Description

Technical Field

[0001] This utility model relates to the field of material handling robot technology, and in particular to an intensive warehouse material handling robot. Background Technology

[0002] With the rapid development of e-commerce, manufacturing and other industries, the scale of warehousing has continued to expand, and the amount and types of goods stored have increased dramatically. Intensive warehousing has become one of the mainstream warehousing forms because it can maximize the use of warehousing space (30%-50% higher than traditional warehousing space utilization). However, the characteristics of intensive warehousing, such as narrow aisles, dense storage locations and increased stacking height of goods, also bring many challenges to handling operations. Traditional methods such as manual hauling or using electric haulers are gradually becoming unable to meet the needs of efficient and stable operations. While conventional handling equipment can reduce manpower, it typically uses electric pallet trucks to directly transport goods by inserting a single pallet. Due to the lack of layered load-bearing design, when transporting large quantities of items, the items must be stacked on a single pallet. If manual stacking is not done properly (such as shifting the center of gravity or tilting the stack), the items are prone to collapse during handling due to vibration or turning, resulting in damage to the items and interruption of operations. Therefore, improvements are needed to address these issues. Utility Model Content

[0003] The purpose of this invention is to address the shortcomings of existing technologies by proposing an intensive warehouse handling robot.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: a high-density warehouse handling robot, comprising a vehicle body, four wheels arranged in a rectangular pattern symmetrically on both sides of the vehicle body, two sets of loading frames symmetrically arranged on the top surface of the vehicle body, fixing holes at the four corners of the bottom end of the loading frames on the top surface of the vehicle body, each set of loading frames being composed of multiple vertically stacked parallel support plates at equal intervals, a fixing bolt threaded through the bottom support plate and screwed into the fixing hole, four electric telescopic rods arranged in a rectangular pattern between the opposite faces of the multiple support plates, and a limiting component provided at one end of the top surface of the support plate.

[0005] Preferably, the limiting component includes a vertical rectangular groove, in which a first lead screw is installed. A first motor is coaxially fixed to one end of the first lead screw. A sliding sleeve is sleeved on the first lead screw. A limiting half-ring is fixed to one end of the sliding sleeve. A limiting plate is hinged to the upper end of the other end of the sliding sleeve. One side of the limiting plate abuts against the limiting half-ring. A torsion spring is sleeved at the hinge axis of the limiting plate.

[0006] Preferably, the top surface of the bearing plate is provided with a barrier composed of multiple sets of telescopic sleeves, the fixing sleeve of the telescopic sleeve is fixedly connected to the top surface of the bearing plate, and the telescopic plate of the telescopic sleeve is fixedly connected to the bottom surface of the adjacent bearing plate.

[0007] Preferably, a transverse rectangular groove is formed in the middle of the top surface of the bearing plate, and a second motor is installed inside the transverse rectangular groove. The output shaft of the second motor is coaxially fixed to a second lead screw, and a sliding block is sleeved on the second lead screw. The sliding block has a T-shaped cross section.

[0008] Preferably, the top surface of the vehicle body is provided with multiple hook grooves.

[0009] Preferably, the telescopic sleeve is located between the opposite faces of the four electric telescopic rods and is C-shaped when viewed from above.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows: This utility model, through the cooperation of multiple load-bearing plates of the loading frame and four electric telescopic rods, facilitates the adjustment of the spacing between adjacent load-bearing plates according to the height of the items, improving the flexibility of the load-bearing space and enabling layered load-bearing of items; furthermore, through the cooperation of the bottom load-bearing plate with fixing bolts and fixing holes on the top surface of the vehicle body, it facilitates the stable fixing of the loading frame to the vehicle body, improving the stability of the layered load-bearing structure, thus enabling a large number of items to be distributed and placed on different load-bearing plates, avoiding concentrated stacking; through the cooperation of the limiting components on the top surface of the load-bearing plates, the first motor drives the first lead screw to rotate, causing the sliding sleeve to move vertically along the top view to adjust the limiting position. The limiting semi-ring at one end of the sliding sleeve and the limiting plate hinged at the other end form a bidirectional blocking, and the torsion spring compresses when the item is pushed in and drives the limiting plate to reset when the item tends to detach, facilitating a stable limiting according to the width of the item, improving the adaptability of item fixing, and thus enabling stable limiting of items of different widths; furthermore, through the cooperation of the load-bearing frame with the fixing bolts and four electric telescopic rods, it facilitates the stable fixing of adjacent load-bearing plates according to the height of the items, improving the adaptability of item fixing, and thus enabling stable limiting of items of different widths; furthermore, through the cooperation of the load-bearing frame with the fixing bolts and four electric telescopic rods, it facilitates the adjustment of the spacing between ... The sliding block on the carrier plate works in conjunction with the second motor and the second lead screw. The second motor drives the second lead screw to rotate in the opposite direction, pulling the sliding block back. This allows the sliding block to abut against the bottom of the item, reducing the space for swaying and improving the stability of the item's bottom. This enables precise positioning and fixation of the item on the carrier plate. The telescopic sleeve on the top surface of the carrier plate works in conjunction with the electric telescopic rod, allowing the telescopic sleeve to extend and retract synchronously with the spacing of the carrier plates. This improves the adaptability of the enclosure and provides lateral protection for items at the edges of the carrier plate. Furthermore, the C-shaped design of the telescopic sleeve, when viewed from above, works in conjunction with the carrier plate to ensure that loading and unloading of items is not affected and to prevent items from slipping off the sides. This improves the practicality of the protection and enables all-round protection for layered items. Ultimately, this solves the problems of ordinary electric pallet trucks lacking layered design, easy collapse of items stacked on a single board, poor item fixation and easy slippage due to vibration in traditional handling equipment, as well as lack of protection and easy items falling off the sides. This improves the stability, safety, and integrity of item handling. Attached Figure Description

