Description
Technical Field
[0001] This utility model relates to the field of warehouse robot technology, and in particular to a warehouse robot with a lifting structure. Background Technology
[0002] Warehouse robots with lifting structures are mainly used for handling and storing goods. Their lifting structure allows them to lift goods to different heights. They can move between shelves, accurately reach the designated location according to system instructions, and use the lifting device to lift the goods to complete the storage and retrieval operations.
[0003] Currently, warehouse robots used for handling and storing goods typically employ forklifts to move and store goods in warehouses. Forklifts can move large quantities of goods from the unloading area to designated storage locations in a short time, or retrieve goods from the storage area and load them onto transport vehicles. Compared to manual handling, efficiency is significantly improved, greatly shortening handling time and increasing logistics turnover efficiency.
[0004] Although forklifts can move large quantities of goods from the unloading area to designated storage locations in a short time, the lifting range of the forks is strictly limited by the mast height. When faced with racks of different heights, especially rack layouts with large height differences, forklifts often have difficulty adapting flexibly. Therefore, warehouse robots with lifting structures are proposed to solve the above problems. Utility Model Content
[0005] To overcome the above shortcomings, this utility model provides a warehouse robot with a lifting structure, which aims to improve the problem that the existing technology cannot handle and store goods in the case of shelving layout with large height differences.
[0006] To achieve the above objectives, the present invention adopts the following technical solution:
[0007] A warehouse robot with a lifting structure includes a base and a placement plate. Lifting components are fixedly connected to both ends of the top of the base. A forward and backward moving component is provided at the bottom of the placement plate. A pushing component is provided on the inner side of the placement plate. A hollow plate is provided at the top of the placement plate. A driving component is provided on the inner side of the hollow plate. Positioning components are provided at both ends of the hollow plate.
[0008] The lifting assembly includes a support column, which is fixedly connected to the top of the base. A drive motor is fixedly connected to the outer side of one end of the support column. Both ends of the support column are rotatably connected to pulleys. The output end of the drive motor is fixedly connected to the inner side of one of the pulleys. Both pulleys are fitted with belts on their inner sides.
[0009] As a further description of the above technical solution:
[0010] The forward and backward moving assembly includes a connecting plate, which is fixedly connected to the outer side of the end of the placement plate. A housing is fixedly connected to the side of the connecting plate. Two gears are rotatably connected to the inner side of the housing. A second drive motor is fixedly connected to the top of the connecting plate. The output end of the second drive motor is fixedly connected to the inner side of one of the gears. Toothed blocks are slidably connected to the outer sides of both ends of the housing. The two gears are meshed with the outer sides of the two toothed blocks, and the two toothed blocks are slidably connected to the inner side of the connecting plate.
[0011] As a further description of the above technical solution:
[0012] The pushing component includes a pushing plate, which is fixedly connected to the ends of two toothed blocks, and the middle part of the pushing plate is slidably connected to the inner side of the placement plate.
[0013] As a further description of the above technical solution:
[0014] The drive assembly includes a dual-head motor, which is fixedly connected to the inner side of a hollow plate. The hollow plate is fixedly connected to the top of a push plate. Both ends of the hollow plate are fixedly connected to connecting shells. Worms are rotatably connected to the inner sides of both connecting shells. The output ends of the dual-head motor are fixedly connected to the ends of the two worms. Worm wheels are rotatably connected to the inner sides of both connecting shells. The two worm wheels are meshed with the outer sides of the two worms.

The outer side of the end of the electric push rod is fixedly connected to the inner side of the worm gear, and a fixing plate is fixedly connected to the outer side of the end of the electric push rod.
[0017] As a further description of the above technical solution:
[0018] Both sides of the top of the base are fixedly connected to support columns 2, and both support columns 2 are slidably connected to placement plates on their inner sides.
[0019] As a further description of the above technical solution:
[0020] The inner sides of both ends of the connecting plate are fixedly connected to the outer sides of the two belts;
[0021] As a further description of the above technical solution:
[0022] Both ends of the base are equipped with track wheels.
[0023] This utility model has the following beneficial effects:
[0024] 1.

Detailed Implementation
[0033] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0034] Reference Figure 1 and Figure 2 An embodiment of this utility model is provided: a warehouse robot with a lifting structure, including a base 1 and a placement plate 3. Lifting components are fixedly connected to both ends of the top of the base 1. A forward and backward moving component is provided at the bottom of the placement plate 3. A pushing component is provided on the inner side of the placement plate 3. A hollow plate 15 is provided at the top of the placement plate 3. A driving component is provided on the inner side of the hollow plate 15. A positioning component is provided at both ends of the hollow plate 15.
[0035] The lifting assembly includes a support column 6, which is fixedly connected to the top of the base 1. A drive motor 7 is fixedly connected to the outer side of the end of the support column 6. Pulleys 8 are rotatably connected to the inner sides of both ends of the support column 6. The output end of the drive motor 7 is fixedly connected to the inner side of one of the pulleys 8. A belt 21 is fitted onto the inner side of both pulleys 8. The drive motor 7 is activated, causing the connected pulley 8 to rotate. Since the two pulleys 8 are connected by the belt 21, and the connecting plates 10 at both ends of the placement plate 3 are fixed to the outer side of the belt 21, the belt 21 moves accordingly when the pulleys 8 rotate, causing the placement plate 3 to rise or fall along the support column 9. The support column 9 acts as a guide, ensuring that the placement plate 3 maintains a stable vertical movement trajectory during lifting, enabling the lifting operation of goods placed on the placement plate 3 to adapt to the storage and retrieval needs of shelves of different heights.
