[0019] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the protection scope of this application.

[0020] In modern manufacturing, especially in fields such as electronics, food, and chemicals, factory layouts typically consist of multiple independent functional buildings. For example, raw material storage might be located in Building A, production and processing workshops in Building B, and finished product storage in Building C. Related technologies usually rely on manually operated forklifts or hydraulic pallet trucks to transport the products between these different buildings.

[0021] Manual transportation relies heavily on manpower, resulting in high labor intensity, high labor costs, and low efficiency. Furthermore, the transportation process is significantly affected by outdoor weather; extreme weather conditions can halt transportation, causing production interruptions and losses. Moreover, manual transportation carries high safety risks, including damage from falling goods, employee injuries, and vehicle collisions. Additionally, manual transportation requires outdoor driveways, which may also serve as fire lanes, and frequent communication between transport vehicles can pose safety hazards.

[0022] To solve the above technical problems, such as Figures 1 to 5 As shown, this disclosure provides a transportation device for transporting a product 8 between a first building and a second building. The transportation device includes a first lifting mechanism 1, a second lifting mechanism 2, and a conveying mechanism 3. The first lifting mechanism 1 is located close to the first building and includes a first frame 11 and a first lifting platform 12 movably disposed within the first frame 11. The first frame 11 has a first cargo inlet / outlet communicating with the interior space of the first building on one side at a first height position, and a second cargo inlet / outlet on the other side at a second height position. A first conveying component 13 is provided on the first lifting platform 12; wherein, the second height position is higher than... At the first height position; the second lifting mechanism 2 is located near the second building. The second lifting mechanism 2 includes a second frame 21 and a second lifting platform 22 that is liftably installed within the second frame 21. The second frame 21 has a third cargo inlet / outlet connected to the indoor space of the second building on one side at the first height position, and a fourth cargo inlet / outlet on the other side at the second height position. The fourth cargo inlet / outlet is opposite to the second cargo inlet / outlet. The second lifting platform 22 is equipped with a second conveying component 23. The conveying mechanism 3 is connected between the first frame 11 and the second frame 21, and the conveying surface of the conveying mechanism 3 is flush with the bottom surfaces of the second cargo inlet / outlet and the fourth cargo inlet / outlet.

[0023] It is understood that in this embodiment, by setting the conveying mechanism 3 at a second height, the product 8 to be conveyed is transported between the first and second buildings at the second height position, without occupying the outdoor driveway and avoiding safety hazards caused by the transport device occupying the outdoor fire lane. Here, the first height is the height of the first floor, and the second height is the height of the second floor.

[0024] In this embodiment, a first lifting mechanism 1 is installed at the location of the first building. The first lifting mechanism 1 includes a first frame 11 and a first lifting platform 12. A second lifting mechanism 2 is installed near the second building and includes a second frame 21 and a second lifting platform 22. The first cargo inlet / outlet of the first frame 11 is used to load the product 8 to be transported from the interior of the first building onto the first lifting platform 12. After the first lifting platform 12 raises the height of the product 8, it transports the product 8 to the conveying mechanism 3 through the first conveying component 13 and the second cargo inlet / outlet. The conveying mechanism 3 can transport the product 8 and allow it to enter the second lifting platform 22 through the fourth cargo inlet / outlet. After the second lifting platform 22 lowers the height of the product 8, it transports the product 8 to the interior space of the second building through the second conveying component 23 and the third cargo inlet / outlet, thus realizing the transport of the product 8 between the first and second buildings. Therefore, mechanized transportation can replace manual transportation, greatly reducing labor costs and improving transportation efficiency.

[0025] The product 8 to be transported can be transported not only from the first building to the second building, but also from the second building to the first building. The specific process is as follows: The product 8 to be transported can be loaded into the second lifting platform 22 through the third cargo inlet / outlet. After the second lifting platform 22 raises the height of the product 8 to be transported, it is transported to the conveying mechanism 3 through the second conveyor 23 and the fourth cargo inlet / outlet. The conveying mechanism 3 can transport the product 8 to be transported, and then the product 8 enters the first lifting platform 12 through the second cargo inlet / outlet. After the first lifting platform 12 lowers the height of the product 8 to be transported, it is transported to the indoor space of the first building through the first conveyor 13 and the first cargo inlet / outlet, thus realizing the transport of the product 8 between the second building and the first building.

[0026] In some embodiments, the first building and the second building are arranged opposite to each other. The first lifting mechanism 1 is disposed on the outer surface of the first building facing the second building, and the second lifting mechanism 2 is disposed on the outer surface of the second building facing the first building.

