Description

Technical Field

[0001] This invention relates to the field of port logistics technology, specifically to a port logistics cargo transportation device. Background Technology

[0002] Port logistics is a relatively new term that has only recently appeared in academic discussions and various media outlets. It refers to the development of a comprehensive port service system by central port cities leveraging their port advantages and advanced hardware and software environments to enhance their ability to radiate logistics activities around the port. This system emphasizes the port's strengths in cargo collection, storage, and distribution, is based on port-related industries, supported by information technology, and aims to optimize port resource integration. Port logistics is a special form of integrated logistics system, serving as an irreplaceable and crucial node in the logistics process, providing both basic logistics services and derivative value-added services throughout the entire supply chain logistics system.

[0003] Currently, there are many small goods, especially boxed goods, in port logistics transportation. When transporting such goods, forklifts must first be used to deliver the goods into the container and stack them neatly before transportation. The speed of stacking is often the key factor in the speed of transportation. If the goods in the container are not stacked neatly, they need to be stacked and aligned manually, which is time-consuming and labor-intensive. Therefore, forklift operators must be experienced. However, experienced forklift operators are very rare. This results in many containers having to queue up and wait for forklift operators to stack the goods one by one, which prolongs the transportation time. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides a port logistics cargo transportation device. This device solves the problem that many small goods, especially boxed goods, require forklifts to be stacked neatly inside containers before transport. The speed of stacking is often a key factor in transport speed. If the goods inside the container are not stacked correctly, manual stacking is required, which is time-consuming and labor-intensive. Therefore, forklift operators must be highly experienced, but experienced forklift operators are scarce. This results in many containers queuing up, waiting for forklift operators to stack the goods in turn, thus extending the cargo transportation time.

[0017] This invention provides a port logistics cargo transportation device. It has the following beneficial effects:

[0018] This solution addresses the issue raised in the background section regarding the numerous small cargo items, particularly containerized cargo, in current port logistics transportation. For transporting such cargo, forklifts must first be used to neatly stack the goods inside the container before transport. The speed of stacking is often a key factor in transport speed. If the cargo inside the container is not stacked correctly, manual stacking is required, which is time-consuming and labor-intensive. Therefore, forklift operators must be highly experienced, but experienced forklift operators are scarce. This leads to many containers queuing up, waiting for forklift operators to stack the cargo one by one, thus extending the transport time. This solution first connects the towing hook to the tractor, then parks the mobile container next to the cargo, and then opens the single-axle container door. Make the single-axis box door leave the box door slot to expose the inside of the mobile container. Then open the platform placement cabinet, place the folding cargo storage platform, and then start the stacker crane through the control console and move the stacker crane to the folding cargo storage platform. Then place the goods on the folding cargo storage platform. At this time, the stacker crane will start, insert and pick up the goods, and then move the goods to the end of the mobile container near the towing hook through the slide rail. After putting down the goods, the stacker crane will return to the folding cargo storage platform to insert and pick up the goods again, and then move to the end of the mobile container near the towing hook again to put down the goods again. The goods will be moved to the inside of the mobile container by pushing them. Repeat the above operation until the first row of goods is stacked.

[0019] Once the first row of goods is stacked, the stacker crane will stack the second row of goods close to the first row. Starting from the end of the mobile container near the towing hook, the stacker crane will gradually stack the goods row by row towards the stacker crane's storage area. When the first layer is completely stacked, and the stacker crane retrieves goods again, it will lift the goods to a certain height and repeat the first layer operation, stacking the second layer row by row. After the second layer is completed, it will lift the height again to stack the third layer, until the mobile container is completely stacked. At this point, the stacker crane will move to the stacker crane's storage area via a slide rail, fold the folding cargo storage platform into the platform placement cabinet, and then close the platform placement cabinet and the single-axle door, automatically completing the stacking of goods without requiring manual stacking of goods inside the mobile container.

