Description

Technical Field

[0001] This utility model relates to the field of automated warehousing technology, and in particular to an AGV suitable for narrow aisle racking in warehouses. Background Technology

[0002] With the continuous improvement of automation in modern logistics warehousing, Automated Guided Vehicles (AGVs) are increasingly widely used in warehouse management, especially in narrow aisle racking systems with high cargo density and limited operating space, where the flexibility and intelligent scheduling capabilities of AGVs are particularly crucial. To improve cargo handling efficiency and safety, developing AGV equipment suitable for high-precision operations in narrow aisle environments has become an important direction for the development of current warehouse automation technology. These AGVs must possess good spatial adaptability, path planning capabilities, and efficient and stable cargo loading and unloading capabilities to meet the operational needs of diverse warehousing scenarios.

[0003] In existing technologies, AGVs suitable for warehousing environments mostly adopt an integrated structure design of the vehicle body and the carrying platform. The vehicle body is driven by a motor to move along a set path, transporting goods from the storage location to a designated point. Loading and unloading typically rely on the docking of a platform at a set height with the racks, using roller conveyors, telescopic mechanisms, or forklift structures to complete the transfer of goods. To achieve compatibility with various racking systems, some AGVs adopt a standard height design, which still requires adjustments to the racks or pallets when operating at different storage heights. While the overall structure tends to be simple, its flexibility is limited.

[0004] However, existing AGV devices generally employ a fixed platform structure, making it difficult to adjust the loading and unloading angles according to specific working conditions when docking with racks of different heights. This easily leads to inaccurate docking and low loading and unloading efficiency. In confined, narrow aisle environments, this structure limits the equipment's adaptability to different rack levels, increases the probability of docking errors, and affects the overall intelligence and accuracy of the system. Therefore, there is an urgent need to optimize the structure to achieve adjustable platform angles and heights to improve loading and unloading accuracy and operational efficiency. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides an AGV suitable for narrow aisle warehouse racking, aiming to improve the problem of fixed load-bearing platform in the existing structure, which leads to limited loading and unloading angles and inaccurate cargo docking.

A second slide rail is slidably connected to the inner wall of the second slider. The upper surface of the second slide rail is fixedly connected to the lower surface of the bearing platform.

[0008] Furthermore, an extension plate is slidably connected to the inner wall of the bearing platform, a double-headed hydraulic rod is fixedly connected to the inner wall of the bearing platform, two slide rails are fixedly connected to the inner wall of the bearing platform, and sliders are slidably connected to the inner walls of each slide rail. A connecting plate is fixedly connected to one end of each slide rail, a connecting rod is fixedly connected to the output end of the double-headed hydraulic rod, and sliders are fixedly connected to the outer wall of the connecting rod. A connecting rod and a connecting rod are rotatably connected to the outer wall of the slider, and a fixing block is rotatably connected to the outer wall of the connecting rod. The upper surface of the fixing block is fixedly connected to the lower surface of the extension plate.

[0026] Reference Figure 1 - Figure 5 The present invention provides an embodiment of an AGV suitable for narrow aisle warehouse racks, including a body 3, which serves as the main structure of the AGV and plays the role of bearing and connecting various components. A lifting component is provided on the top of the body 3, and a base frame 4 and wheels 1 are connected below. An adjustment component is provided on the top of the body 3.

[0027] The adjustment assembly includes connecting rod 7 and connecting rod 8. Connecting rod 7 is connected to slider 15, fixed block 11, and rotating shaft 17, forming part of the lifting mechanism. Both connecting rod 7 and connecting rod 8 are located above the machine body 3. A slide rail 12 and fixed block 11 are fixedly connected to the inner wall of the machine body 3. An electric push rod 13 is fixedly connected to the inner wall of the machine body 3. The output end of the electric push rod 13 is connected to slider 6, which is used to drive it to move linearly along slide rail 12. Slider 6 is slidably connected to the outer wall of slide rail 12. The output end of the electric push rod 13 is fixedly connected to the outer wall of slider 6. The outer wall of slider 6 is rotatably connected to the inner wall of connecting rod 8. Connecting rod 8 pushes slider 6 to move through the electric push rod 13, causing connecting rod 8 to rotate, thereby... The lifting platform 9 is driven to complete the lifting action. The outer wall of the fixed block 11 is rotatably connected to the inner wall of the connecting rod 7. The inner wall of the connecting rod 7 and the connecting rod 8 are rotatably connected to the pivot 17. One end of the connecting rod 8 is rotatably connected to the fixed block 16. The fixed block 16 plays the role of bearing and supporting the platform, so that when the four-bar structure moves, it drives the platform to lift and lower synchronously. The upper surface of the fixed block 16 is fixedly connected to the lifting platform 9. One end of the connecting rod 7 is rotatably connected to the slider 15. The inner wall of the slider 15 is slidably connected to the slide rail 14. The upper surface of the slide rail 14 is fixedly connected to the lower surface of the lifting platform 9.