[0027] In some embodiments, both the first frame 11 and the second frame 21 are enclosed frames. Specifically, the tops and sides of the first frame 11 and the second frame 21 are enclosed, with cargo inlets and outlets only located at corresponding positions. This allows the first lifting platform 12 and the second lifting platform 22 to be raised and lowered in an enclosed environment, thus ensuring that their operation is unaffected by external weather conditions, even in severe weather such as heavy rain, heavy snow, and strong winds.

[0028] In some embodiments, both the first frame 11 and the second frame 21 are metal frames.

[0029] In some embodiments, the first frame 11 has a first goods inlet / outlet located on the side facing the first building, corresponding to the first floor of the first building, and a second goods inlet / outlet located on the side facing away from the first building, corresponding to the second floor of the first building. The first building has a first opening at the location corresponding to the first goods inlet / outlet, allowing the first goods inlet / outlet to connect the first frame 11 to the interior space of the first floor of the first building; the first building also has a second opening at the location corresponding to the second goods inlet / outlet, allowing the second goods inlet / outlet to connect the first frame 11 to the interior space of the second floor of the first building. The first floors of the first building and the second floors of the second building are flush, and the second floors of the first building and the second floors of the second building are flush.

[0030] In some embodiments, the second frame 21 has a third cargo inlet / outlet at a location corresponding to the first floor of the second building on the side facing the second building, and a fourth cargo inlet / outlet at a location corresponding to the second floor of the second building on the side facing away from the second building. The second building has a third opening at the location corresponding to the third cargo inlet / outlet, allowing the third cargo inlet / outlet to connect the second frame 21 to the interior space of the first floor of the second building; the second building also has a fourth opening at the location corresponding to the fourth cargo inlet / outlet, allowing the fourth cargo inlet / outlet to connect the second frame 21 to the interior space of the second floor of the second building.

[0031] In some embodiments, the first, second, third, and fourth goods inlets / outlets have the same shape and size, and are all larger than the size of the product 8 to be transported. For example, the product 8 to be transported is a cuboid shape, and the first, second, third, and fourth goods inlets / outlets are all set as rectangular openings, with the height of the rectangular opening being greater than the height of the product 8 to be transported, and the width of the rectangular opening being greater than the width of the product 8 to be transported.

[0032] In some embodiments, the first lifting platform 12 and the second lifting platform 22 are not limited to being electric lifting platforms, but can also be configured as lifting cars, etc., so that the first lifting platform 12 can be lifted and lowered within the first frame 11 and the second lifting platform 22 can be lifted and lowered within the second frame 21.

[0033] In some embodiments, the first conveying member 13 is a mechanism such as a roller conveyor, plate chain, or conveyor belt disposed on the upper surface of the first lifting platform 12, which enables the horizontal conveying of the product 8 to be conveyed on the first lifting platform 12. The first conveying member 13 can convey in both forward and reverse directions under the drive of a driving member. That is, the first conveying member 13 can horizontally convey the product 8 to be conveyed along the direction from the first goods inlet / outlet to the second goods inlet / outlet, or it can horizontally convey the product 8 to be conveyed along the direction from the second goods inlet / outlet to the first goods inlet / outlet.

[0034] In some embodiments, the second conveying member 23 is a mechanism such as a roller conveyor, plate chain, or conveyor belt disposed on the upper surface of the second lifting platform 22, which enables the horizontal conveying of the product 8 to be conveyed on the second lifting platform 22. The second conveying member 23 can convey in both forward and reverse directions under the drive of a driving member. That is, the second conveying member 23 can horizontally convey the product 8 to be conveyed along the direction from the third goods inlet / outlet to the fourth goods inlet / outlet, or it can horizontally convey the product 8 to be conveyed along the direction from the fourth goods inlet / outlet to the third goods inlet / outlet.

[0035] In some embodiments, the first conveying member 13 can simultaneously convey the product 8 to be conveyed during the lifting and lowering of the first lifting platform 12, or the first conveying member 13 can convey the product 8 to be conveyed when the first lifting platform 12 is in a stopped lifting and lowering state. The second conveying member 23 can simultaneously convey the product 8 to be conveyed during the lifting and lowering of the second lifting platform 22, or the second conveying member 23 can convey the product 8 to be conveyed when the second lifting platform 22 is in a stopped lifting and lowering state.

[0036] In some embodiments, the conveying mechanism 3 is used to realize the horizontal conveying of the product 8 to be conveyed at a second height position. The conveying mechanism 3 includes, but is not limited to, roller conveyors, belt conveyors, etc.