[0020] When the folding cargo storage platform contains goods, the lateral forks first insert the goods, and then the telescopic gate is activated to prevent the goods from falling accidentally when the lateral forks move. Subsequently, the pulley mechanism and the lifting column work together to transport the goods to any location inside the mobile container, automatically completing the stacking of the goods.

[0021] When the translating fork successfully picks up the goods, the fork mounting platform will rise a certain distance. The first T-shaped slide and the first T-shaped slide column are responsible for the specific direction of the fork mounting platform when it rises, so as to prevent the goods from being unsuccessfully stacked due to the direction of the rise when moving the goods in the future.

[0022] When the rail wheel moves by rotating on the slide rail, the I-shaped rail wheel is higher on both sides than in the middle, which can effectively prevent the rail wheel from accidentally derailing during movement.

[0023] The dual-movement mechanism ensures the stability of the machine base during movement and effectively distributes the weight of the machine base when it is carrying goods, preventing damage to the lifting column due to excessive weight. The T-shaped guide groove and T-shaped guide column also fix the specific direction of the T-shaped slider during movement. When descent is required, the second and third motors can be rotated in opposite directions. The pulley mechanism and lifting column can deliver the goods to any position inside the mobile container, preventing dead corners that cannot be stacked inside the mobile container.

[0024] The T-shaped locking block is responsible for assisting in fixing the direction of the translating fork during movement and preventing the translating fork from accidentally falling off the fork base during movement. Through the first sprocket, the second sprocket, and the drive chain, a small number of motors drive all the gears to rotate.

[0025] When the translating fork successfully picks up the goods, the door stops the goods a certain distance to fix the position of the goods and prevent the goods from accidentally falling off the translating fork during the translation process. When it is necessary to unload the goods from the translating fork, the door stops return to its original position to facilitate the unloading of the goods from the translating fork.

Detailed Implementation

[0038] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0039] like Figure 1 As shown, a port logistics cargo transportation device includes a towing hook 1 and a mobile container 2 suspended behind it. A stacker crane storage room 3 is provided at the end of the mobile container 2 away from the towing hook 1. A control console 4 is provided on the outer wall of one end of the stacker crane storage room 3. A stacker crane 5 is provided inside the stacker crane storage room 3. A container door slot 6 is provided at the end of the mobile container 2 near the stacker crane storage room 3. A single-axle container door 7 is provided in the container door slot 6. Several slide rails 8 are provided at the end of the mobile container 2 near the container door slot 6. A platform placement cabinet 9 is provided on the lower side of the end of the mobile container 2 near the slide rails 8. A folding cargo storage platform 10 is provided inside the platform placement cabinet 9.

[0040] like Figure 1 As shown, one end of the slide rail 8 extends into the stacker storage room 3, and the bottom end of the stacker 5 is connected to the slide rail 8.

[0041] With the above technical solution, when it is necessary to stack goods into the mobile container 2, the stacker crane 5 can stack the goods to any point in the mobile container 2 via the slide rail 8.

[0042] like Figure 2 and Figure 3 As shown, the stacker crane 5 includes a machine base 501. A plurality of pulley mechanisms 502 are provided at one end of the machine base 501 near the slide rail 8. Lifting columns 503 are respectively provided at one end of the machine base 501 near the traction hook 1 and at the other end away from the traction hook 1. Fork bases 504 are respectively provided on both sides of the top of the machine base 501 near the lifting columns 503. A translation fork 505 is provided at the end of the fork base 504 away from the machine base 501. A plurality of telescopic gates 506 are respectively provided at both ends of the translation fork 505.

