Description

Technical Field

[0001] The present invention relates to a cargo handling device, in particular to an intelligent cargo handling device based on Internet of Things control, and belongs to the technical field of cargo handling. Background Art

[0002] Intelligent cargo handling devices primarily rely on batteries for power. When controlled manually using the Internet of Things, they can automatically complete handling tasks without human intervention, demonstrating a high level of flexibility, intelligence, and automation. They can flexibly change paths based on material location and production process changes. Compared to traditional manual handling and conveyor belts, these devices offer lower cost changes. As a key tool in intelligent warehousing, they are instrumental in shortening material handling times and reducing the space occupied by materials.

[0003] The intelligent cargo handling device in the existing technology is generally an intelligent mobile robot, namely an AGV cart. The AGV cart can realize intelligent and unmanned logistics transportation from material warehousing to production line and then to finished product warehousing and shipment. It has the characteristics of high positioning accuracy, strong practicality and flexible transportation methods. However, in actual use, the AGV cart has no mechanism on its top to fix the cargo. When the AGV cart carries cargo with a higher height and encounters other obstacles when turning, the AGV cart can brake immediately to avoid collision with the obstacle, but the cargo on the top of the AGV cart will shake due to inertia, or even fall, making it impossible for the AGV cart to effectively ensure the safety of the cargo during the cargo transportation process, reducing the practicality of the AGV cart.

[0014] Optionally, the second limiting mechanism includes two rotating frames, which are rotatably mounted on two opposite outer walls of the base plate, and two extension plates are movably mounted inside one end of the two rotating frames away from the base plate.

[0015] Optionally, a limit plate is installed at one end of the two extension plates away from the rotating frame, and a groove adapted to the limit plate is formed on the top of the top plate.

[0016] The beneficial effects of the present invention are:

[0017] 1. In the present invention, when the device is used to transport goods of higher height, after the goods are placed on the top of the two movable plates, the driving mechanism preset in the device can drive the multiple rotating blocks to drive the multiple first limit rods and the second limit rods to rotate upward to a vertical state, and then the extension length of the multiple electric telescopic rods can be adjusted according to the height of the goods, so that the bottoms of the multiple first limit rods and the second limit rods can abut against the top of the goods, and then the positions of the multiple first limit rods and the second limit rods can be adjusted by the multiple second electric sliders, so that the multiple first limit rods and the second limit rods can be located at the four corners of the goods to fix the goods, so that when the device is driving the goods to move, even if an emergency occurs, the stability of the goods on its top can be guaranteed, thereby ensuring the safety of the goods during transportation.

The device can be manually pushed to move the device to other locations for temporary storage to avoid affecting the subsequent movement of other devices.

[0020] 4. In this invention, when large shelves need to be transported, multiple first limit mechanisms can be adjusted to be located on both sides of the two movable plates, so that there are no other components above the device, which facilitates the device to move to the bottom of the shelf to transport the shelf; and the distance between the two movable plates can be adjusted by the position of the first electric slider at the bottom in the first slide groove, so that the device can transport shelves of different sizes, thereby improving the applicability of the device.

DETAILED DESCRIPTION

[0032] The technical solutions of the present invention will be clearly and completely described below with reference to the embodiments. Obviously, the embodiments described are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts shall fall within the scope of protection of the present invention.

[0033] Reference Figures 1-9, an intelligent cargo handling device based on Internet of Things control, includes a bottom plate 1 and a top plate 21, the bottom plate 1 and the top plate 21 are connected by a lifting frame 2, two movable plates 3 are installed on the top of the top plate 21, and the outer walls on both sides away from each other of the two movable plates 3 are installed with a first limiting mechanism for fixing the cargo, the first limiting mechanism includes multiple fixed plates 5, and the sides of the multiple fixed plates 5 away from the movable plates 3 are each installed with a first limiting rod 6 and a second limiting rod 18, and the outer walls on both sides opposite to each other of the bottom plate 1 are each installed with a second limiting mechanism for fixing the position of the lifting frame 2.

[0034] As a technical optimization solution of the present invention, two first chutes 22 are provided on the top of the top plate 21, and two first electric sliders 24 are installed inside the two first chutes 22. The bottoms of the two movable plates 3 are respectively connected to the tops of the two adjacent first electric sliders 24. When the device is needed to transport items such as shelves, the staff can control the device through the Internet of Things, so that the device can be moved to the bottom of the shelf through the multiple movable wheels at the bottom of the bottom plate 1, and the height of the lifting frame 2 is adjusted. After the tops of the two movable plates 3 are brought into contact with the bottom of the shelf, the shelf is pushed upward again for a distance so that the shelf is separated from the ground, and the device can drive the shelf for transportation; and both movable plates 3 can move back and forth in the first chutes 22 through the first electric sliders 24 installed at the bottom, so that the distance between the two movable plates 3 can be adjusted, which is convenient for transporting shelves of different widths.