[0036] Reference Figure 1 and Figure 3The forward and backward moving assembly includes a connecting plate 10, which is fixedly connected to the outer end of the placement plate 3. A housing 11 is fixedly connected to the side of the connecting plate 10. Two gears 12 are rotatably connected to the inner side of the housing 11. A second drive motor 13 is fixedly connected to the top of the connecting plate 10. The output end of the second drive motor 13 is fixedly connected to the inner side of one of the gears 12. Toothed plates 14 are slidably connected to the outer ends of both ends of the housing 11. The two gears 12 are meshed with the outer sides of the two toothed plates 14, and the two toothed plates 14 are slidably connected to the inner side of the connecting plate 10. In the forward and backward moving assembly, the forward and backward movement of the toothed plates 14 directly drives the pusher plate 4 to perform a forward and backward pushing operation on the placement plate 3. The pusher assembly includes a pusher plate 4, which is fixedly connected to the ends of the two toothed plates 14, and its middle part is slidably connected to the inner side of the placement plate 3. When goods need to be placed deep into the shelf or pulled back onto the placement plate 3, the push plate 4 will perform the corresponding pushing action under the drive of the toothed block plate 14 to ensure that the goods can smoothly enter and exit the shelf space.
[0037] Reference Figure 1 and Figure 4 The drive assembly includes a dual-head motor 17, which is fixedly connected to the inner side of a hollow plate 15. The hollow plate 15 is fixedly connected to the top of a push plate 4. Connecting shells 16 are fixedly connected to both ends of the hollow plate 15. Worms 18 are rotatably connected to the inner sides of both connecting shells 16. The output ends of the dual-head motor 17 are fixedly connected to the ends of the two worms 18. Worm wheels 19 are rotatably connected to the inner sides of both connecting shells 16, and both worm wheels 19 are meshed with the outer sides of the two worms 18. When the dual-head motor 17 starts, it drives the worms 18 at both ends to rotate. The worms 18 mesh with the worm wheels 19, causing the worm wheels 19 to rotate. When the worm wheels 19 rotate, the electric push rod 5 changes its angle and position as the worm wheels 19 rotate, thereby causing the fixed plate 20 to move and change its angle simultaneously. The positioning component includes an electric push rod 5, which is rotatably connected to the inner side of the connecting housing 16. The outer end of the electric push rod 5 is fixedly connected to the inner side of the worm gear 19, and a fixing plate 20 is fixedly connected to the outer end of the electric push rod 5. When goods are placed on the shelf or removed from the shelf, the position of the fixing plate 20 can be precisely controlled by adjusting the extension and retraction of the electric push rod 5 and the rotation of the worm gear 19, so as to position and clamp the goods, prevent the goods from shifting or falling during the movement of the warehouse robot, and ensure the stability and safety of goods transportation and storage.
[0038] Reference Figure 1 , Figure 2 and Figure 5The base 1 has two fixed support columns 9 on its top sides, and two placement plates 3 are slidably connected to the inner sides of the two support columns 9. These are used to enhance the stability and lifting of the placement plates 3. The inner sides of both ends of the connecting plate 10 are fixedly connected to the outer sides of the two belts 21. This allows the belts 21 to drive the placement plates 3 to rise and fall via the connecting plate 10 when they are in motion. Track wheels 2 are provided at both ends of the bottom of the base 1 for overall movement.
[0039] Working principle: First, the drive motor 7 starts, driving the connected pulley 8 to rotate. Since the two pulleys 8 are connected by a belt 21, and the connecting plates 10 at both ends of the placement plate 3 are fixed to the outside of the belt 21, the belt 21 moves accordingly when the pulleys 8 rotate, causing the placement plate 3 to rise or fall along the support column 9. The support column 9 acts as a guide, ensuring that the placement plate 3 maintains a stable vertical movement trajectory during lifting and lowering, thus enabling the lifting operation of goods placed on the placement plate 3 to meet the storage and retrieval needs of shelves of different heights.
[0040] In the forward and backward movement assembly, the forward and backward movement of the toothed plate 14 directly drives the pusher plate 4 to push back and forth on the placement plate 3. When it is necessary to place goods deep into the shelf or pull goods on the shelf back onto the placement plate 3, the pusher plate 4 will perform the corresponding pushing action under the drive of the toothed plate 14 to ensure that goods can smoothly enter and exit the shelf space.
[0041] The dual-head motor 17 starts, driving the worm gears 18 at both ends to rotate. The worm gears 18 mesh with the worm wheel 19, causing the worm wheel 19 to rotate. When the worm wheel 19 rotates, the electric push rod 5 changes its angle and position accordingly, thereby causing the fixed plate 20 to move and change its angle. When goods are placed on the shelf or removed from the shelf, by adjusting the extension and retraction of the electric push rod 5 and the rotation of the worm wheel 19, the position of the fixed plate 20 can be precisely controlled, enabling it to position and clamp the goods, preventing displacement or falling during the movement of the warehouse robot, and ensuring the stability and safety of goods transportation and storage.
[0042] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