[0043] Through the above technical solution, when the folding cargo storage platform 10 contains goods, the lateral fork 505 will start moving towards the goods. When the lateral fork 505 successfully picks up the goods, the telescopic gate 506 will activate to prevent the goods from accidentally falling during the movement of the lateral fork 505. At this time, the machine base 501 will rise a certain distance, and then the lateral fork 505 will return to its original position. Subsequently, the pulley mechanism 502 will activate, driving the stacker crane 5 and the goods to move towards the empty space inside the mobile container 2. When it moves to the corresponding position... If it is necessary to send the goods to a higher position, the lifting column 503 will be activated to raise the machine base 501 to a certain height. Then the lateral fork 505 will be activated and move into the mobile container 2. When the goods are moved to the corresponding position in the mobile container 2, the telescopic gate 506 and the machine base 501 will return to their original positions one after another. Then the lateral fork 505 will return to its original position, and then the pulley mechanism 502 will drive the machine base 501 to the folding cargo storage platform 10. Then the above operation will be repeated.

[0044] like Figure 4 As shown, the machine base 501 includes a base body 50101. The upper end of the base body 50101 is provided with a first groove 50102 and a plurality of first T-shaped slide grooves 50103. A plurality of hydraulic rods 50104 are provided in the first groove 50102. A fork mounting platform 50105 is provided at one end of the hydraulic rods 50104 away from the base body 50101. A first T-shaped slide column 50106 is provided in the first T-shaped slide groove 50103. One end of the first T-shaped slide column 50106 is connected to the fork mounting platform 50105.

[0045] With the above technical solution, when the translation fork 505 successfully inserts the goods, the hydraulic rod 50104 is activated, causing the fork mounting platform 50105 to rise a certain distance. The first T-shaped slide 50103 and the first T-shaped slide column 50106 are responsible for the specific direction of the fork mounting platform 50105 when it is raised, so as to prevent the goods from not being successfully stacked due to the direction of raising when moving the goods in the future.

[0046] like Figure 5 As shown, the pulley mechanism 502 has a first motor 50201 inside the machine base 501. A first gear 50202 is provided at one end of the first motor 50201, and a second gear 50203 is provided at one end of the first gear 50202. The first gear 50202 and the second gear 50203 mesh with each other. A third gear 50204 is provided at the ends of the first gear 50202 and the second gear 50203 that are away from each other. A transmission column 50205 is provided at the end of the third gear 50204 that is away from the first motor 50201, and a track wheel 50206 is provided at the other end of the transmission column 50205.

[0047] With the above technical solution, when the stacker crane 5 needs to be moved horizontally, the first motor 50201 starts, driving the first gear 50202 to start rotating. Then the first gear 50202 drives the second gear 50203 to rotate. At this time, the first gear 50202 and the second gear 50203 drive the third gear 50204 to rotate. The third gear 50204, through the transmission column 50205, causes the rail wheel 50206 to start rotating. At this time, the stacker crane 5 can move horizontally inside the mobile container 2 and deliver the goods to the empty space in the mobile container 2.

[0048] like Figure 1 and Figure 5 As shown, the track wheel 50206 is I-shaped, the track wheel 50206 is mounted on the slide rail 8, and the track wheel 50206 moves through the slide rail 8.

[0049] With the above technical solution, when the guide wheel 50206 moves by rotation on the slide rail 8, the two sides of the I-shaped guide wheel 50206 are higher than the middle, which can effectively prevent the guide wheel 50206 from accidentally derailing during movement.

[0050] like Figure 6 and Figure 7 As shown, the lifting column 503 includes a column body 50301, a second groove 50302 is provided inside the column body 50301, a plurality of pulleys 50303 are respectively provided at both ends of the second groove 50302 near the pulley mechanism 502, a second motor 50304 is provided inside the pulleys 50303, a synchronous belt 50305 is provided on two pulleys 50303 at the same end, and a first rack 50306 is provided between the two pulleys 50303 at the same end;

[0051] A T-shaped slider 50307 is provided between the pulleys 50303 at both ends. One end of the T-shaped slider 50307 is connected to the machine base 501. Several third motors 50308 are respectively provided at both ends of the T-shaped slider 50307 near the first rack 50306. A fourth gear 50309 is provided at the end of the third motor 50308 near the first rack 50306. The fourth gear 50309 meshes with the first rack 50306. The synchronous belts 50305 at both ends are connected to the T-shaped slider 50307. A T-shaped guide groove 503010 is provided at the end of the T-shaped slider 50307 near the synchronous belt 50305. A T-shaped guide post 503011 is provided in the T-shaped guide groove 503010.