[0037] like Figure 2 and Figure 3 As shown in some embodiments, multiple transport devices may be provided between the first building and the second building.

[0038] like Figure 3 As shown, in some embodiments, the transport device further includes a first connecting platform 6 disposed in the first building. The first connecting platform 6 is disposed near the first cargo import / export, and the first cargo import / export is disposed opposite to the third cargo import / export. The first connecting platform 6 includes a first connecting frame 61 and a third conveying component 62 disposed on the first connecting frame 61. The first connecting frame 61 forms a first connecting area 63 for accommodating the first connecting vehicle 4.

[0039] Understandably, the first shuttle vehicle 4 can transport the product 8 to be transported from the storage area within the first building to the first shuttle platform 6, or transport the product 8 received on the first shuttle platform 6 to the storage area of ​​the first building. Specifically, the first shuttle vehicle 4 transports the product 8 to be transported from the storage area within the first building to the first shuttle platform 6. The third conveyor 62 on the first shuttle platform 6 transports the product 8 to the first cargo inlet / outlet, and then through the first cargo inlet / outlet to the first lifting platform 12. The product 8 is then transported to the second building via the first lifting platform 12, the first conveyor 13, the conveying mechanism 3, the second conveyor 23, and the second lifting platform 22. Alternatively, the product 8 is transported to the first shuttle platform 6 via the second lifting platform 22, the second conveyor 23, the conveying mechanism 3, the first conveyor 13, and the first lifting platform 12. The third conveyor 62 on the first shuttle platform 6 transports the product 8 to the first shuttle vehicle 4, and then the first shuttle vehicle 4 transports the product 8 to the storage area of ​​the first building.

[0040] In some embodiments, the first connecting frame 61 is a horizontally arranged frame on which a third conveyor 62 is provided. The first connecting frame 61 may form a first connecting area 63 on the side away from the first cargo inlet / outlet, and the first connecting area 63 has third conveyors 62 on both opposite sides, so that after the first connecting vehicle 4 transports the product 8 to be transported to the first connecting area 63, the product 8 to be transported can be transported by the third conveyor 62.

[0041] In some embodiments, the first shuttle vehicle 4 is an AGV (Automated Guided Vehicle), which enables automated transportation of the product 8 to be transported, further reducing labor costs. Charging stations can be installed within the first building to charge the first shuttle vehicle 4.

[0042] like Figure 4 As shown, in some embodiments, the first connecting frame 61 includes a first frame 611 and a second frame 612 spaced apart, and a third frame 613 and a fourth frame 614 spaced apart between the first frame 611 and the second frame 612. The third frame 613 is positioned closer to the first frame 611 than the fourth frame 614. The third conveying member 62 includes a first conveying section 621 located between the first frame 611 and the third frame 613, a second conveying section 622 located between the second frame 612 and the fourth frame 614, and a third conveying section 623 located between the first frame 611 and the second frame 612. The third conveying section 623 is positioned close to the first cargo inlet / outlet, and the area between the third frame 613 and the fourth frame 614 serves as the first connecting area 63.

[0043] It is understood that the first frame 611 and the second frame 612 are of the same length, and the third frame 613 and the fourth frame 614 are of the same length, with the first frame 611 being longer than the third frame 613. The first frame 611, the second frame 612, the third frame 613, and the fourth frame 614 are of the same height, so that the first conveying section 621, the second conveying section 622, and the third conveying section 623 are at the same height. The first conveying section 621 and the second conveying section 622 are arranged in parallel and are located on opposite sides of the first connecting area 63.

[0044] Before the first shuttle vehicle 4 enters the first shuttle area 63, the height of the product 8 to be transported on the first shuttle vehicle 4 is higher than the first conveying section 621 and the second conveying section 622. When the first shuttle vehicle 4 enters the first shuttle area 63, the first lifting mechanism on the first shuttle vehicle 4 can perform a lowering action to reduce the height of the product 8 to be transported, so that the product 8 can fall onto the first conveying section 621 and the second conveying section 622, and then enter the third conveying section 623 under the conveying of the first conveying section 621. Then, under the conveying of the third conveying section 623, it is transported through the first cargo inlet and outlet to the first lifting platform 12, thereby realizing the transport of the product 8 from the first building to the second building. It should be noted that the first lifting mechanism can perform the lifting action simultaneously with the first shuttle vehicle 4 entering the first shuttle area 63, or the first lifting mechanism can perform the lifting action after the first shuttle vehicle 4 has completely entered the first shuttle area 63.