[0035] As a technical optimization solution of the present invention, a second sliding groove 12 is provided on the outer wall of the two movable plates 3 away from each other, and two second electric sliders 13 are installed inside the two second sliding grooves 12. The outer wall of the two groups of second electric sliders 13 away from the movable plate 3 is rotatably installed with a rotating block 9.

[0036] As a technical optimization solution of the present invention, the outer walls of the two groups of rotating blocks 9 close to the fixed plate 5 are hinged with mounting plates 25, and the outer walls of the multiple mounting plates 25 close to the fixed plate 5 are all installed with electric telescopic rods 4.

[0037] As a technical optimization solution of the present invention, a third sliding groove 14 is opened on the outer wall of one side of multiple fixed plates 5 close to the electric telescopic rod 4, and a movable block 19 is installed at the protruding end of each of the multiple electric telescopic rods 4. The multiple movable blocks 19 can move back and forth in the third sliding groove 14.

[0038] As a technical optimization solution of the present invention, two fixed blocks 15 are installed on the outer wall of one side of multiple fixed plates 5 away from the movable plate 3, and the end of the movable block 19 close to the fixed block 15 extends to the outside of the third slide groove 14. The two fixed blocks 15 can be threadedly connected to the end of the movable block 19 located outside the third slide groove 14 through a limiting bolt 16.

[0039] As a technical optimization solution of the present invention, a fourth slide groove 17 is opened on the outer wall of the side opposite to the third slide groove 14 of multiple fixed plates 5, and two third electric sliders 20 are installed in the multiple fourth slide grooves 17, one of the third electric sliders 20 is connected to the first limit rod 6, and the other third electric slider 20 is rotatably connected to the second limit rod 18.

[0040] As a technical optimization solution of the present invention, an extension rod 11 is movably installed inside the first limit rod 6 and the second limit rod 18, and a roller 7 is installed on the outer wall of the first limit rod 6 and the second limit rod 18 on the side away from the fixed plate 5. When using the device to transport goods of higher height, the distance between the two movable plates 3 can be adjusted according to the size of the goods. After the goods are placed on the top of the two movable plates 3, in order to ensure the stability of the device during the goods transportation process, the movable blocks 19 at the extended ends of the multiple electric telescopic rods 4 can be slid to the center position of the third slide groove 14, so that the movable blocks 19 and the fixed blocks 15 at the center position of the outer wall of the fixed plate 5 are in the same straight line. Then, after locking the movable blocks 19 and the fixed blocks 15 through multiple limit bolts 16, the extended ends of the multiple electric telescopic rods 4 can be controlled to be in an extended state. Then, the multiple rotating blocks 9 are driven to rotate upward 90 degrees by the preset driving mechanism in the device, driving the multiple electric telescopic rods 4, the fixed plate 5, the first limit rod 6 and the second limit rod 18 to rotate upward 90 degrees. The positioning rod 6 and the second limiting rod 18 rotate upward synchronously. At this time, the multiple first limiting rods 6 and the second limiting rod 18 will be in a horizontal state above the cargo. Then, the extended ends of the multiple electric telescopic rods 4 are controlled to retract a distance so that the bottoms of the multiple first limiting rods 6 and the second limiting rod 18 are in contact with the top of the cargo. Finally, the multiple second electric sliders 13 are controlled to slide in the second slide groove 12, driving the rotating block 9, the electric telescopic rod 4, the fixed plate 5, the first limiting rod 6 and the second limiting rod 18 to move synchronously, so that the multiple first limiting rods 6 and the second limiting rod 18 can be respectively located at the four corner positions of the top of the cargo, so that the position of the cargo on the top of the two movable plates 3 can be limited and fixed, ensuring the safety of the device in the process of transporting cargo with higher heights.