[0052] Through the above technical solution, when the machine base 501 needs to be moved to the required height, the second motor 50304 and the third motor 50308 are started. The second motor 50304 drives the pulley 50303 to rotate, and the pulley 50303 drives the T-shaped slider 50307 to move upward through the synchronous belt 50305. Meanwhile, the third motor 50308 drives the fourth gear 50309 to rotate, and the fourth gear 50309 drives the T-shaped slider 50307 to move upward through the first rack 50306. Through this dual movement method, the movement of the machine base 501 is ensured. The machine base 501 is stable and the dual movement mode can effectively distribute the weight generated when the goods are moved, preventing damage to the lifting column 503 due to excessive weight. The T-shaped guide groove 503010 and T-shaped guide column 503011 are also responsible for fixing the specific direction of the T-shaped slider 50307 when it moves. When it needs to be lowered, the second motor 50304 and the third motor 50308 can be rotated in opposite directions. The goods can be sent to any position in the mobile container 2 through the pulley mechanism 502 and the lifting column 503, and the stacking of goods can be completed automatically.

[0053] like Figure 8 and Figure 9 As shown, the fork base 504 includes a base body 50401. A plurality of sliders 50402 are disposed on the top surface of the base body 50401. A T-shaped locking block 50403 is disposed between two sliders 50402. A plurality of fifth gears 50404 are disposed between two T-shaped locking blocks 50403. A sixth gear 50405 is disposed between two fifth gears 50404. A first T-shaped transmission column 50406 is disposed at one end of the fifth gear 50404 near the base body 50401. A first sprocket 50407 is disposed at one end of the first T-shaped transmission column 50406 away from the fifth gear 50404. A transmission chain 504011 is disposed on the first sprocket 50407. A fourth motor 50408 is disposed at one end of the first sprocket 50407 away from the first T-shaped transmission column 50406.

[0054] The sixth gear 50405 is provided with a second T-shaped transmission column 50409 at one end near the base body 50401, and a second sprocket 504010 is provided at the other end of the second T-shaped transmission column 50409 away from the sixth gear 50405. The first sprocket 50407 and the second sprocket 504010 are connected to each other by a transmission chain 504011.

[0055] Through the above technical solution, when the translation fork 505 needs to be moved, the fourth motor 50408 is started. The fourth motor 50408 causes the first sprocket 50407 to start rotating. Then, the first sprocket 50407 drives the second sprocket 504010 to rotate via the transmission chain 504011. Subsequently, the first sprocket 50407 and the second sprocket 504010 drive the first T-shaped drive column 50406 and the second T-shaped drive column 50409 to rotate. The first T-shaped drive column 50406 and the second T-shaped drive column 50409... The fifth gear 50404 and the sixth gear 50405 are driven to rotate, and the fifth gear 50404 and the sixth gear 50405 cause the translation fork 505 to move along the direction of the slider 50402. The T-shaped block 50403 is responsible for assisting in fixing the direction of the translation fork 505 when it moves, and preventing the translation fork 505 from accidentally falling off the fork base 504 when it moves. Through the first sprocket 50407, the second sprocket 504010 and the transmission chain 504011, a small number of motors drive all the gears to rotate.

[0056] like Figure 10As shown, the translation fork 505 includes a fork housing 50501. The interior of the fork housing 50501 near the fork base 504 is provided with a plurality of first sliding grooves 50502. A plurality of T-shaped slots 50503 are provided between two first sliding grooves 50502. A second sliding groove 50504 is provided between two T-shaped slots 50503. A second rack 50505 is provided on one inner wall of the second sliding groove 50504.

[0057] With the above technical solution, when it is necessary to move the fork housing 50501, the fork housing 50501 can be moved arbitrarily to both sides by the mutual cooperation of the second rack 50505, the fifth gear 50404, and the sixth gear 50405 through the direction of rotation. The first slide groove 50502 and the T-shaped slot 50503 are responsible for fixing the direction and specific position of the fork housing 50501 when it moves.