[0045] Conversely, when the product 8 to be transported is moved from the second building to the first building, it enters the third conveying section 623 from the first lifting platform 12 under the conveying of the first conveyor 13, and then enters the first conveying section 621 and the second conveying section 622 under the action of the third conveying section 623. At this time, the first connecting area 63 has the first connecting vehicle 4 parked there. The first lifting mechanism of the first connecting vehicle 4 rises to support the product 8 to be transported and to remove the product 8 from the first conveying section 621 and the second conveying section 622. Then the first connecting vehicle 4 drives to the storage area of ​​the first building to complete the transport of the product 8. It should be noted that the first lifting mechanism of the first connecting vehicle 4 can perform the lifting action after the product 8 to be transported has completely entered the first conveying section 621 and the second conveying section 622.

[0046] In some embodiments, the first frame 611, the second frame 612, the third frame 613, and the fourth frame 614 are all metal frames. The first conveyor section 621, the second conveyor section 622, and the third conveyor section 623 are all roller conveyors.

[0047] In some embodiments, the width of the product 8 to be transported is greater than the distance between the third frame 613 and the fourth frame 614, but less than the distance between the first frame 611 and the second frame 612. The width of the first lifting mechanism on the first shuttle vehicle 4 is less than or equal to the distance between the third frame 613 and the fourth frame 614, so that the first shuttle vehicle 4 can drive into the first shuttle area 63. By ensuring that the center of gravity of the product 8 to be transported is located on the axis of the first shuttle vehicle 4, stable transport of the product 8 can be ensured, thus preventing the product 8 from falling off the first shuttle vehicle 4.

[0048] In some embodiments, the upper surface of the first shuttle vehicle 4 is provided with a first lifting mechanism, which is configured to place the product 8 to be transported. The first connecting platform 6 is provided with a first sensor, which is signal-connected to the first lifting mechanism. The first sensor is configured to sense the position of the first shuttle vehicle 4 and drive the first lifting mechanism to perform a lowering action in response to the first shuttle vehicle 4 approaching the first connecting area 63, and drive the first lifting mechanism to perform a lifting action in response to the first shuttle vehicle 4 moving away from the first connecting area 63.

[0049] When the product 8 to be transported is transported from the first building to the second building, the first shuttle vehicle 4 transports the product 8 to the first shuttle area 63. When the first sensor senses that the first shuttle vehicle 4 is approaching the first shuttle area 63, the first sensor can send a first sensing signal to the central control mechanism. The central control mechanism can drive the first lifting mechanism to perform a lowering action based on the first sensing signal, so that the height of the product 8 to be transported decreases and it can fall into the first conveying section 621 and the second conveying section 622. Under the conveying of the first conveying section 621 and the second conveying section 622, it enters the third conveying section 623. Then, under the conveying of the third conveying section 623, it is transported through the first cargo inlet and outlet to the first lifting platform 12, thereby realizing the transport of the product 8 from the first building to the second building. After the first shuttle vehicle 4 completes one transport, it will leave the first shuttle area 63. At this time, the first sensor senses that the first shuttle area 63 is far away from the first shuttle area 63 and can send a second sensing signal to the central control mechanism. The central control mechanism can drive the first lifting mechanism to lift based on the second sensing signal so that the upper surface of the first shuttle vehicle 4 is at a suitable height for subsequent loading.

[0050] When the product 8 to be transported is transported from the second building to the first building, it enters the third transport section 623 from the first lifting platform 12 under the transport of the first transport component 13, and then enters the first transport section 621 and the second transport section 622 under the action of the third transport section 623. During this process, the first shuttle vehicle 4 also moves towards the first connecting area 63. When the first sensor senses that the first shuttle vehicle 4 is approaching the first connecting area 63, the first sensor can send a first sensing signal to the central control mechanism. The central control mechanism can drive the first lifting mechanism to perform a lowering action based on the first sensing signal, so that the upper surface of the first lifting mechanism is flush with the lower surface of the product 8 to be transported, so that the product 8 to be transported can be supported by the first shuttle vehicle 4. Once the product 8 to be transported is completely located in the first shuttle vehicle 4, the first shuttle vehicle 4 will leave the first shuttle area 63. At this time, the first sensor senses that the first shuttle area 63 is far away from the first shuttle area 63 and can send a second sensing signal to the central control mechanism. The central control mechanism can drive the first lifting mechanism to perform a lifting action based on the second sensing signal, so that the first lifting mechanism lifts the product 8 to be transported, so that the product 8 to be transported is separated from the first conveying section 621 and the second conveying section 622, and the product 8 to be transported can be transported to the storage area of ​​the first building under the transportation of the first shuttle vehicle 4.