[0041] When the device is transporting goods, if the moving wheels at the bottom of the base plate 1 are entangled with debris, the forward movement of the moving wheels is blocked, and the device cannot continue to drive the goods to move, the driving mechanism can drive two of the mounting plates 25 that are not on the same moving plate 3 to rotate downward 90 degrees, and drive the electric telescopic rod 4, the fixed plate 5, the first limiting rod 6 and the second limiting rod 18 to rotate downward together, while the positions of the other two mounting plates 25 remain unchanged, so that the other two groups of the first limiting rod 6 and the second limiting rod 18 can continue to limit and fix the goods, ensuring that the stability of the goods is not affected. After the trolley is turned downward, it is flush with the ground and can contact the ground. Then, the extended ends of the two electric telescopic rods 4 in the downward vertical state can be controlled to extend. The device will be moved upward for a distance by the reaction force of the two electric telescopic rods 4 in the extended state. The moving wheels at the bottom of the base plate 1 are separated from the ground. The staff can manually clean the debris wrapped around the surface of the moving wheels at this time. After cleaning, the extended ends of the two electric telescopic rods 4 are controlled to retract and return to their original position, so that the moving wheels can contact the ground again, so that the device can continue to carry the goods, avoiding the reduction of the efficiency of the goods carrying work. Even in the process of the device carrying goods, the device may not be able to move due to inappropriate When a fault causes damage or a mobile wheel fails, making it impossible to continue to transport goods, in order not to affect the subsequent movement of other devices, the staff needs to promptly transfer the device with the problem to another location for maintenance. However, the mobile wheel cannot continue to move forward, and the staff cannot push the heavy devices and goods. At this time, the driving mechanism can be used to drive two mounting plates 25 that are not on the same mobile plate 3 to rotate downward 90 degrees, and drive the electric telescopic rod 4, the fixed plate 5, the first limit rod 6 and the second limit rod 18 to rotate downward together. Since rollers 7 are provided on the tops of the first limit rod 6 and the second limit rod 18, After the two sets of first limiting rods 6 and second limiting rods 18 are rotated downward by 90 degrees, the rollers 7 on their tops can all contact the ground, and then the protruding ends of the two electric telescopic rods 4 are extended to push the device upward to drive the moving wheels to separate from the ground, so that the device at this time is supported by the two sets of first limiting rods 6 and second limiting rods 18 and multiple rollers 7. The staff can use the rollers 7 to move the device and the goods on its top to other locations for temporary storage. After the subsequent cargo handling work is completed, the faulty device can be repaired to avoid the problem that damage to the device not only affects its own handling but also affects the use of other devices.

[0042] When the stacking rack and the goods stacked on top need to be transported as a whole, the device cannot enter the bottom of the stacking rack due to the narrow space at the bottom of the stacking rack. At this time, one of the mounting plates 25 can be controlled to rotate downward 90 degrees, driving the electric telescopic rod 4, the fixing plate 5, the first limit rod 6 and the second limit rod 18 to rotate downward together, so that the multiple rollers 7 are in contact with the ground, and then the extension rods 11 inside the first limit rod 6 and the second limit rod 18 are controlled to be in an extended state. According to the spacing of the gap at the bottom of the stacking rack, the spacing between the two third electric sliders 20 is adjusted in the fourth slide slot 17, driving the first limit rod 6 and the second limit rod 18 to be consistent with the gap width at the bottom of the stacking rack. At this time, the first limit rod 6 and the second limit rod 18 and the two extended extension rods 11 can be used as forks. After the device drives the two extension rods 11, the first limit rod 6 and the second limit rod 18 to be inserted into the bottom gap of the stacking rack, the lifting frame 2 is used to lift the goods. When the load shears are lifted, the two lifting plates 11 and the second lifting plates 18 are lifted and lowered, and the load shears are lifted and lowered, so that the load shears are lifted and lowered.

[0043] When the staff in the warehouse need to take the goods on the top of the shelf or need to repair other equipment, and the automatic lifting equipment is damaged and cannot be used, the device itself is equipped with a lifting frame 2, so that the device can be temporarily used as an automatic lifting equipment. The staff can stand on the top of the two movable plates 3 and move upward with the help of the lifting frame 2. At this time, the multiple first limit rods 6 and the second limit rods 18 located on the top of the two movable plates 3 can be used with the help of the multiple third electric sliders 20 to move in the fourth slide groove 17, the rotation of the two second limit rods 18 and the extension of the extension rods 11 inside the two rotated second limit rods 18 to form a fence to protect the staff standing on the top of the two movable plates 3, and the height of the fence can also be adjusted by the length of the extended ends of the multiple electric telescopic rods 4, which is convenient for protecting staff at different heights and improving the safety of staff using the device for climbing operations.

[0044] As a technical optimization solution of the present invention, the second limiting mechanism includes two rotating frames 10, which are respectively rotatably installed on the opposite outer walls of the base plate 1, and two extension plates are movably installed inside the ends of the two rotating frames 10 away from the base plate 1.