[0016] Working Principle: In the use of this utility model, firstly, the robot's movement and positioning are achieved by the four wheels 2 arranged in a rectangular pattern on both sides of the vehicle body 1. The symmetrical distribution of the four wheels 2 ensures the stability of the vehicle body 1 during movement. According to the layout of the storage channel and the location of the target cargo location, the vehicle body 1 can be moved precisely to the storage location or unloading point of the goods to be transported, providing basic positioning support for subsequent loading and unloading operations. Before loading the goods, the carrying space of the loading rack 3 needs to be adjusted according to the height and quantity of the goods. The four electric telescopic rods 5 between the opposite surfaces of the multiple carrying plates extend and retract synchronously, which can drive each carrying plate to move up and down in the vertical direction, realizing flexible adjustment of the distance between adjacent carrying plates. When transporting taller items, the electric telescopic rods 5 extend to increase the carrying capacity. The spacing between the plates is adjusted so that when handling small items, the electric telescopic rod 5 shortens to reduce the spacing, making full use of vertical space and adapting to the space utilization needs of dense storage. Simultaneously, the bottom support plate is bolted to the fixing holes 4 on the top surface of the vehicle body 1, ensuring a stable connection between the entire loading rack 3 and the vehicle body 1 during handling and preventing swaying. After the item is placed on the support plate, the limiting component activates to prevent the item from slipping during handling. The first motor 7 drives the first lead screw in the vertical rectangular groove to rotate, causing the sliding sleeve fitted on the first lead screw to move vertically along the length of the top surface of the support plate from a top-down perspective. The lateral position of the sliding sleeve is adjusted according to the placement and length of the item on the support plate to ensure that the limiting structure accurately corresponds to the item requiring limiting. When an item is pushed onto the carrier plate, it will push the limiting plate 6, which is hinged to the other end of the sliding sleeve, to rotate away from the limiting half-ring 12. At this time, the torsion spring 9 is compressed, ensuring that the item can smoothly enter the carrier plate. When the item tends to fall out, the torsion spring 9 releases its elasticity to drive the limiting plate 6 to reset, so that the limiting plate 6 abuts against the limiting half-ring 12 again. It works with the limiting half-ring 12 to form a two-way barrier, preventing the item from slipping during the robot's movement, and adapting to the fixing needs of items of different widths. In addition, the barrier and sliding block 11 on the top surface of the carrier plate further improve the loading stability and adaptability. The barrier composed of multiple sets of telescopic sleeves 8 extends and retracts synchronously with the extension and retraction of the electric telescopic rod 5. The fixed sleeve of the telescopic sleeve 8 is fixed to the top surface of the lower carrier plate, and the telescopic plate is fixed to... The upper adjacent support plate bottom surface provides lateral protection for items at the edge of the support plate. The telescopic sleeve plate 8 is located between the opposite faces of the four electric telescopic rods 5 and has a C-shaped design when viewed from above. This design does not affect the loading and unloading of items and can prevent items from sliding off the side of the support plate. When the item is placed on the support plate, the second motor 10 drives the second lead screw in the transverse rectangular groove to rotate in the opposite direction, which drives the T-shaped sliding block 11 to pull back laterally, so that the lower end of the item abuts against the sliding block 11. The cooperation between the sliding block 11 and the structure at the other end of the support plate reduces the swaying space at the bottom of the item and ensures that the item remains stable during transportation. At the same time, the T-shaped cross-section design can prevent the sliding block 11 from falling out of the transverse rectangular groove and ensure the stability of the adjustment process.Finally, the multiple hook slots on the top perimeter of vehicle body 1 can be used to hang auxiliary tools such as securing straps and labels. When handling items that are prone to shaking or require labeling, securing straps can be hung in the hook slots to further secure the items, or labels can be hung to indicate item information, improving the flexibility and practicality of handling operations, and ultimately achieving efficient and stable handling of items in dense warehousing scenarios; at this point, the device is complete.