[0051] like Figure 3 As shown, in some embodiments, the transport device further includes a second connecting platform 7 located in the second building, the second connecting platform 7 being located near the third cargo import / export, the second connecting platform 7 including a second connecting frame 71 and a fourth conveyor 72 disposed on the second connecting frame 71, wherein the second connecting frame 71 forms a second connecting area 73 for accommodating the second connecting vehicle 5.

[0052] Understandably, the second shuttle vehicle 5 can transport the product 8 to be transported from the storage area within the second building to the second shuttle platform 7, or transport the product 8 received on the second shuttle platform 7 to the storage area of ​​the second building. Specifically, the second shuttle vehicle 5 transports the product 8 to be transported from the storage area within the second building to the second shuttle platform 7. The fourth conveyor 72 on the second shuttle platform 7 transports the product 8 to the third cargo import / export, and then through the third cargo import / export to the second lifting platform 22. The product 8 is then transported to the first building via the second lifting platform 22, the second conveyor 23, the conveying mechanism 3, the first conveyor 13, and the first lifting platform 12. Alternatively, the product 8 is transported to the second shuttle platform 7 via the first lifting platform 12, the first conveyor 13, the conveying mechanism 3, the second conveyor 23, and the second lifting platform 22. The fourth conveyor 72 on the second shuttle platform 7 transports the product 8 to the second shuttle vehicle 5, and then the second shuttle vehicle 5 transports the product 8 to the storage area of ​​the second building.

[0053] In some embodiments, the second connecting frame 71 is a horizontally arranged frame on which a fourth conveyor 72 is provided. The second connecting frame 71 may form a second connecting area 73 on the side away from the third cargo inlet / outlet, and the second connecting area 73 has a fourth conveyor 72 on both opposite sides, so that after the second connecting vehicle 5 transports the product 8 to be transported to the second connecting area 73, the product 8 to be transported can be transported by the fourth conveyor 72.

[0054] In some embodiments, the second shuttle vehicle 5 is an AGV transport vehicle, which enables automated transport of the product 8 to be delivered, further reducing labor costs. Charging piles can be installed inside the second building to charge the second shuttle vehicle 5.

[0055] like Figure 5 As shown, in some embodiments, the second connecting frame 71 includes a fifth frame 711 and a sixth frame 712 spaced apart, and a seventh frame 713 and an eighth frame 714 spaced apart between the fifth frame 711 and the sixth frame 712. The seventh frame 713 is positioned closer to the fifth frame 711 than the eighth frame 714. The fourth conveying member 72 includes a fourth conveying section 721 located between the fifth frame 711 and the seventh frame 713, a fifth conveying section 722 located between the sixth frame 712 and the eighth frame 714, and a sixth conveying section 723 located between the fifth frame 711 and the sixth frame 712. The sixth conveying section 723 is positioned close to the third cargo inlet / outlet. The area between the seventh frame 713 and the eighth frame 714 serves as the second connecting area 73.

[0056] Understandably, the fifth frame 711 and the sixth frame 712 are of the same length, and the seventh frame 713 and the eighth frame 714 are of the same length, with the fifth frame 711 being longer than the seventh frame 713. The fifth frame 711, the sixth frame 712, the seventh frame 713, and the eighth frame 714 are of the same height, so that the fourth conveyor section 721, the fifth conveyor section 722, and the sixth conveyor section 723 are at the same height. The fourth conveyor section 721 and the fifth conveyor section 722 are arranged in parallel and are located on opposite sides of the second connection area 73.

[0057] Before the second shuttle bus 5 enters the second shuttle area 73, the height of the product 8 to be transported on the second shuttle bus 5 is higher than that of the fourth conveying section 721 and the fifth conveying section 722. When the second shuttle bus 5 enters the second shuttle area 73, the second lifting mechanism on the second shuttle bus 5 can lower the height of the product 8 to fall onto the fourth conveying section 721 and the fifth conveying section 722. The product 8 is then transported by the fourth and fifth conveying sections 721 and into the sixth conveying section 723, and then transported by the sixth conveying section 723 through the third cargo inlet / outlet to the second lifting platform 22, thus realizing the transport of the product 8 from the second building to the first building. It should be noted that the second lifting mechanism can perform the lifting action simultaneously with the second shuttle bus 5 entering the second shuttle area 73, or it can perform the lifting action after the second shuttle bus 5 has fully entered the second shuttle area 73.