[0058] like Figure 11 As shown, the telescopic gate 506 includes a gate 50601, with a third groove 50602 at each end of the gate 50601. A third rack 50603 is provided in the third groove 50602, and a seventh gear 50604 is provided at one end of the third rack 50603. The third rack 50603 and the seventh gear 50604 mesh with each other, and a fifth motor 50605 is provided at one end of the seventh gear 50604.

[0059] With the above technical solution, when the translating fork 505 successfully picks up the goods, the fifth motor 50605 starts, causing the seventh gear 50604 to start rotating. At this time, the stop gate 50601 moves a distance towards the goods through the third rack 50603 meshing with the seventh gear 50604, fixing the position of the goods and preventing the goods from accidentally falling off the translating fork 505 during translation. When it is necessary to unload the goods from the translating fork 505, the fifth motor 50605 starts again and rotates in the opposite direction, causing the stop gate 50601 to return to its original position, making it convenient for the translating fork 505 to unload the goods.

[0060] Working principle:

[0061] This solution first connects the towing hook 1 to the tractor, then parks the mobile container 2 next to the cargo, then opens the single-axle door 7, allowing it to leave the door slot 6 and reveal the interior of the mobile container 2. Next, it opens the platform placement cabinet 9 and places the folding cargo storage platform 10. Then, it starts the stacker crane 5 via the control console 4 and moves the stacker crane 5 to the folding cargo storage platform 10. The cargo is then placed on the folding cargo storage platform 10. At this time, the stacker crane 5 will start, pick up the cargo, and then move the cargo to the end of the mobile container 2 near the towing hook 1 via the slide rail 8. After putting down the cargo, the stacker crane 5 will return to the folding cargo storage platform 10 to pick up the cargo again, and then move to the end of the mobile container 2 near the towing hook 1 again to put down the cargo. The cargo is then pushed to move the initial cargo to the inside of the mobile container 2. The above operation is repeated until the first row of cargo is stacked.

[0062] When the first row of goods is stacked, the stacker crane 5 will stack the second row of goods close to the first row of goods. The goods will be stacked row by row from the end of the mobile container 2 near the towing hook 1 to the end near the stacker crane storage room 3. When the first layer is completely stacked, when the stacker crane 5 picks up the goods again, the stacker crane 5 will lift the goods to a certain height and repeat the operation of the first layer to stack the second layer row by row. After the second layer is stacked, the height will be raised again to stack the third layer until the mobile container 2 is completely stacked. At this time, the stacker crane 5 will move to the stacker crane storage room 3 through the slide rail 8, and then fold the folding cargo storage table 10 into the platform placement cabinet 9. Then the platform placement cabinet 9 and the single-axis box door 7 will be closed, and the stacking of goods will be completed automatically without the need for manual stacking of goods in the mobile container.

[0063] When the folding cargo storage platform 10 contains goods, the lateral fork 505 will move towards the goods. When the lateral fork 505 successfully picks up the goods, the telescopic gate 506 will activate to prevent the goods from accidentally falling during the movement of the lateral fork 505. At this time, the machine base 501 will rise a certain distance, and then the lateral fork 505 will return to its original position. Subsequently, the pulley mechanism 502 will activate, driving the stacker crane 5 and the goods to move to the empty space inside the mobile container 2. When the goods need to be sent to a higher position, the lifting column 503 will activate, raising the machine base 501 to a certain height. Then the lateral fork 505 will activate and move into the mobile container 2. When the goods are moved to the corresponding position inside the mobile container 2, the telescopic gate 506 and the machine base 501 will return to their original positions one after another. Then the lateral fork 505 will return to its original position, and then the pulley mechanism 502 will drive the machine base 501 to the folding cargo storage platform 10. Then the above operation will be repeated.

