Description

Technical Field

[0001] This utility model relates to the technical field of warehouse robots, and in particular to a heavy cargo warehouse robot. Background Technology

[0002] Warehouse robots are now widely used in warehousing for handling goods. For example, Chinese utility model patent CN220844311U discloses a logistics warehousing and handling robot. This robot includes a device body, which comprises a base, a placement plate, a support plate, a top plate, a buffer assembly, a limiting assembly, and a connecting plate. The placement plate is connected to the upper end of the base via a pillar. The placement plate has support plates and connecting plates at both ends, and the top of the support plates and connecting plates is fixedly connected to the upper end of the top of the top of the support plates and connecting plates. A limiting assembly is provided on one side of the support plates and connecting plates. The limiting assembly includes a slide, a drive motor, a lead screw, a slider, a connecting rod, a fixing block, a guide column, a first damper, a first buffer spring, and a limiting plate. This logistics warehousing and handling robot effectively fixes and limits the stored goods through the setting of the limiting assembly, avoiding collisions that could damage the stored goods during handling and transportation, thereby further improving the safety of the stored goods.

[0003] However, the aforementioned warehouse robots, due to their frame structure erected on the base plate and their lightweight wheels, are inconvenient for handling heavy and large goods. Therefore, proposing a heavy-duty warehouse robot would be practical. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a heavy cargo storage robot that can lift and transport heavy goods. By setting heavy-duty wheels with independently adjustable angles, the robot can move flexibly and has good practicality.

[0005] This utility model discloses a heavy-duty cargo storage robot, comprising a platform and multiple heavy-duty wheels; it also includes multiple angle adjustment mechanisms, push cylinders, pallets, pick-and-place mechanisms, and supports. Four heavy-duty wheels and four angle adjustment mechanisms are provided. The four heavy-duty wheels are respectively mounted on the lower end surface of the platform via four angle adjustment mechanisms, and are arranged in a rectangular pattern. The fixed end of the push cylinder is mounted on the platform, and the pallet is horizontally mounted on the piston rod of the push cylinder. The pick-and-place mechanism is mounted on the platform and is used for loading and placing supports, which in turn support heavy cargo. During operation, the supports are loaded onto the pick-and-place mechanism, the four heavy-duty wheels rotate to drive the platform to move, and the four angle adjustment mechanisms adjust the four heavy-duty wheels respectively. The tilt angle of the wheels allows the platform to turn, translate, and rotate, bringing it to the bottom of heavy goods. The piston rod of the push cylinder extends, raising the pallet and lifting the heavy goods. The four heavy-duty wheels rotate, moving the platform to the designated position in the warehouse. Once there, the pick-and-place mechanism places the support column on the ground, retracts, and the piston rod of the push cylinder retracts, lowering the pallet and placing the heavy goods on the support column. Four angle-adjusting mechanisms adjust the angles of the four heavy-duty wheels, moving the platform beyond the bottom of the heavy goods to continue transporting other heavy goods. This efficient and practical method ensures effective handling of heavy cargo.

[0006] Preferably, it also includes multiple slide rods, which are slidably inserted into the platform and connected at their upper ends to the tray; the multiple slide rods limit the lifting and lowering of the tray, thereby improving the stability of the tray.

[0007] Preferably, the angle adjustment mechanism includes a thrust bearing disc, a wheel frame, a motor, and a rotating assembly. The thrust bearing disc is mounted on the lower end face of the platform, the wheel frame is mounted on the rotating end of the thrust bearing disc, and the heavy-duty wheel is rotatably mounted on the wheel frame. The heavy-duty wheel is located in the center inside the thrust bearing disc. The motor is mounted on the wheel frame, and the output shaft of the motor is connected to the heavy-duty wheel for transmission. The rotating assembly drives the rotating end of the thrust bearing disc to rotate, which in turn drives the wheel frame to rotate, causing the wheel frame to adjust the orientation angle of the heavy-duty wheel. The motor drives the heavy-duty wheel to rotate, thereby realizing the driving and angle adjustment of the heavy-duty wheel. The thrust bearing disc improves the load-bearing capacity and provides a wide range of angle adjustment, making it highly practical.

[0008] Preferably, the rotating assembly includes a worm gear, a worm, and a second motor. The worm gear is concentrically mounted on the rotating end of the thrust bearing disk. The worm is mounted on the platform via a bracket and meshes with the worm gear. The second motor is mounted on the platform, and its output shaft is connected to the worm gear via a transmission connection. The second motor drives the worm to rotate, causing the worm to mesh with the worm gear and drive the rotating end of the thrust bearing disk and the wheel frame to rotate, thereby adjusting the angle of the heavy-duty wheel. The self-locking function of the worm gear and worm makes the angle adjustment of the heavy-duty wheel more stable.