[0058] Conversely, when the product 8 to be transported is moved from the first building to the second building, it enters the sixth conveyor section 723 from the second lifting platform 22 under the transport of the second conveyor 23, and then enters the fourth conveyor section 721 and the fifth conveyor section 722 under the action of the sixth conveyor section 723. At this time, the second shuttle vehicle 5 is parked in the second connecting area 73. The second lifting mechanism of the second shuttle vehicle 5 rises to support the product 8 to be transported and to remove the product 8 from the fourth conveyor section 721 and the fifth conveyor section 722. Then, the second shuttle vehicle 5 drives to the storage area of ​​the second building to complete the transport of the product 8. It should be noted that the second lifting mechanism of the second shuttle vehicle 5 can perform the lifting action after the product 8 to be transported has completely entered the fourth conveyor section 721 and the fifth conveyor section 722.

[0059] In some embodiments, the fifth frame 711, the sixth frame 712, the seventh frame 713, and the eighth frame 714 are all metal frames. The fourth conveyor section 721, the fifth conveyor section 722, and the sixth conveyor section 723 are all roller conveyors.

[0060] In some embodiments, the width of the product 8 to be transported is greater than the distance between the seventh frame 713 and the eighth frame 714, but less than the distance between the fifth frame 711 and the sixth frame 712. The width of the second lifting mechanism on the second shuttle vehicle 5 is less than or equal to the distance between the seventh frame 713 and the eighth frame 714, so that the second shuttle vehicle 5 can drive into the second shuttle area 73. By ensuring that the center of gravity of the product 8 to be transported is located on the axis of the second shuttle vehicle 5, stable transport of the product 8 can be ensured, preventing the product 8 from falling off the second shuttle vehicle 5.

[0061] In some embodiments, the upper surface of the second shuttle vehicle 5 is provided with a second lifting mechanism, which is configured to place the product 8 to be transported. The second shuttle platform 7 is provided with a second sensor, which is signal-connected to the second lifting mechanism. The second sensor is configured to sense the position of the second shuttle vehicle 5 and drive the second lifting mechanism to perform a lowering action in response to the second shuttle vehicle 5 approaching the second shuttle area 73, and drive the second lifting mechanism to perform a lifting action in response to the second shuttle vehicle 5 moving away from the second shuttle area 73.

[0062] When the product 8 to be transported is transported from the second building to the first building, the second shuttle vehicle 5 transports the product 8 to the second shuttle area 73. When the second sensor senses that the second shuttle vehicle 5 is approaching the second shuttle area 73, the second sensor can send a third sensing signal to the central control mechanism. The central control mechanism can drive the second lifting mechanism to perform a lowering action based on the third sensing signal, so that the height of the product 8 to be transported decreases and it can fall into the fourth conveying section 721 and the fifth conveying section 722. Under the conveying of the fourth conveying section 721 and the fifth conveying section 722, it enters the sixth conveying section 723. Then, under the conveying of the sixth conveying section 723, it is transported through the third cargo inlet and outlet to the second lifting platform 22, thereby realizing the transport of the product 8 from the second building to the first building. After the second shuttle vehicle 5 completes one transport, it will leave the second shuttle area 73. At this time, the second sensor senses that the second shuttle area 73 is far away from the second shuttle area 73 and can send a fourth sensing signal to the central control mechanism. The central control mechanism can drive the second lifting mechanism to lift based on the fourth sensing signal so that the upper surface of the second shuttle vehicle 5 is at a suitable height for subsequent loading.

[0063] When the product 8 to be transported is transported from the first building to the second building, it enters the sixth transport section 723 from the second lifting platform 22 under the transport of the second transport component 23, and then enters the fourth transport section 721 and the fifth transport section 722 under the action of the sixth transport section 723. During this process, the second shuttle vehicle 5 also moves towards the second shuttle area 73. When the second sensor senses that the second shuttle vehicle 5 is approaching the second shuttle area 73, the second sensor can send a third sensing signal to the central control mechanism. The central control mechanism can drive the second lifting mechanism to perform a lowering action based on the third sensing signal, so that the upper surface of the second lifting mechanism is flush with the lower surface of the product 8 to be transported, so that the product 8 to be transported can be supported by the second shuttle vehicle 5. Once the product 8 to be transported is completely located in the second shuttle vehicle 5, the second shuttle vehicle 5 will leave the second shuttle area 73. At this time, the second sensor senses that the second shuttle area 73 is far away from the second shuttle area 73 and can send a fourth sensing signal to the central control mechanism. The central control mechanism can drive the second lifting mechanism to perform a lifting action based on the fourth sensing signal, so that the second lifting mechanism lifts the product 8 to be transported, so that the product 8 to be transported is separated from the fourth conveying section 721 and the fifth conveying section 722, and the product 8 to be transported can be transported to the storage area of ​​the second building under the transportation of the second shuttle vehicle 5.