[0064] When the translating fork 505 successfully picks up the goods, the hydraulic rod 50104 is activated, raising the fork mounting platform 50105 a certain distance. The first T-shaped slide 50103 and the first T-shaped slide column 50106 are responsible for the specific direction of the fork mounting platform 50105 when it is raised, so as to prevent the goods from being unsuccessfully stacked due to the direction of raising when moving the goods in the future.

[0065] When the stacker crane 5 needs to be moved horizontally, the first motor 50201 starts, driving the first gear 50202 to start rotating. Then, the first gear 50202 drives the second gear 50203 to rotate. At this time, the first gear 50202 and the second gear 50203 drive the third gear 50204 to rotate. The third gear 50204, through the transmission column 50205, causes the rail wheel 50206 to start rotating. At this time, the stacker crane 5 can move horizontally inside the mobile container 2 and deliver the goods to the empty space in the mobile container 2.

[0066] When the guide wheel 50206 moves by rotation on the slide rail 8, the two sides of the I-shaped guide wheel 50206 are higher than the middle, which can effectively prevent the guide wheel 50206 from accidentally derailing during movement.

[0067] When the machine base 501 needs to be raised to the required height, the second motor 50304 and the third motor 50308 are activated. The second motor 50304 drives the pulley 50303 to rotate, and the pulley 50303 drives the T-shaped slider 50307 to move upward via the synchronous belt 50305. Meanwhile, the third motor 50308 drives the fourth gear 50309 to rotate, and the fourth gear 50309 drives the T-shaped slider 50307 to move upward via the first rack 50306. Through this dual movement mechanism, the stability of the machine base 501 during movement is ensured. The dual movement mechanism effectively distributes the weight of the machine base 501 when it is carrying goods, preventing damage to the lifting column 503 due to excessive weight. The T-shaped guide groove 503010 and T-shaped guide column 503011 are also responsible for fixing the specific direction of the T-shaped slider 50307 when it moves. When it needs to be lowered, the second motor 50304 and the third motor 50308 can be rotated in opposite directions. The goods can be sent to any position in the mobile container 2 through the pulley mechanism 502 and the lifting column 503, automatically completing the stacking of goods.

[0068] When the translating fork 505 needs to be moved, the fourth motor 50408 is activated. The fourth motor 50408 causes the first sprocket 50407 to start rotating. Then, the first sprocket 50407 drives the second sprocket 504010 to rotate via the transmission chain 504011. Subsequently, the first sprocket 50407 and the second sprocket 504010 drive the first T-shaped drive column 50406 and the second T-shaped drive column 50409 to rotate. The first T-shaped drive column 50406 and the second T-shaped drive column 50409 drive the fifth... Gears 50404 and 50405 rotate, causing the translation fork 505 to move along the direction of slider 50402 via the fifth gear 50404 and 50405. The T-shaped locking block 50403 is responsible for assisting in fixing the direction of the translation fork 505 during movement and preventing the translation fork 505 from accidentally falling off the fork base 504 during movement. Through the first sprocket 50407, the second sprocket 504010, and the drive chain 504011, a small number of motors drive all the gears to rotate.

[0069] When the fork housing 50501 needs to be moved, the fork housing 50501 can be moved arbitrarily to both sides by the cooperation of the second rack 50505, the fifth gear 50404, and the sixth gear 50405 through the direction of rotation. The first slide groove 50502 and the T-shaped slot 50503 are responsible for fixing the direction and specific position of the fork housing 50501 when it moves.

[0070] When the translating fork 505 successfully picks up the goods, the fifth motor 50605 starts, causing the seventh gear 50604 to start rotating. At this time, the stop gate 50601 moves a distance towards the goods through the third rack 50603 that meshes with the seventh gear 50604, fixing the position of the goods and preventing the goods from accidentally falling off the translating fork 505 during translation. When it is necessary to unload the goods from the translating fork 505, the fifth motor 50605 starts again and rotates in the opposite direction, causing the stop gate 50601 to return to its original position, making it convenient for the translating fork 505 to unload the goods.