[0009] Preferably, the pick-and-place mechanism includes a robotic arm, an electromagnetic block, a rack, a motor, and gears. The robotic arm is slidably mounted on the platform, with its outer end extending beyond the platform. An electromagnetic block is mounted on the outer end of the robotic arm for attracting and releasing the support column. The robotic arm is arranged at an angle, with its outer end lower than its inner end. The motor is mounted on the platform, and a gear is concentrically mounted on the output shaft of the motor, meshing with the rack. The motor drives the gear to rotate, and the gear meshes with the rack to drive the robotic arm to extend beyond or retract into the platform. When the robotic arm extends, it places the support column outside the platform via the electromagnetic block. When the robotic arm retracts, it lifts the support column and places it against the edge of the platform via the electromagnetic block, facilitating the placement and retraction of the support column.

[0010] Preferably, it also includes a control box and a camera. The control box is installed on the platform, and the camera is installed on the control box. The camera installed on the control box monitors the environment, which improves the hardware foundation for visual-assisted obstacle avoidance and automatic driving, and improves the reliability of the platform's movement.

[0011] Preferably, it also includes a communication module, which is installed on the control box; multiple control boxes are connected to a local network through multiple communication modules, so that after sending a handling command to one robot, multiple networked warehouse robots can cooperate with each other through multiple communication modules to handle large and heavy goods, thereby improving handling efficiency.

[0012] Compared with the prior art, the advantages of this utility model are that it can lift and transport heavy goods, and the robot can move flexibly by setting heavy wheels with independently adjustable angles, which makes it highly practical. Attached Figure Description

[0021] To facilitate understanding of this utility model, a more complete description will be given below with reference to the accompanying drawings. This utility model can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to make the disclosure of this utility model more thorough and complete. Example 1

[0022] like Figure 1 , Figure 2 , Figure 3 and Figure 7 As shown, a heavy-duty cargo storage robot includes a platform 1 and multiple heavy-duty wheels 2; it also includes multiple angle adjustment mechanisms 3, push cylinders 4, pallets 5, pick-and-place handles 6, and support columns 7. Four heavy-duty wheels 2 and four angle adjustment mechanisms 3 are provided. The four heavy-duty wheels 2 are respectively mounted on the lower end surface of the platform 1 through the four angle adjustment mechanisms 3. The four heavy-duty wheels 2 are arranged in a rectangular pattern. The fixed end of the push cylinder 4 is mounted on the platform 1. The pallet 5 is horizontally mounted on the piston rod of the push cylinder 4. The pick-and-place handles 6 are mounted on the platform 1 and are used for loading and placing the support columns 7, which are used to support heavy cargo. It also includes multiple sliding rods 8. Multiple sliding rods 8 are slidably inserted on platform 1, and the upper ends of the multiple sliding rods 8 are connected to the support plate 5; the pick-and-place handle 6 includes a robotic arm 15, an electromagnetic block 16, a rack 17, a motor 18, and a gear 19. The robotic arm 15 is slidably installed on platform 1, and the outer end of the robotic arm 15 extends outside the platform 1. The electromagnetic block 16 is installed on the outer end of the robotic arm 15. The electromagnetic block 16 is used to attract and release the support column 7. The robotic arm 15 is arranged at an angle, and the outer end of the robotic arm 15 is lower than the inner end. The motor 18 is installed on platform 1, and the output shaft of the motor 18 is concentrically mounted with the gear 19. The gear 19 meshes with the rack 17.

[0023] During operation, the support column 7 is loaded onto the pick-and-place handle 6. The four heavy-duty wheels 2 rotate, driving the platform 1 to move. The four angle adjustment mechanisms 3 adjust the tilt angle of the four heavy-duty wheels 2 respectively, thereby enabling the platform 1 to perform turning, translation, and rotation operations. When the platform 1 reaches the bottom of the heavy goods, the piston rod of the push cylinder 4 extends, pushing the pallet 5 to rise. Multiple sliding rods 8 limit the raising and lowering of the pallet 5, allowing the pallet 5 to lift the heavy goods. The rotation of the four heavy-duty wheels 2 drives the platform 1 to move to the designated position. After reaching the designated position in the warehouse, the motor 3 18 drives the gear 19 to rotate. The mechanism involves gear 19 meshing with rack 17 to drive robotic arm 15 to extend from platform 1. Electromagnetic block 16 places support column 7 onto the ground outside platform 1. Motor 3 18 drives gear 19 to rotate, and gear 19 meshes with rack 17 to drive robotic arm 15 back onto platform 1. The piston rod of push cylinder 4 retracts, causing pallet 5 to descend, allowing heavy goods to be placed on support column 7. Four angle adjustment mechanisms 3 adjust the angles of four heavy-duty wheels 2, causing platform 1 to move out of the bottom of the heavy goods, allowing for the continued transport of other heavy goods. This achieves effective handling of heavy goods and is highly practical. Example 2