[0045] As a technical optimization solution of the present invention, a limit plate 8 is installed on the end of the two extension plates away from the rotating frame 10, and a groove 23 is provided on the top of the top plate 21 to match the limit plate 8. Through the second limit mechanism, when the device is transporting goods, the two rotating frames 10 that rotate upward and are in a vertical state can drive the two extension plates and the limit plate 8 inside them to rotate upward synchronously until the multiple limit plates 8 are moved into the groove 23 on the top of the top plate 21, and then the lifting frame 2 is limited and fixed, so as to prevent the lifting frame 2 from extending upward due to accidental touch by the staff during use, causing the goods to fall; and when the staff uses the device to perform high-altitude operations, the two rotating frames 10 will rotate downward, without the need to limit and fix the lifting frame 2, and rotate it downward to drive the limit plate 8 to contact the ground, thereby increasing the contact area between the device and the ground, thereby improving the stability of the device during use and better ensuring the safety of the staff.

[0046] In the present invention, when the user uses the device to transport items such as shelves, the user drives multiple rotating blocks 9 through the driving mechanism to drive multiple electric telescopic rods 4, fixed plates 5, first limit rods 6 and second limit rods 18 to rotate to the two sides of the two movable plates 3 respectively, and removes the limit bolts 16 on the outer walls of the multiple fixed plates 5, so that the multiple fixed plates 5 can drive the first limit rod 6 and the second limit rod 18 to move downward, and then the multiple limit bolts 16 pass through the fixed blocks 15 above the outer walls of the fixed plates 5 and are connected to the movable blocks 19, so that there is no obstruction of other components above the two movable plates 3. The staff can move to the bottom of the shelf through the Internet of Things control device, adjust the height of the lifting frame 2, drive the two movable plates 3 to push the shelf upward for a distance, so that the shelf is separated from the ground, and the device can drive the shelf for transportation.

[0047] When using the device to transport goods of higher height, after placing the goods on top of the two movable plates 3, the extended ends of the multiple electric telescopic rods 4 are controlled to be in an extended state, and then the multiple first limit rods 6 and second limit rods 18 are driven to rotate upward by the preset driving mechanism in the device, and then the extended ends of the multiple electric telescopic rods 4 are controlled to retract so that the bottoms of the multiple first limit rods 6 and second limit rods 18 are in contact with the top of the goods, so that the position of the goods on the top of the two movable plates 3 can be limited and fixed, ensuring the safety of the device in the process of transporting goods of higher height.

[0048] When the device is transporting goods, if debris appears to be entangled on the moving wheels at the bottom of the base plate 1, the forward movement of the moving wheels is blocked, and the device cannot continue to drive the goods to move, the driving mechanism can drive two of the mounting plates 25 that are not on the same moving plate 3 to rotate downward 90 degrees, driving the first limit rod 6 and the second limit rod 18 to rotate downward together and contact the ground, and control the extended ends of the two electric telescopic rods 4 in a downward vertical state to extend. The device will be moved upward for a distance by the reaction force of the two electric telescopic rods 4 in an extended state, and the moving wheels at the bottom of the base plate 1 will be separated from the ground. At this time, the staff can manually clean up the debris entangled on the surface of the moving wheels to avoid reducing the efficiency of cargo handling.

[0049] When it is necessary to move the stacking rack and the goods stacked on top of it as a whole, one of the mounting plates 25 is controlled to rotate downward 90 degrees to drive the first limit rod 6 and the second limit rod 18 to rotate downward, the two extension rods 11 are controlled to be in an extended state, and the distance between the first limit rod 6 and the second limit rod 18 is adjusted. At this time, the first limit rod 6 and the second limit rod 18 and the two extended extension rods 11 can be used as forks. After the first limit rod 6 and the second limit rod 18 are driven by the device to be inserted into the bottom gap of the stacking rack, the upward extension of the lifting frame 2 drives the stacking rack and the goods on top of it to be lifted upward, and the stacking rack and the goods on top of it are moved with the help of the movement of the device itself, which further improves the applicability of the device.

[0050] When the staff in the warehouse need to take the goods on the top of the shelf or need to inspect other equipment, the staff can stand on the top of the two movable plates 3 and move upward with the help of the lifting frame 2. At this time, the multiple first limit rods 6 and the second limit rods 18 located on the top of the two movable plates 3 can move in the fourth slide groove 17 with the help of multiple third electric sliders 20, the rotation of the two second limit rods 18 and the extension of the two rotated second limit rods 18 to form a fence to protect the staff standing on the top of the two movable plates 3, and the height of the fence can also be adjusted by the extension length of the extended ends of the multiple electric telescopic rods 4, which is convenient for protecting staff at different heights and improving the safety of staff using the device for climbing operations. When the staff use the device to climb operations, the two rotating frames 10 will drive the two limit plates 8 to rotate downward until they are in contact with the ground, thereby increasing the contact area between the device and the ground, thereby improving the stability of the device during use.