[0028] Reference Figure 1 - Figure 5An extension plate 10 is slidably connected to the inner wall of the bearing platform 9. The extension plate 10 can smoothly extend or retract, expanding the area of ​​the bearing platform 9 and improving its adaptability and stable bearing capacity for large and irregularly shaped goods. A double-headed hydraulic rod 18 is fixedly connected to the inner wall of the bearing platform 9. Two slide rails 19 are fixedly connected to the inner wall of the bearing platform 9. Sliding sliders 22 are slidably connected to the inner walls of slide rails 19. Sliding sliders 22 allow the extension plate 10 to smoothly unfold or return to its original position under the guidance of the double connecting rod. A connecting plate 25 is fixedly connected to one end of slide rail 19. A connecting rod 20 is fixedly connected to the output end of the double-headed hydraulic rod 18. Sliding sliders 22 are fixedly connected to the outer wall of connecting rod 20. Connecting rods 21 and 23 are rotatably connected to the outer wall of sliding sliders 22. The double connecting rod mechanism, which works in concert with connecting rods 23 and 21, provides multi-point support and synchronous guidance during the unfolding of the extension plate 10, preventing uneven force distribution or jamming. Connecting rods 21 are rotatably connected to the outer wall of connecting rods 21. There is a fixed block 24, the upper surface of which is fixedly connected to the lower surface of the extension plate 10. The lower surface of the machine body 3 is fixedly connected to the battery pack 2, which ensures the continuous operation of the AGV's lifting, expansion and other functions.

The machine body 3 is equipped with a charging port 5. The lower surface of slider 1 6 is slidably connected to the inner wall of the machine body 3. The upper surface of slider 2 15 is slidably connected to the lower surface of the bearing platform 9. The outer wall of connecting rod 1 7 is rotatably connected to the inner wall of connecting rod 2 8. Fixed block 1 11 is set on one side of the outer wall of slider 1 6. The sliding movement of slider 1 6 drives connecting rod 2 8 to rotate, thereby driving the entire four-bar linkage structure to realize the lifting and adjustment of the bearing platform 9. The outer wall of connecting rod 4 23 is rotatably connected to the inner wall of fixed block 24. Connecting rod 20 is set inside the bearing platform 9. Connecting plate 25 is attached to slider 3 22. The bearing platform 9 is set above the machine body 3.

[0029] Working Principle: When an AGV suitable for narrow aisle warehouse racking is needed, the height of the carrying platform 9 is adjusted by setting an adjustment component. First, a connecting rod 7 and a connecting rod 8 are set on the upper part of the machine body 3. The inner walls of the two are rotatably connected by a rotating shaft 17. One end of the connecting rod 7 slides on a slide rail 14 via a slider 15. The upper surface of the slide rail 14 is fixedly connected to the lower surface of the carrying platform 9 to achieve the guiding and limiting function. The other end is rotatably connected to the inner wall of the machine body 3 via a fixing block 11. One end of the connecting rod 8 slides on a slide rail 12 via a slider 6. The lower surface of the slider 6 can move along the inner wall of the machine body 3. The output end of the electric push rod 13 is fixedly connected to it. The electric push rod 13 drives the slide rail 12 through control. Block 6 performs linear reciprocating motion, thereby driving the second link 8 to rotate. The other end of the second link 8 is rotatably connected to the second fixed block 16. The upper surface of the second fixed block 16 is fixedly connected to the lower surface of the bearing platform 9. When the electric push rod 13 is started, its output end pushes the slider 6 to move along the slide rail 12, thereby causing the angle of the four-bar structure composed of the first link 7, the second link 8 and the rotating shaft 17 to change, driving the bearing platform 9 fixedly connected to the end of the link to achieve overall lifting and lowering. By changing the extension and retraction of the electric push rod 13, the platform height can be adjusted to the preset position, realizing precise docking and loading and unloading with shelves of different heights, improving loading and unloading efficiency and automated docking accuracy, and avoiding the problem of cargo transfer angle deviation caused by fixed height.

[0030] In addition, to improve the stability and stress uniformity of the platform when transporting large or irregularly shaped goods, this device is equipped with an extension plate 10 structure. The platform area is expanded and adjusted through a sliding telescopic mechanism. The extension plate 10 is located inside the bearing platform 9, and its lower surface is rotatably connected to connecting rods 21 and 23 via a fixed block 24. The rotatable hinge between connecting rods 21 and 23 forms a double-linkage guide support mechanism, ensuring a smooth and synchronous expansion process. The sliding guide section uses two slide rails 19 mounted on the inner wall of the bearing platform 9. Sliding sliders 22 are slidably connected to the two slide rails 19 respectively. A connecting rod 20 is fixedly connected to the outer wall of the sliding slider 22. The middle of the connecting rod 20 is driven by a double-headed hydraulic rod 18 for drive control. When it is necessary to expand the platform area, the control... The double-headed hydraulic rod 18 extends, pushing the connecting rod 20 to simultaneously drive the slider 22 to slide out along the slide rail 19 and abut against the connecting plate 25 at the tail end of the slide rail 19. At the same time, the slider 22 rotates, causing the connecting rod 21 and the connecting rod 23 to unfold, thereby causing the extension plate 10 fixed at its end to extend outward smoothly, expanding the usable area above the carrying platform 9. When retracting, the double-headed hydraulic rod 18 retracts, and the extension plate 10 returns to its original position under the guidance of the connecting rod structure. This structure not only expands the platform area to meet the carrying requirements of goods of different specifications, but also ensures that the goods are evenly stressed and have a stable center of gravity during transportation through symmetrical sliding and multi-point guidance, reducing the safety risks caused by goods shaking or shifting, and improving the practicality and transportation reliability of AGV in narrow aisle storage scenarios.