[0024] like Figure 3 , Figure 5 and Figure 6 As shown, based on Embodiment 1, the angle adjustment mechanism 3 includes a thrust bearing disk 9, a wheel frame 10, a motor 11, and a rotating assembly. The thrust bearing disk 9 is mounted on the lower end face of the platform 1. The wheel frame 10 is mounted on the rotating end of the thrust bearing disk 9. The heavy-duty wheel 2 is rotatably mounted on the wheel frame 10. The heavy-duty wheel 2 is located in the center inside the thrust bearing disk 9. The motor 11 is mounted on the wheel frame 10. The output shaft of the motor 11 is connected to the heavy-duty wheel 2. The rotating assembly drives the rotating end of the thrust bearing disk 9 to rotate. The rotating assembly includes a worm gear 12, a worm 13, and a motor 14. The worm gear 12 is concentrically mounted on the rotating end of the thrust bearing disk 9. The worm 13 is mounted on the platform 1 through a bracket. The worm 13 meshes with the worm gear 12. The motor 14 is mounted on the platform 1. The output shaft of the motor 14 is connected to the worm 13.

[0025] Motor 2 14 drives worm 13 to rotate, which in turn meshes with worm wheel 12 to drive the rotating end of thrust bearing disk 9 and wheel frame 10 to rotate. This causes wheel frame 10 to drive heavy wheel 2 to adjust its orientation angle. Motor 11 drives heavy wheel 2 to rotate, thus realizing the driving and angle adjustment of heavy wheel 2. The thrust bearing disk 9 improves the load-bearing capacity and has a wide adjustment angle range, making it highly practical. Example 3

[0026] like Figure 1 , Figure 2 and Figure 4As shown, based on Embodiment 1, it also includes a control box 20 and a camera 21. The control box 20 is installed on the platform 1, and the camera 21 is installed on the control box 20. It also includes a communication module 22, which is installed on the control box 20.

[0027] The camera 21 installed on the control box 20 monitors the environment, providing a hardware foundation for visual-assisted obstacle avoidance and automatic driving, and improving the reliability of the platform 1's movement. Multiple control boxes 20 are connected to a local network through multiple communication modules 22, providing a hardware foundation for multiple robots to work together in a network. Thus, after sending a handling command to one robot, multiple networked warehouse robots can cooperate with each other through multiple communication modules 22 to handle large and heavy goods, improving handling efficiency.

[0028] like Figures 1 to 7 As shown, this utility model discloses a heavy cargo warehousing robot. During operation, the support column 7 is first loaded onto the electromagnetic block 16. Four heavy-duty wheels 2 rotate, driving the platform 1 to move. Four angle-adjusting mechanisms 3 adjust the tilt angles of the four heavy-duty wheels 2, enabling the platform 1 to perform turning, translation, and rotation operations, allowing the platform 1 to reach the bottom of the heavy cargo. Then, the piston rod of the push cylinder 4 extends, pushing the pallet 5 to rise, lifting the heavy cargo. The four heavy-duty wheels 2 rotate, moving the platform 1 to the designated position within the warehouse. Then, motor 3 18 drives gear 19 to rotate, and gear 19 meshes with rack 1. The robotic arm 15 extends out of the platform 1, the electromagnetic block 16 places the support column 7 outside the platform 1, the robotic arm 15 retracts and resets, the piston rod of the push cylinder 4 retracts to lower the pallet 5, so that the heavy goods are placed on the support column 7, the four angle adjustment mechanisms 3 adjust the angle of the four heavy wheels 2, so that the platform 1 moves out of the bottom of the heavy goods, and continues to transport other heavy goods; finally, multiple control boxes 20 are connected to a local network through multiple communication modules 22, so that after sending a handling command to one robot, multiple networked warehouse robots can cooperate with each other through multiple communication modules 22 to transport large heavy goods.