[0064] In some embodiments, the transport device further includes a central control mechanism, which is signal-connected to the first lifting mechanism 1, the second lifting mechanism 2, the first connecting vehicle 4, the second connecting vehicle 5, and the conveying mechanism 3; wherein, the central control mechanism is configured to, in response to the transport device failing to transport the product 8 to be transported for a preset time, drive the first lifting mechanism 1, the second lifting mechanism 2, the first connecting vehicle 4, the second connecting vehicle 5, and the conveying mechanism 3 to stop working, or switch the first lifting mechanism 1, the second lifting mechanism 2, the first connecting vehicle 4, the second connecting vehicle 5, and the conveying mechanism 3 to a low-power standby mode.

[0065] Understandably, automated conveying is achieved by controlling the first lifting mechanism 1, the second lifting mechanism 2, the first connecting vehicle 4, the second connecting vehicle 5, and the conveying mechanism 3 through a central control mechanism. Furthermore, if the product 8 to be conveyed is not transported within a preset time, the central control mechanism can either stop the operation of the first lifting mechanism 1, the second lifting mechanism 2, the first connecting vehicle 4, the second connecting vehicle 5, and the conveying mechanism 3, or switch them to a low-power standby mode. This reduces energy consumption and saves transportation costs.

[0066] The central control unit may include a memory, in which preset time parameters can be stored. The preset time can be reasonably selected based on the transported products, transport rhythm, etc., for example, the preset time can be set to 10 minutes.

[0067] When the transport device switches to low-power standby mode, the first conveyor 13 of the first lifting mechanism 1, the second conveyor 23 of the second lifting mechanism 2, the conveying mechanism 3, the first shuttle vehicle 4, and the second shuttle vehicle 5 all operate at a low conveying speed. Alternatively, the first conveyor 13 of the first lifting mechanism 1, the second conveyor 23 of the second lifting mechanism 2, and the conveying mechanism 3 all operate at a low conveying speed, and the first shuttle vehicle 4 and the second shuttle vehicle 5 return to their respective charging stations for charging.

[0068] When the transport device switches to low-power standby mode, if the transport of the product 8 to be transported is restarted, the central control mechanism will wake up the first lifting mechanism 1, the second lifting mechanism 2, the first connecting vehicle 4, the second connecting vehicle 5 and the transport mechanism 3, so that the first lifting mechanism 1, the second lifting mechanism 2, the first connecting vehicle 4, the second connecting vehicle 5 and the transport mechanism 3 can start working.

[0069] In some embodiments, the transport device may further include a sensor that can detect the product 8 to be transported. If the sensor does not detect the product 8 to be transported for a preset time, it indicates that the transport device has not transported the product 8 to be transported for the preset time. At this time, the sensor sends a signal to the central control mechanism, so that the central control mechanism drives the first lifting mechanism 1, the second lifting mechanism 2, the first connecting vehicle 4, the second connecting vehicle 5 and the transport mechanism 3 to stop working, or switches the first lifting mechanism 1, the second lifting mechanism 2, the first connecting vehicle 4, the second connecting vehicle 5 and the transport mechanism 3 to a low-power standby mode.

[0070] In some embodiments, the central control mechanism includes a programmable logic controller (PLC). The PLC can be installed in the electrical cabinets of the first and second buildings and can be connected to the first lifting mechanism 1, the second lifting mechanism 2, the first shuttle vehicle 4, the second shuttle vehicle 5, and the conveying mechanism 3 via a bus network.

[0071] In some embodiments, the central control mechanism further includes a warehouse control system. The warehouse control system is deployed on a central server and can be connected to a programmable logic controller via a 5G communication network, or directly connected to the first lifting mechanism 1, the second lifting mechanism 2, the first shuttle vehicle 4, the second shuttle vehicle 5, and the conveying mechanism 3 via a 5G communication network.

[0072] In some embodiments, the transport device further includes a safety light curtain. At least one of the first connecting platform 6, the first lifting mechanism 1, the second connecting platform 7, and the second lifting mechanism 2 is provided with a safety light curtain. The safety light curtain is signal-connected to the central control mechanism and is configured to output a stop signal to the central control mechanism in response to its light beam being blocked, so that the central control mechanism drives the first lifting mechanism 1, the second lifting mechanism 2, the first connecting vehicle 4, the second connecting vehicle 5, and the conveying mechanism 3 to stop working.

