technician familiar with the technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solution and inventive concept of the present invention, should be covered by the scope of protection of the present invention.