[0073] It is understandable that by setting a safety light curtain in at least one of the first connecting platform 6, the first lifting mechanism 1, the second connecting platform 7, and the second lifting mechanism 2, when the beam of the safety light curtain is blocked, it is usually determined that a person has intruded into the transport area. At this time, in order to avoid the transport device causing harm to the intruder during the transport process, the first lifting mechanism 1, the second lifting mechanism 2, the first connecting vehicle 4, the second connecting vehicle 5, and the conveying mechanism 3 can be stopped by the control mechanism.

[0074] In some embodiments, the first connecting platform 6, the first lifting mechanism 1, the second connecting platform 7, and the second lifting mechanism 2 are all equipped with safety light curtains. The safety light curtains emit light, which can be received by a matching receiver. When there is intrusion between the safety light curtain and the receiver, the light from the safety light curtain will not be able to reach the receiver. At this time, the safety light curtain and / or the receiver can send a signal to the central control mechanism, causing the central control mechanism to stop the operation of the first lifting mechanism 1, the second lifting mechanism 2, the first connecting vehicle 4, the second connecting vehicle 5, and the conveying mechanism 3.

[0075] In some embodiments, the transport device further includes an alarm mechanism and a stop button. The alarm mechanism is signal-connected to the central control mechanism. When the central control mechanism receives a stop signal, it sends an alarm signal to the alarm mechanism, thereby triggering an audible and visual alarm. After receiving the audible and visual alarm information, the operator can press the stop button to stop the first lifting mechanism 1, the second lifting mechanism 2, the first shuttle vehicle 4, the second shuttle vehicle 5, and the conveying mechanism 3.

[0076] In some embodiments, the conveying mechanism 3 includes a connecting corridor 31, a rainproof layer 32 connected to the connecting corridor 31, and a conveying platform 33 disposed on the connecting corridor 31. The connecting corridor 31 is provided with a third sensor and a fourth sensor, both of which are signal-connected to the conveying platform 33. The third sensor is used to sense the position of the first lifting platform 12 and, in response to the first lifting platform 12 being at a second height, drives the conveying platform 33 to start conveying. The fourth sensor is used to sense the position of the product 8 to be conveyed and, in response to the product 8 to be conveyed entering the second lifting platform 22 from the conveying platform 33, drives the conveying platform 33 to stop conveying. Alternatively, the third sensor is used to sense the position of the second lifting platform 22 and, in response to the second lifting platform 22 being at a second height, drives the conveying platform 33 to start conveying. The fourth sensor is used to sense the position of the product 8 to be conveyed and, in response to the product 8 to be conveyed entering the first lifting platform 12 from the conveying platform 33, drives the conveying platform 33 to stop conveying.

[0077] It is understandable that a conveyor platform 33 is installed on the connecting corridor 31 to achieve horizontal conveying of the products 8 to be conveyed. The conveyor platform 33 includes roller conveyors, conveyor belts, etc. A rainproof layer 32 is installed on the connecting corridor 31 so that the conveying of the conveyor platform 33 is not affected by external weather, and the conveying of the conveyor platform 33 can be achieved even in severe weather such as heavy rain, heavy snow, and strong winds.

[0078] When the product 8 to be transported is moved from the first building to the second building, it can enter the conveyor platform 33 from the first lifting platform 12. After the first lifting platform 12 rises from the first height to the second height, the third sensor sends a sensing signal to the central control mechanism, which then drives the conveyor platform 33 to begin transporting the product 8. This allows the product 8 to be transported from the first lifting platform 12 to the conveyor platform 33, and then to the second lifting platform 22. When the fourth sensor detects that the product 8 has entered the second lifting platform 22, it drives the conveyor platform 33 to stop transporting, thereby reducing the energy consumption of the conveyor platform 33.

[0079] When the product 8 to be transported is moved from the second building to the first building, it can enter the conveyor platform 33 from the second lifting platform 22. After the second lifting platform 22 rises from the first height to the second height, the third sensor sends a sensing signal to the central control mechanism, which then drives the conveyor platform 33 to begin transporting the product 8. This allows the product 8 to be transported from the second lifting platform 22 to the conveyor platform 33, and then from the conveyor platform 33 to the first lifting platform 12. When the fourth sensor detects that the product 8 has entered the first lifting platform 12, it drives the conveyor platform 33 to stop transporting, thereby reducing the energy consumption of the conveyor platform 33.
